Poroelastic Center of Dilation Revisited
… the force dipole, the centers of rotation and dilation, etc. These fundamentals solutions constitute the building blocks for various problems of practical importance and are, therefore, relatively well understood. However, a comparison of the original elastic solution for the center of dilation …

Endothelium-independent dilation in children and adolescents
Peak brachial artery dilation post-nitroglycerin (NTG) administration occurs between 3 and 5-min in adults. The purpose of this study was to identify the time to peak dilation response to sublingual NTG (0.3 mg) in youth. Endothelium-independent dilation (EID) was measured in 198 healthy (113 …

Limited Memory Space Dilation and Reduction Algorithms
… well known r-algorithm, which employs a space dilation strategy in the direction of the difference between two successive subgradients, is recognized as being one of the most effective procedures for solving nondifferentiable optimization problems. However, the method needs to store the space …

Endoscopic large-balloon dilation alone versus endoscopic sphincterotomy plus large-balloon dilation for the treatment of large bile duct stones
… sphincterotomy (EST) combined with large-balloon dilation (LBD) has been proposed as an alternative to manage large bile duct stones. However, recent reports indicate that LBD without EST may be safe and effective in this setting. One hundred thirty-one patients with large common bile duct (CBD) …

Measurement of Time Dilation by Laser Spectroscopy on Fast Stored Lithium Ions
In der hier vorgelegten Arbeit werden Frequenzmessungen an schnellen Lithium Ionen als Test der Zeitdilatation vorgestellt. Die Messungen sind am Speicherring TSR am Max-Planck-Institut für Kernphysik durchgeführt worden. Die Übergangsfrequenz eines Zwei-Niveau-Systems im Lithium Ion wird bestimmt, …

Experimental Test of Relativistic Time Dilation by Laser Spectroscopy of Fast Ions
… experiment, which measures relativistic time dilation via the transverse Doppler effect. A deviation from the prediction given by Special Relativity would disprove the Relativity Principle and, therefore, single out a physically preferred reference frame. In order to enhance the accuracy of …

Estradiol-17beta-Oxytocin Induced Cervical Dilation in Sheep: Application to Transcervical Embryo
Experiments were initiated to determine whether exogenous estradiol-17beta (E2) and oxytocin (OT) can be used to dilate the cervix and improve transcervical embryo transfer (ET) procedures for sheep. However, there was concern that the E2-OT treatment may alter luteal function and that embryo …

Test Re-Test Reliability of Brachial Artery Flow-Mediated Dilation in Healthy Adults
Ultrasonographic assessment of flow mediated dilation (FMD) is a valuable noninvasive measurement of endothelial function; it has been shown to be a useful prognostic tool for cardiovascular disease risk. However, reproducibility of FMD in the literature varies greatly (Coefficient of Variations …

Induced Cervical Dilation in Sheep: Evaluation of the Effects on Fertilization Rates and Embryonic Development
Experiments were conducted to determine the effects of a treatment used to dilate the cervix for transcervical AI and embryo transfer on pregnancy or fertilization rates in sheep. Experiment 1 was conducted as a 2 × 2 factorial, with the main effects of estradiol-17β (E2) and oxytocin (OT). On d 6 …

ULTRASOUND ASSESSMENT OF BRACHIAL ARTERY FLOW-MEDIATED DILATION FOLLOWING ACUTE KOMBUCHA TEA CONSUMPTION IN HEALTHY MEN
… function using percent change in flow mediated dilation (FMD%) as an index. Kombucha tea has many claimed health benefits, including the ability to improve endothelial function; although this has not been scientifically investigated. AIM: The primary aim was to compare acute ingestion of black …

Oxytocin-induced cervical dilation in sheep: mechanism of action and potential use for nonsurgical artificial insemination
… contractions and cervical softening allow dilation and transcervical passage of an AI pipette. Although oxytocin does not affect sperm transport (Exp. 3) or fertilization (Exp. 9), fertility after transcervical AI is decreased (Exp. 8). Cervical manipulation seems to decrease fertility, but …

Does altering brachial artery tone with lower-body negative pressure and flow-mediated dilation affect arterial stiffness?
… (LBNP). Similarly, the impact of flow-mediated dilation (FMD) on brachial artery compliance and distensibility remains unresolved, hi addition, before such measures can be used as prognostic tools, it is important to investigate the reliability and repeatability of both techniques. Using a …

The Impact of Chronic E-Cigarette Use on Flow- Mediated Dilation Elicited by a Sustained Shear Stress Stimulus
… walls (known as shear stress), which cause dilation. The standard test of endothelial function in humans involves creating a transient increase in blood flow in a large artery and measuring the endothelial dependent dilation, this is known as reactive hyperemia flow-mediated dilation …

Identifying the Molecular Cause of Extreme Endoplasmic Reticulum Dilation in Pediatric Osteosarcoma and Its Relationship to the Disease
<p>Pediatric osteosarcoma tumors are characterized by an unusual abundance of grossly dilated endoplasmic reticulum and an immense genomic instability that has complicated identifying new effective molecular therapeutic targets. Here we report a novel molecular signature that encompasses the …

Do balloons larger than 15 mm in size increase the risk of adverse events in endoscopic large balloon dilation?
Endoscopic large balloon dilation (EPLBD) using large-diameter balloons (12-20 mm) was introduced to facilitate the removal of large bile duct stones and minimize the need for endoscopic mechanical lithotripsy (EML). Much recent literature has suggested EPLBD is safe and effective for extraction of …
