Facial palsy is a devastating condition which has a very significant psychological and cosmetic impact. A simple and effective treatment does not exist for facial palsy. Our research goal is use state-of-the-art technology to define the types and the severity of the underlying nerve injury so that effective treatments can be developed to treat this terrible disorder.

Summary
Traditionally, assessing the growth of the head and face has relied on measuring changes in distances and angles between landmarks on either patients, photographs or x-rays. This is not only slow but also not very accurate. This project will automate the identification of these landmarks on 3D images and quantify normal growth of the head and face. From this we can develop methods of quantifying abnormal growth and use these to understand the impact of surgical interventions on children.

Summary
Birth defects arising from abnormal development of the embryo are a major cause of infant mortality and childhood disabilities. On average 3-4% of liveborn babies have a major congenital abnormality, and of the 15-20% of pregnancies which spontaneously abort, many are due to chromosomal or other developmental anomalies. A common feature of many developmental disorders is dysmorphology of the face, suggesting that genes important in patterning the face are also important in the development of oth ....Birth defects arising from abnormal development of the embryo are a major cause of infant mortality and childhood disabilities. On average 3-4% of liveborn babies have a major congenital abnormality, and of the 15-20% of pregnancies which spontaneously abort, many are due to chromosomal or other developmental anomalies. A common feature of many developmental disorders is dysmorphology of the face, suggesting that genes important in patterning the face are also important in the development of other organ systems. During development of the embryo many of the features of the face derive from a series of swellings termed the pharyngeal arches. The complex processes which determine how the face develops are in a large part controlled by the co-ordinated expression of a large number of genes in the first two of the five pharyngeal arch pairs. While we know some of the genes involved in these processes, the precise mechanisms of craniofacial development are relatively poorly understood. In this project we propose a large scale approach to identifying genes involved in development of the mammalian face and to further delineating their role in development and human disease. This approach takes advantage of state of the art genomic technologies available at the IMB and through existing collaborations overseas. In collaboration with Dr Bento Soares (University of Iowa) we have constructed a library containing all of the genes which are expressed in the first two pairs of pharyngeal arches in the developing mouse embryo. Using an approach designed to eliminate all those genes which are expressed in all or most tissues of the body and play a general role in the body's metabolism, we will select for those genes which play a specific and important role in embryonic development. We will then isolate the human counterparts of these genes and more thoroughly investigate their role in embryonic development and disease.Read moreRead less
Which Treatment Works? New Approaches To Treating Emotion Perception Deficits After Brain Injury

Summary
Many people with traumatic brain injury (TBI) cannot recognise emotions in others. This makes appropriate social behaviour impossible and leads to isolation and unemployment. In this project we compare training that minimises errors (errorless learning) versus training that provides strategies for recognising emotions while allowing errors to occur. Adults with severe TBI will be allocated to one of the two treatments, a social non-therapeutic group or to deferred treatment (waitlist control).
Teeth And Faces Of Australian Twins: A Longitudinal Study

Summary
We are seeking support from the NHMRC to complete a longitudinal study of 250 pairs of twins, both identical and non-identical, whom we have examined at around 4-6 years of age when all the baby teeth were present in the mouth, then again at around 8-10 years of age when both primary and permanent teeth were present. We now plan to examine these twins again at around the age of 11-13 years when all the permanent teeth, except the wisdom teeth, are normally present.

We now plan to examine these twins again at around the age of 11-13 years when all the permanent teeth, except the wisdom teeth, are normally present. Records to be obtained from the twins over the next three years will include dental examinations, dental impressions from which casts can be made, shed primary teeth, and intra- and extra-oral photographs. We will apply modern methods of genetic analysis to determine the importance of genetic and environmental influences on observed variation in several dental and facial features. We will also study the fascinating phenomenon of mirror imaging in twins, where one twin mirrors the other for one or more features. Longitudinal studies of twins, in which a large sample of children is studied over several years, provide a powerful means of determining how genes influence growth and development. As far as we are aware, ours is the only large-scale longitudinal study of dental and facial growth in twins being undertaken in the world at present. Once we have collected all the data and carried out analyses, we will gain a much better understanding of the factors that can influence development of the teeth and face, and be in a much better position to be able to predict those children who are most likely to develop malocclusions in later life.Read moreRead less
Long-term Effect On Offspring Of Low To Moderate Or Binge Drinking During Pregnancy.

Summary
Drinking during pregnancy is a major public health issue. The majority of pregnant women consume some alcohol during pregnancy or the peri-conception period, which is extremely concerning given the potential consequences associated with prenatal alcohol exposure. We will study the effects of low to moderate and binge drinking during pregnancy in early school-aged children by testing for subtle alterations in craniofacial shape, brain structure and function, and neurobehavioural functioning.

Summary
Opioids (in particular morphine) are the gold standard drugs for the relief of most types of moderate to severe pain. Despite the effectiveness of opioids and other analgesics, many people still suffer unrelieved pain. There are 2 main reasons for this. Firstly, there are some types of pain that are refractory to currently used analgesics from the outset, and secondly, chronic conditions may require escalating doses of analgesics for adequate pain relief, and these does may increase until side e ....Opioids (in particular morphine) are the gold standard drugs for the relief of most types of moderate to severe pain. Despite the effectiveness of opioids and other analgesics, many people still suffer unrelieved pain. There are 2 main reasons for this. Firstly, there are some types of pain that are refractory to currently used analgesics from the outset, and secondly, chronic conditions may require escalating doses of analgesics for adequate pain relief, and these does may increase until side effects become intolerable. My studies will provide insight into the reasons that underlie the differential effectiveness of opioids in acute pain conditions, as well as the reasons why opioids lose their effectiveness over time. These studies will also identify molecular targets that may be important for developing analgesics for specific pain conditions. Because the head is the source of many familiar painful conditions, including tooth pain, migraine and temporomandibular disorders, I will be using neurons from the trigeminal ganglion, the part of the nervous system which supplies the sensory innervation to the structures involved in these pain states. By using mice as experimental animals, I will be able to investigate the contribution of neurons that innervate specific parts of the head to these pain states, and study how chronic morphine treatment affects the behavior of these cells. I hope that these studies will provide a basis for designing strategies that improve the effectiveness of existing analgesics, and perhaps lead to the identification of new, better pain relievers.Read moreRead less

Summary
National alcohol guidelines advise women to have no alcohol in pregnancy. However, many find they are unexpectedly pregnant and have been drinking, leading to considerable anxiety. While evidence is clear that heavy drinking is bad for the unborn baby, no-one knows for sure if low or even moderate levels of alcohol in pregnancy are harmful. We will study this important public health problem, following a group of pregnant women through their pregnancy and until their child is two years.
