(1) Interaction of genetic risk factors confers increased risk for metabolic syndrome: the role of peroxisome proliferator-activated receptor γ.[TOP]

Pubmed ID :24200052
Publication Date : 2014/01/09
The aim of the study was to estimate the influence of interactions between peroxisome proliferator-activated receptor γ (PPARγ) and target genes lipoprotein lipase (LPL), interleukin 6 (IL6), angiotensin converting enzyme (ACE), and angiotensin II type 1 receptor (AT1R) on metabolic syndrome (MetSy) and its traits.

(2) IS6110 restriction fragment length polymorphism typing of drug-resistant Mycobacterium tuberculosis strains from northeast South Africa.[TOP]

Pubmed ID :23617199
Publication Date : 2013/04/26
Tuberculosis (TB) remains a deadly infectious disease affecting millions of people worldwide; 95% of TB cases, with 98% of death occur in developing countries. The situation in South Africa merits special attention. A total of 21,913 sputum specimens of suspected TB patients from three provinces of South Africa routinely submitted to the TB laboratory of Dr. George Mukhari (DGM) Hospital were assayed for Mycobacterium tuberculosis (MTB) growth and antibiotic susceptibility. The genetic diversity of 338 resistant strains were also studied. DNA isolated from the strains were restricted with Pvu II, transferred on to a nylon membrane and hybridized with a PCR-amplified horseradish peroxidase 245 bp IS6110 probe. Of the 338 resistant strains, 2.09% had less than 5 bands of IS6110, and 98% had 5 or more bands. Unique restriction fragment length polymorphism (RFLP) patterns were observed in 84.3% of the strains, showing their epidemiological independence, and 15.7% were grouped into 22 clusters. Thirty-two strains (61.5%) from the 52 that clustered were from Mpumalanga, 16/52 (30.8%) from Gauteng, and 4/52 (9.6%) from Limpopo province. Clustering was not associated with age. However, strains from male patients in Mpumalanga were more likely to be clustered than strains from male patients in Limpopo and/or Gauteng province. The minimum estimate for the proportion of resistant TB that was due to transmission is 9.06% (52-22 = 30/331). Our results indicate that transmission of drug-resistant strains may contribute substantially to the emergence of drug-resistant tuberculosis in South Africa.

(3) [Allele genotype analysis of Plasmodium vivax merozoite surface protein 1 (PvMSP-1) from Dangdong, Liaoning Province].[TOP]

Pubmed ID :23072145
Publication Date : 2012/10/17
Nested PCR method was used to amplify the Plasmodium vivax merozoite surface protein 1 (PvMSP-1) gene fragment containing the ICB5 and ICB6 region from Plasmodium vivax in Liaoning Province. The PCR products were digested by Pvu II restriction endonuclease and the digested fragments were observed by 1.5% agarose gel electrophoresis, and all followed by sequencing analysis and comparison. In 11 field isolates of P. vivax, two kinds of DNA fragments with 470 and 400 bp were produced respectively. After PvuII digestion, two Sal-1 type fragments (120 and 350 bp) were obtained from 5 samples of 470 bp. Single band of 400 bp appeared in 1 samples as Belem type. Two bands of 120 and 280 bp appeared from another 1 sample as recombination type III, and other 4 bands with 120 and 240 bp as Korean isolate. The principal types of PvMSP-1 alleles exist in malaria endemic areas in Liaoning Province with no mixed infection of two different type alleles.

(4) Detection and molecular characterization of bovine leukemia viruses from Jordan.[TOP]

Pubmed ID :22914962
Publication Date : 2012/11/27
Bovine leukemia virus (BLV) is distributed worldwide. BLV has many effects on the health status and productivity of infected animals and is a potential risk for humans. In this study, we aimed to investigate the presence of and genotype bovine leukemia viruses on Jordanian dairy farms. Nested PCR coupled with RFLP and direct sequencing of a partial fragment of the env gene were carried out. Two BLV genotypes were found, genotypes 1 and 6. These genotypes were identified by nested PCR-RFLP of 444 bp of the env gene by restriction digestion with HaeIII, Bcl I and Pvu II. However, BLV-Jordan-10 seems to represent an entirely new genotype in our phylogenetic analysis. The nucleotide sequence identity between these two Jordanian BLV genotypes (1 and 6) was 96.2 %. The nucleotide sequence identity between Jordanian BLV genotype 1 and other reference BLV genotype 1 strains ranged from 99 % to 99.5 %. The nucleotide sequence similarity of the Jordanian BLV genotype 6 to other BLV genotypes ranged from 90 % to 96.7 %. A neutralizing motif and CD8(+) T-cell epitope were found in the env protein of both Jordanian isolates. In this study, we documented the presence of two BLV genotypes (1 and 6) on Jordanian dairy farms.

(5) Using ITS2 PCR-RFLP to generate molecular markers for authentication of Sophora flavescens Ait.[TOP]

Pubmed ID :22413146
Publication Date : 2012/03/12
Dried root of Sophora flavescens Ait. is a medicinal material occasionally misused or adulterated by other species similar in appearance. In this study the internal transcribed spacer (ITS) regions of DNA samples of S. flavescens Ait. collected from different areas of Taiwan were amplified by polymerase chain reaction (PCR) and compared. The effectiveness of using ITS2 PCR restriction fragment length polymorphism (RFLP)-generated markers to differentiate S. flavescens Ait. from possible adulterants was also evaluated.

(8) Characterization of temperature inducible promoters from a novel rolling circle replicating plasmid of Enterococcus faecium DJ1.[TOP]

Pubmed ID :22192842
Publication Date : 2012/04/23
Limited studies have been performed on the characterization of small size plasmids of Enterococcus faecium with the intention of evaluating the strength of their promoters in Escherichia coli. The complete nucleotide sequence (3.825 Kb) and structural organization of E. faecium DJ1 cryptic plasmid pNJAKD is presented. Seven promoter sequences from the pNJAKD plasmid of E. faecium have been identified. The regions coding for the putative promoters were either amplified using PCR based techniques or chemically synthesized as oligonucleotides of different sizes. These were subsequently cloned in the pEGFP vector at the Pvu II site. The efficiency of putative promoter fragments were measured using the intensity of eGFP fluorescence in E. coli JM101, DH5α and BL21(DE3), among which AKD3 exhibited moderate to strongest promoter activity at temperatures of 30, 37, and 42°C.
