The study aimed to investigate and compare characteristics of Bombyx mori silk film coated with mimicked re-self assembly collagen type I under various conditions concentration [0.25,0.5,1.0,2.0 mg/ml]. The thin films consist of collagen fibrils and result from the self-assembly of collagen. The morphological characteristics observed by scanning electron microscopy (SEM) showed that when increased...
A novel co-culture device of neuronal cells was developed for analysis of cell interaction between a normal cell and an Alzheimer's disease infected cell. The device consisted of co-culture chamber system and a microelectrode arrays(MEA). The chamber system has a central chamber and three peripheral compartment chambers, connected by micro-channels. Rat hippocampal neurons were cultured separately...
The ECG is a method for the detection of cardiovascular disease is simple and effective. The ECG. Check that the electricity produced on the heart muscle, cardiac compression. At the point where the heart muscle cells that can create a special type of electricity itself. We call this point that Sinus node electrical current to run through the muscles of the head room on the power that we have called...
This study was conducted to statistically recognize the walking, jogging, and running activities by using accelerometers build-in a smartphone. Using the smartphone causes the user need not to carry another device more. The advantage of the study is to observe remotely any movement of an interested person at all time so the observer can manage appropriate program for exercise, monitor energy consumption,...
Drug concentrations in blood are good indexes for drug thearpy. This study proposed an approach based on Raman spectroscopy of tears for a rapid and minimally invasive monitoring of the concentration. Tear fluid reflects the drug concentration in blood and its collection can be performed easily and noninvasively in comparison to blood drawing. Raman spectroscopy is a rapid and sensitive analytical...
Left ventricular assist devices (LVADs) have confident in treatment for end-stage heart failure. The mainly development of LVADs design based on a rotary blood pump (RBP) technology for both long-term and short-term supports. The first generation of LVADs was the pulsatile system based on volume displacement technology. For the second generation of LVADs, novel LVADs were developed to be a non-pulsatile...
Recent researches have demonstrated implications of Arterial Pulse analysis from Radial and Brachial artery on cardiovascular, renal and autonomic nervous system, as early indicator of major ailments. We have developed a low-cost Arterial Pulse Analyzer which provides run-time display of Arterial Pulse waveforms during the test as well as provides analysis of the waveforms in digitally storable format...
This paper presents a concept of the design and development of an infant incubator by increasing a number of an air flow slot for air-inlet and air-outlet inside a double wall infant incubator. The number of airflow inlet slot is increase to 2 while an airflow outlet slot is to 4 at the lateral side. The study is done by using FEM simulation to compare between single air flow slot and multi air flow...
This paper presents an analysis of heat transfer from the surrounding area skin of newborn under using infant radiant warmer (IRW) by finite element three-dimensional software. And to compare the results of heat transfer measurements from experiments on the IRW in used everywhere. In this study, results are obtained for a simplified model. It is equipped with. Systems design, the properties of materials...
The blood test is a routine procedure in medical diagnosis. However it takes a couple of days to get the results because blood samples are analyzed by sending to the specialized facility because the operation of the blood test instrument is costly for a hospital or clinic. So development of a novel low cost blood test device is an important issue considering the burden of the patient. To developing...
This study presents a simple fabrication of polymeric diaphragm pressure sensors by embedding a commercial thin-film strain gauge in a polymeric diaphragm. Two different polymer materials, polydimethylsiloxane (PDMS) and polyethylene terephthalate (PET), were employed for fabrication. Performance of pressure sensors fabricated with two different polymers including sensitivity, linearity, and long-term...
Beamforming the ultrasound radiofrequency (RF) data on the computer in stead of doing it on the hardware is currently developed in many research groups. This requires fast transferring of the large amount of data in real-time from the ultrasound scanner front end to the computer. Despite of using an expensive hardware for fast data transfer, we are interested in compress the data before transferring...
This study focused on the step of preprocessing in the part of edge detection techniques to detect red blood cells (RBCs) boundaries. The objectives of the study were to make a comparison between gradient based edge detection and zero-crossing based edge detection and to find out the appropriate operator to use for edge detection of RBCs in capillary. Sobel, Robert, Prewitt and Canny were used as...
Many different types of biomedical data can be recorded, however not every method of interpreting this is equally applicable for comparison within or between test groups. When comparing related but dissimilar group members sometimes it is necessary to use alternative methods of analysis, potentially with data derived from the originally recorded data. This paper outlines one such method that was used...
In dentistry, often dental radiography is related to teeth occlusal surface, which can be used for diagnostic and treatment purposes. Nonetheless the exposure of X-Ray dose may limit the usage of this technique. This paper presents the image construction from the occlusal surface of human teeth. The principle of the surface construction is from the exploitation of reflected light intensities along...
A novel technique to analyze propagation of fluid flow pattern based on magnetic resonance (MR) velocimetry has been developed and applied to cerebrospinal fluid (CSF) dynamics in intracranial space. This technique evaluates spatial distribution of the correlation time as well as correlation coefficient of velocity waveform with respect to an arbitrary reference waveform using quantitative velocity...
This study proposes and appraise a gray level co-occurrence matrix (GLCM) for extracting the feature of cell regions in microscopic image into four region types: positive cancer cell, negative cancer cell, lymphocyte and stromal cell. The classification task uses decision tree with cross validation. To give a high classification performance, the main focus of interest is feature extraction task. Twenty-two...
The Hospital Drug Information Center (DIC) is an essential unit in a hospital, providing critical information to support clinical services for virtually every department in the facility. Current hospital information systems (HIS) have not provided adequate functionality to support the services of the DIC, which are primarily focused on documentation and reporting. The software described here represents...
This study proposes and evaluates a neural network (NN) classifier for dividing the histological structures (HS) in breast cancer (BC) microscopic image into two region types: cancer or normal. Cancer region included positive cells and negative cells while normal region included stromal cells and lymphocyte. The classification task using a back propagation learning algorithm is applied to the multilayer...
The improvement of heart function are the important consideration for heart failure patient with rotary blood pump (RBP). The capable of function evaluation depend on good monitoring system, which facilitate the physician for diagnosis. In this study, pressure estimation from measured flow rate for the patients with external RBP support is implemented with the non-invasive technique for cardiac function...
