In ectotherms, lower temperatures in high-latitude environments would theoretically reduce the annual growth rates of individuals. If slower and resultant smaller body size fitness, individuals higher latitudes may evolve compensatory responses. Two alternative models such latitudinal compensation are possible: Model I: thermal reaction norms for be horizontally shifted to a range temperatures, or II: vertically so that can grow faster across all temperatures. I is expected when wild only...
Skin trait variation impacts quality-of-life, especially for females from the viewpoint of beauty. To investigate genetic related to these traits, we conducted a GWAS various skin phenotypes in 11,311 Japanese women and identified associations age-spots, freckles, double eyelids, straight/curly hair, eyebrow thickness, hairiness, sweating. In silico annotation with RoadMap Epigenomics epigenetic state maps colocalization analysis GTEx Project eQTL signals provided information about tissue...
This study aimed to investigate the relationship between psychosocial factors and andropause symptoms among Japanese men in an internet-based cross-sectional study. We conducted 2024, named Men’s health Andropause Related Symptoms (J-MARS) Data on demographics, medical history, symptoms, lifestyles (physical activity, insomnia, height, weight, smoking drinking habits), psychological distress were collected from 1,489 aged 20–69 years who participated J-MARS measured using Aging Males’ (AMS)...
Food allergy is an increasingly important health problem in the world. Several genome-wide association studies (GWAS) focused on European ancestry samples have identified food allergy-specific loci HLA class II region. We conducted GWAS of self-reported reactivity with common foods using data from 11011 Japanese women and shrimp peach HLA-DR/DQ gene region tagged by rs74995702 (P = 6.30 × 10-17, OR 1.91) rs28359884 2.3 10-12, 1.80), respectively. After imputation a population-specific...
Sexual dimorphism can evolve when males and females differ in phenotypic optima. Genetic constraints can, however, limit the evolution of sexual dimorphism. One possible constraint is derived from alleles expressed both sexes. Because share most their genome, shared with different fitness effects between sexes are faced intralocus conflict. Another potential genetic correlations developmental stages. Sexually dimorphic traits often favoured at adult stages, but selected against as juvenile,...
Medaka, Oryzias latipes complex, display sexual dimorphisms in anal- and dorsal-fin lengths that suggest females may prefer males with longer fins. However, female preference for anal and/or dorsal fins has not yet been described the medaka. One reason previous studies have investigated this relationship be because variations male fin within a single population are too small to experimentally detect preference. In study, we artificially crossed individuals from two wild populations (Aomori...
Heterochrony is believed to have played important roles in macroevolutionary morphological changes. However, few studies focused on intraspecific heterochrony, although interspecific differences ultimately originated from variation within ancestral species. We demonstrated heterochrony fin development between two latitudinal populations of the medaka, Oryzias latipes. Comparisons length (anal and dorsal) among wild individuals revealed that fins are shorter with respect body northern...
Maternal mental illnesses during early postpartum may be caused by lack of the coparenting relationship parents share and cooperate regarding child-rearing. This study clarifies association negative health mothers at one three months after childbirth. conducted a secondary analysis data from an intervention wherein 24 rearing their first child with cohabitant (husband/partner) participated. was evaluated using Edinburgh Postnatal Depression Scale to determine depressive symptoms...
Abstract Objectives Women working in the medical field may be at risk for pelvic floor dysfunction due to high physical activity levels leading increased abdominal pressure; however, actual situation remains unknown. This study aimed clarify prevalence of symptoms and its associated factors among Japanese women field. Methods A cross‐sectional was conducted female employees a public hospital Japan from July August 2020. Participants answered web‐based questionnaire. Three types related were...
Having and raising children can be a source of joy for parents. However, the transition to parenthood is associated with certain degree strain stress, couple relationship quality often declines during transition. Coparenting, shared responsibility childrearing, benefits both parents an important aspect parenthood. In this quasi-experimental study, we aimed develop education program in Japan that focuses on coparenting among couples expecting their first child. Twenty-one healthy voluntarily...
Traits involved in reproduction evolve rapidly and show great diversity among closely related species. However, the genetic mechanisms that underlie diversification of courtship traits are mostly unknown. Japanese medaka fishes (Oryzias latipes) use anal fins to attract females grasp during courtship; males have longer with male-specific ossified papillary processes on fin rays. morphology varies between populations: southern populations tend more than northern populations. In present study,...
Previous studies have proposed that pelvic misalignment may be associated with stress urinary incontinence through a decrease in the contractile function of floor muscles; however, this relationship remains unclear. This study aimed to clarify between low back pain, an indication misalignment, and at 3 months postpartum. We conducted cross-sectional women who gave birth full-term babies July 2008 2009. Stress was defined as leakage when coughing, sneezing, or exercising. Low pain ribs...
Abstract Aim To describe the characteristics of objectively measured physical activity (PA) during 2nd and 3rd trimesters pregnancy using a accelerometer. Methods This was longitudinal observational study wherein PA in pregnant women for seven consecutive days accelerometer (Silmee W10, TDK, Japan). Results A total 34 primiparous were examined. There no statistically significant difference amount pregnancy. Sub‐group analysis demonstrated that full‐time housewife group increased...
Physical activity (PA) during pregnancy is associated with maternal benefits. Therefore, innovative strategies that promote PA are needed. This study investigated the acceptability and feasibility of a sedentary behavior (SB) reduction program pregnancy. The employed semi-experimental research design using historical control subjects. intervention group consisted individual face-to-face guidance, automatic alerts SB from wearable devices, self-monitoring patterns, 20 gestation weeks to...
Sex steroids mediate the expression of sexual dimorphism during ontogeny, and populations that differ in magnitudes may accordingly ontogenetic patterns their sex steroid levels. The medaka, Oryzias latipes species complex, shows geographic variation magnitude with respect to lengths anal dorsal fins; is greater low-latitude than high-latitude populations. However, differences dynamics steroids, its interpopulation variation, have not been examined.We measured testosterone (T), estradiol-17β...
Abstract Intrinsic growth rates often vary greatly among populations within a single species, implying that trade‐offs with fast are present. It has been hypothesized such trade‐off exists between rate and development rate. Growth‐development have considered from observations of negative correlation populations. In this study, we examined not only interpopulation but also intrapopulation correlations in fish Oryzias latipes . Rearing experiments revealed larvae high‐latitude population grew...
Working pregnant women often need to adjust their physically demanding jobs for a healthy pregnancy. However, uncertainty about the extent of these adjustments can hinder effectiveness.
