REVIEW
Georgia Gerogianni, Anastasios Kouzoupis, Eirini Grapsa
Depression in dialysis populations is affected by co-morbid diseases, such as cardiovascular disease, diabetes, and immune dysfunction, and it also includes high suicide risk and frequent hospitalizations. Depressive disorders have a close association with malnutrition and chronic inflammation, as well as with cognitive impairment. Impaired cognitive function may be manifested as low adherence to dialysis treatment, leading to malnutrition. Additionally, chronic pain and low quality of sleep lead to high rates of depressive symptoms in haemodialysis patients, while an untreated depression can cause sleep disturbances and increased mortality risk...

The aim of the present study was to investigate the effects of a strategy for extending pro-oestrus (the interval between luteolysis and ovulation) in an oestrus synchronisation protocol (named J-Synch) in beef heifers on follicular growth, sexual steroid concentrations, the oestrogen receptor ERα and progesterone receptors (PR) in the uterus, insulin-like growth factor (IGF) 1 and pregnancy rates. In Experiment 1, heifers treated with the new J-Synch protocol had a longer pro-oestrus period than those treated with the conventional protocol (mean (±s...

REVIEW
Samantha Lawson, Ashley Sacks
Pelvic floor dysfunction is defined as abnormal function of the pelvic floor and includes conditions that can have significant adverse impacts on a woman's quality of life, including urinary incontinence (stress, urge, and mixed), fecal incontinence, pelvic organ prolapse, sexual dysfunction, diastasis recti abdominis, pelvic girdle pain, and chronic pain syndromes. Women's health care providers can screen for, identify, and treat pelvic floor dysfunction. This article examines the case of a woman with multiple pelvic-floor-related problems and presents the evidence for the use of pelvic floor physical therapy (PFPT) for pregnancy-related pelvic floor dysfunction...

Idiopathic hypogonadotropic hypogonadism (IHH) is characterized by low levels of gonadotropins and delayed or absent sexual development. Most of the patients are diagnosed in late adolescence or early adulthood. Determining the diagnosis of IHH in prepubertal patients can be challenging. Making a timely, correct diagnosis has important clinical implications. Here we aimed to identify the genetic cause of IHH in three prepubertal siblings from a Chinese Han family and give appropriate treatment advice. Using whole exome sequencing (WES), we identified a novel homozygous GNRHR mutation (NM_000406; c...

Although neonatal exposure to estrogen or estrogenic compounds results in irreversible changes in the brain function and reproductive abnormalities during adulthood but the underlying mechanisms are still largely unknown. The present study has attempted to compare the protein profiles of sexually dimorphic brain regions of adult female rats which were exposed to estradiol- 17β during neonatal period. The total proteins extracted from pre-optic area (POA), hypothalamus, hippocampus and pituitary of control and neonatally E2 treated female rats was subjected to 2D-SDS-PAGE and differentially expressed proteins were identification by MALDI TOF/TOF-MS...

BACKGROUND: Patients on androgen deprivation therapy (ADT), a common treatment for prostate cancer, report significant declines in quality of life and detrimental impact on their intimate relationships. ADT depresses a man's testosterone to castrate levels, leading to declines in sexual function, and changes in mood. These changes can have profound impact on couples' intimate relationships. METHOD: Patients undergoing ADT, and their consenting partners, were followed on a variety of outcomes relating to mood, sexual changes, and relational intimacy...

BACKGROUND: Trichogrammatids are minute parasitoid wasps that develop within other insect eggs. They are less than half a millimeter long, smaller than some protozoans. The Trichogrammatidae are one of the earliest branching families of Chalcidoidea: a diverse superfamily of approximately half a million species of parasitoid wasps, proposed to have evolved from a miniaturized ancestor. Trichogramma are frequently used in agriculture, released as biological control agents against major moth and butterfly pests...

BACKGROUND: Many young men who have sex with men (YMSM) are reluctant to seek health services and trust local physicians. Online information seeking may encourage YMSM to identify and see trustworthy physicians, obtain sexual health services, and obtain testing for sexually transmitted infections (STIs). This study examined online STI information seeking behaviors among Chinese YMSM and its association with offline physician visits. METHODS: We conducted a nationwide online survey among YMSM through WeChat, the largest social media platform in China...

Bruno Campos, Danielle Fletcher, Benjamín Piña, Romà Tauler, Carlos Barata
BACKGROUND: Unravelling the link between genes and environment across the life cycle is a challenging goal that requires model organisms with well-characterized life-cycles, ecological interactions in nature, tractability in the laboratory, and available genomic tools. Very few well-studied invertebrate model species meet these requirements, being the waterflea Daphnia magna one of them. Here we report a full genome transcription profiling of D. magna during its life-cycle. The study was performed using a new microarray platform designed from the complete set of gene models representing the whole transcribed genome of D...

Mothers with a substance use disorder (SUD) are at risk for maladaptive parenting practices, and have heightened likelihood of having experienced childhood adversity themselves. In addition, parental reflective functioning (PRF), a capacity underlying sensitive caregiving, is often low in mothers with SUD. This study examines the relationship between PRF and aversive (emotional, physical, sexual abuse and neglect) and adaptive (safety and competence) experiences, in different developmental phases (early childhood, latency, and adolescence) in mothers with a SUD...

PURPOSE OF REVIEW: Treatment of anterior urethral stricture disease (USD) has shifted from endoscopic approaches to urethroplasty with significantly higher success rates among reconstructive urologists. This academic stance has led to a critical evaluation of "success" and developing disease-specific instruments to assess surgical outcomes focusing on patients' satisfaction rather than the historical goal of avoiding secondary procedures. RECENT FINDINGS: Many disease non-specific and/or non-validated patient-reported outcome measures (PROMs) have been utilized to evaluate the voiding symptoms and sexual of function of patients after urethroplasty in the literature...

Erectile dysfunction (ED) is caused by microvascular or macrovascular insufficiency in the majority of patients. Recent studies have shown that hyperbaric oxygen therapy (HBOT) can induce angiogenesis in different body organs. The effect of HBOT on the non-surgery-related ED has not been investigated yet. The aim of the current study was to evaluate the effects of HBOT on sexual function and penile vascular bed in non-surgical ED patients. A prospective analysis of patients suffering from chronic ED treated with 40 daily HBOT sessions...

Rashmi Srivastava, Lawrence E Cornett, Chandra Mohini Chaturvedi
Role of estrogen and photoperiod is well-established in avian reproduction. In addition, the distribution and the expression of arginine vasotocin (AVT) and its receptor VT3 to ensure reproductive/breeding conditions in Japanese quail influenced by them has been the main focus of this review. To consider this aspect the mRNA expression of VT3 receptor and its ligand AVT in the shell gland has been emphasized. In birds, AVT performs a dual role as an anti-diuretic hormone and the functions accomplished by oxytocin in mammals...

Leandro Bueno Lima, Fernanda Tais Haubenthal, Marina Augusto Silveira, Tabata Mariz Bohlen, Martin Metzger, Jose Donato, Renata Frazao
A small neuronal subpopulation in the medial nucleus of the amygdala (MeA), expressing the Kiss1 gene, is now considered an important mediator that integrates socio-sexual behavior and odor information in order to modulate the Hypothalamic-Pituitary-Gonadal (HPG) axis. Previous studies demonstrated that exogenous kisspeptin administration or selective activation of Kiss1-expressing neurons in the MeA modulates the onset of puberty, LH secretion and sexual behavior. These functions are supported by the known MeA neuronal connections...

The reproductive endocrine systems are vastly different between male and female. This sexual dimorphism of endocrine milieu originates from sex-specific differentiation of the somatic cells in the gonads during fetal life. The majority of gonadal somatic cells arise from the adrenogonadal primordium. After separation of the adrenal and gonadal primordia, the gonadal somatic cells initiate sex-specific differentiation during gonadal sex determination with the specification of the supporting cell lineages: Sertoli cells in the testis vs...

In this study, methanolic extract of Saraca asoca bark was evaluated for its aphrodisiac potential using male and female Wistar albino rats. Male rats were dosed daily for 54 days at a dose of 100 mg/kg p.o. Sexual activity of male rats was assessed after 14, 28, 42 and 54 days of the study. Male rats were placed in a glass chamber lit with a dim red light (10W) followed by the introduction of sexually receptive female rats in a ratio of 1:1. Improvement in sexual behaviour of male rats was characterised by an increase in both mount frequency and intromission frequency and decrease or reduction in mount latency and intromission latency compared to normal control...

Birgitta Dresp-Langley, Adam Reeves
Colour information not only helps sustain the survival of animal species by guiding sexual selection and foraging behaviour but also is an important factor in the cultural and technological development of our own species. This is illustrated by examples from the visual arts and from state-of-the-art imaging technology, where the strategic use of colour has become a powerful tool for guiding the planning and execution of interventional procedures. The functional role of colour information in terms of its potential benefits to behavioural success across the species is addressed in the introduction here to clarify why colour perception may have evolved to generate behavioural success...

REVIEW
Roxanne S Beltran, Jennifer M Burns, Greg A Breed
Birds and mammals have developed numerous strategies for replacing worn feathers and hair. Moulting usually occurs on an annual basis; however, moults that take place twice per year (biannual moults) also occur. Here, we review the forces driving the evolution of various moult strategies, focusing on the special case of the complete biannual moult as a convergence of selection pressures across birds and mammals. Current evidence suggests that harsh environmental conditions or seasonality (e.g. larger variation in temperatures) drive evolution of a biannual moult...
