Lactase insufficiency: a modern concept of nutrition

open access: yesЛечащий Врач, 2023
Lactase insufficiency is widespread throughout the world. The development of clinical symptoms in lactase deficiency is due to the metabolism of lactose, which is not broken down in the small intestine and processed mainly by colon microorganisms with ...

Lactose Intolerance: Common Misunderstandings [PDF]

open access: yes, 2019
Lactose intolerance primarily refers to a syndrome having different symptoms upon the consumption of foods containing lactose. It is one of the most common form of food intolerance and occurs when lactase activity is reduced in the brush border of the ...

Alternate Day Fasting Enhances Intestinal Epithelial Function During Aging by Regulating Mitochondrial Metabolism

open access: yesAging Cell, EarlyView.
Alternate day fasting alleviates aging‐induced intestinal epithelial barrier damage by regulating mitochondrial metabolism in small intestinal stem cells. ABSTRACT With advancing age, the decline in intestinal stem cell (ISC) function can lead to a series of degenerative changes in the intestinal epithelium, a critical factor that increases the risk of

Lactase persistence and milk consumption in Europe: an interdisciplinary approach involving genetics and archaeology

open access: yesDocumenta Praehistorica, 2013
The ability to digest milk during adulthood (lactase persistence) is a genetically determined trait present only in humans. Its origin and diffusion are correlated with the development of pastoralism and the consumption of fresh milk.

Nutrient Estimation from 24-Hour Food Recalls Using Machine Learning and Database Mapping: A Case Study with Lactose. [PDF]

open access: yes, 2019
The Automated Self-Administered 24-Hour Dietary Assessment Tool (ASA24) is a free dietary recall system that outputs fewer nutrients than the Nutrition Data System for Research (NDSR).

The molecular basis of lactase persistence: Linking genetics and epigenetics

open access: yesAnnals of Human Genetics, EarlyView.
Abstract Lactase persistence (LP) — the genetic trait that determines the continued expression of the enzyme lactase into adulthood — has undergone recent, rapid positive selection since the advent of animal domestication and dairying in some human populations.

Very low frequency of the lactase persistence allele LCT-13910T in the Armenian population

open access: yesAnnals of Human Biology, 2022
Primary lactose malabsorption is characterised by a down-regulation of lactase activity after weaning and inability to digest lactose in adulthood. It has been suggested that the historical introduction of dairying led to a positive selection for lactase

Characteristics of meconium impaction/retention in newborn foals: From 2006 to 2024

open access: yesEquine Veterinary Education, EarlyView.
Summary Background Meconium impaction/retention is a significant cause of colic in foals. Historically, limitations of both medical and surgical treatment are noted. Outcomes of meconium impaction/retention have not recently been reported. Objective To describe case characteristics and outcomes in foals with meconium impaction/retention.

In Vitro Functional Analyses of Infrequent Nucleotide Variants in the Lactase Enhancer Reveal Different Molecular Routes to Increased Lactase Promoter Activity and Lactase Persistence [PDF]

open access: yes, 2016
The genetic trait that allows intestinal lactase to persist into adulthood in some 35% of humans worldwide operates at the level of transcription, the effect being caused by cis-acting nucleotide changes upstream of the lactase gene (LCT).
