background: in this study, two-dimensional gel electrophoresis (2-de) method was applied to determine and compare the protein spots expressed in the two field isolates of leishmania major and recovered from the patients who were clinically sensitive and resistant to glucantime® treatment. methods: leishmania parasites were isolated from the cutaneous lesions of two cl infected patients in shira...

objective(s) leishmania can lead to a broad spectrum of diseases, collectively known as leishmaniasis. the a2 gene/ protein family could be one of the most eligible candidate factors of virulence in visceral leishmaniasis (vl). the previous results confirmed that in leishmania infantum, several a2 proteins are abundantly expressed by the amastigote, but not the promastigote stage. as there are ...

Hematite (α-Fe2O3) nanorods were synthesized by hydrothermal method using Cetyltrimethylammonium bromide (CTAB) as a surfactant agent. To study optical, nanostructural properties, and to control the morphology and shape of nanorods, 0.025 mol L-1, 0.05 mol L-1 and 0.1 mol L-1 concentration of CTAB were used. Moreover, the effect of interaction between bovine serum albumin (BSA) A9418-5G protein...

background: the mechanisms of virulence and species differences of leishmania parasites are under the influence of gene expression regulations at posttranscriptional stages. in iran, l. major and l. tropica are known as principal agents of cutaneous leishmaniasis, while l. infantum causes visceral leishmaniasis. methods: as a preliminary study, we compared the proteome mapping of the above thre...

To obtain a better understanding of the mycorrhizas as an elicitor, and precursor feeding effects on the protein content and TIAs biosynthesis in Catharanthus roseus L., foliar application of four concentrations of tryptophan (0, 150, 250 and 350 mg/l) on some growth parameters and chemical compositions of mycorrhizal plants were investigated. The results revealed that the total protein content...

Background: During the last two decades, significant advances have been made in the fields of lactococcal genetics and protein expression. Lactococcus lactis (L. lactis) is an effective vector for protein expression and can be used as an antigen delivery system. Hence, L. lactis is an ideal candidate for mucosal immunotherapy. Profilin (Che a 2), the major allergen in Chenopodium album, is one ...
