BACKGROUND Assessment of intestinal activity and severity of Crohn's disease (CD) is crucial to guide treatment. In this study, we aimed to investigate the accuracy of spectral computed tomography (CT) in this assessment and make a comparison with conventional CT. METHODS A total of 50 patients with ileocolonic CD underwent spectral CT scanning. Conventional CT and spectral CT images were rec...

Tetrodotoxin-resistant (TTX-R) Na channels are 1,000-fold less sensitive to TTX than TTX-sensitive (TTX-S) Na channels. On the other hand, TTX-R channels are much more susceptible to external Cd 2 block than TTX-S channels. A cysteine (or serine) residue situated just next to the aspartate residue of the presumable selectivity filter “DEKA” ring of the TTX-R channel has been identified as the k...

Background: Historically bare metal stents were considered standard of care for STsegment elevation acute myocardial infarction (STEMI). There is limited data on STEMI patients treated for primary angioplasty with ResoluteTM zotarolimus-eluting stent (R-ZES) and the everolimus-eluting stent (EES). Methods: The global RESOLUTE program enrolled STEMI patients in 4 trials: RESOLUTE-All Comers (RAC...

We prove that the generalized Carleson operator Cd with polynomial phase function is of strong type (p, r), 1 < r < p < ∞; this yields a positive answer in the 1 < p < 2 case to a conjecture of Stein which asserts that for 1 < p < ∞ we have that Cd is of strong type (p, p). A key ingredient in this proof is the further extension of the relational time-frequency perspective (introduced in [5]) t...

Boros and Füredi (for d = 2) and Bárány (for arbitrary d) proved that there exists a positive real number cd such that for every set P of n points in R d in general position, there exists a point of R contained in at least cd ( n d+1 ) d-simplices with vertices at the points of P . Gromov improved the known lower bound on cd by topological means. Using methods from extremal combinatorics, we im...

Consider the moment curve in the real Euclidean space R defined parametrically by the map γ : R → R, t → γ(t) = (t, t, . . . , t). The cyclic d-polytope Cd(t1, . . . , tn) is the convex hull of the n, n > d, different points on this curve. The matroidal analogues are the alternating oriented uniform matroids. A polytope [resp. matroid polytope] is called cyclic if its face lattice is isomorphic...

We have analysed new R-band photometry of globular clusters in NGC 6166, the cD galaxy in the cooling flow cluster A2199. In combination with the earlier B photometry of Pritchet & Harris (1990), we obtain B−R colours for ∼ 40 globular clusters in NGC 6166. The mean B−R is 1.26 ± 0.11, corresponding to a mean [Fe/H] = −1 ± 0.4. Given that NGC 6166 is one of the most luminous cD galaxies studied...

BACKGROUND Crohn's disease (CD) is associated with depression. It is unclear if psychosocial interventions offer benefit for depressive symptoms during active CD. In this secondary analysis of a larger study of treating depression in pediatric inflammatory bowel disease, we assessed whether cognitive behavioral therapy (CBT) would differentiate from supportive nondirective therapy in treating d...

A flexible, transparent, single-walled carbon nanotube (SWCNT) film electrode was prepared by vacuum filtering methods, followed by photolithographic patterning of a photoresist polymer on the SWCNT surface. The morphology of the SWCNT film electrode surface was characterized using a field-emission scanning electron microscope coupled to an energy-dispersive X-ray spectrophotometer. The electro...

Abstract Background Intestinal ultrasound (IUS) scores were developed for adults and children with Crohn’s disease (CD) but have not been externally validated endoscopy. This study aimed to validate all CD IUS Methods Prospective cross-sectional of who underwent colonoscopy within 60 days. The International Bowel Ultrasound Segment Activity Score (IBUS-SAS), Simple (SUS-CD), (SUAS-CD), Pediatri...
