In the paper, by using radio frequency (RF) magnetron sputter technology, HfC coating grew on a 316L stainless steel substrate in an Ar atmosphere at various bias voltages from 0 to −200 V. From X-ray diffraction (XRD) and transmission electron microscopy (TEM) experiments, coatings were well crystallized (111) preferential growth had been successfully obtained controlling voltage Nanoindentati...

this study aimed to assess the anticariogenic and hemolytic activity of crude plant seed protein extracts against tooth decaying bacteria.the proteins from seeds of 12 different plants were extracted and used for antimicrobial assay against six different organisms. the extraction was carried out in 10mm of sodium phosphate buffer (ph 7.0). protein concentrations were determined as described by ...

abstract background and objective: snake venom is a complex of several toxic elements and enzymes. it has the agents with the ability to destroy cellular and subcellular membrane and to bring about hemolysis of red blood cells (rbc). two types of direct and indirect hemolytic activity are known in snake venom in that phospholipase a2 is responsible for the indirect lysis. the aim of this study ...

The hemolytic ability, the presence of cyl genes, and the diagnostic accuracy of cytolysin molecular detection were investigated in the genus Enterococcus by using 164 strains from 20 different species (26 reference strains, 42 clinical isolates from human and veterinary origin, and 96 isolates from ewe cheese and milk). Hemolysis was assayed with sheep and horse erythrocytes and under aerobic ...

The phenomenon of conglutination was first reported by Ehrlich and Sachs (1902), and subsequently received attention from Bordet and Gay (1906) and Bordet and Streng (1909). However, a systematic study of the mechanisms involved did not appear until Coombs and associates, in a commendable series of papers, reviewed the earlier work (Hole and Coombs, 1947a), applied the test to certain virus sys...

Problem statement: Although the diversity of marine Actinobacteria have been studied and biotechnologically exploited throughout the world, the studies on marine actinobacteria in Indian peninsula are largely unexplored. Of 9 maritime states in India, only 4 states have been extensively studied for the diversity of actinobacteria. Further, the studies on bioactive actinomycetes from saline soil...

background diabetes mellitus as a chronic metabolic disease occurs in patients with partial or complete deficiency of insulin secretion or disorder in action of insulin on tissue. the disease is known to provide conditions for overgrowth of candida species. candida spp. cause candidiasis by many virulence factors such as esterase, hemolysin and phospholipase. objectives this study aimed to comp...

The quantitative relationship between receptor binding and hormone secretion at the single-cell level was investigated in the present study by combining a reverse hemolytic plaque assay for measurement of luteinizing hormone (LH) secretion from individual pituitary cells with an autoradiographic assay of 125I-labeled gonadotropin-releasing hormone (GnRH) agonist binding to the same cells. In th...

BACKGROUND The aim of this study was to evaluate the dispersal effects of 3,5-dicaffeoylquinic acid (3,5-DCQA) against the preformed biofilm of Aspergillus fumigatus and to investigate its potential mechanism. MATERIAL AND METHODS Aspergillus fumigatus biofilms of laboratory strain AF293 and clinical strain GXMU04 were generated in 24- or 96-well polystyrene microtiter plates in vitro. Crystal ...

Biosurfactants, which are surface-dynamic specialists that can lessen both surface and interfacial pressure, have been seen as helpful for a long time. In the food business, they utilized adjustment, taste improvement, timeframe of realistic usability lengthening. The soaps, personal care consumer product sector utilize nearly 60% all surfactants. This envisaged in present study to collect 70 d...
