Synchronisation of apical constriction and cell cycle progression is a conserved behaviour of pseudostratified neuroepithelia informed by their tissue geometry [PDF]
, 2022 Neuroepithelial cells balance tissue growth requirement with the morphogenetic imperative of closing the neural tube. They apically constrict to generate mechanical forces which elevate the neural folds, but are thought to apically dilate during mitosis.

Study of the structure of the apical construction in different conditions of the canal-root system
Эндодонтия Today, 2019 Despite the achievements of modern dentistry, the question of choosing the apical termination point of root canals for endodontic treatment remains opened. It is known, that the inflammatory processes of the tooth pulp do not make a destructive effect on

eLife, 2021 The Drosophila polarity protein Crumbs is essential for the establishment and growth of the apical domain in epithelial cells. The protein Yurt limits the ability of Crumbs to promote apical membrane growth, thereby defining proper apical/lateral ...

Avalanches depend on the magnitude of apical constriction in the MF.
, 2022 A: Time dependence of the cell number. The larger the apical constriction, the higher the cell number. B: Time dependence of the tissue area for different constriction strengths. The larger the apical constriction, the bigger the tissue area.

The apical submembrane cytoskeleton participates in the organization of the apical pole in epithelial cells [PDF]
, 1997 In a previous publication (Rodriguez, M.L., M. Brignoni, and P.J.I. Salas. 1994. J. Cell Sci. 107: 3145-3151), we described the existence of a terminal web-like structure in nonbrush border cells, which comprises a specifically apical cytokeratin ...

Apical constriction and invagination: A very self-reliant couple
Developmental Biology, 2010 Research from both laboratories is supported by grants from the Generalitat de Catalunya and grants from the Spanish Ministerio de Ciencia e Innovación and its Consolider-Ingenio 2010 Program.

eLife, 2022 Apical constriction driven by actin and non-muscle myosin II (actomyosin) provides a well-conserved mechanism to mediate epithelial folding. It remains unclear how contractile forces near the apical surface of a cell sheet drive out-of-the-plane bending ...

ACCURACY OF AUTO REVERSE FUNCTION IN INTEGRATED MOTOR COMPARED TO A STANDARD ELECTRONIC APEX LOCATOR IN DETERMINING THE WORKING LENGTH (IN VITRO STUDY) [PDF]
Alexandria Dental Journal, 2022 Introduction: Determination of working length and its control throughout root canal preparation remains challenging.Objectives: The purpose of this study was to evaluate accuracy of auto apical reverse (AAR) mode in an integrated motor and a standard ...

Rare Concurrence of Apical Hypertrophic Cardiomyopathy and Effusive Constrictive Pericarditis [PDF]
The Open Cardiovascular Medicine Journal, 2011 A 78-year-old man with a history of pulmonary tuberculosis was referred for preoperative evaluation of cardiac function. Echocardiography and cardiac cine magnetic resonance imaging (MRI) indicated apical hypertrophic cardiomyopathy (HCM), a thickened visceral pericardium, and a large pericardial effusion.
