STUDY QUESTION: Are there significant differences in the ability of X chromosome-bearing (X) spermatozoa and Y chromosome-bearing (Y) spermatozoa to survive incubation under stressful conditions? SUMMARY ANSWER: Y spermatozoa are more vulnerable to stress than their X counterparts depending on culture period and temperature, and show higher expression of apoptotic proteins. WHAT IS KNOWN ALREADY: The primary sex ratio is determined by there being an equal number of spermatozoa carrying X and Y chromosomes...

Conservation and management of migratory species can be complex and challenging. International agreements such as the Convention on Migratory Species (CMS) provide policy frameworks, but assessments and management can be hampered by lack of data and tractable mechanisms to integrate disparate datasets. An assessment of scalloped (Sphyrna lewini) and great (Sphyrna mokarran) hammerhead population structure and connectivity across northern Australia, Indonesia and Papua New Guinea (PNG) was conducted to inform management responses to CMS and Convention on International Trade in Endangered Species listings of these species...

Research studies using existing samples of individuals with autism spectrum disorders have identified differences in symptoms between males and females. Differences are typically reported in school age and adolescence, with similarities in symptom presentation at earlier ages. However, existing studies on sex differences are significantly limited, making it challenging to discern if, how, and at what point in development females with autism spectrum disorder actually exhibit a different behavioral presentation than males...

OBJECTIVE: Individuals with eating disorders (ED), particularly anorexia nervosa (AN), and bulimia nervosa (BN), often wish to reduce their body weight in pursuit of a thin ideal, but no study has examined the relation between desired weight and ED pathology in a clinical population of youth. Given the potential impact of desired weight on normalization of eating patterns and weight restoration, we examined the relation between desired weight and ED pathology in youth with AN or BN. METHODS: Participants were 340 youth presenting to an outpatient ED clinical research program...

People living with HIV in poverty have limited tangible and mental resources coupled with competing demands for these resources. Competing demands require individuals to make choices that may be beneficial to them in the short term but not in the long term. Past research has shown that food insecurity is related to sexual risk behaviors among people living with HIV. Individuals who are food insecure may sell sex in order to obtain food or lack of food may lead to a depletion of mental resources to negotiate safe sex...

BACKGROUND: There is on ongoing debate in the literature regarding the real burden of STIs (sexually transmitted infections) in Western countries and the proper strategies needed to estimate and to prevent them. Our purpose is to present an evidence-based national strategic plan for STI prevention in Israel through assessing the current burden of illness, leading international preventive strategies, and practical policymaking experience. METHODS: Epidemiologic and health policy data on STIs were analyzed from various sources: a) systematic national surveillance data for the years 2002-2014; b) the international scientific literature (published between 2002-16; keywords: Sexually Transmitted Diseases (STD) (or STI) AND prevention AND intervention AND gonorrhea OR chlamydia OR syphilis; c) internal Ministry of Health (MOH) analyses and reports, and d) expert opinion...

BACKGROUND: Many HIV (human immunodeficiency virus) prevention interventions are currently being implemented and evaluated, with little information published on their development. A framework highlighting the method of development of an intervention can be used by others wanting to replicate interventions or develop similar interventions to suit other contexts and settings. It provides researchers with a comprehensive development process of the intervention. OBJECTIVE: The objective of this paper was to describe how a systematic approach, intervention mapping, was used to develop a tailored Web-based intervention to increase condom use among HIV-positive men who have sex with men...

INTRODUCTION: Recent research suggests that anti-bullying laws may be effective in reducing risk of bullying victimization among youth, but no research has determined whether these laws are also effective in reducing disparities in bullying. The aim of this paper was to evaluate the effectiveness of anti-bullying legislation in reducing disparities in sex- and weight-based bullying and cyberbullying victimization. METHODS: Data on anti-bullying legislation were obtained from the U...

BACKGROUND: Individuals with multiple sclerosis (MS) frequently suffer from impaired sensory function, reduced strength and tremor in the upper limbs, which may interfere with upper limb function. However, upper limb impairment in MS is under-recognized and understudied. We aimed to evaluate the prevalence of upper limb impairment in a large sample of persons with MS; the association between upper limb function and employment status in MS; and the frequency of use of assistive devices aimed at addressing upper limb impairments...

BACKGROUND: It is estimated that people with dementia are approximately three times more likely to fracture their hip than sex and age matched controls. A report by the Chartered Society of Physiotherapy found that this population have poor access to rehabilitation as inpatients and in the community. A recent scoping review found a paucity of research in this area, indeed there has been no qualitative research undertaken with physiotherapists. In order to address this evidence gap, the aim of this current study was to explore the experiences of physiotherapists treating this population...

BACKGROUND: Cytoplasmic sex allocation distorters, which arise from cytonuclear conflict over the optimal investment into male versus female reproductive function, are some of the best-researched examples for genomic conflict. Among hermaphrodites, many such distorters have been found in plants, while, to our knowledge, none have been clearly documented in animals. METHODS: Here we provide a quantitative test for cytonuclear conflict over sex allocation in the simultaneously hermaphroditic flatworm Macrostomum lignano...

Interest in quantifying consistent among-individual variation in primate behavior, also known as personality, has grown rapidly in recent decades. Although behavioral coding is the most frequently utilized method for assessing primate personality, limitations in current statistical practice prevent researchers' from utilizing the full potential of their coding datasets. These limitations include the use of extensive data aggregation, not modeling biologically relevant sources of individual variance during repeatability estimation, not partitioning between-individual (co)variance prior to modeling personality structure, the misuse of principal component analysis, and an over-reliance upon exploratory statistical techniques to compare personality models across populations, species, and data collection methods...

BACKGROUND: Sudden unexpected death in epilepsy (SUDEP) is a major cause of death in patients with epilepsy. Several risk factors have been implicated, including early age of onset, tonic-clonic seizures and antiepileptic drugs. However, whether patients who die from SUDEP have a greater frequency of seizures in the few months before death is unclear. We investigated the terminal seizure frequency and its relation to SUDEP among a large group of patients with tonic-clonic seizures in rural West China...
