Resumen

Este estudio desarrolló nuevas nanopartículas para mejorar la terapia quimiodinámica (CDT) para el cáncer de mama al aumentar los niveles de peróxido de hidrógeno (H2O2) y la eficiencia catalítica. La nueva plataforma theranostic ofrece capacidades de imagen dual para mejorar la visualización y el tratamiento del cáncer.

Área de la Ciencia:

Ingeniería Biomédica Ingeniería Biomédica.
Nanotecnología La nanotecnología es la nanotecnología.
Oncología Oncología.

Sus antecedentes:

El cáncer de mama es una de las principales causas de muerte entre las mujeres a nivel mundial.
La terapia quimiodinámica (TDC) es prometedora para el tratamiento del cáncer mediante la generación de radicales hidroxilo (•OH).
Las estrategias CDT actuales se enfrentan a limitaciones debido al suministro insuficiente de peróxido de hidrógeno (H2O2) y a la baja eficiencia catalítica in vivo.

Objetivo del estudio:

Desarrollar nanopartículas mesoporosas huecas azules prusianas (M-HMPB NPs) dopadas con metales de transición para mejorar la TDC.
Para integrar la glucosa oxidasa (GOx) para un doble efecto terapéutico mejorado.
Para crear una nanoplataforma teranostica integrada para el cáncer de mama con capacidades de doble imagen.

Principales métodos:

Las NP M-HMPB sintetizadas (MCo, Mn, Ni) cargadas con GOx. también se encuentran presentes.
Investigó el rendimiento catalítico en cascada entre HMPB y GOx para la generación de H2O2.
Se incorpora un tinte IR-808 para resonancia magnética y fluorescencia de doble imagen.

Principales resultados:

Los NP M-HMPB efectivamente entregaron GOx, mejorando la eficacia de la CDT.
Una reacción en cascada entre HMPB y GOx alivió la escasez de suministro de H2O2.
El nanosistema funcionalizado IR-808 demostró un rendimiento de imagen dual para la visualización terapéutica.

Conclusiones:

Los NPs M-HMPB desarrollados ofrecen un enfoque optimizado para la CDT en el cáncer de mama.
La nanoplataforma teranostica integrada proporciona capacidades terapéuticas y de imágenes duales.
Esta estrategia tiene potencial para avanzar en el tratamiento y diagnóstico del cáncer de mama.

Cancer Therapies

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Periodic Classification of the Elements

Periodic Classification of the Elements

The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Alkali Metals

Alkali Metals

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

Classification of Elements and Compounds

Classification of Elements and Compounds

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond. Elements are classified as atomic or molecular based on the nature of their basic units.
Compounds are pure substances composed of two or more elements in fixed, definite proportions. Compounds are classified as ionic or molecular (covalent) based on the bonds...
