A study was made in rural regions around Neiriz city, Fars province in the south of the Islamic Republic of Iran during 2002-03 to further investigate a new focus of zoonotic cutaneous leishmaniasis. Meriones libycus was the dominant rodent (100% of 65 rodents collected) and 4.6% were naturally infected with the amastigote form of Leishmania spp. Promasigotes were identified as L. major. This c...
In this study, a methanolic extract from Echinaster (Othilia) echinophorus was evaluated for activity against Leishmania amazonensis. The extract showed activity against the promastigote and amastigote forms with IC50 values of 62.9 and 37.5 microg.mL-1 respectively. This extract showed a moderate toxicity on macrophages from BALB/c mice. A dose of 100 mg/kg/day was effective when administered ...
purpose: to separate and characterize orbital fat-derived stem cells (ofscs) and compare its cellular and molecular properties with those of bone marrow-derived mesenchymal stem cells (mscs) and adipose-derived stem cells (ascs). methods: stem cells from orbital fat, abdominal fat and bone marrow aspirates have been isolated. we assessed stem cell specific cell surface markers using cytometry, ...
Cutaneous leishmaniasis is the most common form of leishmaniasis caused by flagellate protozoa of the genus Leishmania transmitted by sand fly bites. Old World leishmaniasis is endemic in the Mediterranean Sea and the neighbouring countries. We present a case of a 10-year-old boy with a cutaneous leishmaniasis in form of papules on the nose, right and left lower leg. Histopathological examinati...
The aim of this study was to characterize clinical field isolates of Leishmania spp. obtained from patients with American Tegumentary Leishmaniasis (ATL) who live in Goiás state, Brazil. The presumed areas of infection were in Goiás, Tocantins, and Pará states. Three isolates of parasites were identified as L. (Viannia) braziliensis and one as L. (V.) guyanensis. The in vitro growth profiles we...
As part of our ongoing antikinetoplastid structure–activity relationship study focused on positions 2 and 8 the 3-nitroimidazo[1,2-a]pyridine scaffold, we were able to introduce a phenylthioether moiety at both position in one step. Using previously reported synthetic route developed laboratory, obtained 6-chloro-3-nitro-8-(phenylthio)-2-[(phenylthio)methyl]imidazo[1,2-a]pyridine 74% yield. The...
