Pheromones are crucial for eliciting innate responses and inducing social and sexual behaviors in mammals. The vomeronasal receptor 1 genes, V1Rs, encode members of a pheromone receptor family that are mainly expressed in the vomeronasal organ (VNO). The V1R family shows extraordinary variety in gene number among vertebrates owing to successive gene gains and losses during evolution. Such diversity is believed to reflect a degree of dependence on the VNO. We investigated V1R evolution in primate lineages closely related to humans because these VNOs show a trend toward degeneration...

R-spondin 1 (Rspo1) is a potential female-determining gene in mammals that could regulate the Wnt/β-catenin signaling pathway. The deletion of Rspo1 causes sex reversal in females. To investigate sexual determination and differentiation, we cloned and analyzed the Rspo1 gene in Cynoglossus semilaevis. Phylogenetic and gene structure analyses revealed that Rspo1 gene exhibited high sequence conservation and contained an N-terminal signal peptide, two furin-like cysteine-rich domains (FU1 and FU2), a thrombospondin type 1 repeat, and a C-terminal region enriched with basic charged amino acids...

Plasmodium mature sexual cycle occurs in the vector mosquitoes and ensures the transmission to a new host. Gametogenesis takes place within minutes in the vector midgut. Gametocytes have to complete a deep nuclear reorganization, quick differentiation, and in the case of male gametocytes, intracytoplasmic flagellum assembly that results in free-swimming microgametes required for macrogamete fertilization. In efforts to improve our knowledge of molecular mechanisms involved in gamete morphogenesis, we carried out a nanoLC/MSMS based quantitative proteomic analysis throughout the xanthurenic acid-induced gametogenesis of the rodent parasite P...

PURPOSE: Substance use has been linked to the sexual transmission of HIV among gay, bisexual, and other men who have sex with men (MSM) across the lifespan. Among older, HIV-positive, MSM populations, cognitive dysfunction associated with age and HIV disease progression also may play a role in sexual risk-taking. People aged 50 years and older represent a growing proportion of the overall HIV-positive population. This study aimed to explore relationships between substance use and cognitive function, and their impact on condomless anal sex (CAS) among HIV-positive gay, bisexual, and other MSM aged 50 years and older...

OBJECTIVE: Event centrality, or the extent to which traumatic events are perceived to be integral to one's life, has been found to be predictive of trauma-related symptoms, such as posttraumatic stress disorder (PTSD) and depression. Less research has been devoted to whether event centrality is related to adaptive outcomes, such as posttraumatic growth (PTG) and resiliency, and psychological well-being (PWB) has not been investigated. Given the unique circumstances of different types of traumas, the relationship between event centrality and posttrauma functioning may differ by the type of trauma experienced...

Despite the high prevalence of hyperprolactinemia in patients receiving antipsychotic medications, its side effects are often neglected. In patients receiving risperidone, the incidence of menstrual abnormalities is relatively small. Our patient was a 44-year-old, Haitian female whose total course of hospitalization was nine months, during most of which she remained floridly psychotic with low cognitive function with waxing and waning symptoms. She developed hyperprolactinemia and amenorrhea on risperidone...

Climate change and the resulting changes in air temperature are known to have a major influence on most animals, especially poikilothermic insects, because they depend on the high enough temperatures to function. Previous studies have shown that various signals can be affected by changes in temperature. However, research into the effect of temperature on mating signals and subsequently communication between mates and on female choice is still rare. In the red mason bee, Osmia bicornis, which emerges early in spring and is therefore subject to extensive temperature changes, females choose suitable males based on, among other criteria, their thorax vibrations and odor...

The parotoid macroglands of bufonid anurans store (and can expel) large volumes of toxic secretions and have attracted detailed research. However, toxins also are stored in smaller glands that are distributed on the limbs and dorsal surface of the body. Female and male cane toads (Rhinella marina) differ in the location of toxin-storage glands and the extent of glandular structures. Female toads store a larger proportion of their toxins in the parotoids than males as well as (to a lesser extent) in smaller glands on the forelimbs...

During a survey of Phytophthora diversity in natural ecosystems in Taiwan six new species were detected. Multigene phylogeny based on the nuclear ITS, ß-tubulin and HSP90 and the mitochondrial cox1 and NADH1 gene sequences demonstrated that they belong to ITS Clade 7a with P. europaea, P. uniformis, P. rubi and P. cambivora being their closest relatives. All six new species differed from each other and from related species by a unique combination of morphological characters, the breeding system, cardinal temperatures and growth rates...

Plants have evolved two tiers of immune receptors to detect infections: cell surface-resident pattern recognition receptors (PRRs) that sense microbial signatures and intracellular nucleotide-binding domain leucine-rich repeat (NLR) proteins that recognize pathogen effectors. How PRRs and NLRs interconnect and activate the specific and overlapping plant immune responses remains elusive. A genetic screen for components controlling plant immunity identified ANXUR1 (ANX1), a malectin-like domain-containing receptor-like kinase, together with its homolog ANX2, as important negative regulators of both PRR- and NLR-mediated immunity in Arabidopsis thaliana...

BACKGROUND: Women with endometrial cancer (EC) are the second largest population of female cancer survivors in the United States. However, the outcomes of EC survivors, from the patient perspective, are not well-understood. Therefore, we conducted a systematic review of patient-reported outcomes (PROs) following an EC diagnosis. METHODS: We searched MEDLINE, EMBASE, Scopus, CINAHL, and reference lists to identify published observational studies that examined PROs among women with EC...

OBJECTIVES: Sexual dysfunction occurs commonly in individuals with end-stage renal disease. Chronic renal failure as well as the treatments used for it generally has a negative impact on sexual function with a subsequent increase in the risk of depression. There is scarcity of published data on female sexual dysfunction and the degree of improvement in patients on hemodialysis (HD) and transplant (Tx) recipients. The aim of this study was to compare the sexual function and degree of depression in HD and Tx patients with control group...

BACKGROUND: Cancer-related sexual dysfunction has been reported among adolescents and young adults (AYAs); however, its prevalence over time has not been examined. This longitudinal study investigated sexual dysfunction in AYAs over the course of 2 years after the initial diagnosis. METHODS: Young adult patients (18-39 years old) completed the Medical Outcomes Study Sexual Functioning Scale within the first 4 months of their diagnosis (n = 123) and again 6 (n = 107) and 24 months later (n = 95)...

Current models of sexual functioning imply an important role for both automatic and controlled appraisals. Accordingly, it can be hypothesized that erectile dysfunction may be due to the automatic activation of negative appraisals at the prospect of sexual intercourse. However, previous research showed that men with sexual dysfunction exhibited relatively strong automatic sex-positive instead of sex-negative associations. This study tested the robustness of this unexpected finding and, additionally, examined the hypothesis that perhaps more specific sex-failure versus sex-success associations are relevant in explaining sexual dysfunction and distress...

Phthalates are widely used as plasticizers that influence sexual and reproductive development. Here, we investigated whether di-(2-ethylhexyl) phthalate (DEHP) affects macrophage polarization that are associated with tumor initiation and progression. No changes were observed in LPS- or ConA-stimulated in vitro spleen B or T cell proliferation for 48 h, respectively. In contrast, macrophage functions were inhibited in response to DEHP for 12 h as judged by LPS-induced H2O2 and NO production and zymosan A-mediated phagocytosis...

The comorbidity between male genital pain and sexual dysfunction is highly prevalent. Previous studies have indicated that men with genital pain share some cognitive characteristics with men experiencing other sexual dysfunctions. However, there is little information on the role of these cognitive factors in understanding the relationship between pain intensity and sexual functioning. This study aims to test if negative sexually-related thoughts mediate the relationship between pain intensity and sexual functioning in men with genital pain...

INTRODUCTION: For dorsal onlay graft placement, unilateral urethral mobilization is less invasive than standard circumferential urethral mobilization. Apart from success in terms of patency of urethra, other issues like sexual function, overall quality of life and patient satisfaction remain important issues while comparing outcomes of urethroplasty. AIM: To prospectively compare the objective as well as subjective outcomes of two approaches. MATERIALS AND METHODS: Between July 2011 and January 2015, 136 adult males having anterior urethral stricture with urethral lumen ≥ 6 Fr...
