Se han utilizado herramientas computacionales para proponer moléculas derivadas de cefalosporinas con potencial actividad antibacteriana, frente a cepas de Escherichia Coli, con mayor afinidad como inhibidores de enzimas de unión a penicilinas y que a su vez disminuyan o no tengan afinidad por betalactamasas de espectro extendido. Se diseñaron 20 moléculas con base en la estructura molecular de la cefalosporina, las estructuras fueron optimizadas utilizando la teoría del funcional de la densidad, se calcularon descriptores moleculares de reactividad, de forma paralela se sometieron a acoplamie

Abstract:
So far, diagnosing on candidiasis has still been limited in standard blood culture. The traditional method of this microbiology culture is less sensitive, many patients with candidasis infection have negative blood culture, and need a long time. This case encourage many researchers to use another alternative methode to diagnose. The purpose of this research is to examine the potency of Candida albicans protein extract as bioreseptor on immunocencor to detect Candida albicans and its biofilm in the blood of candidiasis patients. The research method which is used is descriptive with the followin

Abstract:
Muchos fármacos de uso común se han asociado con casos de hipovitaminosis. La vitamina B6 (piridoxina), ha sido una de estas vitaminas. El mecanismo mayormente propuesto para hipovitaminosis B6 inducida por fármacos es la inhibición de la piridoxal quinasa, enzima fundamental para la conversión de la piridoxina a su forma activa, fosfato de piridoxal (PLP). En el presente trabajo se estudió mediante cálculos de acoplamiento molecular, la posible interacción entre un grupo de fármacos de uso común (cicloserina, dopamina, isoniazida, levodopa, penicilamina, teofilina, muzolimina y progabida) y l

La demanda por el agregado de valor a los productos de origen agropecuario ha generado interés sobre la preservación de productos mínimamente procesados (PMP). La vida útil de los PMP es disminuida por la reacción de pardeamiento enzimático, la cual causa una pérdida en la calidad del alimento. En el presente trabajo se estudió el efecto de la adición de compuestos químicos sobre el contenido de ácido ascórbico, fenoles totales, la actividad de la enzima PPO y el color de los PMP de papa (Solanum tuberosum L.).

Diabetes mellitus is one of the endocrine metabolic disorders that has caused morbidity and mortality worldwide. Α-glucosidase inhibitor which plays an important role in carbohydrate metabolism is needed to avoid postprandial hyperglycemia. A bioactive peptide derived from soy protein was chosen as an alternative treatment for diabetes because of its therapeutic potential. Several bioactive peptides have been shown to inhibit the α-glucosidase enzyme, such as the bioactive peptide LLPLPVLK, SWLRL, and WLRL.
