Contact Sports May Alter the Brain, Scans Suggest

FRIDAY, April 20, 2018 -- There are differences in the brains of athletes who play contact sports and those who play noncontact sports, according to researchers. But they added that it isn't clear if these differences are caused by blows to the head...

In this study, the insoluble dietary fiber (IDF) and soluble dietary fiber (SDF) were obtained by enzymatic hydrolysis and lyophilization of wheat bran (Triticum aestivum L.). The physicochemical properties were to evaluated by laser diffraction, scanning electron microscopy, Fourier-transform infrared spectroscopy and X-ray diffraction. The results showed that the IDF was good at absorbing peanut oil (5.86 g/g), lard (9.63 g/g), cholesterol (4.11 mg/g in small intestine and 2.87 mg/g in stomach), sodium cholate (3.19 mg/g) and nitrite (100% at 105 min), while the SDF showed impressive DPPH, A...

In this study, new multifunctional organic-inorganic pigments were synthesized by the complexation of carboxlic azo dyes (D1, D2) with aluminum-magnesium hydroxycarbonate (LH) and were applied as colorants in ethylene-norbornene copolymer (EN). The structures of the hybrid pigments were analyzed by X-ray diffraction (XRD), secondary ion mass spectrometry (TOF-SIMS), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). X-ray diffraction revealed that the hybrid pigments had developed new crystalline structures and showed the presence of additional peaks on their diffraction patterns. Moreover, TOF SIMS c...

In this study, the characteristic of the biofilm produced on vascular and urological catheters was determined using a confocal microscopy for the most frequently involved in infections diphtheroid species. They were represented by the reference strains of Corynebacterium striatum ATCC 6940 and C. amycolatum ATCC 700207. The effect of ciprofloxacin on the biofilm produced by the antibiotic-susceptible C. striatum strain was evaluated using three concentrations of the antimicrobial agent (2 ×, 4 ×, and 6 × the MIC - the Minimum Inhibitory Concentration). The basis for the interpretation of results was the s...

Maciel, C.J. de AraújoAbstractIn this work, the microstructure and mechanical behaviour of dissimilar nickel-titanium (NiTi) shape memory alloy (SMA) and AISI 304 stainless steel (SS) thin sheets welded by micro gas tungsten arc welding (GTAW) using NiTi and Inconel 625 as filler metals were studied. The influence of a post-weld heat treatment was also elucidated. The obtained dissimilar NiTi-304SS joints were characterized by optical and scanning electronic microscopy, tensile tests and...

Publication date: 1 March 2019Source: Materials Letters, Volume 238Author(s): Zhilong Fu, Ting Liu, Xirui Kong, Yi Liu, Jie Xu, Bo Zhang, Huimin Chen, Zhaoyang ChenAbstractThe Mg-vermiculite (MVerm) with the nano-layered structure was synthesized by a facile hydrothermal method at 300 °C. The concentration of NaOH solution was found to be the most important factor for the formation of layered MVerm, and the optimal concentration was 2.05 mol/L. The structure, morphology and chemical composition of MVerm with layered structure were demonstrated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray...

CONCLUSIONS: Ultra-low-dose CT has a good detection rate for all kinds of stone, even when the fragment size is small. Only small uric acid fragments need higher energy settings in order to be detected. When the stone composition is known after surgery for urolithiasis, the most appropriate CT scan setting could be suggested by the urologist during their follow-up.

In this study, five DESs have been successfully prepared using ethylene glycol (EG) as hydrogen bond donor (HBD) with N,N‑diethylethanolammonium chloride (DAC), benzyltriphenylphosphonium chloride (BTPC), choline chloride (ChCl), methyltriphenylphosphonium bromide (MTPB) and tetra‑n‑butylammonium bromide (TBAB) as salts. The freezing point of each of the five studied DESs was measured using Differential Scanning Calorimetry (DSC) and the DES functional groups were identified using the Fourier transform infrared (FTIR) spectroscopy. Moreover, the viscosity, density, electrical conductivity and surface tension were mea...
