La composition en acides gras et phospholipides mitochondriaux hépatiques a été étudiée chez le charnelon, sous différentes conditions physiologiques et nutritionnelles. Les résultats obtenus ont montré que les phosphatidylcholines et les phosphatidyléthanolamines sont les phospholipides majoritaires avec plus de 63 p. 100 des phospholipides totaux ; elles ont un taux plus élevé que chez d'autres espèces. Les phosphatidylinositols représentent le plus faible taux avec 5 p. 100 environ, alors que les sphingmyélines, qui semblent être à l'état de trace chez le rat, représentent plus 14 p. 100 ch...

The cyclization of 2-benzyl-4-pentenoic acids, catalyzed by protonic and Lewis acids, resulted in the formation of variable quantities of α-benzyl-γ-valerolactones and tetrahydronaphthalenecarboxylic acids (65 – 85%) which, after reduction and dehydrogenation, yielded tetramethylnaphthalenes substituted in the 1,3-positions. 1,3,5,7-Tetramethylnaphthalene, in particular, had not as yet been described. Aluminium chloride favors cyclization and does not give rise to lactonization, but it induces secondary reactions such as the migration of methyl groups.

Résumés Français Anglais DHEA, SDHEA et androstènedione sont des stéroïdes en C19 sécrétés par la glande surrénale. Chez l’homme, ces hormones sont produites en quantités importantes, notamment pendant la période prépubertaire. Chez les animaux domestiques et de laboratoire, la sécrétion de ces hormones demeure relativement faible. Au cours de ce travail, l’androstènedione est évaluée par radio immunoassay (RIA) dans le plasma et dans la glande surrénale du lapin à différents âges. Les effets de la castration de 28 jours chez l’adulte sont constatés sur des coupes histologiques colorées au tri...

Abstract En ajoutant à un acide aminé ou peptide N‐acylé dans un solvant organique une amine tertiaire (tri‐n‐butylamine), puis du chloroformiate ( = chlorocarbonate = chlorométhanoate) d'éthyle (ou de méthyle) en quantités équimoléculaires, on obtient immédiatement une solution contenant des anhydrides mixtes de la forme: magnified image Si, à une telle solution, on ajoute une solution aqueuse ou organique d'un acide aminé, d'un peptide, d'un ester de ceux‐ci, ou d'une amine, on obtient sur le champ la formation d'une liaison peptidique, avec dégagement de CO 2 . Grâce à cette méthode simple...

Whereas the pseudo-axial 3-hydroxyl group of allal derivatives is known to be inert to manganese dioxide oxidation, the equatorial counterpart in glucal derivatives is shown to be readily oxidized. Thus glucal is converted to the 6-O-triphenylmethyl ether or 6-O-benzoyl ester to promote solubility in chloroform, and the derivatives are oxidized in that solvent in 12 h or less.Acetonation of glucal is readily accomplished in 45 min using 2,2-dimethoxypropane and p-toluenesulfonic acid in dimethylformamide; the product may be oxidized directly either with manganese dioxide or dipyridine chromium...

Bridelia ferruginea is a traditional African medicine plant involved in treatment of several diseases. It is used as a purgative and has diuretic properties. The aim of this study is to evaluate the effect of an aqueous extract of the stem bark of this plant on renal function in the male Wistar rats. Twenty-four hours after the administration in rat, the aqueous extract of Bridelia ferruginea (SEA) causes an increase in creatinine excretion in the urine of 88.10% (P < 0.01). SEA provokes a significant increase (P < 0.05) in creatinine clearance. It does not significantly modify the content and...

This study describes the first ever reported direct observation of a pair spawning event and the reproductive liveries of the white grouper, Epinephelus aeneus. Spawning took place on a rocky bank located in the Marine Protected Area (MPA) of Tavolara-Punta Coda Cavallo (NE Sardinia, Italy), in the Western Mediterranean Sea. In the evening of August 4th, 2018, the spawning of two large-sized individuals (~90 cm total length), displaying distinct colour patterns, was observed using SCUBA diving. This direct observation is the first record of E. aeneus male reproductive livery, characterized by...

Pollution of metal origin constitutes one of the major risks in the world today. The metal elements can be very dangerous to human health when they are present in the environment at high concentrations. Thus, the evaluation of the metal contamination in marine organisms, especially fish, makes it possible to predict a possible contamination of humans. This paper focuses on studying the metal contamination of the beach of Soumbédioune, located at the western frontage of the area of Dakar. This site, where fish products are offloaded, is the home to Canal IV (West Canal), which drains urban wast...

La visée d’une société pour tous est souvent remise en question dès qu’il s’agit des personnes présentant un handicap mental. De nombreux constats envisagent la nécessité à ce que les professionnels agissant avec ces personnes travaillent ensemble . Mais travailler ensemble n’est pas un allant-de-soi. Ce faisant, que se passe-t-il quand des acteurs deviennent capable de travailler ensemble ? Dans cet article, nous allons décrire et analyser l’activité d’un collectif, prenant la forme d’une ingénierie coopérative (Sensevy, 2011), composée de professionnels d’un Esat (Établissement service d’aid...

A semi-analytical approach for the pulsating solutions of the 3D complex Cubic-quintic Ginzburg-Landau Equation (CGLE) is presented in this article. A collective variable approach is used to obtain a system of variational equations which give the evolution of the light pulses parameters as a function of the propagation distance. The collective coordinate approach is incomparably faster than the direct numerical simulation of the propagation equation. This allows us to obtain, efficiently, a global mapping of the 3D pulsating soliton. In addition it allows describing the influence of the parame...

A semi-analytical approach for the pulsating solutions of the 3D complex Cubic-quintic Ginzburg-Landau Equation (CGLE) is presented in this article. A collective variable approach is used to obtain a system of variational equations which give the evolution of the light pulses parameters as a function of the propagation distance. The collective coordinate approach is incomparably faster than the direct numerical simulation of the propagation equation. This allows us to obtain, efficiently, a global mapping of the 3D pulsating soliton. In addition it allows describing the influence of the parame...

Abstract: Modernization of agriculture is associated with increased use of energy and inputs (fertilizers, plant protection products, water), which today need to be better managed for optimization purpose and to limit risks for people and the environment. This issue has given rise to smart agriculture, a relative new approach to farming based on the integration of information and communication technologies, particularly Artificial Intelligent (AI) and Internet of Things, in which the environment (soil, relief, air, etc.) represents potential data source that should be exploited. In this work,...

Power control is a major issue in the deployment of 4G mobile networks. Indeed, environmental constraints (relief, Air, noise,...) affect the propagation channels of mobile network systems. The new multimedia services, which consume large amounts of radio resources (frequencies), then lead to an optimization of power control in the cellular coverage in the uplink direction. The aim is to optimize the capacity of radio resources in the cellular coverage based on a COST-231 Walfisch-Ikegami semi-empirical propagation model for power control in the upward direction. It is a question of studying t...
