Protein prevents detrimental immune effects of bacterial sepsis

... allow the modeling of new therapeutics with lower side effects." The importance of this work is underscored by the fact that bacterial sepsis ranked among the top ten causes of death in both adults and neonates in 2002 in the United States (Natl Vital Stat Rep 2005, 53:1-89). The patients at greatest ri...

Bevacizumab Combined With Chemotherapy Improves Progression-Free Survival for Patients With Advanced Breast Cancer

Tendency to hair loss inherited from the mother

...ore take after their grandfather on their mother's side rather than their father. However, this defect is not simply caused by one gene: "We have indications that other genes are involved which are independent of the parents' sex," Prof. Nöthen stresses. The hereditary defect can therefore sometimes also ...

Gene therapy cures inherited liver disease in rats

...called, was manipulated so that it minimized toxic side effects. This disease involved a lack of a gene that is found in the part of the cell where detoxification occurs. It points the way to using gene therapy to cure and/or treat a host of other disease that occur because of the lack of genes in this ar...

Brain May Be Less Plastic Than Hoped

...g surgery can regain motor control on the affected side of their body and go on to develop normal language skills. But in adults, the case for brain plasticity has been less clear. A series of studies in the 1980s and 1990s seemed to show that, in adult animals, neurons “filled in?blank spots in the moto...

Discovery clarifies role of peptide in biological clock

Prescription Drug Patches Gaining Ground, Tackling New Therapies

...tion to improve patient compliance and reduce drug side effects, prescription skin patches are rapidly becoming an important healthcare product category. While quietly gaining market share for the treatment of chronic conditions such as angina, hypertension and HRT, the technology is set to make further i...

Chimp genome reveals a retroviral invasion

...ical copies of LTR sequences are created on either side of the retroviral element; the divergence of LTR sequences within a species can be used to estimate the age of an initial infection. Eichler and colleagues estimate that gorillas and chimps were infected about 3 -- 4 million years ago, and baboon and...

Six years of laboratory studies by Dr. Heller and his colleagues preceded the initial human trial begun earlier this year at Moffitt. The collaboration of USF an...

Pair of cancer genes found to drive both cell migration and division

...h outward - PI3K makes PIP3 on the membrane on one side of a cell while PTEN breaks it down on the other side. But when both enzymes are missing, levels of PIP3 remain constant throughout the membrane, and the cell can't migrate properly. In experiments with single-celled amoebae, Devreotes and his team ...
