Human lysozyme is an important natural non-specific immune protein that is highly expressed in breast milk and participates in the immune response of infants against bacterial and viral infections. Considering the medicinal value and market demand for human lysozyme, an animal model for large-scale production of recombinant human lysozyme (rhLZ) is needed. In this study, we generated transgenic cloned cows with the marker-free vector pBAC-hLF-hLZ, which was shown to efficiently express rhLZ in cow milk. Seven transgenic cloned cows, identified by polymerase chain reaction, Southern blot, and western blot analyses, produced rhLZ in milk at concentrations of up to 3149...

Lutzomyia (Nyssomyia) anduzei has been recognized as a secondary vector of Leishmania guyanensis in the Brazilian Amazon region. Since L. anduzei is anthropophilic, co-exists in areas of high leishmaniasis transmission and has been found infected with L. guyanensis, the understanding of the vector population structure and of the process responsible for it is paramount to the vector management and control efforts. In this study we analyzed 74 and 67 sequences of the COI and Cytb loci, respectively, from mitochondrial DNA, aiming to estimate the intra-population genetic variability and population structure in six L...

OBJECTIVES: Several recent studies suggest that intermediate vaginal flora (IVF) is associated with similar adverse health outcomes as bacterial vaginosis (BV). Yet, it is still unknown if IVF and BV share the same correlates. We conducted a cross-sectional and exploratory analysis of data from women screened prior to enrolment in a microbicide trial to estimate BV and IVF prevalence and examine their respective correlates. METHODS: Participants were interviewed, examined and provided blood and genital samples for the diagnosis of IVF and BV (using Nugent score) and other reproductive tract infections...

Nitrate respiration by the N(2)-fixing symbiotic bacteria Bradyrhizobium japonicum USDA110 is mediated by a Nap (periplasmic nitrate reductase) encoded by the napEDABC genes. Expression of a transcriptional fusion of the nap promoter region to the reporter gene lacZ, P(napE)-lacZ, was very low in aerobically grown cells of USDA110, but expression was induced approx. 3-fold when the cells were cultured under microaerobic conditions, and 12-fold when nitrate was added to the microaerobic incubation medium. The P(napE)-lacZ fusion was not expressed in the fixL 7403, fixJ 7360 and fixK(2) 9043 mutant strains...

A pentapeptide, Boc-Leu-Ac8c-Ala-Leu-Ac8c-OMe 1, an octapeptide, Boc-Leu-Ac8c-Ala-Leu-Ac8c-Ala-Leu-Ac8c-OMe 2 and a tripeptide, Boc-Aib-Ac8c-Aib-OMe 3 containing the 1-aminocyclooctane-1-carboxylic acid residue (Ac8c) were synthesized and conformationally characterized by x-ray diffraction studies in the crystal state. Peptides 1 and 2 were also studied by NMR in CDC13 solution. Peptide 1 adopts a purely 3(10)-helical conformation in crystals, stabilized by three intramolecular 1 <-- 4 hydrogen bonds. Peptide 2 in crystals is largely 3(10)-helical with distortion in the backbone at the N-terminus by the insertion of a water molecule between Ac8c (2) CO and Ala (6) NH groups...
