Treatment of a juxtarenal aneurysm with a parallel graft in the left renal artery and polymer-based technology to seal the entire aneurysmal sac
No full textBackground Presenting the treatment of a juxtarenal aneurysm using a Nellix device combined with a chimney stent in a renal artery. Case Report A 72-year-old woman was diagnosed with a 5.5-cm bilobed juxtarenal aneurysm. She underwent successful aneurysm repair with the Nellix system combined with a chimney stent in the left renal artery. Angio computed tomography control showed complete sealing of the aneurysm sac and patent chimney stent. Conclusions Endovascular aneurysm sealing combined with chimney may be a valid way to treat juxtarenal aneurysms, and the conformable polymer-filled endobags may provide a durable seal around the chimney-graft preventing gutter formation
Grotte des Rhinocéros at Oulad Hamida Quarry 1, Morocco
No full textInternational audienceGrotte des Rhinocéros (GDR; 33.567°N, −7.701°W) is a hominin-bearing Middle Pleistocene site located on the western outskirts of Casablanca, Morocco’s economic capital. It was documented in 1991 during quarry work in the Oulad Hamida Quarry 1 (OH1), formerly known as Ben Sina 1. Together with the neighboring Thomas Quarry I sites, GDR belongs to the oldest hominin-bearing cluster of sites around Casablanca. The initial hominin occupation episode at the site is estimated to have occurred c. 0.7 Ma based on recent radiometric dating. It is one of the few early Middle Pleistocene sites in Africa in which animal consumption is directly associated with Acheulean stone tool manufacture in a cave context. The record seems to suggest repeated hominin occupation of specific locales in the landscape that afforded them survival benefits, such as protection against environmental events, as well as the development of a structured space for prolonged social and economic activities, including butchery, feeding, socialization, mating, and giving birth. Due to its richness of lithics in a securely dated stratigraphic context and in close association with a very rich faunal assemblage, OHQ1-GDR was selected to be the type-locality for the Second Regional Acheulean. Lastly, GDR holds a great potential for revealing behavioral innovations by hominin groups that occupied the Mediterranean littoral of North Africa during the early Middle Pleistocene
Early Homo on the Atlantic Shore: The Thomas I and Oulad Hamida 1 Quarries, Morocco
No full textInternational audienceThe sites discussed here were first reported by Biberson (1961a) under the name of “carrières Thomas” derived from the name of the worker of these quarries. There were three of them, called Thomas I, II, and III from the NE to the SW, at 33.568° N, 7.698° W, in what are now the suburbs of Casablanca. Biberson did not use them much in his major synthesis (1961a) and proposed simplistic correlations based on mollusk faunas between Sidi Abderrahmane and Thomas Quarries successions, but this did not help to clarify the complex stratigraphy of the beginning of the Moroccan coastal Middle Pleistocene, where continental and marine deposits interdigitate; finally, Biberson reported some fossils of unknown whereabouts. In 1969, while the quarries were being worked for their calcarenite, a young student, Philippe Beriro, found a human mandible in a cave opened by quarry works at Thomas I. The mandible was first reported by Ennouchi (1969, 1970) and studied in more detail by Sausse (1975). Soon after, hominin remains were discovered in a cave in Thomas Quarry III (Ennouchi, 1972, 1975, 1976), but the site was rapidly destroyed by quarry works. All hominin fossils from Thomas quarries were at the time referred by Ennouchi (1970) to Atlanthropus mauritanicus. Later, Thomas Quarries I and II were merged into Thomas I, and the name of Thomas Quarry III changed first to “Ben Sina” and later to “Oulad Hamida 1,” which is the local toponym. Fossils associated with the human remains, as well as other fossils and Acheulean artifacts, were briefly studied by Geraads (1980a) and Geraads et al. (1980). At that time, one of us (J.-P.R.), together with Jean-Pierre Texier, was starting a revision of the Moroccan coastal Quaternary, for which the Thomas Quarries were key localities; he was joined by D.L. in 1989. Archeological excavations in several levels of Thomas Quarry I have been undertaken from 1988 onwards by J.-P.R. and colleagues, to be complemented in 1991 by the excavation in Oulad Hamida 1 Quarry of a large cave called “Grotte des Rhinocéros (GDR),” which is in geometric continuity with what Geraads (1980a) had called “fissures dans le Tensiftien de Thomas III.
Amplification of the active site of BnLIP3 gene of Brassica napus L. during germination
No full textLipases are useful enzymes that are responsible for the hydrolysis of triacylglycerides and play an
important role in plant growth. In this study, we report a rapid molecular method to amplify a partial
sequence of the lipase class 3 family designated BnLIP3 gene of Brassica napus L. in order to follow its
expression and analyze its role during seed germination. Therefore, we conceived PCR homologous
primers to amplify the active site encoding region of the BnLIP3 family genes. Subsequently, to
sequence determination of the 582 bp fragment, we deduced BnLIP3 specific primers for a nested RTPCR
application. The deduced 194 amino acid sequence (Genbank 1160264) was found to share 85% of
identity with lipase from Arabidopsis thaliana class 3 family. The GxSxG consensus motif near the
catalytic triad at the active serine site was also identified. The peptidic sequence showed little
homology with mammalian and microbial lipases. RT-PCR analysis indicated that BnLIP3 gene was
expressed during B. napus seed germination.Glaied Ghram, I.; Belguith, H.; Messaoudi, A.; Fattouch, S.; Vicente Meana, Ó.; Ben Hamida, J. (2013).
