background functional constipation (fc) and constipation-predominant irritable bowl syndrome (cibs)are two main subtypes of constipation that can be distinguished by the rome ii criteria. measuring colonic transit time (ctt) is an easy and cost effective way to evaluate constipation. this study was conducted to compare the ctt in patients with fc and cibs. materials and methods those patients w...

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...

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  ...

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...

background: functional constipation (fc) is one of the important digestive disorders in pediatrics. its prevalence varies in different communities. the purpose of this study was to determine the prevalence of fc in our area between the school children and the impact of school on it. methods: this study was done on 4 to 12 years old children of nine schools and kindergartens of amirkola, (2007)....

The binding sites on human IgG1 for human Fc gamma receptor (Fc gamma R) I, Fc gamma RIIa, Fc gamma RIIb, Fc gamma RIIIa and neonatal FcR have been mapped. A common set of IgG1 residues is involved in binding to all Fc gamma Rs, while Fc gamma RII and Fc gamma RIII utilize distinct sites outside this common set. In addition to residues which abrogated binding to the Fc gamma R, several position...

current global water shortage and water pollution problem are some of the crucial issues in theworld, especially in the arid zones. the wastewater reuse was investigated the efficiency of fecal coliform(fc) removal using the intermittent media infiltration (imi) with varying soil content and natural porousmedia (sand, zeolite, vermicompost and charcoal), and its prediction was introduced by app...

BACKGROUND Despite poor evidence and high costs, fibrinogen concentrate (FC) represents one of the most frequently used hemostatic agents in exsanguinating trauma. The aim was to assess whether the administration of FC in severely injured patients was associated with improved outcomes. METHODS Patients documented in the Trauma Registry of the German Society for Trauma Surgery (primary admissi...
