Local Neuroretinal Function during Acute Hypoxia in Healthy Older People

Local neuroretinal function during acute hypoxia in healthy older people.

PURPOSE To measure the effect of acute, mild, systemic hypoxia on neuroretinal function in two different age groups. METHODS The slow-flash paradigm of the multifocal electroretinogram (mfERG) was measured in two different oxygenation levels. Twelve participants of two age groups (28 +/- 4 and 55 +/- 5 years) breathed room air (normoxia) or 12% oxygen (hypoxia). RESULTS During normoxia (SaO...

Physical Function in Older People

Sleep Quality in Healthy Older People

The hippocampus and thalamus assume a significant role in the overnight consolidation of memories, a process that is negatively impacted by sleep disruption. Emerging evidence suggests that disturbances of sleep in older people may co-occur with underlying neurobiological changes. This study sought to assess glial and neuronal integrity in these regions in relation to subjective sleep disturban...

The Effects of Modified Ankle Foot Orthosis on balance in Healthy Older People

Introduction: Balance impairment and related injuries are common in elderly and patients with neurologic disorders. Ankle foot orthosies can influence on balance via improvement of movement disorders. Therefore the aim of this study was to investigate the effects of modified ankle-foot orthosis on balance performance in healthy elderly.   Materials & Methods: The research was conducted on ten ...

Cutaneous vascular function during acute hyperglycemia in healthy young adults.

Although it is well established that severe chronic hyperglycemia is associated with microvascular disease, it is not known whether transient hyperglycemia similar to that observed with impaired glucose tolerance or early Type 2 diabetes contributes to this pathology by altering microvascular function. To test the hypothesis that acute hyperglycemia decreases microvascular vasodilator responsiv...
