BACKGROUND: Cerebrovascular accident(CVA) is the third leading cause of death and disability in developed countries. Anyone suspected of having a stroke should be taken immediately to a medical facility for diagnosis and treatment. The symptoms that follow a stroke aren't signi? cant and depend on the area of the brain that has been affected and the amount of tissue damaged. Parameters for predicting long-term outcome in such patients have not been clearly delineated, therefore the aim of this study was to investigate this possibility and to test a system that might practicably be used routinely to aid management and predict outcomes of individual stroke ***: A descriptive hospital-based study of the neurological symptoms and signs of 503 patients with ischemic stroke, including severe headache, seizure, eye movement disorder, pupil size, Glasgow Coma Scale(GCS), agitation were analyzed in this ***: In the current study, dilated pupils, agitation, acute onset headache, lower GCS score, seizure, and eye gaze impairment had signi? cantly higher prevalence in hemorrhagic stroke patients(P<0.001). However, the rate of gradual progressive headache is significantly higher in ischemic stroke patients(P<0.001).CONCLUSION: Although this result provides reliable indicators for discrimination of stroke types, imaging studies are still the gold standard modality for diagnosis.

BACKGROUND: Trauma is considered as a worldwide problem despite socio-economic development. Motor vehicle accidents(MVAs) are the most important cause of trauma. Trauma related deaths are mostly preventable. This study aimed to investigate the causes and prevention of death in trauma ***: This retrospective, descriptive-analytic study assessed 100 trauma patients referred to our emergency department(ED) from January 2013 to Januanry 2015. The included patients were those with trauma died after arrival at our ED. Age, sex, cause of trauma, clinical causes of death, causes of death def ined by autopsy, way of transfer to the ED, time of ambulance arrival at the scene of trauma, and time elapsed to enter the ED from the scene of trauma were ***: In the 100 patients, 21(21%) patients were female and 79(79%) male. Fortythree patients were older than 60 years. Trauma was largely due to pedestrian accidents in 31% of the patients, and 33% had a hypo-volemic shock. About 80% of deaths were due to intra-cranial hemorrhage(ICH) or intra-ventricular hemorrhage(IVH), and spinal injuries were not preventable. Autopsy revealed that 28% of the patients suffered from internal injuries. Autopsy revealed that 19% of the deaths were not preventable and 81% were considered preventable. In our patients, 76 were transferred to the hospital by emergency medicine services(EMS). Analysis of time for ambulance arrival to the scene and frequency of death revealed that 52.2% of the deaths occurred between 11 and 15 minutes. Analysis of time for admission to the ED from the scene of trauma showed that 74.6% deaths occurred between 6 and 10 ***: The rate of hospital preventable deaths is about 80%, a high mortality rate, which denotes a lack of proper diagnosis and treatment. The time for arrival of EMS at the scene of trauma is longer than that in other countries.

Physio-biochemical and nutrient constituents of peanut plants under bentazone herbicide for broad-leaved weed control and water regimes in dry land areas

引用

Journal of Arid Land 2020年第4期12卷 630-639页

作者： Hani S SAUDY Ibrahim M EL–METWALLY Goma A ABD EL–samad Agronomy Department Faculty of AgricultureAin Shams University68–Hadayek Shoubra 11241CairoEgypt Botany Departments National Research CentreEl–Behos St.Dokki 12622CairoEgypt

The abundance of broad-leaved weeds in peanut fields represents the handicap in weed management programs, since limited specific herbicides can be recommended to control them. Moreover, the physio-biochemical constituents and nutritional status in peanut plants as affected by available herbicides, i.e., bentazone under water stress conditions are not well known. Therefore, field trials were conducted during the growing seasons in 2016 and 2017 to investigate the interactional impact of irrigation levels(I_(50), I_(75) and I_(100), representing irrigation by 50%, 75% and 100% of crop evapotranspiration, respectively) and weed control practices(bentazone, bentazone+hoeing once, hoeing twice and weedy check as control) on dominant broad-leaved weeds as well as peanut physiological and agronomic traits. Result indicated that the efficiency of weed control for each weeded treatment under I_(50) significantly equaled with its counterpart under I_(75) or I_(100). Bentazone+hoeing once diminished weed biomass by 89.3% and enhanced chlorophyll content of peanut plants by 51.2%. Bentazone relatively caused a reduction in carotenoides. Hoeing twice and bentazone+hoeing once under I_(100) in both growing seasons as well as hoeing twice under I_(75) in 2017 were the superior combinations for boosting pod yield of peanut plants. Treatment of bentazone+hoeing once and I_(75) recorded the lowest reduction in N utilization percentage and the highest increase in potassium utilization percentage of peanut plants. Eliminating weeds enhanced water use efficiency by 37.8%, 49.6% and 34.7% under I_(50), I_(75) and I_(100), respectively. In conclusion, peanut seems to be tolerant to bentazone at moderate water supply, thus it can be safely used in controlling the associated broad-leaved weeds.

Rare earth oxides doped NiO/γ-Al_2O_3 catalyst for oxidative dehydrogenation of cyclohexane

引用

Journal of Rare Earths 2015年第6期33卷 611-618页

The effect of rare earth oxides （RE=Ce, La, Gd, and Dy） doping of alumina support in NiO/7-A1203 system was investi- gated on its catalytic performance in oxidative dehydrogenation （ODH） of cyclohexane. The physicochemical properties of various samples were followed up through N2 physisorption, temperature programmed reduction （H2-TPR）, X-ray diffraction （XRD）, X-ray photoelectron spectroscopy （XPS） and potentiometric acid-base titration techniques. In the parent NiO/y-A1203 catalyst, Ni species were found to be strongly interacted with alumina surface. Addition of rare earth dopants to ）＇-A1203 in the catalyst system affected the nickel-alumina interaction and resulted in significant modifications in the catalytic performances in the ODH reaction. The results re- vealed the beneficial role of both La203 and Gd2Os doping in enhancing the ODH catalytic activity and selectivity to cyclohexene. H2-TPR and XPS results indicated that majority of Ni species in NiO/La203 modified T-A1203 were more weakly interacted with La203 and alumina whereas both NiO like species and nickel aluminate were present on the surface. Doping with cerium or dyspro- sium increased the nickel-support interaction and led to a decrease in surface nickel concentration. In case of doping with Ce, surface concentration of cerium oxide was higher than those of the other RE oxides; the doped catalyst reached its steady state activity faster than the other catalysts. The acid-base results suggested that RE metals were interacted most likely with acidic surface hydroxyl groups. The degree of nickel-alumina interaction decreased in the following order： LaAI〉GdAI〉CeAI〉DyA1.
