2. 1. Physiology of Adventure Racing : with emphasis on circulatory response and cardiac fatigue

   Author : C. Mikael Mattsson; Björn Ekblom; Keith P George; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiovascular drift; cardiac fatigue; adventure race; cardiac biomarkers; cardoac function; exercise echocardiography; Physiology; Fysiologi; Cardiology; Kardiologi; Sports; Idrott; Medicin Teknik; Medicine Technology;

   Abstract : The overall aims of this thesis were to elucidate the circulatory responses to ultra-endurance exercise (Adventure Racing), and furthermore, to contribute to the clarification of the so called “exercise-induced cardiac fatigue” in relation to said exercise. An Adventure race (AR) varies in duration from six hours to over six days, in which the participants have to navigate through a number of check-points over a pre-set course, using a combination of three or more endurance/outdoor sports, e.

4. 2. Human muscle spindles : complex morphology and structural organisation

   Author : Jing-Xia Liu; William K. Ovalle; Umeå universitet; []
   Keywords : human; muscle spindle; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; anatomi; Human Anatomy;

   Abstract : Muscle spindles are skeletal muscle mechanoreceptors that mediate the stretch reflex and provide axial and limb position information to the central nervous system. They have been proposed to play a major role in the pathophysiology of muscle pain. READ MORE

5. 3. Structure and function of the cytoskeleton in cardiac and skeletal muscle

   Author : Johanna Balogh; Institutionen för experimentell medicinsk vetenskap; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ATP-receptor; Cardiovascular system; Kardiovaskulära systemet; cardiomyopathy; transgenic mice; skeletal muscle; heart; muscle contraction; cytoskeleton; desmin;

   Abstract : We have examined the functional and structural roles of the cytoskeletal protein desmin in cardiac and skeletal muscles using a genetically modified mouse (Des-/-) with the desmin gene ablated. Desmin forms filaments at the Z-disks in the striated muscle sarcomere, have connections to the sarcolemma and most likely align sarcomeres and whole cells. READ MORE

6. 4. Physical Activity and Cardiovascular Disease

   Author : Kasper Andersen; Johan Sundström; Claes Held; Frieder Braunschweig; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical activity; epidemiology; cohort study; heart failure; cardiovascular disease; arrhythmias; atrial fibrillation; bradyarrhythmias; sudden cardiac death; heart failure; stroke; ischemic heart disease; cardiovascular death; maximal exercise capacity; muscle strength; skeletal muscle morphology; Kardiologi; Cardiology; Epidemiology; Epidemiologi;

   Abstract : The aim was to investigate associations of fitness and types and levels of physical activity with subsequent risk of cardiovascular disease.Four large-scale longitudinal cohort studies were used. The exposures were different measures related to physical activity and the outcomes were obtained through linkage to the Swedish In-Patient Register. READ MORE

7. 5. Genetic studies of zebrafish muscles : clues to protection in muscle disease

   Author : Nils Dennhag; Fatima Pedrosa Domellöf; Jonas von Hofsten; Tatjana Haitina; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zebrafish; muscle; extraocular muscles; intermediate filaments; bioinformatics; genetics; CRISPR Cas9; oftalmiatrik; ophthalmology; cellforskning; cell research;

   Abstract : Muscular dystrophies (MDs) are caused by dysregulation of over 40 proteins but commonly share features of muscle weakness, myofiber death and regeneration, loss of ambulation and premature death. A MD involves a broken link anywhere in the connection from extracellular matrix through the sarcolemma to the sarcomere. READ MORE
