Epidemiologic studies have failed to support the hypothesis that circulating androgens are positively associated with prostate cancer risk and some recent studies have even suggested that high testosterone levels might be protective particularly against aggressive cancer. We tested this hypothesis by measuring total testosterone, androstanediol glucuronide, androstenedione, DHEA sulfate, estrad...

BACKGROUND Prostate cancer mortality is higher among black American men than among white American men. We investigated whether racial disparities in outcomes of clinically localized prostate cancer vary by treatment (surgery, radiation therapy, or nonaggressive treatment). METHODS Merged Surveillance, Epidemiology, and End Results Program (SEER) and Medicare files provided data (on treatment ...

Central giant cell granuloma (CGCG) is described by the World Health Organization (WHO) as a localized and benign but sometimes aggressive lesion characterized by an osteolytic proliferation consisting of fibrous tissue with hemorrhage and hemosiderin deposits, the presence of osteoclastlike giant cells and reactive bone formation.1 Its etiology is unknown. Clinically, CGCG patients may present...

http://dx.doi.org/10.1016/j.anbehav.2014.07.018 0003-3472/© 2014 The Association for the Study of A Male courtship signals often stimulate the production of sex steroids in both female and male receivers. Such effects benefit signallers by increasing receptivity in females, but impose costs on signallers by promoting sexual behaviour and aggression in male competitors. To resolve this androgen-...

Abstract There is a growing evidence that consistent interindividual differences in behavior, is, behavioral types, can play an important role key ecological processes such as predator–prey interactions, which turn have direct implications on biological control. Behavioral types of generalist predators may affect these interactions through individual predators’ prey preferences and the breadth ...

STUDY DESIGN Prospective randomized clinical trial. METHODS AND MEASURES Thirty-six patients who had a primary anterior cruciate ligament reconstruction (ACL-R) with a semitendinosus-gracilis (STG) autograft from a single orthopedic surgeon were prospectively randomized into 2 groups. Nineteen patients were randomized to the aggressive group (53% male, mean age 30.1 + 10.5 y) and 17 to the no...

Background—A high restenosis rate has been reported at the edges (“edge restenosis”) of P radioactive stents with an initial activity level of 3 to 12 mCi. This edge effect might be due to balloon injury and to a low dose of radiation at the stent margins. The aim of this study was to evaluate whether the implantation of P radioactive stents with a higher activity level (12 to 21 mCi) combined ...

OBJECTIVE The aim of this study was to systematically review and evaluate the quality of current evidence about fluid therapy (FT) in acute pancreatitis (AP). BACKGROUND Intravenous FT is thought to be important in the early management of patients with AP. Clinically relevant questions remain regarding the type of fluid, the rate of administration, and the goal of FT. METHODS A comprehensiv...

Background: Non-melanoma skin cancer is the most common malignant tumor in humans. The role of ultraviolet radiation is well-known in the pathogenesis of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). CD10 is a zinc-dependent metallopeptidase known as common acute lymphoblastic leukemia antigen (CALLA). Although CD10 expression has been investigated in some cutaneous tumors, to o...
