摘要:
The present invention describes a process to form hydrazides from the reaction of a hydrazine and a dicarboxylic, using a Lewis acid as a main reagent of the reaction. The reaction occurs in a safe reactional environment, utilizing smooth conditions, neither involving high temperatures nor high pressures, producing the desired products with high yields, between 90-95%. The invention also describes a kit for utilization of chemiluminescent substances, comprised of two solutions.
摘要:
Polymer compositions may include a polymer matrix containing a polyolefin, one or more polymer particles dispersed in the polymer matrix, wherein the one or more polymer particles include a polar polymer selectively crosslinked with a crosslinking agent, and wherein the one or more polymer particles has an average particle size of up to 200 µm. Processes of preparing a polymer composition may include mixing a polyolefin, a polar polymer, and a crosslinking agent; and selectively crosslinking the polar polymer with the crosslinking agent in the presence of the polyolefin. Methods may include increasing stress cracking resistance of a polyolefin by mixing a polar polymer with the polyolefin; and selectively crosslinking the polar polymer in the presence of the polyolefin with a crosslinking agent to form crosslinked polar polymer particles dispersed in the polyolefin.
摘要:
The present invention generally concerns new non-agglomerating bioconjugates of amylin-mimetic compounds with polyethylene glycol, and their use mainly in the treatment of diseases associated with extracellular amyloid deposition or accumulation that contributes to the dysfunction or failure of systemic organs such as the pancreas.
摘要:
The invention relates to a method for promoting an exacerbated increase in vegetable biomass, in the order of 30 to 80% higher than that of non-transformed plants, by introducing a polynucleotide sequence into the genome of a plant of commercial interest. The sequence of SEQ. ID. No. 1 or the sequence of SEQ. ID. No. 2 code for a gene belonging to the anaphase-promoting complex, also called cyclosome (APC/C), and homologous, orthologous or paralogous sequences.
摘要:
Diabetes mellitus is a disease which, according to the World Health Organisation, is responsible for a significant proportion of deaths throughout the world. In spite of the large number of glycemic control products aimed at diabetes, there still exist pharmacological and pharmacokinetic gaps to be filled. The present invention aims at describing a method for developing a polymer system for encapsulating amylin and agonist analogues in the form of nanoparticles and microparticles. Another object of the invention is a method of functional in vitro evaluation of amylin released from polymer encapsulation systems. The invention further describes the use of the system for producing a medicament for amylin replenishment therapy in patients, which can be used for treating or preventing metabolic diseases.
摘要:
The present invention refers to a process of transesterification of mono-, di and triglycerides present in vegetable oils and animal fats, which are transesterified with alcohols of 1 to 3 carbon atoms making use of basic solid heterogeneous catalyzers, being the products of the reaction used as fuel or additive for fuel, as solvents, as intermediaries of tensoactives or as detergents .
摘要:
The present invention describes functionalizeds derivatives of ethyl 6-N- alkyl and/or 6-N-aryl ureas [1 ,3]dioxolo[5,4-g]quinolin-7-carboxylate (3a-z, 4a-z) and similar types (5a-z), of general formula (I, II, III and IV), useful in the treatment and/or prevention of inflammatory diseases, such as acute or chronic inflammatory conditions, different types of arthritis, asthma, Crohn's Disease and diabetes mellitus Type I, among others. These derivatives have the ability of modulate the inflammatory process, acting in mitogen activated protein kinase p-38 (MAPK-p38). Moreover, the derivatives of the present invention present expressive anti-inflammatory properties evaluated in in vivo models. The present invention also discloses processes for the production of such derivatives and harmaceutical com ositions containin the same.
摘要:
