Background/Aims: Hemodialysis implies significant alterations in the profile of serum components. microRNAs (miRNAs) are present in the human serum and are considered to target distant tissues where they can regulate gene expression, thus affecting homeostasis. Whether hemodialysis alters the profile of miRNAs in the serum is not known. Methods: miRNA profiling in serum samples collected before an

A life-view can be described an an overall view of man and the world. An individual's life-view can change as a result of attending university. The life-view determines the response to reality and influences decision making and the treatment of other people. The aim of this study is to compare life-views and ethical viewpoints in the same group of physiotherapy students in their first and last sem

A drilling task requires a mechanism with five degrees of freedom, in order to achieve the correct position and orientation of the drilling tool. When performed with a standard 6-axes industrial robot, this task leaves an extra degree of freedom that can be exploited in order to achieve any additional criterion. Unfortunately, typical industrial robotic control architectures do not allow the user

The time evolution of incipient necks is studied numerically for planar and axisymmetric bars subject to high-rate extension. The material is taken to be elastic-plastic and fully non-linear dynamic effects are accounted for. Two main types of growth of necks are observed; stable neck-development that results in fully developed necks and unstable neck-development that leads to weakly developed nec

The 19th century was a period of great transformations for Italy. Political unification was achieved in 1861 while economic unification was still far off. Ever since, Italian industrialization has been unbalanced, as the pre-existing gap between Northern and Southern economic development has widened. In this context, the creation of the Italian national market has been a highly debated topic. Orig

Ruptures to tendons are common and costly, and no clinical consensus exists on the appropriate treatment and rehabilitation regimen to promote their healing as well as full recovery of functionality. Although mechanobiology is known to play an important role in tendon regeneration, the understanding of how mechano-regulated processes affect tendon healing needs further clarification. Many small-an

IntroductionPost-operative infections obtained from open-wound surgeries constitute an unnecessary load on both healthcare and affected patients. It is well established that increased air cleanliness reduces the number of post-operative infections. Therefore, the ventilation system is important in order to reduce the number of infectious particles in the air during surgery. Ventilation with high a

For all flyers, aeroplanes or animals, making banked turns involve a rolling motion which, due to higher induced drag on the outer than the inner wing, results in a yawing torque opposite to the turn. This adverse yaw torque can be counteracted using a tail, but how animals that lack tail, e.g. all insects, handle this problem is not fully understood. Here, we quantify the performance of turning t

We study the jet quenching parameter qˆ in the initial pre-equilibrium stages of heavy-ion collisions using the QCD kinetic theory description of the anisotropic quark-gluon plasma. This allows us to smoothly close the gap in the literature between the early glasma stage of the collision and the onset of hydrodynamics. We find that the pre-hydrodynamic evolution of qˆ during the bottom-up kinetic

The autonomic nervous system (ANS) is an important factor in cardiac arrhythmia, and information about ANS activity during atrial fibrillation (AF) may contribute to personalized treatment. In this study we aim to quantify respiratory modulation in the f-wave frequency trend from resting ECG. First, an f-wave signal is extracted from the ECG by QRST cancelation. Second, an f-wave model is fitted t

AbstractBackground: Areal bone mineral density (aBMD) measured by dual-energy X-ray absorptiometry (DXA) is a surrogate estimate of bone strength. The highest value in life is referred to “peak bone mass” (PBM). In the femoral neck (FN), PBM is reached late in the second decade in life, after which there is an age-related decline in aBMD during adulthood. However, a decrease in aBMD may follow a d

This chapter discusses ethical concerns when conducting fieldwork on a sensitive topic in a development setting. Research on AIDS has been conducted in various settings and within various fields of science since its outbreak and has raised ethical dilemmas for the researchers. In this chapter the issues of fieldwork, vulnerable groups, power relations and sensitive research are discussed. The prac

Behavioral variation has been documented both between and within populations in a variety of traits. Many of these behavioral traits are phenotypically plastic and are conditional on the early environment an animal experiences, yet despite this the role of the environment in generating variation in boldness is not well understood. Here we investigate the importance of early and recent experience o
