The influence of dietary conjugated linoleic acid (CLA) isomers (CLAmix) and/or Se as Na2SeO3 (SeIV) or selenized yeast (SeY) on the relative body weight gain (RBWG) of rats, pancreas weight, concentrations of CLA isomers and of other fatty acids (FA) in the pancreas were studied. For 6 weeks, female Wistar rats (aged 8 weeks) were fed ad libitum the Labofeed H diet enriched in 1.5% CLAmix, 0.2 ppm Se (LSe), 0.5 ppm Se (HSe) as SeIV (i.e. LSeIV or HSeIV, respectively), or SeY (i.e. LSeY or HSeY, respectively). Each group contained eight rats. The results documented that dietary LSeIV and CLAmix most effectively increased the RBWG of rats and feed conversion efficiency, while the diet with HSeIV most efficiently increased pancreas weight compared with the control rats. The diets enriched in CLAmix and Se as SeIV or SeY increased the sum of saturated fatty acids (SFA), the atherogenic SFA, A-SFA index, thrombogenic SFA (T-SFA), and the T-SFA index in the pancreas of rats compared with the control group. The diets containing CLAmix and Se as SeIV or SeY stimulated the accumulation of cis9trans11CLA, trans10cis12CLA, as well as the sum of all CLA isomers in the pancreas compared with rats fed the diet enriched in CLAmix. These diets increased the concentration of n-6 polyunsaturated FA (n-6 PUFA) and decreased the level of long-chain n-6 PUFA (Ln-6 PUFA) in the pancreas compared with the control rats and rats fed the diets with SeIV or SeY. The diets containing CLAmix and Se (as SeIV or SeY) increased the concentration of n-3 PUFA and Ln-3 PUFA in the pancreas compared with the control rats. Our study findings documenting that dietary Se and/or CLAmix and Se (as SeIV or SeY) considerably increased the concentration of PUFA, especially n-3 PUFA, improved the n-6 PUFA/n-3 PUFA ratio in the pancreas are valuable information for scientists carrying out research to improve animal and human health.
Decalepis hamiltonii Wight & Arn., is a plant species that is endemic to southern parts of India. The aim of this study is to explore the influence of habitat heterogeneity on total phenolics, flavonoids, flavor compound 2-hydroxy-4-methoxy benzaldehyde (2H4MB) and antioxidant potential of tubers. The flavor metabolite 2H4MB was quantified by HPLC using isocratic solvent system (methanol : acetonitrile : water : acetic acid 47 : 10 : 42 : 1) that indicates obvious difference in 2H4MB content of tubers with a maximum of 96.4 ±2.6 and 92.6 ±1.2 mg 100 g–1 dry weight basis (DW) in samples from B.R. Hills and Mysore area of Karnataka, followed by samples from Tirumalai Hills and Kurnool from Andhra Pradesh (89.02 ±0.9 mg 100 g–1 DW), Tamil Nadu (81.6 ±2.4 mg 100 g–1 DW) and Kerala (80.18 ±1.1 mg 100 g–1 DW) of tubers. There was variation in total phenolics, total flavonoids and 2H4MB content of root samples collected from different habitats. Also significant variation in free radical scavenging potential of methanol root extracts was noticed, which is directly proportional to the phenolics, and flavonoids content. Overall, there was 10–16% difference in content of 2H4MB in D. hamiltonii tubers that were collected from different natural habitats, and this habitat heterogeneity has to be considered vital, while using such tubers for edible purposes and food formulations.
Przedstawiono wyniki oceny porównawczej wskaźników kumulacji funkcjonalnej izomerów 2,3-, 2,4- i 2,6-dinitrotoluenu (DNT). Izomer 2,3- oraz 2,4-DNT zaliczono do pierwszej, a 2,6-DNT do drugiej klasy związków kumulujących efekty toksyczne.

Unsaturated trans fatty acid - nutritional problem?

44%
This review summarizes the up-to-date data on the consumption pattern of trans fatty acids in different countries including Poland, as well as the metabolism and metabolic effects of trans fatty acids in human organism. The health hazards linked with the consumption of trans fatty acids are also discussed.
