Impact of Cardiovascular Neurohormones on Onset of Vasovagal Syncope Induced by Head-up Tilt.

BackgroundVasovagal reflex is the most common form of syncope, but the pathophysiological mechanisms that initiate the reflex are not well understood. We aimed to study supine and early orthostatic levels of the neurohormones involved in control of circulatory homeostasis in relation to the onset of tilt‐induced vasovagal syncope (VVS).Methods and ResultsA total of 827 patients who were investigat

Expression levels of enzymes generating NO and CO in islets of murine and human diabetes

The possible implication of the gasotransmitters NO and CO for the development of diabetes remains unresolved. Our previous investigations in rodents suggested NO being inhibitory, and CO stimulatory, to glucose-stimulated insulin secretion (GSIS). Here we studied the possible role of these gasotransmitters in both murine and human type 2 diabetes (T2D) by mapping the expression pattern of neural

Parental help-seeking behaviour for, and care of, a sick or injured child during the COVID-19 pandemic: a European online survey

BackgroundGlobally, the COVID-19 pandemic had a huge impact on patients and healthcare systems. A decline in paediatric visits to healthcare settings was observed, which might have been due to lower incidence of injury and infectious illness, changes in healthcare services and parental concern. The aim of our study was to examine parental experiences of help-seeking for, and care of, a sick or inj

Engineered allele substitution at PPARGC1A rs8192678 alters human white adipocyte differentiation, lipogenesis, and PGC-1α content and turnover

Aims/hypothesisPPARGC1A encodes peroxisome proliferator-activated receptor γ coactivator 1-α (PGC-1α), a central regulator of energy metabolism and mitochondrial function. A common polymorphism in PPARGC1A (rs8192678, C/T, Gly482Ser) has been associated with obesity and related metabolic disorders, but no published functional studies have investigated direct allele-specific effects in adipocyte bi

Exploring biomarkers associated with deteriorating vascular health using a targeted proteomics chip : The SABPA study

ABSTRACT: In this observational study, by the use of a multiplex proteomic platform, we aimed to explore associations between 92 targeted proteins involved in cardiovascular disease and/or inflammation, and phenotypes of deteriorating vascular health, with regards to ethnicity.Proteomic profiling (92 proteins) was carried out in 362 participants from the Sympathetic activity and Ambulatory Blood P

Properties and emission factors of cloud condensation nuclei from biomass cookstoves - Observations of a strong dependency on potassium content in the fuel

Residential biomass combustion is a significant source of aerosol particles on regional and global scales influencing climate and human health. The main objective of the current study was to investigate the properties of cloud condensation nuclei (CCN) emitted from biomass burning of solid fuels in different cookstoves mostly of relevance to sub- Saharan east Africa. The traditional three-stone fi

Dangerous Proteins and Where to Find Them- Structural and functional studies of bacterial and viral proteins interacting with human immune receptors in health and disease

Bacteria and viruses are threats to human that evolved strategies to bypass the immune system and can cause massive damage. Understanding these strategies and elucidating pathogen interacting partners within the human immune system will pave the way for discovery of new medicines and increase human well-being. Superantigens (SAgs) are toxins that induce a massive immune response, causing sever dis

Plasma Proneurotensin and Prediction of Cause-Specific Mortality in a Middle-aged Cohort During Long-term Follow-up

CONTEXT: Neurotensin is associated with cardiometabolic diseases but its role with mortality risk in humans is unknown.OBJECTIVE: This work aims to examine the prediction of proneurotensin (Pro-NT) with respect to total and cause-specific mortality in a middle-aged cohort.METHODS: In the population-based middle-aged cohort (n = 4632; mean age, 57 years) of the Malmö Diet and Cancer Study, Pro-NT w

St Gallen 2019 guidelines understage the axilla in lobular breast cancer : a population-based study

BACKGROUND: The St Gallen 2019 guidelines for primary therapy of early breast cancer recommend omission of completion axillary lymph node dissection (cALND), regardless of histological type, in patients with one or two sentinel lymph node (SLN) metastases. Concurrently, adjuvant chemotherapy is endorsed for luminal A-like disease with four or more axillary lymph node (ALN) metastases. The aim of t

Distinct contributions of metabolic dysfunction and genetic risk factors in the pathogenesis of non-alcoholic fatty liver disease

Background & Aims: There is substantial inter-individual variability in the risk of non-alcoholic fatty liver disease (NAFLD). Part of which is explained by insulin resistance (IR) (‘MetComp’) and part by common modifiers of genetic risk (‘GenComp’). We examined how IR on the one hand and genetic risk on the other contribute to the pathogenesis of NAFLD. Methods: We studied 846 individuals: 49

Differences in accumulation of polycyclic aromatic compounds (PACs) among eleven broadleaved and conifer tree species

PACs (polycylic aromatic compounds) are air pollutants formed in incomplete combustion, e.g., in vehicle engines. Vegetation can potentially remove substantial amounts and act as bioindicators of these pollutants. Increased knowledge of the pollutant removal efficiencies of different tree species is essential for understanding the potential benefits trees can provide urban residents. We investigat

Using phosphoglucose isomerase-deficient (pgi1Δ) Saccharomyces cerevisiae to map the impact of sugar phosphate levels on d-glucose and d-xylose sensing

Background: Despite decades of engineering efforts, recombinant Saccharomyces cerevisiae are still less efficient at converting d-xylose sugar to ethanol compared to the preferred sugar d-glucose. Using GFP-based biosensors reporting for the three main sugar sensing routes, we recently demonstrated that the sensing response to high concentrations of d-xylose is similar to the response seen on low

High Risk of Low Anterior Resection Syndrome in Long-term Follow-up After Anastomotic Leakage in Anterior Resection for Rectal Cancer

BACKGROUND: Low anterior resection syndrome is common after sphincter-sparing surgery, but it is unclear to what extent anastomotic leakage after anterior resection contributes to this condition. OBJECTIVE: The aim of this study is to assess the long-term effect of anastomotic leakage on the occurrence of major low anterior resection syndrome. DESIGN: This is a retrospective observational cohort s

We present a novel high-resolution inverse modelling system ("FLEXVAR") based on FLEXPARTCOSMO back trajectories driven by COSMO meteorological fields at 7 km×7 km resolution over the European COSMO-7 domain and the four-dimensional variational (4DVAR) data assimilation technique. FLEXVAR is coupled offline with the global inverse modelling system TM5-4DVAR to provide background mole fractions ("b

Novel Subgroups of Type 2 Diabetes Display Different Epigenetic Patterns, Which Associate With Future Diabetic Complications

BACKGROUND: Type 2 diabetes (T2D) was recently reclassified into severe insulin deficient diabetes (SIDD), severe insulin resistant diabetes (SIRD), mild obesity-related diabetes (MOD), and mild age-related diabetes (MARD), which have different risk of complications. We explored whether DNA methylation differs between these subgroups and whether subgroup-unique methylation risk scores (MRSs) predi

Drought recorded by Ba/Ca in coastal benthic foraminifera

Increasing occurrences of extreme weather events, such as the 2018 drought over northern Europe, are a concerning issue under global climate change. High-resolution archives of natural hydroclimate proxies, such as rapidly accumulating sediments containing biogenic carbonates, offer the potential to investigate the frequency and mechanisms of such events in the past. Droughts alter the barium (Ba)
