The compounds of mercury can be highly toxic and can interfere with a range of biological processes, although many aspects of the mechanism of toxicity are still obscure or unknown. One especially intriguing property of Hg(II) is its ability to bind DNA directly, making interstrand cross-links between thymine nucleobases in AT-rich sequences. We have used a combination of small molecule X-ray diff
The physical boundaries of office work have become increasingly flexible. Work is conducted at multiple locations outside the office, such as at clients’ premises, at home, in cafés, or when traveling. However, the boundary between indoor and outdoor environment seems to be strong and normative regarding how office work is performed. The aim of this study was to explore how office work may be cond
A new setup for burning velocity measurements of liquid fuels at elevated pressures using the Heat Flux method has been constructed. The burner design has been improved comparing to previous studies in this and other laboratories. Laminar burning velocities were determined experimentally for ethanol+air and methanol+air mixtures over a range of conditions including equivalence ratio (0.8 to 1.3),
A recurrent concern in nature conservation is the potential competition for forage plants between wild bees and managed honey bees. Specifically, that the highly sophisticated system of recruitment and large perennial colonies of honey bees quickly exhaust forage resources leading to the local extirpation of wild bees. However, different species of bees show different preferences for forage plants
The report analyses women in violent extremism based on contemporary data for Sweden. Statistics are presented across various demographic and criminal indicators for violent far-left, far-right and Islamic extremistm, compared to same-sex siblings, to men in the same violent extremist milieus and to women in other antagonistic milieus. There are both similarities and differences between groups. Wo
Extended producer responsibility (EPR) schemes have proliferated across Europe and other parts of the world in recent years and have contributed to increasing material and energy recovery from waste streams. Currently, EPR schemes do not provide sufficient incentives for moving towards the higher levels of the waste hierarchy, e.g. by reducing the amounts of waste through incentivising the design
Fjärrvärme och fjärrkyla är ändamålsenliga system för distribution av värme och kyla i tätbebyggda områden. Dessa system är viktiga vid planeringen av framtida energieffektiva system på grund av deras höga potential för att integrera förnybara energikällor. Systemen spelar också en viktig roll i samhällets energiförsörjningssäkerhet, vilket gör dem till ett tvärvetenskapligt forskningsområde. Den District heating and cooling are efficient systems for distributing heat and cold in urban areas. They are a key solution for planning future urban energy-efficient systems due to their high potential for integrating renewable energy sources. The systems also play an important role in community resilience, which makes them a multidisciplinary research topic. The continuous development of these sys
Introduction: Lithium has proven efficacy in bipolar affective disorder (BAD) but induces tremor as a side effect in a quarter of patients. Lithium tremor (LT) shares some clinical characteristics of essential tremor (ET) and Parkinson’s disease tremor (PT), which might cause difficulties in differential diagnosis. Furthermore, current knowledge of LT is lacking detailed electrophysiological chara
OBJECTIVE: To evaluate compliance to workflow and accuracy of tests in Sweden's first fast-track referral pathway for patients with nonspecific symptoms and suspected cancer (SCAN).DESIGN: Prospective cohort study with consecutive inclusion of patients referred to the diagnostic center (DC).SETTING: Patients with nonspecific symptoms were examined in primary care according to a protocol including
With the identification of novel antibiotics from nature being pivotal in the fight against human pathogenic bacteria, there is an urgent need for effective methodologies for expedited screening of crude extracts. Here we report the development and validation of a simple and dye-free antimicrobial assay in 96-well microplate format, for both determination of IC50 values and high-resolution inhibit
The losses of honey bee colonies and declines of other insect pollinators have been associated with negative effects of pesticides. Honey bees as well as other pollinators are nectar and pollen foragers and thus are exposed to an extensive range of phytochemicals. Understanding the synergistic, additive, and antagonistic effects of plant secondary metabolites and pesticides in honey bees may help
Honey bees are important pollinators and are subject to numerous stressors, such as changing floral resources, parasites, and agrochemical exposure. Pesticide exposure has been linked to the decline in the global honey bee population. We have limited knowledge of the metabolic pathways and synergistic effects of xenobiotics in bees. Quercetin is one of the most abundant phytochemicals in plants an
Worldwide, 463 million people are affected by diabetes of which the majority is diagnosed with Type 2 Diabetes (T2D). T2D can ultimately lead to retinopathy, nephropathy, nerve damage, and amputation of the lower extremities. α-Glucosidase, responsible for converting starch to monosaccharides, is a key therapeutic target for the management of T2D. However, due to substantial side effects of curren
Bradshaw et al. (2021) make a call to action in light of three major crises—biodiversity loss, the sixth mass extinction, and climate disruption. We have no contention with Bradshaw et al.’s diagnosis of the severity of the crises. Yet, their call for scientists to “tell it like it is,” their appeal to political “leaders,” and the great attention they afford to human population growth as a main dri
A series of regioisomeric isosorbide mono-epoxides, as well as diastereomerically pure mono-epoxy derivatives, have been prepared and studied. Anionic ring-opening polymerization of methoxy-capped monomers produced linear polyethers tethered with isosorbide units. These reasonably high molecular weight polymers exhibited glass transition temperatures at around 10-15 °C and thermal stability up to
In most cases, antiretroviral therapy (ART) results in undetectable plasma HIV viral load (VL). Still, up to 25% of ART recipients may have detectable low-level viremia (LLV) of different amplitude and persistence. This thesis explores the impact of LLV during ART on virologic and clinical outcomes. Paper I–III are retrospective analyses based on InfCare HIV, a national quality register for people
Mohsen Rezaee, a high-ranking official of the Islamic Republic in Iran, has admitted that top-secret Iranian nuclear documents were stolen in a raid of a Tehran warehouse by Israeli operatives in 2018—a raid the regime had denied ever occurred. Rezaee is calling for a purge of the Iranian intelligence and counterintelligence community, which could result in Iranian intelligence operatives fleeing
