Downregulation of O‐GlcNAcylation enhances etoposide‐induced p53‐mediated apoptosis in HepG2 human liver cancer cells

open access: yesFEBS Open Bio, EarlyView.
Etoposide, a topoisomerase II inhibitor, reduces O‐GlcNAcylation in HepG2 liver cancer cells. Further inhibition of O‐GlcNAc transferase by OSMI‐1 enhanced etoposide‐induced apoptosis, lowering the IC50 for viability and increasing the EC50 for cytotoxicity.

Atrial fibrillation and electrophysiology in transgenic mice with cardiac-restricted overexpression of FKBP12 [PDF]

open access: yes, 2019
Cardiomyocyte-restricted overexpression of FK506-binding protein 12 transgenic (αMyHC-FKBP12) mice develop spontaneous atrial fibrillation (AF). The aim of the present study is to explore the mechanisms underlying the occurrence of AF in αMyHC-FKBP12 ...

A case of complete heart block with a therapeutic dilemma [PDF]

open access: yes, 2020
Third-degree atrioventricular (AV) block, also referred to as complete heart block (CHB), is caused by a cardiac conduction system disease or damage resulting in no conduction through the atrioventricular node (AVN), leading to complete dissociation of ...

Cardiac arrhythmias and conduction defects in systemic sclerosis [PDF]

open access: yesRheumatology, 2013
Signs and symptoms of arrhythmias or conduction defects are frequently reported in patients with SSc. These rhythm disorders may have several origins (i.e., related to primary heart involvement, pericardial disease, valvular regurgitation or pulmonary arterial hypertension) and may negatively affect the overall prognosis of these patients.

Origin and the embryonic transformations of vertebrate heart conducting system. [PDF]

open access: yesМорфологія, 2007
As the embryonic structure, the cardiac conduction system must continue to develop in a coordinated manner at all embryonic stages. This requires not only the formation of distinct components of the conduction system, but the integration of these ...

Value of multi-detector computed tomography in delineation of the normal cardiac conduction system and related anatomic structures

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2016
The cardiac conduction system is responsible for rhythmic myocardial stimulation for physiologic contraction of the heart. Aim of the work: To assess the value of MDCT in outlining anatomic landmarks and variants of conductive system, therefore provides ...

Digital Investigation of Security Attacks on Cardiac Implantable Medical Devices [PDF]

open access: yesEPTCS 165, 2014, pp. 15-30, 2014
A Cardiac Implantable Medical device (IMD) is a device, which is surgically implanted into a patient's body, and wirelessly configured using an external programmer by prescribing physicians and doctors. A set of lethal attacks targeting these devices can be conducted due to the use of vulnerable wireless communication and security protocols, and the ...
