LINE-2 transposable elements are a source of functional human microRNAs and target sites

Transposable elements (TEs) are dynamically expressed at high levels in multiple human tissues, but the function of TE-derived transcripts remains largely unknown. In this study, we identify numerous TE-derived microRNAs (miRNAs) by conducting Argonaute2 RNA immunoprecipitation followed by small RNA sequencing (AGO2 RIP-seq) on human brain tissue. Many of these miRNAs originated from LINE-2 (L2) e

Tensor-valued diffusion encoding for diffusional variance decomposition (DIVIDE) : Technical feasibility in clinical MRI systems

Microstructure imaging techniques based on tensor-valued diffusion encoding have gained popularity within the MRI research community. Unlike conventional diffusion encoding—applied along a single direction in each shot—tensor-valued encoding employs diffusion encoding along multiple directions within a single preparation of the signal. The benefit is that such encoding may probe tissue features t

How adaptive plasticity evolves when selected against

Adaptive plasticity allows organisms to cope with environmental change, thereby increasing the population's long-term fitness. However, individual selection can only compare the fitness of individuals within each generation: if the environment changes more slowly than the generation time (i.e., a coarse-grained environment) a population will not experience selection for plasticity even if it is ad

Second cancers and causes of death in patients with testicular cancer in Sweden

While treatment for testicular cancer (TC) has become standardized after the 1980s with an associated significant improvement in patient survival, this has been accompanied by an increased risk of second primary cancers (SPCs). Patients were identified from the Swedish Cancer Registry spanning the years from 1980 to 2015, including 8788 individuals with primary TC and their SPCs. Relative risks (R

Coherence and reliability of a wearable inertial measurement unit for measuring postural sway

OBJECTIVE: The aim of this study was to test the coherence of a wearable device, an inertial measurement unit (IMU) against the gold standard; also, to test the intra-trial reliability. This study has a cross-sectional design, where measurement of postural sway in the medio-lateral and anterior-posterior directions was performed simultaneously on a force plate and with a IMU called the Snubblomete

Machinery of Male Violence: Embodied Properties and Chronic Crisis amongst Partners in Vietnam

This article takes the notion of crisis as a helpful analytical entry point to unfold the tem- poralities and modalities of the machinery of violence as manifested in men’s abuse of their female partners in Vietnam. Based on ethnographic research I conducted over the years, the article argues that some types of crises might be episodic, and thus a bracketing of daily life, while others, such as in

Online Minimum-Jerk Trajectory Generation

Robotic trajectory generation is reformulated as a controller design problem. For minimum-jerk trajectories, an optimal controller using the Hamilton-Jacobi-Bellman equation is derived. The controller instantaneously updates the trajectory in a closed-loop system as a result of the changes in the reference signal. The resulting trajectories coincide with piece-wise fifth-order polynomial trajector

The Case for Interdisciplinary Crises Studies

In the world we live in today, the presence and claims of crisis abound – from climate change, financial and political crisis to depression, livelihoods and personal security crisis. There is a challenge to studying crisis due to the ways in which crisis as a notion, condition and experience refers to and operates at various societal levels. Further, different kinds of crisis can overlap and inter

European Qualitative research project on Patient-preferred outcomes in Early Rheumatoid Arthritis (EQPERA) : Rationale, design and methods of a multinational, multicentre, multilingual, longitudinal qualitative study

Introduction Including the patient perspective is important to achieve optimal outcomes in the treatment of rheumatoid arthritis (RA). Ample qualitative studies exist on patient outcomes in RA. A Belgian study recently unravelled what matters most to patients throughout the overwhelming and rapidly evolving early stage of RA. The present study, European Qualitative research project on Patient-pref

Treatment of radius or ulna fractures in the elderly : A systematic review covering effectiveness, safety, economic aspects and current practice

Background The objective of the present study was to evaluate effectiveness, complications and cost-effectiveness of any surgical or non-surgical treatment for radius or ulna fractures in elderly patients. Secondary objectives were to analyze present treatment traditions of distal radius fractures (DRF) in Sweden and to calculate resource usage for its treatment. Methods and findings The assessmen

Jet fragmentation transverse momentum measurements from di-hadron correlations in √s=7 TeV pp and √sNN=5.02 TeV p–Pb collisions

The transverse structure of jets was studied via jet fragmentation transverse momentum (j T ) distributions, obtained using two-particle correlations in proton-proton and proton-lead collisions, measured with the ALICE experiment at the LHC. The highest transverse momentum particle in each event is used as the trigger particle and the region 3 < p Tt < 15GeV/c is explored in this study. The measur

Heat transfer and flow structure in a rotating duct with detached pin fins

The realizable k - ε turbulence model was used to calculate flow and heat transfer characteristics in a rotating rectangular duct with detached pin fins in staggered arrangement. Transverse and longitudinal spacings of the pin fins were S 1 = 2.5 D and S 2 = 2.5 D, respectively. Reynolds number was 7,000 and Rotation number (Ro) varied from 0 to 1 while the clearance ranged from 0 to 0.5. Strea

Is high vitamin B12 status a cause of lung cancer?

Vitamin B supplementation can have side effects for human health, including cancer risk. We aimed to elucidate the role of vitamin B12 in lung cancer etiology via direct measurements of pre-diagnostic circulating vitamin B12 concentrations in a nested case–control study, complemented with a Mendelian randomization (MR) approach in an independent case–control sample. We used pre-diagnostic biomarke
