Larval environmental conditions influence plasticity in resource use by adults in the burying beetle, Nicrophorus vespilloides

Recent studies have shown that intraspecific patterns of phenotypic plasticity can mirror patterns of evolutionary diversification among species. This appears to be the case in Nicrophorus beetles. Within species, body size is positively correlated with the size of carrion used to provision larvae and parental performance. Likewise, among species, variation in body size influences whether species

16S rRNA is a valuable tool in finding bacterial aetiology of community-acquired pleural empyema-a population-based observational study in South Sweden

BackgroundThe incidence of community-acquired pleural empyema is increasing. Knowledge of the bacterial aetiology is important in order to base recommendations on empirical antimicrobial treatment. The primary aim of the present study was to describe the bacterial aetiology of adult patients with culture proven and/or 16S rRNA-positive community-acquired pleural infection.MethodsWe performed a ret

Failing the formative phase : The global diffusion of nuclear power is limited by national markets

Understanding the role of technology characteristics and the context in the diffusion of new energy technologies is important for assessing feasibility of climate mitigation. We examine the historical adoption of nuclear power as a case of a complex large scale energy technology. We conduct an event history analysis of grid connections of first sizable commercial nuclear power reactors in 79 count

Second-line palliative chemotherapy, survival, and prognostic factors in patients with advanced pancreatic cancer

Introduction: Pancreatic cancer is a highly lethal disease with a close association between incidence and mortality. First-line (FL) palliative chemotherapy prolongs survival and alleviates cancer-related symptoms. However, the survival benefit of second-line (SL) treatment is uncertain, as studies fail to consistently show prolonged survival for any given SL treatment, and in the absence of progn

Modelling and controlling of polymer electrolyte fuel cell systems

This thesis focuses on the modelling and controlling of polymer electrolyte fuelcell (PEFC) systems. A system level dynamic PEFC model has been developedto test the system performance (output voltage, reactants gas partial pressures,and stack temperature) for different operating conditions. The simulation resultsare in good agreement with the experimental data, which indicates that thePEFC model i

Stromal and tumor cell responses to hypoxia and treatment within the glioma microenvironment

Glioblastoma is the most aggressive primary brain tumor in adults. Despite treatment, tumors invariably recur, and the recurring tumor is resistant to therapies. New approaches are needed for the successful treatment of glioblastoma patients.Tumors are not simply a compilation of molecularly and phenotypically identical neoplastic cells. Instead, the tumor-associated stroma is instrumental in supp

Risk of environmental transmission of norovirus infection from prior room occupants

BACKGROUND: Environmental contamination of norovirus (NoV) is believed to be a significant source for further transmission in hospitals.AIM: To investigate the risk of acquiring NoV in a cleaned room previously occupied by a patient with NoV infection. The risk of having a roommate with recent NoV infection was also assessed.METHODS: In a retrospective cohort, comprising 33,788 room stays at five

Post-outbreak serological screening for SARS-CoV-2 infection in healthcare workers at a Swedish University Hospital

BACKGROUND: Nosocomial outbreaks of coronavirus disease 2019 (COVID-19) can have devastating consequences from both a resource cost and patient healthcare perspective. Relying on reverse transcription-polymerase chain reaction (RT-PCR) for identifying infected individuals may result in missed cases. Screening for antibodies after an outbreak can help to find missed cases and better illuminate rout

Preparing for the next crisis: Lessons from the successful Swedish fiscal framework

Ever since the international financial crisis of 2007/08, Sweden stands out as a country with a prudent and sustainable national debt policy. Debt rises during recessions and crises only to fall back during times of growth. A low debt level before a major crisis allows Sweden to increase its public debt and support the economy during a crisis without risking a fiscal crisis. The strength of the Sw

Macroeconomic equilibriums, crises, and fiscal policy

Fiscal policy plays an important role in alleviating the costs of the crisis. However, recent experiences suggest that the public finances often are unprepared for a crisis. Deficits and debt levels prior to the crisis are commonly too high, limiting the government’s ability to support the economy through the crisis and the recovery phase. In this paper, I argue that theoretical macroeconomic modeMacroeconomic crises are common as well as economically, socially and politically costly. Fiscal policy plays an important role in alleviating the costs of the crisis. However, recent experiences suggest that the public finances are often unprepared for a crisis.

The assessment of disease progression in keratoconus and corneal crosslinking in thin corneae

Keratoconus generally manifests in adolescents, and can progress leading to severely impaired vision. The risk of progression is inversely correlated to age; thus younger patients are at higher risk than older ones. Progressive keratoconus can be halted by corneal crosslinking (CXL). The general indication for CXL is progressive keratoconus, although children are commonly treated with CXL upon dia

Differential DNA Methylation and Expression of miRNAs in Adipose Tissue From Twin Pairs Discordant for Type 2 Diabetes

The prevalence of type 2 diabetes (T2D) is increasing worldwide, but current treatments have limitations. miRNAs may play a key role in the development of T2D and can be targets for novel therapies. Here, we examined whether T2D is associated with altered expression and DNA methylation of miRNAs using adipose tissue from 14 monozygotic twin pairs discordant for T2D. Four members each of the miR-30

The role of African-Caribbean nannies in European households is a painful chapter in Caribbean history for many reasons. Ann M. Beaudhuy was a nanny in Christiansted, St. Croix in what was then the Danish West Indies and which is now the US Virgin Islands. In 1871 she wrote letters that have survived time, transfer and geographical displacement. They contain a rare, personal account of the life an
