Esophageal achalasia is a type of motility disorder characterized by incomplete relaxation of lower esophageal sphincter (LES) and absence of esophageal peristalsis. Peroral endoscopic myotomy (POEM) is a new treatment option for achalasia that is less invasive, more effective, and safe as compared to surgery. High-frequency electrotome is commonly used in POEM, but takes longer time to make the tunnel in the esophagus and causes many complications. The thulium laser decreases the risk of bleeding and perforation in endoscopy but has not been reported in digestive diseases, especially in POEM...

BACKGROUND: Left ventricular (LV) ejection fraction (EF) during high dobutamine stress (HD) by real-time gated-SPECT myocardial perfusion imaging (MPI) on a cadmium-zinc-telluride (CZT) gamma camera was validated versus cardiac magnetic resonance imaging (CMR). METHODS AND RESULTS: After injecting 99mTc-tetrofosmin (320 MBq) in 50 patients (mean age 64 +/- 11 years), EF at rest and post-stress as well as relevant changes in EF at HD (ΔEF ≥ 5%) were assessed. CZT and CMR rest EF values yielded an excellent correlation and agreement (r = 0...

Almost one in four women in Cambodia is a victim of physical, emotional or sexual violence. The study aims to provide a comprehensive understanding of the ways in which Cambodians see its causes and effects and to identify and analyse the cultural forces that underpin and shape its landscape. An ethnographic study was carried out with 102 perpetrators and survivors of emotional, physical and sexual violence against women and 228 key informants from the Buddhist and healing sectors. Their views and experiences of it were recorded-the popular idioms expressed and the symptoms of distress experienced by survivors and perpetrators...

Achalasia cardia is an esophageal motility disorder rarely reported in children and more so in young infants. Common clinical presentations include vomiting, dysphagia, regurgitation, recurrent pulmonary aspiration and failure to thrive. Diagnosis is made by barium swallow study and esophageal manometry, which is the gold standard test. Pharmocological management and endotherapy often fails and results in recurrence of symptoms. Laparoscopic Hellers myotomy, with or without anti-reflux procedure is the standard treatment of choice for children...

Bile acids (BAs) are cholesterol-derived metabolites that facilitate the intestinal absorption and transport of dietary lipids. Recently, BAs also emerged as pivotal signaling molecules controlling glucose, lipid, and energy metabolism by binding to the nuclear hormone farnesoid X receptor (FXR) and Takeda G protein receptor 5 (TGR5) in multiple organs, leading to regulation of intestinal incretin secretion, hepatic gluconeogenesis, glycogen synthesis, energy expenditure, inflammation, and gut microbiome configuration...

We report the effect of dispersion of barium titanate (BaTiO<sub>3</sub>) nanoparticles (BNPs) in a four ring bent core nematic (BCN) liquid crystal.Polarizing optical microscopy (POM) reveals the presence of a single nematic phase in pure and doped states. Polar switching has been observed in the bent core system and the value of spontaneous polarization (Ps) increases with increase in doping concentration of BNPs in BCN. Dielectric study shows a lower frequency mode, which can be ascribed to the formation of cybotactic clusters...

Histological differentiation is a major pathological criterion indicating the risk of tumor invasion and metastasis in patients with hepatocellular carcinoma. The degree of tumor differentiation is controlled by a complex interacting network of associated proteins. The principal aim of the present study is to identify the possible differentiation-related proteins which may be used for early diagnosis and more effective therapies. We compared poorly differentiated and well-differentiated hepatocellular carcinoma tissues by using 2-dimensional gel electrophoresis and matrix-assisted laser desorption ionization time-of-flight mass spectrometry...

BACKGROUND: In Germany reimbursement for new medical technologies is often enforced before a social court. It is likely that these judicial decisions also affect the sickness funds' decisions on requests for reimbursement and thus patient access to new technologies in general. OBJECTIVES: The aim of this study was to identify the technologies that have repeatedly generated court actions and whether these actions have been successful. The focus was on differences between sectors, technology groups and indications...

We report dielectric microsphere array-based optical super-resolution microscopy. A dielectric microsphere that is placed on a sample is known to generate a virtual image with resolution better than the optical diffraction limit. However, a limitation of such type of super-resolution microscopy is the restricted field-of-view, essentially limited to the central area of the microsphere-generated image. We overcame this limitation by scanning a micro-fabricated array of ordered microspheres over the sample using a customized algorithm that moved step-by-step a motorized stage, meanwhile the microscope-mounted camera was taking pictures at every step...

Emerging evidence indicates that loss of inhibitory tone in amygdala with its subsequent overactivation contributes to the development of multiple mental disorders such as anxiety disorders and post-traumatic stress disorder (PTSD). Harmine is a member of natural β-carboline alkaloids which can readily cross the blood brain barrier and displays significant antidepressant and anxiolytic effects in rodents. However, the underlying neurobiological mechanisms are largely unknown. Here, by using whole-cell patch clamp recordings in in vitro amygdala slices, we examined the effect of harmine on glutamatergic and GABAergic transmission onto basal amygdala (BA) projection neurons (PNs)...

Barium zirconate titanate (Ba(ZrxTi1-x)O3-BZT) ceramics with Zr4+ content x of 5, 10, 15, 20, 25 and 30 mol%, were prepared using a solid-state-reaction approach. The microstructures, morphologies, and electric properties were characterized using XRD, SEM and impedance analysis methods, respectively. The dielectric analyses indicate that the BZT bulk ceramics show characteristics of phase transition from a normal ferroelectric to a relaxor ferroelectric with the increasing Zr4+ ionic content. The electrocaloric effect (ECE) adiabatic temperature change decreases with the increasing Zr4+ content...

Increasing evidence indicated that inflammatory biomarkers, including neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and prognostic nutritional index (PNI), can be used as prognostic indicators in esophageal squamous cell carcinoma (ESCC). However, which is the best predictor for prognosis in ESCC remain controversial. Few studies focused on the association between inflammatory biomarkers and postoperative chemotherapy. A cohort of 515 non-metastatic ESCC patients was reviewed retrospectively...
