Introduction Proton resonance frequency shift (PRFS) thermometry of the breast is often confounded not only by the presence of fat in the tissue but also by respiration-induced B0 changes even in the absence of detectable breast motion. We (and others) have measured B0 changes of up to 0.16ppm due to respiration[1] leading to temperature errors on the order of 16°C (due to the 0.01ppm/°C PRFS s...

In this work, crosslinkers were prepared by conjugating high- and low-molecular-weight gelatin with different mole ratios of itaconic acid (IA) with double bonds. Then, the gelatin-itaconic acid (gelatin-IA) crosslinkers were compared with the gelatin-methacrylate (gelatin-MA) crosslinkers. The molecular weights and structures of gelatin-MA and gelatin-IA were confirmed using gel permeation chr...

One of the mainly popular consumed colloid protein materials in pharmaceutics, medical, food and military industries is Gelatin. Especially from warm-water fish gelatin report poss similar characteristics to mammalian’s gelatin .Yellow fin tuna (Thunnus albacares) gelatin skin, lots of waste in form of skin and bones of the fish are produced every day. Analysis factors were extracted alkaline g...

Gelatin was extracted from hydrolyses of collagen muscle bonds. Gelatin was of two types. Type A was obtained from acidic and type B from alkaline procedures. In the present study we used sturgeon fish skin to produce 25 samples of gelatin. Microbiological and chemical examinations were conducted on the gelatin samples. Based on the results obtained from the chemical examination, gelatin type A...

  Introduction: Geometric distortion is a major shortcoming of magnetic resonance imaging (MRI), which has an important influence on the accuracy of volumetric measurements, an important parameter in neurology and oncology. Our goal is to design and construct a new three- dimensional phantom using a 3D printer in order to measure geometric distortion and its reproducibility in...

BACKGROUND: Assessment of quantitative parameters using magnetic resonance imaging (MRI) is a relevant trend. Fat fraction (FF) calculation provides new opportunities for accurate diagnosis and will replace invasive methods such as biopsy in the future. Quantification enable reliable dynamic monitoring assessment drug therapy. However, radiologists clinical specialists must be confident accurac...

In a preliminary statement the writer (1) presented the proposition that the minimum physical properties of gelatin (conductivity, osmotic pressure, viscosity, maximum opacity) which are usually thought to define its isoelectric point are propert’ies of pure gelatin, and that pure gelatin is not isoelectric; that pure gelatin from lime-conditioned stock is a weak acid which in an electrical fie...

in this study, the effect of gelatin-chitosan edible coating on the quality of chicken breast during 9 days of refrigerated storage (4 was investigated. three concentrations of gelatin (3, 6 and 8% w/v) and two concentrations of chitosan (1 and 2% w/v) were used to prepare the coating materials. samples was divided in 7 group, no coating (control), gelatin 3% and chitosan 1% (sample 2), gelatin...

Consumption of food products derived from porcine sources is strictly prohibited in Islam. Gelatin, mostly derived from bovine and porcine sources, has many applications in the food and pharmaceutical industries. To ensure that food products comply with halal regulations, development of valid and reliable analytical methods is very much required. In this study, a species-specific polymerase cha...
