since there is limited information on the simultaneous effect of drought stress and salicylic acid on yield and mucilagecontent of the medicinal herb, plantago ovata forssk is available, a pot experiment was conducted in factorial form basedon a randomized complete block design with three replications in jiroft, kerman province, south of iran. as the firstfactor, drought stress included four le...

Copper (Cu) foams with high porosity of about 63–78% were processed by the freeze-casting (FC) and space-holder (SH) methods. The FC SH techniques yielded lamellar polygonal pore structures, respectively, similar porosities. deformation behaviors two different types Cu compared using uniaxial compression a simultaneous acoustic emission (AE) video recording analysis. It was found that compressi...

We prove that if X is a countable nondiscrete completely regular space such that the function space C (X) is an absolute FaS-set, then C (X) is homeomorphic to <7°° , where a = {(x¡) e R00:*, = 0 for all but finitely many i} . As an application we answer in the negative some problems of A. V. Arhangel'skii by giving examples of countable completely regular spaces X and y such that X fails to be...

ige-mediated cell signaling, induced by cross-linking of high affinity receptor for ige (fcεri) in the presence of antigen (ag), is a well known mechanism described for mast cell activation in allergy and hypersensitivity reactions, which induces a spectrum of cellular responses such as secretion and up-regulation of cell surface fcεri. although for several years  ige  binding  to  fcεri  was  ...

While many cell types express receptors for the Fc domain of IgG (Fc gamma R), only primate polymorphonuclear neutrophils (PMN) express an Fc gamma R linked to the membrane via a glycan phosphoinositol (GPI) anchor. Previous studies have demonstrated that this GPI-linked Fc gamma R (Fc gamma RIIIB) cooperates with the transmembrane Fc gamma R (Fc gamma RIIA) to mediate many of the functional ef...

We constructed chimeric receptors to dissect the role of the transmembrane (TM) domain in cell surface expression of and phagocytosis by the chain–dependent Fc receptors Fc RIIIA and Fc RI. Fc R chimeras containing the TM and cytoplasmic (CY) domains of the chain were expressed on the cell surface and mediated an efficient phagocytic signal. In contrast, chimeras containing the Fc RIIIA TM were...
