Physical influences on right ventricular infarction and cardiogenic shock in acute myocardial infarction.

Aim: To determine if complicated acute myocardial infarction (AMI) is related to specific cosmophysical activities.

Methods: The study group included 1170 patients who had undergone primary percutaneous coronary intervention (PCI) for AMI in 2000-2006. Geomagnetic and cosmic ray (neutron) activity (GMA, CRA) on the day of PCI were derived from international observatories.

The culprit artery in acute myocardial infarction in different environmental physical activity levels.

Background: The timing of acute coronary events may be related to endogenous and exogenous--environmental--factors.

Aim: To check if daily levels of geomagnetic activity (GMA) and/or cosmic ray activity (CRA) measured by neutron activity (imp/min) on the Earth's surface are related by timing with specific culprit artery of AMI.

Patients And Methods: Data of PCI for AMI (n=904, 696 men) from 01/2000 to 02/2006 (2251 days) were used for analysis.

Hyperactivity in rats following postnatal anoxia.

A model of hyperactive rats was produced by exposing pups to severe anoxia within 24 h following birth. These rats demonstrated augmented motor activity in ambulation, sniffing and rearing activities in an open field. Activity was significantly increased at 10 days of age, maximal at 20-25 days and returned to normal values around 6 weeks of age.
