Vitamin D3 in fish oil extracted with limonene from anchovy leftovers
2020
Abstract Aiming to identify and assess the amount of fat-soluble vitamins in anchovy oil extracted with d-limonene from anchovy fillet leftovers via the UHPLC–HESI–MS advanced mass spectrometry analytical technique, this study shows that only vitamin D3 is present in anchovy by-product oil. The sum of the quantities of the three isomers of vitamin D3 amounts to 0.0815 μg vitamin D3 per g oil, namely a 81.5 μg/kg content, in good agreement with the typical amounts of vitamin D3 in fish oils (ranging from 18 to 350 μg/kg).
Density Functional Theory Calculated Raman Spectra of Ergocalciferol (Vitamin D2) and Cholecalciferol (D3)
2021
Density functional theory (DFT)-calculated Infrared and Raman spectra of Vitamin D2 and D3 are presented. The calculated results are compared with each other and with available experimental data. Applicability of Raman spectra for non-invasive optical Vitamin D sensors is discussed.
Use of nutritional supplement to improve performance in professional soccer players: A case report
2020
The aim of the study was to investigate the intake percentage and the satisfaction level of some nutritional supplements used by professional soccer players. Twenty-nine professional soccer players (age: 24.6 ± 5.2 years, body weight: 79.2 ± 4.9 kg, body height: 1.83 ± 0.05 m) belonging to a team of Serie A were interviewed on: frequency of use, tolerability, and acceptance of the supplements (creatine, β-alanine, whey protein, nitrates, vitamin D3, caffeine) proposed by the nutritionist team. This survey revealed a great inter-individual variability on the intake of the proposed supplements. All respondents (n = 29) said they take cholecalciferol (vitamin D3), 17 out of 29 creatine, 14 out…
Begleitende Inhaltsstoffe in 22 OTC-Fischöl- und Lebertranpräparaten: Cholesterin, Schwermetalle und Vitamin A
1989
Fischolkapseln werden von selbstmedizierenden Patienten in zunehmendem Mase eingenommen. Hier wurde der Frage nachgegangen, ob 22 kommerziell erhaltliche Fischol- und Lebertranzubereitungen Begleitsubstanzen enthalten, deren Menge unter Umstanden nachteilig fur den Patienten sein konnten. Gemessen wurden: Cholesterin mit der Gaschromatographie, Schwermetalle mittels Atomabsorption und Vitamin A mit der hochauflosenden Flussigkeitschromatographie (HPLC). Sowohl der Cholesterin-als auch der Schwermetallgehalt lagen in unbedenklichen Bereichen. Der Vitamin-A-Gehalt von Lebertrankapseln wurde jedoch in Mengen gefunden, bei denen schwangere Frauen die Dosierungsempfehlungen der Hersteller nicht …
Vitamin D Sources, Metabolism, and Deficiency: Available Compounds and Guidelines for Its Treatment
2021
Studies on vitamin/hormone D deficiency have received a vast amount of attention in recent years, particularly concerning recommendations, guidelines, and treatments. Moreover, vitamin D’s role as a hormone has been confirmed in various enzymatic, metabolic, physiological, and pathophysiological processes related to many organs and systems in the human body. This growing interest is mostly due to the evidence that modest-to-severe vitamin D deficiency is widely prevalent around the world. There is broad agreement that optimal vitamin D status is necessary for bones, muscles, and one’s general health, as well as for the efficacy of antiresorptive and anabolic bone-forming treatments. Food su…
α-Tocopherol Modulates Phosphatidylserine Externalization in Erythrocytes
2006
Objective— The aim of the present study was to assess the effect of α-tocopherol, the main vitamin E isomer on phosphatidylserine (PS) exposure at the surface of circulating erythrocytes, and to determine consequences on erythrocyte properties. Methods and Results— In vitro α-tocopherol enrichment of isolated erythrocytes significantly decreased PS externalization as assessed by lower Annexin V-fluorescein isothiocyanate labeling. Plasma phospholipid transfer protein (PLTP) transfers vitamin E, and both α-and γ-tocopherol accumulated in circulating erythrocytes from PLTP-deficient homozygous (PLTP −/− ) mice as compared with wild-type mice. In agreement with in vitro studies, vitamin E–enr…
J15 Validation Of 24 H Dietary Recalls To Assess Dietary Intake For Patients With Huntington's Disease. Spanish Multicenter Study Of The European Gro…
2014
Background Weighed dietary records are considered as the gold standard in nutrition assessment, but 24 h dietary recalls (24-h) and 3 days dietary record (3-d) are usually used. The 24-h is less laborious and cheaper but is necessary to have an experienced interviewer; while the 3-d are completed by the same participant/caregiver, it is more reliable but more expensive, time consuming is high, require previous training and have more dropouts. Our aim was to compare the two procedures to assess dietary intake in HD. Objectives To validate a 24-h vs 3-d to assess dietary intake for patients with HD. Methods Spanish multicenter, longitudinal study (EHDN). A 24-h was administered (with a one-mo…
Simulating mechanical consequences of voluntary movement upon whole-body equilibrium: the arm-raising paradigm revisited.
2001
Voluntary arm-raising movement performed during the upright human stance position imposes a perturbation to an already unstable bipedal posture characterised by a high body centre of mass (CoM). Inertial forces due to arm acceleration and displacement of the CoM of the arm which alters the CoM position of the whole body represent the two sources of disequilibrium. A current model of postural control explains equilibrium maintenance through the action of anticipatory postural adjustments (APAs) that would offset any destabilising effect of the voluntary movement. The purpose of this paper was to quantify, using computer simulation, the postural perturbation due to arm raising movement. The m…
Voriconazole and the liver.
2015
Voriconazole is an azole useful for the prophylaxis and the treatment of aspergillosis and other fungal infections in immunosuppressed subjects, as those found in aplasia after aggressive polychemotherapy treatments, after hematopoietic stem cell, liver or lung transplantation. Its administration in therapeutic doses lead to extremely varied serum levels from patient to patient and even to the same patient. The explanations are varied: nonlinear pharmacokinetics, certain patient-related factors, including genetic polymorphisms in the cytochrome P450 2C19 gene, the kidney and liver function, simultaneous administration with other drugs metabolised by the same cytochrome. It is recommended to…
Birth weight, cardiometabolic risk factors and effect modification of physical activity in children and adolescents: pooled data from 12 internationa…
2020
Abstract Objectives Low and high birth weight is associated with higher levels of cardiometabolic risk factors and adiposity in children and adolescents, and increases the risk of cardiovascular diseases, obesity, and early mortality later in life. Moderate-to-vigorous physical activity (MVPA) is associated with lower cardiometabolic risk factors and may mitigate the detrimental consequences of high or low birth weight. Thus, we examined whether MVPA modified the associations between birth weight and cardiometabolic risk factors in children and adolescents. Methods We used pooled individual data from 12 cohort- or cross-sectional studies including 9,100 children and adolescents. Birth weigh…
