BACKGROUND This study investigated the frequency of patients with HCC who refused cancer-directed surgery and the characteristics and outcomes of these patients. PATIENTS AND METHODS A retrospective study was performed using data from the Surveillance, Epidemiology, and End RESULTS (SEER) Program. Characteristics of patients who refused CDS were compared with those who accepted surgery using ...

A review is presented on the use of charged cyclodextrins (CDs) as chiral selectors in capillary electrophoresis (CE) for the separation of analytes in pharmaceutical analysis. An overview is given of theoretical models that have been developed for a better prediction of the enantiomeric resolution and for a better understanding of the separation mechanism. Several types of charged CDs have bee...

The main goal of this work was to synthesize CdSe/CdS (core-shell) nanoparticles stabilized by polymer ligand using entirely aqueous colloidal chemistry at room temperature. First, the CdSe core was prepared using precursors and acid-functionalized poly(vinyl alcohol) as the capping ligand. Next, a CdS shell was grown onto the CdSe core via the layer-by-layer technique. The CdS shell was formed...

OBJECTIVES To develop a valid and reliable instrument to assess caregiver burden in caregivers of children with cerebral palsy (CP). METHODS A self-administered, multidimensional instrument--Caregiver Difficulties Scale (CDS)--was developed using a combined qualitative-quantitative approach. Items for the preliminary draft were selected from existing caregiver assessment instruments by consen...

the aim of this study was to design interpretative structural model (ism) of the components of sport diplomacy. the present study was applied in terms of aims and descriptive with regard to data collection. with review of related literature and qualitative interviews (content analysis) with 13 iranian and foreign experts of sport diplomacy, components and items of sport diplomacy were identifie...

Carbon dots (CDs) have been widely studied since their discovery in 2004 as a green substitute of the traditional quantum dots due to their excellent photoluminescence (PL) and high biocompatibility. Meanwhile, polymers have increasingly become an important component for both synthesis and modification of CDs to provide polymeric matrix and enhance their PL property. Furthermore, critical analy...

OBJECTIVE To review the literature on clinical decision support (CDS) for genetically guided personalized medicine (GPM). MATERIALS AND METHODS MEDLINE and Embase were searched from 1990 to 2011. The manuscripts included were summarized, and notable themes and trends were identified. RESULTS Following a screening of 3416 articles, 38 primary research articles were identified. Focal areas of...

An efficient photocatalyst consisting of CdS nanoparticle dispersed mesoporous silica-titania was prepared using amphiphilic triblock copolymer P123 as template and silica-titania sol–gel precursors. The CdS nanoparticle was incorporated into silica-titania mesoporous nanosturctures by post impregnation method. The synthesized catalyst has been characterized by FTIR, TEM, SEM, and EDAX analysis...

The toxic effects of CDs on rare minnow (Gobiocypris rarus) embryos at different developmental stages were investigated. The results showed that rare minnow embryos had decreased spontaneous movements, body length, increased heart rate, pericardial edema, yolk sac edema, tail/spinal curvature, various morphological malformations, and decreased hatching rate. Biochemical analysis showed the CDs ...

BACKGROUND The Cardiac Depression Scale (CDS) has been designed to measure depressive symptoms in patients with heart disease. There is no Arabic version of the CDS. We translated and validated the CDS in an Arabic sample of patients with heart disease. METHODS Forward and back translation of the CDS was followed by assessment of cultural relevance and content validity. The Arabic version of ...
