The preparation of single-cell suspensions from tissues is an important prerequisite for many experiments in cellular research. The process of dissociating whole organs requires specific parameters in order to obtain a high number of viable cells in a reproducible manner. The gentleMACS Dissociator optimizes this task with a simple, practical protocol. The instrument contains pre-programmed set...

This work reports the preparation of molecularly imprinted polymer (MIP) particles for selective extraction and determination of silver ions from aqueous media. Various parameters were optimized, such as pH, time, concentration of sample and type of eluent for elution of silver from polymer. Also Interfering effect was investigated on the absorption of silver by molecularly imprinted polymer. A...

In support of threat evaluation stage of Intelligence Preparation of the Battlefield (IPB) for asymmetric opponents, we are developing a modeling and metrics framework to: • predict the emergent coordination or disruption of activity in social systems models that i. employ regulating feedback, often construed as violence, as a means of achieving goals, and ii. use learning (evolutionary and/or ...

Chemical exchange between water and labile protons from amino-acids, proteins and other molecules can be exploited to provide tissue contrast with magnetic resonance imaging (MRI) techniques. Using an off-resonance Spin-Locking (SL) scheme for signal preparation is advantageous because the image contrast can be tuned to specific exchange rates by adjusting SL pulse parameters. While the amide-p...

This work aimed to prepare a nanoemulsion preparation containing budesonide and assess its aerodynamic behavior in comparison with suspension of budesonide. In-vitro aerodynamic performance of the corresponding micellar solution (ie. nanoemulsion preparation without oil) was investigated too. Nanoemulsions of almond oil containing budesonide, as a hydrophobic model drug molecule, were prepared ...

background and objectives: colocynthin is the major active secondary metabolite of colocynth, citrullus colocynthis (l.) schrad, which has been used in traditional and ethno medicine of many countries.  it could be considered as an active marker for quality control of colocynth and its herbal products. analysis and standardization of colocynth and its herbal preparations are a critical issue fo...

BACKGROUND The analysis of angiogenesis factors in the blood of tumor patients has given diverse results on their prognostic or predictive value. Since mediators of angiogenesis are stored in platelets, their measurement in plasma is sensitive to inadvertent platelet activation during blood processing. METHODS Variants of blood withdrawal and plasma preparation were evaluated by ELISA for the...

This work reports a facile sonochemical route in the synthesis of nano particle of deferasirox for the first time. One application of nanotechnology is in improvement of available treatments for various diseases. Deferasirox (ICL670 or Exjade) is a tridentate chelating agent for removing transfusion overload iron in thalassemia patients. In the present work, deferasirox was prepared in nano size...
