A non-invasive measure of minerals and electrolytes in tissue
A system for collecting epithelial cells from the oral mucosa for the determination of ion concentration is discussed with application to the study of man's adaptation to microgravity. A number of characteristics of these cells influenced the choice for clinical testing. They are non-cornified epithelial cells located on the inferior aspect of the tongue; therefore, they are well protected from trauma. They have the capability of reflecting relatively recent physiologic changes since they are renewed every three days and have aerobic metabolism. Most importantly, they are easily accessible and can be removed by a wooden applicator stick with minimum discomfort. Smears of cells removed in this manner show predominantly individual cells rather than sheets of contiuous cells. This facilitates the visual isolation of single cells with the electron microscope for analysis. NASA's principle effort in the development of a test to measure the ion concentration in sublingual cells has been research by the biomedical program carried out by scientists with expertise in skeletal metabolism. These efforts were directed toward determining the biological meaning and deviations in interacellular ions in nonhuman primates and in male volunteers for experiments in a model for weightlessness. A brief one page summary of the experiments and results are presented
Sexual expression among Black women in relationships with men from different minority racial groups
This research was a qualitative study designed to investigate the expression of Black woman in relationships with males from different racial minority groups. The primary objective was to learn more about how Black women express their sexuality in interracial relationships with their partners. This study interviewed a group of Black women (n=10) within interracial relationships and explored their experiences of expressing their sexuality within these relationships both psychologically and physically (Bean, 2002). Through their narratives, participants were able to convey the impact of their partner\u27s racial and/or cultural background on their sexual expression. The majority of these participants (n=7) would continue to date interracially, but they did bring up a number of issues that were challenging. One issue was the importance of communication within these relationships, where participants discussed the importance of having an open dialogue with their partner about their sexual, occupational, familial, and racial experiences. Looking specifically at sexuality in the context of race, the majority (n=8) of the participants had a positive view of sexual expression among Black women in relationships. Participants reported that generally Black sexual expression was characterized by strength , direction , and the pride of dressing their bodies. These findings are useful to clinical social workers who have clients in interracial relationships and may be struggling with issues of race and sexuality
Indirect effects of climate change on zinc cycling in sediments: The role of changing water levels
Increased variability in lake and river water levels associated with changing climate could impact the fate and effects of metals in redoxâsensitive sediments through the alteration of microbial communities and of acidâbase and redox chemistry. The objective of the present study was to determine the influence of water level fluctuation on metal speciation in porewater and predict environmental risk to highâcarbonate systems. Using experimental microcosms with sediments collected from 4 metalâcontaminated coastal freshwater wetlands in Michigan, USA, we conducted water level fluctuation experiments. Porewater and sediment metals (Ca, Cu, Fe, Mg, Mn, Ni, Zn) and important metal binding phases (ironâoxide speciation, acidâvolatile sulfide) were quantified. In a shortâterm drying (seiche) experiment, there were decreases in all porewater metals after inundation of saturated sediments. During a drought experiment, reâinundation of oxidized sediments increased porewater Cu, Zn, Mg, Ca for most sites. Porewater Zn increased after inundation to levels exceeding the US Environmental Protection Agency threshold for chronic toxicity. These data show that the dissolution of metal carbonates and metal sulfates contributes to metal release after reâflooding and indicate that we might expect increased ecological risk to organisms present in droughtâsensitive regions where altered hydroperiods are likely to increase metal bioavailability.

The Cauldron, 2015, Issue 02
Fall 2015, Issue 2 of The Cauldron. In The Cauldron\u27s first-ever online-only issue, we examine the everchanging idea of the gender binary through talking with those who believe in it and those who do not. We also preview TEDxCSU and showcase women\u27s soccer and the Rec Center\u27s new Pink Gloves Boxing class. We catch up with a CSU professor who wrote a local theatre piece and we examine why Issue 3 is a bad deal for pot smokers in Ohio.https://engagedscholarship.csuohio.edu/cauldron_archives/1001/thumbnail.jp
