Protein overexpression at heart of heart failure

...he L-VDCC, based on gene expression changes, is an early step in a cascade ultimately induced in heart failure. This provides a rational framework for novel therapeutic intervention in heart failure. ...

Elucidation of the genome for diabetics with DNA chips

...T2. Abnormalities in insulin secretion appear very early in the children of diabetic parents. These individuals become hyperglycaemic when they put on weight and are resistant to the insulin they produce. The team of Philippe Froguel was the first to identify a gene associated with DT2 ?that encoding gluco...

Massey researchers induce cell death in leukemia

Researchers urge monitoring of bone health during chemotherapy

...ffect on bone metastasis in the experimental mice, early clinical trials in humans using G-CSF with chemotherapy have so far shown no adverse effects on survival and no increase in bone metastasis. In fact, breast-cancer patients undergoing dose-dense chemotherapy with G-CSF support tend to have a longer d...

Post oak grasshoppers emerging

...grasshoppers become adults in late April, and from early May to mid-June the females lay their eggs in the soil. A female typically lays five to six eggs at a time in a pod, and will produce two to four pods over her lifetime. In the spring, when post oak leaves begin to emerge, the eggs hatch and the nymp...

Selective marker found to indicate aggressive form of breast cancer

...g breast cancers, this subtype is known to have an early age of onset and a very short time between treatment and relapse. It is more commonly detected during normal screening mammogram intervals than other screening subtypes, which likely reflects its aggressive nature. These important clinical correlati...

Genes may determine success of hip replacement surgery

Among those with symptoms, 91 had early signs of “aseptic loosening,?which describes a condition in which the artificial joint comes loose and the surrounding bone begins to dissolve. The other 71 patients had deep-seated infection, which occurs when the body is unable to control infection...

Scientists find new genetic clue to cause of Alzheimer's disease

...dentified three genes, variants of which can cause early onset Alzheimer's, and one that increases risk for the late onset form. This discovery provides a completely new genetic clue about the late onset forms of this very complex disease. We are eager to investigate the role of this gene further." Scien...

Global 'sunscreen' has likely thinned, report NASA scientists

Branches from the trees would have fallen to the floor and decayed, providing a new food chain for the bugs living below. "This was also a significant moment in the history of the planet.
