Lipoprotein metabolism mediates hematopoietic stem cell responses under acute anemic conditions

Hematopoietic stem cells (HSCs) react to various stress conditions. However, it is unclear whether and how HSCs respond to severe anemia. Here, we demonstrate that upon induction of acute anemia, HSCs rapidly proliferate and enhance their erythroid differentiation potential. In severe anemia, lipoprotein profiles largely change and the concentration of ApoE increases. In HSCs, transcription levels

Single vertical InP nanowire diodes with low ideality factors contacted in-array for high-resolution optoelectronics

Nanowire (NW) optoelectronic and electrical devices offer unique advantages over bulk materials but are generally made by contacting entire NW arrays in parallel. In contrast, ultra-high-resolution displays and photodetectors require electrical connections to individual NWs inside an array. Here, we demonstrate a scheme for fabricating such single NW vertical devices by contacting individual NWs w

Adaptive reinforcement learning for energy management : A progressive approach to boost climate resilience and energy flexibility

Energy management in urban areas is challenging due to diverse energy users, dynamics environmental conditions, and the added complexity and instability of extreme weather events. We incorporate adaptive reinforcement learning (ARL) into energy management (EM) and introduce a novel approach, called ARLEM. An online, value-based, model-free ARL engine is designed that updates its policy periodicall

Emergent Behavior of Living Neuronal Networks : Creating circuits and exploring the dynamics of neurons in vitro

In the past two decades there’s been an incredible development in the field of in vitro neural cultures. Thanks to the developments in embryonic stem cell technology, and the ability to produce pluripotent stem cells from adult human cells, producing human neural cultures has become much more widely accessible, and the ability to recreate physiological processes is increasing at an accelerating ra

Pathogen Contamination of Groundwater Affecting Drinking Water Quality with Potential Health Effects in Pavlodar Region, Kazakhstan

Groundwater is becoming increasingly important as surface water is decreasing and becoming more and more polluted. In particular, rural areas in the arid region of Central Asia face problems with both water quantity and quality. In view of this, we investigated the drinking water quality in the Maysky district in the Pavlodar region, Kazakhstan. The organoleptic properties, together with microbiol

Experimental species removal reveals species contributions to positive pollinator-mediated reproductive interactions

Pollinator-mediated reproductive interactions among co-flowering plant species provide a canonical example of how biotic factors may contribute to species coexistence, yet we lack understanding of the exact mechanisms. Flowering-dominant and unusually attractive “magnet species” with disproportionate contributions to pollination may play key roles in such reproductive interactions, but their relat

Social-class differences in spacing and stopping during the historical fertility transition: Insights from cure models

Background: There is a long-standing debate about the role of spacing and stopping in the fertility transition, fueled by a lack of methods to appropriately model spacing and stopping. Traditional event-history analysis cannot distinguish between the two processes in analyzing the determinants of birth risks, and attempts to separately model spacing and stopping have been criticized from a methodo

Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. The technique has applications in cancer detection but is limited in penetration as the magnetic field decreases rapidly with distance. Instead of increasing

Prior cancer and risk of monoclonal gammopathy of undetermined significance : a population-based study in Iceland and Sweden

There is some evidence that a prior cancer is a risk factor for the development of multiple myeloma (MM). If this is true, prior cancer should be associated with a higher prevalence or increased progression rate of monoclonal gammopathy of undetermined significance (MGUS), the precursor of MM and related disorders. Those with a history of cancer might therefore constitute a target population for M

When theory meets practice in transformative innovation policy evaluation: experiences from Sweden

Government policies increasingly focus on transformative innovation policy (TIP), as programmes are being reoriented towards addressing societal challenges and contributing to sustainability transitions. Evaluation practices need modification to keep up with this change. While a small number of frameworks for TIP evaluation have been proposed, building upon different sustainability transition appr

GTP Hydrolysis Without an Active Site Base : A Unifying Mechanism for Ras and Related GTPases

GTP hydrolysis is a biologically crucial reaction, being involved in regulating almost all cellular processes. As a result, the enzymes that catalyze this reaction are among the most important drug targets. Despite their vital importance and decades of substantial research effort, the fundamental mechanism of enzyme-catalyzed GTP hydrolysis by GTPases remains highly controversial. Specifically, ho

“Everyone decided to declare war on the forest”: between territorial peace and pacification in the Colombian Andean-Amazon

In post-peace agreement Colombia, everyone declared war on the forest. In the Putumayo region, these wars take their own particular forms. Scientifically, the Putumayo is described as an Andean-Amazonic rainforest. For the indigenous and local inhabitants of the Putumayo, it is the Andean-Amazonic selva. We present three wars on the forest with material and discursive specificities and critically

Dose conversion in retrospective dosimetry : Results and implications from an inter-laboratory comparison featuring a realistic exposure scenario

Dose conversion coefficients attempt to harmonize the material-, location-, and exposure-dependent results from retrospective dosemeters. The issues and uncertainties arising from dose conversion are explored within the framework of an interlaboratory comparison exercise in which mobile phones were positioned around anthropomorphic phantoms and exposed to non-uniform photon fields, with the glass

Integrating molecular photoswitch memory with nanoscale optoelectronics for neuromorphic computing

Photonic solutions are potentially highly competitive for energy-efficient neuromorphic computing. However, a combination of specialized nanostructures is needed to implement all neuro-biological functionality. Here, we show that donor-acceptor Stenhouse adduct dyes integrated with III-V semiconductor nano-optoelectronics have combined excellent functionality for bio-inspired neural networks. The

Health-promoting text messages to patients with hypertension—A randomized controlled trial in Swedish primary healthcare

Due to the high prevalence and great cardiovascular risks of hypertension, we need effective and evidence-based treatment strategies. Health-promoting one-way text messages could be a beneficial complement to antihypertensive drugs. However, this has yet to be proven in a primary healthcare setting. The purpose of this study was to investigate if health-promoting text messages could improve patien

Autoimmune Type 1 Diabetes

The last several years of research, including children followed from birth and extensive genetic studies, have resulted in a paradigm shift of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Autoimmune T1DM is characterized by the appearance in early childhood of a first β-cell autoantibody against either insulin (IAA) or GAD65 (GADA), or both. The genetic etiology is strongly as
