There ’s No Such Thing as a ‘Gay Gene,’ a New Study Argues
In 1993, researchers discovered a stretch of DNA on the X chromosome they believed to be linked to male homosexuality. In the years since, the concept of a “gay gene” has been a source of debate within both the scientific community and the general public, inspiring ever-larger follow-up studies over the years. A new study published in Science, thought to be the most comprehensive on the topic, adds important information to that back-and-forth. After studying the DNA of nearly half a million people with varying sexual experiences, the researchers found no evidence of a single “gay gene.” There was some genetic association with self-reported same-sex sexual activity, but environmental factors likely play an even larger role, according to the study. The researchers examined genotyping data and self-reported sexual histories from almost 500,000 (mostly white) people of both sexes who were either participating in genetic research projects, like the U.K. Biobank study, or had purchased genetic testing products from 23andMe and consented to inclusion in the study. Most participants came from the U.K. Biobank study, which involves adults ages 40 to 70, though the paper also included some young adults and adolescents participating in other studies. Among the human genome’s approximately 30,000 genes, the researchers—who have previously presented research on this topic—found five variants related to same-sex sexual activity, though each one on...

HAIR loss treatment: For both men and woman who have noticed far more hair left in bath sinks and hairbrushes turning to pricey and sometimes painful procedures to remedy it might not be needed. Turning to nature might work just as well and there is a vitamin which aids in collagen production and promotes hair growth.

A 74year old woman with alopecia, CAD on Plavix and Non-Hodgkin ’s lymphoma s/p chemotherapy and radiation of the upper abdomen underwent endoscopy to evaluate dysphagia. It revealed a stenotic esophagus with diameter of 12-15 mm. Bougie dilation was performed. Three gastric lesions were seen: A large Paris IIa circumferential lesion extending from 1 cm proxim al to the Z line to 4-5 cm distal to the Z line, a 4cm Paris IIb lesion at the proximal greater curvature lesion and a 2 cm cardia Paris Is lesion.

Abstract Cerebral venous thrombosis (CVT) is an uncommon cause of stroke that mainly affects young adults with known risk factors of prothrombotic conditions, pregnancy, infection, malignancy, and drugs. Dutasteride is a 5α-reductase inhibitor that is used for benign prostate hypertrophy and androgenetic alopecia. To date, CVT caused by dutasteride use has not been reported. A 25-year-old male presented with headache and diplopia. He had taken 0.5 mg of dutasteride every other day for 9 months to treat alopecia. A headache developed 7 months after he started taking medication, and horizontal diplopia occurre...
