Binding femininity: an examination of the effects on tightlacing on the female pelvis

The corset in eighteenth and nineteenth century Europe was not merely an article of clothing. The corset was a complex and often contradictory social and cultural symbol. It symbolized both the sensual female body and the chaste virgin; the female control over male desires, and the male’s control over the female body. The ubiquity of the corset in the eighteenth and nineteenth century Europe is an important commentary on historical European society. Reports of women (and men) who have died as a result of the tightness of their corsets abound in the literature. Case studies from medical professionals provide information on the changes corsets wrought in the soft tissues of the women who wore them. However, to date, no systematic studies have been conducted which detail the changes in the bony pelvis. This study examines the effect of corseting upon the female and male pelvis of the Spitalfields skeletal collection, with consideration of consequential reduced fecundity and difficulties in parturition. Corseting status was determined through the presence or absence of compression on the ribs. Results show arcurate line length was significantly shorter in females with deformed ribs than in females with normal ribs, and the females with deformed ribs were significantly younger than the normal rib females. In addition, transverse diameter of the inlet and maximum femoral length approached significance, with females having deformed ribs being smaller. There was no significant relationship between pelvic contraction and deformed ribs, and deformed rib females retained a significantly larger pelvis than normal rib males. These data indicate that corseting did change the average size of the female pelvis, but not sufficiently to change the obstetrical sufficiency of the corseted pelvis

Using Remotely Accessible Microscopy in the Elementary Classroom

Elementary children are at an age of investigation and exploration. In today’s society, this exploration often occurs using technology. Whether learning to type with Typing Club, using Google to search for information on Yellowstone National Park or designing and creating a city in Minecraft, technology has become a part of every child’s existence. Early access to technology could be the impetus to a students’ pursuit of a degree in STEM disciplines. Presented here is a conglomerate of University, Community College and High School sites that provide free access to advanced scientific technologies remotely for students to view and manipulate for themselves. The Remotely Accessible Instruments in Nanotechnology (RAIN) Network provides Scanning Electron (SEM), Atomic Force (AFM) and Confocal Microscopes to educators and allows an opportunity to connect with higher education scientist across the globe, with the goal of using technology to enhance the teaching of science to our children

Food Restriction-Induced Changes in Gonadotropin-Inhibiting Hormone Cells are Associated with Changes in Sexual Motivation and Food Hoarding, but not Sexual Performance and Food Intake

We hypothesized that putative anorectic and orexigenic peptides control the motivation to engage in either ingestive or sex behaviors, and these peptides function to optimize reproductive success in environments where energy fluctuates. Here, the putative orexigenic peptide, gonadotropin-inhibiting hormone (GnIH, also known as RFamide-related peptide-3), and the putative anorectic hormones leptin, insulin, and estradiol were examined during the course of food restriction. Groups of female Syrian hamsters were restricted to 75% of their ad libitum food intake or fed ad libitum for 4, 8, or 12 days. Two other groups were food-restricted for 12 days and then re-fed ad libitum for 4 or 8 days. After testing for sex and ingestive behavior, blood was sampled and assayed for peripheral hormones. Brains were immunohistochemically double-labeled for GnIH and the protein product of the immediate early gene, c-fos, a marker of cellular activation. Food hoarding, the number of double-labeled cells, and the percent of GnIH-Ir cells labeled with Fos-Ir were significantly increased at 8 and 12 days after the start of food restriction. Vaginal scent marking and GnIH-Ir cell number significantly decreased after the same duration of restriction. Food hoarding, but not food intake, was significantly positively correlated with cellular activation in GnIH-Ir cells. Vaginal scent marking was significantly negatively correlated with cellular activation in GnIH-Ir cells. There were no significant effects of food restriction on plasma insulin, leptin, estradiol, or progesterone concentrations. In the dorsomedial hypothalamus (DMH) of energetically challenged females, strong projections from NPY-Ir cells were found in close apposition to GnIH-Ir cells. Together these results are consistent with the idea that metabolic signals influence sexual and ingestive motivation via NPY fibers that project to GnIH cells in the DMH
