Diet Rich in Simple Sugars Promotes Pro-Inflammatory Response via Gut Microbiota Alteration and TLR4 Signaling.

Diet is a strong modifier of microbiome and mucosal microenvironment in the gut. Recently, components of western-type diets have been associated with metabolic and immune diseases. Here, we studied how high-sugar diet (HSD) consumption influences gut mucosal barrier and immune response under steady state conditions and in a mouse model of acute colitis.

Intestinal Microbiota Promotes Psoriasis-Like Skin Inflammation by Enhancing Th17 Response.

Psoriasis is a chronic inflammatory skin disease in which Th17 cells play a crucial role. Since indigenous gut microbiota influences the development and reactivity of immune cells, we analyzed the link among microbiota, T cells and the formation of psoriatic lesions in the imiquimod-induced murine model of psoriasis. To explore the role of microbiota, we induced skin inflammation in germ-free (GF), broad-spectrum antibiotic (ATB)-treated or conventional (CV) BALB/c and C57BL/6 mice.

Serum ferritin levels in subjects at high risk of atherosclerosis.

Serum ferritin levels were determined in a group of 148 subjects drawn from a community study who were found to be at high risk of atherosclerosis (evaluated on the basis of the following data: levels of non-HDL cholesterol, arterial pressure, smoking status, cardiovascular or cerebrovascular disease in a subject's history, diabetes mellitus, a positive family predisposition to, or accumulation of the above factors) and compared with the levels obtained in a control group of 148 examined age- and sex-matched subjects from the same community with non-significant risk factors. Mean serum ferritin levels were higher in the whole risk group and in the subgroups of risk men and postmenopausal women than in the corresponding controls (the whole risk group: 263.4 +/- 218.

Birth weight of neonates as an indicator of morbidity and mortality in adult age and factors which influence it.

In 28 neonates born by spontaneous delivery to healthy mothers with a normal course of gestation venous umbilical blood was examined to assess the immunoreactive insulin concentration. Moreover, the birth weight of the neonates was recorded, the weight increment of the mother during pregnancy and the body mass index at the end of gestation. By means of a questionnaire and the computer programme Progana the dietary intake of the mothers at the end of pregnancy was assessed and compared with recommended allowances.
