Ameliorative effect of apple cider vinegar and p-coumaric acid combination in Ex ovo antimicrobial and in vivo wound healing models

Background: Apple cider vinegar (ACV) is most commonly used in sweet and sour Chinese cuisine. This study aimed to overcome the side effects of raw ACV, by increasing the concentration of p-Coumaric acid (p-CA), a polyphenolic component of ACV. The combination (diluted ACV with p-CA) has also been compared with individual raw ACV and p-CA to confirm if the overall dosage of the ACV can be reduced to avoid side effects and if the combination therapy had any better effect than the individual component itself. Objective: To evaluate and compare antioxidant, antimicrobial, and wound healing effects of ACV and p-CA combination with individual components ACV and p-CA. Methods: The antimicrobial properties of the samples were assessed by determining the Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) using the broth microdilution method, and zone of inhibition (ZOI) and an ex ovo study was also done to evaluate the antimicrobial effect of the samples in live embryo. For the evaluation of the test samples excision wound was created in Swiss male albino mice weighing 25–30 g of either sex to estimate parameters like wound contraction rate, WBC and platelet count, SOD and GSH levels. Histopathological analysis of the skin was also done. Result: In DPPH and ABTS antioxidant assays, the combined sample (ACV + p-CA) had lower IC50. The combination therapy also showed the best antimicrobial potential against P. aeruginosa and B. subtilis. In this context, ex-ovo antimicrobial study results showed that diluted ACV + p-CA treated live embryo samples had the least bacterial growth after 48 h, in comparison with non-treatment group as well as individually ACV and p-CA treated samples. In vivo study depicted that the highest dose of the combination test sample had the best wound contraction rate and antioxidant marker enzymes elevation compared to diseased control proving the potency to restore the wound healing progression. Conclusion: ACV and p-CA combination can be used with daily intake as this combination can prevent microbial contamination and oxidative stress additionally can repair wounds more safely than raw ACV

A comprehensive review of the novel therapeutic targets for the treatment of diabetic cardiomyopathy

Diabetic cardiomyopathy (DCM) is characterized by structural and functional abnormalities in the myocardium affecting people with diabetes. Treatment of DCM focuses on glucose control, blood pressure management, lipid-lowering, and lifestyle changes. Due to limited therapeutic options, DCM remains a significant cause of morbidity and mortality in patients with diabetes, thus emphasizing the need to develop new therapeutic strategies. Ongoing research is aimed at understanding the underlying molecular mechanism(s) involved in the development and progression of DCM, including oxidative stress, inflammation, and metabolic dysregulation. The goal is to develope innovative pharmaceutical therapeutics, offering significant improvements in the clinical management of DCM. Some of these approaches include the effective targeting of impaired insulin signaling, cardiac stiffness, glucotoxicity, lipotoxicity, inflammation, oxidative stress, cardiac hypertrophy, and fibrosis. This review focuses on the latest developments in understanding the underlying causes of DCM and the therapeutic landscape of DCM treatment
