PCR-based detection of non-indigenous microorganisms in ‘pristine’ environments
(Elsevier, 2003)
PCR-based technologies are widely employed for the detection of specific microorganisms, and may be applied to the identification of non-indigenous microorganisms in ‘pristine’ environments. For ‘pristine’ environments ...
Crystal structure of saposin B reveals a dimeric shell for lipid binding
(National Academy of Sciences, 2003)
Saposin B is a small, nonenzymatic glycosphingolipid activator
protein required for the breakdown of cerebroside sulfates (sulfatides) within the lysosome. The protein can extract target lipids
from membranes, forming ...
Hydromedusae off the Orange River Mouth, Southern Africa
(NISC (Pty) Ltd and Taylor& Francis, 2003)
A total of 242 zooplankton samples from the upper 100 m of the water column was collected discontinuously from March 1997 to January 1999 off the Orange River mouth on the west coast of southern Africa. Six species of ...
Handheld fast-track feedback instant messaging
(Telkom, 2003)
As mobile devices and networks become more data-centric, text messaging requires an extension of co-presence capabilities for better interactive discussion between input/output handicapped handheld users and their free ...
New observations on the diel vertical distribution of Hydromedusae in the southern Benguela ecosystem
(NISC (Pty) Ltd and Taylor& Francis, 2003)
Diel vertical migration (DVM) of six common species of hydromedusae was investigated during two drogue studies conducted in St Helena Bay on the west coast of South Africa in February 1995. Clytia spp., Obelia spp. and ...
Identification of a novel protein with guanylyl cyclase activity in Arabidopsis thaliana
(Elsevier, 2003)
Guanylyl cyclases (GCs) catalyze the formation of the
second messenger guanosine 3 ,5 -cyclic monophos-
phate (cGMP) from guanosine 5 -triphosphate (GTP).
While many cGMP-mediated processes in plants have
been reported, ...
The chromista
(Wiley Online, 2003)
As a group, the chromists show a diverse range of forms from tiny unicellular, flagellates to the large brown algae known as kelp. Molecular studies have confirmed the inclusion of certain organisms once considered Fungi, ...
