objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...

BACKGROUND The objective was to evaluate the eye care services offered to older residents living in long-term care facilities (LTCFs). METHODS A questionnaire targeting residents aged ≥65 years was sent to all LTCFs in Quebec. Questions related to the institution's characteristics, demographic data related to residents, oculovisual health of residents and barriers to eye care, eye care servic...

This paper covers our recent work regarding family caregiver burden for elderly. The topics are as follows: cross-sectional studies on caregiver burden; changes in caregiver burden; appropriateness of the Long-Term Care insurance assessment scheme; attitude towards caregiving among caregivers; and the development of the short version of the Japanese version of the Zarit Caregiver Burden Interview.

Neonatal necrotizing enterocolitis (NEC) is the most important neonatal problem in nursery which is associated with high neonatal mortality and morbidity. NEC also leads to various long term complications, including short bowel syndrome, systemic infection, eye problems, nutritional deficiency and neurodevelopmental impairments. Lactoferrin (LF) is a component of breast milk and multiple action...

Monocrotaline (MCT) is commonly used to experimentally induce pulmonary hypertension (PH), which might lead to chronic heart failure. In this study, linear and non-linear heart rate (HR) dynamics were weekly assessed in MCT-treated and non-treated Wistar rats. The HR of 10 adult Wistar rats injected with MCT (MCT group) and of 10 similar rats injected with vehicle (non-MCT group), anesthetized ...

Heart rate variability (HRV) is the result of variation in time between two successive heart beats. HRV is the tool for investigation of healthy and diseased condition. It also reflects an influence of autonomic nervous system on function of heart. In this study, our aim is to distinguish normal sinus rhythm from atrial fibrillation and Supraventricular arrhythmia. Here the ECG signal is pre-pr...

the acceptability of hearing aids in people with presbyacusis has been improved but assessment of whether there is a need for more counseling to increase the number of regular hearing-aid users seems to be important. the aim of this study was to determine if the hearing aid was worn regularly and over a long period of time in people with presbyacusis. a questionnaire survey of patients with pre...

the effect of endogenous serotonin on long-term potentiation (ltp) in region cai was studied by blocking 5-ht2 receptors with ketanserin in rat hippocampal slices. such a block significantly en-hanced long-term potentiation of the cai population spike induced by high frequency stimulation of the schaffer collateral/ commissural pathway. this implies that serotonin acts on 5-ht2 receptors in cai...
