To investigate potential alterations in gut microbiota and metabolites in newly diagnosed and untreated MG patients, we conducted a case-control study.

A method for generating synthetic longitudinal health data.

Getting access to administrative health data for research purposes is a difficult and time-consuming process due to increasingly demanding privacy regulations. An alternative method for sharing administrative health data would be to share synthetic datasets where the records do not correspond to real individuals, but the patterns and relationships seen in the data are reproduced. This paper assesses the feasibility of generating synthetic administrative health data using a recurrent deep learning model.

Study of electrical conductivity response upon formation of ice and gas hydrates from salt solutions by a second generation high pressure electrical conductivity probe.

We recently reported the development of a high pressure electrical conductivity probe (HP-ECP) for experimental studies of formation of gas hydrates from electrolytes. The onset of the formation of methane-propane mixed gas hydrate from salt solutions was marked by a temporary upward spike in the electrical conductivity. To further understand hydrate formation a second generation of window-less HP-ECP (MkII), which has a much smaller heat capacity than the earlier version and allows access to faster cooling rates, has been constructed.

Interferon alpha on expression of hTERT mRNA in peripheral blood mononuclear cells of patients with chronic hepatitis B.

Cell division is closely related to telomerase activity (hTERT mRNA). Lower expression of lymphocitic hTERT mRNA may easily cause cell aging, which is not beneficial to maintaining a durable lymphocyte division. To date, there is no study to investigate IFNα therapy on hTERT mRNA expression in PBMCs of patients with chronic hepatitis B (CHB).

Hyperthyroidism-induced left ventricular diastolic dysfunction: implication in hyperthyroidism-related heart failure.

Background: Heart failure occurs in 6% of hyperthyroid patients. Nonetheless, only half of those with hyperthyroidism-related heart failure have impaired left ventricular (LV) systolic function. Thus, diastolic dysfunction may play an important role in the pathogenesis.

Left ventricular apical akinetic aneurysmatic area associated with permanent right ventricular apical pacing for advanced atrioventricular block: clinical characteristics and long-term outcome.

Background: Right ventricular apical (RVA) pacing can induce left ventricular (LV) dyssynchrony and dysfunction. In this article, we describe the prevalence, clinical characteristics, and outcome in a subset of patients with unrecognized LV apical akinetic aneurysmatic area associated with permanent RVA pacing as potential causes of heart failure (HF) and/or ventricular tachyarrhythmias (VT).

Methods And Results: We retrospectively studied 220 patients with permanent RVA pacing and no pre-existing structural heart disease in our follow-up clinic for high-degree atrioventricular block.

Interatrial mechanical dyssynchrony worsened atrial mechanical function in sinus node disease with or without paroxysmal atrial fibrillation.

Introduction: Atrial electromechanical dysfunction might contribute to the development of atrial fibrillation (AF) in patients with sinus node disease (SND). The aim of this study was to investigate the prevalence and impact of atrial mechanical dyssynchrony on atrial function in SND patients with or without paroxysmal AF.

Methods: We performed echocardiographic examination with tissue Doppler imaging in 30 SND patients with (n = 11) or without (n = 19) paroxysmal AF who received dual-chamber pacemakers.

Upgrading pacemaker patients with right ventricular apical pacing to right ventricular septal pacing improves left ventricular performance and functional capacity.

Background: Right ventricular (RV) apical pacing results in abnormal left ventricular (LV) electrical and mechanical activation and is associated with an increased risk of developing heart failure. Chronic RV septal pacing has been shown to be superior to RV apical pacing in newly implanted patients. However, whether RV septal pacing can reverse deleterious effects of RV apical pacing remain unclear.

Quartz crystal microbalance study of the interfacial nanobubbles.

The applications of quartz crystal microbalance (QCM) to the study of surface and interfacial science such as adsorption have become progressively common and popular these days. In this work, QCM with dissipation monitoring was used to study the formation of nanobubbles on bare and thiol-coated gold surfaces. The nanobubbles were produced using one of the established solvent exchange protocols and the formation was first confirmed by the tapping mode atomic force microscopy (AFM).

Thermodynamic stability of interfacial gaseous states.

We studied the thermodynamic stability of interfacial gaseous states on atomically smooth highly ordered pyrolytic graphite (HOPG) in water using atomic force microscopy. Quasi-two-dimensional gas layers (micropancakes) required a higher supersaturation of gas than spherical-cap-shaped nanobubbles. The two forms of gas coexisted at a sufficiently high supersaturation of gas where one or more of the nanobubbles may sit on top of a micropancake.
