Chelant‐assisted Phytostabilization of Paint‐contaminated Residential Sites
Authors: Andra Syam S. , Sarkar Dibyendu , Saminathan Sumathi K. M. , Datta Rupali 
Published: August 2010

AbstractFollowing the basic incubation study, a greenhouse experiment was conducted to elucidate the efficiency of vetiver grass (Vetiveria zizanioides L.), with or without chelating agents, in remediating lead (Pb)‐contaminated soils from actual residential sites where Pb‐based paints were used. Because the primary factor affecting Pb phytoavailability in soils is soil pH, we used two soil types widely varying in pH that have total Pb concentrations above 1500 mg kg−1 soil. Lead‐contaminated, low pH, acidic soils were collected from residential sites in Baltimore, MD and high pH, alkaline soils were collected from residential sites in San Antonio, TX. Based on the soil characterization results, two most appropriate soils (one from each city, having similar Pb levels but variable soil physico‐chemical properties) were selected for this study. Ethylenediaminetetraacetic acid (EDTA) and [S,S′]ethylenediaminedisuccinate (EDDS) were applied at 5, 10, and 15 mmol kg−1 soil. Lead uptake and translocation in vetiver was determined on day 10 after chelants addition. Plant and soil analysis show that EDTA treated soils have maximum Pb uptake and lower total soil Pb levels. Prediction models developed for exchangeable Pb show a strong correlation for total Pb accumulated in vetiver grass. Results of the sequential chemical extraction of the soils at both initial and final time‐points, indicates a significant mobilization of Pb by the two chelants from carbonate‐bound fraction to exchangeable pool. Information on physico‐chemical properties of contaminated residential soils help in predicting Pb phytoextraction and thus further help in calibrating a successful chelant‐assisted phytoremediation model.
How to measure the transmetallation of a gadolinium complex
Authors: Laurent S. , Vander Elst L. , Henoumont C. , Muller R. N. 
Published: August 2010

AbstractThe suitability of paramagnetic complexes as contrast agents depends not only on their relaxivity but also on their stability and inertness towards transmetallation processes by endogenous ions. In this work, we describe a convenient method to study the stability of paramagnetic Gd complexes through the evolution of the paramagnetic longitudinal relaxation rate of water protons at 37 °C.

Neuroanatomy of the complex tibial organ in the splay‐footed cricket Comicus calcaris Irish 1986 (Orthoptera: Ensifera: Schizodactylidae)
Authors: Strauß Johannes , Lakes‐Harlan Reinhard 
Published: August 2010

AbstractThe subgenual chordotonal organ complex in insects is modified in ensiferan taxa like Gryllidae and Tettigoniidae into hearing organs with specific sets of auditory receptors. Here, this sensory organ complex is documented in the nonhearing splay‐footed cricket Comicus calcaris. The tibial chordotonal organ consists of three parts: the subgenual organ, the intermediate organ, and the crista acustica homolog. The latter is an array of linearly organized neurons homologous to auditory receptors in the tibial hearing organs of Tettigoniidae. The tibial organ is structurally similar in all three leg pairs, with similar neuron numbers in the fore‐ and midleg, but lower numbers in the hindleg. The foreleg crista acustica homolog consists of 34 ± 4 neurons, the highest number in an atympanate Ensiferan. Additionally, an accessory chordotonal organ with 15 ± 5 neurons innervated by nerve 5B1 is present in the foreleg. The central projection of the tibial organreveals ipsilateral sensory terminals in the primary sensory neuropil, the medial ventral association center with terminations close to the midline. As determined from extracellular recordings, the entire tibial organ is vibrosensitive. The organization of the tibial organ is compared to other ensiferan auditory and nonauditory tibial organs. Spatial orientation of neurons in the crista acustica homolog is not reminiscent of auditory structures, and the neuroanatomy is discussed with respect to stridulation behavior and the evolutionary origin of hearing in Ensifera.

Delayed appearance of the scaffolding proteins PSD‐95 and homer‐1 at the developing rat calyx of held synapse
Authors: Soria Van Hoeve John S. , Borst J. Gerard G. 
Published: August 2010

AbstractThe calyx of Held synapse is a giant axosomatic synapse that acts as a fast relay in the sound localization circuit of the brainstem. In rodents it forms within a relatively brief period starting around the second postnatal day (P2). The relative timing of the formation of its pre‐ and the postsynaptic compartment are not yet known. By means of fluorescent immunohistochemistry in neonatal rats we therefore compared the developmental expression patterns of the vesicular glutamate transporter (VGLUT)‐1 and the postsynaptic density scaffolding proteins Homer‐1 and PSD‐95 in the medial nucleus of the trapezoid body (MNTB). Before its formation, colocalized punctate staining of VGLUT‐1 and Homer‐1 or PSD‐95 was observed on principal neurons, in agreement with earlier work showing that they are already innervated by fibers from the cochlear nucleus before the calyx forms. The expression of VGLUT‐1 clusters within the nascent calyx of Held synapse preceded the expression of Homer‐1 and PSD‐95 clusters, as indicated by the presence of principal neurons with only a large contiguous cluster (LCC) of VGLUT‐1 at P2‐3, whereas no neurons with only an LCC for Homer‐1 or PSD‐95 were seen. At P3 the first principal neurons with both a pre‐ and a postsynaptic LCC were observed, and at P12 all principal neurons had both a pre‐ and a postsynaptic LCC. The relatively late appearance of Homer‐1 and PSD‐95 within the developing calyx of Held synapse suggests that they play a role in its stabilization and the recruitment of additional receptors to its postsynaptic density.

Experience‐induced plasticity of thalamocortical axons in both juveniles and adults
Authors: Wimmer Verena C. , Broser Philip J. , Kuner Thomas , Bruno Randy M. 
Published: August 2010

AbstractWe examined the effect of sensory deprivation on thalamocortical (TC) projections to the rat primary somatosensory cortex at different postnatal ages ranging from P0 to P96. Rats had their whiskers clipped off with one or two vibrissae spared. TC axons innervating barrel cortex were specifically labeled by injecting virus expressing fluorescent proteins into the corresponding primary (VPM) and/or secondary (POm) thalamic nuclei. The density of VPM axons in deprived columns was ≈34% lower relative to spared columns with a concomitant decrease in bouton density, suggesting a deprivation‐induced retraction of VPM axons. Axonal changes were reversible upon regrowth of the clipped whiskers and independent of age at deprivation, indicating the absence of a critical period for anatomical plasticity. The POm projection was not obviously altered by sensory deprivation. We suggest that retraction and regrowth of TC axons substantially contribute to long‐term deprivation‐dependent functional plasticity. J. Comp. Neurol. 518:4629–4648, 2010. © 2010 Wiley‐Liss, Inc.
Axonal branching patterns of nucleus accumbens neurons in the rat
Authors: Tripathi Anushree , Prensa Lucía , Cebrián Carolina , Mengual Elisa 
Published: August 2010

AbstractThe patterns of axonal collateralization of nucleus accumbens (Acb) projection neurons were investigated in the rat by means of single‐axon tracing techniques using the anterograde tracer biotinylated dextran amine. Seventy‐three axons were fully traced, originating from either the core (AcbC) or shell (AcbSh) compartment, as assessed by differential calbindin D28k‐immunoreactivity. Axons from AcbC and AcbSh showed a substantial segregation in their targets; target areas were either exclusively or preferentially innervated from AcbC or AcbSh. Axon collaterals in the subthalamic nucleus were found at higher than expected frequencies; moreover, these originated exclusively in the dorsal AcbC. Intercompartmental collaterals were observed from ventral AcbC axons into AcbSh, and likewise, interconnections at pallidal and mesencephalic levels were also observed, although mostly from AcbC axons toward AcbSh targets, possibly supporting crosstalk between the two subcircuits at several levels. Cell somata giving rise to short‐range accumbal axons, projecting to the ventral pallidum (VP), were spatially intermingled with others, giving rise to long‐range axons that innervated VP and more caudal targets. This anatomical organization parallels that of the dorsal striatum and provides the basis for possible dual direct and indirect actions from a single axon on either individual or small sets of neurons.

Differential distribution of neurons in the gyral white matter of the human cerebral cortex
Authors: García‐Marín V. , Blazquez‐Llorca L. , Rodriguez J.R. , Gonzalez‐Soriano J. , DeFelipe J. 
Published: August 2010

AbstractThe neurons in the cortical white matter (WM neurons) originate from the first set of postmitotic neurons that migrates from the ventricular zone. In particular, they arise in the subplate that contains the earliest cells generated in the telencephalon, prior to the appearance of neurons in gray matter cortical layers. These cortical WM neurons are very numerous during development, when they are thought to participate in transient synaptic networks, although many of these cells later die, and relatively few cells survive as WM neurons in the adult. We used light and electron microscopy to analyze the distribution and density of WM neurons in various areas of the adult human cerebral cortex. Furthermore, we examined the perisomatic innervation of these neurons and estimated the density of synapses in the white matter. Finally, we examined the distribution and neurochemical nature of interneurons that putatively innervate the somata of WM neurons. From the data obtained, we can draw three main conclusions: first, the density of WM neurons varies depending on the cortical areas; second, calretinin‐immunoreactive neurons represent the major subpopulation of GABAergic WM neurons; and, third, the somata of WM neurons are surrounded by both glutamatergic and GABAergic axon terminals, although only symmetric axosomatic synapses were found. By contrast, both symmetric and asymmetric axodendritic synapses were observed in the neuropil. We discuss the possible functional implications of these findings in terms of cortical circuits. J.

Neuroprotective effects of testosterone in a naturally occurring model of neurodegeneration in the adult avian song control system
Authors: Thompson Christopher K. , Brenowitz Eliot A. 
Published: August 2010

AbstractSeasonal regression of the avian song control system, a series of discrete brain nuclei that regulate song learning and production, serves as a useful model for investigating the neuroprotective effects of steroids. In seasonally breeding male songbirds, the song control system regresses rapidly when males are transferred from breeding to nonbreeding physiological conditions. One nucleus in particular, the HVC, regresses in volume by 22% within days of castration and transfer to a nonbreeding photoperiod. This regression is mediated primarily by a 30% decrease in neuron number, a result of a caspase‐dependent process of programmed cell death. Here we examine whether testosterone (T) can act locally in the brain to prevent seasonal‐like neurodegeneration in HVC. We began to infuse T intracerebrally near HVC on one side of the brain in breeding‐condition male white‐crowned sparrows 2 days prior to T withdrawal and shifting them to short‐day photoperiods. The birds were killed 3 or 7 days later. Local T infusion significantly protected ipsilateral HVC from volume regression and neuron loss. In addition, T infusion significantly reduced the number, density, and number/1,000 neurons of activated caspase‐3 cells and cells positive for cleaved PARP, both markers for programmed cell death, in the ipsilateral HVC. T infusion near HVC also prevented regression of ipsilateral efferent targets of HVC neurons, including the volumes of robust nucleus of the arcopallium (RA) and Area X and the soma area and density of RA neurons. Thus T can act locally in the brain to have a neuroprotective effect and act transsynaptically to prevent regression of efferent nuclei. J. Comp. Neurol. 518:4760–4770, 2010. © 2010 Wiley‐Liss, Inc.
Differential postsynaptic compartments in the laterocapsular division of the central nucleus of amygdala for afferents from the parabrachial nucleus and the basolateral nucleus in the rat
Authors: Dong Yu‐Lin , Fukazawa Yugo , Wang Wen , Kamasawa Naomi , Shigemoto Ryuichi 
Published: August 2010

AbstractNeurons in the laterocapsular division of the central nucleus of the amygdala (CeC), which is known as the “nociceptive amygdala,” receive glutamatergic inputs from the parabrachial nucleus (PB) and the basolateral nucleus of amygdala (BLA), which convey nociceptive information from the dorsal horn of the spinal cord and polymodal information from the thalamus and cortex, respectively. Here, we examined the ultrastructural properties of PB– and BLA–CeC synapses identified with EGFP‐expressing lentivirus in rats. In addition, the density of synaptic AMPA receptors (AMPARs) on CeC neurons was studied by using highly sensitive SDS‐digested freeze‐fracture replica labeling (SDS‐FRL). Afferents from the PB made asymmetrical synapses mainly on dendritic shafts (88%), whereas those from the BLA were on dendritic spines (81%). PB–CeC synapses in dendritic shafts were significantly larger (median 0.072 μm2) than BLA–CeC synapses in spines (median 0.058 μm2; P = 0.02). The dendritic shafts that made synapses with PB fibers were also significantly larger than those that made synapses with BLA fibers, indicating that the PB fibers make synapses on more proximal parts of dendrites than the BLA fibers. SDS‐FRL revealed that almost all excitatory postsynaptic sites have AMPARs in the CeC. The density of AMPAR‐specific gold particles in individual synapses was significantly higher in spine synapses (median 510 particles/μm2) than in shaft synapses (median 427 particles/μm2; P = 0.01). These results suggest that distinct synaptic impacts from PB– and BLA–CeC pathways contribute to the integration of nociceptive and polymodal information in the CeC. J. Comp.
