High sensitive C-reactive protein (hs-CRP) level and lipid profiles of healthy volunteers with prehypertension

Coronary atherosclerosis still represents one of the main causes of death. Efficacious prevention should focus on early control of cardiovascular risk factors, including lipid profiles, which unable detect on sub-clinical cases. High-sensitive C-reactive protein (hs-CRP) can prove to be an early cardiac risk predictor. Aims of this study were to compare hs-CRP levels between healthy volunteer with normal blood pressure...

Production of laccase from a white rot fungi isolated from the Amazon forest for oxidation of Remazol Brilliant Blue-R

The purpose of this study was to investigate the production of laccase from a white rot fungi isolated from the Amazon forest for oxidation of Remazol Brilliant Blue-R (RBB-R). Initially, a small screening was carried out aiming to find laccase producers. The next step was to investigate, using factorial design and Response Surface Methodology (RSM), the influence of the content of glucose, peptone and CuSO4 in the...

Investigations on optimum possibility of replacing cement partially by redmud in concrete

Red mud is an industrial waste material generated during production of alumina from bauxite by Bayer process. These industrial wastes hold some heavy metals which are hazardous in nature. The aim of the paper is to investigate the possibility of partially replacing Portland cement in concrete by red mud and evaluating its compressive and splitting tensile strength. This study examines the effect of red mud on the...

Proposition of a low cost field assay to determine antiproliferative properties of indigenous plants using Dugesia dorotocephala (brown planaria)

Cancer is a major health problem, not only in developed countries, but also in developing countries where the number of cancer-related ailments is growing. Chemotherapy is the most commonly used treatment option but side effects associated with its use necessitates the search for alternatives. Over 80% of the population in developing countries relies on ethnomedicinal plants for primary healthcare including cancer....

Investigation of resonance characteristics and effective parameters of a metamaterial structure with split rings

This paper presents a new metamaterial, based on SRR structure and systematically investigate the various properties of the metamaterial structure. The resonant frequency of the proposed metamaterial structure is first estimated using its equivalent circuit model and the estimated value thus obtained is then compared with the values obtained by High Frequency Structure Simulator (HFSS) simulations. The negative...
