Machine learning-based on cytotoxic T lymphocyte evasion gene develops a novel signature to predict prognosis and immunotherapy responses for kidney renal clear cell carcinoma patients.

Background: Immunotherapy resistance has become a difficult point in treating kidney renal clear cell carcinoma (KIRC) patients, mainly because of immune evasion. Currently, there is no effective signature to predict immunotherapy. Therefore, we use machine learning algorithms to construct a signature based on cytotoxic T lymphocyte evasion genes (CTLEGs) to predict the immunotherapy responses of patients, so as to screen patients effective for immunotherapy.

Ultrasound mediated gold nanoclusters-capped gas vesicles for enhanced fluorescence imaging.

The intercellular tight junction inhibits tumor imaging efficiency of nanomaterials, and enhanced cellular drug delivery with efficient detection is an important tool for tumor diagnosis. Herein, we fabricate fluorescence gold nanoclusters (Au NCs) decorated gas vesicles (GV-Au) for ultrasound (US)-mediated enhanced cellular delivery and imaging, in which GVs are living cell derived protein bubbles. GV-Au is rod-shaped sack-like structure around 230 nm, and displays improved stability and fluorescence ability compared with free Au NCs.

Putative causal inference for the relationship between obesity and sex hormones in males: a bidirectional Mendelian randomization study.

Background: Obesity is a chronic disease with a high prevalence rate and is an established risk factor for human health. Body mass index (BMI) is a common and primary indicator used in assessing obesity. This work aims to investigate the putative causal relationship among BMI, sex hormone-binding globulin (SHBG), bioavailable testosterone (BioT), and estradiol levels.

Characteristics and molecular mechanism of drug-tolerant cells in cancer: a review.

Drug resistance in tumours has seriously hindered the therapeutic effect. Tumour drug resistance is divided into primary resistance and acquired resistance, and the recent study has found that a significant proportion of cancer cells can acquire stable drug resistance from scratch. This group of cells first enters the drug tolerance state (DT state) under drug pressure, and gradually acquires stable drug resistance through adaptive mutations in this state.

MiR-181c-5p ameliorates learning and memory in sleep-deprived mice via HMGB1/TLR4/NF-κB pathway.

Sleep deprivation (SD) can lead to cognitive impairment caused by neuroinflammation. MiR-181c-5p/HMGB1 axis plays a part in anti-inflammation effects. However, the mechanism that miR-181c-5p facilitates learning and memory in SD mice remains unclear.

Four modifiable factors that mediate the effect of educational time on major depressive disorder risk: A network Mendelian randomization study.

Objective: To underscore the paramount significance of incorporating comprehensive rehabilitation therapy as a crucial aspect of managing lymphedema caused by breast cancer surgery, and to illuminate our first-hand experience and insights gained in utilizing this approach.

Methods: We present a case report of a breast cancer survivor who had been suffering from persistent left upper-limb edema for over 15 years, who was effectively treated with a combination of conventional rehabilitation (seven-step decongestion therapy) and a comprehensive rehabilitation program (seven-step decongestion therapy, along with core and respiratory function training, as well as functional brace wearing). The efficacy of the rehabilitation therapy was evaluated through a comprehensive assessment.

Liver fibrosis is a serious stage of chronic liver injury. Inhibition of hepatic stellate cells activation and hepatocytes apoptosis is important measures in the treatment of liver fibrosis. Studies have shown that exosomes are involved in regulating the information transmission between cells, but there are few studies on the interaction between exosomes from HSC and hepatocytes.

Association of TyG index with prostate-specific antigen (PSA) in American men: results from NHANES, 2003-2010.

Background: In recent years, triglyceride-glucose index (TyG) was a new indicator of insulin resistance, and it has been widely reported that it may be associated with serum prostate-specific antigen (PSA) concentrations.

Aims: We intended to investigate the possible connection between serum PSA concentration and the TyG index.

Methods: This is a cross-sectional study of adults with complete data on TyG and serum PSA concentrations (ng/ml) from the NHANES, 2003-2010.

The overexpression and clinical significance of TBX15 in human gliomas.

T-box transcription factor 15 (TBX15) is upregulated in a variety of tumors and has been reported to promote uncontrolled proliferation of tumor cells and induce tumor cells to avoid apoptosis, thus accelerating the malignant transformation of malignant tumors. However, the prognostic value of TBX15 in glioma and its relationship with immune infiltration remain unknown. In this study, we intended to explore the prognostic value of TBX15 and its link to glioma immune infiltration and examine TBX15 expression in pan-cancer using RNAseq data in TPM format from TCGA and GTEx.

A review of deubiquitinases and thier roles in tumorigenesis and development.

Ubiquitin is a small protein that can be added onto target protein for inducing target degradation, thereby modulating the activity and stability of protein. Relatively, deubiquitinases (DUBs), a class catalase that can remove ubiquitin from substrate protein, provide a positive regulation of the protein amount at transcription level, post-translational modification, protein interaction, The reversible and dynamic ubiquitination-deubiquitination process plays an essential role in maintaining protein homeostasis, which is critical to almost all the biological processes. Therefore, the metabolic dysregulation of deubiquitinases often lead to serious consequences, including the growth and metastasis of tumors.

Association between smoking and intracranial artery dissection in patients aged less than 50 years: A propensity score-matched analysis.

Introduction: Smoking is a common risk factor for stroke in the young population. Intracranial artery dissection (ICAD) is a major cause of stroke in this population. However, the association between smoking and ICAD in young patients is not well characterized.

Glial cells: an important switch for the vascular function of the central nervous system.

In this review, we first describe the current understanding of glial-mediated vascular function affecting the role of the blood-brain barrier (BBB) in central nervous system (CNS) disorders. BBB, mainly composed of glial and endothelial cells (ECs), is the protective structure that orchestrates the transport of substances, including ions, molecules, and cells from brain vessels into or out of the CNS. Then, we display the multiple communication between glial and vascular function based on angiogenesis, vascular wrapping, and blood perfusion in the brain.

Diagnostic value of liver contrast-enhanced ultrasound in early hepatocellular carcinoma: a systematic review and meta-analysis.

Background: Hepatocellular carcinoma is the sixth most common cancer in the world, and its incidence rate will continue to increase. Contrast-enhanced ultrasound (CEUS) is feasible as a rapid examination for early hepatocellular carcinoma diagnosis. However, considering the possible causes of false positives caused by ultrasound, its diagnostic value is still controversial.

Incidence rate and risk factors of ventilator-associated pneumonia in patients with traumatic brain injury: a systematic review and meta-analysis of observational studies.

Background: Ventilator-associated pneumonia is a common complication of traumatic brain injury (TBI) patients, causing great harm to the life, health and society of patients. It is important to understand the risk factors related to ventilator-associated pneumonia for infection monitoring and control of patients. However, there are still some controversies about the risk factors in previous studies.

Non-human primate models and systems for gait and neurophysiological analysis.

Brain-computer interfaces (BCIs) have garnered extensive interest and become a groundbreaking technology to restore movement, tactile sense, and communication in patients. Prior to their use in human subjects, clinical BCIs require rigorous validation and verification (V&V). Non-human primates (NHPs) are often considered the ultimate and widely used animal model for neuroscience studies, including BCIs V&V, due to their proximity to humans.
