The invention relates to gas analysis and to combustible gas and vapour analyzers based on a thermocatalytic operating principle. The subject of the invention is a sensor the sensitive elements of which are manufactured by planar techniques that can be easily automated.

The sensitive elements are disposed in a reaction chamber having restricted diffusion access via a calibrated orifice, and the diameter of regular pores in the microchip substrate is increased to sizes that provide for a predominantly molecular diffusion mode in the pores (100 nm or more). |

Method for repairing defects on hot parts of turbomachines through hybrid hot isostatic pressing (HIP) process
In a hot isostatic pressing (HIP) method, the component to be treated, affected by imperfections, like porosity, cracks and cavities in its structure, is placed into a container together with non-metallic material in form of powder or grains having size greater than the porosity and the cracks and imperfections of the component. During the HIP process, the non-metallic material presses on the whole surface of the embedded component in order to generate a combination of temperature and forces capable to reduce defects, embedded and not embedded, in the component itself. The component is not contaminated during the process thus allowing easily removal of the non-metallic material by a simple operation of mechanical cleaning or chemical washing. |

Methods for diagnosing prostate cancer and predicting prostate cancer relapse
The present invention relates to methods and compositions for diagnosing prostate cancer and/or determining whether a prostate cancer patient is at increased risk of suffering a relapse, or a rapid relapse, of his cancer. It is based, at least in part, on the results of a comprehensive genome analysis on 241 prostate cancer samples (104 prostate cancer, 85 matched bloods, 49 matched benign prostate tissues adjacent to cancer, and 3 cell lines) which indicate that (i) genome copy number variation (CNV) occurred in both cancer and non-cancer tissues, and (ii) CNV predicts prostate cancer progression. |

Analysis kit, analyzer, and methods for analyzing template nucleic acid or target substance
The present invention provides a method for analyzing a template nucleic acid, a method for analyzing a target substance, an analysis kit for a template nucleic acid or a target substance, and an analyzer for a template nucleic acid or a target substance, which are excellent in accuracy. The method for analyzing a template nucleic acid of the present invention includes the steps of: fractionating a sample containing a template nucleic acid into a plurality of template nucleic acid fractions; amplifying a target sequence and its complementary sequence in the template nucleic acid with respect to each of the plurality of template nucleic acid fractions in the presence of a nucleic acid amplification reagent; detecting generation or quenching of a signal that shows an amplification of the target sequence or the complementary sequence with respect to each of the plurality of template nucleic acid fractions after the amplification step; and discriminating a template nucleic acid fraction in which the generation or quenching of a signal that shows the amplification has been detected among the plurality of template nucleic acid fractions as an amplified fraction in which the target sequence or the complementary sequence has been amplified, wherein the nucleic acid amplification reagent contains a primer set that amplifies the target sequence and the complementary sequence and a signal generating substance that generates or quenches a signal in response to the amplification, and the signal generating substance generates a signal in a state where it is bound sequence-dependently and quenches a signal in a state where it is not bound or quenches a signal in a state where it is bound sequence-dependently and generates a signal in a state where it is not bound, and generation and quenching of a signal are reversible. |
