In this study, results of parametric effects and optimization turbidity removal from produced water using response surface methodology (RSM) artificial neural network (ANN) based on a statistically designed experimentation via the Box–Behnken design (BBD) are reported. A three-level, three-factor BBD was employed dosage (x1), time (x2) temperature (x3) as process variables. quadratic polynomial...

The cellular autophagy response induced by herpes simplex virus 1 (HSV-1) is countered by the viral γ34.5 protein. γ34.5 modulates autophagy by binding to the host autophagy protein Beclin-1 and through this binding inhibits the formation of autophagosomes in fibroblasts and neurons. In contrast, in this study dendritic cells (DCs) infected with HSV-1 showed an accumulation of autophagosomes an...

The effect of strenuous physical activity on the incidence of benign breast disease and benign tumours of the female reproductive system is unknown. Previous findings of a lower prevalence of breast cancer and cancers of the reproductive system among former college athletes compared to non-athletes (Frisch et al., 1985) suggested that former athletes and non-athletes might also differ in the pr...

IN the last several decades great progress has been made in describing how the separate systems of the brain function. Less progress has been made in obtaining a global picture of higher brain functions such as learning and memory. One of the obstacles in this research is that it is currently infeasible to completely enumerate the anatomy or to simultaneously record the activity of all neurons ...

PURPOSE The aim of this research was to develop and optimize a process for obtaining poly ɛ-caprolactone (PCL) nanoparticles loaded with Uncaria tomentosa (UT) extract. METHODS Nanoparticles were produced by the oil-in-water emulsion solvent evaporation method. Preliminary experiments determined the initial conditions of the organic phase (OP) and of the aqueous phase (AP) that would be utili...
