Objective: To identify possible suicide risk factors in a clinical sample and suicide risk in a general population, with primary focus on mental disorders, signs, symptoms and comorbidity. Methods: In the first two studies, subjects who had been admitted to a specialised psychiatric ward after a suicide attempt were investigated. Fifteen suicide completers were compared to matched survivors in te

The rat and human recombinant soluble and membrane-bound catechol O-methyltransferase (S- and MB-COMT, respectively) were expressed using mammalian and baculovirus vectors. Low levels of rat and human S-COMT polypeptides were detected by immunoprecipitation in K-562 cell lines transfected with the S-COMT vectors. From K-562 cells transfected with the rat MB-COMT construct, both S- and MB-COMT reco

Somatic mosaicism, the presence of genetically distinct cells within an organism, has been increasingly associated with human morbidity, ranging from being a cause of rare syndromes to a risk factor for common disorders such as malignancy and cardiovascular disease. Previous studies interrogating the normal prevalence of somatic mosaicism have focused on adults. We here present an estimate of the

In traditional diffusion MRI, short pulsed field gradients (PFG) are used for the diffusion encoding. The standard Stejskal-Tanner sequence uses one single pair of such gradients, known as single-PFG (sPFG). In this work we describe how trajectories in q-space can be used for diffusion encoding. We discuss how such encoding enables the extension of the well-known scalar b-value to a tensor-valued

In order to describe a novel approach for the clinical study of metastases, we provide here age-specific incidence and survival data for cancer of unknown primary (CUP). Metastases in various organs are found at CUP diagnosis, which have implications for prognosis, and we hypothesize similar prognostic implications for metastases found at diagnosis of primary cancers. We identified 33,224 CUP pati

Elsystemet står inför en stor förändring som kommer av omställningen till ett utsläppsfritt samhälle. Elsystemet är en central del av vår samhälleliga infrastruktur och dess utveckling har till stor del styrts av politiska beslut även om marknaden fått allt större utrymme sedan 1990-talet. Stora tekniska system utvecklas alltid i samklang med samhällets institutioner där samhällets ramar och regle

The cellular source for tubular regeneration following kidney injury is a matter of dispute, with reports suggesting a stem or progenitor cells as the regeneration source while linage tracing studies in mice seemingly favor the classical theory, where regeneration is performed by randomly surviving cells. We, and others have previously described a scattered cell population localized to the tubules

Ischemic stroke is often associated with loss of cortical neurons leading to various neurological deficits. A cell replacement based on stem cell transplantation to repair the damaged brain requires the generation of specific neuronal subtypes. Recently, induced pluripotent stem cells have been used to generate various subtypes of neurons in vitro for transplantation in stroke-damaged brains. Howe

PURPOSE: In the context of oncologic therapy for children, radiation therapy is frequently indicated. This study identified the frequency of and reasons for the development of high-grade acute toxicity and possible sequelae.MATERIALS AND METHODS: Irradiated children have been prospectively documented since 2001 in the Registry for the Evaluation of Side Effects After Radiation in Childhood and Ado

This paper considers the role of digital recording methods and visualisation tools in the primary recording of archaeology at the Neolithic tell site of Çatalhöyük, Turkey. Operating within and building on Çatalhöyük Research Project's understanding of reflexive methods (Hodder 2000b, 2003; Berggren and Nilson 2014; Berggren et al. 2015) we incorporate elements of science and technology studies (P

With the advent of the Functional Mock-up Interface (FMI) standard, exchanging dynamic models between modeling and simulation tools has been greatly simplified. At the core of it, FMI is a standardized and unified model execution interface for dynamic models. FMI has gained widespread adoption among users and numerous commercial and open source tools implement support for the standard. In this art

BACKGROUND: Decreased manual dexterity is common in persons after stroke. Different measures are used to assess manual dexterity, but a lack of knowledge exists about their reliability and how they are related.OBJECTIVE: To evaluate the test-retest reliability and convergent validity of 3 manual dexterity measures after stroke.DESIGN: A test-retest design.SETTING: University Hospital.PARTICIPANTS:

BACKGROUND: Maternal prepregnancy obesity (BMI ≥30 kg/m(2)) and excessive gestational weight gain (GWG) have shown a strong positive association with a higher BMI and risk of obesity in the offspring. The aim of this study is to estimate the effect of a GWG restriction program for obese pregnant women on the children's BMI at 5 years of age and weight-for-length/height (WL/H) development from 2 mo

Apoptosis is an active process that plays a key role in many physiological and pathological conditions. One of the most important organelles involved in apoptosis regulation is the mitochondrion. An increase in intracellular Ca(2+) is a general mechanism of toxicity in neurons which occurs in response to different noxious stimuli like excitotoxicity and ischemia producing apoptotic and necrotic ce

Downstream regulatory element antagonist modulator (DREAM)/potassium channel interacting protein (KChIP3) is a multifunctional protein of the neuronal calcium sensor subfamily of Ca2+-binding proteins with specific roles in different cell compartments. In the nucleus, DREAM acts as a Ca2+-dependent transcriptional repressor, and outside the nucleus DREAM interacts with Kv4 potassium channels, regu
