    Abstract : A balanced tear film is essential for a healthy ocular surface. Insufficient tear production may result in dry eye, a common disorder in the elderly population. Dry eye causes significant discomfort in the patients and may lead to visual impairment and ocular infections. READ MORE

  4. 2. Water-Metal Surfaces : Insights from core-level spectroscopy and density functional theory

    Author : Theanne Schiros; Anders Nilsson; John Hemminger; Stockholms universitet; []
    Keywords : water; hydroxyl; metal; surfaces; x-ray spectroscopy; density functional theory; bonding; fuel cell; kemisk fysik; Chemical Physics;

    Abstract : Computational methods are combined with synchrotron-based techniques to analyze the structure and bonding of water and water plus hydroxyl at metal surfaces under UHV and at near-ambient conditions. Water-metal interaction plays a crucial role in a multitude of cosmic, atmospheric and biological phenomena as well as heterogeneous catalysis, electrochemistry and corrosion. READ MORE

  5. 3. Hyaluronan and Renal Fluid Handling : Studies during Normal and Pathological Conditions of Renal Function

    Author : Viktoria Göransson; Mats Rundgren; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; CD44; gerbils; hyaluronan; ischemia-reperfusion; kidney; osmolality; oxygen tension; rat; renomedullary interstitial cells; water; Cellbiologi; Cell biology; Cellbiologi; Physiology; fysiologi;

    Abstract : The kidney is the major organ responsible for the regulation of the composition and volume of the body fluids, which is essential for homeostasis. The glycosaminoglycan hyaluronan (HA), with extreme water-binding capacity, is present in the interstitium of the kidney with a heterogenous distribution. READ MORE

  6. 4. Sperm Membrane Channels, Receptors and Kinematics : Using boar spermatozoa for drug toxicity screening

    Abstract : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. READ MORE

  7. 5. Regulation of Renal Hyaluronan in Water Handling : Studies in vivo and in vitro

    Author : Sara Stridh; Peter Hansell; Mats Rundgren; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; water balance; fluid handling; diabetes; nephropathy; ACE fetopathy; reabsorption; hyaluronic acid; glycosaminoglycan; GAG; extracellular matrix; mTOR; rapamycin; streptozotocin;

    Abstract : Hyaluronan (HA) is a negatively charged extracellular matrix (ECM) component with water-attracting properties. It is the dominating ECM component in the renal medullary interstitium, where the amount changes in relation to hydration status: it increases during hydration and decreases during dehydration.
