BACKGROUND The aim of this study was to investigate the incidence of contrast-induced nephropathy (CIN) according to renal function in patients with or without proteinuria after cardiac catheterization in Japan. METHODS AND RESULTS: We conducted a multicenter prospective observational study involving 27 hospitals from all over Japan, which enrolled 906 patients with cardiac catheterization. CIN...

Background—The RenalGuard System, which creates high urine output and fluid balancing, may be beneficial in preventing contrast-induced acute kidney injury. Methods and Results—The Renal Insufficiency After Contrast Media Administration Trial II (REMEDIAL II) trial is a randomized, multicenter, investigator-driven trial addressing the prevention of contrast-induced acute kidney injury in high-r...

Chitinase production by a terrestrial Streptomyces sp. ANU 6277 was studied under sub-merged fermentation. Chitinase production started after 24 h of incubation and reached maximum levels after 60 h of cultivation. A high level of chitinase activity was observed in the culture medium with pH 6 at 35°C. Culture medium amended with 1% chitin was found to be suitable for maximum production of chit...

A number of recent studies have indicated the potential of ultrasound contrast agent imaging at high ultrasound frequencies. However, the acoustic properties of microbubbles at frequencies above 10 MHz remain poorly understood at present. In this study we characterize the high frequency attenuation properties of (1) BR14, (2) BR14 that has been mechanically filtered (1 and 2 microm pore sizes) ...

The Addi-Chek (filtration; Millipore Corp., Bedford, Mass.) and BACTEC (radiometric detection of growth in culture media; Johnston Laboratories, Inc., Towson, Md.) systems were compared with the 10-ml culture (centrifugation) method for the recovery of microorganisms from peritoneal dialysate collected from patients with clinical evidence of peritonitis and containing greater than or equal to 2...

Abstract Laboratory tests and column were carried out in a waterwoks to investigate the removal of short- long-chain PFAS using activated carbon filtration ion exchange treatment. For all adsorbents, sorption affinity short-chain per- polyfluoroalkyl carboxylic acids (PFCA) was significantly lower than that or sulfonic (PFSA). In PFAS-polluted groundwater matrix, PFCA PFBA PFPeA could only be s...

For the isolation and cultivation of Legionella pneumophila from tap water in hospitals, we compared different media and selection techniques. A second part of the study compared the L. pneumophila yields from different water samples at identical sites. A total of 210 water samples (500 ml each) were collected from two selected sites in each of 21 hospitals. Warm water samples were collected af...

The incidence of acute kidney injury induced by contrast media (CI-AKI) is the third cause of AKI in hospitalized patients. Contrast media cause relevant alterations both in renal hemodynamics and in renal tubular cell function that lead to CI-AKI. The vasoconstriction of intrarenal vasculature is the main hemodynamic change induced by contrast media; the vasoconstriction is accompanied by a ca...

stormwater represents one of the least researched forms of wastewater in environmental science. contaminated industrial stormwater, that is stormwater generated by runoff from industrial sites such as refineries, smelters and mine sites, is even less well understood. however, contaminated industrial stormwater can have damaging environmental impacts because it generally occurs in sudden bursts ...

Permeation grouting estimation is important for the design of engineering. Filtration effects and rheological behavior play a key role in permeation diffusion cement-based grouts. To better understand effect filtration grout on mechanism, one-dimensional injections sand columns under constant flow rate were performed by self-developed experimental procedure. Experimental results showed that the...
