This study investigates the transnational mobility of Iranian women pursuing higher education in South Korea, focusing on their motivations, adaptation, and postgraduation trajectories. Drawing on the influence of the Korean Wave since the 2000s, it examines how popular culture, gender constraints in Iran, and migration aspirations intersect. Despite their initial attraction to Korea’s global image, many face cultural barriers, discrimination, and restrictive visa systems that limit settlement opportunities. Consequently, some seek “onward migration” to third countries such as Canada or Germany. By situating these experiences within broader Iranian migration dynamics, the study highlights gendered dimensions of educational migration and the policy limitations shaping Iranian students’ transnational mobility.

This article explores the potential barriers for emerging composers to constructing and maintaining a career in the field of composition in Scotland, viewed through the lens of both those early in their careers and the experience of others who have worked professionally for many years. Thirty-nine composers responded to a survey that highlighted the role of educational mentoring, the need for monetary stability and the challenges faced by female and older emerging composers. The professional lives of current Scottish composers have been seldom studied, and the purpose of this investigation is to explore, inform and provide suggestions for future consideration.

Since the beginning of mass vaccination campaign for COVID-19 in Italy (December 2020) and following the rapidly increasing vaccine administration, sex differences have been emphasized. Nevertheless, incomplete and frequently incoherent sex-disaggregated data for COVID-19 vaccinations are currently available, and vaccines clinical studies generally do not include sex-specific analyses for safety and efficacy. We looked at sex variations in the COVID-19 vaccine’s effectiveness against infection and severe disease outcomes. We conducted a nationwide retrospective cohort study on Italian population, linking information on COVID-19 vaccine administrations obtained through the Italian National Vaccination Registry, with the COVID-19 integrated surveillance system, held by the Istituto Superiore di Sanità. The results showed that, in all age groups, vaccine effectiveness (VE) was higher in the time-interval ≤120 days post-vaccination. In terms of the sex difference in vaccination effectiveness, men and women were protected against serious illness by vaccination in a comparable way, while men were protected against infection to a somewhat greater extent than women. To fully understand the mechanisms underlying the sex difference in vaccine response and its consequences for vaccine effectiveness and development, further research is required. The sex-related analysis of vaccine response may contribute to adjust vaccination strategies, improving overall public health programmes.

This review discusses epigenetic mechanisms and the relationship of infertility in men and women in relation to parameters pertaining to nutrition. The prevalence of infertility worldwide is 8–12 %, and one out of every eight couples receives medical treatment. Epigenetic mechanisms, aging, environmental factors, dietary energy and nutrients and non-nutrient compounds; more or less energy intake, and methionine come into play in the occurrence of infertility. It also interacts with vitamins B12, D and B6, biotin, choline, selenium, zinc, folic acid, resveratrol, quercetin and similar factors. To understand the molecular mechanisms regulating the expression of genes that affect infertility, the environment, the role of genotype, age, health, nutrition and changes in the individual's epigenotype must first be considered. This will pave the way for the identification of the unknown causes of infertility. Insufficient or excessive intake of energy and certain macro and micronutrients may contribute to the occurrence of infertility as well. In addition, it is reported that 5–10 % of body weight loss, moderate physical activity and nutritional interventions for improvement in insulin sensitivity contribute to the development of fertility. Processes that pertain to epigenetics carry alterations which are inherited yet not encoded via the DNA sequence. Nutrition is believed to have an impact over the epigenetic mechanisms which are effective in the pathogenesis of several diseases like infertility. Epigenetic mechanisms of individuals with infertility are different from healthy individuals. Infertility is associated with epigenetic mechanisms, nutrients, bioactive components and numerous other factors.

Smoking has dangerous and sometimes irreversible effects on various body tissues, including the reproductive system. We conducted this research to determine the in vivo effects of cigarette smoke condensate (CSC) on reproduction in mice. In this experimental in vivo study, 32 male and female NMRI mice were divided into four groups. The mice were injected with CSC (CSC-1R3F) for 28 days. The mice were mated 1 day after the last injection and observed daily for 1 week for the presence of a vaginal plug to track mating. We evaluated mating success rate, and sperm and oocyte quality, pregnancy outcome, childbearing status, and in vitro fertilization (IVF). The results showed a decrease in successful mating in female mice that received the CSC injections. CSC significantly influenced the number of offspring born to males. When the CSC was injected into male mice, there was a significant increase in the number of offspring compared with the group in which only the females received CSC injections. According to the results, there was a negative effect of CSC on morphological parameters in male and female mice. Also, successful IVF after exposure to CSC was significantly decreased in the female mice treated group. The results indicated that CSC significantly affected the number of offspring and fecundity success in females.

Although research on the experiences of females on the autism spectrum is still developing, it is becoming increasingly apparent that their experiences are not comparable to their male counterparts. This scoping review aimed to collate research related to the peer interaction experiences of school-aged girls on the autism spectrum from their perspective. A database and journal search (2010–2020) found 21 studies. Key findings indicated that although school-aged girls on the autism spectrum generally desired friendship, they faced diverse peer interaction difficulties, including making and maintaining friendships, peer victimisation, and rejection. Given these challenges, appropriate peer interaction supports and further research into the complexities of their peer interaction experience is needed.

Female adolescents have a greatly increased risk of depression starting at puberty, which continues throughout the reproductive lifespan. Sex hormone fluctuation has been highlighted as a key proximal precipitating factor in the development of mood disorders tied to reproductive events; however, hormone-induced affective state change is poorly understood in the pubertal transition. The present study investigated the impact of recent stressful life events on the relationship between sex hormone change and affective symptoms in peripubertal female participants. Thirty-five peripubertal participants (ages 11–14, premenarchal, or within 1 year of menarche) completed an assessment of stressful life events, and provided weekly salivary hormone collections [estrone, testosterone, dehydroepiandrosterone (DHEA)] and mood assessments for 8 weeks. Linear mixed models tested whether stressful life events provided a context in which within-person changes in hormones predicted weekly affective symptoms. Results indicated that exposure to stressful life events proximal to the pubertal transition influenced the directional effects of hormone change on affective symptoms. Specifically, greater affective symptoms were associated with increases in hormones in a high stress context and decreases in hormones in a low stress context. These findings provide support for stress-related hormone sensitivity as a diathesis for precipitating affective symptoms in the presence of pronounced peripubertal hormone flux.

Coronavirus disease, one of the most disastrous epidemics, has caused a worldwide crisis, and the containment measures applied to decelerate the progression of the pandemic can increase the risk of obsessive-compulsive disorder (OCD). Identifying vulnerable groups in this area can lead us to better resource expenditure, and therefore, this systematic review aims to make a comparison between males and females to determine which of the two groups was most affected by the COVID-19 pandemic regarding OCD. Also, a meta-analysis was designed to investigate the prevalence of OCD during the COVID-19 pandemic. A comprehensive search was conducted among three databases (Medline, Scopus, Web of Science) until August 2021 which resulted in 197 articles, and 24 articles met our inclusion criteria. Overall, more than half of the articles stated the role of gender in OCD during the COVID-19 pandemic. Several articles emphasized the role of the female gender, and some others the role of the male gender. The meta-analysis revealed a 41.2% overall prevalence of OCD during the COVID pandemic and 47.1% and 39.1% OCD prevalence for female and male genders respectively. However, the difference between the two genders was not statistically significant. Generally, it seems that females are at greater risk of OCD during the COVID-19 pandemic. In the following groups, the female gender may have acted as a risk factor: under-18 years students, hospital staff, and the studies in the Middle East. In none of the categories, male gender was clearly identified as a risk factor.

Female laboratory rats (Rattus norvegicus; Wistar, Alderley Park) were housed as singletons or groups of three in units of two cages. Units were divided by different types of barrier which allowed varying degrees of social contact across the barrier. Singletons were established either with another singleton on the other side of the barrier or with a group of three as neighbours. Single-housing among females had markedly less effect on time budgeting and pathophysiological measures than among males in a similar, earlier study. In particular, singletons showed a less marked increase in self-directed behaviours, particularly tail chasing, and a smaller reduction in undirected movement around the cage. The smaller reduction in mobility may reflect a greater tendency for singly housed females to attempt escape. Females generally showed much higher levels of escape-oriented behaviours than males and up to a threefold increase in such behaviours when housed singly. Differences in time budgeting and in the apparent significance of social separation between the sexes can be interpreted in terms of differences in socio-sexual strategy and potential mating opportunity, with singleton males responding to their cage as a territory, but singleton females seeking to re-establish social contact. Such an interpretation is consistent with the effects of barrier type on behaviour in singleton females, in which time spent in escape-oriented behaviours reflected the extent to which the barrier facilitated, or frustrated, contact with neighbours.
