Fragment-Based Screening By Protein Crystallography: Successes And Pitfalls, Zorik Chilingaryan, Zhou Yin, Aaron J. Oakley

Faculty of Science - Papers (Archive)

Fragment-based drug discovery (FBDD) concerns the screening of low-molecular weight compounds against macromolecular targets of clinical relevance. These compounds act as starting points for the development of drugs. FBDD has evolved and grown in popularity over the past 15 years. In this paper, the rationale and technology behind the use of X-ray crystallography in fragment based screening (FBS) will be described, including fragment library design and use of synchrotron radiation and robotics for high-throughput X-ray data collection. Some recent uses of crystallography in FBS will be described in detail, including interrogation of the drug targets β-secretase, phenylethanolamine N-methyltransferase, phosphodiesterase …

Competition Strength Of Two Significant Invasive Species In Coastal Dunes, K French Jan 2012

Competition Strength Of Two Significant Invasive Species In Coastal Dunes, K French

Faculty of Science - Papers (Archive)

To investigate the effect of increased nutrient availability on competition amongst invasive and native plants, I measured changes in above and below ground biomass of Chrysanthemoides monilifera spp. rotundata (bitou bush) and Asparagus aethiopicus (asparagus fern) competing with two native species, Banksia integrifolia and Ficinia nodosa, under highand low-nutrient regimes. Bitou bush, as a primary invader, was competitive under all conditions lowering the growth of native species in both high and low nutrients. Asparagus fern as a secondary invader, did not influence growth of native species but responded, like bitou bush, to high nutrients. Native species were generally negatively …

Concern in recent decades about human impacts on Earth's climate has led to the need for improved and expanded measurement capabilities of greenhouse gases in the atmosphere. In this paper we describe in detail an in situ trace gas analyser based on Fourier Transform Infrared (FTIR) spectroscopy that is capable of simultaneous and continuous measurements of carbon dioxide (CO2), methane (CH4), carbon monoxide (CO), nitrous oxide (N2O) and 13C in CO2 in air with high precision. High accuracy is established by reference to measurements of standard reference gases. Stable water isotopes can …

Becoming Differently Modern: Geographic Contributions To A Generative Climate Politics, Lesley M. Head, Christopher R. Gibson Jan 2012

Becoming Differently Modern: Geographic Contributions To A Generative Climate Politics, Lesley M. Head, Christopher R. Gibson

Faculty of Science - Papers (Archive)

Anthropogenic climate change is a quintessentially modern problem in its historical origins and discursive framing, but how well does modernist thinking provide us with the tools to solve the problems it created? On one hand even though anthropogenic climate change is argued to be a problem of human origins, solutions to which will require human actions and engagements, modernity separates people from climate change in a number of ways. On the other, while amodern or more-than-human concepts of multiple and relational agency are more consistent with the empirical evidence of humans being deeply embedded in earth surface processes, these approaches …

Atmospheric deposition represents a major input of mercury to surface environments. The phase of mercury (gas or particle) has important implications for its removal from the atmosphere. We use long-term observations of reactive gaseous mercury (RGM), particle-bound mercury (PBM), fine particulate matter (PM2.5), and temperature at five sites in North America to derive an empirical gas-particle partitioning relationship log10(K-1) = (10 ± 1) − (2500 ± 300)/T where K = (PBM/PM2.5)/RGM with PBM and RGM in common mixing ratio units, PM2.5 in μg m−3, and T in …

Australia's Black Saturday Fires - Comparison Of Techniques For Estimating Emissions From Vegetation Fires, Clare Paton-Walsh, Louisa K. Emmons, Christine Wiedinmyer Jan 2012

Australia's Black Saturday Fires - Comparison Of Techniques For Estimating Emissions From Vegetation Fires, Clare Paton-Walsh, Louisa K. Emmons, Christine Wiedinmyer

Faculty of Science - Papers (Archive)

We present a comparison of techniques for estimating atmospheric emissions from fires using Australia's 2009 "Black Saturday" wildfires as a case study. Most of the fires started on Saturday the 7th of February 2009 (a date now known as "Black Saturday") and then spread rapidly, fanned by gale force winds, creating several firestorms and killing 173 people. The fires continued into early March, when rain and cooler conditions allowed the fires to be extinguished. In this study, we compare two new techniques (and one more established method) to estimate the total emissions of a number of atmospheric trace gases from …

The Kimberley region of northwest Australia contains one of the World's largest collections of rock art characterised by two distinct art forms; the fine featured anthropomorphic figures of the Gwion Gwion or Bradshaw paintings, and broad stroke Wandjina figures. Luminescence dating of mud wasp nests overlying Gwion Gwion paintings has confirmed an age of at least 17,000 yrs B.P. with the most recent dates for these paintings from around the mid-Holocene (5000 to 7000 yrs B.P.). Radiocarbon dating indicates that the Wandjina rock art then emerged around 3800 to 4000 yrs B.P. following a hiatus of at least 1200 yrs. …

Inhibition of GSL (glycosphingolipid) synthesis reduces Aβ (amyloid β-peptide) production in vitro. Previous studies indicate that GCS (glucosylceramide synthase) inhibitors modulate phosphorylation of ERK1/2 (extracellular-signal-regulated kinase 1/2) and that the ERK pathway may regulate some aspects of Aβ production. It is not clear whether there is a causative relationship linking GSL synthesis inhibition, ERK phosphorylation and Aβ production. In the present study, we treated CHO cells (Chinese-hamster ovary cells) and SH-SY5Y neuroblastoma cells, that both constitutively express human wild-type APP (amyloid precursor protein) and process this to produce Aβ, with GSL-modulating agents to explore this relationship. We found that three …

Background: Devil Facial Tumour Disease (DFTD) is a unique clonal cancer that threatens the world's largest carnivorous marsupial, the Tasmanian devil (Sarcophilus harrisii) with extinction. This transmissible cancer is passed between individual devils by cell implantation during social interactions. The tumour arose in a Schwann cell of a single devil over 15 years ago and since then has expanded clonally, without showing signs of replicative senescence; in stark contrast to a somatic cell that displays a finite capacity for replication, known as the "Hayflick limit". Methodology/Principal Findings: In the present study we investigate the role of telomere length, measured as …

Generally, sigmoid curves are used to describe the growth of animals over their lifetime. However, because growth rates often differ over an animal's lifetime a single curve may not accurately capture the growth. Broken-stick models constrained to pass through a common point have been proposed to describe the different growth phases, but these are often unsatisfactory because essentially there are still two functions that describe the lifetime growth. To provide a single, converged model to age animals with disparate growth phases we developed a smoothly joining two-phase nonlinear function (SJ2P), tailored to provide a more accurate description of lifetime growth …

Half a century of research into the physiology and biochemistry of sun–shade acclimation in diverse plants has provided reality checks for contemporary understanding of thylakoid membrane dynamics. This paper reviews recent insights into photosynthetic efficiency and photoprotection from studies of two xanthophyll cycles in old shade leaves from the inner canopy of the tropical trees Inga sapindoides and Persea americana (avocado). It then presents new physiological data from avocado on the time frames of the slow coordinated photosynthetic development of sink leaves in sunlight and on the slow renovation of photosynthetic properties in old leaves during sun to shade and …

The chemical constituents and biological activities of Corydalis crispa (Fumariaceae) were investigated for the first time. The phytochemical study resulted in the isolation of nine known isoquinoline alkaloids: protopine (1), 13-oxoprotopine (2), 13-oxocryptopine (3), stylopine (4), coreximine (5), rheagenine (6), ochrobirine (7), sibiricine (8) and bicuculline (9), with complete NMR data for 2 and 3 provided here for the first time. Crude extracts exhibitedsignificant anti-inflammatory (p < 0.01) activity against TNF-alpha production in LPS activated THP-1 cells. The acetylcholinesterase inhibitory activity of compounds 2, 4 and 7 and the antiplasmodial activity of compound 5 against P. falciparum strains TM4/8.2 and K1CB1 (multidrug resistant strain) are reported here for the first time. Stylopine (4) did not show antimalarial activity against the K1CB1 strain in contrast to a previous report. This study generated a scientific basis for the use of this plant in Bhutanese traditional medicine, either individually or in combination with other medicinal ingredients to treat a broad range of disorders. This study also identified compound 5 as potential new antimalarial lead compound.

Time series of total column abundances of hydrogen chloride (HCl), chlorine nitrate (ClONO2), and hydrogen fluoride (HF) were determined from ground-based Fourier transform infrared (FTIR) spectra recorded at 17 sites belonging to the Network for the Detection of Atmospheric Composition Change (NDACC) and located between 80.05° N and 77.82° S. By providing such a near-global overview on ground-based measurements of the two major stratospheric chlorine reservoir species, HCl and ClONO2, the present study is able to confirm the decrease of the atmospheric inorganic chlorine abundance during the last few years. This decrease is expected following the 1987 Montreal Protocol and …

Participation in sporting or recreational programs can be unattainable for many disadvantaged young people. Encouraging regular cycling is an important public health strategy to increase participation in physical activity and expand personal transport options for marginalised youth. Perceptions and attitudes toward cycling were explored in eight focus groups, involving 47 young people who were experiencing or at risk of homelessness in central and south-western Sydney, Australia. The benefits of cycling for physical activity, personal transport, independence and social inclusion were recognised. Barriers to regular cycling included compliance with mandatory helmet legislation; a lack of cycling skills and experience; a paucity …

Public health ethics has emerged and grown as an independent discipline over the last decade. It involves using ethical theory and empirical analyses to determine and justify the right thing to do in public health. In this paper, we distinguish public health ethics from clinical ethics, research ethics, public health law and politics. We then discuss issues in public health ethics including: how to weigh up the benefits, harms and costs of intervening; how to ensure that public health interventions produce fair outcomes; the potential for public health to undermine or promote the rights of citizens; and the significance of …

How Do Dentists Understand Evidence And Adopt It In Practice?, Alexandra Sbaraini, Stacy M. Carter, R Wendell Evans Jan 2012

How Do Dentists Understand Evidence And Adopt It In Practice?, Alexandra Sbaraini, Stacy M. Carter, R Wendell Evans

Faculty of Social Sciences - Papers (Archive)

Although there is now a large evidence-based dentistry literature, previous investigators have shown that dentists often consider research evidence irrelevant to their practice. To understand why this is the case, we conducted a qualitative study. Objective: Our aim was to identify how dentists define evidence and how they adopt it in practice. Methods: A qualitative study using grounded theory methodology was conducted. Ten dentists working in eight dental practices were interviewed about their experience and work processes while adopting evidence-based preventive care. Analysis involved transcript coding, detailed memo writing, and data interpretation. Results: Findings revealed that dentists' direct observations - …

Experiences Of Dental Care: What Do Patients Value?, Alexandra Sbaraini, Stacy M. Carter, R Wendell Evans, Anthony Blinkhorn

Faculty of Social Sciences - Papers (Archive)

Background Dentistry in Australia combines business and health care service, that is, the majority of patients pay money for tangible dental procedures such as fluoride applications, dental radiographs, dental fillings, crowns, and dentures among others. There is evidence that patients question dentists' behaviours and attitudes during a dental visit when those highly technical procedures are performed. However, little is known about how patients' experience dental care as a whole. This paper illustrates the findings from a qualitative study recently undertaken in general dental practice in Australia. It focuses on patients' experiences of dental care, particularly on the relationship between patients …

In this article, we provide a description of the good in health promotion based on an empirical study of health promotion practices in New South Wales, the most populous state in Australia. We found that practitioners were unified by a vision of the good in health promotion that had substantive and procedural dimensions. Substantively, the good in health promotion was teleological: it inhered in meliorism, an intention to promote health, which was understood holistically and situated in places and environments, a commitment to primary rather than secondary prevention and engagement with communities more than individuals. Procedurally, the good in health …

Risk factors associated with canine obesity include the amount of walking a dog receives. The aim of this study was to investigate the relationships between canine exercise requirements, socio-demographic factors, and dog-walking behaviors in winter in Calgary. Dog owners, from a cross-sectional study which included a random sample of adults, were asked their household income, domicile type, gender, age, education level, number and breed(s) of dog(s) owned, and frequency and time spent dog-walking in a usual week. Canine exercise requirements were found to be significantly (P < 0.05) positively associated with the minutes pet dogs were walked, as was the owner being a female. Moreover, dog walking frequency, but not minutes of dog walking, was significantly associated with residing in attached housing (i.e., apartments). Different types of dogs have different exercise requirements to maintain optimal health. Understanding the role of socio-demographic factors and dog-related characteristics such as exercise requirements on dog-walking behaviors is essential for helping veterinarians and owners develop effective strategies to prevent and manage canine obesity. Furthermore, encouraging regular dog-walking has the potential to improve the health of pet dogs, and that of their owners.

Maintaining the attention to bodily difference human and animal ontology has long been constructed on rigid physical characterizations seemingly untouched by culture. In "Reframing the Ethical Issues in Part-Human Animal Research," Haber and Benham (2012) call into question most of the formal elements of essentialism that an earlier mode of thought took for granted. Two views on the nature of human and interspecies animal bodies are in contention here. The first offers an argument grounded in the essential developmental properties of human and animal material and biological systems such that giving life to "animals with human derived material," exemplified by …

Animals-As-Patients: Improving The Practice Of Animal Experimentation, Jane Johnson, Christopher J. Degeling

Faculty of Social Sciences - Papers (Archive)

In this paper we propose a new way of conceptualizing animals in experimentation: the animal-as-patient. Construing and treating animals as patients offers a way of successfully addressing some of the entrenched epistemological and ethical problems within a practice of animal experimentation directed to human clinical benefit. This approach is grounded in an epistemological insight and builds on work with so-called "pet models". It relies upon the occurrence and characterization of analogous human and nonhuman animal diseases, where, if certain criteria of homology and mechanism are met, the animal simultaneously becomes a patient and a spontaneous model of the human disease.

Community based service-learning (CBSL) integrates experiential learning and academic goals with organised service activities designed to meet the objectives of community partners (Bringle & Hatcher, 1995). Although research remains inconclusive regarding the benefits of student outcomes, CBSL has been endowed with the potential to enhance (1) academic learning, (2) foster civic responsibility, (3) develop life skills and (4) transform student attitudes (Eyler, 2002). However, there is little research to support claims that benefits are mutual amongst host counterparts (Edwards et al., 2001; Ward & Wolf-Wendell, 2000).

What does it mean to think about the ethics of health promotion? When most of us think 'ethics' we think of the Human Research Ethics Committee applications required for research projects. But I'm thinking of something quite different here: the ethics of health promotion practice.

As other authors have argued, sometimes these questions are ignored in health promotion in …

For more than a decade there has been growing concern about global reductions in physical activity and increases in sedentary behaviours. Initially, it was unclear whether children would be protected from this trend. Perhaps children's playfulness and associated activity levels would act as a protective factor. There is now compelling evidence that children's activity levels are quite sensitive to environmental factors. For example, a recent US study of activity levels in preschoolers concluded that "...the characteristics of the school have a much greater influence on a child's activity level while in school than do the child's personal demographic characteristics" (Pate …
