Microencapsulation of Oil Using Selected Soluble Fractions of Dietary Fiber as the Wall Material.

The aim of the study was to prove the usefulness of microencapsulation of oil regarding its vulnerability to oxidation caused by oxygen, temperature, and other factors. Pectin, inulin, gum arabic, and β-glucan, each of them mixed with maltodextrin, were used as wall materials and their appropriability to reduce oxidation of the core material was examined. Microcapsules were prepared by spray drying, which is the most commonly used and very effective method.

Microencapsulation of sea buckthorn oil with β-glucan from barley as coating material.

Due to large amounts of polyunsaturated fatty acids, carotenoids, polyphenols and tocopherols, sea buckthorn oil is enjoying growing popularity among consumers. To meet their expectations food producers are more and more willing to add it to products such as yogurts, juices and bread. Unfortunately due to high content of compounds sensitive to the process to which food products are subjected, the oil addition is limited.

Optimal conditions for immunohistochemical determination of the in vitro DNA synthesis labelling index with bromodeoxyuridine in head and neck cancer.

The in vitro DNA synthesis labelling index was assessed immunohistochemically in 24 freshly obtained specimens of head and neck cancer using bromodeoxyuridine (BrdUrd) as the DNA precursor to determine the influence of BrdUrd concentration on labelling index (LI). Initially, tumour fragments were incubated in varying concentrations of BrdUrd from 2 to 100 microM for 2 h, and BrdUrd was detected with an anti-BrdUrd monoclonal antibody using immunoperoxidase labelling. There was a dose-response gradient with mean LI varying from 1.

The influence of tumor stage and metastasis on the biodistribution of gallium-67 citrate in the murine Lewis lung carcinoma model.

The biodistribution of i.v. administered [67Ga]citrate was investigated in the Lewis lung carcinoma/male B6D2F1 mouse model.
