Determination of 3-MCPD by GC-MS/MS with PTV-LV injector used for a survey of Spanish foodstuffs
2007
3-Monochloropropane-1,2-diol (3-MCPD) is the most common chemical contaminant of the group of chloropropanols. It can occur in foods and food ingredients at low levels as a result of processing, migration from packaging materials during storage and domestic cooking. A sensitive method for determination of 3-MCPD in foodstuffs using programmable temperature vaporization (PTV) with large-volume injection (LVI) gas chromatography (GC) with tandem mass spectrometry detection (MS/MS) has been developed and optimized. The optimization of the injection and detection parameters was carried out using statistical experimental design. A Plackett-Burman design was used to estimate the influence of reso…
Untersuchungen über die chronische Toxizität der Ascorbinsäure bei der Ratte
1963
Bei einer chronischen Verabreichung (10 Wochen) von 6,5 g Ascorbinsaure je kg Korpergewicht per os wurden bei der Ratte keine schadlichen Wirkungen beobachtet, selbst wenn die Tiere einer Stressituation (4 Wochen dauernde eiweisarme Ernahrung) unterworfen wurden. Tagesdosen von 27,3 g/kg Korpergewicht erwiesen sich als sicher toxisch. Die Mortalitatsrate betrug bei dieser Dosierung 77% innerhalb von 4 Wochen. Auf Grund dieser Versuche kann man als oberste Grenze der Vertraglichkeit bei chronischer Zufuhr 10 g Ascorbinsaure je kg Korpergewicht annehmen. Unter Zugrundelegung dieser Zahl ergibt sich fur die als wunschenswert erachtete Tagesdosis von 75 mg fur den Menschen eine Sicherheitsspann…

The occurrence and dietary exposure assessment of 16 mycotoxins, 6 biogenic amines (BAs), and 13 metallic elements in blue-veined cheeses (n = 46) is reported. Co-occurrence of mycophenolic acid (&le
Nutrition Knowledge Is Associated with Energy Availability and Carbohydrate Intake in Young Female Cross-Country Skiers
2021
The aim of this study was to provide information on energy availability (EA), macronutrient intake, nutritional periodization practices, and nutrition knowledge in young female cross-country skiers. A total of 19 skiers filled in weighted food and training logs before and during a training camp. Nutrition knowledge was assessed via a validated questionnaire. EA was optimal in 11% of athletes at home (mean 33.7 ± 9.6 kcal·kgFFM−1·d−1) and in 42% at camp (mean 40.3 ± 17.3 kcal·kgFFM−1·d−1). Most athletes (74%) failed to meet recommendations for carbohydrate intake at home (mean 5.0 ± 1.2 g·kg−1·d−1) and 63% failed to do so at camp (mean 7.1 ± 1.6 g·kg−1·d−1). The lower threshold of the pre-ex…
Utilization of mulberry leaves (Morus latifolia cv. Kokusou 21) in diets for dairy ewes
2009
Twelve Valle del Belice lactating ewes were divided into three homogeneous groups and fed ad libitum the following diets in a 3 x 3 Latin square design: sulla hay (HA); sulla hay and Mulberry leaves (M. leaves) (HM); M. leaves (MU). DM intake of MU ewes was lower than that of HM ewes, with an intermediate level for HA ewes. HM ewes showed to prefer M. leaves to hay, but their need to balance the high protein and low NDF contents of M. leaves by eating hay also emerged. Milk yield increased as the dietary content of M. leaves increased- In addition, the use of HM and MU diets led to higher milk fat and urea content in comparison with the HA diet. The results confirmed that M. leaves are a su…
Synthesis and X-ray Crystal Structure Analysis of Substituted 1,2,4-Triazolo [4’,3’:2,3]pyridazino[4,5-b]indole and Its Precursor
2023
The hit compound 1,2,4-triazolo[4’,3’:2,3]pyridazino[4,5-b]indole 3 was synthesized from the reflux of 4-amino-5-indolyl-1,2,4-triazole-3-thione 1 with 4′-bromoacetophenone 2 in methanol catalyzed by concentrated HCl and the desired final molecule was obtained by recrystallization from methanol. The suggested structures of compounds 1 and 3 based on the spectral characterizations were confirmed by X-ray single crystal diffraction analysis. Compound 3 crystallized in the triclinic crystal system and P-1 space group with a = 5.9308(2) Å, b = 10.9695(3) Å, c = 14.7966(4) Å, α = 100.5010(10)°, β = 98.6180(10)°, and γ = 103.8180(10)°. On the other hand, the crystal system of 1 is monoclinic, whe…

Deficiency of Vitamin C in Dairy Products and Supplementation in Milk by Adding the Bioactive Natural Products
2011
Since milk constitutes an important item in the human diet and since the importance of an adequate amount of vitamin C in the diet is becoming more fully appreciated, it appeared to us that any investigation that might yield further information as to how milks containing greater quantities of this dietary essential might be produced would be worth while. Sea buckthorn is a natural multi-vitamins and a major source of vitamin C, fruits containing vitamin C at a rate of two times more than rosehips and ten times more than citrus (200-1500 mg). Strengthening with Vitamin C will be considering of content of vitamin C in milk samples taken per season (winter, spring, summer, autumn). This contri…
Chemical Aspects of Human and Environmental Overload with Fluorine
2021
Over the last 100-120 years, due to the ever-increasing importance of fluorine-containing compounds in modern technology and daily life, the explosive development of the fluorochemical industry led to an enormous increase of emission of fluoride ions into the biosphere. This made it more and more important to understand the biological activities, metabolism, degradation, and possible environmental hazards of such substances. This comprehensive and critical review focuses on the effects of fluoride ions and organofluorine compounds (mainly pharmaceuticals and agrochemicals) on human health and the environment. To give a better overview, various connected topics are also discussed: reasons an…
