In addition to chemical compositions, physical properties of scaffolds, such as pore size, can also influence vascularization within the scaffolds. A larger pore has been shown to improve host vascular tissue invasion into scaffolds. However, the influence of pore sizes on vascularization by endothelial cells directly encapsulated in hydrogels remains unknown. In this study, micro-cavitary hydrogels with different pore sizes were created in gelatin-methacrylate hydrogels with dissolvable gelatin microspheres (MS) varying in sizes...

Lung’s own properties make that nutritional support, besides covering the requirements can modulate its infl ammatory response. Lung tissue has a low glucose stock. Fatty acids are the main energy producer of type II pneumocytes, which use them in order to form phospholipids, essential for surfactant whose creation and release decrease in acute lung injury (ALI). Glutamine is a good substratum for endocrine cells and type II pneumocytes. Due to high nutritional risk, it is important its assessments in disorders as COPD and acute respiratory distress syndrome (ADRS)...

BACKGROUND: Reductions in postprandial lipemia have been observed following aerobic exercise of sufficient energy expenditure. Increased excess post-exercise oxygen consumption (EPOC) has been documented when comparing high- versus low-intensity exercise. The contribution of EPOC energy expenditure to alterations in postprandial lipemia has not been determined. OBJECTIVE: The purpose of this study was to evaluate the effects of low- and high-intensity exercise on postprandial lipemia in healthy, sedentary, overweight and obese men (43 <u>+</u> 10 years; 31...

Electrochemical promotion of catalysis (EPOC) has been shown to accelerate the rate of many heterogeneous catalytic reactions; however, it has rarely been reported in low-temperature aqueous electrochemical reactions. Herein, we report a significant EPOC effect for the CO2 reduction to generate formate over Pd nanoparticles (NPs) in a 1 M KHCO3 aqueous solution. By applying a negative potential over differently-sized Pd NPs, the rate of formate production is greatly improved as compared to that at an open-circuit voltage, with a rate enhancement ratio ranging from 10 to 143...

BACKGROUND: As in other areas of health delivery, there is a need to ensure that end-of-life care is guided by patient centred research. A systematic review was undertaken to examine the quantity and quality of data-based research aimed at improving the (a) processes and (b) outcomes associated with delivering end-of-life care in hospital settings. METHODS: Medline, EMBASE and Cochrane databases were searched between 1995 and 2015 for data-based papers. Eligible papers were classified as descriptive, measurement or intervention studies...

Transcranial direct current stimulation (tDCS) of the cerebellum is emerging as a novel non-invasive tool to modulate the activity of the cerebellar circuitry. In a single blinded study, we applied anodal tDCS (atDCS) of the cerebellum to assess its effects on brain entropy and brain rhythms during self-paced sequential finger movements in a group of healthy volunteers. Although wearable electroencephalogram (EEG) systems cannot compete with traditional clinical/laboratory set-ups in terms of accuracy and channel density, they have now reached a sufficient maturity to envision daily life applications...

This study compared the performance of a low-cost wireless EEG system to a research-grade EEG system on an auditory oddball task designed to elicit N200 and P300 ERP components. Participants were 15 healthy adults (6 female) aged between 19 and 40 (M = 28.56; SD = 6.38). An auditory oddball task was presented comprising 1,200 presentations of a standard tone interspersed by 300 trials comprising a deviant tone. EEG was simultaneously recorded from a modified Emotiv EPOC and a NeuroScan SynAmps RT EEG system...

PURPOSE: The aim of the present study was to compare the energy expenditure (EE) during and after two treadmill protocols, high-intensity interval training (HIIT) and moderate continuous training (CONT), in young adult men. METHODS: The sample was comprised by 26 physically active men aged between 18 and 35 years engaged in aerobic training programs. They were divided into two groups: HIIT (n = 14) which performed eight 20 s bouts at 130% of the velocity associated with the maximal oxygen consumption on a treadmill with 10 s of passive rest, or CONT (n = 12) which performed 30 min running on a treadmill at a submaximal velocity equivalent to 90-95% of the heart rate associated with the anaerobic threshold...

The return towards resting homeostasis in the post-exercise period has the potential to represent the internal training load of the preceding exercise bout. However, the relative potential of metabolic and autonomic recovery measurements in this role has not previously been established. Therefore the aim of this study was to investigate which of 4 recovery measurements was most closely associated with Borg's Rating of Perceived Exertion (RPE), a measurement widely acknowledged as an integrated measurement of the homeostatic stress of an exercise bout...

INTRODUCTION: To counteract the winter activity deficit, we set out to analyze cardiorespiratory and metabolic responses of two high intensity training (HIT) protocols during alpine skiing (AS), cross-country skiing (XCS) and indoor cycling (IC) and the effects of sex, age and fitness level in this comparison. METHODS: Nineteen healthy subjects (two age and fitness groups, both sexes) performed AS, XCS, and IC with measurements of oxygen uptake (VO2), energy expenditure (EE), heart rate (HR), lactate, blood glucose and rate of perceived exertion, determined during 4-min of continuous high intensity (HITc: 90% HRmax for XCS and IC or short turn skiing during AS) or 10-min intermittent HIT [HITint: 5x1' high intensity (>90% HRmax or short turn skiing), 1' active recovery]...

Acute exposure to crude oil polycyclic aromatic hydrocarbons (PAH) can severely impair cardiorespiratory function and swim performance of larval fish; however, the effects of acute oil exposure on later life stages and the capacity for subsequent recovery is less clear. Red drum (Sciaenops ocellatus) is an economically important apex predator native to the Gulf of Mexico, which was directly exposed to the 2010 Deep Water Horizon (DWH) oil spill. Here we examine impact and recovery of young adult red drum from exposure to concentrations of 0, 4...

BACKGROUND: Changing population demographics have led to an increasing number of functionally dependent older people who require care and medical treatment. In many countries, government policy aims to shift resources into the community from institutional care settings with the expectation that this will reduce costs and improve the quality of care compared. OBJECTIVES: To assess the effects of long-term home or foster home care versus institutional care for functionally dependent older people...

ISSUES: Indigenous peoples of Australia, New Zealand, Canada and the United States experience a disproportionately high burden of harms from substance misuse. Research is therefore required to improve our understanding of substance use in Indigenous populations and provide evidence on strategies effective for reducing harmful use. APPROACH: A search of 13 electronic databases for peer-reviewed articles published between 1993 and 2014 focusing on substance use and Indigenous peoples of Australia, New Zealand, Canada and the United States...

Brain-computer interfaces (BCI) provide means of communications and control, in assistive technology, which do not require motor activity from the user. The goal of this study is to promote classification of two types of imaginary movements, left and right hands, in an EMOTIV cap based system, using the Naïve Bayes classifier. A preliminary analysis with respect to results obtained by other experiments in this field is also conducted.
