The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Imputation of arterial oxygen partial pressures using pulse oximetry in surgical patients under general anaesthesia: A prospective cohort study

Indian Journal of Anaesthesia
Background and Aims: Monitoring oxygen saturation (SpO2) during general anaesthesia using pulse oximetry is mandatory, though it may not always reflect the actual oxygenation status.

Development of a Patch-Type Flexible Oxygen Partial Pressure Sensor

IEEE Journal of Translational Engineering in Health and Medicine, 2020
Oxygen concentration in living organisms is one of the important vital indicators in emergency care and bedside medical settings. However, the oximetry method has limitations: the measurement site is limited to the tissue containing blood and the ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Effects of Oxygen Partial Pressure on 4-Hydroxy-2-Nonenal Induced Oxymyoglobin Oxidation

Meat and Muscle Biology, 2019
4-hydroxyl-2-nonenal (HNE) is a lipid oxidation product that can increase oxymyoglobin oxidation. However, limited research has evaluated the role of oxygen partial pressure in HNE-induced metmyoglobin formation.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Correlação entre as pressões parciais de co2 no ar expirado e no sangue arterial, em porcas submetidas a pneumoperitônio

Revista do Colégio Brasileiro de Cirurgiões
OBJETIVO: As cirurgias realizadas por via laparoscópica, que utilizam CO2 para realização do pneumoperitônio, cursam com hipercarbia. Esta alteração pode ser estimada pela pressão parcial de CO2 no ar expirado.
