QUANTIFICATION AND PARTIAL CHARACTERIZATION OF REGULATORY PEPTIDES IN THE LIVER FLUKE, FASCIOLA-HEPATICA, FROM DIFFERENT MAMMALIAN HOSTS

1. Extracts of the liver fluke, Fasciola hepatica from three different hosts (cow, sheep, rat) have been subjected to radioimmunoassay using antisera to 6 mammalian regulatory peptides.

FASCIOLA-HEPATICA - LOCALIZATION AND PARTIAL CHARACTERIZATION OF TUBULIN

The localisation and distribution of the cytoskeletal protein tubulin in the adult liver fluke Fasciola hepatica have been determined by an indirect immunofluorescence technique using a monoclonal antibody raised against beta-tubulin. Tubulin was demonstrated in the tegumental syncytium and in the tegumental cell bodies and their cytoplasmic connections with the surface syncytium. Immunostaining was also evident in the nerve fibres innervating sensory receptors in the tegument, in the nerve plexus innervating the sub-tegumental musculature and in the cytoplasmic extensions of the nurse cells within the vitelline follicle. Immunoblotting of whole fluke fractions produced a single band corresponding to a molecule of approximately 54 kDa in size. This figure corresponds with previous data obtained on tubulin from other helminth and eukaryotic sources.

ISOLATION AND PARTIAL SEQUENCING OF A PANCREATIC POLYPEPTIDE-LIKE NEUROPEPTIDE FROM THE LIVER FLUKE, FASCIOLA-HEPATICA

1. A pancreatic polypeptide (PP)-immunoreactive neuropeptide has been isolated and partially sequenced from the liver fluke, Fasciola hepatica.

Partial purification of lymphokine activities by iso-electric focusing

A continuous cell-line has been shown to be adaptable to preparation of supernatants containing lymphokine activities. Separation and partial purification of migration inhibiting, colony stimulating and interferon activities from such preparations has been achieved by the use of density gradient iso-electric focusing.

Detection and partial characterization of human B cell colony stimulating activity in synovial fluids of patients with rheumatoid arthritis

The joint fluids of 37 patients with rheumatoid arthritis, eight patients with traumatic injuries to their joints, two patients with Reiter's syndrome and three patients with psoriatic arthritis were tested for the presence of B cell colony stimulating activity (B cell CSA). B cell CSA was found in all of the joint fluids from the patients with rheumatoid arthritis but in none of the joint fluids from patients with traumatic injuries to their joints or in the joint fluids from the patients with Reiter's syndrome. A trace of B cell CSA was found in the joint fluid of one of the three patients with psoriatic arthritis. There was a positive correlation (r = 0.796) between the amount of rheumatoid factor present in the joint fluids and the titre of B cell CSA. This correlation was highly significant (P less than 0.001). The B cell CSA was localized to component(s) with molecular weight ranges 115-129 kD and 64-72 kD and an isoelectric point of 6.8. Its activity was sensitive to reduction with 2-mercaptoethanol and to the oxidising action of potassium periodate.

The EU Constitution of Social Governance in an Economic Crisis: in Defence of a Transnational Dimension to Social Europe

Conventional wisdom has it that the EU is unable to promote viable social integration, which contrasts with its commitments to improving working and living conditions and to social values and goals such as solidarity, social protection and social inclusion. This
article challenges two diff erent standpoints: on the one hand, competitive neoliberalism demands that the EU focuses on economic integration through legally binding internal market and competition rules even if Member States can only maintain a limited commitment to social inclusion, while authors defending the social models unique to the continent of Europe demand that the EU rescinds some of its established legal principles in order to make breathing space for Member States to maintain market correcting social policies. Both positions convene that there should be no genuine social policy at EU level.
This article uses scenarios of widely discussed rulings by the Court of Justice to illustrate that legally enforceable economic integration would prevent most Member States from achieving sustainable health services, labour relations and free university education on the basis of national closure. Since the EU has limited legislative competences to create EU level institutions to balance inequalities, it derives a Constitution of Social Governance from the EU’s values, proposing that the Court of Justice develops its urisprudence into an instrument for challenging European disunion induced by new EU economic governance

Moving beyond the rhetoric of provocation: the French and World War II in the novels of the Hussards (1949-1954)

In the immediate aftermath of the Second World War, only those who had opposed the Germans or were perceived to have done so could freely express themselves. Soon, however, three young writers clearly leaning to the right of the political spectrum – Antoine Blondin, Roger Nimier and Jacques Laurent – dared to challenge their narratives in a series of provocative novels published between 1949 and 1954. Quickly referred to as the Hussards after the publication in 1952 of a famous essay by Bernard Frank, these writers momentarily occupied the literary space left vacant by their older peers. Without denying the provocative, political and subversive dimensions of the Hussards’ war novels, this article will argue that their success was mainly due to the fact that they were largely in line – and not in contradiction – with the ‘horizon of expectations’ of their time (Jauss, 1982).

Scotland’s Curriculum for Excellence: a defence of autonomy and personhood.

Curriculum for Excellence, Scotland’s 3-18 curriculum, has been described as ‘the most significant curricular change in Scotland for a generation’ (McAra, Broadley and McLauchlan, 2013:223). The purpose of the curriculum is ‘encapsulated’ in four capacities in order that learners become i) successful learners, ii) confident individuals, iii) responsible citizens, and iv) effective contributors. With particular reference to these capacities, we explore the principle of autonomy as it pertains to both individual and collective flourishing seeking to disarm commonplace criticisms of autonomy by arguing that it might be put to work in CfE as a potentially multi-dimensional, context-sensitive concept that is relational as well as individual. We conclude that the four capacities lend themselves to re-consideration and re-mapping in pursuit of autonomy and flourishing premised on the principles of liberal personhood.

Improved Efficiency for Partial Oxidation of Methane by Controlled Copper Deposition on Surface-Modified ZSM-5

The mono(μ-oxo) dicopper cores present in the pores of Cu-ZSM-5 are active for the partial oxidation of methane to methanol. However, copper on the external surface reduces the ratio of active, selective sites to unselective sites. More efficient catalysts are obtained by controlling the copper deposition during synthesis. Herein, the external exchange sites of ZSM-5 samples were passivated by bis(trimethylsilyl) trifluoroacetamide (BSTFA) followed by calcination, promoting selective deposition of intraporous copper during aqueous copper ion exchange. At an optimum level of 1–2 wt % SiO2, IR studies showed a 64 % relative reduction in external copper species and temperature-programmed oxidation analysis showed an associated increase in the formation of methanol compared with unmodified Cu-ZSM-5 samples. It is, therefore, reported that the modified zeolites contained a significantly higher proportion of active, selective copper species than their unmodified counterparts with activity for partial methane oxidation to methanol.
