BACKGROUND: Gleason grading is the standard diagnostic method for prostate cancer and is essential for determining prognosis and treatment. The dearth of expert pathologists, the inter- and intraobserver variability, as well as the labour intensity of Gleason grading all necessitate the development of a user-friendly tool for robust standardisation.OBJECTIVE: To develop an artificial intelligence

Acute myeloid leukemia (AML) is associated with poor survival, and there is a strong need to identify disease vulnerabilities that might reveal new treatment opportunities. Here, we found that Toll-like receptor 1 (TLR1) and TLR2 are upregulated on primary AML CD34+CD38-cells relative to corresponding normal bone marrow cells. Activating the TLR1/TLR2 complex by the agonist Pam3CSK4 inMLL-AF9-driv

Lung cancer accounts for 1.6 million deaths per year worldwide. The majority of patients are diagnosed at advanced stages of the disease and often present with metastasis. Thus, the 5-year survival rate of lung cancer remains around 15%. Early diagnosis of lung cancer allows for better control of the disease with 5-year survival rates up to around 70%. Chest radiography is the most common techniqu

Development of human hematopoietic stem cells and differentiation of embryonic stem (ES) cells/induced pluripotent stem (iPS) cells to hematopoietic stem cells are poorly understood. NOD (Non-obese diabetic)-derived mouse strains, such as NSG (NOD-Scid-il2Rg) or NRG (NOD-Rag1-il2Rg), are the best available models for studying the function of fetal and adult human hematopoietic cells as well as ES/

This work reports a method to select the optimal working frequency in transversal bulk resonator acoustophoretic devices by electrical impedance measurements. The impedance spectra of acoustophoretic devices are rich in spurious resonance peaks originating from different resonance modes in the system not directly related to the channel resonance, why direct measurement of the piezoelectric transdu

Objective: To investigate the effectiveness of a culturally adapted lifestyle intervention for changing dietary intake, particularly energy, fat and fibre intakes, in the intervention group (IG) compared with the control group (CG). Design: Randomised controlled trial. Setting: IG (n 50) and CG (n 46). The IG was offered seven group sessions, including one cooking class, over a period of 4 months.

Whereas the characterization of B lymphoid progenitors has been facilitated by the identification of lineage-and stage-specific surface markers, the continued identification of differentially expressed proteins increases our capacity to explore normal and malignant B cell development. To identify novel surface markers with stage-specific expression patterns, we explored the reactivity of CD19+ B c

The antibody microarrays have become widespread, but their use for quantitative analyses in clinical samples has not yet been established. We investigated an immunoassay based on nanoporous silicon antibody microarrays for quantification of total prostate-specific-antigen (PSA) in 80 clinical plasma samples, and provide quantitative data from a duplex microarray assay that simultaneously quantifie

The transcription factor STAT3 is constitutively active in several malignancies including castration-resistant prostate cancer and has been identified as a promising therapeutic target. The fungal metabolite galiellalactone, a STAT3 signaling inhibitor, inhibits the growth, both in vitro and in vivo, of prostate cancer cells expressing active STAT3 and induces apoptosis of prostate cancer stem cel

Human tumors xenografted in immunodeficient mice are crucial models in nuclear medicine to evaluate the effectiveness of candidate diagnostic and therapeutic compounds. However, little attention has been focused on the biological profile of the host model and its potential effects on the bio-distribution and tumor targeting of the tracer compound under study. We specifically investigated the dissi

Previous studies of prostate cancer (PCa) risk and anthropometrics (ie, body measurements) were based on single measurements or obtained over limited time spans.

Prostate specific antigen (PSA) is a well-established tumor marker, which is frequently employed as model biomarker to develop and evaluate emerging quantitative proteomics techniques, partially due to wide access to commercialized immunoassays serving as "gold standard". We designed a multiple reaction monitoring (MRM) assay to detect PSA proteoforms in clinical samples (n=72), utilizing specific

MicroRNAs (miRNAs) are small non-coding RNAs that post-transcriptionally regulate gene expression. There have been several reports of miRNA deregulation in prostate cancer and the biological evidence for an involvement of miRNAs in prostate tumorigenesis is increasing. In this study, we show that miR-34c is downregulated in prostate cancer (p = 0.0005) by performing qRT-PCR on 49 TURPs from prosta

Diamond-Blackfan anemia (DBA) is a congenital erythroid hypoplasia caused by haploinsufficiency of genes encoding ribosomal proteins (RPs). Perturbed ribosome biogenesis in DBA has been shown to induce a p53-mediated ribosomal stress response. However, the mechanisms of p53 activation and its relevance for the erythroid defect remain elusive. Previous studies have indicated that activation of p53

Objective: To evaluate meat intake patterns in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohorts. Design and setting: 24-Hour dietary recalls were assessed within the framework of a prospective cohort study in 27 centres across 10 European countries by means of standardised computer-assisted interviews. Subjects: In total, 22 924 women and 13 031 men aged 35-74 years.

Despite the recent success of tyrosine kinase inhibitors (TKIs) in the treatment of chronic myeloid leukemia (CML), approximately 2-17% of patients develop clonal cytogenetic changes in the Philadelphia-negative (Ph(-)) cell population. A fraction of these patients, in particular those displaying trisomy 8 or monosomy 7, are at risk of developing a myelodysplastic syndrome (MDS) or acute myeloid l

Kartlägga buskar på Öland för att rädda den biologiska mångfalden. På södra delen av Öland finns ett område som kallas Stora Alvaret som har mycket höga naturvärden. En minskning av betande djur under 1900-talet har dock gjort att den biologiska mångfalden hotas av buskar som sprider sig och utkonkurrerar andra växter. I examensarbetet Looking for shrubs in an alvar undersöker Jorun Westman metodeLoss of biodiversity is an immediate threat to the planet and if no actions are taken it is expected to accelerate. The highest species richness on smaller scale is found in semi-natural temperate grasslands, with one of the documented records from Stora Alvaret on Öland, Sweden. The area is protected under the Natura 2000-network and Länstyrelsen Kalmar are responsible for monitoring while local
