UNLABELLED Recently, some studies have shown that delayed scanning with (18)F-FDG PET may help to differentiate malignant from benign pancreatic lesions. However, no study has evaluated the relationship between temporal changes in (18)F-FDG uptake and expression of hexokinase or glucose transporter. METHODS Twenty-one consecutive patients with pancreatic cancer were studied preoperatively by ...

The ubiquitous Na,K- and the gastric H,K-pumps are heterodimeric plasma membrane proteins composed of an alpha and a beta subunit. The H,K-ATPase beta subunit (beta HK) can partially act as a surrogate for the Na,K-ATPase beta subunit (beta NK) in the formation of functional Na,K-pumps (Horisberger et al., 1991. J. Biol. Chem. 257:10338-10343). We have examined the role of the transmembrane and...

For a scalar delay differential equation ẋ(t) + ∑m k=1 ak(t)x(hk(t)) = 0, hk(t) ≤ t, we obtain new explicit conditions for the existence of a positive solution. c © 2007 Elsevier Ltd. All rights reserved.

We shall establish two-side explicit inequalities, which are asymptotically sharp up to a constant factor, on the maximum value of |Hk(x)|e −x2/2, on the real axis, where Hk are the Hermite polynomials.

First published July 9, 2002; 10.1152/ ajprenal.00156.2002.—The H -K -ATPase 2 (HK 2) gene plays a central role in potassium homeostasis, yet little is known about its transcriptional control. We recently demonstrated t...

Holt and Klee have recently shown that every (generic) LP orientation of the graph of a d-polytope satisfies a directed version of the d-connectivity property, i.e. there are d internally disjoint directed paths from a unique source to a unique sink. We introduce two new classes HK and HK* of oriented matroids (OMs) by enforcing this property and its dual interpretation in terms of line shellin...

High-potassium diets can improve vascular function, yet the effects of potassium supplementation on ischemic stroke have not been studied. We hypothesized that dietary potassium supplementation would reduce ischemic cerebral infarct size by reversing cerebral artery hypertrophy. Six-week-old male stroke-prone spontaneously hypertensive rats (SHRSP) were fed diets containing 0.79% potassium (LK)...

Drawing from overseas practices, namely the law in England & Wales (E&W) and United States (US), this article will critically discuss whether a higher standard of proof ‘clear convincing evidence (CCE) should be adopted non-criminal proceedings Hong Kong (HK), if so, what types cases. Consequently, because 'balance probabilities ("BOP") 'beyond reasonable doubt' ('BRD') standards have t...
