Modeling conoid surfaces [PDF]

Facta Universitatis. Series: Architecture and Civil Engineering, 2002
In tins paper we consider conoid surfaces as frequently used surfaces in building techniques, mainly as daring roof structures. Different types of conoids are presented using the programme package Mathematica. We describe the generation of conoids and by

Molecular characterization of the conoid complex in Toxoplasma reveals its conservation in all apicomplexans, including Plasmodium species

PLoS Biology, 2021
The apical complex is the instrument of invasion used by apicomplexan parasites, and the conoid is a conspicuous feature of this apparatus found throughout this phylum.

An apical ring protein essential for conoid complex assembly and daughter cell formation in Toxoplasma gondii [PDF]

Nature Communications
In Toxoplasma gondii, the conoid complex consists of intraconoidal microtubules (ICMTs), preconoidal rings (PCRs), apical polar ring (APR), and the conoid.

RNG2 tethers the conoid to the apical polar ring in Toxoplasma gondii to enable parasite motility and invasion. [PDF]

PLoS Biology
The conoid is a dynamic, tubulin-based structure conserved across the Apicomplexa that undergoes extrusion during egress, gliding motility, and invasion in Toxoplasma gondii.

A conserved ankyrin repeat-containing protein regulates conoid stability, motility and cell invasion in Toxoplasma gondii

Nature Communications, 2017
Apicomplexan parasites such as Toxoplasma gondii possess a tubulin-rich structure called the conoid. Here, Long et al. identify a conoid protein that interacts with motor and structural proteins and is required for structural integrity of the conoid ...

Risk factors for coracoclavicular reconstruction failure: a systematic review [PDF]

JSES International
Background: The coracoclavicular (CC) ligament reconstruction for acromioclavicular injuries is performed through a variety of surgical techniques and fixation methods. The purpose of this study is to determine the risk factors associated with failure of

Expansion microscopy provides new insights into the cytoskeleton of malaria parasites including the conservation of a conoid

PLoS Biology, 2021
Malaria is caused by unicellular Plasmodium parasites. Plasmodium relies on diverse microtubule cytoskeletal structures for its reproduction, multiplication, and dissemination.

Effect of deltoid–trapezius overlap repair on acromioclavicular joint stability: a biomechanical study using fresh-frozen cadavers [PDF]

BMC Musculoskeletal Disorders
Background Severe acromioclavicular (AC) joint dislocation is associated with damage to the deltoid and trapezius muscles. However, studies on the role of these muscles in AC joint stability are limited.

Apicomplexans: A conoid ring unites them all.

PLoS 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 ...
