Cordycepin, a natural derivative of adenosine from , can inhibit the replication of the dengue virus (DENV). Here, we investigated its antiviral and anti-inflammatory effects in DENV infected cells. Cordycepin significantly inhibited DENV-2 infection, virion production, and viral protein synthesis. It also reduced DENV-induced cytokine/chemokine production, including RANTES, IP-10, IL-6, and TNF-α. Mechanistically, cordycepin targeted the DENV NS5 protein, suppressing RANTES expression and hindering viral replication. Additionally, it inhibited the NF-κB pathway, leading to reduced nuclear translocation and signaling deactivation. PCR array analysis revealed cordycepin's suppression of 46 genes associated with DENV-induced inflammation. These findings highlight cordycepin's dual potential as an antiviral and anti-inflammatory agent against DENV, making it as a promising candidate for dengue treatment, targeting both viral and host factors.

The interplay between the cytokine network and antipsychotic treatment in schizophrenia remains poorly understood. This study aimed to investigate the impact of psychotropic medications on serum levels of IFN-γ, IL-4, TGF-β1, IL-17, and BAFF, and to explore their relationship with psychopathological features. We recruited 63 patients diagnosed with schizophrenia in the acute phase, all of whom were either drug-naïve or had been drug-free for at least three months.

In this manuscript, the effects of two extracts from were tested: (a) an extract titrated to 49.7% of andrographolide and obtained from leaves of the plant: (b) the pure andrographolide titrated to 99%. The extracts were dissolved in 1-butanol and tested on tumor lines (MCF7 and SH-SY5Y) and the non-tumor line (Huvec) to understand the effects on cell proliferation.

Rosmarinic acid (RA) is a natural active compound widely found in many plants belonging to the family of , , and so on, which has various important bioactivities, including being anti-oxidative, anti-inflammatory, antiviral, etc. Herein, novel hydrophilic magnetic molecularly imprinted polymers (HMMIPs) with a regular core-shell structure were successfully developed using RA as a template molecule, acrylamide (AM) as a functional monomer, N-N 'methylenebisacrylamide (MBA) as a cross-linking agent, and water as the porogen. After a series of characterization and adsorption performance analyses, it was found that HMMIPs are hydrophilic with an adsorption capacity of 8.

Background: Little is known about the efficacy of preexposure prophylaxis (PrEP) or what biologic factors may influence HIV transmission in transgender men (TGM). In this study, we sought to explore the effect of testosterone on the vaginal microbiome, cervicovaginal fluid (CVF) tenofovir concentrations, and levels of CVF inflammatory markers in TGM on PrEP.

Methods: Cervicovaginal fluid was collected from 13 TGM (7 using testosterone) and 32 cisgender women (CGW) on PrEP.

Background: Chronic active Epstein-Barr virus (CAEBV) colitis is a rare disease with clinical and endoscopic manifestations very similar to those of inflammatory bowel disease (IBD). In clinical practice, it is easy to be misdiagnosed and mistreated, leading to poor clinical outcomes.

Case Presentation: We report a case of a 56-year-old Chinese woman who presented with 6 years of intermittent severe diarrhea, fever, and abdominal pain.
