Indomethacin or glibenclamide treatments attenuate functional dilation of larger-diameter "feed" arterioles paired with venules in hamster cremaster muscle. We tested the hypothesis that release of cyclooxygenase products from venules is important for functional dilation of third- and fourth-order arterioles. We also tested whether ATP-sensitive potassium channels are important during functiona...

We introduce the concept of $k$-(semi)-dilation for Liouville domains, which is a generalization symplectic dilation defined by Seidel-Solomon. prove that existence property independent fillings asymptotically dynamically convex (ADC) manifolds. construct examples with $k$-dilations, but not $k-1$-dilations all $k\ge 0$. extract invariants taking value in $\mathbb{N} \cup \{\infty\}$ domains an...

BACKGROUND The optimal therapeutic schedule in patients with achalasia is still under discussion. The aim of this study was to review our institution's experience with myotomy and dilation in patients with achalasia. MATERIAL AND METHODS Clinical data were available for 59 patients who had ever had myotomy (n=38), dilation (n=21), or both procedures (n=8) between 2000 and 2007. Patients were ...

OBJECT This study was performed to compare the coronary microvascular response to adenosine 5'-triphosphate (ATP) with the response to adenosine in humans. METHODS Coronary blood flow velocity was determined using a Doppler flow wire. After intracoronary nitroglycerin infusion, intracoronary bolus injections of adenosine (20 microg) and ATP (20 microg) were performed to induce reactive hypere...

For arbitrary matrix dilation M whose determinant is odd or equal to ±2, we describe 17 all symmetric interpolatory masks generating dual compactly supported wavelet systems with vanishing moments up to arbitrary order n. For each such mask, we give explicit 19 formulas for a dual refinable mask and for wavelet masks such that the corresponding wavelet functions are real and symmetric/antisymme...

foam injection is becoming a standard conditioning agent when tunnelling with an earth-pressure balanced shield, resulting in an increasing interest in this technique. the technique is mostly based on empirical rules and experience. to be able to determine what foam and how may foam has to be injected for different soils, it is necessary to know the mechanical parameters of the foam-water-soil ...

In this paper we extend the De Giorgi notion of rectifiability of surfaces in non homogeneous Lie groups. This notion and the principal properties of Cacciopoli sets had already been proved in homogeneous Lie group, using a blow-up method, with respect to the natural dilations. In non homogeneous Lie groups no dilation are defined, so that we need to apply a freezing method, locally approximati...

Background. Dilation of malignant strictures in endoscopic ultrasound (EUS) staging of esophageal cancer is safe, but no data exists regarding the subsequent development of metastases. Aim. Compare the rates of metastases in esophageal cancer patients undergoing EUS staging who require esophageal dilation in order to pass the echoendoscope versus those who do not. Methods. We reviewed consecuti...
