2. 1. Development and three-dimensional histology of vertebrate dermal fin spines

   Author : Anna Jerve; Per Erik Ahlberg; Martin Brazeau; Tatjana Haitina; Philippe Janvier; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fin spine; paleontology; early vertebrate; histology; development; Biology with specialization in Evolutionary Organismal Biology; Biologi med inriktning mot evolutionär organismbiologi;

   Abstract : Jawed vertebrates (gnathostomes) consist of two clades with living representatives, the chondricthyans (cartilaginous fish including sharks, rays, and chimaeras) and the osteichthyans (bony fish and tetrapods), and two fossil groups, the "placoderms" and "acanthodians". These extinct forms were thought to be monophyletic, but are now considered to be paraphyletic partly due to the discovery of early chondrichthyans and osteichthyans with characters that had been previously used to define them.

4. 2. Atrial fibrillation after cardiac surgery : an analysis of risk factors, mechanisms, and survival effects

   Author : Giovanni Mariscalco; Bengt Åberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; adult; cardiac surgery; coronary artery bypass grafting; valvular surgery; cardiopulmonary bypass; mortalilty; histology; catecholamines; embolism; Surgery; Kirurgi;

   Abstract : Background: Despite the recent improvements in surgical techniques and postoperative patient care, atrial fibrillation (AF) remains the most frequent complication after cardiac surgery. Although postoperative AF is often regarded as a benign clinical condition, this arrhythmia has significant adverse effects on patient recovery and postoperative survival. READ MORE

5. 3. Dopamine neurons in ventral mesencephalon : interactions with glia and locus coeruleus

   Author : Elisabet Berglöf; Ingrid Strömberg; Stephen B. Dunnett; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson’s disease; ventral mesencephalon; nerve fiber formation; glia; locus coeruleus; grafting; antioxidant-enriched diet; Histology; Histologi;

   Abstract : Parkinson’s disease is a progressive neurodegenerative disorder, characterized by a depletion of the dopaminergic neurons in the substantia nigra. The cause of the disease is yet unknown but age, oxidative stress, and neuroinflammation are some of the features involved in the degeneration. READ MORE

6. 4. The Entheses of the Medial Meniscns and Ligaments of the Knee Joint : Descriptive and Experimental Studies

   Author : Jizong Gao; Michael Benjamin; Linköpings universitet; []
   Keywords : knee joint; meniscus; ligaments; insertion; enthesis; quantitative morphology; fibrocartilage; cement line; collagens; proteoglycans; nerve fibres; tensile strength; failure mode; transection; refixation; repair; healing; osteoarthrosis; histology; immunohistochemistry; biomechanics; rabbit model; MEDICINE; MEDICIN;

   Abstract : Meniscal injuries are common in sports. Surgical removal of the meniscus to relieve symptoms is associated with a high risk for late knee joint osteoarthrosis and pain. Meniscal repair or replacement has therefore been advocated. READ MORE

7. 5. Cell-Specific Ca2+ Response in Pancreatic ß-cells

   Author : Natalia Gustavsson; Per Lindström; Peter Bergsten; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heterogeneity; individual ß-cells; islets of Langerhans; cytoplasmic calcium; repetitive glucose stimulation; lag-time; cell-specific; glyceraldehyde; ketoisocaproic acid; tolbutamide; mitochondrial metabolism; Histology; Histologi;

   Abstract : Pancreatic ß-cells are heterogeneous in their secretory responsiveness, glucose sensitivity and metabolic rate. A diminished and delayed first-phase insulin release is an early sign of failing ß-cells in diabetes. READ MORE
