Questions you should ask to doctor for Alzheimer disease

Posted: July 7, 2013 at 2:54 am


Alzheimer’s Disease is a critical health condition that cannot be defined in a specific way.It is a very common form of Dementia. Dementia in itself is not a disease. Rather, it is a group of symptoms that start occurring due to occurrence of some other disease or medical condition.Person suffering from Alzheimer’s Disease can face difficulty in remembering even the most recently happened events. This is the initial stage. The disease can lead to death of a person too! The disease starts to occur in people who have crossed 65 years of age or more. Those who get diagnosed with this difficult disease, a good doctor needs to be consulted at the earliest. There are certain questions that need to be placed before the doctor related to the disease. Some of the most important questions are listed below:

What is the usual course of the Alzheimer’s disease?

Life long.

What type of new treatments are available?

Since it is not a disease, there is no particular treatment available. However, some medicines are available but that too works at the early stages.

Are the drugs used to treat the AD symptoms effective?

Yes, at times and mostly during the early stages.

Does these drugs have any sort of side effects?

At time, yes. It can cause poor eyesight problem, gaining weight, as well itching problems.

Does the AD affects a person for the remaining part of his/her living days?

Yes, definitely.

What is the total time period for a person to act in a very normal way post Alzheimer’s diagnosis?

The first and middle stages are still OK with the patients. Although slight changes start taking place but still the behavior doesn’t get completely out of the mark. But, once the patient reaches advanced stage, scenarios tend to become more complicated.

Can a patient of Alzheimer’s Disease be a threat to other or themselves?

The Patient can be a real threat to him/herself. At advanced stage, the patient can even forget her/his own address, name, etc. Scenarios can get real complicated when the patient fails to identify his/her relatives, family members and friends.

Is home or nursing home the best place to take care of the person suffering from AD?

No, there is no such a thing. A lonely person with no one to take care of can stay best in a nursing home. But a person with good family and friends can easily stay in the home. Alzheimer’s is a not a disease but a syndrome that can be as deadly as any other disease. But, there is no specific treatment for it. So, there is no need to spend unnecessary money booking a bed in the nursing home.

What are the necessary precautions to take in order to make the home surroundings safe for someone who has been diagnosed with Alzheimer’s?

A clean surrounding can definitely help. The person suffering from AD should be kept stress free. The patient should have more interaction with family members and friends. However, by no means the patient should be made excited or furious. It can provide extra stress on the brain. This can cause some negative repercussions.

What are the best available support and services are available in the local area related to Alzheimer’s disease?

This is a very important question to ask the doctor. Remember, if local medicinal help can be availed, then much of worries are eliminated.

Is Alzheimer’s considered a hereditary disease?

Yes, definitely. But it is only a small part of the bigger process. AD can develop due to several factors, most important being strong stress.

How good to use home pregnancy tests

Posted: June 2, 2013 at 2:54 am


Home pregnancy tests have been practiced for long by women and is quite trusted way of confirming your doubts when it comes to conceiving. Here are certain signs that can tell you that you are probably pregnant.

If you have missed your period or you are having an abnormal or unusual period may be you are pregnant. If you have got frequent urinating tendencies or you throw up (vomit) again and again it is possible that you are pregnant. Generally women tend to lose their control over bladder when pregnant; it is very hard to control excretion of urine. Morning sickness or nausea is a tendency that is observed in pregnant women. They cannot resist throwing up again and again during the second and third months of pregnancy. Enlargement or soreness in breast is also indicates that possibly you are pregnant. Breast starts to grow big and become painful. If your breast is releasing colostrums, uterus is enlarged or you are getting a lot of stretch marks there is a possibility that you may be pregnant. In case you have frequent strange cravings like you have never had in past may be a n indication that you are pregnant.

However, these are not confirmed signs of pregnancy. Some of these symptoms when experienced together increase the probability of one’s pregnancy. You should immediately rush for a pregnancy test if you are even a little doubtful. This will clarify your doubts as it is a reliable way to test your pregnancy by yourself. You can also trace the pregnancy by an ultrasound test but home pregnancy strip test is more handy, cheap and reliable.

In case you are planning to conceive these are some symptoms that might be pointing towards your positive result on a pregnancy strip. Be happy you are experiencing such phenomenon and consult a doctor as soon as possible. Apart from all this reflect on your inner sight you can feel it when you are pregnant and the tests suggested above are just a primary confirmation.

In case you do not want to bear there are ways to get out of the web. Contraceptive pills are available in the market which can be a help in forbidding any pregnancy. There are pills that you can take within 72 hours after having unprotected sex to prevent pregnancy but its intake again and again can cause side effects. If you detect a positive on the pregnancy strip, you will have to abort it whether it is by an abortion pill or by any other method.

Are Biodegradable Heart Stents Safe?

Posted: April 21, 2013 at 2:56 am


A breakthrough has been achieved in the stream of medical science. An alternative to the metallic stent has been found and is called biodegradable or bio-absorbable stents.

Difference between the two

Metallic stents which are in use for a long time now, had some disadvantages. These stents helps to keep the blocked arteries open to enable the flow of oxygen and blood, but also causes retenosis, that is, it scars up vessel tissue causing the arteries to clog again. Even though drug infused metallic stents have also been used as an alternative, it still does not lower the risks of other complications.

Biodegradable stents, on the other hand causes no such complications. It opens up the blocked arteries and dissolves itself after fulfilling its task, thus, minimizing the occurrence of any complication. It is made up of poly-l-lactide, a naturally dissolving material. It is said to dissolve in a time span of 18 months to three years. Another advantage of this stent is that it does not prevent the detection of other blockages as opposed to the metallic stents which would refract the rays of the scan, making it hard for detection.

Benefits of not having a permanent stent

One of the greatest benefits of not having a permanent stent is that it allows the lumen to expand. When a permanent metallic stent is used it does not allow the lumen to grow, thus hindering remodeling even though it allows the vessel around the stent to develop.

Another benefit is they do not produce any kind of inflammatory reactions as opposed to metallic stents.

How does a biodegradable stent work?

Arteries start getting clogged up due to the accumulation of fatty matter like chlorestol on the inner wall of the arteries that are responsible for providing blood to the heart. As it advances, it reduces the width of the lumen in return diminishing the amount of blood flowing into the heart. This is when a person undergoes a chest pain known as angina.

This disease can be arrested at the initial stage with the help of medication. But a person suffers a heart attack when the precautions are not taken, or when the artery is fully obstructed. That is when the surgical procedure of angioplasty is done. In angioplasty, a balloon is introduced into the artery through a guide wire and is inflated where the blockage is located. After this the stent is introduced so that it keeps the artery open.

The biodegradable stent releases a drug called everolimus which prevents irregular tissue growth.

Researches and studies that classify biodegradable as safe

Kunhiko Kosuga, who has a MD, PhD and is also the director of cardiology at Shiga Medical Center for Adults in Moriyana City, Japan, did a research on these new stents. He and his fellow researchers studied 44 men and 6 women who had undergone angioplasty and had used biodegradable stents to open up the affected arteries. They looked for various complications like clots, deaths, and other causes. The result is as follows:

? for the deaths associated with heart diseases, the survival rate was 98%.

? for death from all causes, the survival rate was 87%.

? there was no main cardiac problems in half the patients.

? Only four patients suffered heart attacks.

? The blood vessel involved had re-narrowed in 16% of the patients, in one year after undergoing the procedure.

? there were two clots that were found within the stent. One was due to the drug-infused stent close to the biodegradable one.

Countries who welcomed biodegradable stents

Nine European countries, Middle East, parts of Latin America and parts of Asia like India, Hong Kong, Philippines and Vietnam are already using these stents. In Europe, Asia-Pacific, Canada and Latin America, over 600 patients have taken part in the trial which aspires to have 1000 patients from over 100 centres present in these counties. Even Singapore has approved of these stents from 20th December, 2012.

However, doctors are still awaiting results for the long term effects on the patients

Even though the cost for manufacturing these stents is very expensive, doctors worldwide are optimistic that they will replace metallic stents eventually.

The Mystery about Cyanide Taste

Posted: April 14, 2013 at 2:57 am


What is potassium cyanide??

A chemical compound with the chemical formula KCN is commonly known as the Potassium cyanide. This is a colorless crystalline compound, highly soluble in water and is similar in appearance as that of sugar. Potassium cyanide is considered to be highly toxic in nature. Potassium cyanide is considered to be one of the most deadly compounds being discovered till date.

Production of Potassium Cyanide:

Potassium Cyanide can be produced mainly by treating hydrogen cyanide in the presence of a fifty percent of an aqueous solution of potassium hydroxide. After that the aqueous solution is either evaporated in a vacuum or by treating the form amide in the presence of potassium hydroxide. On an average per year approximately fifty thousand tons of potassium cyanide are being produced all over the world.

Use of Potassium Cyanide:

Potassium Cyanide is mainly used for the purpose of electroplating, organic synthesis of a number of chemical compounds, gold mining and so on. In accordance with the large scale use of Potassium Cyanide, it is also used in smaller scale applications like in the jewelry manufacturing industry for chemical buffing and gliding. Other than those mentioned earlier, Potassium Cyanide is also used by the entomologists as it is an excellent killing agent, and it has the unique capability of causing minimum damage to the highly fragile specimens.

Mystery about Potassium Cyanide:

Since, the time of its invention, the biggest mystery that has been surrounded with Potassium Cyanide, is about the taste of it. Due to the fact that Potassium Cyanide is exceedingly poisonous substance and can cause death of a person in seconds, the taste of it has remained a mystery or a fact yet to be known to the world. Though, many researches and tests have been conducted to find the taste of Potassium Cyanide but none of them could come up with the appropriate result.

Different views about the taste of Potassium Cyanide:

There has been number of views among the scientists about the taste of the Potassium Cyanide, some of them are as follows:

· Since on hydrolysis of KCN, the resultant compound that are formed are KOH and HCN, which are strong base and weak base respectively, Potassium Cyanide is confirmed to be basic nature. Since at room temperature HCN is a gas which evolves and the solution is expected to have more KOH, so the taste of Potassium Cyanide is assumed to be bitter.

· Some, scientists who have died while finding the taste of Potassium cyanide, could only write the alphabet “S” before dying, so it is not conclusive whether it is sour, sweet or salty in taste.

Conclusion:

Though, a huge number of scientists sacrificed their lives in order to find the taste of Potassium cyanide, but it remained a mystery for long, until and unless a goldsmith from India named MP Prasad in an attempt to commit suicide with the help of Potassium cyanide could finally reveal the taste of Potassium cyanide. As per the suicide note of him the taste of Potassium Cyanide is very much acrid, that is irritatingly harsh and sharp. This fact about the taste of Potassium cyanide is approved by the World Health Organization and is marked as an extraordinary discovery in the field of science.

DNA testing is Good or Bad: Let’s Discuss

Posted: March 10, 2013 at 3:15 am


DNA, deoxyribonucleic acid it is the backbone of all living creatures on earth. It is a molecule, which is having a double helical structure and encoded with genetic instructions. It leads to the functioning of all living beings including viruses. DNA profiling is done by the forensic scientists. It depicts the nature of the DNA and act as a person identifier. By knowing the genomic sequences a scientist could easily predict the DNA of the person.

Identification Of Diseases

In this era this technology has become a boon or us in many ways. This concept of DNA testing is booming in the market like anything. It has become the latest rage specially in the health care market. Many companies are there who will promote you the test kits and let you know about the diseases like cardiac problem, any alzimers syndromes, any indication of breast cancer if have any. But here comes the argument many feeble minded people are there who will completely go against it. As the procedures includes blood testing and many people are phobic of syringes, then comes the acceptance of the disease if have any.

Benefits of DNA testing

Many women in our country are facing problem with breast cancer. As they are afraid of testing their blood and DNA. They don’t have the exact DNA marker. This is a big concern for the physicians as well. It is always recommended having a DNA testing for a healthy life. The risk factors get decreased than before and longevity will increase. Myopic thinking should be removed from the society and should learn to accept the truth. DNA testing will also give information about the allergic reaction with various pathogens. The life will be in a proper and better shape.

Detection of criminals

Normal people have a vague idea about this DNA testing which is not at all harmful. Through DNA testing crimes can also be detected. Like in the forensic lab the victim’s body will undergo a scrupulous check up and easily it will be detected about the death of the person. Many criminal lawyers take support from this process which make their job easy to detect the criminal. Though it’s not a good indication for the crime masters. By taking the blood sample or from the foot steps even, of the suspected person it will unveil the truth of the real murder. It can save our nation from crimes.

Detection of pregnancy

Many unrevealed and awful activities like rape case, illegal affairs lead to pregnancy. In many cases the male denied for becoming a father. The lady could easily raise her voice for justice, here

Comes the major role of DNA testing which will easily catch hold of the real father. Sometimes it is not safe for the pregnant woman to have DNA testing as it might cause harm to the fetus. The illegal activities in our society have inflated than before so DNA testing should play a vital role in the society of crimes.The lady will get justice and to deliver her baby.

As a whole it’s a win-win situation because some hospitals testing the DNA of the fetus take place, as an outcome they reveal the gender, which might lead to a death of a baby girl.This is an illegal activity. Some lawyers are also against this. But in this contemporary era one must believe in DNA testing to save our nation.

Things to know about the real fountain of youth

Posted: January 20, 2013 at 7:47 am


Fountain of youth is referred to a spring. If a person drinks the water of it, he or she can easily restore the youth again in themselves. In his writing Herodotus has also mentioned about this concept. This has become a kind of legend and many a famous author like Homer or Shakespeare have also discussed about in the literature. Now the biggest question is that whether there is really any kind of such fountain on this earth or not.

How the search goes on:

The search of such a fountain goes generation after generation because men have always wanted more youth. With the progress of science men have made many an incredible thing successful. The use of stem cells and many other related inventions have made huge change in human life. Men and women are getting longer and fitter life. More researches on cells are going on and scientists are working very hard to invent various things by the help of which we can keep our youth for longer time.

What the concept is:

Though the whole thing comes from a myth but the main aspect of this thought is to get back the life again. Man has always searched for immortality. According to scientists, now they have found out a way to continue your youth for longer time. Actually our body can have the charm of youth because of cell division. Normally a cell can divide for fifty times and then gradually it stops and the characteristics of old age begin to come in the body. Now the scientists have succeeded to produce such a cell which can divide it over 90 times and still it will not get slow down. Scientists have used an enzyme with the chromosomes the name of which is Telomerase. Telomere shortening is the actual reason of gradually getting old. Now this enzyme will stop the normal shortening process of telomere and thus it can help you to keep your youth in yourself for longer time.

Its drawback:

This enzyme is undoubtedly one of the most incredible inventions at the moment but it may have some drawbacks. According to some of the scientists this shortening process of telomere is a natural process. Now this natural process can eventually ward off cancer. Now by adding this enzyme this natural process of body defense will be destroyed. Some of the scientists are worried of the consequences of that. More experiments are going on and after the successful completion of them the scientists will be able to state the result of this new invention.

Searching for longer life:

Most of the people on this earth like to have a longer life especially a longer youth in which he will have ample energy to enjoy all the entertaining aspects of life. The concept of fountain of youth has been traditionally carried forward generation after generation because of this continuous wish of longer life of human being.

The myth of finding a fountain where the water can be found which can bring back youth may not be found physically. However, progress of science can assure a longer youth for human. In recent future man is going to live a longer enjoyable life.

Top trends for Biotechnology

Posted: December 9, 2012 at 7:49 am


Biotechnology simply means to develop or to make useful products with the help of using living systems. Over the years mankind has used biotechnology in several sectors like agriculture, food production and medicine. There are several sectors in which biotechnology can affect severely.

Biotech for human enhancement is the most profitable industry in the 21st century. Careers are influenced by genetic heritage. It is said that by 2020 people will be able to decipher human genome

Which is nothing but the blueprint of our DNA? One of the trends is towards the genetic solutions to the ills. There are several newly discovered drugs will save countless no of lives. These drugs can also eliminate many diseases. A lot of research works have been done on the recent trends for biotechnology. Research output continues to shift to ASIA. The current trends in biotechnology are its association with pharmacy. It is said that within few more years people will be able to turn on or turn off certain genes which can influence on health and performance. People can eliminate unwanted characteristics by using altered genes from their babies. People can also enhance their babies’ capabilities by using the same method. There is different classification of biotechnology having different application of each. Like white or industrial biotechnology helps in the production of chemical base materials and end products. Red biotechnology means development of new medical drugs. Biotechnology is the driving factor behind many applications in medicine. Green or Plant biotechnology is used in production of plants which are renewable recourses. Biotechnology is integrated use of many biological technologies. It also has trends in horticulture. One of the emerging trends in Biotechnology have been observed and noted in recent years. One such trend is the trend in partnering and acquisition of deals. This is applicable to the business perspective towards the delivery and realization of more up to date by products. So basically there are a lot of sectors in which biotechnology can affect. But one of the most suitable choices is pharmaceutical sector. People are focusing more and more now days on the use of biotechnological products. There are a lot of independent biotechnology companies which deals directly with these biotechnological products. Biotechnology is used to develop commercial product also. Biotechnology becomes central priority of the government’s research policy to ensure a high standing of biosciences and to develop newer innovation techniques. At present there are 25 different initiatives to financially support universities, research institutes. They all are working like a chain having same common objectives. There is a healthy competition in between the companies which in turn increases the level of biotechnological products. The key element of this initiative is Biopharma competition. So it depends on the people how they utilize biotechnological products for their better interest.

Biotechnology is a technology which never goes opposite to the nature.

We have to improve the biotechnology with the help of nature. Now a days lots of course are based on Biotechnology in various colleges all over the world. It becomes popular to all the students also.

Biotechnology: Things you should know about Gene Therapy

Posted: December 2, 2012 at 7:47 am


Introduction

Genetic disorders are becoming common nowadays due to stressful modern lifestyle. Latest technologies are the added values to create many genetic disorders. To overcome the disorders, Gene therapy is a blessing. In order to compensate abnormal genes and make a good gene, genetic material is introduced into cells. In this way, mutated gene will act as a normal gene. Let us see in detail.

Ways to insert the gene

There are indirect ways need to be followed to make a gene to function as if it is inserted directly does not function. Carrier also called as vector is used to deliver the gene. In the place of vectors, virus play the role as they are getting modified and hence people are not affected with new diseases when it is integrated into the chromosome of the human cell.

The vectors need to get injected to specific tissue in the body or outwardly patient’s cell is removed and exposed to the vector. In either of the ways need to be again returned to the patient. Successful treatment makes proper genes and genetic disorders get solved.

Gene therapy for treating cancer

Cancer is the dangerous disease and there are many ways to cure cancer including surgery, chemotherapy, and radiation. But cancerous cells in due course again spread and hence it is a deadly disease. Gene therapy is the best way discovered nowadays for treating cancer.
Let us see the basic fundamentals of cells. cells include packets of data in genes, created either from DNA or RNA. Sequence is there for DNA and if it is in the order, there will be no problem. But at the same time If there is disorder occurs in portion of the genes either turning or changing the position, cells lost their control and abnormal growth is seen which result in cancerous tumors. It can spread in mouth, breast, lung etc.,

Specialists in Gene therapy analyze the patient’s criticality first and follow the treatment procedures. One way is they replace missing or mutated genes into wholesome genes. Inserting totally new genes for fighting cancer, placing DNA into cancerous cells to undergo chemotherapy and radiation or injecting bad gene to destroy them etc., Mesothelioma type of cancers are not at all responded in formal therapies and hence one need to undergo gene therapy essentially. Need to have consultations with doctors to overcome their deadly disease.

Gene therapy importance

Doctors decide whether gene therapy is suitable by the following approaches. If genetic disorders are from mutations in one or more genes or whether a normal copy of the gene that is available in the patient is enough to fix the problems in the affected cells, then doctors determine that gene therapy will be more helpful rather than going for traditional methods.

Conclusion

Genetic engineering is a vast topic. Latest Science innovations in the field of genetic engineering yields for gene therapy. Doctors and scientists together working to find out whether gene therapy is the best suitable way for treating deadly diseases like cancer and others. Let us salute for the positive force of gene therapy.

The Future of Agricultural Biotechnology

Posted: at 10:02 am


USDA’a Advisory Committee has prepared a report titled ‘Opportunities and Challenges in Agricultural Biotechnology: The Decade Ahead’ which talks about the advancements made by agricultural biotechnology in the first decade and the future of it over the next ten years. As of now it is difficult to predict which modern biotechnology generated animals or plants we would be able to see in the market in the next ten years but some of the possibilities have been stated in the report and they have been mentioned below: (1) Genetically engineered plant varieties that provide improved human nutrition (e.g., soybeans enriched in omega-3 fatty acids) (2) Products designed for use in improved animal feeds (providing better nutritional balance by increasing the concentration of essential amino acids often deficient in some feed components, increased nutrient density, or more efficient utilization of nutrients such as phosphate that could provide environmental benefits) (3) Crops resistant to drought and other environmental stresses such as salinity (4) Crops resistant to pests and diseases (e.g., fusarium-resistant wheat; chestnut-blight resistant chestnut; plum pox resistance in stone fruit; various insect resistant crops) (5) Additional crops containing a number of transgenic traits incorporated in the same plant (stacked traits) (6) Crops engineered to produce pharmaceuticals, such as vaccines and antibodies (7) Crops engineered for particular industrial uses (e.g., crops having improved processing attributes such as increased starch content, producing useful enzymes that can be extracted for downstream industrial processes, or modified to have higher content of an energy-rich starting material such as oil for improved utilization as biofuel) (8) Transgenic animals for food, or for production of pharmaceuticals or industrial products (e.g., transgenic salmon engineered for increased growth rate to maturity, transgenic goats producing human serum factors in their milk, and pigs producing the enzyme phytase in their saliva for improved nutrient utilization and manure with reduced phosphorus content).

Making Nanotechnolgy Safer for Breast Implants

Posted: May 6, 2012 at 3:48 pm


For more than 20 years, the main choice for breast implants has been some form of silicone rubber. Recent cancer research suggests nanotechnology may make breast implants safer as an alternative to silicone. Approximately 75 percent of post-mastectomy patients choose some form of breast reconstruction. While no medical device is free of risks, silicone breast implants still present a relatively high level of risk. This makes nanotechnology a promising alternative.

Similarly, nanotechnology may speed up recovery after breast reduction. Recovery from plastic surgery of any type has its risks. A University of Akron study suggests that nanotechnology produces additional properties that offer additional medical benefits patients cannot get from silicone or other traditional procedures. Some of the potential dangers of silicone materials include a greater instance of various forms of cancer, systemic diseases and psychological diseases. Dr. Judit E. Puskas, who led the study at the University of Akron, believes that nanostructured material may eliminate such risks and present a safer alternative to silicone-based breast implants.

Dr. Laura Kruper of the City of Hope Medical Center in Duarte, California is among doctors pointing out the psychological benefits of reconstruction following a mastectomy. While expense is a concern for some women, another factor is safety. This adds to the appeal of materials constructed using nanotechnology. The idea of using nanotechnology in breast implants is to alter the characteristics of the silicone. The manipulation would take place in the atoms of the silicone. Implants with the capability of delivering chemicals may speed up the recovery process and reduce side effects following surgery and initial treatment.

According to the Centers for Disease Control and Prevention, breast cancer is the most common cancer among women in the United States. It is the leading cause of death among women of all races. While breast cancer rates have been decreasing by about 2 percent since 2005, it is still estimated that 1 in 8 women will develop some form of breast cancer during their lifetime. This makes exploration of nanotechnology a worthwhile effort, according to Dr. Puskas and other doing similar research. The primary goal is to ensure that such technology is safe. Early research has shown promise. Some researchers have gone beyond Dr. Puskas’ early optimism and suggest that nanotechnology may result in materials that are not only safer, but materials that have the ability to deliver cancer medications more directly.

Nanostructured materials, by nature, are smaller. This includes smaller components within the material that minimizes complications. The new material will also have the ability to deliver certain cancer drugs more locally. The ability to deliver cancer drugs in this manner could help patients who have a breast reduction or have to have a mastectomy or double mastectomy due to breast cancer. Delivering cancer drugs this way could further minimize risks and side effects associated with chemotherapy. Right now, such technology is in the testing phase. The goal of nanotechnology research is to create alternatives to silicone implants that sharply reduce side effects and potential risks at the time of the implants and in the future. According to Breastcancer.org, there are about 3 million breast cancer survivors in the United States. A common concern among survivors, especially those who had some form of mastectomy or lumpectomy, is finding a way to restore the natural appearance of the breast.

Some women express a hesitation to get breast implants following breast cancer due to a fear that the implants themselves will cause additional medical problems. According to a study of breast cancer patients in California, fewer women are electing to have breast implants following mastectomy. On a nationwide level, however, statistics show that about 90 percent of women who have had a mastectomy following breast cancer choose some form of reconstruction. Nanotechnology is showing promise among all fields of science, but still must receive FDA approval to be used in breast implants. Early studies, however, are highlighting the potential of nanotechnology.

Do genes make a person Homosexual?

Posted: at 3:48 pm


This is the main question that is lurking the minds of biologists for quite some time now because many possibilities for the occurrence of a homosexuality gene exist. During the 1990s many researcher were studying the topic but by the end of the 20th century all such research work was slowed down as many people are shy when they are asked on topics related to sex and specially homosexuality. Scientists Sergey Gavrilets and William Rice have developed some guidelines for explaining the causes of homosexuality. During the past decade the scientists have discovered some patterns that might point to genetic causes of homosexuality. Among the discoveries the main finding was that in case of male homosexuality it seems to be inherited more from the mother than the father and the female maternal relatives of gay men have higher that average reproduction capacity. Another shocking discovery was that the chances of homosexuality increases in males with the number of older brothers he has even if the child has grown up away from his brothers. The reason for this is that the with each male fetus the mother develops an increased immunization to an antigen that is produced by male fetuses and this antigen plays an important role in masculinizing the brain. All the studies have strong evidences that homosexuality is caused by a gene but no research has pointed to any specific gene and the idea to which each research points is towards a polymorphic gene. Rice commented that, ‘We know that homosexuality (gay or lesbian) can be caused by simple genetic changes in fruit flies, and since so many reproductive and neurological genes are shared by flies and humans, it seems highly likely that there are major genes influencing homosexuality in humans, However, we also have firm evidence for a birth-order effect on male homosexuality, and discordance in the expression of homosexuality of identical twins, so clearly there is also an environmental influence on the trait.’ This research is the most guiding research on the topic, though it also has not pointed out any particular gene but this will be the backbone of all future researchers that can one day tell us the exact cause of Homosexuality.

Lubricin can play an important role in keeping joints agile

Posted: April 22, 2012 at 3:49 pm


Some relief for people having problems with their hip joints!! Duke University researchers have developed a method which enables specific measurement of biomechanical properties of hip joints in the case of mice. They have found out that lubricin which is a joint fluid has an important role to play in keeping joints agile. This has helped to come to a conclusion that treatments designed for increasing lubricin levels could aid in stopping the deterioration of arthritic joints. Tests conducted on mice showed that arthritic joints of mice lacked the gene which controlled production of lubricin showed greater friction as compared to joints of other animals and even at molecular level it demonstrated that joint cartilage of mutant animals appeared less stiff and rougher. This has suggested to the researchers that there can be a loss of cartilage mechanical integrity without requiring lubricin. Stefan Zauscher, Professor, Pratt School said: Lubricin has been considered important, but the experiments had not been done. This is the first look at the effects on biomechanics of lubricin’s presence or absence All this has opened a new window of hope for joint patients.

Eat your slice of beef without the contamination grief

Posted: April 15, 2012 at 3:48 pm


Consumers of canned beef and swine can now stay assured of the quality of the food and relish the taste without any fear of contamination courtesy ‘IdentiGEN’. IdentiGEN has developed TraceBack, the first-ever commercial DNA-fingerprinting technology for meat. The process starts at the farm or slaughterhouse, where animals are given are tested for pathogens. After receiving a clean bill of health, a worker takes a sample of the cow’s blood, meat or hair, analyzes it for genetic identifiers known as single-nucleotide polymorphisms, and stores the information in a central database. Before packaging is done at supermarket, the butchers take another DNA sample and checks it with the database to be sure of a 100% healthy packaged meat. And if there is trace of any errant pathogen found, the source can be traced back within hours thus making it possible for food-safety officials to nail down the source of the outbreak. According to Ronan Loftus, IdentiGEN’s director of business development: Each product has its own inherent label. It’s like nature’s bar code. Once this system is in place, you can pull a package of meat off the shelves and access its entire history. And the consumers have to pay a negligible premium to get 100% healthy meat.

New vaccine therapy to treat the deadly chemo-resistant ovarian cancer

Posted: at 3:48 pm


A better hope for thousands of women suffering from the ‘often resistant to chemotherapy’ ovarian cancer at its advanced stage. A new cancer vaccine therapy is on its way to launch expanding treatment options to such women. Thanks to the Cancer Treatment Centers of America. The vaccine is developed by AVAX Technologies, Inc. Dr. Edgar Staren, Chief Medical Officer of Cancer Treatment Centers of America said, Cancer Treatment Centers of America’s number one priority is to help our patients win the battle against cancer. This vaccine therapy represents a promising new chapter in the fight against this devastating disease and brings hope to women everywhere. Interestingly, this treatment method creates a patient-specific vaccine, using the patient’s own tumor tissues. The method also combines chemotherapy delivered directly into the abdominal cavity along with it. Dr. Staren said, To win the fight against cancer, it is absolutely vital we do everything we can to make innovative new treatments like this available to patients as soon as possible. It’s inconceivable that treatments like these – that give hope to patients – are often left on the laboratory bench, while cancer patients are told there is nothing more that can be done for them.

€3m to support skills development in biotechnology sector

The new joint venture

Recently, University College Dublin and Elan came out with a big news which is expected to mark a new beginning in the field of biotechnology. Both of these institutions will be working together on a venture. The highlight of this venture would be its cross linking policy between both the students of business studies and science branch in the university. The venture is expected to use the fusion of application of business studies and that of science including biology and applied engineering.

How will the venture work?

The venture is expected to run for at least seven years and will cost the company more than three million euros. The investment in the university’s new science center will help open two new scholarships (post doctoral ones). And that is not all. Another announcement has been made that lectures will now be organized annually, which will be targeted towards the students of the university, helping them to develop their intellectual abilities.

This groundbreaking initiative will not only be targeted towards the development of both biotechnology and the business associated with it but will also be acting as a juncture that will allow the students of science, business management and medical branch to work together under the common umbrella of Elan.

How will it affect the students?

The people in charge in both the organizations say that the venture will benefit the students at more than one level. On one hand, the venture will allow the students of different branch of studies to work together, and on the other hand, it will allow the students to work with the best in their respected fields. It will also allow the students to learn about the ever changing and risky world of bio technology. Although this is a giant leap for those involved, the success of the venture remains to be seen in time.

Biotechnology Industry on the Brink: Healthcare Reform and Agricultural

Posted: at 3:50 pm


Biotechnology industry expected to grow unceasingly

In spite of tremendous growth Biotechnology has shown in a short period, experts are of the opinion that all this growth witnessed so far is a tiny fragment of potential prospects of biotechnology. According to IBISWorld, $92 billion biotechnology is going to reach $146 billion by the year 2016.

Biotechnology: Unending source of new products

In spite of the fact that the industry is still in nascent stage, its products have already revolutionized medicine, agriculture and industries. Also, it must be remembered that there are hundreds of new products being developed in laboratories with promising results. When the market conditions were unfavorable, biotechnology start ups obtained funds from VC investments, which were eager to invest because of the high potential of the products being developed.

The companies also chose the route of mergers and acquisitions to leverage their core competencies and reduce costs in the period of unfavorable investor confidence during 2008 to 2010. Smaller companies merged with larger companies to get higher market shares and get access to resources. These developments have made biotechnology firms leaner and left them in better condition to proceed ahead with new efforts at research and development.

Another factor that is favoring the growth of biotechnology companies is the benefit of federal funding and support for biological defense projects. Pharmaceutical companies have acquired biotechnology firms in efforts to develop new formulations based on this revolutionary technology. Many companies are on the verge of breakthrough developments in developing drugs for conquering diseases like cancer and diabetes with the help of biotechnology.

Healthcare programs of federal government also support these companies to develop generic biological medicines and give them tax breaks. The role of biotechnology in improving the agriculture is evident; it offers solutions for increasing food production without degrading soil quality or posing threat to environment. The sustainable agriculture is clearly possible as shown by the new products and processes developed by biotechnology industry.

Conclusion:

With great promise of improved products in healthcare and agriculture, biotechnology is set to break its own record of tremendous growth seen so far!

Biotechnological applications boost Canada’s economic growth

Posted: at 3:50 pm


Biotechnology, as the term indicates, is the technical use of living organisms and biological processes for obtaining bio products. These products are used in the field of medicine, agriculture and industries. Biotechnology has been used in various day to day processes since time immemorial. From preparation of wine, cheese, curing of tea leaves to natural manures and jute processing, the knowledge of biology has been put to effective use in the various spheres of our lives. With the advent of modern biotechnology in the 1980s, this field has seen a great boom in its totality. The first major footprint of this modern era is believed to have begun when the American Supreme Court granted patent to Ananda Chakraborty for the genetically modified Pseudomona species capable of breaking down crude oil. Ever since it has spread its root wide in every possible field. Hence, now it is being considered as a bright prospect for the future industries.
The statistics
Recently, the reports of a study on the economic viability of biotechnology, conducted by the Centre for the study of Living Standards (a nonprofit Canadian organization aimed at economic research), was published. It was based on the figures provided by the Statistics Canada’s Biotech Use and Development Survey (BUDS). The research was headed by economist Ricardo de Avellez. The study showed great promise in the field with a forecast of $144 billion industry by 2030 at an average growth rate of 9.4%. Canada, being the world’s 10th largest economy, though generates only 1.19% of the total economy GDP from the biotechnology industry, it has seen phenomenal GDP growth at 10.7% between 1999-2007 preceded only by the mining and oil and gas extraction industry at 20.5%. This shows the rich economical implications that this field awaits in the mere future. In 2005 the number of innovative biotech firms increased from 358 in 1999 to 532, almost a 50% growth. Besides the impressive GDP, the employment that the industry has generated around itself is also a boon. Around 13,500 employees were employed in the various firms in 2005, a 74% increase from the figures in 1999. This figure definitely points to the immense potential of this yet to be explored field.
Biotechnology started in three different waves in three different time periods but now they overlap:
1. The Green Wave-Agricultural Biotechnology
This has been there right from the cradle of ancient civilizations. Nowadays with the development of genetically modified crops better yielding, pest resistant, seed less crops are being yielded. Only 20.1% firms and 9.8% of the work force are involved in the agricultural biotechnology and it generates 24.6% of the total revenue. Surely this field has a greater potential and would play an important role in meeting the food demands of the future.
2. The Red Wave-Medical Biotechnology
This field has seen the greatest growth. 58.3% of the biotech companies were involved in the health care system. A majority of 80.9% employees lent their workforce and it generated 70.6% of the revenue. The obvious reasons for its growth are the vaccines, artificial hormones, diagnostic tests, genetically tailored medicine and the list goes on.
3. The White Wave, the most recent Industrial Biotechnology
It is particular to term this a virgin field as its potential has been put to use the least whereas this is the field which shows the greatest promise. From development of biomining to bioremediation, from biofuels to biosensors, this field is teeming with unexplored industrial potentialities. With a small amount of industries into it, the field actually has seen a 10.1% decline in its revenues.
The bottomline
Biotechnology will definitely play a significant role in the country’s economy as more industries based on it will come up. Also the need for sustainable systems and cleaner and greener technology will provide impetus to this versatile field. Combined with the rich abundant natural resources, biotechnology will take the country a long way.
