The NLRP3 inflammasome plays a critical role in various inflammatory conditions. However, despite extensive research in targeted drug development for NLRP3, including MCC950, clinical success remains elusive. Here, we discovered that the activated NLRP3 inflammasome complex (disc-NLRP3) and the activating mutation L351P exhibited resistance to MCC950.

Although pollution during crude oil production has been paid attention, there is lack of studies on organic pollutants generated/emitted from oil-production wastewater (OPW) treatment processes, especially advanced oxidation process. Based on GC-Q-Orbitrap-HRMS, the present study performed non-target analysis of volatile/semi-volatile organic compounds in physical and electro-oxidation units of OPW treatment stations located in Shengli Oilfield of China. Overall, 64-227 organic compounds were respectively identified in different units, and electro-oxidation was found elevating (by 2.

In deep formations, oil or gas reservoir rocks are generally accompanied by groundwater with high total dissolved solids (TDS), commonly referred to as "formation water". The enrichment of trace and/or metallic elements such as K, B, Li, Br, Sr in this type of groundwater holds significant industrial values and socioeconomic benefits. However, the processes involved in the burial and generation of formation water remain not fully understood.

We have previously found that the DAPK-DDX20 signaling axis exerts an anti-cancer activity in hepatocellular carcinoma (HCC) by inhibiting the GTPase activity of CDC42, thereby reducing the invasive and migratory capabilities of cancer cells without affecting cell proliferation. DDX20 serves as an intermediate protein regulated by DAPK in the control of CDC42. Specifically, DAPK enhances DDX20 protein levels by suppressing DDX20 degradation.

  • Chronic hepatitis B virus (HBV) infection is a significant public health issue, with viral cccDNA being crucial for HBV replication and life cycle, particularly influenced by the HBx protein.* -
  • The study identified VCPIP1, a deubiquitinating enzyme, as a key host protein that interacts with HBx, stabilizing it and enhancing HBV transcription and replication even in the absence of HBx.* -
  • VCPIP1 also positively affects HBV promoter and enhancer activities, indicating its role as a multi-functional regulator in the life cycle of the virus.*

Background: Previous studies have shown that migraines are associated with brain structural changes. However, the causal relationships between these changes and migraine, as well as its subtypes, migraine with aura (MA) and migraine without aura (MO), remain largely unclear.

Methods: We utilized genome-wide association study (GWAS) summary statistics from European cohorts for 2,347 cortical structural magnetic resonance imaging (MRI) phenotypes, derived from both T1-weighted and diffusion tensor imaging scans (n = 36,663), with migraine and its subtypes (n = 147,970-375,752).

Article Synopsis
  • Recent research indicates that a high salt diet (HSD) is associated with increased inflammation and decreased extracellular matrix (ECM) in the skin, leading to accelerated skin aging in mice.
  • In a study with Wistar rats, those on an HSD for 8 weeks showed thickened epidermis and changes in molecular markers linked to aging, including elevated levels of cell cycle inhibitors and oxidative stress.
  • By the end of the study, significant increases in inflammatory molecules were observed in the HSD group, suggesting that high salt intake contributes to skin aging through oxidative stress and inflammatory responses.

  • The study explores sex-specific differences in metabolic abnormalities in first-episode antipsychotics-naïve schizophrenia (FEAN-SCZ), focusing on glucose and lipid profiles in patients.
  • A total of 172 FEAN-SCZ patients (83 males, 89 females) and 31 healthy controls were assessed for psychopathology and underwent glycolipid profiling.
  • Results showed that both male and female FEAN patients had higher glucose levels than controls, with distinct lipid profile changes observed in males with impaired glucose tolerance, highlighting the need for tailored metabolic assessments in treatment.*

Article Synopsis
  • - Insects can become resistant to insecticides through the overexpression of P450 enzymes, which detoxify these chemicals, and G-protein-coupled receptors (GPCRs) have been identified as important regulators in this process.
  • - This study discovered two rhodopsin-like GPCR genes that were overexpressed in insecticide-resistant strains, indicating a possible link to enhanced resistance mechanisms.
  • - Overexpressing these GPCR genes in a transgenic model led to a two-fold increase in resistance to permethrin, suggesting that they play a significant role in regulating P450 genes involved in insecticide detoxification.

Background: The increasing spread of mosquito-borne diseases is a significant problem globally, but mosquito management strategies are less efficient. Therefore, a comprehensive understanding of the population dynamics of Aedes mosquito is essential for improving mosquito management strategies. Constructing a model to understand Aedes mosquito development in response to environmental factors is crucial to addressing these challenges.

A sufficiently high current output of nano energy harvesting devices is highly desired in practical applications, while still a challenge. Theoretical evidence has demonstrated that Coulomb drag based on the ion-electron coupling interaction, can amplify current in nanofluidic energy generation systems, resulting in enhanced energy harvesting. However, experimental validation of this concept is still lacking.

Cisplatin resistance in ovarian cancer cells is mainly apoptosis resistant. Although other types of programmed cell death are highly involved in chemoresistance, which type can overcome cisplatin resistance remains unclear. The present study observed that cisplatin-sensitive SKOV3 cells and cisplatin-resistant SKOV3/DDP cells had different levels of sensitivity to sulfasalazine (SAS).

Antimicrobial resistance (AMR) is a major threat to public health worldwide. It is a promising way to improve appropriate prescription by the review and stewardship of antimicrobials, and Post-Prescription Review (PPR) is currently the main tool used in hospitals. Existing methods of PPR typically focus on the dichotomy of antimicrobial prescription based on binary classification which, however, is usually a multi-label classification problem.
