Background: Sexually transm.tted infections (STIs) such as chlam.dia and gonorrhea are com.only reported infections in the United States. Greater Om.ha has had continually higher reported rates of chlam.dia and gonorrhea for m.re than a decade com.ared to the rest of the state rates. m.nority and young adults have been disproportionately affected. Purpose: The objectives of our study were to estim.te the prevalence and to identify risk factors for chlam.dia and gonorrhea am.ng young adults. m.thods: We conducted a cross-sectional survey with 310 young adults aged 19 -25 years between June 2011 and June 2012. The study collected socio-dem.graphic, behavioral and other risk factors for STIs utilizing a pre-design standardized questionnaire. Gonorrhea and chlam.dia status of the participants were established by testing urine sam.les using PCR-based diagnostic technique. Descriptive and m.ltivariable regression analyses were used to exam.ne risk factors for STIs. Results: About 12.6% survey participants had at least one STI test positive. Lower education was associated with STIs but was not statistically significant (Odd Ratio for no schooling was 8.24, 95% CI 0.93 -72.86, Odd Ratio for high school education was 2.05, 95% CI 0.25 -16.63 com.ared to associate or college level education). No other predictors were associated with STIs. The average age of the first sexual intercourse was lower, and the num.er of sexual partners was higher com.ared to their national counterparts. Conclusion: We found a higher percentage of STI-positive individuals com.ared to previously reported county-level estim.tes. Education was the single and m.st im.ortant predictor of positive STI status.

Background: Anterior cruciate ligam.nt(ACL) injuries com.only occur during the early phase of landing and cutting tasks that involve sudden decelerations. The purpose of this study was to investigate the effects of jum. height and jum. speed on lower extrem.ty biom.chanics during a stop-jum. task and the effect of cutting speed on lower extrem.ty biom.chanics during a side-cutting ***: Thirty-six recreational athletes perform.d a stop-jum. task under 3 conditions: jum.ing fast, jum.ing for m.xim.m.height, and jum.ing for 60% of m.xim.m.height. Participants also perform.d a side-cutting task under 2 conditions: cutting at m.xim.m.speed and cutting at 60% of m.xim.m.speed. Three-dim.nsional kinem.tic and kinetic data were ***:The jum.ing fast condition resulted in increased peak posterior ground reaction force(PPGRF), knee extension m.m.nt at PPGRF,and knee joint stiffness and decreased knee flexion angle com.ared with the jum.ing for m.xim.m.height condition. The jum.ing for 60% of m.xim.m.height condition resulted in decreased knee flexion angle com.ared with the jum.ing for m.xrim.m.height condition. Participants dem.nstrated greater PPGRF, knee extension m.m.nt at PPGRF, knee valgus angle and varus m.m.nt at PPGRF, knee joint stiffness, and knee flexion angle during the cutting at m.xim.m.speed condition com.ared with the cutting at 60% m.xim.m.speed ***: Perform.ng jum. landing at an increased jum. speed resulted in lower extrem.ty m.vem.nt patterns that have been previously associated with an increase in ACL loading. Cutting speed also affected lower extrem.ty biom.chanics. Jum. speed and cutting speed need to be considered when designing AC.L injury risk screening and injury prevention program..

2000年6～11月对苏格兰拉姆岛上野化山羊（Caprahircus）种群的取食生态学进行了研究。研究表明：山羊的觅食回合长度变化范围从1m.n到460m.n不等，平均觅食回合长度是103．1±15．0（SD）m.n，雌性动物的觅食回合长度较雄性的长（P=0．077）。野化山羊单位时间的取食频率平均为46．3±0．6H／m.n，取食频率随性别（P=0．023）和月份（P〈0．001）而显著变化。雄性山羊在繁殖交配之前（6～7月）和之后（10～11月）的取食频率比繁殖交配期中（9～10月）的快（P〈0．008），但雌性动物并没有这样的变化（P=0．327）。雄性动物在繁殖交配期中的取食时间显著减少。雌、雄两性动物在取食频次和取食时间方面的这些差异可能导致该山羊种群在食物摄入量上的性别差异：雌性山羊的食物摄入量相对比较稳定，而雄性山羊的摄人量则变动很大。估计的食物摄人量随月份而下降（尽管9月份以后有一微小幅度的上升），这意味着拉姆岛上的山羊种群在食物匮乏而天气寒冷潮湿的冬季可能面临着能量收支不平衡的威胁。

The effect of acute and chronic cold exposure on heart rate (HR) and neuronal function in crayfish Procam.arus clarkii and prawns m.crobrachium.rosenbergii was addressed. This is particularly im.ortant since prawn farm. of this species are used for aquaculture in varied clim.tes world wide. The success of P. clarkii as an invasive species throughout the world m.y in part be due to their ability to acclim.te to cold and warm.habitats. A set of experim.nts was devised to address the physiological abilities of these species in m.naging rapid changes to cold environm.nts as well as their ability to respond to sensory stim.li by using behavior and a bioindex of HR. Prawns died within 2 hrs when m.ved from.21℃ to 5℃. Crayfish reduced their HR but survived for at least a week with this rapid change. Changes in tem.erature of 5℃ each week resulted in death of the prawns when 10℃ was reached. Som. died at 16℃ and som. lasted at 10℃ for 1 day before dying. Crayfish rem.ined responsive to sensory stim.li and survived with either rapid or slow changes in tem.erature from.21℃ to 5℃. Prim.ry sensory neurons were rapidly inhibited in prawns with an acute change to 5℃, where as in crayfish the activity was reduced but not com.letely inhibited. An induced sensory-CNS-m.tor circuit elicited activity at neurom.scular junctions in prawns and crayfish at 21℃ but with acute changes to 5℃only in crayfish was the circuit functionally intact. The ability to survive rapid environm.ntal tem.erature changes will im.act survival and in tim. the distribution of a species. The significance of these findings is that they m.y account, in part, for the wide ecological distribution of P. clarkii as com.ared to m. rosenbergii. The invasiveness of organism., as for P. clarkii, is likely linked to the physiological robustness to acute and chronic tem.erature changes of habitats.
