Article Synopsis
- The study focuses on the crucian carp, a fish that survives in low-oxygen conditions and manages oxidative stress during re-oxygenation, making it a valuable model for understanding mitochondrial resilience.
- High-resolution respirometry was used to compare mitochondrial function and reactive oxygen species (ROS) production between crucian carp and mice at different temperatures (37°C and 8°C).
- Findings revealed significant differences in HO (hydrogen peroxide) production between species, suggesting that mitochondrial adaptations related to thermal sensitivity and complex efficiency could inform future advancements in transplant medicine.
Coinfection accelerates transmission to new hosts despite no effects on virulence and parasite growth.
Philos Trans R Soc Lond B Biol Sci
July 2024
One of the fundamental aims of ecological, epidemiological and evolutionary studies of host-parasite interactions is to unravel which factors affect parasite virulence. Theory predicts that virulence and transmission are correlated by a trade-off, as too much virulence is expected to hamper transmission owing to excessive host damage. Coinfections may affect each of these traits and/or their correlation.

Methods: The data stem from a prospective observational multicentre cross-sectional study and were collected through interviews and clinical examinations. The study involved 96 dentists from 76 hospital and private clinics and included 822 patients.
Background: To prevent anaphylaxis-associated illness, intramuscular epinephrine injection is recommended. Subcutaneous injection may reduce efficacy, and intraosseous injection promotes morbidity. A few studies suggested that commercially available thigh epinephrine autoinjectors (EAIs) may induce subcutaneous/intraosseous injection in some adults.
