Emodin, Physcion, and Crude Extract of Rhamnus sphaerosperma var. pubescens Induce Mixed Cell Death, Increase in Oxidative Stress, DNA Damage, and Inhibition of AKT in Cervical and Oral Squamous Carcinoma Cell Lines. [PDF]
Oxid Med Cell Longev, 2018 There have been few studies on the pharmacological properties of Rhamnus sphaerosperma var. pubescens, a native Brazilian species popularly known as “fruto‐de‐pombo.” The aim of this study was to investigate the scavenging capacity of emodin, physcion, and the ethanolic crude extract of Rhamnus sphaerosperma var.

Protective and antioxidant effects of a chalconoid from Pulicaria incisa on brain astrocytes. [PDF]
Oxid Med Cell Longev, 2013 Oxidative stress is involved in the pathogenesis of neurodegenerative diseases such as Parkinson′s and Alzheimer′s diseases. Astrocytes, the most abundant glial cells in the brain, protect neurons from reactive oxygen species (ROS) and provide them with trophic support, such as glial‐derived neurotrophic factor (GDNF).

SustainabilityThe ongoing biodiversity crisis, driven by human activity, climate change, and disease spread, is reflected by the rapid decline of animal populations across all phylogenetic groups. Bats exemplify a group highly susceptible to these threats. While threats to bats are often studied locally, global interactions remain overlooked.

Waveguide Metacouplers for In-Plane Polarimetry [PDF]
Physical Review Applied, 2016 The state of polarization (SOP) is an inherent property of the vectorial nature of light and a crucial parameter in a wide range of remote sensing applications. Nevertheless, the SOP is rather cumbersome to probe experimentally, as conventional detectors only respond to the intensity of the light, hence loosing the phase information between orthogonal ...
