Abstract

The method of manufacturing a multilayer microfluidic device for the conduct of tissue culture under dynamic conditions is presented, which consists of at least six layers (these are: bottom and lid, adhesive layer, at least one auxiliary glass layer, at least one elastomeric functional layer and at least one hydrogel layer). The method is characterized by the fact that in the first stage, on the basis of pre-designed maps of each layer of the device, its elements (vascular and connecting channels and microchannels, inspection, positioning and through holes, culture chambers, partitions and tanks) are produced. For this purpose, elastomeric layers are prepared in such a way that the medium is coated with a layer of elastomer and fixed. Then the focused laser beam does the engraving and cuts the structures. The auxiliary glass layers, the adhesive layer and the bottom and lid of the microdevices are engraved and the structure are cut by means of a focused laser beam operating on material sheets. In the second stage, non-adhesive auxiliary glass layers and elastomeric functional layers are combined into sets. Each set consists of one glass layer and one elastomeric layer on a carrier which forms the temporary basis of the set. In the third stage, the previously prepared liquid hydrogel is introduced through inspection holes into the culture chambers of the sets where it is fixed and then disconnected from the temporary base of the unit. In this way, in the exposed hydrogel layer, vascular microchannels are engraved, whereas connecting channels are engraved in partitions, by means of a focused laser beam. In the fourth stage, without the use of glue, one or more sets are joined together or to the bottom or to the lid by means of an adhesive layer. In the fifth stage, the microsystem is combined with liquid supply and outlet hoses using an adhesive. In the sixth stage, the microsystem is cleaned and washed. In the seventh stage, suspension of cells of any type is introduced into the microsystem, once or several times, at intervals allowing their immobilization on the surface of microchannels. In the eighth stage, cell culture is carried out under flow conditions in order to form a network of capillary vessels within the artificial tissue.

Abstract

The method is that the infusion is stopped with temporary values of intracranial pressure while in the increasing phase, and when the intracranial pressure values are higher than those determined by the inflexion point tp, and also after the inflexion point value is exceeded, and in addition the inflexion point tp on a curve created by temporary values of the intracranial pressure in the increasing phase, is described by the formula: where: tp is the time at which the inflexion point occurs on the intracranial pressure curve in the increasing phase; whereas the intracranial pressure after the infusion has been stopped in the descending phase, is expressed by the following formula: where: ICP02 is a reference pressure of the cerebrospinal fluid in the descending phase, E2 is an intracranial elastance coefficient in the descending phase, RCSF2 is a resistance of the cerebrospinal fluid reabsorption in the descending phase, and then, from temporary values of the intracranial fluid pressure ICP(t) in the descending phase, the reference pressure of the cerebrospinal fluid ICP02 in the descending phase is determined, as is also E2/RCSF2 the quotient of the intracranial elastance coefficient E2 divided by the resistance of the cerebrospinal fluid reabsorption RCSF2 in the descending phase. The system consists of the intracranial pressure sensor (3) through a pressure transducer (4) that converts pressure into an analog signal, and through an analog-to- digital converter (5), is connected to a digital signal recording and processing system (6), and the infusion pump (2) is also connected to the digital signal recording and processing system (6).

Abstract

The secondary electron detector unit for a scanning electron microscope is mounted in a head body (1). In the lower part of the head body (1), a lower throttling aperture (2) is placed. Above the lower throttling aperture (2), the microporous plate (3) is sealed in the head body (1) by a gasket (5) and fastened with the use of the frame plate (6) which has an opening that exposes the active input area (7) placed asymmetrically with respect to the axis of the scanning electron beam (WE). Above the microporous plate (3), the scintillator (11) and the light pipe (12) are fixed at the side of the head body (1).
