Medical Students’ First Male Urogenital Examination: Investigating the Effects of Instruction and Gender on Anxiety

Objectives: To investigate the effect that standardized instruction of the male urogenital examination had on the anxiety levels of students and to determine what influence, if any, the gender of the student had on this experience. Methods: One hundred thirty six second year medical students were asked to report their level of anxiety before and after participation in a small group teaching session on the male urogenital examination. We gathered both qualitative and quantitative information to better understand students’ anxiety surrounding this instruction. Results: Students had significantly lower state-anxiety scores following the instruction than before (F(1, 76)=102.353, p=.000, eta2=.574) and female students were more likely to have greater state-anxiety than male students (F=6.952, p=.010, eta2=.084). Ninety-nine percent of students reported that the teaching associates successfully reduced their anxiety. This decrease was attributed predominantly to the personal qualities of the teaching associates and to the format of the instruction. Conclusions: This study provides both quantitative and qualitative evidence that the use of male teaching associates to provide standardized instruction on the urogenital exam is effective at reducing students’ anxiety, particularly with regard to female students. Added standardized instruction may lead to increased confidence, skill, and future compliance with intimate physical exam screening practices

Memes And Advertising

This is a study on how the current trend of internet memes has come into play as a way of advertising. The study cover that of user-generated content as well as that of sponsored media in which the hopes is to go viral. For this study an internet survey was done in order to see how the public feels about memes as a form of advertising

Synthesis and Application of (R)-3-Methylpyrrolidine-3-Carboylic Acid

L-Proline is an amino acid widely used in pharmaceutical and biotechnological research due to its catalytic activity and biological relevance. L-Proline has been recognized and utilized as an organocatalyst, which allows cleaner, more sustainable reactions. However, one issue with L-proline is its low solubility in organic systems, limiting its reactivity and efficiency, especially when considering industrial research. Two reactions that utilize L-Proline are the Michael and Aldol but require 100 mol% of L-Proline and 30 mol% of L-Proline, respectively. This research will focus on the synthesis of an analogue of L-Proline utilizing inexpensive, commercially available reagents. A variety of organic reactions are used to generate the analogue whose structure is adapted for better solubility. The analogue is known to the Masterson research group and involves a multi-step synthesis, so efforts to improve the current synthetic strategy were made to maximize the efficiency of the production for the analogue. The current method has shown to be the most efficient pathway allowing maximum production at each step. Future goals for the project will include using organic reactions, including Aldol and Michael, to analyze the solubility and reactivity of the analogue and compare with studies performed with L-Proline

Performance of Booroola Merino and Finnsheep crossbred lambs and ewes

Booroola Merino (B, n= 18) and Finnsheep (F, n =31) rams were mated to F ewes and C3 ewes (1/2 Columbia, 1/4 Suffolk, 1/4 Hampshire). Progeny of these matings were evaluated for performance traits including ewe reproduction through 3 years of age. Averaged over dam breeds, there was no significant difference between B and F sires for conception rate (CR), litter size (LS) at birth or weaning or for lamb mortality to weaning. The difference among sire breeds was not large or significant for birth weight but F sired lambs were significantly heavier than B sired lambs at 63 and 147 days of age. Relative to F sired lambs, B sired lambs had a higher dressing percentage and less fat at the 12th rib but equal estimated percentage kidney fat. A significantly smaller percentage of B-C3 than F, F-C3 or B-F ewe lambs reached puberty by the end of their first breeding season. Ovulation rate at first mating was higher but embryo survival rate tended to be lower for B sired ewes than for F sired ewes. At 2 years of age, B sired ewes produced about 1 kg more wool than F sired ewes. With the exception of the very poor CR of B-C3 ewes at first parity, the differences between the four ewe genotypes were not large or significant for CR at first, second and third parity. The difference between B and F sired ewes in LS at birth was not significant at first parity but B sired ewes were more prolific at second and third parities. However, differences in lamb mortality reduced, and in some cases removed, the differences in LS by weaning time. Relative use of these breeds in commercial U.S. production schemes is discussed

Elastic Correlations in Nucleosomal DNA Structure

The structure of DNA in the nucleosome core particle is studied using an elastic model that incorporates anisotropy in the bending energetics and twist-bend coupling. Using the experimentally determined structure of nucleosomal DNA [T.J. Richmond and C.A. Davey, Nature {\bf 423}, 145 (2003)], it is shown that elastic correlations exist between twist, roll, tilt, and stretching of DNA, as well as the distance between phosphate groups. The twist-bend coupling term is shown to be able to capture these correlations to a large extent, and a fit to the experimental data yields a new estimate of G=25 nm for the value of the twist-bend coupling constant
