GPX Knockdown Is Associated with Altered Redox Homeostasis, Plant Development, and DNA Methylation-Related Profiles in Rice

Pedro Alexander Velasquez-Vasconez · Marina de Lima Nogueira · Carlos Betancourth García · Claudia Elizabeth Salazar-González · y 1 más

Background: Glutathione peroxidases (GPXs) regulate peroxide detoxification and redox signaling, but their relationship with DNA methylation remains unclear in Oryza sativa. This study evaluated whether silencing mitochondrial GPX1 and GPX3 is associated with changes in growth, antioxidant activity, and DNA methylation...

Case Report: Shared decision-making in severe rheumatic mitral stenosis complicating pregnancy

Velásquez Trujillo, Luis Armando · Hurtado Rivera, Manuel Alejandro · Bucheli Enríquez, Víctor Rafael · Ayala Zapata, Sebastián · y 2 más

Severe rheumatic mitral stenosis (MS) is one of the highest-risk valvular lesions in pregnancy, and it becomes particularly hard to manage when the valve is unsuitable for percutaneous balloon mitral valvuloplasty (PBMV) and the patient declines termination. We describe a 20-year-old primigravida who presented at 23.5...

Non-native and invasive tree species are abundant in neotropical secondary forest but decline over time

Angélica F. Resende · Lourens Poorter · Fabio A. R. Matos · Frans Bongers · y 62 más

Non-native and invasive species are among the leading causes of global biodiversity loss and could therefore compromise the recovery of native forests after disturbance, such as on abandoned agricultural lands. Here we evaluated how the relative density and richness of non-native woody species (NNS) change across secon...
