In this study, laminar burning velocities (LBV) of ammonia in oxygen-enriched air (oxygen content ranging from 30 to 50 vol%) were investigated under various initial temperatures (298, 323, and 348 K) at a pressure of 1 atm, employing the heat flux method. Our measurements reveal substantial disparities with previously published data primarily obtained using the spherical flame method. The reliabi
Background: The prognostic benefit of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) in stable coronary artery disease (CAD) remains uncertain. Objectives: To evaluate long-term survival following CTO PCI compared with medical therapy (MT) using target trial emulation and a nationwide real-world registry. Methods: We included 7813 patients with stable CAD and a document
The 39.4% decline in numbers in the Northeast/Northwest European population of Bewick’s Swan Cygnus columbianus bewickii between 1995 (29,780 birds) and 2010 (18,057 birds) was of major conservation concern, alleviated by a partial recovery to 20,149 recorded in the January 2015 census. The most recent census, in January 2020, however found that the recovery was not sustained. The results describe
IntroductionSport-related concussion (SRC) is one of the most common and concerning injuries in team sports, with potential long-term effects on athlete health and performance. Linear head acceleration (LHA) and rotational head acceleration (RHA) are central biomechanical markers of brain loading during impact. Yet, the magnitude of these accelerations during SRC events remains poorly synthesized
North Sea-Progressive Myoclonus Epilepsy (NS-PME) is a progressive neurological disorder, initially only associated with the homozygous GOSR2 founder mutation (c.430G>T; p.Gly144Trp). Clinical symptoms include untreatable early-onset ataxia, cortical myoclonus and epilepsy. Recently, the spectrum of GOSR2 mutations and associated phenotypic variability has expanded. To improve care and to facilita
Background: Islet autoantibodies form the foundation for type 1 diabetes (T1D) diagnosis and staging, but heterogeneity exists in T1D development and presentation. We hypothesized that autoantibodies can identify heterogeneity before, at, and after T1D diagnosis, and in response to disease-modifying therapies. Methods: We systematically reviewed PubMed and EMBASE databases (6/14/2022) assessing 10
Background: The objective of this systematic review is to identify prognostic factors among women and their offspring affected by gestational diabetes mellitus (GDM), focusing on endpoints of cardiovascular disease (CVD) and type 2 diabetes (T2D) for women, and cardiometabolic profile for offspring. Methods: This review included studies published in English language from January 1st, 1990, through
Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of 0.18âà € ³ in the optical, making it an ideal instrument to search for gravitational lenses down to the limiting magnitude of 21. Nevertheless, the previous Gaia Data Releases are known to be incomplete for small angular separations such as thos
A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets. The search is performed using the Large Hadron Collider proton-proton collision data sample at a centre-of-mass energy of s = 13 TeV recorded by the ATLAS detector that correspo
Type 2 diabetes (T2D) is a heterogeneous disease that develops through diverse pathophysiological processes1,2 and molecular mechanisms that are often specific to cell type3,4. Here, to characterize the genetic contribution to these processes across ancestry groups, we aggregate genome-wide association study data from 2,535,601 individuals (39.7% not of European ancestry), including 428,452 cases
Introduction: A subgroup of severe Traumatic Brain Injury (TBI) patients, known as ultra-severe (us-TBI), is most commonly defined as a post-resuscitation Glasgow Coma Scale (GCS) of 3–5. There is uncertainty on whether these critically injured patients can benefit from neurosurgical intervention. Research question: The available evidence regarding the decision-making and outcome following managem
BACKGROUND: The COVID-19 pandemic has highlighted the importance of evidence-informed priority setting and situational analysis in pandemic preparedness and response. Health Technology Assessment (HTA) has been identified as an essential tool for evidence-informed decision-making in healthcare. However, the potential role of HTA in pandemic preparedness and response in Africa has yet to be explore
This paper addresses the question of whether the rise to power of right-wing populist parties has an impact on the political opportunity structures (POS) available for incumbent civil society organizations (CSOs). The elements of POS that are exposed to changes by the right-wing populist parties in power are those that are embedded in governance structures. In this paper we will focus in particula

BACKGROUND: The variable penetrance of breast cancer in BRCA1/2 mutation carriers suggests that other genetic or environmental factors modify breast cancer risk. Two genes of special interest are prohibitin (PHB) and methylene-tetrahydrofolate reductase (MTHFR), both of which are important either directly or indirectly in maintaining genomic integrity. METHODS: To evaluate the potential role of ge
OBJECTIVE: To report population-based clinical presentation and outcomes in patients with urosymphyseal fistula (USF) after pelvic radiotherapy (RT). PATIENTS AND METHODS: A retrospective chart review was performed in 33 consecutive patients diagnosed with suspicion of USF in a tertial referral center from 2014-2022 to ascertain information about diagnostic delay, clinical presentation, precipitat
This thesis examines how intelligent case evaluation systems participate in the everyday production, interpretation, and enforcement of judicial norms within Chinese judicial organizations. Drawing on a qualitative documentary analysis of central-level policy documents, a published technical patent, and operational reports from courts and procuratorates, the study traces how abstract expectations
IntroductionAlthough transcranial sonography (TCS) assessing hyperechogenic substantia nigra (SN+) as biomarker for Parkinsońs disease (PD) has been introduced elsewhere, the clinical relevance and accuracy in a Swedish population is still unknown.MethodsThis retrospective single-center study included 74 patients with predominantly early-stage parkinsonism at first visit who had been examined by T
