Tannic acid modified antifreezing gelatin organohydrogel for low modulus, high toughness, and sensitive flexible strain sensor.

Current hydrogel strain sensors have met assorted essential requirements of wearing comfort, mechanical toughness, and strain sensitivity. However, an increment in the toughness of a hydrogel usually leads to an increase in elastic moduli that could be unfavorable for wearing comfort. In addition, traits of biofriendly and sustainability require synthesis of the hydrogels from natural polymer-based networks.

Communication and Cooperation Between the Medical Academy, Medical Association, and Local Government: Health Counseling Program After Recovery From Coronavirus Disease 2019 (COVID-19) in Daegu.

We are currently experiencing the disaster of the COVID-19 pandemic. Since the first case of Coronavirus disease 2019 (COVID-19) was confirmed in South Korea on January 20, the number of COVID-19 cases in South Korea has been rapidly increasing until early March due to a local spread in Daegu, which is one of the eight metropolitan cities in South Korea with a population of 2.5 million.

Transparent Molecular Adhesive Enabling Mechanically Stable ITO Thin Films.

With rapid advances in flexible electronics, transparent conductive electrodes (TCEs) have also been significantly developed as alternatives to the conventional indium tin oxide (ITO)-based material systems that exhibit low mechanical flexibility. Nanomaterial-based alternating materials, such as graphene, nanowire, and nanomesh, exhibit remarkable properties for TCE-based applications, such as high electrical conductivity, high optical transparency, and high mechanical stability. However, these nanomaterial-based systems lack scalability, which is a key requirement for practical applications, and exhibit a size-dependent property variation and inhomogeneous surface uniformity that limit reliable properties over a large area.

Sarcopenia and Muscle Aging: A Brief Overview.

The world is facing the new challenges of an aging population, and understanding the process of aging has therefore become one of the most important global concerns. Sarcopenia is a condition which is defined by the gradual loss of skeletal muscle mass and function with age. In research and clinical practice, sarcopenia is recognized as a component of geriatric disease and is a current target for drug development.

Scaffold-supported extracellular matrices preserved by magnesium hydroxide nanoparticles for renal tissue regeneration.

Fibroblast-derived extracellular matrix (fECM)-supported scaffolds made up of poly(lactic-co-glycolic acid) were prepared with the enhanced preservation of ECM components by composites with magnesium hydroxide nanoparticles (MH NPs), and were applied for the renal tissue regeneration. MH NP utilization resulted in an increased ECM protein amount, decreased scaffold degradation, and surface hydrophilic modification. These effects were correlated with the improved adhesion and viability of renal proximal tubule epithelial cells on the scaffold.
