Cryogel disks for lactase immobilization and lactose-free milk production [PDF]

, 2022
This study aims to optimize lactase immobilization onto Fe-chelated cryogel disks. p(AAm-HEMA) cryogel disks were prepared by free radical polymerization and chelated with Fe ions to prepare IMAC material.

Low Prevalence of Lactase Persistence in Bronze Age Europe Indicates Ongoing Strong Selection over the Last 3,000 Years.

Current Biology, 2020
Lactase persistence (LP), the continued expression of lactase into adulthood, is the most strongly selected single gene trait over the last 10,000 years in multiple human populations. It has been posited that the primary allele causing LP among Eurasians,

Why and when was lactase persistence selected for? Insights from Central Asian herders and ancient DNA

PLoS Biology, 2020
The genetic adaptation of humans to the consumption of milk from dairying animals is one of the most emblematic cases of recent human evolution. While the phenotypic change under selection, lactase persistence (LP), is known, the evolutionary advantage ...

Investigating thermal stability based on the structural changes of lactase enzyme by several orthogonal methods

Biotechnology Reports, 2021
Highlights • The primary and secondary structure of lactase was not changed by thermal stress.• The glycan structure of lactase showed significant alterations after heat stress.• Changes in the glycosylation structure affected physico-chemical properties

Effects of the lactase 13910 C/T and calcium-sensor receptor A986S G/T gene polymorphisms on the incidence and recurrence of colorectal cancer in Hungarian population [PDF]

, 2008
Background: Epidemiological studies suggested the chemopreventive role of higher calcium intake in colorectal carcinogenesis. We examined genetic polymorphisms that might influence calcium metabolism: lactase (LCT) gene 13910 C/T polymorphism causing ...

Lactase persistence genotypes and malaria susceptibility in Fulani of Mali

Malaria 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.

The evolution of lactase persistence

Antropologia Portuguesa, 2012
Lactase persistence has long been recognized as a striking example of human dietary adaptation to changes in food production habits. The observation that the prevalence of lactase persistence is positively correlated with the cultural history of dairying

Strain-Level Analysis of Bifidobacterium spp. from Gut Microbiomes of Adults with Differing Lactase Persistence Genotypes

mSystems, 2020
When humans domesticated animals, some adapted genetically to digest milk into adulthood (lactase persistence). The gut microbiomes of people with lactase-persistent genotypes (AA or AG) differ from those with lactase-nonpersistent genotypes (GG) by ...
