Infrared thermography: principles and applications

All objects with surface temperatures above absolute zero emit electromagnetic radiation. In this paper we describe the physical principles that allow calculation of the surface temperatures of objects from the wavelength and intensity of electromagnetic radiation emitted in the infrared region of the spectrum (infrared thermography). This technique can be applied to measure the surface […]

Chronic melatonin administration mitigates behavioral dysfunction induced by γ-irradiation

Melatonin, a ‘hormone of darkness,’ has been reported to play a role in a wide variety of physiological responses including reproduction, circadian homeostasis, sleep, retinal neuromodulation, and vasomotor responses. Our recent studies reported a prophylactic effect of exogenous melatonin against radiation-induced neurocognitive changes. However, there is no reported evidence for a mitigating effect of chronic […]
