Urinary titin reflects the severity of walking ability, muscle strength, and muscle and cardiac damage in patients with Becker muscular dystrophy.

Background: Becker muscular dystrophy (BMD) is a dystrophinopathy caused by a pathological variant of the DMD gene. Urinary titin, a degradation product of the giant protein titin present in muscle sarcomeres, has been used as a biomarker to reflect muscle degradation in Duchenne muscular dystrophy, a more severe dystrophinopathy. However, the clinical significance of urinary titin levels in BMD remains unclear.

Transileocolic Portal Vein Embolization Increases Remnant Liver Volume After Major Hepatectomy.

Background/aim: Transileocolic portal vein embolization (TIPE) may reduce the risk of liver failure after massive hepatectomy. However, convincing evidence of its usefulness in this regard is yet to be reported. Therefore, this study aimed to investigate the use of TIPE after massive hepatectomy.

Severe cardiac and skeletal manifestations in DMD-edited microminipigs: an advanced surrogate for Duchenne muscular dystrophy.

Duchenne muscular dystrophy (DMD) is an intractable X-linked muscular dystrophy caused by mutations in the DMD gene. While many animal models have been used to study the disease, translating findings to humans has been challenging. Microminipigs, with their pronounced physiological similarity to humans and notably compact size amongst pig models, could offer a more representative model for human diseases.

Efficacy and Tolerability of Ivabradine for Cardiomyopathy in Patients with Duchenne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) is an intractable X-linked myopathy caused by dystrophin gene mutations. Patients with DMD suffer from progressive muscle weakness, inevitable cardiomyopathy, increased heart rate (HR), and decreased blood pressure (BP). The aim of this study was to clarify the efficacy and tolerability of ivabradine treatment for DMD cardiomyopathy.

Association between non-alcoholic fatty liver disease and subclinical left ventricular dysfunction in the general population.

Aims: Emerging evidence suggests an association between non-alcoholic fatty liver disease (NAFLD) and heart failure (HF). We investigated the relationship between NAFLD and left ventricular (LV) functional remodelling in a general population sample without overt cardiac and liver disease.

Methods And Results: We included 481 individuals without significant alcohol consumption who voluntarily underwent an extensive cardiovascular health check.

Ivabradine ameliorates cardiomyopathy progression in a Duchenne muscular dystrophy model rat.

Duchenne muscular dystrophy (DMD) is an X-linked recessive myopathy caused by dystrophin mutations. Inevitable progressive cardiomyopathy is a current leading cause of premature death although respiratory management has improved the prognosis of patients with DMD. Recent evidence shows that reducing the heart rate is expected as one of the promising strategies for heart failure treatment, but administering a sufficient dose of β-blocker for patients with DMD with tachycardia is difficult because of their low blood pressure (BP).

Extracting higher-conductivity designs for solid polymer electrolytes by quantum-inspired annealing.

Data-driven optimal structure exploration has become a hot topic in materials for energy-related devices. However, this method is still challenging due to the insufficient prediction accuracy of material properties and large exploration space for candidate structures. We propose a data trend analysis system for materials using quantum-inspired annealing.

Quantum Annealing Boosts Prediction of Multimolecular Adsorption on Solid Surfaces Avoiding Combinatorial Explosion.

Quantum annealing has been used to predict molecular adsorption on solid surfaces. Evaluation of adsorption, which takes place in all solid surface reactions, is a crucially important subject for study in various fields. However, predicting the most stable coordination by theoretical calculations is challenging for multimolecular adsorption because there are numerous candidates.

Immunomodulatory amnion-derived mesenchymal stromal cells preserve muscle function in a mouse model of Duchenne muscular dystrophy.

Background: Duchenne muscular dystrophy (DMD) is an incurable genetic disease characterized by degeneration and necrosis of myofibers, chronic inflammation, and progressive muscle weakness resulting in premature mortality. Immunosuppressive multipotent mesenchymal stromal cell (MSC) therapy could be an option for DMD patients. We focused on amnion-derived mesenchymal stromal cells (AMSCs), a clinically viable cell source owing to their unique characteristics, such as non-invasive isolation, mitotic stability, ethical acceptability, and minimal risk of immune reaction and cancer.

Asymptomatic myocardial infarction in a patient with myotonic dystrophy type 1.

Unlabelled: Myotonic dystrophy type 1 (DM1) displays a wide range of cardiac manifestations, including conduction system disturbances, arrhythmias, and cardiomyopathy. As a result of progressive myocardial injury and fibrosis, patients with DM1 frequently show electrocardiogram (ECG) abnormalities which sometimes cannot be differentiated from myocardial ischemia. Even in DM1 cases with ECG findings indicative of coronary artery disease, coronary angiography and coronary computed tomography often demonstrate intact coronary arteries.

Human Placental Extract Delays In Vitro Cellular Senescence through the Activation of NRF2-Mediated Antioxidant Pathway.

Senescent cells accumulate in the organs of aged animals and exacerbate organ dysfunction, resulting in age-related diseases. Oxidative stress accelerates cellular senescence. Placental extract, used in the alleviation of menopausal symptoms and promotion of wound healing and liver regeneration, reportedly protects against oxidative stress.

Ligation of left gastric vein may cause delayed gastric emptying after pancreatoduodenectomy: a retrospective study.

Background: This study aimed to determine which running pattern of the left gastric vein (LGV) is most frequently ligated in subtotal stomach-preserving pancreatoduodenectomy (SSPPD) and how LGV ligation affects delayed gastric emptying (DGE) after SSPPD.

Methods: We retrospectively analysed 105 patients who underwent SSPPD between January 2016 and September 2021. We classified the running pattern of LGV as follows: type 1 runs dorsal to the common hepatic artery (CHA) or splenic artery (SpA) to join the portal vein (PV), type 2 runs dorsal to the CHA or SpA and joins the splenic vein, type 3 runs ventral to the CHA or SpA and joins the PV, and type 4 runs ventral to the CHA or SpA and joins the SpV.

A medium-chain triglyceride containing ketogenic diet exacerbates cardiomyopathy in a CRISPR/Cas9 gene-edited rat model with Duchenne muscular dystrophy.

Duchenne muscular dystrophy (DMD) is an X-linked recessive myopathy caused by dystrophin mutations. Although respiratory management has improved the prognosis of patients with DMD, inevitable progressive cardiomyopathy is a current leading cause of premature death. Recently, we showed that a medium-chain triglyceride containing ketogenic diet (MCTKD) improves skeletal muscle function and pathology in a CRISPR/Cas9 gene-edited rat model with DMD.

Human placental extract activates a wide array of gene expressions related to skin functions.

As skin aging is one of the most common dermatological concerns in recent years, scientific research has promoted treatment strategies aimed at preventing or reversing skin aging. Breakdown of the extracellular matrix (ECM), such as collagen and elastin fibers, in the skin results in decreased skin elasticity and tension. Cutaneous cells, especially fibroblasts in the dermis layer of the skin, mainly produce ECM proteins.

Safety and effectiveness of mepolizumab therapy in remission induction therapy for eosinophilic granulomatosis with polyangiitis: a retrospective study.

Objectives: To investigate the safety and effectiveness of mepolizumab (MPZ), an anti-interleukin-5 antibody, as remission induction therapy for severe eosinophilic granulomatosis with polyangiitis (EGPA).

Methods: The clinical courses of patients with severe EGPA over 6 months were retrospectively investigated and compared between patients treated with high-dose corticosteroid (CS) plus MPZ therapy (MPZ group, n = 7) and those treated with high-dose CS plus intravenous cyclophosphamide (IVCY) pulse therapy (IVCY group, n = 13). The primary endpoints were the MPZ retention rate and the IVCY completion rate.

Automated Design of Li -Conducting Polymer by Quantum-Inspired Annealing.

Automated molecule design by computers is an essential topic in materials informatics. Still, generating practical structures is not easy because of the difficulty in treating material stability, synthetic difficulty, mechanical properties, and other miscellaneous parameters, often leading to the generation of junk molecules. The problem is tackled by introducing supervised/unsupervised machine learning and quantum-inspired annealing.

Tranilast for advanced heart failure in patients with muscular dystrophy: a single-arm, open-label, multicenter study.

Background: The transient receptor potential cation channel subfamily V member 2 (TRPV2) is a stretch-sensitive calcium channel. TRPV2 overexpression in the sarcolemma of skeletal and cardiac myocytes causes calcium influx into the cytoplasm, which triggers myocyte degeneration. In animal models of cardiomyopathy and muscular dystrophy (MD), TRPV2 inhibition was effective against heart failure and motor function.

Synchronous gallbladder metastasis originating from residual gastric cancer: a case report and the review of literature.

Background: Gastric cancer rarely metastasizes to the gallbladder. Furthermore, there has never been a case report of simultaneous gallbladder metastasis from residual gastric cancer. Here, we report a case of synchronous gallbladder metastasis originating from a residual gastric cancer.

Factors influencing inferior vena cava diameter and its respiratory variation: Simultaneous comparison with hemodynamic data.

Background: Ultrasound assessment of inferior vena cava (IVC) diameter and its respiratory variation is widely used to estimate right atrial pressure (RAP). Generally, the IVC distends as the RAP rises; however, there may be discrepancies between the values. Therefore, it is critical to recognize clinical factors other than RAP that may influence IVC measurements.

Successful rituximab treatment in a patient with ANCA-negative granulomatosis with polyangitis: A case report.

A 68-year-old woman was referred to our hospital for further evaluation of fever, nasal congestion, deafness, and multiple pulmonary nodules refractory to antibiotic use. Despite negative findings of antineutrophil cytoplasmic antibodies, she was diagnosed with granulomatosis with polyangiitis based on the analysis of biopsy specimens of pulmonary nodules. The administrations of oral prednisolone and six intravenous cyclophosphamide (IVCY) resulted in the prompt relief of symptoms and disappearance of pulmonary nodules.
