Background and aim:  Strictures are a major complication of esophageal endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma. Post ESD, stricture develops during the process of scar formation, which is related to inflammation caused by ESD. We planned a study to evaluate whether certain electrosurgical unit modes could attenuate strictures after esophageal ESD. Methods:  A total of 16 ESD, three-quarters of the esophageal circumference, were performed in four live pigs...

PURPOSE: To explore the heterogeneous transmission dynamics for influenza and identify the optimal serum antibody titer cutoff values for estimating its cumulative incidence. METHODS: We constructed a mathematical model describing serologically dependent disease transmission. The diagnostic performances of two serum antibody titer tests (single serum test and paired sera test) were evaluated, and cumulative disease incidence estimators were formulated. The model simulated the 2009 Japanese influenza A/H1N1 epidemic and investigated the optimal cutoff values and cumulative incidence estimates for this epidemic...

Dancing on pointe and relevé requires extreme plantar flexion of the talo-crural joint. Hence, these positions may lead to posterior ankle impingement syndrome (PAIS). PAIS often coincides with flexor hallucis longus tendinopathy (FHL tendinopathy, or "dancers' tendinitis"). Both injuries can appear in isolation as well. The goal of this review is to evaluate the results and the available levels of evidence of conservative and operative treatment (both open and endoscopic) of PAIS and FHL tendinopathy in dancers...

BACKGROUND: Patients with transmural myocardial infarction (MI) who undergo endocardial-only substrate ablation are at an increased risk of ventricular tachycardia (VT) recurrence. Late gadolinium-enhanced cardiac magnetic resonance (LGE-CMR) could be used to assess infarct transmurality (IT). However, the degree of IT associated to epicardial arrhythmogenic substrate (AS) has not been determined. OBJECTIVE: To determine the degree of IT observed in LGE-CMR and multi-detector computed tomography (MDCT) that predicts the presence of epicardial AS...

Diaphragm paralysis can cause significant shortness of breath. This condition can be treated with diaphragm plication. We illustrate two cases where we used a knotless suture and total portal thoracoscopic technique to successfully plicate the diaphragm. A 70-year-old female with right-sided and a 44-year-old male with left-sided diaphragm paralysis. Both patients had a sniff test that showed paradoxical movement of the diaphragm. The port placements during the procedure were different due to the laterality but both patients had three 5-mm ports and one 12-mm port for the procedure...

We report the development of solution-processed reduced phosphomolybdic acid (rPMA) containing molybdenum oxide units for post-treatment-free hole-injection layers (HILs) in organic light-emitting devices (OLEDs). The physical and chemical properties of rPMA, including its structure, solubility in several solvents, film surface roughness, work function, and valence states, were investigated. The formation of gap states just below the Fermi level of rPMA was observed. Without any post-treatment after the formation of rPMA films, OLEDs employing rPMA as an HIL exhibited a very low driving voltage and a high luminous efficiency...

Endoscopic sphincterotomy (ES) is a standard procedure for bile duct stone removal. However, the safety of ES in patients with hemophilia remains unknown. We treated a 46-year-old man who had choledocholithiasis and severe hemophilia A with high-responding inhibitors during immune tolerance induction therapy. Since coagulation factor VIII inhibitors neutralize and inactivate endogenous and exogenous factor VIII, bleeding risk is higher in hemophilia A patients with inhibitors than in those without inhibitors...

Increasing evidence has pointed to that dysregulation of the endo-lysosomal system is an early cellular phenotype of pathogenesis for Alzheimer's disease (AD). Rab5, a small GTPase, plays a critical role in mediating these processes. Abnormal overactivation of Rab5 has been observed in post-mortem brain samples of Alzheimer's patients as well as brain samples of mouse models of AD. Recent genome-wide association studies of Alzheimer's disease have identified RIN3 (Ras and Rab Interactor 3) as a novel risk factor for the disease...

BACKGROUND AND STUDY AIM: Stricture is a major complication of esophageal endoscopic submucosal dissection (ESD) for superficial esophageal carcinoma. To date, various methods have been developed to prevent stricture. However, the mechanism by which different electrosurgical unit (ESU) modes affect the formation of post-ESD stricture has not been evaluated. This study aimed to compare the degree of stricture caused by two major ESU modes (ENDO CUT mode and FORCED COAG mode) in a porcine model...

A 47-year-old Japanese man was referred to hospital after the detection of a liver tumor. Dynamic computed tomography and Gd-EOB-DTPA-enhanced magnetic resonance imaging were consistent with a diagnosis of hepatocellular carcinoma (HCC). No perfusion defect was observed in the post-vascular phase of contrast-enhanced ultrasound (CEUS). Histopathological staining of the tumor cells was positive for antibodies against HMB-45 and CD68, confirming the diagnosis of hepatic angiomyolipoma (HAML). These findings indicated the presence of macrophages in HAML...
