NSUN2-Mediated RNA 5-Methylcytosine Modification of PTEN Regulates Cognitive Impairments of Mice with Sleep Deprivation and Autophagy Through PI3K/AKT Signaling.

Sleep deprivation (SD) impairs learning and memory. Investigating the role of epigenetic modifications, such as 5-methylcytosine (mC), in SD is crucial. This study established an SD mouse model and assessed the mRNA levels of mC-related genes in brain tissue to identify potential candidates.

Natural background levels and driving factors of aluminum in shallow groundwater of an urbanized delta: Insight from eliminating anthropogenic-impacted groundwaters.

Knowledge on natural background levels (NBLs) of aluminum (Al) in groundwater can accurately assess groundwater Al contamination at a regional scale. However, it has received little attention. This study used a combination of preselection and statistic methods consisting of the oxidation capacity and the boxplot iteration methods to evaluate the NBL of shallow groundwater Al in four groundwater units of the Pearl River Delta (PRD) via eliminating anthropogenic-impacted groundwaters and to discuss driving factors controlling high NBLs of Al in groundwater in this area.

Block Copolymer Nanomicelle-Encapsulated Curcumin Attenuates Cerebral Ischemia Injury and Affects Stem Cell Marker Expression by Inhibiting lncRNA GAS5.

Stroke has become the most common cause of death among residents in China, among which ischemic stroke accounts for the vast majority reaching 70% to 80%. It is of great importance to actively investigate the protective mechanism of cerebral ischemia injury after IS (ischemic stroke). We constructed cerebral ischemia injury models MACO rat and (oxygen-glucose deprivation cell model) and set up different interference groups.

Effects of Vestibular Damage on the Sleep and Expression Level of Orexin in the Hypothalamus of Rats and Its Correlation with Autophagy and Akt Tumor Signal Pathway.

The aim of this study was to investigate the effect of vestibular disruption on autophagy-related proteins and the tumour-associated pathway P13K/Akt in rat sleep and its hypothalamus tissue and to examine whether catechins trigger tumour autophagy. Healthy adult male rats were randomly selected and divided into the vestibular damage group, the sham operation group, and the control group, with 8 rats in each group. A vestibular damage model was established through penetrating the tympanic membrane of the external auditory canal by injecting sodium p-aminophenylarsonate.

Down-Regulated microRNA-192-5p Protects Against Hypoxic-Ischemic Brain Damage via Regulation of YAP1-Mediated Hippo Signaling Pathway.

Hypoxic-ischemic brain damage (HIBD) is a familiar neurological disorder. Emerging reports manifest that microRNAs (miRs) are related to the progression of HIBD. The goal of this study is to explore the mechanism of miR-192-5p in HIBD via regulation of Yes-associated protein 1 (YAP1)-mediated Hippo signaling pathway.

Triblock Copolymer Nanomicelles Loaded with Curcumin Attenuates Inflammation via Inhibiting the NF-κB Pathway in the Rat Model of Cerebral Ischemia.

Aim: Cerebral ischemic injury is one of the debilitating diseases showing that inflammation plays an important role in worsening ischemic damage. Therefore, studying the effects of some potential anti-inflammatory compounds can be very important in the treatment of cerebral ischemic injury.

Methods: This study investigated anti-inflammatory effects of triblock copolymer nanomicelles loaded with curcumin (abbreviated as NC) in the brain of rats following transient cerebral ischemia/reperfusion (I/R) injury in stroke.

A noninvasive indicator for the diagnosis of early hepatitis B virus-related liver fibrosis.

Background And Aims: Liver stiffness measurement (LSM) detected by FibroScan, combined with biochemical indexes, has shown potential values for assessment of liver fibrosis pathological degrees. Here we aimed to investigate a noninvasive method for hepatitis B virus-related liver fibrosis.

Patients And Methods: In all, 307 patients who underwent liver biopsy and LSM measurement were included.

Potentials of the elevated circulating miR-185 level as a biomarker for early diagnosis of HBV-related liver fibrosis.

Early diagnosis of liver fibrosis is critical for early intervention and prognosis of various chronic liver diseases. Conventional repeated histological assessment is impractical due to the associated invasiveness. In the current study, we evaluated circulating miR-185 as a potential biomarker to predict initiation and progression of liver fibrosis.

MicroRNA-34a Promotes Hepatic Stellate Cell Activation via Targeting ACSL1.

Background: The incidence of liver fibrosis remains high due to the lack of effective therapies. Our previous work found that microRNA (miR)-34a expression was increased, while acy1-CoA synthetase long-chain family member1 (ACSL1) was decreased, in a dimethylnitrosamine (DNS)-induced hepatic fibrosis rat model. We hypothesized that miR-34a may play a role in the process of hepatic fibrosis by targeting ACSL1.
