Many physiological processes in the human body are initiated by mechanical signals, which are transmitted via ion channels. Piezo-type mechanosensitive ion channel component 1 (Piezo1) is a protein highly expressed in the brain, playing a critical role in sensing changes in the mechanical microenvironment. Extensive research has demonstrated that Piezo1 is an essential component for generating currents in mechanically activated cation channels.

Pathologic myopia is a leading cause of visual impairment and blindness. While deep learning-based approaches aid in recognizing pathologic myopia using color fundus photography, they often rely on implicit patterns that lack clinical interpretability. This study aims to diagnose pathologic myopia by identifying clinically significant morphologic patterns, specifically posterior staphyloma and myopic maculopathy, by leveraging ultra-widefield (UWF) images that provide a broad retinal field of view.

Background: Patients with type 2 diabetes mellitus (T2DM) face a heightened risk of future cardiovascular events. It is therefore important to stratify these patients according to their future cardiovascular event risk to allow early intervention and improve prognosis. Recent proposals have indicated that nontraditional lipoprotein ratios may be superior predictors of cardiovascular events compared to traditional lipid parameters.

Hepatocellular carcinoma (HCC) is characterized by poor prognosis and remains a leading cause of cancer mortality worldwide. Advanced HCC is managed with several first-line therapies, including tyrosine kinase inhibitors (TKI) and immunotherapy (mAb-PD-1 and mAb-VEGF). However, the efficacy of HCC therapeutics is often short-lived.

Patients with advanced cancer frequently endure severe pain, which substantially diminishes their quality of life and can adversely impact survival. Analgesia, a critical modality for alleviating such pain, is now under scrutiny for its potential role in cancer progression, a relationship whose underlying mechanisms remain obscure. Emerging evidence suggests that lactate, once considered a metabolic byproduct, actively participates in the malignant progression of cancer by modulating both metabolic and immunological pathways within the tumor microenvironment.

Background: Recent studies have indicated that triglyceride glucose (TyG)-waist height ratio (WHtR) and TyG-waist circumference (TyG-WC) are effective indicators for evaluating insulin resistance. However, research on the association in TyG-WHtR, TyG-WC, and the risk and prognosis of major adverse cardiovascular events (MACEs) in type 2 diabetes mellitus (T2DM) cases are limited.

Aim: To clarify the relation in TyG-WHtR, TyG-WC, and the risk of MACEs and overall mortality in T2DM patients.

Background: The intracellular bacterium Listeria monocytogenes is an attractive vector for cancer immunotherapy as it can effectively deliver tumor antigens to antigen-presenting cells, leading to a robust antitumor response.

Results: In this study, we developed a novel vaccine platform called Listeria-based Live Attenuated Double Substitution (LADS), which involves introducing two amino acid substitutions (N478AV479A) into the virulence factor listeriolysin O (LLO). LADS is a safe vaccine platform, with an attenuation of nearly 7000-fold, while retaining complete immunogenicity due to the absence of deletion of any virulence factors.

Article Synopsis
  • This study explores how Listeria monocytogenes manipulates host mitochondrial dynamics, specifically fission and fusion, to boost its pathogenicity.
  • *The virulence factor listeriolysin O (LLO) interacts with Mic60, a key component of mitochondrial structure, causing mitochondrial fragmentation that aids in bacterial infection.
  • *The research reveals Mic60's role in altering mitochondrial morphology and function during L. monocytogenes infection, suggesting new avenues for treating bacterial infections.

Aim: To explore the association between the non-high-density lipoprotein cholesterol (HDL-C)/HDL-C ratio (NHHR) and the risk of major adverse cardiovascular events (MACEs) and overall mortality in patients with type 2 diabetes mellitus (T2DM).

Materials And Methods: NHHR, calculated as (total cholesterol - HDL-C)/HDL-C, was evaluated in 10,188 participants. Cox proportional hazard regression models were employed to assess the association of NHHR with future risk of MACEs and overall mortality.

Ethnopharmacological Relevance: Cognitive dysfunction associated with diabetes, known as diabetic encephalopathy (DE), is a grave neurodegenerative condition triggered by diabetes, and persistent inflammation plays a vital role in its development. The renowned traditional Chinese medicine Huang-Lian-Jie-Du Decoction (HLJDD) is clinically proven to manage diabetes mellitus and Alzheimer's disease and is famous for its heat-clearing and detoxifying effects. However, the underlying mechanisms through which HLJDD affects DE remain to be elucidated.

Article Synopsis
  • RAN is a key issue in developmental dyslexia (DD) that involves multiple brain regions working together, but the specific brain connectivity factors affecting RAN in Chinese children with DD are not well understood.
  • A study involving 36 children with DD and 64 typically developing (TD) children used resting-state fMRI scans and Granger causality analysis to investigate the effective connectivity (EC) between brain areas associated with RAN.
  • The findings indicate that children with DD showed decreased EC in several brain area connections essential for RAN performance, suggesting a core deficit while also displaying some compensatory mechanisms, which highlights the need for targeted brain-based interventions.

Digital PCR is a powerful method for absolute nucleic acid quantification and is widely used in the absolute quantification of viral copy numbers, tumor marker detection, and prenatal diagnosis. However, for most of the existing droplet-based dPCR systems, the droplet generation, PCR reaction, and droplet detection are performed separately using different instruments. Making digital PCR both easy to use and practical by integrating the qPCR workflow into a superior all-in-one walkaway solution is one of the core ideas.

Diabetic cardiomyopathy (DCM) contributes significantly to the heightened mortality rate observed among diabetic patients, with myocardial fibrosis (MF) being a pivotal element in the disease's progression. Hydrogen sulfide (HS) has been shown to mitigate MF, but the specific underlying mechanisms have yet to be thoroughly understood. A connection has been established between the evolution of DCM and the incidence of cardiomyocyte pyroptosis.
