Process for depositing by electrografting a strong adherent polymer coating onto an electrically conductive surface comprising an electrochemical grafting at the surface of an active monomer for forming a primer coating P onto said surface and having as general formula: X0 (meth)acrylate wherein X is either part of a preformed polymer or is an intermediate agent for polyaddition reaction or is an anchoring group for attachment of a molecule having at least one complementary reactive group. Such process allows formation of new primer by one-step electro-grafting of a reactive polymer called macromonomer.; Such process also allows further modification of an initial electrografted polymer (called primer coating) to increase the coating thickness by the so-called grafting-from technique i.e. polymerization of a second monomer or to introduce other types of polymers(also called top coating) via covalent attachment between the primer and the top coating through the X ester group by the so called grafting onto technique. Such process also allows to graft onto the primer coating compounds like functional polymer, peptide, protein, oligonucleotide, dyes, drugs, anti-bacterian compounds. [less ▲]

PROBLEM TO BE SOLVED: To provide a novel process for producing a homopolymer, a random copolymer, or a block copolymer having a controlled molecular weight, a narrow molecular weight distribution, a high monomer conversion ratio, and a controlled structure. ; SOLUTION: The polymer having a controlled molecular weight, a narrow polydispersibility, a high monomer conversion ratio, and a controlled structure is produced by polymerizing a vinyl monomer during the formation of a mixture of a hindered secondary amine and an oxidizing agent at a relatively low temperature in a short reaction time. It is unnecessary to add a free radical initiator before polymerization. Further, it is unnecessary to preliminarily react the secondary amine with the oxidizing agent before adding the monomer.

Process for depositing by electrografting a strong adherent polymer coating onto an electrically conductive surface comprising an electrochemical grafting at the surface of an active monomer for forming a primer coating P onto said surface and having as general formula: X0 (meth)acrylate wherein X is either part of a preformed polymer or is an intermediate agent for polyaddition reaction or is an anchoring group for attachment of a molecule having at least one complementary reactive group. Such process allows formation of new primer by one-step electro-grafting of a reactive polymer called macromonomer.; Such process also allows further modification of an initial electrografted polymer (called primer coating) to increase the coating thickness by the so-called grafting-from technique i.e. polymerization of a second monomer or to introduce other types of polymers(also called top coating) via covalent attachment between the primer and the top coating through the X ester group by the so called grafting onto technique. Such process also allows to graft onto the primer coating compounds like functional polymer, peptide, protein, oligonucleotide, dyes, drugs, anti-bacterian compounds. [less ▲]

A gene (cDNA) encoding a bovine myostatin protein. The nucleic acid coding sequence is identified as SEQ ID NO:1 and the protein sequence is identified as SEQ ID NO:2. A mutant gene (SEQ ID NO:3) in which the coding sequence lacks an 11-base pair consecutive sequence (SEQ ID NO:11) of the sequence encoding bovine protein having myostatin activity has been sequenced. It has been shown that cattle of the Belgian Blue breed homozygous for the mutant gene lacking myostatin activity are double-muscled. A method for determining the presence of muscular hyperplasia in a mammal is described. The method includes obtaining a sample of material containing DNA from the mammal and ascertaining whether a sequence of the DNA encoding (a) a protein having biological activity of myostatin, is present, and whether a sequence of the DNA encoding (b) an allelic protein lacking the activity of (a), is present. The absence of (a) and the presence of (b) indicates the presence of muscular hyperplasia in the mammal. [less ▲]

In the production of sulfuric acid by (a) oxidizing a sulfurous material with an oxidant to obtain sulfur dioxide, (b) catalytically oxidizing this with oxygen to obtain sulfur trioxide and (c) producing sulfuric acid and a waste gas, at least part of the waste gas is recycled to the first step. The fabrication of sulfuric acid consists of: (a) producing sulfur dioxide from a sulfur based material and an oxidant; (b) converting catalytically the sulfur dioxide into trioxide in a catalytic converter fed with oxygen; and (c) producing sulfuric acid from the sulfur trioxide. In the last step, some other gases are also produced which are (partially) recycled into the oxidant used in step (a). An Independent claim is also included for apparatus for performing the process. The apparatus for H2SO4 production consists of: (a) production unit (10') of SO2 from a sulfurous raw material and an oxidant; (b) catalytic converter (20') of SO2 equipped with means of feeding O2; and (c) preparation unit (30') of H2SO4 from SO3 It comprises also means for recycling waste gases at the outlet of the preparation unit (30') of H2SO4 towards the SO2 production unit (10').

The method comprises the steps of prepg. the labeling agent, labeling a precursor in the form of a protected substrate, pre-​purifying and deprotecting same, and forming a final soln. of the resulting compd. The deprotection step, in which the labeled precursor is converted into a labeled compd., is performed directly on a solid medium in a column or a cartridge. A device for synthesizing the labeled compd. according to said method is also disclosed. Thus, 2-​[18F]​fluoro-​2-​deoxy-​D-​glucose and 1,​3,​4,​6-​tetra-​O-​acetyl-​2-​trifluoromethanesulfonyl-​β-​D-​mannopyranose were prepd. [less ▲]
