[Effects of Different Types of Plastic Film Mulching on Soil Quality, Root Growth, and Yield].

Aiming to address the problem of soil environmental pollution caused by the large-scale use of plastic film in agricultural production in China, field experiments were carried out by applying degradable plastic film. Pumpkin was used as the research material to explore the effects of black common plastic film (CK), white degradation plastic film (WDF), black degradation plastic film (BDF), and black CO-based degradable plastic film (C-DF) on soil physicochemical properties, root growth and yield, and soil quality. The results showed that the soil water content and temperature of the three degradable plastic films were lower than those of ordinary plastic films to different degrees; there was no significant difference in soil organic matter content among the treatments.

A novel prognostic signature of cuproptosis-related genes and the prognostic value of FDX1 in gliomas.

Gliomas are the most common malignant tumors of the central nervous system, with extremely bad prognoses. Cuproptosis is a novel form of regulated cell death. The impact of cuproptosis-related genes on glioma development has not been reported.

[Serological Characteristics and Molecular Biological Mechanism of AEL.02 Subtype].

Objective: To explore the serological characteristics and molecular biological mechanism of an a subtype specimen.

Methods: The ABO blood typing was identified by routine blood group serological and absorption/elution methods; PCR-SBT method for ABO genotyping: 7 exons of ABO gene were amplified by PCR, the amplified products were purified, and then sequencing primers were designed and the amplified products were sequenced directly for analysis; 3D molecular model was constructed and the difference of free energy (ΔΔG) was used to predict the GTA mutant stability.

Results: A antigen was not detected on erythrocytes through absorption and elution tests, which was not consistent with the serological characteristics of a, and the serological typing results were ambiguous.

Relationship Between Serum Fibrinogen Level and Depressive Symptoms in an Adult Population with Spinal Cord Injury: A Cross-Sectional Study.

We aimed to investigate the association of inflammatory markers with depression in middle-aged and elderly SCI patients.

Erythromycin inhibits cigarette smoke-induced inflammation through regulating the PPARγ/NF-κB signaling pathway in macrophages.

Chronic obstructive pulmonary disease is characterized by chronic inflammation of the airway and lungs. Accumulating evidence has suggested that erythromycin (EM) plays a protective role against cigarette smoke-induced oxidative stress and the inflammatory response. However, the underlying mechanisms remain relatively unclear.

The Notch Signaling Pathway Regulates Differentiation of NG2 Cells into Oligodendrocytes in Demyelinating Diseases.

NG2 cells are highly proliferative glial cells that can self-renew or differentiate into oligodendrocytes, promoting remyelination. Following demyelination, the proliferative and differentiation potentials of NG2 cells increase rapidly, enhancing their differentiation into functional myelinating cells. Levels of the transcription factors Olig1 and Olig2 increase during the differentiation of NG2 cells and play important roles in the development and repair of oligodendrocytes.

Animal Models of Cerebral Changes Secondary to Spinal Cord Injury.

Spinal cord injuries (SCIs) are difficult to treat. The first animal SCI model (featuring the dropping of a weight) was established by Allen in 1911, and other animal models have been developed since then. Most animal studies have focused only on the molecular features of SCIs, which remain disputed.

Erythromycin reverses cigarette smoke extract-induced corticosteroid insensitivity by inhibition of the JNK/c-Jun pathway.

Corticosteroid insensitivity is a feature of airway inflammation in chronic obstructive pulmonary disease (COPD). Erythromycin exhibits anti-inflammatory activity in COPD, but the concrete mechanism is still unclear. This study aimed to investigate the effects of erythromycin on corticosteroid sensitivity in peripheral blood mononuclear cells (PBMCs) and U937 cells (a human monocytic cell line).

Expression of GR-α and HDAC2 in steroid-Sensitive and steroid-Insensitive interstitial lung disease.

Background: Corticosteroid is one of the main treatments for interstitial lung disease (ILD). Cryptogenic-organizing pneumonia (COP) is sensitive to corticosteroid therapy, whereas idiopathic pulmonary fibrosis (IPF) is not. Glucocorticoid receptor-α (GR-α) and histone deacetylase 2 (HDAC2) play critical roles in the sensitivity to corticosteroid therapy; however, it is unclear whether HDAC2 and/or GR-α are expressed in the lung tissues of patients with COP and/or IPF.

Erythromycin suppresses neutrophil extracellular traps in smoking-related chronic pulmonary inflammation.

Neutrophil extracellular traps (NETs) may play a critical role in smoking-related chronic airway inflammation. However, the mechanism by which NETs induced by cigarette smoke initiate the adaptive immunity in chronic obstructive pulmonary disease (COPD) is not fully understood. In this study, we explored the effects of NETs induced by cigarette smoke on the myeloid dendritic cells (mDCs) and Th1 and Th17 cells.

Objectives: The present study was designed to examine the effects of erythromycin (EM) on the SIRT1-NF-κB axis and NF-κB-dependent proinflammatory cytokines.

Role of Vascular Endothelial-Cadherin and p120-Catenin in the Formation of Experimental Intracranial Aneurysm in Animals.

Background: Dysfunction of endothelial cells (ECs) constitutes a critical factor in the formation of intracranial aneurysms (IAs). However, little is known about the response of ECs to hemodynamic insults and its contribution to IA formation.

Methods: IAs models were constructed in both adult female New Zealand white rabbits and male Sprague-Dawley rats.

Knockdown of P120 catenin aggravates endothelial injury under an impinging flow by inducing breakdown of adherens junctions.

At present, the mechanisms underlying intracranial aneurysm (IA) development remain unclear; however, hemodynamics is considered a crucial factor in the induction of IA. To elucidate the association between hemodynamics and endothelial cell (EC) functions, a modified T chamber system was designed to simulate the adjustable hemodynamic conditions of an artery bifurcation. Normal human umbilical vein ECs (HUVECs) and HUVECs with P120 catenin (P120ctn) knockdown were cultured on coverslips and placed in the chamber.

Zinc alpha2 glycoprotein protects against obesity-induced hepatic steatosis.

Background/aim: Nonalcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis, impaired insulin sensitivity, and chronic low-grade inflammation. Our previous studies indicated that zinc alpha2 glycoprotein (ZAG) alleviates palmitate (PA)-induced intracellular lipid accumulation in hepatocytes. This study is to further characterize the roles of ZAG on the development of hepatic steatosis, insulin resistance (IR), and inflammation.
