An unwanted effect of antibiotic treatment is promotion of antibiotic resistance through the dissemination of resistance genes and the selection of resistant subpopulations of bacteria. Prudhomme et al. discovered that the stress of exposure to antibiotics triggers competence ("parasexuality") in ...

Stress, Mutators, Mutations and Stress Resistance
2009Organisms need genetic mechanisms to rapidly adapt to changing, stressful environments. Having a high mutation frequency would have a drag on a population due to the deleterious nature of mutations, but having a sub-population with high mutation rate due to the presence of mutator genes seems to be nature’s solution.

The psychological syndrome of burnout is of key importance to nurse managers, given that it is a widespread problem, with anywhere from 10–78% of European and American nurses considering themselves to be “burned out.” Reviewing the literature on the consequences of burnout for individual nurses, patients, teams, and healthcare organizations, it is ...

Insulin Resistance of Stress: Sites and Mechanisms
Clinical Science, 19931. Stress is associated with a severe, yet reversible, form of insulin resistance. The aim of this study was to quantify the kinetics of insulin action (sensitivity and responsiveness) on intermediary metabolism during post-surgical stress. 2.

ABSTRACT A collection of notcs on the stresses set up in glassware of various sorts by various forces and treatments is presented, with some observations on how the stresses act to produce failure.

Abstract Resistance to environmental stress may involve mechanisms that are highly specific for one type of stress, such as detoxification pathways restricted to a particular class of insecticide, or may cover different stresses, and have a common physiological/biochemical basis. We have already encountered a general resistance mechanism

Autonomic responsiveness in stress‐sensitive and stress‐resistant pigs
Journal of Veterinary Pharmacology and Therapeutics, 1981The responsiveness of the autonomic nervous system was studied in twenty‐six 140 day old thiopentone anaesthetized lean stress‐sensitive Pietrain (P) and fatter stress‐resistant Gloucester (G) pigs, using the Valsalva like manoeuvre (VLM), and the i.v. tyramine, noradrenaline (NA) and phenylephrine tests.

Resistance to abiotic stresses
1993World food production is limited primarily by environmental stresses. It is very difficult to find ‘stress free’ areas where crops may approach their potential yields. Abiotic environmental factors are considered to be the main source (71%) of yield reductions (Boyer, 1982).

Abrasion resistance of pre‐stressed and stressed rubber vulcanizates
Journal of Applied Polymer Science, 1970AbstractThe abrasion resistance of carbon black‐reinforced SBR‐1500 vulcanizates has been shown to be drastically reduced by the application of tensile strain during the abrasion process. Pre‐stressing of similar vulcanizates, however, has no effect upon the abrasion resistance.

Sucrose transporters of resistant grapevine are involved in stress resistance
Plant Molecular Biology, 2019The whole promoter regions of SUTs in Vitis were firstly isolated. SUTs are involved in the adaptation to biotic and abiotic stresses. The vulnerability of Vitis vinifera to abiotic and biotic stresses limits its yields. In contrast, Vitis amurensis displays resistance to environmental stresses, such as microbial pathogens, low temperatures, and ...
