DNA coiled coils [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
We report the coiled-coil structure of DNA, which is generated by the dodecanucleotide d(ATATATATATAT). The structure has been determined by single-crystal x-ray crystallography. The molecules form duplexes with single-stranded overhangs, which associate with neighbor molecules and give rise to infinite double helices in a coiled-coil conformation ...

ARCIMBOLDOon coiled coils [PDF]

open access: yesActa Crystallographica Section D Structural Biology, 2018
ARCIMBOLDOsolves the phase problem by combining the location of small model fragments usingPhaserwith density modification and autotracing usingSHELXE. Mainly helical structures constitute favourable cases, which can be solved using polyalanine helical fragments as search models. Nevertheless, the solution of coiled-coil structures is often complicated

Endovascular Management of Cerebral Aneurysms of the Posterior Cerebral Artery

open access: yesFrontiers in Neurology, 2021
Purpose: To investigate the safety and efficacy of endovascular embolization of cerebral aneurysms at the P1–P3 segments of the posterior cerebral artery (PCA).Materials and Methods: Seventy-seven patients with 77 PCA aneurysms who were treated with ...

Rapid temporary coiling of the parent artery for the management of intraprocedural aneurysm rupture

open access: yesBrain Circulation, 2020
Intraprocedural rupture (IPR) of an intracranial aneurysm is the most feared complication of primary and stent-assisted coiling because it carries a high risk of morbidity and mortality.

Endovascular Management of Iatrogenic Pseudoaneurysm of Internal Maxillary Artery after Dental Extraction

open access: yesJournal of Clinical Interventional Radiology ISVIR, 2022
Pseudoaneurysm developing from the internal maxillary artery is a rare but potentially fatal condition. We describe a case of iatrogenic pseudoaneurysm of the internal maxillary artery developed during dental extraction and successful endovascular ...

The coiled coil‐helix‐coiled coil‐helix proteins may be redox proteins [PDF]

open access: yesFEBS Letters, 2009
A number of nuclear encoded proteins are imported in to the intermembrane space of mitochondria where they adopt a coiled coil‐helix‐coiled coil‐helix (CHCH) fold. Two disulfide bonds formed by twin CX3C or CX9C motifs stabilize this fold. Some of these proteins are also characterized at their N‐termini by the presence of two additional cysteine ...

A seven-helix coiled coil [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
Coiled-coil proteins contain a characteristic seven-residue sequence repeat whose positions are designated a to g. The interacting surface between α-helices in a classical coiled coil is formed by interspersing nonpolar side chains at the a and d positions with hydrophilic residues at the flanking e and g positions.

Evolutionary Patterns in Coiled-Coils [PDF]

open access: yesGenome Biology and Evolution, 2015
Models of protein evolution are used to describe evolutionary processes, for phylogenetic analyses and homology detection. Widely used general models of protein evolution are biased toward globular domains and lack resolution to describe evolutionary processes for other protein types.

Initial experience with aneurysm coiling in Nepal

open access: yesNepal Journal of Neuroscience, 2018
The aim of this study is to show the result of aneurysm coiling despite the difficulty in initiating neurointervention in Nepal. It is a retrospective study where only aneurysm that has undergone coiling are taken from 2017 to 2018.A total of eleven ...

The evolution of antennal courtship in diplazontine parasitoid wasps (Hymenoptera, Ichneumonidae, Diplazontinae)

open access: yesBMC Evolutionary Biology, 2010
Background As predicted by theory, traits associated with reproduction often evolve at a comparatively high speed. This is especially the case for courtship behaviour which plays a central role in reproductive isolation.
