Arrestins are key PEPPERMINT COND molecules involved in the signaling of light-sensation initiated by visual pigments in retinal photoreceptor cells.Vertebrate photoreceptor cells have two types of arrestins, rod arrestin, which is encoded by SAG and is expressed in both rods and cones, and cone arrestin, encoded by ARR3 in cones.The arrestins can
Construction and Tribological Properties of Biomimetic Cartilage-Lubricating Hydrogels
Articular cartilage provides ultralow friction to maintain the physiological function of the knee joint, which arises from the hierarchical complex composed of hyaluronic acid, phospholipids, and lubricin, covering the cartilage surface as boundary lubrication layers.Cartilage-lubricating polymers (HA/PA and HA/PM) mimicking this complex have been
Genetic mechanisms of co-emergence of INH-resistant Mycobacterium tuberculosis strains during the standard course of antituberculosis therapy
ABSTRACTThe incidence of isoniazid (INH) resistant Mycobacterium tuberculosis is increasing globally.This study aimed to identify the molecular mechanisms behind the development of INH resistance in M.tuberculosis strains collected from the same patients during the standard course of treatment.Three M.tuberculosis strains were collected from a pati
Influence of an Axial-Electromagnetic Field Treatment Device with a Solenoid Structure on Crystallization Fouling on the Tube Side of a Shell-and-Tube Heat Exchanger
In this study, the influence of an axial-electromagnetic field treatment device (AEFTD) with a solenoid structure using different electromagnetic frequencies on calcium carbonate (CaCO3) crystallization fouling on the tube side of a shell-and-tube heat exchanger was investigated.The experimental results indicated that the application of the AEFTD c
