A selected tomogram slices from 5 (A-E) serial tomograms to illustrate the number of micronemes (mic) and rhoptries in the conoid area.

open access: yes, 2022
All micronemes that were either partially or fully within the conoid were included. Conoid is highlighted with yellow arrowheads in all examples. Tomogram A illustrates the presence of 2 rhoptries and 5 micronemes within the conoid.

Cellular electron tomography of the apical complex in the apicomplexan parasite Eimeria tenella shows a highly organised gateway for regulated secretion.

open access: yesPLoS Pathogens, 2022
The apical complex of apicomplexan parasites is essential for host cell invasion and intracellular survival and as the site of regulated exocytosis from specialised secretory organelles called rhoptries and micronemes.

GEOMETRIC STUDY IN THE REALIZATION OF CONCRETE FURNITURE

open access: yesJournal of Industrial Design and Engineering Graphics, 2023
When we are looking to make a piece of furniture, indoor or outdoor, we immediately think that the requirements related to functionality, ergonomics, flexibility, aesthetics and design will be met. At the same time, through these pieces of furniture, we

Apicomplexans: A conoid ring unites them all.

open access: yesPLoS Biology, 2021
Apicomplexan parasites are defined by complex apical structures, which are necessary for interaction with incredibly diverse host cells. Two studies now amend a long-standing paradigm by showing conservation of an essential ring structure in the entire ...

Measurements in nm of conoid components, pre-conoidal rings and apical polar ring from Fig 1.

open access: yes, 2022
For 2 of the 14 tomograms (number 3 and number 12) the ends of a few of the conoid fibres extended past the imaging volume, for these conoids, only the fibres where the start and end were visible were included in the analysis of fibre length, spacing ...

Revisiting the Role of Toxoplasma gondii ERK7 in the Maintenance and Stability of the Apical Complex

open access: yesmBio, 2021
The conoid is an enigmatic, dynamic organelle positioned at the apical tip of the coccidian subgroup of the Apicomplexa, close to the apical polar ring (APR) from which the subpellicular microtubules (SPMTs) emerge and through which the secretory ...

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

open access: yesMolecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.
