Purpose: The aim of this study was to determine the anti-allergic activity of propolis in an ovalbumin-induced rat model of allergic rhinitis.
Materials And Methods: This prospective experimental study was conducted at Hakan Çetinsaya Clinical and Experimental Animal Research Center with 30 rats. After sensitization of all rats with 0.3mg intraperitoneal ovalbumin plus 30mg aluminum hydroxide for 14days (first phase), rats were divided to five groups. In the second phase of the study 10μL of ovalbumin was applied to each nostril for 21days. Together with second phase, ketotifen (n:6), oral propolis (n:6), intranasal propolis (n:6) and intranasal mometasone furoate (n:6) were given to rats. A control group (n:4)(salin) and sham group (n:2) were planned. Symptoms were assessed on days 19, 22, 25, 30 and 35, resulting in 5 symptom scores: symptom scores 1-5. On day 35, nasal tissue was removed and histological examination was performed.
Results: When rats that received systemic and intranasal propolis were compared to controls, ciliary loss, inflammation, increase in goblet cells, vascular proliferation, eosinophil count, chondrocytes and allergic rhinitis symptom score were found to be decreased (p<0.05).
Conclusions: It was found that propolis had anti-allergic effects on allergic symptom scores and nasal histology.

Diabetes mellitus, particularly type 2 diabetes mellitus (T2DM), poses a significant global health challenge. Traditional management strategies primarily focus on glycemic control; however, there is a growing need for comprehensive approaches addressing the complex pathophysiology of diabetes complications. The recent study by Attia explores the potential of a novel therapy combining metformin with cholecalciferol (vitamin D3) and taurine to mitigate T2DM-related complications in a rat model.

Background: Therapies for cartilage restoration are of great interest, but current options provide limited results. In salamanders, interzone (IZN) tissue can regenerate large joint lesions. The mammalian homolog to this tissue exists during fetal development and exhibits remarkable chondrogenesis in vitro.

Despite advancements in preclinical and clinical spinal cord stimulation (SCS) research, the mechanisms of SCS action remain unclear. This may result from challenges in translatability of findings between species. Our systematic review (PROSPERO: CRD42023457443) aimed to comprehensively characterize the important translational components of preclinical SCS models, including stimulating elements and stimulation specifications.

Objective: Osteoarthritis (OA) is the most common form of chronic joint disease, affecting mainly the elderly population. This disorder is caused by cartilage degeneration with complex changes in the chondrocyte phenotype. Inorganic pyrophosphate (PPi) was shown to counteract the detrimental effect of interleukin (IL)-1β challenging in an in vitro OA model based on rat articular chondrocytes.

Erythroferrone (ERFE) has emerged as a potential biomarker for the erythropoiesis response following recombinant human erythropoietin (rHuEPO) treatment. While the association between ERFE and hemoglobin (HGB) response to rHuEPO is well-established in nonanemic conditions, such correlation and ERFE kinetics in anemic states remain unclear. We employed two rat models of anemia, chronic kidney disease (CKD) anemia and chemotherapy-induced anemia (CIA), to determine ERFE kinetics and its correlation with HGB responses after rHuEPO administration.
