The stromal cell-derived factor-1 (SDF-1) gene contains a common polymorphism, termed SDF1-3'A, in an evolutionarily conserved segment of the 3'-untranslated region (3'-UTR). We compared SDF-1 genotypes in patients diagnosed with lymphoid leukemias and lymphomas. Since the SDF1-3'A variant deletes the MspI restriction site, PCR-restriction fragment length polymorphism (RFLP) analysis was used f...
BACKGROUND Fusarium species are capable of causing a wide range of crop plants infections as well as uncommon human infections. Many species of the genus produce mycotoxins, which are responsible for acute or chronic diseases in animals and humans. Identification of Fusaria to the species level is necessary for biological, epidemiological, pathological, and toxicological purposes. In this study...
A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) test was performed to investigate the allele frequencies of the insulin-like growth factor (IGF1 and IGF2 genes) in 90 broilerchickens. A 793 bp fragment of IGF1 gene and 1146 bp fragment of IGF2 gene were amplified and digested with HinfI and Hsp92II restriction enzymes,respectively. Two types of alleles of A and B...
background: reduced bioavailability of nitric oxide (no) and the t?786c polymorphism of endothelial nitric oxide synthase (enos) gene have been reported as risk factors for the development of coronary artery disease (cad) with conflicting results. we investigated the association of plasma no levels, t?786c genetic polymorphism, and gene expression levels of enos with cad risk in an iranian subp...
The geographical distribution of the Brazilian endemic stingless bee Melipona quadrifasciata quadrifasciata Lepeletier ranges from Rio Grande do Sul to Minas Gerais states. The objective of the present study was to verify mtDNA polymorphisms among samples of M. q. quadrifasciata collected in southern Brazil. Twenty nine colonies from three localities (Blumenau and Mafra/SC and Prudentópolis/ PR...
BACKGROUND During the previous century Norway had a high incidence of tuberculosis, but no molecular epidemiological studies could be performed and these previously epidemic strains have been disappearing during the last decades. Currently, tuberculosis among native Norwegians is in the elimination phase, and it is still not known what type of M. tuberculosis was so efficiently controlled durin...
