Targeted metagenomics – Enrichment for enzymes active on sulfated polysaccharides from seaweeds

Seaweeds (macroalgae) are an attractive resource for diverse microbial- and enzymatic production processes. They are abundant, underutilized, cheap, and rich in carbohydrates, and therefore have the potential to be used as a source of mono- or oligosaccharides, and as substrates for industrial fermentation processes. Many seaweed polysaccharides, including the sulfated polysaccharides ulvan and fu

Walking by design : how to build artificial molecular motors made of proteins

To design an artificial protein-based molecular motor that can autonomously step along a track is a key challenge of protein design and synthetic biology. We lay out a roadmap for how to achieve this aim, based on a modular approach that combines the use of natural, non-motor proteins with de novo design. We define what can be considered to constitute a successful artificial protein motor, identif

On May 26, 2021, the European Medical Device Regulation (EU-MDR) entered into effect resulting in a major shift in the requirements for assessment of medical devices in Europe. The EU-MDR Cardiovascular Collaboratory (EU-MCVC) was founded to contribute to the development of faster, more efficient, and more effective pathways for innovation of cardiac medical devices. A registry is an organized sys

Algae potential resource assessment for the energy and chemistry sectors in France by 2030

To address environmental and climate issues, alternative technologies to fossil resources are sought after, both for the production of fuels and of chemicals. Algae appear as an attractive solution and have applications in the food, feed, energy or chemistry at large. A study funded by ADEME and conducted by ENEA, a consulting firm for energy and sustainable development for the industrial sector,

Assessing grain boundary variability through phase field crystal simulations

Characterization of grain boundaries (GBs) typically focuses exclusively on ideal minimum-energy structures,thus offering a limited perspective on the potential structural diversity and related property variations of GBs.In this study, phase field crystal (PFC) simulations are employed to systematically explore alternative GBstates through γ -surface sampling. A large number of tilt and twist GBs

3D distribution of biomineral and chitin matrix in the stomatopod dactyl club by high energy XRD-CT

Stomatopods are ferocious hunters that use weaponized appendages to strike down their pray. The clubs of species such as Odontodactylus scyllarus undergo tremendous forces, and in consequence they have intricate structures, consisting of hydroxyapatite, chitin, amorphous calcium phosphate and carbonate, and occasionally calcite. These materials are distributed differently across the four major zon

A 1D imaging soft X-ray spectrometer for the small quantum systems instrument at the European XFEL

A 1D imaging soft X-ray spectrometer installed on the small quantum systems (SQS) scientific instrument of the European XFEL is described. It uses movable cylindrical constant-line-spacing gratings in the Rowland configuration for energy dispersion in the vertical plane, and Wolter optics for simultaneous 1D imaging of the source in the horizontal plane. The soft X-ray fluorescence spectro-imaging

An overview of the ESS cryogenic system and its design evolution

Superconductivity and cryogenics were recognized as necessary to the European Spallation Source (ESS) project from its earliest days. This chapter provides a highlevel overview of the ESS cryogenics system and describes the reasoning behind early conceptual design choices. Some requirements for the cryogenic system did change over time and that evolution is discussed. In addition, the recruitment

The Gut Microbiota and Diabetes : Research, Translation, and Clinical Applications—2023 Diabetes, Diabetes Care, and Diabetologia Expert Forum

This article summarizes the state of the science on the role of the gut microbiota (GM) in diabetes from a recent international expert forum organized by Diabetes, Diabetes Care, and Diabetologia, which was held at the European Association for the Study of Diabetes 2023 Annual Meeting in Hamburg, Germany. Forum participants included clinicians and basic scientists who are leading investigators in

Perturbation theory for embedded eigenvalues of asymptotically periodic operators

This thesis explores the persistence of embedded eigenvalues of asymptotically periodic Schrödinger-type operators under perturbations on domains with only one unbounded direction. Embedded eigenvalues present unique challenges, as they lie within the continuous spectrum, making their stability under perturbations a nontrivial problem.The aim of the first part of the thesis is to provide a general

Treating the disease and meeting the person with the illness-patient perspectives of needs during infective endocarditis, a qualitative study

Background Infective endocarditis (IE) is a rare but severe infectious disease. Patients with IE are treated for weeks in the hospital and have profound impairments to their health. New treatment modalities increase options for outpatient care. Little is known about how patients perceive their disease and hospitalisation. We aimed to explore the needs of patients with IE during hospitalisation and

Correlation between electrical resistivity and compressive strength of stabilized dredged sediment for early quality control

Quality control of stabilized dredged sediment (DS) presents significant challenges due to its high-water content. Nowadays, many in-situ and laboratory tests have been used to evaluate the quality of treated DS, and the dominant method is 28-day unconfined compressive strength that can be done on undisturbed samples from the field and the laboratory. Due to the waiting period to get results from

Examining senior citizens’ in public transport : The role of digitalization, environmental concern, and traveler satisfaction

Increasing the share of travelers using public transport is one way to address environmental problems such as carbon dioxide emissions. Senior citizens represent an increasingly important group in this transition, as they are increasingly mobile and make up a large share of the population. In this paper, we investigate senior citizen's mobility decision-making, focusing on public transport. Throug

ProstateZones – Segmentations of the prostatic zones and urethra for the PROSTATEx dataset

Manual segmentations are considered the gold standard for ground truth in machine learning applications. Such tasks are tedious and time-consuming, albeit necessary to train reliable models. In this work, we present a dataset with expert segmentations of the prostatic zones and urethra for 200 randomly selected patients from the PROSTATEx dataset. Notably, independent duplicate segmentations were

Modern CRRT systems are associated with lower risk of hypothermia

One risk of continuous renal replacement therapy (CRRT) is inadvertent hypothermia (IH), which is defined as a non-therapeutic core temperature decrease below normal. In continuous renal replacement therapy, heat loss will always occur from blood pumped through the dialysis circuit to cooler environment, predisposing for hypothermia. Blood flow and effluent flows are the most important parameters

Exploring the factors influencing the ketoenamine-enolimine tautomeric equilibrium of pyridoxal 5′-phosphate in branched-chain aminotransferases

Pyridoxal 5′-phosphate (PLP), the active form of vitamin B6, is a critical coenzyme for various enzymes. It generates a Schiff base with the substrate and exhibits ketoenamine and enolimine tautomeric forms due to intramolecular proton transfer. This study aims to ascertain the predominant tautomeric form of the PLP Schiff base in MtIlvE and analyze its influencing factors. Molecular dynamics simu

The potential of alkaline tolerant microbial consortia for textile wastewater treatment under integrated anaerobic/aerobic conditions : Performance evaluation and microbial community analysis

Sequential anaerobic/aerobic (A/O) treatment conditions for textile wastewater (WW) are more effective than conventional biological treatment. Anaerobic treatment is essential because anaerobic microbes can first break down complex and recalcitrant compounds, which are difficult to degrade under aerobic conditions. The simpler, more degradable compounds are then further broken down by aerobic micr
