Emerging data support a role for antibody Fc-mediated antiviral activity in vaccine efficacy and in the control of HIV-1 replication by broadly neutralizing antibodies. Antibody-mediated virus internalization is an Fc-mediated function that may act at the portal of entry whereby effector cells may be triggered by pre-existing antibodies to prevent HIV-1 acquisition. Understanding the capacity o...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
تاثیر تجویز پروژسترون بر دانسیته ی عروقی آندومتر رحم موش در زمان پیش از لانه گزینی و زمان لانه گزینی
هدف از این مطالعه بررسی تأثیر تجویز هورمون پروژسترون بر دانسیته ی عروقی آندومتر رحم موش پس از تحریک تخمک گذاری در زمان پیش از لانه گزینی و در زمان لانه گزینی بود. بدین منظور از 30 سر موش نژاد nmri با میانگین سنی بین 8-6 هفته استفاده شد و به صورت تصادفی به شش گروه تقسیم شدند.در سه گروه کنترل، گروه تحریک تخمک گذاری و گروه تزریق پروژسترون تقسیم بندی شدند. در گروه کنترل حاملگی کاذب القا شد و در گرو...
from its emergence till present time marxist principles has undergone great changes since their promulgation by marx. many theorists and thinkers set at rectifying marxist tenets and introducing those of their own while others advocated its main concepts and attempted at improving them. among marxist philosophers who had an intensive study of marxs ideology, is louis althusser whose reflections...
The opportunistic yeastlike fungi of the genus Candida comprise three species which are proteolytic in vitro. Among them, C. albicans and C. tropicalis are of foremost medical importance. However, a strict correlation between extracellular proteolytic activity and virulence is opposed by the low virulence of the third proteolytic species, C. parapsilosis. We purified the secretory acid proteina...
background and aims: ovarian cancer is one of most common causes of cancer related women's mortalities. human papilloma virus is a known factor concerning cervical cancer but its role in causing ovarian cancer is not yet verified. a few studies also identified hpv dna in ovarian carcinoma tissues. however, some studies did not detect hpv dna in ovarian carcinoma tissues. in this article, we inv...
IgA nephropathy (IgAN) is characterized by glomerular co-deposition of IgA and complement components. Earlier studies showed that IgA activates the alternative pathway of complement, whereas more recent data also indicate activation of the lectin pathway. The lectin pathway can be activated by binding of mannose-binding lectin (MBL) and ficolins to carbohydrate ligands, followed by activation o...
Previous studies in children have shown that Haemophilus influenzae type b (Hib) polysaccharide conjugate vaccines can reduce nasopharyngeal carriage of H. influenzae and provide herd immunity and suggest that this effect is mediated through mucosal antibodies. As this phenomenon may operate in other invasive bacterial infections which are propagated by nasopharyngeal carriage, mucosal antibody...
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
background: calprotectin is cytotoxic agent that its anti-tumor effects are governed through suppression of topoisomerase ii a key enzyme in apoptosis. in previous studies, cytotoxicity and apoptotic effects of calprotectin are shown on different cancer cell lines, but not human gastric cancer cell lines. in the present study, cytotoxicity and apoptotic effects of calprotectin on human gastric ...
