The authors present data concerning influence of gas-masks with higher respiratory resistance on functional state of subjects performing physical and operator tasks. Finding are that only individuals with high general capacity for work (PWC170 over 3.0 W/kg of body weight) could perform tasks in heavy gas-masks, therefore only for them the specification of work and rest schedule is possible. Real flow rates for inspiration and expiration under physical load in gas-mask occurred exceeding the value (30 l/min) that is accepted in national standards and servers for calculating the individual respiratory protective means resistance to air flow.

When engaged in dynamic or continuous movements, action initiation involves modifying an ongoing motor program rather than initiating it from rest. Event-related theta synchronization over sensorimotor areas is a neurophysiological marker for modifying motor programs. We used electroencephalography (EEG) to examine how task complexity and age affect event-related synchronization (ERS) in the theta band during a dynamic bimanual, visuomotor pinch force task.

The path to survival for pathogenic organisms is not straightforward. Pathogens require a set of enzymes for tissue damage generation and to obtain nourishment, as well as a toolbox full of alternatives to bypass host defense mechanisms. Our group has shown that the parasitic protist encodes for 14 sphingomyelinases (SMases); one of them (acid sphingomyelinase 6, aSMase6) is involved in repairing membrane damage and exhibits hemolytic activity.

The work main purposes were to identify the sources of problems and demands causing parental burnout and to specify the resources/support factors during the COVID-19 pandemic. The study was based on the Balance Theory of Risk and Support/Resource Factors (BR Model) by Mikolajczak and Roskam. The study explored the predictive value of socio-economic variables, religiosity, the meaning of life, positivity, perceived social support, family functionality, and balance between risks and resources in parental burnout using the structural equation modelling method on a sample of 337 parents.

Phenolic compounds are an extensive group of natural and anthropogenic organic substances of the aromatic series containing one or more hydroxyl groups. The main sources of phenols entering the environment are waste from metallurgy and coke plants, enterprises of the leather, furniture, and pulp and paper industries, as well as wastewater from the production of phenol-formaldehyde resins, adhesives, plastics, and pesticides. Among this group of compounds, phenol is the most common environmental pollutant.

: The COVID-19 pandemic imposed immense stress on healthcare systems worldwide, significantly affecting the mental well-being of healthcare workers (HCWs). This study examined the sociodemographic, occupational, and COVID-19-related predictors of burnout syndrome among Serbian HCWs. : A cross-sectional survey of 400 doctors and nurses utilized the Maslach Burnout Inventory to assess emotional exhaustion, depersonalization, and personal accomplishment.
