Cell culturing methods are increasingly used to reduce and replace the use of live animals in biomedical research and chemical toxicity testing. Although live animals are avoided when using cell culturing methods, they often contain animal-derived components of which one of the most commonly used is foetal bovine serum (FBS). FBS is added to cell culture media among other supplements to support ce

Memristors implemented as resistive random-access memories (RRAMs) owing to their low power consumption, scalability, and speed are promising candidates for in-memory computing and neuromorphic applications. Moreover, a vertical 3D implementation of RRAMs enables high-density crossbar arrays at a minimal footprint. Co-integrated III–V vertical gate-all-around MOSFET selectors in a one-transistor-o

Vanadium oxides exist in a multitude of phases with varying structure and stoichiometry. This abundance of phases can be extended through the use of other oxides as supports, and through redox treatments. However, the combined effects of different supports and redox treatments can be difficult to identify, particularly when present as different terminating facets on nanoparticles. Here, we examine

Background: Differences in the performance of estimated glomerular filtration rate (eGFR) equations have been attributed to the mathematical form of the equations and to differences between patient demographics and measurement methods. We evaluated differences in serum creatinine (SCr) and eGFR in cohorts matched for age, sex, body mass index (BMI) and measured GFR (mGFR). Methods: White North Ame

Catalytic processes are present in a wide range of aspects, from fundamental biological processes to modern chemical synthesis. In practical terms, catalysis has thrived as a rapidly growing industry. However, a significant gap in our understanding of catalytic processes exists between the molecular and industrial scales, arising from the complexity at the nano- and micro-levels of catalytic nanop

Investigation of how one can control the oxidation of engineered nanoparticles by using different carrier gases.

AIM: Breath-holding spells (BHS) are common in children, but evidence-based clinical guidelines are lacking. We investigated a large population-based cohort of BHS patients, to propose a refined description of typical BHS and guidelines for its management.METHODS: In a cross-sectional retrospective study, patients diagnosed with BHS in Southern Sweden 2004-2018 were recruited. Disease characterist

To prevent diseases arising from exposure to toxic metals, more knowledge about their temporal changes is needed, especially in children, the most vulnerable group. This study follows temporal changes in blood lead (BPb), mercury (BHg) and cadmium (BCd) levels in schoolchildren (8–11 years old) from two cities in southern Sweden. One blood sample per 773 children was used for time trend analyses b

As the proverbial noose tightens around humanity’s resource spending, research is focused on utilizing materials to their fullest potential. Nanotechnology is the ultimate way to economize by splitting objects into smaller parts and dispersing the material properties over greater surface to volume ratios. Emerging quantum effects at the nanoscale present unique tweaking opportunities in applicatio

The use of aluminum-magnesium (Al-Mg) alloy particle as energetic additive in solid propellants was previously shown to have many advantages over pure Al particle, such as relatively low ignition temperature, high reaction rate and low particle agglomeration rate. In this paper, the combustion of Al-Mg alloy in hot H2O/O2/N2 flows was experimentally studied using wires with a diameter of 200 µm. T

Oxide defects in the high-k/InGaAs MOS system are investigated. The behaviour of these traps is explored from room temperature down to 10 K. This study reveals that the exchange of free carriers between oxide states and either the conduction or the valence band is strongly temperature dependant. The capture and emission of electrons is strongly suppressed at 10 K as demonstrated by the collapse of

INTRODUCTION: Mammographic breast density (MBD) is an established breast cancer risk factor, yet the underlying molecular mechanisms remain to be deciphered. Fibroblast growth factor receptor 1 (FGFR1) amplification is associated with breast cancer development and aberrant FGF signaling found in the biological processes related to both high mammographic density and breast cancer microenvironment.

Air pollution affects human health and is particularly bad for susceptible groups, such as children. Health effects of air pollution are dependent on the particle deposition in the respiratory tract. To better understand the particle deposition for children we need to gain more knowledge about how and when the structure of the peripheral lung is developed.1

The polarization switching dynamics for Hf 1-x Zr x O 2 (HZO) integrated on InAs is studied as a function of pulse width and amplitude. Due to a mixed ferroelectric/antiferroelectric phase at x=0.8, a more gradual total polarization update is shown compared to a fully ferroelectric Hf 0.5 Zr 0.5 O 2 stack. A lowered operating voltage is achieved in Hf 0.2 Zr 0.8 O 2 by activating an inner ferroele

CsPbI3 nanocrystals (CPI NCs) have become a trending research topic due to their impressive potential in functional optoelectronic devices and optical gain applications. Their optical responses are governed by carrier dynamics, which is greatly influenced by temperature and corresponding phase structure due to the effects of inherently electron-phonon coupling. Notably, CPI NCs have been identifie

Here we describe an in vitro co-culture system that can differentiate hematopoietic progenitor populations to all major hematopoietic lineages at clonal level. We present both a sensitive single-cell switch-culture system as well as a less laborious alternative barcoding protocol more convenient for larger cell numbers. Importantly, generation of all lineages from single long-term hematopoietic st

Objective: To determine the risk of comorbidity following diagnosis of knee or hip osteoarthritis (OA). Design: A cohort study was conducted using the Integrated Primary Care Information database, containing electronic health records of 2.5 million patients from the Netherlands. Adults at risk for OA were included. Diagnosis of knee or hip OA (=exposure) and 58 long-term comorbidities (=outcome) w
