Attention deficit hyperactivity disorder (ADHD) is a mental disorder that affects millions of children. It is difficult to diagnose because symptoms of ADHD differ from person to person. The aim of this study is to develop an objective tool that can help physicians to diagnose this disease by minimizing the human effort. Brain MR images from 26 individuals from NP Istanbul Neuropsychiatry Hospital...
Since, the amplitude information of EEG signals are very small, during the detection process of EEG signals lower noise components are important for preventing of data loss. The first time of data loss is detection process of EEG signals from the patient. So any improvement over this process increases the quality of signals. Because of that electrode which is providing the connection between patient...
Hookah Smoking results to escalation in premature beats of the ventricles, which tend to be a leading risk factor that results to sudden cardiac death (SCA). Hookah smokers tend to be at high risk for cardiovascular diseases due to tobacco consumption from a hookah device. The primary objective of this research is to analyze immediate consequences of hookah smoking on ECG. A secondary aim is to compare...
In this study, it was aimed to detect lesion and their radius information from mammography images using the Vision Development Module. The study was performed using ten different images with uniformly distributed lesions from the mammography images found in the MIAS database. First, threshold was applied to the mammography images loaded into the Vision Development Module to make the lesions clear...
EOG (Electrooculogram) is the measurement of the electrical activity of the eye movements with the surface electrodes from the eye region. In this study, a dualchannel computer-based EOG meter was developed for the detection of EOG signals. An attention test software was developed to provide an analysis of eye movements during signal processing, and the reference directions on the test were determined...
Patient portal is a website that provides patients a safe and secured access to their personal health information and offers some significant functionality. This paper proposes an outline for the future of the health care services in the UAE which will introduce a new level of health care to encourage operational and human effort savings. This is accomplished by proposing a framework which adopts...
Pseudomonas aeruginosa strains (P. aeruginosa), which is a type of gram-negative bacteria can cause infection in many parts of the body. Strains of P. aeruginosa have become resistant because of misusing and abusing of antibiotics. As bactericide resistance to antibiotics makes treatment difficult, this has led to the research for alternative treatment methods. Photodynamic Therapy (PDT) is an alternative...
Electrospinning is a bio-fabrication method, which helps to produce highly interconnected nano-porous structure with a high surface to volume ratio by using polymer solutions. In tissue engineering applications, scaffolds composed of electrospun nanofibers are produced from synthetic polymers to resemble specific tissue. Most of synthetic polymers has high hydrophobicity since the nonpolar groups...
Vascular scaffolds produced by bio-fabrication methods can provide ideal conditions for attachment and proliferation of ECs (endothelial cells). But these grafts might not allow migration of cells into the scaffold. Therefore, scaffolds, which resembles ECMs (extracellular matrix) should produce by changing scaffold size and shape. The diameter of nanofibers can be controlled by using electrospinning...
Advanced smart pillboxes are needed for use with the heart rate regulating drugs. The most important component of these pillboxes is the heart beat rate sensor. In this study, experimental analyses have been performed with different optical sensors namely HRM-2511B transmissive sensor, TCRT1000 reflective sensor and PulseSensor reflective sensor in heartbeat sensing. All of the sensors provide very...
Studies about improving of health quality conditions of handicapped members is getting increase. Internet become one of the important part of human life in todays. Accessibility is a term that determine of using systems and product by everyone. Our aim in this study to determine difficulties of handicapped persons to use internet and smart phone. According to results of the study, handicapped persons...
In this study, heartbeat signals were acquired by an oscillometric based measurement system. Oscillations that occur during the heartbeat are detected by a pressure sensor and oscillation signals which contain this heartbeat information are transmitted to the computer via arduino. To validate this oscillometric based system ECG signal acquisition was performed simultaneously by Biopac MP36 measurement...
Electrocardiogram (ECG) is the process of recording the electrical activity of the heart with help of the electrodes placed on the skin surface. ECG recordings are one of the most useful tools used to diagnose heart diseases. In this study reference circuit design which produces ECG signal was performed. Signals which are simulated were sampled and the calculated values were converted into pulse width...
Calcium phosphate materials are used as cements, composites and coatings in many medical and dental applications due to their similarity to bone both in composition and in osteoconductive and osteoactive properties. Injectable cement is used in hard tissue repair as an adjunct to internal fixation of fractures. In this study, we experimented with the production and characterization of Ca-P and silk...
One of the difficulties in implementing family medicine is the number of people per physician. This large number of enrollees makes preventive health services unavailable due to forcing physicians to do only outpatient services. In this study, it is aimed to realize the Family Physician Monitoring S ystem which will enable early intervention to the diseases that may occur by watching realtime medical...
“Diabetes Mellitus (Diabetes)” is a disease based on insulin hormone disorders secreted from the pancreas gland. Clinical findings find out that diabetes causes some diseases in vital organs. “Diabetic Retinopathy” is one of the most common eye diseases based on diabetes, and it is the leading cause of visual loss resulting from structural changes in the retinal vessels. Recent researches show that...
Ethics committee approval processes in development of medical devices begin with request to obtain CE certificate of medical devices that are classified under the Medical Device Directive. In accordance with the Medical Devices Clinical Research Directive, it is necessary to obtain the approval to test on volunteers with medical devices, which is non-CE marked or similar devices that are not found...
With regard to electrical interactions in the brain, Electroencephalographic (EEG) records are strongly considered to be one of the most applicable methods in diagnosis of neurologic diseases. One of the neurologic diseases is called Epilepsy which has impacted uponnearly 1% of the population worldwide. Today, employing computerized systems, to use in quick diagnosis of illnesses that has been a paramount...
In this paper, the effects of autapse (a kind of synapse formed between the axon or soma of a neuron and its own dendrites) on the weak signal detection capacity of a Hodgkin-Huxley (H-H) neuron are investigated. In the study, we consider that the H-H neuron has an inhibitory autapse modeled as a chemical synapse. The subthreshold sine wave is injected to the H-H neuron as a weak signal. Obtained...
Plasma is the fourth state of matter. For long time plasma has been used in several areas of science. Moreover, plasma in medicine has a huge area from wound healing to sterilization of medical equipment. One of the most promising applications of cold plasma is on wound healing. The aim of this study is to develop a portable atmospheric cold plasma device for infected wound management. This study...
