| 1 | Chronic permanent hypoxemia predisposes to mild elevation of liver stiffness显示文摘AIM:To evaluate the impact of long term permanent hypoxemia noticed in patients with non operated congenital cyanogenic cyanotic cardiopathy on liver stiffness.METHODS:We included ten adult patients with non operated inoperate cyanotic cardiopathy and ten matched patients for age and gender admitted to the gastroenterology department for proctologic diseases;Clinical and laboratory data were collected[age,gender,body mass index,oxygen saturation,glutamate oxaloacetate transaminase(GOT),glutamate pyruvate transaminase(GPT),glycemia and cholesterol].Measurement of hepatic stiffness by transient elastography was carried out in all patients using the Fibroscan device.All patients underwent an echocardiography to eliminate congestive heart failure.RESULTS:Among the patients with cyanotic cardiopathy,median liver stiffness 5.9±1.3 kPa was greater than control group(4.7±0.4 kPa)(P=0.008).Median levels of GOT,GPT,gamma-glutamyltransferase,glycemia and cholesterol were comparable in cardiopathy and control group.In regression analysis including age,gender,body mass index,oxygen saturation,GOT,GPT,glycemia,cholesterol showed that only oxygen saturation was related to liver stiffness(r=-0.63 P=0.002).CONCLUSION:Chronic permanent hypoxemia can induce mild increase of liver stiffness,but further studies are needed to explore the histological aspects of liver injury induced by chronic permanent hypoxemia. | Mohamed Tahiri Abdenasser Drighil Yasmine Jalal Dounia Ghellab Wafaa Hliwa Haddad Fouad Wafaa Badre Ahmad Bellabah Rachida Habbal Rhimou Alaoui | 2014 | World Journal of Gastroenterology2014，20，30： | 5 |

| 4 | Global threshold dynamics of an age structured alcoholism model显示文摘We consider in this research an age-structured alcoholism model.The global behavior of the model is investigated.It is proved that the system has a threshold dynamics in terms of the basic reproduction number(BRN),where we obtained that alcohol-free equilibrium(AFE)is globally asymptotically stable(GAS)in the case R_(0)≤1,but for R_(0)>1 we found that the system persists and the nontrivial equilibrium(EE)is GAS.Furthermore,the effects of the susceptible drinkers rate and the repulse rate of the recovers to alcoholics are investigated,which allow us to provide a proper strategy for reducing the spread of alcohol use in the studied populations.The obtained mathematical results are tested numerically next to its biological relevance. | Soufiane Bentout Salih Djilali Abdenasser Chekroun | 2021 | International Journal of Biomathematics2021，14，3： | 0 |
| 5 | Classification of Convective and Stratiform Cells in Meteorological Radar Images Using SVM Based on a Textural Analysis显示文摘This contribution deals with the discrimination between stratiform and convective cells in meteorological radar images. This study is based on a textural analysis of the latter and their classification using a support vector machine(SVM). First, we apply different textural parameters such as energy, entropy, inertia, and local homogeneity. Through this experience, we identify the different textural features of both the stratiform and convective cells. Then, we use an SVM to find the best discriminating parameter between the two types of clouds. The main goal of this work is to better apply the Palmer and Marshall Z-R relations specific to each type of precipitation. | Abdenasser Djafri Boualem Haddad | 2014 | Journal of Electronic Science and Technology2014，12，1： | 0 |
