Obesity is associated with insulin resistance in skeletal muscle; accordingly, weight loss dramatically improves action. We sought to identify molecular remodeling of muscle commensurate that could explain improvements Muscle from morbidly obese women was studied before and after gastric bypass surgery. Gastric surgery significantly reduced body mass by approximately 45% improved then assessed mRNA profiles using a stringent statistical analysis (statistical concordance three probe set...

Ultra-high-performance fibre reinforced concrete (UHPFRC) exhibits remarkable compressive strength and ductility which, when applied to structural members, enable significant reduction of the cross-section. However, very low water-to-binder ratio high fineness admixture used for fabrication UHPFRC provoke large shrinkage strain at early age. If such is restrained by form or internal reinforcement, may become highly vulnerable occurrence cracks caused subsequent section. Therefore, this study...

OBJECTIVES Sasang Constitution is a traditional Korean medical system that classifies individuals into four types, Taeyangin, Taeeumin, Soyangin, and Soeumin, based on physical psychological traits. widely used for disease prevention treatment, emphasizing the potential of personalized healthcare. However, concerns about accuracy reliability diagnostic tools like Questionnaire Classification II (QSCC II) persist. This study investigates impact an 8-week lifestyle modification classification...

This study aimed to clarify the pure synergistic effect of an adequate protein intake (1.5 g/kg body weight/day) and resistance exercise (RE) on muscle strength, composition, metabolic markers in sedentary adults, excluding confounders arising from excessive or impaired turnover. A double-blind randomized controlled trial was performed apparently healthy adult participants (n = 34). RE for 4 weeks placebo (PLA-EX, n 17) whey supplement groups (PRO-EX, 17).

Modeling of low severity soft-tissue injury due to unwanted collisions a robot in collaborative settings is an important aspect be treated safe physical Human-Robot Interaction (pHRI). Up now, safety evaluations for pHRI were mainly conducted by using criteria related with impact forces and head accelerations. These indicate severe the robotics context leave out such as contusions lacerations. However, design intrinsically safer arm, reliable evaluation collision between human that based on...

This study investigated the effects of expansive agent (EA) and shrinkage-reducing (SRA) on mechanical shrinkage properties ultra-high-performance concrete. Along with a reference specimen, work considered five different specimens ratios SRA (1% 2%), EA (5% 7·5%) combination 1% 7·5% EA. The test results revealed that compressive strength varied inclusion EA, while tensile decreased according to admixing free strain was obviously reduced by including specimen showed lowest strain. inner steel...

Background: Hypertension is common in patients with metabolic syndrome (MS), and it an important risk factor for cardiovascular-related morbidity mortality. Compared to moderate-intensity continuous training (MICT), high-intensity interval (HIIT) considered a time-efficient exercise strategy cardiometabolic health. We compared the effects of HIIT MICT on epicardial fat thickness (EFT) endothelial function hypertensive MS. Methods: In total, 34 participants MS (mean age: 50.9 ± 7.9 years)...

In recent years, collision safety has been one of the most important issues for service robots. To ensure assurance, a passive compliance method is preferred to an active because it can provide faster and more reliable responses dynamic collision. Since both positioning accuracy are equally important, robot arm should have very low stiffness when subjected force greater than causing human injury, but maintain high otherwise. order realize these ideal features, novel safe joint mechanism...

Systemic oxidative stress plays a role in many degenerative diseases. Although regular physical activity has been known as the most effective nonpharmacological intervention to alleviate stress, beneficial effect varies between individuals. We investigated whether NADPH oxidase p22phox gene C242T and A640G polymorphisms are associated with systemic level response exercise training (ExTr). Fifty-nine sedentary middle-aged older Caucasians relatively high cardiovascular disease risk factors...
