Comparison of the Effects of a Brand-name Drug and Its Generic Drug on the Quality of Life of Alzheimer's Disease Patients.

Objective: The pharmacological effects of generic (GE) donepezil are the same as Aricept, its brand-name counterpart. However, little is known as to whether these two drugs provide the same quality of life (QOL). The study subjects were patients with Alzheimer's disease who were taking donepezil hydrochloride tablets, and were selected by visiting either the local pharmacies or the patients' homes.

Methylxanthine-evoked perturbation of spontaneous and evoked activities in isolated newborn rat hippocampal networks.

Treatment of apnea of prematurity with methylxanthines like caffeine, aminophylline or theophylline can evoke hippocampal seizures. However, it is unknown at which interstitial brain concentrations methylxanthines promote such neonatal seizures or interfere with physiological 'early network oscillations' (ENOs) that are considered as pivotal for maturation of hippocampal neural networks. We studied theophylline and caffeine effects on ENOs in CA3 neurons (CA3-ENOs) and CA3 electrical stimulation-evoked monosynaptic CA1 field potentials (CA1-FPs) in sliced and intact hippocampi, respectively, from 8 to 10-days-old rats.

Methylxanthines do not affect rhythmogenic preBötC inspiratory network activity but impair bursting of preBötC-driven motoneurons.

Clinical stimulation of preterm infant breathing with methylxanthines like caffeine and theophylline can evoke seizures. It is unknown whether underlying neuronal hyperexcitability involves the rhythmogenic inspiratory active pre-Bötzinger complex (preBötC) in the brainstem or preBötC-driven motor networks. Inspiratory-related preBötC interneuronal plus spinal (cervical/phrenic) or cranial hypoglossal (XII) motoneuronal bursting was studied in newborn rat en bloc brainstem-spinal cords and brainstem slices, respectively.

Protective effect of thalidomide against N-methyl-D-aspartate-induced retinal neurotoxicity.

Thalidomide, an inhibitor of tumor necrosis factor-α (TNF-α) production, has been indicated to be useful for many inflammatory and oncogenic diseases. In the present study, we examined whether thalidomide (50 mg/kg/day, p.o.
