Objective To investigate factors associated with enrollment and participation in cardiac rehabilitation (CR) in Korea. Methods Patients admitted to four university hospitals with acute coronary syndrome between June 2014 and May 2016 were enrolled. The Cardiac Rehabilitation Barriers Scale (CRBS) made of 21-item questionnaire and divided in four subdomains was administered during admission. C...

Cardiac rehabilitation (CR) services improve various clinical outcomes in patients with cardiovascular disease, but such services are underutilized, particularly in women. The aim of this study was to identify evidence-based barriers and solutions for CR participation in women. A literature search was carried out using PubMed, EMBASE, Cochrane, OVID/Medline, and CINAHL to identify studies that ...

Chromium is a contaminant of concern that is found in drinking water in its soluble, hexavalent form [Cr(VI)] and that is known to be toxic to eukaryotes and prokaryotes. Trivalent chromium [Cr(III)] is thought to be largely harmless due to its low solubility and inability to enter cells. Previous work has suggested that Cr(III) may also be toxic to microorganisms but the mechanism remained elu...

دی بنز (b،f)(1،4) اکسازپین یک عامل اشک آورناتوان کننده و یک واسطه در سنتز لوکسازپین(داروی ضد جنون)، اموکساپین(داروی ضد افسردگی) می باشد. مشتقات دیگر آن نیز به عنوان مسکن و یا درمان انواع بیماری ها مفید هستند. دو روش متفاوت و با استفاده از مواد اولیه مختلف برای تهیه دی بنز (b،f)(1،4) اکسازپین (cr) وجود دارد. تفاوت این دو روش در تقدم و یا تاخر واکنش های ایمیناسیون یا اتریفیکاسیون در مرحله اول می ...

The objectives of this study are to evaluate the efficiency of removal of hexavalent chromium (Cr(VI)) in a sequencing batch reactor (SBR) and to ascertain the fate of Cr(VI) in the treatment process. An SBR was operated with the FILL, REACT, SETTLE, DRAW and IDLE periods in the time ratio of 2:12:2:1.5:6.5 for a cycle time of 24 h. The study was divided into 5 phases with the addition of 0.5, ...

Several previous studies of exposure to chromium waste in New Jersey have shown that Cr levels are elevated in household dust in homes adjacent to waste sites and that Cr levels in the urine of residents near sites are also elevated compared to control populations. It has not been possible until now, however, to examine these external and internal measures of exposure together in a large popula...

New emission branching fraction (BF) measurements for 183 lines of the second spectrum of chromium (Cr II) and new radiative lifetime measurements from laser-induced fluorescence for 8 levels of Cr+ are reported. The goals of this study are to improve transition probability measurements in Cr II and reconcile solar and stellar Cr abundance values based on Cr I and Cr II lines. Eighteen spectra ...

Microstructural and electrical properties of Cu-chromium alloy (Cu-Cr) dispersed with vapor-grown carbon fiber (VGCF) prepared by powder metallurgy (P/M) process have been investigated. Cu-0.7 mass% Cr pre-alloyed powder (Cu-Cr) made by water atomization process was used as raw materials, which contained solid solute Cr elements in Cu matrix. The alloy powder coated with un-bundled VGCF by usin...

Cajal-Retzius (CR) cells are early-generated transient neurons and are important in the regulation of cortical neuronal migration and cortical laminar formation. Molecular entities characterizing the CR cell identity, however, remain largely elusive. We purified mouse cortical CR cells expressing GFP to homogeneity by fluorescence-activated cell sorting and examined a genome-wide expression pro...

The Incredible Years parent and classroom interventions were evaluated for the first time in elementary schools. Culturally diverse, socioeconomically disadvantaged schools were randomly assigned to intervention or control (CON). In intervention schools, all children received a 2-year classroom intervention beginning in kindergarten. In addition, indicated children were randomly assigned to als...
