Frequency of LCT -13910C>T single nucleotide polymorphism associated with adult-type hypolactasia/lactase persistence among Brazilians of different ethnic groups [PDF]
Background Adult-type hypolactasia, the physiological decline of lactase some time after weaning, was previously associated with the LCT -13910C>T polymorphism worldwide except in Africa.

Among people of European descent, the ability to digest lactose into adulthood arose via strong positive selection of a highly advantageous allele encompassing the lactase gene. Lactose-tolerant and intolerant individuals may have different disease risks

Impact of selection and demography on the diffusion of lactase persistence. [PDF]
BACKGROUND:The lactase enzyme allows lactose digestion in fresh milk. Its activity strongly decreases after the weaning phase in most humans, but persists at a high frequency in Europe and some nomadic populations.

Levels of disaccharidases in the brush border membrane of equine small intestine [PDF]
The disaccharides, consisting of sucrose, lactose and maltose, are hydrolysed into monosaccharides (D-glucose, D-galactose and D-fructose) by intestinal brush border enzymes: sucrase, lactase and maltase.

Lactase Deficiency and Lactose Intolerance: Current Understanding and Future Directions
Introduction and purpose: Lactose, the primary carbohydrate in milk, requires the enzyme lactase for digestion. Deficiency in lactase activity leads to lactose intolerance, causing gastrointestinal symptoms.

Demonstration of lactase activity in culture medium of melon cells
Lactase activity was detected in a culture medium of the cell suspension culture of watermelon (Citrullus vulgaris L.). A simple, rapid and reproducible procedure for identification of extracellular lactase is described using callus cultures of seedlings

Admixture Correction in the Outgroup-f3 Statistic [PDF]
Genetic inheritance can be studied within a purely genetic scope. However, this eliminates part of the picture. The field of genetics is often thought of as a natural science with little in common with fields of social science. However, in human genetics

Production of HPMC-films for lactase administration [PDF]
The present work aimed to develop and characterize HPMC-films (HFs) based on hydroxypropylmethylcellulose (HPMC) with the addition of lactase for later application in the reduction of lactose in whole milk. The HFs were produced by the casting technique,

Immobilization of lactase to Perloza cellulose resins : a thesis was presented in partial fulfilment of the requirements for the degree of Master of Science in Chemistry at Massey University [PDF]
A bead cellulose matrix, Perloza, was chemically modified by two attachment chemistries to prepare inexpensive resins for immobilization of lactase. A commercial product, the base-activated matrix Eupergit C was studied for comparison.
