Comparatively little is known about host-defense activities in the fish heart. Investigations showed that intraperitoneally injected carbon particles are actively taken up by the cardiac endothelial cells of the medaka Oryzias latipes, but less so by those of the goldfish Carassius auratus and lemon tetra Hyphessobrycon pulchripinnis. (In vitro experiments confirmed these species differences in...
Background: Scientific research has confirmed the biological activity of resveratrol, which includes its antioxidant, anti-inflammatory, cardioprotective and anticancer properties. There is no known interaction between a static magnetic field resveratrol that can modulate resveratrol’s effect on cells. Thus, main aim our was to assess co-exposure oxidation–reduction homeostasis C32 Colo829 mela...
background: oxidative stress is described as the formation of toxic effect due to the deficiency of cellular antioxidative level toward the level of reactive oxygen species (ros). the excess production of ros or the decrease in the antioxidative defense system could be the cause for oxidative stress. 7,12-dimethylbenz[a]anthracene (dmba) that is known to be the major cause the increment in lipi...
Background: As a T helper type 1 (Th1) derived cytokine, Interferon gamma (IFN-γ) is an important regulator of inflammatory immune responses. Furthermore, IFN-γ plays an essential role in defense against tumors and intracellular pathogens. This study was designed to assess the pattern of IFN-γ production in human leukemic (Jurkat and Molt-4) T cell lines in vitro. Methods: Ju...
DBA/2 mice implanted i.p. with an aclarubicin (ACR)-resistant subline of L5178Y cells survived 4- to 5-fold longer than those with the parental cells; and animals with the Adriamycin- or bleomycin-resistant subline displayed an intermediate survival period. The i.p. treatment of mice with cyclophosphamide markedly enhanced i.p. growth of the ACR-resistant cells, suggesting that a certain host d...
the history of five thousand years of human civilization (with only 292 years with no war) and the experiencesof the past two decades of our country shows that the enemies’ approach is based on strong air attack just inthe first month, and civilians bombarding begins if the spirit of national defense continues after two weeks.so the buildings in the cities are damaged in different ways by the a...
The aim of this study was the effectiveness of acceptance and commitment therapy on the organization of personality and defense styles of people with borderline personality. The research method was single-subject design A-B-A The statistical population includes all people with borderline personality disorder who were referred to the outpatient department of Zare Psychiatric Hospital and Mana Ho...
The polymorphism ATG16L1 T300A, associated with increased risk of Crohn's disease, impairs pathogen defense mechanisms including selective autophagy, but specific pathway interactions altered by the risk allele remain unknown. Here, we use perturbational profiling of human peripheral blood cells to reveal that CLEC12A is regulated in an ATG16L1-T300A-dependent manner. Antibacterial autophagy is...
The inhibition of elicitor-induced plant defense responses by the protein kinase inhibitors K252a and staurosporine indicates that defense responses require protein phosphorylation. We isolated a cDNA clone encoding Nicotiana tabacum lectin-like receptor protein kinase 1 (NtlecRK1), an elicitor-responsive gene; in tobacco bright yellow (BY-2) cells by a differential display method. NtlecRK form...
The epithelial lining of the intestine forms a barrier that separates the intestinal lumen from the host's internal milieu and is critical for fluid and electrolyte secretion and nutrient absorption. In the early 1990s, my laboratory discovered that intestinal epithelial cells could alter their phenotype and produce proinflammatory chemokines and cytokines when stimulated by pathogenic enteric ...
