Abstract: Disclosed are isolated DNA constructs including (a) a first DNA sequence including either an inducible promoter sequence responsive to the presence or absence of an exogenous inducer or a developmental gene promoter capable of initiating gene expression in a selected tissue or at a selected stage of development of an organism; (b) a second DNA sequence including a DNA sequence coding for a protease enzyme operably linked and under the control of the promoter sequence specified at (a); whereby the presence or absence of the exogenous inducer or the activation of the developmental gene promoter specified at (a) results in expression of the protease enzyme. These constructs are preferably rendered reversible by the presence of further elements. These constructs can be used in plant or mammalian cells for disruption of cell function, controlling senescence and modifying the metabolism of stored proteins.

Abstract: Label intended to go around a skein of yarns or the like, which comprises a projecting part extended by a tab which can be folded down inside a loop of the said skein so as to neatly separate of the said yarns by creating the said loop in a permanent way, and to limit any relative slip of the label with respect to the said skein

Abstract: A promoter comprising the DNA sequence of an oil seed rape cysteine protease gene promoter of class 1, 2 or 6 is described. The promoter may be used in an expression system for at least the tissue or tissues of a germinating seedling or developing grain or plant (e.g. in the root, cotyledons, leaves and stem). In a preferred embodiment, the expression system comprises a disrupter gene fused to a promoter according to the present invention.

Abstract: A respiratory mask adapted to be fit against the face of a user is provided with a demand regulator connectable to a pressurized respiratory gas source. An extensible harness, having end portions connected to said mask, includes an inflatable element. A manually actuatable valve delivers pressurized respiratory gas from the source to the inflatable element to extend the harness when actuated and reduces the pressure in said inflatable element to retract said harness and to cause the mask to engage the face of the wearer when released. A sensor delivers an information representative of a force with which said mask engages the face to a valve for automatic control of exhaust of pressurized gas to atmosphere and admission of pressurized gas from the source, upon release of the manually actuatable valve to adjust the reduced pressure and to maintain the force at a value which is lower than the force exerted when the inflatable element is at an ambient pressure.

Abstract: A transport assembly which is particularly suitable for transporting medical material, particularly organs and tissues. The assembly includes a tissue container which includes a lid having a clamping assembly associated therewith for clamping an organ. In addition, a reservoir bag and collector bag are respectively connected to the tissue container, such that a physiological fluid can be pumped from the reservoir bag to the tissue container, and with fluid exiting the tissue container gathered in the collector bag. A support holder is also provided, and the support holder, tissue container, collector bag, and reservoir bag can be detachably placed in a box for transport.

Abstract: The container with a thermally insulated enclosure (100) is equipped with a refrigerating unit (20), with a pumping unit (30), with a control unit and with an electrical power source. This container also comprises a disposable aseptic detachable transporting assembly (60) together with a reservoir bag for a physiological fluid, a collector bag for gathering this fluid, a vessel for transporting an organ with a device for suspending the organ, a fluid dispensing element and pipework (66) for connecting this reservoir bag, dispensing element, vessel and collector bag by passing via the pumping unit. Application for the preservation and transporting of live organs to be transplanted.

Abstract: The disclosure pertains to X-ray tubes and, more particularly, in these tubes, it pertains to rotating anodes. The disclosed anode for an X-ray tube has a body or substrate on which a target is formed by a layer of target material, wherein the body comprises at least two parts formed by a first material, these two parts being connected to each other by a layer of a second material having greater plasticity than that of the first material.

Abstract: The apparatus is an anode for an X-ray tube which is rotated at high speeds during operation. The anode include a plate of refractory material with high mechanical strength. On both faces of the plate are fixed two blocks of light weight refractory material. One of the blocks is formed of several sub-blocks fixed to one another through brazing. A layer of X-ray emitting mattering is deposited on the outer surface of these sub-blocks.

Abstract: The invention relates to compounds based on saturated polyester and cross-linking agent. The compositions comprise a saturated polyester with terminal hydroxyl groups and a cross-linking agent consisting of a dianhydride with ester groups, the product of reaction between a trimellitic anhydride and a diol. Use of the compounds as a binder for powder paints applicable to the automobile, electrical household goods, agricultural machinery and lead industries.

Abstract: A plastics mesh structure comprises continuous filaments in the longitudinal direction and discontinuous connecting strands in the lateral direction.
