Nowadays, is becoming increasingly frequent holding events in outdoor environments, involving a large number of people, even though these spaces were not designed from a safe prospective, in the way that safety is defined today. In such events, high density conditions is an ongoing issue, as the evacuation becomes very complex, due to the space design and the interaction among the pedestrians. It
Att behandla tumörsjukdomar genom injektion av radioaktiva läkemedel är en behandlingsteknik kallad radionuklidterapi. Det radioaktiva läkemedlet består av en radioaktiv isotop, fäst på en målsökande bärarmolekyl, specifik för den vävnad vari man önskar att läkemedlet skall ansamlas. Då den radioaktiva isotopen sönderfaller sänds joniserande strålning ut; strålning med förmågan att jonisera molekyIntroduction: There is a need of reassessment of radiation absorbed dose specification in nuclear medicine, taking the non-uniformities in the distribution of radioactivity into account. This is especially important in radionuclide therapies where very high activities are administered and the radionuclides emit alpha particles, beta particles or low-energy electron and will require absorbed dose c
There is an urgent need for accurate and validated methods to measure plasma phosphorylated tau (p-Tau) biomarkers in Alzheimer’s disease (AD). In this study, we compared the performance of new commercially available plasma p-Tau217 assay developed by ALZpath to other established p-Tau assays in an autopsy-confirmed sample. We included 72 participants from the Arizona Study of Aging and Neurodegen
Background: Disorders affecting the nervous system are diverse and include neurodevelopmental disorders, late-life neurodegeneration, and newly emergent conditions, such as cognitive impairment following COVID-19. Previous publications from the Global Burden of Disease, Injuries, and Risk Factor Study estimated the burden of 15 neurological conditions in 2015 and 2016, but these analyses did not i
Before performing 177Lu-DOTATATE therapy for neuroendocrine tumors, somatostatin receptor (SSTR) PET imaging is currently used to confirm sufficient tumor SSTR expression, but it also has potential to be used to personalize treatment by predicting absorbed doses to critical organs. This study aims to validate the predictive capability of SSTR PET in anticipating renal absorbed dose in the first cy
Evidence from neuropathological cohorts indicates that a CSF α-synuclein (α-syn) seed amplification assay (SAA) might provide quantitative kinetic parameters correlating with α-syn pathology burden in patients with Lewy body disease (LBD). Studies are needed to assess their longitudinal trend during the presymptomatic and clinical disease phases and their correlation with measures of disease progr
Background Pulmonary nodules (PNs) are clinically challenging because differentiation between benign and malignant PNs is not possible at CT detection; recurring CT examinations and invasive procedures are often required in PN follow-up. Purpose To investigate PN prevalence in a middle-aged population and the risk factors associated with these nodules. Materials and Methods In this secondary analy
Background: In Alzheimer’s disease (AD), the associations between tau pathology and brain atrophy and cognitive decline are well established, but imperfect. We investigate whether cerebrospinal fluid (CSF) biomarkers of biological processes (vascular, synaptic, and axonal integrity, neuroinflammation, neurotrophic factors) explain the disconnection between tau pathology and brain atrophy (brain re
Background: Up-to-date estimates of stroke burden and attributable risks and their trends at global, regional, and national levels are essential for evidence-based health care, prevention, and resource allocation planning. We aimed to provide such estimates for the period 1990–2021. Methods: We estimated incidence, prevalence, death, and disability-adjusted life-year (DALY) counts and age-standard
IntroductionYoung migrants are increasingly recognised as being particularly vulnerable to sexual violence. This vulnerability is largely structural, due to the different laws and policies impacting their access to rights and services. Post-structural approaches to policy argue that policies are not responses to existing problems, but rather that social issues are constructed through policy. They
Background: Cataracts are the leading cause of reversible blindness globally, disproportionately affecting populations in low- and middle-income countries. In Ethiopia, cataracts remain a significant public health concern. Despite the effectiveness of cataract surgery in restoring vision, information on recovery time and its predictors remain limited. The aim of this study was to assess time to re
Subsolidus phase relations have been determined for the BaO:TiO2:Ta2O5 system by X-ray diffraction analysis of ~100 specimens prepared in air at temperatures near but below the solidus (1275 °C to 1500 °C). For the BaO:Ta2O5 subsystem, the formation of all three polymorphs of BaTa2O6 (orthorhombic, tetragonal, and hexagonal) was confirmed. The present study found no stable phases forming between B
Mineralogical and geochemical studies of the non-marine Permian–Triassic (P–Tr) boundary across two stratigraphically wellconstrained sections (Commando Drift Dam and Wapadsberg, Eastern Cape Province) in the southern Karoo Basin, South Africa, have been undertaken to provide further input on the cause of this mass extinction event, and so has a sedimentological and geochemical evaluation of a thi
Purpose: To determine progression factors at the end of the Early Manifest Glaucoma Trial (EMGT) based on all EMGT patients and evaluate separately patients with higher and lower baseline intraocular pressure (IOP; median split). Design: Cohort of clinical trial participants. Participants: Patients with early open-angle glaucoma randomized to argon laser trabeculoplasty plus betaxolol (n = 129) or
IMPORTANCE: The number of patients prescribed long-term opioids and benzodiazepines and complications from their long-term use have increased. Information regarding the perioperative outcomes of patients prescribed these medications before surgery is limited.OBJECTIVE: To determine whether patients prescribed opioids and/or benzodiazepines within 6 months preoperatively would have greater short- a
Activation-induced cytidine deaminase (AID) is an enzyme and key component of both 15 class-switch recombination and somatic hypermutation, two mechanisms used by activated B 16 cells to diversify their antigen repertoire, as it catalyzes the deamination of deoxycytidines turning 17 them into deoxyuridines, introducing mutations in immunoglobulin genes. AID, however, can also 18 target enhancer re
Background There is currently no standardized process for long-term follow-up care. As a result, management of post-stroke care varies greatly, and the needs of stroke survivors are not fully addressed. The Post Stroke Checklist was developed by the Global Stroke Community Advisory Panel as a means of standardizing long-term stroke care. Since its development, the Post Stroke Checklist has gained
When mouse hippocampal neuronal cultures, 2-3 weeks in vitro, were transiently exposed to combined glucose and oxygen deprivation (100% argon, 5% CO2, in glucose-free medium) for 90 min, extensive neuronal degeneration had occurred after 24 h of reoxygenation. When these cultures were preincubated with cyclosporin A, a calcineurin inhibitor and a blocker of the mitochondrial permeability transitio
Abstract: The changes in the levels of tyrosine‐phosphorylated proteins in the cytosolic fraction of the rat hippocampus subjected to severe hypoglycemia were analyzed. A marked increase in tyrosine phosphorylation of a 43‐kDa protein was observed at 30 min of isoelectric EEG and 30 min and 1 h of recovery. Immunostaining of the same blot with antibody against mitogen‐activated protein (MAP) kinas
Neuronal protein synthesis is severely depressed following stress such as heat-shock, hypoxia, and hypoglycemia. Following reversible cerebral ischemia, protein synthesis is transiently inhibited in ischemia-resistant areas, but persistently depressed in vulnerable brain regions. Eukaryotic initiation factor 2 (elF-2) activity, that is, the formation of the ternary complex elF-2 · GTP · initiator
