Induction of cerebral beta-amyloidosis: Intracerebral versus systemic A beta inoculation

Despite the importance of the aberrant polymerization of A beta in the early pathogenic cascade of Alzheimer's disease, little is known about the induction of A beta aggregation in vivo. Here we show that induction of cerebral beta-amyloidosis can be achie ...

Do spike insoles enhance postural stability and plantar-surface cutaneous sensitivity in the elderly?

Estelle Palluel

Balance problems are often related to a loss of plantar-sensitivity in elderly people. The purpose of this study was to explore the contribution of plantar cutaneous inputs induced by a spike support surface to the control of stance. Nineteen elderly (mean ...

How body position changes visual vertical perception after unilateral vestibular loss

Christophe Lopez

Visual vertical perception, posture and equilibrium are impaired in patients with a unilateral vestibular loss. The present study was designed to investigate whether body position (standing upright, sitting on a chair and lying supine) influences the visua ...

Ambulatory monitoring of motor functions in patients with Parkinson's disease using kinematic sensors

Arash Salarian

Parkinson's disease (PD) is the second most common neurodegenerative disease in the general population. Cardinal symptoms of Parkinson's disease are resting tremor, rigidity, akinesia and bradykinesia and in advanced stages, gait impairments, postural inst ...

Deletion of peroxisome proliferator-activated receptor-alpha induces an alteration of cardiac functions

Johan Auwerx, Kristina Schoonjans

The peroxisome proliferator-activated receptor-alpha (PPARalpha) plays a major role in the control of cardiac energy metabolism. The role of PPARalpha on cardiac functions was evaluated by using PPARalpha knockout (PPARalpha -/-) mice. Hemodynamic paramete ...

Dopaminergic fiber protection and regeneration by Wlds protein and GDNF in rodent models of Parkinson disease

Ali Etemad-Sajadi

Parkinson disease (PD) is a common neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the substantia nigra pars compacta. The resulting failure of the nigrostriatal pathway leads to profound dopamine deficiency, cau ...

Ambulatory system for the quantitative and qualitative analysis of gait and posture in chronic pain patients treated with spinal cord stimulation

Kamiar Aminian, Anisoara Ionescu, Bijan Najafi

The physical activity in normal daily life is determined to a large extent by the functional ability of a subject. As a result, the measurement of the physical activity that a subject performs spontaneously could be a useful and objective measurement of di ...

Temporal lobe epilepsy and postural orthostatic tachycardia syndrome (POTS)

Olaf Blanke

We describe a 20-year-old woman suffering from right temporal epilepsy, behavioral disorder, and a complaint of paroxysmal palpitations accompanied by anxiety. Detailed cardiac evaluation revealed that the palpitations were due to episodes of marked sinus ...

ESMAC-SIAMOC 2001 Joint Congress: Body Postures and Walking Period Estimation Using a Kinematic Sensor: Application for Long Term Monitoring of Physical Activity in Elderly Subjects

Kamiar Aminian, Philippe Robert, Anisoara Ionescu, Bijan Najafi

Introduction: A reliable measurement of the physical activity in everyday life should allow a better assessment of the utility and the relevance of a number of medical treatments. Continuous 24-h recordings of posture and motion can be generally useful in ...

Physical activity monitoring based on accelerometry: validation and comparison with video observation

Kamiar Aminian, Philippe Robert

The objective of this feasibility study is to evaluate the use of the 'Physilog' device, an ambulatory physical- activity recorder based on acceleration measurement, for the monitoring of daily physical activities. Accelerations measured at the level of th ...
