Childhood environment influences reproductive function
.... The Bangladeshis who took part in the study were middle class women from the Sylhet District. Although a relatively affluent area of the country, inhabitants still suffer from higher immune challenges, primarily due to poor sanitation and limited access to healthcare. These aspects of the environment in B...Protein interactions targets for Huntington disease therapy
..., that person will develop the disease usually in middle age. Children born to parents who go on to develop Huntingtons disease have a 50:50 chance of having the disease themselves. Musician Woody Guthrie was among its best known sufferers. Many of the proteins that interact with Huntingtons are modulat...The opossum genome sequence casts light on evolution, immunity and disease
... matters," says Goodstadt. "Genes that lie in the middle of chromosomes are less likely to be shuffled before being passed on to the next generation. So evolution has been pretty good at getting rid of mutations when they're near the ends of chromosomes, but rather poor at doing so in their middles."

Each mature ciliated cell has up to 200 cilia, which have to co-ordinate their movements to orient their effective stroke in the same direction as their cellmates and all the cilia on...Study links faulty DNA repair to Huntington's disease onset
...ingtons disease symptoms usually dont appear until middle age, leading scientists to wonder what triggers the disease onset and whether it can be haltedor at least slowed down.

In 2003, 5.1 million Indians had HIV/AIDS, over 3 million had tuberculosis and 1.8 million had malaria. Approximately 32 million Indians were diabetic in 2000, a number expected to reach 80 million by 2030. ...Slow but sure -- Burned forest lands regenerate naturally

On low and middle elevation sites, there were actually more conifers where there was more shrub and hardwood cover - what favored one group also seemed to favor the other. At higher elevations, shrub cover was less of an issue and the abundance of conifer regeneration...... nail is made up of three distinct layers with the middle layer protecting the delicate bottom layer from breaking towards the quick.
