7,5 högskolepoäng Kursinnehåll Vi börjar kursen med att kartlägga kopplingen mellan modern biologisk undersökande vetenskap och metoder, hypotestestning samt etik inom forskning. Sedan behandlar vi grundläggande statistik- och sannolikhetsteori, datahantering, statistiska analysmetoder för biologiska experiment, experimentell design samt utvärdering av experiment. Kursen ges på plats vårterminer p

Aerosol science is of utmost importance for both climate and public health research, and in recent years X-ray techniques have proven effective tools for aerosol-particle characterization. To date, such methods have often involved the study of particles collected onto a substrate, but a high photon flux may cause radiation damage to such deposited particles and volatile components can potentially
Many forms of inflammatory conditions are associated with alterations in physiology, metabolism and concentrations of trace elements such as copper, magnesium, zinc and calcium and of amino acid patterns and C-Reactive protein levels in plasma (1). Decreased levels of zinc and a reciprocal increase of copper in plasma has been seen in many human diseases (2). Nothing concrete is documented concern
Bile acids (BAs) are known to be involved in cholesterol metabolism but interactions between the diet, BA profiles, gut microbiota and lipid metabolism have not been extensively explored. In the present study, primary and secondary BAs including their glycine and taurine-conjugated forms were quantified in serum of Apoe−/− mice by protein precipitation followed by reversed phase ultra-high-perform
rposes: Dietary supplementation with N-3 Polyunsaturated Fatty Acids (n-3 PUFAs) could have beneficial effects on cardiovascular system in patients with type 1 diabetes mellitus (DM1). Methods: In a double-blind placebo controlled crossover study, 33 children with DM1 duration of more than one year were randomly and equally assigned to either n-3 PUFAs (2 gm/day, Nycoplus® Omega-3, 1000 mg) or plaPurposes: Dietary supplementation with N-3 Polyunsaturated Fatty Acids (n-3 PUFAs) could have beneficial effects on cardiovascular system in patients with type 1 diabetes mellitus (DM1).

In a laboratory study we investigated 1) the potential production of nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2) and 2) the effect of nitrate (NO3−) and anaerobic N2O development on CH4 production in sediment from a recently recreated free surface water wetland (FSWW) and in soil from an adjacent meadow. We designed an experiment where production of greenhouse gases was registered
DNA carries the genetic code of life, with different conformations associated with different biological functions. Predicting the conformation of DNA from its primary sequence, although desirable, is a challenging problem owing to the polymorphic nature of DNA. We have deployed a host of machine learning algorithms, including the popular state-of-the-art LightGBM (a gradient boosting model), for b
Depicting developmental processes as movements in free energy genetic landscapes is an illustrative tool. However, exploring such landscapes to obtain quantitative or even qualitative predictions is hampered by the lack of free energy functions corresponding to the biochemical Michaelis– Menten or Hill rate equations for the dynamics. Being armed with energy landscapes defined by a network and its
Background: Analysis of sialic acid (SA) metabolites in cerebrospinal fluid (CSF) is important for clinical diagnosis. In the present study, a high-performance liquid chromatography-tandem mass spectrometry (HPLC/MS/MS) method for free sialic acid (FSA) and total sialic acid (TSA) in human CSF was validated. Methods: The method utilized a simple sample-preparation procedure of protein precipitatio
A novel macro intermediate based on poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) was synthesized for use in the copolymerization with dimethyl amino ethyl methacrylate (DMAEMA). Methyl amino ethanol was reacted with PHBHHx to prepare a dihydroxy terminated polyester. The hydroxyl ends of the obtained PHBHHx derivatives were capped with 4,4’-azobis cyanopentanoic acid to obtain the PHBHHx
Purpose: Artifacts impacting the imaged tumor volume can be seen in conventional three-dimensional CT (3DCT) scans for planning of lung cancer radiotherapy but can be reduced with the use of respiration-correlated imaging, i.e., 4DCT or breathhold CT (BHCT) scans. The aim of this study was to compare delineated gross tumor volume (GTV) sizes in 3DCT, 4DCT, and BHCT scans of patients with lung tumo
The free light chain (FLC) ratio is a critical part of risk stratification for monoclonal gammopathy of undetermined significance (MGUS). Recently, revised FLC reference intervals developed using the iStopMM cohort, accounting for age and renal function, have reduced the rate of abnormal findings. Here, we examine the implications of the revision in an independent Danish MGUS cohort. Of 6993 MGUS
