Non-cirrhotic portal fibrosis/idiopathic portal hypertension: APASL recommendations for diagnosis and management.

Since the Asian Pacific Association for the Study of the Liver (APASL) published guidelines on non-cirrhotic portal fibrosis/idiopathic portal hypertension in 2007, there has been a surge in new information, especially with the introduction of the term porto-sinusoidal vascular disorder (PSVD). Non-cirrhotic intra-hepatic causes of portal hypertension include disorders with a clearly identifiable etiology, such as schistosomiasis, as well as disorders with an unclear etiology such as non-cirrhotic portal fibrosis (NCPF), also termed idiopathic portal hypertension (IPH). This entity is being increasingly recognized as being associated with systemic disease and drug therapy, especially cancer therapy.

Myokine BDNF highly expressed in Type I fibers inhibits the differentiation of myotubes into Type II fibers.

Background: Myofibers are broadly classified as slow-twitch (Type I) and fast-twitch (Type II) fibers. These two types of myofibers coexist within the same skeletal muscle tissue, determining the contractile and metabolic properties of skeletal muscle tissue by fiber type distribution.

Methods And Results: By examining each fiber type separately, we confirmed that brain-derived neurotrophic factor (BDNF) gene is highly expressed in Type I fibers.

Reliability and utility of blood glucose levels in the periodontal pockets of patients with type 2 diabetes mellitus: a cross-sectional study.

Background: Several studies have measured gingival blood glucose (GBG) levels, but few have confirmed systematic bias using Bland-Altman analysis. This study compared the effectiveness of GBG levels with that of fingertip blood glucose (FTBG) levels using Bland-Altman and receiver operating characteristic (ROC) analyses.

Methods: A total of 15 healthy volunteers and 15 patients with type 2 diabetes were selected according to inclusion and exclusion criteria.

Effect of Cobalt Substitution on the Activation of the LiNiO Discharge Reaction.

Cobalt (Co) has been introduced to most of the practical Ni-rich layered positive electrode materials owing to its ability to stabilize the layered structure and lessen cation-mixing. However, it has been unclear whether a highly ordered structure is essential or Co addition itself has some effects. In this study, we synthesized Co-substituted LiNiO (LNO) with and without the introduction of cation-mixing to investigate the detailed effects of Co on crystal/local structures and electrochemical properties.

Visceral Fat Associated with Worsening of Recurrent Esophageal Varices in Alcoholic/Nonalcoholic Steatohepatitis-Related Liver Cirrhosis.

Background: Alcoholic steatohepatitis and nonalcoholic steatohepatitis-related liver cirrhosis (ASH/NASH-LC) are major causes of esophageal varices (EVs). However, the association between high visceral fat and exacerbation of EVs remains unclear. The aim of this study was to clarify the association of visceral fat and recurrence rate of EVs in ASH/NASH-LC and to identify independent predictors associated with recurrence.

Outcomes and Recurrence Rate of Esophageal Varices after Endoscopic Treatment in Patients with Alcoholic Cirrhosis and Viral Cirrhosis.

Background: The incidence of alcoholic liver cirrhosis (ALC) is increasing. However, few reports have focused on ALC-derived esophageal varices (EV). We retrospectively examined differences in overall survival (OS) and EV recurrence rate in patients after endoscopic injection sclerotherapy (EIS) for ALC and hepatic B/C virus liver cirrhosis (B/C-LC).

Three stepwise pH progressions in stratum corneum for homeostatic maintenance of the skin.

The stratum corneum is the outermost skin layer with a vital role in skin barrier function. It is comprised of dead keratinocytes (corneocytes) and is known to maintain its thickness by shedding cells, although, the precise mechanisms that safeguard stratum corneum maturation and homeostasis remain unclear. Previous ex vivo studies have suggested a neutral-to-acidic pH gradient in the stratum corneum.

Oral infection with Porphyromonas gingivalis augmented gingival epithelial barrier molecules alteration with aging.

Objective: Disruption of the gingival epithelial barrier is often mediated by aging or the pathogen Porphyromonas gingivalis. This study examined the combined effects of aging and P. gingivalis exposure on gingival epithelial barrier molecules.

Outcomes of Octogenarians and Nonagenarians in a Contemporary Cardiac Care Unit - Insights From 2,242 Patients Admitted Between 2019 and 2021.

The number of octo- and nonagenarians admitted to cardiac care units (CCUs) has been increasing in the context of an aging society; however, clinical details and outcomes for these patients are scarce. Data from 2,242 consecutive patients admitted to the CCU between 2019 and 2021 (age <80 years, 1,390 [62%]; octogenarians, 655 [29%]; nonagenarians, 197 [8.7%]) were reviewed using the in-hospital database for the Tokyo CCU Network.

Ingenuity pathway analysis of gingival epithelial cells stimulated with estradiol and progesterone.

Objective: Periodontal disease is a risk factor for preterm delivery, and elevated female hormone levels during pregnancy promote hormone-dependent periodontopathogenic bacterial growth and gingivitis. Although the saliva of pregnant women contains female hormones at elevated levels, their effects on the gingiva are poorly understood. Therefore, in this study, we investigated the effects of estradiol and progesterone stimulation on gingival epithelial cells via ingenuity pathway analysis.

Lack of Musashi-2 induces type IIa fiber-dominated muscle atrophy.

Skeletal muscle is a highly plastic tissue, adapting its structure and metabolism in response to diverse conditions such as contractile activity, nutrients, and diseases. Finding a novel master regulator of muscle mass and quality will provide new therapeutic targets for the prevention and treatment of muscle weakness. Musashi is an RNA-binding protein that dynamically regulates protein expression; it was originally discovered as a cell fate determination factor in neural cells.

Preparation of mechanically patterned hydrogels for controlling the self-condensation of cells.

Synthetic protocols providing mechanical patterns to culture substrate are essential to control the self-condensation of cells for organoid engineering. Here, we present a protocol for preparing hydrogels with mechanical patterns. We describe steps for hydrogel synthesis, mechanical evaluation of the substrate, and time-lapse imaging of cell self-organization.

Stable isotope-labeled carnitine reveals its rapid transport into muscle cells and acetylation during contraction.

Carnitine plays multiple roles in skeletal muscle metabolism, including fatty acid transport and buffering of excess acetyl-CoA in the mitochondria. The skeletal muscle cannot synthesize carnitine; therefore, carnitine must be taken up from the blood into the cytoplasm. Carnitine metabolism, its uptake into cells, and the subsequent reactions of carnitine are accelerated by muscle contraction.

Effects of prolonged stimulation with heated tobacco products (Ploom TECH ) on gingival epithelial cells.

Objective And Background: Heated tobacco products have recently become commercially available. These products, as well as combustible cigarettes, produce aerosols; the risk of various diseases associated with heated tobacco products may be the same or higher than that with combustible cigarettes. In this study, we examined the effect of Ploom TECH extract on gingival epithelial cells.

Effect of cerebrospinal fluid drainage pressure in descending and thoracoabdominal aortic repair: a prospective multicenter observational study.

Purpose: Cerebrospinal fluid drainage (CSFD) is recommended during open or endovascular thoracic aortic repair. However, the incidence of CSFD complications is still high. Recently, CSF pressure has been kept high to avoid complications, but the efficacy of CSFD at higher pressures has not been confirmed.

Enlargement of the Spleen Index Is a Predictor of the Occurrence of Esophageal Varices and Hepatocellular Carcinoma after Administering Direct-acting Antiviral Agents.

Objective Direct-acting antiviral agents (DAAs) can eliminate hepatitis C virus at a high rate, although the long-term incidence of portal hypertension and hepatocellular carcinoma (HCC) has not yet been elucidated. In this observational study, we clarified the predictors associated with the incidence of esophageal varices (EVs) and HCC after DAAs treatment based on ultrasound findings and blood examinations. Methods A total of 78 patients treated with DAAs were enrolled in this study.

PDGF-B secreted from skeletal muscle enhances myoblast proliferation and myotube maturation via activation of the PDGFR signaling cascade.

Myokines, secreted factors from skeletal muscle, act locally on muscle cells or satellite cells, which is important in regulating muscle mass and function. Here, we found platelet-derived growth factor subunit B (PDGF-B) is constitutively secreted from muscle cells without muscle contraction. Furthermore, PDGF-B secretion increased with myoblast to myotube differentiation.
