Fracture of the penis is a well-recognized yet relatively uncommon urologic event. Forceful, blunt trauma with lateral bending of the penis in an erect state typically results in a transverse rupture of the tunica albuginea of the corpus cavernosum. Longitudinal tears of the corpus cavernosum are by themselves considered infrequent. We present a rare case of a patient with longitudinal rupture of the distal corpus cavernosum with concomitant extension to the corpus spongiosum causing partial urethral disruption as a result of trauma during sexual intercourse...

Priapism is characterized by persistent penile erection in the absence of sexual arousal or desire that does not subside with orgasm. Although relatively uncommon, it is a genitourinary emergency that necessities prompt work-up and appropriate management, as there is a time-dependent relationship between total duration of erection and an increasing risk of permanent erectile dysfunction. Confirming the type of priapism is key to proper management, but the majority of cases presenting to the emergency department are ischemic in nature...

Phenotypic characterization of animal genetic resources (AnGR) involves identification of distinct breed populations, describing their external and production characteristics in a given environment and management, and taking into account the social and economic factors that affect them. A survey involving 346 livestock farmers was conducted in the 15 counties of Liberia to collect data on production practices and phenotypic characteristics of beef cattle. A pre-tested structured questionnaire, focus group discussions, and in-depth interviews were utilized in data collection...

Background: Condoms remain the main protection against sexually transmitted infections (STIs) when used correctly and consistently. Yet, there are many reported barriers to their use such as negative attitudes, reduced sexual pleasure, fit-and-feel problems and erection difficulties. The UK home-based intervention strategy (HIS-UK) is a behaviour change condom promotion intervention for use among young men (aged 16-25 years) designed to increase condom use by enhancing enjoyment of condom-protected intercourse...

Plant architecture is a key agronomical factor determining crop yield, which has been a major target of cereal crop domestication. The plant architecture transition from the prostrate tiller of typical African wild rice (O. barthii) to the erect tiller of African cultivated rice (Oryza glaberrima) was a key step during African rice domestication. Here we show that PROG7 (PROSTRATE GROWTH 7), a zinc-finger transcription factor gene on chromosome 7, was required for the prostrate growth of African wild rice. Mutations in the promoter region of prog7 reduced the level of gene expression in the tiller base, leading to erect growth in African cultivated rice...

The Pelagia is a recently delineated group of fishes, comprising fifteen families formerly placed in six perciform suborders. The Pelagia was lately recognized as it encompasses huge morphological diversity and only in the last few years have large-scale molecular phylogenetic studies been undertaken that could unite such morphological disparate lineages. Due to the recent erection of Pelagia, the composition of the taxon is not entirely certain. Five families of the former perciform suborder Stromateoidei have been identified as pelagians...

INTRODUCTION: Prosthesis-assisted penile reconstruction has been performed extensively to restore a cosmetically acceptable phallus. However, a large number of patients will undergo revision surgery for various prosthesis-related complications. AIM: To develop a 1-stage prosthesis-free dynamic cavernosa reconstruction method using bilateral innervated gracilis muscles and to investigate the feasibility and reliability of the surgical design. METHODS: 10 fresh cadavers were dissected to assess the availability of bilateral gracilis muscles for functional cavernosa rebuilding...

500Ma ago the terrestrial habitat was a barren, unwelcoming place for species other than, for example, bacteria or fungi. Most probably, filamentous freshwater algae adapted to aerial conditions and eventually conquered land. Adaptation to a severely different habitat apparently included sturdy cell walls enabling an erect body plan as well as protection against abiotic stresses such as ultraviolet radiation, drought and varying temperature. To thrive on land, plants probably required more elaborate signaling pathways to react to diverse environmental conditions, and phytohormones to control developmental programs...

Histamine (HA) is a pleiotropic biogenic amine synthesized exclusively by histidine decarboxylase (HDC) in most mammalian tissues. The literature on the role of HA within the male gonad has expanded over the last years, attracting attention to potential unexpected side-effects of anti-histamines on testicular function. In this regard, HA receptors (HRH1, HRH2 and HRH4) have been described in Leydig cells of different species, including human. Via these receptors, HA has been reported to trigger positive or negative interactions with the LH/hCG signaling pathway depending upon its concentration, thereby contributing to the local control of testicular androgen levels...

OBJECTIVE: To introduce a patient-reported erection fullness scale (% fullness) following robot-assisted radical prostatectomy as a qualitative adjunct to the IIEF-5 and as a 90-day predictor of two-year potency outcomes. PATIENTS AND METHODS: Prospective data was collected from 540 men with preoperative IIEF-5 22-25 who underwent RARP by a single surgeon, of which 299 had complete data at all time points up to 2 years. In addition to standard assessment tools (IIEF-5 and erections sufficient for intercourse), patients were asked to "indicate the fullness you are able to achieve in erections compared to before surgery?" (0-10…100%)...

Policy Points: Historically, in addition to economic and technical hurdles, state and federal health information privacy laws have been cited as a significant obstacle to expanding electronic health information exchange (HIE) in the United States. Our review finds that over the past decade, several helpful developments have ameliorated the legal barriers to HIE, although variation in states' patient consent requirements remains a challenge. Today, health care providers' complaints about legal obstacles to HIE may be better understood as reflecting concerns about the economic and competitive risks of information sharing...

A 41-year-old woman presented with a large painful and tender mass of the left side of her neck located just below the angle of the mandible. She was also complaining of frequent attacks of symptoms ranging from dizziness upon resuming the erect position to frank syncope. Color-coded duplex showed a large well-vascularized vascular mass at the level of the carotid bifurcation, suggesting the diagnosis of a carotid body tumor (CBT). A computerized tomographic angiography confirmed the diagnosis of a CBT, which measured 5...

Coal fly ash (CFA) is an industrial waste generated in huge amounts worldwide, and the management of CFA has become an environmental concern. Recovery of valuable metals from CFA is one of the beneficial reuse options of CFA. Rhenium (Re) is one of the rarest metals in the Earth's crust and one of the most expensive metals of strategic significance in the world market. A CFA at the Jungar Thermal Power Plant, Inner Mongolia, China, contains more Re than two alkaline soils in the surrounding region. Pot experiments were undertaken to grow lucerne (Medicago sativa) and erect milkvetch (Astragalus adsurgens) in a loessial soil and an aeolian sandy soil amended with different rates (5%, 10%, 20%, and 40%) of CFA...
