Shenling Baizhu San improves spermatogenic dysfunction in hyperuricemia mice by regulating Sirt3/Nrf2 to inhibit testicular ferroptosis.

Ethnopharmacological Relevance: The effect of hyperuricemia (HUA) on testicular spermatogenesis cannot be ignored. The classical Chinese medicine compound Shenling Baizhu San (SLBZS) can reduce uric acid and improve testicular spermatogenesis, while researchers have not well explored the related pathology and pharmacodynamic mechanism have.

Aims Of Study: To investigate whether the dysfunction of testicular spermatogenesis caused by HUA and the therapeutic effect of SLBZS are related to testicular cell ferroptosis.

Wutou Decoction: A latest review on molecular mechanisms, clinical studies, quality control, pharmacokinetic studies, pharmacological effects, toxicity, and target prediction.

Ethnopharmacological Relevance: Traditional Chinese Medicine (TCM) has great potential and advantages in the treatment of rheumatoid arthritis (RA). Wutou decoction (WTD) was first recorded as a pill in the TCM classical book Synopsis of Prescriptions of the Golden Chamber written by Zhang Zhongjing in the Eastern Han Dynasty (25-220 CE). It has significant therapeutic effects in delaying and reversing RA while improving patients' clinical symptoms, making it the best example of TCM treatment for RA.

The resistance mechanism of B_P225F and B_H272R mutations in succinate dehydrogenase in Botrytis cinerea.

Botrytis cinerea populations resistant to succinate dehydrogenase inhibitors (SDHIs) represent a major problem for the sustainable development of modern agriculture. In the present study, the resistance mechanism of B_P225F and B_H272R mutations in B. cinerea SDH (BcSDH) resistant to SDHIs fungicides, including boscalid (BOS), penflufen (PEN), pydiflumetofen (PYD), fluopyram (FLU), and benzovindiflupyr (BEN), was uncovered.

Effects of neuropeptide F signaling on feeding, growth and development of Plutella xylostella (L.) larvae.

The neuropeptide F (NPF) signaling, comprising NPF and neuropeptide F receptor (NPFR), role in regulating insect behaviors and physiological processes. We cloned the genes encoding NPF and NPFR from Plutella xylostella, a notorious pest of cruciferous crops. Notably, the NPF gene produced two splicing variants, Px-NPF1 and Px-NPF2, with distinct expression patterns.

A 3D bioprinted potential colorectal tumor model based on decellularized matrix/gelatin methacryloyl/nanoclay/sodium alginate hydrogel.

Colorectal cancer (CRC) is now the third most common cancer worldwide. However, the development cycle for anticancer drugs is lengthy and the failure rate is high, highlighting the urgent need for new tumor models for CRC-related research. The decellular matrix (dECM) offers numerous cell adhesion sites, proteoglycan and cytokines.

CD36-mediated uptake of oxidized LDL induces double-negative regulatory T cell ferroptosis in metabolic dysfunction-associated steatotic liver disease.

Background: Metabolic alterations have been shown to instigate liver inflammation in metabolic dysfunction-associated steatotic liver disease (MASLD), but the underlying mechanism is not fully elucidated. During MASLD progression, intrahepatic CD3TCRαβCD4CD8 double negative T regulatory cells (DNT) decrease cell survival and immunosuppressive function, leading to aggravated liver inflammation. In this study, we aim to reveal the underlying mechanisms that cause changes in DNT during MASLD progression.

Coupling effect of cyanobacterial blooms with migration and transformation of typical pollutants in lake or reservoir: Enhanced or decreased?

Eutrophication of lake and reservoir caused by cyanobacterial harmful algal blooms (cyanoHABs) become a global ecological problem because of massive destruction of ecosystems, which have attracted attentions widely. In addition to the production of cyanotoxins by certain bloom-forming species, there may also be direct or indirect interactions between cyanobacteria blooms and various pollutants in lakes or reservoirs. Based on bibliometrics, 19110 papers in Web of Science (WOS) and 2998 papers in the China National Knowledge Infrastructure (CNKI) on eutrophication and cyanobacterial blooms in lakes and reservoirs were analyzed, which showed that research on this topic has been ongoing for nearly 80 years with a gradual increase in its popularity.

Machine learning and clinician predictions of antibiotic resistance in Enterobacterales bloodstream infections.

Background: Patients with Gram-negative bloodstream infections are at risk of serious adverse outcomes without active treatment, but identifying who has antimicrobial resistance (AMR) to target empirical treatment is challenging.

Methods: We used XGBoost machine learning models to predict antimicrobial resistance to seven antibiotics in patients with Enterobacterales bloodstream infection. Models were trained using hospital and community data from Oxfordshire, UK, for patients with positive blood cultures between 01-January-2017 and 31-December-2021.

Exploring the cellular and molecular basis of nerve growth factor in cerebral ischemia recovery.

Vascular obstruction often causes inadequate oxygen and nutrient supply to the brain. This deficiency results in cerebral ischemic injury, which significantly impairs neurological function. This review aimed to explore the neuroprotective and regenerative effects of nerve growth factor (NGF) in cerebral ischemic injury.

Ultrasonic detection of wrinkles in composites with gradual phase shift migration.

Fiber reinforced polymer composites (FRPs) are essential for various industrial fields, but wrinkles inside will greatly reduce their mechanical properties. Full-matrix capture (FMC) is a popular data structure for ultrasonic phased array imaging in composites. However, such structure may lead to data redundancy and noise interference.

MrSeNet: Electrocardiogram signal denoising based on multi-resolution residual attention network.

Electrocardiography (ECG) is a widely used, non-invasive, and cost-effective diagnostic method that plays a crucial role in the early detection and management of cardiac conditions. However, the ECG signal is easily disrupted by various noise signals in the real world, leading to a decrease in signal quality and potentially compromising accurate clinical interpretation. With the goal of reducing noise in ECG signals, this research proposes an end-to-end multi-resolution deep learning network with attention mechanism, namely the MrSeNet to perform effective denoising of ECG data.

The human zinc-binding cysteine proteome.

Zinc is an essential micronutrient that regulates a wide range of physiological processes, most often through zinc binding to protein cysteine residues. Despite being critical for modulation of protein function, the cysteine sites in the majority of the human proteome that are subject to zinc binding remain undefined. Here, we develop ZnCPT, a deep and quantitative mapping of the zinc-binding cysteine proteome.

Controlled growth of silver on gold triangular nanoprisms: Improved surface enhanced Raman scattering for ultrasensitive detection of cancer biomarker.

The precise design and synthesis of Au and Ag composite nanomaterials can provide them with richer plasmonic modes, resulting in enhanced optical properties. Here, a novel strategy was demonstrated to control the selective deposition of Ag at different positions of Au triangular nanoprisms (Au TNPs). 1,4-benzenedithiol (BDT) was selectively absorbed in different positions of Au TNPs which made Ag selectively deposited on Au TNPs.

Changes in sleep duration status and risk of high carotid intima-media thickness in children: A prospective cohort study.

Background: Short sleep duration is common in the pediatric population and is associated with an increased risk of high carotid intima-media thickness (cIMT), a marker of subclinical atherosclerosis. However, little is known regarding whether changes in sleep duration status over time can alter the risk of high cIMT in children.

Objectives: To examine the association between changes in sleep duration status and high cIMT in a cohort study of Chinese children.

Accuracy of interleukin-27 in diagnosing tuberculous pleural effusion: Age should be considered.

Background: Tuberculous pleural effusion (TPE) diagnosis still faces many difficulties and challenges. Some studies have shown that pleural interleukin -27 (IL-27) had a diagnostic potential for TPE. However, their findings are not always consistent.

Compartmentalized localization of perinuclear proteins within germ granules in C. elegans.

Germ granules, or nuage, are RNA-rich condensates that are often docked on the cytoplasmic surface of germline nuclei. C. elegans perinuclear germ granules are composed of multiple subcompartments, including P granules, Mutator foci, Z granules, SIMR foci, P -bodies, and E granules.
