Effets d'une immunomodulation de la leptine et de la cholécystokinine chez le rat en croissance
The use of antibodies to modulate the activity of existing endocrine factors is an immunomodulation. The meal-related intestinal signal cholecystokinin (CCK) and the adipose tissue-produced leptin are known as satiety hormones. Their interaction induces long- and short-terms effects. The aim of …

Bulk segregant analysis for anther culture response and leptine content in backcross families of diploid potato
… from <I>S. phureja</I> whereas the third, leptine production (a specific glycoalkaloid known to convey resistance to the Colorado potato beetle) originated from <I>S. chacoense</I>. Using CP2, a self-incompatible F₁ hybrid originating from a cross between <I>S. chacoense</I> clone 80-1 and …

La glycémie maternelle en grossesse et la leptine dans le sang de cordon : des déterminants de l’adiposité dans l’enfance
… is associated with an increase in children’s leptinemia at age 5, whereas 1h and 2h post-75g glycaemia in the 2nd trimester is positively associated with the total body fat percentage obtained by DXA (imaging technique) at 5 years of age. These associations are independent of pre-pregnancy …

Molecular marker analysis of a segregating monoploid potato family
… The donor plants used were hybrids between high leptine producing selections of Solanum chacoense Bitt. and anther culture responsive selections of Solanum phureja Juz. et Buk. Several steps of the anther culture process were studied. The results indicated that genotype remains the main factor …

Protoplast Fusion for the Production of Intermonoploid Somatic Hybrids in Cultivated Potato
… hybrid between S. chacoense and S. phureja. The leptine acetylleptinidine (ALD) is produced only by some accessions of S. chacoense Bitt. and provides resistance to feeding by the Colorado potato beetle (Leptinotarsa decemlineata Say) when present in sufficient concentrations. The somatic hybrids …

Derivation of interspecific Solanum hybrid genotypes with resistance to Colorado potato beetle (Leptinotarsa decemlineata Say)
… Chc families, regardless of selection for leptine glycolakaloids, suffered the least CPB damage and phu parental clones and hybrid families suffered the most.

Biosynthesis of Steroidal Glycoakaloids in Solanum chacoense Bitter
… fully expanded, and old senescing leaves where leptine and leptinines tend to dominate, α-solanine and α-chaconine together accounted for only 8 to 15%, 7 to 15%, and 8 to 45%, respectively. Plant organs that showed the highest biosynthetic activity for SGA production also had high levels of …

Die Veränderung neuroendokrinologischer Parameter und neuropsychologischer Funktionen bei adoleszenten Patientinnen mit Anorexia nervosa vor und nach Gewichtsrehabilitation im Vergleich zu gesunden Kontrollprobandinnen
The present study investigates a possible correlation between neuroendocrinological parameters and neuropsychological functions in adolescent patients with anorexia nervosa before and after weight recovery. Studies with adult patients suffering from eating disorder point to an impairment in …

Differentielle Genexpression in der Insulinoma-Zelllinie RINm5F nach Stimulation mit Leptin
Leptin, a cytokine secreted by the white adipose tissue, decreases food intake via hypothalamic pathways and is a major regulator of energy homoestasis. Leptin has also important peripheral effects, such as the attenuation of insulin secre-tion from pancreatic islets. Leptin signals through the …

Regulation der Genexpression und Promotoraktivität von RGS4 durch Leptin
Produced by white adipose tissue, leptin regulates bodyweight by reducing food intake and energy expenditure. Leptin exerts its main effects on the hypothalamus but also acts on peripheral cell types like pancreatic b-cells, where it inhibits insulin secretion. The leptin receptor (LepRb) belongs …
