The continuously growing number of products containing nanoparticles makes their presence in the environment seem inevitable and given the well-known toxicity of dissolved metals, concerns regarding the toxicity of metal-based nanoparticles have been raised. Whether metal-based nanoparticles present similar or different toxicological effects compared to metal salts is a progressing field. In the p

Elförsörjningen som till huvuddel kommer från fossila bränslen uppfyller vanligen inte efterfrågan i Irak. Samtidigt som det finns goda förutsättningar och stor potential för att installera och utnyttja solel som en lösning för den bristande elförsörjningen men med omtanke som värnar om miljön. Idag har cirka 20 procent av den irakiska befolkningen ingen tillgång till el, de återstående 80 procentThe main supply of electricity from fossil fuels does not usually meet demand in Iraq. At the same time, there are good conditions and great potential for installing and utilizing environmental friendly electricity from solar energy as a solution to the lack of power supply. Today, about 20 percent of the Iraqi population has no access to electricity, the remaining 80 percent have no continuous el

An increase in large-scale agricultural investment in land has been going on since the global food crisis in 2008. Import-dependent countries have acquired large plots of land to secure food supplies. The investments had disastrous impacts on the local communities living on the land before the investment took place. Many have been expropriated and evicted from their lands, affecting their human ri

The world today stands at a cross roads when it comes to energy and electrical grids. A large part of the worlds population still lacks access to reliable working electricity 24 hours a day. Much of this is in remote and poor parts of the world. For much of the 20th century large centralized AC grids have been the norm to provide people with electricity. But for remote parts of the world including

Abstract: The importance of dietary fatty acids (FAs), in particular omega-3 and omega-6 polyunsaturated (PUFAs), for immune system functions has been recognised and well-studied in mammals over the last decades. Recent studies suggest that similar positive/negative (e.g. strengthened/weakened immune com-petence) effects can be present in avian species. In this study, I explored these effects of ω

Framväxten av separatistiska organisationer för rasifierade i Sverige har periodvis erhållit stor uppmärksamhet. Förespråkarna ser det som ett sätt för strukturellt underordnade att stärka varandra, medan belackarna ser det som begränsande och destruktivt. Förståelsen för hur diskursiva praktiker struktureras inom separatistiska rörelser är emellertid begränsad. I denna studie har en diskursanalys

Små flygande mikroalger – vilka är ni? Mikroalger är små encelliga fotosyntetiska mikroorganismer (1–500 μm i diameter), knappt synliga för ögat. De finns precis överallt omkring oss, i luften vi andas, i vattnet vi dricker och på våra husväggar. Det är inte mycket vi vet om dessa små mikroorganismer. Några av dem är luftburna, vilket innebär att de kan sprida sig långa sträckor med vindpustar fr

Brain Inflammation in Alzheimer’s disease Nowadays, Alzheimer’s disease (AD) is the main cause of dementia worldwide but still is not well understood how is the disease developed. However, there are few known factors that are important in the progression of the disease. In the last decade, the role of the inflammatory cells has been clearly link to the pathology. Hence, the aim of our project is

Aims/hypothesis The aims of this project was to investigate the effect of glucolipotoxic treatment on DNA methylation and gene expression patterns in pancreatic islets and functionally test if and how these changes alter insulin secretion. Methods Genome-wide mRNA expression and DNA methylation patterns were analyzed in human pancreatic islets after control or glucolipotoxic treatment. Alterations

Hur kan cellers försvarsmekanismer hjälpa oss förstå Parkinsons sjukdom? Parkinsons sjukdom är den andra mest vanliga neurodegenerativa sjukdomen i världen, och under sjukdomens gång dör allt fler hjärnceller vilket leder till svårigheter för hjärnan. När fler och fler celler försvinner, får hjärnan problem att kontrollera de signaler som den skickar ut till kroppen, vilket leder till symptom somParkinson’s disease (PD) is a movement disorder of the brain which is hallmarked by the presence of large protein-rich cytoplasmic aggregates, called Lewy bodies (LBs), in the neurons. The protein α-synuclein (α-syn) is abundant in these aggregates, and can itself form aggregates. Several mutations linked to α-syn are also linked to an increased risk of contracting PD. In healthy neurons, the chap

The question of whether the choice of performance measure (PM) matters when evaluating Hedge funds has for a long time been subject to debate . This study explores the same question with a sample of individual monthly data from 669 Hedge Funds over a 10 year period. The standard rank correlation tests usually applied when studying the topic yield weaker correlations between the PM:s in our study t

This thesis sets out to evaluate a risk-managed momentum strategy in the European stock market. The recent performance of momentum in Europe is first evaluated. A momentum premium still exists in Europe but the strategy suffered large losses in 2009. A risk-managed momentum portfolio is created by dynamically scaling the exposure to momentum based on a monthly volatility forecast. The risk-managed

p33 as a potential novel therapeutic target in inflammatory diseases Inflammation is a condition usually triggered by infection of invading pathogens such as bacteria or viruses in the body. This invasion is quickly recognized by specific receptors localized on the membrane of cells, ready to sense these so called “danger” signals or foreign material. These receptors are part of the innate immuni

This study utilizes Interpretative Phenomenological Analysis (IPA) to gain an in-depth understanding of transgender individuals’ transition experiences and thoughts regarding the diagnostic classification of Gender Dysphoria issued by the Diagnostic and Statistical Manual of Mental Disorders (DSM) and Transsexualism issued by the International Classification of Diseases (ICD). The study focused up

Cooking with culinary spices shows health benefits Every time we eat a meal, our body will turn into a post-meal state and face a lot of challenges induced by the food intake. These challenges include blood glucose spikes, triggered inflammation and increased total cholesterol concentrations. If these challenges happen too many times a day and reach an abnormal level, then there is a risk of deve

How are penicillin-binding proteins sorted in cells? A bacterial cell wall can be regarded as a brick building, in which the bricks and the cement hold the building together, provide structure for the building, protect its contents, and allow only certain substances to enter. Many antibiotics target proteins that function in cell wall morphogenesis (the process of building the brick wall in this

Investigating the role of mitochondrial damage in a Tuberculosis infection Tuberculosis (TB) is a significant health risk that was responsible for 10.4 million infections and 1.8 million deaths in the year 2015 alone. The causative agent for TB is Mycobacterium tuberculosis (Mtb), which is an intra-cellular bacterium that primarily replicates within the white blood cell called the macrophage. To

Vetenskapliga artiklar föreslår att xylan är delvis bundet till proteinerna i dulse. Detta kan leda till minskad tillgänglighet av proteinerna och leda till svårigheter att smälta dessa i tarmen. Denna rapport har för avsikt att hitta och optimera metoder för extraktion av proteiner och metoder för att separera de proteiner och polysackarider som förekommer i dulse. Metoderna som används är hydrolSeaweed has a great potential within human food and animal feed industry. Palmaria palmata (P. palmata) or more commonly dulse, is a type of red seaweed which has a high protein content (8-35%), rich in minerals such as iodine and iron and contain high levels of dietary fibers. The main polysaccharide in dulse is xylan. It has been suggested that the xylans are linked to the proteins in the seawee

In scanning probe microscopy the properties of the tip is crucial in determining which information that can be obtained from the resulting images and spectroscopy. Ordinarily metal tips are used for scanning, however by using semiconducting nanowires as tips one would have very well defined probes with more advanced possibilities for spectroscopic measurements. However, currently creating such hig
