Abstract
The influenza season 2008-9 started in week 49 of 2008 and is so far characterised by influenza virus type A subtype H3N2. Isolates of this subtype that were tested proved susceptible to neuraminidase inhibitors, but resistant to M2 inhibitors. The circulating A(H3N2) viruses are antigenically similar to the component in the current northern hemisphere influenza vaccine.

Abstract
Re-analysis of the influenza pandemic of 1918 has given reassurance about a rather low reproductive number (R(o)), a prolonged herald wave of virus and that the skewed mortality towards the young adult could be a singularly unique event dependent upon previous infection history, perhaps not to be repeated in a future pandemic. Over 99% of those who contracted the virus survived, in spite of the absence of antivirals, vaccine and antibiotics for the secondary bacteria infections which probably accounted for one-third of the 50 million deaths. Therefore, in spite of a three-fold population increase since 1918 and 100 thousand plane journeys daily, judicious and careful planning together with a stockpile of antiviral drugs, oseltamivir, zanamivir and M2 blockers and a generic H5N1 vaccine, and application of hygiene would be expected to reduce mortality in a new pandemic, to figures significantly less than 1918.

Abstract
The Great Influenza Pandemic of 1918-1919 was a cataclysmic outbreak of infection wherein over 50 million people died worldwide within 18 months. The question of the origin is important because most influenza surveillance at present is focussed on S.E. Asia. Two later pandemic viruses in 1957 and 1968 arose in this region. However we present evidence that early outbreaks of a new disease with rapid onset and spreadability, high mortality in young soldiers in the British base camp at Etaples in Northern France in the winter of 1917 is, at least to date, the most likely focus of origin of the pandemic. Pathologists working at Etaples and Aldershot barracks later agreed that these early outbreaks in army camps were the same disease as the infection wave of influenza in 1918. The Etaples camp had the necessary mixture of factors for emergence of pandemic influenza including overcrowding (with 100,000 soldiers daily changing), live pigs, and nearby live geese, duck and chicken markets, horses and an additional factor 24 gases (some of them mutagenic) used in large 100 ton quantities to contaminate soldiers and the landscape. The final trigger for the ensuing pandemic was the return of millions of soldiers to their homelands around the entire world in the autumn of 1918.

Abstract
Quorum sensing (QS) in Gram-negative bacteria is generally assumed to be mediated by N-acyl-homoserine lactone molecules while Gram-positive bacteria make use of signaling peptides. We analyzed the occurrence in Gram-negative bacteria of peptides and transporters that are involved in quorum sensing in Gram-positive bacteria. Many class II bacteriocins and inducing factors produced by lactic acid bacteria (LAB) and competence stimulating peptides (CSPs) synthesized by streptococci are processed by their cognate ABC-transporters during their secretion. During transport, a conserved leader sequence, termed the double-glycine motif (GG-motif), is cleaved off by the N-terminal domain of the transporter, which belongs to the Peptidase C39 protein family. Several peptides containing a GG-motif were recently described in Gram-negative bacteria (Trends Microbiol 2001;9:164-8). To screen for additional putative GG-motif containing peptides, an in silico strategy based on MEME, HMMER2.2 and Wise2 was designed. Using a curated training set, a motif model of the leader peptide was built and used to screen over 120 fully sequenced bacterial genomes. The screening methodology was applied at the nucleotide level as probably many small peptide genes have not been annotated and may be absent from the non-redundant databases. It was found that 33% of the screened genomes of Gram-negative bacteria contained one or more transporters carrying a Peptidase C39 domain, compared to 44% of the genomes of Gram-positive bacteria. The transporters can be subdivided into four classes on the basis of their domain organization. Genes coding for putative peptides containing 23-142 amino acids and a GG-motif were found in close association with genes coding for Peptidase C39 domain containing proteins. These peptides show structural similarity to bacteriocins and peptide pheromones of Gram-positive bacteria. The possibility of signal transduction based on peptide signaling in Gram-negative bacteria is discussed.

Abstract
An analysis of the geochemical distribution of selected trace metals among various geochemical phases of the sediments in the Tees estuary was carried out using a sequential extraction technique and Differential Stripping Voltammetry. The sediments of the estuary are mainly organic rich clay silts and metal concentrations exceed those in the water column. Speciation results show that contamination of the estuary is mainly from anthropogenic sources. Pb and Zn are associated with the reducible, residual and oxidisable fractions. The speciation pattern of Cd was similar to those of lead and zinc. However there were also some exchangeable and bound to carbonate fractions although these were less significant. Cu is largely associated with the oxidisable and residual fractions, with insignificant bound to carbonate, exchangeable and reducible fractions. The most bioavailable forms of the metals are the free inorganic ions. Total metal concentrations in the estuary display a downward trend since the 1970s.

Abstract
Research on the regulation of gene expression in human germ cells and preimplantation embryos is restricted due to the scarcity of samples and the requirement for highly sensitive molecular techniques to investigate the few cells available. To overcome these difficulties, we have developed a reliable procedure capable of generating amplified cDNA preparations from single cells. Using this procedure, we prepared cDNA from primordial germ cells (PGCs) isolated from the gonads of fetuses at 10 weeks gestation and from preimplantation embryos at the 1-cell, 4-cell, 8-cell and blastocyst stages. Our cDNA preparations allow us to investigate the expression profile of an almost unlimited number of different genes in the same sample preparation. This is of great advantage for studies of a panel of genes in a particular family or functional group, or with related mechanisms of regulation, e.g., developmental genes, oncogenes, cell cycle-control genes and imprinted genes. We have used these cDNA preparations in conjunction with differential display to identify genes specifically expressed in PGCs and preimplantation embryos in a sex- and developmental stage-specific manner. Genes specifically expressed in PGCs, oocytes and embryos were further analysed for their expression in embryonal carcinoma cells and in their differentiated derivatives following treatment by retinoic acid. Our strategy will disclose genes essential for gametogenesis and embryonic development which may only be expressed at certain stages of their development. The germ cell- and embryo-specific cDNA molecules, cDNA libraries and microarrays are a valuable resource for other researchers in this field.

Abstract
The efficiency of animal production using cloning technology is still relatively low and research to determine a more efficient nuclear transfer procedure is ongoing. One approach which may be informative in assessing the viability of nuclear transfer embryos is the analysis of embryonic gene expression. Using RT-PCR techniques we have previously detected the aberrant expression of FGF4, FGFr2 and IL6 in a significant proportion of bovine granulosa cell-derived nuclear transfer embryos, which correlated with a limited developmental potential in vivo. In order to analyse the effect of different donor cell nuclei on embryonic gene expression we have now analysed the expression of these genes in nuclear transfer embryos reconstructed with fetal epithelial cell nuclei. In addition, we have compared the expression of these genes in bovine nuclear transfer embryos produced by cell fusion or direct injection with variations in the timing of oocyte activation. In all nuclear transfer embryos analysed, FGFr2 and IL6 transcripts were detected at a similar rate to that in IVF embryos. However, the absence of FGF4 transcripts was again evident in a large proportion of nuclear transfer embryos and most significantly in those embryos whose development was activated almost immediately following the transfer of the donor nucleus. The results demonstrate the effects that different donor cell lines and different nuclear transfer procedures may have on the expression of developmentally important genes in nuclear transfer embryos.

Abstract
The state of Louisiana Medical Education Commission offers the second publication in the Journal of Louisiana State Medical Society on Graduate Medical Education (GME) in Louisiana. The four previous annual reports of the Commission have provided data to focus on trends in size, status, proportions, and issues on GME. The Commission was established by Act 3 of the 1997 Louisiana Legislature. This summary report for 2001 provides the detailed and updated data on all GME residents and fellows in Louisiana for the last academic year. The presentation of data and trends poses three questions for analysis. First, what are the trends in Graduate Medical Education in Louisiana for total residents and fellows? Second, how do these trends relate to the size, status, and proportions of Graduate Medical Education in Louisiana and as compared to the United States? Third, where do these trends lead to the future in predictions and recommendations for Graduate Medical Education in Louisiana? The 4-year trend in the total number of Graduate Medical Education filled positions has been relatively consistent, with some recent increases in primary care residency positions, especially in Family Medicine and Medicine/Pediatrics. These increases will plateau as current trends on new program formation stabilize, requiring emphasis on recruitment and factors promoting recruitment for GME in the state of Louisiana. The state of Louisiana has participated proportionately relative to population in the growth of medical education in the last century and compares favorably with other states and the nation. Louisiana has exceeded national averages in the increases in primary care programs and residents and in the retention of trainees in practice sites in the state.

Abstract
PURPOSE In a porcine model we evaluated the efficacy of the absorbable fibrin adhesive bandage and other novel fibrin products for treating major renal stab wounds. MATERIALS AND METHODS In commercial swine we produced an almost lethal, grade 4 renal stab wound via a 3.5 cm. sagittal, centrally located, through-and-through laceration. Each pig then received treatment in random fashion, including conventional oversewing of capsular defects with absorbable gelatin sponge and horizontal mattress sutures in 6, external absorbable fibrin adhesive bandage that was pressure held for 60 seconds in 6, external and internal absorbable fibrin adhesive bandage that was applied externally, inserted into the renal defect and pressure held for 60 seconds in 6, liquid fibrin sealant that was placed in the laceration and held for 60 seconds in 8, fibrin foam that was applied in the same manner as liquid fibrin in 5 and closing of the peritoneum over the lacerated kidney without further treatment in 6. Blood loss and time to hemostasis were recorded. Animals were sacrificed at 6 weeks to evaluate the injured renal unit. RESULTS Compared with conventional therapy the absorbable fibrin adhesive bandage applied externally alone or externally and internally resulted in significantly less bleeding and significantly less time to hemostasis (p <0.001). Liquid fibrin and fibrin foam did not reliably achieve hemostasis. Postoperatively computerized tomography and histological sectioning suggested that the absorbable fibrin adhesive bandage results in a stable, durable clot and healing is at least as successful as with conventional treatment. CONCLUSIONS The absorbable fibrin adhesive bandage appears to be a safe, rapid means of renal salvage after injury.

Abstract
In a field trial, oiled beach sand was buried in a coastal dune system in south Wales. A monitoring programme was designed to assess the rate of leaching of inorganic ions and hydrocarbons from the deposit. Active breakdown of the weathered oil occurred within the oiled beach sand, but hydrocarbons from the original material, or arising as a result of degradation, did not follow the same leaching pattern as inorganic ions; they remained within the original deposit. The results suggest that weathered oil coming ashore from spills at sea can be mixed with sand and buried to degrade in coastal soils, without risk of groundwater contamination by hydrocarbons.
