To determine the morphometric landmarks and anatomical variants relevant to arthroscopic approach deep gluteal space. Twenty spaces from cadaveric specimens were dissected. The of sciatic nerve (SN) determined according Beaton Anson classification. A study distances in subgluteal space was carried out define references achieve a safe for piriformis syndrome [GT-SN=Distance greater trochanter (G...

Malectin is a conserved, endoplasmic reticulum (ER)-resident lectin that recognizes high mannose oligosaccharides displaying terminal glucose residues. Here we show that Malectin is an ER stress-induced protein that selectively associates with glycopolypeptides without affecting their entry and their retention in the Calnexin chaperone system. Analysis of the obligate Calnexin client influenza ...

objective: diabetes mellitus as the most common metabolic disease of human has wide range of oral consequences such as oral infections which could make changes in the properties of saliva. the purpose of this study was to compare the amount of salivary iga in diabetic and non-diabetic patients. materials and methods: in this case-control study, the population consisted of 40 persons including 2...

OBJECTIVE To evaluate and compare the sensitivity and specificity of the new serologic marker human antitissue transglutaminase antibodies (IgA anti-tTG) with those of antiendomysium (IgA EMA) and antigliadin antibodies (IgA and IgG AGA) for the diagnosis of celiac disease (CD). METHODS The level of IgA antibodies to tTG in serum was determined by an enzyme-linked immunosorbent assay (ELISA) ...

Abstract To limit immune responses to gut-resident microbes, mucus and the epithelial barrier physically separate host system from microbial communities. Immunoglobulin A (IgA) antibodies are known help regulate colonization functions of mucus-associated commensals. However, mechanisms whereby other isotypes, including IgG, interface with components promote tolerance MA microbes still being unr...

BACKGROUND AGA IgA II and AGA IgG II have recently been suggested as reliable tools for celiac disease (CD) diagnosis. We compared their utility for diagnosis and monitoring CD in children with that of tTG IgA, an established CD marker. METHODS We studied a cohort of 161 CD and 129 control children in whom CD was histologically confirmed or ruled out. We followed 37 children with CD on a glut...

Altogether 29 745 English blood donors were screened for IgA deficiency by double diffusion analysis; 57 had apparent absence of IgA, a frequency of 1:522. Further examination by the more sensitive haemagglutination inhibition assay revealed 34 samples having no detectable IgA, a frequency of 1:875. All donors negative by double diffusion analysis were tested for the presence of antibodies to I...
