  2. 21. Population-based studies of higher-level gait disorders and hydrocephalus : focused on brain ventricular morphometry and patient outcomes following shunt surgery

    Author : Jenny Larsson; Jan Malm; Anders Eklund; Hanna Israelsson Larsen; Lars-Owe D. Koskinen; Uwe Kehler; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Higher-level gait disorder; Idiopathic Normal Pressure Hydrocephalus; Ventriculomegaly; Falls; Fear of Falling; Self-efficacy; Depression; Quality of life; Adverse events; Headache; Epilepsy; Abdominal pain;

    Abstract : Background: To study gait is of great importance for the health of the aging population. Higher-level gait disorders (HLGD) are characterized by a slow, symmetrical, unsteady gait. Its cause is most often unknown. HLGD in combination with ventriculomegaly (i. READ MORE

  4. 22. Morphometry of the Optic Nerve Head as a Diagnostic Tool for Glaucoma

    Author : Camilla Sandberg Melin; Per Söderberg; Boel Bengtsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; optic nerve head; ONH; nerve fibers; glaucoma; optical coherence tomography; OCT; Pigment epithelium central limit-inner limit of the retina minimal distance; PIMD; PIMD-2π; Segmental PIMD-2π; confocal scanning laser tomography; HRT; NRA; variation; variability; variance; loss rate; follow-up.;

    Abstract : Glaucoma is a chronic optic nerve head (ONH) disease. Gradual retinal ganglion cell and nerve fiber loss lead to morphological ONH change and visual field defects. Initial loss is often focal. Rate of progression and life expectancy guide treatment. READ MORE

  5. 23. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition

    Author : Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; brain plasticity; structural plasticity; magnetic resonance imaging; voxel-based morphometry; tractography; connectivity; motor cortex; posterior parietal cortex; cerebellum; vesicular glutamate transporter;

    Abstract : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. READ MORE

  6. 24. Neural correlates of individual differences in personality and intelligence : studies using an isochronous timing task and voxel based morphometry

    Author : Lea J Forsman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : It is easy to imagine that humans have always noticed the differences between themselves and others and perhaps even speculated about the origins of these differences. The study of individual differences as a formal field encompasses variations in intelligence and personality as well as other dimensions. READ MORE

  7. 25. The exocytotic and crinophagic pathways in ECL cells of the rat stomach

    Author : Chun-Mei Zhao; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; toxicology; ECL cells - Exocytosis - Crinophagia - Histamine - Gastrin - Morphometry - Stomach - Ultrastrucuture; pharmacognosy; pharmacy; Pharmacological sciences; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : The ECL cells in the stomach produce, store and secrete a variety of secretory products, such as histamine and chromogranin A-derived peptides (e.g. pancreastatin). The functional significance of the ECL cells can be expected to reflect the nature/bioactivity of the secreted products. READ MORE
