Pharmacology & Psychiatry @ ScienceIndex.com
Mannheim, Germany (PRWEB) May 10, 2012
ScienceIndex.com is a health social network established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society. In the field of Health Sciences, the site has now included the two new categories Pharmacology and Psychiatry. While the Pharmacology category covers composition, uses, and effects of drugs, the Psychiatry category covers the diagnosis, treatment, and prevention of mental and emotional disorders.
ScienceIndex.com's Health Category covers the effects of disease and medical treatment on the overall condition of organisms. Its eighteen subsections include Audiology, Dentistry, Dermatology, Endocrinology, Gastroenterology, Healthcare, Immunology, Medicine, Neurology, Nutrition, Oncology, Pathology, Pharmacology, Psychiatry, Psychology, Radiology, Rheumatology, and Surgery. Users can receive alerts if new content has been posted in this category by subscribing to ScienceIndex.com's Health RSS feed.
ScienceIndex.com's Pharmacology category covers composition, uses, and effects of drugs. It currently contains 29,615 articles partly derived from 154 scientific journals. The latest articles in this category are also available through an Pharmacology Sciences RSS feed. One of the latest additions assessed the in vivo antitumor efficacy of a polypeptide-based poly-L-glutamic acid-gemcitabine conjugate (PG-G) in tumor-bearing mice. The antitumor effects of PG-G were superior to those of unconjugated gemcitabine in both single and four-consecutive dosing studies. The authors' study demonstrates that the PG-G formulation shows a significant antitumor activity in terms of tumor growth inhibition and shrinkage and that the PG-G dose regimen need to be optimized to minimize side effects and render it a potential anticancer therapeutic. Another recently published article in this category reviews prescribing errors in hospital practice. Errors have been reported in handwritten descriptions of almost 15 percent and with electronic prescribing of up to 8 percent of orders.
ScienceIndex.com's Psychiatry category covers the diagnosis, treatment, and prevention of mental and emotional disorders. It currently contains 7,772 articles partly derived from 63 scientific journals. The latest articles in this category are also available through a Psychiatry Sciences RSS feed. One recently included article in this category studies the effect of purpose in life on the relation between Alzheimer disease (AD). The authors tested the hypothesis that purpose in life reduces the deleterious effects of AD pathologic changes on cognition in advanced age. Their results indicate that higher levels of purpose in life reduce the deleterious effects of AD pathologic changes on cognition in advanced age. Another recently published article covers polypharmacy with antipsychotics, antidepressants, or benzodiazepines and mortality in schizophrenia. While polypharmacy is widely used in the treatment of schizophrenia, it is believed to have major adverse effects on the well-being of patients. The authors of this study linked national databases of mortality and medication prescriptions among a complete nationwide cohort of 2,588 patients hospitalized in Finland with a diagnosis of schizophrenia between 2000 and 2007. Benzodiazepine use was associated with a substantial increase in mortality, and this was attributable to suicidal deaths and to nonsuicidal deaths. In contrast, the use of an antidepressant or several concomitant antipsychotics was not associated with an increase in mortality.
