Abstract

The invention relates to a capacitive pressure sensor (1) with reference capacitors (13, 13’), which comprises a vacuum-sealed hermetic cavity (12) disposed on an insulating layer into which are inserted a first sensor electrode (9) and two reference electrodes (10, 10’) that do not increase the total area of the sensor. A second sensor electrode (8) integrated into a flexible membrane covers the cavity (12). When an external force deforms the membrane, the capacitor (7) between the electrode sensors (8) and (9) varies, while the capacitors (13, 13’) between the electrode (8) and the reference electrodes (10, 10’) serve as a reference, so that the deformation of the membrane close to the electrodes (10, 10’) is minimal. The sensor also comprises two walls (11) that earth the electrode (8), thereby shielding the sensor against external electromagnetic interference. The method for obtaining the sensor allows the monolithic integration of same into microelectronic circuits.

Abstract

A novel transposon (TnC_T7) has been developed to partially supply the transcriptional machinery during the functional analysis of genomic/metagenomic libraries. This transposon was designed and constructed such that it can be integrated randomly into any episomal DNA, allowing the inducible expression of the adjacent DNA regions in both directions. In general, this genetic tool includes a kanamycin resistance gene, two T7 bidirectional promoters and the T7 RNA-polymerase-coding gene, the latter under the control of an arabinose-inducible promoter (PBAD). Experimental validation confirmed the potential of TnC_T7 for use in functional genomic/metagenomic studies in order to partially overcome the limitations of the bacterial hosts, which prevent same from recognising the majority of foreign genes in DNA libraries.

Abstract

Disclosed is a computer-implemented method that allows automatic discrimination between two tissues of interest: extrinsic tissue and intrinsic tissue, from a plurality of images, allowing a quantitative valuation of each of said tissues to be obtained without requiring the intervention of an expert. Said method involves: defining, using a parametric contour, a discrimination area in images obtained from a medical image acquisition device; and subsequently discriminating and quantifying the tissues on the basis of the photometric features of the different tissues observed in the images, evaluating the local area of each voxel belonging to the discrimination area previously defined within the plurality of images. The disclosed method considerably increases precision in the discrimination and quantification of tissues, while the percentage error shown is considered tolerable for diagnostic purposes.

Abstract

The invention relates to a method comprising the mechanical and chemical treatment of the small intestine of a warm-blooded vertebrate, in order to remove the mucous, serous and muscular coats and to obtain the remaining submucous coat. In short, the jejunum portion of the small intestine is obtained from a recently deceased warm-blooded vertebrate and is stored at 4°C in 0.9% saline solution. Subsequently, longitudinal scraping is performed for the initial removal of the mucous coat and it is then washed until clean. The small intestine is cut longitudinally and both surfaces are scraped in order to remove the remaining mucous coat and the muscular and serous coats, until a translucent white membrane is obtained. This is then submerged in 0.9% saline solution or distilled water and washed for 30 to 120 minutes until the blood residues disappear, constantly stirring same and changing the water every 20 minutes. Scraping is performed once again in order to eliminate the last remanents of the serous, muscular and mucous coats. It is then exposed to a mixture comprising 0.5% sodium hypochlorite and 0.5% hydrogen peroxide for 15 to 40 minutes in order to eliminate the remaining cells, constantly stirring same and observing that no obvious structural changes occur. It is washed with a phosphate buffer solution for 15 minutes, stirring constantly, and subsequently washed with 0.9% saline solution or distilled water. The membrane obtained is shaped according to use. The membranes can be used individually or to form an aggregate of multiple stacked membranes depending on the desired strength and the membranes can be given particular shapes. Following shaping, the membranes are dehydrated by means of exposure to a laminar sterile air flow. The entire method must be carried out in maximum asepsis conditions at ambient temperature. The membranes must be sterilised prior to implantation in a living organism. Said membranes can be used in maxillofacial surgery, reconstructive and plastic surgery, cardiovascular surgery, gastroenterology and urology, inter alia.
