ABSTRACT
OBJECTIVE: To describe the recent trends in Parkinson's disease mortality in Mexico during 2000-2020. METHOD: The adjusted mortality rate per 100,000 inhabitants was calculated using the direct method and the world standard population. Trend analysis was performed with the Joinpoint software. RESULTS: The average mortality rate was 1.26/100,000 inhabitants (SD: 0.09), and males showed higher mortality than females (M/F ratio=1.60). Older individuals ≥70 years old showed higher mortality rates than the rest of the age groups. During the period of study, a significant increase in mortality was observed from 2000 to 2005, while from 2005 to 2020 no significant trend was observed in all the studied groups. CONCLUSIONS: In Mexico, males and older individuals showed the highest mortality rates. The socioeconomic regions with high levels of wellness showed the highest mortality rates levels. Parkinson's mortality rate has remained constant since 2005 in Mexico.

Objetivo: Describir las tendencias recientes de la mortalidad por enfermedad de Parkinson en México durante 2000-2020. Método: La tasa de mortalidad ajustada por 100.000 habitantes se calculó mediante el método directo y usando población estándar mundial. El análisis de tendencias se realizó con el programa Joinpoint. Resultados: La tasa de mortalidad promedio fue de 1,26/100.000 habitantes (DE: 0,09) y los hombres presentaron mayor mortalidad que las mujeres (relación H/M = 1,60). Los individuos ≥70 años presentaron las mayores tasas de mortalidad que el resto de los grupos de edad. Durante el periodo de estudio se observó un aumento significativo de la mortalidad de 2000 a 2005, mientras que de 2005 a 2020 no se observó una tendencia significativa. Conclusiones: Los hombres y de mayor edad mostraron las tasas más altas de mortalidad. Las regiones socioeconómicas con mayor nivel de bienestar presentaron las tasas más altas de mortalidad. La tasa de mortalidad por enfermedad de Parkinson se mantuvo constante desde 2005 en México.(AU)

Cancer treatments continue to have many disadvantages. Reactive oxygen species, such as H2O2, in high concentrations, can cause cytotoxicity to cells, being even greater in cancer cells. One of the H2O2-producing enzymes is glucose oxidase; its application in cancer treatment should be explored. In this work, the extracellular expression of the mutated recombinant enzyme glucose oxidase was carried out in the eukaryotic expression system Pichia pastoris SMD1168, through the modification and optimization of the gox gene of Aspergillus niger to improve its expression in yeast and its purification. Also, the secretion signal of the alpha-mating factor from Saccharomyces cerevisiae was added to the gene for extracellular expression, and it was inserted into the expression vector pPIC3.5k. The extracellular expression of the enzyme facilitated purification by anion exchange chromatography; the purification was corroborated by SDS-PAGE, with a molecular weight of its subunit between 63 kDa and 100 kDa. The mutated recombinant enzyme glucose oxidase showed greater anticancer activity compared to the commercial glucose oxidase and could have potential for cancer treatment. KEY POINTS: ⢠Pichia pastoris is an excellent eukaryotic expression system for proteins that need post-translational modifications. ⢠Extracellular expression facilitates protein purification. ⢠Glucose oxidase has potential application in cancer treatment.
