Chenopodium quinoa, globally recognized as quinoa, stands out as one of the cereals with the highest nutritional value native to the Americas. It is cultivated in the Andes Mountain range, and Colombia is no exception, with the Boyacá department emerging as a significant quinoa-producing region. The quinoa ecosystem harbors a rich array of microorganisms within its rhizosphere.

Spasticity is a condition that profoundly impacts the ability to perform everyday tasks. However, its diagnosis requires trained physicians and subjective evaluations that may vary depending on the evaluator. Focal vibration of spastic muscles has been proposed as a non-invasive, pain-free alternative for spasticity modulation.

Article Synopsis
  • Bee colony health is being negatively impacted by pesticides, particularly imidacloprid, which affects queen bees and their reproductive success.
  • Exposure to imidacloprid led to significant cellular and structural changes in the midgut and ovaries of queen bees, potentially causing nutrient malabsorption and reproductive issues.
  • While the sperm morphology remained unchanged, the overall effects of imidacloprid on queen bee health could hinder both fertilization and colony growth.

Article Synopsis
  • This study examines the effectiveness of nitroxide radical-containing nanoparticles (RNPs) in preventing damage from reactive oxygen species (ROS) after cerebral ischemia-reperfusion in mice.
  • RNPs were compared to edaravone and a control group regarding survival rates, neurological outcomes, and their ability to protect the blood-brain barrier.
  • Results showed RNPs improved survival and neurological function more than edaravone, reduced blood-brain barrier disruption, and enhanced the beneficial M2 polarization of microglia, suggesting RNPs as a promising therapeutic option for neuroprotection.

Introduction: Free radicals and reactive oxygen species are related to deteriorating pathological conditions after head trauma because of their secondary effects. 2,2,6,6-Tetramethylpiperidine-1-oxyl (TEMPO) scavenges free radicals; however, this molecule is also toxic. Here, we have evaluated the neuroprotective effect of antioxidant nanoparticles, which consisted of a novel core-shell type nanoparticle containing 4-amino-TEMPO, that is, redox-active nitroxide radical-containing nanoparticles (RNPs).
