1. Efeito dos ácidos graxos saturados, poli-insaturados e trans no desenvolvimento de aterosclerose e esteatose hepática em camundongos com ablação gênica do receptor de LDL / Effect of saturated, polyunsaturated and trans fatty acids on the development of atherosclerosis and hepatic steatosis of mice with ablation of the LDL receptor gene
Introduction: The amount and type of dietary fat play important roles on the development of cardiovascular disease (CVD) and on the development of hepatic steatosis. Saturated (SAT) and trans (TRANS) fatty acids are known as pro-atherogenic, while the polyunsaturated (POLY) fats seem to exert an antiatherogenic action. Regarding hepatic steatosis, it is know

2. Structural and functional analysis of VT1 and YP170B vitellins from the Rhabditid nematodes Oscheius tipulae and Caenorhabditis elegans. / Estudo das vitelinas VT1 e YP170B dos nematoides rabditídeos Oscheius tipulae e Caenorhabditis elegans: aspectos estruturais e funcionais.
The N-terminal region of OTI-VIT-1 was expressed and the recombinant polypeptides were purified. OTI-VIT-1 may be homologous to the vitellin YP170B from C. elegans. We identified an intron in the 5 region and two in 3region from Oti-vit-1. Monospecific antisera to PVIT1HisC confirmed that the gene Oti-vit-1 encodes VT1. The recombinant polypeptide P40-H, cor

3. Detection of Mycobacterium in clinical samples by multiprimer polymerase chain reaction
PCR utilizando vários oligonucleotídeos para detecção de espécies de micobactérias em espécimes clínicas foi padronizado. Três diferentes fragmentos genômicos: da seqüência de inserção IS6110, presente no complexo M. tuberculosis, do gene responsável por proteína específica (32kDa) do gênero e do gene mtp40 espécie-específico do M. tuberc

4. Mtp-40 and alpha antigen gene fragment amplification for the detection of Mycobacterium tuberculosis in Colombian clinical specimens
In this study, the use of Mtp-40 and alpha antigen polymerase chain reaction (PCR) amplification fragments for the precise tuberculosis (TB) diagnosis was evaluated. One hundred and ninety two different samples were obtained from 113 patients with suspected TB. Mtp-40 and alpha antigen protein genes were amplified by the PCR technique and compared to both th

5. The mtp40 gene is not present in all strains of Mycobacterium tuberculosis.
A multiple PCR-based assay that targets IS6110 and the mtp40 gene was evaluated for the rapid differentiation of Mycobacterium bovis and M. tuberculosis, two of the causative agents of tuberculosis. The IS6110 target is present in both species, whereas the mtp40 gene was thought to be specific for M.tuberculosis (P.Del Portillo, L.A. Murillo, and M.E. Patarr

6. Analysis of genetic polymorphism in the phospholipase region of Mycobacterium tuberculosis.
mtp40 was originally identified as a short genomic region that was found in strains of Mycobacterium tuberculosis but not in Mycobacterium bovis. Subsequent studies have revealed that the sequence is part of the mpcA gene, which encodes a phospholipase C. To investigate further the distribution of the mtp40 sequence, we analyzed strains of the M. tuberculosi

7. Phospholipase Region of Mycobacterium tuberculosis Is a Preferential Locus for IS6110 Transposition
Enzymes with phospholipase C activity in Mycobacterium tuberculosis have been recently described. The three genes encoding these proteins, plcA, plcB, and plcC, are located at position 2351 of the genomic map of M. tuberculosis H37Rv and are arranged in tandem. We have previously described the presence of variations in the restriction fragment length polymor

8. Evaluation of PCR in Detection of Mycobacterium tuberculosis from Formalin-Fixed, Paraffin-Embedded Tissues: Comparison of Four Amplification Assays
We compared the sensitivities and specificities of four nested PCR assays for the detection of Mycobacterium tuberculosis from formalin-fixed, paraffin-embedded tissues. Thirty-seven autopsy samples from human immunodeficiency virus-positive patients were analyzed: 15 were M. tuberculosis positive, 11 served as negative controls, and 11 were Ziehl-Neelsen po

9. Molecular Markers Demonstrate that the First Described Multidrug-Resistant Mycobacterium bovis Outbreak Was Due to Mycobacterium tuberculosis
We genetically characterized multidrug-resistant Mycobacterium tuberculosis complex strains which caused a nosocomial outbreak of tuberculosis affecting six human immunodeficiency virus (HIV)-positive patients and one HIV-negative staff member (E. Bouvet, E. Casalino, G. Mendoza-Sassi, S. Lariven, E. Vallée, M. Pernet, S. Gottot, and F. Vachon, AIDS 7:1453�

10. Multiprimer PCR system for differential identification of mycobacteria in clinical samples.
A novel multiprimer PCR method with the potential to identify mycobacteria in clinical samples is presented. The assay relies on the simultaneous amplification of three bacterial DNA genomic fragments by using different sets of oligonucleotide primers. The first set of primers amplifies a 506-bp fragment from the gene for the 32-kDa antigen of Mycobacterium

11. Molecular Characterization of Mycobacterium tuberculosis H37Rv/Ra Variants: Distinguishing the Mycobacterial Laboratory Strain†
The Mycobacterium tuberculosis strains H37Rv and H37Ra are the most commonly used controls for M. tuberculosis identification in the clinical and research laboratory setting. To reduce the likelihood of misidentification and possible cross-contamination with this laboratory neotype, it is important to be able to distinguish H37 from clinical isolates. To pro
