Synthetic microporous membranes with functional groups covalently attached were used to selectively separate beta-lactoglobulin, BSA, and alpha-lactalbumin from rennet whey. The selectivity and membrane performance of strong (quaternary ammonium) and weak (diethylamine) ion-exchange membranes were studied using breakthrough curves, measurement of binding capacity, and protein composition of the...

The fluorescence yield of bound retinol in human retinolbinding protein (RBP) and irs prealbumin complex (PARBP) were found to be nearly the same and to exceed that of free retinol in petroleum ether by about 9-fold. Bovine serum albumin and P-lactoglobulin also formed strongly fluorescent water-soluble complexes with retinol. The fluorescence yield of retinol complexed with bovine serum albumi...

Hypersensitivity to cow milk proteins is one of the main food allergies and affects mostly but not exclusively infants, while it may also persist through adulthood and can be very severe. Different clinical symptoms of milk allergy have been established. The diagnosis of milk allergy differs widely due to the multiplicity and degrees of symptoms, and can be achieved by skin or blood tests. Cow ...

Milk and milk derivatives are widely consumed because of their high nutritional density. Donkey products have been since ancient times. The use donkey in the human diet is gaining popularity. abundance antibacterial components protective elements sets it apart from other animals. Like milk, has low fat, lactose, casein/whey protein ratio. whey protein's anti-proliferative properties imply lung ...

In 1934 Palmer (l), in R. K. Cannan’s laboratory, succeeded in obtaining from the plasma of cow’s milk a crystalline protein with the general properties of a globulin, which was subsequently designated as /3-lactoglobulin (2). According to Palmer (1) and to Sorensen and Sgrensen (3) from 50 to 60 per cent of the whey proteins can bc obtained in the form of this globulin. Detailed physicochemica...

Background: Latex allergy is a major occupational disease with prevalence nearly 5-17% among the health care workers. Objective: To determine the prevalence of latex glove allergy and its contributing factors among operation room staff. Patients and Methods: In this study, 512 operation room staff were evaluated for latex allergy, using a complete questionnaire. Those suspected to have latex al...

cow’s milk allergy is one of the most common food allergies in childhood. beta- lactoglobulin (β-  lg) is  a dominant  allergen in  cow’s milk. hydrolysis is  known as  an effective method to reduce the allergenicity of proteins. thus, the objective of this study was to compare the allergenicity of β-lg and its hydrolysates using an animal model. twenty four balb/c mice were divided into three ...

Children with eczema and sensitization to foods are recommended skin care and, if food allergy is proven by challenge, an elimination diet. For most children the diet period is transient, but the process behind tolerance development and the influence of decreased allergen exposure is not fully known. The aim of the study was to investigate the effect of elimination diet on serum and salivary an...
