Lateralization of the Aberrant Amplitude of Low-Frequency Fluctuation within the Default Mode Network in Patients with Mild Cognitive Impairment.

Rationale And Objectives: Alzheimer's disease (AD) is the most common pathogenesis of dementia, and mild cognitive impairment (MCI) is considered as the intermediate stage from normal elderly to AD. Early detection of MCI is an essential step for the timely intervention of AD to slow the progression of this disease. Different form previous studies in the whole-brain spontaneous activities, this research aimed to explore the low-frequency amplitude spectrum activities of patients with MCI within the default mode network (DMN), which has been involved in the process of maintaining normal cognitive function.

We constructed the PLA2R1 knockout [PLA2R1(-)] model and PLA2R1 knock in [PLA2R1(+)] model in rats.

Prognostic Value of LV Global Longitudinal Strain by 2D and 3D Speckle-Tracking Echocardiography in Patients With HFpEF.

Background: In patients with heart failure with preserved ejection fraction (HFpEF), the impact of type 2 diabetes (T2D) on left ventricular global longitudinal strain (LV GLS) and its prognostic implications remains unclear. We aimed to evaluate LV function using two-dimensional (2D) and three-dimensional (3D) speckle-tracking echocardiography in patients with HFpEF with and without T2D, and to investigate its prognostic significance.

Methods: A total of 335 patients with HFpEF were prospectively enrolled for echocardiographic evaluation.

Tyrosinase-Catalyzed Peptide Stapling Using Para-Amino Phenylalanine and Tyrosine Anchoring Residues.

Peptide stapling techniques have historically relied on metal-catalyzed chemical reactions, with no examples using enzymes. Here, inspired by tyrosinase-mediated oxidation, we describe the efficient side-chain to side-chain coupling of p-amino phenylalanine (Z) and tyrosine (Y) amino acids using a commercially available tyrosinase. Stapling reactions between the i, i+3 to i, i+7 positions were all performed, proceeding in good conversion and under mild conditions compatible with various side chains, functional motifs and ring sizes, with the Z-Y product found to be more stable and obtained in a higher yield than the Y-Z product.

A Preclinical Immunogenicity Study of the Recombinant Human Papillomavirus Nine-Valent Virus-like Particle Vaccine.

Background: Cervical cancer is associated with persistent infection of high-risk human papillomaviruses (HPVs). Prophylactic HPV vaccines have been recommended and have significant efficacy in preventing cervical cancer. Multivalent HPV vaccines have a better preventative effect on HPV-related diseases.

Bivalent SMAC mimetic APG-1387 reduces HIV reservoirs and limits viral rebound in humanized mice.

Latent viral reservoirs (VRs) represent a main barrier to HIV cure. Thus, developing new approaches that can purge and eliminate VRs paves the path toward achieving an HIV-1 cure. APG-1387, a bivalent SMAC mimetic (SM), efficiently reactivates latent HIV expression in T cell line models and enhances active caspase 3 expression, a condition that typically leads to apoptosis.

The Benefits of Virtual Reality Travel on Symptom Burden and Mental Health of Hemodialysis Patients.

Context: Hemodialysis (HD) patients often face a heavy symptom burden, low subjective well-being, and high perceived stress. Traditional nonpharmacological interventions have limited effectiveness in improving this situation. Virtual reality (VR) technology, as an emerging approach, has shown significant advantages in alleviating symptom burden and enhancing mental health.

Diagnosis of liver hemangioma using magnetic resonance diffusion-derived vessel density (DDVD) pixelwise map: a preliminary descriptive study.

Background: Liver hemangiomas (HGs) are characterized by cavernous venous spaces delineated by a lining of vascular endothelial cells and interspersed with connective tissue septa. Typically, a liver HG has higher apparent diffusion coefficient (ADC) and T2 values than those of hepatocellular carcinomas (HCCs) and liver metastases, and lower ADC and T2 values than those of liver simple cysts. However, a portion of HGs shows ADC and T2 overlapping with those of HCC, liver metastasis, and simple cyst.

Background: Mitochondrial dysfunction is a key factor in the development of atherogenesis. METTL4 (methyltransferase-like protein 4) mediates N6- methyldeoxyadenosine (6mA) of mammalian mitochondrial DNA (mtDNA). However, the role of METTL4-mediated mitoepigenetic regulation in atherosclerosis is still unknown.

Single-cell data-driven design of armed oncolytic virus to boost cooperative innate-adaptive immunity against cancer.

Oncolytic viruses have been considered promising cancer immunotherapies. However, oncovirotherapy agents impart durable responses in only a subset of cancer patients. Thus, exploring the cellular and molecular mechanisms underlying the heterogeneous responses in patients can provide guidance to develop more effective oncolytic virus therapies.

Predicting High-risk Lung Adenocarcinoma in Solid and Part-solid Nodules on Low-dose CT: A Multicenter Study.

Rationale And Objectives: High-grade patterns, visceral pleural invasion, lymphovascular invasion, spread through air spaces, and lymph node metastasis are high-risk factors and associated with poor prognosis in lung adenocarcinomas (LUADs).

Materials And Methods: This study retrospectively enrolled 658 pathologically confirmed LUADs from July 2018 to December 2022 from four centers, which were divided into training set (n=411), internal validation set (n=139), and external validation set (n=108).

DCBLD1 Modulates Angiogenesis by Regulation of the VEGFR-2 Endocytosis in Endothelial Cells.

Background: Unwanted angiogenesis is involved in the progression of various malignant tumors and cardiovascular diseases, and the factors that regulate angiogenesis are potential therapeutic targets. We tested the hypothesis that DCBLD1 (discoidin, CUB, and LCCL domain-containing protein 1) is a coreceptor of VEGFR-2 (vascular endothelial growth factor receptor-2) and modulates angiogenesis in endothelial cells.

Methods: A carotid artery ligation model and retinal angiogenesis assay were used to study angiogenesis using globe knockout or endothelial cell-specific conditional knockout mice in vivo.
