Modeling of Neuropathic Bladder Lesions Diagnosis Using Neural Network Algorithm.

The urinary bladder is probably the only visceral smooth-muscle organ that is under complete voluntary control from the cerebral cortex. Normal bladder function requires interaction of sensory and motor components of both the somatic and autonomic nervous system. Recent advances in the understanding of neural pathways and neurotransmitters have shown that most levels of the nervous system are involved in the regulation of voiding function. Therefore many neuralgic diseases causes changes in the bladder function [1]. In this paper, Number of patients selected from Ibn-Alkiff hospital (for treatment and rehabilitation of Spinal cord injuries), in Baghdad, who were referred to the urology department for complains of some urinary symptoms, and examined by cystometry in the urology out patient and/or inpatient department. These cases were selected randomly who already consult these departments and were followed up and managed by the expert urosurgeons. They were adults complaining of general neuropathic bladder disorder symptoms like frequency, urgency, dysuria, urinary incontinence and were diagnosed as having neuropathic bladder disease, whether: Upper motor neuropathic bladder lesions. Lower motor neuropathic bladder lesions. And finally they were examined by cystometry. The collections of data from patients were about: Accommodation (compliance). • Bladder capacity. • Contractility. • Sensation. • Voluntary control. These data with the final definition diagnosis about the neuropathic bladder lesion were processed to 3- layers Neural Network algorithm that was constructed in a matlab computer package. Consequently after all data processing, the neural network model was tested by its capability of processing an already diagnosed neuropathic bladder case and its accuracy in explaining the real neurological bladder behavior of that selected patien

EXPERIMENTAL STUDY OF FATIGUE CHARACTERISTICS OF LAMINATED COMPOSITE PLATES

The fatigue damage is a dangerous and could be considered as the most unwanted failure in the materials that are used to construct the engineering components. As composites take an advanced position in the industry of aircraft, marine and many other high performance components, because of their high ability and their light weight and for their strength, this forces us to find the deformation and data to give a good expectation for the composite behavior under fatigue and other types of damage. In this study the material used is the glass fiber with a polyester resin; the experiment used a device to force the composite to be under a bending fatigue through specified deflection and then the force is measured. The results for different values of imposed deflection and different thicknesses are presented, as S-N curves and in a logarithmic way.nFractography has been used to characterize the fatigue damage in the composite, it is shown that the fatigue damage in the composite is a complex, interactive damage process and combines between several damage mechanisms such as delamination, fiber breakage, matrix cracking and fiber matrix debounding

Prevalence of Staphylococcus aureus in Atopic Dermatitis (Eczema) cases in Al- Najaf City/Iraq

ABSTRACTObjectives: This study was planned to evaluate the prevalence of Staphylococcus aureus in cases of atopic dermatitis (AD) in Najaf city.A total of 100 skin swabs were obtained from the effected skin areas of patients who were attending to AL-Sader Teaching Hospital in AL-Najaf city during the period from May to October 2014.with (AD), along with 50 skin swabs that were obtained from a comparable skin area of 50 persons who were regarded as a control group and comparable in ages and genders with the patient group. All the skin swabs (patients and control) were then immediately streaked on the surface of selective media for isolation and identification of S. aureus preliminary. Then the suspected isolates were confirmed by specific biochemical and enzymatic confirmative tests. The incidence of Staphylococcal isolates was detected according to the age, gender, duration, severity and also according to the family history.Results: From the 100 swab samples of patients, there were 54/100 (54%) showed positive isolation of S. aureus, while only 10/50 (20%) swab samples of the control group showed positive S. aureus isolation. The difference between the two groups was statistically significant (P˂ 0.05). The prevalence of moderate AD cases was higher than that of mild and severe (55.56%> 20.37%˂ 24.07%) respectively. Thirty seven patients (68.52%) were categorized with family history inheritance of AD (Results were statistically significant (P˂ 0.05), with male to female ratio was 1.25:1. Seventeen patients (31.5%) were categorized as acute AD, while 37 patients (68.5%) were diagnosed as chronic.Conclusions: Staphylococcus aureus infection is positively correlated with AD cases, and genetic factors may play an important role in increasing the frequency of AD cases.Recommendations: We recommended to use genetic studies for the monitoring of Staphylococcus aureus virulence factors correlated with AD.Key words: Staphylococcus aureus, atopic dermatitis, SCORAD index

Ali Al-Wardi, his environment, his upbringing, and his educational efforts, a historical study

Iraq succumbed to its three states (Mosul, Baghdad, and Basra) under the brunt of the Ottoman occupation for nearly four centuries, most of which were characterized by backwardness, ignorance, and worsening health conditions due to endemic diseases and epidemics in the country, such as plague, tuberculosis, schistosomiasis, and others (1). The country witnessed a wide spread of nomadism in terms of population, appearances and values ​​in most of its regions in a way that Iraqi society had not seen before (2) with which the most prominent cities of Iraq, the "proverb of proverbs" in its golden ages during the Abbasid caliphate, turned into marginal cities - ruins, as they are

Free Vibration Characteristics of Elastically Supported Pipe Conveying Fluid

In this study, the effect of support values on the natural frequency and critical flow velocity of a straight pipe conveying laminar flowing fluid is studied. The aim of this work is deriving a new analytical model to perform a general study to investigate the dynamic behavior of a pipe under general boundary conditions by considering the supports as compliant material with linear and rotational springs. This model describes both the classical (simply support, free, built, guide) and the restrained boundary condition and it is not required to derive a new frequency equation if the boundary conditions is changed ,also the result will be near to reality by knowing the physical parameters for the compliant material and the pipe

Comparative study of lipoprotein lipase enzyme, ApoE and ApoC2, in pregnant women with and without preeclampsia

Background: Preeclampsia (PE) is a multisystemic syndrome specific to pregnancy. Although PE is the most common cause of death from pregnancy-related problems, its underlying cause is still unknown. In PE, lipid metabolism is altered. When lipids are damaged, both the mother and the foetus may be at risk. Methods: Blood samples were taken from 45 normotensive and 45 preeclamptic pregnant women. These samples were analyzed for LPL, Apo E and C2. Results: Concentrations of LPL, Apo C2 and Apo E differ significantly between preeclamptic women and pregnant controls which were higher in preeclamptic than in pregnant controls. Conclusions: In preeclamptic women, the increase in LPL, ApoC2 and Apo E concentration may serve as a marker for preeclampsia complication that which leads to worse consequences and could be a relevant factor in the pathogenesis of preeclampsia
