In-patient costs of agitation and containment in a mental health catchment area.

Background: There is a scarce number of studies on the cost of agitation and containment interventions and their results are still inconclusive. We aimed to calculate the economic consequences of agitation events in an in-patient psychiatric facility providing care for an urban catchment area.

Methods: A mixed approach combining secondary analysis of clinical databases, surveys and expert knowledge was used to model the 2013 direct costs of agitation and containment events for adult inpatients with mental disorders in an area of 640,572 adult inhabitants in South Barcelona (Spain).

Health service use and costs associated with aggressiveness or agitation and containment in adult psychiatric care: a systematic review of the evidence.

Background: Agitation and containment are frequent in psychiatric care but little is known about their costs. The aim was to evaluate the use of services and costs related to agitation and containment of adult patients admitted to a psychiatric hospital or emergency service.

Methods: Systematic searches of four electronic databases covering the period January 1998-January 2014 were conducted.

Removal of centrosomal PP1 by NIMA kinase unlocks the MPF feedback loop to promote mitotic commitment in S. pombe.

Background: Activation of the Cdk1/cyclin B complex, also known as mitosis-promoting factor (MPF), drives commitment to mitosis. Interphase MPF is inhibited through phosphorylation of Cdk1 by Wee1-related kinases. Because Cdc25 phosphatases remove this phosphate, Cdc25 activity is an essential part of the switch that drives cells into mitosis.

Schizosaccharomyces pombe protein phosphatase 1 in mitosis, endocytosis and a partnership with Wsh3/Tea4 to control polarised growth.

PP1 holoenzymes are composed of a small number of catalytic subunits and an array of regulatory, targeting, subunits. The Schizosaccharomyces pombe genome encodes two highly related catalytic subunits, Dis2 and Sds21. The gene for either protein can be individually deleted, however, simultaneous deletion of both is lethal.

Nucleocytoplasmic shuttling of the splicing factor SIPP1.

SIPP1 (splicing factor that interacts with PQBP1 and PP1) is a widely expressed protein of 70 kDa that has been implicated in pre-mRNA splicing. It interacts with protein Ser/Thr phosphatase-1 (PP1) and with the polyglutamine-tract-binding protein 1 (PQBP1), which contributes to the pathogenesis of X-linked mental retardation and neurodegenerative diseases caused by polyglutamine tract expansions. We show here that SIPP1 is a nucleocytoplasmic shuttling protein.

SIPP1, a novel pre-mRNA splicing factor and interactor of protein phosphatase-1.

We have identified a polypeptide that was already known to interact with polyglutamine-tract-binding protein (PQBP)-1/Npw38 as a novel splicing factor and interactor of protein phosphatase-1, hence the name SIPP1 for splicing factor that interacts with PQBP-1 and PP1 (protein phosphotase 1). SIPP1 was inhibitory to PP1, and its inhibitory potency was increased by phosphorylation with protein kinase CK1. Two-hybrid and co-sedimentation analysis revealed that SIPP1 has two distinct PP1-binding domains and that the binding of SIPP1 with PP1 involves a RVXF (Arg-Val-Xaa-Phe) motif, which functions as a PP1-binding sequence in most interactors of PP1.
