Comparison of Quick Lactose Intolerance Test in duodenal biopsies of dyspeptic patients with single nucleotide polymorphism LCT-13910C>T associated with primary hypolactasia/lactase-persistence [PDF]

Acta Cirúrgica Brasileira, 2013
PURPOSE: To analyze the usefulness of Quick Lactose Intolerance Test in relation to the genetic test based on LCT-13910C>T genotypes, previously validated for clinical practice, for primary hypolactasia/lactase-persistence diagnosis.

Culture Optimization of the IPEC–J2 Piglet Jejunum Cell Line for Applications in Infant Nutrition Research

Molecular Nutrition &Food Research, Volume 70, Issue 12, 28 June 2026.
IPEC–J2 cell line is derived from piglet jejunal cells. Four different culture media were assessed for their ability to support IPEC‐J2 differentiation into an in vitro gut barrier. PS10 media proved most successful. Once differentiated with PS10, the IPEC‐J2 barrier was sufficiently robust for treatment with digested infant food. This demonstrates the

Table_3_Tracing the Distribution of European Lactase Persistence Genotypes Along the Americas.XLSX

, 2021
In adulthood, the ability to digest lactose, the main sugar present in milk of mammals, is a phenotype (lactase persistence) observed in historically herder populations, mainly Northern Europeans, Eastern Africans, and Middle Eastern nomads.

Lactase Persistence Variants in Arabia and in the African Arabs

Human Biology, 2014
Lactase persistence (LP), the state enabling the digestion of milk sugar in adulthood, occurs only in some human populations. The convergent and independent origin of this physiological ability in Europe and Africa is linked with animal domestication that either had started in both places independently or had spread from the Near East by acculturation.

High prevalence of lactase non-persistence among indigenous nomadic Nenets, north-west Russia [PDF]

International Journal of Circumpolar Health, 2012
Objectives. The frequency of adult-type hypolactasia (lactase non-persistence) varies widely among different ethnic groups. The cultural historical hypothesis assumes a link between the occurrence of hypolactasia and the distribution of dairy farming ...

Biocultural Approaches in the Society for the Anthropology of Food and Nutrition: A Reflection on 50 Years

Culture, Agriculture, Food and Environment, Volume 48, Issue 1, June 2026.
ABSTRACT On the occasion of SAFN's 50th anniversary I reflect on the development of biocultural and human evolutionary approaches to human diet and nutrition. I maintain that SAFN and its predecessors the Committee (1974–1987) and then Council on Nutritional Anthropology (1987–2004) have modeled, fostered, and advanced biocultural work in anthropology ...

Lactase non-persistence and milk consumption in Estonia

World Journal of Gastroenterology, 2006
To define the frequency of the C/T-13910 variant associated with lactase persistence/non-persistence trait and to analyze the milk consumption of lactase non-persistent subjects in Estonia.We genotyped 355 Estonians by polymerase chain reaction and direct sequencing.

Lactase restriction and lactase persistence: a study of sri lankans and a paediatric population [PDF]

, 1990
Lactase is an enzyme, located on the small intestinal brush border, that hydrolyses the disaccharide lactose into its monosaccharides glucose and galactose, which are then absorbed.

Beyond Malabsorption: The Need for Symptom‐Based Assessment in Suspected Lactose Intolerance. Lessons From a Test‐Specific Symptom Assessment

Neurogastroenterology &Motility, Volume 38, Issue 6, June 2026.
Breath test–proven malabsorption does not reliably predict symptoms. Many patients without malabsorption still develop significant symptoms. Symptoms after lactose ingestion are linked to fructose sensitivity and functional GI disorders. Validated, test‐specific symptom assessment is required to identify patients who may benefit from treatment ...
