The purpose of this study was to investigate the clinical role of proton magnetic resonance spectroscopy (1H-MRS) in the diagnosis of acute cerebral infarction. Using databases available at the Fifth Affiliated Hospital of Zhengzhou University (Zhengzhou, China), the medical records of 47 patients with acute cerebral infarction treated between April 2010 and March 2012 were retrospectively revi...

Renal tubular lysosomal enzyme activities like alanine aminopeptidase (AAP) and N-acetyl-β-D-glucosaminidase (NAG) have been shown to increase in patients developing diabetic nephropathy and nephrosclerosis. This study aimed to determine the activities of N-acetyl-β-D-glucosaminidase and alanine aminopeptidase and albumin concentration in urine samples of patients with type 2 diabetes. One hund...

Recent data suggest that DKA may contribute to cognitive impairment in children with type 1 DM. We measured the NAA/Cr ratio in a teenager during and following 2 separate episodes of DKA without clinically apparent cerebral edema. The NAA/Cr ratio decreased during DKA and improved following recovery. However, the NAA/Cr value was lower after the second episode of DKA (1.76) than after the first...

In this paper, Wavelet Transform, Fractional Fourier Transform (FrFT) and Fractional Cosine Transform (FrCT) are compared using Mean Square Error (MSE) and Peak signal-toNoise Ratio (PSNR) in the field of image compression. Wavelet provides better MSE and PSNR at lower Compression Ratio (CR), whereas FrFT provides good result at higher CR and FrCT provides same results as that of Wavelet at hig...

Cr-doped AlN thin fi lms were epitaxially grown on Al2O3(001) substrates at lowtemperature by reactivemagnetron sputtering,and their magnetic properties were investigated. Extensive x-ray diffraction studies indicated that the fi lms have a wurtzite-type hexagonal structure and are (001) oriented, with an epitaxial relationship of the [100] direction of the fi lms along the [110] direction of A...

The preparation of nanocellulose via Cr(NO3)3-assisted sulfuric acid hydrolysis was optimized using response surface methodology (RSM). The experiment was performed using a five-level, four-factor central composite design coupled with RSM in order to optimize nanocellulose crystallinity and product yield. Four factors were evaluated for the preparation of nanocellulose: (1) reaction temperature...

Cr (III) removal from aqueous solutions by sorption in a fixed bed column filled with alizarin S impregnated hemp fibers has been studied. The effect of the initial metal ion concentration on the Cr (III) sorption process was investigated and the experimental breakthrough curves were obtained. The breakthrough time and saturation time decreased from 110 min to 80 min and from 300 min to 160 min...

PURPOSE To investigate the safety of five types of antiglaucoma prostaglandin analog ophthalmic formulations, and to clarify their differences in accordance with contained additives (preservatives and surface-active agents). METHODS THE FOLLOWING FIVE TYPES OF OPHTHALMIC SOLUTIONS AND THREE TYPES OF ADDITIVES WERE INVESTIGATED: latanoprost (Xalatan(®); latanoprost), tafluprost (Tapros(®); taf...

background urinary tract infection (uti) is common in children. uti with or without vesico-ureteral reflux (vur) may result in renal scarring. severe renal scarring impairs renal function and may result in hypertension, renal insufficiency, and end stage renal disease requiring dialyses or transplantation. beta 2 micro-globulin (ß2mg) is a low molecular weight protein freely filtered by the glo...
