Background and Aims. To explore the association of magnifying endoscopic (ME) findings with histopathology and relapse in ulcerative colitis (UC). Methods. Forty-six patients with UC underwent ME with narrow band imaging (NBI) and crystal violet staining and were followed for more than 12 months. ME findings with vital staining were classified into ME-A, regular arrangement of round to oval pit...

objective(s)cpg oligodeoxynucleotides (cpg odns) have been shown to have potent immunostimulatory adjuvant activity for a wide range of antigens. due to susceptibility of phosphodiester cpg odns (po cpg) to nuclease degradation, nuclease-resistant phosphorothioate cpg odns (ps cpg) were currently utilized in an in vivo model. in this study, according to some recently reported drawbacks with ps ...

The article considers etch pits that appear in metals and alloys during metallographic etching as an artifact. optical contrasting tools capabilities, such dark field, polarized light, differential interference contrast detecting pits, are demonstrated.

Crotaline snakes (family Viperidae, subfamily Crotalinae) are unique among snakes in the possession of facial pits situated on each side of the head between the nostril and the eye (Klauber, 1972). These organs are depressions with highly innervated membranes at their bases that have a heat-sensing function and that transmit information to the part of the brain that receives visual data (Desmou...

Isolated human fibroblast plasma membranes that were attached by their extracellular surface to a solid substratum contained numerous clathrin coated pits that could be removed with a high pH buffer (Moore, M.S., D.T. Mahaffey, F.M. Brodsky, and R.G.W. Anderson. 1987. Science [Wash. DC]. 236:558-563). When these membranes were incubated with coat proteins extracted from purified bovine coated v...

BackgroundCleft lip and cleft palate (also, known as or facial clefts), are amongst the most common congenital deformities affecting the jaw and face as well as the most common defects associated with lip and palate. Thus, the current study was an attempt to investigate the prevalence and risk factors of or facial clefts in Iranian children.Materials and Methods:The present study, was conducted...

Introduction: Cleft lip and palate is a congenital anomaly occurring in 3 in 1000 live birth. One the major concern in this patient is about cleft gap and its surgical problems. Several surgical and non-surgical procedures have been done to decrease this gap. They aimed to achieve the more esthetic results as well as feeding success. Nasoalveolar Molding (NAM) is a new method for reshaping nasa...

Cleft lip defects are usually regarded as a single entity, with the assumption that an accompanying cleft palate represents the more severe form. The authors linked data from the Medical Birth Registry of Norway with medical records from two centralized centers to provide a population-based data set. They assessed the distribution of cleft lip only and cleft lip with cleft palate by covariate. ...

PURPOSE The purpose of this study was to investigate appropriate contrast reference values (CRVs) by comparing the contrast in phantom and clinical images. MATERIALS AND METHODS Phantom contrast was measured using two methods: (1) counting the number of visible pits of different depths in an aluminum plate, and (2) obtaining the contrast-to-noise ratio (CNR) for 5 tissue-equivalent materials ...

1. This study investigated how the size of crevices might affect their effectiveness as refuges for diatom-dominated algal assemblages from the grazing minnow Campostoma anomalum. 2. Crevice size was manipulated by making fired-clay substrates, using moulds to produce eight substrates with pits from 1.17 to 22.0 mm diameter. Non-pitted clay-stones and limestone were also tested. Cages were used...
