Article Synopsis
  • Harmful algal blooms (HABs), especially those from toxin-producing microalgae like Prorocentrum micans, are a recurring issue in Patagonian fjords, and a significant HB-HAB occurred in Northwest Chilean Patagonia during February-March 2022.
  • Observations showed a dramatic increase in P. micans cell density from low levels in January to a peak of over 8.3 x 10 cells/mL by mid-February, associated with warmer sea temperatures and varying salinity.
  • Satellite images and oceanographic modeling revealed that water currents and temperature variations in the Gulf of Ancud supported the development and maintenance of this harmful algal bloom, indicating a hotspot for both HABs and HB-HAB

Article Synopsis
  • Coral reefs are declining due to human activities, prompting restoration efforts like outplanting corals to help recover these ecosystems.
  • Understanding how outplanted corals, specifically Acropora palmata, react at a genetic level over time and across different reef sites is crucial for effective restoration.
  • The study found that the genetic identity of the coral had a more significant impact on growth and survival than the location or timing of outplanting, suggesting that considering genetic diversity could enhance coral restoration success, especially when planting in cooler months for better growth outcomes.

Bilateral adrenal hemorrhage (AH) is linked to various causes, including bacterial and viral infections, coagulopathies, and postoperative states. Symptoms can range from mild adrenal insufficiency to shock from Waterhouse-Friedrichsen syndrome. We present a case of a 47-year-old male with antiphospholipid antibody syndrome (APS) on warfarin who presented to the emergency department (ED) with bilateral flank pain and was found to have bilateral AH.

In this work, the cell line SW620-GFP has been used in a complete magnetic hyperthermia assay, from the preparation of the ferrofluid with folate-coated iron oxide nanoparticles to in vivo experiments. The physical and chemical characterization of the nanoparticles evidenced their superparamagnetic behaviour, an average diameter of 12 ± 4 nm, a 2 nm coat thickness, and a high-power loss density. The main innovation of the work is the exclusive capability of viable SW620-GFP cells to emit fluorescence, enabling fast analysis of both, cell viability in vitro with an epifluorescence microscope and tumour size and shape in vivo in a non-invasive manner using the iBox technology.
