In this study, we first reconstructed a pathway of 138 myelin-related genes, all involved in myelin structure, composition, development or maintenance. Then we performed a two-stage association analysis on these 138 genes Combretastatin A4 solubility dmso using 771 single nucleotide polymorphisms (SNPs). Analysis of our data from

310 cases vs 880 controls demonstrated association of 10 SNPs from six genes. Specifically, we observed highly significant P-values for association in PIK4CA (observed P = 6.1 x 10(-6)). These findings remained significant after Bonferroni correction for 771 tests. The PIK4CA gene is located in the chromosome 22q11 deletion syndrome region, which is of particular interest because it has been implicated in schizophrenia. We also report weak association of SNPs in PIK3C2G, FGF1, FGFR1, ARHGEF10 and PSAP (observed P <= 0.01). Our approach-of screening genes involved in a particular pathway for association-resulted in identification of several, mostly novel, genes associated with the risk of developing schizophrenia in the Dutch population.”
“Background: There is growing recognition of a syndrome of disturbed grief referred to as check details prolonged grief disorder (PGD). PGD is mostly studied in adults, but clinically significant PGD symptoms have also

been observed in children and adolescents. Yet, to date no effective treatment for childhood PGD exists. The aims of this study are: (1) to investigate the effectiveness of

Grief-Help, a nine-session cognitive-behavioural treatment for childhood PGD, combined with five sessions of parental counselling, immediately after the treatment and at three, six and twelve months follow-up; (2) to examine STAT inhibitor tentative mediators of the effects of Grief-Help, (i.e., maladaptive cognitions and behaviours and positive parenting), and (3) to determine whether demographic variables, child personality, as well as symptoms of PGD, anxiety, and depression in parents moderate the treatment effectiveness.\n\nMethods/Design: We will conduct a Randomised Controlled Trial (RCT) in which 160 children and adolescents aged 8-18 years are randomly allocated to cognitive behavioural Grief-Help or to a supportive counselling intervention; both treatments are combined with five sessions of parental counselling. We will recruit participants from clinics for mental health in the Netherlands. The primary outcome measure will be the severity of Prolonged Grief Disorder symptoms according to the Inventory of Prolonged Grief for Children (IPG-C). Secondary outcomes will include PTSD, depression and parent-rated internalizing and externalizing problems. Mediators like positive parenting and maladaptive cognitions and behaviours will be identified. We will also examine possible moderators including demographic variables (e. g.
