Rostrocaudal patterning of the neural tube is a defining event in vertebrate brain development. This process is driven by morphogen gradients which specify the fate of neural progenitor cells, leading to the partitioning of the tube. Although this is extensively studied experimentally, an integrated view of the genetic circuitry is lacking. Here, we present a minimal gene regulatory model for rost
In this paper, we consider the flow and heat transfer behaviour of turbulent upward and downward flows of supercritical n-decane, in order to reveal the features of heat transfer deterioration (HTD) that would be expected in relevant active regenerative cooling systems for scramjet engines. Specific focus is placed on key velocity-field features that appear in these flows. Following the validation
Background: The rising prevalence of dementia represents an important public health issue. There is currently no available cure for dementia disorders, only symptom-relieving therapies which can be either pharmacological or non-pharmacological. The number of non-pharmacological interventions for patients with dementia disorders and their caregivers have been increasing in recent years without much
INTRODUCTION: Previous gene expression analysis have identified fetal hemoglobin (HbF) as a plausible etiological factor in preeclampsia. Free hemoglobin and its degradation products, e.g. heme, are known to cause oxidative stress, tissue damage, and vaso-constriction, typical findings in preeclampsia.OBJECTIVE: To study alpha-1-microglobulin (A1M), an endogenous radical scavenger and heme-binder,
Purpose: Today’s chemical society use and emit an enormous number of different, potentially ecotoxic, chemicals to the environment. The vast majority of substances do not have characterisation factors describing their ecotoxicity potential. A first stage, high throughput, screening tool is needed for prioritisation of which substances need further measures. Methods: USEtox characterisation factors
Background: Caldicellulosiruptor saccharolyticus is an attractive hydrogen producer suitable for growth on various lignocellulosic substrates. The aim of this study was to quantify uptake of pentose and hexose monosaccharides in anindustrial substrate and to present a kinetic growth model of C. saccharolyticus that includes sugar uptake on defined and industrial media. The model is based on Monod
The sky view factor (SVF) is an important radiometric parameter for assessing the canopy energy budget of urban areas. There are several methods to determine the SVF observationally. The most common is taking a photo with a digital camera equipped with a fish-eye lens and then converting ratio of sky area to canopy area into SVF. However, most urban canopy models use this variable as derived from
Aims: We tested the association between alcohol use disorder (AUD) and divorce; estimated the genetic and environmental influences on divorce; estimated how much genetic and environmental influences accounted for covariance between AUD and divorce; and estimated latent genetic and environmental correlations between AUD and divorce. We tested sex differences in these effects. Design: We identified
Many individuals with prediabetes, as presently defined, will progress to diabetes (T2D) despite the considerable benefit of lifestyle modification. Therefore, it is paramount to screen individuals at increased risk with a more sensitive method capable of identifying prediabetes at an even earlier time point in the lengthy trajectory to T2D. This petition reviews findings demonstrating that the 1-
Summary: The aim of the study was to evaluate the feasibility and most efficient way of offering middle-aged Swedish women a primary fracture screening program via a questionnaire. Two out of five invited women returned the FRAX questionnaire and those contacted directly by mail were most prone to respond. Purpose: Osteoporosis and its associated fractures are increasing, and this study aims to ex
Alveolar bone loss is a common problem that affects dental implant placement. A barrier between the bone substitute and gingiva that can prevent fibro-tissue ingrowth, bacterial infection and induce bone formation is a key factor in improving the success of alveolar ridge reconstruction. This study aims to develop a bioactive collagen barrier material for guided bone regeneration, that is coupled
Background Whole-genome sequencing (WGS) of heart transplant recipient- and donor-derived cardiac biopsies may facilitate organ matching, graft failure prediction, and immunotolerance research. The objective of this study was to determine the feasibility of WGS based on formalin-fixed paraffin-embedded endomyocardial biopsies. Methods and results The study included serial donor- and recipient samp
Background: Genome-wide association studies (GWAS) have identified >50 single nucleotide polymorphisms (SNP) in association with estimated glomerular filtration rate (eGFR) and chronic kidney disease (CKD) but little is known about whether the combination of these SNPs may aid in prediction of future incidence of CKD in the population. Methods: We included 2301 participants with baseline eGFR ≥60
Background: Mechanisms related to the influence of diet on the development of cardiovascular disease are not entirely understood, and protein biomarkers may help to understand these pathways. Studies of biomarkers identified with multiplex proteomic methods and dietary patterns are largely lacking. Methods and Results: Dietary patterns were generated through principal component analysis in 2 popul
Abstract Objective. Prostate cancer antigen 3 in urine (uPCA3) has been shown to perform better than total prostate-specific antigen in serum (tPSA) to predict prostate cancer (PCa) detection. The aim of this study was to validate the diagnostic precision of uPCA3 in a mixed set of patients with no previous history of PCa, including patients with previous negative biopsies. Material and methods. T
BACKGROUND: Sarcoidosis has been reported to be associated with an increased risk of cancer; however, little information is available about the prognosis for sarcoidosis patients diagnosed with cancer. PATIENTS AND METHODS: A population-based cohort of sarcoidosis patients was identified from Swedish registers. Cause-specific and overall hazard ratios (HRs) were estimated by using Cox regression m
There have been a few reports of successful lung transplantation (LTx) in patients with SARS-CoV-2-induced acute respiratory distress syndrome (ARDS); however, all reports were with rather short follow-up. Here we present a 62-year-old man without prior lung diseases. Following SARS-CoV-2-induced ARDS and 6 months of extracorporeal membrane oxygenation, he underwent LTx. 3 months post-transplantat
