Electrical appliance with the functions of a refrigerator for the preservation of food comprising a body (12), having a first internal portion (16) able to define a finished internal shape of the refrigeration compartment and a first external portion able to define an external shape of the electrical appliance with the functions of a refrigerator, and a door (29) to close the refrigeration compartment. The door has a second internal portion able to define at least an internal compartment and a second external portion able to define an external shape of the door (29). The first internal and external portions and/or the second internal and external portions comprise reciprocal rapid attachment means, made in one piece, and able to stably couple the first internal portion to the first external portion so as to obtain the body (12), and/or the second internal portion to the second external portion so as to obtain the door (29).
Electric connector, able to connect to two parts of an electric circuit, comprising a pair of semi-connectors (12,14), made of plastic material able to be mechanically coupled to form a single body. Each semi-connector (12,14) has a mating terminal coupling form (16), at least a metal terminal (20), fixed internally to a first semi-connector (12) of the pair of semi-connectors (12,14), and able to be connected to a corresponding metal terminal (20) of the second semi-connector (14). Each semi-connector (12,14) comprises at least an electric cable (26), and a first packing element (34), able to exert a tight-sealing on the cable (26) and disposed annular on the cable (26). The first packing element (34) is made in a piece with each semi-connector (12,14).
A kit (10) for collecting blood, preferably peripheral blood, for the production of pluripotent stem cells comprises at least a first container (12), able to contain the blood taken, which contains an anticoagulant and the substance MCSF (Macrophage Colony Stimulating Factor).
Submerged port (10) for craft (11) also suitable to navigate underwater, comprising a containing structure (12) at least partly immersed in the water and defining inside it a chamber (13) to house the craft (11) and accessible from the outside through an aperture (14). The chamber (13), at least in its operating condition, comprises an upper compartment (15), dry, in which the craft (11) is in an at least partly emerging condition, and at least a lower compartment (16) immersed in the water, in which the craft (11) is in a condition of total immersion in the water. The aperture (14) is made on the containing structure (12) in a position such as to be, during use, always at least partly immersed in the water, and such as to put the lower compartment (16) in communication with the outside of the containing structure (12).
Method for the expansion of adult stem cells from blood, particularly but not only peripheral blood, comprising a first step of expansion of the stem cells of blood, immediately after they have been taken, by means of the in-vitro treatment with MCSF in a concentration comprised between 8-15 nM and a second step of purification of the expanded stem cells.
