In this paper, we introduce our novel renal subcapsular xenograft model for the study of human penile urethral and clitoral development. We grafted fifteen intact fetal penes and clitorides 8-11 weeks fetal age under the renal capsules of gonadectomized athymic mice. The mice were treated with a subcutaneous pellet of dihydrotestosterone (DHT), diethylstilbestrol (DES) or untreated with hormones. Xenografts were harvested after fourteen days of growth and analyzed via serial histologic sectioning and immunostaining for Ki-67, cytokeratins 6, 7 and 10, uroplakin and the androgen receptor...

Human height has attracted empirical interest from a variety of psychological perspectives. However, little research has explored height from the perspective of sexual minority men, inclusive of their height beliefs, height preferences, height dissatisfaction, experiences of heightism, and height-related quality of life impairment. We explored these height variables in 2733 sexual minority men who completed a survey distributed nationwide to Australian and New Zealander users of geosocial-networking smartphone applications...

BACKGROUND: The costs of oncology treatments are increasing, due to the rising prevalence of malignant diseases and the introduction of expensive novel anti-cancer agents. The new European Society for Clinical Oncology (ESMO) has recently developed a new parametric system to evaluate the clinical benefit of drugs. The Magnitude of Clinical Benefit Scale (ESMO-MCBS) compares the contribution of a novel drug based on overall and progression-free survival and quality of life with those of current treatment options...

BACKGROUND: The standard postsurgical options for low-grade gliomas include watchful waiting or radiotherapy depending on the risk factors for recurrence. The use of chemotherapy for the treatment of this disease is generally controversial, although the recently published results of the first of two large randomized phase III clinical trials (RTOG 9802 a EORTC 22033-26033), focusing on the evaluation of chemotherapy for the upfront treatment of newly diagnosed low-grade gliomas, are reassuring in this respect...

BACKGROUND: The optimal treatment for low-grade gliomas remains controversial. Neurosurgery, radiotherapy, and chemotherapy are the main treatment options. Despite advances in oncology, there are still a lot of uncertainties, and the optimal sequences, combinations, and timings of these procedures have not yet been optimized. It is still unclear whether temozolomide can replace effective, but toxic PCV chemotherapy (procarbazine, lomustine, vincristine) and whether temozolomide can be used upfront alone instead of radiotherapy alone...

Dulama Richani, Robert B Gilchrist
BACKGROUND: The LH surge induces great physiological changes within the preovulatory follicle, which culminate in the ovulation of a mature oocyte that is capable of supporting embryo and foetal development. However, unlike mural granulosa cells, the oocyte and its surrounding cumulus cells are not directly responsive to LH, indicating that the LH signal is mediated by secondary factors produced by the granulosa cells. The mechanisms by which the oocyte senses the ovulatory LH signal and hence prepares for ovulation has been a subject of considerable controversy for the past four decades...

Background: The scale-up of effective malaria control in the last decade has resulted in a substantial decline in the incidence of clinical malaria in many countries. The effects on the proportions of asymptomatic and submicroscopic infections, and on transmission potential are yet poorly understood. Methods: In Papua New Guinea, vector control has been intensified since 2008, and improved diagnosis and treatment introduced in 2012. Cross-sectional surveys were conducted in Madang Province in 2006 (n=1280), 2010 (n=2117) and 2014 (n=2516)...

Pest-induced changes in plant reflectance are crucial for the development of pest management programs using remote sensing. However, it is unknown if plant reflectance data is also affected by foliar insecticides applied for pest management. Our study assessed the effects of foliar insecticides on leaf reflectance of soybean. A 2-yr field trial and a greenhouse trial were conducted using randomized complete block and completely randomized designs, respectively. Treatments consisted of an untreated check, a new systemic insecticide (sulfoxaflor), and two representatives of the most common insecticide classes used for soybean pest management in the north-central United States (i...

The diagnostic evaluation of acute chest pain has been augmented in recent years by advances in the sensitivity and precision of cardiac troponin assays, new biomarkers, improvements in imaging modalities, and release of new clinical decision algorithms. This progress has enabled physicians to diagnose or rule-out acute myocardial infarction earlier after the initial patient presentation, usually in emergency department settings, which may facilitate prompt initiation of evidence-based treatments, investigation of alternative diagnoses for chest pain, or discharge, and permit better utilization of healthcare resources...

Background: The increase in antibiotic resistance in Gram-negative bacteria and the limited therapeutic options due to the shortage of new antibiotics have increased the interest of the 'old' antibiotic fosfomycin in the treatment of infections. However, there are contradictory reports on the pharmacodynamics of and emergence of resistance to fosfomycin. Methods: Time-kill assays were performed with 11 ESBL-positive and 3 ESBL-negative strains, exposing the bacteria to 2-fold static concentrations from 0...

Chinese tallowtree, Triadica sebifera (L.) Small (Euphoriaceae), is one of the most aggressive weeds of coastal wetlands and forests of the southeastern United States. The lack of specialist herbivores in the invaded range may be one of the factors that contribute to the invasive nature of this weed. Chinese tallowtree has been the target of a classical biological control project since 2006. Several herbivore species are being tested for biological control of Chinese tallowtree. Concurrently, an adventive herbivore, Caloptilia triadicae Davis (Lepidoptera: Gracillariidae), was found feeding on Chinese tallowtree in the southeastern United States in 2004 and now occurs throughout the invaded range...

Our use of modern cardiovascular imaging tools has not kept pace with their technological development. Diagnostic errors are common but seldom investigated systematically. Rather than more impressive pictures, our main goal should be more precise tests of function which we select because their appropriate use has therapeutic implications which in turn have a beneficial impact on morbidity or mortality. We should practise analytical thinking, use checklists to avoid diagnostic pitfalls, and apply strategies that will reduce biases and avoid overdiagnosis...

<p>Aging gracefully has taken on a whole new meaning over the past few decades as new aesthetic treatments have been developed and are becoming more sophisticated by the day. The aging process, which is exacerbated by chronic UV exposure, results in dyspigmentation, loss of skin laxity, precancerous and cancerous skin lesions, fat loss and redistribution, and bone resorption. Laser and light devices can be used to treat dyspigmentation, while neuromodulators and soft tissue fillers can be used for rhytides and revolumization...
