Help-Seeking Barriers Among Sexual and Gender Minority Individuals Who Experience Intimate Partner Violence Victimization

Sexual and gender minority (SGM) individuals experience intimate partner violence (IPV) victimization at disproportionate rates compared to cisgender and heterosexual individuals. Given the widespread consequences of experiencing IPV victimization, intervention and prevention strategies should identify readily accessible and culturally competent services for this population. SGM individuals who experience IPV victimization face unique individual-, interpersonal-, and systemic-level barriers to accessing informal and formal support services needed to recover from IPV. This chapter reviews IPV victimization prevalence rates among SGM individuals in the context of minority stress and highlights unique forms of IPV victimization affecting this population, namely identity abuse. The literature on help-seeking processes among IPV survivors in general and help-seeking patterns and barriers specifically among SGM individuals who experience IPV victimization in the context of minority stress (e.g., discrimination, internalized stigma, rejection sensitivity, identity concealment) are discussed. How minority stressors at individual, interpersonal, and structural levels act as barriers to help-seeking among SGM individuals experiencing IPV victimization is presented. The chapter concludes with a review of emerging evidence for interventions aimed at reducing help-seeking barriers among SGM individuals who face IPV victimization and a discussion of future directions for research on help-seeking barriers in this population

Does Glycine max leaves or Garcinia Cambogia promote weight-loss or lower plasma cholesterol in overweight individuals: a randomized control trial

<p>Abstract</p> <p>Background</p> <p>Natural food supplements with high flavonoid content are often claimed to promote weight-loss and lower plasma cholesterol in animal studies, but human studies have been more equivocal. The aim of this study was firstly to determine the effectiveness of natural food supplements containing <it>Glycine max </it>leaves extract (EGML) or <it>Garcinia cambogia </it>extract (GCE) to promote weight-loss and lower plasma cholesterol. Secondly to examine whether these supplements have any beneficial effect on lipid, adipocytokine or antioxidant profiles.</p> <p>Methods</p> <p>Eighty-six overweight subjects (Male:Female = 46:40, age: 20~50 yr, BMI > 23 < 29) were randomly assigned to three groups and administered tablets containing EGML (2 g/day), GCE (2 g/day) or placebo (starch, 2 g/day) for 10 weeks. At baseline and after 10 weeks, body composition, plasma cholesterol and diet were assessed. Blood analysis was also conducted to examine plasma lipoproteins, triglycerides, adipocytokines and antioxidants.</p> <p>Results</p> <p>EGML and GCE supplementation failed to promote weight-loss or any clinically significant change in %body fat. The EGML group had lower total cholesterol after 10 weeks compared to the placebo group (p < 0.05). EGML and GCE had no effect on triglycerides, non-HDL-C, adipocytokines or antioxidants when compared to placebo supplementation. However, HDL-C was higher in the EGML group (p < 0.001) after 10 weeks compared to the placebo group.</p> <p>Conclusions</p> <p>Ten weeks of EGML or GCE supplementation did not promote weight-loss or lower total cholesterol in overweight individuals consuming their habitual diet. Although, EGML did increase plasma HDL-C levels which is associated with a lower risk of atherosclerosis.</p

Independent, Rapid and Targeted Loss of Highly Repetitive DNA in Natural and Synthetic Allopolyploids of Nicotiana tabacum

Allopolyploidy (interspecific hybridisation and polyploidy) has played a significant role in the evolutionary history of angiosperms and can result in genomic, epigenetic and transcriptomic perturbations. We examine the immediate effects of allopolyploidy on repetitive DNA by comparing the genomes of synthetic and natural Nicotiana tabacum with diploid progenitors N. tomentosiformis (paternal progenitor) and N. sylvestris (maternal progenitor). Using next generation sequencing, a recently developed graph-based repeat identification pipeline, Southern blot and fluorescence in situ hybridisation (FISH) we characterise two highly repetitive DNA sequences (NicCL3 and NicCL7/30). Analysis of two independent high-throughput DNA sequencing datasets indicates NicCL3 forms 1.6–1.9% of the genome in N. tomentosiformis, sequences that occur in multiple, discontinuous tandem arrays scattered over several chromosomes. Abundance estimates, based on sequencing depth, indicate NicCL3 is almost absent in N. sylvestris and has been dramatically reduced in copy number in the allopolyploid N. tabacum. Surprisingly elimination of NicCL3 is repeated in some synthetic lines of N. tabacum in their forth generation. The retroelement NicCL7/30, which occurs interspersed with NicCL3, is also under-represented but to a much lesser degree, revealing targeted elimination of the latter. Analysis of paired-end sequencing data indicates the tandem component of NicCL3 has been preferentially removed in natural N. tabacum, increasing the proportion of the dispersed component. This occurs across multiple blocks of discontinuous repeats and based on the distribution of nucleotide similarity among NicCL3 units, was concurrent with rounds of sequence homogenisation
