the objective of this study was to formulate and evaluate the drug-polymer interaction of mefenamic acid (ma) using two polymers with different characteristics as ethylcellulose (ec) and/or cellulose acetate phthalate (cap). microspheres were prepared by the modified emulsion solvent evaporation (mese). the effect of drug-polymer interaction was studied for each of microspheres. important param...

Transcription activation by Escherichia coli catabolite activator protein (CAP) at each of two classes of simple CAP-dependent promoters is understood in structural and mechanistic detail. At class I CAP-dependent promoters, CAP activates transcription from a DNA site located upstream of the DNA site for RNA polymerase holoenzyme (RNAP); at these promoters, transcription activation involves pro...

landfill gas is generated by organic waste decomposing under anaerobic conditions. landfill gas contributes to the emission in the atmosphere of greenhouse gases and causing global warming. humidity of environment is an effective parameter on rate of gas generation in landfills. saravan landfill is investigated as study area in this research. it located in 20 kilometers of rasht-tehran highway....

compound action potential (cap) of spinal cord represents valuable properties of neural fibers including excitability, rate of myelination and membrane integrity. these properties are measured using amplitude, latency and area under curve of caps recorded from spinal cord. here, the isolated spinal cord was set in a double sucrose gap (dsg) chamber and its response to intracellular stimulation ...

one of the main features of high throughput computing systems is the availability of high power processing resources. cloud computing systems can offer these features through concepts like pay-per-use and quality of service (qos) over the internet. many applications in cloud computing are represented by workflows. quality of service is one of the most important challenges in the context of sche...

today, information technology outsourcing (ito) has developed and caused organizations to become more flexible and dynamic than they were before. the ever-increasing development of ict is one of the main reasons for the promotion of outsourcing. that is due to the fact that many organizations are not able to adapt their hardware and software in accordance with the fast-paced technology developm...

BACKGROUND Community-acquired pneumonia (CAP) is more common in patients with COPD than in the adult general population, with studies of hospitalized CAP patients consistently reporting COPD as a frequent comorbidity. However, despite an increasing recognition of its importance, large studies evaluating the incidence patterns over time, risk factors and burden of CAP in COPD are currently lacki...

investigations in recent decades have shown an unexpected increase in aerosol concentrations in metropolitan and industrialized regions. it was sometimes followed by heat islands and probably decreases in precipitation due to an inadvertent cloud overseeding process. particle pollutants act like small cloud condensation nuclei in which they form large collections of small droplets in cloud. col...

Obsessive-compulsive disorder (OCD) is, as its name implies, characterized by obsessions (i.e., recurrent thoughts or images, particularly ones that cause distress) as well as compulsions (i.e., urges to perform mental or physical acts repeatedly), both of which significantly impair everyday functioning [1]. Obsessions are considered to be recurrent distressing impressions that something is wro...
