Teollisuusalueesta kulttuurin keskukseksi:Oulun Pikisaaren muuttuva kulttuuriperintö ja sen merkitys
TiivistelmĂ€. TĂ€mĂ€n tutkielman aiheena on tarkastella kriittisen kulttuuriperintötukimuksen nĂ€kökulmasta sitĂ€, miten uutta kulttuuriperintöÀ valitaan, tuotetaan ja miten sitĂ€ kĂ€ytetÀÀn. Työn viitekehyksen nĂ€kökulmasta kulttuuriperintö ei ole varsinaisesti valmiina olemassa, vaan sitĂ€ syntyy, kun jokin menneisyyden jĂ€lki pÀÀtetÀÀn valita perinnöksi ja tĂ€hĂ€n menneisyyden jĂ€lkeen liitetÀÀn historialla vahvistettua, symbolista arvoa. TĂ€ssĂ€ työssĂ€ keskitytÀÀn tarkastelemaan erityisesti teollista kulttuuriperintöÀ tapaustutkimuksen kautta. Tapaustutkimuksessa yhden tai useamman âtapauksenâ avulla on mahdollista selvittÀÀ alueellisia prosesseja, mutta tarkastella myös laajemmin tutkimuksenkohteena olevaa ilmiötĂ€. Työn tapaustutkimuksen kohteena on Oulun Pikisaari, jossa on ollut teollista toimintaa 1600-luvun pikiruukista lĂ€htien aina 1970-luvulla loppuneeseen konepajateollisuuteen asti.
TyössÀ tarkasteltiin Pikisaaren muuttumista teollisuuden alueesta yhdeksi Oulun arvostetuimmaksi asuinalueeksi sekÀ alueen maisemmallista muutosta. NykypÀivÀnÀ tunnettu Pikisaari on alunperin koostunut kolmesta eri saaresta, jotka ovat yhdistyneet sekÀ maankohoamisen myötÀ, mutta myös ihmisen toiminnan vaikutuksesta, kun saarien vÀliÀ on tÀytetty. Aineistona tÀhÀn tarkasteluun kÀytettiin historiallisia asemakaavoja, peruskarttoja sekÀ ilmakuvia. TÀmÀn lisÀksi työssÀ on kÀytetty kirjallisuuslÀhteitÀ sekÀ Pikisaaresta tehtyjÀ kÀyttösuunnitelmia. TyössÀ tarkasteltiin myös sitÀ, miten Pikisaaren ja sen kulttuuriperintöön liitettyjÀ merkityksiÀ siirretÀÀn eteenpÀin ja miten saarta hyödynnetÀÀn alueen sekÀ koko Oulun imagoresurssina. NÀitÀ asioita tarkasteltiin erilaisten tekstiaineistojen, kuten markkinointitekstien sekÀ alueelta löytyvien infokylttien perusteella.
Työn tuloksina voidaan todeta, ettÀ Pikisaaren maisemallinen biografia on muuttunut suuresti aikojen saatossa. LÀhes puuttomien saarien maisemaan on teollisuusaikana piirtynyt teollisuuslaitosten korkeat piiput sekÀ sahan lautatarhat. Teollisuuden hiipuessa aluetta alettiin tarkoituksella vehreyttÀÀmÀÀn. Viimeisen teollisuuslaitoksen lopettaessa toimintansa 1970-luvulla, sekÀ alueen ettÀ vanhojen teollisuusrakennusten ja niihin liittyneiden asuinrakennusten kÀyttö piti mÀÀritellÀ uudelleen. Asuinrakennuksia alettiin vuokraamaan erityisesti kÀsityölÀisille ja taiteilijoille asuin- ja työtiloiksi, koska saaresta oli tarkoitus kehittÀÀ kulttuurialue. Vanhat teollisuusrakennukset saneerattiin myös asuinkÀyttöön tai ateljee tiloiksi.
Pikisaaren nykyistÀ kulttuuriperintöÀ voi kuvailla monipuoliseksi, sen muodostuessa saaren historiasta, teollisuuden jÀljistÀ sekÀ nykypÀivÀn kulttuurista, mitÀ saarella tuotetaan. Menneisyyden fyysisten jÀÀnteiden lisÀksi alueen kulttuuriperintöön liitetÀÀn diskursiivisesti tuotettuja merkityksiÀ ja arvoja, joita hyödynnetÀÀn alueen ja Oulun imagon luomisessa sekÀ matkailumarkkinoinnissa. Pikisaaren ja muiden kulttuurihistoriallisesti arvokkaiden alueiden kehittÀmisessÀ tulisi tulevaisuudessa huomioida entistÀ paremmin paikallisten asukkaiden alueisiin liittyvÀt arvot ja merkitykset. KulttuuriperinnöllÀ voi olla suurikin merkitys esimerkiksi ihmisten hyvinvointiin ja alueiden viihtyvyyteen
Lymphatic endothelium stimulates melanoma metastasis and invasion via MMP14-dependent Notch3 and b1-integrin activation
Lymphatic invasion and lymph node metastasis correlate with poor clinical outcome in melanoma. However, the mechanisms of lymphatic dissemination in distant metastasis remain incompletely understood. We show here that exposure of expansively growing human WM852 melanoma cells, but not singly invasive Bowes cells, to lymphatic endothelial cells (LEC) in 3D co-culture facilitates melanoma distant organ metastasis in mice. To dissect the underlying molecular mechanisms, we established LEC co-cultures with different melanoma cells originating from primary tumors or metastases. Notably, the expansively growing metastatic melanoma cells adopted an invasively sprouting phenotype in 3D matrix that was dependent on MMP14, Notch3 and ÎČ1-integrin. Unexpectedly, MMP14 was necessary for LEC-induced Notch3 induction and coincident ÎČ1-integrin activation. Moreover, MMP14 and Notch3 were required for LEC-mediated metastasis of zebrafish xenografts. This study uncovers a unique mechanism whereby LEC contact promotes melanoma metastasis by inducing a reversible switch from 3D growth to invasively sprouting cell phenotype

Prevalence of psychosis in black ethnic minorities in Britain: analysis based on three national surveys
Purpose
A considerable excess of psychosis in black ethnic minorities is apparent from clinical studies, in Britain, as in other developed economies with white majority populations. This excess is not so marked in population surveys. Equitable health service provision should be informed by the best estimates of the excess. We used national survey data to establish the difference in the prevalence of psychosis between black ethnic groups and the white majority in the British general population.
Methods
Analysis of the combined datasets (N = 26,091) from the British national mental health surveys of 1993, 2000 and 2007. Cases of psychosis were determined either by the use of the Schedules for Clinical Assessment in Neuropsychiatry (SCAN), or from a combination of screening items. We controlled for sex, age, social class, unemployment, design features and other putative confounders, using a Disease Risk Score.
Results
People from black ethnic minorities had an excess prevalence rate of psychosis compared with the white majority population. The OR, weighted for study design and response rate, was 2.72 (95 % CI 1.3â5.6, p = 0.002). This was marginally increased after controlling for potential confounders (OR = 2.90, 95 % CI 1.4â6.2, p = 0.006).
Conclusions
The excess of psychosis in black ethnic minority groups was similar to that in two previous British community surveys, and less than that based on clinical studies. Even so it confirms a considerable need for increased mental health service resources in areas with high proportions of black ethnic minority inhabitants
ASIC-E4: Interplay of Beta-Amyloid, Synaptic Density and Neuroinflammation in Cognitively Normal Volunteers With Three Levels of Genetic Risk for Late-Onset Alzheimer's Disease â Study Protocol and Baseline Characteristics
Background: Detailed characterization of early pathophysiological changes in preclinical Alzheimer's disease (AD) is necessary to enable development of correctly targeted and timed disease-modifying treatments. ASIC-E4 study (âBeta-Amyloid, Synaptic loss, Inflammation and Cognition in healthy APOE Δ4 carriersâ) combines state-of-the-art neuroimaging and fluid-based biomarker measurements to study the early interplay of three key pathological features of AD, i.e., beta-amyloid (AÎČ) deposition, neuroinflammation and synaptic dysfunction and loss in cognitively normal volunteers with three different levels of genetic (APOE-related) risk for late-onset AD. Objective: Here, our objective is to describe the study design, used protocols and baseline demographics of the ASIC-E4 study. Methods/Design: ASIC-E4 is a prospective observational multimodal imaging study performed in Turku PET Centre in collaboration with University of Gothenburg. Cognitively normal 60â75-year-old-individuals with known APOE Δ4/Δ4 genotype were recruited via local Auria Biobank (Turku, Finland). Recruitment of the project has been completed in July 2020 and 63 individuals were enrolled to three study groups (Group 1: APOE Δ4/Δ4, N = 19; Group 2: APOE Δ4/Δ3, N = 22; Group 3: APOE Δ3/Δ3, N = 22). At baseline, all participants will undergo positron emission tomography imaging with tracers targeted against AÎČ deposition (11C-PIB), activated glia (11C-PK11195) and synaptic vesicle glycoprotein 2A (11C-UCB-J), two brain magnetic resonance imaging scans, and extensive cognitive testing. In addition, blood samples are collected for various laboratory measurements and blood biomarker analysis and cerebrospinal fluid samples are collected from a subset of participants based on additional voluntary informed consent. To evaluate the predictive value of the early neuroimaging findings, neuropsychological evaluation and blood biomarker measurements will be repeated after a 4-year follow-up period. Discussion: Results of the ASIC-E4 project will bridge the gap related to limited knowledge of the synaptic and inflammatory changes and their association with each other and AÎČ in âat-riskâ individuals. Thorough in vivo characterization of the biomarker profiles in this population will produce valuable information for diagnostic purposes and future drug development, where the field has already started to look beyond AÎČ
Classification of bipolar disorder in psychiatric hospital. a prospective cohort study
<p>Abstract</p> <p>Background</p> <p>This study has explored the classification of bipolar disorder in psychiatric hospital. A review of the literature reveals that there is a need for studies using stringent methodological approaches.</p> <p>Methods</p> <p>480 first-time admitted patients to psychiatric hospital were found eligible and 271 of these gave written informed consent. The study sample was comprised of 250 patients (52%) with hospital diagnoses. For the study, expert diagnoses were given on the basis of a structured diagnostic interview (M.I.N.I.PLUS) and retrospective review of patient records.</p> <p>Results</p> <p>Agreement between the expert's and the clinicians' diagnoses was estimated using Cohen's kappa statistics. 76% of the primary diagnoses given by the expert were in the affective spectrum. Agreement concerning these disorders was moderate (kappa ranging from 0.41 to 0.47). Of 58 patients with bipolar disorder, only 17 received this diagnosis in the clinic. Almost all patients with a current manic episode were classified as currently manic by the clinicians. Forty percent diagnosed as bipolar by the expert, received a diagnosis of unipolar depression by the clinician. Fifteen patients (26%) were not given a diagnosis of affective disorder at all.</p> <p>Conclusions</p> <p>Our results indicate a considerable misclassification of bipolar disorder in psychiatric hospital, mainly in patients currently depressed. The importance of correctly diagnosing bipolar disorder should be emphasized both for clinical, administrative and research purposes. The findings questions the validity of psychiatric case registers. There are potential benefits in structuring the diagnostic process better in the clinic.</p
Genome-wide meta-analysis identifies six novel loci associated with habitual coffee consumption.
Coffee, a major dietary source of caffeine, is among the most widely consumed beverages in the world and has received considerable attention regarding health risks and benefits. We conducted a genome-wide (GW) meta-analysis of predominately regular-type coffee consumption (cups per day) among up to 91â462 coffee consumers of European ancestry with top single-nucleotide polymorphisms (SNPs) followed-up in ~30â062 and 7964 coffee consumers of European and African-American ancestry, respectively. Studies from both stages were combined in a trans-ethnic meta-analysis. Confirmed loci were examined for putative functional and biological relevance. Eight loci, including six novel loci, met GW significance (log10Bayes factor (BF)>5.64) with per-allele effect sizes of 0.03-0.14 cups per day. Six are located in or near genes potentially involved in pharmacokinetics (ABCG2, AHR, POR and CYP1A2) and pharmacodynamics (BDNF and SLC6A4) of caffeine. Two map to GCKR and MLXIPL genes related to metabolic traits but lacking known roles in coffee consumption. Enhancer and promoter histone marks populate the regions of many confirmed loci and several potential regulatory SNPs are highly correlated with the lead SNP of each. SNP alleles near GCKR, MLXIPL, BDNF and CYP1A2 that were associated with higher coffee consumption have previously been associated with smoking initiation, higher adiposity and fasting insulin and glucose but lower blood pressure and favorable lipid, inflammatory and liver enzyme profiles (P<5 Ă 10-8).Our genetic findings among European and African-American adults reinforce the role of caffeine in mediating habitual coffee consumption and may point to molecular mechanisms underlying inter-individual variability in pharmacological and health effects of coffee

Gene Ă dietary pattern interactions in obesity: analysis of up to 68 317 adults of European ancestry
Obesity is highly heritable. Genetic variants showing robust associations with obesity traits have been identified through genome-wide association studies. We investigated whether a composite score representing healthy diet modifies associations of these variants with obesity traits. Totally, 32 body mass index (BMI)- and 14 waistâhip ratio (WHR)-associated single nucleotide polymorphisms were genotyped, and genetic risk scores (GRS) were calculated in 18 cohorts of European ancestry (n = 68 317). Diet score was calculated based on self-reported intakes of whole grains, fish, fruits, vegetables, nuts/seeds (favorable) and red/processed meats, sweets, sugar-sweetened beverages and fried potatoes (unfavorable). Multivariable adjusted, linear regression within each cohort followed by inverse variance-weighted, fixed-effects meta-analysis was used to characterize: (a) associations of each GRS with BMI and BMI-adjusted WHR and (b) diet score modification of genetic associations with BMI and BMI-adjusted WHR. Nominally significant interactions (P = 0.006â0.04) were observed between the diet score and WHR-GRS (but not BMI-GRS), two WHR loci (GRB14 rs10195252; LYPLAL1 rs4846567) and two BMI loci (LRRN6C rs10968576; MTIF3 rs4771122), for the respective BMI-adjusted WHR or BMI outcomes. Although the magnitudes of these select interactions were small, our data indicated that associations between genetic predisposition and obesity traits were stronger with a healthier diet. Our findings generate interesting hypotheses; however, experimental and functional studies are needed to determine their clinical relevance
