A tissue-like gelatin elasticity-flow phantom was examined to develop ultrasonic strain imaging for the detection of internal pulsatile deformations. The same imaging technique was then applied in vivo to monitor deformation in tissues surrounding the normal brachial artery. The results suggest that vascular strain patterns resulting from biologic stimuli are very different from those generated...

angelica essential oil (ao), a major pharmacologically active component of angelica sinensis (oliv.) diels, possesses hemogenesis, analgesic activities and sedative effect. the application of ao in pharmaceutical systems had been limited because of its low oxidative stability. the ao-loaded gelatin-chitosan microcapsules with prevention from oxidation were developed and optimized using response...

We present the experimental results for scattering intensity which arises from illumination of turbid medium with laser light for characterizing the different types of particles. The imaging of tissue like phantom provides the possibility of modeling the laser tissue interaction parameters for the diagnostic of malignant disease and determining the optical properties of a material. Analytical m...

We report the spontaneous patterning of polymer microgels by confining a polymer blend within microspheres. A poly(ethylene glycol) (PEG) and gelatin solution was confined inside water-in-oil (W/O) microdroplets coated with a layer of zwitterionic lipids: dioleoylphosphatidylethanolamine (PE) and dioleoylphosphatidylcholine (PC). The droplet confinement affected the kinetics of the phase separa...

Aspergillus niger (A. niger) is a common species of Aspergillus molds. Cutaneous aspergillosis usually occurs in skin sites near intravenous injection and approximately 6% of cutaneous aspergillosis cases which do not involve burn or HIV-infected patients are caused by A. niger. Biomaterials and biopharmaceuticals produced from microparticle-based drug delivery systems have received much attent...

AIM Precise targeting is essential for adequate treatment of lesions during image-guided therapy. The aim of this study was to compare the performance of two emerging image-guided targeting technologies in a phantom model. MATERIALS AND METHODS A computer-assisted navigation system and AcuBot were tested using three operators: an interventional radiologist and two endourologists. Fiducials we...

Removal of the highest amount albumin and IgG in blood plasma for determination disease-specific proteins is great importance field diagnosis treatment. In this study it aimed to prepare biosorbent be used as a support material affinity chromatography. Gelatin biosorbents were prepared by water oil emulsion method stabilized with glutaraldehyde biofunctional crosslinker obtain spherical biosorb...

BACKGROUND Echocardiography is the method of choice when one wishes to examine myocardial function. Qualitative assessment of the 2D grey scale images obtained is subjective, and objective methods are required. Speckle Tracking Ultrasound is an emerging technology, offering an objective mean of quantifying left ventricular wall motion. However, before a new ultrasound technology can be adopted ...
