Chicken nugget is a comminuted meat product commonly prepared from spiced chicken meat and other ingredients. The tenderness of chicken meat lowers its firmness and mouth feel which may reduce acceptability of chicken nugget made from it. Thus, acceptability of chicken nugget could be harnessed when legume flour extenders are used along. Therefore, acceptability as well as quality of chicken nugget from different legume flours were evaluated. Soyabean, groundnut and cowpea flours were used as meat extenders for development of raw chicken nuggets and thereafter cooked for consumption. The quality of both raw and cooked legume flour extended chicken nuggets were assessed based on functional properties, sensory properties, proximate composition, amino acid content and shelf stability in terms of lipid peroxidation and microbial load. In their raw state, the legume flour extenders competed favourably with each other. Among all, soyabean flour extender maintained remarkable functional properties that transcend into significant (P < 0.05) yield of 86.93% of chicken nugget in comparison to the control (86.37%), groundnut (84.95%) and cowpea (84.50%). Upon cooking, all the legume flour extended chicken nuggets varied in their quality attributes. Apart from the high level of flavour and low microbial load, cowpea extended chicken nugget was of low quality based on the parameters evaluated in comparison with other legume flour extended chicken nuggets. Of interest, soyabean extended chicken nugget followed by groundnut extended chicken nugget were of good quality based on sensory properties, high crude protein and amino acid levels, low cholesterol content and lipid peroxidation value as well as low microbial load.

This study is devoted to investigate the effect of induced magnetic field on fully developed magnetohydrodynamic(MHD)natural convection flow of electrically conducting fluid in a vertical annular micro-channel formed by two concentric cylinders in the presence of imposed radial magnetic *** velocity slip and temperature jump at the annular micro-channel surfaces are taken into *** influence of induced magnetic field arising due to the motion of an electrically conducting fluid is taken into *** governing equations of the motion are a set of simultaneous ordinary differential equations and their exact solutions in dimensionless form have been obtained under relevant boundary *** expressions for velocity field,the induced magnetic field,temperature field,induced current density and skin friction have been obtained.A parametric study of the physical parameters is conducted and a representative set of numerical results for the velocity field,the induced magnetic field,temperature,induced current density,volume flow rate and skin friction are illustrated graphically to show interesting features of the radius ratio,rarefaction,fluid wall interaction,Hartmann number and the magnetic Prandtl *** the course of investigation,it is found that for fixed value of Hartmann number,the skin friction profiles in the presence of induced magnetic field are higher compared to the case when the induced magnetic field is neglected.

Exercise has well-characterized therapeutic benefits in the management of type 2 diabetes mellitus(T2DM).Most of the beneficial effects of exercise arise from the impact of nuclear factor erythroid 2 related factor-2(Nrf2)activation of glucose ***2 is an essential controller of cellular anti-oxidative capacity and circadian *** circadian rhythm of Nrf2 is influenced by circadian genes on its expression,where the timing of exercise effects the activation of Nrf2 and the rhythmicity of Nrf2 and signaling,such that the timing of exercise has differential physiological *** in the evening has beneficial effects on diabetes management,such as lowering of blood glucose and *** mechanisms responsible for these effects have not yet been associated with the influence of exercise on the circadian rhythm of Nrf2 activity.A better understanding of exercise-induced Nrf2 activation on Nrf2 rhythm and signaling can improve our appreciation of the distinct effects of morning and evening *** review hypothesizes that activation of Nrf2 by exercise in the morning,when Nrf2 level is already at high levels,leads to hyperactivation and decrease in Nrf2 signaling,while activation of Nrf2 in the evening,when Nrf2 levels are at nadir levels,improves Nrf2 signaling and lowers blood glucose levels and increases fatty acid *** the effects of Nrf2 activators on rhythmic signaling could also provide valuable insights into the optimal timing of their application,while also holding promise for timed treatment of type 2 diabetes.
