introduction: this research was done to comparison directionality of drawing fixed shapes in preschoolers and primary school according to role of handedness. materials and methods: in this research causality – comparison, 160 children (80 girls and 80 boys) with mean age of 7/96 in preschool and primary school selected with randomly cluster sampling. the tests were used , handedness quest...
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...
Zoonotic cutaneous leishmaniasis caused by Leishmania major is a most common type of vector-borne disease in Iran. The pentavalent antimonial drugs have been used in the treatment of cutaneous leishmaniasis for a long time, but drug resistance and some of serious side effects have been reported. Thus, discovery and development of new therapeutic candidates are needed. The CM11 peptide ...
Experimental chronic (45-day-old) skin lesion in hamster hind foot induced by Leishmania (Viannia) lainsoni infection showed the presence of promastigote forms in the tissue, inside parasitophorous vacuoles, as assessed by transmission electron microscopy. Experimental in vitro interaction (24 and 48 h) between Leishmania (V.) lainsoni and J774-G8 macrophage cells also demonstrated the same pro...
