ScienceIndex.com is a Dermatology and Endocrinology Sciences 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 Dermatology and Endocrinology. While the Dermatology section covers the physiology and pathology of the skin, the Endocrinology section covers the glands of internal secretion, the endocrine glands, and the hormones which they synthesize and secrete.
ScienceIndex.com's Health Technologies Category covers prevention, treatment, and management of illness by medical health professions. Its eighteen sections include Audiology, Dentistry, Dermatology, Endocrinology, Gastroenterology, Healthcare, Immunology, Medicine, Neurology, Nutrition, Oncology, Pathology, Pharmacology, Psychiatry, Psychology, Radiology, Rheumatology, and Surgery. Users can receive alerts for newly published content in this category by subscribing to ScienceIndex.com's Health Technologies Category RSS feed.
ScienceIndex.com's new Dermatology section covers the physiology and pathology of the skin. It currently contains 7,000 articles partly derived from almost 50 scientific Dermatology journals. The latest articles in this category are also available through a Dermatology Section RSS feed. One of the latest additions to this section covers the development of a skin aging scale by using dermoscopy. Since skin aging cannot exclusively be detected by the naked eye but can be determined more easily by dermoscopy, the authors examined telangiectasia, vascular changes, pigmentation changes, seborrheic keratosis, actinic keratosis, periorbital comedones and cysts, superficial- deep- criss-cross wrinkles by dermoscopy and scored skin aging with the help of dermoscopic photoaging scale (DPAS). They conclude that DPAS is a reliable and valid diagnostic tool that can evaluate photoaged skin quantitatively by the help of objective criteria so can be used to evaluate the effect of preventive and therapeutic applications for skin aging. Another study examined seasonal and annual variation in the intensity of facial wrinkles. The authors found an apparent annual variation in skin conductance, which is apparently caused by skin dryness, and found annual variation in the level of skin brightness, which is supposed to be caused by sun tan.
ScienceIndex.com's new Endocrinology section covers the glands of internal secretion, the endocrine glands, and the hormones which they synthesize and secrete. It currently contains almost 20,000 articles partly derived from nearly 100 scientific Endocrinology journals. The latest articles in this section are also available through a Endocrinology Section RSS feed. One recently included article in this section covers isolation of pancreatic progenitor cells with the surface marker of hematopoietic stem cells. With a newly invented culture system, pancreatic progenitor cells were induced to differentiate to endocrine and exocrine cells. Cells differentiated from c-Kit-positive cells contained more insulin-producing cells and secreted more insulin in response to glucose stimulation than that from c-Kit-negative cells. The authors' results suggest that c-Kit could be used to isolate pancreatic progenitor cells and the new culture system permitted pancreatic progenitor cells to differentiate to mature endocrine cells. Another study demonstrates that hypoglycaemia is associated with the absence of a decrease in diurnal macular thickness in patients with diabetic macular oedema (DME). In the study population as a whole, the lower the mean diurnal blood glucose, the smaller the decrease in central macular thickness (CMT) during the day.
The Sciences Social Network currently contains over 2.06 million posts distributed among its' 75 categories. 84,000 users monitor over 15,200 journals publishing within the scope of the site. Due to a faster publishing process, the delay between original publication and appearance at ScienceIndex.com is now no more than 16 hours. The site provides an advanced search feature which suggests up to ten closely related articles for a search and every displayed post.
