Background: Recent research demonstrated that symmetry of corticomotor drive to paretic and nonparetic plantarflexor muscles are related to the biomechanical ankle moment strategy that individuals with chronic stroke used to achieve their greatest walking speeds. Rehabilitation strategies that promote corticomotor balance could potentially improve post-stroke walking mechanics and enhance functional ambulation. Objective: To 1) test the effectiveness of a single session of gait training using functional electrical stimulation (FES) to improve plantarflexor corticomotor symmetry and plantarflexion ankle moment symmetry and 2) determine if changes in corticomotor symmetry relate to changes in ankle moment symmetry within the session...

A well-managed chemical nitrogen (N) fertilization practice combined with treated swine slurry (TSS) is necessary to improve sustainability and N use efficiency in rice farming. However, little is known about the fate of N derived from chemical N fertilizer with and without TSS in paddy soil-plant systems. The objectives of this study were (1) to estimate the contribution of applied N fertilizer to N turnover in rice paddy soil with different N fertilization practices that were manipulated by the quantity of treated swine slurry and chemical N fertilizer (i...

Point-Spread Function (PSF) modelling offers the capability to account for resolution degrading phenomena within the PET reconstruction framework. PSF modelling improves resolution and enhances contrast, but at the same time significantly alters image noise properties and induces edge overshoot effect. Thus, studying the effect of PSF modelling on quantitation task performance can be very important. Frameworks explored in the past involve a dichotomy of PSF vs. no-PSF modelling. By contrast, the present work focuses on quantitative performance evaluation of standard uptake value (SUV) PET images, while incorporating a wide spectrum of PSF models, including those that under- and over-estimate the true PSF, for the potential of enhanced quantitation of standardized uptake values (SUVs)...

Herein, we describe engineered superparamagnetic iron oxide nanoparticles (IONPs) as platform materials for enhanced uranyl (UO22+) sorption and separation processes under environmentally relevant conditions. Specifically, monodispersed 8-25 nm iron oxide (magnetite, Fe3O4) nanoparticles with tailored organic acid bilayered coatings have been systematically evaluated and optimized to bind, and thus remove, uranium, from water. The combined non-hydrolytic synthesis and bilayer phase transfer material preparation methods yield highly uniform and surface tailorable IONPs, which allow us to directly evaluate the size-dependent and coating-dependent sorption capacities of IONPs...

This study investigated the independent roles of biofilm and external power supply for volatile fatty acids (VFAs) degradation and methane production in the microbial electrolysis cell (MEC). Reactors were operated in fed-batch mode in the presence of graphite felt(GF) or titanium-rod (Ti) as electrodes, in open circuit (OC, without applied voltage) or closed circuit (CC) conditions, i.e. R1 (Ti+CC), R2 (GF+CC) and R3 (GF+OC). The first-order kinetic analysis of acetate degradation indicated that the presence of GF biofilm and applied voltage in R2 improved the acetate degradation rate by 23% as compared to R1, while it was only 7% increment in R3 with GF biofilm...

Protein hydrolysates (PH) are rich sources of proteins that supply the need of exercising muscles. PHs are enriched in di- and tripeptides and are better than free amino acids or intact proteins when muscle anabolic effect is considered. Digestion, absorption and muscle uptake of amino acids are faster and more efficient when PH is ingested in comparison to the respective intact protein. PHs not only enhance endurance in high intensity exercise regimen, but also help in faster post-exercise recovery of muscle by promoting glycogen synthesis, although the latter effect requires more convincing evidence...

An improved microextraction method is proposed on the basis of ultrasound-assisted surfactant-enhanced emulsification and solidification of a floating organic droplet procedure combined with high performance liquid chromatography for the preconcentration and quantification of alprazolam (ALP) and chlordiazepoxide (CHL) present in a number of human serum samples. Several parameters affecting the extraction efficiency were investigated by the Plackett -Burman factorial design as the screening design. Then the response surface methodology based on the Box-Behnken design was used to optimize the effective parameters in the proposed procedure...

Azadirachta indica has been used for its medicinal properties since time immemorial. Herbal medicines which are prepared using this medicinal tree are utilized to treat various diseases and disorders. No reports are available for marker-based standardization of these herbal medicines prepared from leaves of A. indica. Also existing HPLC methods for determination quercetin-3-O-β-d-glucoside are time consuming. There is an obvious need for development of new HPLC method for quantification of quercetin-3-O-β-d-glucoside which is fast enough to carry out analysis in stipulated time period...

The ability of the parasympathetic nervous system to flexibly adapt to changes in environmental context is thought to serve as a physiological indicator of self-regulatory capacity, and deficits in parasympathetic flexibility appear to characterize affective disorders such as depression. However, whether parasympathetic flexibility (vagal withdrawal to emotional or environmental challenges such as sadness, and vagal augmentation during recovery from sadness) could facilitate the effectiveness of adaptive affect regulation strategies is not known...

The effectiveness of water flooding oil recovery depends to an important extent on the competitive wetting of oil and water on the solid rock matrix. Here, we use macroscopic contact angle goniometry in highly idealized model systems to evaluate how brine salinity affects the balance of wetting forces and to infer the microscopic origin of the resulting contact angle alteration. We focus in particular on two competing mechanisms debated in the literature, namely double layer expansion and divalent cation bridging...

BACKGROUND Surgery remains the mainstay of gastric cancer treatment. It is, however, associated with a relatively high risk of perioperative complications. The use of laparoscopy and the Enhanced Recovery After Surgery (ERAS) protocol allows clinicians to limit surgically induced trauma, thus improving recovery and reducing the number of complications. The aim of the study is to present clinical outcomes of patients with gastric cancer undergoing laparoscopic gastrectomy combined with the ERAS protocol. MATERIAL AND METHODS Fifty-three (21 female/32 male) patients who underwent elective laparoscopic total gastrectomy due to cancer were prospectively analyzed...
