A new recovery for heart attacks

...degraded. The other domain of HIF was known to be responsible for the actual activation of genes that helped cells adapt to low oxygen, however the molecular switch for that has to date been unknown.Dr Whitelaw and colleagues found under low-oxygen levels, HIF loses a hydroxyl molecule from an asparagine amino ...

Honey curbs bacteria in the oral cavity

...rresting the dental plaque bacteria believed to be responsible for dental caries, a New Zealand researcher will report at the American Association// for Dental Research annual meeting this month. An enzyme in honey that produces hydrogen peroxide is the key to the antimicrobial activity of honey, according to D...

Periodontal disease may amass the risk of developing Type 2 diabetes

... the researchers said. "In the pancreas, the cells responsible for insulin production can be damaged or destroyed by high levels of cytokines," said Dr. Anthony Iacopino from the Marquette University School of Dentistry. "Once this happens, it may induce Type 2 diabetes, even in otherwise healthy individuals wit...

A question on study of Adult Stem Cell

...ng that fused cells happen often, or that they are responsible for the findings of others in which adult stem cells seemed to show multipotency," Lander told UPI. "If indeed that's the only way such adult stem cells become multipotent, then one would indeed have to be concerned that such cells are clearly not 'n...

Genetic innovation

...h sexes. Oestrogen influences height because it is responsible for bones fusing over at the ends, which stops people growing. A person's height depends on both genetic and environmental influences. Previous studies have identified the aromatase gene and the Y chromosome gene as height genes in men who are very...

Breast cancer risk seen in twins

... Hence a combination of genes is more likely to be responsible for many diseases....

Transforming stem cells to lung cells

...system which caused them to develop into the cells responsible for gas exchange in the lungs. This is the first step towards replacing damaged lung tissue with healthy functioning cells. These could be developed so that the body would not reject them and could, in time, replace conventional lung transplants. The...

Mutating viruses helps produce antibodies

...acterial family known as Bordatella. The germs are responsible for very contagious and potentially lethal respiratory diseases such as whooping cough. Bordatella is afflicted by a plague of its own, a kind of virus known as a bacteriophage or "bacteria eater." This phage infects Bordatella using its tail-like st...

Dietary cure for fighting Helicobacter pylori

....// It's now well established that this microbe is responsible for ulcers and even stomach cancer. Clearing it with antibiotics is an important form of treatment in gastrointestinal problems. Now researchers at Hopkins Medical School found that sulforaphane, a compound found in broccoli and broccoli sprouts, ...

Birth weight may be influenced by genes

...tance that surrounds the nucleus in each cell--was responsible for about 11% of the variability in birth weight among the study animals. According to a report, this is the first time that researchers have been able to demonstrate a link between cytoplasmic DNA and birth weight. The results suggest that a mother'...

Gene therapy restores sight

...ent.// The disease involves a defect in the genes responsible for the retina's ability to translate light into nerve impulses. In humans, LCA causes severe rapid onset of blindness, a process which begins before birth so infants are born partially blind. Bennett's team injected the eyeballs of dogs born with L...

Increase in renal problems

...entists were able to lower the levels of molecules responsible for the oxidative stress. “This study shows how free radicals and nitric oxide interact to produce oxidative stress and help cause these neurological dysfunctions,” said Dr Nick Vaziri, head of the research. “It also may provide a way to treat these ...

A new genetic label for stroke

...icine observed at two possible mutations on a gene responsible for producing paraoxonasc, or PON1, an enzyme that helps HDL cholesterol prevent the oxidation of LDL cholesterol. This process plays a major role in the development of heart and blood vessel disease leading to stroke. Blood samples of 120 people wh...

Nightlights could ward diabetic blindness

...ired and this has an impact on the rods (the cells responsible for night vision) which have a high demand for oxygen. Researchers at the University of Cardiff, have found that night time illumination can reduce the rods' demand for oxygen. The work was done with seven patients with type 2 diabetes and eight he...

Heart attack risk starts at 20

...he focus back to early adulthood when you become a responsible person for your own health," Stein said. The guidelines also try to point out that "it's not just one thing, it's a combination of things" that culminate to cause heart disease. Other recommendations to prevent heart attack and stroke include mainta...

Risk Factors for vision problems in Diabetes

...e with diabetes. In the United States, diabetes is responsible for 7 percent of legal blindness, making it the leading cause of new cases of blindness in adults 22 to 70 years old. Researchers from the Texas studied more than 600 individuals who were part of the Hoorn Study, a population-based study consisting ...

Gene treatment for macular degeneration

...eneration. Researchers have recognized the gene responsible for some cases of macular degeneration quite recently. With this knowledge, and the advances in gene therapy, they are able to get the abnormal gene working again. The trick is that the virus is used to target the bad gene. The virus carries with it ...

Jumping genes eliminate sections of DNA

... DNA as we evolved.Altogether, L1 elements "may be responsible for creating about 27 percent of our DNA and perhaps more," Moran said. "So these have been significant players in evolution and shaping the human genome."...

Awareness of oral cancer is low

...hat tobacco is a risk factor for oral cancer (it's responsible for 80 per cent of all oral and throat cancers), but only 20 per cent knew that heavy alcohol use is also a contributing influence. Excessive sunlight may increase the risk of lip cancer - and 25 per cent of the group knew this. Researchers feel th...

Hazards of anger in heart patients

...in good health, physical over-activity can also be responsible for adding strain to an already weak heart, thereby provoking for an abnormal behaviour.Such patients with cardiac diseases may have to take up exercises provoking for an abnormal behaviour.Such patients with cardiac diseases may have to take up exer...
