The paper presents initial experiments on a basic forward engineered childbirth simulator. Polygonal models of a fetal skull and bony maternal pelvis were created. A simple physics model was implemented to model the mechanical contact interaction between the fetal head and the maternal pelvis. A series of experiments were run to establish whether this basic model would display the cardinal movements...
Texture features are very popular and widely-used in many image processing and computer vision applications. Mathematical morphology offers a series of tools for texture description, like granulometry and morphological covariance. However, there are few methods for color texture description through morphological approaches, due to the issues arisen at the extension of the morphological operations...
Ability to project cancer incidences and mortality is very important for cancer research and healthcare planning and is also a vital part of cancer screening and management programs. In current years, machine learning algorithms have been successfully shown to generate high forecasting accuracy and have drawn interest from healthcare professionals, research community, planners and policy makers. In...
The use of digital image processing as a medical diagnosis aid is now well established, being slowly but successfully integrated directly within the medical imaging devices. The traditional use of digital image processing as a post-imaging technique is still interesting, especially for new approaches to classical applications or for pioneering new ones. Our studies in the field of near automatic interpretation...
Local Binary Pattern (LBP) is an effective method for texture analysis, being appreciated for accuracy and computing power. The LBP operator is invariant to illumination and contrast changes in the image. Intensity Histogram is a simple method used to compare images with the advantage of being insensitive to small changes of camera position. The biggest disadvantage for this technique is that it provides...
Chronic obstructive pulmonary disease (COPD) currently occupies sixth place in the list of morbidity causes in the world adult population and is catching third in 2020; smoking is the most important cause. COPD mortality reaches 200–300%ooo for the age group 45–64 years, 6% of deaths in men and 4% of deaths in women. Mortality from the disease is increasing at 3rd place in 2020, the disease having...
Smoking is a major public health problem with medical, social, and financial implications. We conducted a retrospective analysis of data resulting from enrollment and completion of a smoking cessation program of a number of 399 subjects of both gender, who presented consecutively in 2009 to the Smoking Cessation Counseling Medical Office of the Iasi Clinical Rehabilitation Hospital. The treatment...
The growth of micro-organisms on a culture medium for the biosynthesis of products is the process of interaction of the individual cell and culture medium. Applying the laws of thermodynamics and mass transfer and energy demonstrates that culture of microorganisms is influenced directly the temperature, pH and concentration of substrate. Implementation of monitoring and management favorable methods...
Patients with acromegaly are reported to have a 1.6 to 3.3 fold increase in the mortality rate and a 10-year reduction in their lifespan. Sleep apnea is considered the most common respiratory complication in acromegaly. The aim of our study was to evaluate the severity of sleep apnea, and its particularities, in patients with acromegaly in Cluj-Napoca, Romania. We investigated 35 patients with acromegaly,...
Nowadays the main problems of ultrasound imaging (USI) are the quality of the image (in terms of signal-to-noise ratio and resolution) and the duration of data acquisition. For solving these challenges, multiple methods were studied during the last decade. It was shown that through the transmission of coded excitation pulses to the ultrasound probe, we can obtain an enhancement of signal-to-noise...
Schizophrenia as severe mental disorder is characterized by a disintegration of the process of thinking and of emotional responsiveness whereas the underlying mechanisms of schizophrenia are complex and still discussed. The objective of this study is to find out if patients with schizophrenia and their healthy first-degree relatives have abnormal autonomic nervous system (ANS) activity by measuring...
Emerging x-ray breast imaging applications require the use of realistic physical three-dimensional phantoms are breast CT, phase-contrast mammography and the existing breast Tomosynthesis, dedicated to screen as early as possible and diagnose cancer in breast. However, manufacturing of such phantoms meets difficulties related to the current technology, suitable materials, manufacturing precision,...
Functionalized superparamagnetic nanoparticles based on poly (succinimide)- b -poly(ethylene glycol) and magnetite have been obtained by immobilization of superoxide dismutase via activation with 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide hydrochloride (EDAC). Dynamic light scattering measurements showed that hydrodynamic mean diameters of the functionalized particles were about 700 nm. These...
Gradient forces formed by speckle structures in laser-irradiated biological tissue are studied. Speckle fields and some their parameters, such as speckle sizes, are theoretically evaluated. Multi-layered human skin is taken as biotissue. The gradients of light intensity at varying depths inside the tissue are estimated. It turned out that to provide the maximal force acting on a biological particle...
The paper addresses two issues: the definition of a Global Activity (GlA) index for the physical activity of persons, and the development of a sensor on textile substrate and of the related front end circuitry for destined to health monitoring. Preliminary experimental results are reported.
The gas flow is the main parameter for pulmonary ventilation. Gas flow and flow direction control and monitoring are essential for inspiratory and expiratory tidal volume and the minute volume required values and determination, for determining the inhale-exhale patient system leakage and others.
The study conducted on a lot of 3 people aimed to highlight the effects upon the human body of a dose of electro colloidal silver (ECS) within more than 5 hours after ingestion by repeated measurements with a GDV (Gas Discharge Visualization) Camera. The results were processed and rendered graphically to allow verify the empirical hypotheses about these effects and draw some preliminary conclusions...
This study investigates a concentric bipolar active (CBA) electrode with ultra-high input impedance for noninvasive measurement of biopotentials from the autonomic nervous system (ANS). Experiments involving Valsalva maneuvers (VM) conducted with 4 male subjects showed spike-like potentials that resembled neural potentials recorded directly with microelectrodes from autonomic nerve. Spike-like bursts...
The objective was to find a way for analyzing the medical x-ray images using fuzzy inference systems in order to confirm the presence of osteosclerosis in the bone sections of the joints of the hand and the knee. The medical x-ray is segmented in order to separate the bone sections from the background. The histogram of the bone sections with the metadata extracted from the medical x-ray is analyzed...
Medical practice is more and more based on electronic healthcare records. Big data and great amount of information drive medical staff to use decision support software to support their activities. The paper presents a software solution in this area, collecting a set of successful treatments from diverse medical software, based on tested treatments related to illness that makes suggestions to other...
