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.

Mutual Intolerance Effect in Entangled Qubit Pairs [PDF]

arXiv, 2022
Analysis of the recently proposed thought experiment with the path entangled photon pairs is extended here to spin entangled electron pairs. The detailed comparison of the two cases showed the range of distinctions and similarities in their monitoring. The general results contradict the Concurrency Rule stating that intimately linked characteristics of

Cow Milk Protein Allergy and Lactose Intolerance

Current Science, 2020
Cow (also buffalo) milk protein allergy (CMPA) and Lactose Intolerance (LI) due to ingestion of milk are global issues. CMPA could be either immunoglobulin E (IgE)-mediated or non-IgE-mediated, while LI is a non-allergic response.

Therapeutic Value of Lactobacillus gasseri 345A in Chronic Constipation

Neurogastroenterology &Motility, Volume 37, Issue 5, May 2025.
Preclinical studies show Lactobacillus gasseri to increase intestinal motility and counteract capsaicin‐stimulated transient receptor potential vanilloid 1. In a clinical trial, Lactobacillus gasseri reduced abdominal pain, along with a correlation for increased complete spontaneous bowel movements.

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.

Phenotypical Characterization of Gastroenterological and Metabolic Manifestations in Patients With Williams–Beuren Syndrome

American Journal of Medical Genetics Part A, Volume 197, Issue 6, June 2025.
ABSTRACT Gastrointestinal (GI) symptoms are common in patients with Williams–Beuren syndrome (WBS), but their prevalence and possible causes are not yet fully known. This study assessed GI symptoms' prevalence and their possible origin by performing a predefined set of tests in adult WBS patients.

MTSS2 ‐Related Disorder: Refining the Phenotype in Four New Cases and Literature Review

American Journal of Medical Genetics Part A, Volume 197, Issue 6, June 2025.
ABSTRACT MTSS2 encodes a protein highly expressed in the central nervous system, with a crucial role in neurodevelopment. The de novo recurrent variant c.2011C>T (p.Arg671Trp) was first identified in 2022 as cause of Intellectual Developmental Disorder with ocular anomalies and distinctive facial features (OMIM#620086).

Dynamics of glucose-lactose diauxic growth in E. coli [PDF]

arXiv, 2007
We present a mathematical model of glucose-lactose diauxic growth in Escherichia coli including both the postive and negative regulation mechanisms of the lactose operon as well as the inducer exclusion. To validate this model, we first calculated the time evolution of beta-galactosidase for only the lactose nutrient and compared the numerical results ...
