OBJECTIVE: The purpose of this article is to illustrate the usefulness of the abduction and external rotation position in MR arthrography of the shoulder. CONCLUSION: The use of abduction and external rotation in shoulder MR arthrography can be a helpful tool that complements sequences that use conventional positions for characterizing a variety of abnormal conditions in the shoulder. 相似文献

Amyloidosis is the extracellular deposition of the fibrinous protein amyloid in one or more body sites. Amyloidosis may broadly
be classified as either primary or secondary. Primary amyloidosis is idiopathic (56%), whereas the secondary form is associated
with a chronic inflammatory or infectious process (5%), Amyloidosis is also related to multiple myeloma (26%). senescence
(5%) and where tumor like deposits occur in isolated organs without systemic involvement (8%).
Laryngeal amyloidosis is a rare discase. Surgery has been the mainstay of treatment either endoscopically or by an external
neck approach. One case of laryngeal amyloidosis, treated with endolaryngeal microsurgery and carbon dioxide laser is presented
with a follow up of 8 years. 相似文献

A significant toxicity of essential oil isolated from Achillea filipendulina Lam. was realized against two arthropod pests: Oryzaephilus surinamensis (L.) and Tetranychus urticae Koch. Probit analysis revealed LC50 values were 12.121 (10.366?±?15.235) and 6.043 (5.018?±?7.564) μl/l air for O. surinamensis and T. urticae, respectively. Essential oil analysis indicated geraniol (36.95%), borneol L (9.58%), 1,8-cineole (5.98%) and copaene were the major components. According to the results of present work, the terpene-rich essential oil of A. filipendulina can be considered as a safe alternative to the synthetic chemicals in the management of O. surinamensis and T. urticae. 相似文献

Flow cytometer is a powerful single cell analysis tool that allows multi-parametric study of suspended cells. Most commercial
flow cytometers available today are bulky, expensive instruments requiring high maintenance costs and specially trained personnel
for operation. Hence, there is a need to develop a low cost, portable alternative that will aid in making this powerful research
tool more accessible. In this paper we describe a sheath-less, on-chip flow cytometry system based on the principle of Dean coupled inertial microfluidics. The design takes advantage
of the Dean drag and inertial lift forces acting on particles flowing through a spiral microchannel to focus them in 3-D at
a single position across the microchannel cross-section. Unlike the previously reported micro-flow cytometers, the developed
system relies entirely on the microchannel geometry for particle focusing, eliminating the need for complex microchannel designs
and additional microfluidic plumbing associated with sheath-based techniques. In this work, a 10-loop spiral microchannel
100 μm wide and 50 μm high was used to focus 6 μm particles in 3-D. The focused particle stream was detected with a laser
induced fluorescence (LIF) setup. The microfluidic system was shown to have a high throughput of 2,100 particles/sec. Finally,
the viability of the developed technique for cell counting was demonstrated using SH-SY5Y neuroblastoma cells. The passive
focusing principle and the planar nature of the described design will permit easy integration with existing lab-on-a-chip
(LOC) systems. 相似文献

Transcatheter aortic valve implantation (TAVI) is a disruptive technology that has dramatically changed the way clinicians care for patients with aortic stenosis. In 15 short years, this technology has progressed from first-in-human to the standard of care for high-risk and inoperable patients with aortic stenosis. In 2016 the Canadian Cardiovascular Society published the first ever report of quality of care for TAVI in Canada. This report provided multiple insights into evaluating such care delivered to Canadians and the challenges that lie ahead. In this article, we summarize these challenges and encourage cardiologists to join the call to arms for improving quality of TAVI care in Canada. 相似文献

Maternal morbidity and mortality continue to rise in the United States, with cardiovascular disease as the leading cause of maternal deaths. Congenital heart disease is now the most common cardiovascular condition encountered during pregnancy, and its prevalence will continue to grow. In tandem with these trends, maternal cardiovascular health is becoming increasingly complex. The identification of women at highest risk for cardiovascular complications is essential, and a team-based approach is recommended to optimize maternal and fetal outcomes. This document, the second of a 5-part series, will provide practical guidance from pre-conception through postpartum for cardiovascular conditions that are predominantly congenital or heritable in nature, including aortopathies, congenital heart disease, pulmonary hypertension, and valvular heart disease. 相似文献
