Developmental cues license megakaryocyte priming in murine hematopoietic stem cells

The fetal to adult switch in hematopoietic stem cell (HSC) behavior is characterized by alterations in lineage output and entry into deep quiescence. Here we identify the emergence of megakaryocyte (Mk) biased HSCs as an event coinciding with this developmental switch. Single-cell chromatin accessibility analysis reveals a ubiquitous acquisition of Mk lineage priming signatures in HSCs during the

Enhancing Rainfall-Runoff Simulation via Meteorological Variables and a Deep-Conceptual Learning-Based Framework

Accurate streamflow simulation is crucial for many applications, such as optimal reservoir operation and irrigation. Conceptual techniques employ physical ideas and are suitable for representing the physics of the hydrologic model, but they might fail in competition with their more advanced counterparts. In contrast, deep learning (DL) approaches provide a great computational capability for stream

Towards Social Negotiation : The Case of Handshake Debates in Sweden and Denmark

The refusal to shake hands with a female reporter by a Muslim politician from the Miljöpartiet resulted in a controversy in Sweden. Together with a number of court cases, it revealed a disparity between the established judicial line and the views of the general public. The Swedish controversy received a response from Denmark, where the ruling coalition introduced new citizenship legislation with a

Higher blood pressure in adolescent boys after very preterm birth and fetal growth restriction

BackgroundAlthough preterm birth predisposes for cardiovascular disease, recent studies in children indicate normal blood pressure and arterial stiffness. This prospective cohort study therefore assessed blood pressure and arterial stiffness in adolescents born very preterm due to verified fetal growth restriction (FGR).MethodsAdolescents (14 (13–17) years; 52% girls) born very preterm with FGR (p

Chronic cerebral blood flow alterations in traumatic brain injury and sports-related concussions

Primary Objective: Traumatic brain injury (TBI) and sports-related concussion (SRC) may result in chronic functional and neuroanatomical changes. We tested the hypothesis that neuroimaging findings (cerebral blood flow (CBF), cortical thickness, and 1H-magnetic resonance (MR) spectroscopy (MRS)) were associated to cognitive function, TBI severity, and sex. Research Design: Eleven controls, 12 athl

Striving with Global Stress on a Local Level : Has the COVID-19 Pandemic Changed the Relationship between People and Nature?

The COVID-19 pandemic had harsh consequences on human health and society across the globe. In addition to health effects, the pandemic also influenced people’s values, concerns, and ethics due to lockdowns and general limitations in societal activities. In this study, we examined changes in the relationship between people and nature caused by COVID-associated stress, as well as its consequences on

Evaluating Laboratory Measurements for Sound Insulation of Cross-Laminated Timber (CLT) Floors : Configurations in Lightweight Buildings

Cross-laminated timber (CLT) floors with supplementary layers or floating floors comprise a common solution in new multistory timber structures. However, bare CLT components provide poor sound insulation, especially in low frequencies during structure-borne sound propagation. Thus, floor configurations in wooden buildings deploy more layers for improved acoustic behavior. Twelve contemporary CLT f

Summertime Rossby waves in climate models : Substantial biases in surface imprint associated with small biases in upper-level circulation

In boreal summer, circumglobal Rossby waves can promote stagnating weather systems that favor extreme events like heat waves or droughts. Recent work showed that amplified Rossby wavenumber 5 and 7 show phase-locking behavior which can trigger simultaneous warm anomalies in different breadbasket regions in the Northern Hemisphere. These types of wave patterns thus pose a potential threat to human

SEPARATION OF CLUSTERS OF GROUP A STREPTOCOCCI USING DETERMINISTIC LATERAL DISPLACEMENT

Differences in morphologies of bacteria and bacteria clusters are known to influence their pathogenicity. However, it is difficult to separate cells and cell clusters based on morphology using standard cell biological methods, making studies of the underlying mechanisms difficult. Here we report a simple label-free method for the continuous separation of clusters of group A streptococci, based on

OPTIMISATION AND PERFORMANCE QUANTIFICATION ACOUSTIC TRAPPING USING SYNTHETIC NANOPARTICLES

Acoustic trapping is becoming increasingly popular as a tool to isolate and enrich biological nanoparticles [1] (particularly extracellular vesicles [2]), yet an inherent problem with acoustic trapping of nanoparticles is calibration of the trapping efficiency. This abstract presents in-house synthesized nanoparticles with different sound scattering properties, either rigid high density gold nanop

Long-term postural control in elite athletes following mild traumatic brain injury

Background: Traumas to the head and neck are common in sports and often affects otherwise healthy young individuals. Sports-related concussions (SRC), defined as a mild traumatic brain injury (mTBI), may inflict persistent neck and shoulder pain, and headache, but also more complex symptoms, such as imbalance, dizziness, and visual disturbances. These more complex symptoms are difficult to identif

CRISPR/CAS9 BASED DNA-COMBING ASSAY FOR DETECTING ANTIMICROBIAL RESISTANCE GENES ON PLASMIDS

We present a method based on CRISPR/Cas9 excision and DNA combing to detect anti-microbial resistance (AMR) genes on bacterial plasmids. The assay is inexpensive, simple, fast, and also provides information on the number and size of plasmids in a sample. We demonstrate detection of the gene encoding for the New Delhi metallobeta-lactamase 1 (blaNDM-1) enzyme, known to make bacteria resistant to a

Inertia induced breakdown of acoustic sorting efficiency at high flow rates

We investigated the impact of inertial forces on acoustic sorting at high sample throughputs. Above a critical flow rate, we observed an unexpected inertia induced breakdown of the sorting efficiency that is not due to the wall induced lift force and was not previously described in the literature. We analyzed the effect experimentally and theoretically, providing an explanation to the phenomena, a

Time-controlled Microbead-based Reactions in Droplets using Acoustophoresis

Droplet microfluidics is a powerful method to characterize chemical reactions at high throughput. Often detection is performed via in-line optical readout, which puts high demands on the detection system and makes detection of low concentration substrates challenging. Here, we have developed a droplet acoustofluidic chip for time-controlled microbead-based reactions that is combined with off-line

Nitrophobic ectomycorrhizal fungi are associated with enhanced hydrophobicity of soil organic matter in a Norway spruce forest

In boreal forests an important part of the photo assimilates are allocated belowground to support symbiosis of ectomycorrhizal fungi (EMF). The production of EMF extramatrical mycelium can contribute to carbon (C) sequestration in soils, but the extent of this contribution depends on the composition of the EMF community. Some species can decrease soil C stocks by degrading soil organic matter (SOM

Examining multiple-contact miscibility in reservoir drainage using a rock-on-a-chip

A series of experiments are carried out to exam the effect of multiple-contact miscibility on drainage using a rock-on-a-chip. The result shows the distinct behaviors depending on the composition and injection flow rate. The observations are compared with the classical parameter regime diagram for drainage displacement of R. Lenormand et al[1].

Enabling Long-term Predictions and Cost-benefit Analysis Related to Housing Adaptation Needs for a Population Aging in Place : Protocol for a Simulation Study

Background: Policies that promote aging in place are common in Sweden and many other countries. However, the current housing stock cannot sufficiently accommodate a population aging in place considering how functional capacity and housing needs change as people age. To be suitable for all regardless of their functional ability, housing should be designed or adapted to facilitate the performance of

Exercise-induced myocardial edema in master triathletes : Insights from cardiovascular magnetic resonance imaging

Background: Strenuous exercise has been associated with functional and structural cardiac changes due to local and systemic inflammatory responses, reflecting oxidative, metabolic, hormonal, and thermal stress, even in healthy individuals. We aimed to assess changes in myocardial structure and function using cardiovascular magnetic resonance (CMR) imaging in master triathletes early after a full-d
