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.
A reproductive medicine specialist at the University at Buffalo has shown that a new compound may improve the fertility of tobacco smokers who have low sperm count and low percentage sperm motility.
According to a University of Pittsburgh-led study published in the December issue of Gastroenterology, medium-sized polyps found in the colon with flexible sigmoidoscopy and subsequently evaluated by full colonoscopy are associated with a significant number of advanced adenomas (high-risk polyps) and cancers.
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.
Clinicians treating patients suffering from tennis elbow often advise them to change the grip size of their racket to alleviate muscle fatigue. A new study of muscle firing patterns in the forearm shows grip size has no relationship to the development of tendonitis.
African-American men with prostate cancer were more likely to report a family history of prostate cancer and breast cancer among siblings than men who did not have prostate cancer, according to researchers at the University of Michigan Comprehensive Cancer Center.
Women who undertake a long-term weight training program produce more biologically active growth hormone, a finding that allows physiologists to understand why weight training improves muscle tone and optimizes metabolic function. The study found that growth hormone was responsive to moderate and heavy exercise regimens having 3-12 repetitions with varying weight loading, suggesting women need to have heavy loading cycle or workout in their resistance training routines, as it helps to build muscle and bone.
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.
Researchers in the OHSU Digestive Health Center are developing a system through which clinicians hope to more easily identify people at increased risk for the disease. Early identification allows physicians to identify malignancies sooner and begin aggressive treatment quicker. Only patients at high risk for pancreatic cancer will be monitored.
