Wolbachia-driven selective sweep in a range expanding insect species

Background: Evolutionary processes can cause strong spatial genetic signatures, such as local loss of genetic diversity, or conflicting histories from mitochondrial versus nuclear markers. Investigating these genetic patterns is important, as they may reveal obscured processes and players. The maternally inherited bacterium Wolbachia is among the most widespread symbionts in insects. Wolbachia typ

Taurine and N-acetyl-cysteine supplementation prevents memory impairment in high-fat diet-fed female mice

Background: The risk to develop memory impairment in has been widely investigated in type 2 diabetes (T2D). There are several mechanisms proposed for T2D-associated cognitive impairment, such as brain insulin resistance, synaptic dysfunction, inflammation, gliosis, or disruption of neuron-astrocyte interactions (Garcia-Serrano & Duarte, 2020). On the other hand, supplementation with the antiox

The Vbeta13 T Cell Receptor Monoclonal Antibody Reduces Hyaluronan and CD68+, CD3+, and CD8+ Cell Infiltrations to Delay Diabetes in Congenic BB DRLyp/Lyp Rats

The depleting Vβ13a T cell receptor monoclonal antibody (mAb) 17D5 prevents both induced and spontaneous autoimmune diabetes in BB rats. Here it was tested in congenic DRLyp/Lyp rats, all of which spontaneously developed diabetes. Starting at 40 days of age, rats were injected once weekly with either saline, His42 Vβ16 mAb, or 17D5 mAb and monitored for hyperglycemia. Diabetes occurred in 100% (n

AMP-activated protein kinase in adipose tissue

The AMP-activated protein kinase (AMPK) is a ubiquitously expressed kinase, which is activated in response to depletion of cellularenergy levels. Once active, it functions to alter cellular metabolism in a way that leads to restoration of energy levels. Therefore,AMPK is described as the key regulator of cellular energy homeostasis. Over the past years, AMPK activation has gained increasingattenti

Association of incident fragility fractures in patients hospitalised due to unexplained syncope and orthostatic hypotension

Background Fragility fractures are caused by low-energy insults such as falls from standing height or less and pose a growing health challenge as their incidence rises with increasing age. Impaired orthostatic blood pressure response and a number of cardiovascular biomarkers have been previously identified as risk factors for fractures. It is likely that severe episodes of syncope and orthostatic

A communicative approach to resilience in urban regions

The Covid-19 pandemic has fundamentally changed travel patterns to and in urban regions. Destinations have seen a dramatic shift from overtourism to undertourism. This research explores how the pandemic has reconceptualised the relationship between the urban and rural. In particular this paper discusses the relationship between media narratives and tourism flows, and the implications for resilienc

Visual and non-visual agency in transformation of urban space. : On the semiotics of spatial governance

When semiotics of architectural space turns from an interest in the visual revelation of a space “hidden” behind city plans or types of building facades, and focuses more on the socio-logical or narrato-logical interaction between humans, rules and matter, the subject of investigation (i.e. space) consequently turns more corporeal, more situation-based, and more political. In his philosophy of spa

Patients and Professionals as Partners in Hypertension Care : Qualitative Substudy of a Randomized Controlled Trial Using an Interactive Web-Based System Via Mobile Phone

BACKGROUND: The use of technology has the potential to support the patient´s active participation regarding treatment of hypertension. This might lead to changes in the roles of the patient and health care professional and affect the partnership between them.OBJECTIVE: The aim of this qualitative study was to explore the partnership between patients and health care professionals and the roles of p

Method comparison of indirect assessments of understory leaf area index (LAIu) : A case study across the extended network of ICOS forest ecosystem sites in Europe

Leaf area index (LAI) is a key ecological indicator for describing the structure of canopies and for modelling energy exchange between atmosphere and biosphere. While LAI of the forest overstory can be accurately assessed over large spatial scales via remote sensing, LAI of the forest understory (LAIu) is still largely ignored in ecological studies and ecosystem modelling due to the fact that it i

Hospital Admission Rate, Cumulative Hospitalized Days, and Time to Admission Among Older Persons With Substance Use and Psychiatric Conditions

Background: Substance use among older persons occurs with medical and psychiatric comorbidities. This study examined the associations of substance use disorder (SUD), psychiatric, and dual diagnoses with 12-month cumulative hospitalized days, hospital admission rate and number of days to first hospitalization.Methods: The cohort of 3,624 individuals (28.2% women) aged 50 years or older was assesse

Translation and implementation of nature-based solutions in cities : Experimentation, learning and knowledge production

As part of current efforts to work towards sustainable development, find solutions to curb greenhouse gas emissions, and adapt cities to the effects of climate change, such as floods and extreme heat, there are high hopes that nature-based solutions (NBS) can support the transformation needed. Based on the knowledge that implementation and governance of urban NBS is still emerging and constrained

Penile Intraepithelial Neoplasia and Penile Cancer. Risk Factors and Treatment.

AbstractPenile cancer and its precursor, penile intraepithelial neoplasia (PeIN), are rare malignancies. Data on risk factors, incidence, and treatment of PeIN is scarce. The prevalence of human papillomavirus (HPV) varies substantially between studies of penile cancer.The aims of this thesis were to explore the incidence, risk factors and treatment of PeIN; to analyse the prevalence of HPV and sk

Components of a healthy diet and different types of physical activity and risk of atherothrombotic ischemic stroke : A prospective cohort study

Background: Diet and physical activity (PA) are modifiable risk factors thought to influence the risk of ischemic stroke (IS). However, few studies have examined their effect on different subtypes of IS. Aim: To examine components of overall diet quality and different types of PA in relation to the risk of atherothrombotic IS (aIS). Materials and methods: The study population included 23,797 parti

Early Versus Delayed Non-Vitamin K Antagonist Oral Anticoagulant Therapy after Acute Ischemic Stroke in Atrial Fibrillation (TIMING) : A Registry-Based Randomized Controlled Noninferiority Study

Background: There are no evidence-based recommendations on the optimal time point to initiate non-vitamin K antagonist oral anticoagulants (NOACs) after acute ischemic stroke in patients with atrial fibrillation. We aimed to investigate the efficacy and safety of early versus delayed initiation of NOAC in these patients. Methods: TIMING (Timing of Oral Anticoagulant Therapy in Acute Ischemic Strok

Can frailty in conjunction with FRAX identify additional women at risk of fracture - a longitudinal cohort study of community dwelling older women

Background: Fracture risk assessment is still far from perfect within the geriatric population. The overall aim of this study is to better identify older women at risk for fractures, using a quantitative measure of frailty in conjunction with the web-based Fracture Risk Assessment Tool (FRAX®). Methods: This study was performed in the Osteoporosis Risk Assessment (OPRA) cohort of n = 1023, 75-year

Relation between perinatal outcome and gestational duration in term primiparous pregnancies stratified by body mass index

Introduction: There is growing evidence that induction of labor at 41 completed weeks improves neonatal outcome, at least among primiparous women. This study was performed to investigate whether maternal body mass index (BMI) should be considered when deciding on timing of intervention in term pregnancies. Material and methods: The study design was a historical cohort study using data from the Swe

Peripheral Oxygen Saturation Facilitates Assessment of Respiratory Dysfunction in the Sequential Organ Failure Assessment Score with Implications for the Sepsis-3 Criteria

OBJECTIVES: Sequential Organ Failure Assessment score is the basis of the Sepsis-3 criteria and requires arterial blood gas analysis to assess respiratory function. Peripheral oxygen saturation is a noninvasive alternative but is not included in neither Sequential Organ Failure Assessment score nor Sepsis-3. We aimed to assess the association between worst peripheral oxygen saturation during onset

Farm to furan derivatives : Fractionation of agricultural residues and transformation of sugars to chemical building blocks

The transition of industrial production from petrochemistry to a more sustainable economy requires the use of carbon neutral, renewable feedstock, which does not compete with food and feed supplies – by-products of farming and agro-food industry offer this possibility. With a limited range of low-value applications today coupled with the need for maximal utilisation of resources, the by-products o

Complications in emergency department patients with acute coronary syndrome with contemporary care

INTRODUCTION: With the implementation of early reperfusion therapy, the number of complications in patients with acute coronary syndrome (ACS) has diminished significantly. However, ACS patients are still routinely admitted to units with high-level monitoring such as the coronary or intensive care unit (CCU/ICU). The cost of these admissions is high and there is often a shortage of beds. The aim o
