Japanese traditions keep ivory trade alive

'....officiously to keep alive'.

Modern medical technology has provided powerful tools with which to initiate and sustain life and understandable concern is being expressed about scientists and doctors 'playing God.' The view that 'the clinician's freedom to stop intensive treatment when the probable outcome is severe handicap is part of the package of neonatology" is far from unanimous. The hard facts are, however, that today...

Why Keep Them Alive

How to keep photoreceptors alive.

O ver the last 40 years, there has been increasing success in the surgical treatment of retinal detachment in that the retinal reattachment could be achieved in a high proportion of cases but visual recovery was frequently poor. An explanation for this poor visual outcome was derived from work on experimental retinal detachment in which it was shown that photoreceptor cell death occurred becaus...

Indication of Support for Keep-Alive

This specification defines a new Session Initiation Protocol (SIP) Via header field parameter, "keep", which allows adjacent SIP entities to explicitly negotiate usage of the Network Address Translation (NAT) keep-alive mechanisms defined in SIP Outbound, in cases where SIP Outbound is not supported, cannot be applied, or where usage of keep-alives is not implicitly negotiated as part of the SI...

Rods Feed Cones to Keep them Alive

Cone photoreceptors, responsible for high-resolution and color vision, progressively degenerate following the death of rod photoreceptors in the blinding disease retinitis pigmentosa. Aït-Ali et al. describe a molecular mechanism by which RdCVF, a factor normally released by rods, controls glucose entry into cones, enhancing their survival.
