ABSTRACT
Polycystic ovary syndrome is the most common endocrine disorder among women aged from 18 to 40 years. Its debilitating menstrual/obesity-related symptoms challenge conceptions of femininity. To date, age-related differences in women's body esteem and physicians' symptom management recommendations have not been investigated. Age moderated the relationships between symptom concerns and both sexual attractiveness and physical condition, but only for midlife, not for emerging adult women. Midlife women received holistic management information from physicians, while emerging adult women received weight management information. This study highlights the need for physician training to manage women's health and age-targeted body acceptance interventions for women diagnosed with polycystic ovary syndrome.

Synaptic vesicle endocytosis is critical for maintaining synaptic communication during intense stimulation. Here we describe Tweek, a conserved protein that is required for synaptic vesicle recycling. tweek mutants show reduced FM1-43 uptake, cannot maintain release during intense stimulation, and harbor larger than normal synaptic vesicles, implicating it in vesicle recycling at the synapse. Interestingly, the levels of a fluorescent PI(4,5)P(2) reporter are reduced at tweek mutant synapses, and the probe is aberrantly localized during stimulation. In addition, various endocytic adaptors known to bind PI(4,5)P(2) are mislocalized and the defects in FM1-43 dye uptake and adaptor localization are partially suppressed by removing one copy of the phosphoinositide phosphatase synaptojanin, suggesting a role for Tweek in maintaining proper phosphoinositide levels at synapses. Our data implicate Tweek in regulating synaptic vesicle recycling via an action mediated at least in part by the regulation of PI(4,5)P(2) levels or availability at the synapse.
