Stereoselective metabolism and toxicity of the herbicide fluroxypyr methylheptyl ester in rat hepatocytes
Authors: Xu Xinyuan , Jiang Jiazhen , Wang Xinru , Shen Zhigang , Li Ranhong , Zhou Zhiqiang
Published: September 2011

We investigated the stereoselective degradation kinetics and toxicity of fluroxypyr methylheptyl ester (FPMH) in rat hepatocytes using a chiral high‐performance liquid chromatographic method. The T1/2 of (−)‐FPMH was about two times longer than that of (+)‐FPMH after the rat hepatocytes were incubated with 10, 20, and 50 μM of rac‐FPMH. There was no chiral conversion or transformation during their incubation with the hepatocytes. Toxicity differences were observed among the two enantiomers of FPMH and fluroxypyr (FP) in their EC50 values in rat hepatocytes. Of all the tested compounds, FP was most toxic to the rat hepatocytes. The (−)‐FPMH enantiomer showed higher toxicity than the (+)‐FPMH, whereas the racemic mixture displayed intermediate toxicity. The data presented here are important for a more thorough understanding of this pesticide and should be useful for its full environmental assessment. Chirality, 2011. © 2011 Wiley‐Liss, Inc.
Intratumoral neutrophils and plasmacytoid dendritic cells indicate poor prognosis and are associated with pSTAT3 expression in AJCC stage I/II melanoma
Authors: Jensen Trine O. , Schmidt Henrik , Møller Holger J. , Donskov Frede , Høyer Morten , Sjoegren Pia , Christensen Ib J. , Steiniche Torben
Published: September 2011

BACKGROUND:

Tumor cell and host immune cell interaction plays a key role in carcinogenesis. Signal transducer and activator of transcription 3 (STAT3) is constitutively activated in cancer and believed to be an important mediator of tumor‐induced immunosuppression. This paper aims to describe the prognostic impact of neutrophil and dendritic cell infiltration in primary melanoma and the association of this infiltration with activated STAT3 (pSTAT3) in primary melanoma cells.

METHODS:

Formalin‐fixed, paraffin‐embedded primary melanomas from 186 stage‐I/II melanoma patients surgically resected from 1997 to 2000. Infiltrating neutrophils (CD66b), dendritic cells (CD123+ and DC‐LAMP+), T‐lymphocytes (CD8) and pSTAT3 melanoma cell expression were studied by immunohistochemistry and evaluated as present or absent. DC‐LAMP+ cell infiltration was evaluated as absent/few versus dense. Study endpoints: relapse‐free survival, melanoma‐specific, and overall survival.

RESULTS:

The median observation time was 12.2 years (range, 10.4‐14.2 years). Fifty‐one deaths were observed of which 38 (20%) were melanoma‐specific. In a multivariate Cox proportional hazards model including ulceration and melanoma thickness, neutrophil and CD123+ dendritic cell infiltration were independently associated with poor prognosis (CD66b: hazard ratio [HR] = 3.13; 95% confidence interval [CI], 1.43‐6.83; P = .004; CD123: HR = 2.45; 95% CI, 1.22‐4.92; P = .012). The association between melanoma cell pSTAT3 expression and immune infiltration (neutrophils and CD123+ cells) was strong. pSTAT3 expression, CD8 and DC‐LAMP infiltration were not independently associated with poor prognosis.

CONCLUSIONS:

Neutrophil infiltration and CD123+ dendritic cell infiltration in primary melanoma are independently associated with poor prognosis. Melanoma cell expression of pSTAT3 is strongly associated with the surrounding immune infiltrate. Cancer 2012;. © 2011 American Cancer Society.
Effects of correlated color temperature on spatial brightness perception
Authors: Ju Jiaqi , Chen Dahua , Lin Yandan
Published: September 2011

The relationship between lamp color characteristics and brightness perception is not well known. In this study, nine lighting environment with correlated color temperature (3000 K, 5000 K, and 8000 K) and illuminance (1000 lx, 300 lx, and 100 lx) were created. Both the side by side visual matching and spatial brightness scaling experiments are designed to verify the effects of correlated color temperature on spatial brightness perception. The results of the study show that lighting with high correlated color temperature will have stronger spatial brightness perception than lower ones. © 2011 Wiley Periodicals, Inc. Col Res Appl, 2011
Efficient signcryption in the standard model
Authors: Li Fagen , Zhang Mingwu , Takagi Tsuyoshi
Published: September 2011

Signcryption is a cryptographic primitive that fulfills both the functions of digital signature and public key encryption simultaneously, at a cost significantly lower than that required by the traditional signature‐then‐encryption approach. The performance advantage of signcryption over the signature‐then‐encryption method makes signcryption useful in many applications, such as electronic commerce, mobile communications, and smart cards. In this paper, we propose an efficient signcryption scheme in the standard model. We prove that our scheme satisfies the confidentiality and strong unforgeability. Compared with the Tan's scheme, our scheme has | G | + | p | (320) bits shorter ciphertext, 2 | p | − | G | (160) bits shorter private key, and | GT | + | G | (1184) bits shorter public key. In addition, in the Tan's scheme, a user must hold two public key/private key pairs at one time if it were both sender and receiver. Our scheme only needs a public key/private key pair, which is more practical for application. Copyright © 2011 John Wiley & Sons, Ltd.
Accelerating physics in large, continuous virtual environments
Authors: Tracy Daniel J. , Brown Sheldon
Published: September 2011

Large virtual environments with many interactive objects pose high processing overhead for physics simulation and require real‐time results. Most of these objects are not being interacted with at the same time, leaving many in physical equilibrium. Modern physics simulation software eliminates some work for the case of objects at rest, but these objects still pose overhead because of potential activation during processing, which can constitute the majority of running time for some environments. We present a physics software design that eliminates overhead associated with bodies at rest, reducing the remaining running time to be proportional to the number of objects being interacted with. Our design consists of specific broad phase collision detection, contact group generation, and object storage methods, as well as intermediate structures and interfacing methods within the physics pipeline. It can be combined with various narrow phase collision detection, constraint solving, and integration techniques, as well as methods of parallelism. We show that our system produces a running time independent of the number of objects at rest, and that our methods compare favorably with published methods and available physics software when simulating environments with many objects at rest.

A Review and Synthesis of Positive Emotion and Reward Disturbance in Bipolar Disorder
Authors: Gruber June
Published: September 2011

Although positive emotion research has begun to flourish, the extremes and potential costs of positive emotion remain understudied. This is an ideal clinical model for studying the ways in which positive emotions are disrupted in bipolar disorder. Bipolar disorder is characterized by extreme bouts of expansive and persistent positive feelings. This paper reviews recent experimental studies, selectively examining positive emotion, in individuals at risk for, and diagnosed with, bipolar disorder. As an extension of this body of work, I present an account of positive emotion disturbance in bipolar disorder, referred to as positive emotion persistence. Implications are discussed for the study of bipolar disorder and positive emotion that follow. Copyright © 2011 John Wiley & Sons, Ltd.

A review of routing strategies for optical burst switched networks
Authors: Yahaya C. , Abd Latiff M. S. , Mohamed A. B.
Published: September 2011

The exact contribution of this paper is a review of existing state‐of‐the‐art routing strategies for optical burst switched networks developed by researchers to deal with burst contention before it happens. Routing schemes are implemented in space domain, which make them simple and cost effective. Additionally, the paper points out the importance of routing as an effective way to deal with burst contention compared to other solutions. It also underlines the main differences between contention avoidance schemes and contention resolution techniques for optical burst switched networks. We believe that this review will help different optical burst switched researchers involved in the development of route optimization algorithms to control burst contention.

Reaction of C(PPh3)2 with MI2 Compounds (M = Zn, Cd) – Formation and Crystal Structures of [I2Zn{C(PPh3)2}], [(I2Cd{C(PPh3)2})2] and the Salt‐Like Compounds (HC{PPh3}2)[MI3(THF)] and (HC{PPh3}2)2[ZnI4]
Authors: Petz Wolfgang , Neumüller Bernhard
Published: September 2011

The reaction of the carbodiphosphorane C(PPh3)2 (1) with group 12 MI2 compounds in THF leads to the salts (HC{PPh3}2)[MI3(THF)] (M = Zn2+, 2; Cd2+, 3) in good yields upon proton abstraction from the solvent. The salt‐like complex (HC{PPh3}2)2[ZnI4] (4) formed upon reaction of ZnI2 with 1 in toluene and subsequent heating of the resulting powder in 2‐bromofluorobenzene. When this reaction was carried out in 2‐bromofluorobenzene as the solvent, no proton transfer occurred, and the colorless addition compounds [I2Zn←1] (5) and [I2Cd←1]2 (6) were isolated. Compound 5 is monomeric, whereas in 6 the monomeric units are linked by bridging iodine ligands to produce a dimer. All compounds were characterized by X‐ray analyses and 31P NMR and IR spectroscopy.
Air Gap Microcell for Scanning Electrochemical Microscopic Imaging of Carbon Dioxide Output. Model Calculation and Gas Phase SECM Measurements for Estimation of Carbon Dioxide Producing Activity of Microbial Sources
Authors: Kiss András , Kiss Laszló , Kovács Barna , Nagy Géza
Published: September 2011

Most of SECM studies have been carried out in liquid or gel phases. A Severinghaus type, CO2 detecting potentiometric tip has been fabricated and used in gas phase SECM studies. The microcell tip is made without gas permeable membrane. Faster response, needed in SECM, was achieved by substituting the membrane with an air gap. The carbon dioxide concentration profile in the gas phase over a disc‐shaped colony of yeast has been detected with the new tip. Estimation of the carbon dioxide output of the fungi colony was attempted by fitting simulated curves to measured ones obtained with one dimensional (line) scans.
