Light-Directed Self-Powered Metal-Organic Framework Based Nanorobots for Deep Tumor Penetration.

Effective intratumoral distribution of anticancer agents with good tumor penetration is of great practical importance for oncotherapy. How to break the limitation of traditional passive drug delivery relying on blood circulatory system into solid tumors remains a challenge. Herein, a light-directed self-powered nanorobot based on zirconium-based porphyrin metal-organic framework (MOF) is reported for smart delivery of chemodrug and photosensitizer for deep tumor penetration.

Mechanism of cognitive processing for acupuncture action on generalized anxiety with naturally occurring consecutive partial sleep deprivation in early adulthood: a randomized controlled study and evaluation of event-related potentials.

Introduction: Generalized anxiety disorder (GAD) is a common mental disorder that often begins in adolescence or early adulthood and is characterized by widespread and persistent anxiety. Partial sleep deprivation (PSD) is an important risk factor for GAD development and a common comorbidity. Adolescence is a period of rapid brain and nervous system development, and during this time, the occurrence of GAD can lead to neurocognitive deficits, such as impaired attention, cognitive control, and attention bias, that significantly affect cognitive function.

Electroacupuncture ameliorates depression-like behaviors in rats with post-stroke depression by inhibiting ferroptosis in the prefrontal cortex.

Introduction: Post-stroke depression (PSD) is the most common complication following a stroke, significantly hindering recovery and rehabilitation in affected patients. Despite its prevalence, the pathogenesis of PSD remains poorly understood. Electroacupuncture (EA) has shown antidepressant effects, yet its neuroprotective properties are not well defined.

Objectives: This study aims to investigate the biological role and underlying mechanism of mA methylation in photoaging.

Unlocking multi-photon excited luminescence in pyrazolate trinuclear gold clusters for dynamic cell imaging.

The family of coinage-metal-based cyclic trinuclear complexes exhibits abundant photophysical properties, promising for diverse applications. However, their utility in biochemistry is often hindered by large particle size and strong hydrophobicity. Meanwhile, the investigation into multi-photon excited luminescence within this family remained undocumented, limiting their potential in bio-imaging.

The effect of narrative nursing on improving the negative emotions and quality of life of patients with moderate to severe cancer pain.

Objective: This study aimed to explore the effect of narrative nursing on improving the negative emotions, sleep quality, and quality of life of patients with moderate to severe cancer pain.

Methods: A total of 80 patients with moderate to severe cancer pain who had been hospitalized in the lymphoma oncology department in our hospital from March 2019 to September 2021 were selected as the study subjects and randomly divided into the conventional nursing and narrative nursing groups, with 40 cases in each group. A conventional nursing intervention was conducted for one group, and narrative nursing was provided for the second group in addition to the conventional nursing.

The causal effect of adipose tissue on Hodgkin's lymphoma: two-sample Mendelian randomization study and validation.

Background: Extensive research has been conducted on the correlation between adipose tissue and the risk of malignant lymphoma. Despite numerous observational studies exploring this connection, uncertainty remains regarding a causal relationship between adipose tissue and malignant lymphoma.

Methods: The increase or decrease in adipose tissue was represented by the height of BMI.

Inhibitory Effects of Soluble Dietary Fiber from Foxtail Millet on Colorectal Cancer by the Restoration of Gut Microbiota.

Colorectal cancer (CRC) is a common malignant tumor that occurs in the colon. Gut microbiota is a complex ecosystem that plays an important role in the pathogenesis of CRC. Our previous studies showed that the soluble dietary fiber of foxtail millet (FMB-SDF) exhibited significant antitumor activity in vitro.

Targeted Linked-Read Sequencing for Direct Haplotype Phasing of Parental GJB2/SLC26A4 Alleles: A Universal and Dependable Noninvasive Prenatal Diagnosis Method Applied to Autosomal Recessive Nonsyndromic Hearing Loss in At-Risk Families.

Noninvasive prenatal diagnosis (NIPD) for autosomal recessive nonsyndromic hearing loss (ARNSHL) has been rarely reported until recent years. Additionally, the existing method can not be used for challenging genome loci (eg, copy number variations, deletions, inversions, or gene recombinants) or on families without proband genotype. This study assessed the performance of relative haplotype dosage analysis (RHDO)-based NIPD for identifying fetal genotyping in pregnancies at risk of ARNSHL.

Validation of CDC45 as a novel biomarker for diagnosis and prognosis of gastric cancer.

Background: Cell division cycle protein 45 (CDC45) has been demonstrated to play vital roles in the progression of various malignancies. However, the clinical significance of CDC45 in gastric cancer (GC) remains unreported.

Method: In this study, we employed the TCGA database and the TCGA & GTEx dataset to compare the mRNA expression levels of CDC45 between gastric cancer tissues and adjacent or normal tissues ( < 0.

On-Site Ratiometric Analysis of UO with High Selectivity.

Uranyl ions (UO) are recognized as important indicators for monitoring sudden nuclear accidents. However, the interferences coexisting in the complicated environmental matrices impart serious constraints on the reliability of current on-site monitoring methods. Herein, a novel ratiometric method for the highly sensitive and selective detection of UO is reported based on a [Eu(diaminoterephthalic acid)] (Eu-DATP) metal-organic framework.

Neoadjuvant nivolumab plus bevacizumab therapy improves the prognosis of triple-negative breast cancer in humanized mouse models.

Background: The combination of immune checkpoint inhibitors and anti-angiogenic agents has been proposed as a promising strategy to improve the outcome of advanced triple-negative breast cancer (TNBC). However, further investigation is warranted to elucidate the specific mechanisms underlying the effects of combination therapy and its potential as neoadjuvant therapy for early-stage TNBC.

Methods: In this study, we constructed humanized mouse models by engrafting the human immune system into severely immunodeficient mice and subsequently implanting TNBC cells into the model.

The transcription factor ZEB2 drives the formation of age-associated B cells.

Age-associated B cells (ABCs) accumulate during infection, aging, and autoimmunity, contributing to lupus pathogenesis. In this study, we screened for transcription factors driving ABC formation and found that zinc finger E-box binding homeobox 2 (ZEB2) is required for human and mouse ABC differentiation in vitro. ABCs are reduced in haploinsufficient individuals and in mice lacking in B cells.

Hydrogen sulfide regulates arsenic-induced cell death in yeast cells by modulating the antioxidative system.

Arsenic (As) is a metal with potentially toxic effects on different organisms. Hydrogen sulfide (HS) plays a vital role in mitigating heavy metal toxicity by reducing oxidative stress in plants and animals. However, the role of HS in alleviating arsenic toxicity in yeast cells remains unclear.

Rapid analysis of dichlorvos via releasing the phosphate core.

Monitoring the residual dichlorvos (O,O-dimethyl-O-2,2-dichlorovinylphosphate, DDVP) in food has received extensive attention owing to its large consumption in agriculture. However, the previous sensing methods are not time-efficient enough due to the long incubation time for enzyme inhibition (tens of minutes to hours) or bottlenecked by the complicated procedures for senor fabrication. Herein, a novel sensing strategy is proposed based on the hydrolysis of DDVP into PO.
