Frequency of adult type-associated lactase persistence LCT-13910C/T genotypes in the Czech/Slav and Czech Roma/Gypsy populations

Genetics and Molecular Biology, 2017
Lactase non-persistence (leading to primary lactose intolerance) is a genetically dependent inability to digest lactose in adulthood. As part of the human adaptation to dairying, the human lactase LCT-13910C/T mutation (which propagates adult expression ...

Lactase Deficiency and Lactose Intolerance: Current Understanding and Future Directions

Journal of Education, Health and Sport
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.

Association of the Lactase Persistence Haplotype Block With Disease Risk in Populations of European Descent

Frontiers in Genetics, 2020
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

Levels of disaccharidases in the brush border membrane of equine small intestine [PDF]

Iraqi Journal of Veterinary Sciences, 2020
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.

Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

Animal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

The onset of lactase persistence in Europe

, 2013
The genomic region containing the lactase (LCT) gene shows one of the strongest signals of positive selection in Europeans, detectable using a range of approaches including haplotype length, linked microsatellite variation and population-differentiation ...

World-wide distributions of lactase persistence alleles and the complex effects of recombination and selection [PDF]

, 2017
The genetic trait of lactase persistence (LP) is associated with at least five independent functional single nucleotide variants in a regulatory region about 14 kb upstream of the lactase gene [-13910*T (rs4988235), -13907*G (rs41525747), -13915*G ...

Production of HPMC-films for lactase administration [PDF]

Anais da Academia Brasileira de Ciências, 2020
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,

Application of current enteral nutrition support recommendations to infants born less than 750 grams or less than 25 weeks' gestation: A critical review

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Clinicians face a paucity of evidence‐based recommendations for provision of enteral nutrition in infants born <750 g or <25 weeks’ gestation, termed “nano‐preterm.” Current enteral nutrition recommendations for extremely low birth weight infants may not be broadly applicable to nano‐preterm infants due to physiological and developmental ...

Demonstration of lactase activity in culture medium of melon cells

Horticultural Science, 2004
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
