Published: November 2021

An eremophilane-type sesquiterpenoid (EPS), 3-oxo-eremophila-1,7(11)-dien-12,8β-olide, has been isolated from anti-inflammatory folk herbs, . The aim of present study is to explore protective effects of EPS on lipopolysaccharide (LPS)-induced inflammatory responses in acute lung injury (ALI). EPS treatments (40 and 80 mg/kg) significantly ameliorated LPS-stimulated pathological changes in lungs. Furthermore, and mechanism studies suggest that EPS exerts its protective effects on LPS-induced ALI by regulating macrophage polarisation via suppression of TLR4/MyD88-mediated MAPK and NF-κB signaling pathways, and EPS may be useful for the prevention on ALI in the clinical setting.

Dihydromyricetin (Dih), a naturally occurring flavonoid, has been identified to exert a protective effect against ischemia/reperfusion injury. However, the detailed mechanisms remain unclear. Here we investigated the biological role of Dih in preventing hypoxia/reoxygenation (H/R) injury in cardiomyocytes.

Background: Basal cell nevus syndrome, also known as Gorlin or Gorlin-Goltz syndrome, is a hereditary condition caused by mutation in the PATCHED gene. The syndrome presents with a wide range of clinical manifestations, including basal cell carcinomas, jaw cysts, and skeletal anomalies. Diagnosis is based on specific criteria, and treatment typically includes surgical removal of basal cell carcinomas.

Multiple gene-deletion vaccinia virus Tiantan strain against mpox.

January 2025

Changchun Veterinary Research Institute, Chinese Academy of Agricultural Sciences, Changchun, 130122, People's Republic of China.

Monkeypox virus (MPXV) is an important zoonotic pathogenic virus, which poses serious threats to public health. MPXV infection can be prevented by immunization against the variola virus. Because of the safety risks and side effects of vaccination with live vaccinia virus (VACV) strain Tian Tan (VTT), we constructed two gene-deleted VTT recombinants (TTVAC7 and TTVC5).

Background: Endocrine-disrupting chemicals (EDCs) interfere with the endocrine system and negatively impact reproductive health. Biochanin A (BCA), an isoflavone with anti-inflammatory and estrogen-like properties, has been identified as one such EDC. This study investigates the effects of BCA on transcription, metabolism, and hormone regulation in primary human granulosa cells (GCs), with a specific focus on the activation of bitter taste receptors (TAS2Rs).
