摘要:
This invention relates to the isolation and characterization of an operon from the organism Xylella fastidiosa. This operon, referred to as the XfGUM operon, contains 9 genes, and is involved in the production of a compound with xanthan gum like properties. The expression products of the operon and genes are also a part of the invention, as are various uses of these.

The present invention relates to the use of the Pothomorphe umbellata extract to prepare dermocosmetic and/or pharmaceutical compositions for the treatment and/or prevention of photodamage in the skin, cutaneous aging and/or skin cancer. It also refers to der mocosmetic and/or pharmaceutical compositions for treatment and/or prevention of such photodamage in the skin, cutaneous aging and/or skin cancer prepared on basis of the defined extract. In addition, it provides a method of application of the dermocosmetic and/or pharmaceutical compositions prepared on the basis of the extract of this plant, in way to treat and/or prevent the damage caused to the skin by the excessive exposure to ultraviolet rays of the sun and to artificial tanning lamps.
摘要:
The purpose of the present invention is to provide a process for protection of enzymatic biocatalysts, constituted by a primary support, wrapped by a secondary matrix. More particularly, the invention is embodied as a bioreactor with a configuration that preserves the physical integrity and catalytic activity of the biocatalyst after long runs, and at the same time allows an easy separation of the protected biocatalyst from the solid, precipitated during the reaction course. Still more particularly, the invention refers to the use of the bioreactor herein described for the enzymatic synthesis of β-lactam antibiotics, including the insoluble enzymatic catalysts, which have a primary matrix for immobilization involved by a secondary matrix, which is able to preserve 100% of the catalyst physical integrity and approximately 100% of its catalytic activity.

摘要:
The present invention refers to uses of crotamine and compositions containing it, based on its characteristic of interaction with genetic material. Under submicromolar quantities, the polypeptide is no longer toxic, presenting the characteristics properties of cell penetration, transport of molecules to the surface, cytoplasm or cell nucleus and particularly, selective cell penetration. The invention also refers to compositions comprising a pharmaceutically effective concentration of crotamine and its use for the treatment of diseases and dysfunctions, based on its characteristics of interaction with genetic material, such as DNA and RNA, and cell selectivity. Further, the invention refers to a kit comprising crotamine as a reagent to: (i) transfect or carry molecules to the surface, cytoplasm or nucleus of the cell or (ii) identify and select actively proliferating cells in a mixed cell population, particularly the ones originated from the umbilical cord and/or bone marrow.
摘要:
The present invention refers to an ophthalmic instrument coupled to a Slit Lamp or Ocular Microscope (1) that utilizes imaging to selectively measure corneal curvature and examine its surface under examination mode of the instrument in reference, constituted of a ring or mask (2) projected by light, prisms and/or semi-transparent mirror, and an apparatus for observing the image reflected by the surface, which allows the passage of light reflected off the patient’s cornea through axes A and B, and indicates the eye to be measured, right or left.
摘要:
The present invention patent refers to the isolation and purification of peptides secreted by serpent venom glands, specifically Bothrops jararaca; to the peptide thus obtained, as well as to the production procedures by genetic engineering techniques in procaryotic and eukaryotic systems; to the engineered peptide thus obtained; to the production of said peptide by chemical synthesis, as well as to the peptide resulting from this chemical processing. It also refers to the utilization of said peptides, obtained by different procedures, in distinct pharmaceutical compositions, and introduced into the organism by a variety of means, in order for them to act as inhibitors of vasopeptidases, and consequently reduce systemic arterial blood pressure, and show local vasodilating action.
