Chemotopic representations of aromatic odorants in the rat olfactory bulb
Authors: Farahbod Haleh , Johnson Brett A. , Minami S. Sakura , Leon Michael 
Published: May 2006

AbstractOur laboratory has characterized spatial patterns of evoked neural activity across the entire glomerular layer of the rat olfactory bulb using primarily aliphatic odorants that differ systematically in functional groups and hydrocarbon structures. To represent more fully the true range of odorant chemistry, we investigated aromatic compounds, which have a more rigid molecular structure than most aliphatic compounds and are particularly salient olfactory stimuli for humans. We first investigated glomerular patterns of 2‐deoxyglucose uptake in response to aromatic compounds that differ in the nature and position of their functional groups (e.g., xylenes, trimethylbenzenes, tolualdehydes, benzaldehydes, methyl toluates, and anisaldehydes). We also studied the effects of systematic increases in the number and length of alkyl substituents. We found that most aromatic compounds activated glomeruli in the dorsal part of the bulb. Within this general area, aromatic odorants with oxygen‐containing substituents favored activation of more rostral regions, and aromatic hydrocarbons activated more posterior regions. The nature of substituents greatly affected the pattern of glomerular activation, whereas isomers differing in substitution position evoked very similar overall patterns. These relationships between the structure of aromatic compounds and their spatial representation in the bulb are contrasted with our previous findings with aliphatic odorants. J. Comp.

Thalamocortical connections of anterior and posterior parietal cortical areas in New World titi monkeys
Authors: Padberg Jeffrey , Krubitzer Leah 
Published: May 2006

AbstractWe examined the thalamocortical connections of electrophysiologically identified locations in the hand and forelimb representations in areas 3b, 1, and 5 in the New World titi monkeys (Callicebus moloch), and of area 7b/AIP. Labeled cells and terminals in the thalamus resulting from the injections were related to architectonic boundaries. As in previous studies in primates, the hand representation of area 3b has dense, restricted projections predominantly from the lateral division of the ventral posterior nucleus (VPl). Projections to area 1 were highly convergent from several thalamic nuclei including the ventral lateral nucleus (VL), anterior pulvinar (PA), VPl, and the superior division of the ventral posterior nucleus (VPs). In cortex immediately caudal to area 1, what we term area 5, thalamocortical connections were also highly convergent and predominantly from nuclei of the thalamus associated with motor, visual, or somatic processing such as VL, the medial pulvinar (PM), and PA, respectively; with moderate projections from VP, central lateral nucleus (CL), lateral posterior nucleus (LP), and VPs. Finally, thalamocortical connections of area 7b/AIP were from a range of nuclei including PA, PM, LP/LD, VL, CL, PL, and CM. The current data support two conclusions drawn from previous studies in titi monkeys and other primates. First, cortex caudal to area 1 in New World monkeys is more like area 5 than area 2. Second, the presence of thalamic input to area 5 from both motor nuclei and somatosensory nuclei of the thalamus, suggests that area 5 could be considered a highly specialized sensorimotor area. J.

The adult neural stem and progenitor cell niche is altered in amyotrophic lateral sclerosis mouse brain
Authors: Liu Zhiping , Martin Lee J. 
Published: May 2006

AbstractAmyotrophic lateral sclerosis (ALS) is a fatal adult human disease caused by motor neuron degeneration. Stem cell therapy might be a treatment for ALS. The adult mammalian forebrain has neural stem cells (NSCs) and neural progenitor cells (NPCs) in the anterior subventricular zone (SVZa), rostral migratory stream (RMS), olfactory bulb (OB) core, and dentate gyrus (DG). These cells could be used to rescue or replace degenerating upper and lower motor neurons through endogenous recruitment or autologous/allogenic transplantation. We evaluated the competency of forebrain NSCs and NPCs in transgenic (tg) mice harboring human mutant superoxide dismutase‐1 (mSOD1), a model of ALS. Tg human wild‐type SOD1 (wtSOD1) mice and non‐tg mice were controls. Bromodeoxyuridine (BrdU) labeling of cells, a marker for cell proliferation and other events, was reduced in a niche‐specific pattern in presymptomatic and symptomatic mice, with the SVZa having greater reductions than the RMS, OB, and DG. Different NSC and NPC complements were evaluated by localizing nestin, neural cell adhesion molecule, distalless‐2 transcription factor, vimentin, and glial fibrillary acidic protein. In symptomatic mice, NSC markers were reduced, whereas NPC markers were unchanged or elevated. Neurogenesis was preserved in symptomatic mSOD1 mice. NSC/NPC competence assessment in vitro revealed that mSOD1 SVZa cells had the ability to proliferate and form neurospheres but had an impaired response to mitogen stimulation. We conclude that adult mSOD1 ALS mice have abnormalities in forebrain NSCs, but the essential features of NSC/NPCs remained in presymptomatic and symptomatic mice. J. Comp.

Cu2O Nanowires in an Alumina Template: Electrochemical Conditions for the Synthesis and Photoluminescence Characteristics
Authors: Ko Eunseong , Choi Jinsub , Okamoto Koichi , Tak Yongsug , Lee Jaeyoung 
Published: May 2006

AbstractCu2O nanowires, mainly consisting of (100) and (200) polycrystalline structures with a length of 4 μm are prepared by electrochemical deposition using a porous alumina template. It is found that the optimized electrochemical conditions to prepare Cu2O nanowires are different from those for the formation of a bulk thin Cu2O layer since different pH values are found between the tip of the pores and the bulk, due to diffusion limits in porous alumina with an extremely high aspect ratio of 300. We point out that Cu2O (200), Cu2O (111), Cu, and co‐deposited alloys can be obtained under specific electrochemical conditions. In addition, the optical band gap of the prepared Cu2O nanowires with a length of 4 μm and a diameter of 200 nm is estimated to be 2.17 eV from photoluminescence measurements.
Ana and the Internet: A review of pro‐anorexia websites
Authors: Norris Mark L. , Boydell Katherine M. , Pinhas Leora , Katzman Debra K. 
Published: May 2006

AbstractObjective:The purpose of this article is to describe the content of pro‐anorexia websites, both qualitatively and quantitatively.Method:An Internet search protocol was developed to identify pro‐anorexia websites. A grounded theory approach was used to generate themes from Internet‐based information. Basic descriptive analysis was employed to report on key website characteristics.Results:Twenty pro‐anorexia websites met inclusion criteria. Saturation of themes was achieved after review of 12 websites. Key website characteristics included purpose of website (75%), information about webmaster (67%), website disclaimers (58%), and information on “tips and tricks” (67%). Religious metaphors, lifestyle descriptions, and “thinspiration” (inspirational photo galleries and quotes that aim to serve as motivators for weight loss) were frequently present. A total of 10 themes were generated. The most prevalent themes included control, success, and perfection.Conclusion:Health‐care providers and caregivers should be aware of pro‐anorexia websites and their content, as these websites contain information that promote and support anorexia nervosa. © 2006 by Wiley Periodicals, Inc.

The Stereochemistry of Allenic Enol Tautomerism – Independent Generation and Reactivity of the Enolates
Authors: Zimmerman Howard E. , Pushechnikov Alexei 
Published: May 2006

AbstractA priori, allenic enolates as reaction intermediates may be protonated to afford (Z)‐ or (E)‐α,β‐unsaturated carbonyl products. The allenic enolates are tautomeric with α‐vinylcarbanions. The literature on the behavior of these species on protonation is highly varied both in stereochemical outcome and in mechanistic interpretation. The current study has provided an independent mode of generation of the allenic enolates and has investigated the reaction stereochemistry of protonation to afford the stereoisomeric α,β‐unsaturated carbonyl products. Under kinetic conditions, these highly reactive species are protonated in the α,β‐π plane with preference (E) to the larger β group. Under thermodynamic conditions, addition/elimination equilibrates the two product stereoisomers. The kinetic protonation stereochemistry is a function of solvent, proton donor, and donor concentration. Computations serve to clarify the reaction mechanism. It was found that the stereochemistry of ketonization of allenic enolates follows the reaction course suggested as possible some decades earlier and common to less unique enolates. Additionally, the linear versus the bent enolate structure proves to depend on the countercation.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
Actual, ideal, and expected relatedness with parents across and within cultures
Authors: Imamoğlu E. Olcay , Karakitapoğlu‐Aygün Zahide 
Published: May 2006

AbstractDifferences in actual, ideal, and expected relatedness with mothers and fathers were explored across two cultural groups (i.e., university students from the U.S. and Turkey) in Study 1, and across two socioeconomic status (SES) groups (i.e., high school students from the upper and lower SES in Turkey) in Study 2. In both studies associations of perceived relatedness with individualistic and collectivistic value orientations as well as with self‐construal types were also explored. Results indicated cultural groups to be quite similar in actual relatedness, but to differ in expected and ideal relatedness, with Turks reporting more relatedness. In Turkey, lower SES adolescents reported more relatedness in ideal and actual conditions than upper SES adolescents, while they did not differ in expected relatedness. Results involving self‐types and value orientations pointed to both cross‐cultural similarities and within‐cultural diversity in relatedness. Theoretical implications of the differential impact of culture, SES, self‐construals, and value orientations on actual, ideal, and expected relatedness are discussed.

Construction of a Highly Selective and Sensitive La(III) Sensor Based on N‐(2‐Pyridyl)‐N′‐(4‐methoxyphenyl)‐thiourea for Nano Level Monitoring of La(III) Ions
Authors: Ganjali M. R. , Norouzi P. , Alizadeh T. , Tadjarodi A. , Hanifehpour Y. 
Published: May 2006

AbstractN‐(2‐Pyridyl)‐N′‐(4‐methoxyphenyl)‐thiourea (PMPT) was found to be a suitable neutral ion carrier for the construction of a highly selective and sensitive La(III) membrane sensor. Poly(vinyl chloride) (PVC) based membranes of PMPT with potassium tetrakis (p‐chlorophenyl) borate (KTpClPB) as an anionic excluder and oleic acid (OA), dibutyl phthalate (DBP), benzyl acetate (BA) and o‐nitrophenyloctyl ether (NPOE) as plasticizing solvent mediators were constructed and investigated as La(III) membrane sensors. A membrane composed of PMPT‐PVC‐KTpClPB‐BA with the ratio 8.0 : 35.0 : 3.0 : 54.0 works well over a very wide concentration range (4.0×10−8 to 1.0×10−1 M) with a Nernstian slope of 19.6±0.2 mV per decade of activity between pH values of 4.0 and 9.0. The detection limit of the sensor was calculated to be 2.0×10−8 M (ca. 3.0 ppb). The sensor displays very good discrimination toward La(III) ions with regard to most common metal ions and lanthanide ions. The proposed sensor shows a short response time for whole concentration range (ca. 12 s). For evaluation of the analytical applicability of the La(III) sensor, it was successfully used as an indicator electrode for the titration of La(III) ions with EDTA. It was also applied to the determination of fluoride content of two mouth wash preparation samples and monitoring of La(III) ions in some binary and ternary mixtures.
