Circadian rhythms and circadian clock gene homologs of complex alga Chromera velia

open access: yesFrontiers in Plant Science, 2023
Most organisms on Earth are affected by periodic changes in their environment. The circadian clock is an endogenous device that synchronizes behavior, physiology, or biochemical processes to an approximately 24-hour cycle, allowing organisms to ...

Case report: Sarcocystis speeri, Aspergillus fumigatus, and novel Treponema sp. infections in an adult Atlantic spotted dolphin (Stenella frontalis)

open access: yesFrontiers in Veterinary Science, 2023
A complete postmortem examination, including a computed tomography scan “virtopsy” (virtual necropsy), gross necropsy, cytology, histology, and molecular diagnostics were performed to investigate the cause of death of a deceased adult male Atlantic ...

Colpodella sp. (ATCC 50594) Life Cycle: Myzocytosis and Possible Links to the Origin of Intracellular Parasitism

open access: yesTropical Medicine and Infectious Disease, 2021
Colpodella species are free living bi-flagellated protists that prey on algae and bodonids in a process known as myzocytosis. Colpodella species are phylogenetically related to Apicomplexa. We investigated the life cycle of Colpodella sp. (ATCC 50594) to

Essential function of the alveolin network in the subpellicular microtubules and conoid assembly in Toxoplasma gondii

open access: yeseLife, 2020
The coccidian subgroup of Apicomplexa possesses an apical complex harboring a conoid, made of unique tubulin polymer fibers. This enigmatic organelle extrudes in extracellular invasive parasites and is associated to the apical polar ring (APR).

ATP, an extracellular signaling molecule in red blood cells: A messenger for malaria?

open access: yesBiomedical Journal, 2014
Adenosine 5′ triphosphate (ATP), discovered in 1929 by Karl Lohmannest, is described as an essential energy source for cells. In the biochemistry of all living organisms, ATP hydrolysis provides the energy required for the chemical reactions of ...
