Abstract
Post-translational modifications of nuclear factor (NF)-κB subunits provide a mechanism to differentially regulate their activity in response to the many stimuli that induce this pathway. However, the physiological significance of these modifications is largely unknown, and it remains unclear if these have a critical role in the normal and pathological functions of NF-κB in vivo. Among these, phosphorylation of the RelA(p65) Thr505 residue has been described as an important regulator of NF-κB activity in cell lines, but its physiological significance was not known. Therefore, to learn more about the role of this pathway in vivo, we generated a knockin mouse with a RelA T505A mutation. Unlike RelA knockout mice, the RelA T505A mice develop normally but exhibit aberrant hepatocyte proliferation following liver partial hepatectomy or damage resulting from carbon tetrachloride (CCl4) treatment. Consistent with these effects, RelA T505A mice exhibit earlier onset of cancer in the N-nitrosodiethylamine model of hepatocellular carcinoma. These data reveal a critical pathway controlling NF-κB function in the liver that acts to suppress the tumour-promoting activities of RelA.

Abstract
Over the 30 years of conflict, Northern Ireland escaped the worst excesses of illegal drug trafficking and usage. This was in large part due to the 'policing' of local community crime by paramilitaries. However, since the first 'cease-fire' in 1994 the province has witnessed a dramatic and unprecedented rise in the availability of illicit drugs. This increased availability reflects rising consumption of these drugs in the province. The aim of this study was to explore the perceptions that a sample of health and social care professionals' hold of illicit drug users in Northern Ireland. A survey methodology was used. Community settings across Northern Ireland were accessed. Focus groups and face-to-face interviews were used as data collection methods. Thirty-five health and social care professionals took part in this study. Thirty-two took part in six focus groups; three respondents underwent one-to-one interview. The participating professionals reported to have little or no education or training in the care and treatment of illicit drug users. Some stated that they would reject the offer of education and training in this area to prevent contact with illicit drug users. Many displayed strongly negative views of this client group, often expressing a preference not to care for or treat these people, preferring all their care to be given by specialists in illicit drug treatment. These findings indicate that most of the health and social care professionals who took part in this study appear unprepared and unwilling to meet the challenge of caring for illicit drug users. The findings will be of interest to service providers within and outside the UK.

Abstract
OBJECTIVES To determine if cervical length obtained with three-dimensional ultrasound correlated with the 'true cervical volume' and to evaluate the reliability and validity of transabdominal and transvaginal three-dimensional cervical volume measurement. METHODS This was a prospective observational study. Three-dimensional cervical volume measurements were made prior to hysterectomy in 28 women. Following hysterectomy the amputated cervical volume was calculated using water displacement. For the assessment of intra- and interobserver reliability, the intraclass correlation coefficient (ICC) was used. The index of concordance between the sonographic cervical volumes and those obtained by the reference standard (true cervical volume) was assessed with the limits of agreement method and the ICC. RESULTS Transabdominal cervical length and transvaginal cervical length correlated moderately with actual cervical volume; correlation coefficients were 0.64 and 0.57 (P < 0.05), respectively. Intraobserver reliability for both transabdominal and transvaginal cervical volume assessment was good (> 0.75). Interobserver reliability for transvaginal cervical volumes was similarly good (ICC = 0.90). However, for transabdominal measurements the interobserver reliability was poor (ICC = 0.51). The validity of both methods of three-dimensional volume assessment was poor (ICC < 0.75). This was reflected in the wide limits of agreement, which ranged from approximately - 25 mL to + 30 mL. CONCLUSION The reliability and validity of three-dimensional cervical volume measurement are poor. Clinical introduction of cervical volume measurement should be avoided at this time.

Abstract
We study the Dalitz plot of the decay D(+)-->K(-)pi(+)pi(+) with a sample of 15090 events from Fermilab experiment E791. Modeling the decay amplitude as the coherent sum of known Kpi resonances and a uniform nonresonant term, we do not obtain an acceptable fit. If we allow the mass and width of the K(*)(0)(1430) to float, we obtain values consistent with those from PDG but the chi(2) per degree of freedom of the fit is still unsatisfactory. A good fit is found when we allow for the presence of an additional scalar resonance, with mass 797+/-19+/-43 MeV/c(2) and width 410+/-43+/-87 MeV/c(2). The mass and width of the K(*)(0)(1430) become 1459+/-7+/-5 MeV/c(2) and 175+/-12+/-12 MeV/c(2), respectively. Our results provide new information on the scalar sector in hadron spectroscopy.

Abstract
Our universe obeys elegant laws that permit living beings to evolve. This can suggest divine design. So can fine tuning of physical and cosmological parameters in ways that seem essential to life. Understanding the idea of design is, however, difficult for many reasons. For instance, could a designer be said to "fine tune" through choosing all-dictating laws very carefully? Again, would taking advantage of early quantum indeterminacies be a case of design, or would it be design-destroying interference? Can we speak of "design" if God is not a mind but an abstract Platonic principle? And what if, as Spinoza believed, the structure of our universe is just the structure of divine thinking? If such thinking extended to other universes which were lifeless, could those "exhibit design" simply through being orderly?

Abstract
Early in 2001, the authors were awarded an Accompanying Measure by the Agri-Food Directorate of DG Research to assess the IMPACT of a selected subset of projects recently completed within the FAIR RTD program. We have three aims: To specifically evaluate the impact of 25 projects supported under the EU FAIR Programme. To develop and validate a methodology for assessing the impact of collaborative projects in the food area. To identify any generic messages which could relate to the forthcoming European Research Area (ERA). A series of Workshops are being held with FAIR participants and stakeholders around the Community to facilitate the development of the methodology. At the time of writing meetings have been held in the UK, Ireland and Denmark. Diet and Health will a key driver for innovation in food during the 21st century and will play a major role in both EU and national research. Participation in the HEALFO Food and Health Conference allowed us to meet and discuss IMPACT with an important group of both past and future contributors to EU research. This paper outlines the workshop methodology and outlines some interim findings together with emerging hypotheses.

Abstract
We have studied the diffractive dissociation into dijets of 500 GeV/c pions scattering coherently from carbon and platinum targets. Extrapolating to asymptotically high energies (where t(min)-->0), we find that when the per-nucleus cross section for this process is parametrized as sigma = sigma0Aalpha, alpha has values near 1.6, the exact result depending on jet transverse momentum. These values are in agreement with those predicted by theoretical calculations of color-transparency.

Abstract
We present the first direct measurements of the pion valence-quark momentum distribution which is related to the square of the pion light-cone wave function. The measurements were carried out using data on diffractive dissociation of 500 GeV/c pi(-) into dijets from a platinum target at Fermilab experiment E791. The results show that the /q&q> light-cone asymptotic wave function describes the data well for Q2 approximately 10 (GeV/c)(2) or more. We also measured the transverse momentum distribution of the diffractive dijets.

Abstract
We report results of a search for flavor-changing neutral current (FCNC), lepton flavor, and lepton-number violating decays of the D0 (and its antiparticle) into three and four bodies. Using data from Fermilab charm hadroproduction experiment E791, we examine modes with two leptons (muons or electrons) and a rho(0), K( *0), or straight phi vector meson or a nonresonant pi(pi), Kpi, or KK pair of pseudoscalar mesons. No evidence for any of these decays is found. Therefore, we present branching-fraction upper limits at 90% confidence level for the 27 decay modes examined (18 new).

Abstract
From a sample of 848+/-44 D(+)(s)-->pi(-)pi(+)pi(+) decays, we find gamma(D(+)(s)-->pi(-)pi(+)pi(+))/gamma(D(+)(s)-->straight phipi(+)) = 0.245+/-0.028(+0.019)(-0.012). Using a Dalitz plot analysis of this three body decay, we find significant contributions from the channels rho(0)(770)pi(+), rho(0)(1450)pi(+), f(0)(980)pi(+), f(2)(1270)pi(+), and f(0)(1370)pi(+). We also present the values obtained for masses and widths of the resonances f(0)(980) and f(0)(1370).

Abstract
From a sample of 1172 +/- 61 D(+)-->pi(-)pi(+)pi(+) decays, we find gamma(D(+)-->pi(-)pi(+)pi(+))/gamma(D(+)-->K-pi(+)pi(+)) = 0.0311 +/- 0.0018(+0.0016)(-0.0026). Using a coherent amplitude analysis to fit the Dalitz plot of these decays, we find strong evidence that a scalar resonance of mass 478(+24)(-23) +/- 17 MeV/c(2) and width 324(+42)(-40) +/- 21 MeV/c(2) accounts for approximately half of all decays.

Abstract
Underreporting of dietary intake has been observed consistently in food consumption surveys in affluent societies and in clinical studies in a variety of settings. Almost one third of quantitative 24-h recalls provided by adults in U.S. surveys appear to result in estimates that are biologically implausible. Underreporting has been linked to obesity in both the U.S. and Europe, with heavier individuals underreporting to a greater degree than lean persons. A relative dearth of data exists from developing countries and those in transition to address the question whether such underreporting is universal. We present the first data from a large survey of women in a rapidly urbanizing developing country to address this question. More than 4500 adult women in Egypt provided quantitative 24-h recalls of food intake on the previous day in 1993-1994, and weights and heights were measured. We compared the data, in terms of the ratio of reported energy intake to estimated basal metabolic rate, to data from 3010 women in the 1994-1996 U.S. Continuing Survey of Food Intake by Individuals, on whom quantitative 24-h recalls were also conducted. The Egyptian women reported food intakes consistent with FAO/WHO recommendations for energy intakes for women of comparable activity levels, whereas the data for U.S. women showed underreporting consistent with other U.S. surveys. Only 10% of Egyptian women reported energy intakes below accepted criteria for plausibility, compared with one third of American women. We discuss possible reasons for this difference, including cultural and food supply differences, and methodological differences between the two surveys.

Abstract
Physical inactivity is a major public health concern. Low levels of physical activity are reported in many subgroups of women including adolescent girls. More data are needed to better understand factors related to physical activity participation in adolescent girls. Therefore, we explored adolescent girls' reasons for participating and not participating in physical activity. Two independent samples were taken in California and Texas; the total sample included thirty-four African American and Latino girls. Six focus groups were conducted by trained facilitators. Based on independent qualitative analyses, six replicated themes emerged from the focus groups. Fun, social support, and concern with body image facilitated participation in activity. In contrast, negative experiences in physical education classes, concerns about appearance after activity, and lack of opportunity impeded participation in activity. Overall, the girls showed an interest in physical activity and identified activity motivators and barriers. We discuss the implications of our findings for future research.

Abstract
The costs of controlling and eradicating the epidemic of Newcastle disease in Northern Ireland in 1973 are presented. The parameters of the 1973 epidemic have been adjusted to simulate the effect of the same epidemic in 1997, taking into account the relative changes of input and output prices, and the changes in the structure of the poultry industry. The costs and their distribution between producers, government and the industry, in 1973 and 1997 are compared, and the costs of an alternative vaccination strategy are compared with the eradication policy in both years.

Abstract
A selective and specific high performance liquid chromatography method was developed to quantitate glucosamine hydrochloride in raw materials, dosage forms and plasma. Reverse phase chromatography using pre-column derivatization with phenylisothiocyanate, and ultraviolet detection (lambda = 254 nm) was used to quantify the eluate. The mobile phase consisted of MeOH/H2O/CH3COOH (10:89.6:0.04) and was pumped at a flow rate of 1.2 ml/min. The standard curves for glucosamine hydrochloride showed linearity (r > or = 0.99) over the selected concentration range from 6.65 to 16.63 microg/ml for raw materials and dosage forms. The precision of the dosage form assay, expressed as the % relative standard deviation (R.S.D.), was < 5% at all concentrations. The intra-day and inter-day accuracy, as indicated by the relative error (R.E.), ranged from - 2.54 to 2.70% for glucosamine hydrochloride. For the plasma assay, beagle dog plasma was used to prepare standard curves in the concentration range of 1.25-20 microg/ml. Precipitation of plasma proteins was accomplished with acetonitrile to separate interfering endogenous products from the compound of interest. The supernatant was derivatized using phenylisocyanate in phosphate buffer (pH = 8.3) and subsequently evaporated to dryness under a nitrogen stream at 42 degrees C. The residue was dissolved in 250 microl mobile phase and injected onto the chromatographic system. The assay was linear in concentration ranges of 1.25-20 microg/ml (r > or = 0.999). Intra- and inter-day precision was < or = 5.23 and 5.65%, respectively and the intra- and inter-day accuracy, indicated by R.E., ranged from - 8.6 to 10.35%. The method was found to be specific and with excellent linearity, accuracy and precision and is well suited for the quantitation of glucosamine hydrochloride in raw materials, dosage forms, and pharmacokinetic studies.

Abstract
The Uruguay Round of the General Agreement on Tariffs and Trade (GATT) established the World Trade Organization to supervise the reduction of barriers to, and liberalisation of, world trade. The application of sanitary and phytosanitary measures will be standardised to avoid use for protectionist purposes by countries or regional trade blocks. Harmonisation of animal disease control measures within regional blocks is essential if benefits to freer trade are to occur, but this harmonisation must be balanced against potential disease risks and costs associated with disease outbreaks. World trade in livestock products is concentrated among developed countries, although developing countries are responsible for approximately a third of poultry meat imports and exports. Despite liberalisation, the share of global trade by developing countries is unlikely to increase greatly in the short term. The benefits of trade and of freer trade are emphasised. Examples are given of the impacts of trade barriers on developing countries and of the harmonisation of European Union animal health standards. Economic implications for the future of greater global trade are assessed.

Abstract
The effects of age on late component (N100, P200, N200, and P300) event-related potentials (ERP) and reaction time (RT) were investigated in 50 normal subjects, 18 to 70 years of age. A conventional auditory oddball paradigm was employed. An equal number of subjects, as well as an equal number of males and females, were examined in each decade. There were no significant associations found between ERP amplitude and age. A significant positive correlation was found between age and N200/P300 latency. There were no significant effects of age on RT in the overall group. However, females had slower RT and decreased P200 and N200 amplitude as compared with males. Moreover, males had significant correlations between N200 latency and RT, whereas females showed significant correlations between P300 amplitude and RT. ERP/RT effects should be further explicated between gender, as well as across age.

Abstract
OBJECTIVE The objective of the study was to evaluate the screening potential of routine uterine arterial Doppler ultrasonography as a predictor of adverse pregnancy outcome. STUDY DESIGN All women (n = 6579) with singleton pregnancies undergoing a fetal anomaly scan at 18 to 20 weeks' gestation between January 1, 1994, and December 31, 1995, at Ninewells Hospital and Medical School were screened for the presence of uterine arterial notching. Women who had evidence of bilateral notching were rescanned at 22 to 24 weeks' gestation. Outcome measures included proteinuric hypertension, premature separation of the placenta, and birth weight z score. RESULTS The sensitivity and positive predictive value of uterine arterial notching as a predictor of adverse pregnancy outcomes was low. For all types of notching and disease, outcome sensitivity was never higher than 44% and positive predictive value was never higher than 27%. In contrast, the relative risk of adverse pregnancy outcome in the presence of uterine arterial notching was uniformly high for all disease outcomes (range of relative risk 3.5-30.7). Significant obstetric morbidity was seen in 57% of women with bilateral notches at 18 to 20 weeks' gestation and 72% of women with persistent bilateral notches. CONCLUSIONS As a screening test for adverse pregnancy outcomes, detection of uterine arterial notching is poor. Nevertheless, the presence of bilateral uterine arterial notching is associated with a significantly increased risk of adverse pregnancy outcome. In units performing routine anomaly screening, the addition of maternal uterine arterial Doppler ultrasonography may help to discriminate this small group of women at high risk.

Abstract
BACKGROUND A comparative analysis of outcomes of inguinal hernia repair performed under local (LA) and general anaesthesia (GA) by a single surgeon using a standardized technique of anterior transversalis repair was performed. Ninety-three cases were examined, 56 of which were cases of LA hernia repair. METHODS A retrospective analysis of the patient hospital record was performed with particular attention to intra-operative and post-operative analgesia requirements. RESULTS An overall series complication rate of 6.5% (6/93) is reported. Only one of 56 LA patients (2%) required more than 24 h of narcotic analgesic injections compared to 11% (4/37) in the GA group (P < 0.05). The mean total postoperative parenteral narcotic requirement in the LA group was 86+/-14 mg of pethidine as compared to the GA group who had a mean total requirement of 121+/-17 mg of pethidine (P > 0.08). CONCLUSIONS The LA infiltration technique is an effective method for inguinal hernia repair. This series demonstrates benefits in terms of length of hospital stay and a lower incidence of postoperative parenteral narcotic analgesic requirement although when post-operative parenteral narcotics were required by the LA group of patients, the difference in mean total pethidine requirement was not statistically significant.

Abstract
A reverse-phase High Performance Liquid Chromatographic (HPLC) method was developed for the analysis of metoprolol in the large number of human plasma samples obtained in in vitro-in vivo correlations (IVIVC) and bioavailability studies of extended release formulations of metoprolol tartrate. The metabolite, alpha-hydroxy metoprolol (OH-met), could also be quantified. The analytes were extracted from the plasma using solid phase columns, separated on a C-4 analytical column followed by fluorimetric detection. The linearity, precision, accuracy, stability, selectivity and ruggedness were validated for the concentration ranges of 1-400 ng ml-1 for metoprolol and 0.5-200 ng ml-1 for OH-met. The same chromatographic conditions were slightly modified to quantify dextromethorphan and its metabolite dextrorphan in urine in the concentration range 0.052-0.05 microgram ml-1 as a method for screening for fast metabolizers.

Abstract
Late component event related potentials (ERP) and concomitant electrodermal activity (EDA) measures of the orienting reflex (OR) were undertaken in 50 normal subjects. Our group recently developed a model to quantify electrodermal activity in conventional ERP paradigms (auditory oddball) with short interstimulus intervals (ISI). The method was used to classify the presence or absence of skin conductance response following each auditory target stimulus. Using a conventional paradigm in which data is traditionally averaged, single-trial target ERPs were sorted into those with a skin conductance response OR (ERP[+OR]) and those without (ERP[-OR]) an OR, and ERP sub-averages of the two groups were derived. The ERP(+OR) showed significantly larger P300 amplitudes and relatively earlier N200 and P300 latency than those of the ERP(-OR). These findings suggest that using concomitant SCR-ERP measures, separate ERP related processes can be determined, that are complementary to the traditional average measure.

Abstract
To examine the efficacy and toxicity of oral 3,4 diaminopyridine (DAP) in dosages up to 100 mg/day, 36 patients with multiple sclerosis (MS) enrolled in a randomized, double-blind, placebo-controlled, crossover trial. The primary outcome measure was improvement of a prospectively defined neurologic deficit, which was leg weakness in 34 patients. Secondary outcome measures included the patient's subjective response, scored manual motor testing (MMT) of leg strength, scored leg strength from videotaped motor testing (VMT), quadriceps and hamstrings strength (QMT) measured by isometric dynamometry, neuropsychological testing (NPT), ambulation index (AI), and Expanded Disability Status Scale (EDSS) score. Paresthesias and abdominal pain were common and were dose limiting in eight patients. Three patients had episodes of confusion, and one patient had a seizure while on DAP. Eight patients withdrew from the study, leaving 28 evaluable patients for the efficacy analysis. The prospectively defined neurologic deficit improved in 24 patients-22 on DAP and 2 on placebo (p = 0.0005). All improvements were in leg weakness. Subjective response and measures of leg strength and function (MMT, VMT, QMT, and AI) improved on DAP compared with placebo. Neither NPT nor EDSS scores improved. DAP treatment can induce improvements in leg strength in MS patients, but toxicity is limiting in many patients.

Abstract
Simulation of disease transmission in laying flocks infected with Salmonella enteritidis phage type 4 over a 48-week egg-production period indicated that the maximum weekly incidence risk could range from 0.05 to 0.28, and the maximum proportion of culture-positive birds could range from 0.20 to 0.77 of the flock, depending on the effective contact rate. If the egg contamination proportion were 0.08, contaminated egg production could vary from a weekly maximum of 0.42 per cent to 2.24 per cent depending on the effective contact rate, but the actual rate of contamination was more important in determining the numbers of infected eggs produced. The results from previous studies suggest that this proportion could range from 0.075 to 0.25. The model produced levels of infected and immune birds similar to those reported in the literature, suggesting effective contact rates of between 2 and 4.5. There is insufficient information on transmission cycles to validate the model, but it does provide a mechanism for consolidating research findings, reviewing areas for further research, and aiding more effective planning for disease control.

Abstract
The tegument of herpes simplex virus type 1 (HSV-1) virus particles is a complex assemblage of virus proteins whose relative proportions within virions are essentially constant for a particular strain of virus. To examine the processes controlling incorporation into the tegument, we constructed a HSV-1 recombinant that expresses two copies of gene UL49, which encodes the major tegument protein VP22. One copy specifies the unmodified form of VP22 under the control of the native promoter while the second expresses an epitope-tagged version of the protein via the human cytomegalovirus immediate early promoter. In cells infected with the recombinant virus, the overall levels of VP22 synthesized were about fivefold higher than those for wild-type virus, due to the high levels of expression of tagged protein. Analysis of virus particles revealed that the amount of VP22 in the tegument was approximately two- to threefold higher in recombinant virions and L-particles than in particles produced by wild-type virus. These results provide the first evidence that, for certain proteins, the level of polypeptide synthesis can act as a controlling factor for the amount of protein incorporated into tegument.

Abstract
The purpose of this study was to determine the effectiveness of a generalized water-based exercise program (WBE) compared to a land-based exercise program (LBE) on improving cardiorespiratory fitness, body composition, forward trunk flexion and strength measurements of elderly women aged 70 +/- 3.2 years (mean +/- SD). Forty-one healthy, sedentary women were selected to participate in the study and were randomly assigned to the LBE or WBE. The 2 groups exercised for 12 weeks, 3 times/week for 45 min. Fitness testing was done before, during and after training, and included measurements of peak aerobic power (VO2 peak), forward trunk flexion, sum of skinfolds, grip strength, curl-ups and push-ups. Between the tests performed before and after training, there were significant improvements in VO2 peak in both groups (p < 0.05) with no significant differences between the groups (p > 0.05). The LBE group also showed a significant improvement in the total number of curl-ups performed (p < 0.05). There were no significant differences in trunk forward flexion, total (right plus left) grip strength, push-ups, waist to hip ratio, sum of skinfolds or body mass index between the tests performed before and after training over time within groups or between groups (p > 0.05). The results show that general exercise interventions resulted in improvements in cardiovascular fitness (for both groups) and abdominal endurance (in the LBE only), but the two exercise programs used were not specific enough or long enough to cause improvements in muscular strength, flexibility or body composition. Furthermore, except for changes in abdominal endurance, the type of exercise venue (land vs. water) did not have a significant effect on the results obtained.

Abstract
As the US health care system strives to function efficiently, encourage preventive and primary care, improve quality, and overcome nonfinancial barriers to care, the potential exists for community health workers to further these goals. Community health workers can increase access to care and facilitate appropriate use of health resources by providing outreach and cultural linkages between communities and delivery systems; reduce costs by providing health education, screening, detection, and basic emergency care; and improve quality by contributing to patient-provider communication, continuity of care, and consumer protection. Information sharing, program support, program evaluation, and continuing education are needed to expand the use of community health workers and better integrate them into the health care delivery system.

Abstract
In a case-control controlled study of 86 women identified as having bilaterally 'notched' uterine arterial waveform patterns at 18 weeks, the presence of bilateral 'notched' uterine arterial waveforms at that time was associated with the subsequent development of hypertension and small-for-gestational-age infants, but the predictive value was poor. For those women in whom the bilateral uterine 'notches' were observed to persist to 24 weeks, the relative risk of developing proteinuric hypertension increased 14 times, and in these women the positive predictive value for the subsequent development of hypertension increased to 58.6% when compared with their matched controls. The identification of women with persistent bilateral uterine 'notches' provides a means of identifying women at significant risk of hypertensive and growth disorders at a stage when therapeutic intervention aimed at limiting the severity of the disease and its associated complications could be commenced.

Abstract
Demographic, epidemiological and socio-economic trends in developing countries are creating new mortality and morbidity patterns for both women and men. Women's health needs will increasingly include problems beyond reproduction, and health interventions must take into consideration the important characteristics of women's lives that affect their ability to address these problems. Meeting the changing health needs of women in developing countries will require more comprehensive health interventions guided by innovative, interdisciplinary research. A broader conceptualization of women's health needs, and the constraints and opportunities associated with meeting those needs, is necessary to avoid overly simplistic assigning of responsibility, which can lead to blaming organizations, disciplines and individuals, including women themselves, for persistent health problems and underutilization of existing services.

Abstract
BACKGROUND Hypertension commonly occurs after cardiac surgery and requires therapy to prevent the potentially deleterious effects. METHODS AND RESULTS After coronary artery bypass graft surgery (CABG), 177 patients with elevated blood pressure > or = 90 mm Hg during the initial 6-hour postsurgical period were selected for this random blinded, parallel study to receive intravenous infusions of either isradipine (n = 90) or sodium nitroprusside (n = 87). Isradipine produced a statistically significant decrease in mean arterial pressure (MAP, delta-23 mmHg) during a 90-minute treatment period. Target MAP (< or = 85 mmHg or a decrease of 10 mmHg, if baseline MAP was between 90 and 95 mmHg) was achieved in 94% of patients 30 minutes after initiation of isradipine infusion (total mean dose, 411 micrograms); target MAP was achieved in 75% of nitroprusside-treated patients (total mean dose, 1708 micrograms). The mean time to control MAP was 18 minutes for isradipine compared with 24 minutes for nitroprusside. Global smoothness in MAP control was graded on a scale of 0 (not controlled) to 5 (excellent). Approximately 76% of isradipine-treated patients received a rating of > or = 3 (mean score, 3.5); 40% of the sodium nitroprusside-treated patients achieved a score of > or = 3 (mean score, 2.0). Both isradipine and nitroprusside produced statistically significant reductions in systolic and diastolic blood pressures, a decrease in systemic vascular resistance, and increases in heart rate, cardiac index, and stroke volume index. Isradipine produced no significant decreases in pulmonary artery occlusion wedge pressure compared with nitroprusside. CONCLUSIONS Intravenous isradipine was effective and well tolerated in patients with hypertension after CABG and offers an additional therapeutic option to treat patients after cardiac surgery.

Abstract
The authors examined the robustness of optimal sampling theory in estimating the parameter values of two different populations of patients receiving a constant rate, half-hour intravenous infusion of theophylline. One population consisted of smokers; the other included nonsmokers. The smoking population was predicted to have a serum clearance approximately 50% greater than the nonsmokers because of an induction of the cytochrome P450 system. After an initial study to provide both patient-specific and population mean parameter values, optimal sampling strategies that were derived from each population (seven sample split designs) and the patient's seven sample and four sample design were determined. A second study was performed with an overall sampling strategy that was superset of all the above strategies. The analysis of all samples served as the reference for the parameter values. Bias and precision of the values determined with each of the optimal sampling sets (seven sample sets based on the "correct" and "wrong" populations, the patient's seven and four sample sets) were determined relative to these reference values. Irrespective of the sample set used for analysis, unbiased and precise parameter estimates, particularly of hybrid parameters were provided. With the patient's four sample set, Vss was significantly biased, but the value of (2.2%) was clinically insignificant. The authors conclude that optimal sampling theory, as implemented in this study, provides robust estimates of important pharmacokinetic parameter values, even when errors of 50% are present in the clearance of the population used to calculate the optimal sampling design.

Abstract
The compatibility and stability of labetalol hydrochloride in combination with various critical care drugs was evaluated. Labetalol hydrochloride 1.0 mg/mL was combined in 5% dextrose injection with equal volumes of each of the following drugs: dobutamine 2.5 mg/mL (as the hydrochloride salt), dopamine hydrochloride 1.6 mg/mL, morphine sulfate 0.5 mg/mL, nitroglycerin 0.2 mg/mL, and ranitidine 0.6 mg/mL (as the hydrochloride salt). The mixtures were placed in duplicate Y-site administration sets. Visual inspection, pH determination, and high-performance liquid chromatography were performed in duplicate on samples removed at zero, two, and four hours. No change in pH or appearance occurred throughout the study. All drug concentrations remained above 90% of the initial concentration in each combination. Labetalol hydrochloride 1.0 mg/mL and dobutamine 2.5 mg/mL (as the hydrochloride salt), dopamine hydrochloride 1.6 mg/mL, morphine sulfate 0.5 mg/mL, nitroglycerin 0.2 mg/mL, or ranitidine 0.6 mg/mL (as the hydrochloride salt) in 5% dextrose injection were stable and compatible for up to four hours at 20-25 degrees C during simulated Y-site injection.

Abstract
Because 4-aminopyridine (AP) improves residual deficits in some multiple sclerosis (MS) patients but has a narrow toxic-to-therapeutic margin, we compared the safety and efficacy of two target peak serum concentration ranges (low: 30 to 59 ng/ml and high: 60 to 100 ng/ml). We enrolled eight MS patients with temperature-sensitive visual and motor deficits in a randomized, placebo-controlled, double-blind, crossover trial of short-term oral AP treatment. We randomized patients to a sequence of three treatments on three separate days: placebo, low serum concentration, and high serum concentration. We determined dosing to achieve the desired steady-state peak serum concentration ranges from a test dose and population pharmacokinetic parameters using bayesian estimation. Contrast sensitivity, standard neurologic examination, ratings of videotaped neurologic examinations, and quantitative strength assessment all improved with treatment, but flicker fusion frequency, visual evoked response latencies, and Expanded Disability Status Scale scores did not. All patients experienced side effects during the high-serum-concentration arm. A grand mal seizure occurred at a serum AP level of 104 ng/ml, and an acute confusional episode occurred at 114 ng/ml. AP treatment produced improvements in residual deficits in MS patients, but the occurrence of significant toxicity suggests that AP serum levels should be monitored and peak levels above 100 ng/ml should be avoided. Concentration-control methodology may be useful in testing putative treatments for other neurologic diseases.
