Hereditary combined deficiency of the vitamin K-dependent clotting factors
2010
Abstract Hereditary combined vitamin K-dependent clotting factors deficiency (VKCFD) is a rare congenital bleeding disorder resulting from variably decreased levels of coagulation factors II, VII, IX and X as well as natural anticoagulants protein C, protein S and protein Z. The spectrum of bleeding symptoms ranges from mild to severe with onset in the neonatal period in severe cases. The bleeding symptoms are often life-threatening, occur both spontaneously and in a surgical setting, and usually involve the skin and mucosae. A range of non-haemostatic symptoms are often present, including developmental and skeletal anomalies. VKCFD is an autosomal recessive disorder caused by mutations in …
Carence en fer : comment y remédier par son alimentation
2022
Le fer est indispensable à notre bonne santé, c’est un fait. Mais comment nous assurer que notre alimentation nous apporte ce dont nous avons besoin ? Commençons par détruire un mythe… Les épinards de Popeye ne sont pas riches en fer. La teneur n’y est que 2,1 mg par 100 g d’épinards frais...
Effect of leaf removal and ripening stage on the content of quercetin glycosides in Sangiovese grapes
2021
Quercetin haze has been observed over the last few years in some aged Sangiovese wines. This problem could be due to an excess of the quercetin in the wine. Leaf removal increases the exposition of clusters to sunlight, which may enhance flavonol synthesis in the grapes. In this study, we evaluated the dynamics related to extractable flavonols in grapes grown in three usually defoliated Vitis vinifera (L.) cv. Sangiovese vineyards, whose wines showed quercetin precipitates. The particular structure of the vineyards in which the leaf removal experiments were carried out allowed the influence of vineyard, biotype and rootstock on grape flavonol contents at mid-maturation and technological mat…

Pourquoi le fer est indispensable à notre santé
2022
On ne s’en rend généralement pas compte, mais le fer est un atome essentiel à la vie. Chimiquement parlant, il appartient à la famille des métaux dits « de transition », capables d’échanger facilement des électrons : pour traduire cela en termes simples, cela signifie que cet atome donne aux molécules biologiques auxquelles il est attaché une grande réactivité et leur confère des propriétés chimiques importantes (d’oxydo-réduction par exemple) et, par voie de conséquence, des activités biologiques essentielles...
Étude de la biologie d'une messicole en régression: le bleuet (Centaurea cyanus L.)
2011
Agroecosystems are currently experiencing high biodiversity loss, in particular among the plant species specifically adapted to this habitat. This decline results from cropping systems that have been intensified in Western Europe since the 1950s. The cornflower (Centaurea cyanus L.), considered as emblem of the flora associated with traditional cereals, appears as a species that may be at risk and should be monitored. Indeed, cornflower can serve as a host to predators of crop pests and is strongly attractive for the pollinators. This study examines the biological factors that could potentially cause the decline of this species: spatial distribution, potential for growth, population's genet…
