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...
Mitochondrial DNA polymorphisms were analyzed in of 1,610 randomly chosen adult men from 11 different regions from southeastern Europe (Croatians, Bosnians and Herzegovinians, Serbians, Macedonians and Macedonian Romani). MtDNA HVS-I region together with RFLP sites diagnostic for main Euroasian and African mtDNA haplogroups were typed to determine haplogroup frequency distribution. The most fre...
PURPOSE Four single-nucleotide polymorphisms (SNPs) in the TGIF, lumican, TGFB1, and HGF genes have been declared to be associated with high myopia in Chinese living in southeast China, but none of them has been confirmed by additional studies. This study was conducted to verify the reported positive association results by analysis of subjects from the same region. METHODS DNA was prepared fr...
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...
Genetic factors can determine the high variability observed in response to lipid-lowering therapy with statins. Nonetheless, the frequency of single nucleotide polymorphisms (SNPs) and their impact can vary due to ethnicity. Because the Chilean population carries a strong Amerindian background, the objective of this study was to evaluate the influence of apolipoprotein E (APOE) variants (rs4293...
We investigated the associations between SLC11A1 polymorphisms and susceptibility to tuberculosis (TB) in Chinese Holstein cattle, using a case-control study of 136 animals that had positive reactions to TB tests and showed symptoms and 96 animals that had negative reactions to tests and showed no symptoms. Polymerase chain reaction (PCR) sequencing and the restriction fragment length polymorph...
The present study was planned with the objective to amplify 5’NCR Insulin-like growth factor 1 (IGF1) and 3’UTR Prolactin receptor (PRLR) genes using caprine specific primers by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) in Surti Mehsana goats. IGF1 gene found be monomorphic on restriction digestion HaeIII, which revealed only one genotype GG both allele frequ...
