BACKGROUND Despite their beneficial effects on weight loss and blood lipids, high-protein (HP) diets have been shown to increase insulin resistance and diabetes risk, whereas high-cereal-fiber (HCF) diets have shown the opposite effects on these outcomes. OBJECTIVE We compared the effects of isoenergetic HP and HCF diets and a diet with moderate increases(More)
Among enteric bacteria, the ability to grow on N-acetyl-galactosamine (GalNAc or Aga) and on D-galactosamine (GalN or Gam) differs. Thus, strains B, C and EC3132 of Escherichia coli are Aga+ Gam+ whereas E. coli K-12 is Aga- Gam-, similarly to Klebsiella pneumoniae KAY2026, Klebsiella oxytoca M5a1 and Salmonella typhimurium LT2. The former strains carry a(More)
BACKGROUND Diets high in cereal-fiber (HCF) have been shown to improve whole-body insulin sensitivity. In search for potential mechanisms we hypothesized that a supplemented HCF-diet influences the composition of the human gut microbiota and/or biomarkers of colonic carbohydrate fermentation. METHODS We performed a randomized controlled 18-week(More)
1. Hypokinesia following immobilization stress in rats is attenuated by anti-depressant drugs used in the treatment of unipolar depression. Lithium has anti-depressant effects both clinically and in other animal models of depression, but the mechanism of its anti-depressant effect has not been elucidated. 2. To determine if lithium reverses(More)
Myo-inositol is an important precursor in cellular second-messenger synthesis. It has been reported to be reduced in the cerebrospinal fluid of depressed patients and to reverse a specific effect of Li on rat behavior when given intracerebroventricularly (i.c.v.). However, myo-inositol enters the brain poorly when given peripherally, and its effects on(More)
Human microbiota associated rats are frequently used as a model to study host microbe interactions. This study investigated the long-term stability of the bacterial community in such rats. Following the association of two strains of germ-free rats (12 male animals each) with fecal bacteria from a human donor the development of the microbiota was monitored(More)
Several features common to a Western lifestyle, including obesity and low levels of physical activity, are known risk factors for gastrointestinal cancers. There is substantial evidence suggesting that diet markedly affects the composition of the intestinal microbiota. Moreover, there is now unequivocal evidence linking dysbiosis to cancer development.(More)
Using interleukin 10-deficient (IL-10(-/-) ) and wild-type mice monoassociated with either the adherent-invasive Escherichia coli UNC or the probiotic E. coli Nissle, the effect of a mild intestinal inflammation on the bacterial proteome was studied. Within 8 weeks, IL-10(-/-) mice monoassociated with E. coli UNC exhibited an increased expression of several(More)
Host-bacteria interactions have mostly been investigated with regard to the host response or to activities of pathogenic bacteria. In contrast, we aim to identify reactions of non-pathogenic bacteria that result from their contact with host cells of the gastrointestinal tract. In a proteomic approach, the response of non-pathogenic human Escherichia coli(More)
Minocycline (MIN) HCl is a tetracycline derivative previously shown to inhibit agonist-induced accumulation of cyclic adenosine monophosphate (cAMP) in vitro and suppress motor activity and amphetamine-induced hyperactivity in rats following SC injection. The present study examined the effect of IV and intracerebral MIN on baseline activity and(More)
