Switchgrass is a photoperiod-sensitive energy grass suitable for growing in the marginal lands of China. We explored the effects of extended photoperiods of low-irradiance light (7 μmol·m-2·s-1, no effective photosynthesis) on the growth, the biomass dry weight, the biomass allocation, and, especially, the stem digestibility and cell wall characteristics of switchgrass. Two extended photoperiods (i.e., 18 and 24 h) were applied over Alamo. Extended light exposure (18 and 24 h) resulted in delayed heading and higher dry weights of vegetative organs (by 32...

The approach to children with anogenital warts in the context of sexual abuse is a challenge in clinical practice. This study aims to review the current knowledge of anogenital warts in children, the forms of transmission, and the association with sexual abuse and to propose a cross-sectional approach involving all medical specialties. A systematic review of the literature was conducted in Portuguese and English from January 2000 to June 2016 using the ISI Web of Knowledge and PubMed databases. Children aged 12 years or younger were included...

Abortion is a very sensitive issue with relevance to public health; however few clinical or population-based studies have examined induced abortion among drug users. The study aims to evaluate the prevalence of induced abortion and sex-related conditions in an inpatient drug user sample. A cross-sectional design study was conducted in an inpatient addiction treatment unit in São Paulo, Brazil, with a sample of 616 patients, aged 18-75. Sociodemographic data, sexual behavior, and dependence severity were evaluated in relation to induced abortion...

BACKGROUND: Although trafficked women and adolescents are at risk of unprotected or forced sex, there is little research on maternity care among trafficking survivors. We explored health care needs, service use and challenges among women who became pregnant while in the trafficking situation in the United Kingdom (UK) and clinicians' perspectives of maternity care for trafficked persons. METHODS: Cross-sectional survey and qualitative interviews with trafficking survivors recruited from statutory and voluntary sector organisations in England and qualitative interviews with maternity clinicians and family doctors undertaken to offer further insight into experiences reported by these women...

Research has indicated that adult romantic attachment is influential and important to sexual and relationship satisfaction. Sexual desire, although not a direct focus of attachment literature, is highly related to sexual and relationship satisfaction, suggesting it may also be impacted by attachment style in romantic couples. However, the research conducted on sexual desire, sexual satisfaction, and attachment has been largely heterocentric, making it difficult to determine whether the findings documented in the literature thus far are relevant in a sexually diverse group of individuals...

Recent work shows that race is a critical factor in shaping sexual identities, partner preference, and family formation, suggesting there may be racial differences in whether lesbians already have children at the time that they look for companions. In this study, we draw on a sample of 1,923 lesbians on Match.com to quantitatively test whether there are racial differences in dating preferences for women with children, underscoring implications for family inequality through racial differences in who has children when looking for a partner...

Ariel B Handy, Cindy M Meston
Laboratory studies assessing physiological genital arousal have largely failed to find differences between women with and without female sexual arousal disorder (FSAD). Therefore, it is possible that women with FSAD may be unaware of their genital arousal response. The present study examined the extent to which women with FSAD can report their genital arousal response, as well as the role of interoception (body awareness) in this relationship. Additionally, this study examined the influence of interoception on the relationship between subjective and genital arousal...

The objective of this paper was to develop a measure of sexual script flexibility when approaching a sexual problem in a relationship. A series of online studies were conducted with individuals in relationships. As one subscale on the two-factor model had poor convergent and discriminant validity, a final single factor scale with 6-items was retained. The single factor scale demonstrated good model fit, high internal reliability, adequate convergent and discriminant validity, and moderate test re-test reliability...

Young women face a difficult situation when they live in a prostitution area or red light district. A phenomenological approach was applied to explore the experiences in maintaining reproductive health of 10 young women living in the prostitution area in Lampung, one of the provinces in Sumatra. Thematic content analysis found 7 themes including: (1) The participants' perception of prostitution as a place of naughty women and free sexual activity that can transmit STDs and influence adolescent psychology; (2) The ways the participants kept their reproductive organs healthy were through maintaining friendships, maintaining personal hygiene, avoiding free sexual activity, eating healthy food, and having routine medical checkups; (3) Information support was gained from family, health workers, media, and teachers; (4) Emotional support from family and friends; (5) Barriers to maintaining good health were inaccessible health facilities and an underfunded health service; (6) The needs of the participants were reproductive health services and clean environment; (7) The participants hoped for health education and intensive health services with friendly nurses...

A workshop at the recent International Conference on Mycorrhiza was focused on species recognition in Glomeromycotina and parts of their basic biology that define species. The workshop was motivated by the paradigm-shifting evidence derived from genomic data for sex and for the lack of heterokaryosis, and by published exchanges in Science that were based on different species concepts and have led to differing views of dispersal and endemism in these fungi. Although a lively discussion ensued, there was general agreement that species recognition in the group is in need of more attention, and that many basic assumptions about the biology of these important fungi including sexual or clonal reproduction, similarity or dissimilarity of nuclei within an individual, and species boundaries need to be re-examined and scrutinized with current techniques...

In contrast to the important role of hormones in the development of sexual traits in vertebrates (Cox, et al. 2009), the differentiation of these traits in insects is attributed almost exclusively to cell-autonomous mechanisms controlled by members of the sex determination pathway (Verhulst and van de Zande 2015), such as doublesex (dsx). Although hormones can shape the development of sexual traits in insects, variation in hormone levels are not conclusively known to cause dimorphism in these traits (Prakash and Monteiro 2016)...

Background: Little is known about the natural history of HPV infection in male virgins. This study estimated incidence and clearance of genital HPV, and factors associated with HPV, among men who deny ever engaging in penetrative sex at baseline. Methods: A cohort of 4123 men residing in Brazil, Mexico, and the USA were followed every 6 months for up to 10 visits. Genital exfoliated cells were collected and genotyped for 36 HPV types. Eighty-seven men were classified as virgins and included for analysis...

To characterize the epidemiology of HIV in Paraguay, from january to december, in 2015. The epidemic remains focused in those groups under risk, predominantly male. The characteristics of the study population shows that most of the affected were from the central area and from the capital city, and sexual transmission remains the most common pathway, with delayed diagnosis, which is reflected by the percentage of people presenting a low CD4 cell count.

BACKGROUND: A man-made chemical disaster occurred in the Amur River, leading to posttraumatic stress disorder (PTSD) in the Nanai people indigenous to the river's surrounding area. PTSD severity measured by the total scores of Impact of Event Scale-Revised (IES-R) (Total-I) and Clinician-Administered PTSD Scale (CAPS) (Total-C) were not always identical in terms of demographic and ethnocultural characters. It is possible that the results derived using the Total-I and Total-C may differ for persons with different backgrounds and/or individual characteristics...
