Work anxiety factors, coronavirus anxiety and job satisfaction of Polish nurses facing COVID-19 pandemic outbreak.

Background: During the SARS-CoV-2 pandemic, as in past disasters and emergencies, nurses around the world play an important role. What is more, the unprecedented pressure exerted by the pandemic on healthcare systems in every country brings big challenges to nurses, which may affect their well-being, work efficacy and job satisfaction.

Objective: The main objective of the presented studies was to describe anxiety factors related to the work of nurses during the SARS-CoV-2 pandemic; to assess the intensity of coronavirus anxiety and job satisfaction experienced by nurses at that time; to assess predictors of job satisfaction of nurses during the COVID-19 pandemic; to assess the differences in the intensity of job satisfaction and coronavirus anxiety depending on the selected variables related to their experiences during the COVID-19 pandemic.

Specificities of Gβγ subunits for the SNARE complex before and after stimulation of α-adrenergic receptors.

Ligand binding to G protein–coupled receptors (GPCRs), such as the α-adrenergic receptor (αAR), results in the activation of heterotrimeric G proteins, which consist of functionally distinct Gα subunits and Gβγ dimers. αAR-dependent inhibition of synaptic transmission regulates functions such as spontaneous locomotor activity, anesthetic sparing, and working memory enhancement and requires the soluble attachment protein receptor (SNARE) complex, a Gβγ effector. To understand how the Gβγ-SNARE complex underlies the αAR-dependent inhibition of synaptic transmission, we examined the specificity of Gβγ subunits for the SNARE complex in adrenergic neurons, in which auto-αARs respond to epinephrine released from these neurons, and nonadrenergic neurons, in which hetero-αARs respond to epinephrine released from other neurons.

Sense of coherence and strategies for coping with stress among nurses.

Background: The nursing profession is associated with constant presence of difficult situations and stress, which arise from responsibility for the highest values - human life and health. With demographic changes in the society, the demand for nursing care increases. Looking after the health of nursing staff becomes a non-material investment in employees.

Nurses' sense of coherence and stress management strategies against the types of health status.

Aim: The main objective of this paper was to establish types of health status in the group of practicing nurses.

Design: Positive psychology defines human health as the underlying resource for all life activities, including professional work. Practicing nurses are exposed to a variety of professional pressures, most notably high-stress burden.

Noise of underwater explosions in the North Sea. A comparison of experimental data and model predictions.

An analysis is presented of sound measurements performed near two detonations of unexploded ordnance (UXO) in the North Sea, at distances ranging from 1.5 to 12 km. The charge masses of the detonations were 325 and 140 kg TNT equivalent.
