Close relationships research has examined committed couples (e.g., dating relationships, marriages) using intensive methods that plot relationship development over time. But a substantial proportion of people's real-life sexual experiences take place (a) before committed relationships become "official" and (b) in short-term relationships; methods that document the time course of relationships have rarely been applied to these contexts. We adapted a classic relationship trajectory-plotting technique to generate the first empirical comparisons between the features of people's real-life short-term and long-term relationships across their entire timespan...

Previous studies have revealed that many individuals in settled relationships engage in online sexual activities (OSAs). Considering this, this study examined the influence the perceived infidelity of OSA has on the OSA experiences of individuals in such committed relationships. OSAs involve viewing sexually explicit material, seeking sexual partners, cybersex, and flirting. Taking these specific activities, we measured perceived infidelity concerning OSAs by asking our participants (N = 301) to select either "yes" or "no" in regard to whether they believed each constituted an infidelity...

The objective of this study was to investigate specific interpersonal communication motives that college students use to flirt through texting versus face to face (FtF). Four hundred college students (101 men, 299 women) were surveyed and reported using various communication motives to flirt using texting with a potential romantic partner. College students reported specific motives for flirting. Women reported flirting through text and FtF for pleasure motives significantly more than men, whereas men reported flirting for control and relaxation...

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) has changed the management of aortic dissection by induced remodelling. Beyond reconstructing the true lumen, we describe the concept of False Lumen Intervention to promote Remodelling and Thrombosis (FLIRT) in both type A and B aortic dissection. METHODS: Between 2011 and 2017, 10 patients with aortic dissection (5 type A; 5 type B) underwent FLIRT using a combination of patent foramen ovale (PFO) or atrial septal defect (ASD) occluders, coils and glue...

INTRODUCTION: Linear registration to a standard space is one of the major steps in processing and analyzing magnetic resonance images (MRIs) of the brain. Here we present an overview of linear stereotaxic MRI registration and compare the performance of 5 publicly available and extensively used linear registration techniques in medical image analysis. METHODS: A set of 9693 T1-weighted MR images were obtained for testing from 4 datasets: ADNI, PREVENT-AD, PPMI, and HCP, two of which have multi-center and multi-scanner data and three of which have longitudinal data...

OBJECTIVE: The negative impact of malignant disease on sexual and relational functioning is well documented among adults but scarcely investigated among adolescents and young adults. This study explored the body image, self-perceived attractiveness, and sexual/romantic experiences of Danes diagnosed with cancer at the age of 15 to 29 years. It also aimed to clarify whether self-perceived needs for counseling were in fact met by health care providers. METHODS: All Danes who had been diagnosed with cancer at the age of 15 to 29 years during the period 2009 to 2013 were included in a cross-sectional nationwide questionnaire study...

Extreme sports, defined as sporting or adventure activities involving a high degree of risk, have boomed since the 1990s. These types of sports attract men and women who can experience a life-affirming transcendence or "flow" as they participate in dangerous activities. Extreme sports also may attract people with a genetic predisposition for risk, risk-seeking personality traits, or underlying psychiatric disorders in which impulsivity and risk taking are integral to the underlying problem. In this report, we attempt to illustrate through case histories the motivations that lead people to repeatedly risk their lives and explore psychiatry's role in extreme sports...

Sexual selection for honest behavioral displays of quality has driven the development of remarkably complex courtship behavior in many animal species. Olfactory displays are often overlooked as an area of inquiry compared to auditory and visual displays. Ring-tailed lemur (Lemur catta) scent marking of substrates has been studied extensively, although the male olfactory displays of anointing and wafting tails to females has received relatively little attention. We studied the role of male olfactory displays to females, evaluating whether such signals function as honest, costly signals of male dominance status in two groups of wild L...

Sexual scripts, that is, the mental representations of sexual behavior, are highly influenced by mating strategies and sexual experience. The relationship between these factors and sexual scripts is, however, poorly understood. Therefore, we assessed how long-term (e.g., "sex in a relationship") and short-term (e.g., "one-night stand") strategies, as well as experience with highly scripted sexual practices (BDSM: bondage-discipline, dominance-submission, sadism-masochism), influence verbalized sexual script composition and detailedness...

During adolescence, one's status among peers is a major concern. Such status is often largely a function of popularity and establishing oneself as "cool." While there are conventional avenues to achieving status among adolescents, engaging in adult-like, or pseudomature, behaviors such as substance use or sexual activity is a frequent occurrence. Although past research has examined the consequences of adolescent delinquency, what remains unclear is the long-term fate of adolescents who are both popular and antisocial...

BACKGROUND: In this study, we use assemblage theory to investigate the link between alcohol use and one-night stands. METHODS: The data come from qualitative interviews conducted with 104 young participants in the night-time economy. RESULTS: We show that: (i) alcohol-fuelled sexual explorations (e.g. erotic fantasizing, flirting and sex) are of paramount importance for young partygoers; (ii) sexualized territories (e.g. private parties, rural feasts and the backseat of cars) significantly shape the experience and performance of one-night stands; and (iii) contrary to previous research, one-night stands are to a large degree associated with pleasure-the immediate pleasure of having sex and the long-term pleasure of telling about it to others...

Social environments can have an impact on the interactions between the sexes, specifically pre-courtship behaviors. Sexual selection theory may explain social interactions of the sexes, where males display and attract mates more than females. These behaviors may intensify in a sexual environment. It was hypothesized that individuals would display more in a sexualized environment compared to a non-sexualized location. This research sampled N = 880 participants at a university in a southern state in North America and asked which unisex sunglasses they preferred...

BACKGROUND: Flies have some of the most elaborate visual systems in the Insecta, often featuring large, sexually dimorphic eyes with specialized "bright zones" that may have a functional role during mate-seeking behavior. The fast visual system of flies is considered to be an adaptation in support of their advanced flight abilities. Here, we show that the immense processing speed of the flies' photoreceptors plays a crucial role in mate recognition. RESULTS: Video-recording wing movements of abdomen-mounted common green bottle flies, Lucilia sericata, under direct light at 15,000 frames per second revealed that wing movements produce a single, reflected light flash per wing beat...

The present study examined the relations between sociosexuality and the desirability and the use of innocuous, direct, and cute-flippant opening lines. A total of 216 women rated the desirability of each type of opening line and answered the revised Sociosexual Orientation Inventory (SOI-R). A total of 198 men reported the use of types of opening lines and answered the SOI-R. The desirability of cute-flippant lines, which were the least preferred lines, was positively related to sociosexuality, while the use of cute lines was not associated with sociosexuality...

The EMPA-REG OUTCOME and the LEADER trials have revealed a new era in the management of type 2 diabetes. The SGLT2 inhibitor empagliflozin demonstrated a lower rate of the primary composite outcome of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke compared to placebo. Liraglutide, a GLP-1 analogue, succeeded to demonstrate reduction on a composite outcome including first occurrence of cardiovascular death, nonfatal myocardial infarction or non-fatal stroke. These two medications act through different mechanisms and has consequently shown different patterns of cardiovascular benefit...

Anoctamin (ANO)/TMEM16 proteins exhibit diverse functions in cells throughout the body and are implicated in several human diseases. Although the founding members ANO1 (TMEM16A) and ANO2 (TMEM16B) are Ca2+ -activated Cl- channels, most ANO paralogs are Ca2+ -dependent phospholipid scramblases that serve as channels facilitating the movement (scrambling) of phospholipids between leaflets of the membrane bilayer. Phospholipid scrambling significantly alters the physical properties of the membrane and its landscape and has vast downstream signaling consequences...

Édouard Manet (1832-1883) is considered the 'father' of Impressionism and even of XXth century modern art. Manet's genius involved getting away from the classical narrative or historical topics and replacing them by the banality of daily life. Technically, he erased volumes into flat two-dimensional coloured planes, and distorted conventional perspective with often gross brushstrokes intentionally giving an 'unfinished' aspect to the work. It is little known that Manet had a very painful second part of his life, due to excruciating limb and chest pains, which developed in parallel with proprioceptive ataxia and gait imbalance...

INTRODUCTION:  Beginning in 2015, Zika virus rapidly spread throughout the Americas and has been linked to neurological and autoimmune diseases in adults and babies. Developing accurate tools to anticipate Zika spread is one of the first steps to mitigate further spread of the disease. When combined, air traffic data and network simulations can be used to create tools to predict where infectious disease may spread to and aid in the prevention of infectious diseases. Specific goals were to: 1) predict where travelers infected with the Zika Virus would arrive in the U...

OBJECTIVE: This study examined whether people with moderate-severe traumatic brain injury (TBI) display a specific or a general impairment in emotion recognition compared with matched controls, whether these deficits might be accounted for by deficits in other cognitive processes, and whether emotion recognition predicts social functioning following TBI. PARTICIPANTS: Thirty-two participants with TBI and 32 matched controls took part in this study. DESIGN: Participants completed the Complex Audio-Visual Emotion Assessment Task (CAVEAT), a novel measure of emotion recognition, alongside measures of neuropsychological functioning...

AIM: The aim of this study was to explore the links between pubertal maturation, physical self-esteem and sexuality in adolescence, differentiating between boys and girls. METHOD: The sample was comprised of 312 French secondary school children (seventh and ninth grades); 52.6 % (n=164) of whom were girls. Participants answered three self-evaluation questionnaires: the scale of sexuality (interests, emotions, relationships: IERS) in prime adolescence (12 to 15 years); (b) the self-administered rating scale for pubertal development and (c) the Physical Self-Description Questionnaire (PSDQ)...
