The developing chick retina undergoes at least two discrete periods of programmed cell death. The earlier period coincides with the main onset of neuron birth and migration (embryonic day 5-7), whereas the latter one corresponds to the well-documented process of retinal ganglion cell death following tectal innervation (embryonic day 10-14; Rager, G. H.(More)
The effects of neurotrophins brain-derived neurotrophic factor and neurotrophin-3 on cultured dissociated cells from chick retina were studied at several embryonic ages from day 4 to day 13. Precursor cells from days 4-7 retinas proliferated in vitro and, after 20 h in culture, a proportion of them underwent spontaneous differentiation, as judged by both(More)
Clinical and biological studies on nodal marginal zone lymphoma (NMZL) are hampered by the lack of specific diagnostic markers and the low reproducibility of this diagnosis. A comparative expression-profiling study has shown a set of markers to be differentially expressed in NMZL compared with follicular lymphoma (FL), including myeloid cell nuclear(More)
Neurotrophin 3 (NT-3) had specific high-affinity receptors (HNT-3R) in the developing chick retina at all ages between embryonic day (E) 4 and E14. The affinity of HNT-3R for 125I-NT-3 did not change with the developmental state. A dissociation constant (kd) of 13 pM was obtained. However, the amount of HNT-3R appeared to be developmentally regulated; the(More)
Mucosal candidiasis is common in human immunodeficiency virus (HIV) infection. Susceptibility to such infections may be attributed to reduced host defense mechanisms and/or virulence of the organism. In the present study, we compared the virulence of mucosal Candida albicans isolates from HIV-infected people, with and without fluconazole-refractory(More)
BACKGROUND AND PURPOSE Apoptosis is present in human atherosclerotic lesions. Nuclear factor-kappaB (NF-kappaB) is involved in the transcriptional regulation of the proapoptotic protein Fas ligand (FasL). We have analyzed NF-kappaB activation and FasL expression in atherosclerotic plaques and peripheral blood mononuclear cells (PBMCs) of patients with(More)
OBJECTIVE To describe a novel cadaver-based model for practicing renal transplant (RT) surgery. DESIGN A simulating model using cadavers preserved by Thiel's method is developed to teach surgical anatomy and operative skills in RT surgery. Participants were asked to complete a voluntary, anonymous survey evaluating perceptions of the model and comparing(More)
Cardiovascular infections due to Salmonella enterica are infrequently reported, so their clinical features, prognosis, and optimal treatment are not completely known. Mortality associated with aortitis and endocarditis caused by nontyphoidal Salmonella remains exceedingly high. In this review of cases of cardiovascular infections due to Salmonella enterica(More)
Based on the presence of cytokines in whole saliva and their association with resistance and susceptibility to infectious disease, the present study was designed to evaluate the diagnostic potential of a large panel of cytokines and chemokines in saliva. Despite the endogenous presence of Th1/Th2 and pro-inflammatory cytokines and several chemokines in(More)
