Prognostic Value of LV Global Longitudinal Strain by 2D and 3D Speckle-Tracking Echocardiography in Patients With HFpEF.

Background: In patients with heart failure with preserved ejection fraction (HFpEF), the impact of type 2 diabetes (T2D) on left ventricular global longitudinal strain (LV GLS) and its prognostic implications remains unclear. We aimed to evaluate LV function using two-dimensional (2D) and three-dimensional (3D) speckle-tracking echocardiography in patients with HFpEF with and without T2D, and to investigate its prognostic significance.

Methods: A total of 335 patients with HFpEF were prospectively enrolled for echocardiographic evaluation.

CD70-targeted iPSC-derived CAR-NK cells display potent function against tumors and alloreactive T cells.

Clinical application of autologous chimeric antigen receptor (CAR)-T cells is complicated by limited targeting of cancer types, as well as the time-consuming and costly manufacturing process. We develop CD70-targeted, induced pluripotent stem cell-derived CAR-natural killer (NK) (70CAR-iNK) cells as an approach for universal immune cell therapy. Besides the CD70-targeted CAR molecule, 70CAR-iNK cells are modified with CD70 gene knockout, a high-affinity non-cleavable CD16 (hnCD16), and an interleukin (IL)-15 receptor α/IL-15 fusion protein (IL15RF).

Prussian Blue Analogues "Dressed" in MXene Nanosheets Tightly for High Performance Lithium-Ion Batteries.

MXenes, have been considered as a new generation anode material in lithium-ion batteries for lower lithium-ion diffusion barriers and superior conductivity. Unfortunately, their structures are prone to aggregation and stacking, hindering further shuttle of lithium ions and electrons, resulting in lower discharge capacity. Therefore, the introduction of interlayer spacers for the preparation of MXene-based hybrids has attracted much attention.

915 nm pumping kilowatt fiber oscillator with high optical-to-optical efficiency.

We demonstrate an all-fiber oscillator with high optical-to-optical efficiency using laser diodes working at 915nm as the pump sources to reduce the demand for thermal management. When the output power of the bidirectional pumped oscillator is 1.16kW, the optical-to-optical efficiency is as high as 75.

Secondary metal ion-induced electrochemical reduction of U(VI) to U(IV) solids.

Recent studies have shown that aqueous U(VI) ions can be transformed into U(VI) precipitates through electrocatalytic redox reactions for uranium recovery. However, there have been no reports of U(IV) solids, such as UO, using electrochemical methods under ambient conditions since low-valence states of uranium are typically oxidized to U(VI) by O or HO. Here we developed a secondary metal ion-induced strategy for electrocatalytic production of U(IV) solids from U(VI) solutions using a catalyst consisting of atomically dispersed gallium on hollow nitrogen-doped carbon capsules (Ga-N-C).

P2Y receptor inhibitors are commonly used in clinical antiplatelet therapy, typically alongside other medications. Vicagrel, a promising P2Y receptor inhibitor, has submitted a new drug marketing application to the United States Food and Drug Administration. Its primary metabolites and some metabolic pathways are identical to those of clopidogrel.

The Art of Finding the Right Drug Target: Emerging Methods and Strategies.

Drug targets are specific molecules in biological tissues and body fluids that interact with drugs. Drug target discovery is a key component of drug discovery and is essential for the development of new drugs in areas such as cancer therapy and precision medicine. Traditional in vitro or in vivo target discovery methods are time-consuming and labor-intensive, limiting the pace of drug discovery.

Coupled-Channel Analysis of the χ_{c1}(3872) Line Shape with BESIII Data.

We perform a study of the χ_{c1}(3872) line shape using the data samples of e^{+}e^{-}→γχ_{c1}(3872), χ_{c1}(3872)→D^{0}D[over ¯]^{0}π^{0}, and π^{+}π^{-}J/ψ collected with the BESIII detector. The effects of the coupled channels and the off-shell D^{*0} are included in the parametrization of the line shape. The line shape mass parameter is obtained to be M_{X}=(3871.

KLF15-Cyp3a11 Axis Regulates Rifampicin-Induced Liver Injury.

Rifampicin (RFP) has demonstrated potent antibacterial effects in the treatment of pulmonary tuberculosis. However, the serious adverse effects on the liver intensively limit the clinical usage of the drug. Deacetylation greatly reduces the toxicity of RFP but also retains its curative activity.

Protein Kinase A Is a Master Regulator of Physiological and Pathological Cardiac Hypertrophy.

Background: The sympathoadrenergic system and its major effector PKA (protein kinase A) are activated to maintain cardiac output coping with physiological or pathological stressors. If and how PKA plays a role in physiological cardiac hypertrophy (PhCH) and pathological CH (PaCH) are not clear.

Methods: Transgenic mouse models expressing the PKA inhibition domain (PKAi) of PKA inhibition peptide alpha (PKIalpha)-green fluorescence protein (GFP) fusion protein (PKAi-GFP) in a cardiac-specific and inducible manner (cPKAi) were used to determine the roles of PKA in physiological CH during postnatal growth or induced by swimming, and in PaCH induced by transaortic constriction (TAC) or augmented Ca influx.

Setting 6-Minute Minimal Examination Time Improves the Detection of Focal Upper Gastrointestinal Tract Lesions During Endoscopy: A Multicenter Prospective Study.

Introduction: Positive correlation between examination time and neoplasm detection using esophagogastroduodenoscopy (EGD) has been described by observational studies, but the effect of setting minimal examination time still requires investigation.

Methods: This prospective, 2-stage, interventional study was conducted in 7 tertiary hospitals in China, enrolling consecutive patients undergoing intravenously sedated diagnostic EGDs. In stage I, the baseline examination time was collected without informing the endoscopists.

Systolic Blood Pressure Control Targets to Prevent Major Cardiovascular Events and Death in Patients With Type 2 Diabetes: A Systematic Review and Network Meta-Analysis.

Background: Previous meta-analyses using traditional pairwise comparisons did not support intensive systolic blood pressure (SBP) control in patients with diabetes and included trials published before 2015. We aimed to identify the optimal SBP control targets in patients with type 2 diabetes using a systematic review and network meta-analysis of accumulating evidence.

Methods: We systematically searched PubMed, Embase, and Cochrane Library from inception to August 29, 2022 for randomized controlled trials comparing different blood pressure targets, antihypertensive agents against placebo, or dual antihypertensive agents against single agent in patients with type 2 diabetes.
