#Tata doctors find way to cut oral cancer risk Tata Memorial Hospital, the cancer hub in Parel, announced a breakthrough on Tuesday that could
not only reduce the risk of death for oral cancer patients by 36 %but also prevent recurrence of the disease by 55%.
%The innovation is an'extra cut'-a dissection in medical parlance-along the neck to detect
if the patient's cancer had spread from his/her oral cavity to the neck. The cut would be a prophylaxis-a preventive medicine-against aggressive cancer forms
and prevent the need for chemotherapy or radiation. The findings were announced by Tata Memorial Centre's Dr Anil D'Cruz at an ongoing meeting of American Society of Clinical Oncology at Chicago on May 31.
The findings were published also in the latest edition of New england Journal of Medicine. The study assumes significance
because India carries the highest burden of oral cancer in the world, with around 1 lakh new patients detected every year.
It is the most common cancer among Indian men and third most common among Indian women.
Worse, almost half of them die within 12 months of diagnosis, because of the delay in seeking treatment.
At a press conference held in the Parel hospital on Tuesday, one of the other investigators Dr Pankaj Chaturvedi said,
"When a patient comes with a lesion in his oral cavity, be it his her tongue
or jaw bone, it's not possible to say whether the cancer has progressed beyond to the neck region.
This is especially in the early stages of oral cancer.''''At present, patients may choose to not undergo neck dissection and wait until some cancerous bulge-basically,
a recurrence-appears in his/her neck. It has been one of medicine's long standing ethical debate on
whether or not early stage oral cancer patients should undergo a neck dissection. On one hand, the dissection is a delicate operation
because the cut is made near important nerves (for facial expression and spine), veins and arteries running along the neck.
On the other hand, if patients choose to not undergo a neck dissection, they may be at the risk of not diagnosing the cancer's complete spread early enough.
This could impact their quality of life and more importantly, their survival.""But this research has put an end to this debate.
A neck detection can save more lives. All it requires is 30 minutes extra on the operation table,''added Dr Chaturvedi.

The method, called Virscan, developed by Howard Hughes Medical Institute (HHMI) researchers can test for current and past infections with any known human virus,
including HIV and hepatitis C. The method, called Virscan, is an efficient alternative to existing diagnostics that test for specific viruses one at a time.
Stephen Elledge, an HHMI investigator at Brigham and Women's hospital and his colleagues have used already Virscan to screen the blood of 569 people in the US, South africa, Thailand, and Peru.
Virscan works by screening the blood for antibodies against any of the 206 species of viruses known to infect humans.
The immune system ramps up production of pathogen-specific antibodies when it encounters a virus for the first time
and it can continue to produce those antibodies for years or decades after it clears an infection.
PTI That means Virscan not only identifies viral infections that the immune system is actively fighting, but also provides a history of an individual's past infections.
To develop the new test, Elledge and his colleagues synthesised more than 93,000 short pieces of DNA encoding different segments of viral proteins.
They introduced those pieces of DNA into bacteria-infecting viruses called bacteriophage. Each bacteriophage manufactured one of the protein segments-known as a peptide
Antiviral antibodies in the blood find and bind to their target epitopes within the displayed peptides.
The scientists then retrieve the antibodies and wash away everything except for the few bacteriophage that cling to them.
they can identify which viral protein pieces were grabbed onto by antibodies in the blood sample. That tells the scientists which viruses a person's immune system has encountered previously
either through infection or through vaccination. The study was published in the journal Science e

#Copper and its alloys destroy'stomach flu'virus Metal surfaces containing copper can destroy human norovirus, one of the causes of gastroenteritis or'stomach flu,
including copious vomiting and diarrhea. It is a major problem on cruise ships, in restaurants, and in elder care homes, where the disease is transmitted easily by environmental contamination,
"said Clyde Manuel, a doctoral student of North carolina State university, Raleigh.""This is the first study to demonstrate copper's destructive powers against human norovirus,
Several earlier studies have established that copper is very effective against a host of bacteria that cause a variety of human diseases including stomach ailments, pneumonia,
meningitis, skin infections etc. But this is the first study to record copper's action against a virus. In the study,
He notes that a hospital intensive care unit that recently replaced other materials in high touch surfaces with copper reduced the overall infection rate by half.
#New sensor to detect cancer, HIV, hepatitis Researchers have developed a highly sensitive nanomechanical sensor that can detect cancerous tumours as well as viral disease markers for HIV,
hepatitis and herpes. Researchers from Moscow Institute of Physics and Technology (MIPT) developed the ultracompact nanomechanical sensor for analysing the chemical composition of substances and detecting biological objects.
The sensor can detect viral disease markers, which appear when the immune system responds to incurable
or hard-to-cure diseases, including HIV, hepatitis, herpes, and many others. The sensor will also enable doctors to identify tumour markers,
whose presence in the body signals the emergence and growth of cancerous tumours. The highly sensitive sensor will allow for diagnosing diseases long before they can be detected by any other method,
which will pave the way for a new-generation of diagnostics, researchers said. Calculations done by the researchers,
Dmitry Fedyanin and Yury Stebunov, showed that the new sensor will combine high sensitivity with a comparative ease of production
and miniature dimensions, allowing it to be used in all portable devices, such as smartphones, wearable electronics, etc.

Cure for untreatable wounds BEIJING: Chinese scientists have claimed successfully growing muscle stem cells in a test tube,
a breakthrough that could potentially save the careers of top athletes besides cure untreatable injuries caused from accidents and surgeries due to cancer."
"It can generate enough stem cells to heal permanent wounds, especially those caused externally,"said Hu Ping, a cell biologist with the Shanghai Institute for Biological science at the Chinese Academy of Sciences."
"Muscle stem cells are the ultimate way to cure muscle-related wounds or diseases, "Hu said,
but also address a wide range of medical issues such as treatments for people involved in car accidents,
those who have had surgery for cancer, or sufferers of amyotrophic lateral sclerosis (ALS).""This technology could cure (recently retired Chinese hurdler) Liu Xiang's injury,
"Hu said, referring to Asia's first Olympic gold medallist in the 110-metre hurdles at the 2004 Athens Olympics who also ranks as the continent's first world champion hurdler.
A nagging tendon injury caused the Shanghai native to limp off the track when Beijing hosted the Summer Games in 2008.
blaming his longstanding injury. Now scientists from his hometown believe they have found a way to restore him to full health,
along with millions of other patients bearing muscle-related injuries. By transplanting the stem cells from the test tube back into the patient's body
large wounds require large numbers to be dragged over from healthy parts of the patient's body,
adding that no cure was available-until now. The professor said a similar method could be used to grow tendon stem cells to treat injuries like Liu's. She added that
although tests on mice showed that the test tube-generated cells were almost identical to the natural cells,
The team has contacted hospitals in China about conducting human trials but has struggled to find volunteers,
"Most people in China don't care about muscle injuries until they find they cannot walk,
#Microsoft's drones to catch mosquitoes and help stop epidemics WASHINGTON: Microsoft researchers are developing autonomous drones that collect mosquitoes to look for early signs that potentially harmful viruses are spreading,
with the goal of preventing disease outbreaks in humans. Project Premonition, launched by American tech company Microsoft,

or avian flu before it occurs, whether or not it is a disease spread by mosquitoes,
researchers said. It will do that by relying on what Ethan Jackson the Microsoft researcher who is spearheading the project,
