A new ultrasound technique – elastography – would enable doctors identify the harmless breast lumps and cancer instantly, without performing biopsy, developed by researchers from Northeastern Ohio Universities College of Medicine, USA.
The first human trial of gene transfer therapy for erectile dysfunction (ED) indicates that gene therapy that lasts for months and eliminates the patient’s need for on-demand drugs (such as Viagra and Cialis), could become the future treatment of choice for this common problem, according to a paper in the most recent issue of Human Gene Therapy.
Topics include: impact of melting glaciers on near-shore ecosystems; discovery of intact egg clusters from a Middle Cambrian oceanic invertebrate; biotic recovery from the End-Permian mass extinction; fossil evidence of unusual animal foraging behavior; dating the destruction of Herod the Great’s harbor at Caesarea; El Ni?o-related landslides along the Big Sur coastline, and evidence of flowing water at Mars’ Erebus crater. The GSA Today science article describes dynamics of ice sheet recession in East Antarctica.
Brain cells derived from human embryonic stem cells improved the condition of rats with Parkinson’s-like symptoms dramatically, but the treatment caused a significant problem — the appearance of brain tumors — that scientists are now working to solve. The study is featured on the cover of the November issue of Nature Medicine.
Scientists have combined two molecules that occur naturally in blood to engineer a molecular complex that uses solar energy to split water into hydrogen and oxygen, says research published today in the Journal of the American Chemical Society.
The advisory committee of the American College of Obstetricians and Gynecologists confirms that the antidepressant Paxil (paroxetine) may cause fetal cardiac malformations. Obstetricians suggested to shun the antidepressants in pregnancy, if possible.
A new study shows how psychological stress induces abnormalities in skin structure and function that could initiate or worsen skin disorders such as psoriasis and atopic dermatitis. The study provides a link for understanding the roles psychological stress and glucocorticoid, a type of steroid, play in skin disorders and shows that blocking glucocorticoid can prevent skin abnormalities induced by psychological stress.
Two Iowa State University computer scientists are developing image-analysis software and related hardware that will measure the quality of colonoscopy procedures. Their goal is better procedures and better health for patients.
A protein called NMNAT protects against nerve cell degeneration in fruit flies and mice. The finding begs the question if a drug might be developed that could stimulate extra protein production and thus neuronal protection — both in injured cells and in those degenerating because of disease.
The first human study using gene transfer to treat erectile dysfunction (ED) shows promising results and suggests the potential for using the technology to treat overactive bladder, irritable bowel syndrome and asthma, according to the researchers.
