Enhanced brain network flexibility by physical exercise in female methamphetamine users.

Unlabelled: Methamphetamine (MA) abuse is increasing worldwide, and evidence indicates that MA causes degraded cognitive functions such as executive function, attention, and flexibility. Recent studies have shown that regular physical exercise can ameliorate the disturbed functions. However, the potential functional network alterations resulting from physical exercise have not been extensively studied in female MA users.

Synthesis and clinical application of new drugs approved by NMPA in 2023.

The National Medical Products Administration (NMPA) in China plays a crucial role in regulating drug approval and ensuring the safety and efficacy of pharmaceutical products. In 2023, the NMPA authorized the approval of 82 novel therapeutic agents, including 48 chemical drugs, 22 biological drugs, 4 vaccines, and 8 traditional Chinese medicines. These approvals span a broad spectrum of therapeutic areas, with a strong focus on oncology, central nervous system disorders, anti-infective treatments, hematology, cardiovascular diseases, ophthalmology, and immunomodulation.

A potential role for the interaction of Wolbachia surface proteins with the Drosophila microtubulin in maintenance of endosymbiosis and affecting spermiogenesis.

Wolbachia, as a widely infected intracellular symbiotic bacterium in Arthropoda, is able to manipulate the reproduction of insect hosts for facilitating their own transmission. Cytoplasmic incompatibility (CI) is the most common phenotype that Wolbachia induced in insect hosts where they resulted in the failure of uninfected egg hatch when fertilized with the sperm derived from Wolbachia-infected males, suggesting that the sperm are modified by Wolbachia during spermatogenesis. Although the molecular mechanisms of CI are beginning to be understood, the effects of Wolbachia on the symbiotic relationship and the proper dynamics of spermatogenesis have not yet been fully investigated.

A Natural Eumelanin-Assisted Pullulan/Chitosan Hydrogel for the Management of Diabetic Oral Ulcers.

Existing methods for treating diabetic oral ulcers often fall short in clinical environments due to potential bacterial contamination, oxidative harm, and hindered angiogenesis throughout the healing process. Here, a hydrogel patch (HYG2) have been developed for local in situ application. HYG2 comprises oxidized pullulan, quaternized chitosan, and eumelanin nanoparticles derived from cuttlefish ink.

Impact of easing COVID-19 restrictions on antibiotic usage in Eastern China using wastewater-based epidemiology.

Coronavirus Disease 2019 (COVID-19) emerged in December 2019, prompting the implementation of a "zero-COVID" policy in Mainland China. The easing of this policy in December 2022 led to a surge in COVID cases, which was believed to significantly increase antibiotic usage, potentially due to antibiotic misuse or increased coinfections. Our study aimed to compare antibiotic consumption and patterns before and after this policy adjustment.

Pyrolysis-Free Synthesis of Synergistic Single-Atom/Nanocluster Electrocatalysts for Hydrogen Evolution.

Constructing catalysts that simultaneously contain single atom/metal nanocluster active sites is a promising strategy to enhance the original catalytic behavior and accelerate the catalysis involving multi-electron reactions or multi-intermediates. Herein, the pyrolysis-free synthetic method is developed to integrate single atoms and nanoclusters towards highly satisfactory catalytic performances for both acidic and alkaline hydrogen electrocatalysis. The controllable pyrolysis-free strategy allows the precise modulation of the active centers, realizing the optimization of the adsorption energy and the regulation of the synergistic active components.

SlVQ15 recruits SlWRKY30IIc to link with jasmonate pathway in regulating tomato defence against root-knot nematodes.

Tomato is one of the most economically important vegetable crops in the world and has been seriously affected by the devastating agricultural pest root-knot nematodes (RKNs). Current understanding of tomato resistance to RKNs is quite limited. VQ motif-containing family proteins are plant-specific regulators; however, whether and how tomato VQs regulate resistance to RKNs is unknown.

Observation of Discrete Charge States of a Coherent Two-Level System in a Superconducting Qubit.

We report observations of discrete charge states of a coherent two-level system (TLS) that is strongly coupled to an offset-charge-sensitive superconducting transmon qubit. We measure an offset charge of 0.072e associated with the two TLS eigenstates, which have a transition frequency of 2.

Methodology comparison of environmental sediment fungal community analysis.

Fungi play important roles in ecosystems. Analyzing fungal communities in environments has long been a challenge due to the large difference in compositions retrieved using different methods or sequencing regions, obscuring the true abundance and species information. Our study aimed to compare and determine more accurate approach for evaluating fungal populations in river sediment.

EGFR-mediated HSP70 phosphorylation facilitates PCNA association with chromatin and DNA replication.

Efficient DNA replication requires highly coordinated programs for the timely recruitment of protein complexes to DNA replication forks. Defects in this process result in replication stress, which in turn activates cell cycle checkpoints, suppresses cell proliferation and induces apoptosis. In response to persistent cell growth signals that speed up DNA replication processes, cells accelerate the recruitment of DNA replication proteins to avoid DNA replication stress.

Accessibility evaluation and multi-scenario optimization of medical services in underdeveloped city driven by multi-source data and latest policies for China.

Equitable and high-quality medical services are more urgent in underdeveloped cities for the higher population ageing and demanding social justice. However, there is little attention paid to the multi-level medical services, particularly regarding the time indicators under the latest policies for underdeveloped cities. The improved efforts were hampered partly by single scenario of location optimization, ignoring the integrated optimization for both road infrastructure and institution location.

A Cardiac-Targeting and Anchoring Bimetallic Cluster Nanozyme Alleviates Chemotherapy-Induced Cardiac Ferroptosis and PANoptosis.

Doxorubicin (DOX), a potent antineoplastic agent, is commonly associated with cardiotoxicity, necessitating the development of strategies to reduce its adverse effects on cardiac function. Previous research has demonstrated a strong correlation between DOX-induced cardiotoxicity and the activation of oxidative stress pathways. This work introduces a novel antioxidant therapeutic approach, utilizing libraries of tannic acid and N-acetyl-L-cysteine-protected bimetallic cluster nanozymes.

Decoding PTEN: from biological functions to signaling pathways in tumors.

The tumor suppressor gene Phosphatase and tensin homologue deleted on chromosome 10 (PTEN), possessing both protein and lipid phosphatase activities, is frequently mutated in various human cancers. PTEN aberrations disrupt critical cellular processes like proliferation, apoptosis, migration, and invasion, thereby promoting tumor growth. In the cells, PTEN localizes to the nucleus, cytoplasm, or cell membrane, and its roles depends on the subcellular localization.
