This paper draws on ethnographic, qualitative and survey data with transwomen in Puerto Rico to examine the social and political-economic context of lay injection with hormone and silicone - common practices within this community. We describe specific practices of hormone and silicone injection, the actors that govern them, the market for the sale and distribution of syringes and the networks of lay specialists who provide services to a population that is neglected by and largely excluded from biomedical settings. Our data derive from ethnographic observations, sociodemographic questionnaires, surveys and semi-structured interviews conducted with a diverse group of transwomen in metropolitan San Juan, Puerto Rico. Our analysis focuses on four overlapping social domains or processes that shape the practices of lay silicone and hormone injection among transwomen: (1) the circulation of gender transitioning technologies within local and global markets; (2) the tension between the social exclusion of transwomen and their resilient sub-cultural responses; (3) the cultural meanings that shape transwomen's attitudes about injection; and (4) the perceived consequences of injection. We conclude with a discussion of the kinds of intervention and policy changes that would respond to the factors that most endanger transwomen's health.

For individuals at high risk of developing breast cancer, interventions to mitigate this risk include surgical removal of their breasts and ovaries or five years treatment with the anti-estrogen tamoxifen or aromatase inhibitors. We hypothesized that a silicone based anti-estrogen-eluting implant placed within the breast would provide the risk reduction benefit of hormonal therapy, but without the adverse effects that limit compliance. To this end, we demonstrate that when placed adjacent to mammary tissue in the 7,12-dimethylbenz[a]anthracene-induced rat breast cancer model a fulvestrant-eluting implant delays breast cancer with minimal systemic exposure.

Purpose: To report a rare case of a Coats-like response developing after vitreoretinal surgery for proliferative diabetic retinopathy (PDR) and its successful management with retinal laser photocoagulation and adjunctive intravitreal steroids.
Case Description: A 52-year-old woman with a five-year history of type 2 diabetes mellitus and hypertension presented with decreased vision in the left eye (counting fingers at 1 m). Examination revealed high-risk PDR in both eyes, with a subtotal macula-off combined retinal detachment in the left eye.
The kinetically-derived maximal dose (KMD) is defined as the maximum external dose at which kinetics are unchanged relative to lower doses, e.g., doses at which kinetic processes are not saturated.

Ghrelin is an orexigenic peptide released by gastric ghrelin cells that contributes to obesity and hepatic steatosis. The mechanosensitive ion channel Piezo1 in gastric ghrelin cells inhibits the synthesis and secretion of ghrelin in response to gastric mechanical stretch. We sought to modulate hepatic lipid metabolism by manipulating Piezo1 in gastric ghrelin cells.
