Abstract: Disclosed is a scaffolding protein having SEQ ID NO: 1, derived from a conotoxin, which does not have amino acid residues associated with the toxic activity of the conotoxin and which can be used to generate chimeral proteins having 19-47 amino acids, fragments of a CDR3 of a vNAR with affinity for a specific antigen being inserted between amino acids 11 and 12 thereof.

Abstract: A method to increase the biomass production and fatty acids in the alga Chlorella vulgaris Beyerinck and obtain a lipid rich biomass type C:16 (palmitic), C18:1n-9 (oleic), C18:2n-6t (linoleidic) and C18:3n-3 (alpha-linolenic), which uses low irradiance from a dichromatic light source.

Abstract: The present invention relates to a novel vNAR protein of SEQ ID No: 1 capable of inhibiting the activity of VEGF in carnivorous mammals of the Canis and Felis genera, thereby inhibiting solid tumors growth of both genres.

Abstract: A protocol for the cryopreservation of high viscosity biological samples, preferably of spermatic samples of crustaceans or insects, that enables maintaining intact the physical properties of the original sample preserving the viability of the sperm packet.

Abstract: The present invention relates to processes for obtaining metal oxides by irradiation of low energy laser pulses of metal layers, wherein said metals can be formed as simple metals, alloys, or multilayers. The present invention performs the oxidation of a thin metal film deposited on a substrate; e.g., glass (SiO2) or silicon (Si) by a laser-irradiation time of a few nanoseconds to femtoseconds at high repetition rate, time necessary to achieve a stoichiometry and a well-defined microscopic structure. Through the processes of the invention, it is possible to obtain complex structures and metal oxides at room temperature in a very short time and with very low energy consumption.

Abstract: The invention relates to an isolated or recombinant protein from the shark Heterodontus francisci, which has bovine-erythrocyte-recognition activity and which can bind to sequences of antigens and/or proteins that are characteristic of infectious diseases. Once the aforementioned protein is bound to specific antigens of infectious diseases, it can haemagglutinate upon recognizing the bovine erythrocytes and antibodies characteristic of said diseases, which are present in the active state in biological samples such as whole blood, plasma or serum of bovine origin. The invention also relates to methods for protecting the detection of antibodies characteristic of infectious diseases, using the purified periplasmic extract or fusion protein, optionally purifying the recombinant protein.
