Involvement of the liver-gut peripheral neural axis in nonalcoholic fatty liver disease pathologies via hepatic HTR2A.

Serotonin (5-HT) is one of the key bioamines of nonalcoholic fatty liver disease (NAFLD). Its mechanism of action in autonomic neural signal pathways remains unexplained; hence, we evaluated the involvement of 5-HT and related signaling pathways via autonomic nerves in NAFLD. Diet-induced NAFLD animal models were developed using wild-type and melanocortin 4 receptor (MC4R) knockout (MC4RKO) mice, and the effects of the autonomic neural axis on NAFLD physiology, 5-HT and its receptors (HTRs), and lipid metabolism-related genes were assessed by applying hepatic nerve blockade.

Daisaikoto improves fatty liver and obesity in melanocortin-4 receptor gene-deficient mice via the activation of brown adipose tissue.

Melanocortin 4 receptor gene-knockout (MC4R-KO) mice are known to develop obesity with a high-fat diet. Meanwhile, daisaikoto, one of Kampo medicines, is a drug that is expected to have therapeutic effects on obesity. Here, we report the efficacy of daisaikoto in MC4R-KO mice.

Delayed and Synchronous Recurrence of Breast Cancer Metastases in Multiple Organs.

The most common sites of breast cancer metastasis include the lymph nodes, bones, lungs, liver, and brain. Gastrointestinal tract metastasis is rarely seen, and hypopharyngeal metastasis is extremely rare. We herein report a case of late distant recurrence of breast cancer and synchronous metastasis to the hypopharynx, stomach, ileum, bones, and lymph nodes almost 24 years after surgery.

Establishment of a pancreatic cancer animal model using the pancreas-targeted hydrodynamic gene delivery method.

This research developed an easy-to-use, reproducible pancreatic cancer animal model utilizing pancreas-targeted hydrodynamic gene delivery to deliver human pancreatic cancer-related genes to the pancreas of wild-type rats. -induced pancreatic intraepithelial neoplasia lesions showed malignant transformation in the main pancreatic duct at 4 weeks and developed acinar-to-ductal metaplasia, which led to pancreatic ductal adenocarcinoma within 5 weeks, and the gene combination of and enhanced these effects. The repeat hydrodynamic gene delivery of  + combination at 4 weeks showed acinar-to-ductal metaplasia in all rats and pancreatic ductal adenocarcinoma in 80% of rats 1 week later.

Cyclin D1 Binding Protein 1 Responds to DNA Damage through the ATM-CHK2 Pathway.

Cyclin D1 binding protein 1 (CCNDBP1) is considered a tumor suppressor, and when expressed in tumor cells, CCNDBP1 can contribute to the viability of cancer cells by rescuing these cells from chemotherapy-induced DNA damage. Therefore, this study focused on investigating the function of CCNDBP1, which is directly related to the survival of cancer cells by escaping DNA damage and chemoresistance. Hepatocellular carcinoma (HCC) cells and tissues obtained from knockout mice were used for the in vitro and in vivo examination of the molecular mechanisms of CCNDBP1 associated with the recovery of cells from DNA damage.

Effects of a novel selective PPARα modulator, statin, sodium-glucose cotransporter 2 inhibitor, and combinatorial therapy on the liver and vasculature of medaka nonalcoholic steatohepatitis model.

Objective: Nonalcoholic steatohepatitis (NASH) is a disease entity with an increasing incidence, with involvement of several metabolic pathways. Various organs, including the liver, kidneys, and the vasculature, are damaged in NASH, indicating the urgent need to develop a standard therapy. Therefore, this study was conducted to investigate the effects of drugs targeting various metabolic pathways and their combinations on a high-fat diet (HFD)-induced NASH medaka model.

Modulation of serotonin in the gut-liver neural axis ameliorates the fatty and fibrotic changes in non-alcoholic fatty liver.

The etiology of non-alcoholic fatty liver disease (NAFLD) consists of various factors, including neural signal pathways. However, the molecular mechanisms of the autonomic neural signals influencing NAFLD progression have not been elucidated. Therefore, we examined the involvement of the gut-liver neural axis in NAFLD development and tested the therapeutic effect of modulation of this axis in this study.

Ghrelin-insulin-like growth factor-1 axis is activated via autonomic neural circuits in the non-alcoholic fatty liver disease.

Background: The correlation of the growth hormone (GH) and insulin-like growth factor-1 (IGF-1) with non-alcoholic fatty liver disease (NAFLD) has been reported in epidemiological studies. However, the mechanisms of molecular and inter-organ systems that render these factors to influence on NAFLD have not been elucidated. In this study, we examined the induction of ghrelin which is the GH-releasing hormone and IGF-1, and involvement of autonomic neural circuits, in the pathogenesis of NAFLD.

Antiprogramed cell death-1 therapy with microspheres for metastatic liver tumors.

Anti-programmed cell death-1 therapy with microspheres is an effective treatment for metastatic liver tumors.

Eosinophilic esophagitis after total gastrectomy treated with proton pump inhibitors: a case report.

Eosinophilic esophagitis (EoE) is a chronic, immune-mediated disorder in the esophagus characterized by symptoms related to esophageal dysfunction and eosinophil-predominant inflammation. EoE and Gastro Esophageal Reflux Disease (GERD) are known not to be mutually exclusive and share a complex relationship. Proton pump inhibitors (PPIs), which are generally used in the treatment of GERD, could be used to treat esophageal eosinophilia in suspected EoE.

[Unresectable combined hepatocellular-cholangiocellular carcinoma treated with transcatheter arterial chemoembolization and gemcitabine: a case study].

A 76-year-old female was referred to our hospital because of liver dysfunction. Abdominal contrasted computed tomography (CT) revealed a tumor of 7.5cm in the hepatic hilar area.

[A case of a hepatic arterial pseudoaneurysm that occurred after acute cholangitis due to choledocholithiasis].

We describe a 52-year-old male who underwent endoscopic retrograde biliary drainage for acute cholangitis associated with common bile duct stones. Endoscopic papillary balloon dilatation was performed, and the stones were removed using a balloon catheter. Simultaneously, we initiated edoxaban for portal vein thrombosis.

Clinical and pathological profile of eosinophilic gastroenteritis.

Background: Eosinophilic gastroenteritis (EoGE) can be diagnosed on the basis of histologic criteria; however, the pathology is considered to be heterogeneous. There is no consensus on the management of this enigmatic disorder with an unknown etiology.

Patients And Methods: Data for patients diagnosed with EoGE and followed up over a 1-year period were analyzed.

Successful Ombitasvir/Paritaprevir/Ritonavir Plus Ribavirin Retreatment for a Chronic Hepatitis C Genotype 2a Patient Who Relapsed after Sofosbuvir Plus Ribavirin Treatment.

The optimum retreatment strategy for chronic hepatitis C virus (HCV) patients who failed directly-acting antiviral agents (DAA)-based therapy is unknown. We herein report the outcomes of an HCV genotype (GT) 2a-infected patient with virologic failure following treatment with sofosbuvir plus ribavirin (SOF+RBV) who was successfully retreated with ombitasvir/paritaprevir/ritonavir plus ribavirin (OBV/PTV/r+RBV).

Hemodynamic Changes on Cone-Beam Computed Tomography during Balloon-Occluded Transcatheter Arterial Chemoembolization Using Miriplatin for Hepatocellular Carcinoma: A Preliminary Study.

Background/aim: Balloon-occluded transcatheter arterial chemoembolization (B-TACE) using miriplatin (MPT) is anticipated as a new strategy for hepatocellular carcinoma (HCC). This study was aimed at evaluating the hemodynamic changes with/without balloon occlusion of the hepatic artery, correlation of cone-beam CT (CBCT) pixels, and CT value after B-TACE for HCC.

Methods: A total of 52 patients with HCC, who underwent B-TACE using MPT in addition to the balloon-occluded CBCT hepatic arteriography, were studied.

Functional modulation of power-law distribution in visual perception.

Neuronal activities have recently been reported to exhibit power-law scaling behavior. However, it has not been demonstrated that the power-law component can play an important role in human perceptual functions. Here, we demonstrate that the power spectrum of magnetoencephalograph recordings of brain activity varies in coordination with perception of subthreshold visual stimuli.
