Inventor: LUCA HECTOR F DE
IPC: A61P43/00
Filed: 1983-09-20
Abstract: The process described in the present invention is characterised in that it consists in subjecting a 5,7-diene steroid having the formula: to the following stages: a. Irradiation with ultraviolet light to obtain the corresponding previtamin D; b. Isomerisation of previtamin D in an inert solvent at a temperature ranging from approximately ordinary temperature to approximately 100 DEG C to thus obtain a compound having the formula: c. Hydrolysis catalysed by an acid to remove the ketal protecting group, and d. Subjection of the ketone freed of the protecting group to alkylation with a reactant having the formula YMgHal or YLi, in which Y is an alkyl or aryl group and Hal represents chlorine, bromine or iodine, and optionally e. Acylation of one or both of the free hydroxyl groups, these stages being in any order provided that stage a precedes stage b and that stage c precedes stage d. Use of these derivatives of vitamin D2 for the treatment or prophylaxis of various pathological conditions, especially for calcium and phosphorus imbalances and as substitutes of vitamin D3 and of its metabolites in their various applications.

Filed: 1983-10-03
Abstract: 1. Process for the in vitro detection of a normally monocatenary nucleic acid, particularly of a determined RNA, in a biological medium containing it and containing cells, comprising the following steps : - treating the biological material by contacting said material with a non ionic detergent to solubilize the membranes of the cells contained in said biological material and release a part of the internal cellular constituents included in DNA, RNA and more particularly RNA messengers ; - dissociating, before hybridization, the monocatenary protein-RNA complexes, and unmasking the monocatenary RNA by means of a solution of an ionic salt, having a molarity from 5 M to 13 M, this mild treatment avoiding substantially the denaturation of bicatenary nucleic acids ; - contacting RNAs with a probe containing a complementary nucleotide sequence of the determined monocatenary nucleic acid, particularly of the determined RNA, under conditions enabling to allow hybridization of this probe with this determined nucleic acid ; - hybridization between the abovesaid probe and the determined monocatenary nucleic acid sequence, particularly the monocatenary RNA, in the presence of substantially bicatenary nucleic acids ; - detecting the hybrid possibly formed between the determined nucleic acid and the complementary sequence of the probe ; characterized in that RNA is deposited on an appropriate filter for the in situ hybridization and eliminate proteins.

Inventor: JAILLET ANDRE
IPC: F16F9/02
Filed: 1984-09-28
Abstract: A pneumatic spring is arranged with a view to putting a piece of electrical equipment into operation as soon as it reaches a given geometrical condition corresponding to a determined relative position of its piston rod, the device being equipped for this purpose with elastic strips which are arranged so as to be in contact at one time with the conducting wall of its tube, and to be separated from the latter at another time. The elastic contact strips are controlled by an insulating cam which is movable relative to them, and which is designed either to apply them against the wall of the tube if they are separated from it when at rest, or the reverse, that is to say to separate them from the wall of the tube if they are in contact with it when at rest. Such a spring can be used for automobiles.
