Needle Guide Type Affects Prostate Biopsy Complications
MONDAY, June 9 (HealthDay News) -- In men undergoing transrectal prostate biopsy, the use of a disposable ultrasound needle guide may significantly reduce the rate of infectious complications, according to research published in the June issue of Urology.
Castration-Resistant Prostate Cancer Mechanism Proposed
TUESDAY, June 3 (HealthDay News) -- Metastatic prostate cancers may adapt to low systemic testosterone levels and maintain intratumoral androgens by modulating enzymes involved in intracrine steroidogenesis and androgen catabolism. This mechanism may explain why nearly all patients eventually develop castration-resistant disease despite anorchid serum androgen levels, researchers report in the June 1 issue of Cancer Research.
Study Sheds Light on Role of T3 in Male Rat Reproduction
MONDAY, June 2 (HealthDay News) -- Researchers have found expression of iodothyronine 5'-deiodinase (5'-D), an enzyme that creates the active form of triiodothyronine (T3) from thyroxine (T4), in several tissues in the male reproductive tract, according to study findings released online May 8 in advance of publication in Endocrinology. These findings may help shed light on the poorly understood role of thyroid hormones in regulating reproductive function in reproduction organs other than gonads.
Tomato Ingredient May Offer Prostate Protection
MONDAY, June 2 (HealthDay News) -- The ketosamine FruHis, found in tomato powder, may interact with lycopene to offer protection against prostate cancer, according to research from rat studies published in the June 1 issue of Cancer Research.
