Astrocytes are organized as networks of communicating cells due to their high expression level of connexins, the molecular constituents of gap junction channels. Based on their permeability properties for ions and small signaling molecules such astroglial wiring interferes with neuronal activity and survival. In this paper, I identify and discuss which future technical and conceptual progress o...
The aim of this article is to present a possible teaching-research-innovation synergy framework that may work for one University of Technology (UoT) that is moving towards becoming an entrepreneurial university in order to bring about practical solutions for the socio-economic needs of the surrounding communities. A literature review was undertaken to interrogate the possibility of applying the...
This paper investigates the relationship between tariff and growth in the Australian economy over the period from 1871 to 2002. The study is motivated by the debate on the apparent ‘tariff-growth paradox’, a sign switch in the link between tariff rate and growth between the first and second episodes of globalization in world history, established from cross-country growth regressions. The long a...
Rare mitochondrial lineages with relict distributions can sometimes be disproportionately informative about deep events in human prehistory. We have studied one such lineage, haplogroup R0a, which uniquely is most frequent in Arabia and the Horn of Africa, but is distributed much more widely, from Europe to India. We conclude that: (1) the lineage ancestral to R0a is more ancient than previousl...
Dendritic spines in glomeruli of the inferior olive are coupled by gap junctions and receive both inhibitory and excitatory inputs. In this issue of Neuron, Lefler et al. (2014), Mathy et al. (2014), and Turecek et al. (2014) provide new insight into how these inputs modulate electrical coupling and oscillatory activity.
The disappearance and reappearance of rat liver gap junctions with respect to the time elapsed after partial hepatectomy and the location in the liver acinar zones were analysed immunohistochemically and morphometrically using an affinity purified antibody against the rat liver gap junction protein. The specificity of antibody was assessed by comparing the immunofluorescent staining patterns of...
Providing clean water and sufficient affordable energy to all without compromising the environment is a key priority in the scientific community. Many recent studies have focused on carbon-based devices in the hope of addressing this grand challenge, justifying and motivating detailed studies of water in contact with carbonaceous materials. Such studies are becoming increasingly important becau...
Introduction The Millennium Development Goals laid out an ambitious agenda to improve living standards in poor countries. Now, with the Sustainable Development Goals, world leaders are aiming to set a broader agenda for 2015 and beyond: a set of universal goals that engages countries at all income levels to ensure the long-term well-being of humankind. Put another way, while the MDGs aimed to l...
There has emerged in the Western economies a strong nexus between the credit risks of fi nancial sectors and their sovereigns. We argue that this phenomenon can be understood in the context of two debt overhang problems: one affecting the fi nancial sector due to its under-capitalisation following the crisis of 2007-08; the second, affecting the non-fi nancial sector, whose incentives are crowd...
BACKGROUND In the wake of collapse of the Soviet Union, Central Asia has transformed into a key hub along the Afghan opiates trafficking routes. Around 30 percent of the heroin manufactured in Afghanistan is estimated to be smuggled through Central Asian republics in its way to booming drug markets in Russia and Eastern Europe. METHODS Building upon available evidence and extensive fieldwork ...
