Metabolomics and WGCNA Analyses Reveal the Underlying Mechanisms of Resistance to in Hazelnut.

Background: Hazelnut (), a significant woody oil tree species in economic forests, faces production constraints due to biotic stresses, with Hazelnut Husk Brown Rot, caused by the pathogenic necrotrophic fungus (), being the most severe. To date, limited information is available regarding the resistance of hazelnuts to . To better understand the mechanisms of resistance to .

Restorative Effects of Short-Chain Fatty Acids on Corneal Homeostasis Disrupted by Antibiotic-Induced Gut Dysbiosis.

The gut microbiota plays a crucial regulatory role in various physiological processes, yet its impact on corneal homeostasis remains insufficiently understood. Here, we investigate the effects of antibiotic-induced gut dysbiosis (AIGD) and germ-free conditions on circadian gene expression, barrier integrity, nerve density, and immune cell activity in the corneas of mice. Through RNA sequencing, we found that both AIGD and germ-free conditions significantly disrupted the overall transcriptomic profile and circadian transcriptomic oscillations in the cornea.

Effects of the types and ages of vegetation restoration on land surface roughness in the Eastern Hobq Desert, Northern China.

Vegetation restoration has an important remodelling effect on near-surface characteristics, and consequent changes in land surface roughness (LSR) are key influences on soil wind erosion processes. However, the effects of vegetation restoration types and ages on LSR and the underlying mechanisms are not fully understood. In this study, the sand-fixing vegetation restoration area of the Hobq Desert was examined in comparison to a bare sand control area.

Activation of the SST-SSTR5 signaling pathway enhances corneal wound healing in diabetic mice.

Corneal wound healing in diabetic patients is usually delayed and accompanied by excessive inflammation. However, the underlying cellular and molecular mechanisms remain poorly understood. Here, we found that somatostatin (SST), an immunosuppressive peptide produced by corneal nerve fibers, was significantly reduced in streptozotocin-induced diabetic mice.

This study discusses four aspects and explores how to promote more scientific and reasonable pre-research. Based on the pre-research practice of medical device standards project, this study puts forward relevant work ideas and suggestions.

HMGA1 sensitizes esophageal squamous cell carcinoma to mTOR inhibitors through the ETS1-FKBP12 axis.

Esophageal carcinoma is amongst the prevalent malignancies worldwide, characterized by unclear molecular classifications and varying clinical outcomes. The PI3K/AKT/mTOR signaling, one of the frequently perturbed dysregulated pathways in human malignancies, has instigated the development of various inhibitory agents targeting this pathway, but many ESCC patients exhibit intrinsic or adaptive resistance to these inhibitors. Here, we aim to explore the reasons for the insensitivity of ESCC patients to mTOR inhibitors.

O-GlcNAc of STING mediates antiviral innate immunity.

Background: O-GlcNAcylation modification affects multiple physiological and pathophysiolocal functions of cells. Altered O-GlcNAcylation was reported to participate in antivirus response. Stimulator of interferon genes (STING) is an adaptor mediating DNA virus-induced innate immune response.

TRPV1 sensory nerves suppress conjunctival inflammation via SST-SSTR5 signaling in murine allergic conjunctivitis.

Allergic conjunctivitis (AC), an allergen-induced ocular inflammatory disease, primarily involves mast cells (MCs) and eosinophils. The role of neuroimmune mechanisms in AC, however, remains to be elucidated. We investigated the effects of transient receptor potential vanilloid 1 (TRPV1)-positive sensory nerve ablation (using resiniferatoxin) and TRPV1 blockade (using Acetamide, N-[4-[[6-[4-(trifluoromethyl)phenyl]-4-pyrimidinyl]oxy]-2-benzothiazolyl] (AMG-517)) on ovalbumin-induced conjunctival allergic inflammation in mice.

Exploring Immune Cell Diversity in the Lacrimal Glands of Healthy Mice: A Single-Cell RNA-Sequencing Atlas.

The lacrimal gland is responsible for maintaining the health of the ocular surface through the production of tears. However, our understanding of the immune system within the lacrimal gland is currently limited. Therefore, in this study, we utilized single-cell RNA sequencing and bioinformatic analysis to identify and analyze immune cells and molecules present in the lacrimal glands of normal mice.

Development and management of gastrointestinal symptoms in long-term COVID-19.

Background: Emerging evidence reveals that SARS-CoV-2 possesses the capability to disrupt the gastrointestinal (GI) homeostasis, resulting in the long-term symptoms such as loss of appetite, diarrhea, gastroesophageal reflux, and nausea. In the current review, we summarized recent reports regarding the long-term effects of COVID-19 (long COVID) on the gastrointestine.

Objective: To provide a narrative review of abundant clinical evidence regarding the development and management of long-term GI symptoms in COVID-19 patients.

Deep learning driven colorectal lesion detection in gastrointestinal endoscopic and pathological imaging.

Colorectal cancer has the second highest incidence of malignant tumors and is the fourth leading cause of cancer deaths in China. Early diagnosis and treatment of colorectal cancer will lead to an improvement in the 5-year survival rate, which will reduce medical costs. The current diagnostic methods for early colorectal cancer include excreta, blood, endoscopy, and computer-aided endoscopy.

Value of systemic PET/CT in the diagnosis and differential diagnosis of aplastic anemia.

The aim of the present study was to investigate the value of systemic [F]fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT) in the diagnosis and differential diagnosis of aplastic anemia (AA). Systemic PET/CT imaging results of 24 patients diagnosed with AA in The First Affiliated Hospital of Sun Yat-Sen University between May 2011 and August 2014 were retrospectively analyzed and compared with results from healthy individuals and patients with acute leukemia (AL) or myelodysplastic syndrome (MDS) in the same period to summarize the PET/CT characteristics of patients with AA. Systemic PET/CT manifestations of the 24 patients with AA were classified into three types: Normal bone marrow metabolism, hypometabolism and hypometabolism complicated by focal hyperproliferation.

Gambogic Acid Induces Cell Apoptosis and Inhibits MAPK Pathway in PTEN/p53 Prostate Cancer Cells In Vitro and Ex Vivo.

Objective: To investigate the effect of gambogic acid (GA) on the growth and cell death of castrate resistant prostate cancer (PC) with phosphate and tension homology (PTEN) and p53 genes deleted in vitro and ex vivo, and elucidate the underlying possible molecular mechanisms.

Topological Structures and Membrane Nanostructures of Erythrocytes after Splenectomy in Hereditary Spherocytosis Patients via Atomic Force Microscopy.

Hereditary spherocytosis is an inherited red blood cell membrane disorder resulting from mutations of genes encoding erythrocyte membrane and cytoskeletal proteins. Few equipments can observe the structural characteristics of hereditary spherocytosis directly expect for atomic force microscopy In our study, we proved atomic force microscopy is a powerful and sensitive instrument to describe the characteristics of hereditary spherocytosis. Erythrocytes from hereditary spherocytosis patients were small spheroidal, lacking a well-organized lattice on the cell membrane, with smaller cell surface particles and had reduced valley to peak distance and average cell membrane roughness vs.
