Timing of seasonal reproduction is driven by environmental cues acting on the hypothalamic-pituitary-gonadal (HPG) axis. Groups of individuals, or populations, of the same species can exhibit different phenology despite facing similar environmental cues or living in the same habitat (i.e., seasonal sympatry). The mechanisms giving rise to population-level differences in reproductive timing are not fully understood, particularly for females. We studied the dark-eyed junco, a songbird with migratory and sedentary (i.e., resident) populations that live in overlapping distributions during winter. In early spring, residents initiate breeding and associated behaviors, including territory establishment and formation of pair bonds, while migrants prepare to depart for their breeding grounds. We tested whether migrant and resident hormonal response to upstream hormonal stimulation differed during this time period. We collected blood from free-living females in early spring, and challenged them with repeated gonadotropow the ovarian response to upstream stimulation changes during the transition to reproduction. INTRODUCTION Our objective was to provide guidelines covering all aspects of intermittent catheterisation (intermittent self-catheterisation and third-party intermittent catheterisation). MATERIALS AND METHODS A systematic review of the literature based on Pubmed, Embase, Google scholar was initiated in December 2014 and updated in April 2019.  https://www.selleckchem.com/products/Decitabine.html  Given the lack of robust data and the numerous unresolved controversial issues, guidelines were established based on the formal consensus of experts from steering, scoring and review panels. RESULTS This allowed the formulation of 78 guidelines, extending from guidelines on indications for intermittent catheterisation, modalities for training and implementation, choice of equipment, management of bacteriuria and urinary tract infections, to the implementation of intermittent catheterisation in paediatric, geriatric populations, benign prostatic hyperplasia patients and continent urinary diversion patients with a cutaneous reservoir as well as other complications. These guidelines are pertinent to both intermittent self-catheterisation and third-party intermittent catheterisation. CONCLUSION These are the first comprehensive guidelines specifically aimed at intermittent catheterisation and extend to all aspects of intermittent catheterisation. They assist in the clinical decision-making process, specifically in relation to indications and modalities of intermittent catheterisation options. These guidelines are intended for urologists, gynaecologists, geriatricians, paediatricians, neurologists, physical and rehabilitation physicians, general practitioners and other health professionals including nurses, carers…. There are several animal models of glucocorticoid-induced osteoporosis (GIOP), but each requires a long time to evaluate drug effects. Zebrafish scales are classified as dermal bone and potentially represent a convenient animal model of GIOP because they rapidly regenerate following their removal. We clarified that dexamethasone-treated regenerating scales showed malformations, decreased size and circularity. Anti-osteoporosis drugs rescued the scale malformation phenotype eight-days following the removal of scales. Hence, the dexamethasone-induced regenerating scale malformation model may be a useful animal model for discovering drugs to treat GIOP. High uric acid (UA) is associated with hypertension and cardiovascular disease (CVD), both of which occur disproportionately among African Americans. High UA also predicts greater blood pressure reactivity responses to acute social stress. However, whether UA itself shows reactivity in response to stress is unknown. We evaluated salivary uric acid (sUA) and blood pressure reactivity in response to acute social stress. Healthy African Americans (N = 103; 32 % male; M age = 31.36 years), completed the Trier Social Stress Test. sUA and blood pressure measurements were taken before, during and after the stressor task. sUA showed significant reactivity and recovery, especially among older African Americans. Total sUA activation was also associated with systolic and diastolic blood pressure total activation. Findings illuminate that acute stress may be a way in which UA is implicated in hypertension and CVD, suggesting a critical need to explore UA reactivity as a novel parameter of the acute stress response. This study evaluated polyunsaturated fatty acids (PUFAs) in human kidney epithelial cells exposed to diclofenac (DCL) toxicity. Kidney cells were treated with DCL to induce cytotoxicity and thymoquinone (TQ) was administered to decrease cytotoxic effects. Levels of arachidonic acid (AA, C204n-6), dihomo-gamma-linolenic acid (DGLA, C203n-6), eicosapentaenoic acid (EPA, C205n-3) and docosahexaenoic acid (DHA, C226n-3) were determined by liquid chromatography coupled with tandem mass spectrometry. Cytosolic phospholipase A2 (cPLA2), cyclooxygenase 1 (COX-1) and prostaglandin E2 (PGE2) were measured to evaluate changes in enzyme activity. Immunofluorescence staining and western blot analysis was performed to determine protein levels of COX- 1. Renal cell toxicity was accomplished by DCL and was alleviated by TQ treatment. Diclofenac significantly increased all measured PUFAs while pretreatment with TQ decreased PUFA levels in DCL treated cells. Cytosolic PLA2 and total COX activity was significantly decreased in DCL treated cells. Immunofluorescence staining and western blot analysis confirmed significantly decreased COX-1 levels in DCL and DCL + TQ treated groups. The results of this study reveal that DCL treatment is associated with accumulation of PUFAs in kidney cells. We suggest that PUFA accumulation in DCL toxicity might be a consequence of both cPLA2 and COX-1 inhibition. Thymoquinone administration, along with DCL treatment alleviated the buildup of PUFAs and DCL-induced cell death in kidney cells. BACKGROUND Primary management of localized, intermediate-risk prostate cancer consists of radical prostatectomy (RP), radiotherapy (RT) with short-course androgen deprivation therapy (ADT), or RT alone. The purpose of this study was to determine if these treatment strategies have equivalent overall survival (OS) in patients  less then 55 years old with intermediate-risk prostate cancer. PATIENTS AND METHODS We identified 35,134 patients in the National Cancer Data Base with localized intermediate-risk prostate cancer treated with RP, RT + ADT, or RT from 2004 to 2013. Ten-year OS rates were estimated by the Kaplan-Meier method. Adjusted hazard ratios (HR) with 95% confidence intervals (CI) were computed by multivariate Cox regression. RESULTS A total of 29,920 patients (85.2%) underwent RP, 1393 (4.0%) RT + ADT, and 3821 (10.9%) RT. Median patient age was 51 years old, and median follow-up was 59.9 months. Ten-year OS was estimated to be 94.2% for RP, 80.7% for RT + ADT, and 85.2% for RT (P  less then .0001).
