  • Internationalization and Quality Assurance in Higher Education
    Publikacja

    - Management - Rok 2022

    Internationalization is an inevitable phenomenon among all contemporary higher education institutions (HEIs) in a globalizing world. It is the driving force for development and progress. In course of the last 30 years, it became an inevitable element of HE management. However, it carries along a number of risks, pitfalls, and organizational challenges. To hedge those, quality assurance (QA) is called to the stage. HEIs therefore...

  • Analysis of the Factors Affecting Static In Vitro Pepsinolysis of Food Proteins

    In this meta-analysis, we collected 58 publications spanning the last seven decades that reported static in vitro protein gastric digestion results. A number of descriptors of the pepsinolysis process were extracted, including protein type; pepsin activity and concentration; protein concentration; pH; additives; protein form (e.g., ‘native’, ‘emulsion’, ‘gel’, etc.); molecular weight of the protein; treatment; temperature; and...

    - Nature Protocols - Rok 2019

    Developing a mechanistic understanding of the impact of food structure and composition on human health has increasingly involved simulating digestion in the upper gastrointestinal tract. These simulations have used a wide range of different conditions that often have very little physiological relevance, and this impedes the meaningful comparison of results. The standardized protocol presented here is based on an international consensus...

  • Bile salts in digestion and transport of lipids
    Publikacja

    - ADVANCES IN COLLOID AND INTERFACE SCIENCE - Rok 2019

    Because of their unusual chemical structure, bile salts (BS) play a fundamental role in intestinal lipid digestion and transport. BS have a planar arrangement of hydrophobic and hydrophilic moieties, which enables the BS molecules to form peculiar self-assembled structures in aqueous solutions. This molecular arrangement also has an influence on specific interactions of BS with lipid molecules and other compounds of ingested food...

    - Journal of Functional Foods - Rok 2021

    In vitro digestion studies often use animal digestive enzyme extracts as substitutes of human gastric and pancreatic secretions. Pancreatin from porcine origin is thus commonly used to provide relevant pancreatic enzymes such as proteases, amylase and lipase. Rabbit gastric extracts (RGE) have been recently introduced to provide gastric lipase in addition to pepsin. Before preparing simulated gastric and pancreatic extracts with...

  • Importance of Conjugation of the Bile Salt on the Mechanism of Lipolysis
    Publikacja

    We aim to advance the discussion on the significance of the conjugation of bile salts (BS) in our organism. We hypothesize that conjugation influences the rate of lipolysis. Since the rate of lipolysis is a compound parameter, we compare the effect of conjugation on four surface parameters, which contribute to the rate. Since deconjugation is due to gut microbiota, we hypothesize that microbiota may affect the rate of lipolysis....

  • Importance of Bile Composition for Diagnosis of Biliary Obstructions
    Publikacja

    - MOLECULES - Rok 2021

    Determination of the cause of a biliary obstruction is often inconclusive from serum analysis alone without further clinical tests. To this end, serum markers as well as the composition of bile of 74 patients with biliary obstructions were determined to improve the diagnoses. The samples were collected from the patients during an endoscopic retrograde cholangiopancreatography (ERCP). The concentration of eight bile salts, specifically...

  • Influence of sulphanilamide in wastewater on Anammox process
    Publikacja

    - Rok 2006

    Badano wpływ krótko- oraz długookresowej ekspozycji mieszanej kultury Anammox na działanie sulfonamidu. Otrzymane wyniki potwierdziły, że sulfanilamid (SA)hamuje proces Anammox. Wyższe stężenia SA powodowały silniejszy efekt inhibicji usuwania związków azotu ze ścieków. Natomiast długookresowe testy potwierdziły hipotezę, że wydłużenie czasu ekspozycji mikroorganizmów Anammox na działanie SA skutkuje obniżeniem stopnia inhibicji...

  • Behavior of lipids in biological wastewater treatment plant processes

    Lipidy (oleje, smary, tłuszcze oraz długołańcuchowe kwasy tłuszczowe) są istotnym składnikiem ścieków. Ich ilość np. w ściekach komunalnych stanowi około 30-40% ogólnej wartości ChZT. Przemiany lipidów w procesach biologicznego oczyszczania są obiektem wielu badań, mimo to nie są do końca poznane i zrozumiane. W pracy przedstawiono przegląd literatury dotyczący przemian lipidów w trakcie tlenowego i beztlenowego oczyszczania ścieków...

  • Effect of different crystalline structures on W/O and O/W/O wax emulsion stability

    tThe possibility of emulsion stabilization using mineral and vegetable wax particles only (without sur-factant) was investigated. Mineral waxes, paraffin wax and ceresin, and a vegetable wax, carnauba wax,were used. The content of the wax particles and the water to oil proportion were found crucial for thestability of all emulsions. Some emulsions were also produced with a liquid wax (i.e. jojoba oil). Themultiple light scattering...
