New compound 'highly efficacious' at reducing human tumour growth
...n-dependent kinase (CDK) control has been directly linked
to the molecular pathology of cancer. CDK's are a family of enzymes required for the correct timing and order of events in the cell division cycle. Vascular endothelial growth factor (VEGF) / VEGF-receptor tyrosine kinase (VEGF-RTK) and platelet-deri...

to fertility medications utilized to induce superovulation, or the progesterone employed to help implantation; in vitro culture conditions which could be related to the length of the culture or the concentrations of certain media components such as s...
In the obese, metabolic adaptations post-weight loss lead to regaining of shed pounds
...definitive conclusions in between these studies is linked
to the way metabolic mass is estimated, the selection of research subjects, and the methods of weight loss and weight maintenance. Human studies are impractical, because there is no way to identify individuals predisposed to the development of obesi...
Underground carbon dioxide storage reduces emissions

to global warming, and there has been a worldwide effort to reduce those emissions and their effects on the planet--the Kyoto Protocol, for example, has mandated these changes. Carbon dioxide sequestration is being evaluated internationally as a via...
Melting ice cap gives urgency to new census of marine life project in Arctic Ocean

to inflammation and immune responses. This is evidence that pathological events may be occurring in the aging brain, possibly related to gene damage. The researchers then went on to show that many of the genes with altered expression in the...
LARGE protein can overcome defects in some types of muscular dystrophy
