Biologie Résumé : Research on cereals in recent years, Indicate the risk of epidemic development of certain fungal diseases (rust yellow blotch, Septoria, etc.), and viral adequate measures of prevention and intervention are not taken in time (A.Ouffroukh. 2008; A.Ouffroukh, 2006). Crop losses arising are important. In favorable years the Yellow rust, for example, can take extents epidemic and destroy entire harvests. (A.Ouffroukh., 2008; A.Ouffroukh., 2006; B. Bahri, M. Leconte, A. Ouffroukh, C. Vallavieille-Pope, J. Enjalbert, 2009). Viral diseases in turn, are taking extension. Thus, the Barley Yellow Dwarf Virus (BYDV.) or (BYDV) was reported in several areas prospected and several cereal species (wheat and barley hard and soft).
In general very little information is available on their epidemiology and economic impact, when the means of struggle, they have little or almost nonexistent (H. Stone and JP Signoret, 1978). BYDV (BYDV) little known in Algeria compared to other diseases, can be very important for our cereal and threatening, particularly since this disease is transmitted by insect vectors belonging to the genus including Aphidideae, including a dozen some species have been identified (A.Ouffroukh., 2006; L. Ayadi K. and Ayoub, 1994; Ouffroukh. A Khelifi. D, Dehimet. L, 2009). Also after his observation and detection, identity veered ¬ was confirmed by serological investigations have shown that the existence of two viral strains or Pathotypes (PAV and MAV), confirming the results obtained by H. Belkahla.et Lapierre (1999).
The frequency of the disease varies annually from 8% to 18% depending on the region but is also encountered and generally on the different species at rates ranging from 8% to 28%. (L. Ayadi K. and Ayoub, 1994; A. Ouffroukh., 2008; Ouffroukh. A Khelifi. D, Dehimet. L, 2009).
In terms of capacity vector, PR appears to be best vector and infected plants by this species appear most affected clinically, about the impact of contamination on cereal species studied, it appears that the barley species are most affected, while soft wheats are more susceptible to BYDV (BYDV) and durum wheats.
Moreover, the influence of virus Barley yellow dwarf (BYDV) on cereal development is certain and it is especially important that the plant is subjected to water stress, it's more 'is that cultivars and genotypes most tolerant in general show a certain level of tolerance to drought.
In epidemiological terms, and although the results we have achieved can not definitively conclude on the precise conditions of the regions studied, the fact remains that valuable information was obtained. It appears here the whole point estimates of aphid that are a fundamental element .indication of risk to crops and therefore the periods in which the actions of prevention and protection should be carried out.Diplôme : Doctorat en sciences En ligne : ../theses/biologie/OUF6463.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9503 Contribution à la connaissance des stress biotiques affectant les céréales d'hiver : « Identification et approche à l'étude épidémiologique du virus de la jaunisse nanisante de L’Orge (VJNO) ou (BYDV) sévissant dans les cultures des céréales dans les zones Est de l’Algérie ».

BiologieTags : Biologie Animale: Génétique Moléculaire Gliomes épidémiologie susceptibilité génétique GWAS SNP survie epidemiology glioma risk survival الأورام الدبقية الدراسة الوبائية مظهر وراثي معدل النجاة Index. décimale : 570 Sciences de la vie. Biologie Résumé :
Gliomas are the largest group of malignant brain tumors in adults. Epidemiological, clinical, translational, and fundamental research have made significant progress in our understanding of these tumors. Nevertheless, the data on the populations of the developing countries remain very scarce, especially because of the rarity of these tumors. The purpose of our study was to develop an epidemiological and genetic profile of patients with glioma in the East-Algerian population. The epidemiological part was based on the records of patients admitted to the radiotherapy-oncology department of the University Hospital Center of Constantine between January 2008 and October 2016, in total 366 records were examined. The genetic part concerned 66/77 patients enrolled at the same hospital between March 2014 and October 2016 as well as 72/82 controls. We analyzed a series of 26/29 polymorphisms identified by GWAS as associated with the risk of gliomas. Our population was young (average age 44.6 years) with a relatively good overall survival (5-year rate of 38.1%). Genetic analysis showed a single polymorphism strongly associated with glioma risk; rs2736100 (5p15.33, TERT). Two other germinal variants gave
significant p-values in their heterozygous form; rs6010620 (20q13.33, RTEL1) for association and rs4977756 (9p21.3, CDKN2B-AS1) for protection. The total number of alleles at risk was associated with susceptibility but not with patient survival. Survival was associated with rs3851634 (12q23.33, POLR3B), rs3751667 (16p13.3, LMF1) and rs12076373 (1q44, AKT3). The profile of genetic susceptibility to gliomas in our population may therefore be different from other global populations already described
