Exposure to toxic chemicals while in the womb or in early life may weaken a baby's immune system response to the tuberculosis (TB) vaccine, researchers say.
The study focused on two common toxins: PCBs, an industrial chemical; and DDT, used in pesticides. These so-called "persistent" pollutants are not easily broken down and remain a health threat years after being banned.
PCBs were banned in the United States in 1979. DDT is banned in the United States, but is still used in some countries to control malaria-carrying mosquitoes, the study authors, from the University of Rochester in New York, said in a university news release.
"There are thousands of pollutants similar to PCBs and DDT with unknown health implications," study leader Dr. Todd Jusko, assistant professor in the departments of environmental medicine and public health services, said in the news release. "Our work provides a foundation for how these types of chemicals affect the developing immune system in infants around the world."

Fetal exposure to two chemicals -- polychlorinated biphenyls, or PCBs, and DDE, a product of the breakdown of the insecticide DDT -- can dampen infants' immune response to the tuberculosis vaccine, according to a new study of mothers and children.
Both chemicals have been banned in many countries, including the United States, but are considered persistent pollutants, which pose health risks long after being introduced into the environment, can accumulate. The effects of such pollutants can pass between species through the food chain.
PCBs were used in manufacturing and consumer products in the United States until 1979, but most people have detectable PCB concentrations in their blood. DDT was banned in the United States in 1972, though many countries still use it to control the spread of malaria by mosquitoes.

B&B Professor Harold Smith and Oyagen's Drug Development Highlighted on Local TV for World Aids Day
Friday, December 4, 2015
OyaGen, a small medical research firm off Jefferson Road in Henrietta, has used federal grants for its HIV drug discovery programs with the goal of finding a cure. Dr. Harold Smith, Professor of Biochemistry & Biophysics at the University of Rochester, and the company's founder, president and CEO got his start as a molecular biologist studying heart disease.
"It became clear to me that the things we were doing to study heart disease and find out why things were happening translated directly into the HIV research arena," Smith said.
By 2010, things kicked into high gear. Advanced robotics were added allowing scientists to work with advanced chemistries. They've now identified a weak point in the HIV virus that's never been exploited before. Vif is a viral defense HIV releases into cells it infects. It destroys the body's natural defense against infections. OyaGen discovered a way to defeat HIV by disabling Vif.
"If we can proceed along track, we will be looking at entering clinical trials within a completely different way of approaching the virus and the disease within three years," Smith said.

Researchers in the Department of Biomedical Genetics have unraveled one of the key molecular mechanisms that regulate stem cell behavior, a discovery that could provide important insight into regenerative medicine and certain forms of cancer.
The study – led by Benoit Biteau, Ph.D. – appears in the journal Cell Reports, and was conducted in fruit flies, or drosophila. While diminutive in stature, fruit flies have proven to be an invaluable research tool and have made oversized contributions to medicine, particularly in the fields of molecular biology and genetics.
Benoit and his colleagues focused on a transcription factor called Sox21a which is uniquely found in the stem cells of the drosophila intestine. Transcription factors are proteins that control the expression of genes and, subsequently, help regulate cellular activity. Sox21a is the equivalent of Sox2, a transcription factor found in humans that is known to play an important role in the function of stem cells and cell reprogramming.

Kerry O'Banion, M.D., Ph.D., has been awarded $1.8 million from NASA to study whether extended deep space travel places astronauts at risk for neuro-degenerative diseases like Alzheimer's.
The grant is one of nine announced by NASA that will fund research that employ beams of high-energy, heavy ions simulating space radiation. The studies will be conducted in part at the NASA Space Radiation Laboratory at Brookhaven National Laboratory on Long Island. By colliding matter together at very high speeds, the accelerators at Brookhaven can reproduce the radioactive particles found in space.
The studies will seek to better understand and reduce the risks to humans associated with long journeys in deep space, specifically focusing on neurological and cardiovascular diseases and cancer. Understanding the potential health impact of space travel is a priority for NASA as it develops future plans for maned voyages to Mars and other destinations.Read More: NASA Grant Will Explore Impact of Space Travel on the Brain

A new study appearing in the Journal of Neuroinflammation suggests that the brain’s immune system could potentially be harnessed to help clear the amyloid plaques that are a hallmark of Alzheimer’s disease.
This research confirms earlier observations that, when activated to fight inflammation, the brain's immune system plays a role in the removal of amyloid beta, said M. Kerry O'Banion, M.D., Ph.D., a professor in the University of Rochester Department of Neurobiology and Anatomy, the Del Monte Neuromedicine Institute, and the lead author of the study.
We have also demonstrated that the immune system can be manipulated in a manner that accelerates this process, potentially pointing to a new therapeutic approach to Alzheimer's disease.
The findings are the culmination of years of investigation that were triggered when O'Banion and his colleagues made a surprising discovery while studying mouse models of Alzheimer's disease. They observed that amyloid beta plaques – which scientists believe play a major role in the disease – were being cleared in animals with chronic brain inflammation.

Most of us at one time or another have counted the seconds between a lightning flash and its thunder to estimate distance. University researcher Duje Tadin and his colleagues have discovered that humans can unconsciously notice and make use of sound delays as short as 40 milliseconds (ms) to fine tune what our eyes see when estimating distances to nearby events.
Much of the world around us is audiovisual, says Tadin, Associate Professor of Brain and Cognitive Sciences and senior author of the study.
Although humans are primarily visual creatures, our research shows that estimating relative distance is more precise when visual cues are supported with corresponding auditory signals. Our brains recognize those signals even when they are separated from visual cues by a time that is too brief to consciously notice.
For the study, published in PLOS ONE, researchers used projected three-dimensional (3D) images to test the human brain's ability to use sound delays to estimate the relative distance of objects.

Edward Brown's research is a mixture of photonics, microscopes and a little nudge from his mom.
Brown, who teaches biomedical engineering at the University of Rochester Medical Center, has built a laser-and-microscope device to study how likely cancer cells will spread throughout the body. Specifically, he's looking at how likely cancer cells have spread inside breast cancer patients who already have had the tumor removed.
Learning more about the cell movement, called metastasis, is key to a larger overtreatment problem that Brown is trying to fix.
When patients first realize they have breast cancer, it's unclear whether the cancer cells have spread, so doctors recommend chemotherapy as a precaution. However, Brown and other medical researchers believe patients are being overtreated because doctors are giving chemo to patients who may not need it.Read More: URMC using photon laser for cancer research
Clerio Vision licenses ground-breaking approach to vision correction developed by Huxlin, Knox and Ellis
Friday, October 23, 2015
LASIK revolutionized vision correction in the 1990s. Now, a new technology arising from research conducted by Wayne Knox, Professor of Optics and Physics; Krystel Huxlin, Professor of Ophthalmology; and Jonathan Ellis, Assistant Professor of Mechanical Engineering, may do the same, notes UR Ventures Technology Review.
LIRIC (Laser Induced Refractive Index Change), this ground-breaking method also uses a laser to correct the optical properties of the eye, but that's where the similarities to LASIK end.
The older technology uses two lasers and includes cutting the cornea to create a flap and then pulling that flap back to expose the inner cornea. A laser is then applied to ablate and reshape the corneal tissue to achieve the desired focus. The corneal flap is repositioned and the healing process begins. Complications are rare, but as with any surgery, are a concern. Fear of complications and of having one's eye cut are big reasons why less than 2 percent of people who are eligible for LASIK undergo the procedure.
The LIRIC method uses a laser at a much lower power and does not cut or remove any tissue. Instead, it is a non-invasive procedure that alters the refractive index of the corneal tissue to correct vision. Since the procedure doesn't thin the cornea like LASIK, it may be repeated many times over the course of a patient's lifetime as the eye grows and changes.
This technology has been licensed to Clerio Vision, Inc., a local startup poised to bring this new treatment to market. Clerio was started by a team of entrepreneurs with proven track records - Mikael Totterman (VirtualScopics, iCardiac), Alex Zapesochny (Lenel, iCardiac), Scott Catlin (AMO, Abbott Medical Optics - and now with UR Ventures), and Sasha Latypova (VirtualScopics, iCardiac). The company successfully concluded an oversubscribed Series A round of fundraising with participation from three venture capital firms, and is considering a Series B round to further accelerate product and clinical development. They have proven efficacy in animal models and hydro-gels (contact lenses), and plan to conduct human studies early in 2016.

Protease inhibitors are a class of antiviral drugs that are commonly used to treat HIV, the virus that causes AIDS. Scientists at the University of Nebraska Medical Center designed a new delivery system for these drugs that, when coupled with a drug developed at the University of Rochester School of Medicine and Dentistry, rid immune cells of HIV and kept the virus in check for long periods. The results appear in the journal Nanomedicine: Nanotechnology, Biology and Medicine.
While current HIV treatments involve pills that are taken daily, the new regimens' long-lasting effects suggest that HIV treatment could be administered perhaps once or twice per year.
Nebraska researcher Howard E. Gendelman designed the investigational drug delivery system–a so–called
nanoformulated protease inhibitor. The nanoformulation process takes a drug and makes it into a crystal, like an ice cube does to water. Next, the crystal drug is placed into a fat and protein coat, similar to what is done in making a coated ice–cream bar. The coating protects the drug from being degraded by the liver and removed by the kidney.
When tested together with URMC–099, a new drug discovered in the laboratory of UR scientist Harris A. (Read More: Experimental Treatment Regimen Effective Against HIV
Handy) Gelbard M.D., Ph.D., the nanoformulated protease inhibitor completely eliminated measurable quantities of HIV. URMC–099 boosted the concentration of the nanoformulated drug in immune cells and slowed the rate at which it was eliminated, thereby prolonging its therapeutic effect.

Much like birds fly in flocks to conserve energy, dolphins swim in pods to mate and find food, and colonies of ants create complex nests to protect their queens, immune cells engage in coordinated behavior to wipe out viruses like the flu. That’s according to a new study published in the journal Science by researchers at the University of Rochester School of Medicine and Dentistry.
The findings reveal, for the first time, how immune cells work together to get to their final destination – the site of an injury or infection. The body is expansive and a virus or bacteria can take hold in any number of locations: the lungs, the throat, the skin, the stomach or the ear, just to name a few. How do immune cells, specifically the ones that are responsible for killing foreign invaders, know where to go?

EHSC Welcomes Dr. Martha Susiarjo
Tuesday, September 1, 2015
The Environmental Health Sciences Center (EHSC) would like to welcome Dr. Martha Susiarjo to URMC.
Dr. Martha Susiarjo applies her background in epigenetics to understanding whether epigenetic regulation of genes contributes to gene-environment interaction during early development. She joins us as Assistant Professor from the University of Pennsylvania, where she recently completed her postdoc studying environmental estrogens and regulation of imprinted genes (genes contributed by only one parent). Dr. Susiarjo employs a mouse model to understand the mechanism(s) by which environmental exposures – obesogenic endocrine disrupting chemicals in particular – during in utero development can shape the future health outcomes of the offspring. She hopes to identify mechanisms in order to better inform exposure prevention efforts.
Dr. Susiarjo looks forward to collaborating with center members to utilize her expertise in epigenetics, especially DNA methylation, in various models of environmental perturbations. She also hopes collaborative efforts can elucidate how nutritional intervention may provide protective effects on environment-induced developmental outcomes.
Carney lab looks beyond inner ear in quest for better hearing aids
Friday, August 28, 2015
Most hearing aids on the market today are designed to mimic what happens in our inner ear - specifically the amplifying role of the outer hair cells.
However, the lab of Laurel Carney, Professor of Biomedical Engineering,
is studying what happens beyond the inner ear - in the complex network of auditory nerve fibers that transmit the inner ear's electrical signals to the brain, and in the
auditory center of the midbrain, which processes those signals.
Therein lies the key to creating hearing aids that not only make human speech louder but clearer, Carney believes.
An important focus of her research uses a combination of physiological and behavioral studies, and computer modeling, to study the 30,000 auditory nerve fibers on each side of our
brain that transmit electrical signals from the inner ear. Critical to this is the initial
transduction of mechanical energy to electrical signals that occurs in the inner hair cells of the inner ear's organ of Corti.
This is critical for shaping the patterning of responses in the auditory nerves, and the patterning of those responses at this first level, where the signal comes into the brain, has a big effect on the way the mid brain responds to the relatively low frequencies of the human voice, Carney explained.
In people with healthy hearing, the initial transduction results in a wide contrast in how various auditory nerve fibers transmit this information.
The responses of some fibers are dominated by a single tone, or harmonic, within the sound; others respond to fluctuations that are set up by the beating of multiple harmonics, Carney said. In the mid brain,
neurons are capable of assimilating this contrast of fluctuating and nonfluctuating inputs across varying frequencies. They begin the process of parsing out the sounds of speech and any other vocalizations that involve low frequencies. A better understanding of how this process works in the midbrain, Carney believes, could yield new strategies for designing hearing aids.
A lot of people have tried to design hearing aids based just on what is going on in the inner ear, but there's a lot of redundancies in the information generated there. We argue that you need to step back and, from the viewpoint of the midbrain, focus on what really matters. It's the pattern of fluctuations in the auditory nerve fibers that the midbrain responds to. The sort of strategies we're suggesting are not intuitive. The idea of trying to restore the contrast in the fluctuations across different frequency channels has not been tried before. The burden is on us
to prove that it works, she added.
To that end, Carney works closely with Joyce McDonough, Professor of Linguistics,
in exploring how auditory nerve fiber transmissions play a role in coding speech sounds. Her lab also works closely with that of Jong-Hoon Nam, Assistant Professor of Mechanical Engineering and of Biomedical Engineering, whose inner-ear studies were described in this newsletter last week. Carney shares what her lab is learning about the interface of auditory nerve fiber signaling with the brain, and in return,
we try to include in our models a lot of the nonlinear properties of the inner ear that he (Nam) has been working on. By interacting with his lab, we hope to continue to
modernize our model as he discovers more, Carney said.
New patent issued for Professor Hocking
Wednesday, August 26, 2015
The patent titled “Chimeric Fibronectin Matrix Mimetics and Uses Thereof” (US 9,072,706) has recently been assigned to the University of Rochester with inventors Denise C. Hocking, Ph.D. (Pharmacology and Physiology, BME, RCBU) and Daniel Roy, Ph.D. (BME PhD 2012 alumnus). The patent relates to a series of recombinant fibronectin peptide mimetics developed to promote wound repair. The technology falls under a new and exciting class of therapies known as wound biologics. The primary commercial application for this technology is to promote healing of hard-to-heal or chronic wounds, including diabetic, venous, and pressure ulcers, which impose a significant health care burden worldwide. Encouraging results from recent studies indicate that topical application of these fibronectin peptide mimetics to full-thickness excisional wounds in diabetic mice accelerates wound closure and promotes granulation tissue deposition, remodeling, and re-vascularization. Denise Hocking is an Associate Professor of Pharmacology and Physiology and of Biomedical Engineering. Daniel Roy is currently a post-doctoral fellow at the US Army Institute of Surgical Research in San Antonio, TX.

Dr. Charles Duffy
A small company started by a neuroscientist at the University of Rochester has moved closer to providing doctors with what he says is a simple,
computer-based tool to help detect early signs of Alzheimer's disease or other forms of dementia.
Cerebral Assessment Systems has received marketing approval from the
U.S. Food and Drug Administration for Cognivue, a cognitive-assessment tool that functions somewhat like a video game. A patient can perform the
inexpensive and simple test while a time-strapped primary-care physician tends to other patients. The 10-minute, non–invasive examination can detect
subtle lapses in the brain’s perceptual ability that may signal the early stages of mental decline caused by dementia.
The federal government's approval to market the device comes as Alzheimer's researchers everywhere step up the pursuit for easier and more
inexpensive ways to identify dementia in its earliest stages.
Look, there is a late-life tsunami of late-life cognitive decline coming at us, and health-care providers are standing on the beach,

Researchers at SUNY Stony Brook and The University of Rochester think so.
Sleeping in the lateral, or side position, as compared to sleeping on one’s back or stomach, may more effectively remove brain waste and prove to be an important practice to help reduce the chances of developing Alzheimer’s, Parkinson’s and other neurological diseases, according to researchers at Stony Brook University.
In the paper, “The Effect of Body Posture on Brain Glymphatic Transport,” Dr. Benveniste and colleagues used a dynamic contrast MRI method along with kinetic modeling to quantify the CSF-ISF exchange rates in anesthetized rodents’ brains in three positions – lateral (side), prone (down), and supine (up).
Dr. Benveniste and first-author Dr. Hedok Lee, Assistant Professor in the Departments of Anesthesiology and Radiology at Stony Brook developed the safe posture positions for the experiments. Their colleagues at the University of Rochester, including Lulu Xie, Rashid Deane and Maiken Nedergaard, PhD, used fluorescence microscopy and radioactive tracers to validate the MRI data and to assess the influence of body posture on the clearance of amyloid from the brains.Read More: Could Your Sleep Position Help Reduce Alzheimer’s Risk?
Environmental Medicine News: EHSC Grant Renewal, New Appointment
Wednesday, July 29, 2015
Great news from Environmental Medicine—its Environmental Health Sciences Center (EHSC) core grant was recently renewed for the 41st straight year. The department ushered in the $7.5 million, five-year, EHSC award from the National Institute of Environmental Health Sciences (with a remarkable score of 12). She is also overseeing the setup of EHSC’s new epigenetics core facility. Funding for the Center began in 1975 and has been continuously supported by the NIH for costs related to infrastructure, career development, biostatistics, and to support collaborations across research departments at URMC.
Environmental Medicine also hired a new scientist with an interest in reproductive toxicity and epigenetics, a hot field concerned with investigating the environmental factors (such as the endocrine-disrupting chemical bisphenol A) that cause changes in gene expression across generations. Martha Susiarjo, Ph.D., completed a post-doctoral fellowship at the University of Pennsylvania and will join the UR as an assistant professor Sept. 1. She brings an NIH K99 award and expertise to the new epigenetics core facility.
The EHSC will celebrate 50 years of research with a two-day symposium Sept. 23-24, which will include a Science Café Series at the Pittsford Barnes & Noble, a poster session in Flaum Atrium, and a full slate of presentations at URMC from faculty and local civic leaders. Planning is under way; stay tuned for more details.

Researchers Pinpoint Brain's Audiovisual Processing Center
A new study is helping scientists more precisely understand how the brain stitches together sensory information such as sound and images, insight that could shed new light on conditions such as Autism. The research, which appears in the Journal of Neuroscience, identifies an area of the brain in the frontal lobe responsible for working memory and sensory integration.
Work in our laboratory is aimed at understanding how auditory and visual information are integrated since we know this process is crucial for recognizing objects by sight and sound, communicating effectively, and navigating through our complex world, said Lizabeth Romanski, Ph.D., an associate professor in the University of Rochester Department of Neurobiology and Anatomy and co-author of the study.
Read More: Work of Liz Romanski Recognized by the University Research Community
Our recent study demonstrates that the prefrontal cortex plays an essential role in audiovisual working memory, and when this area is switched off our ability to remember both the auditory and visual cues is impaired, said Bethany Plakke, Ph.D., a postdoctoral fellow in the Romanski lab and co-author of this study.

Infants can use their expectations about the world to rapidly shape their developing brains, researchers have found.
A series of experiments with infants 5 to 7 months old has shown that portions of babies' brains responsible for visual processing respond not just to the presence of visual stimuli, but also to the mere expectation of visual stimuli, according to researchers from the University of Rochester and the University of South Carolina.
That type of complex neural processing was once thought to happen only in adults—not infants—whose brains are still developing important neural connections.
We show that in situations of learning and situations of expectations, babies are in fact able to really quickly use their experience to shift the ways different areas of their brain respond to the environment, said Lauren Emberson, who conducted the study at the University of Rochester's Baby Lab while a research associate with Richard Aslin in the department of brain and cognitive sciences.

Researcher Wins Auditory Neuroscience Award
Tuesday, July 7, 2015
Laurel Carney, a professor of Biomedical Engineering, has been recognized for her work by the premier scientific organization in the field of acoustics. The Acoustical Society of America has awarded Carney the William and Christine Hartmann Prize in Auditory Neuroscience.
It's truly a great honor to receive an award created by Bill and Christine Hartmann, two of my role models, said Carney.
I welcome the challenge to emulate their life of discovery, presentation, publication, service, and education throughout the world.
William and Christine Hartmann established the award with a donation to recognize and honor
research that links auditory physiology with auditory perception or behavior in humans or other animals. William Hartmann is a physicist, psychoacoustician, and former president of the Acoustical Society of America. His contributions to the field involved pitch perception, signal detection, modulation detection, and the localization of sound.
In her research lab, Carney is working to better understand how the brain translates sounds into patterns of electrical impulses. By studying physiology, human hearing, and computer models, Carney hopes to learn how the brain distinguishes sounds in noisy environments and why even a small degree of hearing loss can lead to major problems. Her ultimate goal is to develop effective strategies to help people who have experienced hearing loss.
Carney earned her M.S. and Ph.D. degrees in electrical engineering at the University of Wisconsin-Madison. She was an associate professor of biomedical engineering at Boston University and professor of biomedical engineering at Syracuse University before joining the faculty at the University of Rochester in 2007, where she serves as professor in three departments—biomedical engineering, neurobiology and anatomy, and electrical and computer engineering.

Our brains track moving objects by applying one of the algorithms your phone's GPS uses, according to researchers at the University of Rochester.
This same algorithm also explains why we are fooled by several motion-related optical illusions, including the sudden
break of baseball's
Like GPS, our visual ability, although quite impressive, has many limitations, said the study's coauthor, Duje Tadin, associate professor of brain and
cognitive sciences at the University of Rochester.
The new open-access study published in PNAS shows that our brains apply an algorithm, known as a Kalman filter, when tracking
an object's position. This algorithm helps the brain process less than perfect visual signals, such as when objects move to the periphery of our visual field where acuity is low.Read More: Duje Tadin explains how understanding GPS can help you hit a curveball

Suzanne Haber leads a research team to investigate OCD. She says the disease is characterized by intrusive,
ruminating thoughts (obsessions), and impulses to carry out repetitive behaviors (compulsions), despite the awareness by most patients that these behaviors don't make sense.
The goal of a new $10 million grant awarded to the scientists is to improve our understanding of the brain networks that play a central role in
obsessive-compulsive disorder (OCD).
Together with leading mental health researchers at four other institutions in the U.S., they will pinpoint specific abnormalities within the brain circuits that
are associated with the disease and use this information to guide new treatment options for the three million-plus Americans who live with the disorder.
The five-year grant from the National Institute of Mental Health (NIMH) establishes a new
Silvio O. Conte Center for Basic and Translational Mental Health Research at the University of Rochester. Conte Centers are designed to bring scientists with diverse
but complimentary backgrounds together to improve the diagnosis and treatment of mental health disorders.

The Democrat and Chronicle was one of 12 Gannett newspapers that partnered with a USA Today investigation, Biolabs in Your Backyard, about the concerns and dangers that can accompany biomedical research.
The investigation focused on more than 200 high-containment biomedical labs around the nation that are equipped to handle select agents and other dangerous research.
Research involving select agents is considered by the federal government to be the most worrisome biomedical lab work because of potential health risks and security concerns, especially since some of these agents and toxins can be used in biological warfare.
The University of Rochester has one high-containment lab at its medical center that in recent years has worked with Francisella tularensis, which is a Tier I select agent, the highest level of concern.

A new $1.7 million grant will bring together a team of researchers to study – an ultimately thwart – the chain reaction that occurs in the body after cardiac arrest that can ultimately lead to brain damage and death.
“While the biological sequence of events is triggered by cardiac arrest, the death and disability associated with this event is the result of a broader systemic injury caused the initial loss of blood flow and subsequent tissue inflammation once blood circulation is restored,” said University of Rochester Medical Center neurologist Marc Halterman, M.D., Ph.D., the principal investigator of the study.

Professors Dalecki and Hocking Research Wins Best Paper Award at SPIE-DSS
Wednesday, May 6, 2015
The latest research by Professor Diane Dalecki (BME, RCBU) and Professor Denise C. Hocking (Pharmacology & Physiology, BME, RCBU) was recognized with the Best Paper Award at the Micro- and Nanotechnology Sensors, Systems, and Applications Conference of the SPIE Defense + Security Symposium held recently in Baltimore, Maryland. Their invited paper titled “Guiding Tissue Regeneration with Ultrasound In Vitro and In Vivo” detailed three biomedical ultrasound technologies under development in their laboratories to stimulate tissue formation and regeneration. Co-authors of the paper included Sally Child, Carol Raeman, and BME graduate students Eric Comeau and Laura Hobbs. One technology under development employs forces within an ultrasound standing wave field to provide a noninvasive approach to spatially pattern endothelial cells and thereby guide the development of complex microvessel networks. A second technology uses ultrasound to site-specifically control the microstructure of collagen fibers within engineered hydrogels to direct cell function. The third line of research focuses on developing ultrasound as a therapeutic approach to enhance tissue regeneration in chronic wounds. These ultrasound technologies offer new solutions to key challenges currently facing the fields of tissue engineering, biomaterials fabrication, and regenerative medicine.
The SPIE DSS 2015 Defense + Security Symposium consisted of 32 separate conferences spanning 5 days with over 1200 total presentations. Conferences focused on a wide range of topics of interest to defense and security, including imaging, sensing, photonics, materials, and biomedical applications. The Symposium is the leading meeting for scientists, researchers and engineers from industry, military, government agencies, and academia throughout the world. The Micro- and Nanotechnology Sensors, Systems, and Applications Conference is one of the two largest conferences within the entire Defense + Security Symposium, and Professors Hocking’s and Dalecki’s presentation was one of over 100 invited presentations in the conference.

A team of researchers led by Associate Professor, Dr. David Rich (Public Health Sciences & Environmental Medicine) studied birth weights before, during and after the Beijing Olympics, during which widespread pollution reduction efforts were instated. They found infants born shortly after the Olympics had significantly higher birth weights than infants born in other years. The researchers compiled information from 83,672 term births (37 to 42 weeks gestational age at birth) to mothers in four urban districts in Beijing. They compared birth weights for mothers whose eighth month of pregnancy occurred during the 2008 Olympics/Paralympics with those whose eighth month of pregnancy occurred at the same time of year in the years before (2007) and after (2009) the games when pollution levels were at their normally higher levels. They found that the babies born in 2008 were on average 23 grams larger than those in 2007 and 2009.

David Williams, the William G. Allyn Professor of Medical Optics, Dean for research and Director of the Center for Visual Science
A team of researchers at the University of Rochester is designing an optical system to image responses to light of large numbers of individual cells in the retina, with the objective of
accelerating the development of the next generation of cures for blindness. The Rochester team and their partners will receive $3.8 million from the National Eye Institute over the next five years.
The new instrumentation we are developing builds on technology we had developed previously to improve vision through laser refractive surgery and contact lenses, as well as to
diagnose retinal disease, said Rochester's principal investigator David Williams.
This is the first time we have designed instrumentation specifically to develop and test therapies
to restore vision in the blind.
The National Eye Institute (NEI), part of the National Institutes of Health, announced the awards as part of its Audacious Goals
Initiative to tackle the most devastating and difficult to treat eye diseases. The central goal is to restore vision by regenerating neurons and neural connections in the eye and visual system.
The initiative places special emphasis on cells of the retina, including the light-sensitive rod and cone photoreceptors, and the retinal ganglion cells, which connect photoreceptors to
the brain via the optic nerve.

Medications are available to treat many of the symptoms of neurodegenerative diseases like multiple sclerosis and Parkinson’s disease, but there is no drug or other therapy that improves the memory and cognitive problems that often plague patients. A new start-up company, built around research conducted at the University of Rochester School of Medicine and Dentistry, hopes to change that.
Camber NeuroTherapeutics Inc., founded based on discoveries made in the laboratories of Harris "Handy" A. Gelbard, M.D., Ph.D. and Stephen Dewhurst, Ph.D., plans to attack the cognitive component of neurodegenerative diseases using a completely new approach: stopping the inflammation in the brain, so-called neuroinflammation, that impairs the function of nerve cells and the vast networks they create. These neural networks allow us to store and recall memories, plan and prioritize, focus on particular tasks, and process sensory information.Read More: URMC Start-up Takes Aim at Memory and Cognitive Problems

Kraft Macaroni & Cheese -that favorite food of kids, packaged in the nostalgic blue box—will soon be free of yellow dye. Kraft announced Monday that it will remove artificial food coloring, notably Yellow No. 5 and Yellow No. 6 dyes, from its iconic product by January 2016. Instead, the pasta will maintain its bright yellow color by using natural ingredients: paprika, turmeric and annatto (the latter of which is derived from achiote tree seeds).
The company said it decided to pull the dyes in response to growing consumer pressure for more natural foods. But claims that the dyes may be linked to attention-deficit hyperactivity disorder (ADHD) in children have also risen recently, as they did years ago, putting food dyes under sharp focus once again. On its Web site Kraft says synthetic colors are not harmful, and that their motivation to remove them is because consumers want more foods with no artificial colors.
Bernard Weiss, professor emeritus of the Department of Environmental Medicine at the University of Rochester Medical Center who has researched this issue for decades, says he is frustrated that the FDA has not acted on the research showing the connection between artificial dyes and hyperactivity. Read More: Does Artificial Food Coloring Contribute to ADHD in Children?
All the evidence we have has showed that it has some capacity to harm, he says.
In Europe that's enough to get it banned because a manufacturer has to show lack of toxic effects. In this country it's up to the government to find out whether or not there are harmful effects. Weiss supports banning artificial colors until companies have evidence that they cause no harm. Like most other scientists in this field, he thinks more research, particularly investigating dyes' effects on the developing brain, is imperative.

Celebrating 50 Years at URMC and Saying Goodbye: Victor Laties
Friday, April 10, 2015
Dr. Victor Laties, Professor Emeritus
In 1965, a young Victor Laties left Johns Hopkins for the University of Rochester and never looked back. In 2015, Vic celebrated his 50th year at the University of Rochester Medical Center-a feat not surpassed by many. Primarily in the department of Environmental Medicine, Vic has touched many lives over the years with his great work ethic, caring attitude, his love of toxicology, and his fantastic photos that have graced the Environmental Medicine, Environmental Health Sciences Center (EHSC), and Toxicology websites over the past 50 years.
The first director of the toxicology training grant, that is now in his 37th year, Vic has been integral to it's success and has created many memories and passed down a wealth of knowledge to hundreds of students.

A University of Rochester team found a way to make chemotherapy more effective, by stopping a cellular quality-control mechanism, according to a study published today in Nature Communications.
The mechanism is known as NMD (nonsense-mediated mRNA decay), and scientists found that exposing breast cancer cells to a molecule that inhibits NMD prior to treatment with doxorubicin, a drug used to treat leukemia, breast, bone, lung and other cancers, hastens cell death.
The research team, led by Lynne E. Maquat, Ph.D., director of the Center for RNA Biology at the University of Rochester, acknowledges that the work is in the early stages and a long way from being applied in humans. But, they believe their data provide insights that could lead to new treatment strategies for cancer patients in the future.

Lynne E. Maquat, Ph.D. received the 2015 Gairdner International Award for the discovery and mechanistic studies of nonsense-mediated mRNA decay, a cellular quality control mechanism that derails the production of unwanted proteins in the body that can disrupt normal processes and initiate disease. She is one of five scientists honored with the award, which is given every year to recognize the achievement of medical researchers whose work contributes significantly to improving the quality of human life.
The J. Lowell Orbison Endowed Chair and Professor of Biochemistry and Biophysics at the University of Rochester Medical Center, Maquat is known around the world for her work on nonsense-mediated mRNA decay, which is critically important in both normal and disease states. She is considered the uncontested pioneer on the subject and in 2011 was elected to the National Academy of Sciences for her exceptional research, which has been published in more than 130 peer-reviewed scientific articles.
Maquat is the first scientist from upstate New York to receive the Gairdner International Award, which is recognized for its rigorous peer-led selection process. A panel of active Canadian scientists reviews all nominations and passes their recommendations to a board of two dozen senior scientists from across Canada, the United States, Europe, Australia and Japan. After in-depth study and review, board members cast votes for the nominees whose achievements rise above all others in their field. According to the Gairdner Foundation, of the 313 winners to date, 82 have gone on to receive a Nobel Prize in Physiology or Medicine, a testament to the quality of the awardees.

Mini-symposium for Young Investigators in Memory of Dr. Robert Marquis to be Held March 10, 2015
Monday, March 2, 2015
Robert Marquis Mini-Symposium for Young Investigators
Tuesday, March 10, 2015
Hynes Convention Center, Boston, MA
About Robert Marquis
Dr. Robert E. Marquis, PhD, was chair of the Department of Microbiology and Immunology at the University of Rochester School of Medicine and Dentistry, and a beloved teacher to many students who trained at the medical school and at the university’s College of Arts and Sciences. He died in January 2014 at the age of 80. Originally from Ontario, Canada, “Bob” earned his M.S. and PhD degrees from the University of Michigan in Ann Arbor. He spent two years as a post-doctoral fellow at the University of Edinburgh in Scotland, where he studied under the guise of Peter Mitchell, a British biochemist who was awarded the 1978 Nobel Prize in Chemistry.
Bob began his career at the University of Rochester in 1963 as a senior instructor in Microbiology and was continuously funded by the National Institutes of Health until his retirement as a professor in 2012. During his early years at the medical school, he studied energy transduction – how cells and bacteria develop energy from food. From the 1970s until the end of his career he focused on oral streptococci, a type of bacteria present in the mouth that are major contributors to tooth decay. He had a secondary appointment in the Center for Oral Biology and his work on the effects of fluoride on cavity-producing bacteria earned him international recognition and the 2006 Distinguished Scientist Award for Research in Dental Caries from the International Association for Dental Research.
As passionate as Bob was about his research, he was equally, if not more passionate about the colleagues, trainees, and students he worked with every day. He influenced the lives of many graduate students who considered him to be a remarkable colleague, mentor and friend. It is not surprising then that many of Bob’s graduate students went on to assume distinguished careers in academia, industry, or public health service.
Bob's influence also included undergraduate students on the University of Rochester’s River Campus, where he was a founding director of the Undergraduate Program in Biology and Medicine. This program combines the College of Arts and Sciences and the School of Medicine and Dentistry to provide courses for undergraduate students with lectures, laboratory work, specialty seminars and research experiences. Bob helped start the program in the early 1980’s and it led to the creation of the Bachelor’s of Science degrees in Biological Sciences, which includes tracks in Biochemistry, Cell and Developmental Biology, Ecology and Evolutionary Biology, Microbiology, Molecular Genetics, and Neuroscience. Thanks to Bob’s work, the program is a major conduit for undergraduate students into research labs at the medical school.
Outside of the University, Bob loved the Rochester Philharmonic Orchestra and was a huge fan of theater, traveling annually to the Shaw Festival in Niagara-on-the-Lake and the Shakespeare Festival in Stratford, Ontario. He was also known to fly to London with his wife on a regular basis to catch plays in London’s West End. Another hobby was custom brewing, an art that he shared and passed on to many.
This mini-symposium honors the memory of the late Robert E. Marquis and the knowledge he eagerly shared with students, trainees and early career faculty members. Its main objective is to promote information exchange among scientists who engage in oral microbiology and immunology research and clinical studies pertaining to oral health and disease, and to provide a forum through which new investigators entering the field can network with established investigators and so create contacts that can help nurture their research progress and productivity.

Do electronic cigarettes help people quit smoking? As the debate continues on that point, a new University of Rochester study suggests that e-cigarettes are likely a toxic replacement for tobacco products.
Emissions from e-cigarette aerosols and flavorings damage lung cells by creating harmful free radicals and inflammation in lung tissue, according to the UR study published in the journal PLOS ONE. Irfan Rahman, Ph.D., professor of Environmental Medicine at the UR School of Medicine and Dentistry, led the research, which adds to a growing body of scientific data that points to dangers of e-cigarettes and vaping.

A new $3.8 million grant will bring together clinical and bench researchers to better understand why individuals who receive anti-retroviral treatment for HIV are at greater risk for heart disease and stroke.
“The good news is that the drugs being used to fight HIV are increasing life expectancy to normal levels,” said University of Rochester neurologist Giovanni Schifitto, M.D., one of the co-leaders of the study. “However, one of the long-term complications is that these treatments, the infection itself, or a combination of the two are increasing risk for cardiovascular and cerebrovascular disease in this population.”Read More: New Study Probes Link Between HIV Drugs and Vascular Disease
