Pre- and post-natal development of the diaphragm

Animal models were used to examine properies of the diaphragm (the main respiratory muscle) before and after birth. The study revealed an insufficient blood supply to the fetus can result in structural and functional damage to the diaphragm. Damage was prevented when the mother was supplemented with creatine during pregnancy.

Religion and post-disaster development

This chapter discusses the role religion and religious organizations can play in development following a natural disaster. The development efforts in Aceh, Indonesia, following the Indian Ocean tsunami in 2004 provide examples of how the nature of Acehnese society, its views on religion, the role of religious organizations in the region, and the activities of aid agencies at the time all contributed the the post-disaster experience in this society.The chapter also considers what the role of faith in such situations might mean for future development efforts, especially in the context of natural disaster.

The development of the institutional investor : the case of Australian life insurers 1945-85

This paper considers the post-war development of asset management practices among Australian life insurers, which have historically been among the largest institutional investors in Australia. A complex process of adaptation and organisational restructuring allowed life insurers to transform from basic investors of policy-holders’ funds to large multifaceted institutional investors in just three decades. Three stages in the development of investment practices are identified. These phases trace the process of expanding existing knowledge bases; diversification; and the acquisition of new skills; consolidation and the integration of these skills into institutional structures; thus completing one cycle of organisational learning and setting the stage for the next.

Post-socialist femininity unleashed/restrained: reconfigurations of gender in Chinese television dramas

In post-socialist China, gender norms are marked by rising divorce rates (Kleinman et al.), shifting attitudes towards sex (Farrer; Yan), and a growing commercialisation of sex (Zheng). These phenomena have been understood as indicative of market reforms unhinging past gender norms. In the socialist period, the radical politics of the time moulded women as gender neutral even as state policies emphasised their feminine roles in maintaining marital harmony and stability(Evans). These ideas around domesticity bear strong resemblance to pre-socialist understandings of womanhood and family that anchored Chinese society before the Communists took power in 1949. In this pre-socialist understanding, women were categorised into a hierarchy that defined their rights as wives, mothers, concubines, and servants (Ebrey and Watson; Wolf and Witke). Women who transgressed these categories were regarded as potentially dangerous and powerfulenough to break up families and shake the foundations of Chinese society (Ahern). This paper explores the extent to which understandings of Chinese femininity have been reconfigured in the context of China’s post-1979 development, particularly after the 2000s.

Notes on astogeny of some Petraliellidae (Bryozoa) from Australia

Members of the bryozoan family Petraliellidae share the capacity to develop basal rhizoids, which anchor the unilaminar, semi-repent parts of the colonies above the substratum, and enable them to overgrow other, competing sessile forms. Little is known of the larval behaviour and settlement, or the early astogeny of species. Ancestrulate colonies of the Australian Tertiary lunulitiform species Smittia biincisa are referred to the genus Riscodopa , and together with Riscodopa paucipora sp. nov. are described and compared with the Recent species R. cotyla and R. parva from New Zealand, and with R. hyalina sp. nov. from New South Wales, Australia. All the Recent species are known to develop basal rhizoids, and an early astogeny similar to that of many other small, rooted bryozoans, comprising the post-metamorphosis development of a binary complex, including rhizoid and feeding elements, is inferred for Riscodopa . Observations on living Hippopetraliella magna from Queensland suggest that both the ancestrular morphology and early astogeny show a capacity for semi-repent growth, even though they do not include rhizoid development. Larvae metamorphose without direct attachment, and the ancestrula develops elongated, partially calcified supporting processes, which raise the early stages of growth above the substratum. A similar kind of ancestrula has been found in preserved specimens of Mucropetraliella ellerii .

The legal recognition of same-sex unions in Australia : a constitutional analysis

The Marriage Equality Amendment Bill 2010 (Cth) currently before federal Parliament amends the present legislative definition of marriage to include same-sex unions. This article provides a constitutional analysis of the scope of the marriage power, s 51(xxi) of the Australian Constitution , through examination of the Bill and other existing and proposed legislation. It argues that if the High Court considered "marriage" to be a constitutionalised legal term of art, it could accommodate post-federation development at common law and in statute to the institution of marriage. It also argues that the presumption in favour of constitutionality ought to be at its strongest with federal legislation determining complex and intractable moral issues. The article explores the constitutional vulnerability of current same-sex union legislation and possible future legislation providing for recognition of the functional equivalent of "marriage". In addition, the article considers the constitutional foundation of a national framework to provide official legal recognition of same-sex relationships.

Novel alginate-enclosed chitosan–calcium phosphate-loaded iron-saturated bovine lactoferrin nanocarriers for oral delivery in colon cancer therapy

Aim: To develop polymeric-ceramic nanocarriers (NCs) in order to achieve oral delivery of the anticancer neutraceutical iron-saturated bovine lactoferrin (Fe-bLf) protein.

Materials & methods: Fe-bLf or paclitaxel (Taxol®) were adsorbed onto calcium phosphate nanocores, enclosed in biodegradable polymers chitosan and alginate. The Fe-bLf or Taxol-loaded NCs indicated as AEC–CP–Fe-bLf or AEC–CP–Taxol NCs, respectively, were made by combination of ionic gelation and nanoprecipitation. Size distribution, morphology, internalization and release profiles of the NCs were studied along with evaluation of in vitro and in vivo anticancer activities and compared with paclitaxel.

Results: AEC–CP–Fe-bLf NCs obtained spherical morphology and showed enhanced endocytosis, transcytosis and anticancer activity in Caco-2 cells in vitro. AEC–CP–Fe-bLf NCs were supplemented in an AIN 93G diet and fed to mice in both prevention and treatment human xenograft colon cancer models. AEC–CP–Fe-bLf NCs were found to be highly significantly effective when given orally, as a pretreatment, 1 week before Caco-2 cell injections. None of the mice from the AEC–CP–Fe-bLf NC-fed group developed tumors or showed any signs of toxicity, while the mice fed the control AIN 93G diet showed normal tumor growth. Fe-bLf or Taxol, when given orally in a diet as nanoformulations post-tumor development, showed a significant regression in the tumor size with complete inhibition of tumor growth later, while intratumoral injection of Taxol just delayed the growth of tumors. The pharmacokinetic and bioavailability studies indicated that nanoformulated Fe-bLf was predominantly present on tumor cells compared to non-nanoformulated Fe-bLf. Fe-bLf-loaded NCs were found to help in absorption of iron and thus may have utility in enhancing the iron uptake during iron deficiency without interfering with the absorption of calcium.

Conclusion: With the promising results of our study, the future potential of NC-loaded Fe-bLf in chemoprevention and in the treatment of human colon cancer, deserves further investigation for translational research and preclinical studies of other malignancies.

Texture and substructure development during post-dynamic softening in Ni-30%Fe austenite

The texture and substructure development during post-dynamic annealing of an austenitic Ni-30%Fe model alloy after complete dynamic recrystallization was investigated using electron back-scattered diffraction (EBSD) and transmission electron microscopy (TEM). A novel mechanism of metadynamic softening is proposed based on the experimental investigation of the grain structure, crystallographic texture and dislocation substructure evolution. The initial softening stage involved rapid growth of the dynamically formed nuclei and migration of the mobile boundaries. The subboundaries within DRX grains progressively disintegrated through dislocation climb and dislocation annihilation, which ultimately led to the formation of dislocation-free grains, while the grain boundary migration gradually became slower. As a result, the DRX texture was largely preserved throughout the annealing process.
