BACKGROUND Little is known about the intensity of oxidative damage in human milk resulting from maternal oxidative stress. The aim of our study was to explore the changes in Total Antioxidant Status (TAS) and concentrations of antioxidative vitamins and isoprostanes (markers of oxidative stress) in human colostrum and mature milk. METHODS The study(More)
European beavers (Castor fiber) from two regions were examined to identify exposure to persistent environmental contaminants. A reference group was comprised of six animals from the Forest Division of Srokowo, and an exposed group was comprised of five animals from the vicinity of a former military airport operated in 1918–1986—both from Warmia land in(More)
The aim of this study was to determine the concentrations of alpha- and gamma-tocopherols in human breast milk samples from different periods of lactation and to compare them with tocopherol content in commercially available formulas for infants at corresponding ages. The study included 93 breast milk samples obtained on the 2nd (colostrum, n = 17), 14th (n(More)
INTRODUCTION The Total Antioxidant Capacity (TAC) of human milk reflects the concentration and the activity of many components which prevent oxidative degradation of fats and proteins. This study compares the effectiveness of ABTS and DPPH tests with regard to the recovery, precision and sensitivity (detection and quantification limit) of (TAC) values in(More)
AIM We hypothesized that the fatty acid composition of breast milk can be affected by a smoking habit in the mother. Consequently, this study verified whether maternal smoking modulates, and if so to what extent, the breast milk fatty acid profile. METHODS The study included 20 postpartum women who declared smoking more than five cigarettes daily(More)
UNLABELLED Breastfeeding is the optimal way of feeding infants and young children. For the human infant, very important ingredients of milk are fatty acids (FA), including long-chain polyunsaturated fatty acids LC-PUFA, which are necessary for the development of human nervous system. The aim of this study was to determine the content and composition of FA(More)
We verified whether smoking during lactation influences breast milk cytokine (interleukin [IL]-1α, IL-1β, IL-6, IL-8, IL-10, and tumor necrosis factor-α) levels 30 to 32 days after delivery. The study group comprised 24 postpartum women who declared smoking >5 cigarettes per day. The control group included 45 nonsmoking postpartum women. Compared with(More)
BACKGROUND The phytochemicals of two apple cultivars (Yellow Transparent and Early Geneva) protected in two ways, conventionally with chemical pesticides or by effective microorganisms (EM), were compared. Two types of components were determined: lipids synthesised constitutively and generated via inducible pathways polyphenols along with antioxidant(More)
The fatty acid (FA) composition of depot adipose tissues in the raccoon dog (Nyctereutesprocyonoides) and the European beaver (Castorfiber) differs from that reported for the lipids of other monogastric animals, especially with regard to the presence of trans-octadecenoic acids. The concentrations of pentadecanoic acid 15:0 (PA) and heptadecanoic acid 17:0(More)
