    Abstract : Photosynthesis is probably the most important process for allowing life to develop into the diverse forms we see today. In this process, solar radiation is used to convert CO2 into biomass. From this process, we obtain oxygen to breathe, sources of food (plant biomass), and the potential for clean and sustainable energy. READ MORE

  4. 2. Structure studies of membrane associated proteins by transmission electron microscopy

    Author : Zuoneng Wang; Carsten Mim; Anna Sundborger Lunna; KTH; []
    Keywords : peripheral membrane protein PMP ; BAR protein; membrane curvature; actin dynamic; transmission electron microscopy; liposomes; Technology and Health; Teknik och hälsa;

    Abstract : Cell membranes need to change their shapes during many cellular processeslike protein trafficking, cytokinesis and membrane homeostasis. The lattershuttles lipids, synthesized in the endoplasmic reticulum, to all membranouscompartments. READ MORE

    Author : Yujie Liu; Gaston A. Crespo; Maria Cuartero; Alvaro Colina Santamaria; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ion-selective electrodes; electron-transfer and ion-transfer processes; spectroelectrochemistry; ultrathin membranes; thin-layer voltammetry; coulometry; Jonselektiva elektroder; elektronöverförings- och jonöverföringsprocesser; spektroelektrokemi; ultratunna membran; tunnskiktsvoltammetri; coulometri; Kemi; Chemistry;

    Abstract : Rapid and decentralized chemical sensing strategies are highly demanded in contemporary society to monitor ongoing processes relevant to the environment, food analysis, healthcare, sports performance, etc. In this context, ion-selective electrodes (ISEs) based on polymeric membranes have emerged as a promising analytical technique owing to their features of low cost, portability, versatility, and energy efficiency.

  6. 4. Mechanisms and time course of cell death in embryonic nigral tissue and intrastriatal transplants

    Author : Mia Emgård; Neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypothermia; resveratrol; free radicals; ultrastructure; electron microscopy; mesencephalic; transplantation; rat; Parkinson s disease; dopamine; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Abstract : Parkinson’s disease (PD) is the second most common neurodegenerative disorder and severely affects about one in a hundred persons over the age of fifty years. In PD, there is a reduced striatal concentration of the neurotransmittor dopamine, mainly caused by a degeneration of the dopaminergic neurons in the substantia nigra. READ MORE

  7. 5. On the antiporter-like subunits of respiratory chain Complex I - implications for the evolution and coupling mechanism of the NADH:quinone oxidoreductase enzyme complex

    Author : Cecilie Mathiesen; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Metabolism; Biokemi; metabolism; Biochemistry; mrp; electron transport; respiration; membrane protein;

    Abstract : Complex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. READ MORE
