Sweat lactate reflects eccrine gland metabolism. However, the metabolic tendencies of eccrine glands in a hot versus thermoneutral environment are not well understood. Sixteen male volunteers completed a maximal cycling trial and two 60-min cycling trials [30°C?=?30±1°C and 18°C?=?18±1°C wet bulb globe temperature (WBGT)]. The participants were requested to maintain a cadence of 60 rev?·?min?1 with the intensity individualized at ～ 90% of the ventilatory threshold. Sweat samples at 10, 20, 30, 40, 50 and 60?min were analysed for lactate concentration. Sweat rate at 30°C (1380±325?ml?·?h?1) was significantly greater (P<0.05) than at 18°C (632±311?ml?·?h?1). Sweat lactate concentration was significantly greater (P<0.05) at each time point during the 18°C trial, with values between trials tending to converge across time. During the 30°C trial, both heart rate (20, 30, 40, 50 and 60?min) and rectal temperature (30, 40, 50 and 60?min) were significantly higher than in the 18°C trial. Higher sweat lactate concentrations coupled with lower sweat rates may indicate a greater relative contribution of oxygen-independent metabolism within eccrine glands during exercise at 18°C. Decreases in sweat lactate concentration across time suggest either greater dilution due to greater sweat volume or increased reliance on aerobic metabolism within eccrine glands. The convergence of lactate concentrations between trials may indicate that time-dependent modifications in sweat gland metabolism occur at different rates contingent partially on environmental conditions. 相似文献

This study examined the relationships between adult attachment, cognitive appraisal, and university students' behavioral and emotional reactions to infidelity situations in romantic relationships. Results based on 173 university students suggested that both attachment and cognitive appraisals significantly predicted distinct types of infidelity reactions and that participants' cognitive appraisal mediated the effects of attachment on behavioral and emotional reactions. Counseling applications for university counselors are discussed on the basis of attachment perspectives and cognitive appraisal models. 相似文献

The North Carolina Area Health Education Centers Library and Information Services (NC AHEC LIS) Network provides library outreach services to rural health care providers in all nine AHEC regions of North Carolina. Over the last twenty-five years, the AHEC and university-based librarians have collaborated to create a model program for support of community-based clinical education and information access for rural health care providers. Through several collaborative projects, they have supported Internet access for rural health clinics. The NC AHEC Digital Library—under development by NC AHEC, University of North Carolina at Chapel Hill, Duke University, East Carolina University, and Wake Forest University—will further extend access to electronic biomedical information and resources to health professionals in a statewide digital library. 相似文献

Lesbian, gay, and bisexual (LGB) college students from 12 university campuses (N = 177) participated in this study that examined the relationships between adult attachment, LGB identity, and sexual attitudes. Findings indicated that adult attachment was significantly related to LGB identity and sexual attitudes and that an LGB identity variable moderated the relationship between attachment avoidance and sexual permissiveness attitudes. Findings, counseling implications, and future research directions are discussed in terms of attachment and LGB identity theory. 相似文献

NC Health Info is an online collection of North Carolina based health services Web sites that seamlessly links local health resources to topical health information on MedlinePlus, the National Library of Medicine's consumer health information Web site. NC Health Info was the first project to connect local resources with MedlinePlus in the "Go Local" initiative. As such, NC Health Info serves as a model for other states to follow in connecting their own local information with Medline- Plus. This paper describes the processes used and lessons learned during a year-long evaluation of NC Health Info. Evaluation results may be of interest and applicable to any existing or planned "Go Local" project. 相似文献

This study examined the influences of generational status, self‐esteem, academic self‐efficacy, and perceived social support on 367 undergraduate college students' well‐being. Findings showed that 1st‐generation students reported significantly more somatic symptoms and lower levels of academic self‐efficacy than did non‐1st‐generation students. In addition, students' generational status was found to moderate predictive effects of perceived family support on stress. Implications for professional practices, limitations, and directions for future research are discussed. 相似文献
