Patent CA-2261622-A1 (CA)
Inventor: PEREGRIN GONZALEZ GERARDO
IPC: A01G31/00
Filed: 1997-01-24
Abstract: A succession of suspended conduits are arranged on filiform and parallel supports (2). The upper sheet (1) has holes (6) for planting the respectives plants, the lower sheet (3) without holes acts as a collector, and the intermediary sheets (4) have the same number of holes which are offset longitudinarily with respect to the upper sheet (1). The conduits are assisted by the tube (8) forthe supply of water and nutrients and temperature control.  From said tube a microtube or similar comes out above the upper sheet, one for each watering unit, for its individual supply. The liquid comes down in cascade through the conduits and through the holes (7, 7') down to the lower conduit (3), and guides the roots of the plants through the same path as the nutrient.

Patent CA-2283753-A1 (CA)
Title: Micropathological patient replica based on unadulterated whole blood
Inventor: BARNES JANICE S
IPC: C12N5/078
Filed: 1998-03-20
Abstract: A patient replica is created from a layered culture medium where solid culture medium is formed so that a discontinuity exits between and contiguous with two of the layers of culture medium. An infusion port is provided in registration with the discontinuity so that a fresh unadulterated sample of patient blood can be infused into the discontinuity to form a thin layer of blood contiguous with the surrounding layers of culture medium. The thin layer obviates the requirement for any anticoagulant alloying blood-borne pathogens to be readily cultured without using broth. Further antibiotics or other drug samples may be placed on the surface of the culture medium above the blood layer so that the antibiotic can diffuse through the culture medium and reveal the sensitivities of the cultured pathogens. Other samples of pathogens or tissues can be placed on the exposed (upper) surface of the culture medium so that effects of drugs or growth factors present in the patient blood can be observed thereby allowing the entrapped blood layer to act as a biological replica of the patient.
