Efficient parameter estimation of the lognormal-Rician turbulence model based on the -nearest neighbor and data generation method.

In this paper, we propose a novel, to the best of our knowledge, and efficient parameter estimator based on the -nearest neighbor (NN) and data generation method for the lognormal-Rician turbulence channel, which is of vital importance to the free-space optical/quantum communications. The Kolmogorov-Smirnov (KS) goodness-of-fit statistical tools are employed to investigate the validity of the NN approximation under different channel conditions, and it is shown that the choice of plays a significant role in the approximation accuracy. We present several numerical results to illustrate that solving the constructed objective function can provide a reasonable estimate of the actual values.

Mg-B-O Coated P2-Type Hexagonal NaMnNiO as a High-Performance Cathode for Sodium-Ion Batteries.

P2-type NaMnNiO as the cathode for sodium-ion batteries, has a relatively high theoretical specific capacity, but its unstable crystal structure and undesirable phase transitions lead to rapid capacity decay. In this work, Mg-B-O coated NaMnNiO microspheres have been synthesized via a liquid-phase method based on solvothermal synthesized NaMnNiO. The Mg-B-O coating layer significantly improves the electrochemical performance, including specific capacity, rate capability, and cycle stability.

Profiling Exosomal Metabolomics as a Means for Diagnosis and Researching Early-Stage Hypertensive Nephropathy.

Hypertension (HT) is a prevalent medical condition showing an increasing incidence rate in various populations over recent years. Long-term hypertension increases the risk of the occurrence of hypertensive nephropathy (HTN), which is also a health-threatening disorder. Given that very little is known about the pathogenesis of HTN, this study was designed to identify disease biomarkers, which enable early diagnosis of the disease, through the utilization of high-throughput untargeted metabolomics strategies.

Baicalin is one of the major active ingredients of a traditional Chinese herbal medicine, Huang Qin, which is used to treat patients with chest pain or cardiac discomfort. However, the underlying mechanism(s) of the cardioprotective effect of baicalin are still not fully understood.

A Simple and Sensitive RT-qPCR Technology for Rapid Detection of Porcine Reproductive and Respiratory Syndrome Virus.

To establish a rapid and sensitive detection method for the porcine reproductive and respiratory syndrome virus (PRRSV), gene-specific primers and a TaqMan probe were designed based on the gene of PRRSV, and a new stable fully pre-mixed reverse transcription real-time fluorescence quantitative PCR (RT-qPCR) reaction mixture was developed. A simple and rapid RT-qPCR detection method for PRRSV was developed by optimizing nucleic acid amplification conditions. The results showed that the method was able to specifically detect PRRSV without cross-reactivity with the other 11 porcine susceptible viruses.

Diminazene aceturate, an ACE2 activator, ameliorates testicular injury in diet-induced obese mice.

In Brief: Obesity is a prevalent health concern globally, often associated with testicular damage that can lead to male infertility. This study investigates the improvement of obesity-induced testicular damage by ACE2 agonist diminazene aceturate (DIZE) and explores the role of the ACE2/Ang 1-7/MasR axis in this process.

Abstract: DIZE improved obesity and metabolic disturbances in diet-induced obesity (DIO) mice.

AlphaFold and Docking Approaches for Antibody-Antigen and Other Targets: Insights From CAPRI Rounds 47-55.

Accurate modeling of the structures of protein-protein complexes and other biomolecular interactions represents a longstanding and important challenge for computational biology. The Critical Assessment of PRedicted Interactions (CAPRI) experiment has served for over two decades as a key means to assess and compare current approaches and methods through blind predictive scenarios, highlighting useful strategies, and new developments. Here we describe the performance of our laboratory's team in recent CAPRI rounds, which included submissions for 10 modeling targets.

Transcutaneous electrical acupoint stimulation for upper limb spasticity after stroke: effect and feasibility-a randomised pilot study.

Importance: Limb spasticity is a common issue among stroke patients. Transcutaneous electrical acupoint stimulation (TEAS) is recommended as an alternative therapy for managing upper limb spasticity after stroke; however, its potential effects and feasibility remain uncertain.

Objective: To investigate the potential effects and feasibility of TEAS on motor function in patients with upper limb spasticity after stroke.

SPI1 facilitates microfracture-mediated cartilage regeneration in the elderly by enhancing bone marrow stromal cells ctemness.

Bone marrow stimulation treatment by bone marrow stromal cells (BMSCs) released from the bone medullary cavity and differentiated into cartilage via microfracture surgery is a frequently employed technique for treating articular cartilage injuries, yet the treatment presents a main drawback of poor cartilage regeneration in the elderly. Prior research indicated that aging could decrease the stemness capacity of BMSCs, thus we made a hypothesis that increasing old BMSCs (OBMSCs) stemness might improve the results of microfracture in the elderly. First, we investigated the correlation between microfracture outcomes and BMSCs stemness using clinical data and animal experiments.
