摘要:
The present invention refers to a hybrid system for generating electric power used in an electrolysis process for obtaining metals, according to which the integration of two or more sources of electric current occurs, one of which being the grid (SIN) and the others being distributed generation sources, connected to the load supply node, with control of the total direct current to be injected in the load of the process. The renewable or non-renewable distributed generation sources may be: solar photovoltaic, concentrating solar, wind, fossil fuel generator, diesel generator, steam turbines, combined cycle plants etc. The power generation system may be used in an electrolysis process for obtaining metals such as zinc, copper, aluminum or nickel.

There is no description in the state of technique of a formulation, application or product of D-Ala 7 -Angiotensin-(1-7) (A-779) and analogues and derivatives, D-Pro 7 -Angiotensin-(1-7) and analogues or derivatives or of Ang-(1-7) analogues or derivatives using cyclodextrines, liposomes, biodegradable polymers and its derivatives for the study or treatment of arterial hypertension and other cardiovascular diseases and its complications, wounds, burns, erithema, tumors, diabetes mellitus, sperm mobility, nephropathy, gastrointestinal and gynaecological disorders, angiogenesis, angioplatsy, alopecia and blood diseases in animals of warm blood, or as ligands for de G-protein-coupled receptor MAS. This characterizes the present invention as a more effective option for the study and treatment of pathologies associated or not to this receptor. The present invention is characterized by the combination of two different technologies: the molecular encapsulation of the peptide Angiotensin-(1-7) and its analogues and derivates in cyclodextrin and the microencapsulation in biodegradable polymers and liposomes. It is also characterized by the increase of this peptide and its analogues and derivatives using the formulation of the present invention.

This invention is characterized by the preparation of composites made from bioceramics containing calcium salts like Ca5(PO4)3OH, CaCO3, CaSO4, Ca3(PO4), CaOSiO2(NO3)2, Ca10(PO4)6(OH)2, according to patent BR 10 PI9104220-8, (2000), natural and/or synthetic biodegradable or non biodegradable polymers, calcium phosphate cements, either natural or synthetic containing encapsulated or non- encapsulated micro or nanoparticulated antibiotics and angiotensin (1-7) in the form of suspensions, cosmetics, grafts and uses of such compositions in the process of tissue restitution. The composites containing antibiotics and angiotensin (1-7) can be used as grafts in humans and as veterinary medicinal products effective both as antibiotic and osteoconductor. Another feature of this invention is the use of tetracyclines in the composites, in concentrations that may vary from 0,001 % to 5%, effective as anti-inflammatory. The bioceramics/polymer composites claimed in this document display the induction properties of the repairing dentine, formation of compact dentine bridge.
摘要:
The present invention provides isoformes from a peptide family belonging to South American scorpion Tityus serrulatus that acts as hypotensive agents by potentiating Bradykinin and, therefore, can be used as anti-hypertensive drugs. A peptide was firstly isolated from Tityus serrulatus venom and showed a strong and long-lasted hypotensive activity when tested in rats. This peptide was first named TsHpt-I (Tityus serrulatus Hypotensin-I). Also, three more highly similar isoformes were identified and revealed a peptide family with very close primary structure. They were named TsHpt-II, TsHpt-III and TsHpt-IV.
摘要:
The present invention relates to a method and kit of detecting antibodies in the serum of animals infected with equine infectious anemia virus using the immunodiagnosis with the recombinant viral antigen gp90. The antigen was bound to solid supports (microtitter plates, tubes, beads or nitrocelullose papers or nylon) and reacted with clinical samples. After incubation with conjugated (Anti-equine immunoglobulin-enzyme) the reaction was revealed with a solution composed of the substract of the enzyme used in the conjugate (cromogene). After development of the reaction (color formation) it was stopped with acid solution and measured. The immunoassay may be a direct second antibody immunoassay, and one or two step sandwich immunoassay.
摘要:
The invention provides a new human interferon (IFN)-beta variant cloned from an amniotic cell library, a cDNA encoding it, and processes for its production and purification. The variant, termed interferon beta-cis, differs from previously known hIFN-beta isoforms by the substitution of a Cys residue for the Tyr present at position 60. Recombinant IFN beta-cis exhibits antiviral activity characteristic of IFN-beta.
摘要:
The present invention relates to a probiotic cosmetic formulation for the cosmetic treatment of the skin, comprising a microbiota and a cosmetically acceptable carrier. Preferably, betaines and/or prebiotic agents may be incorporated into said formulation. The invention also relates to the use of a microbiota in preparing said probiotic cosmetic formulation of the invention, and a method for the cosmetic treatment of the skin, which comprises administering to the skin of an individual the probiotic cosmetic formulation of the invention.
摘要:
The present invention relates to a synthetic peptide of 19 amino acids, called PnTx(19), constituted from the sequence of the native toxin PnTx2-6 of the Phoneutria nigriventer spider. It also relates to pharmaceutical compositions containing such a peptide and to the use thereof in the treatment of erectile dysfunction and/or in potentiating the erectile function.
