1. 6. Overcoming Limitations of Iontronic Delivery Devices

   Författare :Maria Seitanidou; Magnus Berggren; Daniel T Simon; Christopher Bettinger; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Organic electronic devices are considered as one of the best candidates to replace conventional inorganic electronic devices due to their electronic conductive functionality, low-cost production techniques, the ability to tune their optical and electronic properties using organic chemistry, and their mechanical flexibility. Moreover, these systems are ideal for bioelectronic applications due to their softness, biocompatibility, and most importantly, their electronic and ionic transport. LÄS MER

3. 7. Ion Transport in Cross-linked Nanocellulose Membranes

   Författare :Hongli Yang; Isak Engquist; Magnus Berggren; Klaus-Dieter Kreuer; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membranes; Nanocellulose; Cross-linking; Ion transport; Energy harvesting and storage devices;

   Sammanfattning : Ion-selective membranes, which allow ions with a certain charge and/or size to pass through while blocking other ions, have attracted much attention due to their diverse applications and outstanding roles in overcoming problems related to energy. In addition to the performance, the financial cost and renewability of materials are equally significant in the development of these membranes. LÄS MER

4. 8. Physiological and morphological aspects of the glomerular barrier in health and disease. Results based on experimental studies in the rat

   Författare :Clara Hjalmarsson; Göteborgs universitet; []
   Nyckelord :glomerular permeability; isolated perfused kidney; charge; endothelial surface layer; glycocalyx; electron microscopy; orosomucoid; nephrotic syndrome; proteinuria;

   Sammanfattning : Tremendous amounts of fluid are filtered every day through the kidneys. The anastomosing capillary loops surrounded by Bowman s capsule, forming the glomerulus, function in accordance with the interplay between the hydrostatic and the colloid osmotic pressure. The result of the action of these mechanisms is the production of primary urine. LÄS MER

5. 9. Properties of the endothelial cells and the glomerular barrier

   Författare :Jenny Sörensson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Capillary permeability; kidney glomerulus physiology; isolated perfused kidney; endothelium; orosomucoid; charge; horseradish peroxidase; inflammation; proteoglycan; cAMP.;

   Sammanfattning : The kidneys are vital organs that filter plasma to produce 180 liters of primary urine per day. Only 1% of this volume is excreted and the rest is reabsorbed. Naturally, such huge amounts of fluid must be well controlled to maintain the homeostasis, which is a prerequisite for life. LÄS MER

7. 10. Identification and characterization of kidney glomerulus-associated genes and proteins

   Författare :Ljubica Perisic; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The kidney glomerulus is a micro-organ comprised of a molecular filtration barrier that prevents the loss of blood proteins into the primary filtrate. This function is dependent on the coordination of its three constituent layers: the endothelium, the glomerular basement membrane and the podocytes. LÄS MER
