Plastics Chemical Retards Growth, Function Of Adult Reproductive Cells
Bisphenol A, a chemical widely used in plastics and known to cause reproductive problems in the offspring of pregnant mice exposed to it, also has been found to retard the growth of follicles of adult mice and hinder their production of steroid hormones, researchers report.

Study Finds Noninvasive Blood Test For Liver Fibrosis May Alleviate Need For Liver Biopsies For Some Patients With Chronic Hepatitis C
A study in the June issue of Clinical Gastroenterology and Hepatology, published by Elsevier, demonstrates that the Hepascore(TM) liver fibrosis blood-serum test panel may help physicians more accurately diagnose and stage liver fibrosis in patients with chronic hepatitis C (HCV), potentially alleviating the need for liver biopsy, the standard of care for staging fibrosis, in a particular subset of patients. The Hepascore test panel is provided exclusively by Quest Diagnostics Incorporated (NYSE: DGX), the world"s leading provider of diagnostic testing, information and services.

The Importance Of Preventing Congestion In Heart Failure

Preventing vascular congestion is an important mediator in heart failure, reports a study in the June issue of the Journal of Cardiac Failure, published by Elsevier. The authors previously demonstrated that venous endothelium is a key regulator of central blood volume, organ perfusion and hemostasis in heart failure (HF). The present study demonstrates that in venous endothelium, inflammatory/oxidative and hemostatic programs were significantly activated in HF dogs compared to normal dogs. In normal dogs, fluid loading significantly activated these same programs to levels that approached those seen in dogs with HF. These findings suggest that biomechanical stress (i.e. vascular stretch) may be an important mediator of these endothelial responses, and highlight the importance of preventing congestion. Further investigation is needed to clarify whether the venous endothelial phenotype in unique individuals may ultimately allow us to track the vascular impact of subsequent environmental (i.e. biomechanical and biochemical) stressors, as well as the potential response to therapeutic interventions. "This important study is consistent with a growing literature, indicating that congestion itself may mediate many of the physiological abnormalities in heart failure, such as vascular dysfunction, inflammation, renal dysfunction and hypercoagulability," commented Barry M. Massie, M.D., Editor-in-Chief of the Journal of Cardiac Failure.
