Background: No stent is yet available for tapering coronary arteries. The purpose of the present study is to evaluate the applicability, efficacy and safety of a novel tapered, polymer-free sirolimus eluting stent (t-PFSES) specifically designed for tapering coronary arteries. Methods: 28 pigs underwent the placement of 56 oversized stents (control, n = 28, t-PFSES, n = 28), and quantitative co...

BACKGROUND Conventional approaches for benzodiazepine tapering have their limitations. Anecdotal studies have shown that acupuncture is a potential treatment for facilitating successful benzodiazepine tapering. As of today, there was no randomized controlled trial examining its efficacy and safety. The purpose of the study is to evaluate the efficacy of using electroacupuncture as an adjunct tr...

Early observations led Sanio [Wissen. Bot., 8, (1872) 401] to state that xylem conduit diameters and lengths in a coniferous tree increase from the apex down to a height below which they begin to decrease towards the tree base. Sanio's law of vertical tapering has been repeatedly tested with contradictory results and the debate over the scaling of conduit diameters with distance from the apex h...

Supercontinuum generation (SCG) in a tapered chalcogenide fiber is desirable for broadening mid-infrared (or mid-IR, roughly the 2-20 μm wavelength range) frequency combs(1, 2) for applications such as molecular fingerprinting, (3) trace gas detection, (4) laser-driven particle acceleration, (5) and x-ray production via high harmonic generation. (6) Achieving efficient SCG in a tapered optical ...

BACKGROUND Benzodiazepines (BZD) are the most widely used sedative-hypnotics, and evidence is rapidly accumulating suggesting potential BZD dependence, association of chronic use with adverse effects and a definite abstinence syndrome produced by withdrawal. AIMS The present investigation followed prospectively long-term BZD users over 1 year following graded BZD withdrawal in terms of clinic...

To determine the tapering of human nerve fibres, rostral and caudal root pieces of cauda equina nerve roots were removed and nerve fibre diameter distributions were constructed for 4 myelin sheath thickness ranges for the two sites, and compared with each other. The reduction of the group diameter in the different alpha-motoneuron groups was 0.2 % per 13 cm. Accounting for systematic errors, th...

Background: Intestinal atresia is a life-threatening problem requiring early active intervention. The aim of the study was to compare management outcomes between Duodenal-Atresia (DA) and Jejunoileal-Atresias (JIA). The secondary objective was to analyse tapering enteroplasty versus end-to-end anastomosis in JIA. Materials and Methods: Retrospective descriptive analysis of patients operated be...
