High resolution 'snapshots' detail dynamics of a cocaine antibody

...cing improvements in the immune system in weeks or months that previously took billions of years. "The structural insights into antibody catalysis that we have shown with 7A1 Fab' are critical for any future improvement of effective biocatalysts," Zhu said.

Intensive statin therapy may partially reverse plaque build-up in arteries

...ogression was assessed at baseline and after at 24 months of treatment. "Previous similar studies with statins have shown slowing of coronary disease, but not regression. This regimen significantly lowered bad cholesterol, and surprisingly, markedly increased good cholesterol levels," said Steven Nissen,...

Molecular mechanism may explain how fevers spark seizures

...hildren worldwide, generally between the ages of 6 months and 6 years. Most children will suffer no long-term consequences from the convulsions, which tend to be generalized -- involving the whole body -- but some will go on to develop epilepsy.

Scientists force viruses to evolve as better delivery vehicles for gene therapy

...ions of accelerated evolution, requiring about two months of lab work, they succeeded. Schaffer and his team at UC Berkeley and at Ohio State University report their success in the current issue of Nature Biotechnology.

For the first time: Longevity modulated without disrupting life-sustaining function

...bernation-like stage in which they can hang on for months but don't reproduce. Unless Smk-1 is missing, that is. Without Smk-1 to provide guiding assistance, DAF-16 is unable to slow down the aging process, and the worms die young. "These mutants are shorter lived because they are unable to respond appro...

Resveratrol prolongs lifespan and delays onset of aging-related traits in a short-lived vertebrate

...fish species with a captive lifespan of only three months was described by Cellerino and colleagues. In the new work, the researchers used this short-lived fish to test the effects of resveratrol on aging-related physiological decay. The researchers added resveratrol to daily fish food and found that this t...

Faults in newly discovered breast stem cells may lead to tumours

...ory itself ?a breast cancer stem cell ?may survive months or years later. In the context of international breast cancer research, the discovery of the breast stem cell is quite profound and will most likely form the basis of research in the area for years to come. The ultimate objective is to create a d...
