Background: Major depressive disorder (MDD) has been increasingly understood as a disorder of network-level functional dysconnectivity. However, previous brain connectome studies have primarily relied on node-centric approaches, neglecting critical edge-edge interactions that may capture essential features of network dysfunction.

Methods: This study included resting-state functional MRI data from 838 MDD patients and 881 healthy controls (HC) across 23 sites.

Lenvatinib resistance significantly limits its clinical efficacy and application in the treatment of hepatocellular carcinoma (HCC). Mitofusin 2 (MFN2) is an important GTPase involved in mitochondrial fusion, energy balance and mitophagy. The role and regulatory mechanism of MFN2 in HCC progression and lenvatinib resistance remain unclear.

As a metalloid element with toxic properties, arsenic (As) has been shown to induce liver fibrosis (LF). Activation of hepatic stellate cell (HSC) is a pivotal factors in the progression of LF, yet the key sentinel cells of the liver tissue, Kupffer cell (KC), also exert a central regulatory role in driving LF. However, the specific functions of these cells in As-induced LF remain to be elucidated.

There is a lack of research on hepatitis B virus (HBV) reactivation and prognosis in hepatocellular carcinoma (HCC) patients with undetectable HBV DNA after systemic therapy. This study aims to compare HBV reactivation (HBVr) and prognosis between patients treated with tyrosine kinase inhibitor (TKI) monotherapy and those receiving TKI combined with programmed cell death protein‑1 (PD-1) inhibitors. The retrospective study comprised 877 advanced HCC patients from two medical centers with undetectable HBV DNA, receiving TKI monotherapy (n = 419) or TKI plus PD-1 inhibitors (n = 458).

The cigar wrapper leaves (CWLs), as a symbol of the intrinsic quality and appearance of cigars, reflects the overall quality of the cigar. The Shaoxing-flavored T3 Jiuqu used in Shaoxing wine production contains a large number of high-quality microorganisms, such as molds and yeasts, which play a significant role in enhancing flavor and quality. Among these microorganisms, several positively promote the fermentation of CWLs.

Recently, a PARP1-dependent cell-death process termed "parthanatos" that is driven by DNA damage has emerged as a crucial regulator of tissue homeostasis and tumorigenesis. Hypoxia is a hallmark of solid tumors and profoundly affects the malignant phenotypes of cancer cells. Here, we investigated the crosstalk between parthanatos and hypoxia.

Background: The relationship between specific clusters of prepregnancy cardiovascular risk factors and stillbirth, particularly across racial and ethnic groups, remains understudied. We aimed to evaluate the association between 16 distinct cardiovascular risk clusters and stillbirth, emphasizing racial disparities.

Methods: We conducted a nationwide, population-based study using Centers for Disease Control and Prevention Natality and Fetal Death Data Files (2014-2022), including 31 408 776 singleton births and 131 047 stillbirths (≥20 weeks' gestation).

Introduction: Recently, contrary to attacking cancer cells, the tumor microenvironment (TME) with genomic stability and vulnerable nature has emerged as promising therapeutic targets in hepatocellular carcinoma (HCC). Within TME ecosystem, tumor-associated macrophages (TAMs) play a pivotal role in tumor evasion and progression of HCC. However, their clinical and therapeutic implications remain unexplored.

The feasibility of one-stage laparoscopic-endoscopic rendezvous (LER) strategy in high-risk cholecystocholedocholithiasis (CCL) requires exploration. Prior to the study, 16 items were approved by hospital administrative and clinical departments to address logistic challenges. A total of 51 Patients were analyzed, median operation time, intraoperative bleeding, duration of nasobiliary drainage tube (NBDT), and posthospital stay were 210 min, 20 ml, 8 days and 10 days, respectively.

Objectives: Childhood obesity has emerged as a significant public health challenge and there is an urgent need to improve the effectiveness of local government governance to curb its growth. We aimed to estimate the prevalence and changes of childhood overweight (including obesity) across China and its provinces from 2000 to 2019 and to project the prevalence by 2030, stratified by sex.

Methods: This study utilized data from the Institute for Health Metrics and Evaluation (IHME), which generated local-, administrative-, and national-level estimates of overweight prevalence among children under 5 years of age at a 5 × 5 km resolution for several low- and middle-income countries (LMICs) between 2000 and 2019 using a model-based geostatistical approach.

Urological cancers (UCs) greatly impact global public health. While immunity plays an important role, the contribution of specific immune cell traits to the development of UCs remains unclear. In our study, we employed Mendelian randomization (MR) to elucidate the causal relationship between 731 immune cell traits and three common UCs, namely kidney cancer (KC), bladder cancer (BC), and prostate cancer (PC).

Targeted combined immunotherapy (TCI) has shown certain antitumor effects in patients with unresectable hepatocellular carcinoma(uHCC), but only a subset of patients benefit. This study aims to develop a Transformer-based radiomics model to predict the objective response to combined therapy in patients with uHCC. This multicenter, retrospective study involved 264 HCC patients who underwent contrast-enhanced MRI prior to immunotherapy.

Metal-organic frameworks (MOFs) composed of infinite metal units exhibit enhanced electron transport and charge migration capabilities compared to discrete metal units. Herein, three underdeveloped isomorphic MOFs featuring 3D infinite zinc units are designed and synthesized. The Lewis acidity and photocatalytic activity of these MOFs are fine-tuned through atomic-level engineering of nitrogen atoms of ligands and the resultant change of charge transfer modes.

Background: Combination therapy of anti-PD-1 plus lenvatinib has shown effective anti-tumour effects for unresectable hepatocellular carcinoma (HCC), but the overall prognosis of HCC is still unsatisfactory. Elucidating the molecular mechanism underlying HCC progression contributes to develop new effective treatment in order to enhances the response of anti-PD-1 plus lenvatinib therapy and improve the patients prognosis.

Method And Results: Here, we reported that targeting SAMD1 in HCC cells via small interference RNA-containing ZIF-90@HA (ATP/acid-responsive) Nanoparticles (ZIF-90@siRNA@HA NPs, ZSH NPs) significantly enhanced the anti-tumour effects of anti-PD-1 plus lenvatinib in vivo.

Ferroelectric materials are promising for developing non-volatile memory, neuromorphic computing, and photovoltaic technologies. Taking advantage of variable switching kinetics provides an important strategy for designing multifunctional ferroelectric devices. However, the conventional ferroelectrics due to the unmovable atomic species generally own a single switching kinetics, thus versatile and configurable switching kinetics still remain challenging.
