Abstract
Aspects of husbandry, productivity parameters, diseases, marketing and farmer attitudes in small-scale broiler farms in Botswana were studied using a questionnaire-based survey. The number of broilers per production cycle in small-scale operations ranged from 100 to 2000, with an average of 640. On average, small-scale producers had 4-5 production cycles per annum with an interval of 2-3 weeks between batches. The average marketing age was 48.3 days at a live weight of 1.79 kg and a carcase weight of 1.42 kg. The average feed conversion ratio was estimated to be 2.72 (kg feed/kg live weight) and the average mortality was 9.15%. Overall, the performance indices of broilers under small-scale farm conditions were much poorer than those obtained elsewhere under improved management conditions, but these lower performance levels are suggestive of the potential that exists for further improvement. The survey also identified several areas of concern that constrain the realization of the full potential of this sector. Factors contributing to the poor performance under small-scale farm conditions are complex, but feed supply and quality, chick quality and farmer training appear to be areas for immediate improvement.

Abstract
PURPOSE We determined the maximum-tolerated dose (MTD) and the dose-limiting toxicities (DLT) of 17-allylamino-17-demethoxygeldanamycin (17-AAG) when infused on days 1, 8, and 15 of a 28-day cycle in advanced solid tumor patients. We also characterized the pharmacokinetics of 17-AAG, its effect on chaperone and client proteins, and whether cytochrome P450 (CYP) 3A5 and NAD(P)H:quinone oxidoreductase 1 (NQO1) polymorphisms affected 17-AAG disposition or toxicity. PATIENTS AND METHODS An accelerated titration design was used. Biomarkers were measured in peripheral-blood mononuclear cells (PBMCs) at baseline and on days 1 and 15, and pharmacokinetic analysis was performed on day 1 of cycle 1. CYP3A5*3 and NQO1*2 genotypes were determined and correlated with pharmacokinetics and toxicity. RESULTS Twenty-one patients received 52 courses at 11 dose levels. DLTs at 431 mg/m(2) were grade 3 bilirubin (n = 1), AST (n = 1), anemia (n = 1), nausea (n = 1), vomiting (n = 1), and myalgias (n = 1). No tumor responses were seen. 17-AAG consistently increased heat shock protein (Hsp) 70 levels in PBMCs. At the MTD, the clearance and half-life (t(1/2)) of 17-AAG were 11.6 L/h/m(2) and 4.15 hours, respectively; whereas the active metabolite 17-aminogeldanamycin had a t(1/2) of 7.63 hours. The CYP3A5*3 and NQO1*2 polymorphisms were not associated with 17-AAG toxicity. The CYP3A5*3 polymorphism was associated with higher 17-AAG clearance. CONCLUSION The MTD of weekly 17-AAG is 308 mg/m(2). 17-AAG induced Hsp70 in PBMCs, indicating that Hsp90 has been affected. Further evaluation of 17-AAG is ongoing using a twice-weekly regimen, and this schedule of 17-AAG is being tested in combination with chemotherapy.

Abstract
The growing number of trials that have highlighted the benefit of intensive lowering of total- and low density lipoprotein (LDL)-cholesterol levels especially with statins has created a need for more efficacious agents. Pitavastatin is a new synthetic 3-hydroxy-3-methyl glutaryl coenzyme A reductase inhibitor, which was developed, and has been available in Japan since July 2003. Metabolism of pitavastatin by the cytochrome P450 (CYP) system is minimal, principally through CYP 2C9, with little involvement of the CYP 3A4 isoenzyme, potentially reducing the risk of drug-drug interactions between pitavastatin and other drugs known to inhibit CYP enzymes. To date, human and animal studies have shown pitavastatin to be potentially as effective in lowering LDL-cholesterol levels as rosuvastatin; although, head-to-head studies are yet to be conducted.

Abstract
Few data are available on the effects of high dose statin therapy on lipoprotein subfractions in type 2 diabetes. In a double blind randomised placebo-controlled trial we have studied the effects of 80 mg atorvastatin over 8 weeks on LDL, VLDL and HDL subfractions in 40 overweight type 2 diabetes patients. VLDL and LDL subfractions were prepared by density gradient ultracentrifugation. Triglycerides, cholesterol, total protein and phospholipids were measured and mass of subfractions calculated. HDL subfractions were prepared by precipitation. Atorvastatin 80 mg produced significant falls in LDL subfractions (LDL(1) 66.2 mg/dl:36.6 mg/dl, LDL(2) 118:56.6 mg/dl, LDL(3) 36.9:19.9 mg/dl all P < 0.01 relative to placebo) and VLDL subfractions (VLDL(1) 55:22.1 mg/dl, VLDL(2) 40.1:19.1 mg/dl, VLDL(3) 52.6:30 mg/dl all P < 0.01 relative to placebo). There was no change in the proportion of LDL present as LDL(3). There was a reduction in the proportion of VLDL as VLDL(1) and a reciprocal increase in the proportion as VLDL(3). Changes in VLDL subfractions were associated with changes in lipid composition, particularly a reduction in cholesterol ester and a reduction in the cholesterol ester/triglyceride ratio. Effects on HDL subfractions were largely neutral. High dose atorvastatin produces favourable effects on lipoprotein subfractions in type 2 diabetes which may enhance antiatherogenic potential.

Abstract
BACKGROUND Cleft lip and cleft palate are common birth defects, affecting about one baby of every 700 born. Feeding these babies is an immediate concern and there is evidence of delay in growth of children with a cleft as compared to those without clefting. In an effort to combat reduced weight for height, a variety of advice and devices are recommended to aid feeding of babies with clefts. OBJECTIVES This review aims to assess the effects of these feeding interventions in babies with cleft lip and/or palate on growth, development and parental satisfaction. SEARCH STRATEGY We searched the Cochrane Oral Health Group's Trials register (June 2001), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 2, 2004), MEDLINE (1966 to May 24th 2004), EMBASE (1980 to August 7th 2002), CINAHL (1982 to August 7th 2002), PsychINFO (1967 to August 13th 2002), AMED (1985 to August 13th 2002). Attempts were made to identify both unpublished and ongoing studies. There was no restriction with regard to language of publication. SELECTION CRITERIA Studies were included if they were randomised controlled trials (RCTs) of feeding interventions for babies born with cleft lip, cleft palate or cleft lip and palate up to the age of 6 months (from term). DATA COLLECTION AND ANALYSIS Studies were assessed for relevance independently and in duplicate. All studies meeting the inclusion criteria were data extracted and assessed for validity independently by each member of the review team. Authors were contacted for clarification or missing information whenever possible. MAIN RESULTS Four RCTs with a total of 232 babies, were included in the review. Comparisons made within the RCTs were squeezable versus rigid feeding bottles (two studies), breastfeeding versus spoon-feeding (one study) and maxillary plate versus no plate (one study). No statistically significant differences were shown for any of the primary outcomes when comparing bottle types, although squeezable bottles were less likely to require modification. No statistically significant difference was shown for infants fitted with a maxillary plate compared to no plate. A statistically significant difference in weight (kg) at 6 weeks post-surgery was shown in favour of breastfeeding when compared to spoon-feeding (mean difference 0.47; 95% CI: 0.20, 0.74). REVIEWERS' CONCLUSIONS Squeezable bottles appear easier to use than rigid feeding bottles for babies born with clefts of the lip and/or palate, however, there is no evidence of a difference in growth outcomes between the bottle types. There is weak evidence that babies should be breastfed rather than spoon-fed following surgery for cleft lip. No evidence was found to assess the use of any types of maternal advice and/or support for these babies.

Abstract
The AR (androgen receptor) belongs to the nuclear receptor superfamily and directly regulates patterns of gene expression in response to the steroids testosterone and dihydrotestosterone. Sequences within the large N-terminal domain of the receptor have been shown to be important for transactivation and protein–protein interactions; however, little is known about the structure and folding of this region. Folding of the AR transactivation domain was observed in the presence of the helix-stabilizing solvent trifluorethanol and the natural osmolyte TMAO (trimethylamine N-oxide). TMAO resulted in the movement of two tryptophan residues to a less solvent-exposed environment and the formation of a protease-resistant conformation. Critically, binding to a target protein, the RAP74 subunit of the general transcription factor TFIIF, resulted in a similar resistance to protease digestion, consistent with induced folding of the receptor transactivation domain. Our current hypothesis is that the folding of the transactivation domain in response to specific protein–protein interactions creates a platform for subsequent interactions, resulting in the formation of a competent transcriptional activation complex.

Abstract
AIM Incidental aortic valve calcification is often detected during computed tomography. The aim was to compare the severity of valvular stenosis and calcification in patients with aortic stenosis. MATERIALS AND METHODS One hundred and fifty-seven patients aged 68+/-11 years (range: 34-85) with aortic valve stenosis underwent multislice helical computed tomography and Doppler echocardiography performed by independent, blinded observers. The aortic valve calcium score was determined using automated computer software calibrated with a phantom. RESULTS Doppler echocardiography demonstrated a post-valve velocity of 3.45+/-0.66 m/s and a peak gradient of 49+/-11 mmHg. Computed tomography showed excellent reproducibility and the median aortic valve calcium score was 5858 AU (interquartile range, 1555-14,596). The computed tomography aortic valve calcium score positively correlated with the Doppler post-valve velocity and peak gradient (r=0.54, p<0.0001 for both) of the aortic valve. All patients with severe aortic stenosis had a calcium score of >3700 AU. CONCLUSION Calcification of the aortic valve is closely associated with the severity of aortic stenosis, and heavy calcification suggests the presence of severe aortic stenosis that requires urgent cardiological assessment. Patients with lesser degrees of aortic valve calcification should be screened for aortic stenosis and monitored for disease progression.

Abstract
Silicon stabilized tricalcium phosphate [Si-TCP] is formed within the calcium hydroxyapatite (HA)-tricalcium phosphate (TCP) system when a stoichiometric precipitate of hydroxyapatite is fired at 1,000 degrees in the presence of SiO(2). This paper proposes a composition range and crystallographic structure for Si-TCP. Reitveld XRD powder diffraction, transmission electron microscopy, infrared and proton nuclear magnetic resonance measurements show that crystalline Si-TCP is associated with the displacement of OH from an initial hydroxyapatite structure. The resulting calcium phosphate is modified by the incorporation of silicon into its structure with excess silica contributing to an amorphous component. Si-TCP has a monoclinic structure with a space group P2(1)/a akin to alpha-TCP with estimated lattice constants of a=12.863+/-0.004 A, b=9.119 +/-0.003 A, c=15.232+/-0.004 A, beta=126.3+/-0.1 degrees. It is proposed that Si(4+) substitutes for P(5+)in the TCP lattice with the average chemical composition of Si-TCP set primarily by the mechanisms available for charge compensation. While the formation of OH vacancies in HA initiates the transformation to Si-TCP, two mechanisms of charge compensation in the Si-TCP structure are plausible. If O(2-) vacancies provide charge compensation, the composition of Si-TCP is Ca(3)(P(0.9)Si(0.1)O(3.95))(2) derived for the addition of 0.33 mol SiO(2):mol HA. If excess Ca(2+) compensates, the composition is Ca(3.08)(P(0.92)Si(0.08)O(4))(2) derived for the addition of 0.25 mol SiO(2):mol HA. The reaction occurs most effectively when SiO(2) is added as a colloidal suspension rather than by the in-situ thermal decomposition of a silicon metallorganic compound. The material is a bioceramic of major biological interest because of its osteoconductivity and unique influence on skeletal tissue repair and remodeling.

Abstract
Sampling of beetles, beetle galleries, and stained tree tissues by ourselves and others to obtain isolates of ophiostomatoid fungal species yielded three Ceratocystiopsis-like entities. Using partial rDNA sequences, these were previously identified as being different from both each other and all other described species of Ceratocystiopsis and Ophiostoma. As Ceratocystiopsis Upadhyay et Kendrick has been reduced to synonymy with Ophiostoma Syd. et P. Syd., and sufficient dried material is now available, these are described herein as Ophiostoma carpenteri sp. nov., Ophiostoma rollhansenianum sp. nov., and Ophiostoma manitobense sp. nov. We found O. carpenteri to be closely related to Ophiostoma retusum (R.W. Davidson et T.E. Hinds) Hausner et al., and that both species may actually be fungal symbionts and could represent a discrete genus. Although morphologically O. rollhansenianum appears similar to Ophiostoma minutum Siemaszko, a clearly variable species, and O. manitobense to Ophiostoma minus (Hedgc.) Syd. et P. Syd., earlier rDNA data indicate that O. rollhansenianum and O. manitobense are actually more closely related to Ophiostoma coliferum (Marmolejo et Butin) Hausner et al., and Ophiostoma ranaculosum (J.R. Bridges et T.J. Perry) Hausner et al. We also comment on some morphological features that have previously been overlooked or misreported in Cornuvesica falcata (E.F. Wright et Cain) C.D. Viljoen et al., such as the ascospores actually being hyaline and the presence of two distinct Chalara anamorphs.Key words: Ophiostoma, molecular and morphological criteria, Ceratocystiopsis, Cornuvesica.

Abstract
Only a small proportion of the mouse genome is transcribed into mature messenger RNA transcripts. There is an international collaborative effort to identify all full-length mRNA transcripts from the mouse, and to ensure that each is represented in a physical collection of clones. Here we report the manual annotation of 60,770 full-length mouse complementary DNA sequences. These are clustered into 33,409 'transcriptional units', contributing 90.1% of a newly established mouse transcriptome database. Of these transcriptional units, 4,258 are new protein-coding and 11,665 are new non-coding messages, indicating that non-coding RNA is a major component of the transcriptome. 41% of all transcriptional units showed evidence of alternative splicing. In protein-coding transcripts, 79% of splice variations altered the protein product. Whole-transcriptome analyses resulted in the identification of 2,431 sense-antisense pairs. The present work, completely supported by physical clones, provides the most comprehensive survey of a mammalian transcriptome so far, and is a valuable resource for functional genomics.

Abstract
The aim of this study was to investigate whether femoral artery pulsatility index (PI) can be used as an indicator of vasomotor tone in the digit of an ungulate species by measuring the change in PI induced by infusion of vasoactive agents in halothane-anaesthetised sheep. Intra-arterial infusion of the vasoconstrictor phenylephrine (9 microg min(-1)) tended to increase waveform PI (3.89-6.24, n=4, P=0.100). Infusion of a low dose (3 microg min(-1)) of the vasodilator sodium nitroprusside did not alter femoral artery PI, however infusion of a higher dose (30 microg min(-1)) tended to increase PI (5.39-6.70, n=5, P=0.059). During these studies heart rate, mean ABP and p(a)CO(2) did not change significantly. The tendency for PI to increase in response to vasodilation was unexpected and the mechanism involved is unclear. It appears that femoral artery PI cannot be used to predict vasomotor tone in the digit of the anaesthetised sheep.

Abstract
Following an increase in average waiting times associated with a child health service in East London, an initiative to rapidly reduce the numbers of children waiting long periods following a referral was undertaken over the period May to June 1999. A multidisciplinary cooperative approach was adopted operating within the existing available resources and involved medical, nursing, managerial and administrative staff. The initiative involved a review of the accuracy of the waiting list, followed by an invitation to remaining patients to provide an option of continuing to wait to be seen or offering attendance at a rapid response clinic associated with reduced waiting and consultation times. Half-hourly appointments were routinely offered instead of hourly appointments and proformas were adopted for history taking and onward referrals to save time spent on administration. A total of 162 patients were seen over the course of a month and a satisfaction questionnaire completed by relatives indicated a preference for the new service. The mean waiting time was reduced to under a quarter of the time at the start of the initiative to a mean of less than two months. The purpose of the study was to see if the waiting list could be reduced by using existing staff. We wanted to ascertain the parents' views whether shorter waits and shorter consultation periods were acceptable, and to ascertain if the waiting list could be kept down or whether the waiting list would rapidly recur after the rapid response clinics stopped. The findings are discussed in relation to initiatives elsewhere and the need to maintain a high quality service.

Abstract
A metabolic study of the effects of space flight on various chemical elements, particularly those with special relevance to the musculo-skeletal system, was carried out on the nine astronauts who participated in the three Skylab flights of 28, 59 and 84 days in 1973-1974. The study required of the cooperating crewmen constant dietary intake, continuous 24-hour urine collections and total fecal collections for 21-31 days before each flight, throughout each flight and for 17-18 days post-flight. Increases in urinary calcium and negative calcium balances during space flight were generally similar to those found in previous immobilization and bedrest studies. The persistence of these alterations in calcium metabolism throughout the flights suggested that calcium losses would continue in weightlessness for a very long time. Significant losses of nitrogen and phosphorus occurred, associated with observed reduction in muscle tissue. Both mineral and muscle losses occurred despite vigorous exercise regimens in flight. It was concluded that unless protective measures can be developed, capable musculo-skeletal function is likely to be impaired in space flights, ultimately to be conducted to Mars, of 11/2 to 3 years duration.

Abstract
Anti-double-stranded DNA (anti-dsDNA) is arguably one of the most specific autoantibodies in systemic lupus erythematosus (SLE). This antibody is associated with more severe SLE and with glomerulonephritis. From 196 pedigrees multiplex for SLE, we selected those that had any SLE affected positive for anti-dsDNA by the Crithidia luciliae kinetoplast imunofluorescence assay. This stratification strategy tested the hypothesis that anti-dsDNA would identify a more genetically homogeneous group of pedigrees, in which previously undetected linkage effects could be established. A genome screen data for linkage to SLE was available at 307 microsatellite markers for this selected group of 71 pedigrees: 37 European-American, 29 African-American, and five others. The most significant results were obtained at 19p13.2 (LOD(max) = 4.93), named SLED1, in the 37 European-American pedigrees using a dominant model with mixed penetrances (92% for females and 49% for males) at 100% homogeneity (theta = 0). A second linkage effect, SLED2, was established in the 29 African-American pedigrees at 18q21.1 (LOD(max) = 3.40) using a recessive model with 100% penetrance (theta = 0.1). Parametric and non-parametric multipoint analyses were performed, which provided further evidence and support of susceptibility genes residing in these regions. In conclusion, two powerful linkages have been detected with SLE based on the presence of anti-dsDNA. These findings show SLE to be a richly complicated disease phenotype that is now ripe for important new discovery through a genetic approach.

Abstract
AIMS To describe the laboratory confirmation of meningococcal disease, using culture and non-culture based techniques, between 1993 and 1999 as part of a national service in Scotland. METHODS Samples from patients with suspected meningococcal disease in Scotland were analysed by culture and non-culture based techniques to gain a laboratory confirmation of disease. Data were analysed to establish the number of disease cases, the serogroups of the organisms involved, and the importance of the techniques used. RESULTS Between 1993 and 1999, there was a total of 1749 notified cases of meningococcal disease in Scotland. Culture based methods provided a laboratory confirmation of 788 cases whereas non-culture techniques confirmed 461 cases. CONCLUSIONS Non-culture techniques were a useful addition to culture based techniques in Scotland and improved the dataset required for public health management, disease surveillance, and vaccine policy.

Abstract
External quality control of hepatitis B virus (HBV) DNA detection remains an important issue. This study reports and compares the results obtained from two different proficiency panels for both the qualitative and quantitative assessment of HBV DNA. The panels were designed by the European Union Quality Control Concerted Action, prepared by Boston Biomedica, Inc., and distributed in May 1999 (panel 1) and February 2000 (panel 2). Each contained two negative samples and six positive samples with 10(3) to 10(7) copies/ml (panel 1) or 10(3) to 2 x 10(6) copies of HBV DNA per ml (panel 2). For panel 1, 42 laboratories submitted 20 qualitative (all in-house PCRs) and 37 quantitative (87% commercial assays) data sets. For panel 2, 51 laboratories submitted 25 qualitative (all in-house PCRs) and 47 quantitative (94% commercial assays) data sets. Five data sets (8.8%) in panel 1 and two data sets (2.8%) in panel 2 contained totals of six and two false-positives, respectively, corresponding to false-positive result rates of 5.3% for panel 1 and 1.4% for panel 2. The false-negative result rates of 10.5% for panel 1 and 17.4% for panel 2 were dependent on the detection levels of the assays employed as well as panel composition. In the qualitative analysis of all data sets, 47.4% (panel 1) and 51.4% (panel 2) had all samples correct. An adequate or better score (all correct or only the weak-positive sample missed) was obtained with 77.2% of the panel 1 samples and 68.1% of the panel 2 samples. In the quantitative analysis, 57.1% (panel 1) and 42.6% (panel 2) of the data sets achieved an adequate or better score (positive results within the acceptable range of the geometric mean +/- 0.5 log(10) of all positive results). These results demonstrate that while the qualitative performance of HBV detection has considerably improved compared to that of a previously published HBV proficiency study, the detection levels of many commercial quantitative assays are still too high to allow adequate quantitation of all relevant clinical samples.

Abstract
OBJECTIVE The purpose of this study is to describe and to implement a new fast three-point Dixon MR imaging sequence with online image reconstruction, and to compare this sequence with conventional chemical shift selective (CHESS) suppression of fat in pediatric musculoskeletal imaging. SUBJECTS AND METHODS A three-point Dixon technique using a fast spin-echo sequence with a new phase-correction algorithm providing online image reconstruction was implemented on a 1.5-T scanner. Twelve pediatric patients and young adults were imaged with both the new three-point Dixon and conventional CHESS sequences. Three radiologists un-aware of imaging parameters and clinical information independently scored the homogeneity of fat suppression and conspicuity of abnormality using a four-point system. An additional comparison between the two techniques was made using a phantom. RESULTS The three-point Dixon method showed superior fat suppression and lesion conspicuity (p < 0.001), particularly in the hands and feet, where CHESS is prone to inconsistent fat suppression. The phantom study showed no significant difference in the ratio of suppressed fat signal to background noise and more homogeneous fat suppression using the three-point Dixon method. CONCLUSION Compared with CHESS, the new fast three-point Dixon sequence with online image reconstruction provides superior fat suppression and lesion conspicuity and can be routinely used in pediatric musculoskeletal imaging.

Abstract
The American Medical Informatics Association 2001 Spring Congress brought together the public health and informatics communities to develop a national agenda for public health informatics. Discussions on funding and governance; architecture and infrastructure; standards and vocabulary; research, evaluation, and best practices; privacy, confidentiality, and security; and training and workforce resulted in 74 recommendations with two key themes: (1) all stakeholders need to be engaged in coordinated activities related to public health information architecture, standards, confidentiality, best practices, and research and (2) informatics training is needed throughout the public health workforce. Implementation of this consensus agenda will help promote progress in the application of information technology to improve public health.

Abstract
AIM To determine if the introduction of preformatted patient record charts improved documentation by doctors in a rural emergency department. METHODS All medical records of patients who were discharged from the emergency department were collected and analysed for a period of two weeks (control). The preformatted patient charts were then introduced for a further two weeks, and analysed for the presence or absence of key content items RESULTS After exclusions, 137 control charts and 96 preformatted charts were collected and analysed. It was found that, overall, there was a significant improvement in the number of the key items documented (p<0.005). There was a trend towards improvement in four parameters, but for three other key content items, there was a nonsignificant decline in documentation standards. CONCLUSION A structured proforma does improve documentation. However, the improvement is small and further studies are required before use of preformatted patient records for the undifferentiated emergency department patients can be recommended.

Abstract
Families of 99 children with early-onset conduct problems, aged 4-8 years, were randomly assigned to a child training treatment group (CT) utilizing the Incredible Years Dinosaur Social Skills and Problem Solving Curriculum or a waiting-list control group (CON). Post-treatment CT children had significantly fewer externalizing problems at home, less aggression at school, more prosocial behavior with peers, and more positive conflict management strategies than CON children. Significantly more CT than CON children showed clinically significantly improvements on reports and independent observations of aggressive and noncompliant behavior. The differential treatment response was evaluated according to child comorbidity with attention deficit hyperactivity disorder (ADHD), parenting discipline practices. and family risk factors. The only risk factor related to failure to make improvements in child conduct problems after treatment was negative parenting (i.e., maternal critical statements and physical force). The long-term follow-up 1 year later indicated that most of the significant post-treatment changes were maintained.

Abstract
The meningococcus is an important cause of morbidity and mortality and a rapid laboratory diagnosis is required through accurate, non-culture-based methods. Body fluids that are easily obtainable are preferred for this route of diagnosis and urine is the specimen of choice as it can be obtained non-invasively. Urine samples were tested from patients with suspected meningococcal disease and tested by latex agglutination and PCR. It was shown that urinary PCR is not useful for the laboratory confirmation of MD but latex agglutination testing may be useful in certain settings prior to confirmatory testing by a reference laboratory.

Abstract
A composite scale for assessing pain in dogs in a hospital setting has been developed on the basis of observations of their behaviour. Initially, 279 words and expressions suggested by 69 veterinary surgeons were reduced into 47 words and expressions which were allocated into seven behaviour categories: demeanour and response to people, posture, mobility, activity, response to touch, attention to painful area and vocalisation. Three statistical methods, hierarchical agglomerative cluster analysis, Cronbach's alpha coefficient, and analysis of variance with multiple comparisons and empirical cumulative distributions, were used to validate these procedures, and a questionnaire accompanied by a list of definitions was designed around the expressions. The new composite scale is more detailed than previously reported scales for assessing pain in dogs on the basis of their behaviour, and the methods used in its development are based on sound scientific principles.

Abstract
PURPOSE We developed limited sampling models (LSMs) for predicting the area under the curve (AUC) of irinotecan (CPT-11) and its metabolites SN-38 and SN-38 glucuronide (SN-38G). PATIENTS AND METHODS Regression models were developed based on data from a phase I clinical trial involving 34 patients with advanced solid tumor malignancies who received CPT-11 as a 90-min infusion on an every 3-week dosing schedule. Multiple stepwise regression procedures were supplemented by all possible subsets regression analysis. Alternative clinically based and empirically derived LSMs were determined via model validation assessment including bootstrap simulation testing. RESULTS The best LSMs for CPT-11 AUC included concentrations recorded at the end of infusion and 4 h later with an option to include a blood draw at 7.5 h from infusion start. For SN-38 and SN-38G AUC, optimal LSMs included the additional metabolite concentration at 48 h after infusion. The LSMs were able to predict most patient AUC values to within 10% of the true value. CONCLUSION CPT-11 AUC can be modeled with acceptable accuracy using only two or three plasma concentration time-points. A variety of LSM alternatives provided comparable accuracy in predicting AUC. Given the wide variety of LSM alternatives, clinical considerations and patient burden become more important performance parameters than statistical considerations for the choice of time-points in constructing LSMs.

Abstract
Because the ARRT's mission is to recognize individuals "qualified" in the use of ionizing and nonionizing radiation for medical imaging and radiation therapy, it falls upon the ARRT to define what "qualified" means. The goal of the competency project was to further refine our definition of what qualified means as it relates to educational preparation and to incorporate that refined definition into existing eligibility requirements. Certification requirements should be both specific and public. The competency requirements accomplish this for ARRT's educational eligibility requirements and will help advance certification as well as education in the profession.

Abstract
We observed highly aggressively proliferating immortalized (HAPI) cells growing in cultures that had been enriched for microglia. The cells were initially obtained from mixed glial cultures prepared from 3-day-old rat brains. HAPI cells are typically round with few or no processes when cultured in 10% serum containing medium. As the percentage of serum in the medium is decreased, the HAPI cells have more processes. HAPI cells stain for the isolectin B4, OX-42, and GLUT5, which are markers for microglial cells, but the cells do not immunolabel with A2B5, a marker of cells in the oligodendroglial cell lineage, or with the astrocyte-specific marker, glial fibrillary aciidic protein (GFAP). In addition, HAPI cells are capable of phagocytosis. We conclude that HAPI cells are of microglia/macrophage lineage. Exposing HAPI cells to lipopolysaccharide (LPS) induces the mRNAs for tumor necrosis factor-alpha (TNF-alpha) and inducible nitric oxide synthase (iNOS). LPS exposure also induces secretion of TNF-alpha and production of nitric oxide (NO) in HAPI cells. Because activation of microglia is associated with an increase in iron accumulation and ferritin expression, we tested the hypothesis that iron status affects the production of TNF-alpha and NO. Our studies demonstrate that both iron chelation and iron loading diminished the LPS-induced effect of TNF-alpha and NO. The results of this study indicate that HAPI cells possess the characteristics of microglia/brain macrophages, providing an alternative cell culture model for the study of microglia. In addition, we demonstrate that the activation of microglial cells could be modified by iron.

Abstract
Ubiquitin-specific processing proteases (UBPs) are characterized by a conserved core domain with surrounding divergent sequences, particularly at the N-terminal end. We previously cloned two isoforms of a testis UBP, UBP-t1 and UBP-t2, which contain identical core regions but distinct N termini that target the two isoforms to different subcellular locations (Lin, H., Keriel, A., Morales, C. R., Bedard, N., Zhao, Q., Hingamp, P., Lefrancois, S., Combaret, L., and Wing, S. S. (2000) Mol. Cell. Biol. 20, 6568-6578). To determine whether the N termini also influence the biochemical functions of the UBP, we expressed UBP-t1, UBP-t2, and the common core domain, UBP core, in Escherichia coli. The three isoforms cleaved branched triubiquitin at >20-fold faster rates than linear diubiquitin, suggesting that UBP-testis functions as an isopeptidase. Both N-terminal extensions inhibited the ability of UBP-core to generate free ubiquitin when linked in a peptide bond with itself, another peptide, or to small adducts. The N-terminal extension of UBP-t2 increased the ability of UBP-core to cleave branched triubiquitin. UBP-core removed ubiquitin from testis ubiquitinated proteins more rapidly than UBP-t2 and UBP-t1. Thus, UBP enzymes appear to contain a catalytic core domain, the activities and specificities of which can be modulated by N-terminal extensions. These divergent N termini can alter localization and confer multiple functions to the various members of the large UBP family.

Abstract
Previous studies have suggested an association between systemic lupus erythematosus (SLE) and an insertion/deletion polymorphism in the angiotensin-converting enzyme gene (ACE). This polymorphism consists of a 250-bp insertion/deletion of an alu repeat in the 16th intron of the ACE gene. Individuals homozygous for the deletion have a higher level of circulating enzyme. Due to the important role of this enzyme in regulating the renin--angiotensin and kallikrein--kininogen systems, it is possible that the ACE insertion/deletion may play a role in SLE, which can include vasculitis and vascular changes. Using primers flanking the insertion/deletion site, we have examined the ACE gene in lupus patients and family members using genomic DNA obtained from the Lupus Multiplex Registry and Repository (LMRR). We were unable to detect significant linkage or genetic association between the ACE gene and SLE.

Abstract
We report results on the ratio of midrapidity antiproton-to-proton yields in Au+Au collisions at sqrt[s(NN)] = 130 GeV per nucleon pair as measured by the STAR experiment at RHIC. Within the rapidity and transverse momentum range of /y/<0.5 and 0.4<p(t)<1.0 GeV/c, the ratio is essentially independent of either transverse momentum or rapidity, with an average of 0.65+/-0.01((stat))+/-0.07((syst)) for minimum bias collisions. Within errors, no strong centrality dependence is observed. The results indicate that at this RHIC energy, although the p-p pair production becomes important at midrapidity, a significant excess of baryons over antibaryons is still present.

Abstract
The authors looked at the explanations for their index of violent crimes as given by 69 incarcerated violent male offenders, respectively. We then examined the extent to which those explanations changed with the passing of time and with change in context. We found that explanations of impaired internal control increased with the passing of time, and that such explanation was given more often to mental health professionals rather than law enforcement professionals. Finally, we found that our subjects tended to give mental health professionals fewer explanations involving external control with the passing of time.

Abstract
OBJECTIVE To review the literature on women's knowledge of Pap smears, risk factors for cervical cancer, and cervical cancer. DATA SOURCES The review was based on a search of the relevant literature over a 10-year period using MEDLINE and CINAHL. DATA EXTRACTION Articles from relevant, indexed journals and textbooks published within the past decade were included. Seminal articles were included as appropriate. DATA SYNTHESIS Risk factors for the development of cervical cancer have been reevaluated. The case for human papillomavirus as the cause of cervical neoplasms has been strengthened. CONCLUSIONS Cervical cancer is associated with early sexual debut, number of lifetime sexual partners, nonuse of condoms, and infection with human papillomavirus. Cigarette smoking facilitates development of cervical cancer.

Abstract
Raltitrexed (Tomudex) is a specific inhibitor of thymidylate synthase with clinical activity in colorectal cancer. The combination of raltitrexed and 5-iodo-2'-deoxyuridine (IdUrd, a cytotoxic pyrimidine analog) resulted in increased IdUrd incorporation into DNA and exhibited in vitro synergism against colon and bladder human carcinoma cell lines. We designed a phase I trial to determine the MTD, pharmacokinetics, and biologic effects of escalating doses of the combination of IdUrd given as a 24-hour infusion after a raltitrexed 15-minute infusion every three weeks. Thirty-four patients received 95 courses of raltitrexed and IdUrd at doses ranging from raltitrexed 1 mg/m2 and IdUrd 750 mg/m2 to raltitrexed 2.5 mg/m2 and IdUrd 10,400 mg/m2. The median number of cycles administered was 2 (range 1-10). Dose limiting hematologic toxicity occurred at doses of raltitrexed 2.5 mg/m2 and IdUrd 10,400 mg/m2. In addition, we determined the mean plasma concentrations C(SS) of IdUrd, the iodouracil level at 22 hours and the IdUrd clearance. Raltitrexed did not appear to affect the pharmacokinetics of IdUrd in the dose range tested. The recommended phase II dose is raltitrexed 2 mg/m2 and IdUrd 10,400 mg/m2 repeated every three weeks. Evidence of potential antitumor activity was observed: 1 patient (with colon cancer) had a partial response while 15 others had stable disease.

Abstract
Meningococcal disease is an important cause of morbidity and mortality. A retrospective analysis was performed of all cases of invasive group-Y disease that were laboratory-confirmed in Scotland between 1992 and 1999. A total of 1881 meningococcal isolates were characterised, 78 of which were serogroup Y. The incidence of non-invasive group-Y disease remained level between 1992 and 1999. Only 12 isolates were from invasive disease, comprising five strain types. Invasive group-Y disease was associated mostly with the young or old. Serogroup-Y meningococcal disease was uncommon and a rare cause of invasive disease in Scotland between 1992 and 1999; however, it is essential that microbiologists are aware of its potential for increasing in incidence due to the recent introduction of the MenC vaccine, and its increased incidence in the USA.

Abstract
AIM To explore the concept of food security (when there is enough, appropriate and acceptable food available) in the adult New Zealand population using the National Nutrition Survey (NNS97). METHODS The stepwise development of indicators of food security included a literature search and focus groups with low income women and men. Key issues surrounding the procurement and provision of food were determined and eight indicator statements prepared for inclusion in NNS97, to be addressed by each participant on behalf of their household. RESULTS Prevalence was significantly higher (p<0.05) for females compared to males for the majority of indicator statements among New Zealand European & Others and Maori. New Zealand European & Others reported the most food security; Pacific people reported the least and Maori fell between the two. There was a significant increasing linear trend of food security with age (p<0.001), after adjusting for gender. "Food runs out in my/our household due to lack of money" was cited more often by female compared to male New Zealand European & Others in NZDep96 quartiles III and IV. CONCLUSION The issue of 'not having enough food' may be more prevalent in New Zealand than US or Australia. Among New Zealand European & Others the higher prevalence of insufficient food due to lack of money among females from NZDep96 quartiles III and IV suggests that males may be protected from this by their female partners. Food security needs to be improved among young adults, women, Maori and Pacific people in order to prevent longer term nutritional health consequences.

Abstract
Constipation represents a significant problem for people with advanced cancer. It ranks in the top three most uncomfortable symptoms experienced, causing pain and anorexia that ultimately result in misery. The negative impact upon the quality of life of the patient and their carers is significant. The key to the provision of effective care lies in the informed application of the nursing process, underpinned by a sound knowledge base in relation to the management of constipation. Theoretical knowledge enables appropriate preventative interventions to be planned in collaboration with other members of the multidisciplinary team. When preventative measures are not applied or are unsuccessful, informed assessment and care planning enables appropriate interventions to be applied in order to resolve constipation. This article will discuss the causes and management of constipation. The discussion focuses on assessment, setting goals with the patient and their carers, planning appropriate nursing interventions to support medical interventions and evaluating clinical outcomes.

Abstract
The performance of a modified target-controlled infusion system was investigated in 16 dogs undergoing routine dental work, by comparing the predicted concentrations of propofol in venous blood samples with direct measurements; the optimum targets for the induction and maintenance of anaesthesia were also identified. The performance of a target-controlled infusion system is considered clinically acceptable when the median prediction error, a measure of bias, is not greater than +/-10 to 20 per cent, and the median absolute performance error, a measure of the accuracy, is not greater than 20 to 30 per cent. The results fell within these limits indicating that the system performed adequately. The optimal induction target was 3 microg/ml, and anaesthesia of adequate depth and satisfactory quality was achieved with maintenance targets of between 2.5 and 4.7 microg/ml propofol. The system was easy to use and the quality of anaesthesia was adequate for dental work.
