Colonic adaptation to daily lactose feeding in lactose maldigesters reduces lactose intolerance [PDF]

The American Journal of Clinical Nutrition, 1996
We conducted blinded, controlled crossover studies to determine the effect of daily lactose feeding on colonic adaptation and intolerance symptoms. The initial study with nine lactose maldigesters showed a threefold increase in fecal beta-galactosidase activity after 16 d of lactose feeding.

Regulation of metabolism in Escherichia coli during growth on mixtures of the non-glucose sugars: arabinose, lactose, and xylose

Scientific Reports, 2018
Catabolite repression refers to the process where the metabolism of one sugar represses the genes involved in metabolizing another sugar. While glucose provides the canonical example, many other sugars are also known to induce catabolite repression ...

Enzymatic Sialylation of Synthetic Multivalent Scaffolds: From 3′‐Sialyllactose Glycomacromolecules to Novel Neoglycosides

Macromolecular Bioscience, Volume 22, Issue 12, December 2022., 2022
The combination of solid phase polymer synthesis and enzymatic sialyation is used to yield multivalent stereoselective 3′‐sialyllactose‐presenting macromolecules. The one pot reaction using synthetase NmCSS and sialyltransferase PmST1 is suitable to transfer sialic acid to either glycan acceptors, such as lactose, but as shown now in this study also to

A comparison of industrial lactose obtained by roller compaction with spray dried lactose and α-lactose monohydrate using compression analysis techniques [PDF]

Journal of Excipients and Food Chemicals
The aim of this study was to develop a lactose excipient using a production-scale roller compactor suitable for use in the pharmaceutical industry. The physical properties and compression behavior of the roller compacted lactose were investigated using ...

Bistability of the lac operon during growth of Escherichia coli on lactose and lactose + glucose [PDF]

arXiv, 2007
The lac operon of Escherichia coli exhibits bistability. Early studies showed that bistability occurs during growth on TMG/succinate and lactose + glucose, but not during growth on lactose. More recent studies with lacGFP-transfected cells show bistability with TMG/succinate, but not with lactose and lactose + glucose.

Influence of Lactose on Faecal Microflora in Lactose Maldigestors [PDF]

Microbial Ecology in Health and Disease, 1993
The effects of lactose intake on the human faecal microflora and on the faecal organic acids were investigated in 24 Japanese male volunteers who took 15 g of the test sugar daily for 6 d. Twenty-two of the 24 subjects (92 per cent) were classified as lactose maldigestors by the hydrogen breath test.

Detection of Lectin Clustering in Self‐Assembled, Glycan‐Functionalized Amphiphiles by Aggregation‐Induced Emission Luminophores

Macromolecular Chemistry and Physics, Volume 224, Issue 1, January 2023., 2023
Glycan‐functionalized amphiphiles equipped with an AIE‐luminophore are attained via solid‐phase polymer synthesis and assembled into supramolecular assemblies (i.e., micelles and giant unilamellar vesicles). Driven by multivalent lectin‐carbohydrate binding, aggregation‐induced emission is then prompted or enhanced through the formation of local ...

Metallo-Dielectric Multilayer Structure for Lactose Malabsorption Diagnosis through H2 Breath Test [PDF]

arXiv, 2007
A metallo-dielectric multilayer structure is proposed as a novel approach to the analysis of lactose malabsorption. When lactose intolerance occurs, the bacterial overgrowth in the intestine causes an increased spontaneous emission of H2 in the human breath.
