Objectives: Aristolochia indica has been widely used in the traditional medicine for the treatment of a variety of diseases. In the present study different extracts of roots of A. indica were evaluated for their anti-inflammatory, antipruritic and mast cell stabilizing activity.
Materials And Methods: Anti-inflammatory activity was performed by compound 48/80 induced rat paw edema model and antipruritic activity by examining the incidence of scratching behavior. Mast cell stabilizing activity was performed by compound 48/80 and sheep serum induced mast cell degranulation methods.
Results: The ethanol extract (300 mg/kg) and petroleum ether extract (100 mg/kg) were found to inhibit mast cell degranulation significantly equivalent to that of standard drug ketotifen (69%) by compound 48/80 model. In sheep serum model the ethanol extracts (150 and 300 mg/kg) and petroleum ether extract (100 mg/kg) showed good mast cell stabilizing activity (66-67%). Ethanol extract at 150 mg/kg showed 70% reduction of rat paw oedema and also significantly reduced the scratching response.
Conclusion: Results suggest A. indica has good mast cell stabilizing, anti-inflammatory and antipruritic activity.

Background: The blood FGF21 expression has been previously suggested to increase in patients developing atopic dermatitis (AD) and asthma. However, its impact on atopic march is rarely analyzed. The present work focused on investigating the role of Fibroblast Growth Factor 21(FGF21) in atopic march mice and its underlying mechanisms.

Endometriosis is an inflammatory disease, involving immune cell infiltration and production of inflammatory mediators. Ferroptosis has recently been recognized as a mode of controlled cell death and the iron overload and peroxidative environment prevailing in the ectopic endometrium facilitates the occurrence of ferroptosis. In the current investigation, gene expression data was obtained from the dataset GSE7305.

Mast cell tumors (MCT) are among the most common neoplasia in dogs, representing up to 21 % of skin tumors. However, etiology and risk factors for its development remain unclear. This study aimed to reduce this knowledge gap by comprehensively analyzing 905 MCT cases diagnosed in Portugal between 2019 and 2021, using descriptive and inferential analyses.

The mortality rate of ovarian cancer (OC) remains the highest among female gynecological malignancies. Advanced age is the highest risk factor for OC development and progression, yet little is known about the role of the aged tumor microenvironment (TME). We conducted RNA sequencing and lipidomic analysis of young and aged gonadal adipose tissue from rat xenografts before and after OC formation.

Bilio-biliary anastomosis (BBA) is a critical surgical procedure that is performed with the objective of restoring bile duct continuity. This procedure is often required in cases where there has been an injury to the extrahepatic bile ducts or during liver transplantation. Despite advances in surgical techniques, the healing of BBA remains a significant challenge, with complications such as stricture formation and leakage affecting patient outcomes.
