Looking back while moving forward: A justice-based, intersectional approach to research on contraception and disability.

Contraception 2019 Feb 11. Epub 2019 Feb 11.

Georgia State University.

For the first time in the twenty-first century, we have an emerging body of research regarding contraceptive use among adult women with disabilities in the United States. We highlight key findings from population-based analyses that found higher odds of female sterilization and lower odds of long-acting reversible contraception (LARC) use among women with disabilities compared to their peers without disabilities. We consider potential reasons underlying these differences, including discriminatory attitudes and policies that restrict the sexual and reproductive autonomy of people with disabilities. Read More

HIV diagnoses in migrant populations in Australia-A changing epidemiology.

PLoS One 2019 14;14(2):e0212268. Epub 2019 Feb 14.

Kirby Institute for Infection and Immunity, UNSW Sydney, Sydney, Australia.

Introduction: We conducted a detailed analysis of trends in new HIV diagnoses in Australia by country of birth, to understand any changes in epidemiology, relationship to migration patterns and implications for public health programs.

Methods: Poisson regression analyses were performed, comparing the age-standardised HIV diagnosis rates per 100,000 estimated resident population between 2006-2010 and 2011-2015 by region of birth, with stratification by exposure (male-to-male sex, heterosexual sex-males and females). Correlation between the number of permanent and long-term arrivals was also explored using linear regression models. Read More

Population size and self-reported characteristics and sexual preferences of men-who-have-sex-with-men (MSM) in Germany based on social network data.

PLoS One 2019 14;14(2):e0212175. Epub 2019 Feb 14.

Sigma Research, London School of Hygiene and Tropical Medicine, London, United Kingdom.

Background: In the absence of detailed information about the population size and behaviour data of men-who-have-sex-with-men (MSM), the estimation of prevalence rates of sexually transmitted infections (STIs) and the design of public health interventions become difficult. The aim of the present study is to estimate the lower boundary of age-specific population sizes and retrieve self-reported information from this population.

Methods: We used publicly accessible data from a large online dating and social network website for MSM in Germany to retrieve data on the age and regional distribution of profiles. Read More

Linking childhood emotional abuse and depressive symptoms: The role of emotion dysregulation and interpersonal problems.

PLoS One 2019 14;14(2):e0211882. Epub 2019 Feb 14.

Department of Psychology, Miami University, Oxford, Ohio, United States of America.

Childhood abuse is a major public health problem that has been linked to depression in adulthood. Although different types of childhood abuse often co-occur, few studies have examined their unique impact on negative mental health outcomes. Most studies have focused solely on the consequences of childhood physical or sexual abuse; however, it has been suggested that childhood emotional abuse is more strongly related to depression.

The Misclassification of Ambivalence in Pregnancy Intentions: A Mixed-Methods Analysis.

Perspect Sex Reprod Health 2019 Feb 14. Epub 2019 Feb 14.

Graduate Student Researcher, Sexual Health and Reproductive Equity (SHARE) Program, School of Social Welfare, University of California, Berkeley.

Context: Researchers have developed various measures of pregnancy ambivalence in an effort to capture the nuance overlooked by conventional, binary measures of pregnancy intention. However, the conceptualization and operationalization of the concept of ambivalence vary widely and may miss the complexity inherent in pregnancy intentions, particularly for young people, among whom unintended pregnancy rates are highest.

Methods: To investigate the utility and accuracy of current measures of pregnancy ambivalence, a mixed-methods study was conducted with 50 young women and their male partners in northern California in 2015-2016. Read More

Gender role conflict and sexual health and relationship practices amongst young men living in urban informal settlements in South Africa.

Cult Health Sex 2019 Feb 14:1-17. Epub 2019 Feb 14.

c Gender and Health Research Unit , South Africa Medical Research Council.

Qualitative research suggests that men's inability to achieve dominant forms of masculinity may be related to HIV-risk behaviours and intimate partner violence (IPV) perpetration. Using clustered cross-sectional data, we assessed how young men's gender role conflict was associated with HIV-risk behaviours in urban informal settlements in KwaZulu-Natal, South Africa. Gender Role Conflict and Stress (GRC/S) was measured using a South African adaptation of the GRC/S scale comprising three sub-scales: subordination to women; restrictive emotionality; and success, power and competition.

Scarcity mindset in reproductive health decision making: a qualitative study from rural Malawi.

Cult Health Sex 2019 Feb 14:1-16. Epub 2019 Feb 14.

b Division of Infectious Disease, College of Public Health , The Ohio State University , Columbus , OH , USA.

Poverty has widespread impacts on health. In dealing with resource scarcity, individuals' thoughts are narrowed to address immediate resource limitations, thus crowding out other information, a phenomenon called the scarcity mindset. To assess for indication of a scarcity mindset in sexual and reproductive decision making in rural Malawi, a setting with extreme resource scarcity, we collected qualitative data in the form of eight focus group discussions and 28 semi-structured, in-depth interviews with women and men of varying ages and marital status.

Advocating alternatives to mandatory reporting of college sexual assault: Reply to Newins (2018).

Am Psychol 2019 Feb-Mar;74(2):250-251

Department of Psychology, University of Oregon.

Our recent article "Compelled Disclosure of College Sexual Assault" examines college and university policies requiring most, if not all, employees to report student disclosures of sexual assault to university authorities, with or without student consent. We provided evidence that these mandatory reporting policies have become ubiquitous in American higher education, despite limited evidence of their safety or efficacy. Commenting on our article, Newins offers helpful advice for psychologists navigating the role of "responsible employee," such as seeking out information about their campus policy for reporting sexual assault disclosures and informing students of reporting mandates.

Ethical considerations of compelled disclosure of sexual assault among college students: Comment on Holland, Cortina, and Freyd (2018).

Authors:
Amie R Newins

Am Psychol 2019 Feb-Mar;74(2):248-249

University of Central Florida.

The recent article "Compelled Disclosure of College Sexual Assault" (Holland, Cortina, & Freyd, 2018) documents the variability in how campuses define responsible employees, reviews the assumptions underlying compelled disclosure, and offers alternatives to compelled disclosure. Compelled disclosure conflicts with several of the general principles of the American Psychological Association's (2016) ethics code and, as a result, is likely to conflict with the values of many psychologists. In this response, the ethical conflicts are identified and recommendations to psychologists to address these conflicts are offered. Read More

Biol Rev Camb Philos Soc 2019 Feb 14. Epub 2019 Feb 14.

Organismal and Evolutionary Biology, University of Helsinki, P.O. Box 65, FI-00014 Helsinki, Finland.

Human activities by altering environmental conditions are influencing the mate choice of animals. This is by impacts on: (i) the production and expression of traits evaluated by mate choosers; (ii) the transmission of information about potential mates to choosers; (iii) the reception and processing of the information by choosers; and (iv) the final mate choice. Here, I first discuss how these four stages of the mate-choice process can be altered by environmental change, and how these alterations, in turn, can influence individuals, populations, and communities.

Psychosocial Correlates of HIV Testing Frequency Among Men Who Have Sex with Men in Guangzhou, China.

AIDS Behav 2019 Feb 14. Epub 2019 Feb 14.

Graduate School of Public Health, University of Pittsburgh, Pittsburgh, PA, USA.

We examined sociodemographic and psychosocial factors associated with HIV testing patterns in the past 2 years among 492 HIV-negative men who have sex men (MSM) at an HIV testing center in Guangzhou, China. MSM who tested for HIV frequently were more likely to be older, reside in Guangzhou, and have higher monthly income. Compared with MSM who tested frequently, MSM who never tested were less likely to report that their sexual partner(s) had ever received HIV tests or that their good friends had ever received HIV tests, and were less likely to report having an HIV-positive gay friend or ever discussing HIV with sexual partners; they were more likely to report perceiving barriers to HIV testing.

Stockholm University, Sweden.

Seminal fluid proteins (SFPs), the non-sperm component of male ejaculates produced by male accessory glands, are viewed as central mediators of reproductive fitness. SFPs effect both male and female post-mating functions and show molecular signatures of rapid adaptive evolution. While Drosophila melanogaster is the dominant insect model for understanding SFP evolution, understanding of SFP evolutionary causes and consequences require additional comparative analyses of close and distantly-related taxa.

Dynamic inosinome profiles reveal novel patient stratification and gender-specific differences in glioblastoma.

Genome Biol 2019 Feb 13;20(1):33. Epub 2019 Feb 13.

RNA Editing Lab., Oncohaematology Department, IRCCS Ospedale Pediatrico "Bambino Gesù", Viale San Paolo, 15 00146, Rome, Italy.

Background: Adenosine-to-inosine (A-to-I) RNA editing is an essential post-transcriptional mechanism mediated by ADAR enzymes that have been recently associated with cancer.

Results: Here, we characterize the inosinome signature in normal brain and de novo glioblastoma (GBM) using new metrics that re-stratify GBM patients according to their editing profiles and indicate this post-transcriptional event as a possible molecular mechanism for sexual dimorphism in GBM. We find that over 85% of de novo GBMs carry a deletion involving the genomic locus of ADAR3, which is specifically expressed in the brain. Read More

Duplication of the chromosome number of diploid Brachiaria brizantha plants using colchicine.

Plant Cell Rep 2000 Jan;19(3):274-278

Centro Nacional de Pesquisa em Recursos Genéticos e Biotecnologia, CENARGEN/EMBRAPA, SAIN Parque Rural, Brasília, DF, Brazil, , , , , , BR.

 Some species of Brachiaria, generally tetraploid apomictic varieties, have become important forage grasses in the tropics. Breeding of Brachiaria depends on compatibility with the available apomitic tretraploid cultivars. This paper describes a procedure for chromosome duplication of two Bracharia brizantha diploid sexual accessions, using colchicine treatment of basal segments of in-vitro-grown plants. Read More

Evidence for somatic embryogenesis during plant regeneration from seedling-derived callus of dodder (Cuscuta trifolii Bab. et Gibs).

Plant Cell Rep 2000 Apr;19(5):525-528

Agricultural Biotechnology Center, H-2101 Gödöllő, P.O. Box 411, Hungary e-mail: Fax: +36-28-430416, , , , , , HU.

 In this paper comparative histological studies of embryo-like structures originating from callus cultures, and zygotic embryos originating from sexual seeds of Cuscuta trifolii are reported. The embryos of somatic cell and zygote origin showed similar morphological and anatomical features, such as a complete lack of cotyledon development and the differentiation of a developmentally unique root primordium specialised for water storage. Based on these findings, the regeneration of C. Read More

Characterization of Diversity Among Isolates of Rhizoctonia oryzae-sativae from California Rice Fields.

Plant Dis 2010 Jun;94(6):690-696

Department of Plant Pathology, University of California, Davis 95616.

Thirty-one California isolates of Rhizoctonia oryzae-sativae, the cause of aggregate sheath spot of rice, were characterized by culture morphology, pathogenicity tests, somatic compatibility groups (SCGs), single-locus microsatellites (SLMs), and multilocus microsatellites (MLMs). The highest level of diversity (individual isolates) was described by MLMs whereas pathogenicity tests exhibited the lowest resolution. In general, a high degree of diversity was revealed (diversity from 51. Read More

Systems for the removal of a selection marker and their combination with a positive marker.

Plant Cell Rep 2001 Jul 15;20(5):383-392. Epub 2014 Feb 15.

Pulp and Paper Research Laboratory, Nippon Paper Industries Co, 5-21-1, Oji, Kita-ku, Tokyo 114-0002, Japan, Japan.

Many systems have been developed for the removal of a selection marker in order to generate marker-free transgenic plants. These systems consist of (1) a site-specific recombination system (Cre/lox) or a phage-attachment region (attP) to remove the selectable marker gene and (2) a transposable element system (Ac) or a co-transformation system to segregate the gene of interest from the selectable marker gene. Overall, the process is more time-consuming than conventional transformation methods because two rounds of transformation - two steps of regeneration or sexual crossings - are required to obtain the desired transgenic plants.
