Background: Sirolimus is increasingly utilized in treating diseases associated with mTOR pathway overactivation. Despite its potential, the lack of evidence regarding its long-term safety across all age groups, particularly in pediatric patients, has limited its further application. This study aims to assess the long-term safety of sirolimus, with a specific focus on its impact on growth patterns in pediatric patients.

Background: This study aimed to improve the stability and utilization of sulforaphene (SFE) and to enhance the intestinal stability and pH-sensitive release of SFE in the gastrointestinal tract. To achieve this objective, calcium chloride (CaCl) was used as a crosslinking agent to fabricate novel SFE-loaded gellan gum (GG)-ε-polylysine (ε-PL) pH-sensitive hydrogel microspheres by using the ionic crosslinking technique.

Results: The molecular docking results of GG, ε-PL, and SFE were good and occurred in the natural state.

Background: Previous neuroimaging and pathological studies have found myelin-related abnormalities in bipolar disorder (BD), which prompted the use of magnetic resonance (MR) imaging technology sensitive to neuropathological changes to explore its neuropathological basis. We holistically investigated alterations in myelin within BD patients by inhomogeneous magnetization transfer (ihMT), which is sensitive and specific to myelin content.

Methods: Thirty-one BD and 42 healthy controls (HC) were involved.

Fetal alcohol syndrome (FAS) is a neurological disease caused by excessive drinking during pregnancy and characterized by congenital abnormalities in the structure and function of the fetal brain. This study was proposed to provide new insights into the pathogenesis of FAS by revealing the possible mechanisms of alcohol-induced astrocyte injury. First, a chronic alcohol exposure model of astrocytes was established, and the formation disorder was found in astrocyte processes where tubulin-binding cofactor B (TBCB) was decreased or lost, accompanied by disorganized microtubules (MT).

Foetal alcohol spectrum disorders (FASDs) are a spectrum of neurological disorders whose neurological symptoms, besides the neuronal damage caused by alcohol, may also be associated with neuroglial damage. Tubulin-binding cofactor B (TBCB) may be involved in the pathogenesis of FASD. To understand the mechanism and provide new insights into the pathogenesis of FASD, acute foetal alcohol exposure model on astrocytes was established and the interference experiments were carried out.

Sequencing costs currently prohibit the application of single-cell mRNA-seq to many biological and clinical analyses. Targeted single-cell mRNA-sequencing reduces sequencing costs by profiling reduced gene sets that capture biological information with a minimal number of genes. Here we introduce an active learning method that identifies minimal but highly informative gene sets that enable the identification of cell types, physiological states and genetic perturbations in single-cell data using a small number of genes.

In this study, the impact of resveratrol (RES) on co-oxidation of lipid and protein in a fish oil-fortified whey protein isolate (WPI) emulsion was investigated. Oil-in-water (O/W) emulsions containing 1% fish oil, 6 mg/mL of WPI and RES (0.08 ~ 2 mM) were oxidatively stressed using a Fenton system at 25 °C for 24 h.

Duchenne muscular dystrophy (DMD) is a fatal X-linked genetic disease of the neuromuscular system and is the most serious type of muscular dystrophy in humans. The disease is characterized by progressive muscular atrophy and a poor prognosis. The incidence rate is 1/3500, and symptoms appear at age of 5 years-old.

Purpose: This study aimed to analyze the therapeutic effect of sirolimus on seizures in pediatric patients with tuberous sclerosis.

Methods: We first compared the efficacy of controlling seizures in all patients after they had taken sirolimus for one year, and then we performed a subgroup analysis based on whether the administered antiepileptic drugs were changed to determine whether the efficacy was associated with changes of antiepileptic drugs.

Results: A total of 91 eligible children were enrolled.

Impacts of lipid oxidation product malondialdehyde (MDA) on the properties of whey protein isolate (WPI) were investigated in this study. The incorporation of MDA into WPI promoted the formation of protein carbonyls, with the significant loss of protein sulfhydryls, impaired intrinsic fluorescence, and increased protein surface hydrophobicity. The visualized band profiles revealed by gel electrophoresis and immunoblotting suggested that WPI's main components β-lactoglobulin and α-lactalbumin were the targets of MDA, and the derivatives of MDA were involved in protein cross-linking and aggregation at higher molecular weights.

Asthma is a chronic inflammatory disorder of airways that involves in many cells and factors. This study aimed to screen critical genes and miRNAs involved in childhood atopic asthma. DNA methylation and gene expression data (access numbers GSE65163 and GSE65204) were downloaded from Gene Expression Omnibus (GEO) database, which included 72 atopic asthmatic subject samples and 69 healthy samples.

Chemotherapy resistance represents a major issue associated with gastric cancer (GC) treatment, and arises through multiple mechanisms, including modulation of the cell-cycle check point. Several ubiquitin kinases, including RING finger protein 138 (RNF138), have been reported to mediate the G2/M phase arrest. In this study, we investigated the role of RNF138 in the development of cisplatin resistance of two GC cell lines.

Autism spectrum disorder (ASD) is a genetically heterogeneous neurodevelopmental disorder characterized by impairments in social interaction and communication, and by restricted and repetitive behaviors. The genetic architecture of ASD has been elucidated, including chromosomal rearrangements, de novo or inherited rare variants, and copy number variants. However, the genetic mechanism of Chinese families with ASD children is explored rarely.

In this paper, MnO nanoboxes coated with poly(3,4-ethylenedioxythiophene) film (denoted as MnO@PEDOT) are investigated as an anode material in lithium-ion batteries. The MnO nanoboxes are developed through the surface chemical oxidation decomposition of MnCO cubes and the subsequent removal of their remaining cores. PEDOT is coated on the surface of MnO nanoboxes via in situ polymerization of 3,4-ethylenedioxythiophene.
