The Sentinel Lymph Node Territories Of The Whole Body And Their Clinical Implications: A Human Cadaver Study
Funder
National Health and Medical Research Council
Funding Amount
$602,984.00
Summary
Lymph gland screening with isotopes (Lymphoscintigraphy) has revealed unexpected pathways of cancer spread. This study, using an X-ray injection technique in human cadavers, is re-evaluating the outdated Melways Roadmap of lymph vessel pathways. The aims are to give accurate predictions of cancer spread, explain unusual clinical manifestations and to provide a new method of treating lymphoedema, the incapacitating swelling of limbs that may complicate lymph gland surgery or radiotherapy.
Morphometric Analysis Of Normal Airway Structure In Childhood And The Influence Of A History Of Asthma On This Structure

Summary
The architectural structure of the airways of the lung is thought to have profound effects on airway function. Changes in this structure are believed to be partly responsible for limiting the flow of air into the lung in conditions such as constant wheezing, bronchitis and asthma. Pathological studies carried out on adult lungs have shown that the structure of the airways is indeed altered in patients with lung disease when compared with patients with no history of breathing difficulties. For ex ....The architectural structure of the airways of the lung is thought to have profound effects on airway function. Changes in this structure are believed to be partly responsible for limiting the flow of air into the lung in conditions such as constant wheezing, bronchitis and asthma. Pathological studies carried out on adult lungs have shown that the structure of the airways is indeed altered in patients with lung disease when compared with patients with no history of breathing difficulties. For example, the walls of the airways are much thicker in patients with lung disease. This thickening means that the airways are much narrower and therefore not able to carry as much air as in people with healthy lungs. In addition, the muscle within the airway wall, which is normally very sparse, is much denser in people with asthma and bronchitis. Thus, the airways can be squeezed closed more easily. It is not known if these changes are present in children who have lung disease. X-rays and sophisticated breathing tests suggest that these children may also have thicker walls and more muscle in their airways. The major difficulties in assessing whether such changes are present in children, is the lack of information on the normal structure in infants; how this changes as they grow to adulthood; or if there are any gender differences. This project aims to obtain this information from the airways of male and female children from 0-18 years. This information can then be used as a basis for comparison with the structure found in children with lung disease, in particular asthma, and therefore assist in making assessments as to the cause of their breathing difficulties. With more knowledge about these causes, we will be in a better position to design new and better treatments and produce ways of preventing them ever occurring.Read moreRead less

Summary
The NHMRC and the Australian National Oral Health Plan have identified health inequalities as a critical health issue. Dental caries in children increasingly has become concentrated in disadvantaged population groups. While previous studies have documented socioeconomic gradients in oral health, few have sought to explain the reasons underlying those inequalities. By taking advantage of two existing datasets of child oral health in Australia, collected in 1992 and 2002, we will be able to quanti ....The NHMRC and the Australian National Oral Health Plan have identified health inequalities as a critical health issue. Dental caries in children increasingly has become concentrated in disadvantaged population groups. While previous studies have documented socioeconomic gradients in oral health, few have sought to explain the reasons underlying those inequalities. By taking advantage of two existing datasets of child oral health in Australia, collected in 1992 and 2002, we will be able to quantify change in socioeconomic inequalities in oral health, and identify population-wide exposures to preventive practices and social circumstances that may have contributed to that change.Read moreRead less
Heart failure (HF) is the most common cause of hospital admission in those over 65y, and has significant morbidity and mortality. We need to develop new strategies to treat HF. Plasma vasopressin (AVP) levels are elevated in HF, and may contribute to adverse outcomes. This proposal will assess the utility of blocking the vasopressin V1 and V2 receptors in a rat model of HF. We shall also measure AVP in humans with HF. The results of this work may result in new approaches to treat HF patients.

Australia's policy of mandatory detention has been criticised at home and abroad. This research will bring together both empirical and reflective material about that policy by those who have seen its effects first hand, which will make an important contribution to national self-definition. The research process itself will bring together practitioners who have worked in the field, many of whom have expressed the need for recording their experiences, and guidelines as to how to practice in the future when human rights issues form a part of clinical practice. As such, the project will contribute to other areas of healthcare where such issues are present, such as indigenous health, mental health, and the care of other vulnerable populations.

Obesity is a major predisposing factor for a variety of life threatening diseases such as type II diabetes, hypertension, and coronary heart disease with their enormous costs both socially and economically. Development of human obesity and its related metabolic disorders generally develops over a long period and eventually becomes a chronic condition. Generally, chronic consumption of high-energy food in excess of expenditure leads to excessive fat accumulation and promotes the development of obesity. However, under these conditions, some individuals become obese, while others remain lean indicating that variation in susceptibility is an important determinant of the development of obesity. It is apparent that those individuals resistant to obesity have a more effective defence system against excessive fat accumulation. Using the animal models developed in our laboratory, the proposed research aims to search for the differences in the central regulation between the mice resistant or susceptible to the development of obesity. The outcomes we expect to achieve include: 1) better understanding of central factors controlling energy balance, 2) clarification of the central factors responsible for dysregulation of this system by chronic consumption of a high-energy diet, and 3) identification of those factors contributing to prevention against such dysregulation. Further, according to our previous study [XFH1, 2, 3], we propose to use the drugs targeting on the specific receptor subtypes to test reversibility of chronic high energy diet-induced obesity.Read moreRead less

Global progress against malnutrition has been too slow to allow the Millennium Development Goals on hunger to be met. International research has proposed that these failures are due to the fact that the livelihood options available to poor households are increasingly misaligned from their traditional channels for ensuring food and nutrition security. This argument is highly influential in international development research, underpinning calls for nutrition-sensitive development interventions. The aim of this project is to test the proposition using original survey data collected from 1 600 households in rural Myanmar. This will be the first project of this kind, aiming to shed crucial insight into this issue at this vital moment in Myanmar's transition.Read moreRead less
