In South America, presence of this disease is expanding along with increasing dispersion of its principal vector, the sand-fly Lutzomyia longipalpis. Feline leishmaniasis is an emerging disease in domestic cats, but epidemiological studies in endemic areas of the Amazon region of Brazil are scarce and the role of cats as reservoirs of L. infantum has been debated. The aim of this study was to investigate L. infantum infection in cats living in the Amazon biome region, using serological and molecular methods. A total of 105 cats were subjected to clinical examination and blood samples were taken for immunofluorescent-antibody (IFAT) serological evaluation, to determine anti-Leishmania antibody titers. Conventional PCR and Sanger’s sequencing targeting L. infantum chitinase and Leishmania species ribosomal internal transcribed spacer (ITS-1) encoding genes were performed on conjunctival swabs from these cats. Seropositivity was det...

CONCLUSION: When gastroenterologists encounter NAFLD/NASH patients, serum CK should be verified. If hyperCKemia, frontal baldness, a hatched face, history of cataract surgery, and grip myotonia are noted, the possibility of MD may be considered. PMID: 33033573 [PubMed]

CONCLUSIONS: As the present study was the first investigation on the coagulation status in patients with AA, elevated D-dimer levels in alopecia areata may suggest a deficient coagulation in these patients that may contribute to an increase in the risk of thrombosis. Further studies are needed to evaluate this hypothesis using a larger sample size. PMID: 33034439 [PubMed - as supplied by publisher]

This study aimed to evaluate in vitro and in vivo the wound healing effects of babassu oil. In vitro, babassu oil increased the migration of L929 fibroblasts, inhibited the production of nitric oxide by LPS-stimulated peritoneal macrophages, and increased the levels of INF-γ and IL-6 cytokines production. In vivo, babassu oil accelerated the healing process in a full-thickness splinted wound model, by an increase in the fibroblasts number, blood vessels, and collagen deposition in the wounds. The babassu oil also increased the recruitment of inflammatory cells into the wound site and showed an anti-inflammatory effec...
