beta-lactoglobulin (lgb) is one of the proteins in the mammals’ milk synthesized by the epithelial cells of the mammary glands and affects the quality and coagulation of the milk. the aim of this study was to determine allele frequencies in lgb gene of native and holstein cattle in kerman province using pcr-rflp method. genetic polymorphism, for 100 dna samples in the locus was determined by di...

I3C-NMR studies of modified 6-lactoglobulins, cyanylated at the single thiol group, have provided evidence to support the location of the thiol at Cys-121 [ I J and useful information about the nuclear relaxation behaviour of the thiocyanate carbons of cyanylated thiol groups in proteins [2]. The O-lactoglobulin monomer contains two tryptophan residues. Trp-19 is buried deep inside the hydropho...

The interactions of proteins during the heat treatment of whey-protein-isolate (WPI)-based oil-in-water emulsions with and without added hydroxylated lecithin were studied by examining the changes in droplet size distribution and the quantity and type of adsorbed and unadsorbed proteins. Heat treatment at 90 degrees C of WPI emulsions resulted in an increase in total adsorbed protein; unadsorbe...

The number of studies regarding the influence of genetic and environmental factors of ovine milk properties of non-dairy breeds is limited. The aim of this study was to determine the influence of breed, -lactoglobulin variants and somatic cell count on the content of the principal milk ingredients and whey protein components. The study was carried out on 60 Polish Lowland and Polish Heath ewes...

The folding of globular proteins occurs through intermediate states whose characterisation provides information about the mechanism of folding. A major class of intermediate states is the compact 'molten globule', whose characteristics have been studied intensively in those conditions in which it is stable (at acid pH, high temperatures and intermediate concentrations of strong denaturants). In...

Ex vivo digestion of proteins and fat in Red Chittagong Cattle milk from Bangladesh was carried out using human gastrointestinal enzymes. This was done to investigate the protein digestion in this bovine breed's milk with an especial focus on the degradation of the allergenic milk proteins; αs1-casein and β-lactoglobulin and also to record the generation of peptides. Lipolysis of the milk fat a...

BACKGROUND AND AIMS Patients with rheumatoid arthritis (RA) often feel there is an association between food intake and rheumatoid disease severity. To investigate a putative immunological link between gut immunity and RA, food antibodies were measured in serum and perfusion fluid from the jejunum of RA patients and healthy controls to determine the systemic and mucosal immune response. METHOD...

OBJECTIVE Whether food intake can modify the course of rheumatoid arthritis (RA) is an issue of continued scientific and public interest. However, data from controlled clinical trials are sparse. We thus decided to study the clinical effects of a vegan diet free of gluten in RA and to quantify the levels of antibodies to key food antigens not present in the vegan diet. METHODS Sixty-six patie...

Cow's milk allergy (CMA) is an immunological response to cow's milk proteins such as casein, α-lactalbumin and β lactoglobulin. The aim of this study was to determine the most common cow's milk allergenic proteins in patients with CMA and identify the most effective proteins in different allergic symptoms. Eighty seven patients (≤18 years) with allergy to cow's milk from 2006 to 2013 entered th...
