Chemotherapeutic resistance: surviving stressful situations.

Exploring nursing staffs communication in stressful and non-stressful situations.

AIM To explore the factors that characterise the work environment, focusing on communication among nurses in stressful and non-stressful situations. BACKGROUND Nursing is often described as a stressful occupation. Implementation of change may be an additional stress factor. METHODS Nurses and assistant nurses completed a questionnaire from two different perspectives, 'communication in non-s...

Establishing the situated features associated with perceived stress.

We propose that the domain general process of categorization contributes to the perception of stress. When a situation contains features associated with stressful experiences, it is categorized as stressful. From the perspective of situated cognition, the features used to categorize experiences as stressful are the features typically true of stressful situations. To test this hypothesis, we ask...

The Relationship Between Patient Care Tolerance and Coping with Stressful Situations Among Nurses

Effects of corticosterone on innate and humoral immune functions and oxidative stress in barn owl nestlings.

The costs of coping with stressful situations are traded-off against other functions such as immune responses. This trade-off may explain why corticosterone secretion reduces immune reactions. Corticosterone differentially affects various immunity components. However, which component is suppressed varies between studies. It remains unclear whether the trade-off in energy, nutrition, autoimmunit...

DNA polymerase zeta regulates cisplatin cytotoxicity, mutagenicity, and the rate of development of cisplatin resistance.

DNA polymerase zeta participates in translesional bypass replication. Here we show that reduced expression of the catalytic subunit hREV3 renders human fibroblasts more sensitive to the cytotoxic effect of cisplatin, reduces their sensitivity to the ability of cisplatin exposure to generate drug resistant variants in the surviving population, and reduces the rate of emergence of resistance to c...
