Low-input CUT&Tag for efficient epigenomic profiling of zebrafish stage I oocytes.

Histone modification signatures mark sites of transcriptional regulatory elements and regions of gene activation and repression. These sites vary among cell types and undergo dynamic changes during development and in diseases. Oocytes produce numerous maternal factors essential for early embryonic development, which are significantly influenced by epigenetic modifications.

Auxiliary identification of depression patients using interpretable machine learning models based on heart rate variability: a retrospective study.

Objective: Depression has emerged as a global public health concern with high incidence and disability rates, which are timely imperative to identify and intervene in clinical practice. The objective of this study was to explore the association between heart rate variability (HRV) and depression, with the aim of establishing and validating machine learning models for the auxiliary diagnosis of depression.

Methods: The data of 465 outpatients from the Affiliated Hospital of Southwest Medical University were selected for the study.

Longitudinal association between ADL disability and depression in middle-aged and elderly: national cohort study.

Background: The decline in daily living abilities (ADL) among older adults is a notable predictor of depressive symptoms and the occurrence of disease. However, the effects of changes in ADL disability on the progression of depression have not been extensively studied.

Objective: This research aims to examine the relationship between current ADL disability and depression in individuals aged 45 and older, as well as to explore how ADL disability influences the progression of depression in later life within China.

Programmed cell death: molecular mechanisms, biological functions, diseases, and therapeutic targets.

Programmed cell death represents a precisely regulated and active cellular demise, governed by a complex network of specific genes and proteins. The identification of multiple forms of programmed cell death has significantly advanced the understanding of its intricate mechanisms, as demonstrated in recent studies. A thorough grasp of these processes is essential across various biological disciplines and in the study of diseases.

The Association Between Causality Orientation and Internet Gaming Disorder, and the Role of Sensation Seeking, Anxiety, and Depression.

Objective: Self-determination theory (SDT) deems that people have three causality orientations: autonomy orientation, control orientation, and impersonal orientation. Previous studies suggested that lower autonomy orientation or higher control and impersonal orientations may be associated with more addictive behaviors. Our study aimed to investigate if these associations exist in Internet gaming disorder (IGD), and if sensation seeking, anxiety, and depression could influence the associations between causality orientations and IGD symptoms.

A new clinical classification of congenital biliary dilatation - HUAXI CBD classification.

Background: Current biliary dilatation (BD) classifications are complex and based on cases including secondary BD, leading to unclear distinctions. Notably, congenital and secondary BD differ in etiology, symptoms, and prognosis.

Objective: To propose a more concise and more suitable classification of congenital biliary dilatation (CBD), and exploring the feasibility and effectiveness of this classification in diagnosis and treatment.

A Huluwa phosphorylation switch regulates embryonic axis induction.

Embryonic axis formation is essential for patterning and morphogenesis in vertebrates and is tightly regulated by the dorsal organizer. Previously, we demonstrated that maternally derived Huluwa (Hwa) acts as a dorsal determinant, dictating axis formation by activating β-catenin signaling in zebrafish and Xenopus. However, the mechanism of activation and fine regulation of the Hwa protein remains unclear.

SCCA and CYFRA 21-1 Reference Intervals for Apparently Healthy Chinese Adults: a Multicenter Cross-Sectional Study.

Background: This study aimed to establish reference intervals for two biomarkers actively utilized in routine annual medical check-ups in China: squamous cell carcinoma antigen (SCCA) and cytokeratin 19 fragment (CYRFA 21-1), and to understand the influence of age, gender, and benign nodule(s) on their levels.

Methods: This prospective multicenter cross-sectional study continuously enrolled apparently healthy adults attending annual medical check-ups at three sites in 2019. Serum SCCA and CYFRA 21-1 levels were measured using electrochemiluminescence immunoassays.

Nanocarriers Targeting Circular RNA ADARB1 Boost Radiosensitivity of Nasopharyngeal Carcinoma through Synergically Promoting Ferroptosis.

Nasopharyngeal carcinoma (NPC) is a common malignant tumor of the head and neck, prevalent in regions such as Southern China and Southeast Asia. Radiotherapy serves as the primary clinical treatment for this carcinoma. However, resistance to radiotherapy is a fundamental cause of treatment failure and patient mortality, with the underlying mechanisms yet to be fully elucidated.

History of tobacco smoking and alcohol use can predict the effectiveness of electroconvulsive therapy in individuals with schizophrenia: A multicenter clinical trial.

Background: Current research has found that factors such as gender, age, and family history can predict the efficacy of electroconvulsive therapy (ECT) in individuals with schizophrenia. In our clinical practice, we anecdotally observed that tobacco smokers and alcohol drinkers with schizophrenia seemed to respond more effectively to ECT than non-smokers and non-drinkers. The current study aimed to examine whether history of tobacco smoking or alcohol consumption serve as indicators for predicting therapeutic efficacy of ECT in individuals with schizophrenia.

Pyroptosis in health and disease: mechanisms, regulation and clinical perspective.

Pyroptosis is a type of programmed cell death characterized by cell swelling and osmotic lysis, resulting in cytomembrane rupture and release of immunostimulatory components, which play a role in several pathological processes. Significant cellular responses to various stimuli involve the formation of inflammasomes, maturation of inflammatory caspases, and caspase-mediated cleavage of gasdermin. The function of pyroptosis in disease is complex but not a simple angelic or demonic role.

Analysis of neutrophil extracellular trap-related genes in Crohn's disease based on bioinformatics.

Crohn's disease (CD) presents with diverse clinical phenotypes due to persistent inflammation of the gastrointestinal tract. Its global incidence is on the rise. Neutrophil extracellular traps (NETs) are networks released by neutrophils that capture microbicidal proteins and oxidases targeting pathogens.

Modified Electroconvulsive Therapy Normalizes Plasma GNA13 Following Schizophrenic Relapse.

Objective: GNA13 is an important member of the G protein family, and its coding gene GNA13 has been identified as one of the risk genes for schizophrenia (SCZ). This study aimed to investigate the relationship between GNA13 levels and the clinical symptoms of SCZ following treatment with modified electroconvulsive therapy (MECT).

Methods: This study recruited 82 SCZ patients and 86 healthy controls (HCs).

Liraglutide combined with routine therapy improves renal function, renal fibrosis, immune status, and prognosis of type 2 diabetes patients.

Objective: To investigate the effect of Liraglutide in conjunction with routine therapy on renal function, renal fibrosis, immune status, and prognosis in patients with diabetes mellitus.

Methods: The clinical data of patients with Type 2 diabetes mellitus (T2DM) treated at the First Affiliated Hospital of Jishou University from March 2021 to March 2022 were retrospectively analyzed. Patients were assigned into a control group (n=42) and a study group (n=42) according to their treatment regimen.

T cell exhaustion in human cancers.

T cell exhaustion refers to a progressive state in which T cells become functionally impaired due to sustained antigenic stimulation, which is characterized by increased expression of immune inhibitory receptors, but weakened effector functions, reduced self-renewal capacity, altered epigenetics, transcriptional programme and metabolism. T cell exhaustion is one of the major causes leading to immune escape of cancer, creating an environment that supports tumor development and metastatic spread. In addition, T cell exhaustion plays a pivotal role to the efficacy of current immunotherapies for cancer.

The left and right hippocampal volume GWAS data sets were downloaded from the UK Biobank, which involved 33 224 participants.
