The development of multifunctional materials for bone tissue repair has attracted researchers' interest. Several classes have been studied and optimized this aim, such as implants based on metals, ceramic, glasses, composites. Among these is hydroxyapatite (HAp), a popular scaffold used the main constituent several biomaterials. HAp presents good biocompatibility, osteoconduction, non-toxicity, porosity, adequate mechanical properties. Nevertheless, to improve its properties or add novel...
Water contamination represents a significant ecological impact with global consequences, contributing to water scarcity worldwide. The presence of several pollutants, including heavy metals, pharmaceuticals, pesticides, and pathogens, in resources underscores pressing concern, prompting the European Union (EU) establish Watch List monitor level these substances. Nowadays, standard methods used detect quantify contaminants are mainly liquid or gas chromatography coupled mass spectrometry...
Quantum dots (QDs) are semiconductor nanocrystals, which present unique photophysical properties, enabling their application as new fluorescent platforms for biomedical sciences.Colloidal QDs end-capped with organic or inorganic compounds, not only to prevent agglomeration but also provide reaction sites the attachment of targeting (bio)molecules, nanoparticles other interfaces, specific biological purposes.The (bio)conjugation can involve non-covalent covalent interactions, be accomplished...
Supramolecular hydrogels rely on small molecules that self-assemble in water as a result of the cooperative effect several relatively weak intermolecular interactions. Peptide-based low molecular weight hydrogelators have attracted enormous interest owing to simplicity combined with versatility and biocompatibility peptides. In this work, naproxen, well known non-steroidal anti-inflammatory drug, was N-conjugated various dehydrodipeptides give aromatic peptide amphiphiles resist proteolysis....
As organizações públicas enfrentam pressões crescentes por mais eficiência e transparência, sobrecarregadas dentro de um contexto grande volume dados, mudanças constantes situações adversas. Esse cenário exige das maior agilidade na tomada decisão investimento em soluções tecnológicas que auxiliem a gestão pública ser eficiente transparente. O objetivo deste estudo foi levantar as evidências quanto utilização painéis indicadores, tipo Business Intelligence (BI), no da brasileira, destacando...
Este artigo tem por objetivo analisar a epidemiologia das internações esquistossomose no Brasil período de 2014 2024. Trata-se uma pesquisa descritiva, transversal e epidemiológica. Os dados acerca foram obtidos através do Sistema Informações Hospitalares Departamento Informática Único Saúde (SIH/DATASUS), considerando o As variáveis analisadas incluíram sexo, faixa etária, raça, número ano. No analisado, registradas 1.813 Brasil. A análise dos revela um padrão geográfico demográfico...
Objetivo: Analisar os principais artigos disponíveis sobre o impacto que a suplementação de micronutrientes e alterações dietéticas tem nos pacientes com migrânea. Revisão bibliográfica: A migrânea é uma doença neurológica crônica cuja fisiopatologia ainda não está totalmente esclarecida, embora saiba-se da presença citocinas inflamatórias dos desequilíbrios iônicos. Como um tratamento alternativo ou complementar ao tradicional, magnésio, isoflavonas soja, nano-curcumina, ômega 3 isolado em...
Abstract Several N ‐acyl‐β‐hydroxyamino acids were prepared and treated with di‐ tert ‐butyl dicarbonate in the presence of 4‐(dimethylamino)pyridine, followed by treatment , N′ ‐tetramethylguanidine to give corresponding ‐acyldehydroamino good high yields. These then I 2 /K CO 3 1,8‐diazabicyclo[5.4.0]undec‐7‐ene. The methyl esters ‐acyldehydroaminobutyric acid gave substituted oxazoles ‐acyldehydrophenylalanines 5‐phenyloxazole derivatives low moderate yields together...
Abstract We have developed a modification of our previously reported high‐yielding method for the synthesis N , ‐diacyldehydroamino acid derivatives to prepare ‐monoprotected dehydroamino acids and dehydrodipeptides. Thus, several dehydroalanine, dehydroaminobutyric dehydrophenylalanine been prepared by treating corresponding L ‐serine, ‐threonine D ‐3‐phenylserine ( threo ‐type) with 1 equiv. di‐ tert ‐butyl dicarbonate 4‐(dimethylamino)pyridine. The reaction proceeded initial formation an...
Magnetic resonance imaging (MRI) is a powerful non-invasive diagnostic tool that enables distinguishing healthy from pathological tissues, with high anatomical detail. Nevertheless, MRI quite limited in the investigation of molecular/cellular biochemical events, which can be reached by fluorescence-based techniques. Thus, we developed bimodal nanosystems consisting hydrophilic quantum dots (QDs) directly conjugated to Gd(III)-DO3A monoamide chelates, Gd(III)-DOTA derivative, allowing for...
