INTRODUCTION There are different methods of urethroplasty in hypospadias. The present study aimed to compare the repair of the urethral plate by single vs. double layer suturing. MATERIAL AND METHODS Fifteen male rabbits were assigned to the control, single layer, and double layer urethral plate suturing groups (n = 5). Experimental hypospadias was induced in the second and third groups and t...

Atomic Layer Deposition of Platinum on Strontium Titanate Surfaces Tremendous energy savings and environmental benefits are possible from improved catalysts for chemical manufacturing and emissions reduction. Breakthroughs in catalyst development will be enabled by precise methods for synthesizing nanostructured materials. Atomic layer deposition (ALD) is a thin film growth technique that is cu...

In this study, the 4-week oral toxicity and anti-cancer activity of the hexane layer of Melia azedarach L. var. japonica Makino's bark extract were investigated. We carried out a hollow fiber (HF) assay and 28- day repeated toxicity study to confirm the anti-cancer effect and safety of the hexane layer. The HF assay was carried out using an A549 human adenocarcinoma cell via intraperitoneal (IP...

This pilot study was aimed at comparing TLR7/TLR9 expression, cytoskeletal arrangement, and cell proliferation by indirect immunofluorescence in parallel lesional non skin samples of guttate psoriasis (PG) vulgaris (PV) five male patients for each group (n=10). TLR7 expression detected throughout all the epidermal compartment PV samples, while PG restricted to granular layer. TLR9 present layer...

a thin-layer chromatography method has been developed and evaluated for the separation and determination of lysine and methonine in a mixture of amino acids obtained from acid or enzyme hydrolysis of protein. the solvent systems were (a) ethanol-ether, (b) phenol-water, (c) ethyl methyl ketone-pyridine-distilled water-glacial acetic acid. procedures in all the three stages were in the same dime...

Purpose In cyclic light-reared Pde6brd10 mice, rod cell oxidative stress contributes to the degenerative phenotype. Dark rearing Pde6brd10 mice slows but does not prevent atrophy. This suggests that outer retinal oxidative stress occurs in Pde6brd10 mice independent of light exposure, a hypothesis tested in this study. Methods Mouse strains Pde6brd10 and C57Bl/6 (wild type) were dark reared u...

PURPOSE: To analysis the effects of passive smoking on the microstructure of tissues of the abdominal wall regarding microcirculation, using histopathological study of the tobacco exposed rats. METHODS: Twenty four male Wistar rats were divided in Control Group (CG = 8 animals) and Exposition Groups (EG = 16 animals). EG was exposed to cigarette smoke 4x/day for 120 days, while CG was preserv...

The system complexity, as calculated from correlation dimension, embedded in each layer and its modulation by specific inputs and general excitatory state are not yet known. The aims of present study were to estimate the system complexity across the cortical layers by analyzing intracortical EEG signals using a nonlinear analytical method, and to identify how layer-related complexity varies wit...
