BACKGROUND The question of which antipsychotic drug should be preferred for the treatment of schizophrenia is controversial, and conventional pairwise meta-analyses cannot provide a hierarchy based on the randomised evidence. We aimed to integrate the available evidence to create hierarchies of the comparative efficacy, risk of all-cause discontinuation,(More)
Short-chain fatty acid irrigation has been shown to ameliorate inflammation in diversion colitis. In this study the effect of butyrate enemas was tested in 10 patients with distal ulcerative colitis who had been unresponsive to or intolerant of standard therapy for 8 weeks. They were treated for 2 weeks with sodium butyrate (100 mmol/L) and 2 weeks with(More)
Parkinson's disease (PD) is characterized by widespread alpha-synuclein pathology and neuronal loss, primarily of the nigrostriatal dopaminergic neurons. Inflammation has been implicated in PD, and alpha-synuclein can initiate microglial activation; however, the kinetics and distribution of inflammatory responses to alpha-synuclein overexpression in vivo(More)
BACKGROUND Experimental studies have indicated dietary fish oil as a protective agent in colon carcinogenesis. Prostaglandins have been suggested to be involved in this process. In the present study, the effects of fish oil on rectal cell proliferation (i.e., intermediate biomarker of cancer risk), mucosal membrane fatty acids, and prostaglandin E2 (PGE2)(More)
Identification of mutations that cause rare familial forms of Parkinson’s disease (PD) and subsequent studies of genetic risk factors for sporadic PD have led to an improved understanding of the pathological mechanisms that may cause nonfamilial PD. In particular, genetic and pathological studies strongly suggest that alpha-synuclein, albeit very rarely(More)
Although progress has been made in the symptomatic treatment of Parkinson's disease since the discovery of L-dopa in the 1960s, no neuroprotective therapy is yet available. Absence of adequate animal models of the disease that enable prediction of clinical success of potential treatments is often cited as a major impediment to progress and discourages(More)
Hemoglobin is the oxygen carrier in vertebrate blood erythrocytes. Here we report that hemoglobin chains are expressed in mammalian brain neurons and are regulated by a mitochondrial toxin. Transcriptome analyses of laser-capture microdissected nigral dopaminergic neurons in rats and striatal neurons in mice revealed the presence of hemoglobin alpha, adult(More)
Quantitative estimates of M- and L-type phosphorylase subunits in adult and developing rat tissues have been obtained by immunotitration of tissue extracts with subunit-specific antibodies. It has been shown that M-type subunits occur in all studied tissues with exception of adult liver and placenta. L-type subunits account for most of the total(More)
UNLABELLED Much evidence from distinct lines of investigation indicates the involvement of angular gyrus (AnG) in the retrieval of both episodic and semantic information, but the region's precise function and whether that function differs across episodic and semantic retrieval have yet to be determined. We used univariate and multivariate fMRI analysis(More)
