[EX Q]: This study investigated the isolated and combined effects of heat [temperate (22\xa0°C/30\xa0% rH) vs. hot (35\xa0°C/40\xa0% rH)] and hypoxia [sea level (FiO2 0.21) vs. moderate altitude (FiO2 0.15)] on exercise capacity and neuromuscular fatigue characteristics.', 'Eleven physically active subjects cycled to exhaustion at constant workload (66\xa0% of the power output associated with their maximal oxygen uptake in temperate conditions) in four different environmental conditions [temperate/sea level (control), hot/sea level (hot), temperate/moderate altitude (hypoxia) and hot/moderate altitude (hot\xa0+\xa0hypoxia)]. Torque and electromyography (EMG) responses following electrical stimulation of the tibial nerve (plantar-flexion; soleus) were recorded before and 5\xa0min after exercise.', 'Time to exhaustion was reduced (P\xa0<\xa00.05) in hot (-35\xa0±\xa015\xa0%) or hypoxia (-36\xa0±\xa014\xa0%) compared to control (61\xa0±\xa028\xa0min), while hot\xa0+\xa0hypoxia (-51\xa0±\xa020\xa0%) further compromised exercise capacity (P\xa0<\xa00.05). However, the effect of temperature or altitude on end-exercise core temperature (P\xa0=\xa00.089 and P\xa0=\xa00.070, respectively) and rating of perceived exertion (P\xa0>\xa00.05) did not reach significance. Maximal voluntary contraction torque, voluntary activation (twitch interpolation) and peak twitch torque decreased from pre- to post-exercise (-9\xa0±\xa01, -4\xa0±\xa01 and -6\xa0±\xa01\xa0% all trials compounded, respectively; P\xa0<\xa00.05), with no effect of the temperature or altitude. M-wave amplitude and root mean square activity were reduced (P\xa0<\xa00.05) in hot compared to temperate conditions, while normalized maximal EMG activity did not change. Altitude had no effect on any measured parameters.

[EX Q]: Neisseria meningitidis are common colonizers of the human nasopharynx. In some circumstances, N. meningitidis becomes an opportunistic pathogen that invades tissues and causes meningitis. While a vaccine against a number of serogroups has been in effective use for many years, a vaccine against N. meningitidis group B has not yet been universally adopted. Bacterial heat shock protein complex (HSPC) vaccines comprise bacterial HSPs, purified with their chaperoned protein cargo. HSPC vaccines use the intrinsic adjuvant activity of their HSP, thought to act via Toll-like receptors (TLR), to induce an immune response against their cargo antigens. This study evaluated HSPC vaccines from N. meningitidis and the closely related commensal N. lactamica.', 'The protein composition of N. lactamica and N. meningitidis HSPCs were similar. Using human HEK293 cells we found that both HSPCs can induce an innate immune response via activation of TLR2. However, stimulation of TLR2 or TLR4 deficient murine splenocytes revealed that HSPCs can activate an innate immune response via multiple receptors. Vaccination of wildtype mice with the Neisseria HSPC induced a strong antibody response and a Th1-restricted T helper response. However, vaccination of mice deficient in the major TLR adaptor protein, MyD88, revealed that while the Th1 response to Neisseria HSPC requires MyD88, these vaccines unexpectedly induced an antigen-specific antibody response via a MyD88-independent mechanism.

[EX Q]: To investigate whether intracytoplasmic sperm injection (ICSI) can improve the clinical outcomes of the male patients with 100% teratozoospermia.', 'We retrospectively analyzed the clinical data of 152 couples undergoing in vitro fertilization-embryo transfer (IVF-ET), including 75 cycles of IVF and 77 cycles of ICSI. We compared the rates of normal fertilization, high-quality embryos, transferrable embryos, implantation, clinical pregnancy, and abortion between the two groups.', 'In the 100% teratozoospermia patients the number of transferrable embryos was significantly lower in the IVF than in the ICSI group (78.91% vs 84.92%, P < 0.05), while the rates of normal fertilization and implantation were higher in the former than in the latter (60.26% vs 57.87% and 48.00% vs 39.55%, both P > 0.05). There were no statistically significant differences between the two groups in the female age, Gn days, Gn dose, BMI, infertility duration, endometrial thickness, and basal serum FSH and E2.
