Progressive augmentation (PA) and ventilatory long-term facilitation (vLTF) of respiratory motor output are forms of respiratory plasticity that are initiated during exposure to intermittent hypoxia. The present study was designed to determine whether PA and vLTF are enhanced in obstructive sleep apnoea (OSA) participants compared to matched healthy(More)
This study examined whether time of day and repeated exposure to intermittent hypoxia have an impact on the hypoxic ventilatory response (HVR) and ventilatory long-term facilitation (vLTF). Thirteen participants with sleep apnea were exposed to twelve 4-min episodes of isocapnic hypoxia followed by a 30-min recovery period each day for 10 days. On days 1(More)
We compared the intact alpha7 nicotinic acetylcholine receptor (alpha7nAChR) protein levels in the peripheral blood leukocytes in 15 Alzheimer's disease (AD) patients and 13 normal elderly control subjects. Demographic data and Mini-Mental State Examination (MMSE) scores were obtained. Western blot analysis for alpha7nAChR protein levels in peripheral blood(More)
We examined whether exposure to intermittent hypoxia (IH) during wakefulness impacted on the apnea/hypopnea index (AHI) during sleep in individuals with sleep apnea. Participants were exposed to twelve 4-min episodes of hypoxia in the presence of sustained mild hypercapnia each day for 10 days. A control group was exposed to sustained mild hypercapnia for a(More)
BACKGROUND Epilepsy is a chronic condition requiring compliance to long treatment regimes. Knowledge on epilepsy can affect compliance to treatment. Pediatric epileptic patients need caregivers for their care; however, prior research showed that caregivers had inadequate knowledge in epilepsy. In view of this, outpatient pharmacist epilepsy service was set(More)
Obstructive sleep apnea hypopnea syndrome (OSAHS) is largely under-diagnosed and unrecognized by primary care practitioners. Insidious changes within the respiratory and cardiovascular systems occur over time in untreated OSAHS. Respiratory manifestations of OSAHS include changes in the hypoxic ventilatory response, which can lead to long-term facilitation(More)
