This paper concerns the changes occurred over both decennial and millennial spans of time in a sponge assemblage present in coralligenous biogenic build-ups growing at 15 m depth in the Ligurian Sea (Western Mediterranean). The comparison of the sponge diversity after a time interval of about 40 years (1973-2014) showed a significant reduction in species richness (about 45%). This decrease affected mainly the massive/erect sponges, and in particular the subclass Keratosa, with a species loss of 67%, while the encrusting and cavity dwelling sponges lost the 36% and 50%, respectively...

The functional three dimensional micro-nanostructures (3D-MNS) play crucial roles in integrated and miniaturized systems because of the excellent physical, mechanical, electric and optical properties. Nanoimprint lithography (NIL) has been versatile in the fabrication of 3D-MNS by pressing thermoplastic and photocuring resists into the imprint mold. However, direct nanoimprint on the semiconductor wafer still remains a great challenge. On the other hand, considered as a competitive fabrication method for erect high-aspect 3D-MNS, metal assisted chemical etching (MacEtch) can remove the semiconductor by spontaneous corrosion reaction at the metal/semiconductor/electrolyte 3-phase interface...

BACKGROUND: Sexuality is an essential part of life; however, erectile dysfunction (ED) has been one of the most common complaints among men with sexual health issues all over the world. ED includes dysfunction in erection and penile erectile pain. In Vietnam, ED is a subject a not readily discussed. Thus, relatively little is known about ED among Vietnamese men. AIMS: To identify the prevalence of ED and its associated variables and the need for treatment of ED among married men in Vietnam...

Androgen signaling, via receptor binding, is critical for regulating the physiological and morphological foundations of male-typical reproductive behavior in vertebrates. Muscles essential for male courtship behavior and copulation are highly sensitive to androgens. Differences in the distribution and density of the androgen receptor (AR) are important for maintaining dimorphic musculature and thus may provide for anatomical identification of sexually selected traits. In Lythrypnus dalli, a bi-directional hermaphroditic teleost fish, both sexes produce agonistic approach displays, but reproductive behavior is sexually dimorphic...

Background: Few studies have examined smoking and female sexual difficulties. The aim of this study was to investigate the association between current tobacco smoking and sexual difficulties in Australian men and women. Methods: Data for this study came from the Second Australian Study of Health and Relationships (2012-13), which includes a representative sample of 18427 sexually active Australian adults (aged 16-69 years). The main study and outcome measures were tobacco smoking and sexual difficulties. A multiple logistic regression analysis was conducted to adjust for potential confounders...

Priapism is a prolonged erection without sexual stimulation. In most cases it requires prompt management in order to avoid long-term consequences such as erectile dysfunction or penile deformity. Priapism is rare in children, but haematological diseases play an important role. The diagnosis is generally not difficult. Blood gas analysis and Doppler sonography are used to establish the form of priapism and determine its further management. The management of low-flow priapism consists of immediate blood aspiration and intracavernosal injection of sympathomimetic drugs as needed...

Rice leaf angle is determined by lamina joint and an important agricultural trait determining leaf erectness and hence the photosynthesis efficiency and grain yield. Genetic studies reveal a complex regulatory network of lamina joint development; however, the morphological changes, cytological transitions, and underlying transcriptional programming remain to be elucidated. A systemic morphological and cytological study reveals a dynamic developmental process and suggests a common but distinct regulation of lamina joint...

A male aged 44 years presented to the emergency department with a 1-week history of intermittent right-sided abdominal pain radiating to the midline. Examination demonstrated a tender right upper quadrant with voluntary guarding and a low grade fever. One week previously, he had been admitted to hospital after an isolated, self-terminating seizure secondary to an deliberate venlafaxine overdose. His upper abdominal symptoms started immediately postseizure but at the time were attributed to musculoskeletal chest pain by the discharging team...

REVIEW
James Frame
The 'waterfall effect' is a descriptive term to indicate a sliding ptosis of parenchymal breast tissue over a fixed or encapsulated implant. It occurs more frequently than surgeons anticipate and especially over the longer term after augmentation. Certain breast implants are more prone to contribute to this problem as are implants placed in submuscular pockets that ride high, especially in women with anatomical musculoskeletal variance or asymmetry. This article describes the aetiology of sliding ptosis in more detail, the relevant anatomy and the surgical correction...

Inferring the origins of hybrid taxa based on morphology alone is difficult because morphologically similar hybrids can arise from hybridization between different populations of the same parental species or be produced by hybridization of different parental species. In this study, we investigated the origins of two semi-creeping taxa in Melastoma, which are morphologically similar to a natural hybrid, M. intermedium, by sequencing a chloroplast intergenic spacer, nuclear ribosomal internal transcribed spacer and two low-copy nuclear genes (tpi and cam) in these taxa and their putative parental species...

Erectile dysfunction (ED) is an evolving health problem with growing incidence in the ageing male population with potentially predictive value for cardiovascular and other chronic diseases. ED shares the common cardiovascular risk factors. The aetiology of ED is numerous including neurogenic, psychogenic, arteriogenic, and venogenic reasons. The origin of arteriogenic ED is frequently atherosclerosis. Patients not adequately responding to conservative measures including oral medication are often referred to further vascular diagnostics and therapy...

OBJECTIVES: Snakebite severity corresponds to size of snake because the amount of venom a snake injects is positively associated with snake size. Because fang marks are often present on snakebite patients, we tested whether the relationship between snake length and distance between fang puncture wounds can be generalized for rattlesnakes of genus Crotalus. METHODS: We measured 2 interfang distances from 79 rattlesnakes of both sexes, 5 species, and varying body length: 1) distance between fang bases in anesthetized snakes, and 2) distance between fang punctures in a membrane-covered beaker bitten defensively...

Arctic and alpine treelines worldwide differ in their reactions to climate change. A northward advance of or densification within the treeline ecotone will likely influence climate-vegetation feedback mechanisms. In our study, which was conducted in the Taimyr Depression in the North Siberian Lowlands, w present a combined field- and model-based approach helping us to better understand the population processes involved in the responses of the whole treeline ecotone, spanning from closed forest to single-tree tundra, to climate warming...

Rapid climate warming has resulted in shrub expansion, mainly of erect deciduous shrubs in the Low Arctic, but the more extreme, sparsely vegetated, cold and dry High Arctic, is generally considered to remain resistant to such shrub expansion in the next decades. Dwarf shrub dendrochronology may reveal climatological causes of past changes in growth, but is hindered at many High Arctic sites by short and fragmented instrumental climate records. Moreover, only few High Arctic shrub chronologies cover the recent decade of substantial warming...

BACKGROUND: To ascertain 3-year urinary continence (UC) and sexual function (SF) recovery following robot-assisted radical prostatectomy (RARP) for clinically high-risk prostate cancer (PCa). METHODS: Retrospective analyses of a prospectively maintained database for 769 patients with D'Amico high-risk PCa undergoing RARP at two tertiary care centers in the United States and Europe between 2001 and 2014. The association between time since RARP and recovery of UC (defined as 0 pad/one safety liner per day) and SF (defined as sexual health inventory for men (SHIM) score ⩾17) was tested in separate preoperative and post-operative Cox-proportional hazards regression models...
