Multiple sclerosis and neurodegenerative diseases in which cells of the central nervous system (CNS) are lost or damaged are rapidly increasing in frequency, and there is neither effective treatment nor cure to impede or arrest their destructive course. The Epstein-Barr virus is a human gamma-herpesvirus that infects more than 90% of the human population worldwide and persisting for the lifetime of the host. It is associated with numerous epithelial cancers, principally undifferentiated nasopharyngeal carcinoma and gastric carcinoma. Individuals with a history of symptomatic primary EBV infection, called infectious mononucleosis, carry a moderately higher risk of developing multiple sclerosis (MS). It is not known how EBV infection potentially promotes autoimmunity and central nervous system (CNS) tissue damage in MS. Recently it has been found that EBV isolates from different geographic regions have highly conserved BARF1 epitopes. BARF1 protein has the neuroprotective and mitogenic activity, thus may be useful to combat and overcome neurodegenerative disease. BARF1 protein therapy can potentially be used to enhance the neuroprotective activities by combinational treatment with anti-inflammatory antagonists and neuroprotectors in neural disorders.

In 1901, the parliament of the new Commonwealth of Australia passed a series of laws designed, in the words of the Prime Minister Edmund Barton, “to make a legislative declaration of our racial identity”. An Act to expel the large Pacific Islander community in North Queensland was followed by a law restricting further immigration to applicants who could pass a literacy test in a European language. In 1902, under the Commonwealth Franchise Act, “all natives of Asia and Africa” as well as Aboriginal people were explicitly denied the right to vote in federal elections. The “White Australia policy”, enshrined in these laws, was almost universally supported by Australian politicians, with only two members of parliament speaking against the restriction of immigration on racial grounds.

We review our current knowledge of the epidemiology and ecology of avian influenza viruses (AIVs) in Australia in relation to the ecology of their hosts. Understanding the transmission and maintenance of low-pathogenic avian influenza (LPAI) viruses deserves scientific scrutiny because some of these may evolve to a high-pathogenic AIV (HPAI) phenotype. That the HPAI H5N1 has not been detected in Australia is thought to be a result of the low level of migratory connectivity between Asia and Australia. Some AIV strains are endemic to Australia, with Australian birds acting as a reservoir for these viruses. However, given the phylogenetic relationships between Australian and Eurasian strains, both avian migrants and resident birds within the continent must play a role in the ecology and epidemiology of AIVs in Australia. The extent to which individual variation in susceptibility to infection, previous infections, and behavioural changes in response to infection determine AIV epidemiology is little understood. Prevalence of AIVs among Australian avifauna is apparently low but, given their specific ecology and Australian conditions, prevalence may be higher in little-researched species and under specific environmental conditions.

Understanding and resolving conflicts between phenotypic and genetic differentiation is central to evolutionary research. While phenotypically monomorphic species may exhibit deep genetic divergences, some morphologically distinct taxa lack notable genetic differentiation. Here we conduct a molecular investigation of an enigmatic shorebird with a convoluted taxonomic history, the White-faced Plover (Charadrius alexandrinus dealbatus), widely regarded as a subspecies of the Kentish Plover (C. alexandrinus). Described as distinct in 1863, its name was consistently misapplied in subsequent decades until taxonomic clarification ensued in 2008. Using a recently proposed test of species delimitation, we reconfirm the phenotypic distinctness of dealbatus. We then compare three mitochondrial and seven nuclear DNA markers among 278 samples of dealbatus and alexandrinus from across their breeding range and four other closely related plovers. We fail to find any population genetic differentiation between dealbatus and alexandrinus, whereas the other species are deeply diverged at the study loci. Kentish Plovers join a small but growing list of species for which low levels of genetic differentiation are accompanied by the presence of strong phenotypic divergence, suggesting that diagnostic phenotypic characters may be encoded by few genes that are difficult to detect. Alternatively, gene expression differences may be crucial in producing different phenotypes whereas neutral differentiation may be lagging behind.

Women reporting childhood sexual abuse (CSA) that involved actual or attempted penetration may not identify this as their first sexual intercourse. Data were drawn from a population-based, prospective cohort study spanning adolescence to adulthood. CSA prior to age 16 and age of first sexual intercourse with a male were assessed retrospectively. More than half of women reporting CSA in the form of actual or penetrative abuse reported an age of first sexual intercourse at or beyond 16 years. Direct questioning about CSA is needed to accurately ascertain sexual history.

The idea of "Asian space" is undergoing a transformation as a result of rapid technological, economic, social and cultural changes. Following the shift to a global economy and an urban population explosion, Asian cities have been presented as a mainstay of progress, national pride, identity, and positioning on the global stage. The extraordinary pace and intensity of the changes have created a situation unique in the history of urban development. Despite the immense diversity of Asian countries, "Asia-ness" is often treated as a distinctive quality that has emerged from unique recent circumstances affecting Asian urbanizations as a whole. In Future Asian Space, 15 authors explore broad concepts relating to the creation and re-creation of "Asian space" and contemporary Asian identity, and their examination of different sites and research approaches highlights the difficulty of pinpointing what Asia-ness is, or might become. Appropriate design and planning of cities is a critical element in building a sustainable future and coping with environmental, social and cultural problems. Future Asian Space is designed to stimulate interest and engagement in discussions of the Asian city, and its trajectories in architecture and urbanism. The authors' conclusions are important for academics, theorists and practitioners, but they will also intrigue anyone interested in the future of cities and urban life in Asia.

Background: Physical activity (PA) surveillance is an important component of non-communicable disease risk factor monitoring, and occurs through national and international surveillance systems. This review identifies population PA estimates for adults in the Asia-Pacific region, and examines variation in trends and prevalence rates obtained using different PA measures.

Methods: Data were obtained from a MEDLINE search; World Health Organization’s Global Health Infobase; Government websites and reference lists of relevant papers. Inclusion criteria included: national studies or those reporting large scale population-level data; data published from 2000 to 2010 and trend data prior; sample sizes over n = 1000, or fewer subjects in small nations.

Results: In total, 56 population surveys from 29 Asia-Pacific countries were identified. Data on ‘sufficient physical activity’ amongst adults were available from 45 studies (80%), with estimates ranging from 7% to 93% (median 62%, inter-quartile range 40%-85%). For 14 countries, estimates of ‘sufficient activity’ were documented in multiple surveys using different methods, with the largest variation from 18% to 92% in Nepal. Median or mean METminutes/ day, reported in 20 studies, ranged from 6 to 1356. Serial trend data were available for 11 countries (22%), for periods spanning 2-10 years. Of these, five countries demonstrated increases in physical activity over time, four demonstrated decreases and three showed no changes.

Conclusions: Many countries in the Asia-Pacific region collect population-level PA data. This review highlights differences in estimates within and between countries. Some differences may be real, others due to variation in the PA questions asked and survey methods used. Use of standardized protocols and measures, and combined reporting of data are essential goals of improved international PA surveillance.

The relative contribution of genetic and environmental factors in determining variation in life-history traits is of central interest to evolutionary biologists, but the physiological mechanisms underlying these traits are still poorly understood. Here we experimentally demonstrate opposing effects of nutritional stress on immune function, endocrine physiology, parental care, and reproduction between red and black head-color morphs of the Gouldian finch (Erythrura gouldiae). Although the body condition of black morphs was largely unaffected by diet manipulation, red birds were highly sensitive to dietary changes, exhibiting considerable within-individual changes in condition and immune function. Consequently, nutritionally stressed red birds delayed breeding, produced smaller broods, and reared fewer and lower-quality foster offspring than black morphs. Differences in offspring quality were largely due to morph-specific differences in parental effort: red morphs reduced parental provisioning, whereas black morphs adaptively elevated their provisioning effort to meet the increased nutritional demands of their foster brood. Nutritionally stressed genetic morphs also exhibited divergent glucocorticoid responses. Black morphs showed reduced corticosterone-binding globulin (CBG) concentrations and increased levels of free corticosterone, whereas red morphs exhibited reduced free corticosterone levels and elevated CBG concentrations. These opposing glucocorticoid responses highlight intrinsic differences in endocrine sensitivities and plasticity between genetic morphs, which may underlie the morph-specific differences in condition, behavior, and reproduction and thus ultimately contribute to the evolution and maintenance of color polymorphism.

Democracy has never been more popular. It is successfully practiced today in a myriad of different ways by people across virtually every cultural, religious or socio-economic context. The 45 original essays collected in this companion suggest that the global popularity of democracy derives in part from its breadth and depth in the common history of human civilization. It sets a benchmark as the first collection on the history of democracy to present lesser known examples, such as those of ancient China, medieval Islam, colonial Africa or today's Burma, alongside more familiar cases like Athens, the English Parliament, the French Revolution and Women's Suffrage.

Undersdtanding where democracy comes from, and where its greatest successes and most dismal failures lie, is central to democracy's project of inventing ways to address the need of people everywhere to live in peace and freedom and with a say in the decisions that affect their lives.

 This paper examines assumptions about democracy and the role of media held by journalism educators working outside Australia, and the extent to which those assumptions influence teaching styles, regardless of the maturity of the political systems in the nations in question. This paper looks at the work emerging from academics Beate Josephi, Barbie Zelizer, John Nerone, Cherian George and Silvio Waisbord, who argue in Journalism (2012) that there needs to be a change to the understanding by journalism scholars of the central place of journalism in democracy because that view is not global in its perspective. This paper specifically considers Zelizer’s point that “much of the scholarly world in the West – and specifically in the United States – depends directly or indirectly on the presumption of democracy and its accoutrements”. The researcher asks, “what can we learn about our Australian perspective on teaching journalism in the developing world where there may not, yet, be an operating democracy or a form of democracy that replicates the Western liberal model?”

The relationship between toxic marine microalgae species and climate change has become a high profile and well discussed topic in recent years, with research focusing on the possible future impacts of changing hydrological conditions on Harmful Algal Bloom (HAB) species around the world. However, there is very little literature concerning the epidemiology of these species on marine organisms and human health. Here, we examine the current state of toxic microalgae species around the UK, in two ways: first we describe the key toxic syndromes and gather together the disparate reported data on their epidemiology from UK records and monitoring procedures. Secondly, using NHS hospital admissions and GP records from Wales, we attempt to quantify the incidence of shellfish poisoning from an independent source. We show that within the UK, outbreaks of shellfish poisoning are rare but occurring on a yearly basis in different regions and affecting a diverse range of molluscan shellfish and other marine organisms. We also show that the abundance of a species does not necessarily correlate to the rate of toxic events. Based on routine hospital records, the numbers of shellfish poisonings in the UK are very low, but the identification of the toxin involved, or even a confirmation of a poisoning event is extremely difficult to diagnose. An effective shellfish monitoring system, which shuts down aquaculture sites when toxins exceed regularity limits, has clearly prevented serious impact to human health, and remains the only viable means of monitoring the potential threat to human health. However, the closure of these sites has an adverse economic impact, and the monitoring system does not include all toxic plankton. The possible geographic spreading of toxic microalgae species is therefore a concern, as warmer waters in the Atlantic could suit several species with southern biogeographical affinities enabling them to occupy the coastal regions of the UK, but which are not yet monitored or considered to be detrimental.
