Evaluation of hypoglycemic effect, safety and immunomodulation of Prevotella copri in mice.

The gut bacterium Prevotella copri (P. copri) has been shown to lower blood glucose levels in mice as well as in healthy humans, and is a promising candidate for a next generation probiotic aiming at prevention or treatment of obesity and type 2 diabetes. In this study the hypoglycemic effect of live P.

Determinants of outcome of vocational rehabilitation.

Background: Information regarding the determinants of successful vocational rehabilitation (VR) is scarce.

Objective: Investigate whether sex, duration, quality of life and financial circumstances influence the success of VR.

Methods: The study group consisted of 519 participants (293 women, 56%), who finished VR in the period 2000-2014.

Genome scan of pedigrees multiply affected with bipolar disorder provides further support for the presence of a susceptibility locus on chromosome 12q23-q24, and suggests the presence of additional loci on 1p and 1q.

Objective: To localize genes conferring susceptibility to bipolar affective disorder.

Methods: Seven families were selected on the basis of containing multiple cases of bipolar affective disorder present in three or more generations, an absence of schizophrenia and unilineal transmission. DNA samples from these families were genotyped with 365 microsatellite markers spaced at approximately 10 cM intervals across the whole genome.

Neuregulin 1 and susceptibility to schizophrenia.

The cause of schizophrenia is unknown, but it has a significant genetic component. Pharmacologic studies, studies of gene expression in man, and studies of mouse mutants suggest involvement of glutamate and dopamine neurotransmitter systems. However, so far, strong association has not been found between schizophrenia and variants of the genes encoding components of these systems.

New DNA markers with increased informativeness show diminished support for a chromosome 5q11-13 schizophrenia susceptibility locus and exclude linkage in two new cohorts of British and Icelandic families.

Genetic linkage of schizophrenia to markers at 5q11.2-13.3 had been reported previously in five Icelandic and two British families, but attempts at replication in independent samples have been unsuccessful.
