Biomimetic coatings to increase endothelialization of blood-contacting materials in biomedical devices are promising to improve the biocompatibility of these devices. Although a stable extracellular matrix protein coating on a biomaterial's surface is a prerequisite for endothelial cell attachment, it also stimulates platelet adhesion. Therefore, antithrombotic additives, such as nitric oxide d...

In this study, the ability of lithium nitrite and amino alcohol inhibitors to provide corrosion protection to reinforcing steel was investigated. Two types of specimens-reinforcing steel and a reinforced concrete prism that were exposed to chloride ion levels resembling the chloride attack environment-were prepared. An autoclave accelerated corrosion test was then conducted. The variables teste...

nitrite is responsible for some characteristics of cured meat products such as color, flavor and suppressing the outgrowth and production of toxin from clostridium botulinum. despite all of its desired properties, nitrite is responsible for the formation of carcinogenic n-nitrosamine. in this study, nitrite-free and low-nitrite meat curing systems were developed to eliminate or reduce nitrite f...

Objective: Urinary tract infection (UTI) is common in children. Urine culture the gold standard method for diagnosing urine but it takes more than 48 h to give results. The objective evaluate diagnostic ability of modified nitrite test as a rapid screening diagnosis UTI Methods: An observational and cross-sectional study was conducted tertiary care hospital Udaipur over period 1 year. Children ...

The value of the one minute leucocyte esterase-nitrite chemical strips as a screening procedure for detecting appreciable levels of pyuria and bacteriuria was assessed by comparison with microscopy and culture results. The likelihood that a negative leucocyte esterase result indicated less than 10 white cells/cu mm by microscopy (the negative predictive value), was 90.1% and that a negative nit...

The value of the one minute leucocyte esterase-nitrite chemical strips as a screening procedure for detecting appreciable levels of pyuria and bacteriuria was assessed by comparison with microscopy and culture results. The likelihood that a negative leucocyte esterase result indicated < 10 white cells/cu mm by microscopy (the negative predictive value), was 90 1% and that a negative nitrite res...

UTI is the most common hospital acquired infections, accounting for 35% in hospitalized patients. Early diagnosis and prompt treatment of UTI in CKD patients is necessary to prevent grievous complications. The objective of this study is to determine diagnostic accuracy of multi dipstick tests for detecting UTI in CKD population and study spectrum of UTI in CKD. CKD patients attending Nephrology...

Objective To investigate whether the urine dipstick screening test can be used to predict urine culture results. Methods A retrospective study conducted between January and December 2014 based on data from 8,587 patients with a medical order for urine dipstick test, urine sediment analysis and urine culture. Sensitivity, specificity, positive and negative predictive values were determined and...
