In vitro selection criteria for probiotic bacteria of human origin: correlation with in vivo findings
Probiotics lactic acid bacteria
2016/6/12
The enteric flora comprises 95% of the total
number of cells in the human body and can elicit immune
responses while protecting against microbial pathogens. However,
the resident bacterial flora of...

especially in relation to cardiovascular disease and cancer.
Excentral cleavage of ß-carotene in vivo in a healthy man
ß -carotene ß -apo-carotenal humans vitamin A 14C
2008/12/12
Background:Excentral cleavage of ß-carotene to retinoids and apocarotenoids occurs in vitro and in animal models. Whether it occurs in humans is unclear.Objective:We tested the hypothesis of whe...
Antioxidant activity and hepatoprotective potential of agaro-oligosaccharides in vitro and in vivo
hepatoprotective potential Antioxidant activity
2008/4/23
Agaro-oligosaccharides derived from red seaweed polysaccharide have been reported to possess antioxidant activity. In order to assess the live protective effects of agar-oligosaccharides, we did both ...
Smoking and exposure to environmental tobacco smoke decrease some plasma antioxidants and increase γ-tocopherol in vivo after adjustment for dietary antioxidant intakes
smokers passive smokers body mass index

Free radicals in cigarette smoke may cause oxidative damage to macromolecules, contributing to cardiovascular diseases and cancer. Decreased plasma antioxidant concentrations may indicate cigarette sm...
Iron supplements inhibit zinc but not copper absorption in vivo in ileostomy subjects
Ileostomy zinc copper
2017/1/4
Iron supplements may inhibit intestinal zinc and copper uptake because these elements may compete for binding to a transporter molecule (divalent metal transporter 1) that is located on the apical sid...

Primed, constant infusion with [2H3]serine allows in vivo kinetic measurement of serine turnover, homocysteine remethylation, and transsulfuration processes in human one-carbon metabolism
Serine hydroxymethyltransferase apolipoprotein B-100 methionine homocysteine
2016/6/8
Background: One-carbon metabolism involves both mitochondrial
and cytosolic forms of folate-dependent enzymes in
mammalian cells, but few in vivo data exist to characterize the
biochemical processe...
