The main purpose of this study is to compare the perceived stress level of university students in terms of body-mass index categories and gender. 235 university students (183 female, 53 male) between the ages of 18-40 participated in the study. Participants were selected from six different departments of six universities by convenient sampling. In the study, a personal information form asking about university, department, age, disease status, drug use, weight, height and gender, and a perceived stress scale were used as data collection tools. While body mass index (BMI) categories and gender were determined as independent variables in the study, perceived stress level was determined as dependent variable and the data were analysed with a one-way ANOVA test. The findings revealed that there was no statistically significant difference in the perceived stress levels of the participants in terms of gender and body mass index categories. However, for one factor of the stress scale (readiness to cope with stress), participants in the normal body mass index range reported significantly less stress than participants in the obese body mass index range. The findings will be discussed in the light of the literature.

This study was conducted to determine the effect of production system, slaughter age, and gender on the nutrient composition, fatty acids profile, and index values of breast and thigh meat in Alectoris chukar partridges. Partridges were slaughtered at 14, 16, and 18 weeks of age and skinless breast and thigh meat of male and female were used in the study (a total of 96 samples in 2 replicates). The production system affected only the crude fat level of the thigh meat in terms of nutrient composition and it was found higher in the intensive system compared to the free-range system. Age and gender did not significantly affect the composition of breast and thigh meat. In terms of fatty acid profile, erucic acid (C22:1n9) level in breast meat was higher in intensive system, while it was higher in thigh meat in free-range. While the percentage of docosahexaenoic acid (C22:6n3) increased with age in breast meat, it decreased in thigh meat with age. While eicosenoic acid (C20:1) percentage was higher in breast meat of male birds compared to females, only stearic acid (C18:0) was found to be higher in thigh meat. Saturated fatty acids (SFA), linolenic acid (n3), thrombogenic index (TI) and atherogenic index (AI) values were higher in thigh meat produced in free-range system, while polyunsaturated fatty acids (PUFA), total unsaturated fatty acids (UFA), linoleic acid (n6) and hypocholesterolaemic / hypercholesterolaemic ratio (h/H) were significantly higher in intensive system. While SFA and TI levels in thigh meat decreased with age, monounsaturated fatty acids (MUFA), UFA and oleic acid (n9) percentages increased. MUFA / SFA in thigh meat of females was higher than males, other indexes were found insignificant. The results shows that partridges had desirable fatty acid composition. Especially, the increase in MUFA and UFA values with age in thigh meat compared to breast indicates that thigh meat is enriched in terms of unsaturated fatty acids. However, the higher SFA and AI values obtained in the free-range system could be considered a negative outcome for alternative production systems that prioritize bird welfare and consumer demands.

This study was carried out to detect the content of amino acid in female and male specimens of blue swimming crab (Portunus segnis) obtained from (including 12 male crab and also 12 female crab) North Eastern Mediterranean Sea, Turkey. The protein was identified as 17.63% and 18.13% for female and male crab respevtively. Totally 9 essential amino acids were recorded in the present study. Lysine and leucine constituted the highest essential amino acid (EAA) concentrations in P. segnis. This species was found to be in good score in terms of the level of EAA and the EAA/Non-EAA ratios when compared with other economical crab species.
