Identifying the Potential of miRNAs in -Derived Exosome-Like Nanoparticles Against Respiratory RNA Viruses.

Introduction: Pathogenic respiratory RNA viruses, including influenza A virus (IAV), respiratory syncytial virus (RSV), and SARS-CoV-2, are major causes of causes of acute respiratory infection globally. Plant-derived exosome-like nanoparticles containing miRNAs have shown substantial cross-kingdom regulatory effects on both viral and human transcripts. (), a traditional Chinese medicine frequently used to treat respiratory diseases.

Enteric glial cells exert neuroprotection from hyperglycemia-induced damage via Akt/GSK3β pathway.

Objective: Enteric glial cells (EGCs) can activate multiple pathways to inhibit the deleterious effects of acute and chronic insults. Our aim was to test the effect of EGCs on hyperglycemia-induced neuron damage and its underlying intracellular mechanisms.

Methods: A coculture model composed of EGCs and neuroblastoma cells (SH-SY5Y) was established to examine glial-mediated neuroprotection under high glucose conditions.

Cerebral ischemia-reperfusion causes a down regulation of HCN1 expression via enhancing the nuclear NRSF-HDAC4 gathering that contributes to neuron damage.

Cerebral ischemia-reperfusion (I/R) can trigger neuronal death through several biologically plausible pathways, but its underlying neurobiological mechanisms remain unclear. In this study, we tested whether hyperpolarization-activated cyclic nucleotide-gated channel 1 (HCN1) is altered in I/R that contributes to neuron damage and further clarified the mechanisms underlying this process. Cerebral I/R injury was induced by middle cerebral artery occlusion (MCAO) surgery followed by reperfusion in rats or simulated by oxygen-glucose deprivation/reoxygenation (OGD/R) in cultured cell.

Retigabine ameliorates acute stress-induced impairment of spatial memory retrieval through regulating USP2 signaling pathways in hippocampal CA1 area.

Acute stress could trigger maladaptive changes associated with stress-related cognitive and emotional deficits. Dysfunction of ion channel or receptor in the hippocampal area has been linked to the cognitive deficits induced by stress. It is known that Kv7 channel openers, including FDA-approved drug retigabine, show cognitive protective efficacy.

Hepatoprotective effect of calculus bovis sativus on nonalcoholic fatty liver disease in mice by inhibiting oxidative stress and apoptosis of hepatocytes.

Calculus bovis (CB, niu-huang) is a high-class therapeutic drug that is often used in traditional Chinese medicine. CB helps to eliminate heat and toxic components, and prevents the accumulation of phlegm and blood stasis in the liver. In Asian countries, CB Sativus (CBS), an ideal substitute for natural CB, is presently extensively used for long-term treatment of chronic liver diseases.

Protective Effect of Calculus Bovis Sativus on Dextran Sulphate Sodium-Induced Ulcerative Colitis in Mice.

Calculus Bovis Sativus (CBS) is a commonly used traditional Chinese medicine, which has been reported to exhibit antispasmodic, fever-reducing, anti-inflammatory, and gallbladder-repairing effects. The present study aims to investigate the protective effect of CBS on dextran sulphate sodium- (DSS-) induced ulcerative colitis (UC) in mice. C57BL/6 male mice were exposed to 5% DSS in drinking water.

Beneficial effect of Calculus Bovis Sativus on 17α-ethynylestradiol-induced cholestasis in the rat.

Aims: Calculus Bovis Sativus (CBS) shares similar pharmacological effects with Calculus Bovis like relieving hepatobiliary diseases. This study aims to investigate the effect and mechanism of CBS on 17α-ethynylestradiol (EE)-induced cholestasis in the rat.

Main Methods: CBS (50 and 150 mg/kg per day) was intragastrically (i.

Protective effect of Calculus Bovis Sativus on intrahepatic cholestasis in rats induced by α-naphthylisothiocyanate.

Calculus Bovis Sativus (also referred to as in vitro Cultured Calculus Bovis), an artificial substitute of natural Calculus Bovis (Niuhuang in Chinese, a traditional Chinese medicine), has been widely used to relieve fever, diminish inflammation and normalize gallbladder function in the last decade. This study aims to investigate the effects and possible mechanisms of Calculus Bovis Sativus on α-naphthylisothiocyanate (ANIT)-induced intrahepatic cholestasis in rats. Calculus Bovis Sativus (50, 100 and 200 mg/kg per day) was intragastrically (i.

2, 3, 5, 4'-Tetrahydroxystilbene-2-O-beta-D-glucoside improves gastrointestinal motility disorders in STZ-induced diabetic mice.

Oxidative stress has recently been considered as a pivotal player in the pathogenesis of diabetic gastrointestinal dysfunction. We therefore investigated the role of 2, 3, 5, 4'-tetrahydroxystilbene-2-O-beta-D-glucoside (THSG) that has a strong anti-oxidant property, in diabetic gastrointestinal dysmotility as well as the underlying protective mechanisms. THSG restored the delayed gastric emptying and the increased intestinal transit in streptozotocin (STZ)-induced diabetic mice.

Beneficial effects of THSG on acetic acid-induced experimental colitis: involvement of upregulation of PPAR-γ and inhibition of the Nf-Κb inflammatory pathway.

The polyphenolic compound 2,3,5,4'-tetrahydroxystilbene-2-O-beta-D-glucoside (THSG) has been shown to possess anti-inflammatory effects. Here, we examined the effects of THSG on experimental mice with colitis induced by acetic acid and whether the underlying mechanisms were associated with the PPAR-γ and NF-κB pathways. Mice were randomized into six equal groups: normal, colitis model, THSG (10, 30, 60 mg·kg(-1)) and mesalazine.

Effects of neferine on the pharmacokinetics of amiodarone in rats.

Amiodarone, an iodinated benzofuran derivative with predominantly class III anti-arrhythmic effects, is used to treat supraventricular and ventricular arrhythmias. The purpose of this study was to assess the potential of neferine, an effective anti-pulmonary fibrosis drug isolated from the embryo of Nelumbo nucifera Gaertner's seeds, to alter the pharmacokinetic profile of amiodarone. Experimental Sprague-Dawley rats were randomly divided into two groups.
