Identification of a broad array of leukaemia-associated antigens is a crucial step towards immunotherapy of haematological malignancies. However, it is frequently hampered by the decrease of proliferative potential and functional activity of T cell clones used for screening procedures. Transfer of the genes encoding the T cell receptor (TCR) alpha and beta(More)
PURPOSE The superior graft-versus-leukemia (GVL) effect of the female-to-male stem cell transplantation is partially independent from the concomitant graft-versus-host reactivity. However, the antigenic basis of this selective GVL response remains enigmatic, because no H-Y antigens with hematopoietic-restricted expression were identified. In this study, we(More)
Laser photocoagulation of bleeding ulcer is one of the effective methods of endoscopic hemostasis. Experimental studies were carried out on resected stomach preparation. The preparations were studied histologically. Clinical trial was conducted in 43 patients with gastric and duodenal ulcer for hemostasis and prophylaxis of recurrent bleeding. Initial(More)
PURPOSE Donor T cells directed to hematopoietic minor histocompatibility antigens (mHag) are appealing tools for adoptive immunotherapy of hematological malignancies after allogeneic stem cell transplantation (allo-SCT). Toward the development of a convenient strategy for ex vivo generation of human leukocyte antigen (HLA) class II--restricted mHag-specific(More)
The therapeutic effect of a human leucocyte antigen (HLA)-identical allogeneic stem cell transplantation (allo-SCT) for the treatment of haematological malignancies is mediated partly by the allogeneic T cells that are administered together with the stem cell graft. Chronic myeloid leukaemia (CML) is particularly sensitive to this graft-versus-leukaemia(More)
In 1999-2001 400 patients in Saratov have been surveyed. The persons directed by the military-medical commissions of military registration and enlistment offices, have made 60.7% (243 patients). This group was a basis of research. Comparison of results of inspection of the recruits, suffering a bronchial asthma of a various degree of expressiveness, has(More)
Three-dimensional (3D) customized scaffolds capable to mimic a native extracellular matrix open new frontiers in cells manipulation and advanced therapy. The major challenge is in a proper substrate for in vitro models on engineered scaffolds, capable to modulate cells differentiation. Here for the first time we demonstrate novel design and functionality of(More)
OBJECTIVE The purpose of this review is to evaluate the current literature regarding the efficacy of pulmonary artery catheterization, to assess the quality of existing randomized controlled trials and to make recommendations for future studies. DATA SOURCE A Medline search was conducted of English language studies published between 1970 and 1996 using as(More)
The authors examined the influence of the preparation metaqualone on some aspects of adrenergic metabolism-respiration, phosphorilation and ATP-ase activity of brain mitochondria of a rat in order to discover pharmacobiochemical mechanism of action. The experimental data showed that administration of metaqualon in a dose of 70 mg per kg of body weight(More)
