2. 1. On magnesium-modified titanium coatings and magnesium alloys for oral orthopaedic applications : in vitro investigation

   Author : Francesca Cecchinato; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biocompatible material; Bone substitutes; Biomaterial; Dentala implantat;

   Abstract : In dentistry and orthopaedic surgery, research to find and developimproved biomaterials is progressing rapidly.Of specific interest is to accelerate bone formation around theimplant surface, which could improve the reliability of the implanteven in patients with compromised situations.

4. 2. Hair cell regeneration in vestibular epithelia : a study in an in vitro model

   Author : Mimmi Werner; Diana Berggren; Andrew Forge; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vestibular hair cell; regeneration; transdifferentiation; proliferation; utricle; rat; oto-rhino-laryngologi; Oto-Rhino-Laryngology;

   Abstract : BackgroundHair cells (HCs) are the sensory receptors in both the auditory and the vestibular organs of the inner ear. Supporting cells (SCs) are non-sensory cells embracing the HCs. Injuries of the HCs by aging, acoustic trauma or ototoxic drugs (mainly aminoglycosides, e.g. READ MORE

5. 3. Assessment of human swallowing using in-vivo and in-vitro approaches

   Author : Muhammad Waqas; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-vitro manometery; In-vitro simulations; In-vivo analysis; microstructure analysis; extensional rheology; dysphagia; Ultrasound viscometry; Bolus Rheology;

   Abstract : Texture modification is the most vital strategy to manage dysphagia: a condition in which food and beverages are difficult to swallow. Typically thickeners in the form of starch or gums are added to the food to increase the viscosity and thereby reduce the speed of bolus flow. READ MORE

6. 4. Mechanisms of muscarinic feedback regulation of acetylcholine release in rat hippocampus : an in vitro study

   Author : Öie Nordström; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The present study on dilute suspensions of synaptosomes from rat hippocampus yields evidence that feedback regulation of acetylcholine release in this preparation is exerted by a muscarinic autoreceptor localized on the cholinergic nerve ending itself.A possible model for the sequence of events which may take place at the cholinergic nerve ending is presented.

7. 5. In silico tools in risk assessment : of industrial chemicals in general and non-dioxin-like PCBs in particular

   Author : Mia Stenberg; Patrik Andersson; Miriam Jacobs; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; industrial chemicals; in silico tools; molecular descriptors; non-dioxin-like PCBs; partial least-squares PLS ; principal component analysis PCA ; quantitative structure-activity relationship QSAR ; REACH; risk assessment RA ; statistical molecular design; structure-activity relationship SAR ;

   Abstract : Industrial chemicals in European Union produced or imported in volumes above 1 tonne annually, necessitate a registration within REACH. A common problem, concerning these chemicals, is deficient information and lack of data for assessing the hazards posed to human health and the environment. READ MORE
