Ejaculation is the physiological process that describes the expulsion of the semen from the urethra. This physiological response is a remarkably sophisticated phenomenon that requires the participation of several stereotyped motor patterns for its expression and when taking place, it starts a constellation of short- and long-lasting physiological and behavioural processes. Little is known about the neural mechanisms accounting for its activation. It has been recently proposed that a central pattern generator located at the spinal level is involved in the control of ejaculation. The aim of this paper is to review the evidence supporting this notion. Thus, the mechanics of ejaculation, its anatomical substrates and innervation are described. Besides, evidence from behavioural, physiological and pharmacological studies that support the existence of an intraspinal rhythm modulating the ejaculatory response are provided. Data are discussed in the context of the physiology of male sexual function.

Electronic band evolution between Lieb and kagome nanoribbons.

We investigate the electronic properties of nanoribbons made out of monolayer Lieb, transition, and kagome lattices using the tight-binding model with a generic Hamiltonian. It allows us to map the evolutionary stages of the interconvertibility process between Lieb and kagome nanoribbons by means of only one control parameter. Results for the energy spectra, the density of states, and spatial probability density distributions are discussed for nanoribbons with three types of edges: straight, bearded, and asymmetric.

Background: Young gay, bisexual, and other men who have sex with men have been referred to as a "hard-to-reach" or "hidden" community in terms of recruiting for research studies. With widespread internet use among this group and young adults in general, web-based avenues represent an important approach for reaching and recruiting members of this community. However, little is known about how participants recruited from various web-based sources may differ from one another.

Self-organization under out-of-equilibrium conditions is ubiquitous in natural systems for the generation of hierarchical solid-state patterns of complex structures with intricate properties. Efforts in applying this strategy to synthetic materials that mimic biological function have resulted in remarkable demonstrations of programmable self-healing and adaptive materials. However, the extension of these efforts to multifunctional stimuli-responsive solid-state materials across defined spatial distributions remains an unrealized technological opportunity.

Autism spectrum disorder (ASD) is a pervasive neurobehavioral condition characterized by disruption of behavioral and emotional patterns in individuals with this condition. Given that various environmental and genetic factors play a fundamental role in the pathophysiology of ASD, it can be said that ASD is a multifaceted disease. This study used scientific databases including Google Scholar, PubMed, Scopus, and Semantic Scholar.

Purpose: The use of social media is transforming physician-patient communication, mainly in the field of medical oncology. The pattern of social media use by medical oncologists is poorly studied. Therefore, we developed a survey to understand the preferences, experiences, opinions, and expectations of Italian medical oncologists and oncology fellows regarding the use of social media in cancer medicine to identify the different profiles of social media users.
