Evaluation of Hypoxia Markers in Critically Ill Patients Categorized by Their Burden of Organ Dysfunction: A Novel Approach to Detect Pathophysiological and Clinical Relevance in a Secondary Analysis of a Prospective Observational Study.

In critically ill patients, compromised microcirculation causes tissue hypoxia, organ failure, and death. These pathophysiological processes occur particularly in patients with high illness severity, so reliable hypoxia biomarkers should reflect this in their occurrence. This secondary analysis of a prospective study categorized patients by their burden of organ dysfunction (BOD) using the cohort's median initial sequential organ failure assessment (SOFA) score of 8 as a cutoff.

Photo- and Cobalt-Catalyzed Cycloisomerization of Unsaturated Guanidines, (Iso-)Ureas, and Carbonates.

We report intramolecular photocatalyzed cycloisomerization of unactivated olefins with pendant nucleophiles. The reaction proceeds under mild conditions and utilizes guanidines, ureas, isoureas, isothioureas, and carbonates to yield several different five-, six-, and seven-membered heterocycles. Use of benzothiazinoquinoxaline as an organophotocatalyst and cobalt-salen catalyst obviates the need for a stoichiometric oxidant or reductant.

Protocol for isolating high-purity natural killer cells from peripheral blood of septic patients using magnetic cell separation.

In human sepsis, myelocytosis and concomitant lymphopenia complicate the study of peripheral blood natural killer (NK) cells. Here, we present a protocol for isolating NK cells from peripheral blood of septic patients using magnetic cell separation. We describe steps for the depletion of non-NK cells and NK cell enrichment.

Using eye tracking to assess learning of a multifunction prosthetic hand: an exploratory study from a rehabilitation perspective.

Background: Eye tracking technology not only reveals the acquisition of visual information at fixation but also has the potential to unveil underlying cognitive processes involved in learning to use a multifunction prosthetic hand. It also reveals gaze behaviours observed during standardized tasks and self-chosen tasks. The aim of the study was to explore the use of eye tracking to track learning progress of multifunction hands at two different time points in prosthetic rehabilitation.
