New Insights into Health Conditions Related to Malfunctions in Clock Genes.

Chronotypes play a crucial role in regulating sleep-wake cycles and overall health. The aim of this study was to investigate chronotype, sleep quality, polymorphisms of clock genes and the level of leptin in serum. We used standardized questionnaires to assess chronotype and sleep quality.

Psychological Distress after the COVID-19 Pandemic among Anesthesiologists in Poland-An Observational Study.

Introduction: The response to the COVID-19 pandemic by anesthesiologists has been simply heroic. Unfortunately, there are very few evidence-based studies in the literature that focus on anesthesiologists' burnout during that time. The purpose of our study was to examine the psychological distress, after the COVID-19 pandemic, among anesthesiologists in Poland.

Micro- and Nanoparticulate Hydroxyapatite Powders as Fillers in Polyacrylate Bone Cement-A Comparative Study.

Acrylate polymer-based bone cements constitute the most popular bonding agents used in regenerative surgery. Due to their inferior biocompatibility, however, these materials are often enriched with ceramic additives including hydroxyapatite (HAp). The aim of this paper was to perform a comparative study of the acrylate cements filled with different content (3-21%) of nano- and microscale hydroxyapatite.
