A Novel Mutation In Arg1 Gene Is Responsible For Arginase Deficiency In An Asian Family., Jozef L. Hertecant, Lihadh I. Al-Gazali, Noushad S. Karuvantevida, Bassam R. Ali

Saudi Medical Journal

Argininemia is a rare autosomal recessive metabolic disorder caused by a deficiency in the arginase enzyme, which is the final enzyme in the urea cycle and responsible for the hydrolysis of arginine to urea and ornithine. The disease becomes symptomatic during childhood and is characterized by progressive spastic quadriplegia, progressive mental impairment, growth retardation, and periodic episodes of hyperammonemia. At least 19 distinct mutations in the ARG1 gene have been identified indicating the molecular heterogeneity of this condition. We report a homozygous novel mutation (c.93 delG) in the ARG1 gene from 3 affected children of a Pakistani family living in …

Expression Artifact With Retroviral Vectors Based On Pbmn, Yoshitaka Fukunaga, Robert A. Svoboda, Ronald Cerny, Keith R. Johnson, Margaret J. Wheelock Dec 2009

Expression Artifact With Retroviral Vectors Based On Pbmn, Yoshitaka Fukunaga, Robert A. Svoboda, Ronald Cerny, Keith R. Johnson, Margaret J. Wheelock

Ronald Cerny Publications

While characterizing various splice forms of p120 catenin, we observed what appeared to be a novel posttranslational modification of p120, resulting in a higher molecular weight form that was dependent on the splicing pattern. Further investigation revealed the higher molecular weight form to be a fusion protein between sequences encoded by the retroviral vector and p120. We found that the publicly available sequence of the vector we used does not agree with the experimental sequence. We caution other investigators to be aware of this potential artifact.

Responses To “Comment On ‘Response To Plevin: Implications For Life Cycle Emissions Regulations’” And “Assessing Corn Ethanol: Relevance And Responsibility”, Adam Liska, Kenneth Cassman Dec 2009

Responses To “Comment On ‘Response To Plevin: Implications For Life Cycle Emissions Regulations’” And “Assessing Corn Ethanol: Relevance And Responsibility”, Adam Liska, Kenneth Cassman

Adam Liska Papers

This letter responds to two issues concerning the greenhouse gas (GHG) emissions intensity of corn-ethanol that were raised in discussions of our response (Liska and Cassman 2009) to Plevin’s article (2009), which critiques our original research (Liska et al. 2009) published in the Journal of Industrial Ecology. ... The suggestion by Anex and Lifset (2009) that corn-ethanol does not reduce GHG emissions by 47% compared to gasoline, but instead by “somewhere between” 35 to 40%, is unsubstantiated.

Efficacy Of A Manualized And Workbook-Driven Individual Treatment For Social Anxiety Disorder, Deborah Roth Ledley, Richard G. Heimberg, Debra A. Hope, Sarah A. Hayes, Talia I. Zaider, Melanie Vandyke, Cynthia L. Turk, Cynthia Kraus, David M. Fresco

Department of Psychology: Faculty Publications

Social anxiety disorder is a prevalent and impairing disorder for which viable cognitive-behavioral therapies exist. However, these treatments have not been easily packaged for dissemination and may be underutilized as a result. The current study reports on the findings of a randomized controlled trial of a manualized and workbook-driven individual cognitive-behavioral treatment for social anxiety disorder (Hope, Heimberg, Juster, & Turk, 2000; Hope, Heimberg, & Turk, 2006). This treatment package was derived from an empirically supported group treatment for social anxiety disorder and intended for broad dissemination, but it has not previously been subjected to empirical examination on its own. …

Law's Expressive Value In Combating Cyber Gender Harassment, Danielle K. Citron Dec 2009

Law's Expressive Value In Combating Cyber Gender Harassment, Danielle K. Citron

Faculty Scholarship

The online harassment of women exemplifies twenty-first century behavior that profoundly harms women yet too often remains overlooked and even trivialized. This harassment includes rape threats, doctored photographs portraying women being strangled, postings of women’s home addresses alongside suggestions that they should be sexually assaulted and technological attacks that shut down blogs and websites. It impedes women’s full participation in online life, often driving them offline, and undermines their autonomy, identity, dignity, and well-being. But the public and law enforcement routinely marginalize women’s experience, deeming it harmless teasing that women should expect, and tolerate, given the Internet’s Wild West norms …

Rainsford Island Shoreline Evolution Study (Rises), Christopher V. Maio Dec 2009

Rainsford Island Shoreline Evolution Study (Rises), Christopher V. Maio

Graduate Masters Theses

RISES conducted a shoreline change study in order to accurately map, quantify, and predict trends in shoreline evolution on Rainsford Island occurring from 1890-2008. It employed geographic information systems (GIS) and analytical statistical techniques to identify coastal hazard zones vulnerable to coastal erosion, rising sea-levels, and storm surges. The 11-acre Rainsford Island, located in Boston Harbor, Massachusetts, consists of two eroded drumlins connected by a low-lying spit.

Cyber Influence, William Hutchinson Dec 2009

Cyber Influence, William Hutchinson

Australian Information Warfare and Security Conference

This paper explores influence in the cyber-world and the ability and effectiveness of influence campaigns in this medium. It examines the possibilities of influence in the online world as examines the potential of mobile technologies in this area. The contentious link between influence and behavioural change is investigated. Counterinfluence in the context of radicalisation is also looked at. Whilst it is inevitable that the digital medium is and will be used for influence campaigns and will be influential regardless if there are concerted ‘campaigns’ or not, it effects in terms of behavioural change are still open to question.

Culture Jamming: From Activism To Hactivism, Kay Hearn, Rachel J. Mahncke, Patricia A. Williams

Australian Information Warfare and Security Conference

A new kind of Internet threat has emerged. Hacking is increasingly being used as a weapon by individuals to promote their political ideologies by engaging in distributed citizen-based warfare. Their aim is to disrupt communications using internet enabled networks and organisations. Examples of these online assaults during 2009 were evident during the Iranian protests and the Melbourne International Film Festival. Such attacks use denial of service techniques and utilised social networking websites such as Facebook, Twitter and You Tube to post links to access hacking instructions. Posts on social networking websites and news stories from a variety of sources online, …
