Lactose malabsorption is a common condition caused by reduced expression or activity of lactase in the small intestine. In such patients, lactose intolerance is characterized by abdominal symptoms (e.g. nausea, bloating, and pain) after ingestion of dairy products. The genetic basis of lactose malabsorption is established and several tests for this condition are available, including genetic, en...

BACKGROUND Lactose intolerance resulting in gastrointestinal symptoms is a common health concern. Diagnosis and management of this condition remain unclear. PURPOSE To assess the maximum tolerable dose of lactose and interventions for reducing symptoms of lactose intolerance among persons with lactose intolerance and malabsorption. DATA SOURCES Multiple electronic databases, including MEDLI...

We describe a MIX cascade protocol and a reputation system that together increase the reliability of a network of MIX cascades. In our protocol, MIX nodes periodically generate a communally random seed that, along with their reputations, determines cascade configuration. Nodes send test messages to monitor their cascades. Senders can also demonstrate message decryptions to convince honest casca...

Lactose in dairy systems can exist in various crystalline and non-crystalline forms. These forms affect lactose behaviour, particularly in processing and storage of low-water dairy foods. Crystalline -lactose monohydrate and anhydrous -lactose are well-known solid forms of lactose, which are relatively poorly soluble in water. Its occurrence in two anomeric forms, and -lactose, makes its solubi...

Solutions of maltodextrins (MD) with the dextrose equivalent (D.E.) 9-12 and D.E. 23-27 were mixed with lactose solutions at different ratios. Freeze-dried amorphous solids of lactose and lactose-MD were prepared from solutions containing 20% total solids. The ratios of lactose and MD were 90:10, 80:20, and 70:30 (w/w). Crystallization rate of amorphous lactose was followed from changes in wate...

It has been suggested that lactose malabsorption is an important factor in producing the diarrhoea of acute rotavirus infection. Accordingly, the lactose tolerance of gnotobiotic newborn lambs, infected with lamb rotavirus, has been investigated by clinical studies and tissue enzyme assays. Although lactase activity is low in affected areas of the small intestine, rotavirus infected lambs are n...

Skim milk of approximately 3% total protein was ultrafiltered to 16.2% protein and 4.1 % lactose, and then diafiltered to reduce lactose to 2.1% and 0.9%. Total protein con ten t was maintained at approximately 17%. A ponion of the sk im milk was condensed in a rising film evaporator to 14.7% protein and 15.7 % lactose . All concentrates were spray dried at 120 to 125 °C inlet air temperature a...

BACKGROUND symptoms attributed to the lactose intolerance are an important public health issue because of their prevalence and social relevance. Also because they may cause undue rejection of dairy products consume with potential health consequences. Transit time is a putative factor implied in the severity of symptoms associated with lactose. OBJECTIVES to elucidate the relation between oroc...
