Comparison of the distributions of urocortin‐containing and cholinergic neurons in the perioculomotor midbrain of the cat and macaque
Authors: May Paul J. , Reiner Anton J. , Ryabinin Andrey E. 
Published: January 2008

AbstractUrocortin is a novel neurotransmitter that appears to play a role in eating and drinking behavior. Most urocortin‐positive (urocortin+) neurons in rodents are found in the cytoarchitecturally defined Edinger‐Westphal nucleus (EW). However, the EW is traditionally described as the source of the preganglionic parasympathetic outflow to the ciliary ganglion. We examined the distribution of urocortin+ cells and motoneurons by use of immunohistochemical staining for this peptide and for choline acetyltransferase (ChAT) in macaque monkeys, in which most preganglionic motoneurons inhabit the EW, and in cats, in which most do not. In both species, lack of overt double labeling indicated that the ChAT+ and urocortin+ cells are separate populations. In the monkey, most nonoculomotor ChAT+ neurons were found within the EW. In contrast, urocortin+ cells were distributed mainly between the oculomotor nuclei and in the supraoculomotor area. In the cat, most nonoculomotor ChAT+ cells were located in the supraoculomotor area and anteromedian nucleus. Few were present in the cat EW. Instead, this nucleus was filled with urocortin+ cells. These results highlight the fact the term EW has come to indicate different nuclei in different species. Consequently, we have adopted the identifiers preganglionic (EWPG) and urocortin‐containing (EWU) to designate the cytoarchitecturally defined EW nuclei in monkeys and cats, respectively. Furthermore, we propose a new open‐ended nomenclature for the perioculomotor (pIII) cells groups that have distinctive projections and neurochemical signatures. This will allow more effective scientific discourse on the connections and function of groups such as the periculomotor urocortin (pIIIU) and preganglionic (pIIIPG) populations. J. Comp.

Calcitonin receptor‐like receptor (CLR), receptor activity‐modifying protein 1 (RAMP1), and calcitonin gene‐related peptide (CGRP) immunoreactivity in the rat trigeminovascular system: Differences between peripheral and central CGRP receptor distribution
Authors: Lennerz Jochen K. , Rühle Victor , Ceppa Eugene P. , Neuhuber Winfried L. , Bunnett Nigel W. , Grady Eileen F. , Messlinger Karl 
Published: January 2008

AbstractCalcitonin gene‐related peptide (CGRP) is a key mediator in primary headaches including migraine. Animal models of meningeal nociception demonstrate both peripheral and central CGRP effects; however, the target structures remain unclear. To study the distribution of CGRP receptors in the rat trigeminovascular system we used antibodies recognizing two components of the CGRP receptor, the calcitonin receptor‐like receptor (CLR) and the receptor activity‐modifying protein 1 (RAMP1). In the cranial dura mater, CLR and RAMP1 immunoreactivity (‐ir) was found within arterial blood vessels, mononuclear cells, and Schwann cells, but not sensory axons. In the trigeminal ganglion, besides Schwann and satellite cells, CLR‐ and RAMP1‐ir was found in subpopulations of CGRP‐ir neurons where colocalization of CGRP‐ and RAMP1‐ir was very rare (≈0.6%). CLR‐ and RAMP1‐ir was present on central, but not peripheral, axons. In the spinal trigeminal nucleus, CLR‐ and RAMP1‐ir was localized to “glomerular structures,” partly colocalized with CGRP‐ir. However, CLR‐ and RAMP1‐ir was lacking in central glia and neuronal cell bodies. We conclude that CGRP receptors are associated with structural targets of known CGRP effects (vasodilation, mast cell degranulation) and targets of unknown function (Schwann cells). In the spinal trigeminal nucleus, CGRP receptors are probably located on neuronal processes, including primary afferent endings, suggesting involvement in presynaptic regulation of nociceptive transmission. Thus, in the trigeminovascular system CGRP receptor localization suggests multiple targets for CGRP in the pathogenesis of primary headaches. J. Comp.

Numerical simulation on operation of closed‐loop experimental facility with subsonic MHD generator
Authors: Takana Hidemasa , Okuno Yoshihiro , Yamasaki Hiroyuki 
Published: January 2008

AbstractThe operating characteristics and operation procedure of the closed‐loop experimental facility under subsonic power generation have been investigated by means of time‐dependent quasi‐one‐dimensional numerical simulations. Two ways of operation for subsonic power generation were found: (1) subsonic operation both under nonpower and power generation and (2) supersonic operation under nonpower generation and subsonic operation under power generation. For operation (1), Mach number at channel inlet decreases to ∼0.6, therefore it is required to generate plasma under this Mach number. On the other hand, if the plasma cannot be generated, operation (2) needs to be carried out. In this case, a shock wave appears in the generator channel, then the influence of a large pressure change and a vibration caused by a shock wave in the generator channel needs to be considered. © 2008 Wiley Periodicals, Inc.

Position sensorless control for ultrasonic motors based on input voltage information
Authors: Senjyu Tomonobu , Yoshida Tomohiro , Nakamura Mitsuru , Urasaki Naomitsu , Funabashi Toshihisa , Sekine Hideomi 
Published: January 2008

AbstractThis paper presents a method of position sensorless control of ultrasonic motors (USM). The position sensorless control method is useful for reducing the cost and size of drive system. The position estimation method is based on the input voltage information of the ultrasonic motor. The characteristic of input voltage versus rotor position is expressed by a quadratic function which is used to estimate a rotor position based on input voltage information. This estimation method, which uses only the drive voltage of the ultrasonic motor, is a very simple algorithm and shows good estimation ability. The parameters of the quadratic function are adjusted by using the recursive least squares method and are obtained on‐line. Since it can correspond to parameter change, the estimated rotor position shows good agreement with the measured rotor position against load torque and motor temperature changes. Sensorless position control is achieved by using the estimated rotor position instead of the measured rotor position. The validity of the proposed method is confirmed by experimental results. © 2008 Wiley Periodicals, Inc.

Monitoring gasoline blending rates for compliance
Authors: Gill Ryan S. , Keating Jerome P. 
Published: January 2008

AbstractWe consider the problem of obtaining a confidence region for the blending coefficient in the blended underground storage tank (UST) leak model. Under this model, the blending coefficient estimator is a ratio of two correlated normal random variables. Fieller's method provides a simple way of obtaining limits with exact coverage probability. This confidence interval can be inverted to test the hypothesis that the advertised blending ratio is correct. This method is applied to the Cary blended site data, and several variations are included to account for outliers and a change point. Copyright © 2008 John Wiley & Sons, Ltd.
Hedging under counterparty credit uncertainty
Authors: Mahul Olivier , David Cummins J. 
Published: January 2008

AbstractThis study investigates optimal production and hedging decisions for firms facing price risk that can be hedged with vulnerable contracts, i.e., exposed to nonhedgeable endogenous counterparty credit risk. When vulnerable forward contracts are the only hedging instruments available, the firm's optimal level of production is lower than without credit risk. Under plausible conditions on the stochastic dependence between the commodity price and the counterparty's assets, the firm does not sell its entire production on the vulnerable forward market. When options on forward contracts are also available, the optimal hedging strategy requires a long put position. This provides a new rationale for the hedging role of options in the over‐the‐counter markets exposed to counterparty credit risk. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28: 248–263, 2008
In vitro neuronal and glial differentiation from embryonic or adult neural precursor cells are differently affected by chronic or acute activation of microglia
Authors: Cacci Emanuele , Ajmone‐Cat Maria Antonietta , Anelli Tonino , Biagioni Stefano , Minghetti Luisa 
Published: January 2008

AbstractThe contribution of microglia to the modulation of neurogenesis under pathological conditions is unclear. Both pro‐ and anti‐neurogenic effects have been reported, likely reflecting the complexity of microglial activation process. We previously demonstrated that prolonged (72 hr) in vitro exposure to lipopolysaccharide (LPS) endows microglia with a potentially neuroprotective phenotype, here referred as to “chronic”. In the present study we further characterized the chronic phenotype and investigated whether it might differently regulate the properties of embryonic and adult neural precursor cells (NPC) with respect to the “acute” phenotype acquired following a single (24 hr) LPS stimulation. We show that the LPS‐dependent induction of the proinflammatory cytokines interleukin (IL)‐1α, IL‐1β, IL‐6, and tumor necrosis factor (TNF)‐α was strongly reduced after chronic stimulation of microglia, as compared with acute stimulation. Conversely, the synthesis of the anti‐inflammatory cytokine IL‐10 and the immunomodulatory prostaglandin E2 (PGE2) was still elevated or further increased, after chronic LPS exposure, as revealed by real time PCR and ELISA techniques. Acutely activated microglia, or their conditioned medium, reduced NPC survival, prevented neuronal differentiation and strongly increased glial differentiation, likely through the release of proinflammatory cytokines, whereas chronically activated microglia were permissive to neuronal differentiation and cell survival, and still supported glial differentiation. Our data suggest that, in a chronically altered environment, persistently activated microglia can display protective functions that favor rather than hinder brain repair processes. © 2008 Wiley‐Liss, Inc.
Factors affecting rainfall interception determined by a forest simulator and numerical model
Authors: Toba T. , Ohta T. 
Published: January 2008

AbstractTo elucidate the factors involved in interception loss, we conducted experiments in which we measured environmental variables such as rainfall intensity, forest structure, and weather conditions. An artificial forest consisting of 24 vinyl trees was used to examine the influences of forest structure and rainfall conditions on interception loss. The interception rate was higher at higher plant area index (PAI) values and wind speeds and lower with greater rainfall intensity.We confirmed the factors affecting interception loss by using an interception model based on the tank model. The artificial forest simulations provide new evidence that interception loss is influenced by the PAI, rainfall intensity, saturation deficit, and wind speed. The effect of the saturation deficit on the interception rate was unclear from the experimental results, but the single‐tank model revealed that wind speed strongly influences the effects of the saturation deficit on interception loss. Thus, whereas interception loss was not significantly affected by the saturation deficit at low wind speeds, it increased significantly with the saturation deficit under windy conditions. The model simulation also showed the sensitivity of each factor with regard to the interception rate. The sensitivity of rainfall intensity decreased as the PAI increased, and the sensitivity of the saturation deficit increased as the wind speed increased.The experiments and model calculations clarified the main elements affecting interception loss and their sensitivities. Compared with previous studies on interception loss, this study revealed a positive relationship between the PAI and interception loss, a negative exponential relationship with rainfall intensity, and the effects of the saturation deficit on interception loss.

AbstractA soluble complement inhibitor factor H (FH) and its splice variant factor H‐like protein (FHL) have been recently discovered to play a major role in malignant cell escape from complement‐mediated cytotoxicity in lung‐, ovarian‐ and glia‐derived neoplasms. The role of FH in colon cancer has not yet been examined. Here, we studied immunocytochemically FH/FHL expression in tumor samples derived from 40 patients, with both primary colon adenocarcinoma and metastatic foci in the liver. FH/FHL immunoreactivity was present in stroma of both primary and metastatic tumors, in virtually all patients. The cellular immunoreactivity was observed infrequently. Importantly, when analyzed quantitatively, FH/FHL immunoreactivity was significantly increased in liver metastases when compared with the primary sites. In addition, we have analyzed FH and FHL expression in 5 colon cancer cell lines: SW480, SW620, HCT116, HT‐29 and Lovo. FH mRNA and FH secretion were observed in SW620 and HT‐29 cells, whereas FHL was produced only by HT‐29 cell‐line. By confocal and electron microscopy, FH immunoreactivity was associated with the plasma membrane and intracellular vesicular structures. Finally, we have analyzed the role of FH in the susceptibility of SW620 colon cancer cells to complement‐mediated damage. When FH function was blocked, using specific antibody, the cells became more susceptible to lysis. Taken together, our results suggest an important role of FH/FHL in colon cancer cells defense against complement‐mediated cytotoxicity, and in metastatic process. © 2008 Wiley‐Liss, Inc.

AbstractImmunoselection and tumor evasion constitutes one of the major obstacles in cancer immunotherapy. A potential solution to this problem is the development of polyvalent vaccines, and the identification of more tumor‐specific antigens is a prerequisite for the development of cancer vaccines. To identify novel tumor‐specific antigens, suppression subtractive hybridization (SSH) was performed to isolate genes differentially expressed in human hepatocellular cancer (HCC) tissues. PLAC1 (PLACenta‐specific 1) was one of the genes identified highly expressed in HCC tissues but not in paired noncancerous tissues. Further analyses revealed its expression in several other types of cancer tissues as well as tumor cell lines, but not in normal tissues except for placenta. Among HCC samples tested, 32% (22/69) showed PLAC1 mRNA expression while the protein was detected in 23.3% (7/30). A serological survey revealed that 3.8% (4/101) of HCC patients had anti‐PLAC1 antibody response, suggesting the immunogenicity of PLAC1 in HCC patients. PLAC1 represents a new class of tumor associated antigen with restricted expression in placenta and cancer tissues, that may serve as a target for cancer vaccination. © 2008 Wiley‐Liss, Inc.
