Antibacterial potency of methanol extracts of three green lower plants, Pneumatopteris afra, Platycerium bifurcatum and Nephrolepsis bisserata was determined using agar dilution method on clinical strains of Escherichia coli, Staphylococcus aureus, Klebsiella spp. and Salmomelia typhi. Antibacterial activities were observed at concentrations of 12.5, 25.0, 50.0 and 100.0 μg/ml. Their minimum inhibitory concentrations ranged from 12.5~100 μg/ml. Extracts of P. afra and P. bifurcatum were most active. Antibacterial activities observed with N. bisserata were less pronounced with no detectable activity at extract con-centrations of 12.5 and 25.0 μg/ml. E. coli, together with S. aureus appeared to be the most susceptible of the test bacteria while Klebsiella spp. was least sensitive. The significance of our findings is discussed. 相似文献

Using a cohort of 310 low‐income male adolescents living in an urban community and followed prospectively from 18 months through adolescence (ages 15–18 years), the current study examined whether individual, family, and community risk factors from ages 18 to 42 months were associated with adolescents' violent behavior, as indexed by juvenile petitions. Results of multivariate analyses indicated that although family income was the only factor to discriminate those with no arrest record from those with nonviolent arrests, rejecting parenting, child oppositional behavior, emotion regulation, and minority status during the toddler period contributed unique variance in distinguishing male adolescents arrested for violent behavior compared to those never arrested and those arrested for nonviolent behavior. Implications for prevention efforts are discussed. 相似文献

PurposeThe aim of the present study was to assess both the credibility and strength of evidence arising from systematic reviews with meta-analyses of observational studies on handgrip strength and health outcomes.MethodsAn umbrella review of systematic reviews with meta-analyses of observational studies was conducted. We assessed meta-analyses of observational studies based on random-effect summary effect sizes and their p values, 95% prediction intervals, heterogeneity, small-study effects, and excess significance. We graded the evidence from convincing (Class I) to weak (Class IV).ResultsFrom 504 articles returned in a search of the literature, 8 systematic reviews were included in our review, with a total of 11 outcomes. Overall, nine of the 11 of the outcomes reported nominally significant summary results (p < 0.05), with 4 associations surviving the application of the more stringent p value (p < 10−6). No outcome presented convincing evidence. Three associations showed Class II evidence (i.e., highly suggestive): (1) higher handgrip values at baseline were associated with a minor reduction in mortality risk in the general population (n = 34 studies; sample size = 1,855,817; relative risk = 0.72, 95% confidence interval (95%CI): 0.67–0.78), (2) cardiovascular death risk in mixed populations (n = 15 studies; relative risk = 0.84, 95%CI: 0.78–0.91), and (3) incidence of disability (n = 7 studies; relative risk = 0.76, 95%CI: 0.66–0.87).ConclusionThe present results show that handgrip strength is a useful indicator for general health status and specifically for early all-cause and cardiovascular mortality, as well as disability. To further inform intervention strategies, future research is now required to fully understand mechanisms linking handgrip strength scores to these health outcomes. 相似文献

This article reports on a survey study on the adoption and implementation of automation projects in federal university libraries in the south-west of Nigeria (SWN). The objectives are to ascertain the implementation status of automation projects, discuss the accruable benefits, investigate the library management system software being used, determine the modules already activated and fully implemented and their web presence, highlight the challenges encountered, draw conclusions and recommendations on enhancing successful implementation of library automation projects in Nigeria. The method used for gathering data for the study is questionnaire-based survey, using google form template. The findings of the study are that all the six federal university libraries in the SWN have adopted and implemented automation; two out of them are using open source integrated library automation software (Koha), one library uses in-house built integrated library system (ILS), while the remaining three use different proprietary software for their automation projects; and all the ILSs being used for automation projects are interoperable. The conclusion from the study is that the effective performance of libraries lies in the ability to access research materials and other relevant information contents with remarkable ease. This becomes achievable when libraries adopt and implement automation in their respective domains. 相似文献
