Autistic children's abnormal metabolic profile findings
...ould directly or indirectly affect these metabolic pathways
and induce oxidative stress. Three (the catecho-O-methyltransferase gene, the transcobalamin II gene, and the glutathione-S-transferase M1 gene) were found to be significantly elevated in the autistic children. These genes are prevalent in the genera...
Technology helps Stanford shed new light on coronary bypass surgery
...new imaging system that lets doctors see the blood pathways
they have created while the patient's chest is still open. Until now, doctors were almost never able to confirm whether bypass surgery had been successful while the patient was still on the operating table. In most cases, only after the chest had bee...
Being too clean could be hazardous to your health and the environment

that can be envisioned, such as inhalation and skin exposure, when using antimicrobial soaps to wash dishes or when taking a shower. There is also risk of exposure when using triclosan laden moisturizers as they may also react with chlorine in the wa...
Measuring enzymes at end of cancer pathway predicts outcome of Tarceva, Taxol
...le enzymes are the end target of numerous cellular pathways
that are involved in cancer development and progression, the researchers say.Before these studies, no one has been able to accurately test the function of enzymes from a tumor sample, says Naoto Ueno, M.D., Ph.D., an associate professor in the Breast...

...se levels, which in turn affects other biochemical pathways
that accelerate diabetic complications such as cataracts. "Most people, scientists included, believe that green tea has more health benefits than black tea," says Joe Vinson, Ph.D., a chemist at the University of Scranton (Penn.) and lead author of t...
More evidence suggests statins help cut risk for advanced prostate cancer
...assembly. There are clues to suggest key cellular pathways
involved in cancer-risk reduction may include statins' effects on testosterone production, cell signaling, and inflammation. Or the drugs may play a role in changing prostate cancer cell membranes, which are rich in cholesterol. Prostate cancer is t...
Exercise slows development of Alzheimer's-like brain changes in mice, new study finds

related to DNA synthesis and DNA methylation, which are involved in carcinogenesis. Esther K. Wei, Sc.D., from Brigham and Women's Hospital and Harvard Medical School in Boston, and colleagues studied whether vitamin B6 measured as dietary intake and...
Three UCSD scholars elected to prestigious National Academy of Sciences
...s a leading world authority on signal transduction pathways
that regulate gene expression in response to extra cellular stimuli. His key achievements include definition of elements that mediate gene induction by hormones, cytokines and stress, identification and characterization of the transcription factors ...
Latest research and emerging treatments for osteoporosis focus of NYAS conference

through which new and old bones are repaired and remodeled. Clearer too are the basic biological properties of the skeleton and how it responds to hormonal, cytokine, and mechanical stimulation. How are these exciting new studies opening the doors ...
Human eggs can develop from ovarian surface cells in vitro
...capable of differentiating along two developmental pathways
and becoming either egg or granulosa cells. The authors speculate that this bipotent differentiation may represent a sophisticated mechanism created during the evolution of female reproduction, and not seen in ovaries of female prosimians (ancestral...
Treat depression and chronic pain separately, U-M researchers say
..."Our research provides further evidence that these pathways
are quite independent." While this study looked at fibromyalgia patients, it is possible that the results may apply to people who have other chronic pain conditions, such as low-back pain, irritable bowel syndrome and vulvodynia, the researchers say....
