Production mechanism of macromolecular activators of phagocytosis from platelets(MAPP).

Purification and characterization of macromolecular phagocytosis activators released from platelets.

Substantial amounts of macromolecular activators of phagocytosis from platelets (MAPPs) were released in response to exposure of platelets to the specific agonists thrombin and collagen and to calcium ionophore A23187. Centrifugation of the platelets in culture medium also resulted in a release of MAPPs, but not when the platelets were frozen and thawed prior to centrifugation. In an experiment...

An Apolipoprotein CIII-Derived Peptide, Hatktak, Activates Macromolecular Activators of Phagocytosis from Platelets (MAPPs)

Macromolecular Activators of Phagocytosis from Platelets (MAPPs) and their Activator Peptide, HATKTAK

Small and large macromolecular activators of phagocytosis from platelets (S-MAPP and L-MAPP, respectively) are released from activated platelets and enhance Fcγ receptor-mediated phagocytosis by neutrophils. Platelets stored in the form of platelet concentrates lose their MAPPproducing activity within 48 h, but recover it when incubated in dialyzed plasma against PBS and supplemented with Ca++....

the effects of high non fibrous carbohydrates diet on milk production, inflammation and molecular mechanism of innate immunity in lactating dairy cows

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...

‏‎faciliting lexical access for the fluent production of speech‎‏

‏‎the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
