This article presents a comparison of the test results of selected mechanical parameters (hardness, Young's modulus, critical force for delamination) for protective filters intended for eye protection against harmful infrared radiation. Filters with reflective metallic films were studied, as well as interference filters developed at the Central Institute for Labour Protection - National Research Institute (CIOP-PIB). The test results of the selected mechanical parameters were compared with the test results, conducted in accordance with a standardised method, of simulating filter surface destruction that occurs during use.

Human sweat has the potential to be sufficiently utilized for noninvasive monitoring. Given the complexity of sweat secretion, the sensitivity and selectivity of sweat monitoring should be further improved. Here, we developed an olfactory-inspired separation-sensing nanochannel-based electronic for sensitive and selective sweat monitoring, which was simultaneously endowed with interferent separation and target detection performances.

Purpose Of Review: The increasing use of prone position, in intubated patients with acute respiratory distress syndrome as well as in patients with acute hypoxemic respiratory failure receiving noninvasive respiratory support, mandates a better definition and monitoring of the response to the manoeuvre. This review will first discuss the definition of the response to prone positioning, which is still largely based on its effect on oxygenation. We will then address monitoring respiratory and hemodynamic responses to prone positioning in intubated patients.

Background: Invasive procedures and environmental factors in the intensive care unit (ICU) may cause anxiety and discomfort in patients, who often require sedation therapy. The aim of this study was to assess the safety of remimazolam tosilate for procedural sedation in ICU patients receiving mechanical ventilation following endotracheal intubation. Eighty patients from a single centre were randomly assigned to either the propofol group or the remimazolam group.

AC is significantly influenced by arterial wall structure and vasomotion, and it markedly influences cardiac load. A new method, based on a two-element Windkessel model, has been recently proposed for estimating AC as the ratio of the time constant T of the diastolic blood pressure decay and peripheral vascular resistance derived from clinically available stroke volume measurements and selected peripheral blood pressure parameters which are less prone to peripheral distortions.

Backgroud: Intervertebral disc degeneration (IDD) is one of the common degenerative diseases. Due to ethical constraints, it is difficult to obtain sufficient research on humans, so the use of an animal model of IDD is very important to clarify the pathogenesis and treatment mechanism of the disease.
Methods: In this study, thirty 2-month-old mice were selected for operation to establish a coccygeal IDD model.
