W artykule podjęto się nieformalnego zdefiniowania kategorii przekąsek ekstrudowanych, oraz w skrócie zaprezentowano dane dotyczące ich konsumpcji. Omówiono również proces produkcyjny, a także kierunki rozwoju obserwowane na rynku europejskim. Przedstawiono i omówiono typy obecnie stosowanych ekstruderów. Wiele uwagi poświecono sposobom projektowania i modernizacji linii technologicznych, czyli stosowaniu maszyn modułowych. Przedstawiono również prognozę przyszłych kierunków rozwoju branży, opartych na badaniach nad urozmaiceniem produktów pod względem smaku, kształtu i koloru oraz wartości odżywczych i wpływu na zdrowie konsumenta.
Nowe rozporządzenie Parlamentu Europejskiego i Rady (WE) nr 1169/2011 w sprawie przekazywania informacji konsumentom pozwala na stosowanie dodatkowych form oznakowania wartością odżywczą na froncie opakowania. W artykule omówiono warunki, jakie powinny być spełnione zanim umieści się na opakowaniu uproszczone formy oznakowania. Przedstawiono też przegląd form, schematów, logotypów i ikon stosowanych w różnych krajach europejskich oraz wskazówki interpretacyjne i informacje dotyczące ostatnich dyskusji odbywających się na forum wspólnotowym na temat brytyjskiego systemu hybrydowego.
The aim of the studies conducted in 2012-2013 was to compare the chemical composition of essential oils isolated from wild thyme (Thymus serpyllum L.) by hydrodistillation in Deryng and Clevenger apparatus. GC-MS analysis of the isolated oils revealed that carvacrol (42.81– 45.24%), γ-terpinene (7.68–9.04%), β-caryophyllene (5.28-9.10%), β-bisabolene (5.76–6.91%) and carvacrol methyl ether (4.92–6.09%) were the major components of all the samples. On the basis of the obtained data it was proved that the type of distillation apparatus had no significant effect on the content of the main essential oil constituents of wild thyme. However, based on the means for both years of the study it was proved that hydrodistillation in Deryng apparatus was more effective for carvacrol concentration, while in Clevenger apparatus – for γ-terpinene and carvacrol methyl ether concentration. The type of distillation apparatus had no significant effect on the content of the other essential oil constituents.
Background: Human milk is the optimal nutrition for newborns and infants during the first period of their life – from birth to 6-th month. It contains a uniquely quantitative and qualitative balanced nutrients profile. Composition of breast milk is dynamic and may vary according to maternal nutritional status. Objective: The aim of this study was to investigate associations between human milk composition and maternal nutritional status. Material and methods: One-day milk samples were provided by exclusively breastfeeding mothers (n=40) at the first month of lactation. Protein – total and true, fat, carbohydrate, dry matter and energy content were determined using the Human Milk Analyzer by MIRIS. The anthropometric measurements (current body weight, height) were used to calculate current body mass index (BMI). On this basis, we assessed nutritional status of examined population. Results: For the majority of women (75%, n=30) currently BMI value was in range of 18.5-24.9 kg/m2, for the rest of women it was ≥ 25 kg/m2. The median macronutrient composition per 100 ml of mature breast milk was 7.0 g for carbohydrate, 1.1 g for protein, 3.5 g for fat, 11.9 for dry matter and energy content was 66.0 kcal. Maternal body mass index was positively related to lipid, dry matter and energy breast milk content (p<0.05). Conclusions: The majority of examined women in the first month of lactation was in normal state of nutrition. For the rest of women BMI values indicated for overweight. Our results confirm correlation between human milk composition and maternal nutritional status, especially in matters of energy value and fat content in human milk.
Background. In case of shortage of breast milk despite proper lactation care or the poor state of the mother’s health, breast milk from human milk bank is recommended for feeding preterm infants. Objective. This study retrospectively evaluated the first year of the operation of the Regional Human Milk Bank. Material and methods. Data concerning donors was collected in the human milk bank during the cooperation. The clinical characteristics of the recipients was made on the basis of medical documentation from the Holy Family Hospital in Warsaw, Poland. Analysis of nutritional value was performed with the human milk analyzer (MIRIS AB). Results. In the first year of activity, 45 voluntary donors established cooperation, donating from 650 to 32030 ml of human milk. The content of nutrients in milk provided by donors was variable - protein 0.4-1.5 g / 100 ml, fat 1.1-7.4 g / 100 ml, carbohydrates 6.3-7.9 g / 100 ml. The average length of using donated human milk was 4 days and the average volume of milk for one infant was 282 ml. Conclusions. The donor profiles have a significant impact on the milk composition form HMB. The nutritional value can be improved by recruitment donors from mothers that gave birth prematurely and by beginning donation at earlier stages of lactation as soon as lactation is stabilized. In case of shortage of mothers own milk the immediate implementation of donors milk as a short-term support can significantly reduce the food intolerance incidence in the group of prematurely born infants
Marble burying test (MBT) is an animal model of anxiety and obsessive-compulsive disorder, used as a screening test for new compounds in modern drug development. The aim of this study was to introduce that method to experimental workshop of the Clinical Pharmacy Department. MBT was carried out according to the procedure of Broekkamp et al. (1986). The first stage of the work was to determine the relevant parameters such as time of observation, age and body weight of mice. It was assumed that a 30-minute observation period and higher body weight of mice, i.e. 26–30 g are favorable parameters for the assessment of anxiolytic-like activity in MBT. The next step was to investigate properties of six reference compounds from different pharmacological groups: benzodiazepines (BZD), antidepressants (SSRI, TCA), typical and atypical antipsychotics. The selection was based on the literature data indicating anxiolytic-like activity of those drugs in MBT. The results show that diazepam (BZD) and escitalopram (SSRI) were active at both doses of 2.5 and 5.0 mg/kg; imipramine (TCA) was active at a dose of 30 mg/kg; olanzapine and aripiprazole (atypical antipsychotics)displayed anxiolytic-like activity at both doses of 2.5 and 5.0 mg/kg; chlorpromazine (typical antipsychotic) was active at doses of 1.25 and 2.5 mg/kg. To verify the impact of locomotor activity on animals’ behavior in MBT, the effect of active doses on spontaneous locomotor activity was also examined. Olanzapine, aripiprazole and chlorpromazine, given at active doses decreased locomotor activity of mice whereas other drugs had no effect on that parameter.
Urinary creatinine to serum creatinine (UCr/SCr) ratio and renal failure index (RFI) are useful indices of renal damage. Both UCr/SCr ratio and RFI are used in differentiation between prerenal azotaemia and acute tubular necrosis. In this work the authors calculated the UCr/SCr ratio and RFI in dogs infected with Babesia canis and the values of these indices in azotaemic dogs infected with the parasite. The results of this study showed significantly lower UCr/SCr ratio in dogs infected with B. canis than in healthy dogs. Moreover, in azotaemic dogs infected with B. canis the UCr/SCr ratio was significantly lower and the RFI was significantly higher than in non-azotaemic dogs infected with B. canis. The calculated correlation between RFI and duration of the disease before diagnosis and treatment was high, positive and statistically significant (r = 0.89, p < 0.001). The results of this study showed that during the course of canine babesiosis caused by B. canis in Poland acute tubular necrosis may develop.
Zakres badań obejmował przeprowadzenie syntezy poli(kwasu itakonowego) na drodze polimeryzacji wolnorodnikowej w obecności inicjatora – nadsiarczanu amonu w różnych mediach reakcyjnych oraz w różnej temperaturze. Przeprowadzono polimeryzację w układach wodnych zawierających chlorek choliny oraz w mieszaninach eutektycznych monomer – chlorek choliny sporządzonych w różnych proporcjach. Zbadano wpływ zmiennych parametrów reakcji na wydajność procesu, skład elementarny oraz strukturę chemiczną otrzymanych polimerów. Charakterystykę produktu wykonano przy użyciu technik spektroskopowych FTIR oraz NMR.
