11β-Hydroxysteroid dehydrogenase type 1 (11β-HSD1) is a key enzyme involved in the conversion of cortisone to active cortisol in the liver. Elevated cortisol levels can trigger oxidative stress, inflammation, and hepatocyte damage, highlighting the importance of 11β-HSD1 inhibition as a potential therapeutic approach. This study aimed to explore the effects of INU-101, an inhibitor of 11β-HSD1, on the development of metabolic dysfunction-associated steatotic liver disease (MASLD) and fibrosis.

Hepatic dysregulation of lipid metabolism exacerbates inflammation and enhances the progression of metabolic dysfunction-associated steatotic liver disease (MASLD). STAT3 has been linked to lipid metabolism and inflammation. Jolkinolide B (JB), derived from , is known for its pharmacological anti-inflammatory and anti-tumor properties.

We report an ultraviolet (UV) photodetector with a universally transferable monolayer film with ordered hollow TiO spheres on p-GaN. After forming a TiO monolayer film by unidirectional rubbing of hollow TiO spheres on a polydimethylsiloxane (PDMS) supporting plate, we used a 5% polyvinyl alcohol (PVA) aqueous solution to transfer the film onto the target substrate. The PVA/TiO monolayer film was detached from the PDMS film and transferred to the p-GaN/AlO substrate.

In this study, we investigated the hepatoprotective and anti-fibrotic effects of zingerone, one of the active components of ginger, against carbon tetrachloride (CCl4)- and dimethylnitrosamine (DMN)-induced liver injuries in rats, respectively. Oral administration of zingerone (10 mg/kg) reduced CCl4-induced abnormalities in liver histology, serum alanine aminotransferase and aspartate aminotransferase levels, and liver malondialdehyde levels. Zingerone treatment attenuated CCl4-induced increases in inflammatory mediators, including tumor necrosis factor-α, interleukin-1β, cyclooxygenase-2, and inducible nitric oxide synthase mRNA levels.

Article Synopsis
  • The study reports that etching the surface of GaN-based green LEDs with H3PO4 solution enhances their optical and electrical properties.
  • By varying the etching time from 0 to 20 minutes, researchers were able to control the size and density of nano-sized etch pits, improving light extraction efficiency due to better photon escape angles.
  • However, excessive etching beyond 5 minutes led to increased leakage current and degraded electrical performance due to larger etch pit densities.

Various surface modifications have been applied to improve the adhesion properties of aluminum for the cap plate and sealing quality of electrolyte on Li ion batteries. In this study, we have tried to find the effective condition for the polymerization of triazine thiols (TT) on modified aluminum surfaces by anodic aluminum oxide. Characterization of polymerized films on aluminum was explored by scanning electron microscopy, X-ray photoelectron spectroscopy, and secondary ion mass spectroscopy analysis.

We report on the improvement of light extraction efficiency from GaN-based light-emitting diodes (LEDs) using Ni(1-x)Co(x)O nanoparticles (NPs) formed on the p-GaN layer. After formation of Ni(1-x)Co(x)O hemispherical lens arrays on the blue LEDs by drop-casting colloidal NPs, electroluminescence (EL) and photoluminescence (PL) measurements are conducted to investigate the electrical and optical properties. The PL and EL intensities from the blue LEDs with the Ni(1-x)Co(x)O NPs are 1.

Acute hepatic inflammation is regarded as a hallmark of early stage fibrosis, which can progress to extensive fibrosis and cirrhosis. Sinapic acid is a phenylpropanoid compound that is abundant in cereals, nuts, oil seeds, and berries and has been reported to exhibit a wide range of pharmacological properties. In this study, we investigated the anti-inflammatory effect of sinapic acid in carbon tetrachloride (CCl4)-induced acute hepatic injury in rats.

Sinapic acid is a member of the phenylpropanoid family and is abundant in cereals, nuts, oil seeds, and berries. It exhibits a wide range of pharmacological properties. In this study, we investigated the hepatoprotective and antifibrotic effects of sinapic acid on dimethylnitrosamine (DMN)-induced chronic liver injury in rats.

Background And Objectives: Although generic clopidogrel is widely used, clinical efficacy and safety between generic and original clopidogrel had not been well evaluated. The aim of this study was to evaluate the clinical outcomes of 2 oral formulations of clopidogrel 75 mg tablets in patients with coronary artery disease (CAD) undergoing drug-eluting stent (DES) implantation.

Subjects And Methods: Between July 2006 and February 2009, 428 patients that underwent implantation with DES for CAD and completed >1 year of clinical follow-up were enrolled in this study.

Accurate measurement of the volume status in hemodialysis patients is important as it can affect mortality. However, no studies have been conducted regarding volume management in cases where a sudden change of body fluid occurs, such as during puerperium in hemodialysis patients. This report presents a case in which the patient was monitored for her body composition and her volume status was controlled using a body composition monitor (BCM) during the puerperal period.

Patient with end stage renal disease have characteristics in common with heart failure patients, and volume overload in heart failure is associated with poorer outcomes. Fluid removal during the hemodialysis (HD) is the cornerstone of volume management in this population. The objective of this study is to assess the long-term prognostic effect of interdialytic fluid retention (IDFR) and its relationship with cardiovascular (CV) events in incident HD patients who newly started dialysis.

Objective: Transient receptor potential vanilloid subfamily type 1 (TRPV1), a most specific marker of the nociceptive primary afferent, is expressed in peptidergic and non-pepetidergic primary afferents innervating skin and viscera. However, its expression in sensory fibers to skeletal muscle is not well known. In this study, we studied the neurochemical characteristics of TRPV1-positive primary afferents to skeletal muscles.
