    Notes: 9α-Hydroxylation of 4-androstene-3,17-dione (AD) and 1,4-androstadiene-3,17-dione (ADD) is catalysed by 3-ketosteroid 9α-hydroxylase (KSH), a key enzyme in microbial steroid catabolism. Very limited knowledge is presently available on the KSH enzyme. Here, we report for the first time the identification and molecular characterization of genes encoding KSH activity. The kshA and kshB genes, encoding KSH in Rhodococcus erythropolis strain SQ1, were cloned by functional complementation of mutant strains blocked in AD(D) 9α-hydroxylation. Analysis of the deduced amino acid sequences of kshA and kshB showed that they contain domains typically conserved in class IA terminal oxygenases and class IA oxygenase reductases respectively. By definition, class IA oxygenases are made up of two components, thus classifying the KSH enzyme system in R. erythropolis strain SQ1 as a two-component class IA monooxygenase composed of KshA and KshB. Unmarked in frame gene deletion mutants of parent strain R. erythropolis SQ1, designated strains RG2 (kshA mutant) and RG4 (kshB mutant), were unable to grow on steroid substrates AD(D), whereas growth on 9α-hydroxy-4-androstene-3,17-dione (9OHAD) was not affected. Incubation of these mutant strains with AD resulted in the accumulation of ADD (30–50% conversion), confirming the involvement of KshA and KshB in AD(D) 9α-hydroxylation. Strain RG4 was also impaired in sterol degradation, suggesting a dual role for KshB in both sterol and steroid degradation.

    Notes: In the domain of supply chain management or logistics, there exists a large gap between the needs of companies and the wealth of available best practices. To remedy this situation, we have built a causal model. This causal model relates the use of best practices to the resulting performances, grouped under four main objectives: flexibility, reaction time, quality and cost. Furthermore, based on this model, a logistic audit has been developed to provide a systematic review of logistic performance. It allows companies to obtain an idea about their rate of use of best practices, and their effectiveness based on the key metrics. Because the best practice audit uses a scoring system, it is possible to compare different companies and thus construct a benchmarking database. As in any benchmarking scheme, any gaps give important indications where to improve. The novel idea is the causal model, which indicates which best practices are most likely to improve the specific lagging metrics.

    Notes: Investigates the effectiveness of on-the-job training (OJT). Presents a definition of OJT used for this research project which involved two studies: the first in the call centres of a large company, and the second in post offices. Gives the results of the study which indicate the OJT programs were only partially successful in realising training goals. Indicates that self-efficacy, prior experience with tasks, managerial support and workload were the most powerful predictors for training effectiveness. Concludes that the evidence suggests that OJT is not entirely an effective training method although more research is needed in this area.

    Notes: Foliar and root symptoms are described for Australian lucerne yellows (ALuY), a disease common in Australian lucerne seed crops. A phytoplasma was detected in plants exhibiting symptoms, but not in symptomless lucerne plants. Oligonucleotide primers specific to the phytoplasma 16S-23S rRNA intergenic spacer region (SR) were used in polymerase chain reaction (PCR) assays on DNA extracted from lucerne plants with and without symptoms. Identical restriction fragment length polymorphism (RFLP) enzyme profiles were obtained for PCR products amplified from 10 yellows-affected lucerne samples. RFLP profiles obtained for four restriction enzymes were different from those of the tomato big bud (TBB) phytoplasma. ALuY phytoplasma PCR products were sequenced to determine phylogeny and were found to fall within the faba bean phyllody phytoplasma group, or phytoplasma group 16srII. Transmission electron microscopy revealed phytoplasmas in the phloem of yellows-affected plant samples, but not in symptomless plant samples. Fungal, bacterial and viral agents in the aetiology of Australian lucerne yellows were ruled out.

    Notes: The utilization of organosulphur compounds as sources of sulphur by Escherichia coli is strongly repressed by sulphate. To search for the signal enabling E. coli to alternate gene expression according to the sulphur source, we investigated the transcriptional control of the ssuEADCB operon, required for the transport and desulphonation of aliphatic sulphonates. We demonstrate that, of the two LysR-type regulators involved in expression from the ssu promoter, Cbl acts as a direct and sufficient activator of transcription in vivo and in vitro, whereas CysB downregulates the promoter efficiency. Most importantly, the Cbl-mediated transcription initiation at the ssu promoter in vitro is abolished in the presence of an early metabolite of the sulphate assimilatory pathway, adenosine 5′-phosphosulphate (APS). This role for APS was confirmed in vivo by measuring the expression of β-galactosidase from a transcriptional ssu–lacZ fusion in strains containing different mutations blocking the synthesis and consumption of APS. Our data comprise the first evidence that APS may act as the negative cofactor of the transcriptional regulator Cbl, and that APS, and not sulphate itself, serves as the signalling molecule for sulphate excess.

    Notes: Abstract Total knee replacement is a successful procedure with high clinical success rates. Problems are mostly initiated on the tibial side, and may be due to – amongst others – improper mechanical design of the tibial base plate. In this paper some new design concepts for the tibial component of a total knee prosthesis are presented. They are evaluated experimentally using a model for a proximal tibia, and strain gauge measurements and displacement measurements as experimental techniques. The designs are meant to yield a physiological load sharing between the trabecular and the cortical bone in the proximal tibia, and to minimize anterior lift-off of the tibial base plate. The optimal design required a metal backing of the plastic part and a thin continuous metallic rim in contact with the proximal tibial cortex. An optimal macro-composite structure within the plastic part was obtained by using thin steel wires in the transversal direction, connected to the metallic rim. With this optimal design, it was shown that the force required to close the anterior gap at simulated knee bending was smaller than 250 N, which can easily be applied clinically by an anteriorly placed clamp or bone screw.

    Notes: Describes anti-money laundering statutes within the US federal criminal code. Introduces the USA's Bank Secrecy Act (BSA), a record-keeping and reporting statute that also requires financial institutions to implement comprehensive anti-money laundering programmes; its enforcement authority is generally exercised through the Financial Crime Enforcement Network (FinCEN). Outlines the bank regulatory authority, administrative sanctions, civil money penalties, and the "death penalty", which is termination of a national bank's franchise. Discusses recent enforcement actions by FinCEN, the Department of Justice, and Federal banking agencies. Concludes that the apparent trend towards more substantial fines and other sanctions for BSA violations will probably accelerate for various reasons.
