Chlorine‐Free Synthesis of P‐Esters: Microwave‐Assisted Direct Esterification of Phosphinic, Phosphonic, as Well as Phosphoric Acid Derivatives

Chemistry–Methods, Volume 6, Issue 7, July 2026.
The esterification of phosphinic, phosphonic, and phosphoric acids is not possible due the high enthalpy of activation. However, the barrier may be overcome under MW irradiation to give phosphinates, phosphonates, and alkoxyphosphoric acids, respectively. In the latter cases, the remaining P(O)OH group was esterified by alkylation.

The relationships of cholesterol metabolism and plasma plant sterols with the severity of coronary artery disease1s⃞

Journal of Lipid Research, 2009
Changes in the balance of cholesterol absorption and synthesis and moderately elevated plasma plant sterols have been suggested to be atherogenic. Measuring cholestanol, lathosterol, campesterol, and sitosterol, we investigated the relationships of ...

The Metabolism of Cholestanol, Cholesterol, and Bile Acids in Cerebrotendinous Xanthomatosis [PDF]

Journal of Clinical Investigation, 1973
The metabolism of cholesterol and its 5-dihydro derivative, cholestanol, was investigated by means of sterol balance and isotope kinetic techniques in 3 subjects with cerebrotendinous xanthomatosis (CTX) and 11 other individuals. All subjects were hospitalized on a metabolic ward and were fed diets practically free of cholesterol and cholestanol. After

Phytochemicals in Asthma Management: Mechanism, Translational Gap and Clinical Integration

Phytochemicals in Food and Medicine, Volume 1, Issue 2, June 2026.
The phytochemicals including flavonoids, alkaloids, terpenoids, and saponins modulate inflammatory, oxidative, and immune pathways in asthma. It highlights their mechanisms of action, translational challenges, advanced formulation strategies, and emerging clinical potential as adjunct therapies for precision‐based asthma management.

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

Functional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.

Highly sensitive analysis of sterol profiles in human serum by LC-ESI-MS/MSs⃞

Journal of Lipid Research, 2008
We have developed a highly sensitive and specific method for the analysis of serum sterol profiles. Sterols in 1 μl of dried serum were derivatized into picolinyl esters (3β-picolinate) and analyzed by liquid chromatography-tandem mass spectrometry (LC ...

Fine-mapping, mutation analyses, and structural mapping of cerebrotendinous xanthomatosis in U.S. pedigrees

Journal of Lipid Research, 2001
Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder of bile acid biosynthesis. Clinically, CTX patients present with tendon xanthomas, juvenile cataracts, and progressive neurological dysfunction and can be diagnosed by the ...

The Genetic Landscape of Hereditary Spastic Paraplegia in Greece

Clinical Genetics, Volume 109, Issue 5, Page 837-846, May 2026.
We investigated 112 Greek index‐cases with hereditary spastic paraplegia collected over > 25 years using NGS and MLPA. We identified a causative variant in 68 patients (60.7%), including 7 novel causative variants. This study presents a comprehensive overview of the phenotypic and genotypic spectrum of HSP in the Greek population.
