uniLIVER: a human liver cell atlas for data-driven cellular state mapping.

The liver performs several vital functions such as metabolism, toxin removal, and glucose storage through the coordination of various cell types. With the recent breakthrough of the single-cell/single-nucleus RNA-seq (sc/snRNA-seq) techniques, there is a great opportunity to establish a reference cell map of the liver at single-cell resolution with transcriptome-wise features. In this study, we build a unified liver cell atlas uniLIVER (http://lifeome.

Non-Substituted Aromatic Pyridine N-Oxide Additives with an Intrinsic N→O Acceptor for Ultra-Long-Life Zn||MnO Batteries.

Prognostic implication of right ventricular-pulmonary artery coupling in valvular heart disease.

Valvular heart disease (VHD) leading to inadequate hemodynamic circulation is a major cause of cardiovascular morbidity and mortality worldwide. Right ventricular-pulmonary artery (RV-PA) coupling integrates the ability of RV contractility to adapt to increased pulmonary arterial afterload. If the right ventricle cannot adapt to the elevated afterload by increasing its contractile function, RV-PA uncoupling occurs.

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.

Delayed Administration of IGFBP7 Improved Bone Defect Healing via ZO-1 Dependent Vessel Stabilization.

The vascular response following injury is pivotal for successful bone-defect repair but constitutes a major hurdle in the field of regenerative medicine. Throughout this process, vessel stabilization is crucial to provide an adequate nutrient supply and facilitate efficient waste removal. Therefore, this study investigated whether promoting vascular stabilization improves bone defect repair outcomes.

Effects of the combination of Epimedium brevicornum Maxim, Ligustrum lucidum Ait and Dexamethasone on asthmatic rats by endogenous glucocorticoid pathway.

Ethnopharmacological Relevance: The theory of traditional Chinese medicine (TCM) believes that kidney deficiency is the fundamental cause of chronic refractory asthma, accompanied by pathological changes such as airway remodeling and a reduction of endogenous glucocorticoid (GC) synthesis. The combination of Epimedium brevicornum Maxim (EB) and Ligustrum lucidum Ait (LL) is frequently used in TCM for kidney tonifying and the alleviation of asthma symptoms. This approach is based on Pei-Ben formula, a renowned treatment for asthma developed by the distinguished Shanghai Practitioner, Professor Huiguang Xu, over 30 years of clinical experience.

Prognostic Value of Pre-Operative Transthoracic Echocardiography in Patients with Primary Mitral Regurgitation.

Mitral regurgitation is the second most prevalent valvular disease, with primary mitral regurgitation (PMR) accounting for 61%-67% of cases. Chronic PMR can result in progressive left ventricular remodeling and dysfunction, ultimately leading to heart failure or other adverse cardiac events. This, in turn, necessitates frequent referrals, hospitalizations, and cardiac surgeries.

Left Ventricular 3-Dimensional Global Longitudinal Strain Predicts All-Cause Mortality in Patients With Heart Transplant.

Background: The prognostic value of 3-dimensional (3D)-left ventricular global longitudinal strain (LVGLS) in recipients of heart transplant (HT) reremains unknown. This study aimed to determine whether 3D-LVGLS was the more powerful predictor of poor outcomes in recipients of HT compared with 2-dimensional (2D)-LVGLS.

Methods And Results: All consecutive adult patients who received HT and underwent at least 1 comprehensive 2D and 3D transthoracic echocardiographic examination for clinical surveillance were retrospectively enrolled.

Microbiological mechanism of hydrogen fertilizer effect in soil.

For a long time, intercropping and rotation of leguminous with non-leguminous crops is widely used to reduce the application of nitrogen fertilizer and increase yield in agroecosystems. At present, most researchers considered that this management measure is helpful for reducing fertilizer consumption and increasing its efficiency, as it can improve nutrient supply of legumestonon-legumes, the spatial nutrient utilization efficiency by enhancing soil spatial heterogeneity, and improve soil structure and disease resistance. However, current theories cannot fully explain the positive effect of crop rotation and inter-cropping systems involving legumes.

Background: Due to insufficient near-field resolution and artifacts, it is challenging to evaluate the left ventricular apical perfusion with phased-array probes. By combining high-frequency linear probe and contrast-enhanced ultrasound (CEUS), imaging of apical myocardial perfusion could be improved. The study aims to evaluate the preliminary application of CEUS by high-frequency linear probes to assess the apical perfusion.

Easy-to-Lay Poly-N Heterocyclic Additives Enable Long-Term Stabilization of Zinc-Ion Capacitor Anodes under Deep Plating/Stripping.

Addition of organic compounds containing O/N heteroatoms to aqueous electrolytes such as ZnSO (ZS) solutions is one of the effective strategies to inhibit Zn anode dendrites and side reactions. However, addressing the stability of Zn plating/stripping at high current densities and areal capacities by this method is still a challenge, especially in capacitors known for high power and long life. Herein, an organic heterocyclic compound of 1, 4, 7, 10-tetraazacyclododecane (TC) containing four symmetrically distributed N atoms is employed as ZS additive, expanding the life of Zn anodes from ≈ 30 h to 1000 and 240 h at deep plating/stripping conditions of 10 and 20 mA cm/mAh cm, respectively; the cumulative capacity is as high as 5.

Feasibility and prognostic value of tissue motion annular displacement in patients with heart transplantation.

Background: Tissue motion of mitral annular displacement (TMAD) assessment has proved to be an effective method for several cardiovascular diseases including hypertrophic cardiomyopathy, heart failure, non-ST-elevation myocardial infarction, etc. However, there are no studies exploring the feasibility of TMAD in heart transplantation (HT) recipients, and the predictive value of this parameter for adverse outcomes in these patients remains unknown. Consequently, this study aimed to evaluate the feasibility of TMAD in the evaluation of left ventricular (LV) systolic function in clinically well adult HT patients, and further investigate the prognostic value of TMAD.
