Cerebrospinal fluid levels of neurogranin in Parkinsonian disorders

Background: CSF concentration of neurogranin has been suggested as a biomarker for synapse dysfunction. Objectives: To investigate CSF neurogranin in parkinsonian disorders compared to controls and Alzheimer's disease and the possible correlations between neurogranin and cognitive and motor impairment. Methods: We included 157 patients with PD, 29 with PD with dementia, 11 with dementia with Lewy

Paving the way for transparency : How eHealth technology can change boundaries in healthcare

Den digitalisering som för närvarande äger rum inom hälso- och sjukvårdssektorn ställer både nya krav och öppnar för nya möjligheter för enskilda medborgare, vårdpersonal samt olika aktörer i samhället. I många av de e-hälsolösningar som utvecklas finns bakomliggande tankar om ökad egenmakt (empowerment) för patienten genom att denne skall få ökad kontroll över sin egen hälsa och den information sThe digitalization that currently is taking place in healthcare raises questions about how this development, with visions of more patient participation and patient empowerment, changes this sector and what role eHealth can play in these changes. The term civic health technologies (Invånartjänster) is used in Sweden to describe eHealth in the healthcare sector that is developed and deployed by the

Persistent whole day meal effects of three dipeptidyl peptidase-4 inhibitors on glycaemia and hormonal responses in metformin-treated type 2 diabetes

Aim: Dipeptidyl peptidase-4 (DPP-4) inhibition has effects on both fasting and postprandial glucose. However, the extent of this effect over the whole day and whether different DPP-4 inhibitors have the same effects have not been established. We therefore explored the whole day effects of three different DPP-4 inhibitors versus placebo on glucose, islet and incretin hormones after ingestion of bre

Gender differences in allocation of attention and read time in an educational history game

Previous research has shown that female students sometimes benefit more than males when it comes to interacting with pedagogical agents. In our analysis we examined students' tendency to attend to and read feedback text that were visually signalled by a teachable agent (TA), or by an arrow (AR), or non-signalled in a control condition (CN). The results indicate that male learners may benefit from

In Search of the jüdische Typus : A Proposed Benchmark to Test the Genetic Basis of Jewishness Challenges Notions of "Jewish Biomarkers"

The debate as to whether Jewishness is a biological trait inherent from an "authentic" "Jewish type" (jüdische Typus) ancestor or a system of beliefs has been raging for over two centuries. While the accumulated biological and anthropological evidence support the latter argument, recent genetic findings, bolstered by the direct-to-consumer genetic industry, purport to identify Jews or quantify one

Toward high-resolution population genomics using archaeological samples

The term 'ancient DNA' (aDNA) is coming of age, with over 1,200 hits in the PubMed database, beginning in the early 1980s with the studies of 'molecular paleontology'. Rooted in cloning and limited sequencing of DNA from ancient remains during the pre-PCR era, the field has made incredible progress since the introduction of PCR and next-generation sequencing. Over the last decade, aDNA analysis us

'Genome order index' should not be used for defining compositional constraints in nucleotide sequences--a case study of the Z-curve

BACKGROUND: The Z-curve is a three dimensional representation of DNA sequences proposed over a decade ago and has been extensively applied to sequence segmentation, horizontal gene transfer detection, and sequence analysis. Based on the Z-curve, a "genome order index," was proposed, which is defined as S = a2+ c2+t2+g2, where a, c, t, and g are the nucleotide frequencies of A, C, T, and G, respect

The genome sequence of the leaf-cutter ant Atta cephalotes reveals insights into its obligate symbiotic lifestyle

Leaf-cutter ants are one of the most important herbivorous insects in the Neotropics, harvesting vast quantities of fresh leaf material. The ants use leaves to cultivate a fungus that serves as the colony's primary food source. This obligate ant-fungus mutualism is one of the few occurrences of farming by non-humans and likely facilitated the formation of their massive colonies. Mature leaf-cutter

Insights into social insects from the genome of the honeybee Apis mellifera

Here we report the genome sequence of the honeybee Apis mellifera, a key model for social behaviour and essential to global ecology through pollination. Compared with other sequenced insect genomes, the A. mellifera genome has high A+T and CpG contents, lacks major transposon families, evolves more slowly, and is more similar to vertebrates for circadian rhythm, RNA interference and DNA methylatio

The genome of the sea urchin Strongylocentrotus purpuratus

We report the sequence and analysis of the 814-megabase genome of the sea urchin Strongylocentrotus purpuratus, a model for developmental and systems biology. The sequencing strategy combined whole-genome shotgun and bacterial artificial chromosome (BAC) sequences. This use of BAC clones, aided by a pooling strategy, overcame difficulties associated with high heterozygosity of the genome. The geno

The 'extremely ancient' chromosome that isn't : a forensic bioinformatic investigation of Albert Perry's X-degenerate portion of the Y chromosome

Mendez and colleagues reported the identification of a Y chromosome haplotype (the A00 lineage) that lies at the basal position of the Y chromosome phylogenetic tree. Incorporating this haplotype, the authors estimated the time to the most recent common ancestor (TMRCA) for the Y tree to be 338,000 years ago (95% CI=237,000-581,000). Such an extraordinarily early estimate contradicts all previous

Comprehensive Assessment of BARD1 Messenger Ribonucleic Acid Splicing With Implications for Variant Classification

Introduction: Case–control analyses have shown BARD1 variants to be associated with up to >2-fold increase in risk of breast cancer, and potentially greater risk of triple negative breast cancer. BARD1 is included in several gene sequencing panels currently marketed for the prediction of risk of cancer, however there are no gene-specific guidelines for the classification of BARD1 variants. We pres

Measurement of the top-quark mass in tt¯ + 1-jet events collected with the ATLAS detector in pp collisions at √s = 8 TeV

A determination of the top-quark mass is presented using 20.2 fb−1 of 8 TeV proton-proton collision data produced by the Large Hadron Collider and collected by the ATLAS experiment. The normalised differential cross section of top-quark pair production in association with an energetic jet is measured in the lepton+jets final state and unfolded to parton and particle levels. The unfolded distributi

Epidemiology of facial fractures : incidence, prevalence and years lived with disability estimates from the Global Burden of Disease 2017 study

BACKGROUND: The Global Burden of Disease Study (GBD) has historically produced estimates of causes of injury such as falls but not the resulting types of injuries that occur. The objective of this study was to estimate the global incidence, prevalence and years lived with disability (YLDs) due to facial fractures and to estimate the leading injurious causes of facial fracture.METHODS: We obtained

Burden of injury along the development spectrum : associations between the Socio-demographic Index and disability-adjusted life year estimates from the Global Burden of Disease Study 2017

development spectrum between 1990 and 2017 based on the Global Burden of Disease (GBD) 2017 estimates.METHODS: Injury mortality was estimated using the GBD mortality database, corrections for garbage coding and CODEm-the cause of death ensemble modelling tool. Morbidity estimation was based on surveys and inpatient and outpatient data sets for 30 cause-of-injury with 47 nature-of-injury categories
