George Tuszynski

Like many biomedical researchers, George Tuszynski would like to cure cancer. But in his quest, he may have stumbled across a solution to a humbler problem: wrinkled skin. Professor of Neuroscience in Temple’s School of Medicine and Professor of Biology in Temple’s College of Science and Technology.

Tuszynski and his group, along with In Kine Pharmaceutical Co., a small pharmaceutical company based in Blue Bell, PA, have developed three molecules that prevent tumor growth by inhibiting blood vessel formation, which is called angiogenesis. One of the molecules has been named angiocidin, while the other two are peptides.

Angiocidin, a tumor-inhibiting novel protein discovered by Temple University researchers, was revealed last year to have a therapeutic application in treating leukemia. The study, “The Novel Angiogenic Inhibitor, Angiocidin, Induces Differentiation of Monocytes to Macropahges,” published in 2008 in the journal Cancer Research. The research was done by Temple biology doctoral student Anita Gaurnier-Hausser under Tuszynski's direction.

What cancer has in common with aging skin is that in both conditions, cells have stopped growing properly. Stem cells, characterized by their ability to renew themselves through mitotic cell division and differentiating into a diverse range of specialized cell types, create healthy well-behaved cells. Tuszynski has shown that he "can repair damaged skin. Given the right stem cells, you can make the cells grow up and behave."

“Angiocidin is a protein that has a lot of anti-cancer activity and inhibits angiogenesis, a physiological process involving the growth of new blood vessels from pre-existing vessels, which is a fundamental step in the transition of tumors from a dormant state to a malignant state,” said Tuszynski, who discovered the protein.

Tuszynski said that over the years, the researchers had looked at the protein’s effect on solid tumors like breast cancer, prostate cancer and colon cancer. 

“All of these cancers are inhibited by Angiocidin by virtue of the fact that this protein inhibits vascularization or the formation of new vessels,” he said. “We decided we wanted to look to see if Angiocidin had any effect on hematologic malignancy, and we chose leukemia.”

Tuszynski said leukemia cells arise from monocytes, a specific white blood cell that is a part of the human body’s immune system that protects against bloodborne pathogens and moves quickly to sites of infection. As monocytes enter tissue, they undergo a series of changes to become macrophages.

When the researchers treated the leukemia cells, “our molecule was able to induce a differentiation of these monocytic leukemia cells into a normal, macrophage-like phenotype,” he said.

“This indicates perhaps a new therapeutic application for this protein, that it could differentiate hematologic malignancies into a normal-like state, allowing then for chemotherapy because normal cells are susceptible to chemotherapy treatment,” said Tuszynski, who is also a member of the Sol Sherry Thrombosis Research Center in Temple’s School of Medicine.

He added, however, that Angiocidin must remain present with the differentiated cells or they will revert back to their leukemia phenotype. “We haven’t repaired the genetic abnormality in the cell, but what we have done is push them into a more normal phenotype that could then be treated more easily.”

Tuszynski also said that the research demonstrates the ability of Angiocidin to stimulate the body’s immune system by differentiating monocytic cells into macrophages, which function to ingest bacteria and protein debris as part of the immune system.

“We did gene array analysis of the differentiated versus the undifferentiated cells and we discovered that there were many genes characteristic of immune cells that were up-regulated in the differentiated leukemia cells,” he said. “That Angiocidin can stimulate differentiation and stimulate the immune system is basically a new activity that we discovered with this protein that we had never really anticipated before.”

The research was funded by the National Institutes of Health and Temple University.

In 1987, our laboratory first showed that thrombospondin -1 (TSP-1), a platelet protein, functioned as a cell and platelet adhesive protein and that TSP-1 could promote metastasis formation in a murine model of experimental metastasis. Since then we have identified structural domains within the TSP-1 molecule and a new TSP-1 receptor that may mediate cell-cell and cell-substratum interactions operative during the metastatic cascade and the process of angiogenesis. We found that a number of peptides homologous to CSVTCG promoted the adhesion of a variety of normal and tumor cells and inhibited platelet aggregation and tumor cell metastasis, whereas control peptides had no effect. Our results further demonstrated that these peptides inhibited tumor lung metastases and angiogenesis presumably by competing with endogenous TSP-1 for TSP-1 tumor cell receptor sites. This conclusion was further supported by the observation that anti-CSTSCG antibody, which specifically recognized TSP-1, inhibited TSP-1-dependent cell adhesion, platelet aggregation, and tumor cell metastasis, whereas control IgG had no effect. These results suggest that CSVTCG and CSTSCG present in the type I repeat sequences of TSP-1 function in the adhesive interactions of TSP-1 that mediate platelet aggregation, angiogenesis and tumor cell metastasis. 

The TSP-1 receptor specific for the CSVTCG residues in the type 1 repeats of TSP-1 was isolated from lung carcinoma by CSVTCG-Sepharose chromatography. Anti-receptor IgG and inhibited lung carcinoma cell spreading and adhesion and platelet adhesion on TSP-1 but not on fibronectin and laminin. Anti-CSVTCG receptor antibody blocked breast cancer invasion in vitro and metastasis and tumor progression in an in vivo athymic model of breast cancer progression. These data as well as immunohistochemical studies showing that this receptor highly over-exepressed in breast carcinoma and its neovasculature as well as many other tumors, including lung, melanoma, ovarian, prostate, pancreatic, colon, gastric, and hepatocelluar carcinoma and that this receptor is predictive of poor patient outcome in squamous carcinoma of the head and neck strongly support the conclusion that both TSP-1 and its receptor mediate cancer progression. 

The receptor has recently been cloned and expressed as a soluble protein in bacteria. Recombinant protein, referred to as angiocidin, specifically inhibited endothelial adhesion, tube formation and viability, while having no effect on a variety of cells including fibroblasts, smooth muscle cells, and tumor cells. Angiocidin localized to the vasculature and inhibited Lewis Lung carcinoma and B16F10 melanoma growth in mice by more than 95%. Similarly, a monoclonal receptor antibody inhibited more than 50% tumor growth. Therefore, angiocidin may be new target for the development of an anti-angiogenic agent for the treatment of cancer. 

Based on these results, we believe that CSVTCG peptides and the CSVTCG specific TSP-1 receptor (angiocidin) are targets for the development of cancer therapeutics, angiogenesis inhibitors and imaging agents as well as anti-thrombotics. Preclinical studies are now underway in preparation for the use of angiocidin, anti-angiocidin antibodies and the CSVTCG peptides for the treatment of cancer in man. Finally our laboratory is searching for new molecules and new mechanisms that can be targeted for development of cancer therapeutics and diagnostics. In collaboration with Dr. Mahesh Sharma, we have identified annexin II as a potential receptor mediating angiogenesis and tumor progression. We have developed a monoclonal annexin II antibody that reduces tumor growth by more than 50%. This antibody may also find utility as a diagnostic tool for the detection of annexin II in sera and solid tumors.

Learning and addiction are inked in the brain in unexpected ways, according to Thomas J. Gould, a professor of pharmacology at Temple University. The well-documented learning-related changes in the strength of neuronal connections in the brain not only underlie memory formation and storage but are also affected by drugs of abuse, such as nicotine or alcohol. The goal of Gould's research is to use genetic, pharmacological, behavioral, molecular and electrophysiological techniques to study the effects of these drugs on the neurobiology of learning and memory.  

In 1988, the US Surgeon General concluded that tobacco products are addictive and that nicotine is the main pharmacological agent in tobacco responsible for tobacco's addictive nature.  Many questions remain, however, about nicotine.  It is not completely understood what nicotine's effects on neurological/behavioral function are nor is it understood why nicotine is addictive.  One reason for the incomplete understanding of nicotine addiction may be that addiction is a complex disorder with many factors contributing to the disease.  The symptoms of nicotine withdrawal, which can include physical symptoms, impairments in cognition, and mood dysfunction may be a critical factor in the high relapse rates that occur in cigarette smokers.  Furthermore, genetic factors may modulate the acute, chronic, and withdrawal effects of nicotine on cognition.  Although animal models have provided useful insight into the somatic and affective symptoms of nicotine withdrawal, little animal research has focused on the effects of nicotine withdrawal on learning. 

 Research from Gould's lab uses contextual fear conditioning, a hippocampus-dependent form of classical conditioning, as an animal model for the effects of nicotine on cognition. The goals of the research are: to investigate the effects of nicotine on learning, to identify the cellular and molecular mechanisms that are altered by nicotine use, and to identify genetic factors that may contribute to nicotine-associated neurobehavioral effects.  Our laboratory uses behavioral, pharmacological, genetic, molecular, and electrophysiological approaches to address these questions. 

Nicotine addiction is a disorder that may be maintained by many factors, including nicotine withdrawal-associated deficits in cognitive processes.  One goal of our laboratory is to test pharmacological agents that can potentially reduce nicotine withdrawal-associated deficits in cognition.  Previous research has established that the noradrenergic system is involved in both learning and attention, and recent studies from our lab have demonstrated that nicotine withdrawal-associated deficits in contextual fear conditioning can be reversed by both nicotine replacement and by norepinephrine reuptake inhibitors.  By identifying cellular and molecular processes that can ameliorate the effects of nicotine, more effective smoking cessation strategies can be developed.

The Effects of Alcohol and Nicotine On Cognition 

Alcohol is frequently referred to as a "gateway" substance to nicotine use and abuse, and research has demonstrated that nicotine use in adolescents can predict a transition from social to problem drinking.  However, the reasons for why these two drugs are co-abused remain unclear, although several factors are likely to be involved.  One possible explanation for the co-abuse of nicotine and alcohol is that nicotine may reduce some of the negative symptoms of alcohol, such as disrupted cognition.  Evidence in favor of this explanation comes from studies that have shown that alcohol impairs learning in hippocampus-dependent and independent procedures, while nicotine can reverse these deficits.  An additional goal of our laboratory is to examine the neural substrates underlying the interactive effects of alcohol and nicotine on learning, and also to understand the effects of alcohol on learning when administered alone.  Understanding the interactive effects of these drugs on cognition will aid in developing more effective treatments for both alcoholism and nicotine addiction.

Ellen Walker

Clearing the fog; 

Researcher gets $1.5 million dollar grant to examine side effect of chemotherapy 

Many of the side effects from chemotherapy are well documented: Fatigue, nausea and hair and weight loss. But there is another one that has split the medical community about whether is even exists. It's called chemotherapy-induced cognitive deficits or “chemo fog” and pharmacologist Ellen Walker hopes her research not only proves its real, but finds the cause. 

Walker, a PhD and associate professor of pharmacodynamics at the School of Pharmacy, received a $1.5 million dollar National Institutes of Health grant at the beginning of this year to study the possible effects of drugs used during chemotherapy on cognitive impairment. It’s a big grant, with perhaps even bigåger implications for how researchers and patients deal with chemotherapy-induced cognitive deficits, which chemotherapy patients liken to being in a fog, as if they’re brain isn’t working right. Misplaced items, inability to multi-task, short-term memory loss are hallmarks of the condition. And while there is clinical evidence to support its existence, research studies on the topic are scant. 

“My colleague Bob Raffa and I were stunned at the lack of published literature, considering cancer patients have been getting chemotherapy for nearly 50 years,” said Walker. “Most studies have looked at how well chemotherapeutic agents kill the tumor, not if they cause a cognitive deficiency, like memory loss.” 

Walker and Raffa decided to fill that void. Two years ago, Walker and PharmD student John Foley, set out to see if certain chemotherapeutic agents caused memory and learning deficits in mice. They tested two older drugs commonly used to treat breast cancer, a cancer with recently higher survival rates whose survivors have dominated the limited clinical research on chemotherapy-induced cognitive deficits. They suspected the drugs, methotrexate and 5-fluorouracil, weren’t toxic alone, but when given together, could cause deficits. Six months into their research, their hunch proved right. 

“Alone, methotrexate didn’t cause learning or recall deficits in mice when given once. Mice given 5-flurouracil once showed some deficits in recall, but when we gave the mice both drugs, it had a synergistically worse effect on their ability to learn and remember.” 

In other words, the mice forgot what they learned a day after being given the chemotherapeutic agents. And as Walker expanded their research, giving the drugs once a week for three weeks, they saw even more deficits than just giving it acutely. Armed with their results, this one-time side project became a priority. What followed were months of research and the involvement of more colleagues to help define better dose combinations and regimens. But there was also the ping-pong of NIH reviews and revisions to endure and Walker and her research team had run out of money. In March, 2008, a $50,000 bridge grant through the Office of Research and Strategic Initiatives allowed her research to continue. 

Eight months later, the NIH sent word that they were not only funding Walker’s research with a five year, $1.5 million dollar grant, but she received a priority percentile ranking of 0.8, placing it at or very near the top of all peer applications. 

“I had to look at the score twice because I couldn’t believe it,” said Walker. 

It wasn’t just Walker who was impressed by the score. 

“I was delighted to learn about the grant and its truly outstanding ranking,” said Larry F. Lemanski, Ph.D., Senior Vice President for Research and Strategic Initiatives at Temple.  “This major grant from the National Institutes of Health will allow Dr. Walker to significantly expand her research programs. At the same time, the award will increase Temple’s reputation as a major player in this very important field of biomedical research.” 

Indeed the funding will allow Walker to triple her efforts. She can put someone full-time on the project and study four more chemotherapeutic agents. And down the road, she would like to figure out how to protect the brain before chemotherapy to prevent chemo fog. 

For now, there is still controversy surrounding chemo fog, as clinicians and scientists debate if the disease itself or the drugs to fight cancer cause it. Other culprits could include genetics, hormone inhibitors, anemia and early-onset menopause. Instead of a natural onset, chemotherapy often catapults women into menopause, potentially leaving them fuzzy-minded. And there are those who doubt chemo fog is real. Walker believes it is. She recalls how during her mother’s battle with breast cancer, she put a chicken still covered in plastic wrapping in the oven for dinner. 

“It seemed like she wasn’t always thinking clearly even after her chemotherapy was over. I always wondered was it the psychological stress of cancer, the chemotherapy, or some other side effect of the many medications she received.” 

Ellen Walker may well be on her way to finding the answer. 

Jennifer Cromley

Jennifer Cromley, assistant professor of educational
psychology in the College of Education, is developing and
testing new instructional techniques aimed at teaching
high-school science students how to use the diagrams that
appear in their biology textbooks.

Research from a range of disciplines has shown that people
have difficulty making sense of diagrams. The investigators
had previously found that inference and other high-level
processes that are important for learning from text are even
more important for learning from diagrams. They further showed
that students who use textbook diagrams the least show the
smallest gains in content understanding from the textbook.

The investigators will capitalize on commonalities among
several theories of diagrammatic reasoning to develop four
interventions, following an additive design, aimed at
improving classroom instruction in how to use diagrams. In
each iteration, one additional intervention feature is added
to the initial intervention.

In the first intervention, they will teach the components of
diagrams (i.e., how to read captions, color keys, and other
conventions of diagrams). In the second, they will also teach
the coordinating of text and diagrams. In the third, they will
also have the students engage in self-explanation. In the
fourth, they will also have students construct their own
drawings.

In conjunction with these experimental studies, the
investigators will collect eye tracking data on a subset of
participants pre- and post-intervention in order to look for
possible changes in gaze patterns.

Joanna Maselko

Joanna Maselko (Public Health), a social and psychiatric epidemiologist who researches the socioeconomic determinants of mental health in the global context, and the relationship between religious engagement/spirituality and health, recently received a grant from the John Templeton Foundation for the project, “Stress, Violence and Spiritual Capital" and a grant from the National Institutes of Health. Maselko has done interesting work on the relationship between religious belief and mental health. There seems to be some kind of correlation between belief and sanity, but Maselko is quick to point out that one can't infer a causal relationship. A factor in her work is that it is meta-research: she is not gathering new data, but rather using longitudinal data, of which the collection began 40 years ago, and for a very different purpose. Hers is the first longitudinal study of religion and mental health. Some of work centers on the sociological concept of "social capital" and its relation to mental health. This work is funded by the Templeton Foundation, which she reports makes her work somewhat suspect to some scientists. She feels that this source of funding is accepted without prejudice at Temple; this open-mindedness is one reason that she came to Temple, when she might have gone to a school that has a college of public health.



Currently, Dr. Maselko is conducting research on the social determinants of mental health in international settings. Of particular interest is the link between economic development and mental health in developing countries, especially in South Asia. Economic development is often associated with changes that impact family and social networks and supports, which might have adverse effects on mental health. On the other hand, increased economic opportunities are associated with improved health and well-being and Dr. Maselko hopes to elucidate the aspects of economic and social development that are salient to health. She has conducted research on women’s empowerment in Bangladesh, socioeconomic disadvantage and suicide in Goa, India, and is currently conducting a study exploring the connections between negative life events, debt, spiritual coping and mental health in Karnataka, India.



Dr. Maselko also conducts studies on the role of individual’s changing levels of religious engagement over the lifecourse in the development of psychopathology. She is especially interested in how gender and socioeconomic status impacts the relationship between religious engagement/spirituality and health, with a special focus on diverse religious environments. For example, findings from this line of research suggest that denominational differences in the strength of the association between religious engagement and psychological health between men and women. Ongoing projects explore the role of religious institutions in shaping the religion-health connection.



Women who stop being religiously active are three times more likely to suffer generalized anxiety disorder than women who have always been religiously active, researchers report.



"One's lifetime pattern of religious service attendance can be related to psychiatric illness," she said. Maselko and her team analyzed data from 718 adults who shared details of their religious activity in youth and adulthood. They found that a majority of the respondents changed their level of religious activity between childhood and adulthood. The data is published in the January issue of Social Psychiatry and Psychiatric Epidemiology.



According to Maselko, the gender differences in the relationship between religious participation and mental health may be tied to social networks. Women are more likely to build them through their religious activities, and then to feel the loss of those networks when they stop attending church, she explained.



Slightly more than one-third of the women reported always being religiously active. Half said they had not been active since childhood. About 7 percent of the women who were always religiously active could be categorized as having generalized anxiety disorder, compared with 21 percent of those who had ended their religious activities.



People with generalized anxiety disorder experience worries and concerns out of proportion to their daily lives, according to the National Institute of Mental Health. The disorder is diagnosed if the worries do not abate after six months. About 6.8 million Americans suffer from the disorder, which can seriously interfere with sleep and relaxation. Women are two times more likely to suffer from anxiety disorder than men.



"Everyone has some spirituality, whether it is an active part of their life or not; whether they are agnostic or atheist or just 'non-practicing.' These choices potentially have health implications, similar to the way that one's social networks do," Maselko said.

Susan Varnum, professor of chemistry in the College of Science and Technology, is conducting important research into the role that inflammation, the complex biological response of tissues to such harmful stimuli as pathogens or irritants, plays in the human body. Inflammation is a good thing, a protective attempt by the organism to remove the injurious stimuli and start healing.  In the absence of inflammation, wounds and infections would never heal and progressive destruction of the tissue would set in. But chronic inflammation can have unexpected and undesirable consequences. Inflammation is normally tightly regulated by the body, because running unchecked it can lead to such diseases as hay fever, atherosclerosis, and rheumatoid arthritis. 

Varnum and her colleagues are investigating many such potential problems and also creating better ways to measure the severity of inflammation. One quantitative measure of how inflamed a tissue is can be the presence of certain fatty acids that accompany inflammation. Varnum's research suggests that these lipids may play a role in the development of the free radicals that lead to disease.

The are evaluating lipid biomarkers of inflammation to see what cardiovascular risks it suggests. The purpose of this research is to understand how gender differences are manifested in cardiac vascular risk. More specifically, they ask, are the current clinical risk assessment tools sufficient for therapeutic recommendations? The hypothesis is that the state of inflammation in cardiac tissues from a variety of metabolic factors and disease provides a reliable risk assessment tool. Therefore, analytical tools to quantitatively assess the levels of inflammation will be developed; and these methods will be applied to understanding the development of cardiovascular disease and related gender differences using a rat model.

They are looking at inflammation in tumor progression. They are interested in the molecular mechanisms that regulate tumor progression in colon cancer. Currently they are developing bioanalytical methods to quantify major eicosanoids that regulate inflammation and tumor growth.

They are profiling the course of hypertensive disease. Determination of creatinine and 8-iso PGF2 from the same urine sample is efficient. Levels of urinary isoprostane and creatinine are markers of disease progression as is age. In this study, levels of inflammatory biolipids are quantified and correlated with levels of natural sex hormone to profile progression of disease from hypertensive conditions.

They also are interested in understanding how resolution of inflammation encourages recovery from traumatic brain injury and how the availability of brain active biolipids affects brain function.

Temple University, Ben Franklin Technology Partners and Department of Community and Economic Development Establish Pennsylvania Environmental Center for Pharmaceutical Industry with $1.6 Million Feb. 9

The new Center for Pennsylvania Environmental Technologies for the Pharmaceutical Industry (PETPI) will offer technological support to the the pharmaceutical industry in the Delaware Valley--and make Temple University a worldwide hub for research and development dealing with the green manufacture of medicines.. 

The Temple University Office of Research and Strategic Initiatives honored Rominder Suri, the founder of the center and an associate professor of civil and environmental engineering at the Temple College of Engineering, with a reception marking the establishment of the center on Monday, Feb. 9.

Rebecca O. Bagley, the deputy secretary of technology investment for the Pennsylvania  Department of Community and Economic Development (DCED), presented a check for $1.6 million to Suri and Larry Lemanski, the senior vice president for research and strategic initiatives at Temple.

“Temple has really invested in getting outstanding people who can translate basic research into useful applications,” Lemanski said. "The Commonwealth is matching that commitment with this grant." The Center for Pennsylvania Environmental Technologies for the Pharmaceutical Industry will establish a source for the technology and expertise that will help pharmaceutical companies and businesses that work with them minimize their effect on the environment.

The center, Suri says, "will be developing cost and energy efficient technologies with a goal of having an economic impact--both on new and existing companies. The vision is to create a technology hub, of global prominence, in the region to make Pennsylvania more attractive to the pharmaceutical, engineering design and equipment manufacturing industries." Research will be conducted in state-of-the-art labs to develop new technologies and processes for pharmaceutical waste management, create business opportunities for engineering design firms and equipment vendors, create employment opportunities, develop a high tech work force, and advance environmental stewardship.

"We will bring all the latest research here, provide the expert knowledge needed for research and development, and then export the technology--not just in the Delaware Valley, but all over the world," Suri says. "Due to the high energy costs there is a lot of industry interest in energy efficient waste treatment technologies. Equipment manufacturers have a need to optimize their equipment for lower energy consumption, in order to to compete in the global market. By implementing high energy efficiency technologies, the pharmaceutical  industry can minimize the impact of waste management on the cost of goods sold."

A researcher whose interests include emerging contaminants, sustainable technologies, and reactor engineering and process design, Suri received his Ph.D. degree in environmental engineering from Michigan Technical University in 1995. He was previously a professor in the department of civil and environmental engineering at Villanova University where he directed the Center for the Environment.

“Ben Franklin partnered with Temple University to support this important initiative because it has the potential to impact so many aspects of our lives, " said RoseAnn B. Rosenthal,president of BFTP. "PETPI is a pharmaceutical technology hub of global prominence in the region. It affirmatively partners with the pharmaceutical industry, which is so important to our region, to insure that drug development and environmental protection are compatible objectives. It’s efforts will interact with, attract and create pharmaceutical companies and high technology jobs for the region.”

The grant from DCED also assisted Suri in winning a National Science Foundation (NSF) grant to establish a national Center at Temple on Water and Environmental Technology (WET). This NSF WET Center is between Temple University, University of Arizona and Arizona State University, with Temple as the Lead university. Dr Suri will direct this newly formed NSF center. The goal of this Center is to perform environmental research and development for industry including the Department of Defense, and to promote the national water quality.

Ben Franklin Technology Partners (BFTP) of SE PA assisted Temple in the development of PETPI’s proposal to DCED. Representatives of each industry sector and Ben Franklin will serve on PETPI’s Advisory Board, which will direct general policies and procedures.

BFTP will assist the center in technology commercialization. The technologies developed in the center will lead to creation of new companies in Pennsylvania, development of high tech work worce, and creation and retention of new jobs in the Commonwealth. The center will offer an Environmental Network of Excellence for Pharma and related Industries such as equipment manufacturers and engineering design firms, according to Suri. The grant from DCED also assisted Suri in winning a National Science Foundation (NSF) grant to establish a national Center at Temple for water and environmental technology.

Temple research finds an ADHD drug could help individuals with ap

Temple research finds an ADHD drug could help individuals with aphasia regain language abilities.

When ABC journalist Bob Woodruff was injured while reporting in Iraq in 2006, he suffered severe head injuries that caused him to lose his ability to recall and produce common words — a condition called aphasia. Today, Woodruff has recovered most of his language skills thanks to intensive behavioral therapy — reading and repeating words and sounds.

“The standard of care for patients with aphasia has always been and will always be speech/language therapy, but a new area is opening up that looks at what drugs can be used in combination with therapy to enhance recovery from brain damage and help the brain repair itself,” said Gerry Stefanatos, D.Phil., an associate professor of communication sciences and disorders in the College of Health Professions. “We’re looking at the mechanism of how this combination works — it’s underlying effect on patients with aphasia.”

In research presented at the International Neurological Society this month, Stefanatos found that dextroamphetamine (D-AMPH), a drug commonly used to treat attention deficit hyperactivity disorder, improved the processing of speech among those suffering from Broca’s aphasia and the similar Anomic aphasia.

“Improving a patient’s attention and working memory may allow them to better focus and process information during therapy sessions,” said Stefanatos. “Attention is critically important for learning and relearning skills, and could be helpful in forging new neural pathways in the brain.”

Stefanatos's research explores the nature and basis of neurogenic language disorders integrate neuropsychological/neurolinguistic approaches to the study of brain function with advanced functional neuroimaging techniques, such as brain electrical source localization and functional magnetic resonance imaging.

Stefanatos’ recent study looked at the use of D-AMPH in ten aphasia patients. All were also given a placebo for comparison purposes. In each condition, participants were asked to make decisions about different types of speech sounds (vowels, consonant-vowels) and complex tones. Their brain’s electrical response to each was recorded via an electroencephalogram (EEG).

Those who took the D-AMPH had a strong reaction to the sounds — even to consonant-vowel sounds, which are more often difficult for individuals with aphasia to process.

“This tells us that D-AMPH may help the left hemisphere of the brain regain the ability to perform its functions,” said Stefanatos. “Understanding why the drug is having this effect allows us to start to think about how to tailor treatments to make them more effective or explore alternative drugs or drug combinations.”

Stefanatos said he and his team chose to look at this particular drug because in patients with ADHD it has been shown to stimulate the release of dopamine and epinephrine, which help in attention and learning. But he notes that some people aren’t good candidates for this particular drug.

“Now that we have a rudimentary understanding of why the drug may work to enhance the results of therapy, our next step is to look at dose effects and perhaps other drugs with more favorable side effect profiles,” said Stefanatos.

With collaborators from the departments of Radiology and Physical Medicine and Rehabilitation, Stefanatos will next study functional magnetic resonance imaging to explore the effects of D-AMPH on cerebral metabolism and where in the brain of individuals with aphasia it has the greatest effect.

Other authors on this study are Andrew DeMarco at Temple University, Robert Segal at McGill University in Quebec, and Arthur Gershoff, M.D. and Y. Ieuji of the Moss Rehab Stroke and Neurological Diseases Program, part of the Albert Einstein Healthcare Network in Philadelphia. This work was funded by grants from the National Institute of Health and the Pennsylvania Department of Health.

His interdisciplinary work on acquired epileptiform aphasia and regressive autism resulted in passage of a congratulatory resolution (HR 307) by the General Assembly of the Commonwealth of Pennsylvania in 1997, in recognition of his scientific and clinical contributions. He has extended his work in this area to studies seeking to understand brain plasticity and the changes that accompany recovery from stroke and other cerebrovascular insults to the brain. Among the studies currently under way, he is examining the extent to which pharmacologic and behavioral interventions promote adaptive functional and structural changes in brain organization and enhance recovery of function. He received his bachelor's degree in Psychology from McGill University in Montreal and his doctorate in Clinical Neuropsychology from the University of Oxford in England. While based at the MRC Neuropsychology Unit (situated in the Oxford University Department of Clinical Neurology), he developed a special interest in the problems of individuals with acquired aphasia and in the inexplicable failure to acquire language experienced by some children (Specific Language Impairment). In collaboration with colleagues at the University Laboratory of Physiology, he developed novel methods of recording brain electrical responses in humans to rapidly changing complex sounds. He applied this steady-state auditory evoked responses paradigm in studies directed to understanding the neurobiological basis of speech perception problems seen in developmental language disorders and some forms of acquired aphasia in children.

Stefanatos has written numerous articles published in scientific journals and has authored several chapters in textbooks in the field of neuropsychology and cognitive neuroscience. These have covered conditions such as attention deficit hyperactivity disorder, autism, Asperger's disorder, developmental language disorder, and aphasia. His editorial responsibilities have included reviewing research papers for "Brain and Development, “Brain and Cognition, Neuropsychologia, Biological Psychiatry, Child Neuropsychology, Journal of Child Psychology and Psychiatry, the Journal of Developmental and Learning Disorders, Neuropsychiatric Genetics, Neurocase, Clinical Neuropsychologist, and Journal of Neuropsychological Rehabilitation. He has also served on scientific review committees for the National Institute of Health.

Stefanatos has received funding from the National Institute on Deafness and Communicative Disorders, the National Institute of Child Health and Development, the Pennsylvania Department of Health and the Albert Einstein Society.

Marie Bernard

Marie Bernard to Speak at Women's Health Research Symposium at Temple March 26

Director of the National Institute on Aging is a leading expert on medical care for an aging population 

MEDIA CONTACT: Paul Statt, Paul Statt Communications, 413-244-7456, paulstatt@paulstatt.com

PHILADELPHIA, Feb. 9--Marie Bernard, the Deputy Director, National Institute on Aging (NIA), will deliver the keynote address on "Healthy Aging" at the fifth annual Women's Health Interdisciplinary Research Symposium at 8 a.m on Thursday, March 26 in Mitten Hall at Temple University, as part of week-long celebration of research at the university.

The daughter of two physicians, Bernard earned her medical degree at the University of Pennsylvania School of Medicine and completed her residency at Temple University Hospital, where she was chief resident. She held several positions at Temple's School of Medicine, starting as an instructor in medicine, then serving as an associate professor in internal medicine, director of medical clinics and assistant admissions dean. In 1990, the University of Oklahoma recruited her to build its geriatrics education and research programs. Until her move to the NIA, she was the founding director of Oklahoma's Reynolds Department of Geriatric Medicine, which launched in 1997. At the time, it was only the third department of geriatrics in the nation. In addition to founding and directing the department, Bernard also served as Associate Chief of Staff (ACOS) for Geriatrics and Extended Care at the Oklahoma City Veterans Affairs Medical Center.

Bernard's research, which she has pursued in addition to administrative and other roles, has focused on nutrition and functioning in older adults, with particular emphasis on ethnic minorities. She has published widely on geriatric care, nutrition, medication issues and health problems among minorities. She was a member of the NIA's National Advisory Council on Aging, and chaired its Minority Task Force. She has also been a member of the American Geriatrics Society's Board of Directors, President and Chair of the Board of the Association of Directors of Geriatric Academic Programs, and a member of the Institute of Medicine committee that wrote the groundbreaking "Retooling for an Aging America: Building the Health Care Workforce," released in April. Among the committee's key findings: The nation's healthcare workforce is too small and unprepared to meet the needs of its rapidly growing population of older adults.

The annual Women's Health Interdisciplinary Research Symposium is taking place as a part of Research Week, from Monday, March 23 through Friday, March 27, at Temple University. Sponsored by the Office of the Senior Vice President for Research and Strategic Initiatives, Research Week offers five days of lecturers, colloquia, presentations and performances, culminating on Friday, March 27 with an address by 2008 Nobel Chemistry Laureate Martin Chalfie, who discovered green fluorescent proteins.

David Post

In 1787, Thomas Jefferson, then the American Minister to France, had the "complete skeleton, skin & horns" of an American moose shipped to him in Paris and mounted in the lobby of his residence as a symbol of the vast possibilities contained in the strange and largely unexplored New World. Inspired by his Jeffersonian intellectual curiosity about Jefferson's eccentric efforts, David Post, professor of law in the Beasley School of law at Temple University and one of the nation's leading Internet scholars, asked why--and what Jefferson might have to say in the 21st Century.  In Search of Jefferson's Moose ($27.95, Oxford University Press, New York 2009) is a pithy, colorful exploration of the still mostly undiscovered territory of cyberspace--what it is, how it works, and how it should be governed.

What law should the Internet have, and who should make it? What are we to do, and how are we to think, about online filesharing and copyright law, about Internet pornography and free speech, about controlling spam, and online gambling, and cyberterrorism, and the use of anonymous remailers, or the practice of telemedicine, or the online collection and dissemination of personal information? How can they be controlled? Should they be controlled? And by whom? Post presents the Jeffersonian ideal--small self-governing units, loosely linked together as peers in groups of larger and larger size--as a model for the Internet and for cyberspace community self-governance. Deftly drawing on Jefferson's writings on the New World in Notes on the State of Virginia , Post draws out the many similarities (and differences) between the two terrains, vividly describing how the Internet actually functions from a technological, legal, and social perspective as he uniquely applies Jefferson's views on natural history, law, and governance in the New World to illuminate the complexities of cyberspace.
