Physiological characteristics and transcriptomic analyses of alfalfa root crown in wintering.

Background: Alfalfa, scientifically identified as , is repeatedly referred to as the "king of forages". Because of its tight relationship to winter hardiness, the alfalfa's root crown plays a significant role as a storage organ over the winter. At present, it is still unknown what molecular process makes the alfalfa root crown resistant to cold.

Site-Selective Electrophilic Trifluoromethylthiolation for the Synthesis of C5- or C7-SCF-Substituted Indolines.

We report herein an efficient and site-selective electrophilic trifluoromethylthiolation of indolines. In the absence of any catalyst or additive, C5-selective trifluoromethylthiolation could proceed at room temperature. With palladium used as the catalyst, the selectivity was reversed completely, giving C7-selecive trifluoromethylthiolated products.

Extracts from Tartary Buckwheat Sprouts Restricts Oxidative Injury Induced by Hydrogen Peroxide in HepG2 by Upregulating the Redox System.

Oxidative stress, which results from an overproduction of reactive oxygen species (ROS), can cause damage that may contribute to a range of metabolic disorders. Antioxidants are considered to upregulate the activity of antioxidant enzymes, which are crucial for eliminating excess ROS and safeguarding the body against oxidative stress-induced damage. In the present study, the effect of polyphenol extracts from tartary buckwheat sprouts (TBSE) on the redox system of HepG2-cell-induced oxidative injury by hydrogen peroxide were investigated for evaluating the protective effect and mechanism of tartary buckwheat sprouts (TBS).

RRM2 Is a Putative Biomarker and Promotes Bladder Cancer Progression via PI3K/AKT/mTOR Pathway.

Thus, identifying prognostic biomarkers and understanding its underlying mechanisms are imperative to enhance patient outcomes. In this study, we aimed to investigate the prognostic significance, expression, functional activity, and underlying mechanisms of RRM2 in BLCA.

A Graph-based Goat Pangenome Reveals Structural Variations Involved in Domestication and Adaptation.

Pangenomes can facilitate a deeper understanding of genome complexity. Using de novo phased long-read assemblies of eight representative goat breeds, we constructed a graph-based pangenome of goats (Capra hircus) and discovered 113-Mb autosomal novel sequences. Combining this multi-assembly pangenome with low-coverage PacBio HiFi sequences, we constructed a long-read structural variations (SVs) database containing 59,325 SV deletions, 84,910 SV insertions, and 24,954 other complex SV alleles.

Kinase-Bench: Comprehensive Benchmarking Tools and Guidance for Achieving Selectivity in Kinase Drug Discovery.

Developing selective kinase inhibitors remains a formidable challenge in drug discovery because of the highly conserved structural information on adenosine triphosphate (ATP) binding sites across the kinase family. Tailoring docking protocols to identify promising kinase inhibitor candidates for optimization has long been a substantial obstacle to drug discovery. Therefore, we introduced "Kinase-Bench," a pioneering benchmark suite designed for an advanced virtual screen, to improve the selectivity and efficacy of kinase inhibitors.

Construction and Mechanism of Janus Nano-Graphite Reinforced Foam Gel System for Plugging Steam in Heavy Oil Reservoirs.

High-temperature steam injection is a primary method for viscosity reduction and recovery in heavy oil reservoirs. However, due to the high mobility of steam, channeling often occurs within the reservoir, leading to reduced thermal efficiency and challenges in enhancing oil production. Foam fluids, with their dual advantages of selective plugging and efficient oil displacement, are widely used in steam-injection heavy oil recovery.

Magnetic-plasmonic blackbody enhanced lateral flow immunoassay of staphylococcal enterotoxin B.

Staphylococcal enterotoxin B (SEB) in food is a serious health risk, making rapid and accurate detection methods essential. Herein, we synthesized a magnetic plasmonic blackbody, FeO@Au/PDA, by coating a gold/polydopamine (Au/PDA) layer onto an FeO core. This FeO@Au/PDA exhibits broadband absorption, excellent stability, and rapid magnetic response, making it ideal for use as a magnetic separation tool and colorimetric signal amplifier.

Probiotics alleviate chronic ethanol exposure-induced anxiety-like behavior and hippocampal neuroinflammation in male mice through gut microbiota-derived extracellular vesicles.

Background: Probiotics can colonize both the human and animal bodies and consist of active microorganisms that are beneficial to health. The use of probiotics has been shown to alleviate certain neurological diseases and disturbances in gut microbiota resulting from chronic ethanol exposure. Research indicates that probiotics can influence the nervous system via the microbial-gut-brain axis, wherein extracellular vesicles secreted by the gut microbiota play a significant role in this process.

Impact of the frequency error of direct digital synthesizers on the evaluation of two-photon light shift in atom gravimeters.

One major systematic error for free-fall atom gravimeters is the effect of two-photon light shift (LS2). In the process of evaluating LS2, the results can be affected by the residual frequency error of direct digital synthesizers due to necessary experimental parameter changes. In this paper, the impact of the coupling effect between the frequency error and LS2 has been investigated and analyzed, along with the related physical mechanisms.

Design, Synthesis, and Biological Activities Evaluation of Type I FLT3 Inhibitors for the Treatment of Acute Myeloid Leukemia.

The abnormal overexpression of FLT3 kinase is intimately associated with pathogenesis of acute myeloid leukemia (AML), positioning FLT3 inhibitors as pivotal therapeutic agents. Despite the availability of three FDA-approved FLT3 inhibitors, their clinical utility is hampered by resistance stemming from tyrosine kinase domain (TKD) mutations. Through an integrative analysis of case studies, we identified a potential advantage of type I FLT3 inhibitors in overcoming TKD mutation-induced resistance.

Gut microbiota modulates depressive-like behaviors induced by chronic ethanol exposure through short-chain fatty acids.

Background: Chronic ethanol exposure (CEE) is recognized as an important risk factor for depression, and the gut-brain axis has emerged as a key mechanism underlying chronic ethanol exposure-induced anxiety and depression-like behaviors. Short-chain fatty acids (SCFAs), which are the key metabolites generated by gut microbiota from insoluble dietary fiber, exert protective roles on the central nervous system, including the reduction of neuroinflammation. However, the link between gut microbial disturbances caused by chronic ethanol exposure, production of SCFAs, and anxiety and depression-like behaviors remains unclear.

Target-centric analysis of hepatitis B: identifying key molecules and pathways for treatment.

Hepatitis B virus (HBV) poses a significant global health challenge, potentially leading to severe liver conditions, with currently limited effective treatment options available. Xiao-Chai-Hu-Tang (XCHT), a well-known Traditional Chinese Medicine (TCM) prescription, shows promise in clinical trials for treating HBV. Therefore, screening the complex components of XCHT, identifying the active compounds, and closely exploring the targets associated with hepatitis B may constitute an effective strategy for the development of new therapeutic drugs for the treatment of this disease.

This strategy enables the rapid and facile fabrication of tubular hydrogel architectures with tunable diameters, controllable thicknesses, and excellent mechanical performance with a tensile strength of up to 1.

Co‑occurrence of clear cell renal cell carcinoma and bladder urothelial carcinoma: A case report and literature review.

The co-occurrence of clear cell renal cell carcinoma (ccRCC) and bladder urothelial carcinoma (bUC) is rare, and owing to the lack of a unified treatment plan, the prognosis is poor. The present report describes the case of a 65-year-old male patient with a history of smoking and no history of malignant tumors who presented with hematuria at the Huanghe Sanmenxia Hospital Affiliated to Henan University of Science and Technology (Sanmenxia, China) in July 2021. Urinary system computed tomography urography revealed a right renal tumor, and cystoscopy revealed intravesical lesions.
