<p> This study examined the effect of sweat exposure on sexual attraction in heterosexual and homosexual women. Strictly heterosexual and homosexual female participants were exposed to underarm pads containing sweat. Samples were collected during the Stimulus Preparation Phase from healthy, strictly heterosexual men and women. Women&rsquo;s samples were collected on Day-14 and Day-27 of cycle, and men&rsquo;s from any two days. </p><p> In the Stimulus Exposure Phase, the male sweat and Day-14 female sweat samples were the experimental conditions, and the no male sweat and Day-27 female sweat were the controls. During the exposure phase, sweat samples were hidden and participants completed two computer tasks. First, the key-press task had participants view or skip male and female photographs. Second, the rating-task had participants rate attractiveness of the male and female photographs. The ratings and viewing times were collected then analyzed. </p><p> Heterosexual women showed a strong preference for male photos over female photos only when exposed to male sweat. They also preferred female photos less than homosexual women when exposed to male sweat or Day-14 female sweat. Homosexual women showed a strong preference for female photos over male photos when exposed to male or female Day-14 sweat. </p><p> Homosexual women also preferred female photos more than heterosexual women when exposed to male sweat or Day-14 female sweat. </p><p> The findings of this study suggest that exposure to male sweat may enhance heterosexual women&rsquo;s preference for men and exposure to female sweat from the ovulatory period of the menstrual cycle may inhibit the preference for women of heterosexual women. However, exposure to male sweat and female sweat from the ovulatory period may enhance the preference for women in homosexual women.</p>

<p> Given that mindfulness-based training techniques (MBT) stimulates and pushes one&rsquo;s core cognitive control capacity limits, brain stimulation techniques, such as transcranial direct current stimulation (tDCS), can be used to facilitate the ongoing neural patterns of functional connectivity toward long-lasting neuroplastic change. The current study assessed the combined effects of MBT with right frontal tDCS on cognitive control abilities and their corresponding brain patterns of activation using electroencephalography (EEG) and functional magnetic resonance imaging (fMRI). This study found an enhancement in working memory and sustained attention performance along with changes in the attention-related P3 component and its theta and alpha oscillatory profiles recorded by EEG. Furthermore, a reconfiguration in the chronnectome of large-scale resting-state networks was observed using resting-state fMRI, in addition to task-related changes in the polymodal neural architecture associated with encoding and adaptation, which may bridge the necessary connections from near to far transfer gains.</p>

Bioavailability of selenium (Se) in processed tuna and wheat products was studied in humans and rats. The protein source of the rat diets was torula yeast with Se supplied by either raw, precooked or canned tuna, or whole wheat flour, bread or bran. Sodium selenite was used as a control. Each Se source was fed at three levels; 0.05, 0.10 and 0.15 ppm. Using increase in glutathione peroxidase (GSH-Px) activity in various tissues of rats as an indicator of bioavailabiiity, no difference was seen among the three tuna products or among the three wheat products tested. However, significantly lower GSH-Px activity was found in the combined tuna groups as co»pared to the combined wheat groups, suggesting that the Se an wheat was more available than that in tuna. Se concentration m four rat tissues (Liver, Kidney, Whole blood and muscle) was also measured. A significant increase in the liver Se content of rats fed canned tuna over those fed raw or precooked tuna was observed. Since this did not correspond with an increase in GSH-Px activity it was concluded that it did not represent increased bioavaiiability of canned tuna. In the human experiment, eight young men ate controlled diets where the Se was supplied by either whole wheat bread or canned tuna for two week periods. The Se content of the tuna diet was 331.5 ug/day and the bread diet was 354 ug/ day. No difference was observed in whole blood GSH-Px or Se due to the tuna or bread diets but this may be due to the short time period. No significant difference in excretion of Se was observed in the balance study. On the tuna diet, the subjects excreted 72.7% of the Se consumed and on the bread diet they excreted 70.4%. / Graduation date: 1982
