We propose a generalization of non-commutative geometry and gauge theories based on ternary Z 3-graded structures. In the new algebraic structures we define, we leave all products of two entities free, imposing relations on ternary products only. These relations reflect the action of the Z 3-group, which may be either trivial, i.e. abc = bca = cab,… (More)

We introduce Z 3-graded objects which are the generalization of the more familiar Z 2-graded objects that are used in supersymmetric theories and in many models of non-commutative geometry. First, we introduce the Z 3-graded Grassmann algebra, and we use this object to construct the Z 3-matrices, which are the generalizations of the supermatrices. Then, we… (More)

INTRODUCTION
Perioperative chemotherapy is the gold standard treatment of the resectable gastro-oesophageal adenocarcinoma. However, 70% of patients cannot receive the complete sequence because of a postoperative complication or a decrease in functional and nutritional reserves. Recently, a new concept appeared in digestive surgery: prehabilitation. This… (More)

BACKGROUND
Adjuvant chemotherapy for colorectal cancer is mainly based on the combination of 5-fluorouracil, folinic acid and oxaliplatin (FOLFOX-4). The pharmacological target of oxaliplatin remains intracellular and therefore dependent on its entry into cells. The intracellular distribution of oxaliplatin is mediated by organic cation transporters 1, 2… (More)

Microscopical and molecular analyses were used to investigate the diversity and spatial community structure of spring phytoplankton all along the estuarine gradient in a macrotidal ecosystem, the Baie des Veys (eastern English Channel). Taxa distribution at high tide in the water column appeared to be mainly driven by the tidal force which superimposed on… (More)
