Abscisic acid insensitive 5 (ABI5) is a pivotal transcription factor in abscisic acid (ABA) signaling, playing an essential role in plant growth and responses to abiotic stress. This key regulator is subject to multifaceted regulation, especially on post-translational mechanisms. Recent research has shed light on the post-translational regulation of ABI5, encompassing both post-translational modifications (PTMs) and the modulation of its transcriptional activity.

Despite substantial advances in the antitumor effects of annonaceous acetogenins (ACGs), the absence of a defined biological action mechanism remains a major barrier to their clinical application. Here, it is found that squamocin effectively depletes both EZH2 and MYC in multiple cancer cell lines, including head and neck squamous cell carcinoma, and gastric and colorectal cancer, demonstrating potent efficacy in suppressing these in vivo tumor models. Through the combination of surface plasmon resonance (SPR), differential scanning fluorimetry (DSF), and cellular thermal shift assay (CETSA), heat shock protein 90α (HSP90α) is identified as the direct binding target of squamocin.

Article Synopsis
  • Ferroptosis, an iron-dependent cell death mechanism, contributes to asthma severity, and electroacupuncture (EA) effectively reduces airway inflammation linked to this process.
  • In a lab setting, researchers manipulated NLRP3 expression in inflamed cells to study its role in ferroptosis and the inflammatory response, measuring various cytokines and protein pathways involved.
  • Results showed that LPS exposure heightened inflammation and ferroptosis through the NLRP3 and JAK2/STAT3 pathways; EA treatment mitigated this by inhibiting NLRP3 activation and reducing related symptoms.

In laboratories, classical fear conditioning and extinction procedures are commonly used to study the behavioral and neural mechanisms underlying fear regulation. Contextual fear conditioning involves the association of an aversive event with the environment where it occurs, which engages the hippocampus and its interactions with the amygdala. The orbitofrontal cortex (OFC), divided into the lateral OFC (lOFC) and medial OFC (mOFC) subregions, plays a crucial role in integrating contextual information from the hippocampus and modulating behavioral responses based on the anticipated outcomes of the context.

Background: Novel airway devices are becoming widely available, yet it is unclear whether the techniques or preferences of airway practitioners for airway management have been impacted. Given these facts, a cross-sectional study of the current status of airway management in mainland China was conducted and compared with previous survey findings.

Methods: The national survey was conducted from November 7 to November 28, 2022.

Article Synopsis
  • - The survey on airway management in China involved 3,783 anesthesiologists and revealed that 34.84% had canceled or delayed surgeries due to difficult airways, with a trend towards more anesthesiologists choosing awake intubation techniques as compared to previous years.
  • - A significant majority (72.96%) of anesthesiologists reported having difficult airway training, with noticeable differences in training participation based on hospital tier, indicating varying levels of preparedness among medical facilities.
  • - The availability of advanced airway tools has increased, but the study highlights the need for continued focus on training and education to further reduce risks associated with difficult airways, as evidenced by a decrease in incidents of brain damage or death. *

Blade cut-out is a common complication when using proximal femoral nail anti-rotation (PFNA) for the treatment of intertrochanteric fractures. Although cement augmentation has been introduced to overcome the cut-out effect, the micromechanics of this approach remain to be clarified. While previous studies have developed finite element (FE) models based on lab-prepared or cadaveric samples to study the cement-trabeculae interface, their demanding nature and inherent disadvantages limit their application.

Background: Asthma is a prevalent respiratory inflammatory disease. Abnormal apoptosis of bronchial epithelial cells is one of the major factors in the progression of asthma. Peripheral benzodiazepine receptors are highly expressed in bronchial epithelial cells, which act as a component of the mitochondrial permeability transition pore to regulate its opening and closing and apoptosis of bronchial epithelial cells.

Objectives: For children with Kawasaki disease (KD) at high risk of developing coronary artery lesions and requiring retreatment with intravenous immunoglobulin (IVIG), the availability of accurate prediction models remains limited because of inconsistent variables and unsatisfactory prediction results. We aimed to construct models to predict patient's probability of IVIG retreatment combining children's individual inflammatory characteristics.

Methods: Clinical manifestations and laboratory examinations of 266 children with KD were retrospectively analysed to build a development cohort data set (DC) and a validation cohort data set (VC).

Purpose: To assess the predictive value of liver stiffness measurement (LSM) and three bleeding risk scoring systems for esophagogastric varices bleeding (EGVB) in patients with hepatitis B cirrhosis during hospitalization.

Methods: In this study, 210 patients who had hepatitis B cirrhosis were selected as the subjects. They were categorized into two groups based on whether EGVB occurred during hospitalization: a bleeding group (70 cases) and a non-bleeding group (140 cases).

Background And Aims: We aimed to define gender-specific, optimal alanine aminotransferase (ALT) cut-off values for the prediction of significant liver histological changes (SLHC) in Chinese patients with grey zone (GZ) chronic hepatitis B (CHB) and normal ALT.

Methods: In a retrospective study, we included 1101 consecutive patients with GZ CHB and normal ALT assigned to training or internal validation cohorts. We included an independent cohort of 842 patients for external validation.

Excessive aggressive migration and invasion are important factors that increase the mortality of cancer patients. Matrix metalloproteinase 13 (MMP13) expression is positively correlated with lung cancer malignancy. However, the mechanism underlying an elevated MMP13 expression is not clearly defined.

Article Synopsis
  • Mitochondria are vital for energy regulation and cell death, and damaged ones are eliminated through mitophagy, which is influenced by pH changes and linked to various diseases.
  • Recent advancements have led to the development of small-molecule fluorescent pH probes that help monitor mitophagy with high selectivity and sensitivity.
  • The review highlights different sensing mechanisms of these probes, explores disease models for mitophagy research, and discusses design requirements and future challenges in the field.

Background And Aims: To determine whether liver stiffness measurement (LSM) indicates liver inflammation in chronic hepatitis B (CHB) with different upper limits of normal (ULNs) for alanine aminotransferase (ALT).

Methods: We grouped 439 CHB patients using different ULNs for ALT: cohort I, ≤40 U/L (439 subjects); cohort II, ≤35/25 U/L (males/females; 330 subjects); and cohort III, ≤30/19 U/L (males/females; 231 subjects). Furthermore, 84 and 96 CHB patients with normal ALT (≤40 U/L) formed the external and prospective validation groups, respectively.

Background And Aims: Aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis-4 index (FIB-4) are widely used to assess liver fibrosis in chronic hepatitis B virus (HBV) infection. Currently, the definition of normal alanine aminotransferase (ALT) is controversial. We aimed to examine the diagnostic value of APRI and FIB-4 in chronic HBV carriers with different upper limits of normal (ULNs) for ALT.
