What are the cost-effective implants in hip replacement surgery?
What are the cost-effective implants in hip replacement surgery?
New research led by the Hip Implant Prosthesis Study (HIPS) team at the University of Bristol Medical School has shown that small-head (less than 36 mm in diameter) cemented metal-on-plastic hip replacements are the most cost-effective in men and women older than 65 years. For adults younger than 65, small-head cemented ceramic-on-plastic hip replacements are more likely to be cost-effective.

Soil bacteria provide a promising E. coli treatment
E. coli , the notorious bug associated with severe food poisoning and usually caught from undercooked meat, is a common concern for anyone cooking over the festive period. While thoroughly cooking meat and washing vegetables and hands after food preparation can prevent E. coli infection, treatment for the severe stomach bug can be difficult, as antibiotics are known to make the disease worse by releasing a potent toxin into the infected person's gut.

Are scientists studying the wrong kind of mice?
Mice represent well over half of the non-human subjects of biomedical research, and the vast majority of those mice are inbred. Formed by generation after generation of mating between brothers and sisters, inbred mice are genetically identical to each other, like twins or clones. Inbreeding is well known to reduce health and vigor across species; this biological fact is the reason that incest is a universal taboo.

Genes tied to dementia in key early step toward new therapies
Genes tied to dementia in key early step toward new therapies
A UCLA-led research team has identified genetic processes involved in the neurodegeneration that occurs in dementia — an important step on the path toward developing therapies that could slow or halt the course of the disease. The findings appear today Medicine. The researchers discovered two major groups of genes involved in mutations that result in an overproduction of a protein called tau, a hallmark of the progressive loss of neurons seen in major forms of dementia.
