TRANSPLANTATION: How to identify liver transplant recipients who no longer need drugs A very small number of individuals who have had a liver transplant are able to stop taking drugs that prevent the immune system from attacking their transplanted liver (immunosuppressants). These people are said to be tolerant of their new liver, and becoming independent of immunosuppressants revolutionizes their life, as long-term use of immunosuppressants has serious side-effects.
Stanford Worm Study Challenges Prevailing Theory Of Aging
Age may not be rust after all. Specific genetic instructions drive aging in worms, report researchers at the Stanford University School of Medicine. Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage akin to rust, and implies science might eventually halt or even reverse the ravages of age. "We were really surprised," said Stuart Kim, PhD, professor of developmental biology and of genetics, who is the senior author of the research.
UC Santa Barbara Chemist Goes Nano With CoQ10
If Bruce Lipshutz has his way, you may soon be buying bottles of water brimming with the life-sustaining coenzyme CoQ10 at your local Costco. Lipshutz, a professor of chemistry at UC Santa Barbara, is the principal author of an upcoming review, "Transition Metal Catalyzed Cross-Couplings Going Green: in Water at Room Temperature," which will be published in Aldrichimica Acta in September.
Key Mechanism Of Cellular Damage In Aging And Disease Unravelled
Damage can be measured by newly captured events in cell's powerhouse Researchers have taken a first snapshot of how a class of highly reactive molecules inflicts cellular damage as part of aging, heart disease, stroke, cancer, diabetes, kidney disease and Alzheimer's disease to name a few.
Genes Evolve To Minimize Protein Production Errors
Scientists at Harvard University and the University of Texas at Austin have found that genetic evolution is strongly shaped by genes' efforts to prevent or tolerate errors in protein production. Their study also suggests that the cost of errors in protein production may lie in the malformed proteins themselves, rather than the loss of functional proteins. Misfolded proteins can build up in long-lived cells, like neurons, and cause neurodegenerative diseases.

CAS Scientists Help To Explain Diversity of Molecular Structures
By studying the variety of chemical substances and their structures recorded in the CAS REGISTRY database, CAS scientists have discovered that a limited number of molecular shapes are the frameworks for a disproportionately large percentage of reported substances. The analysis, published in The Journal of Organic Chemistry, explains why certain molecular frameworks are more likely to be used in new compounds and may also help identify new regions of chemistry space ripe for exploration.
