Aflatoxins, deoxynivalenol, ochratoxin A and zearalenone are the most important mycotoxins that everyone on its own, in groups or simultaneously contaminate cereals. The external layers of cereal grains (bran) apart from health promoting ingredients are also the most contaminated part with reference to mycotoxin's presence. Therefore, consumption of a high fiber wheat-based diet represent an increased risk to consumer's health. The objective of this study was to develop a simple and reliable high performance liquid chromatography method for the simultaneous determination of these mycotoxins in wheat bran (WB)...

Ferulic acid is a natural antioxidant found in various plants and serves as a precursor for various fine chemicals, including the flavouring agent vanillin. However, expensive extraction methods have limited the commercial application of ferulic acid, in particular for the enrichment of food substrates. A recombinant Aspergillus tubingensis ferulic acid esterase Type A (FAEA) was expressed in Aspergillus niger D15#26 and purified with anion-exchange chromatography (3487 U/mg, Km  = 0.43 mM, Kcat = 0.48/min on methyl ferulate)...

In the present study, rice bran stearin was used to improve the physical stability and encapsulation efficiency of water-in-oil (W/O) emulsions fabricated from rice bran oil and polyglycerol polyricinoleate ester (PGPR). In the absence of rice bran stearin, the emulsions were highly unstable to phase separation with an oil layer forming on their surfaces. Phase separation was delayed by increasing the PGPR concentration because this reduced the water droplet size. Phase separation could be completely inhibited by replacement of 30 to 45wt% of rice bran oil with rice bran stearin due to the formation of a semi-solid fat crystal network that prevented droplet movement...

Urticarial vasculitis (UV) is a mainly leucocytoclastic vasculitis with urticarial plaques. Treating these patients is challenging as the available treatments have poor efficacy. Oral corticosteroids are considered the first-line treatment, but H1 antihistamines, dapsone, colchicine, antimalarials, ciclosporin and antileucotrienes have all been tried also. However, because of their adverse effects and/or lack of efficacy, new agents are still needed. Omalizumab, an anti-IgE antibody, shows efficacy in chronic spontaneous urticaria, and might also be a good treatment for angio-oedema and urticarial vasculitis...
