Resolving the biological paradox of aneurysm formation in children with tuberous sclerosis complex

Aortic aneurysms are rare manifestations in children with tuberous sclerosis complex (TSC) with life threating implications. Although an association between TSC, aortic and other aneurysms has been recognized, mechanistic insights explaining the pathophysiology behind aneurysm development and genetic aberrations in TSC have so far been lacking. Here, we summarize existing knowledge on aneurysms in

Morphological and ultrastructural alterations of zebrafish (Danio rerio) spermatozoa after motility activation

Spermatozoa motility in freshwater and marine fish is mainly controlled by the difference in osmotic pressure. Specifically, zebrafish (Danio rerio) spermatozoa undergo hypoosmotic shock due to the decrease in extracellular potassium, which leads to membrane hyperpolarization and activation of flagellar motility. Previous studies have concluded that motility activation has a negative effect on the

Cardiovascular effects of intrauterine exposure to maternal HIV and antiretroviral therapy in Ethiopian infants followed from fetal life

Objective:To assess cardiovascular effects of in-utero HIV and antiretroviral treatment (ART) exposure on offspring of HIV-positive mothers in Ethiopia.Design:HIV-positive and HIV-negative pregnancies were identified from a prospective cohort of women recruited at their first antenatal care visit in Ethiopia, using a nested case-control design.Methods:Fetal standard ultrasound and echocardiography

Behavioral and Psychological Symptoms of Dementia in Different Dementia Disorders : A Large-Scale Study of 10,000 Individuals

Background: The majority of individuals with dementia will suffer from behavioral and psychological symptoms of dementia (BPSD). These symptoms contribute to functional impairment and caregiver burden. Objective: To characterize BPSD in Alzheimer's disease (AD), vascular dementia (VaD), mixed (Mixed) dementia, Parkinson's disease dementia (PDD), dementia with Lewy bodies (DLB), frontotemporal deme

Outcomes associated with higher relational continuity in the treatment of persons with asthma or chronic obstructive pulmonary disease : A systematic review

Background: Asthma and chronic obstructive pulmonary disease (COPD) are chronic conditions where relational continuity of care, as in regularly meeting the same health care provider, creates opportunities for monitoring and adjustment of treatment based on an individual's changing needs, potentially affecting quality of delivered care. The aim of this systematic review was to investigate the effec

Early menopause and weight loss are significant factors associated with risk of future fracture in middle-aged women

BACKGROUND: To identify factors related to reproductive history and weight change associated with first incident fracture in middle-aged women.METHODS: In total, 18,326 women from the Malmö Diet and Cancer study were included in this prospective population-based cohort study. Participants were included 1991-1996 and followed to 2016. Using data from the National Patient Registry, linked with every

Cystic fibrosis transmembrane regulator correction attenuates heart failure-induced lung inflammation

Heart failure (HF) affects 64 million people worldwide. Despite advancements in prevention and therapy, quality of life remains poor for many HF patients due to associated target organ damage. Pulmonary manifestations of HF are well-established. However, difficulties in the treatment of HF patients with chronic lung phenotypes remain as the underlying patho-mechanistic links are still incompletely

The Sky as Heterotopia in in Dickens, Gissing, and Woolf

Different aspects of the novel have changed at a different pace. If one compares modernist novels with those of a 100 years previously, not only is an inward turn noticeable but also an outward turn: the sky, for example, is much more present. This change does not, however, coincide with the Victorian-modernist divide but rather comes when the influence of romantic poetry reaches the novel. This c

Hur gemensamma är de gemensamma EU-reglerna? : Svensk asylrätt i europeiskt perspektiv

Every EU country must adapt its national regulations to the common EU and ECHR standards. There is, however, a certain discretion to apply the EU standards into national legislation. For those in need of protection, is Sweden more or less generous in comparison to the EU’s minimum rules?This study examines Swedish asylum legislation from a European perspective. Although EU Member States are bound

Striatal hand deformities in Parkinson's disease - hand surgical perspectives

BackgroundThe knowledge about striatal hand deformities (SHD) in Parkinson’s disease (PD), has recently increased but need more attention due to their early impact on dexterity. The focus of clinical studies has been on the staging of SHD severity and neurological features. However, a hand surgical perspective has not been considered.ObjectivesOur purpose was to examine SHD in patients with PD usi

Compound-internal anaphora : evidence from acceptability judgements on Italian argumental compounds

The particular properties of argumental compounds in Italian pose interesting theoretical challenges, and investigations of possible syntactic operations within this type of complex words have resulted in conflicting conclusions. Regarding compoundinternal anaphora, some researchers exclude the possibility that pronouns can refer to the non-head, while others do not. However, these findings have b

Framtidens historia

Binding Kinetics of Proteins at Immune-Cell Contacts

Protein-protein interactions are crucial in numerous cellular functions and biological processes that take place inside our body. It is therefore not surprising that these interactions also govern the response of our body´s defence mechanism, the so-called immune system, towards an infection. Understanding how proteins interact entails studying the binding affinity (strength) and the lifetime (dur

The (non) accuracy of mitochondrial genomes for family-level phylogenetics in Erebidae (Lepidoptera)

The use of molecular data to study the evolutionary history of organisms has revolutionized the field of systematics. Now with the appearance of high throughput sequencing (HTS) technologies, more and more genetic sequence data are available. One of the important sources of genetic data for phylogenetic analyses has been mitochondrial DNA. The limitations of mitochondrial DNA for the study of phyl
