Abstract
This study is concerned with the application of advanced multimedia technology to the development of a programme aimed at raising awareness of information and communications technology (ICT) amongst health professionals in Ireland. The programme is delivered in the form of a symposium supplemented by a multimedia CD and associated web site. It examines how ICT can be used effectively in healthcare across all sectors - primary, secondary and tertiary - with a strong emphasis on supporting shared care. The aim is to empower users to make informed technological choices and to actively participate in the exploitation of ICT in the health sector. The programme was successfully completed and delivered to over 2300 health professionals across Ireland and follow-up activities include the active encouragement of leaders and champions within the sector. This will be supported by interactive web-based education and training material focused on specialised topics of particular interest within the broader context of continuing medical education (CME).

Abstract
OBJECTIVE To examine the prevalence, co-occurrence, and correlates of sleep problems among elementary school children. DESIGN Survey. SETTING General community. PARTICIPANTS The parents of 987 children aged 5 to 12 years completed an anonymous survey distributed in their children's schools. MAIN OUTCOME MEASURES The survey form asked about background characteristics, children's sleep environment, sleep habits, adult interventions, sleep history, and specific sleep problems. RESULTS Bedtime resistance was the most prevalent sleep problem (27%). Sleep-onset delays (11.3%), night waking (6.5%), morning wake-up problems (17%), and fatigue complaints (17%) were also common. Among children with sleep-onset problems, 80% displayed bedtime resistance, while 34% of bedtime resisters had onset problems. Onset problems correlated with more fears, night waking, psychiatric and medical conditions, the need for reassurance and caregiver proximity, and history of sleep problems. Bedtime resistance was associated with an inconsistent bedtime and falling asleep away from bed. Those who display delayed sleep onset and bedtime resistance also wake later, suggesting that sleep-phase delays may maintain these problems. CONCLUSIONS The results confirm bedtime resistance as parents principal sleep-related complaint for this age group but reveal a subgroup more prone to insomnia, night waking, and anxiety-related features. Phase delay findings suggest the importance of limits around wake-up time as well as bedtime. The results highlight the importance of distinctly evaluating bedtime resistance, sleep onset, sleep maintenance, waking, and emotional adjustment.

Abstract
This study investigated steady-state auditory evoked responses to pulsed frequency modulations (FM) of a continuous tone in normal children ranging in age from 6 to 12 years. We examined variations in response amplitude and phase as a function of age, recording site, and FM pulse duration. The surface topography of these evoked potentials suggested a relatively broad distribution with maximal responses observed at frontal electrode sites, smaller responses from parietal leads and the smallest responses were evident at the temporal lobe placements. Response parameters varied significantly as a function of pulse duration. Fifty milliseconds pulses elicited responses that were on average 20% larger than 100 ms FM pulses. Mean phase differences suggested that responses to the 100 ms pulses also lagged behind responses to the 50 ms pulses by the equivalent of 20 ms. There were no significant age-related variations in response amplitude. Phase varied with age only in response to the 50 ms FM pulses. The findings indicated that steady-state responses are sensitive to temporal parameters of frequency change present in pulsed modulations. The possibility is raised that this paradigm may be clinically useful in detecting dysfunction of specialized auditory mechanisms involved in frequency modulation analysis.

Abstract
We developed and validated a noninvasive method to quantify fecal estrogens and progestins as a tool for monitoring long-term ovarian activity in free-ranging African elephants. The lag times between iv injection of [(3)H]estradiol and [(14)C]progesterone and peak excretion of radioactivity in urine and feces were approximately 4 hr and 48 hr, respectively. The majority of progesterone metabolites recovered was excreted in feces (55%) versus urine (45%), whereas comparatively little of the recovered estradiol metabolites were excreted in feces (5%) compared to urine (95%). Intrasample variation in fecal hormone concentrations was extremely high but could be substantially reduced by extracting well-mixed fecal powder from freeze-dried samples, taken from the central or premixed portion of the wet sample. This method resulted in a close correspondence between matched serum and fecal progestins (mean correlation = 0.81, range 0.61-0.94) collected from five nonpregnant adult females over a 7-month period. Fecal estrogen profiles were more ambiguous, tending to overlap with those of fecal progestins. We conclude that analyses of fecal progestins can provide an effective, noninvasive means of characterizing ovarian activity in free-ranging African elephants.

Abstract
OBJECTIVES We hypothesized that a) perfluorocarbon-associated gas exchange could be accomplished in normal large sheep; b) the determinants of gas exchange would be similar during perfluorocarbon-associated gas exchange and conventional gas ventilation; c)in large animals with lung injury, perfluorocarbon-associated gas exchange could be used to enhance gas exchange without adverse effects on hemodynamics; and d) the large animal with lung injury could be supported with an FIO2 of <1.0 during perfluorocarbon-associated gas exchange. DESIGN Prospective, observational animal study and prospective randomized, controlled animal study. SETTING An animal laboratory in a university setting. SUBJECTS Thirty adult ewes. MEASUREMENT AND MAIN RESULTS Five normal ewes (61.0 +/- 4.0 kg) underwent perfluorocarbon-associated gas exchange to ascertain the effects of tidal volume, end-inspiratory pressure, and positive end-expiratory pressure (PEEP) on oxygenation. Respiratory rate, tidal volume, and minute ventilation were studied to determine their effects on CO2 clearance. Sheep, weighing 58.9 +/- 8.3 kg, had lung injury induced by instilling 2 mL/kg of 0.05 Normal hydrochloric acid into the trachea. Five minutes after injury, PEEP was increased to 10 cm H2O. Ten minutes after injury, sheep with Pao2 values of <100 torr (<13.3 kPa) were randomized to continue gas ventilation (control, n=9) or to institute perfluorocarbon-associated gas exchange (n=9) by instilling 1.6 L of unoxygenated perflubron into the trachea and resuming gas ventilation. Blood gas and hemodynamic measurements were obtained throughout the 4-hr study. Both tidal volume and end-inspiratory pressure influenced oxygenation in normal sheep during perfluorocarbon-associated gas exchange. Minute ventilation determined CO2 clearance during perfluorocarbon-associated gas exchange in normal sheep. After acid aspiration lung injury, perfluorocarbon-associated gas exchange increased PaO2 and reduced intrapulmonary shunt fraction. Hypoxia and intrapulmonary shunting were unabated after injury in control animals. Hemodynamics were not influenced by the institution of perfluorocarbon-associated gas exchange. CONCLUSIONS Tidal volume and end-inspiratory pressure directly influence oxygenation during perfluorocarbon-associated gas exchange in large animals. Minute ventilation influences clearance of CO2. In adult sheep with acid aspiration lung injury, perfluorocarbon-associated gas exchange at an FIO2 of <1.0 supports oxygenation and improves intrapulmonary shunting, without adverse hemodynamic effects, when compared with conventional gas ventilation.

Abstract
The crystallographic structure of bovine prothrombin fragment 1 bound with calcium ions was used to construct the corresponding human prothrombin structure (hf1/Ca). The model structure was refined by molecular dynamics to estimate the average solution structure. Accommodation of long-range ionic forces was essential to reach a stable solution structure. The gamma-carboxyglutamic acid (Gla) domain and the kringle domain of hf1/Ca independently equilibrated. Likewise, the hydrogen bond network and the calcium ion coordinations were well preserved. A discussion of the phospholipid binding of the vitamin K-dependent coagulation proteins in the context of the structure and mutational data of the Gla domain is presented.

Abstract
The Msx-1 homeobox gene is expressed in various contexts during vertebrate development, including the progress zone of the avian and mouse limb bud. Expression of mouse Msx-1 in a cultured myogenic cell line conferred a transformed phenotype and inhibited fusion into myotubes. It has been proposed that Msx-1 expression is required to maintain certain cells in a proliferating and undifferentiated state and may be associated with the ability to regenerate limbs. Urodele amphibians such as the newt regenerate their limbs by formation of a growth zone or blastema, and we have isolated and sequenced newt Msx-1 (NvMsx-1) from a limb blastemal cDNA library. NvMsx-1 expression was detectable in RNA preparations from both limb and tail and their regeneration blastemas, although cultured cells established from limb blastemal mesenchyme gave negative results. When either COS cells or cultured newt blastemal cells were cotransfected with an expression vector for NvMsx-1 and reporter plasmids containing multiple homeobox protein binding sites, NvMsx-1 repressed reporter expression. If NvMsx-1 was expressed together with a marker enzyme in cultured newt blastemal cells, no significant difference in DNA synthesis was observed relative to control transfectants. When myogenic mononucleate cells were transfected with NvMsx-1 and subsequently exposed to low serum to promote fusion, the fraction of Msx-1 positive cells in myotubes was comparable to a control transfected population analysed in the same culture. These results indicate that although Msx-1 expression could be important for limb regeneration, it does not exert a cell-autonomous effect on proliferation or myogenic differentiation of cultured blastemal cells.

Abstract
Binding protein (BiP) is a widely distributed and highly conserved endoplasmic-reticulum luminal protein that has been implicated in cotranslational folding of nascent polypeptides, and in the recognition and disposal of misfolded polypeptides. Analysis of cDNA sequences and genomic blots indicates that soybeans (Glycine max L. Merr.) possess a small gene family encoding BiP. The deduced sequence of BiP is very similar to that of other plant BiPs. We have examined the expression of BiP in several different terminally differentiated soybean organs including leaves, pods and seed cotyledons. Expression of BiP mRNA increases during leaf expansion while levels of BiP protein decrease. Leaf BiP mRNA is subject to temporal control, exhibiting a large difference in expression in a few hours between dusk and night. The expression of BiP mRNA varies in direct correlation with accumulation of seed storage proteins. The hybridization suggests that maturing-seed BiP is likely to be a different isoform from vegetative BiPs. Levels of BiP protein in maturing seeds vary with BiP mRNA. High levels of BiP mRNA are detected after 3 d of seedling growth. Little change in either BiP mRNA or protein levels was detected in maturing soybean pods, although BiP-protein levels decrease in fully mature pods. Persistent wounding of leaves by whiteflies induces massive overexpression of BiP mRNA while only slightly increasing BiP-protein levels. In contrast single-event puncture wounding only slightly induces additional BiP expression above the temporal variations. These observations indicate that BiP is not constitutively expressed in terminally differentiated plant organs. Expression of BiP is highest during the developmental stages of leaves, pods and seeds when their constituent cells are producing seed or vegetative storage proteins, and appears to be subject to complex regulation, including developmental, temporal and wounding.

Abstract
Behavioral patterns over time were assessed during the first 24 days of hospitalization for 98 child psychiatric inpatients. Staff completed daily behavioral monitoring and ratings. Patients were categorized as improved, unchanged or deteriorated during this time. Thirty-four percent of patients initially exhibited well-controlled behavior, but then significantly worsened after a period averaging 6.8 days. This result empirically supports the "honeymoon" phenomenon. Other patients showed either improvement during the initial period (15%), no change (30%), or could not be reliably classified (21%). Therefore, many child inpatients show rapid symptom stabilization after admission, but a large number then worsen. Clinical, scientific and administrative implications of these results are discussed.

Abstract
We evaluated regional cerebral blood flow with technetium 99mTc hexamethylpropyleneamineoxime single photon emission computed tomography (SPECT) in 20 children and adolescents with neurologic dysfunction of varied etiology and abnormal electroencephalograms (EEGs). All patients were also examined with computed tomography (CT) and magnetic resonance imaging (MRI). Abnormal perfusion was found in 17 (85%) of 20 SPECT scans. Abnormal CT or MRI scans were noted in nine (45%) and in 10 (50%) of 20 cases, respectively. In eight (73%) of 11 cases with normal CT scans and in seven (70%) of 10 with normal MRI scans, the SPECT scan was abnormal. Abnormal regional cerebral blood flow on SPECT scans correlated better with EEG abnormalities than with neurologic examination or CT or MRI scan findings. We conclude that in children and adolescents with a spectrum of neurologic diseases and abnormal EEGs, abnormalities of brain structure or function are more likely to be documented by SPECT than by CT or MRI scans. SPECT findings correlate well with the location and type of EEG abnormality.

Abstract
This study evaluated the effectiveness of a 16-week intensive cognitive training program in stimulant-treated, academically deficient ADDH boys. Cognitive training focused exclusively on academic skills and tasks, and included attack strategy training as well as self-monitoring and self-reinforcement of problem-solving behaviors and response accuracy. Control groups included remedial tutoring plus medication, and medication alone. Despite the scope of the program, the results provided no support for the notion that academically based cognitive training ameliorates the performance and achievement of academically deficient ADDH youngsters. Further, this intervention did not enhance self-esteem or attributional perceptions of academic functioning. There was poor agreement between teacher ratings of academic competence and test score changes. The lack of concordance between measures, and the scarcity of academically deficient ADDH children are discussed.

Abstract
The authors administered a structured psychiatric interview, the Kiddie-SADS, and the dexamethasone suppression test (DST) to 42 adolescent psychiatric inpatients. Of the 26 adolescents diagnosed as depressed, nine (36.4%) failed to suppress cortisol, and of the 16 nondepressed adolescents, three (18.8%) also failed to suppress cortisol. There was no significant association between the diagnosis of depression and the failure to suppress cortisol during the DST. The use of the DST to diagnose endogenous major depressive illness in adolescents seems to be a premature clinical application of an important investigative finding.

Abstract
The inadequacy of a definition of attitudinal terms has complicated the interpretation of many food habit studies. This review has focused on the multidimensional character of the word "attitude" as an aid to gaining insight into food habit development and change. The five definitional categories presented (attitudes as preferences, as overt food behavior, as willingness or ability to change, as agreement among family members, and as complexity of meanings) do not preclude other definitions. Knowledge of attitude studies can foster understanding of the link between nutritional knowledge and actual behavior, as well as help practitioners to be more effective in formulating objectives and developing techniques for nutrition education. The various dimensions and meanings of attitudes indicate the need for continued research to clarify the effect of well defined attitude variables on food habits.
