摘要:
An electromagnetic waveguide, such as an optical fibre, including a hollow central core surrounded by a microstructured sheath formed by an assembly of elementary cells, the microstructured sheath also including at least two elementary cells, at least one intermediate element connecting the elementary cells, the intermediate element having a cross-section with an area less than or equal to 50% of the cross-sectional area of each of the cells that it connects, the intermediate element having a refractive index less than or equal to the refractive index of each of the elementary cells that it connects.
摘要:
Process for conferring a protection against a pathogen upon a plant by elicitation by an aqueous composition, the active agents of which are extracted from edible fungi (parasol mushroom, pleurotus, button mushroom). An alkaline extraction is carried out, then an enzymatic hydrolysis, to obtain a fraction less than 100 kDa. The process consists in spraying the aerial parts of the plant with the composition obtained in this way; this thereby acts to combat cryptogamic diseases of plants such as vines, fruit trees, vegetable crops and cereals.
摘要:
A field of waveguides is disclosed. A tubular electromagnetic waveguide includes a hollow central portion defined by a first set of at least seven primary hollow tubes that are distributed annually about the hollow central portion, and a second set of tubes including at least one secondary hollow tube; when there are a plurality thereof positioned annularly around the primary hollow tubes the area of the at least one secondary hollow tube is comprised between 0.35 and 0.50 times the area of the hollow central portion. The hollow tubes of the first set are substantially of same size and distant from one another.

The present invention relates to an recombinant nucleic acid molecule comprising an immunoglobulin heavy chain variable region (VH), an immunoglobulin light chain variable region (VL), an immunoglobulin light chain constant region (CL), an immunoglobulin heavy chain constant region (CH) corresponding to the CH1, hinge, CH2 and CHS protein domains encoded by the human pseudo-gamma gene (ψγ), and its uses for therapeutic or diagnostic purposes. The invention further relates to an antibody encoded by said recombinant nucleic acid molecule, and an expression cassette, vector, viral particle, host cell, transgenic organism or pharmaceutical composition comprising said recombinant nucleic acid molecule.
摘要:
A generating device includes at least one pulsed laser source that delivers primary photons having at least one wavelength in a single spatial mode and in pulses having a high pump energy, forming means that act on the primary photons to deliver an input beam, and at least one optical fiber having at least ten modes between which the pump energy is initially distributed, and able to relocate the latter via a non-linear effect into a fundamental mode, before generating secondary photons of various wavelengths by wavelength conversions from the wavelength of the primary photons in the fundamental spatial mode.
摘要:
The present invention concerns a treatment of diseases involving B cells, B lymphocytes or plasmocytes. In particular, it concerns an antisense oligonucleotide or a mixture of antisense oligonucleotides capable of inducing exon skipping at the RNA of the immunoglobulin heavy or light chains, for the use of same in the treatment of diseases involving B cells.
摘要:
An oligopeptide isolated from an SCO-spondin glycoprotein, characterized by the sequence: —W—S—X1—W—S— X2—C—S— X3—X4—C-G- (SEQ ID NO: 1), in which X1, X2, X3 and X4 represent amino acid sequences that consist of 1 to 5 amino acids. The oligopeptide may be used as a drug for inhibiting angiogenesis, in the treatment of diseases associated with angiogenesis in humans or animals, in particular against tumor angiogenesis. The oligopeptide is suitable in particular for the treatment of brain tumors.

摘要:
Disclosed is a method for manufacturing a green piece made of ceramic material by the technique of additive manufacturing according to which layers of a photocurable paste are successively allowed to cure by irradiation according to a pattern defined for each layer, the first layer being formed on a working surface on a working tray, each layer, before curing, being spread by scraping a paste mass provided on the working tray, which is lowered upon each formation of a layer. According to the disclosure, when spreading at least one of the photocurable paste layers, at least one scraping blade in working position, in addition to its scraping motion or so-called pass motion, is allowed to go back and forth in its plane, according to a so-called vibration motion.
摘要:
Method for determining, in vitro, the cell aggressiveness grade of cancer cells or for detecting cancer stem cells in a cell sample originating from a solid tissue suspected of being cancerous, includes: a) dissociating the cell cluster constituting the sample into a suspension of whole and viable isolated cells, b) macroscopically sorting the cells to obtain homogeneous subpopulations, c) calibrating at least one microwave electromagnetic sensor resonating at its own resonance frequency, d) presenting the dissociated and sorted cells to the calibrated sensor, e) interrogating the sensor and determining its new resonance frequency having received the cells, f) calculating the variation in overall dielectric permittivity of the cells according to the variation in working frequency, which constitutes the electromagnetic signature of the cells. The macroscopic sorting is without prior labelling and is based on the intrinsic properties of the cells. A kit for implementing the method is also described.
