Area where HIV persists in spite of treatment identified

Area where HIV persists in spite of treatment identifiedWashington, Jan. 13 - Researchers may have found the answer to the question as to how the HIV virus persists in the body, and replication resumes if treatment is interrupted.

They recently discovered T memory stem cells, which could be long-term viral reservoir, and may be potential targets for future treatment of HIV.

Gene defect prior to birth linked to onset of childhood leukemia

genesWashington, Jan. 13 : A team of researchers has discovered a genetic signature that implicates a key mechanism in the immune system as a driving force for a type of childhood leukaemia.

A key factor driving the leukaemia for one in four ALL patients is a mutation that causes two of their genes, ETV6 and RUNX1, to fuse together. This genomic alteration happens before birth and kick starts the disease.

Non-coding DNA key contributor to type 2 diabetes

type 2 diabetesWashington, Jan. 13 : A new study has revealed that variations in non-coding sections of the genome might be important contributors to type 2 diabetes risk.

DNA sequences that don't encode proteins were once dismissed as "junk DNA", but scientists are increasingly discovering that some regions are important for controlling which genes are switched on.

Tweaking MRI method may help spot heart problems earlier

Tweaking MRI method may help spot heart problems earlierWashington, Jan. 13 - Researchers including an Indian origin scientist have suggested that a new MRI method to map creatine at higher resolutions in the heart may help clinicians and scientists find abnormalities and disorders earlier than traditional diagnostic methods.

Telescope eye implant restores age-related macular degeneration sufferers' eyesight

age related macularWashington, Jan. 13 : Researchers are restoring the vision of people suffering from age-related macular degeneration (AMD) by implanting tiny telescopes in their eyes.

Dr. Sid Mandelbaum, an ophthalmologist at East Side Eye Surgeons in New York City, told Fox News that a tiny telescope, which is implanted in the eye after the lens is removed, takes the place of the individual's own lens and remains in the eye permanently.

Focused ultrasound can boost brain's sensory performance

Focused ultrasoundWashington, Jan. 13 : It is a well known fact that whales, bats, and even praying mantises use ultrasound as a sensory guidance system, and now a new study has found that ultrasound can modulate brain activity to heighten sensory perception in humans.

Scientists at Virginia Tech Carilion Research Institute have demonstrated that ultrasound directed to a specific region of the brain can boost performance in sensory discrimination.

Artificial bone marrow development brings leukemia treatment closer to reality

Artificial boneWashington, Jan. 11 - Researchers have developed a prototype of artificial bone marrow that may be used to reproduce hematopoietic stem cells.

The porous structure developed by the scientists of KIT, the Max Planck Institute for Intelligent Systems, Stuttgart, and Tubingen University, possesses essential properties of natural bone marrow and can be used for the reproduction of stem cells at the laboratory.

This might facilitate the treatment of leukemia in a few years.

Hot tubs and spas linked to winter disease outbreaks

Hot tubs and spas linked to winter disease outbreaksWashington, Jan 11 - A new study suggests that disease outbreaks tied to swimming happen even in the winter, and that occurs often after people go in hot tubs or spas.

Between 2009 and 2010, there were 81 outbreaks and 1,326 cases of illness in the United States linked to recreational water exposure (in pools, lakes, hot tubs, etc.), according to information reported from 28 states and Puerto Rico.

Low doses of common anticancer drugs can protect against diabetes

anticancer drugsWashington, Jan. 10 - A new study has shown that very low doses of a cancer drug protect the insulin-producing cells in the pancreas and prevent the development of diabetes mellitus type 1 in mice.

Researchers from the Faculty of Health and Medical Sciences at the University of Copenhagen also found that at the same time, the medicine protects the insulin-producing cells from being destroyed.

Men in no danger of becoming extinct!

Y chromosomeWashington, Jan. 10 : Researchers have dispelled the common notion that the Y's genes are mostly unimportant and that the chromosome is destined to dwindle and disappear, after comparing Y chromosomes in eight African and eight European men.

Moderate coffee consumption 'not linked' to dehydration

Moderate coffeeWashington, Jan. 10 : Researchers have dispelled the myth that coffee consumption can cause dehydration, as they have found that drinking moderate amounts of coffee does not result in dehydration and contributes to daily fluid requirements in regular coffee drinkers just as other fluids do.

New breakthrough brings malaria drugs closer to reality

malaria drugsWashington, Jan. 10 : An Indian origin researcher has found that a form of malaria, which is common in India, Southeast Asia and South America, attacks human red blood cells by clamping down on the cells with a pair of proteins.

New study by researchers at Washington University School of Medicine in St. Louis provides details that will help scientists design better vaccines and drug treatments for the strain, Plasmodium vivax.

New toxin can kill lurking HIV-infected cells

HIV infected SellsWashington, Jan. 10 : A team of researchers has demonstrated in a mouse model that an HIV-specific poison can kill cells in which the virus is actively reproducing despite antiretroviral therapy.

According to the researchers from University of North Carolina and NIH, such a targeted poison could complement antiretroviral therapy, which dramatically reduces the replication of HIV in infected cells but does not eliminate them.

Scientists decode elephant shark genome

Washington, Jan. 9 : A team of researchers has sequenced the genome of the elephant shark, a curious-looking fish with a snout resembling the end of an elephant's trunk.

The elephant shark and its cousins the sharks, rays, skates and chimaeras are the world's oldest-living jawed vertebrates. But their skeletons are made of cartilage rather than bone, making this group of vertebrates an oddity on the evolutionary tree.
