Transnitrosation Signals Oxyhemoglobin Desaturation [PDF]

Circulation Research, 2008
See related article, pages 545–553 Erythrocytes dilate peripheral blood vessels as a function of oxyhemoglobin desaturation.1 This effect increases regional blood flow to hypoxic tissues. The mechanisms underlying the peripheral vasodilatory effects of desaturating erythrocytes are incompletely understood but do not involve activation of local ...

Polyunsaturated fatty acid accumulation in the lipids of cultured fibroblasts and smooth muscle cells

Journal of Lipid Research, 1981
The lipid content per cell of cells in tissue culture depended on the cell type. Fibroblasts derived from human neonatal foreskin contained less triglyceride and phospholipid and more cholesteryl ester than smooth muscle cells derived from guinea pig ...

Arterial desaturation dependent on posture [PDF]

Thorax, 1969
A 60-year-old woman developed subacute bacterial endocarditis following a minor operation. She presented the unusual picture of breathlessness with cyanosis related to posture, confirmed by laboratory measurement. She had an atrial septal defect with right-to-left shunt, and had sustained multiple pulmonary infarcts, resulting in the obliteration of a ...

Electrochemically driven desaturation of carbonyl compounds [PDF]

Nature Chemistry, 2020
Electrochemical techniques have long been heralded for their innate sustainability as efficient methods for achieving redox reactions. Carbonyl desaturation, as a fundamental organic oxidation, is an oft-employed transformation to unlock adjacent reactivity. To date, the most reliable methods for achieving it have relied on transition metals (Pd/Cu)

Second‐Sphere Aromatic Substitutions That Tune H‐Atom Transfer Reactivity Observed for a Series of S = 1 Nonheme FeIV=O Complexes: An Enthalpy‐Entropy Compensation Effect

Angewandte Chemie, EarlyView.
A series of oxoiron(IV) complexes was synthesized to determine the impact of electronically tuned aromatic substitution in the secondary sphere of the ligand. Despite possessing identical electronic properties, they show significant differences in C─H oxidation reactions.

Direct Access to Chiral Piperidines by Enantioselective HAT‐Initiated C(sp3)─H Oxidation

Angewandte Chemie, EarlyView.
The direct desymmetrization of piperidines is achieved through manganese‐catalyzed enantioselective α‐C(sp3)─H oxidation with hydrogen peroxide, affording versatile chiral N,O‐acetals in good yields and with high enantio‐ and diastereoselectivity. These intermediates provide access to diverse functionalized piperidines with retention of chirality ...

Age and clinical signs as predictors of COVID-19 symptoms and cycle threshold value

Libyan Journal of Medicine, 2022
Many COVID-19 infected people remain asymptomatic, and hence the diagnosis at first presentation remains a challenge. Assessment at a presentation in primary care settings is usually done by visual triaging and basic clinical examination.

Oxygen Desaturation during Endoscopy in the Elderly [PDF]

Journal of the Royal College of Physicians of London, 1993
Arterial oxygen desaturation during oesophago-gastro duodenoscopy (OGD) is well recognised. It has been suggested that severe desaturation (greater than 7%) may predispose patients with cardiopulmonary disease and the elderly to cardiac arrhythmias. During OGD, of 106 elderly patients 26 developed ventricular and/or supraventricular ectopics, but these
