Tetrahedral Framework Nucleic Acid Relieves Sepsis-Induced Intestinal Injury by Regulating M2 Macrophages.

This study aimed to clarify the role and mechanism of tetrahedral framework nucleic acids (tFNAs) in regulating M2 macrophages to reduce intestinal injury. An intestinal injury model was established by intraperitoneal injection of lipopolysaccharides (LPS) in mice to explore the alleviating effects of tFNAs on intestinal injury. Inflammatory factors were detected by quantitative polymerase chain reaction (qPCR) and enzyme-linked immunosorbent assay (ELISA).

Neuroimaging stratification reveals the striatal vulnerability to stress as a risk for schizophrenia.

The striatum, a core brain structure relevant for schizophrenia, exhibits heterogeneous volumetric changes in this illness. Due to this heterogeneity, its role in the risk of developing schizophrenia following exposure to environmental stress remains poorly understood. Using the putamen (a subnucleus of the striatum) as an indicator for convergent genetic risk of schizophrenia, 63 unaffected first-degree relatives of patients (22.

WWC proteins-mediated compensatory mechanism restricts schwannomatosis driven by loss of function.

NF2-related schwannomatosis, previously known as neurofibromatosis type 2, is a genetic disorder characterized by nerve tumors due to gene mutations. Mice with deletion develop schwannomas slowly with low penetrance, hence inconvenient for preclinical studies. Here, we show that NF2, by recruiting E3 ubiquitin ligases β-TrCP1/2, promotes WWC1-3 ubiquitination and degradation.

Altered asymmetry of amygdala volume mediates food addiction and weight gain.

Background: Food addiction and an impulsive personality can increase overeating, which can lead to weight gain. The amygdala and nucleus accumbens (NAcc) are critical for regulating obesogenic behaviour. However, whether the amygdala or the NAcc acts as the neural basis for the regulation of food addiction, impulsive personality, and body weight remains unclear.

Kinetic-pharmacodynamic model to predict post-rituximab B-cell repletion as a predictor of relapse in pediatric idiopathic nephrotic syndrome.

Purpose: Rituximab has proven efficacy in children with idiopathic nephrotic syndrome (INS). However, vast majority of children inevitably experience relapse with B-cell repletion, necessitating repeat course of rituximab, which may increase the risk of adverse effects. The timing of additional dosing and optional dosing regimen of rituximab in pediatric patients with INS have yet to be determined.

Using multimodal ultrasound technology to improve the success rate of liver tumor puncture for lesions with poor visibility on conventional ultrasound imaging.

Background: The ability of conventional ultrasound (US)-guided liver biopsy to visualize certain liver lesions, particularly those affected by conditions like hepatitis or cirrhosis, which can obscure lesion boundaries and lead to inaccurate biopsy targeting, is limited. This study aimed to evaluate the potential of multimodal US techniques to improve the visibility of liver lesions that are indistinct under conventional US, and to enhance the success rate of percutaneous biopsies.

Methods: In total, 144 patients with liver masses and lesions that were not clearly visible on conventional US from October 2018 to January 2024 were enrolled in this retrospective analysis.

Guanidyl-rich highly branched poly(β-amino ester)s for the delivery of dual CRISPR ribonucleoprotein for efficient large DNA fragment deletion.

Gene editing technologies, particularly clustered regularly interspersed short palindromic repeats (CRISPR) and CRISPR-associated (Cas) proteins, have revolutionized the ability to modify gene sequences in living cells for therapeutic purposes. Delivery of CRISPR/Cas ribonucleoprotein (RNP) is preferred over its DNA and RNA formats in terms of gene editing effectiveness and low risk of off-target events. However, the intracellular delivery of RNP poses significant challenges and necessitates the development of non-viral vectors.

Neural underpinnings of a two-phase memory suppression process in the neural response to self-related and observed perspective views.

Individuals often actively suppress intrusive memories to alleviate the distress they cause and maintain mental well-being. However, those with post-traumatic stress disorder (PTSD) often exhibit difficulties particularly in inhibiting or suppressing negative memories compared to individuals without PTSD. These memories can involve a physical threat either to the individual themselves or to others.

Background: Wilms tumor is one of the most common pediatric kidney cancers with poor prognosis. This study aims to explore the predictive values of lymph nodes (LNs), positive lymph node density (LND) and log odds of positive lymph nodes (LODDS) for the 5-year mortality of children with Wilms tumor.

Methods: The cohort study collected the data of 874 participants with Wilms tumor in the Surveillance, Epidemiology, and End Results (SEER) database.

Rightward brain structural asymmetry in young children with autism.

To understand the neural mechanism of autism spectrum disorder (ASD) and developmental delay/intellectual disability (DD/ID) that can be associated with ASD, it is important to investigate individuals at an early stage with brain, behavioural and also genetic measures, but such research is still lacking. Here, using the cross-sectional sMRI data of 1030 children under 8 years old, we employed developmental normative models to investigate the atypical development of gray matter volume (GMV) asymmetry in individuals with ASD without DD/ID, ASD with DD/ID and individuals with only DD/ID, and their associations with behavioral and clinical measures and transcription profiles. By extracting the individual deviations of patients from the typical controls with normative models, we found a commonly abnormal pattern of GMV asymmetry across all ASD children: more rightward laterality in the inferior parietal lobe and precentral gyrus, and higher individual variability in the temporal pole.
