Abstract Background Increasing antibiotic resistance continues to focus on research into the discovery of novel antimicrobial agents. Due its and wound healing-promoting activity, metal nanoparticles have attracted attention for dermatological applications. This study is designed investigate scope bactericidal potential zinc ferrite (ZnFe 2 O 4 NPs), mechanism anti-bacterial action along with cytocompatibility, hemocompatibility, healing properties. Results ZnFe NPs were synthesized via a...

Abnormalities contributing to the pathogenesis of non-insulin-dependent diabetes mellitus include impaired beta cell function, peripheral insulin resistance, and increased hepatic glucose production. Glucocorticoids are diabetogenic hormones because they decrease uptake increase In addition, may directly inhibit release. To evaluate that possible role glucocorticoids in function independent their other effects, transgenic mice with an glucocorticoid sensitivity restricted cells were...

Abstract The published correlations for the velocity-voidage relationship observed during fluidization and sedimentation of uniformly sized spherical particles in solid-liquid systems are compared with experimental results. It is found that expression suggested by Richardson Zaki represents data well over a wide range values Galileo number (10−2 < Ga< 1010) voidage (0·4 ϵ 1). Methods given predicting constants as function properties system, including wall effects. KEYWORDS: Fluidized...

Minerals are one of the components food, though they not synthesized in body but essential for optimal health. Several metals required proper functioning many enzymes, transcriptional factors and proteins important various biochemical pathways. For example Zn, Mg Mn cofactors hundreds Zn is involved synthesis secretion insulin from pancreatic beta-cells. Similarly, Cr enhances receptor activity on target tissues, especially muscle cells. Insulin key hormone to maintain blood glucose level...

Abstract The cobalt oxide nanoparticles (Co 3 O 4 NPs) were synthesized via the green method using Piper nigrum ( P. ) leaves extract and calcined at different temperatures. crystalline nature was studied through x-ray diffractometer (XRD). With increasing calcination, amorphous phase transitioned to phase. Diffuse reflectance spectroscopy (DRS) used observe UV-Visible light absorbance phenomenon, Tauc’s plot calculate band gap energy, which found decrease with calcination. Scanning electron...

Summary A relationship has been reported between trace elements and diabetes mellitus. This study evaluated the role of such a in 83 patients with non-insulin dependent mellitus (40 men 43 women), mean duration 3.9 +/- 3.6 years. Patients nephropathy were excluded. Thirty healthy non-diabetic subjects studied for comparative analysis. Subjects subdivided into obese non-obese. Diabetic also controlled uncontrolled groups; control was based on fasting blood glucose serum fructosamine levels....
