Revisión sobre el uso de microRNA en la detección temprana de diabetes mellitus en caninos / Review on the use of microRNA in the early detection of diabetes mellitus in canines

Diabetes mellitus in canines corresponds to a pathology whose etiopathogenesis has not yet been fully understood, since it has a great similarity with human type 1 diabetes mellitus, but the same risk factors have not been found. New diagnostic methods have been investigated in recent years in diabetic murine models, among which microRNAs have been studied as early markers of type 1 and type 2 diabetes mellitus. In canines a homology has been found between microRNAs 21, microRNA 34, microRNA 29, and microRNA 146a with those studied in human and murine diabetics. This would imply that the study of these microRNAs may have a great impact on the early detection of diabetes in canines and be a model for the study of new microRNAs that may be implicated in the development of diabetes in humans.

Revisión del uso de insulinas sintéticas en caninos como modelo de diabetes mellitus tipo 1 / Review of the use of synthetic insulins in caninesas a model of type 1 diabetes mellitus

Because there are not related to synthetic insulin types and their specific use in canine studies in Chile, it became a literature review of the insulins present in Chile most used in dogs, to analyze and discuss data on insulin therapy diabetes mellitus, deepening mainly in the disease either both in its etiology, and epidemiology in our country, which was demonstrated through characterization incidence of canine patients with endocrine diseases at the Veterinary Hospital of the University of Chile between 2012 and 2015. Given the importance of this disease in human endocrinology, it is that studying the effects of various insulins in dogs, can generate an appropriate model level research pharmacokinetics and pharmacodynamics of insulins available in our country, which constitutes the canine model as a suitablemodel of study for human medicine, and generate future scientific research.

Efecto antifúngico de quitosán de alto peso molecular en cepas de Candida sp aisladas de muestras clínicas / Antifungal effect of high molecular weight chitosan on Candida spp isolated from clinical samples

Chitosan is a D-glucosamine polysaccharide derived from chitin that displays an antimicrobial activity against bacteria and fungi. Objective: to evaluate the antifungal effect of high molecular weight chitosan (HMWC) in clinical strains of Candida spp. Methodology: the susceptibility of forty strains of Candida spp. to HMWC was studied (16 C albicans, 11 C glabrata, 5 C. tropicalis, 5 C krusei, 2 C parapsilosis and 2 C.famatd) by broth microdilution at pH 7.0 and pH 4.0. Results: of 40 strains, only 2 were inhibited at pH 7.0 and corresponded to ATCC control strains (C. krusei 6258 and C parapsilosis 22019). On the other hand, 37/40 strains (92.5 percent) were inhibited by concentrations lower than 1.25 mg/mL of HMWC at pH 4.0. Conclusion: these results show that HMWC, presents activity against clinical Candida spp. strains, including C glabrata, and that this activity is present at acid pH (4.0). This compound could potentially be used in vulvovaginal candidiasis since it occurs at pH 4.0-4.5.
