The caloric curve for mononuclear configurations is studied with a schematic model. We investigate the dependence of the entropy on the density and effective mass profiles. A plateau in the caloric curve is a direct result of decreasing density and the destruction of correlations with increasing excitation. The mononuclear regime is metastable with respect to binary fission at low excitation en...

Agents known to increase intracellular levels of cyclic 3', 5'-adenosine monophosphate (cyclic AMP) were examined for their effect on tissue factor generation by mononuclear cells cultured with E. coli endotoxin. Aminophylline, an inhibitor of phosphodiesterase, and epinephrine, a beta-adrenergic agent, showed an inhibitory effect, and these effects were reversible. Moreover, dibutyryl cyclic A...

Cellular immunity to cartilage proteoglycans may be responsible for sustaining chronic inflammation in ankylosing spondylitis. This hypothesis was examined by measuring peripheral blood and synovial fluid mononuclear cell proliferation in five preparations of human cartilage proteoglycan monomer in vitro. Peripheral blood mononuclear cells from 25 patients and synovial fluid mononuclear cells f...

The caloric curve for mononuclear configurations is studied with a model that allows for both increased surface diffusness and self-similar expansion. The evolution of the effective mass with density and excitation is included in a schematic fashion. The entropies, extracted in a local-density approximation, confirm that nuclei posess a soft mode that is predominately a surface expansion. We al...

features of chronic periodontal disease and it has been demonstrated (Goodson et al., 1974; El Attar, 1976) that inflamed gingivae contain much higher concentrations of prostaglandin E, than normal tissue. Chronically inflamed gingivae are infiltrated with large number of macrophages, lymphocytes and plasma cells, which interact in the immune response. Products of these cell interactions may mo...

The in vitro differentiation of homogeneous populations of monocyte-like cells from the unstimulated mouse peritoneal cavity is described. Under the conditions employed, a progressive increase in cell size occurs without significant cell division. This process is characterized morphologically by the accumulation of phase-dense and neutral red-positive granules, mitochondria, and lipid droplets....

Abstract Genital mycoplasmosis is a condition present in bovine production systems, and the most important agents involved are Mycoplasma bovis , bovigenitalium Ureaplasma diversum . Some aspects of their pathogenesis remain unclear. This study was designed order to evaluate ability stimulate mononuclear cells from endometrium, vagina peripheral blood cycling healthy cows produce nitric oxide (...

Dinuclear gold complexes have the ability to interact with one or more substrates in a dual-activation mode, leading to different reactivity and selectivity than their mononuclear relatives. In this contribution, this difference was used to control the catalytic properties of a gold-based catalytic system by site-isolation of mononuclear gold complexes by selective encapsulation. The typical du...

The spontaneous increase in the transcription of the heat shock protein (hsp 70) gene in peripheral blood mononuclear cells of patients with active systemic lupus erythematosus (SLE) is shown by nuclear run on transcription assay. The transcription of hsp 70 gene in the peripheral blood mononuclear cells of five patients with active SLE was more than 10 times greater than that in five normal he...

In decalcified (5% nitric acid) and undecalcified (glycol-methacrylate or resin embedded) routinely processed bone specimens osteoclasts against resorbing surfaces were identified with monoclonal antibodies directed against leucocyte common antigen (LCA) (PD7/26, 2B11), CD68 (KP1), and gpIIIa (Y2/51) but not against HLA-DR (CR3/43 and Ta11B5). Mononuclear cells on resorbing surfaces and occasio...
