An infinite graph Γ is minor excluded if there is a finite graph that is not a minor of Γ. We prove that minor excluded graphs have finite Assouad-Nagata dimension and study minor exclusion for Cayley graphs of finitely generated groups. Our main results and observations are: (1) minor exclusion is not a group property: it depends on the choice of generating set; (2) a group with one end has a ...

background: host immune system response against blood group antigens is a major problem in blood transfusions, especially forthalassemic patients. thus, an approach was proposed coating the red blood cell (rbc) surface by polyethylene glycol.objectives: this study aimed to obtain the optimal simultaneous camouflge of the major and minor antigens by activated methoxypolyethylene glycol (mpeg) wi...

there are reports from different countries that some types of glaucoma are associated with blood groups. this cross-sectional study was performed on 400 glaucomatous patients [100 patients in each group of primary open angle glaucoma (poag), chronic angle closure glaucoma (cacg), pseudoexfoliative glaucoma (pexg) and primary congenital glaucoma (pcg)] and 400 blood donors as control group to as...

background:   objective: to determine pregnancy outcome of women with β-thalassemia minor.   materials and methods: in this retrospective, case-control study in two universities affiliated hospitals in shiraz, all pregnancies occurred between 2006 and 2008 were included. patients were divided in two groups regarding the presence of β-thalassemia minor. patients in case and control groups were m...

The clinical significance of ABO and Rhesus blood group systems has been well documented. The objective of this study was to determine the frequency of ABO and Rhesus blood groups in blood donors in Lahore, Pakistan, with a view to generate data with multipurpose future practicalities in the field of medicine. Blood groups of 3000 blood donors were determined by commercially available standard ...

INTRODUCTION Renal involvement is a rare complication of β-thalassemia. Both tubular and glomerular dysfunction might occur in these patients. The aim of this study was to evaluate and compare kidney function in the major, intermedia, and minor variants of β-thalassemia. MATERIALS AND METHODS Renal tubular and glomerular function of 72 patients with β-thalassemia (25 major, 23 intermedia, and...

The A reagent: The A reagent (Table 1 ) was an unabsorbed, isoimmune antiserum. It was produced in a sheep named A, which received five intrajugular injections, at five-day intervals, of 5 ml of citrated blood from a sheep named B. The antiserum was collected five days after the last injection. Sheep A was of blood-group R in the R 0 system, and a preimmunization sample of her serum contained n...

Blood group antigens of the H, ABO, Lewis, and historical “P” blood groups are defined by small carbohydrate epitopes expressed as posttranslational modifications on glycoproteins, mucins, and glycolipids. Their synthesis is complex and dependent on several distinct glycosyltransferases and interrelated biosynthetic pathways. In many cases, carbohydrate antigens share features of more than one ...
