Inhibition of Candida albicans virulence by moscatin from Dendrobium nobile lindl.

Candida albicans infection poses a significant global health threat. It is imperative to exploit new antifungal agents against C. albicans infections without leading to drug resistance, so that these potential agents can complement or combine with current medications to effectively treat diseases caused by C.

Exosomes from tannic acid-stimulated macrophages accelerate wound healing through miR-221-3p mediated fibroblasts migration by targeting CDKN1b.

Tannic acid (TA) and its extraction were traditionally used for treatment of traumatic bleeding in China, and in the previous study we have demonstrated that TA could accelerate cutaneous wound healing in rats. We attempted to decipher the mechanism of TA in promoting wound healing. In this study, we found that TA could enhance the growth of macrophages and inhibit the release of inflammatory cytokines (IL-1β, IL-6, TNF-α, IL-8 and IL-10) through inhibition of NF-κB/JNK pathway.

Resveratrol alleviated neuroinflammation induced by pseudorabies virus infection through regulating microglial M1/M2 polarization.

Background: Pseudorabies virus (PRV) infections in susceptible non-porcine species trigger uncontrolled inflammations and eventually fatal encephalitis. Resveratrol (Res) has broad pharmacological functions including anti-virus, anti-inflammation, and neuroprotective.

Purpose: We attempted to investigate the potential of Res in ameliorating PRV infection pathology in mice and decipher the mechanism of Res in treating PRV.

Insights into the Anti-inflammatory and Antiviral Mechanisms of Resveratrol.

Resveratrol is a naturally occurring stilbene phytoalexin phenolic compound, which has been extensively studied on its biological activity. It has been widely accepted that resveratrol possesses anti-inflammatory and antiviral activities. In this review, we summarize the anti-inflammatory dosages and mechanism and antiviral mechanism of resveratrol.

Resveratrol Inhibits Pseudorabies Virus Replication by Targeting IE180 Protein.

Resveratrol is a natural polyphenolic product in red wine and peanuts and has many pharmacological activities in humans. Our previous studies showed that resveratrol has good antiviral activity against the pseudorabies virus (PRV). However, little is known about the antiviral mechanism of resveratrol against PRV.

Resveratrol inhibits LPS-induced inflammation through suppressing the signaling cascades of TLR4-NF-κB/MAPKs/IRF3.

Resveratrol (Res) is a natural compound that possesses anti-inflammatory properties. However, the protective molecular mechanisms of Res against lipopolysaccharide (LPS)-induced inflammation have not been fully studied. In the present study, RAW264.

A dichromatic label-free aptasensor for sulfadimethoxine detection in fish and water based on AuNPs color and fluorescent dyeing of double-stranded DNA with SYBR Green I.

A dichromatic label-free aptasensor was described for sulfadimethoxine (SDM) detection. Compared with the binding of SDM-aptamer to SDM, the higher affinity of aptamer to cDNA may result in the hybridization of dsDNA. In the presence of SDM, the aptamer specifically binds to SDM, leading to a blue color of AuNPs in deposit and fluorescence at 530 nm in supernatant after adding cDNA and SGI.

Antibacterial, antidiarrheal, anti-inflammatory and analgesic activities of compound Shikuqin powder.

The MIC and MBC values of Shikuqin (SKQ) against 5 bacteria that readily cause diarrhea were measured by the broth micro dilution method. The castor oil-induced diarrhea method was used to evaluate the antidiarrheal activity. Intestinal transit and gastric emptying were also evaluated with normal and neostigmine-induced intestinal transit in rodents.

The immune-adjuvant activity and the mechanism of resveratrol on pseudorabies virus vaccine in a mouse model.

Resveratrol had shown various properties before, like immunomodulatory, anti-inflammatory and antiviral activities. Based on these properties, the present study was designed to evaluate the effects and mechanism of resveratrol as an immune-adjuvant for pseudorabies virus (PRV) vaccine. We found that oral administration of resveratrol to mice significantly increased the number of T lymphocytes in the spleen, and elevated the concentrations of antibodies and cytokines in the serum.

Label-Free Fluorescence-Based Aptasensor for the Detection of Sulfadimethoxine in Water and Fish.

Fluorescence-based aptasensors possess high sensitivity but are complicated and usually require multistep labeling and modification in method design, which severely limit the practical applications. Here, a label-free fluorescence-based aptasensor, consisting of aptamer, gold nanoparticles (AuNPs), and cadmium telluride (CdTe) quantum dots (QDs), was developed for the detection of sulfadimethoxine (SDM) in water and fish based on the specific recognition of SDM-aptamer and the inner filter effect of QDs and AuNPs. In the absence of a target, AuNPs dispersed in salt solution because of the aptamer protection, which could effectively quench the fluorescence emission of QDs, while in the presence of SDM, AuNPs aggregated due to the specific recognition of SDM-aptamer to SDM, which resulted in fluorescence recovery.

Acute and subchronic toxicity and the evaluation of safety pharmacology of Chinese herbal compound preparation "Shikuqin".

"Shikuqin" (SKQ) powder consists of three Chinese herbs: Punica granatum L, Sophora flavescens Ait, and Fraxinus rhynchophylla Hance. SKQ has been used for the treatment of diarrhea. In order to provide a comprehensive understanding of toxicity, the acute and sub-chronic toxicity and safety pharmacology of SKQ were evaluated in the present study.
