The Preventive Effect of Ulinastatin on Blood-Brain Barrier Dysfunction in Rats with Postoperative Cognitive Dysfunction After General Anaesthesia with Isoflurane.

This study evaluated the effect of ulinastatin on blood-brain barrier (BBB) dysfunction in rats with postoperative cognitive dysfunction (POCD) following general anaesthesia with isoflurane. Specifically, we examined BBB permeability and the expression of tissue inhibitor of matrix metalloproteinase-1 (TIMP-1). Rats in the ulinastatin group received the drug intraperitoneally (50,000 U/mL), while controls received normal saline (1 mL) administered before general anaesthesia.

Discovery and Prediction Study of the Dominant Pharmacological Action Organ of Debeaux Using Multiple Bioinformatic Analyses.

Herbs, such as Debeaux (ACD), have long been used as therapies, but it is difficult to identify which organs of the human body are affected by the various compounds. In this study, we predicted the organ where the drug predominantly acts using bioinformatics and verified it using transcriptomics. We constructed a computer-aided brain system network (BSN) and intestinal system network (ISN).

Comparative Analysis of Olfactory and Gustatory Function of Patients With COVID-19 Olfactory Dysfunction and Non-COVID-19 Postinfectious Olfactory Dysfunction.

Background: Coronavirus disease 2019 (COVID-19) is known to have a high incidence of loss of smell and taste. However, studies in the early stages of the COVID-19 pandemic have evaluated these symptoms using subjective surveys and simple olfactory tests only. Hence, we compared the olfactory and gustatory characteristics of patient groups with COVID-19 olfactory dysfunction (C19OD) and non-COVID-19 postinfectious olfactory dysfunction (PIOD) using an objective olfactory test and evaluated the significance of olfactory training in both patient groups.

CD103 Cells and Chemokine Receptor Expression in Breast Cancer.

Mucosal environments harbour lymphocytes, which express several adhesion molecules, including intestinal homing receptors and integrin αE/β7 (CD103). CD103 binds E-cadherin, an integrin receptor expressed in intestinal endothelial cells. Its expression not only enables homing or retention of T lymphocytes at these sites but is also associated with increased T lymphocyte activation.

Multi-omics data of gastric cancer cell lines.

Objectives: Gastric cancer (GC) is the fourth most common cancer worldwide, with the highest incidence and mortality regardless of sex. Despite technological advances in diagnosing and treating gastric cancer, GC still has high incidence and mortality rates. Therefore, continuous research is needed to overcome GC.

The Effect of Ketamine on Endoplasmic Reticulum Stress in Rats with Neuropathic Pain.

This study aimed to investigate the effects of ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, on endoplasmic reticulum (ER) stress in rats with neuropathic pain (NP). NP was induced in rats through ligation and transection of the sciatic nerve. After confirmation of NP, the animals were randomly divided into ketamine and control groups.

Exogenous Lipoxin A4 attenuates IL4-induced Mucin Expression in Human Airway Epithelial Cells.

The proinflammatory cytokine interleukin-4 (IL-4) induces mucus hypersecretion by human airway epithelial cells and the MAP kinase signalling pathway may be important in terms of IL-4-induced MUC5AC gene expression. Lipoxin A (LXA) is an arachidonic acid-derived mediator that promotes inflammation by binding to the anti-inflammatory receptors (ALXs) or the formyl-peptide receptor like-1 (FPRL1) protein expressed by airway epithelial cells. Here, we explore the effects of LXA4 on IL-4-induced mucin gene expression in, and secretion from, human airway epithelial cells.

Extradural Spinal Lymphoplasmacyte-Rich Meningioma in the Thoracic Spine: A Case Report and Literature Review.

Most spinal meningiomas have an intradural or partly extradural location. The meningothelial origin is the most common pathologic type of spinal meningioma. Pure extradural spinal meningiomas are not common, and lymphoplasmacyte-rich meningioma (LPRM) is very rare.

Effects of general anaesthesia with an inhalational anaesthetic agent on the expression of exosomes in rats.

We hypothesized that the expression of exosomes under general anaesthesia with an inhalational anaesthetic agent would be changed. The study was designed to confirm the effect of general anesthesia with an inhalational anaesthetic agent on the expression of exosomes in rats. After intraperitoneal administration for the mixture of ketamine and xylazine, tracheal intubation was performed.

Intraosseous ganglion cyst mimicking chondrosarcoma on MRI: a case report.

Background: The intraosseous ganglia is a benign cyst, rarely locate in the olecranon process. As intraosseous ganglia can mimic malignant bone tumor, computed tomography (CT) is important for diagnosis even when magnetic resonance imaging (MRI) suggests malignant bone tumor, such as chondrosarcoma.

Case Presentation: In this paper, we report a 42-year-old woman with intraosseous ganglia in the olecranon process of the ulna.

The Preventive Effect of the Phenotype of Tumour-Associated Macrophages, Regulated by CD39, on Colon Cancer in Mice.

Background: This study was designed to investigate the effect of cluster differentiation (CD)39 and CD73 inhibitors on the expresion of tumour-associated macrophages (TAMs), M1- versus M2-tumour phenotypes in mice with colon cancer.

Methods: An in vivo study of co-culture with colon cancer cells and immune cells from the bone marrow (BM) of mice was performed. After the confirmation of the effect of polyoxotungstate (POM-1) as an inhibitor of CD39 on TAMs, the mice were randomly divided into a control group without POM-1 and a study group with POM-1, respectively, after subcutaneous injection of CT26 cells.

MicroRNA Expression in Extracellular Vesicles from Nasal Lavage Fluid in Chronic Rhinosinusitis.

Extracellular vesicles (EVs) are nanovesicles of endocytic origin released by cells and found in human bodily fluids. EVs contain both mRNA and microRNA (miRNA), which can be shuttled between cells, indicating their role in cell communication. This study investigated whether nasal secretions contain EVs and whether these EVs contain RNA.

Improvement of the therapeutic capacity of insulin-producing cells trans-differentiated from human liver cells using engineered cell sheet.

Background: Although pancreatic islet transplantation therapy is ideal for diabetes patients, several hurdles have prevented it from becoming a standard treatment, including donor shortage and low engraftment efficacy. In this study, we prepared insulin-producing cells trans-differentiated from adult human liver cells as a new islet source. Also, cell sheet formation could improve differentiation efficiency and graft survival.

The effects of endoplasmic reticulum stress on the expression of exosomes in ventilator-induced lung injury.

Background: We hypothesized that endoplasmic reticulum stress (ER) would be associated with exosomes in ventilator-induced lung injury (VILI), and that inhibition of ER stress would be linked to less occurrence of VILI or less damage in VILI.

Methods: Mice were randomly allocated to a control group and an Inhibitor group. Normal saline (0.

Methylation of the CDX2 promoter in Helicobacter pylori-infected gastric mucosa increases with age and its rapid demethylation in gastric tumors is associated with upregulated gene expression.

Pathological changes in the epigenetic landscape of chromatin are hallmarks of cancer. The caudal-type homeobox gene CDX2 is not expressed in normal gastric epithelia but rather in adult intestinal epithelia, and it is overexpressed in intestinal metaplasia (IM). However, it remains unclear how CDX2 transcription is suppressed in normal gastric epithelial cells and overexpressed in IM.

Immune response in fluid therapy with crystalloids of different ratios or colloid for rats in haemorrhagic shock.

This study investigated the association between different ratios of balanced salt based-crystalloid (PLASMA SOLUTION-A [CJ HealthCare, Seoul, Korea]) (the ratios of crystalloid for blood loss, 1:1, 1:2 and 1:3) or balanced salt-based colloid (VOLULYTE 6% [Fresenius Kabi, Germany]) (the ratio of colloid for blood loss, 1:1) to restore blood loss and immune response in rats with haemorrhagic shock. About 50% of total estimated blood volume was removed after anaesthesia. The fluid was administered for resuscitation after exsanguination, according to the type of fluid and the ratios of exsanguinated volume and fluid volume for resuscitation.

The effect of repetitive exposure to intravenous anesthetic agents on the immunity in mice.

: This study was designed to assess the effect of repetitive exposure to intravenous anesthetic agents on the immunity in mice. : The mice were divided into six groups: three intravenous anesthetic agents groups (dexmedetomidine, midazolam and propofol groups), and three corresponding control groups (C, C, and C groups). The intravenous injections were administered once per day for 5 days.

ONECUT2 upregulation is associated with CpG hypomethylation at promoter-proximal DNA in gastric cancer and triggers ACSL5.

Many studies have focused on global hypomethylation or hypermethylation of tumor suppressor genes, but less is known about the impact of promoter hypomethylation of oncogenes. We previously showed that promoter methylation may gradually increase or decrease during the transition from gastric mucosa (GM) to intestinal metaplasia (IM) to gastric cancer (GC). In our study, we focused on regional CpG hypomethylation of the promoter-proximal DNA of the transcription factor ONECUT2 (OC2) in IM and GC cells.

PRMT1 Is Required for the Maintenance of Mature β-Cell Identity.

Loss of functional β-cell mass is an essential feature of type 2 diabetes, and maintaining mature β-cell identity is important for preserving a functional β-cell mass. However, it is unclear how β-cells achieve and maintain their mature identity. Here we demonstrate a novel function of protein arginine methyltransferase 1 (PRMT1) in maintaining mature β-cell identity.
