AIM:to develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).MEtHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using ***:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination.

Background -Obesity is associated with heart failure, but an effect of weight , independent of comorbidities, on cardiac structure and function is not well es tablished. We sought whether body mass index(BMI) and insulin levels were associ ated with subclinical myocardial disturbances. Methods and Results-transthoraci c echocardiography, myocardial Doppler-derived systolic(sm) and early diastolic velocity(em), strain and strain rate imaging and tissue characterization with c yclic variation(CVIB), and calibrated integrated backscatter(cIB) were obtained in 109 overweight or obese subjects and 33 referents(BMIted with left ventricular(LV)-mass and wall thickness(Pts(BMI >35) had reduced LV systolic and diastolic function and increased myocardial reflectivity compared with referents, evidenced by lower average long -axis strain, sm, cIB, lower CVIB, and reduced em, whereas LV ejection fraction remained normal. Differences in regional or global strain, sm, and em were iden tified between the severely obese(BMI >35) and the referent patients(Nt lesser degrees of reduced function by sm, em, and basal septal str ain and increased reflectivity by cIB were present in overweight(BMI, 25 to 29.9 ) and mildly obese(BMI, 30 to 35) groups(Pthough tissue Doppler measu res were not associated with duration of obesity, they did correlate with fastin g insulin levels and reduced exercise capacity. BMI was independently related to average LV strain(β=0.40, P=0.02), sm (β=-0.36, P=0.002), and em(β=-0.41, Pt subjects without overt heart disease have su bclinical changes of LV structure and function even after adjustment for mean ar terial pressure, age, gender, and LV mass.

近年来,柴油机要求更高的性能和更长的寿命。由于气缸爆发压力高,活塞销衬套的工作负荷和温度变得更高。因此要求活塞销衬套具有高承载能力、耐磨性和耐腐蚀性。为了改善铜衬套材料的耐腐蚀性,研究了铜合金中添加元素的效果。研究发现,在铜中加入镍可降低铜合金的硫腐蚀。此外,还得知可以通过传统的烧结方法来生产铜镍合金。尝试在铜基体中加入硬颗粒来提高耐磨性。研究的首要目标是确定硬颗粒对耐磨性和切削加工工艺性的影响。研究发现,在铜基体中加入一种硬颗粒时耐磨性有所提高,但切削加工性却变差。为了解决这个问题,试验同时添加两种硬颗粒,细的ain和Fe3P颗粒。结果是成功地提高了耐磨性,又不使切削加工性变差。在本研究的基础上成功地开发了活塞销衬套新材料,有效地提高了高性能柴油机活塞销衬套的耐磨性和耐腐蚀性。

Study Objectives: Guillain-Barre syndrome (GBS) is an acute-onset, monophasic immune-mediated disorder of the peripheral nervous system that often follows an infection. the outcome and prognosis of GBS depend on many factors such as the etiology, clinical features, neurophysiology and immunological parameters. the aim of this study was to assess the factors (clinical, investigatory tools, and therapies) that may affect the outcome of patients with GBS. Patients and methods: this was an analytical observational study that was conducted at ain Shams university hospitals and Kobri Elkoba Military Hospital including twenty patients with the diagnosis of Guillain Barre Syndrome in the duration from 2016 to 2018. this study included twenty patients with the diagnosis of GBS within two weeks from onset of neurologic symptoms, whom their diagnosis based on the established clinical criteria and verified by investigations. Patients were selected from both genders and aged from 18 to 65 years old. Nerve conduction studies and electromyography were performed within two weeks from admission. Various lines of treatment such as plasma exchange (PE), intravenous immunoglobulins (IVIG) or both were used during the period of admission in hospital. Outcome was assessed by the Hughes functional score (F-score), that was applied to the patients on admission, at end of 4 weeks from onset of neuropathy and at the end of 8 weeks. the final outcome at the end of 8 weeks was classified as follow: Group I: good prognosis (0 - 2) on the Hughes functional score (15 patients) and Group II: poor prognosis (3 - 6) on the Hughes functional score (5 patients). Results: the age of the study population ranged from 18 to 65 years with mean of 36.10 ± 16.08 years. Fifteen (75%) patients were males and 5 (25%) patients were females. there was no statistically significant difference found between poor and good prognosis regarding gender. the most common electrophysiological subtype was demyelinating follo

the paper investigates the numerical solution of problem of magnetohydrodynamic (MHD) micropolar fluid flow with heat and mass transfer towards a stagnation point on a vertical plate. In this study, we consider both strong concentrations (n = 0) and weak concentrations (n = 1/2). the governing equations have been transformed into nonlinear ordinary differential equations by applying the similarity transformation and have been solved numerically by using the finite difference method (FDM) and analytically by using (DtM). the effects of various governing parameters, namely, material parameter, radiation parameter, magnetic parameter, Prandtl number, Schmidt number, chemical reaction parameter and Soret number on the velocity, microrotation, temperature and concentration have been computed and discussed in detail through some figures and tables. In order to verify the accuracy of the present results, we have compared these results with the analytical solutions by using the differential transform method (DtM) and the multi-step differential transform method (MDtM). It is observed that this approximate numerical solution is in good agreement with the analytical solution.

Colon cancer is the third leading cause of death in the US. Selected herbal teas and spices may reduce incidence of chronic diseases, including cancer. the objective of this study was to identify the effect of strawberry leaf, raspberry leaf, hibiscus teas and cinnamon on azoxymethane (AOM)-induced aberrant crypt foci (ACF) in Fisher 344 male rats. After acclimatization period (1 wk), 49 male weanling rats were divided into 16 groups. Control (CON) group fed ain-93G diet;15 treatment groups were administered control diet + strawberry leaf tea (StW), raspberry leaf tea (RAS), hibiscus tea (HIB), cinnamon (CIN), strawberry leaf tea + cinnamon (StW + CIN), raspberry leaf tea + cinnamon, (RAS + CIN), hibiscus tea + cinnamon (HIB + CIN), and strawberry leaf tea + raspberry leaf tea + hibiscus tea + cinnamon in combination (COM) at 2 levels each (teas added at 1% and 2%;CIN added at 2.5% and 5%). Rats received 24 mg/kg body weight AOM in saline s/c at 7 and 8 weeks of age. Animals received experimental diets until sacrificed by CO2 asphyxiation (17 weeks of age). ACF were enumerated in colons. Hepatic antioxidant enzymes were determined;superoxide dismutase (SOD), catalase (CAt), glutathione peroxidase (GPX), and glutathione (GH). treatment groups had reduction in ACF compared to CON (154). Lowest ACF observed in HIB 2% + CIN 5% (13.16) with 91.45% reduction compared to CON. ACF observed in treatment groups administered teas and cinnamon combinations were lower than those administered teas singly. SOD and CAt activities in rats administered treatment diets were higher than CON (13.63 U/mL, 0.95 umol·min-l·ml-1). Rats administered COM (20.65 U/mL) had highest SOD activity. CAt activity was 51.27% higher in rats administered HIB 2% (1.96 umol·min-l·ml-1). GPX activity ranged from 7.26 (StW 1% + CIN 2.5%) to 9.59 (StW 2%) umol·min-l·ml-1. Results suggest that herbal teas and spices may reduce the risk of colon cancer and improve antioxidant status;regular consumption may pro
