Lateral gene transfer (LGT) is an important mechanism of evolution for protists adapting to oxygen-poor environments. Specifically, modifications of energy metabolism in anaerobic forms of mitochondria (e.g., hydrogenosomes) are likely to have been associated with gene transfer from prokaryotes. An interesting question is whether the products of transferred genes were directly targeted into the an

Background Many microbial eukaryotes have evolved anaerobic alternatives to mitochondria known as mitochondrion-related organelles (MROs). Yet, only a few of these have been experimentally investigated. Here we report an RNA-seq-based reconstruction of the MRO proteome of Pygsuia biforma, an anaerobic representative of an unexplored deep-branching eukaryotic lineage. Results Pygsuia's MRO has a co

There is little doubt that genes can spread across unrelated prokaryotes, eukaryotes and even between these domains. It is expected that organisms inhabiting a common niche may exchange their genes even more often due to their physical proximity and similar demands. One such niche is anaerobic or microaerophilic environments in some sediments and intestines of animals. Indeed, enzymes advantageous

Most of the major groups of eukaryotes have microbial representatives that thrive in low oxygen conditions. Those that have been studied in detail generate ATP via pathways involving anaerobically functioning enzymes of pyruvate catabolism that are typically absent in aerobic eukaryotes and whose origins remain controversial. These enzymes include pyruvate:ferredoxin oxidoreductase, pyruvate:NADP+

Accurate determination of the bearing capacity of bridges is of high importance for society. Concerns are raised about the actual bearing capacity of bridges due to aging related deterioration, ever increasing traffic loads and conservative design. Proof load testing is often used for evaluations of bridge capacity. However, extensive proof load tests tend to be costly. Further, the risks of damag

Animals move in ‘modes’ where movement patterns relate to specific behaviours. Despite much work on the movement of butterflies, their behavioural modes are relatively unexplored. Here we analysed the behaviour of the model butterfly species the meadow brown, Maniola jurtina. We identified modes in both sexes and across habitats varying in resource density. We found that, in nectar-rich habitats,

TitleValidation of the Swedish version of the Beliefs about Medicines Questionnaire, based on people with epilepsy.PurposeThe aims of the study were to explore the latent structure of the Swedish Beliefs about Medicines Questionnaire (BMQ), to investigate its reliability and to identify the extent to which individual factors among people with epilepsy (PWE), as well as their general beliefs about

Objective: Few studies have examined factors associated with patient’s choice of particular psychological treatments. The present study explores possible associations to, and the reasons given for, patient’s choice of Panic Control Treatment (PCT) or Panic-Focused Psychodynamic Psychotherapy (PFPP) for Panic Disorder with or without Agoraphobia (PD/A). Method: Both quantitative and qualitative ana

There is increasing interest concerning daylighting in the building sector. However, such knowledge is difficult to penetrate the curricula of architects and designers as existing educational programmes often do not provide sufficient training on BPS. This also leads to superficial use of daylight simulations.This paper presents a proposal for a needs-based education package on daylighting design,

This paper analyzes the long-term effects of potentially avoidable cesarean sections on children’s health. Using Finnish administrative data, we document that physicians perform more unplanned C-sections during their regular working hours on days that precede a weekend or public holiday and use this exogenous variation as an instrument for C-sections. We supplement our instrumental variables resul

We investigate local convergence of identical DC/AC converters interconnected via identical resistive and inductive lines towards a synchronous equilibrium manifold. We exploit the symmetry of the resulting vector field and develop a Lyapunov-based framework, in which we measure the distance of the solutions of the nonlinear power system model to the equilibrium manifold by analyzing the evolution

This chapter examines changes to safe third country law and practice from 2010 to 2020 focusing on Europe, Australia, North, and South America. These developments have received little academic attention, particularly from a comparative perspective. We argue that in all four regions there has been a significant weakening of protection standards in the safe third country context, with the thresholds

Smart cyber-physical systems (S-CPSs) are complex engineered systems empowered by cyber-physical computing and equipped with the capability of reasoning, learning, adapting, and evolving. As an outcome of data-driven dynamic computing, reasoning capabilities, and the run-time obtained own knowledge, nonlinear and emergent behavior of S-CPSs whilst in operation is an open issue, not experienced in
