Abstract

The invention refers to a method for simultaneous detection and quantification of Listeria monocytogenes, Salmonella spp. and Shiga toxin-producing Escherichia coli (STEC), from any kind of sample related to food production, including complex food matrices such as fish, meat, or fruit; or simple matrices such as water, or food contact surfaces. The method of invention allows specific quantification of the above-mentioned pathogens simultaneously thanks to specificity of designed primers for the qPCR reaction. It is also highly reliable because the method includes a system to adequately control the quantification of pathogens within the matrix. This system comprises the inoculation of samples with a known concentration of a transformed microorganism (host) carrying a chimeric sequence, acting as an internal control host for the whole process.

Abstract

The invention refers to a method for simultaneous detection and quantification of Listeria monocytogenes, Salmonella spp. and Shiga toxin-producing Escherichia coli (STEC), from any kind of sample related to food production, including complex food matrices such as fish, meat, or fruit; or simple matrices such as water, or food contact surfaces. The method of invention allows specific quantification of the above-mentioned pathogens simultaneously thanks to specificity of designed primers for the qPCR reaction. It is also highly reliable because the method includes a system to adequately control the quantification of pathogens within the matrix. This system comprises the inoculation of samples with a known concentration of a transformed microorganism (host) carrying a chimeric sequence, acting as an internal control host for the whole process.

Abstract

The invention relates to a magneto-centrifugal flotation cell for ore concentration which reduces water consumption. A disadvantage of conventional flotation cells is the use of a large amount of water, some flotation cells requiring at least 60% water. The present invention uses ore pulp with increased density and viscosity, owing to the application of an axial magnetic field, wherein the Lorentz force, which is the force exerted by an electromagnetic field that receives a charged particle or an electrical current, can be used. The solution is a cell which, in addition to the forces that usually act on conventional flotation cells, uses external forces which, in principle, produce synergy in the separation of ore particles that have different gravitational and magnetic properties.

Abstract

The present invention relates to the use of regenerative medicine in livestock farming, in particular to regenerative medicine for the care of livestock, and even more particularly to regenerative medicine in the care of milk-producing animals, including cattle. Specifically, the invention concerns a foetal mesenchymal stem cell (MSC) composition of allogenic origin, a treatment method and the use thereof in mastitis in milk-producing animals, including cattle, suffering from mastitis, to immunostimulate the animal, the MSC coming from foetal bovine adipose tissue. The composition can be administered via the intramammary route, exercising an immunomodulatory effect on the inflammatory response and strengthening antimicrobial activity against mastitis-causing pathogens in milk-producing animals with mastitis, thereby becoming an alternative to replacing and/or supplementing the use of antibiotics.

Abstract

This patent concerns a compact and portable system for real-time detection and location of electromagnetic emissions in the spectrum used by mobile devices (cell phones and Wi-Fi/Bluetooth devices). The principle of detection and location is based on phased array technology, which enables the synthesis of a directional radiation beam that can be electrically controlled in terms of both its shape and direction. This technology is used primarily in military and astronomical applications. The device also includes localization and control algorithms. This device will allow for detecting and locating electromagnetic emissions by means of an antenna beam scan within a field of view of 80×80 degrees. Once the detection and location have been established, the results are overlaid to a visual image captured by a video camera.

Abstract

The invention relates to a process for obtaining nanoparticles (NPs) of copper, specifically with a size between 10 nm and 50 nm. Specifically, a method is described for constructing NPs of metallic copper and subsequently decorating or coating with smaller NPs of secondary metal. Existing technologies for silicon-based solar cells use silver but never copper because the penetration of same into the substrate severely reduces the efficiency of the device. For electrical interconnections in microprocessors, other metals, mainly aluminium, are used, despite being less electrically conductive. Given the relatively high cost of silver, replacing silver with copper is economically interesting, especially if this also allows inkjet print technologies to be used.

Abstract

The present application is directed to a method and system for secure electronic communications using physically distributed security hardware and capable of operating by simulating a common or unitary HSM device. This is achieved by implementing the internal operations of the HSM using threshold cryptography on a set of internal nodes. In order to provide the necessary functionality, the keys and the required operations (such as the digital signature) are distributed among these nodes. In particular, the system provides digital signature capabilities through an efficient and modular application of Victor Shoup's schema referred to in the background. The digital signature process involves the steps of: 1) the signing agent receives a document to be signed and the alias of the key with which the document will be signed; 2) the signing agent place the document in the request queue; 3) the active nodes retrieve the request from the queue; 4) each node signs the request with its piece of key; 5) each node puts its partial signature in the response queue; 6) the signing agent receives the partial signatures and verifies them; 7) if at least k>n/2 valid partial signatures are received, the signature is validated and delivered to the client. Otherwise, an error message is generated.

Abstract

The invention is an ex vivo method for early detection of acute kidney injury in critical patients, which includes the measurements of fibroblast growth factor 23 (FGF23), klotho (KL) and erythropoietin (EPO) as biomarkers. These measurements are obtained from a venous blood sample or urine, and allow the determination of the following indicators: 1=([FGF23]p×[EPO]p); 2=([FGF23]p/[Klotho]p); 3=([EPO]p)/[Klotho]p); 4=([FGF23]p×[EPO]p)/[Klotho]p); where [X]p is defined as the plasma level of a specific molecule (X) which includes fibroblast growth factor 23 (FGF23), klotho (KL) or erythropoietin (EPO). If the value of the indicator 1, 2, 3, 4 or two or more thereof, is equal or higher than a cut-off point (10 U), the indicator and/or indicators allow the identification of patients with high risk of developing AKI, with a high sensitivity/specificity. Therefore high levels of the indicator are associated to a high probability of the presence/development of AKI, which allows to perform specific clinical interventions for patients with AKI. If the value of the indicator 1, 2, 3, 4 or two or more thereof, is lower than the previously mentioned cut-off point, the probability of presence/development of AKI is low, therefore patients require only standard treatment.

Abstract

The invention relates to a magneto-centrifugal flotation cell for ore concentration which reduces water consumption. A disadvantage of conventional flotation cells is the use of a large amount of water, some flotation cells requiring at least 60% water. The present invention uses ore pulp with increased density and viscosity, owing to the application of an axial magnetic field, wherein the Lorentz force, which is the force exerted by an electromagnetic field that receives a charged particle or an electrical current, can be used. The solution is a cell which, in addition to the forces that usually act on conventional flotation cells, uses external forces which, in principle, produce synergy in the separation of ore particles that have different gravitational and magnetic properties.
