New Rochelle, NY, December 18, 2014--Internet addiction is an impulse-control problem marked by an inability to inhibit Internet use, which can adversely affect a person's life, including their health and interpersonal relationships. The prevalence of Internet addiction varies among regions around the world, as shown by data from more than 89,000 individuals in 31 countries analyzed for a study published in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Cyberpsychology, Behavior, and Social Networking website until January 18, 2015.

In the article "Internet Addiction Prevalence and Quality of (Real) Life: A Meta-Analysis of 31 Nations Across Seven World Regions," Cecelia Cheng and Angel Yee-lam Li, The University of Hong Kong, present 164 Internet addiction prevalence figures, with an overall global prevalence estimate of 6.0%. Prevalence ranged from a low of 2.6% in Northern and Western Europe to a high of 10.9% in the Middle East. The authors describe factors associated with higher Internet addiction prevalence and how it relates to individuals' quality of life.

"This study provides initial support for the inverse relationship between quality of life and Internet Addiction (IA). It, however, finds no support for the hypothesis that high Internet accessibility (such as the high penetration rates in northern and western Europe), promote IA," says Editor-in-Chief Brenda K. Wiederhold, PhD, MBA, BCB, BCN, Interactive Media Institute, San Diego, California and Virtual Reality Medical Institute, Brussels, Belgium.

New Rochelle, NY, December 18, 2014--Pretreatment of cellulosic biomass using cell wall degrading enzymes is a critical step in the release of sugars needed to produce biofuels and renewable, biobased chemicals and materials. A new study that demonstrates and quantifies the impact of enzymatic hydrolysis and drying on the nanostructure and available reaction volume of pretreated hardwoods and switchgrass is published in Industrial Biotechnology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available on the Industrial Biotechnology website until January 18, 2015.

In the article "Cellulases Significantly Alter the Nano-Scale Reaction Space for Pretreated Lignocellulosic Biomass," Dong Yang, Jean-Yves Parlange, and Larry P. Walker Cornell University, Ithaca, NY, measured sugar yield and the accessible reaction space, or pore volume, of mixed hardwoods and switchgrass biomass treated with a mixture of cell wall degrading enzymes. Enzymatic pretreatment resulted in a substantial reduction in pore volume for both types of biomass. Drying of pretreated, enzymatically hydrolyzed biomass led to a decrease in accessible pore volume of as much as 80%, suggesting irreversible pore collapse.

In many respects, the work results in this paper, and in other recent publications, reflect the belief that physical/structural features of biomass are extremely important in defining the rate and extent of hydrolysis.

"One of the key steps in lignocellulosic hydrolysis is speeding up the rate and the extent of the hydrolysis reaction," says Co-Editor-in-Chief Glenn Nedwin, PhD, MoT, CEO and President, Taxon Biosciences. "Access to an understanding of the physical and structural features of biomass are critically important. This paper by Yang et al., offers new insights into this bioconversion process."

New Rochelle, NY, December 17, 2014-The Sunni Islamist terror organization known as the Islamic State, or ISIS, uses extreme violence and brutality against anyone it perceives as a threat to its goal of expansion and restoration of an Islamic Caliphate. The significant behavioral aspects of this unparalleled violence and its implications for the future are explored in a compelling Review article published in Violence and Gender, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Violence and Gender website at http://online.liebertpub.com/doi/full/10.1089/vio.2014.0037 until January 17, 2015.

In the article "The Violence of the Islamic State of Syria (ISIS): A Behavioral Perspective", coauthors Thomas Neer and Mary Ellen O'Toole, PhD, both retired FBI Agents, describe the growth of ISIS, its membership, and how gratuitous violence has become the organization's "brand." Other topics discussed in their article include violence and psychopathy, personality traits, use of propaganda, ISIS recruitment methods of young men and women, and strategies to counter ISIS.

These authors bring a unique and important perspective to understanding ISIS - a behavioral perspective. Both Mr. Neer and Dr. O'Toole worked for years as Profilers in the FBI's elite Behavioral Analysis Unit (BAU) where they analyzed violent offenders and their crimes. Mr. Neer's perspectives are also based on operational assignments throughout the world where he conducted behavioral and risk assessments of known and suspected terrorists. Dr. O'Toole lends her expertise in psychopathy and psychopathic behaviors of individuals and groups to ISIS leadership.

"ISIS is a global concern on many levels, and its grandiose display of extreme and ruthless violence is stunning," says Violence and Gender Editor-in-Chief Dr. O'Toole. "In this article, my colleague and I provide a behavioral assessment of this dangerous and evolving group comprised largely of young men in a vulnerable age group - late teens and twenties. I am sure you will find this unique and timely perspective both fascinating and enlightening, and extremely relevant for policy development."

New Rochelle, NY, December 17, 2014--Recognized for her pioneering work to develop gene therapy for hemophilia spanning several decades, taking it from the laboratory into human clinical trials, is Katherine A. High, MD, Spark Therapeutics. Also recognized for their demonstration of successful clinical applications of adeno-associated virus (AAV) vector-based gene therapy for hemophilia B are Amit C. Nathwani, MD, PhD, UCL Cancer Institute, and Arthur W. Nienhuis, MD and Andrew M. Davidoff, MD, St. Jude Children's Research Hospital. Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers, is commemorating its 25th anniversary by bestowing this honor on the leading pioneers in the field of cell and gene therapy selected by a blue ribbon panel* and by publishing a Pioneer Perspective by the award recipients. The Perspectives by Dr. High and Drs. Nathwani, Nienhuis, and Davidoff are available free on the Human Gene Therapy website at http://www.liebertpub.com/hgt.

In the Perspective entitled "Gene Therapy for Hemophilia: The Clot Thickens", Dr. High recounts why hemophilia was an attractive early target for gene therapy research and describes the genetic and physiological basis of the disease. She reviews early efforts using gene-based therapy to treat hemophilia B and provides a detailed account of her group's approach using an adeno-associated viral (AAV) vector to deliver the Factor IX gene, which encodes the clotting factor missing in patients with hemophilia B. Dr. High recalls the reasons for selecting skeletal muscle as the injection site for drug delivery, and she describes the limitations and unexpected obstacles that arose, such as patients' immune responses to the AAV vector and evidence of vector genetic material in the semen of the male patients, creating the risk of germline transmission.

In "Our Journey to Successful Gene Therapy for Hemophilia B", Drs. Nathwani, Nienhuis, and Davidoff present a detailed overview of their many years of collaborative research that has included a comparison of the safety and efficacy of different gene therapy delivery sites. The researchers also developed a sensitive assay system to enable detection of low levels of Factor IX and demonstrated stable therapeutic expression of the clotting factor. Over the years, they experimented with AAV vector types to achieve higher gene transfer levels and enable a therapeutic effect using lower and potentially safer doses. They describe the current status of their clinical research program and their early efforts in the development of gene therapy for hemophilia A.

"Hemophilia B has served as the model by which in vivo gene therapies have been evaluated," says James M. Wilson, MD, PhD, Editor-in-Chief of Human Gene Therapy, and Director of the Gene Therapy Program, Department of Pathology and Laboratory Medicine, University of Pennsylvania Perelman School of Medicine, Philadelphia. "Kathy was there from the beginning and has contributed to every major advance in hemophilia B gene therapy. Art, Andy, and Amit came together as a team soon after the turn of the century to eventually launch a clinical trial with a second generation AAV vector that served as a true milestone in the field of gene therapy. These pioneers are well-deserving of this recognition for their tenacity and courage to stay the course."

*The blue ribbon panel of leaders in cell and gene therapy, led by Chair Mary Collins, PhD, MRC Centre for Medical Molecular Virology, University College London selected the Pioneer Award recipients. The Award Selection Committee selected scientists that had devoted much of their careers to cell and gene therapy research and had made a seminal contribution to the field--defined as a basic science or clinical advance that greatly influenced progress in translational research.

New Rochelle, NY, December 16, 2014--Veterans of the U.S. armed forces who have received a diagnosis consistent with transgender status are more likely to have serious suicidal thoughts and plans and to attempt suicide. A new study shows that this group has a higher risk of suicide death than the general population of veterans, as described in an article in LGBT Health, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the LGBT Health website until January 16, 2015.

Based on data gathered from the VA National Patient Care Database from 2000-2009, John Blosnich, PhD, MPH and coauthors from VA Pittsburgh Healthcare System and University of Pittsburgh (PA), University of Rochester (NY), VA Central Office (Washington, DC), East Tennessee State University (Johnson City, TN), and VISN2 Center of Excellence for Suicide Prevention (Canandaigua, NY), determined that while the suicide death rate among veterans with transgender-related diagnoses was higher than for veterans in general, it was similar to the suicide death rate for veterans with serious mental illness such as depression or schizophrenia.

The authors report their findings in the article "Mortality among Veterans with Transgender-Related Diagnoses in the Veterans Health Administration, FY2000-2009."

"Although this study suggests comparably elevated rates of suicide among veterans with transgender-related ICD-9-CM diagnoses and veterans with any psychiatric diagnosis, suicides among transgender veterans occurred at a younger age, resulting in greater potential years of life lost," says LGBT Health Editor-in-Chief William Byne, MD, PhD, James J. Peters VA Medical Center, Bronx, NY and Icahn School of Medicine at Mount Sinai, New York, NY. "VA has a multifaceted strategy to reduce suicide among veterans. Its commitment in 2011, and reaffirmed in 2013, to provide respectful transgender-specific healthcare as well staff training in transgender cultural awareness and sensitivity may also address the high suicide rate among transgender veterans."

New Rochelle, NY, December 16, 2014-Consuming caffeinated or sugary drinks can affect the body's metabolism, causing changes in heart and respiratory rate and weight gain. The results of a new study exploring whether individuals respond differently to caffeinated drinks that do or do not contain sugar and to sugar alone are published in Journal of Caffeine Research: The International Multidisciplinary Journal of Caffeine Science, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free on the Journal of Caffeine Research website at http://online.liebertpub.com/doi/full/10.1089/jcr.2014.0023 until January 16, 2015.

The article entitled "Caffeine With and Without Sugar: Individual Differences in Physiological Responses During Rest", by Elaine Rush, PhD and coauthors, Auckland University of Technology (Auckland, New Zealand), describes a study in which heart rate and carbon dioxide production (as a measure of respiration) were measured 30 minutes before and after individuals consumed a defined quantity of sugar, caffeine, or sugar and caffeine. Responses to the different treatments varied widely among individuals.

"Given the caveat that sugar itself affects brain reward just as caffeine does, and this effect will in itself cause variations, this is still an essential paper for the scientist and the lay person to read," says Patricia A. Broderick, PhD, Editor-in-Chief of Journal of Caffeine Research, Medical Professor in Physiology, Pharmacology & Neuroscience, The Sophie Davis School of Biomedical Education, The City College of New York, The City University of New York, and Adjunct Professor in Neurology, New York University Langone Medical Center and Comprehensive Epilepsy Center.

Gang Bao will bring a host of new expertise to Rice Universitys part in the fight against cancer and many other diseases when he joins the faculty March 1.

The highly regarded Robert A. Milton Chair in Biomedical Engineering at Georgia Institute of Technology and Emory University is the latest recruit to move to Houston with $6 million in funding from the Cancer Prevention and Research Institute of Texas (CPRIT).

Bao and his colleagues, nine of whom will join him at Rice, cover a wide range of research linked primarily by their interest in the genetic roots of disease and the promise of nanotechnology and biomolecular approaches to treat them.

Among their ongoing projects, lab members are working on targeted genome modification using engineered nucleases, the development of magnetic nanoparticles for use as contrast agents and for ablation of tumors and the application of fluorescent molecular beacons for specific RNA detection in living cells.

Dr. Bao has an outstanding track record of center leadership in developing and applying nanomedicine for disease diagnosis and treatment, and is a fantastic addition to the Rice effort in translational nanomedicine, said Michael Deem, chair of the Department of Bioengineering and the John W. Cox Professor of Biochemical and Genetic Engineering.

His work in the mid-2000s involved groundbreaking contributions to the molecular imaging field, and he has turned to nanomedicine and nanomaterials-based interventions, for example, with special contributions to the isolation of specific cell types from differentiating human pluripotent stem cells. Most recently, Dr. Bao has made major contributions to the use of the CRISPR/Cas9 system for genome editing, Deem said.

The opportunity to work at Rices BioScience Research Collaborative, with its close connections and proximity to the Texas Medical Center, made the offer too good to resist, said Bao, who will be the Foyt Family Professor in the Department of Bioengineering and the CPRIT Senior Scholar in Cancer Research at Rice.

One thing I really like is that this building is right in the Texas Medical Center, very close to (the University of Texas) MD Anderson (Cancer Center), Texas Childrens (Hospital) and Baylor (College of Medicine), he said. For cancer research, this will make it much easier for me to work with colleagues at MD Anderson, a few blocks away, or at Baylor.

Another attraction, really, is that the undergraduate programs at Rice are super strong. I always want to attract undergraduates to my lab to do research, he said.

Along with his lab, Bao brings his Nanomedicine Center for Nucleoprotein Machines to Rice. The National Institutes of Health-funded center is developing gene correction techniques to address an estimated 6,000 single-gene disorders. Their first target is sickle cell disease, caused by a single mutation in the beta-globin gene. The mutation causes the body to make sticky, crescent-shaped red blood cells that contain abnormal hemoglobin and can block blood flow in limbs and organs.
