  2. 1. Cerebral arterial pulsatility imaging using 4D flow MRI : methodological development and applications in brain aging

    Author : Tomas Vikner; Anders Wåhlin; Anders Eklund; Jan Malm; Lars Nyberg; Susanne Schnell; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D flow MRI; medical image analysis; cerebral hemodynamics; arterial pulsatility; DCE MRI; blood-brain barrier; white matter lesions; perivascular spaces; cerebral small vessel disease; hippocampus; cognition; aging; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Abstract : 4D flow magnetic resonance imaging (MRI) is increasingly recognizedas a versatile tool to assess arterial and venous hemodynamics. Cerebral arterial pulsatility is typically assessed by analyzing flow waveforms over the cardiac cycle, where flow amplitude is a function of cardiac output, central arterial stiffness, and cerebrovascular resistance and compliance.

  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. Modelling and quantifying brain connectivity and dynamics with applications in aging and ADHD

    Author : Neda Kaboodvand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Human brain is a complex organ and made up of integrative networks encompassing a large number of regions. These regions communicate with each other to share information involved in complex cognitive processes. Functional connectivity (FC) represents the level of synchronization between different brain regions/networks. READ MORE

  6. 4. The matter of white matter in Alzheimer's disease. -On white matter disease from neuropathology and neuroimaging to clinical presentation

    Abstract : Alzheimer's disease (AD) is the most prevalent type of dementing disorder. The cortical pathology of AD has been recognized for almost a century. In later years, an associated pathological feature of AD has been identified which affects the white matter. READ MORE

  7. 5. Distal radius fractures AO type C : A clinical and radiographic investigation

    Author : Eva Lundqvist; Per Wretenberg; Marcus Sagerfors; Per Fischer; Magnus Tägil; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Distal radius fracture; patient-reported outcome measures; functional outcome; radiographic outcome; plating; volar locking plate; combined plating; surgical treatment; post-traumatic arthritis; wrist;

    Abstract : The function of the hand is of substantial importance, and injuries have an impact on daily life. Distal radius fracture (DRF) is the most common fracture among adults. The annual incidence is 26 per 10,000 inhabitants, and the incidence is increasing because of an aging population. READ MORE
