Comorbidities and risk factors for COVID-19 in a group of Iraqi patients confirmed by real-time PCR test
Get PDFThe aim of the study was to identify characteristic risk factors predisposing to coronavirus disease 2019 (COVID-19) outbreak in a group of Iraqi patients in Baghdad City. In this study, we included a total of 13411 persons who had been tested for COVID-19, supervised by Al-Razi Medical Center in Baghdad City during the period from June 20 to November 13, 2020. Cases were tested and divided into two groups according to the result of real-time RT-PCR test for COVID-19. A total of 1781 positive cases were detected with confirmed COVID-19. Comorbidities in the study patients were identified as hypertension, diabetes mellitus and respiratory disorders. Hypertension was the most common comorbidity in COVID-19 patients followed by diabetes mellitus. The results of this study showed that patients with comorbidities were significantly associated with positive RT-PCR results related to COVID-19. It was concluded that understanding the comorbidities enhance defining patients with COVID-19 at higher risk. Further research is needed to confirm and clarify the impact of the association of co-morbidities that accompany COVID-19
Vitexin Anew Antihypertensive Drug (Isolated from prosopis farcta [Iraq endogenus] plants)
Get PDFVitexin was isolated and identified from pods of prosopis farcta (Iraqi endogenous). In vitro and in vivo cardiovascular actions of vitexin were studied. Vitexin produced positive inotropic effect which was not related to B1 adrenergic receptor activation. Vitexin has a vasodilator activities and it could reverse thevasoconstrictor response of isolated pulmonary artery to potassium chloride and phenylphrine. Vitexin has produced a significant increase in ejection fraction in volunteers with mild heart failure. Also vitexin has produced a significant increase in urinary flow and urinary sodium and potassium excretions in healthy and mild hypertensive volunteers, it’s significantly reduced mean arterial blood pressure of the mild hypertensive volunteers. The positive inotropic effect of vitexin is most properly related to the inhibition of phosphodiesterase enzyme by vitexin. The vasodilator activities of vitexin could be mostly associated to the increase in cGMP (attributed to phosphodiesterase inhibitory effect of vitexin) and the activation of K+-channels. The diuretic effects of vitexin could be attributed to the inhibition of Na-Cl symporter system in the renal distal tubule. The most likely mechanisms of action of vitexin as a hypotensive compound are through its vasodilator and diuretic effects. So this agent could be a best new antihypertensive drug compared with present antihypertensive drugs which are in the market now. In addition to that vitexin can be used in heart failure as cardiotonic dru

Precise voltage control, power sharing for DC-bus with hybrid energy storage and (Neuro-Fuzzy) controller based MPPT for Hybrid Renewable Energy
Get PDFThe main objective of this work is to design and simulation of the stand-alone Hybrid Renewable Energy system (HRES), separated from the main local network, the effect of super capacitors when connected to the system, and the effect of power source control system on the response and work of super capacitors. It consists of Photovoltaic, Wind turbine, Hybrid Energy Storage System (HESS). The HESS system consist of Batteries, Supper capacitors, with chargers. The proposed system used real record of weather pattern and load conditions for Al-Mahmoudiya Hospital. The variable sources are changing with different weather conditions. Being important energy sources for generating electricity directly from the sun. In order to generate electrical energy that is sustainable and reliable, highly efficient, low cost, and continuous. It can provide maximum power use. The absence of winds in most regions of Iraq permanently led to the use of such a type of renewable energy (RE) system called solar updraft tower (SUT). The wind turbine can be fixed inside the chimney of the SUT, to make the turbine run smoothly and continuously. Each of the HRES parts is controlled by a converter specific to each source due to the nature of the nonlinear source work. In this paper, the main sources of energy are photovoltaic panels and SUT. Finally, MATLAB program using real recorded data, the system work at a high efficiency of 98%. So the simulation results show the HRES system have excellent results and fast tracking to supply the load demand
Endometrial biopsy is an important diagnostic tool for the evaluation of abnormal uterine bleeding
Get PDFIn this study 100 biopsies were taken from the endometrium of childbearing women (18-50 yrs. of age) suffering from abnormal vaginal bleeding from Jan 2019-Dec 2019. Endometrial Biopsy (EB) is safe, an outpatient procedure, low cost, carries out without general anesthesia & the incidence of hemorrhage, infection & uterine perforation are less common than with D&C. EB is an alternative to dilatation & curette (D&C) for the evaluation of infertile & abnormal vaginal bleeding or dysmenorrheic patients. There are two main groups of causes to irregular vaginal bleeding. 1. Organic disease (74% of the cases), in this group there are obvious lesion such as, endometrial polyp, endometrial hyperplasia & chronic endometritis. The most common cause was endometrial hyperplasia 48%, it is commonly seen during the perimenopausal period (40-50yr). Less common causes include chronic endometritis 8%, hydatidiform mole 7%, and endometrial polyp 7%. 2. non-organic disease comprises 19% of all cases, anovulatory period 13% or Luteal phase insufficiency 6%. They are commonly seen from age of 18-40yrs. 6% of the cases found to have normal endometrium. 5 endometrial biopsies were inadequate & unsatisfactory for histopathological interpretation. The aim of this study is to evaluate the usefulness & disadvantages of EB & to compare it with the traditional method of endometrial curette

Computation of Wavelet and Multiwavelet Transforms Using Fast Fourier Transform
Get PDFA novel fast and efficient algorithm was proposed that uses the Fast Fourier Transform (FFT) as a tool to compute the Discrete Wavelet Transform (DWT) and Discrete Multiwavelet Transform. The Haar Wavelet Transform and the GHM system are shown to be a special case of the proposed algorithm, where the discrete linear convolution will adapt to achieve the desired approximation and detail coefficients. Assuming that no intermediate coefficients are canceled and no approximations are made, the algorithm will give the exact solution. Hence the proposed algorithm provides an efficient complexity verses accuracy tradeoff. The main advantages of the proposed algorithm is that high band and the low band coefficients can be exploited for several classes of signals resulting in very low computation
Facial Expression Recognition from Video Sequence Using Self Organizing Feature Map
Get PDFAutomatic analysis of facial expressions is rapidly becoming an area of intense interest in computer vision and artificial intelligence research communities. In this paper an approach is presented for facial expression recognition of the six basic prototype expressions (i.e., joy, surprise, anger, sadness, fear, and disgust) based on Facial Action Coding System (FACS). The approach utilizes the topological ordering patterns produced by Kohonen Self Organizing Map, in which implemented on expression image sequence for each prototype facial expression. The map will compute the topological relationship between the particular expression sequences, starting from the neutral expression to peak. This method tried to find a topological ordering pattern (shape) for each expression; it will not require any pre-processing tedious work such as normalization. The only requirement is that, image background must be kept constant, also with non-rigid head motion. The feature extraction phase had been performed by this method, while the classification phase done by especially designed procedures for shape and direction finding to recognize the pattern of the shape, thereafter the type of the expression also backpropagation neural network is implemented for the classification task. An average recognition rate of 88.7% was achieved for six basic expressions, where different databases had been used for the test of the method
