chronic urticaria (cu) also known as chronic idiopathic urticaria results in a lowered quality of life (qol). disease specific questionnaires are necessary to assess qol in cu patients. chronic urticaria quality of life questionnaire (cu-q2ol) is the only available and validated disease specific questionnaire in the assessment of qol in cu patients originally developed in italian language. the ...
background: in its constitution of 1948, who defined health as “a state of complete physical, mental, and social well-being, and not merely the absence of disease and infirmity” . in 1994, the agency for health care policy and research published clinical practice guidelines recommending providers to routinely evaluate patients’ hrqol (health related quality of life) and use their assessment to ...
The measurement of microbial kill requires the ability to measure the number of surviving microorganisms with time after exposure to the antimicrobial agent. Bioburden determinations have the same requirement as they depend on the ability to recover viable microorganisms in the presence of potentially antimicrobial products or raw materials. However, carryover of residual disinfectant from the ...
A universal diluting fluid (UDF) was developed for use in membrane filtration sterility testing. Diuting fluid is used to free the filter membrane of preservative residues which could inhibit microbial recovery. Current procedures employ one of several fluids described by the United States Pharmacopeia. UF was designed to utilize the neutralizing capabilities of a combination of inactivating ag...
a simple, reproducible and rapid gas chromatographic method for precise determination of valproic acid (vpa) in human plasma has been developed. total time for sample preparation and gc analysis is less than 45 min. after plasma protein precipitation, vpa was extracted into chloroform with suitable recovery. by using stabilwax®-da capillary gc column, a symmetrical gas chromatographic peak was ...
Sequencing of DNA fragments (e.g., ITS, 16S, 18S, particular genes, and molecular markers) is increasingly required in studies on microbial diversity, microbial genetic population and phylogeny, sequencing of alleles, and searching for SNPs, among others. The cost of obtaining these DNAs, in quantity and quality for sequencing, is high as it involves special kits to recover DNA from gel after P...
Microbial communities are at the heart of all ecosystems, and yet microbial community behavior in disturbed environments remains difficult to measure and predict. Understanding the drivers of microbial community stability, including resistance (insensitivity to disturbance) and resilience (the rate of recovery after disturbance) is important for predicting community response to disturbance. Her...
A miniaturized, disposable microbial culture chip has been fabricated by microengineering a highly porous ceramic sheet with up to one million growth compartments. This versatile culture format, with discrete compartments as small as 7 x 7 mum, allowed the growth of segregated microbial samples at an unprecedented density. The chip has been used for four complementary applications in microbiolo...
cross infections (cis) are considered as a major public health problem worldwide. they cause delay in recovery, increased mortality and morbidity. the purpose of this study is to report the incidence of cis in our teaching hospital during a 23-month period.in this descriptive cross-sectional study, 76766 patients from 2009 to 2011 admitted to 17 wards of imam reza hospital in mashhad were studi...
Predicted changes in the intensity and frequency of climate extremes urge a better mechanistic understanding of the stress response of microbially mediated carbon (C) and nutrient cycling processes. We analyzed the resistance and resilience of microbial C, nitrogen (N), and phosphorus (P) cycling processes and microbial community composition in decomposing plant litter to transient, but severe,...
