A Mass of Pancreatic and Gastric Heterotopia Causing a Small Bowel Obstruction in a 61-Year-Old Male
Heterotopic tissue is a congenital anomaly that has been previously reported. Gastric and pancreatic heterotopia are among the most studied ones. Herein, we describe a case of a combined pancreatic and gastric heterotopia that formed a mass and caused a small intestine obstruction in a 61-year-old male. We also did a brief literature review of cases with gastric and pancreatic heterotopia in ad...
OBJECTIVE To define the clinical, radiologic, and genetic features of periventricular heterotopia (PH) with Ehlers-Danlos syndrome (EDS). METHODS Exonic sequencing and single stranded conformational polymorphism (SSCP) analysis was performed on affected individuals. Linkage analysis using microsatellite markers on the X-chromosome was performed on a single pedigree. Western blotting evaluated...
Mutation analysis of the DCX gene and genotype/phenotype correlation in subcortical band heterotopia
PURPOSE To compare computed tomography (CT) number measurement consistency under different beam hardening conditions in phantom experiment between dual-energy spectral CT and conventional CT imaging. MATERIALS AND METHODS A phantom with 8 cells in periphery region and 1 cell in central region were used. The 8 conditioning tubes in the periphery region were filled with 1 of the 3 iodine soluti...
Subcortical band heterotopia (SBH) or double cortex is associated with significant impairments in neocortical function including mental retardation and epilepsy. Mutant alleles of DCX in humans typically cause SBH in females and lissencephaly in males, whereas Dcx null mutations in mice neither disrupt neocortical neuronal migration nor cause SBH formation. In utero RNA interference (RNAi) of D...
Molecular layer heterotopia of the cerebellar primary fissure are a characteristic of many rat strains and are hypothesized to result from defect of granule cells exiting the external granule cell layer during cerebellar development. However, the cellular and axonal constituents of these malformations remain poorly understood. In the present report, we use histochemistry and immunocytochemistry...
Malformations of the human neocortex are commonly associated with developmental delays, mental retardation, and epilepsy. This study describes a novel neurologically mutant rat exhibiting a forebrain anomaly resembling the human neuronal migration disorder of double cortex. This mutant displays a telencephalic internal structural heterotopia (tish) that is inherited in an autosomal recessive ma...
Patients with malformations of cortical development and epilepsy may have a variety of abnormal brain findings, including abnormal gyral patterns, cortical thickening, decreased volume of white matter, and increased diffusion of white matter. The status of individual white matter fiber tracts, however, is unknown. We present a case of bilateral frontal schizencephaly and subcortical heterotopia...
Following Grischuk and Sidorov [Phys. Rev. D 42 (1990) 3413] in putting the Bogolubov-Hawking coefficient of Schwarzschild black-holes in the squeezing perspective, we provide a short discussion of Schwarzschild black holes as radiometric standards. In this work I will give arguments in favour of taking Schwarzschild black holes (SBH) as blackbody simulators, most probably the best ones. Even b...
Despite recent advances in DNA sequencing by hybridization it is still a random shotgun method. Even if one manages to routinely sequence short DNA fragments by SBH these fragments have to be assembled into the final genomic sequence. Recently different additional biochemical experiments were suggested which potentially may drastically increase the resolving power of SBH. However biologists fre...
