Loss of heat‐shock acquisition of thermotolerance in yeast is not correlated with loss of heat‐shock proteins [PDF]

open access: yesFEBS Letters, 1986
Yeast cells when subjected to a primary heat shock, defined as a temperature shift from 23 to 37° for 30 min, acquired tolerance to heat stress (52°C/5 min). Primary heat shocked cells incubated at 23°C for up to 3 h, progressively lost thermotolerance but retained high levels of the major heat‐shock proteins as observed on polyacrylamide gels.

Heat loss prevention in neonates [PDF]

open access: yesJournal of Perinatology, 2008
Maintaining a neutral thermal environment is one of the key physiologic challenges a newborn infant faces after delivery. Attention to detail regarding the management of an infant's neutral thermal environment may lead to improvement in clinical outcome, including improved survival. The details of this management cover a broad spectrum of interventions,
