   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; mass spectrometry imaging MSI ; nanospray desorption electrospray ionization nano-DESI ; single-cell analysis; neurotransmitter imaging; diabetic nephropathy; pneumatic nebulization; lipidomics; metabolomics; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry;

   Sammanfattning : Ambient mass spectrometry (MS) has proved to be an important addition to the bioanalytical toolbox. These methods perform analyte sampling and ionization under atmospheric pressure, and require very little sample preparation other than the sampling process in front of the machine. LÄS MER

7. 25. Effects of Ubiquinone-10 on the Stability and Mechanical Properties of Lipid Membranes

   Författare :Emma K. Eriksson; Katarina Edwards; Victor Agmo Hernández; Emma Sparr; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ubiquinone-10; lipid bilayers; membrane stabilizer; liposome permeability; osmotic shock; cuvettes; solanesol; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

   Sammanfattning : Ubiquinones are a group of fat-soluble molecules present in many biological membranes. The most abundant version in humans, ubiquinone-10 (Q10), plays an important role in the mitochondrial respiration chain and also functions as a powerful antioxidant. Accumulating evidence suggests that Q10 also could have other functions in the membrane. LÄS MER
