Predicting type 2 diabetes via machine learning integration of multiple omics from human pancreatic islets

Type 2 diabetes (T2D) is the fastest growing non-infectious disease worldwide. Impaired insulin secretion from pancreatic beta-cells is a hallmark of T2D, but the mechanisms behind this defect are insufficiently characterized. Integrating multiple layers of biomedical information, such as different Omics, may allow more accurate understanding of complex diseases such as T2D. Our aim was to explore

Tuning the Performance of Poly(quaterphenyl piperidinium) Anion-Exchange Membranes by Monomer Configuration

Poly(arylene piperidinium)s are attractive anion exchange membranes (AEMs) for alkaline membrane fuel cells and water electrolyzers because of their high chemical stability and hydroxide conductivity. Here, ether- and fluorine-free hydroxide conducting poly(quaterphenyl piperidinium) membranes with very similar ion exchange capacity (IEC), but different ratios of meta to para connectivity in the q

Social isolation and risk-taking behavior : The case of COVID-19 and cryptocurrency

This study examines the impact of social isolation on risk-taking behavior in highly uncertain environments with the potential for significant gains and losses. We uncover both direct and indirect effects of social isolation on risk-taking behavior, mediated through perceived stress, sense of control, and neuroticism. The COVID-19 pandemic provides a pertinent context to explore these dynamics, wh

Patients’ experiences of clinical trial participation involving a product remotely assessing study drug adherence

Background: The participation of patients in clinical trials is crucial for the development of healthcare. There are several challenges in the recruitment of trial participants with acute medical conditions. The registry-based randomized DAPA-MI clinical trial recruited patients during hospitalization for myocardial infarction and provided study drugs in bottles with smart caps that used wireless

Amyloid-PET imaging predicts functional decline in clinically normal individuals

Background: There is good evidence that elevated amyloid-β (Aβ) positron emission tomography (PET) signal is associated with cognitive decline in clinically normal (CN) individuals. However, it is less well established whether there is an association between the Aβ burden and decline in daily living activities in this population. Moreover, Aβ-PET Centiloids (CL) thresholds that can optimally predi

Drop breakup at reduced energy cost using a turbulent pulse –implications for improving efficiency in emulsification devices

Emulsification devices break drops by rapidly pushing them through a region of intense turbulence–a ‘turbulent pulse’. These devices are widely used in chemical engineering. However, the thermodynamic efficiency is low, and design modifications allowing more breakup at lower energy input is much in need. This study uses a combination of statistical models and direct numerical simulation coupled to

Staphylococcus aureus carriage and prevalence of skin and soft tissue infections among people who inject drugs : a longitudinal study

People who inject drugs are frequently colonized with Staphylococcus aureus and have an increased risk for skin and soft tissue infections. This longitudinal study aims to describe S. aureus carriage in this group and the risk for infections during a 1-year follow-up. We included 61 participants from the Malmö Needle Exchange Program. Mapping of S. aureus carriage was conducted by screening cultur

Quality assessment of radiotherapy in the prospective randomized SENOMAC trial

Background and purpose: Recommendations for regional radiotherapy (RT) of sentinel lymph node (SLN)-positive breast cancer are debated. We here report a RT quality assessment of the SENOMAC trial. Materials and Methods: The SENOMAC trial randomized clinically node-negative breast cancer patients with 1–2 SLN macrometastases to completion axillary lymph node dissection (cALND) or SLN biopsy only be

Orthonormal expansions for translation-invariant kernels

We present a general Fourier analytic technique for constructing orthonormal basis expansions of translation-invariant kernels from orthonormal bases of ℒ2(R). This allows us to derive explicit expansions on the real line for (i) Matérn kernels of all half-integer orders in terms of associated Laguerre functions, (ii) the Cauchy kernel in terms of rational functions, and (iii) the Gaussian kernel

Flood vulnerability mapping in an urban area with high levels of impermeable coverage in southern Brazil

Flooding is one of the main social impacts in urban areas, especially in larger, densely impermeable cities. Therefore, developing studies capable of identifying areas that are vulnerable to this type of event is crucial to provide early warning and a quick and effective response to reduce damages. Thus, this study sought to identify areas vulnerable to flood in the Igapó Lake Basin, a densely urb

Recruitment and migration patterns reveal a key role for seed banks in the meta-population dynamics of an aquatic plant

Progressive habitat fragmentation threatens plant species with narrow habitat requirements. While local environmental conditions define population growth rates and recruitment success at the patch level, dispersal is critical for population viability at the landscape scale. Identifying the dynamics of plant meta-populations is often confounded by the uncertainty about soil-stored population compar

Structure of cellulose in birch phloem fibres in tension wood : an X-ray nanodiffraction study

Background: To gain a better understanding of bark layer structure and function, especially of the phloem fibres and their contribution to the posture control of trees, it is important to map the structural properties of these cells. The role of bark can also be linked to the reaction wood formation and properties which are essential when it comes to studying the questions related to tree growth.

Extracellular matrix sensing via modulation of orientational order of integrins and F-actin in focal adhesions

Specificity of cellular responses to distinct cues from the ECM requires precise and sensitive decoding of physical information. However, how known mechanisms of mechanosensing like force-dependent catch bonds and conformational changes in FA proteins can confer that this sensitivity is not known. Using polarization microscopy and computational modeling, we identify dynamic changes in an orientati

The microphysics of the warm-rain and ice crystal processes of precipitation in simulated continental convective storms

Precipitation in clouds can form by either warm-rain or ice crystal processes, referred to as warm and cold formation pathways, respectively. Here, we investigate the warm and cold pathway contributions to surface precipitation in simulated continental convective storms. We analyze three contrasting convective storms that are cold-based, slightly warm-based and very warm-based. We apply tracer-tag

Plasma protein N-glycome composition associates with postprandial lipaemic response

Background: A dysregulated postprandial metabolic response is a risk factor for chronic diseases, including type 2 diabetes mellitus (T2DM). The plasma protein N-glycome is implicated in both lipid metabolism and T2DM risk. Hence, we first investigate the relationship between the N-glycome and postprandial metabolism and then explore the mediatory role of the plasma N-glycome in the relationship b

Det allmänna som avtalspart : Särskilt avseende kommuns kompetens att ingå avtal samt avtalens rättsverkningar

This thesis deals with local government bodies, especially municipalities, as parties to contracts. It primarily focuses on general problems relating to the competence of a municipality to enter into contracts, and the subsequent legal effects, in light ofthe principles and rules ofpublic and private law. When analysing a contract to which a governmental body is a party, it is necessary to conside

Improving serious illness communication : a qualitative study of clinical culture

OBJECTIVE: Communication about patients' values, goals, and prognosis in serious illness (serious illness communication) is a cornerstone of person-centered care yet difficult to implement in practice. As part of Serious Illness Care Program implementation in five health systems, we studied the clinical culture-related factors that supported or impeded improvement in serious illness conversations.

External validation of the CREST model to predict early circulatory-etiology death after out-of-hospital cardiac arrest without initial ST-segment elevation myocardial infarction

Background: The CREST model is a prediction model, quantitating the risk of circulatory-etiology death (CED) after cardiac arrest based on variables available at hospital admission, and intend to guide the triage of comatose patients without ST-segment-elevation myocardial infarction after successful cardiopulmonary resuscitation. This study assessed performance of the CREST model in the Target Te

Electrostatic interactions control the adsorption of extracellular vesicles onto supported lipid bilayers

Communication between cells located in different parts of an organism is often mediated by membrane-enveloped nanoparticles, such as extracellular vesicles (EVs). EV binding and cell uptake mechanisms depend on the heterogeneous composition of the EV membrane. From a colloidal perspective, the EV membrane interacts with other biological interfaces via both specific and non-specific interactions, w
