Soilscapes from Byers Peninsula, Maritime Antarctic: landform-lithology controls in soil formation.

The Byers Peninsula, the largest ice-free area in Maritime Antarctica, is vital for studying landscape-scale natural processes due to its diverse periglacial landforms. This study aim to characterize the soils and environments of its southern sector, focusing on soil-landform-lithology interactions. Thirty-seven soil profiles were classified, collected, and chemically and physically analyzed.

Molecular analysis of zoonotic pathogens in free-ranging six-banded armadillos (Euphractus sexcinctus) from the Brazilian semiarid region.

This study investigated infection by Leishmania spp., Leptospira spp., Toxoplasma gondii, and Trypanosoma cruzi in six-banded armadillos (Euphractus sexcinctus) from the semiarid region of northeastern Brazil.

Nurses' practical contributions to improving healthy and sustainable public spaces: an integrative review.

Objective: to identify knowledge production about nurses' contributions to improving healthy and sustainable public spaces.

Methods: an integrative review carried out in February 2023 in electronic databases. Studies that answered the research question and that were available in full, in Portuguese, English and Spanish, were included.

A Disposable Pipette Extraction-UHPLC-MS/MS Method Based on Removal of Phospholipids to Determine Anandamide, 2-Arachidonoylglycerol, Cannabidiol, and Δ-Tetrahydrocannabidiol in Plasma Samples.

Cannabidiol (CBD) and Δ-tetrahydrocannabinol (THC), the main components of Cannabis sativa plants, can interact with specific cell receptors known as cannabinoid receptors (CBs). The endogenous compounds anandamide (AEA) and 2-arachidonoylglycerol (2-AG) are CB agonists, and, alongside enzymes, they constitute the endocannabinoid system (ECS) and take part in neuromodulation. Several LC-MS/MS methods have been developed to quantify these compounds in biological matrixes, but a fast and simple method that can determine these analytes in plasma samples simultaneously is not available.

Exploring high molecular weight components in Tityus serrulatus venom.

Our study identified high-molecular-weight compounds from Tityus serrulatus venom (TsV), and most of them have not yet been well explored. TsV was fractionated using FPLC system with different columns, analyzed by SDS-PAGE, and characterized by MALDI-TOF/TOF. Our study showed that TsV contains several high-molecular-weight compounds, including CRISPs, metalloproteinase and hyaluronidase.
