Thomas Parmeter: Poetaster and Rhymist

The life of Dr. Thomas Parmeter MD was one of astonishing complexity. Convicted of bigamy in London, he arrived in Sydney on 16 January 1816 and almost immediately resumed his medical practice. In England he had engaged in several literary activities and these too he soon resumed in New South Wales, contributing to contemporary newspapers. A riding accident in 1820 and a stroke in 1825 restricted his ability to practise medicine and so he turned to writing and farming for an income. Neither activity was a financial success and he died in poverty. Herein are collected together his poems, epigrams, aphorisms and quotations from poets and other writers. His contribution to the cultural life of Sydney, though not fully documented, was very likely significant.

A role for protein kinase B beta/Akt2 in insulin-stimulated GLUT4 translocation in adipocytes

Insulin stimulates glucose uptake into muscle and fat cells by promoting the translocation of glucose transporter 4 (GLUT4) to the cell surface. Phosphatidylinositide 3-kinase (PI3K) has been implicated in this process. However, the involvement of protein kinase B (PKB)/Akt, a downstream target of PI3K in regulation of GLUT4 translocation, has been controversial. Here we report that microinjection of a PKB substrate peptide or an antibody to PKB inhibited insulin-stimulated GLUT4 translocation to the plasma membrane by 66 or 56%, respectively. We further examined the activation of PKB isoforms following treatment of cells with insulin or platelet-derived growth factor (PDGF) and found that PKB beta is preferentially expressed in both rat and 3T3-L1 adipocytes, whereas PKB alpha expression is down-regulated in 3T3-L1 adipocytes. A switch in growth factor response was also observed when 3T3-L1 fibroblasts were differentiated into adipocytes. While PDGF was more efficacious than insulin in stimulating PKB phosphorylation in fibroblasts, PDGF did not stimulate PKB beta phosphorylation to any significant extent in adipocytes, as assessed by several methods. Moreover, insulin, but not PDGF, stimulated the translocation of PKB beta to the plasma membrane and high-density microsome fractions of 3T3-L1 adipocytes. These results support a role for PKB beta in insulin-stimulated glucose transport in adipocytes.

The incidence of schizophrenia: A systematic review

There has been a debate on whether or not the incidence of schizophrenia varies across time and place. In order to optimise the evidence upon which this debate is based, we have undertaken a systematicsystematic review of the literature. In this paper we provide an overview of the methods of the review and a preliminary analysis of the studies identified to date. Electronic databases (Medline, Psychlnfo, Embase, LILAC) were systematically searched for articles published between January 1965 and December 2001. The search terms were: (schizo* OR psycho*)AND (incidence OR prevalence). References were also identified from review articles, reference list and by writing to authors. To date we have identified 137 papers drawn from 33 nations. 37 papers in language other than English await translation. The currently included papers have generated 1413 different items of rate information data. In order to analyze these data we have undertaken several sequential filters in order to identify (a) non-overlapping data, (b) birth cohort study versus noncohort studies, (c) overall and sex-specific rates, (d) diagnostic criteria, (e) age ranges, (f) epoch of study, and (g) data on migrant or other special interest groups. In addition, we will examine the impact of urbanicity of site, age and/or sex standardization, and quality score on the incidence rates. The various discrete incidence rates will be presented graphically and the impact of various filters on these rates will be inspected using meta-analytic techniques. The use of meta-analysis may help elucidate the epidemiological landscape with respect to the incidence of schizophrenia and aid in the generation of new hypothesis.

A redescription of Homalometron senegalense Fischthal & Thomas, 1972 (Digenea : Apocreadiidae) from Synaptura kleinii (Teleostei) of the western Mediterranean

The apocreadiid digenean Homalometron senegalense is redescribed from the soleid fish Synaptura kleinii from off Corsica in the western Mediterranean. For the first time, lymphatic vessels are described for this species, and the implications of this in the systematics of the Apocreadiidae discussed. This species is considered closest to H. galaicus and H. wrightae, both also reported from soleid hosts. The concept of Apocreadiidae espoused is that most recently developed by Cribb & Bray (1999).

'The utility of human security': Which humans? What security? A reply to Thomas & Tow

Thomas & Tow's evaluation of the utility of human security is an important contribution to an ongoing debate about what security is and for whom security should be provided. In particular, the authors' engagement with the human security agenda is important given the centrality of this approach to recent attempts to rethink security. This article argues, however, that Thomas & Tow's approach to the human security agenda is problematic for two central reasons. First, their attempt to narrow security to make this approach amenable to state policymakers risks reifying the sources of insecurity for individuals everywhere. Second, the conception of human security they put forward appears largely inconsistent with the normative concerns inherent in the human security agenda.

Prediction of mortality in patients without angina: Use of an exercise score and exercise echocardiography

Background Exercise testing has limited efficacy for identifying coronary artery disease (CAD) in the absence of anginal. symptoms. Exercise echocardiography is more accurate than standard exercise testing, but its efficacy in this situation has not been defined. We sought to identify whether the Duke treadmill. score or exercise echocardiography (ExE) could be used to identify risk in patients without anginal symptoms. Methods We studied 1859 patients without typical or atypical angina, heart failure, or a history or ECG evidence of infarction or CAD, who were referred for ExE, of whom 1832 (age 51 15 years, 944 men) were followed for up to 10 years. The presence and extent of ischaemia and scar were interpreted by expert reviewers at the time of the original study. Results Exercise provoked significant (>0.1 mV) ST segment depression in 215 patients (12%), and wall motion abnormalities in 137 (8%). Seventy-eight patients (4%) died before revascularization, only 17 from known cardiac causes. The independent predictors of death were age (RR 1.1, p
