Insect Cytochrome P450 Database: An Integrated Resource of Genetic Diversity, Evolution and Function.

Insects, the most numerous and diverse group of animal species on Earth, have important interactions with humans through providing resources, transmitting diseases and damaging agricultural cultivars. Cytochrome P450 monooxygenases (P450s) are one of the most important protein families in insects implicated in the endogenous metabolism and detoxification of xenobiotics, including allelochemicals, insecticides and environmental pollutants. To better understand the evolution and function of insect P450s and support the development and application of insecticides for pest control, an integrated bioinformatics platform is highly desirable.

ZIKV prM hijacks PIM1 kinase for phosphorylation to prevent ubiquitin-mediated degradation and facilitate viral replication.

Introduction: Viral infection usually stimulates a variety of host cell factors to modulate the life cycle of the virus. PIM1, a serine/threonine protein kinase widely involved in cell proliferation, survival, differentiation and apoptosis, was recently reported to be upregulated by Zika virus (ZIKV) infection. However, how ZIKV-PIM1 interactions affect the viral life cycle are not fully understood.

Spectroscopic characterization of buffer-gas-cooled lead monofluoride molecules in the BΣ(υ' = 0) ← XΠ(υ = 0) transition.

Establishing a nonzero measurement of the electron Electric Dipole Moment (eEDM) has long been a fundamental pursuit in atomic, molecular and optical physics, offering possible insights into new physics beyond the Standard Model. In this regard, lead monofluoride (PbF) has emerged as a potential candidate for measuring eEDM primarily due to its suitable properties such as the strong internal effective electric field, and eEDM-sensitive ground state with large Ω-doubling and small magnetic g factor. In the present work, we realized the production of a buffer-gas-cooled PbF molecular beam and characterized its high-resolution spectroscopy in the BΣ(υ'=0) ← XΠ(υ = 0) transition, including both direct absorption and laser-induced fluorescence spectroscopy.

Microglia programmed cell death in neurodegenerative diseases and CNS injury.

Programmed cell death (PCD) has emerged as a critical regulatory mechanism in the initiation and progression of various pathological conditions. PCD in microglia, including necroptosis, pyroptosis, apoptosis, ferroptosis, and autophagy, occurs in a variety of central nervous system (CNS) diseases. Dysregulation of microglia can lead to excessive tissue damage or neuronal death in CNS injury.

Comparative efficacy of non-pharmacological management for chronic prostatitis/chronic pelvic pain syndrome: a systematic review and network meta-analysis protocol.

Background: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) has posed a significant burden on affected individuals and healthcare systems. While pharmacological treatments are commonly used, non-pharmacological management strategies have gained attention for their potential benefits in improving CP/CPPS symptoms. However, the comparative efficacy of these non-pharmacological interventions remains unclear.

Confrontation experience against escaping bait improves pursuit strategy in mice.

Confrontations between predator and prey, driven by the innate survival instincts in both predator and prey, constitute the most significant form of competition in evolution. Yet, understanding how survival skills can benefit from such confrontations remains limited, despite its critical importance for animal survival. We have developed an interactive platform to investigate confrontations between a hungry mouse and an escaping bait.

Application of random quality control based on time -series model in ELISA detection of blood donors in Nanjing.

This study introduces a completely Random Quality Control (R-QC) method for Enzyme-Linked Immunosorbent Assay (ELISA) tests and compares it with traditional Fixed Quality Control (F-QC) methods across different testing items. A random quality control system was constructed using a Time-series model, enabling fully random positioning of quality control in ELISA tests. The Coefficient of Variation (CV) for R-QC were found to be lower as compared to F-QC in Hepatitis B surface antigen (HBsAg), anti-Human Immunodeficiency Virus (anti-HIV), and Treponema Pallidum (TP) items, and there were significant differences among them.

Plasma Glutaminyl-Peptide Cyclotransferase Mediates Glucosamine-Metabolism-Driven Protection Against Hypertension: A Mendelian Randomization Study.

Hypertension is one of the major risk factors for morbidity and mortality worldwide. In this study, Mendelian randomization was utilized to investigate how dietary supplement intake can impact hypertension based on circulating plasma metabolite genome-wide association study (GWAS) datasets, protein quantitative trait loci (pQTLs) of plasma proteins, and multiple public summary-level GWAS data. Pathway enrichment analysis combined with the results of inverse variance weighted Mendelian randomization revealed that a lower risk of hypertension was associated with the dietary intake of glucosamine, an anti-inflammatory supplement: odds ratio (OR) (95% CI): 0.

Transcriptome-Based Revelation of the Effects of Sleep Deprivation on Hepatic Metabolic Rhythms in Tibetan Sheep ().

Sleep deprivation (SD) disrupts circadian rhythms; however, its effects on SD and the mechanisms involved require further investigation. Previous studies on SD were mainly conducted on rodents, such as mice, with few studies on its effects on the liver of large diurnal animals, such as sheep. In this study, we used a Tibetan sheep model for the first time to investigate the effects of SD on the liver by exposing Tibetan sheep () to 7 days of SD (6 h/day) and performed transcriptome sequencing analysis on liver samples taken at 4 h intervals over 24 h.

Various assembly strategies are designed to integrate the dual views into the model input, contrasting with the use of single views alone, with a goal to maximize performance.

Huang-Lian-Jie-Du decoction alleviates cognitive impairment in high-fat diet-induced obese mice via Trem2/Dap12/Syk pathway.

Background: Cognitive impairment induced by a high-fat diet (HFD) is common, but its mechanism is largely unknown. Huang-Lian-Jie-Du (HLJD) decoction is a classical and powerful prescription in China. It consists of four medicinal plants and is widely used in traditional Chinese medicines (TCM).

Spermidine mediates acetylhypusination of RIPK1 to suppress diabetes onset and progression.

It has been established that N-acetyltransferase (murine NAT1 (mNAT1) and human NAT2 (hNAT2)) mediates insulin sensitivity in type 2 diabetes. Here we show that mNAT1 deficiency leads to a decrease in cellular spermidine-a natural polyamine exhibiting health-protective and anti-ageing effects-but understanding of its mechanism is limited. We identify that mNAT1 and hNAT2 modulate a type of post-translational modification involving acetylated spermidine, which we name acetylhypusination, on receptor-interacting serine/threonine-protein kinase 1 (RIPK1)-a key regulator of inflammation and cell death.

[Gluteal tendinitis and primary coxarthrosis may lead to iliotibial band syndrome: a Mendelian randomization study].

Objective: To analyze the causal relationship of gluteal tendinitis and primary coxarthrosis with the occurrence of iliotibial band syndrome using Mendelian randomization.

Methods: The GWAS data of gluteal tendinitis, primary coxarthrosis and iliotibial band syndrome were screened for high correlation single-nucleotide polymorphisms (SNPs). Mendelian randomization analysis was performed using random-effects inverse variance weighting (IVW), MR-Egger regression, and weighted median method to determine whether gluteal tendinitis and primary coxarthrosis were causally related with iliotibial band syndrome.

Suppression of non-muscle myosin II boosts T cell cytotoxicity against tumors.

Increasing evidence highlights the importance of immune mechanoregulation in establishing and sustaining tumor-specific cytotoxicity required for desirable immunotherapeutic outcomes. However, the molecular connections between mechanobiological inputs and outputs and the designated immune activities remain largely unclear. Here, we show that partial inhibition of non-muscle myosin II (NM II) augmented the traction force exerted by T cells and potentiated T cell cytotoxicity against tumors.

Genome-Centric Metagenomics Insights into the Plastisphere-Driven Natural Degradation Characteristics and Mechanism of Biodegradable Plastics in Aquatic Environments.

Biodegradable plastics (BPs) are pervasively available as alternatives to traditional plastics, but their natural degradation characteristics and microbial-driven degradation mechanisms are poorly understood, especially in aquatic environments, the primary sink of plastic debris. Herein, the three-month dynamic degradation process of BPs (the copolymer of poly(butylene adipate--terephthalate) and polylactic acid (PLA) (PBAT/PLA) and single PLA) in a natural aquatic environment was investigated, with nonbiodegradable plastics polyvinyl chloride, polypropylene, and polystyrene as controls. PBAT/PLA showed the weight loss of 47.

Dynamic responses of the inter-microbial synergism and thermodynamic conditions attribute to the inhibition-and-relief effects of chitosan towards anaerobic digestion.

Wide commercial applications of chitosan in food preservation and green packaging fields inevitably lead to the universal existence in food, as well as the food waste (FW) processing system. However, whether and how the chitosan, a class of biomacromolecule substances, lead to dysfunction of anaerobic digestion (AD) process of FW remains less understood. Herein, chitosan exhibited an inhibition-and-relief effect with the AD process proceeding, and 80 mg/g-FW of chitosan decreased the net methane yield of FW by 24.

Room-Temperature Flexible CNT/FeO Film Sensor for ppb-Level HS Detection.

Carbon nanotubes (CNTs) had room temperature response, large surface area, and excellent mechanical properties, making them favorable for the design of flexible, wearable, and portable gas sensors. However, CNTs were lacking in response and selective response to different gases, such as HS. Here, we demonstrated a flexible HS ppb-level gas sensor based on a carbon nanotube/amorphous FeO (CNT/FeO) film at room temperature, which was fabricated via a simple one-step solvent-thermal method.
