Heterologous expression of the insect SVWC peptide WHIS1 inhibits invasion into A549 and HeLa epithelial cells.

(), a microbe commonly isolated from patients with vaginal tract infections, transforms from yeast to hyphae and produces many toxins, adhesins, and invasins, as well as biofilms resistant to antifungal antibiotic treatment. Effective agents against this pathogen are urgently needed. Antimicrobial peptides (AMPs) have been used to cure inflammation and infectious diseases.

[Mechanism of Sijunzi Decoction in treatment of Alzheimer's disease based on UPLC-Q-TOF-MS, network pharmacology, and experimental verification].

The study identified the blood-entering components of Sijunzi Decoction after gavage administration in rats by UPLC-Q-TOF-MS/MS, and investigated the mechanism of Sijunzi Decoction in treating Alzheimer's disease by virtue of network pharmacology, molecular docking, and experimental verification. The blood-entering components of Sijunzi Decoction were identified based on the mass spectra and data from literature and databases. The potential targets of the above-mentioned blood-entering components in the treatment of Alzheimer's disease were searched against PharmMapper, OMIM, DisGeNET, GeneCards, and TTD.

Treponema pallidum (Syphilis) Antigen TpF1 Induces Activation of Macrophages and Accelerates P2X7R-Induced NLRP3-Dependent Release of IL-1β.

Background: Syphilis is a chronic infectious disease caused by Treponema pallidum (Tp) infection, which causes local inflammation in the host. TpF1 is an oligomeric protein expressed by the Tp-infected host that can induce the host immune response. There are few studies regarding the role of TpF1 in macrophage activation and the subsequent release of cytokines.

[Relationship between fluoride exposure, orthopedic injuries and bone formation markers in patients with coal-burning fluorosis].

Chronic exposure to fluoride is a public health problem worldwide. We explored the relationship between fluoride exposure, orthopedic injuries and bone formation markers alkaline phosphatase (ALP), bone Gla protein (BGP) in participants with coal-burning fluorosis in Hehua Village (coal-burning fluorosis endemic area) in Zhijin County of Guizhou Province and Zhangguan Village (non-fluoride contaminated area) in Anshun City of Guizhou Province. Environmental samples were collected and fluoride contents were examined using a fluoride ion-selective electrode.

Quantitative hepatitis B core antibody level is a new predictor for treatment response in HBeAg-positive chronic hepatitis B patients receiving peginterferon.

A recent study revealed that quantitative hepatitis B core antibody (qAnti-HBc) level could serve as a novel marker for predicting treatment response. In the present study, we further investigated the predictive value of qAnti-HBc level in HBeAg-positive patients undergoing PEG-IFN therapy. A total of 140 HBeAg-positive patients who underwent PEG-IFN therapy for 48 weeks and follow-up for 24 weeks were enrolled in this study.

Antithrombotic activities of aqueous extract from Gardenia jasminoides and its main constituent.

Context: Gardenia jasminoides J. Ellis (Rubiaceae) is a shrub tree species distributed all over the world. Now its pharmacological activities such as anti-atherosclerosis have been extensively studied.

[Association between IgG antibody against the C-terminal region of the preS1 protein of hepatitis B virus and the early response to interferon therapy in chronic hepatitis B].

Objective: To determine the relationship between IgG antibody against the C-terminal region of the preS1 protein of hepatitis B virus and the early response to interferon therapy in chronic hepatitis B.

Methods: 69 patients with chronic hepatitis B virus (genotype B) infection were recruited in this study. 42 patients were treated with interferon-a-1b or a-2b, and 27 patients were treated with PEG interferon (a-2a).
