Methylcobalamin-containing nanofiber sheets have better neuroprotective effects than small intestinal submucosa sheets.

Postoperative adhesion around nerves sometimes results in sensory and motor dysfunctions. To prevent these disorders, we have developed an electrospun nanofiber sheet incorporating methylcobalamin (MeCbl), an active form of vitamin B12 with anti-inflammatory and neuroregenerative effects. This study aimed to investigate the neuroprotective effects of MeCbl sheets against postoperative adhesion and to compare the effects of MeCbl sheets with those of porcine small intestinal submucosa (SIS) sheets using a rat sciatic nerve adhesion model.

Of the 144 strains obtained, four novel CGPB strains were isolated and phylogenetically identified: Rhodococcus sp. AF2108, Ancylobacter sp.

Effect of balloon pulmonary angioplasty on chronic thromboembolic pulmonary hypertension: an assessment of the learning curve in a Japanese university hospital.

Balloon pulmonary angioplasty (BPA) is an innovative treatment for chronic thromboembolic pulmonary hypertension (CTEPH). We retrospectively examined the clinical outcomes and complications of BPA at Yokohama City University Hospital (YCUH) between 2012 and 2018. In 2012, we began to conduct BPA sessions in 46 patients with inoperable CTEPH; 34 completed the BPA scheme and the follow-up plan.

Usefulness of pemafibrate for non-alcoholic fatty liver disease with hypertriglyceridemia.

Aim Of The Study: Non-alcoholic fatty liver disease (NAFLD) is a pathological condition associated with inflammation owing to fat deposition in the liver. Managing hypertriglyceridemia is essential for patients with NAFLD, including treatment with pemafibrate. However, whether pemafibrate affects fat deposition in the liver and whether hypertriglyceridemia is the primary treatment target remain unclear.

Identification of specific microbiota members that induce beige fat biogenesis in response to dietary cues.

Activation of brown and beige fat biogenesis promotes metabolic health in rodents and humans, but typically requires cold exposure or pharmacological activation of β-adrenergic receptors, which may pose cardiovascular risks. Dietary intervention represents a clinically viable alternative strategy to induce beige cells and thus enhance metabolic health, though the underlying mechanisms remain poorly understood. In this study, we identified specific microbiota members in both mice and humans that promote browning of white adipose tissue (WAT) and ameliorate metabolic disorders in the context of a low-protein diet (LPD).

Conversion surgery after gemcitabine and cisplatin plus durvalumab for advanced intrahepatic cholangiocarcinoma: A case report.

Background: The combination of immune checkpoint inhibitors and chemotherapy has shown promising results for the treatment of advanced biliary tract cancer (BTC). Based on the results of the TOPAZ-1 trial, a gemcitabine and cisplatin plus durvalumab (GCD) regimen was recently approved as first-line therapy for patients with advanced BTC. However, post-GCD conversion surgery has not been previously studied.

Prognostic Value of Sarcopenia Definitions and Outcomes Consortium Criteria in Older Patients with Heart Failure.

Objectives: The Asian Working Group for Sarcopenia in 2019 (AWGS 2019) emphasized muscle mass measurements. In contrast, the Sarcopenia Definitions and Outcomes Consortium (SDOC) prioritizes functional strength and mobility. Therefore, this study aimed to compare the prognostic utility of the SDOC and AWGS 2019 criteria for all-cause mortality in older patients with heart failure.

Neudesin, a secretory protein, attenuates activation of lipopolysaccharide-stimulated macrophages by suppressing the Jak/Stat1/iNOS pathway.

Aims: Neudesin, a heme-binding protein previously identified for its neurotrophic activity, has been implicated in various physiological and pathological processes, including immune regulation. However, its role in inflammatory macrophages remains unclear. Herein, we investigated the function of neudesin in the regulation of inflammatory macrophages.

The Benefits of Early Rehabilitation for Patients With Acute Heart Failure Requiring IV Inotropic Drugs.

Objectives: The benefits of early rehabilitation for patients with acute heart failure (HF) requiring IV inotropic drugs have yet to be determined. We investigated the association between early rehabilitation and short-term clinical outcomes in patients with acute HF requiring IV inotropic drugs.

Design: Retrospective cohort study.

An 11-mer Synthetic Peptide Suppressing Aggregation of Aβ25-35 and Resolving Its Aggregated Form Improves Test Performance in an Aβ25-35-Induced Alzheimer's Mouse Model.

There is a high demand for the development of drugs against Alzheimer's disease (AD), which is related to the misfolding and aggregation of Amyloid-β (Aβ), due to the increasing number of patients with AD. In our present study, we aimed to assess the aggregation inhibitory effect of various synthetic YS-peptides on Aβ25-35 to identify an applicable peptide for clinical use for AD treatment and prevention. Suppression and aggregate resolution activities of YS-peptides against Aβ25-35 were evaluated using a Thioflavin T assay and scanning electron microscopy (SEM).

Identification of circulating microbial DNA and its association with kidney function in patients with diabetic kidney disease.

Aim: Recently, substantial studies have been accumulated to indicate the important role of gut microbiota in diabetic kidney disease (DKD). The abnormal change of bacterial-derived products could imply specific injuries or play beneficial or harmful roles in DKD progression. In this study, we examined the presence and contribution of the Klebsiella oxytoca gene in the circulation of patients with DKD.

Aims: This study aimed to develop a cardiovascular disease (CVD) risk model using data from a large occupational cohort.

Methods: A risk prediction model was developed using the routine health checkup data of 96,117 Japanese employees (84.0% men) who were 30-64 years of age and had no CVD at baseline.

Zeta Potentials of Cotton Membranes in Acetonitrile Solutions.

Solid surfaces in contact with nonaqueous solvents play a key role in electrochemistry, analytical chemistry, and industrial chemistry. In this work, the zeta potentials of cotton membranes in acetonitrile solutions were determined by streaming potential and bulk conductivity measurements. By applying the Gouy-Chapman theory and the Langmuir adsorption isotherm of ions to the experimental data, the mechanism of the electrification at the cotton/acetonitrile interface is revealed for the first time to be solely due to ion adsorption on the surface, rather than proton dissociation at the interface.

Prognostic value of Borg scale following 6-min walk test in hospitalized older patients with heart failure.

Aims: The 6-min walk test (6MWT) is a widely accepted tool for evaluating exercise tolerance and physical capacity, and the 6-min walk distance (6MWD) is an established prognostic factor in patients with heart failure (HF). However, the prognostic implications of post-6MWT dyspnoea remain unknown. We aimed to investigate the prognostic value of Borg scores after the 6MWT in patients with HF.
