Investigations on the redox behaviour of manganese in manganese(II)–saccharin and manganese(II)–saccharin–1,10-phenanthroline complexes

AbstractThe redox behaviour of manganese system in Mn–Sac and Mn–Sac–Phen complexes were studied using cyclic voltammetry technique at glassy carbon electrode (GCE) in 0.1M KCl electrolyte. The CV of Mn–Sac solution is more or less similar to that of uncoordinated Mn (in MnCl2) accept slight difference in peak position and peak current. The presence of secondary ligand phenanthroline (in Mn–Sac–Phen complex) changes the CV of Mn system largely compared to those of uncoordinated Mn and Mn–Sac. The redox system is irreversible in Mn–Sac and quasi-reversible in Mn–Sac–Phen complex. The effect of concentration and pH on the redox behaviour of Mn system have been studied for both the complexes

Early childhood mortality and affecting factors in developing countries: an experience from Bangladesh

Within a method of a cross-sectional survey that adopts following as key variables i.e., demographic, socio-economic and health-care factors, thisstudy aimed to understand early childhood mortality rate and probable reasons in Bangladesh. In order to have probable rationality "logistic regression" of "multivariate statistical" technique is used to figure out the factors that are responsible for childhood mortality. The women who were married in the range of ageing 10-49 were asked to provide complete history about their "giving birth" for the reference period of 5 years. Statistical findings state that the rate of "national", "infant" and "under five year mortality" is, respectively 286, 461 and 525. Multi-examined statistical investigations sum up that "preceding birth interval", "birth order" and "number of living children" are significantly affect early childhood mortality. In addition, with the functionality of socio-economy, mother's education, source of drinking water and hygienic sanitation have also a significant impact on the rate of children mortality. Moreover, exposures to mass media, healtcare facilities have positive impact. Results also indicate that mothers who are more aware about helathcare are likely to be less mortality experience than their unaware counterparts

General and advanced diagnostic tools to detect Mycobacterium tuberculosis and their drug susceptibility: a review

Contains fulltext : 155340.pdf (publisher's version ) (Closed access)The global control of tuberculosis remains a great challenge from the standpoint of diagnosis, detection of drug resistance, and treatment, because treatment can only be initiated when infection is detected, and is guided by the results of antimicrobial susceptibility testing. To a large extent, non-molecular, immunological, and other biochemical methods are refinements or modifications of conventional methods, with the primary goal of providing more rapid test results. In contrast, molecular methods use novel technologies to detect the presence of Mycobacterium tuberculosis complex and genes conferring drug resistance. As a group, molecular technologies offer the greatest potential for laboratories in resource-rich countries because they have the highest sensitivity and specificity. In resource-poor settings, continued development of affordable, sensitive, and specific diagnostic tools will be required, where the incidence of disease is highest
