Post-IR IRSL dating the oldest (?) river terrace sediments in the Polish Outer Carpathians : Insights into the landscape evolution

Post-infrared infrared stimulated luminescence (post-IR IRSL or pIRIR) was applied to determine the age of the highest-elevated alluvial sediments in the Polish Outer Carpathians. These sediments are preserved on the western slope of the Dunajec River valley, and are located 150–155 m above the present-day river channel. So far, they have been interpreted as accumulated during the Praetiglian (2.5

”En blombukett av chefen, inget mer” : En uppföljning av studenter som tagit en magister eller masterexamen vid Socialhögskolan, Lunds universitet under perioden HT07-HT13.

Titeln på rapporten är ett svar av en socionom på frågan om hon har haft något stöd från arbetsgivaren under studietiden. Jag har under min tid som studierektor för masterprogrammet vid Socialhögskolan, Lunds universitet under perioden 2007 till 2014 ofta fått frågor kring nyttan av en magister eller masterexamen när det gäller yrkeslivet. Frågor som har varit besvärliga att direkt besvara och som

Aerosolization and recovery of viable murine norovirus in an experimental setup

Noroviruses are the major cause for viral acute gastroenteritis in the world. Despite the existing infection prevention strategies in hospitals, the disease continues to spread and causes extensive and numerous outbreaks. Hence, there is a need to investigate the possibility of airborne transmission of norovirus. In this study, we developed an experimental setup for studies on the infectivity of a

Kir3 channel blockade in the cerebellar cortex suppresses performance of classically conditioned Purkinje cell responses

In the eyeblink conditioning paradigm, cerebellar Purkinje cells learn to respond to the conditional stimulus with an adaptively timed pause in its spontaneous firing. Evidence suggests that the pause is elicited by glutamate released from parallel fibers and acting on metabotropic receptors (mGluR7) which initiates a delayed-onset suppression of firing. We suggested that G protein activation of h

Light intensity regulates flower visitation in Neotropical nocturnal bees

The foraging activity of diurnal bees often relies on flower availability, light intensity and temperature. We do not know how nocturnal bees, which fly at night and twilight, cope with these factors, especially as light levels vary considerably from night to day and from night to night due to moon phase and cloud cover. Given that bee apposition compound eyes function at their limits in dim light

Diagnostic potential of circulating cell-free nuclear and mitochondrial DNA for several cancer types and nonmalignant diseases : A study on suspected cancer patients

Circulating cell-free nuclear DNA (nDNA) has been implicated in individual cancer types with a diagnostic value; however, the role of cell-free mitochondrial DNA (mtDNA) in cancers is controversial. We aimed to investigate and compare the diagnostic potential of both nDNA and mtDNA for multiple cancers and to investigate their ability to distinguish multiple cancers from healthy controls and from

The transfer of clinical prediction models for early trauma care had uncertain effects on mistriage

Objectives: This study aimed to assess how transfers of clinical prediction models for early trauma care between different care contexts within a single health system affected mistriage rates. Study Design and Setting: Patients aged 15 years or older, registered between 2011 and 2016 in the Swedish national trauma registry, SweTrau, were included. Three data set groups were created: high- and low-

Azure-winged magpies’ decisions to share food are contingent on the presence or absence of food for the recipient

Helping others is a key feature of human behavior. However, recent studies render this feature not uniquely human, and describe discoveries of prosocial behavior in non-human primates, other social mammals, and most recently in some bird species. Nevertheless, the cognitive underpinnings of this prosociality; i.e., whether animals take others’ need for help into account, often remain obscured. In

Centimeter-long III-Nitride nanowires and continuous-wave pumped lasing enabled by graphically epitaxial lift-off

It remains a big challenge to elongate one-dimensional (1D) semiconductor nanowires (NWs), which can be attractive platforms for miniaturizing and/or integrating macroscopic devices, into centimeter-scale length. Herein, we report the innovative preparation of single-crystalline III-nitride NWs, with unprecedented length above 2 cm and the aspect ratio above 6000, by graphically epitaxial lifting-

Unique signatures of stress-induced senescent human astrocytes

Senescence was recently linked to neurodegeneration and astrocytes are one of the major cell types to turn senescent under neurodegenerative conditions. Senescent astrocytes were detected in Parkinson's disease (PD) patients' brains besides reactive astrocytes, yet the difference between senescent and reactive astrocytes is unclear. We aimed to characterize senescent astrocytes in comparison to re

From boiling to frozen? The rise and fall of international tourism to iceland in the era of overtourism

Overtourism has emerged as a common concept to describe the perceived negative impacts that large numbers of tourists can have on destinations. Iceland is one of the destinations which has been most associated with the concept of overtourism. Tourism in Iceland grew rapidly from 2010 to 2019, much higher than in most other countries, with Iceland reaching a ranking as high as thirteenth on a list

Fetal/neonatal alloimmune thrombocytopenia : A systematic review of impact of HLA-DRB3∗01:01 on fetal/neonatal outcome

The most common, severe cases of fetal and neonatal alloimmune thrombocytopenia among whites are caused by antibodies against human platelet antigen 1a (HPA-1a). The aims of this systematic review and meta-analysis are to determine the association between maternal HLA-DRB3∗01:01 and: (1) HPA-1a-alloimmunization and (2) neonatal outcome in children born of HPA-1a-immunized women. A systematic liter

Fledging mass is color morph specific and affects local recruitment in a wild bird

Early-life conditions may have long-lasting effects on life history. In color polymorphic species, morph-specific sensitivity to environmental conditions may lead to differential fitness. In tawny owls (Strix aluco), pheomelanin-based color polymorphism is expected to be maintained because the brown morph has higher adult fitness in warmer environments, while selection favors the gray morph under

Long-term effects of hyperbaric oxygen therapy on visual acuity and retinopathy

Hyperbaric oxygen (HBO2) therapy is an adjunct treatment for diabetic foot ulcers. Since plausible mechanisms of action for this treatment include increased angiogenesis and high tissue oxygen concentrations, concerns about deterioration of retinopathy have been raised. The aim of this study was to evaluate the effects of HBO2 on visual acuity (VA) and retinopathy in patients with chronic diabetic

The rapid “teabag” method for high-end purification of membrane proteins

Overproduction and purification of membrane proteins are generally challenging and time-consuming procedures due to low expression levels, misfolding, and low stability once extracted from the membrane. Reducing processing steps and shortening the timespan for purification represent attractive approaches to overcome some of these challenges. We have therefore compared a fast “teabag” purification

Environmental factors in trade during the great transformation : Advancing the geographical coverage before 1950

In the study of trade-embedded environmental factors (land, water, energy, or material flows), three conflicting interpretations prevail concerning what happened before 1950. The 'great specialization' narrative argues that trade served to lighten pressure on the environment by redistributing environmental services from where they were abundant to where they were scarce. The 'great divergence' see

Coupled Agricultural Subsidies in the EU Undermine Climate Efforts

Subsidizing polluting industries generally leads to increased pollution locally. However, given the diversity of production technologies across countries and international trade, the global impact of unilateral policies is not a priori clear. We use the agricultural sector model CAPRI to simulate the impact of removing the voluntary coupled support for ruminants, presently permitted under the EU C
