Cigarette Smoke Alters DNA in Sperm, Genetic Damage Could Pass to Offspring

...Ms6-hm and similar locations of non-coding DNA are sensitive to damage from radiation, mutagenic chemicals and intense industrial air particulate pollution. While the researchers did not specifically study the protein-coding regions of DNA where genes reside, Yauk notes that previous studies correlate mutation...

Reduced Oxygen to the Brain Increases Alzheimers Risk in Stroke Victims

...ating two key signalling molecules, which are very sensitive to fluctuations in oxygen levels. The scientists suspect that in low oxygen conditions these molecules could begin the increased production of a toxic protein called amyloid which builds up in the brains of people with Alzheimers....

Stem Cell Therapy Could Provide Cure for AMD in Five Years

...photoreceptors) in the retina, which are the light sensitive cells, depend for their survival on the normal functioning of these cells, and so failure of these cells leads to progressive loss of vision. In addition, the disease often provokes a scarring process at the back of the eye leading to the formatio...

Effects of 'starvation Hormone'-Newly Identified in Low-carb Diets

... reduce their physical activity and made them more sensitive to entering torpor, a short-term, hibernation-like state. 'During fasting, the liver hormone communicates with adipose tissue to send fat to the liver. It turns on the metabolism of fat into ketone bodiesand at the same time, it sensitizes the anim...

Menthol Receptor-A Thermosensitivity Determinant in Cold Temperature

... Also, mice engineered without TRPM8 are much less sensitive to cold than mice with TRPM8. TRPM8 does not seem to be the sole receptor responsible for detecting cold, Jordt said. The TRPM8 knockout mice sensed temperatures below 15 C degrees, which indicates the possible existence of another pathway for dete...

Should Genetic Information Be Disclosed to Insurers?

...l. It is not inherently more specific, predictive, sensitive or private than other kinds of health information. Professor Holm concedes there are worries about sharing genetic information - allowing insurers to see genetic information could deter people from getting tested or insurers may use the information...

Radical Idea of Implanting Tiny Electrodes to the Deaf

...veloped earlier at U-M. The scientists found their sensitive 16-electrode microarray resulted in several advantages over cochlear implants. Approved by the Food and Drug Administration in 1984, cochlear implants have greatly benefited profoundly and severely deaf people. More than 100,000 implants have been ...

Combination of Brain Scans, Reading Skill Tests can Predict Kids Reading Problems

...honological awareness and to make these tests more sensitive to differences among children, the researchers analysed the images using a method called voxel-based morphometry that uses the density of the brains white and grey matter to zero in on activation patterns in specific parts of key brain regions. The...

Ancient Healing Technique Gains New Popularity in Iraq

...uous bleeding is ruled out, furthermore it is less sensitive than other areas," Hajam explained. "Prophet Mohammed himself used hijama. It is for many diseases, from headache to arthritis and sciatica, even for sterility for men and women," he added. The technique was also traditionally used by the historic...

Hormone Therapy An Alternative to Chemotherapy for Ovarian Cancer

...eve that in those ovarian cancers which are highly sensitive to oestrogen, this blocking mechanism could slow the growth and spread of disease. The study was funded by Cancer Research UK and involved 44 women with high oestrogen receptor (ER) levels, whose cancer had relapsed after surgery and chemotherapy. ...

When parents noticed boils peeping out of the plaster, they took the child to the hospital Jan 21. The report quoted Ram Babu as saying that senior do...

HIV Drug Resistance can Be Identified by Genome Sequencing

"So if there should be a problem with mobiles, then it may be a bigger problem for children. "Since we advise that children should be discouraged from using mobile phones, we...

New Mechanism Identified for Resistance to Targeted Lung Cancer Drugs

...th factor, a process that fuels tumor growth, were sensitive to treatment with these drugs. Although tumors that respond to EGFR inhibitors do so rapidly and dramatically, eventually the tumors become resistant and resume growing. About half the time, a secondary mutation that interferes with the drugs' bind...

Lifestyle changes not prescription drugs to fight diabetes, say scientists

...ghout the body and causes the cells to become more sensitive (more responsive) to insulin and remove more glucose from the blood. Professor Montori and his colleagues, argue in the BMJ: 'If clinicians offer patients glitazones to prevent diabetes, they are offering certain inconvenience, cost, and risk for l...

Virtual Colonoscopy is Most-effective for Screening Colon Cancer

...ew methods have demonstrated that the test is very sensitive for CRC and could be an effective screening option for patients. Previous cost-benefit analysis studies comparing OC and CTC (with OC referral for all polyps of any size) have estimated that OC is more cost effective. However, these studies ignore ...
