We tested the hypothesis that Crohn's disease (CD)-related genetic polymorphisms involved in host innate immunity are associated with shifts in human ileum-associated microbial composition in a cross-sectional analysis of human ileal samples. Sanger sequencing of the bacterial 16S ribosomal RNA (rRNA) gene and 454 sequencing of 16S rRNA gene hypervariable(More)
BACKGROUND Increasing evidence supports the central role of Paneth cells in maintaining intestinal host-microbial homeostasis. However, the direct impact of host genotype on Paneth cell function remains unclear. Here, we characterize key differences in Paneth cell function and intestinal microbial composition in two widely utilized, genetically distinct(More)
Triad of leukoencephalopathy, cerebral calcifications and cysts (LCC) is a recently reported rare disease named 'Labrune syndrome' after the first case was reported in 1996 by Labrune et al. Herein, we report a case of a 36-year-old man with mild right-sided weakness and seizures for 5 years. CT of brain revealed extensive calcification involving bilateral(More)
OBJECTIVE Although polymorphisms of the NOD2 gene predispose to the development of ileal Crohn's disease, the precise mechanisms of this increased susceptibility remain unclear. Previous work has shown that transcript expression of the Paneth cell (PC) antimicrobial peptides (AMPs) α-defensin 4 and α-defensin-related sequence 10 are selectively decreased in(More)
Culture-independent phylogenetic analysis of 16S ribosomal RNA (rRNA) gene sequences has emerged as an incisive method of profiling bacteria present in a specimen. Currently, multiple techniques are available to enumerate the abundance of bacterial taxa in specimens, including the Sanger sequencing, the ‘next generation’ pyrosequencing, microarrays,(More)
Percutaneus device closure appears to be safe and effective in patients treated for a residual shunt after initial surgical closure, as well as after two to three weeks of index myocardial infarction. The index case presented with a ventricular septal defect on second of acute myocardial infarction thrombolysed with streptokinase. The general condition of(More)
BACKGROUND The Internet has successfully been used for patient-oriented survey research. Internet-based translational research may also be possible. OBJECTIVE Our aim was to study the feasibility of collecting biospecimens from CCFA Partners, an Internet-based inflammatory bowel disease (IBD) cohort. METHODS From August 20, 2013, to January 4, 2014, we(More)
Cross-talk between the gut microbiota and the host immune system regulates host metabolism, and its dysregulation can cause metabolic disease. Here, we show that the gut microbe Akkermansia muciniphila can mediate negative effects of IFNγ on glucose tolerance. In IFNγ-deficient mice, A. muciniphila is significantly increased and restoration of IFNγ levels(More)
Amyloidosis is a collection of diseases in which different proteins are deposited as insoluble beta-pleated sheets, disrupting organ function. Distribution of these deposits may be diffuse or localized throughout the body, depending on the pathophysiology of the underlying amyloid type. Isolated deposition of amyloid proteins in lung is a very rare entity.(More)
A 22 year old male presented with breathlessness on exertion, ecchymosis, jaundice and features of worsening right heart failure for the last fifteen days. On physical examination, he had a mid diastolic murmur in the tricuspid area and an ejection systolic murmur in the pulmonary area. Bone marrow histopathology report showed an increased in megakaryocytes(More)
