Photo acoustic drug delivery is a technique for localized drug delivery by laser-induced hydrodynamic pressure following cavitation bubble expansion and collapse. Photoacoustic drug delivery was investigated on gelatin-based thrombus models with planar and cylindrical geometries by use of one microsecond laser pulses. Solutions of a hydrophobic dye in mineral oil permitted monitoring of deliver...

When studying diffusion weighted imaging(DWI), it is important to create a phantom that has a reliably controlled diffusion coefficient. In this study, we investigated phantoms to control both the diffusion coefficient and the T2-value by changing the concentration of gelatin or sucrose and MnCl(2), respectively. The results showed that the diffusion coefficient decreased linearly with increase...

In searching for new sources of oil, protein and gelatin researchers have investigated many wild plants, but our research group took a different approach: We looked at insects as oil, protein and gelatin source for both nutritional and industrial applications. According to Sudanese indigenous knowledge, many insects have food and medicinal uses. We targeted two of these insects for our research...

In this paper, a novel design of near-field dipole antenna sensor array for breast tumor detection is presented. The proposed consists four electrically small antennas fed by single port. Due to the proven fact that tumors have higher dielectric properties than surrounding normal tissues, utilized detecting evaluating variations sensor’s response two cases, and abnormal, tissues. A simulation s...

One of the prawn rearing method had been using artificial feed of gelatin-acacia microcapsule. Characteristics of this microcapsule is very small and its size can be predicted and its density is as same as sea water.This study aimed to measure size distribution of fish oil droplet and the gelatin-acacia membrane was calculated in order to get the same density of sea water. Results of this study...

N ATURE of the carrier is known to affect efficiency of utilization of vitamin A by several species. For humans, aqueous dispersions of vitamin A have been found superior to oil solutions for maintaining blood levels and promoting growth (Kramer, 1947; Lewis, 1947, 1950; Sobel, 1949; and their respective coworkers). Kagan et al., (1953) reported that both alcohol and ester forms in aqueous disp...

Introduction Tumor hypoxia is well known to reduce cancer treatment efficacy [1]. Hypoxic tumor cells, which have decreased oxygen levels (pO2), are more resistant to radiotherapy and chemotherapy. Dissolved oxygen influences the F magnetic resonance relaxation times of perfluorocarbons [2]. This property has been used in semiquantitative animal studies to image tumor oxygenation [3]. In this s...

The microencapsulation of tuna oil in gelatin-sodium hexametaphosphate (SHMP) using complex coacervation was optimised for the stabilisation of omega-3 oils, for use as a functional food ingredient. Firstly, oil stability was optimised by comparing the accelerated stability of tuna oil in the presence of various commercial antioxidants, using a Rancimat™. Then zeta-potential (mV), turbidity and...

A set of three cubic one-litre phantoms containing spherical simulated lesions was produced for use in comparing lesion detection performance of different elastography systems. The materials employed are known to be stable in heterogeneous configurations regarding geometry and elastic contrast identical with (storage modulus of lesion material) / (storage modulus of background material), and re...

results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...
