AbstractHerein we describe the synthesis and conformational analysis of a series of bicyclic thymidine derivatives and their evaluation as inhibitors of thymidine monophosphate kinase from Mycobacterium tuberculosis (TMPKmt), based on previously discovered bicyclic sugar nucleosides. With a Ki value of 2.3 μm, 1‐[3‐aminomethyl‐3,5‐dideoxy‐2‐O,6‐N‐(thiocarbonyl)‐β‐D‐ribofuranosyl]thymine emerged as the most potent TMPK inhibitor of this series. Moreover, this promising compound displays inhibitory potency against Mycobacteria cultures with an IC99 value of 100 μg mL−1, thus promoting TMPKmt for the first time as a validated target for further inhibitory design. Attempts to rationalise the observed structure–activity relationship (SAR) involving molecular modelling and conformational analysis are described.
Phylogeny of a serotonin‐immunoreactive neuron in the primary olfactory center of the insect brain
Authors: Dacks Andrew M. , Christensen Thomas A. , Hildebrand John G. 
Published: August 2006

AbstractSerotonin (5‐hydroxytryptamine; 5HT) functions in insects as a neurotransmitter, neuromodulator, and neurohormone. In the sphinx moth Manduca sexta, each of the paired antennal lobes (ALs; the primary olfactory centers in the insect brain) has one 5HT‐immunoreactive (5HT‐ir) neuron that projects into the protocerebrum, crosses the posterior midline, and innervates the contralateral AL; this is referred to as the contralaterally projecting, serotonin‐immunoreactive deutocerebral (CSD) neuron. These neurons are thought to function as centrifugal modulators of olfactory sensitivity. To examine the phylogenetic distribution of 5HT‐ir neurons apparently homologous to the CSD neuron, we imaged 5HT‐like immunoreactivity in the brains of 40 species of insects belonging to 38 families in nine orders. CSD neurons were found in other Lepidoptera, Trichoptera, Diptera, Coleoptera, and Neuroptera but not in the Hymenoptera. In the paraneopteran and polyneopteran species (insects that undergo incomplete metamorphosis) examined, AL 5HT neurons innervate the ispsilateral AL and project to the protocerebrum. Our findings suggest that the characteristic morphology of the CSD neurons originated in the holometabolous insects (those that undergo complete metamorphosis) and were lost in the Hymenoptera. In a subset of the Diptera, the CSD neurons branch within the contralateral AL and project back to the ipsilateral AL via the antennal commissure. The evolution of AL 5HT neurons is discussed in the context of the physiological actions of 5HT observed in the lepidopteran AL. J. Comp. Neurol. 498:727–746, 2006. © 2006 Wiley‐Liss, Inc.
Subcellular distribution of M2 muscarinic receptors in relation to dopaminergic neurons of the rat ventral tegmental area
Authors: Garzón Miguel , Pickel Virginia M. 
Published: August 2006

AbstractAcetylcholine can affect cognitive functions and reward, in part, through activation of muscarinic receptors in the ventral tegmental area (VTA) to evoke changes in mesocorticolimbic dopaminergic transmission. Among the known muscarinic receptor subtypes present in the VTA, the M2 receptor (M2R) is most implicated in autoregulation and also may play a heteroreceptor role in regulation of the output of the dopaminergic neurons. We sought to determine the functionally relevant sites for M2R activation in relation to VTA dopaminergic neurons by examining the electron microscopic immunolabeling of M2R and the dopamine transporter (DAT) in the VTA of rat brain. The M2R was localized to endomembranes in DAT‐containing somatodendritic profiles but showed a more prominent, size‐dependent plasmalemmal location in nondopaminergic dendrites. M2R also was located on the plasma membrane of morphologically heterogenous axon terminals contacting unlabeled as well as M2R‐ or DAT‐labeled dendrites. Some of these terminals formed asymmetric synapses resembling those of cholinergic terminals in the VTA. The majority, however, formed symmetric, inhibitory‐type synapses or were apposed without recognized junctions. Our results provide the first ultrastructural evidence that the M2R is expressed, but largely not available for local activation, on the plasma membrane of VTA dopaminergic neurons. Instead, the M2R in this region has a distribution suggesting more indirect regulation of mesocorticolimbic transmission through autoregulation of acetylcholine release and changes in the physiological activity or release of other, largely inhibitory transmitters. These findings could have implications for understanding the muscarinic control of cognitive and goal‐directed behaviors within the VTA. J. Comp. Neurol. 498:821–839, 2006. © 2006 Wiley‐Liss, Inc.

AbstractThe MRL mouse is unique in its capacity for regenerative healing of wounds. This regenerative ability includes complete closure, with little scarring, of wounds to the ear pinna and repair of cardiac muscle, without fibrosis, following cryoinjury. Here, we examine whether neurogenic zones within the MRL brain show enhanced regenerative capacity. The largest neurogenic zone in the adult brain, the subventricular zone (SVZ), lies adjacent to the lateral wall of the lateral ventricle and is responsible for replacement of interneuron populations within the olfactory bulb. Initial gross observation of the anterior forebrain in MRL mice revealed enlarged lateral ventricles; however, little neurodegeneration was detected within the SVZ or surrounding tissues. Instead, increased proliferation within the SVZ was observed, based on incorporation of the thymidine analogue bromodeoxyuridine. Closer examination using electron microscopy revealed that a significant number of SVZ astrocytes interpolated within the ependyma and established contact with the ventricle. In addition, subependymal, protuberant nests of cells, consisting primarily of neuroblasts, were found along the anterior SVZ of MRL mice. Whole mounts of the lateral wall of the lateral ventricle stained for the neuroblast marker doublecortin revealed normal formation of chains of migratory neuroblasts along the entire wall and introduction of enhanced green fluorescent protein‐tagged retrovirus into the lateral ventricles confirmed that newly generated neuroblasts were able to track into the olfactory bulb.

Development of Multiwafer Warm‐Wall Planetary VPE Reactors for SiC Device Production
Authors: Burk A. A. 
Published: August 2006

AbstractThe development of SiC vapor phase epitaxial (VPE) growth for advanced SiC device production is reviewed with an emphasis on multiwafer reactors. Initially SiC epitaxial growth was performed in small homemade reactors on tiny, several millimeter on a side SiC crystals. While interest in SiC has its origins in the late 1950s, along side the elemental semiconductors Si and Ge, its technological development has been delayed by the extreme temperatures (∼1600 °C) required to grow SiC epitaxial layers, the late development of suitable substrates, and the various polytypes that can form. In large part these challenges have now been overcome. The most recent SiC epitaxial layer growth results, including those from the highest reported throughput, 8 × 100 mm, warm‐wall planetary SiC‐VPE reactor, are presented in detail. The growth of device‐quality SiC epitaxial layers with low background doping concentrations <1 × 1014cm–3, and intentional p‐ and n‐type doping from ∼1 × 1015 cm–3to >1 × 1019cm—3will be described. These layers have intrawafer thickness and n‐type doping uniformity (σ/mean) of ∼2 % and ∼8 %. The total range of the average intrawafer thickness and doping within a run are approximately ±1 % and ±6 %, respectively. Long term run‐to‐run variations (σ/mean) while under process control are currently ∼3 % for thickness and ∼5 % for doping. Multiwafer SiC epitaxial layer throughput has been increased by over a factor of twenty in just the past seven years while achieving these desirable layer characteristics. This new epitaxial capability is enabling the economical production of advanced SiC devices for the marketplace.
CVD Growth of 3C‐SiC on 4H/6H Mesas

AbstractThis article describes growth and characterization of the highest quality reproducible 3C‐SiC heteroepitaxial films ever reported. By properly nucleating 3C‐SiC growth on top of perfectly on‐axis (0001) 4H‐SiC mesa surfaces completely free of atomic scale steps and extended defects, growth of 3C‐SiC mesa heterofilms completely free of extended crystal defects can be achieved. In contrast, nucleation and growth of 3C‐SiC mesa heterofilms on top of 4H‐SiC mesas with atomic‐scale steps always results in numerous observable dislocations threading through the 3C‐SiC epilayer. High‐resolution X‐ray diffraction (HRXRD) and high resolution cross‐sectional transmission electron microscopy (HRXTEM) measurements indicate non‐trivial, in‐plane, lattice mismatch between the 3C and 4H layers. This mismatch is somewhat relieved in the step‐free mesa case via misfit dislocations confined to the 3C/4H interfacial region without dislocations threading into the overlying 3C‐SiC layer. These results indicate that the presence or absence of steps at the 3C/4H heteroepitaxial interface critically impacts the quality, defect structure, and relaxation mechanisms of single‐crystal heteroepitaxial 3C‐SiC films.
