Hereditary hypertrophic cardiomyopathy in children and young adults—The value of reevaluating and expanding gene panel analyses

Introduction: Sudden cardiac death (SCD) and early onset cardiomyopathy (CM) in the young will always lead to suspicion of an underlying genetic disorder. Incited by the rapid advances in genetic testing for disease we have revisited families, which previously tested “gene-negative” for familial predominantly pediatric CM, in hopes of finding a causative gene variant. Methods: 10 different familie

A historical account of the role of exercise in the prevention and treatment of cancer-related lymphedema

In the absence of guidance from scientific evidence, a range of lymphedema prevention and management, guidelines were developed by relevant organizations around the world. These became publicly available, promoted and endorsed, particularly to women with breast cancer. The recommendations advised avoidance of any activity that could overload or restrict the lymphatic system and need for caution wh

Assessment of lifestyle factors helps to identify liver fibrosis due to non-alcoholic fatty liver disease in obesity

Only some individuals with obesity develop liver fibrosis due to non-alcoholic fatty liver disease (NAFLD-fibrosis). We determined whether detailed assessment of lifestyle factors in addition to physical, biochemical and genetic factors helps in identification of these patients. A total of 100 patients with obesity (mean BMI 40.0 ± 0.6 kg/m2 ) referred for bariatric surgery at the Helsinki Univers

Principles of individual and small-quantity production processes

Processes in individual and mass production are governed by certain principles which need to be taken into account as early as the conceptual design phase. A comprehensive analysis of processes in tool production has shown that production also needs to be considered in remodeling or the introduction ofconcurrent engineering. The paper discusses the principles of the manufacturing process which aff

Towards an understanding of polynomial calculus : New separations and lower bounds (extended abstract)

During the last decade, an active line of research in proof complexity has been into the space complexity of proofs and how space is related to other measures. By now these aspects of resolution are fairly well understood, but many open problems remain for the related but stronger polynomial calculus (PC/PCR) proof system. For instance, the space complexity of many standard "benchmark formulas" is

Pebble games, proof complexity, and time-space trade-offs

Pebble games were extensively studied in the 1970s and 1980s in a number of different contexts. The last decade has seen a revival of interest in pebble games coming from the field of proof complexity. Pebbling has proven to be a useful tool for studying resolution-based proof systems when comparing the strength of different subsystems, showing bounds on proof space, and establishing size-space tr

Restoring grasslands in Kenya’s Rift Valley

Grasslands are a prerequisite for rearing livestock, and livestock is the mainstay of people’s existence in drylands. As one Kenyan woman put it, “without grass there is no livestock, without livestock there is no life.” Based in the lowlands of Baringo County in Kenya’s Rift Valley, RAE (Rehabilitating Arid Environments) Ltd. has worked for 38 years to develop a successful socio-ecological model

Parallel Kinematic Construction Robot for AEC Industry

This article reports work-in-progress of a parallel kinematic robot development for construction with main focus on the concept phase. We suppose the weight distribution of the proposed structure enables integration of robotic components into construction equipment while enabling tailoring of important characteristics such as accuracy, stiffness and workspace toward application needs.We describe c

A Nordic-Baltic perspective on indications for proton therapy with strategies for identification of proper patients

The beneficial effects of protons are primarily based on reduction of low to intermediate radiation dose bath to normal tissue surrounding the radiotherapy target volume. Despite promise for reduced long-term toxicity, the percentage of cancer patients treated with proton therapy remains low. This is probably caused by technical improvements in planning and delivery of photon therapy, and by high

Atomic Data Needs in Astrophysics: The Galactic Center “Scandium Mystery”

Investigating the Galactic center offers unique insights into the buildup and history of our Galaxy and is a stepping stone to understand galaxies in a larger context. It is reasonable to expect that the stars found in the Galactic center might have a different composition compared to stars found in the local neighborhood around the Sun. It is therefore quite exciting when recently there were repo

Evolution of sex chromosomes in Sylvioidea songbirds

Sex chromosomes were discovered more than 100 years ago. They have been studied intensely from a theoretical perspective since then, giving rise to a large body of testable predictions about their evolution from autosomes. A common feature of sex chromosomes is recombination suppression between the sex chromosome copies (X and Y in male heterogametic systems, or Z and W in female heterogametic sys
