The experiment was designed to explore the effects and mechanism of Dilong on alleviating cyclophosphamide (CTX)-induced brain injury in mice. Fifty male SPF Kunming mice aged 6-8 weeks were randomly divided into five groups: Group A served as the control group; Group B received intraperitoneal injection of CTX; Groups C, D, and E were administered Dilong at doses of 100, 200, and 400 mg/kg respectively for 14 days after intraperitoneal injection of CTX. Results showed that after modeling, the movement speed of mice significantly decreased (P < 0.

Methods: This multicenter prospective cohort study was conducted across six intensive care units in municipal and above-municipal hospitals in Shaanxi, China, from January 1, 2021 to December 31, 2022. Patients with CRO pneumonia were categorized into the intravenous group (IV polymyxin B alone) and the combination group (AER plus IV polymyxin B).
Dextromethorphan (DXM) is a common ingredient in cough and cold remedies. Despite its widespread presence in aquatic environments, the impact of DXM on fish remains largely unknown. This study evaluated the developmental impairment of zebrafish embryos exposed to DXM from 2 hours post-fertilization (hpf) to 14 days post-fertilization (dpf) at five different exposure concentrations: 0.

Therefore, the SO-treated mice and primary Leydig cell models were established to investigate the effects of SO on the production of testosterone and its specific mechanism. The results demonstrated that SO activated the ERK1/2 signaling pathway, leading to increased key proteins expression of testosterone biosynthesis and elevated testosterone levels.

We designed this methodological survey to evaluate spin reporting in surgical pilot and feasibility trials.
Methods: Medline, Embase, and Cochrane Central Register of Controlled Trials were searched from January 1, 2011, to December 31, 2011, and January 1, 2021, to December 31, 2021.
This study aimed to investigate the molecular mechanisms of reactive oxygen species (ROS)-induced endoplasmic reticulum stress (ERS) in apoptosis and meat tenderization during postmortem aging. Yak longissimus dorsi muscle was incubated with N-acetylcysteine (NAC), 4-phenylbutyric acid (4-PBA) and NAC + 4-PBA, respectively, and stored at 4 °C for 0 h, 12 h, 24 h, 72 h, 120 h and 168 h. The results showed that NAC and 4-PBA treatments significantly reduced ROS content and endoplasmic reticulum stress levels.

With the impact of global climate change, drought events are becoming more frequent, making it critically important to quantitatively evaluate the effects of these events on air pollution. This study uses the augmented synthetic control method and the mediation effect model to quantitatively evaluate the impact effect of the winter-spring drought of 2023 on PM-O compound pollution and its driving factors with Chinese prefecture-level city data. This study indicates that: firstly, compared to non-drought periods, both the monthly averaged and diurnal variations pattern of PM and O significantly increased during drought periods.
View Article and Find Full Text PDFLipid nanoparticles (LNPs) have emerged as pivotal vehicles for messenger RNA (mRNA) delivery to hepatocytes upon systemic administration and to antigen-presenting cells following intramuscular injection. However, achieving systemic mRNA delivery to non-hepatocytes remains challenging without the incorporation of targeting ligands such as antibodies, peptides, or small molecules. Inspired by comb-like polymeric architecture, here we utilized a multiarm-assisted design to construct a library of 270 dendron-like degradable ionizable lipids by altering the structures of amine heads and multiarmed tails for optimal mRNA delivery.

The mid-to-late-stage evolution of the lunar magnetic field is poorly constrained, and thus, the existence of a long-lived lunar dynamo remains controversial. The Chang'e-5 mission returned the heretofore youngest mare basalts from Oceanus Procellarum uniquely positioned at midlatitude.

Traditionally, achieving independent control over all four phase-channels usually involves the introduction of chirality with multilayer or three-dimensional metasurfaces. Here, we present a general chirality-free method that relies on polarization base transformation with a planar minimalist metasurface, effectively decoupling the four Jones matrix phase-channels, thereby unleashing the fundamental boundaries imposed by conventional linear or circular polarization bases.

However, the efficacy of M2-EVs in regulating macrophage polarization and subsequently enhancing osseointegration around titanium (Ti) implants in patients with diabetes mellitus (DM) remains to be elucidated. In this study, Ti implants were coated with polydopamine to facilitate M2-EVs adherence.

Intervertebral disc degeneration (IDD) is a primary contributor to chronic back pain and disability globally, with current therapeutic approaches often proving inadequate due to the complex nature of its pathophysiology. This review assesses the potential of nanoparticle-driven pharmacotherapies to address the intricate challenges presented by IDD. We initially analyze the primary mechanisms driving IDD, with particular emphasis on mitochondrial dysfunction, oxidative stress, and the inflammatory microenvironment, all of which play pivotal roles in disc degeneration.

Previous studies have focused on the organ protection of a single RIPC protocol, and the clinical outcomes remain uncertain. Whether the modified RIPC (mRIPC) protocol performed repeatedly provides cardiopulmonary protection is still uncertain.

In recent years, new oil reservoirs have been discovered and exploited in the ninth member (Chang 9 Member, Ty) of the Upper Triassic Yanchang Formation (Ty) in the Longdong area, Ordos Basin. Some studies have shown that the crude oils of the Chang 9 Member may originate from the Chang 9 source rock in some areas, which may be related to the distribution of the source rock. However, the distribution of the Chang 9 source rock in the Longdong area is still unclear, which hinders further exploration and development of petroleum.
