Extraversion-Introversion and the Sexual Behavior of College Students

The purpose of this study was to determine if a relationship exists between extraversion-introversion and the sexual behavior of college students. Five predictions were proposed based on previous research which indicated the possibility of a relationship of the personality types of extraversion and introversion with some aspects of sexual behavior

EXTRAVERSION-INTROVERSION AND THE SEXUAL BEHAVIOR OP COLLEGE STUDENTS APPROVED: Major Professor <^5

The results obtained indicated that there is little correlation between Extraversion-Introversion and most of the areas investigated for the population sampled. A correlation coefficient was performed on the five predictions using the male sample only, the female sample only, and the entire sample with males and females combined. Two of the fifteen coefficients proved to be significant and were discussed along with other findings of the study. Weaknesses of the study were also cited and suggestions were given regarding the improvement of similar studies which may be done in the future. EXTRAVERSION-INTROVERSION AND THE SEXUA

Dietary soy and meat proteins induce distinct physiological and gene expression changes in rats

This study reports on a comprehensive comparison of the effects of soy and meat proteins given at the recommended level on physiological markers of metabolic syndrome and the hepatic transcriptome. Male rats were fed semi-synthetic diets for 1 wk that differed only regarding protein source, with casein serving as reference. Body weight gain and adipose tissue mass were significantly reduced by soy but not meat proteins. The insulin resistance index was improved by soy, and to a lesser extent by meat proteins. Liver triacylglycerol contents were reduced by both protein sources, which coincided with increased plasma triacylglycerol concentrations. Both soy and meat proteins changed plasma amino acid patterns. The expression of 1571 and 1369 genes were altered by soy and meat proteins respectively. Functional classification revealed that lipid, energy and amino acid metabolic pathways, as well as insulin signaling pathways were regulated differently by soy and meat proteins. Several transcriptional regulators, including NFE2L2, ATF4, Srebf1 and Rictor were identified as potential key upstream regulators. These results suggest that soy and meat proteins induce distinct physiological and gene expression responses in rats and provide novel evidence and suggestions for the health effects of different protein sources in human diets

Comparing clinical performance of current implantable cardioverter-defibrillator implantation recommendations in arrhythmogenic right ventricular cardiomyopathy

AIMS: Arrhythmogenic right ventricular cardiomyopathy (ARVC) patients have an increased risk of ventricular arrhythmias (VA). Four implantable cardioverter-defibrillator (ICD) recommendation algorithms are available The International Task Force Consensus (‘ITFC’), an ITFC modification by Orgeron et al. (‘mITFC’), the AHA/HRS/ACC guideline for VA management (‘AHA’), and the HRS expert consensus statement (‘HRS’). This study aims to validate and compare the performance of these algorithms in ARVC. METHODS AND RESULTS: We classified 617 definite ARVC patients (38.5 ± 15.1 years, 52.4% male, 39.2% prior sustained VA) according to four algorithms. Clinical performance was evaluated by sensitivity, specificity, ROC-analysis, and decision curve analysis for any sustained VA and for fast VA (>250 b.p.m.). During 6.4 [2.8–11.5] years follow-up, 282 (45.7%) patients experienced any sustained VA, and 63 (10.2%) fast VA. For any sustained VA, ITFC and mITFC provide higher sensitivity than AHA and HRS (94.0–97.8% vs. 76.7–83.5%), but lower specificity (15.9–32.0% vs. 42.7%-60.1%). Similarly, for fast VA, ITFC and mITFC provide higher sensitivity than AHA and HRS (95.2–97.1% vs. 76.7–78.4%) but lower specificity (42.7–43.1 vs. 76.7–78.4%). Decision curve analysis showed ITFC and mITFC to be superior for a 5-year sustained VA risk ICD indication threshold between 5–25% or 2–9% for fast VA. CONCLUSION: The ITFC and mITFC provide the highest protection rates, whereas AHA and HRS decrease unnecessary ICD placements. ITFC or mITFC should be used if we consider the 5-year threshold for ICD indication to lie within 5–25% for sustained VA or 2–9% for fast VA. These data will inform decision-making for ICD placement in ARVC

Planting Rate Effects on Sugarcane Yield Trials

ABSTRACT Temperate sugarcane (Saccharum spp. hybrids) growing regions, such as Louisiana, often use higher planting rates than tropical and subtropical sugarcane growing regions. The common production practice in Louisiana is to use three to four whole-stalks (lines) placed along side each other when planting sugarcane. The LSU AgCenter's sugarcane breeding program uses a two whole-stalk planting rate in all stages of the program. The objective of this study was to assess the effect of planting rate on sugar yield and its components in sugarcane yield trials. A second objective was to determine characteristics affecting bud germination of different sugarcane genotypes. Two experiments were conducted during 2000 through 2004 at two locations at the Sugar Research Station in St. Gabriel, Louisiana. Eight sugarcane genotypes were planted at planting rates of two, three, and four whole stalks. Data were collected in the plant-cane through third ratoon crops. The lack of a sugarcane planting rate by genotype interaction indicated that sugarcane genotypes performed similarly in yield trials whether a twostalk, three-stalk, or four-stalk planting rate was used. Only differences in magnitude were observed for the planting rates, which is of only minor consequence in breeding programs. Another experiment was conducted in 2002 with the same set of genotypes and germination traits were assessed. Correlation coefficients indicated no negative relationship s for percent germination. The current use of a two-stalk planting rate in sugarcane selection and yield trials within the breeding program appears valid
