In the proofs that follow ϕ : R d → R always denotes a continuous positive definite function supported in the unit ball of R d with integral 1 and, for ϵ > 0, we write ϕ ϵ ( x ) = ϵ - d ϕ ( x / ϵ ), for the dilate of the function supported in the central ball of radius ϵ and again with integral 1.
We have focused on the less-studied replacement of astrocytes, the major support cell in the central nervous system, by generating astrocytes from embryonic human glial precursor cells using two different astrocyte differentiation inducing factors.
Gliomas are a particularly lethal solid tumor arising from support cells in the central nervous system, which can be divided into astrocytic tumors, oligodendrogliomas, and oligoastrocytomas.
Zygotically expressed Ttk69 plays a crucial role as a repressor of neuronal cell fate in glial cells and other support cells in the central and peripheral nervous system (Giesen et al., 1997; Badenhorst et al., 2002).
By Brigitte Stark-Merklein BANGUI, Central African Republic, 20 October 2009 – UNICEF Deputy Executive Director Hilde Johnson has called on the international community to support children in the Central African Republic (CAR) who are bearing the brunt of the country's declining fortunes.
Greenup garnered a majority of the vote in fifteen counties, just one fewer than Garrard, but Garrard enjoyed strong support in the populous central Kentucky counties and received 8,390 votes, compared with 6,746 for Greenup, 3,996 for Logan, and 2,166 for Todd.
They reckoned that such cells, known to produce neurons and other supporting cells in the central nervous system, might be coaxed into generating other sorts of cells when put in the right environment.
"Sometimes [Latter-day Saints] take positions in opposition to a federal proposal, and, in other cases, in support, but the central message is honoring and sustaining the law of the land," historian W. Paul Reeve told The Salt Lake Tribune.
In the past decade, a multiplicity of evidence has emerged in support of the central role of the human microbiome in the etio-pathogenesis of a wide variety of diseases.
Evidence in support of the central role of wear debris in periprosthetic loosening and osteolysis includes the observations that osteolysis is correlated with higher wear rates [ 2] and that vast numbers of wear particles are found associated with the periprosthetic interfacial membrane removed during revision surgery [ 3– 5].
