The hydrodynamic properties of the C-reactive protein in solution (pH 6.8) were studied using quasi-elastic light scattering and size-exclusion liquid chromatography. It was shown that the solution containing the C-reactive protein represents a polydisperse system. The values of the translation diffusion coefficient and the apparent molecular weight of the(More)
Sixty-five patients with the fourth stage colon cancer were subjected to the combined surgical and immunotherapy. The following conclusions are made: (1) surgical elimination of the bulk of tumor mass is a necessary prerequisite for effective immunotherapy; (2) vaccination with autological tumor cells accompanied with bacille bilié de Calmette-Guérin (BCG)(More)
Here we have shown that β-cytoplasmic actin acts as a tumor suppressor, inhibiting cell growth and invasion in vitro and tumor growth in vivo. In contrast, γ-cytoplasmic actin increases the oncogenic potential via ERK1/2, p34-Arc, WAVE2, cofilin1, PP1 and other regulatory proteins. There is a positive feedback loop between γ-actin expression and ERK1/2(More)
The process of penetration of a proteolytic enzyme applied to the surface of burn wound into the depth of necrotic tissue was considered. The model approximation describes three factors by a series of mathematical equations: inward-directed enzyme diffusion, counter-flow filtration of interstitial fluid (exudates), and irreversible inactivation of the(More)
The hydrodynamic properties of the C-reactive protein (CRP) at different pH were studied using quasi-elastic light scattering, size-exclusion liquid chromatography, and nonreducing gel electrophoresis. It was shown that a CRP solution at pH 5.0-7.2 presents a polydisperse system the major component of which is the native pentameric CRP. At pH 4.0-4.5, CRP(More)
Alveolar rhabgomyosarcoma is a highly malignant, small blue cell pediatric soft tissue tumor. Identification of micrometastases in alveolar rhabdomyosarcoma is important because the poor prognosis associated with this subgroup necessitates a modified therapeutic regimen. Since the obtained lymph node specimen can be very small; rhabdomyosarcoma cells are(More)
Eight cases of infantile deep soft tissue fibrosarcoma were examined. The tumor consists of neoplastic fibroblasts and myofibroblasts which differ from each other ultrastructurally. Well-differentiated collagen-forming neoplastic fibroblasts form one-half of infantile fibrosarcoma. Immunohistochemically and ultrastructurally immature embryonic-like(More)
The molecular mass and sedimentation coefficient of native C-reactive protein in solution were determined by analytical ultracentrifugation in the presence and absence of calcium ions. Pentameric C-reactive protein was shown to be the major macroscopic form of this protein in solution. The removal of calcium ions from solution caused decompaction of the(More)
The diagnosis of low-grade fibromyxoid sarcoma was made in 8 patients. The lesions were 2-17 cm in the lower extremities and trunk. One patient had a long history of painless subcutaneous and intramuscular mass (median 1 year). All tumors showed predominantly the typical hypocellularity and cytologic features of typical low-grade fibromyxoid sarcoma;(More)
