TL;DR: In this article, the potential of chemically modified onion skin (CMOS) for cadmium (II) ions (Cd2+) from its aqueous solutions at different conditions of initial Cd2+ concentration, contact time, pH, and temperature was investigated under batch mode.
Abstract: The biosorption potential of chemically modified onion skin (CMOS) for cadmium (II) ions (Cd2+) from its aqueous solutions at different conditions of initial Cd2+ concentration, contact time, pH, and temperature was investigated under batch mode. The results showed that biosorption of Cd2+ is influenced by these different conditions. The equilibrium biosorption data were analyzed by two-parameter (Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich (D-R)), three-parameter (Redlich-Peterson, Sips, Toth, and Khan), and four-parameter (Baudu and Fritz-Schluender) isotherm models using linear and nonlinear regression methods. The best-fitting isotherms to describe the biosorption data of the Cd2+ CMOS system were found to be those of Freundlich, Sips, and Fritz-Schluender for the two-, three-, and four-parameter models, respectively. A maximum biosorption capacity (Qmax) of 18.34 mg/g was obtained for CMOS as compared with 11.90 mg/g for raw onion skin. The biosorption kinetics followed a pseudo second-ord...

TL;DR: Techniques such as immobilization, optimization strategies, proteinengineering and DNA recombinant technology have been used to improve keratinases activities and stabilities therebywidening the scope for commercialization.
Abstract: Keratinases are proteolytic enzymes capable of degrading rigid and insoluble keratinous proteins present in skinand appendages. They are produced in the keratinous substrates such as feather, hair, wool, nail, horn and hoof bymicroorganisms. They are mostly serine proteases, although there are very few reports about metallokeratinases.Keratinases are active over wide range of conditions, and are useful in biorecycling of keratin wastes into feed andfertilizers. They also have potential applications in leather, cosmetic, textile, biomedical and detergent industries. Thepromising applications of keratinases also extend to energy generation and green synthesis of nanoparticles. Owingto their ubiquitous biotechnological applications, techniques such as immobilization, optimization strategies, proteinengineering and DNA recombinant technology have been used to improve their activities and stabilities therebywidening the scope for commercialization. This review chronicles recent trends in the production and multi-functionalapplications of keratinases.

TL;DR: Anthropometric indices were significantly higher among the urban than the rural populations and Cardiovascular risks were equally more prevalent among theurban population.
Abstract: There is an increase of obesity and other cardiovascular risk factors worldwide, but especially in developing countries where multifaceted transitions are occurring. There is need for more evidence for the cardio-metabolic effect of changing lifestyles and urbanization in Nigeria. This study aimed at defining rural–urban differences in anthropometric parameters in two Nigerian communities of the same ancestral origin and to determine the cardiovascular risk correlates of these anthropometric measurements. This was a cross-sectional epidemiological study using stratified cluster sampling method. We studied 335 and 332 urban and rural dwellers respectively. A complete cardiovascular profile as well as anthropometric measurements was compared between the two populations. All anthropometric indices considered in this study (weight, BMI, waist circumference, waist circumference/height ratio, abdominal height; biceps, triceps, sub-scapular, abdominal, superior iliac skinfold thicknesses) were significantly higher in urban than in the rural population (p = <0.001). Overweight, obesity and hypertension were significantly prevalent among the urban population (p = <0.001) while there was no significant difference in the prevalence of dyslipidaemia (p = 0.096) and diabetes (p = 0.083) between the two cohorts. Females tend to have a higher chance of obesity than males although there was no gender difference in waist circumference and central skin fold thickness in the rural population. Age was the significant predictor of systolic blood pressure among the rural (R2 = 0.157, β = 0.258, p = 0.016) and urban female population (R2 = 0.201, β = 0.351, p = <0.001) while Abdominal height (R2 = 0.16, β = 0.281, p = 0.001) and waist circumference (R2 = 0.064 β = 0.064, p = .003) were predictors of systolic blood pressure in urban and rural men respectively. Anthropometric indices were significantly higher among the urban than the rural populations. Cardiovascular risks were equally more prevalent among the urban population. Appropriate health education and lifestyle modification strategies may reduce the increased burden of cardiovascular risk factors associated with rural–urban migration.
