In vitro effect of aluminium (Al) on Fe(2+)-induced lipid peroxidation (LPX) in various subcellular fractions from the cerebral hemispheres (CH) of 7- and 30-day old chicks was studied. Stimulation of Fe(2+)-induced LPX by Al was observed to be the highest in microsomal fraction. The magnitude of elevation of Fe(2+)-induced LPX in various subcellular fractions of brain showed age related variat...

Soil sample from a site heavily contaminated with >10 wt.% zinc is sampled and extracted with aqueous solutions of ethylene diamine tetra-acetic cid (EDTA) that is a reagent frequently used to extract heavy metals in soil remediation. Three liquid/soil ratios (5/1, 20/1, and 100/1) were used n the extracting experiment. The molecular environment of the residual Zn in the EDTA-extract residues o...

The objective of the present study was to evaluate the influence of various root conditioning modalities on adsorption and adhesion of blood to scaled and planned root surfaces. This research work was done in the Department of Periodontics, DAV Dental College, Yamunanagar, Haryana, India (Year 2006-2009). The SEM analysis was done in ...SEM & TEM centre, Department of Radiology, AIIMS, New Delh...

Simultaneous determination of water-soluble B vitamins is a troublesome analytical procedure since they have greatly variable structures and acid-base properties which imposed difficulties on eluting them in short time selecting wavelength detection. The aim the present study was to develop simple method that overcomes these difficulties. successful simultaneous B1, B2, B3, B6, B9, B12 premix f...

Given the inherent qualities of this medium, particularly when contrasted to enamel bonding, bonding dentin is considered be a less dependable approach. Further, reduced, sizable amount cutting detritus coats dentin's exterior, forming smear layer. A steep decrease in interfacial adhesion over time has been attributed collagen web's inadequate resin impregnation as result dentinal surface prepa...

The in vitro antioxidant potential assay between ethanolic extracts of two species from the genus Vitex (Vitex negundo L. and Vitex trifolia L.) belonging to the Lamiaceae family were evaluated. The antioxidant properties of different extracts prepared from both plant species were evaluated by different methods. DPPH scavenging, nitric oxide scavenging, and β-carotene-linoleic acid and ferrous ...

Intravenous sodium calcium ethylene diamine tetra acetic acid (EDTA) and oral 2,3-dimercaptosuccinic acid (DMSA) have both been used to reduce the burden of lead in humans. Each of these agents enhances the mobilization of lead from different areas of the body - EDTA from the trabecular bone and DMSA from the soft tissue. A study of Korean battery workers revealed that EDTA appeared to increase...

Forming a bond to dentin has been a great challenge. Dentin is a vital tissue composed of organic material and water in addition to the inorganic content. Operative procedures on dentin produce a loosely-bound surface of unorganized material known as the "smear layer". For optimum bonding to occur, this layer needs to be removed or altered. A dentin bonding agent should be biocompatible and sho...
