Hepatocyte growth factor (HGF) is a mesenchymal-derived cytokine. It exerts in vitro a motogenic effect on various target cells, which is displayed either by cell scattering, locomotion, and migration during the wound repair process of cultured cells…
To identify genes that are involved in breast cancer, suppression subtractive hybridization (SSH) was utilized to construct a breast cancer subtracted library. Differential screening of the library isolated 28 genes which by Northern analysis were hi…
PURPOSE: In this study the effects of thymosin beta4 (Tbeta4) on migration and production of laminin-5 in the human conjunctival cell line HC0597 was analyzed. METHODS: Boyden chamber assays assessed the ability of Tbeta4 to stimulate in vitro cell m…
BACKGROUND AND AIMS OF THE STUDY: Previous research has demonstrated that tenascin-C, an extracellular matrix protein involved in bone development and mineralization, was specifically present in calcified aortic valves, always in association with mat…
Platelets share structural and functional similarities with granulocytes known to participate in antimicrobial host defense. To evaluate the potential antimicrobial activities of platelet proteins, normal human platelets were stimulated with human th…
Mechanical loading is paramount in regulating both the anabolic and catabolic activities of articular cartilage chondrocytes, essential for the matrix to retain its functional integrity. We have identified thymosin beta(4) as a putative mechanically…
UNLABELLED: In this study, the roles of hematopoietic inhibitors elaborated by bone marrow endothelial cells in the proliferation and differentiation of hematopoietic progenitors were investigated. Murine bone marrow endothelial cell conditioned medi…
The beta-thymosins are a highly conserved family of small polar peptides known to bind monomeric actin and inhibit its polymerization. The beta-thymosins show a high degree of sequence conservation among all vertebrate classes and they have been also…
The legume seeds of lentil (Lens culinaris), vetch (Vicia sativa) and soybean (Glycine max, cv. Mazowia) were germinated in the dark at a constant temperature of 25 degrees C up to 168 h (24 h x 7 d). The changes in peroxyl radical-trapping capacity…
Mannitol dehydrogenases (MDH) are a family of Zn(2+)-independent long-chain alcohol dehydrogenases that catalyze the regiospecific NAD(+)-dependent oxidation of a secondary alcohol group in polyol substrates. pH and primary deuterium kinetic isotope…
The green muscle disease (GMD), described for the first time in 1968, is a cause of significant losses in the production of turkey meat. Pathological changes of different intensity are found in smaller pectoral muscles on one or both sides of the ste…
In this study, results of histopathological investigations of meat samples collected from turkeys with macroscopically recognized green muscle disease were compared with those obtained from turkeys without macroscopic signs of this syndrome. The hist…
Enzyme-catalyzed beta-elimination of sugar uronic acids, exemplified by the degradation of plant cell wall pectins, plays an important role in a wide spectrum of biological processes ranging from the recycling of plant biomass through to pathogen vir…
Grit made of crude and expanded amaranth seeds was added to meat-fat batter in order to determine its effect on its quality. Amaranthus cruentus seeds were expanded by the nonpressure method and graded by density (degree of expansion) into three frac…
The study were performed on 90 piglets of both sexes, divided into two groups, i.e. control, consisting of 30 healthy animals, and experimental, including 60 piglets with symptoms of gastroenteritis. Clinical, hematological and biochemical tests were…
The study was performed on 90 piglets of both sexes, aged from 21 to 42 days. The control group consisted of 30 healthy piglets, the experimental one included 60 piglets with symptoms of gastroenteritis. Clinical and biochemical tests were performed…
The study was performed on 20 piglets of both sexes. The control group consisted of 10 healthy piglets, the experimental, group included 10 piglets with symptoms of gastroenteritis. All the animals were subjected to euthanasia at the age of 21 or 35…
The peculiarities of the differentiation of the thymocytes in adult and old CBA/Ca mice were studied with a help of the monoclonal antibodies to different lymphoid antigens of mice. In the thymus of old mice, the portions of the CD4-CD8-, CD44+ and C…
Effects of peptide bioregulators (thymaline, epithalamine, cortexine) on systemic hemodynamics in cardiovascular and cerebrovascular affections were studied. Assessment of functional stability and quality of cardiovascular system regulation was made…
Available clinical data on aspirin-sensitive asthma (ASA) indicate that ASA patients have certain disturbances in the nervous, endocrine, immune and other body systems. It has been found that such patients have a lower melatonin (MT) production in da…
