Sexuality and gender: change through reflection and action

Gender and sexuality inequalities lie at the root of poor sexual and reproductive health (SRH). An India-based non-governmental organization (NGO) implemented a field-based methodology to integrate gender and sexuality into existing SRH projects in two states. Personal and organizational change occurred through critical analysis and experiential exercises which normalized topics on sexuality for program staff and communities. Staff learned how biases prevented them from engaging with communities. Community women came to understand sexual pleasure as an important aspect of strengthening the family and community. Mapping women's mobility revealed the link between sexuality, mobility and family honour. Gender myths, portraying men as oppressors, made explicit the narrow and biased picture of men that perpetuates through social norms maintained by staff and not only by communities in which they work. Methods improved social relations and prompted both behaviour and social changes at the community level.     

How Picky Eating Becomes an Illness—Marketing Nutrient-Enriched Formula Milk in a Chinese Society

The essential adaptive food selection behavior of young children has become increasingly medicalized as a kind of disease—the “picky-eating” syndrome in Hong Kong. The researcher used the multiple case studies approach with data collected from in-depth interviews and advertisements to examine the process of the medicalization of picky-eating disorder, which demonstrates how an essential adaptive human behavior can be redefined by the market and medical system as a deviant, abnormal behavior that needs to be eliminated and how the resulting health risks can be resolved by modern medicine produced by this pharmaceutical nexus.     

TGF-B3 Dependent Modification of Radiosensitivity in Reporter Cells Exposed to Serum From Whole-Body Low Dose-Rate Irradiated Mice

Prior findings in vitro of a TGF-β3 dependent mechanism induced by low dose-rate irradiation and resulting in increased radioresistance and removal of low dose hyper-radiosensitivity (HRS) was tested in an in vivo model. DBA/2 mice were given whole-body irradiation for 1 h at low dose-rates (LDR) of 0.3 or 0.03 Gy/h. Serum was harvested and added to RPMI (4% mouse serum and 6% bovine serum).This medium was transferred to reporter cells (T-47D breast cancer cells or T98G glioblastoma cells). The response to subsequent challenge irradiation of the reporter cells was measured by the colony assay. While serum from unirradiated control mice had no effect on the radiosensitivity in the reporter cells, serum from mice given 0.3 Gy/h or 0.03 Gy/h for 1 h removed HRS and also increased survival in response to doses up to 5 Gy. The effect lasted for at least 15 months after irradiation. TGF-β3 neutralizer added to the medium containing mouse serum inhibited the effect. Serum from mice given irradiation of 0.3 Gy/h for 1 h and subsequently treated with iNOS inhibitor 1400W did not affect radiosensitivity in reporter cells; neither did serum from the unirradiated progeny of mice given 1h LDR whole-body irradiation.
