The mechanisms involved during the desaturation process of a porous matrix
Traditionally, soil mechanics deals with soil in either of two states, saturated or dry. The effective stress concept proposed by Terzaghi has proven to be valid for soils in either of these states. However, when the water or air phase becomes large enough, the soil no longer behaves as two-phase …

Hypoxaemia during tracheal intubation in patients with hypertensive disorders of pregnancy: analysis of data from an obstetric airway management registry
… disorders of pregnancy are associated with desaturation during tracheal intubation. Methods Data from 402 cases in a multicentre obstetric airway management registry were analysed. The prevalence of peri-induction hypoxaemia (SpO2<90%) was compared in patients with and without hypertensive …

Isoflurane : interaction with hepatic microsomal enzymes
… not inhibit the Δ9-desaturase and inhibited Δ6-desaturation of linoleic acid, but not the Δ6-desaturation of α-linolenic acid. The inhibition of the Δ6-desaturation of linoleic acid occurred at low millimolar concentrations of isoflurane. lsoflurane inhibits the Δ5-desaturation of eicosa-8, 11, …

The relative roles of portal hypertension and of cirrhosis in the pathogenesis of pulmonary lesions associated with chronic liver disease
… associated low TLCOsb and one developed arterial desaturation on exercise. A similar pattern was seen in three patients with cirrhosis. All had low TLCOsb and one developed arterial desaturation during exercise. In the cirrhotic group however three additional patients showed reduction in Pa02 …

Predictors of difficult intubation in obstetric cohort of patients: an analysis of the prospective obstetric airway management registry (OBAMR) (substudy – R025/2018)
… The primary outcome was defined as arterial desaturation to < 90% during obstetric airway management. For this purpose, multivariable binary logistic regression was performed. Hypoxaemia was thus used as a composite indicator of anatomical and physiological difficulty. Results: Data was …

The Role of Fasting Acylcarnitines in Metabolic Flexibility from Short Term High Fat Feeding
… glucose oxidation (P=0.0295), C16:1/C16:0 desaturation index (P= 0.0397), and C18:1/C18:0 desaturation index (P=0.0012). We did not find that individual changes in flexibility correlated with circulating acylcarnitine measurements in a fasted state

Understanding the biochemical basis of temperature induced lipid pathway adjustments in plants
… lipids include alterations in fatty acid desaturation, proportional changes in membrane lipids as well as molecular composition of each lipid species. In this study, I systematically explored the significance of glycerolipid pathway balance in temperature induced lipid composition changes …

THE ROLE OF BOTANICAL OILS ENRICHED IN FADS2-DERIVED N-3 VS. N-6 POLYUNSATURATED FATTY ACIDS IN PREVENTION OF ATHEROSCLEROSIS
… (FADS2, delta-6 desaturase) step of fatty acid desaturation and elongation results in 18 and ≥ 20 carbon PUFAs that are substrates for pro-inflammatory and anti-inflammatory eicosanoid production, which affect atherosclerosis progression and inflammation. We previously showed that an atherogenic …

Regulation of n-3 PUFA biosynthesis in proliferating and differentiated PC12 pheochromocytoma cells
… glycerophospholipids (GPL) via the elongation/desaturation pathway following alpha-linolenic acid (ALA, 18:3n-3) supplements was observed.That was accompanied by a marked reduction of eicosatrienoic acid (Mead acid, 20:3n-9), an index of PUFA deficiency. EPA supplements were similarly converted …

A novel approach to real-time monitoring of erythrocyte ATP release as a function of hypoxia
… consistent with the range of PO2 that elicits Hb desaturation in RBCs. This approach may allow for detailed mechanistic studies into the relationship between hypoxia, Hb desaturation, and RBC ATP release.
