1. 1. Nocturnal enuresis and rapid maxillary expansion : – long-term effect, prognostic variables, respiration during sleep and quality of life

   Författare :Ingrid Jönson Ring; Bazargani Farhan; Tryggve Nevéus; Agneta Markström; Maria Ransjö; Uppsala universitet; []
   Nyckelord :Rapid maxillary expansion; nocturnal enuresis; sleep disordered breathing; respiration; polygraphic sleep recording; quality of life.; Medicinsk vetenskap; Medical Science;

   Sammanfattning : Background:The orthodontic technique rapid maxillary expansion (RME) has been reported to have a potentially curative effect on nocturnal enuresis (NE). The mechanism behind this is unknown but could possibly be due to placebo and/or effects on respiration during sleep. LÄS MER

3. 2. Short- and long-term neuronal plasticity in hippocampal CA1 region of rat

   Författare :Fen-Sheng Huang; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glutamate; hippocampus; plasticity; synapse; LTP; LTD; AMPA; NMDA;

   Sammanfattning : The brain is highly plastic, displaying both short- and long-term changes, resulting from developmental processes as well as learning and memory. Moreover, short-term plasticity such as paired pulse facilitation and depression (PPF, PPD) have long been used to monitor the presynaptic versus postsynaptic changes occurring during more lasting processes such as long-term potentiation and depression (LTP, LTD).

4. 3. Ambulatory Monitoring and Analysis of Surface Electromyographic Signals in Ergonomic Field Studies - Methods and Applications

   Författare :Leif Sandsjö; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trapezius; ergonomic assessment tools; long-term recording; wearable systems; EMG; musculoskeletal disorders; work-related;

   Sammanfattning : Factors contributing to and the mechanisms behind the development of work-related musculoskeletal disorders (WMSDs) are still not fully known. Increased knowledge in this area is necessary in order to recommend appropriate actions to counteract the increasing costs to society and reduce the individual suffering related to these problems.

5. 4. Activity-dependent changes of synaptic transmission in a long-term perspective and processes involved

   Författare :Mikhail Dozmorov; Göteborgs universitet; []
   Nyckelord :synaptic plasticity; hippocampus; LTP; LTD; AMPA; NMDA; protein synthesis;

   Sammanfattning : Synaptic plasticity is an essential property of the central nervous system. It is thought torepresent a mechanism for memory aquisition, storage and recall. The most well studied forms ofsynaptic plasticity are homosynaptic NMDAR-dependent LTP and LTD in the hippocampus inducedby specific patterns of electrical stimulation. LÄS MER

7. 5. Treatment of obstructive sleep apnea with a mandibular advancement device

   Författare :Marie E. Marklund; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Activator appliances; Advancement mandibular; Cephalometry; Long-term effect; Polysomnography; Sleep apnea syndromes; Snoring; Supine position;

   Sammanfattning : Obstructive sleep apnea is associated with snoring, excessive daytime sleepiness, hypertension and an increased risk of early death.The aims of the present studies were to evaluate the short-term and longterm effects on sleep apnea and the tolerability of a one-piece, individually- designed mandibular advancement device.
