Annexin A4 and A6 induce membrane curvature and constriction during cell membrane repair

open access: yesNature Communications, 2017
Efficient cell membrane repair mechanisms are essential for maintaining membrane integrity and thus for cell life. Here we show that the Ca2+- and phospholipid-binding proteins annexin A4 and A6 are involved in plasma membrane repair and needed for rapid

The Heterogeneous Expressions of Pericardial Disease: A Case Report/Series [PDF]

open access: yesReviews in Clinical Medicine, 2019
Introduction: The pericardium may have various phenotypic manifestations in assorted disease states, such as acute pericarditis, effusive constrictive pericarditis, and constrictive pericarditis.

May-Thurner Syndrome, an Often Overlooked Cause of Deep Vein Thrombosis: A Case Report

open access: yesOman Medical Journal, 2021
Deep vein thrombosis (DVT) is a common medical condition, but the predisposing anatomical factors, which may be amenable to definitive treatment, are usually overlooked. Therefore, a high index of clinical suspicion is the key to early diagnosis.

Constriction of the mitochondrial inner compartment is a priming event for mitochondrial division

open access: yesNature Communications, 2017
Mitochondrial division is critical for the maintenance and regulation of mitochondrial function, quality and distribution. This process is controlled by cytosolic actin-based constriction machinery and dynamin-related protein 1 (Drp1) on mitochondrial ...

Aortic Stiffness Hysteresis in Isolated Mouse Aortic Segments Is Intensified by Contractile Stimuli, Attenuated by Age, and Reversed by Elastin Degradation

open access: yesFrontiers in Physiology, 2021
Aim: Cyclic stretch of vascular tissue at any given pressure reveals greater dimensions during unloading than during loading, which determines the cardiac beat-by-beat hysteresis loop on the pressure-diameter/volume relationship.

Bacterial outer membrane constriction

open access: yesMolecular Microbiology, 2018
The outer membrane of Gram‐negative bacteria is a crucial permeability barrier allowing the cells to survive a myriad of toxic compounds, including many antibiotics.

Pericardial Constriction with Severe Mitral Regurgitation: An Uncommon Association

open access: yesJournal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2020
Pericardial constriction is a condition, in which there is a lack of transmission of changes in intrathoracic pressures to the structures encased in pericardium due to thickened, fibrosed, and most of the cases, calcified pericardium.

A positive-feedback-based mechanism for constriction rate acceleration during cytokinesis in Caenorhabditis elegans

open access: yeseLife, 2018
To ensure timely cytokinesis, the equatorial actomyosin contractile ring constricts at a relatively constant rate despite its progressively decreasing size. Thus, the per-unit-length constriction rate increases as ring perimeter decreases.

Time-dependent and force-dependent vasoreactivity of isolated human umbilical arteries [PDF]

open access: yesScripta Medica, 2020
Background/Aim: There have been different experimental conditions for in vitro studies on human umbilical arteries (HUA) in tissue bath system. This diversity was mainly reflected in variables such as stretching tension, incubation period and initial ...

Turgor Pressure and Possible Constriction Mechanisms in Bacterial Division

open access: yesFrontiers in Microbiology, 2018
Bacterial cytokinesis begins with the assembly of FtsZ into a Z ring at the center of the cell. The Z-ring constriction in Gram-negative bacteria may occur in an environment where the periplasm and the cytoplasm are isoosmotic, but in Gram-positive ...
