Conclusion IgE anti-CCD should not be able to connect mast cells and basophils and release inflammatory mediators. Patients with IgE restricted to CCD have not clinical symptoms. CCD can be considered as a potential interference in atopic diagnosis; especially in polisensitized. It ‘s important to provide clinical information to laboratory test. IgE -anti CCD create a misdiagnosis of allergies ...

Little documentation of the correlation between MR imaging findings in isolated cerebellar cortical dysplasia (CCD) and its neuropathologic characteristics exists in the recent literature. We documented a postmortem neuropathologic study of a clinically and radiologically well-documented case of CCD in a neonate with severe hypotonia and status epilepticus. MR imaging revealed a global vermian ...

This report to outlines the work done by the Eta Carinae HST Treasury Project to determine the properties of the cross-dispersion point spread function for the HST Space Telescope Imaging Spectrograph (STIS) CCD. In this document we will refer to the cross-dispersion point spread function by the abbreviation: XSF. The goal of this work is to give a model for the STIS/CCD XSF which can be calcul...

Objectives: Several methods of image acquisition are accessible in dentistry. There is no overall acceptable method for image digitization so all different types of images can be comparable. The objective of this study was to compare the diagnostic accuracy of different methods of image digitization. Methods: This accuracy diagnostic test study used perceptibility curve test which first intr...

The gain of a CCD camera is the conversion between the number of electrons ("e-") recorded by the CCD and the number of digital units ("counts") contained in the CCD image. It is useful to know this conversion for evaluating the performance of the CCD camera. Since quantities in the CCD image can only be measured in units of counts, knowing the gain permits the calculation of quantities such as...

An intelligent environment employing multiple vision sensors labeled with identification features is proposed. The union of the sensing ranges of these vision sensors covers a large unknown workspace where a mobile robot can proceed to explore. The goal of this research is to accomplish mobile robot localization and navigation based on such a calibration-free sensor network. Specifically, stati...

Carotenoid cleavage dioxygenases (CCDs) are a group of enzymes that catalyze the oxidative cleavage steps from carotenoids to various carotenoid cleavage products. Some ccd genes have been identified and encoded enzymes functionally characterized in many higher plants, but little in cyanobacteria. We performed a comparative analysis of ccd sequences and explored their distribution, classificati...

Colony collapse disorder (CCD) is characterized by the unexplained losses of large numbers of adult worker bees (Apis mellifera) from apparently healthy colonies. Although infections, toxins, and other stressors have been associated with the onset of CCD, the pathogenesis of this disorder remains obscure. Recently, a proteomics study implicated a double-stranded DNA virus, invertebrate iridesce...

در این مطالعه به بررسی اثر میزان نفوذ چسب فنل فرم آلدهید بر ویژگی¬های فیزیکی و مکانیکی تخته تراشه جهت دار پرداخته شد. به منظور ایجاد تغییر در میزان نفوذ از تراشه¬های صنوبر با رطوبت¬های مختلف در سه سطح 2%، 6% و 10% استفاده گردید. تشکیل کیک با روشی خاص انجام گرفت و تخته¬ها به ضخامت 12 میلیمتر و دانسیته 650 کیلوگرم بر متر مکعب ساخته شدند. بررسی خطوط چسب با استفاده از میکروسکوپ فلوئورسنت انجام شد و...
