Optical-computed tomography (CT) and optical-emission computed tomography (ECT) are recent techniques with potential for high-resolution multi-faceted 3D imaging of the structure and function in unsectioned tissue samples up to 1-4 cc. Quantitative imaging of 3D fluorophore distribution (e.g. GFP) using optical-ECT is challenging due to attenuation present within the sample. Uncorrected reconst...

Introduction: Geometric distortion, an important parameter in neurology and oncology. The current study aimed to design and construct a new three-dimensional (3D) phantom using a 3D printer in order to measure geometric distortion and its 3D reproducibility. Material and Methods: In this study, a new phantom ...

The response of thin polymer gel cassettes (called NIPAM gels) to ionizing radiation was investigated in this study. The NIPAM gels were prepared from gelatin, N-isopropyl acrylamide, tetrakis (hydroxymethyl) phosphoniumchloride, and N,N'-methylene-bis-acrylamide. Gel cassettes were irradiated in a phantom using a linear accelerator, and the polymerization morphology of irradiated NIPAM gel was...

The aims of this study were to report for the first time, the extraction and physico-chemical properties of chicken skin gelatin compared to bovine gelatin. Extracted chicken skin gelatin 6.67 % (w/v) had a higher bloom value (355 ± 1.48 g) than bovine gelatin (259 ± 0.71 g). The dynamic viscoelastic profile of chicken gelatin exhibited higher viscous and elastic modulus values compared to bovi...

Biodegradable materials decompose and return to nature. This functionality can be applied derive robotic systems that are environmentally friendly. study presents a fully biodegradable soft actuator, which is one of the key elements in “green” robotics. The working actuator based on an electrohydraulic principle, similar hydraulically amplified self-healing electrostatic actuators. developed th...

Introduction: In the last 28 years, the scientific community has been using elastography to evaluate the mechanical properties of biological tissue. The aim of this work was the optimization of the UDmV method, presented in Part I of the series, by means of modifying the technique employed to generate the reference sine and cosine functions, used for phase-quadrature demodulation, and determini...

To the Editor, Ultrasound-guided catheterization is an essential skill for central venous catheterization and difficult peripheral vascular access. Compared with landmark techniques, it is associated with higher rates of successful cannulation and fewer complications. Safe, effective use of ultrasound, however, requires operator skill. Trainees must develop the dexterity needed to manipulate th...

Abstract Essential oils containing volatile aromatic compounds generally have the ability as antioxidants and antibacterial. By nature, they are easily degraded because of oxygen, light, high temperatures, so need to be encapsulated. This study aimed analyze effect type essential combination coating materials on physicochemical characteristics oil microcapsules. used a Randomized Block Design m...

Abstract The k-Nearest Neighbor (KNN) algorithm was used to classify and select biodegradable packaging produced from fish gelatine incorporated with palm oil clove oregano essential oils. All reinforced films are highly resistant attraction, an emphasis on a sample of value 53.18 MPa. Also, the addition oils increases elasticity thickness packages. packages have antioxidant antimicrobial prope...
