In 2008, a themed section of Australian Humanities Review began the task of establishing the emerging field of ‘Rural Cultural Studies’. As the editors pointed out, ‘contemporary cultural studies researchers internationally and in Australia have been massively biased towards urban popular cultures’.

The hydrophilic, long-chain diamine PEGda (O,O′-bis(2-aminoethyl)octadeca(ethylene glycol)), when complexed with cis-protected Pt(II) ions afforded water-soluble complexes of the type [Pt(N,N)(PEGda)](NO3)2 (N,N = N,N,N′,N′-tetramethyl-1,2-diaminoethane (tmeda), 1,2-diaminoethane (en), and 2,2′-bipyridine (2,2′-bipy)) featuring unusual 62-membered chelate rings. Equimolar mixtures containing either the 16-mer duplex DNA D2 or the single-stranded D2a and [Pt(N,N)(PEGda)]2+ were analyzed by negative-ion ESI-MS. Analysis of D2-Pt(II) mixtures showed the formation of 1:1 adducts of [Pt(en)(PEGda)]2+, [Pt(tmeda)(PEGda)]2+ and the previously-described metallomacrocycle [Pt2(2,2′-bipy)2{4,4′-bipy(CH2)44,4′-bipy}2]8+ with D2; the dinuclear species bound to D2 most strongly, consistent with its greater charge and aromatic surface area. D2 formed 1:2 complexes with the acyclic species [Pt(2,2′-bipy)(Mebipy)2]4+ …

We investigated molecular motions on a picoseconds timescale of 1,2-Dimyristoyl-sn- Glycero-3-Phosphocholine (DMPC) model membranes as a function of hydration by using elastic and quasielastic neutron scattering. Two different hydrations corresponding to approximately nine and twelve water molecules per lipid were studied, the latter being the fully hydrated state. In our study we focused on head group motions by using chain deuterated lipids. Information on in-plane and out-of-plane motions could be extracted by using solid supported DMPC multilayers. Our studies confirm and complete former investigations by K¨onig et al. and Rheinst¨adter et al. who describe the dynamics of lipidmembranes, but did …

The isolation of two new Stemona alkaloids, 1-hydroxyprotostemonine and stemocurtisine N-oxide, and a new benzofuran, stemofuran L, from the root extracts of Stemona curtisii is reported. The major known alkaloids from this plant extract, stemocurtisine, stemocurtisinol, and oxyprotostemonine, were also isolated along with oxystemokerrine N-oxide. The nonalkaloid components of this extract included a new benzofuran derivative, stemofuran L, the known stemofurans F, J, and K, dihydro-γ-tocopherol, and stigmasterol. Stemocurtisine and stemocurtisinol were converted to their respective N-oxides by oxidation. Stemocurtisine was converted to a tetracyclic derivative by oxidative cleavage of the γ-butyrolactone ring, while stemocurtisinol gave a novel lactam derivative …

Lipid model membranes such as 1,2-Dimyristoyl-sn-Glycero-3-Phosphocholine (DMPC) serve as role models for their more complex counterparts in biological systems. Quasielastic neutron scattering (QENS) [1-3], inelastic neutron scattering (INS) [4] and neutron spin echo spectroscopy (NSE) [5] have been employed to study local as well as collective dynamics of these membranes on a ps-ns time scale. Most of these studies lack a systematic investigation of the behavior of the model membranes in dependence on their hydration. We now started a detailed investigation of hydration effect on model membrane systems. The complexity of the dynamics can be further reduced by selective deuteration, …
