Survey of ST-Segment Changes due to Active Lead Fixation during Permanent Pacemaker Device Implantation as a Prognostic Indicator of its Performance

مجله دانشکده پزشکی اصفهان, 2017
Background: Active lead implantation can create injury in myocardium that may be associated with a ST-segment elevation. This ST-segment elevation may be correlated with changes in other parameters such as threshold, sense, amplitude, impedance, and ...

Post-Implant Global Longitudinal Strain as a Predictor of Pacing-Induced Cardiomyopathy in Patients with Preserved Ejection Fraction Undergoing Pacemaker Placement

Reviews in Cardiovascular Medicine
Background: Right ventricular (RV) pacing exacerbates heart failure and increases cardiac mortality in patients with reduced ejection fraction (EF).

Effective faking of verbal deception detection with target‐aligned adversarial attacks

Legal and Criminological Psychology, EarlyView.
Abstract Background Deception detection through analysing language is a promising avenue using both human judgements and automated machine learning judgements. For both forms of credibility assessment, automated adversarial attacks that rewrite deceptive statements to appear truthful pose a serious threat.

Effect of artificial gravity on calcaneal bone marrow adipose tissue and mineral content in female and male participants in 60 days of bed rest

Experimental Physiology, EarlyView.
Abstract Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt bed rest.

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

Experimental Physiology, EarlyView.
Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Fmr1 knockout disrupts multiple intrinsic properties via reduced HCN channel activity in mediodorsal thalamocortical neurons

Experimental Physiology, EarlyView.
Abstract The neurodevelopmental disorder fragile X syndrome (FXS) results from hypermethylation of the FMR1 gene, which prevents production of the FMRP protein. FMRP modulates the expression and function of a variety of proteins, including voltage‐gated ion channels, such as hyperpolarization‐activated and cyclic nucleotide‐gated (HCN) channels, which ...
