摘要:
Composition for application, in particular to leaves, comprising an excipient, the conventional constituents of compositions for application, in particular to leaves, and an active ingredient, characterized by the fact that the active ingredient is constituted by at least one phytosanitary product capable of stimulating the germination of pollen grains, selected from the group comprising: oligosaccharides having a degree of polymerization up to 10 and comprising up to 10, preferably up to 5 and, even more preferably, two glucidic units linked by &bgr;1-3, &bgr;1-4 et &agr;1-3, particularly those of the group comprising laminaribiose, cellobiose, nigerose, laminaritriose, laminaritetraose and laminaripentaose, derivatives of the above oligosaccharides substituted on the free anomeric carbon atom or on all the carbon atoms having a free hydroxide by a radical selected from the group comprising: C1 to C5 alkyl radicals, preferably the methyl radical, C1 to C5 acyl radicals, preferably the acetyl radical, aryl radicals, preferably pyridylamino radicals, cycloalkyl radicals from Cx to Cy, amines, the N-acetyl radical and sulfate and phosphate radicals.
摘要:
A cosmetic or pharmaceutical, particularly dermatological, composition including an effective amount of laminarin or laminarin-derived oligosaccharides as the active ingredient. It has been discovered that laminarin, oligosaccharides derived therefrom and compositions containing same have stimulating, regenerating, conditioning and energising effects on human dermis fibroblasts and human epidermis keratinocytes. Said composition is useful in cosmetics and pharmacology.
摘要:
The invention concerns a medicine comprising, as active principle, an efficient quantity of at least an oligosaccharide substance capable of modulating apoptosis dysfunction which is capable of modifying apoptosis dysfunctions said substance being selected from the group consisting of oligosaccharides which are derived, by enzymatic or chemical process, from the polymers of the group comprising (1→3)-&bgr;-glucans which optionally comprise (1→6)-&bgr;-branching, and oligosaccharides which are derived, by enzymatic or chemical process, from sulfated galactans, it also concerns a method for treating apoptosis dysfunction.
摘要:
The invention concerns endofucanases suitable for preparing fuco-oligosaccharides by enzymatic hydrolysis of fucanes. It also concerns a bacterium producing endofucanases and the preparation of said enzyme from the bacterium. It further concerns endofucanase genes and it finally concerns the use said fuco-oligosaccharides for plant protection.
摘要:
The present invention provides a method to potentiate and stimulate natural defensive reactions of plants to a pathogenic agent. The method comprises application to plants of a composition comprising an effective amount of one or more oligo &bgr; 1-3 glucans composed of 3 to 250 monosaccharide units and a vehicle, wherein the effective amount of oligo &bgr; 1-3 glucans in the composition does not directly stimulate natural defensive reactions of plants when the pathogenic agent is absent.
摘要:
The invention relates to an automated method for positioning eggs on a tray that comprises the automated detection of the presence/absence of eggs in the cells of a tray, and the picking-up of eggs from a supply and the placement thereof in the empty cells of a tray. The invention also relates to a system or positioning eggs on a stabilizing tray, the tray including evenly distributed cells in which the eggs are placed, one or more cells being likely not to contain eggs, this information being stored in an information processing unit, wherein said system includes a means in the form of a robot having an egg pick-up head that are driven by the information processing unit in order to pick up eggs from a supply tray and to place them in the empty cells of the stabilizing tray.
摘要:
The subject matter of the present invention is a composition for inhibiting urease and nitrification, which may be in liquid or solid form and which comprises at least one compound for inhibiting urease, of phosphoramide type, combined with an essential oil of Allium preferably originating from Allium sativum. This composition may be used in combination with a urea-based fertilizer for the manufacture of fertilizing compositions.
摘要:
The present invention concerns an injection method for injecting a substance into eggs, and an injection head for implementing said method. The method generally includes piercing the shell and at least the shell membrane of an egg by moving a needle, and then injecting the treatment substance via said needle, said piercing step comprising a first movement of the needle to pierce the shell with a first penetration force and then a second movement of the needle to pierce at least the shell membrane with a second penetration force lower than the first penetration force.
摘要:
This invention relates to the use of a sulphated or phosphated polysaccharide for the preparation of a medicine for treatments against retroviruses, more particularly against lentiviruses and oncoviruses, and particularly against HIV, including strains of these retroviruses that are resistant to known anti-retroviral agents; this medicine acts on the replication cycle of said retroviruses by inhibition of their RT.
