The present work describes the results of research of a complex of substances obtained from sedimentary wine yeast by extraction with food extractants with the use of ultrasound. The filtrates of alcoholic extracts of yeast and sediments isolated from filtrate were investigated. It has been shown that hydrophobic substances moderately soluble and poorly soluble in alcohol, such as ethyl esters of fatty acids, fatty acids, phospholipids, sterols, squalene, were isolated from sedimentary wine yeast by extraction with alcohol-containing extractants. The mechanical effect of ultrasound provides faster and more complete penetration of the solvent into the intracellular substances. Ultrasound allows one to achieve greater penetration of the solvent into plant tissues and improve mass exchange. Ultrasonic waves, causing cavitation in the liquid, destroy cell walls and promote the release of cell matrix components. Thus, during the US treatment of suspended sedimentary wine yeast a mixture of fatty acid ethyl ester more than 2 times and squalene - 1.5 times, compared to the control, is observed.

Abstract This review includes a description of short-term and long-term markers of ethanol intake and their clinical utility. The major portion of this report is a summary of studies on fatty acid ethyl ester, a new marker for monitoring both acute and chronic ethanol intake. With the markers described in the review, algorithms to assess recent ethanol intake, chronic ethanol intake, and end organ damage are included to provide a practical approach to the evaluation of the patient.

Fatty acid ethyl ester (FAEE) merupakan salah satu biomarker konsumsi etanol. Penelitian ini bertujuan untuk menganalisis senyawa FAEE dalam sampel rambut secara kualitatif dengan GC-MS. Pada penelitian ini dibuat campuran standar FAEE (Etil Pamlitat dan Etil Oleat) 100 ppm dengan perbandingan 1:1 kemudian dibuat variasi konsentrasi. Metode validasi standar FAEE diukur menggunakan GC-MS. Sampel rambut dipreparasi dengan cara didekontaminasi kemudian diekstraksi dan diinjeksikan ke sistem GC-MS. Hasil validasi diperoleh persamaan regresi linier yaitu, y = 240713,507x-147471,2353 untuk etil palmitat dan y = 58361,45x+242,5 untuk etil oleat dengan nilai koefisien korelasi (r2) berturut-turut sebesar 0,9996 dan 0,9999. Batas deteksi diperoleh sebesar 2,5522 ppm dan 0,0189 ppm, dengan batas kuantitasi sebesar 8,5073 ppm dan 0,0630 ppm. Nilai koefisien variansi diperoleh sebesar 3,59% dan 8,65 x 10-4%, dengan persen perolehan kembali sebesar 100,05% dan 100,08%. Hasil analisis menunjukkan, sampel rambut semua sukarelawan mengandung etil palmitat dan etil oleat pada waktu retensi 22,03 menit dan 23,83 menit.

Day By Day

Producing an efficient alternative renewable fuel for power generation is the solution for today’s power crisis. As the oil prices are increasing day- by- day and the fossil fuels are depleting, why to rely on the fossil fuels for energy?. One of the alternative fuels is bio-fuel which can be obtained from sewage, garbage and waste vegetable oils which would otherwise be difficult to dispose leading to pollution. Biodiesel is a substitute for petroleum-based diesel which is derived from vegetable oils by the process of trans-esterification. Biodiesel is prevalently used as automobile fuel. Ethyl esters produced by trans-esterification can be used for rural electrification. In this paper, the electrified quality output obtained using different blends of ethyl ester with diesel and the efficiencies for each blend and pure diesel are studied and the results show that power generation using ethyl ester for rural population will be efficient, reliable and economical.

Abstract Fatty acid ethyl esters (FAEE), esterification products of ethanol and fatty acids, have been implicated as mediators of ethanol-induced organ damage. Because cytosolic enzymes such as aspartate aminotransferase, lipase, and amylase appear in the blood after liver or pancreatic damage, we hypothesized that FAEE synthase, which is both cytosolic and membrane bound, is also released into the blood of patients with liver or pancreatic disease. We used a method involving thin-layer chromatography coupled with gas chromatography-mass spectrometry to reliably identify and quantify FAEE. In this study, we demonstrated that patients with liver or pancreatic disease release FAEE synthase into their plasma in amounts proportional to the amount of aspartate aminotransferase (r = 0.78), amylase (r = 0.65), and lipase (r = 0.63). These data indicate that liver and pancreatic damage results in release of FAEE synthase into the blood. The presence of FAEE synthase in plasma permits nonoxidative ethanol metabolism in the plasma.
