introduction : this investigation evaluates the effects of mineral trioxide aggregate (mta), calcium hydroxide (ch) and calcium enriched mixture (cem) as pulp capping materials on dental pulp tissues. materials and methods: the experimental procedures were performed on eighteen intact dog canine teeth. the pulps were exposed. cavities were randomly filled with cem, mta, or ch followed by glass ...

Objective(s): To address the alarming problem of methicillin-resistant Staphylococcus aureus (MRSA), herein, a marine Streptomyces capable of producing an anti-MRSA compound has been studied.Materials and Methods: Strain MN41 was morphologically and physiologically characterized and then, molecularly identified using 16SrRNA analysis. To...

In the past few years, new technologies in the field of neuroscience have made it possible to simultaneously image activity in large populations of neurons at cellular resolution in behaving animals. In mid-2016, a huge repository of this so-called “calcium imaging” data was made publicly-available. The availability of this large-scale data resource opens the door to a host of scientific questi...

A recent effort to improve malic acid production by Saccharomyces cerevisiae by means of metabolic engineering resulted in a strain that produced up to 59 g liter(-1) of malate at a yield of 0.42 mol (mol glucose)(-1) in calcium carbonate-buffered shake flask cultures. With shake flasks, process parameters that are important for scaling up this process cannot be controlled independently. In thi...

PURPOSE To quantify the concentration of soft-tissue components of water, fat, and calcium through the decomposition of the x-ray spectral signatures in multi-energy CT images. METHODS Decomposition of dual-energy and multi-energy x-ray data into basis materials can be performed in the projection domain, image domain, or during image reconstruction. In this work, the authors present methodolo...

Acidification is an important process in the production of several dairy products and has impact taste, viscosity, shelf life products. This paper deals with development empirical mathematical model to describe milk acidification terms pH dynamics. The built upon experiments pasteurized skimmed for acid-induced casein precipitation extended predict partitioning calcium phosphates whey dynamics ...

This work is investigating the chemical grafting on Ti surface of a polymer/calcium phosphate coating of improved adhesion for enhanced bioactivity. For this purpose, a whole new methodology was developed based on covalently attaching a hyperbranched poly(ethylene imine) layer on Ti surface able to promote calcium phosphate formation in a next deposition stage. This was achieved through an inte...

Demand for microbial amylase production persists because of its immense importance in wide spectrum industries. The present work has been initiated with a goal of optimization of solid state fermentation condition for amylase using agroindustrial waste and microbial strain like B. amyloliquefaciens (MTCC 1270). In an aim to improve the productivity of amylase, fermentation has been carried out ...

Nanoformulation consisting of Streptomycin loaded chitosan-alginate nanoparticles were prepared using ionotropic-pregelation method and optimization was done in terms of polymer concentration, crosslinker concentration and stirring time. The optimal parameters were found to be Chitosan 0.75mg/ml, calcium chloride 1% (w/v) and stirring time 90 min. Polymer (chitosan and sodium-alginate) and cros...
