Background:Muscular strength is an important component of physical fitness.We evaluated the relationship between baseline muscular strength and risk of stroke among adults who were aged≥65 years during follow-up.Methods:We included 7627 healthy adults(mean age=43.9 years,86.0%male)underwent a baseline physical examination between 1980 and 1989.Muscular strength was determined by 1-repetition maximum measures for bench press and leg press and categorized into age-and sex-specific tertiles for each measure.Cardiorespiratory fitness(CRF)was assessed via a maximal treadmill exercise test.Those enrolled in fee-for-service Medicare from 1999 to 2019 were included in the analyses.Associations between baseline strength and stroke outcomes were estimated using a modified Cox proportional hazards model.In a secondary analysis,we examined stroke risk by categories of CRF where Quintile 1=low,Quintiles 2-3=moderate,and Quintiles 4-5=high CRF based on age and sex.Results:After 70,072 person-years of Medicare follow-up,there were 1211 earliest indications of incident stroke.In multivariable analyses,the hazard ratio(95%confidence interval(95%CI))for stroke across bench press categories were 1.0(referent),0.96(0.83-1.11),and 0.89(0.77-1.04),respectively(p trend=0.14).The trend across categories of leg press was also non-significant(p trend=0.79).Adjusted hazard ratio(95%CI)for stroke across ordered CRF categories were 1.0(referent),0.90(0.71-1.13),and 0.72(0.57-0.92)(p trend<0.01).Conclusion:While meeting public health guidelines for muscular strengthening activities is likely to improve muscular strength as well as many health outcomes in older adults,performing such activities may not be helpful in preventing stroke.Conversely,meeting guidelines for aerobic activity is likely to improve CRF and lower stroke risk.

Background:We examined the associations of cardiorespiratory fitness(CRF) and white blood cell count(WBC) with mortality outcomes.Methods: A total of 52,056 apparently healthy adults completed a comprehensive health examination,including a maximal treadmill test and blood chemistry analyses.CRF was categorized as high,moderate,or low by age and sex;WBC was categorized as sex-specific quartiles.Results:During 17.8± 9.5 years(mean± SD) of follow-up,a total of 4088 deaths occurred.When regressed jointly,significantly decreased allcause mortality across CRF categories was observed within each quartile of WBC in men.Within WBC Quartile 1,all-cause mortality hazard ratios(HRs) with a 95% confidence interval(95%CI) were 1.0(referent),1.29(95%CI:1.06-1.57),and 2.03(95%CI:1.42-2.92) for high,moderate,and low CRF categories,respectively(p for trend <0.001).Similar trends were observed in the remaining 3 quartiles.With the exception of cardiovascular disease(CVD) mortality within Quartile 1(p for trend=0.743),there were also similar trends across CRF categories within WBC quartiles in men for both CVD and cancer mortality(p for trend <0.01 for all).For women,there were no significant trends across CRF categories for mortality outcomes within Quartiles 1-3.However,we observed significantly decreased all-cause mortality across CRF categories within WBC Quartile 4(HR=1.05(95%CI:0.76-1.44),HR=1.63(95%CI:1.20-2.21),and HR=1.87(95%CI:1.29-2.69) for high,moderate,and low CRF,respectively(p for trend=0.002)).Similar trends in women were observed for CVD and cancer mortality within WBC Quartile 4 only.Conclusion:There are strong joint associations between CRF,WBC,and all-cause,CVD,and cancer mortality in men;these associations are less consistent in women.

AIM: To study anxiolytic effect of a gastric pentade-capeptide, BPC-157. METHODS: In shock probe/burying test, pentadecapeptide BPC-157 (10 μg/kg, 10ng/kg, ip), diazepam (0.075, 0.0375 mg/kg, ip),and an equivolume of saline (5 mL/kg, ip) were givenat 30 min prior test. In light/dark test, the same dosageof diazepam, BPC-157, and saline were given at 45 minPrior procedure. RESULTS: Shock probe/buryingtest: rats treated with either diazepam or pentadecapeptideBPC-157 were much less afraid after the shock: almost

AIM: To investigate the effect of pentadecapeptide BPC 157 on chronic exposure to amphetamine in rats, particularly the changes commonly referred in chronic amphetamine studies as tolerance ( lesser grade of stereotyped behavior, without increased excitability) and reverse tolerance (ie, prominent stereotyped behavior and heightened startle response upon late amphetamine challenges). METHODS: After initial application (initial single dose-regimen), amphetamine (10 mg/kg, ip) was given once daily till d 5 ( continuous administration-regimen), and thereafter on d 8, 16, and 46 (intermittent administration regimen). For stereotyped behavior and heightened startle response the observation period was 120 min after amphetamine application, and each animal was observed for 10 s in 5 min intervals. Pentadecapeptide BPC 157 (10 μg/kg or 10 ng/kg, ip) or saline (5.0 mL/kg, ip) were given only at the beginning of the experiment, simultaneously with the initial dose of amphetamine. RESULTS: In relation to applied
