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.

Effect of CO₂ Partial Pressure on the Corrosion Behavior of S135 Steel in CO₂/H₂S Coexistence Systems [PDF]

Cailiao Baohu
In order to clarify the influence and regularity of CO2 partial pressure on the corrosion behavior of S135 steel in the CO2/H2S coexistence system， the corrosion simulation test of S135 steel in CO2/H2S coexistence systems was conducted by using ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

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.

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 ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

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.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
