Currently there are few antibacterial dosage regimens established to be safe and effective for sea turtles. Pharmacokinetic evaluation of antibiotics is an essential step in establishing accurate dosage guidelines for a particular species. Metronidazole is an antibiotic that is effective against anaerobic bacteria and some protozoa.

The Hunga Tonga-Hunga/Hunga-Ha'apai eruption on January 15, 2022 sent off a plume of ash material up to the stratosphere and triggered a meteotsunami and barometric pressure pulse that rippled through the atmosphere and oceans all around the world. The nature of the volcanic event and its global impacts on the oceans, atmosphere, lithosphere and the cryosphere are a matter of debate. Here we present a first overview of the time travel of the sound atmospheric pressure wave through the Antarctic continent based on in situ measurements, which represented a unique event observed through the polar ice sheet during the instrumental meteorological era.

Article Synopsis
  • The study investigates how antiviral monoclonal antibodies (mAbs), particularly casirivimab and imdevimab (CAS+IMD), affect immune responses when individuals are vaccinated against SARS-CoV-2 after receiving mAb treatment.
  • It was found that the presence of CAS+IMD during vaccination reduced the effectiveness of the vaccine in generating neutralizing antibodies, though other immune responses remained intact.
  • This reduction in antibody production is linked to "epitope masking," but can be reversed with booster shots, and influences the immune response differently in those who had not yet begun their natural immunity when treated with mAbs.
