Central Nervous System-Targeted Gene Therapy for the Treatment of Neurocognitive Deficits in Mucopolysaccharidosis Type II Mice.

Mucopolysaccharidosis type II (MPS II) is an X-linked lysosomal storage disorder caused by pathogenic variants in the gene encoding iduronate-2-sulfatase (IDS), which hydrolyzes sulfate groups in dermatan sulfate and heparan sulfate. The current treatment for MPS II includes enzyme replacement therapy and hematopoietic stem cell transplantation (HSCT). Both therapies have shown limited penetration through the blood-brain barrier.

A Wireless Health Monitoring System Accomplishing Bimodal Decoupling Based on an "IS"-Shaped Multifunctional Conductive Hydrogel.

Flexible wearable sensors with bimodal functionality offer substantial value for human health monitoring, as relying on a single indicator is insufficient for capturing comprehensive physiological information. However, bimodal sensors face multiple challenges in practical applications, including mutual interference between various modalities, and integration of excellent mechanical properties, interfacial adhesion, environmental adaptability and biocompatibility. Herein, the multifunctional hydrogel, synthesized through radical grafting and supramolecular self-crosslinking reactions, exhibits excellent thermal sensitivity (TCR = -1.

GATD3A-deficiency-induced mitochondrial dysfunction facilitates senescence of fibroblast-like synoviocytes and osteoarthritis progression.

Accumulating evidence indicates that cellular senescence is closely associated with osteoarthritis. However, there is limited research on the mechanisms underlying fibroblast-like synoviocyte senescence and its impact on osteoarthritis progression. Here, we elucidate a positive correlation between fibroblast-like synoviocyte senescence and osteoarthritis progression and reveal that GATD3A deficiency induces fibroblast-like synoviocyte senescence.

Effect of Intravenous Lidocaine Infusion on Propofol Dose and Perioperative Pain During Moderate Sedation-Analgesia for Hysteroscopy: A Randomized Controlled Trial.

Purpose: In China, the majority of hysteroscopic procedures require moderate sedation and analgesia. The efficacy of intravenous lidocaine in reducing the need for sedatives and alleviating perioperative pain during hysteroscopy remains equivocal. This study aims to determine whether the intravenous administration of lidocaine can reduce the required dose of propofol and enhance perioperative pain management.

Green manure plants enhance atrazine degradation in agriculture soil through modulating rhizosphere microbial communities.

The widespread use of atrazine in agriculture threatens soil health and the safety of agricultural products. In this study, the removal and mechanism of green manure plants (GMPs) hairy vetch (Vicia villosa Roth, VV) and ryegrass (Lolium perenne L., LP) to atrazine were investigated.

Theoretical insights on potential-dependent oxidation behaviors and antioxidant strategies of MXenes.

Significant efforts have been devoted to investigating the oxidation of MXenes in various environments. However, the underlying mechanism of MXene oxidation and its dependence on the electrode potential remain poorly understood. Here we show the oxidation behavior of MXenes under the working conditions of electrochemical processes in terms of kinetics and thermodynamics by using constant-potential ab initio simulations.

A Rapid Quantitative Assessment Method for Liver Damage Effects of Compounds Based on Zebrafish Liver Partition Area Ratio.

Total liver area is a traditional indicator in evaluating compound liver damage with zebrafish models. However, in some experiments, compounds changed zebrafish liver morphology but total liver area showed no significant difference, indicating it is inaccurate for evaluating compound effects on zebrafish liver damage. Therefore, in this study, transgenic zebrafish Tg(l-fabp:EGFP) labeled with liver cells using green fluorescent protein was used to evaluate compound effects on liver by the liver partition area ratio.

Effect of endoscopic submucosal dissection on gastrointestinal function and nutritional status in patients with early gastric cancer.

Background: Gastric cancer (GC) endangers the survival and prognosis of patients worldwide. Improving the prognosis of patients with early GC (EGC) is crucial to prolong their survival time.

Aim: To analyze the effects of endoscopic submucosal dissection (ESD) on gastrointestinal function and nutritional status in patients with EGC.

Fucoidan-derived carbon dots as nanopenetrants of blood-brain barrier for Parkinson's disease treatment.

Parkinson's Disease (PD) stands as a prevalent neurodegenerative disorder. However, current pharmacotherapies for PD face challenges due to inadequate penetration through the blood-brain barrier (BBB), posing limitations on their therapeutic efficacy. Considering the potential of negatively charged carbon dots (CDs) in retaining functional groups from precursor molecules and vertically crossing the BBB, this study focuses on the utilization of fucoidan (FD), a promising pharmaceutical candidate with neuroprotective effects on dopamine-active neurons, for the development of negatively charged CDs through a one-step hydrothermal method, aiming to achieve efficient BBB penetration for PD treatment.

The mammary gland undergoes functional, developmental, and structural changes that are essential for lactation and reproductive processes. An overview of such unique tissue can offer clearer insights into mammary development and tumorigenesis. Compared to traditional methods, mouse mammary gland whole mount is a pivotal technique that provides three-dimensional structural perspectives on gland morphology and developmental stages, offering an inexpensive and accessible approach.

The Biomimetic Electrical Stimulation System Inducing Osteogenic Differentiations of BMSCs.

Electrical stimulation has been used clinically as an adjunct therapy to accelerate the healing of bone defects, and its mechanism requires further investigations. The complexity of the physiological microenvironment makes it challenging to study the effect of electrical signal on cells alone. Therefore, an artificial system mimicking cell microenvironment was developed to address this issue.

Cordyceps polysaccharide improves polycystic ovary syndrome by inhibiting gut-derived LPS/TLR4 pathway to attenuates insulin resistance.

Thermosensitive and injectable chitosan-based hydrogel embedding umbilical cord mesenchymal stem cells for β-cell repairing in type 2 diabetes mellitus.

A thermosensitive and injectable hydrogel composed of chitosan (CS), chitosan biguanide hydrochloride (CSG) and collagen (CO) could embed umbilical cord mesenchymal stem cells (UC-MSCs), then was applied for the type 2 diabetes mellitus (T2DM) treatment in vivo. UC-MSCs could adhere well on CS/CSG/CO hydrogel surface and cell division could be clearly observed. Especially, UC-MSCs maintained alive till they grew in CS/CSG/CO hydrogel for 8 days, while the amount of UC-MSCs was limited due to the steric hindrance in hydrogel.
