A rare autosomal recessive disease characterized by the deposition of copper in the BRAIN; LIVER; CORNEA; and other organs. It is caused by defects in the ATP7B gene encoding copper-transporting ATPase 2 (EC 3.6.3.4), also known as the Wilson disease protein. The overload of copper inevitably leads to progressive liver and neurological dysfunction such as LIVER CIRRHOSIS; TREMOR; ATAXIA and intellectual deterioration. Hepatic dysfunction may precede neurologic dysfunction by several years.

The evolution of the nervous system in metazoan animals has been a topic of great interest. It is thought that the first nerve cell (neuron) evolved in a common ancestor of cnidarians and bilaterians, because neuronal cell types are absent in their sister group, the sponges (Galliot et al., 2009). Although putative sensory cells do exist in the sponge, these cells do not form synapses and do not possess dendrites and axons (Richards et al., 2008). Although cnidarians typically have a diffuse nerve net, some regionalization patterns of neurons and their neurites have been identified in several types of cnidarians (Galliot et al., 2009; Watanabe et al., 2009). It is possible that these cnidarian nerve rings might represent a primitive organized nervous system. After the divergence of cnidarians and bilaterians, a centralized nervous system evolved in the bilaterian lineage (Arendt et al., 2008; Holland, 2003). The evolutionary origin of the central nervous system (CNS) in bilaterian animals has ...
THE wing surface of lepidopteran adults is covered by wing scales, which function in heat preservation, mimesis, touch, etc. (Nijhout 1991). Lepidopteran scales and Drosophila bristles are considered homologous structures on the basis of the similarities in their cell lineages and the expression of a few molecular markers (Overton 1966, 1967; Galant et al. 1998). Development of the Drosophila bristle is regulated by the basic helix-loop-helix (bHLH) transcription factors of the Achaete-Scute Complex (AS-C). Within the clusters of cells expressing achaete (ac) and scute (sc), some are selected to become sensory organ precursors, which then form and innervate the mature bristles (Skeath and Carroll 1991; Jan and Jan 1994). In ac/sc double-mutant flies, the majority of the bristles are lost; on the contrary, ectopic expression of ac and/or sc can induce extra bristles (Garcia-Bellido 1979; Campuzano et al. 1986; Balcells et al. 1988; Rodriguez et al. 1990). In the butterfly Precis coenia, the AS-C ...

ABSTRACT: Panulirus argus virus 1 (PaV1) is an unclassified, pathogenic virus first discovered in Caribbean spiny lobsters Panulirus argus from the Florida Keys, USA, and has since been confirmed in lobsters in other parts of the Caribbean. Several studies have examined the prevalence, pathogenicity, and population dynamics of the pathogen in the lobster host, but little is known about the genetic diversity of the virus. We analyzed a fragment of viral DNA from lobsters collected in the Florida Keys, which provided the first insight into the genetic diversity of PaV1. The variation in viral sequences, both within and between individual lobsters, indicates that lobsters can be infected with multiple viral strains. Laboratory experiments in which uninfected lobsters were serially exposed to lobsters inoculated with PaV1 implied that rapid mutation of strains is unlikely and suggest that there may be endemic strains of PaV1. In addition, we discovered PaV1 in P. argus postlarvae (pueruli), ...
The Caribbean spiny lobster Panulirus argus is under threat from a deadly virus. Panulirus argus 1 (PaV1) is found throughout the Caribbean, infecting up to 30% of lobsters in some areas.
We have isolated a novel Xenopus homolog of the Drosophila achaete-scute genes, called XASH-3. XASH-3 expression is neural specific and is detected as early as stage 11 1/2, making it one of the earliest markers of neural induction so far described. Moreover, XASH-3 expression within the neural plate is regionally restricted. Transverse bands of XASH-3 mRNA mark discrete positions along the anteroposterior axis, while longitudinal bands mark a discrete position along the mediolateral axis. This latter site of XASH-3 expression appears to demarcate the prospective sulcus limitans, a boundary zone that later separates the functionally distinct dorsal (alar) and ventral (basal) regions of the spinal cord. In sandwich explants lacking any underlying mesoderm, XASH-3 is expressed in longitudinal stripes located lateral to the midline. This provides the first indication that planar or midline-derived inductive signals are sufficient to establish at least some aspects of positional identity along the ...
Human sensory and motor systems provide the natural means for the exchange of information between individuals, and, hence, the basis for human civilization. The recent development of brain-computer interfaces (BCI) has provided an important element for the creation of brain-to-brain communication systems, and precise brain stimulation techniques are now available for the realization of non-invasive computer-brain interfaces (CBI). These technologies, BCI and CBI, can be combined to realize the vision of non-invasive, computer-mediated brain-to-brain (B2B) communication between subjects (hyperinteraction). Here we demonstrate the conscious transmission of information between human brains through the intact scalp and without intervention of motor or peripheral sensory systems. Pseudo-random binary streams encoding words were transmitted between the minds of emitter and receiver subjects separated by great distances, representing the realization of the first human brain-to-brain interface. In a series of
TY - JOUR. T1 - Chronic neuropathic pain. T2 - Pathomechanism and pharmacology. AU - Urban, L.. AU - Nagy, I.. AU - Bevan, S. J.. PY - 2002. Y1 - 2002. N2 - Neuropathic pain syndromes form a group of loosely connected diseases linked by the common presence of injury/damage to the peripheral sensory system and the resulting effect: chronic pain. Treatment of patients suffering from neuropathic pain is one of the most challenging clinical tasks as classical painkillers such as opioids and nonsteroidal anti-inflammatory drugs lack antinociceptive effect in these syndromes. The recent development of various animal models aided our understanding of neuropathic pain and provided targets for analgesic intervention. The discovery of abnormal, ectopic activity in injured primary afferents, sprouting of large calibre primary afferent fibres to the superficial dorsal horn, and changes in protein expression in DRG (dorsal root ganglion) cells after injury has highlighted differences between the ...
