Detection of left bundle branch block and obstructive coronary artery disease from myocardial perfusion scintigraphy using deep neural networks

Myocardial perfusion scintigraphy, which is a non-invasive imaging technique, is one of the most common cardiological examinations performed today, and is used for diagnosis of coronary artery disease. Currently the analysis is performed visually by physicians, but this is both a very time consuming and a subjective approach. These are two of the motivations for why an automatic tool to support th

A comparison of rule-based and centroid single-sample multiclass predictors for transcriptomic classification

MOTIVATION: Gene expression-based multiclass prediction, such as tumor subtyping, is a non-trivial bioinformatic problem. Most classifier methods operate by comparing expression levels relative to other samples. Methods that base predictions on the expression pattern within a sample have been proposed as an alternative. As these methods are invariant to the cohort composition and can be applied to

Developing a methodology to balance benefit-sharing : application in the context of biodiversity beyond national jurisdiction

The effectiveness and success of benefit-sharing measures to date, particularly in contributing towards the conservation and sustainable use of biodiversity, has been questionable. This is likely related to the degree of beneficial impacts versus burden on the users and regulatory authorities in terms of administrative complexities. It is, therefore, timely to reconsider which forms of benefit-sharin

Technological readiness and implementation of genomic-driven precision medicine for complex diseases

The fields of human genetics and genomics have generated considerable knowledge about the mechanistic basis of many diseases. Genomic approaches to diagnosis, prognostication, prevention and treatment – genomic-driven precision medicine (GDPM) – may help optimize medical practice. Here, we provide a comprehensive review of GDPM of complex diseases across major medical specialties. We focus on tech

Transepithelial exit of leucocytes: inflicting, reflecting or resolving airway inflammation?

The passage of infiltrated tissue granulocytes across airway epithelium into airway lumen is generally considered to be a pathogenic process in asthma and chronic obstructive pulmonary disease (COPD). An alternative hypothesis is proposed here-namely that the transepithelial egression of infiltrated leucocytes acts to rid diseased airway tissues of proinflammatory cells efficiently and non-injurio

Injuries in STS travel – a multi methodology approach to estimate incidence and societal costs

Objective: Previous research has shown that elderly and disabled travelers using Special Transportation Services (STS) are injured without being involved in a vehicle crash. In order to estimate the true costs for these vehicle-related injuries, the focus needs to be adjusted towards an incident/traveler-oriented perspective. The aim of the project was thus to utilize such a perspective, in order

Geographical variation in incidence of prostate cancer in Sweden - Survey from the National Prostate Cancer Register

Objective. To investigate the geographical variation in prostate cancer incidence in Sweden, in particular the incidences of screening-detected tumours and curative treatment of prostate cancer. Material and methods. Data were retrieved from the National Prostate Cancer Register of Sweden for all cases of prostate cancer diagnosed in the year 2000-01. There were a total of 14 376 cases of prostate

Freezing of Gait Questionnaire: validity and reliability of the Swedish version.

Background - Patient-reported assessments of freezing of gait (FOG) in Parkinson's disease (PD), such as the FOG questionnaire (FOGQ), are needed because FOG is difficult to assess objectively. However, the measurement properties of the FOGQ have been sparsely assessed. Aim - To assess the measurement properties of the Swedish FOGQ, and to explore relationships between FOGQ scores and other aspect

Asymtomatic Bacteriuria as a Model to Study the Coevolution of Hosts and Bacteria.

During asymptomatic bacteriuria (ABU), bacteria colonize the urinary tract for extended periods of time without causing symptoms of urinary tract infection. Previous studies indicate that many Escherichia coli (E. coli) strains that cause ABU have evolved from uropathogenic E. coli (UPEC) by reductive evolution and loss of the ability to express functional virulence factors. For instance, the prot

The impact of genetic, environmental and life-style factors on male reproductive function

Recent studies have indicated a decline in sperm number in the western world during the past 50 years, sperm concentration changing from 113 to 66 millions per mL. Furthermore, significant geographical differences in male reproductive function have been observed. In Finland, the sperm concentration was found to be substantially higher than in Denmark. In parallel, the incidence of testicular cance

Central projections of the sensory innervation of the rat middle meningeal artery.

Headaches, especially migraine, involve not only pain but also aspects such as vasodilation of cranial vessels and sensitization of nerve endings, processes dependent on and connected to the central nervous system. To understand pathogenic mechanisms of headache, it is important to elucidate the central projections of sensory nerves that innervate cranial vessels, of which the middle meningeal art

RIFM fragrance ingredient safety assessment, 3,4,4a,5,8,8a(Or 3,4,4a,7,8,8a)-hexahydro-3,3,6,7-tetramethyl-1H-2-benzopyran, CAS Registry Number 72429-08-4

The existing information supports the use of this material as described in this safety assessment. 3,4,4a,5,8,8a (Or 3,4,4a,7,8,8a)-Hexahydro-3,3,6,7-tetramethyl-1H-2-benzopyran was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that 3,4,4a, 5,8,8a (Or 3

Relating homology between the Epstein-Barr virus BOLF1 molecule and HLA-DQw8 β chain to recent onset Type 1 (insulin-dependent) diabetes mellitus

A role for the Epstein-Barr virus in initiating Type 1 (insulin-dependent) diabetes mellitus has been proposed since Epstein-Barr virus BOLF1(497-513) AVTPL RIFIVP PAAEY has an 11 amino acid identity with HLA-DQw8 β (49-60) AVTPL GPPAAEY. Rabbit antisera to the BOLF1 (496-515) peptide crossreacted with the homologous DQw8 β (44-63) peptide but not with the related DQw7 β(44-63) peptide, which diff

Comparison of Navigation-Related Brain Regions in Migratory versus Non-Migratory Noctuid Moths

Brain structure and function are tightly correlated across all animals. While these relations are ultimately manifestations of differently wired neurons, many changes in neural circuit architecture lead to larger-scale alterations visible already at the level of brain regions. Locating such differences has served as a beacon for identifying brain areas that are strongly associated with the ecologi

Antibiotic susceptibility patterns and clones of Pseudomonas aeruginosa in Swedish ICUs

Pseudomonas aeruginosa is 1 of the bacteria most adaptive to anti-bacterial treatment. Previous studies have shown nosocomial spread and transmission of clonal strains of P. aeruginosa in European hospitals. In this study we investigated antibiotic susceptibility and clonality in 101 P. aeruginosa isolates from 88 patients admitted to 8 Swedish ICUs during 2002. We also compared phenotypes and gen

Subtype and cell type specific expression of lncRNAs provide insight into breast cancer

Long non-coding RNAs (lncRNAs) are involved in breast cancer pathogenesis through chromatin remodeling, transcriptional and post-transcriptional gene regulation. We report robust associations between lncRNA expression and breast cancer clinicopathological features in two population-based cohorts: SCAN-B and TCGA. Using co-expression analysis of lncRNAs with protein coding genes, we discovered thre
