Popular science summary: Is RpS6 activation important for leukemia cell progression? Acute Myeloid Leukemia (AML) is the most common acute blood cancer in adults. It is characterized by a rapid increase of leukemic cells in the bone marrow, compromising the development of new blood cells. Despite improvement in treatments and advancements in supportive care, the overall 5-years survival of AML i
Background: Plasmodium falciparum malaria is an important cause of morbidity in northern Uganda. This study was undertaken to assess village-, household-, and individual-level risk factors of asymptomatic falciparum malaria in children in 12 villages in northern Uganda. Methods: Between 10/2011 and 02/2014, 1006 apparently healthy children under 16 years old were enrolled in 12 villages using a st
This study investigates the challenges and potential pathways for improved science communication, particularly in regards to research on the topic of smallholder food security and for science being generated by universities in sub-Saharan Africa. Questions asked in this study include those that aim to identify the academic substrate from which a university based in Africa must navigate. It also id
Background: B-vitamins are essential for one-carbon metabolism and have been linked to colorectal cancer. Although associations with folate have frequently been studied, studies on other plasma vitamins B2, B6, and B12 and colorectal cancer are scarce or inconclusive. Methods: We carried out a nested case-control study within the European Prospective Investigation into Cancer and Nutrition, includ
It has been generally accepted that residual cartilage and subchondral bone has to be removed in order to get bony fusion in arthrodeses. In 1998 we reported successful fusion of 11 rheumatoid ankles, all treated with percutaneous fixation only. In at least one of these ankle joints there was cartilage left. More than 25 rheumatoid patients with functional alignment in the ankle joint have subsequ
Popular Abstract in Swedish Det finns ett starkt samband mellan en förenings struktur och dess egenskaper. En detaljerad tredimensionell bild av en förenings struktur på molekylnivå är därför grundläggande information för att förstå dess reaktivitet, stabilitet och fysikaliska egenskaper. Röntgenkristallografi är ett utmärkt redskap för att ta reda på ett ämnes struktur i en kristall. En kristallsThis thesis focuses on i) the effect of packing on the molecular geometry ii) packing arrangements of neutral Pd(II) and Pt(II) complexes iii) the trans influence in Pt(II) complexes iv) the differences in bonding in corresponding Pd(II) and Pt(II) complexes and v) the geometry of Pd(II) complexes with potential catalytic properties.

Popular Abstract in Swedish Den svenska grundskolan har under de senaste åren genomgått och genomgår fortfarande en stark utveckling inom ramen för den allmänna decentraliseringen i samhället. Beslut och ansvar läggs allt längre ner i organisationen. De krav som ställdes på en skolledare tillbaka i tiden var i första hand att han skulle vara administratör och den som bevakade att skolans verk-samThe issues of the study are: How do the assistant principals face the work as school leaders? Which demands of competence do the new school leaders face? Which needs of competence development exist for new school leaders? In the school studied the organization of the management was changed from one principal and one director of studies to one principal and six assistant principals. All of these we
PURPOSE: To investigate whether separate physical tests of the lower extremities, that assess movement speed and postural control, were associated with cognitive impairment in older community-dwelling subjects. SUBJECTS AND METHODS: In this population-based, cross-sectional, cohort study, the following items were assessed: walking speed, walking 2 × 15 m, Timed Up and Go (TUG) at self-selected an
We determined whether single nucleotide polymorphisms (SNPs) previously associated with diabetogenic traits improve the discriminative power of a type 2 diabetes genetic risk score. Participants (n = 2,751) were genotyped for 73 SNPs previously associated with type 2 diabetes, fasting glucose/insulin concentrations, obesity or lipid levels, from which five genetic risk scores (one for each of the
Leachate treatment is one of the major environmental issues faced by landfill owners. One promising method for reduction of pollutant discharge is reverse osmosis (RO). RO technology was tested at a pilot plant at Hedeskoga Landfill in southern Sweden. This landfill receives municipal solid waste (MSW) and industrial, commercial and institutional (IC&I) waste, and produces about 3000 m3/ha of
Between 1977 and 1996, cytogenetic investigations were performed on 182 childhood (< or = 16 yr) acute lymphoblastic leukemias (ALL), constituting 94% (182 of 194) of all ALL patients diagnosed and treated at the Departments of Pediatrics, Lund and Malmo University Hospitals, Sweden, during these two decades. The cytogenetic analyses were successful in 152 cases (84%). The failure rate was higher
The simulation of current and projected wildfires is essential for predicting crucial aspects of vegetation patterns, biogeochemical cycling as well as pyrogenic emissions across the African continent. This study uses a data-driven approach to parameterize two burned area models applicable to dynamic vegetation models (DVMs) and Earth system models (ESMs). We restricted our analysis to variables f
Studies that have examined the association between alcohol consumption and gastric cancer (GC) risk have been inconsistent. We conducted an investigation of 29 genetic variants in alcohol metabolism loci (alcohol dehydrogenase, ADH1 gene cluster: ADH1A, ADH1B and ADH1C; ADH7 and aldehyde dehydrogenase, ALDH2), alcohol intake and GC risk. We analyzed data from a nested case-control study (364 cases
In order to simplify and/or improve determination of glomerular filtration rate (GFR) the clearances of iohexol, 51Cr-EDTA and endogenous creatinine were simultaneously determined with different techniques in 21 anesthetized landrace pigs. Their GFR had been reduced to about 1/3 or less of normal GFR. After an intravenous bolus of the GFR markers, their plasma concentration curves were followed fo
This thesis is based on three scientific papers dealing with different models for coordinated control of multi-stage inventory systems. The ability to control multi-echelon inventory systems, is paramount for reducing tied up capital and inventory costs in large distribution systems. It is also one key issue in achieving efficient supply chain management. We focus our attention on a general distr
BackgroundEarly detection of diabetes and hypertension is helpful to prevent and/or delay the onset of these diseases through proper interventions. Therefore, it is a prerequisite to know the prevalence of prediabetes and prehypertension and the factors associated with these conditions but people from developing countries including Bangladesh often remain undiagnosed and unaware of these condition
Forests are invaluable terrestrial ecosystems with considerable economic, ecological, and environmental benefits. Bark beetles have been recognized as one of the major causes of forest disturbance, and climate change can exacerbate their impact, leading to more tree mortality. Early detection of bark beetle attacks is vital to reduce forest loss and devastating consequences. This study examines th
Attention Restoration Theory point to nature as a particularly good candidate for restoring the ability to focus and inhibit distractions. However, little effort has been directed to elaborating on what makes nature's visual pattern unique for restoration purposes. One suggested explanation is the fractal properties of natural patterns (Hagerhall, 2005). Both perception studies (Hagerhall et al.,
Cement är ett av världens mest använda material och agerar som bindemedel i betong och murbruk. Portlandcement, som är den mest förekommande typen av cement, produceras årligen i en kvantitet av fyra miljarder ton. Cementproduktionen står för ca 7 % av de globala koldioxidutsläppen och det finns ett stort intresse i att hitta alternativa vägar och optimeringsmöjligheter, för att minimera klimatpåvCement is one of the world's most used materials and acts as a binder in concrete and mortar. Portland cement, which is the most common type of cement, is produced annually in a quantity of four billion metric tons. Cement production accounts for approximately 7 % of the global carbon dioxide emissions and there is a great interest in finding alternative routes and optimization possibilities,
Environmental problems are a discussed subject in the world. The reason for this is that natural disasters are becoming more and more visible. EU is working to reduce the Union's contribution to the greenhouse effect. The goal is to reduce greenhouse gases with 20% by 2020 and 20% of the energy used should come from renewable energy sources. The EU’s Energy Performance of Building Directive (E
