Assessment of time-related deficits in older adults: a scoping review protocol.

Introduction: People with cognitive impairments often have difficulties in managing their time for daily activities. In older adults with cognitive impairments such as dementia and stroke, these may present as disorientation, poor time awareness, time perception, daily time management and so on. Time-related deficits and associated behaviours impede independent living and add considerably to caregiver strain.

The application of an information support robot to reduce agitation in an older adult with Alzheimer's disease living alone in a community dwelling: a case study.

Objective/background: Agitation is a common behaviour of Alzheimer's Disease (AD). Although healing robots have previously been used for alleviating agitation for people with dementia in hospitals and other healthcare facilities, its effects remain unclear whether an information-support robot capable of disseminating information with user needs may have similar effects when it is applied in community dwellings. This study was to investigate the effects of information-support robots for reducing agitation in older people with AD residing alone in community-dwellings.

Effect of the Information Support Robot on the Daily Activity of Older People Living Alone in Actual Living Environment.

Information support robots (ISRs) have the potential to assist older people living alone to have an independent life. However, the effects of ISRs on the daily activity, especially the sleep patterns, of older people have not been clarified; moreover, it is unclear whether the effects of ISRs depend on the levels of cognitive function. To investigate these effects, we introduced an ISR into the actual living environment and then quantified induced changes according to the levels of cognitive function.

Neuregulin-1 type III knockout mice exhibit delayed migration of Schwann cell precursors.

In an embryonic developmental stage of the peripheral nervous system (PNS), Schwann cell precursors migrate along neuronal axons to their final destinations. After birth, they eventually wrap around individual axons to form myelin sheaths, which insulate axons to increase the nerve conduction velocity. Some growth factors and adhesion molecules are known to control these developmental stages from in the fish to in the mammal.

Involvement of the Tyro3 receptor and its intracellular partner Fyn signaling in Schwann cell myelination.

During early development of the peripheral nervous system, Schwann cell precursors proliferate, migrate, and differentiate into premyelinating Schwann cells. After birth, Schwann cells envelop neuronal axons with myelin sheaths. Although some molecular mechanisms underlying myelination by Schwann cells have been identified, the whole picture remains unclear.

Effects of deception for intensity on surface electromyogram (SEMG) activity and blood lactate concentration during intermittent cycling followed by exhaustive cycling.

The purpose of the present study was to determine the effects of deception for exercise intensity on surface electromyogram (SEMG) activity and blood lactate concentration during intermittent cycling exercise (ICE) tests. Sixteen healthy male were randomly assigned to two groups who completed two ICE [three 4-min cycling at 80% peak power output (PPO) with 3-min passive recovery periods followed by exhaustive cycling] tests (ICE-1 and ICE-2). The experimental group (ICED) was deceived of the actual cycling intensity, while the control group (ICEC) was informed of the actual protocol in ICE-2.
