Background: Cardiac output (CO) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. CO is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. Hence, measuring CO has always been a matter of interest to researchers and clinicians. Sev...

Objective(s): siRNA may be a very promising tool for treatment of various diseases especially in cancer therapy due to high specificity. One of the main hurdles applications of siRNAs in vivo is optimization of the delivery strategy, especially the carrier systems. The aim of this study was to optimize siRNA delivery into suspended erythroleukemic cell line K562. Materials and Methods: We appli...

We first measure attitudes toward a product and attitudes toward product quality when an unknown brand is associated with a well-known and trusted co-brand in the form of payment and delivery options; employing a classic co-branding strategy. Theory suggests that association with a trusted brand should lead to improved positive assessment of an unknown brand. Results suggest that the popular be...

Background The newly synthesized Aurora-A kinase inhibitor XY-4 is a potential anti-cancer agent, but its hydrophobicity and limited efficiency restrict further application. Nanotechnology based combined therapy provides an optimized strategy for solving these issues. Methods In this study, the newly synthesized Aurora-A kinase inhibitor XY-4 and Bcl-xl targeted siRNA were co-delivered by cat...

A healthy workforce is critical to the success of an organization or a society. Properly managing the delivery of health care is thus an important function of modern health care systems. However, health care delivery today is rife with waste and inefficiency. Kohn et al. (2000) estimated 50,000 to 100,000 lives are lost each year because of medical errors. Schoen et al. (2006) found that 42 per...

Among different non-viral gene delivery methods, the technique of co-precipitation of Ca(2+) with DNA in the presence of inorganic anions is an attractive option because of the biocompatibility and biodegradability. In this study, nano-sized CaCO(3)/DNA co-precipitates for gene delivery were prepared. The effect of Ca(2+)/CO(3)(2-) molar ratio on the gene delivery was investigated. The mechanis...

BACKGROUND Existing guidance for developing public health interventions does not provide information for researchers about how to work with intervention providers to co-produce and prototype the content and delivery of new interventions prior to evaluation. The ASSIST + Frank study aimed to adapt an existing effective peer-led smoking prevention intervention (ASSIST), integrating new content fr...

The barrier morphology of skin provides major obstacles for the application of siRNA for gene silencing, which current delivery technologies do not effectively overcome. Emerging technologies utilise microprojection array devices to penetrate into the skin epidermis and dermis for delivery of drug payloads. Delivery of siRNA by such devices has been proven in principle, yet requires optimisatio...

context biocompatible polymers are potentially effective for dental infections as delivery carriers of disinfectants or antibiotics into the root canal system (rcs). this study aimed to review polymeric microspheres enabling a controlled release of endodontic medicaments. evidence acquisition a literature search was carried out in the pubmed database (may 2013) using the following keywords: “po...
