Proliferation, DNA ploidy, p53 overexpression and nuclear DNA fragmentation in six equine melanocytic tumours.
pathological entity in horses, but further phenotypic characterization of these tumours is lacking. Six melanocytic tumours from five horses (two metastatic and four benign) were examined by Ki67, PCNA and p53 ...
Lack of protection in mice and necrotizing bronchointerstitial pneumonia with bronchiolitis in guinea pigs immunized with vaccines directed against the hsp60 molecule of Mycobacterium tuberculosis.
Publication Type: Peer reviewed scientific article Authors: Turner, O C; Roberts, A D; Frank, A A; Phalen, S W; McMurray, D M; Content, J; Denis, O; D'Souza, S; Tanghe, A; Huygen, K; Orme, I M Source: Infect Immun, Volume 68, Issue 6, Number 3679, p. ...
Characterization of the culture filtrate-specific cytotoxic T lymphocyte response induced by Bacillus Calmette-Guérin vaccination in H-2b mice.
recognized and killed by CF-specific CTL, demonstrating the lack of TAP requirement for this presentation. However, recognition of target cells by CTL was abolished when carried out in the presence of ...
Characterization of the culture filtrate-specific cytotoxic T lymphocyte response induced by bacillus Calmette-Guérin vaccination in H-2b mice
efficiently recognized and killed by CF-specific CTL, demonstrating the lack of TAP requirement for this presentation. However, recognition of target cells by CTL was abolished when carried out in the presence ...
Induction of cytotoxic T-cell responses against culture filtrate antigens in Mycobacterium bovis bacillus Calmette-Guérin-infected mice.
of CD4 + T cells and their secretion of interleukin 2. The lack of cytotoxic response in H-2d mice cannot be explained by impaired cytokine production or by a defect in Ag presentation by H-2d ...
Lucigenin- and luminol-enhanced chemiluminescence in turkey monocytes5195
primarily results from the peroxidase activity, this lack of myeloperoxidase may explain the observed lower responses to the different stimuli, in the presence of a luminol. In contrast, lucigenin-enhanced CL ...
Cellular pathways involved in the ex vivo expression of bovine leukemia virus.
Activation Abstract: Bovine leukemia virus (BLV) is the etiologic agent of enzootic bovine leukosis. The virus adopts a strategy based on the lack of viral expression in vivo; only very rare BLV-infected ...
A computerized nationwide network for nosocomial infection surveillance in Belgium.
Seventy percent of the small-size hospitals (< 200 beds) did not participate, mainly because of shortages of manpower. A lack of collaboration from clinicians was a problem in most participating ...
YscN, the putative energizer of the Yersinia Yop secretion machinery.
a modified YscN protein lacking box A. This mutant, impaired in Yop secretion, can be complemented in trans by a cloned yscN gene. We conclude that YscN is a component of the Yop secretion machinery using ATP. ...
Role of YadA in resistance of Yersinia enterocolitica to phagocytosis by human polymorphonuclear leukocytes55
a lack of chemiluminescence. The expression of YadA at the bacterial surface also reduced the phagocytosis by PMN s. Finally, we measured the survival of Y. enterocolitica cells confronted with PMN s by ...
