Cerebral cavernous malformations (CCM) are vascular abnormalities of the central nervous system predisposing blood vessels to leakage, leading to hemorrhagic stroke. Three genes, Krit1 (CCM1), OSM (CCM2), and PDCD10 (CCM3) are involved in CCM development. PDCD10 binds specifically to PtdIns(3,4,5)P3 and OSM. Using threading analysis and multi-template(More)
Previous comparative studies in goats revealed deletion of relA but not pknG abrogates the capacity of Mycobacterium avium subsp. paratuberculosis (Map) to establish a persistent infection. The immune response elicited by the mutant cleared infection. The objective of the present study was to extend the studies in calves and compare the proliferative(More)
To the Editor Normal neutrophilic activity converts oxygen into free radicals. The resulting Binflammatory hypoxia^ protects intestinal epi-thelium by stimulating mucus production and regulating transcription of pro-and anti-inflammatory genes. In chronic gran-ulomatous disease (CGD); however, these responses fall short [1]. In addition, chronic infection(More)
BACKGROUND There are no head-to-head randomised controlled trials (RCTs) comparing the effectiveness of biologics in ulcerative colitis (UC). We aimed to assess the cost-effectiveness of adalimumab, infliximab and vedolizumab as first-line agents to induce clinical remission and mucosal healing (MH) in UC. METHODS We constructed a decision tree based on a(More)
Phylogenic comparisons of the mononuclear phagocyte system (MPS) of humans and mice demonstrate phenotypic divergence of dendritic cell (DC) subsets that play similar roles in innate and adaptive immunity. Although differing in phenotype, DC can be classified into four groups according to ontogeny and function: conventional DC (cDC1 and cDC2), plasmacytoid(More)
Limited information is available regarding horse-associated antimicrobial resistant (AR) Escherichia (E.) coli. This study was designed to evaluate the frequency and characterize the pattern of AR E. coli from healthy horse-associated samples. A total of 143 E. coli (4.6%) were isolated from 3,078 samples collected from three national racetracks and 14(More)
BACKGROUND Pediatric inflammatory bowel disease (IBD), consisting of Crohn's disease (CD) and ulcerative colitis (UC), can result in significant morbidity requiring frequent health care utilization. Although it is known that the overall financial impact of pediatric IBD is significant, the direct out-of-pocket (OOP) cost burden on the parents of children(More)
OBJECTIVE Over 9.6 million ED visits occur annually for abdominal pain in the US, but little is known about the medical outcomes of these patients based on demographics. We aimed to identify disparities in outcomes among children presenting to the ED with abdominal pain linked to race and SES. METHODS Data from 4.2 million pediatric encounters of(More)
The lprG-p55 operon of Mycobacterium tuberculosis and Mycobacterium bovis is involved in the transport of toxic compounds. P55 is an efflux pump that provides resistance to several drugs, while LprG is a lipoprotein that modulates the host's immune response against mycobacteria. The knockout mutation of this operon severely reduces the replication of both(More)
Line defects on the surface of rutile TiO(2)(110) form in pairs separated by 1.2 nm creating a quantum well. The well is effectively closed by the presence of two charged structures at both ends separated by a distance in the 10-20 nm range. As expected for quantum confinement a long period oscillatory feature of the local density of states is observed and(More)
