Comparative study on the drug effects and adverse reactions of doxycycline and isotretinoin in the treatment of moderate to severe acne.

To compare the drug effects and adverse reactions of doxycycline and isotretinoin in patients with moderate to severe acne. A retrospective analysis was conducted on 98 patients with moderate to severe acne who were treated in the Affiliated Hospital of Nanjing University of Traditional Chinese Medicine from June 2020 to June 2023. They were divided into group A and group B based on actual medication use, with 49 cases in each group.

Targeted activation of ErbB4 receptor ameliorates neuronal deficits and neuroinflammation in a food-borne polystyrene microplastic exposed mouse model.

The impact of polystyrene microplastics (PS-MPs) on the nervous system has been documented in the literature. Numerous studies have demonstrated that the activation of the epidermal growth factor receptor 4 (ErbB4) is crucial in neuronal injury and regeneration processes. This study investigated the role of targeted activation of ErbB4 receptor through a small molecule agonist, 4-bromo-1-hydroxy-2-naphthoic acid (C11H7BrO3, E4A), in mitigating PS-MPs-induced neuronal injury.

The KSR1/MEK/ERK signaling pathway promotes the progression of intrauterine adhesions.

Ras kinase suppressor 1 (KSR1) serves as a scaffold protein within the RAS-RAF pathway and plays a role in tumorigenesis, immune regulation, cell proliferation, and apoptosis. However, the specific role of KSR1 in the formation and progression of fibrotic diseases, such as intrauterine adhesions (IUA), remains unclear. This study aims to investigate KSR1 expression in IUA and the mechanisms underlying its role in promoting IUA progression.

Carboxylesterase 2A gene knockout or enzyme inhibition alleviates steatohepatitis in rats by regulating PPARγ and endoplasmic reticulum stress.

Metabolic dysfunction associated steatotic liver disease (MASLD) is a widespread liver disease that progresses from simple steatosis to severe steatohepatitis stage. Despite the recognized importance of carboxylesterase 2 (CES2) in hepatic lipid metabolism, the role of CES2 in hepatic inflammation remains unclear. The rat genome encodes six Ces2 genes and Ces2a shows high expression in liver and intestine.
