متن کاملWarm up and cool down!
In adaption to shifts in ambient temperature, both prokaryotic and eukaryotic cells maintain physiological homeostasis by adjusting various cellular properties, including membrane lipid fluidity, the capacity to maintain proteostasis and rate of protein synthesis [1]. How cells respond to temperature changes is a fundamental question in cell physiology. Here we briefly review current understand...

Most singers prefer to warm up their voices before performing. Although the subjective effect is often considerable, the underlying physiological effects are largely unknown.

For example treadmill exercise testing does not allow rest and imposes incremental increase...
