A $1.92 million, five-year R01 Award from the National Institutes of Health will support University of Cincinnati research into the genetic aspects of craniofacial asymmetries that could address a wide spectrum of human conditions, from non-syndromic cleft palate to hemifacial microsomia - conditions that can impair breathing or lead to emotional suffering from distorted appearance. In addition, UC biology researcher Joshua Gross, an assistant professor of biological sciences, was awarded $519,343 from the National Science Foundation to explore the genetic explanation for pigmentation loss in cave animals, which could also hold links to pigmentation changes in humans. Both awards get underway in March.

The researchers are searching for genetic hints by examining a species of eyeless, cave-dwelling fish, Astyanax mexicanus - which has lived in the pitch-black caves of the Sierra de El Abra region of Mexico for millions of years. These fish can be compared with the closely related sighted surface-dwelling fish that are found in Mexico, Texas and New Mexico. Previous research suggests that genetic mutations leading to craniofacial distortions in the cavefish may be similar to human facial abnormalities that often result in painful, corrective surgeries as early as infancy. The closely-related surface-dwelling fish do not have these facial abnormalities.

The funding will support genome-wide mapping which will allow researchers to zero in on the precise region of the genome - specific genes as well as mutations within genes - that will explain these facial asymmetries.

The research project will examine these three levels:

Hello, Gorgeous - The 'Beautiful Reflection,' or Brangelina Factor

Gross says the project began with an appreciation for the fact that symmetry is an important component of human perceptions of facial attractiveness. "This trait evolves under intense sexual selection as a signal of robust physical health and genetic quality in potential mates," states the research proposal. "Think of couples like Brad Pitt and Angelina Jolie, who are admired worldwide for their physical features," says Gross. "The logical flow of this is that facial attractiveness is believed to be an indication of strong genetic composition - a strong mate who will provide for your offspring - and so indirectly there may have been evolutionary pressures acting on our ancestors to maintain facial symmetry in humans.

"Cavefish have naturally lost their eyes over the course of evolution," continues Gross. "The fish can't see one another anymore, so the left and right sides of their faces become uncoupled and begin to exhibit random asymmetries. One of our most surprising discoveries is that there's actually a genetic basis for that asymmetry. Some changes in the genome have resulted in one side of the face developing differently from the other side of the face. Because this process occurs so often, cavefish are a powerful natural model system for learning about this fundamental biological phenomenon of craniofacial symmetry."

The UC researchers have previously found two genes in the cavefish that are closely tied to non-syndromic cleft palate in humans.

New Rochelle, NY, March 11, 2015--Social network sites such as Facebook play an important role in maintaining relationships, including romantic relationships, whether individuals are involved in a geographically close or long-distance romantic relationship. A new study that compares the relative importance of social networks and explores the role they play in helping to maintain a close-by versus a long-distance romantic relationship is 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 April 11, 2015.

In the article "The Use of Social Network Sites for Relationship Maintenance in Long-Distance and Geographically-Close Romantic Relationships," coauthors Cherrie Joy Billedo, Peter Kerkhof, and Catrin Finkenauer, VU University Amsterdam and University of the Philippines, describe differences in the intensity of use and the types of uses of social network sites between the two groups studied. They report how use of social network sites allows individuals to access information about, and monitor the activities of, romantic partners, and how that can be used to gauge a partner's involvement in the relationship and loyalty, with potentially positive or detrimental effects.

"Social network sites are used more frequently by those in long-distance relationships," says Editor-in-Chief Brenda K. Wiederhold, PhD, MBA, BCB, BCN, Interactive Media Institute, San Diego, California and Virtual Reality Medical Institute, Brussels, Belgium. "As long-distance relationships become more common, and continue to succeed, it becomes increasingly valuable to understand the role that technology plays in strengthening or damaging a romantic relationship."

New Rochelle, NY, March 12, 2015-- After giving birth, a woman's estrogen levels drop to lower than usual levels, and while they return to the normal range relatively quickly among women who are not breastfeeding, this hypoestrogenic state may continue in lactating women and cause menopause-like symptoms. The results of a new study comparing vaginal dryness, hot flashes, and mood changes in women who are or are not breastfeeding 3 and 6 weeks after giving birth are reported in Breastfeeding Medicine, the official journal of the Academy of Breastfeeding Medicine published by Mary Ann Liebert, Inc., publishers. The article is available free on the Breastfeeding Medicine website until April 12, 2015.

The article "Application of the Estrogen Threshold Hypothesis to the Physiologic Hypoestrogenemia of Lactation" provides evidence of the impact of breastfeeding on symptoms related to low estrogen levels during the postpartum period. Whereas lactating women showed no differences in the prevalence of hot flashes than non-breastfeeding women, they were significantly more likely to have vaginal dryness, report coauthors Sanjay Agarwal, MD, (University of California, San Diego School of Medicine), Julie Kim, MD (Cedars-Sinai Medical Center, Los Angeles, CA), Lisa Korst, MD, PhD (Childbirth Research Associates, North Hollywood, CA), and Claude Hughes, MD, PhD (Quintiles, Inc., Morrisville, NC).

"The changes in vaginal lubrication secondary to low estrogen levels that can affect breastfeeding mothers may lead to discomfort on sexual intercourse," says Arthur I. Eidelman, MD, Editor-in-Chief of Breastfeeding Medicine. "Physicians should be aware of this problem, which may too often be minimized, and provide appropriate treatment, such as vaginal estrogen cream."

New Rochelle, NY, March 10, 2015--The increased use of engineered nanoparticles (ENMs) in commercial and industrial applications is raising concern over the environmental and health effects of nanoparticles released into the water supply. A timely study that analyzes the ability of typical water pretreatment methods to remove titanium dioxide, the most commonly used ENM, is published in Environmental Engineering Science, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Environmental Engineering Science website until April 10, 2015.

Nichola Kinsinger, Ryan Honda, Valerie Keene, and Sharon Walker, University of California, Riverside, suggest that current methods of water prefiltration treatment cannot adequately remove titanium dioxide ENMs. They describe the results of scaled-down tests to evaluate the effectiveness of three traditional methods--coagulation, flocculation, and sedimentation--in the article "Titanium Dioxide Nanoparticle Removal in Primary Prefiltration Stages of Water Treatment: Role of Coating, Natural Organic Matter, Source Water, and Solution Chemistry".

"As nanoscience and engineering allow us to develop new exciting products, we must be ever mindful of associated consequences of these advances," says Domenico Grasso, PhD, PE, DEE, Editor-in-Chief of Environmental Engineering Science and Provost, University of Delaware. "Professor Walker and her team have presented an excellent report raising concerns that some engineered nanomaterials may find their ways into our water supplies."

"While further optimization of such treatment processes may allow for improved removal efficiencies, this study illustrates the challenges that we must be prepared to face with the emergence of new engineered nanomaterials," says Sharon Walker, PhD, Professor of Chemical and Environmental Engineering, University of California, Riverside.
