A system (1) of smart tiles (2), comprising: - a plurality of tiles (2) arranged and mutually connected to form a grid (3), each object (2) comprising an electronic module that is electrically connected to the electronic module of each adjacent tile (2) by means of a point-to-point connection; - a control unit (4); - a plurality of interface devices (5), each configured to act as a communication interface between the control unit (4) and the electronic module of one of the tiles (2), wherein the control unit (4) is configured to: • obtain from the interface devices (5) data that are used to identify the topology of the grid (3) and the location of each tile (2) within the grid (3); • store the data in a graph-based data structure.
摘要:
Electronic system for detecting the margin between tumour mass in a tissue and healthy tissue, comprising an electronic processing unit (U) which controls a detection probe (2) with an elongated shape and which is traversable. This probe comprises at least one electromagnetic sensor in the microwave frequency range capable of obtaining the dielectric permittivity of the tissue.
摘要:
The object of the present invention is the provision of pharmaceutical formulations containing unsaturated and particularly polyunsaturated fatty acidis suitable for administration to humans and that have an acceptable organoleptic profile for topical, mucosal and oral administration. To obtain the desired fine emulsions it is used as a stabilizing agent a salt of chitosan-oleate. This agent has proved effective in the production of fine emulsions able to completely masking the poor organoleptic characteristics of polyunsaturated fatty acids. In such formulations it may also be added natural products and in particular essential oils.
摘要:
The present invention relates to a mutation of the catalytic domain of a NADPH oxidase (NOX) and the use thereof to facilitate crystal structure determination, and to the corresponding mutated form of NOX and the use thereof to design and produce chemical scaffolds for the generation of NOX ligands effective in different diseases.
摘要:
It is disclosed a two-photon excited fluorescence microscope comprising a laser source suitable for emitting a light beam and an optical arrangement suitable for receiving the light beam from the laser source. The optical arrangement is configured for shaping the light beam so that, at the output of the microscope, the light beam is substantially collimated in a first transverse direction perpendicular to the propagation direction of the light beam at the microscope output and is focused in a second transverse direction perpendicular to the first transverse direction and to the propagation direction, thereby forming a line parallel to the first transverse direction.
摘要:
The present invention discloses a new L-asparaginase from Helicobacter pylori. The recombinant enzyme cloned from Escherichia coli has been isolated, purified and characterized. It can be used as a new therapeutic and diagnostic tool. Further, its application as a food additive has been disclosed.

摘要:
The present invention relates to a method for estimating or predicting the anti-tumor activity of a compound and for estimating or predicting the tumor growth in mammals; the estimation of the anti-tumor activity of a compound administered to mammals developing a tumor comprises a) measuring the tumor weight in time; b) measuring the concentration of the compound in time; c) calculating, on the basis of said measures, the following kinetic parameters of the tumor growth: a parameter (L 0 ), representative of the portion of the tumor cells present at the instant t 0 =0 that succeeds in taking root and in starting the tumor cells proliferation in the mammals; an index (λ O ) of the production rate of the tumor cells during an exponential phase of the tumor growth; -an index (λ 1 ) of the tumor cells mass produced in the time unit during a linear phase of the tumor growth; and the following pharmacodynamic parameters of the compound: an index (K 1 ) of the tumor cells death rate; an index (K 2 ) of the potency of the compound; and d) calculating, on the basis of said kinetic and pharmacodynamic parameters, tumor growth curves. The invention, applicable in the pharmaceutical field, allows to make the best use of all the information generated during the preclinical studies and results to be sufficiently simple also allowing to get good estimates or predictions regardless of the uncertainties on the mode of action. The invention further allows to employ a small number of parameters, therefore avoiding time consumption as well as a number of mechanistic observations.
