Population designations in biomedical research: Limitations and perspectives

open access: yesHLA, Volume 101, Issue 1, Page 3-15, January 2023., 2023
In biomedical research, population differences are of central interest. Variations in the frequency and severity of diseases and in treatment effects among human subpopulation groups are common in many medical conditions. Unfortunately, the practices in terms of subpopulation labeling do not exhibit the level of rigor one would expect in biomedical ...

Effect of lactase on symptoms and hydrogen breath levels in lactose intolerance: A crossover placebo‐controlled study

open access: yesJGH Open, 2021
Background and Aim The absence of lactase in the intestinal villi due to mucosal injury or genetic factors causes undigested lactose to reach the colon where it is fermented.

A worldwide correlation of lactase persistence phenotype and genotypes

open access: yesBMC Evolutionary Biology, 2010
Background The ability of adult humans to digest the milk sugar lactose - lactase persistence - is a dominant Mendelian trait that has been a subject of extensive genetic, medical and evolutionary research.

New insights into the molecular basis of lactase non-persistence/persistence: a brief review.

open access: yesDrug Discoveries & Therapeutics, 2020
Lactose, a disaccharide and main carbohydrate in milk, requires hydrolysis in the intestinal tract to release its monosaccharides galactose and glucose for use as energy source by enterocytes.

Evolution of Lactase Persistence: Turbo-Charging Adaptation in Growth Under the Selective Pressure of Maternal Mortality?

open access: yesFrontiers in Physiology, 2021
The emergence of the capacity to digest milk in some populations represents a landmark in human evolution, linking genetic change with a component of niche construction, namely dairying.

Lactose digestion in humans: intestinal lactase appears to be constitutive whereas the colonic microbiome is adaptable

open access: yesAmerican Journal of Clinical Nutrition, 2019
Globally, ∼70% of adults are deficient in intestinal lactase, the enzyme required for the digestion of lactose. In these individuals, the consumption of lactose-containing milk and dairy products can lead to the development of various gastrointestinal ...

Characterization of putative mannoprotein in Kluyveromyces lactis for lactase production

open access: yesSynthetic and Systems Biotechnology, 2023
Lactase is a member of the β-galactosidase family of enzymes that can hydrolyze lactose into galactose and glucose. However, extracellular lactase production was still restricted to the process of cell lysis.

Lactase persistence genotypes and malaria susceptibility in Fulani of Mali

open access: yesMalaria Journal, 2011
Background Fulani are a widely spread African ethnic group characterized by lower susceptibility to Plasmodium falciparum, clinical malaria morbidity and higher rate of lactase persistence compared to sympatric tribes.

Lactase deficiency: latest diagnostic methods and treatment

open access: yesМедицинский совет, 2013
The article tells about latest data on etiology, pathegenesis, diagnosis and treatment of lactase deficiency in children. Feces analysis for carbohydrates for diagnosis of lactase deficiency is not recommended.
