Gene transfer by interspecific hybridization in bryophytes

The role of hybridization in evolution has been debated for more than a century regarding bryophytes (mosses, liverworts, and hornworts) as well as most other organisms. Bryophytes have haplodiplontic life cycles with a dominant haploid generation. Hybridization in bryophytes involves fusion of gametes produced by haploid parental gametophytes of different species. The hybrid is thus the short-livThe role of hybridization in evolution has been debated for more than a century regarding bryophytes (mosses, liverworts, and hornworts) as well as most other organisms.

Ömsesidighet i framtidens praktiknära språkklassrumsforskning : ASLA-symposiets panelsamtal med forskare, lärare och elever

Under ASLA-symposiet hölls för första gången ett panelsamtal om forskningsbehov i språkämnena där lärare, språkforskare och gymnasieelever deltog. I detta kapitel situerar vi idén med panelsamtalet i studier av lärares roll i och för den praktiknära skolforskningen. Vi redogör för några modeller för samverkan mellan lärare och forskare och diskuterar identifierade framgångsfaktorer i praktiknära f

Clinical and Biochemical Aspects of the Emergency Management of Traumatic Brain Injury

Populärvetenskaplig sammanfattning(Summary in Swedish)Hjärnskada som orsakas av olyckor är en vanlig orsak till både handikapp och död bland vuxna. För 30 år sedan var majoriteten av de som drabbades yngre eller väldigt gamla. Ålderssammansättningen av de som drabbas har skiftat under de senaste 20 åren och nu är det ungefär lika vanligt i alla åldrar. Dessutom är den vanligaste olycksorsaken inte

Preterm intraventricular cerebral hemorrhage: role of cell-free hemoglobin

Cerebral intraventricular hemorrhage in preterm infants continues to be a major clinical problem associated with neurodevelopmental abnormalities manifested by cognitive, behavioral, attentional, social and motor deficits. Hypothesis and aims: The central thesis is that the cytotoxicity of extravasated blood and of consequently released cell-free hemoglobin(Hb) is pivotal for the pathophysiologica

The tumultuous transition from modernism to postmodernism. Fictional representations

What is an intellectual about in this context? It seems that the traits of British provincial intellectuals in the 50s are snobbery, social sophistication and hierarchical mentality. Their productivity consists of correct, but mediocre articles, and once in a while books, especially compilations. These are the pillars of a decrepit modernism, figment of social respectability, but not of originalit

Five-Second Squeeze Testing in 333 Professional and Semiprofessional Male Ice Hockey Players: How Are Hip and Groin Symptoms, Strength, and Sporting Function Related?

Background: Hip and groin problems are just as common in ice hockey as they are in soccer. The 5-second squeeze test (5SST) is a valid indicator of hip- and groin-related sporting function (self-reported function) in soccer and is suggested to be interpreted according to a “traffic light” approach in guiding the early identification and management of affected players. It is currently unknown how t

Expression, activity and localization of lysosomal sulfatases in Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) is a leading cause of death world-wide. Recently, we showed that COPD is associated with gene polymorphisms in SUMF1, a master regulator of sulfatases. Sulfatases are involved in extracellular matrix remodeling and activated by SUMF1, but their role in the lung is poorly described. We aimed to examine how sulfatases are affected in the airways of patien

Is one carbon price enough? Assessing the effects of payment vehicle choice on willingness to pay in Sweden

Existing knowledge suggests that people's willingness to pay (WTP) for climate change mitigation depends not only on personal characteristics but also on the payment vehicle (PV) that is used to elicit WTP. The aim of this research is to investigate policy-relevant differences in WTP between different PVs to support the design of carbon pricing mechanisms. The novelty of this contingent valuation

Phenology of the avian spring migratory passage in Europe and North America : Asymmetric advancement in time and increase in duration

Climate change has been shown to shift the seasonal timing (i.e. phenology) and distribution of species. The phenological effects of climate change on living organisms have often been tested using first occurrence dates, which may be uninformative and biased. More rarely investigated is how different phases of a phenological sequence (e.g. beginning, central tendency and end) or its duration have

Beyond Democracy-Dictatorship Measures : A New Framework Capturing Executive Bases of Power, 1789-2016

We attempt to integrate the literatures on authoritarian regime types and democratic forms of government. We propose a theoretical framework of five dimensions of executive appointment and dismissal that can be applied in both more democratic and more authoritarian regimes: the hereditary, military, ruling party, direct election, and confidence dimensions, respectively. Relying on the Varieties of

Uncomplicated urinary tract infections in Swedish primary care; Etiology, resistance and treatment

Background: Uncomplicated urinary tract infection (uUTI) is common and a majority of patients are prescribed antibiotics. There is little knowledge about antibiotic resistance in urine samples from patients with uUTI in primary health care (PHC). The aim was to describe antibiotic treatment, bacterial findings, the prevalence of resistant E.coli and factors associated with antibiotic resistance. T

Improved long-term survival with home hemodialysis compared with institutional hemodialysis and peritoneal dialysis : A matched cohort study

Background: The survival rate for dialysis patients is poor. Previous studies have shown improved survival with home hemodialysis (HHD), but this could be due to patient selection, since HHD patients tend to be younger and healthier. The aim of the present study is to analyse the long-term effects of HHD on patient survival and on subsequent renal transplantation, compared with institutional hemod

Association of recurrent venous thromboembolism and circulating microRNAs

Background: Patients with unprovoked first venous thromboembolism (VTE) are at a high risk of recurrence. Although circulating microRNAs (miRNAs) have been found to be associated with VTE and are markers of hypercoagulability, this study is the first to examine whether circulating miRNAs are associated with the risk of VTE recurrence. Results: A nested case-control study design was used where plas
