Varietal dependence of chemoprotective substances in fresh and frozen spinach (Spinacia oleracea, L.)

Spinach (Spinacia oleracea L.) is an important source of bioactive compounds. It is commonly consumed fresh or frozen products. Spinach is rich sources of polyphenols, it is a good source of vitamin C and has potential beneficial properties for human health. This study provides some knowledge about content of total polyphenols, and antioxidant activity in selected varieties of fresh and frozen spinach samples. Four spinach cultivars (̓Boa ̓, ̓ Hudson ̓, ̓Chica ̓, ̓Trombone ̓) were analysed. The content of the total polyphenols (TPC) was determined by the Folin-Ciocalteu reagent (FCR). Antioxidant activity (AA) was measured using a compound DPPH (2,2-diphenyl-1-picrylhydrazyl). The content of total polyhenols in fresh samples of spinach ranged from 975 ±97.15 mg.kg-1 to 1493 ±50.42 mg.kg-1 and values of antioxidant activity were in interval from 77.55 ±0.34% to 82.57 ±0.83%. The highest level of TP content in fresh spinach was recorded in variety Hudson (1493 mg.kg-1) and the lowest in variety Chica (975 mg.kg-1). Between these varieties statistically significant difference in the content of total polyphenols was found. The highest value of antioxidant activity in fresh spinach was recorded in variety Trombone (82.57%) and the lowest in variety Boa (78.59%). This difference was also statistically significant. The highest level of TP content in frozen spinach samples was found in variety Hudson (1749 mg.kg-1) and the lowest in variety Chica (855 mg.kg-1). The values of antioxidant activity in frozen spinach samples were in range from 45.86 ±7.84%to 79.67 ±0.88%. The highest value of antioxidant activity in frozen spinach was found in variety Hudson (79.67%) and the lowest in variety Chica (45.86%).

Diplomová práce porovnává postoj ke snižování nezaměstnanosti prostřednictvím aktivní politiky zaměstnanosti v ČR a VB. VB má jednu z nejnižších měr nezaměstnanosti, a proto je zajímavé, porovnávat ji se zemí, která má míru nezaměstnanosti velmi vysokou. První kapitoly se týkají teorie aktivní politiky zaměstnanosti obecně, řešení APZ v každém státě zvlášť, i jaký postoj má k nezaměstnanosti EU. V ostatních kapitolách jsou na základě SWOT analýzy porovnávány silné a slabé stránky a příležitosti a hrozby obou států ? míra nezaměstnanosti, rizikové skupiny, vzdělání, instituce trhu práce aj. Na závěr je nutná komparace obou států a především nastínění určitých doporučení pro ČR

Influence of age, body condition score and gravidity on selected endocrine, biochemical and haematological parameters of Noriker mares in the second trimester of gravidity

SUMMARY Background: Many haematological, biochemical and endocrine parameters may vary depending on breed, sex, age, reproductive status, body condition score, type of load, nutrition and welfare. Objectives: The aim of our study was to analyse the influence of age, body condition and reproductive state on selected biochemical, haematological and endocrine parameters in mares of Norik breed. Materials and Methods: The research was conducted on 22 broodmares of Norik breed. The mares were classified according to the age, reproductive state and body condition into 6 groups (group A:– from 5 to 10 years of age (n = 6), group B: from 11 to 17 years of age (n = 16), group C: mares in the second trimester of pregnancy (n = 11), group D: non-pregnant mares (n = 11), group E: mares with optimal weight (n = 16), group F: overweight mares (n = 6). Results and Discussion: It seems that the body condition is a more objective system of evaluating the selected biochemical, haematological and endocrine parameters in mares as compared to the criterion of age and pregnancy. As compared group E to group F, significant differences were found in IGF-1 (p ≤ 0,17), glucose (p < 0,01), urea (p < 0,05), albumin (p ≤ 0,1), creatinine (p ≤ 0,08 ), AST (p ≤ 0,1), GMT (p ≤ 0,18), LDH (p ≤ 0,09), total cholesterol (p ≤ 0,12), iron (p < 0,05), chlorine (p < 0,05), RBC (p ≤ 0,1) and Hb (p ≤ 0,14). For this reason, in case of the assessment of a very heterogeneous group of horses, we can hypothesized that the mares should be divided according their BCS when the evaluation of biochemical, haematological and hormonal parameters is performed

Prevalence of Dichelobacter nodosus and Fusobacterium necrophorum on dairy farms in Slovakia

ABSTRACTThe aim of this study was to determine the prevalence of bacteria Dichelobacter nodosus (D. nodosus) and Fusobacterium necrophorum (F. necrophorum) in non-lame dairy cows on eight Slovak dairy herds. In total, 1,631 Holstein Friesian dairy cows were included in the study. Information of the cows was collected from on-farm software included cow ID, lactation number (heifer/cow), year milk yield (kg), and DIM on collection date. The PCR method detected D. nodosus and F. necrophorum on the feet of 1,394 (85.5%) and 373 (22.1%) dairy cows, respectively (p < 0.05). No dairy farm could be found without positive samples for D. nodosus and the majority of the farms were free or had very low prevalence of F. necrophorum (0–9.1%). Statistical difference for the prevalence of D. nodosus and F. necrophorum in different Slovak regions was detected for both strains. Logistic regression revealed an association between both D. nodosus and F. necrophorum identification and annual milk production (odds ratios = 0.69 and 0.32, respectively). Our data demonstrates that D. nodosus is present on the feet of almost every dairy cow what means a potential risk for cattle to develop foot rot. Furthermore, both bacteria are associated with decreased annual milk production

Coherent J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at √sNN=2.76 TeV

The ALICE Collaboration has made the first measurement at the LHC of J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at sNN=2.76 TeV. The J/ψ is identified via its dimuon decay in the forward rapidity region with the muon spectrometer for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 55 μb−1. The cross section for coherent J/ψ production in the rapidity interval −3.6<y<−2.6 is measured to be dσJ/ψcoh/dy=1.00±0.18(stat)−0.26+0.24(syst) mb. The result is compared to theoretical models for coherent J/ψ production and found to be in good agreement with those models which include nuclear gluon shadowing
