Stress may increase cervical cancer risk

A woman’s daily stress can reduce her ability to fight off a common sexually transmitted disease and increase her risk of developing the cancer it can cause. – A woman’s daily stress can reduce her ability to fight off a common sexually transmitted disease and increase her risk of developing the cancer it can cause, according to a new study. No such association is seen, however, between past major life events, such as divorce or job loss, and the body’s response to the infection.

Zydus Cadila introduces Nudoxa cancer drug

Zydus Cadila has introduced Nudoxa for the treatment of various cancers. One of the critical drugs used in chemotherapy, Nudoxa heralds a new approach in cancer therapy. – Zydus Cadila has introduced an NDDS product ‘Nudoxa’ for the treatment of various cancers. One of the critical drugs used in chemotherapy, Nudoxa heralds a new approach in cancer therapy.

HIV persists in gut despite long term HIV therapy

Even with effective anti-HIV therapies, doctors still have not been able to eradicate the virus from infected individuals who are receiving such treatments, largely because of the persistence of HIV in hideouts known as viral reservoirs. – HIV virus is not usually eradicated from infected individuals even after long term HIV therapy because of the persistence of HIV in hideouts known as viral reservoirs. One important reservoir is the gut, where HIV causes much of its damage due to the large number of HIV target cells that reside there.

Update on Avian Influenza in West Bengal, India

No suspected human cases of Avian Influenza have been detected in any of the affected Districts. – No suspected human cases of Avian Influenza have been detected in any of the affected districts in West Bengal, in India. Number of affected districts (14 districts) remains the same. In these districts, 48 blocks and five municipalities are involved.

Scientists identify new cellular receptor for HIV

NIAID Scientists identified new cellular receptor for HIV, and it may help further elucidate the complex mechanisms of the pathogenesis of HIV infection. – A cellular protein that helps guide immune cells to the gut has been newly identified as a target of HIV when the virus begins its assault on the body’s immune system, according to researchers from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).

HIV can be transmitted through pre-chewed food

AIDS virus can be spread by a mother pre-chewing her infant’s food. – HIV can be transmitted to infants through food that is pre-chewed by an HIV-positive parent or caregiver, CDC researchers said Wednesday at the 15th Conference on Retroviruses and Opportunistic Infections in Boston, the New York Times reports. Specific findings from the study have not been released, the Times reports.

Tattooing improves DNA vaccine response

DNA-vaccination via tattooing induces stronger humoral and cellular immune responses than intramuscular delivery supported by molecular adjuvants. – Tattooing is a more effective way of delivering DNA vaccines; a tattoo can be more than just a fashion statement ? it has potential medical value, according to an article published in the online open access journal, Genetic Vaccines and Therapy.

DNA sequencing found virus killing transplant recipients in Australia

DNA sequencing establishes high throughput genetic sequencing as powerful tool for pathogen discovery; technology enables improvements in screening for transplant safety. – In the first application of high throughput DNA sequencing technology to investigate an infectious disease outbreak, link the discovery of a new arenavirus to the deaths of three transplant recipients who received organs from a single donor in Victoria, Australia in April 2007.

IGFBP7 protein may stop melanoma skin cancer

One might call it a tale of two melanocytes. Given the same genetic mutation, why does one melanocyte shut down growth and become a relatively benign mole, while another rages out of control and develops into deadly melanoma” – Howard Hughes Medical Institute (HHMI) researchers have uncovered a protein that stops the growth of melanoma, a cancer that develops from pigment-producing cells in the skin called melanocytes.

New hope for hepatitis C sufferers

Adelaide scientists will lead a $2 million five-year project to develop new vaccines and explore better treatment options for hepatitis C sufferers. – University of Adelaide virologists Dr Michael Beard and Dr Karla Helbig will work with colleagues from the University of NSW to develop new strategies to treat and prevent hepatitis C, which infects more than 170 million people around the world.

Occupational cancer risk in fruit and veg growers, hairdressers

New research by staff at the University’s Centre for Public Health Research show occupational cancer risk in fruit and veg growers, hairdressers and sewing machinists. – Increased risk of cancer for occupational groups including hairdressers, sewing machinists, field crop and fruit and vegetable growers, reported by New Zealand researchers. Occupational cancers account for 330 deaths in New Zealand each year, about five per cent.

Researchers cracking the code of bird flu time bomb

Australian scientists say they have found a safer way to study the bird flu virus, giving researchers a greater chance to solve the H5N1 strain. – Researchers at Griffith University Institute for Glycomics, Queensland led by Professor Mark von Itzstein have developed a technique to ‘crack-the-code’ of the deadly H5N1 avian influenza virus. It will enable influenza virus specialists and drug researchers to interrogate one of the virus’ key surface proteins without risk of infection.
