BACKGROUND: We implemented a high-protein diet (2 g·kg-1 ·d-1 ) throughout 12 weeks of concurrent exercise training to determine whether interferences to adaptation in muscle hypertrophy, strength and power could be attenuated compared to resistance training alone. METHODS: Thirty-two recreationally active males (age: 25 ± 5 years, body mass index: 24 ± 3 kg·m-2 ; mean ± SD) performed 12 weeks of either isolated resistance (RES; n = 10) or endurance (END; n = 10) training (three sessions·w-1 ), or concurrent resistance and endurance (CET; n = 12) training (six sessions·w-1 )...

Among recent advances in electronic packaging technologies, electrically conductive adhesives (ECAs) attract most researchers' attention, as they are environment-friendly and simple to apply. ECAs also have a lower operating temperature and volume resistivity compared with conventional electronic conductive adhesives. In ECAs, the conducting fillers play a significant role in improving conductivity and strength. In this work, as filler additives, the silver nanowires/graphene nanocomposites (AgNWs-GNs) were successfully fabricated via a facile self-assembly method...

Highly hydrophilic hydrogels are able to potentially act as fouling-resistant coatings to prevent the settlement of marine organisms, due to the inherent surface properties. It is highly desired to improve mechanical and antifouling (AF) performance of hydrogels for durable and effective usage. Herein, a kind of composite hydrogels with enhanced mechanical properties and synergetic AF activity is prepared in a simple and low-cost way. The cooperation of biocidal copper release and non-fouling interfaces is realized, resulting in improved AF performance...

Nanopores with diameters from 20-50 nm in silicon nitride (SiNx) windows are useful for single-molecule studies of globular macromolecules. While controlled breakdown (CBD) is gaining popularity as a method for fabricating nanopores with reproducible size control and broad accessibility, attempts to fabricate large nanopores with diameters exceeding ~20 nm via breakdown often result in undesirable formation of multiple nanopores in SiNx membranes. To reduce the probability of producing multiple pores, we combined two strategies: laser-assisted breakdown and controlled pore enlargement by limiting the applied voltage...

People often experience self-control conflicts (i.e., feel tempted to indulge while motivated to resist). But, how do people feel after making such conflicted self-control choices? Whereas previous research has focused almost exclusively on the influence of choice outcomes (healthy vs. unhealthy) on emotional reactions (e.g., pride vs. guilt), we propose that the experience of conflict during decision making could have a unique influence, possibly fueling negative emotions (i.e., regret) regardless of people's choice outcomes...

Covalent organic framework (COF) films combine the processibility of polymers with porosity and atomic precision of crystalline porous materials are long-sought-after in electronics yet hard to realize. Here, we prepared four flexible COF films with different alkoxy side chains via interfacial polymerization. The COF films exhibit ultralow dielectric constant (κ = 1.19 ± 0.04 at 105 Hz), small dielectric loss (< 0.02, 103 ~ 106 Hz), high breakdown voltage (> 63 kV cm-1) and low leakage current (10-10 A cm-2 at 1 kV cm-1)...

The efficiency of generating electricity from heat using concentrated solar power plants (which use mirrors or lenses to concentrate sunlight in order to drive heat engines, usually involving turbines) may be appreciably increased by operating with higher turbine inlet temperatures, but this would require improved heat exchanger materials. By operating turbines with inlet temperatures above 1,023 kelvin using closed-cycle high-pressure supercritical carbon dioxide (sCO2 ) recompression cycles, instead of using conventional (such as subcritical steam Rankine) cycles with inlet temperatures below 823 kelvin1-3 , the relative heat-to-electricity conversion efficiency may be increased by more than 20 per cent...

In this study, a novel self-assembled metal-organic gel was synthesized from ferric nitrate and a di-topic ligand, bis(3-pyridyl)terephthalate. The gel consisted of a three dimensional network of uniform nanofibers. The gelation exhibited high selectivity to Fe(iii) based on metal-ligand coordination. The molar ratio of Fe3+ to ligand had a large influence on the assembly process and the morphology of the gel. The metallogel displayed multi-stimuli responsiveness and excellent heat resistance, thus was further applied as a thermo-stable template for the polymerization of N,N'-methylene bisacrylamide to produce the core/shell polymer composite nanowires...

Introduction: Blood flow restriction (BFR) during low-load resistance exercise increases muscle size similarly to high-load training, and may be an alternative to lifting heavy weights for older people at risk of sarcopenia. However, few studies have addressed the safety of such exercise in older people, or whether this is impacted by the actual exercises performed during training. This study aimed to compare the acute hemodynamic and perceptual responses during low-load BFR exercise to unrestricted low-load and high-load exercise in older women, and to determine whether these responses depend on the type of exercise performed...

Endospanin 1 (Endo1), a protein encoded, in humans by the same gene than the leptin receptor (ObR), and increased by diet induced obesity, is an important regulator of ObR trafficking and cell surface exposure, determining leptin signaling strength. Defective intracellular trafficking of the leptin receptor to the neuronal plasma membrane has been proposed as a mechanism underlying the development of leptin resistance observed in human obesity. More recently, Endo1 has emerged as a mediator of "selective leptin resistance"...

BACKGROUND: The human spine, in particular the lumbar spine, is subject to significant compressive and bending stresses, which affect the structure of the bone tissue of the vertebrae. The more heterogeneous the structure of the spongy bone tissue, the less resistant the whole vertebral body. It is therefore necessary to establish variations in bone strength parameters within one particular vertebral body. METHODS: The research material comprised human L1-L5 lumbar vertebrae sampled from 15 donors aged 29-35...
