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 ...

Lactose Intolerance and Symptom Pattern of Lactose Intolerance among Healthy Volunteers [PDF]

Euroasian Journal of Hepato-Gastroenterology, 2016
To see the prevalence of lactose intolerance (LI) and related symptoms following oral lactose challenge in healthy volunteers.Symptoms of abdominal pain, nausea, borborygmi, flatulence, and diarrhea were noted for 24 hours and blood glucose was estimated at 0 hour and 30 minutes after 25 gm oral lactose load to healthy volunteers. Failure to rise blood

Impact of Acute and Sub‐Acute Gluten Exposure on Gastrointestinal Symptoms and Psychological Responses in Non‐Coeliac Gluten Sensitivity: A Randomised Crossover Study

United European Gastroenterology Journal, EarlyView.
ABSTRACT Background/Aims Non‐coeliac gluten sensitivity (NCGS) is a controversial entity, characterised by symptom improvement with gluten exclusion in the absence of coeliac disease. We primarily investigated the effects of acute and sub‐acute gluten on psychological and mood profiles, with secondary outcomes examining gastrointestinal symptoms and ...

Change Intolerance in Spanning Forests [PDF]

J. Theor. Probab. 16 (2003), 47--58, 2001
Call a percolation process on edges of a graph change intolerant if the status of each edge is almost surely determined by the status of the other edges. We give necessary and sufficient conditions for change intolerance of the wired spanning forest when the underlying graph is a spherically symmetric tree.

Diets in Lactose Intolerance

Annals of Nutrition and Metabolism, 1971
Diets served in lactose intolerance were prepared hitherto by elimination of milk and milk products which is associated with a number of difficulties and dangers. The authors draw attention to the possibility to reduce these difficulties by a differentiated selection of foods as regards their different lactose and calcium content.

The molecular basis of lactase persistence: Linking genetics and epigenetics

Annals 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.

Probiotics and Lactose Intolerance [PDF]

, 2012
In normal physiological conditions lactose is hydrolyzed by lactase also known as lactasephlorizin hydrolase and under its systemic name lactosegalactosehydrolase (EC 3.2.1.108), which is a brush-border membrane bound enzyme. Glucose and galactose are taken up by the intestinal cells and transported into the bloodstream (Fig. 1). A considerable part of
