Department of Psychology, Louisiana State University, 236 Audubon Hall, Baton Rouge, LA 70803, USA. Electronic address:

Sexual minority women (SMW) report greater rates of cannabis use. Posttraumatic stress disorder (PTSD) symptom severity is related to greater cannabis use among SMW, and it is theorized that this is due to SMW using cannabis in an attempt to manage negative affectivity associated with PTSD symptoms. However, this is the first known study to test this hypothesis. Read More

Inserm U1016, Institut Cochin, Paris, France.

Plasmodium falciparum gametocytes, the sexual stages responsible for malaria parasite transmission, develop in the human bone marrow parenchyma in proximity to the erythroblastic islands. Yet, mechanisms underlying gametocytes interactions with these islands are unknown. Here, we have investigated whether gametocyte-infected erythrocytes (GIE) adhere to erythroid precursors, and whether a putative adhesion may be mediated by a mechanism similar to the adhesion of erythrocytes infected with P.

Resilience and Poly-Victimization among Two Cohorts of Norwegian Youth.

Int J Environ Res Public Health 2018 Dec 13;15(12). Epub 2018 Dec 13.

Department of Psychology, University of Oslo, PB 1072 Blindern, N-0316 Oslo, Norway.

Previous research shows that there is a significant and positive relationship between being a victim of violence and experiencing high levels of psychological problems among young people. Conversely, resilience is negatively associated with psychological problems among young people in general, and this negative association is particularly strong among victims of violence. Our study examines resilience among young people (aged ≥ 18 years) who reported being victims of multiple forms of violence during childhood and adolescence using data from two national youth surveys administered in Norway in 2007 ( = 7033) and 2015 ( = 4531), respectively.

The selective serotonin reuptake inhibitor fluoxetine has been used for the treatment of depression. Although sexual disorders have been reported in male patients, few studies have demonstrated the fluoxetine effect on the reproductive histophysiology, and the target of this antidepressant in testes is unknown.

Wolbachia has deeply shaped the ecology and evolution of many arthropods, and interactions between the two partners are a continuum ranging from parasitism to mutualism. Non-dispersing queens of the termite Cavitermes tuberosus are parthenogenetically produced through gamete duplication, a mode of ploidy restoration generally induced by Wolbachia. These queens display a bacteriome-like structure in the anterior part of the mesenteron. Read More

Department of Psychology, University of Bologna, Bologna, Italy.

Aim And Objectives: To develop and initially validate the Positive Sexuality Scale (PSS) to assess adult female positive sexuality.

Background: While traditional approaches focus on negative sexual experiences and sexual dysfunctions, within the positive psychology framework positive sexuality is a subjective experience of happiness and fulfillment with one's sexual expression, which contributes to well-being. No measure exists that specifically measures adult female positive sexuality and can be confidently used with women of any fertility/childlessness status. Read More

Centre for Evolutionary Biology, School of Biological Sciences, The University of Western Australia, Crawley.

The social environment is expected to have substantial effects on behavior, and as a consequence its heritability and evolvability. We investigated these effects by exposing Australian field crickets (Teleogryllus oceanicus) to either silence or recordings of male acoustic sexual signals. We used a combined pedigree and full-sib/half-sib breeding design to estimate the repeatability, heritability, and evolvability of behaviors related to boldness, exploration, and activity. Read More

Department of Physiology and Anatomy, University of North Texas Health Science Center, Fort Worth, Texas, USA.

Epidemiological studies demonstrate disparities between men and women in cardiovascular disease prevalence, clinical symptoms, treatments, and outcomes. Enrollment of women in clinical trials is lower than men, and experimental studies investigating molecular mechanisms and efficacy of certain therapeutics in cardiovascular disease have been primarily conducted in male animals. These practices bias data interpretation and limit the implication of research findings in female clinical populations. Read More

Ecological differentiation facilitates fine-scale coexistence of sexual and asexual Boechera.

Department of Biology, Duke University, Box 90338, Durham, North Carolina, 27708, USA.

Premise Of The Study: Ecological differentiation (ED) between sexual and asexual organisms may permit the maintenance of reproductive polymorphism. Several studies of sexual/asexual ED in plants have shown that the geographic ranges of asexuals extend beyond those of sexuals, often in areas of higher latitude or elevation. But very little is known about ED at fine scales, wherein coexistence of sexuals and asexuals may be permitted by differential niche occupation. Read More

This study characterizes for the first time the distribution and co-existence patterns of calbindin (CB), calretinin (CR) and parvalbumin (PV) in the female and male guinea pig preoptic area (POA) during brain development, using immunohistochemistry and qPCR techniques. The results show that the prenatal development of the guinea pig POA takes place in elevated levels of CB and CR immunoreactivity with the peak at embryonic day 50 (E50) and generally in newborns both these proteins reach an adult-like pattern of immunoreactivity, contrary to PV which appears later, peaks at postnatal day 10 (P10), and stabilizes at P20. CB and CR have also overlapping distributions which differed from that of PV, and much higher expressions at mRNA and protein levels. Read More

Maternal body mass index and smoking during pregnancy do not affect the proportional sexual dimorphism for birth weight- an analysis of the German Perinatal Survey.

Anthropol Anz 2018 Dec 14. Epub 2018 Dec 14.

Division of Preventive Medicine, Department of Medicine, University of Alberta, Edmonton, Alberta, Canada.

Male sex has been reported as a risk factor for perinatal mortality. It can be hypothesized that smoking during pregnancy and low maternal pre-pregnancy body mass index (BMI) would lead to a higher proportion of growth restricted male compared to female newborns. The objective of the study was to analyze sex-specific differences in birth weight related to smoking and maternal BMI. Read More
