Abstract
Mucociliary clearance (MCC) is an important mechanism for removing inhaled particles, secretions and cellular debris from the respiratory tract. Here, a direct measurement of tracheal mucus velocity (TMV) for assessment of MCC, suitable for clinical and research use, is reported, and a comparison is made of TMV in normal subjects and patients with chronic obstructive pulmonary disease (COPD). A 0.1-mL bolus of radiolabelled (2-5 MBq), technetium-labelled macroaggregated human albumin (99mTc MAA) was injected through the cricothyroid membrane into the trachea of 20 young (< 50 yrs) and 12 older (> 50 yrs) normal subjects and 34 patients with COPD. Repeat studies were carried out in 13 normal subjects and 16 COPD patients. Movement of the bolus in the trachea was recorded (15 min) using a gamma camera interfaced to a computer. Data were analysed using specifically designed software. The test was well tolerated by subjects and patients, and no significant adverse events were reported. No significant differences were observed between data recorded from different regions of the bolus (leading edge, peak, trailing edge) by analysis of variance (ANOVA). Bland-Altman plots of the repeat studies indicated that data were more variable in normal subjects (coefficient of repeatability (COR) 10.3 mm.min-1) than in COPD patients (COR 5.5 mm.min-1). TMV (mean +/- SD) in young normal subjects (n = 20) was 10.7 +/- 3.5 mm.min-1. TMV was reduced in older normal subjects (n = 12; 6.5 +/- 2.6 mm.min-1) and further reduced in COPD (n = 34; 2.1 +/- 2.7 mm.min-1). In conclusion, this technique can be used to measure tracheal mucus velocity rapidly and safely in healthy subjects and patients with respiratory tract disease. This study has confirmed that tracheal mucus velocity declines with age and is further impaired in patients with chronic obstructive pulmonary disease.

Abstract
Subjects had to judge the size of a tactile stimulus held in the unseen hand, while a visible phantom hand representing that unseen hand held a tactile stimulus of same or different size. No asymmetries in interference effects were found that could be related to hand or handedness. The method lends itself to quantification of virtual reality box illusions and can be used to evaluate the role of experience and sources of variability in the strength of the illusion across subjects.

Abstract
BACKGROUND PURPOSE An association between hyperglycaemia and poor outcome has been reported in critically ill adults and children. The authors investigated the incidence of hyperglycemia in infants with necrotizing enterocolitis (NEC) and the relationship between glucose levels and outcome in these infants. METHODS All glucose measurements (n = 6508) in 95 neonates with confirmed NEC admitted to the surgical intensive care unit (ICU) were reviewed. Maximum glucose concentration during admission (Gmax) was determined for each infant and correlated with outcome. Eleven infants in whom treatment was withdrawn within 24 hours owing to unsalvageable panintestinal NEC were excluded from the analysis. RESULTS Glucose levels ranged from 0.5 to 35.0 mmol/L and 69% of infants became hyperglycemic (>8 mmol/L) during their admission. Thirty-two infants died. Mortality rate tended to be higher in infants with Gmax greater than 11.9 mmol/L compared with those with Gmax less than 11.9 mmol/L, and late (>10 days admission) mortality rate was significantly higher in these infants (29% v, 2%; P =.0009). Median length of stay was 9.3 days. Linear regression analysis indicated that Gmax was significantly related to length of stay (P <.0001). CONCLUSIONS Hyperglycemia is common in infants with NEC admitted to the ICU and is associated with an increase in late mortality and longer intensive care stay. Aggressive glycemic control may improve outcome in this group of infants.

Abstract
Cancer of unknown origin (CUO) is defined by the absence of any primary tumour in biopsy-proved metastatic cancer. CUO accounts for a 5-10% of all malignancies. These tumors have a specific biology with clinical characteristics of rapid progression and atypical metastases. Diagnostic evaluation is directed at the identification of treatable subset. Accurate diagnostic workup is crucial because both prognosis and survival rates depend mainly on detection of the primary tumor site. Although these patients undergo extensive imaging procedures, nuclear medicine techniques are under-utilized despite their ability of providing molecular information. Positron emission tomography has an emerging role in this clinical challenge along with other nuclear medicine methods including, bone scan, thyroid scintigraphy.

Abstract
OBJECTIVES (1) To review the history of the tobacco industry supported Australian Tobacco Research Foundation (ATRF)(1970-1994) for evidence of the industry's use of the Foundation to further its objectives that "more research was needed" on smoking and health and to promulgate the view that nicotine was not addictive. (2) To review efforts by public health advocates to discredit the ATRF as a public relations tool used by the Australian industry. METHODS Systematic search of previously internal industry documents released through the US Master Settlement Agreement. RESULTS The ATRF was headed by prestigious Australian medical scientists, with at least one considered by the industry to be "industry positive". An international ATRF symposium on nicotine was vetted by the industry and heavily attended by industry approved scientists. Following sustained criticism from the health and medical community about the industry's creation of the ATRF to further its objectives, the ATRF's scientific committee was provoked to publicly declare in 1988 that smoking was a causative agent in disease. This criticism led to growing ATRF boycotts by scientists and substandard applications, causing the industry to see the ATRF as being poor value-for-money and eventually abandoning it. CONCLUSIONS The raison d'etre for the ATRF's establishment was to allow the Australian industry to point to its continuing commitment to independent medical research, with the implied corollary that tobacco control measures were premature in the face of insufficient evidence about tobacco's harms. Sustained criticism of tobacco industry funded research schemes can undermine their credibility among the scientific community.

Abstract
The radiative decay B-->phi K gamma is observed for the first time. The branching fraction for the charged B--->phi K- gamma decay mode is measured to be B(B--->phi K- gamma)=(3.4+/-0.9+/-0.4)x10(-6). The photon energy distribution for the B--->phi K- gamma decay is presented. The signal for the neutral B(0)-->phi K(0)gamma decay mode is not statistically significant and an upper limit, B(B(0)-->phi K(0)gamma)<8.3x10(-6) at 90% C.L., is set. The analysis is based on a data set of 90 fb(-1) collected by the Belle experiment at the e(+)e(-) asymmetric collider KEKB.

Abstract
The objective of this study was to gain insight into the patients' decision-making for migraine and chronic daily headache management. Patients were recruited by theoretical sampling in Surrey (UK). Semi-structured and tape-recorded interviews (n = 13) were conducted, transcribed verbatim, coded and analysed according to the grounded theory methodology. Thirteen patients (8 migraine and 5 chronic daily headache) described their management. All patients employed multiple behaviours to manage their headaches. From the patients' descriptions emerged their decision-making. Based on experience, perceptions and new information, the decision-making process involved four stages: headache severity, evaluation, decision making and behaviours. Although the participants were passive with regards to certain management strategies, overall they were actively involved in treating and preventing their headaches. Furthermore, they were active decision-makers in choosing appropriate management. Migraine and chronic daily headache patients are actively involved in managing their headaches. They are key decision-makers and should not be overlooked as a resource for effective management.

Abstract
Increased serum levels of S100B are positively correlated with multiple forms of CNS damage, such as stroke, CNS trauma and neurodegenerative diseases, but also in psychiatric disorders. However, it is currently not known whether increased serum levels of S100B reflect a neuroregenerative or neurodegenerative response. Since glutamate receptor overactivation (excitotoxicity) may contribute to neuronal pathology in psychiatric disorders, we investigated the effect of S100B on N-methyl-d-aspartate (NMDA)-induced neuronal cell death. Here we demonstrate that very low concentrations of S100B significantly protect primary rat hippocampal neurons against NMDA toxicity by activation of transcription factors of the Rel/nuclear factor kappaB (NF-kappaB) family. Further experiments suggest that i) S100B activated expression of the receptor of advanced glycation products (RAGE) gene in neurons and ii) S100B induced a unique composition of the active NF-kappaB complex consisting of the p65 and c-Rel subunits suggesting a novel mechanism for NF-kappaB activation involved in S100B-mediated neuroprotection. Our data suggest that S100B secreted during the glial response to brain injury potently activates p65/c-Rel in a RAGE-dependent manner and may exert neuroprotective and neuroregenerative effects in psychiatric disorders.

Abstract
The efficacy of sequencing batch reactors (SBRs) to provide high levels of biological nutrient removal has been extensively demonstrated around the world. Environmental Solutions International (ESI) has now constructed over 20 full-scale SBR plants and has confirmed that nutrient removal is enhanced via the process of simultaneous nitrification and denitrification. Over 18 months of operational data from two plants, operating in distinctly different catchments, processing an average of between 2,000 and 2,500 m3/d of wastewater, has clearly shown the efficacy and robustness of the ESI SBR-BNR process. Median effluent total nitrogen and total phosphorus values of 3 mg/L and <0.6 mg/L, respectively, were demonstrated over the 18-month period. This high level of nutrient removal is attributed to the design of the bio-selector which maximises carbon storage for the subsequent denitrification reactions, the effective aeration control which ensures no over-aeration during the air-on cycle as well as the level of operational control provided at these two plants.

Abstract
We present an improved measurement of CP-violation parameters in B0-->phiK(0)(S), K(+)K(-)K(0)(S), and eta(')K(0)(S) decays based on a 140 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e(+)e(-) collider. One neutral B meson is fully reconstructed in one of the specified decay channels, and the flavor of the accompanying B meson is identified from its decay products. CP-violation parameters for each of the three modes are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays. We find that the observed CP asymmetry in the B-->phiK(0)(S) decay differs from the standard model (SM) expectation by 3.5 standard deviations, while the other cases are consistent with the SM.

We report evidence for the decay B0-->pi(0)pi(0). The analysis is based on a data sample of 152x10(6) BBmacr; pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB e(+)e(-) storage ring. We detect a signal for B0-->pi(0)pi(0) with a significance of 3.4 standard deviations, and measure the branching fraction to be [1.7+/-0.6(stat)+/-0.2(syst)]x10(-6).

Abstract
We report evidence for the decay mode B-->phiphiK based on an analysis of 78 fb(-1) of data collected with the Belle detector at KEKB. This is the first example of a b-->sssss transition. The branching fraction for this decay is measured to be B(B+/--->phiphiK+/-)=(2.6(+1.1)(-0.9)+/-0.3)x10(-6) for a phiphi invariant mass below 2.85 GeV/c(2). Results for other related charmonium decay modes are also reported.

Abstract
We report genetic characterization of isochromosome 18p using a combination of cytogenetic and molecular genetic methods, including multiplex fluorescent PCR. The patient was referred for chorionic villus sampling (CVS) due to advanced maternal age and maternal anxiety. The placental karyotype was 47,XX,+mar, with the marker having the appearance of a small supernumerary isochromosome. Because differentiating between isochromosomes and other structural rearrangements is normally very difficult, a variety of genetic tests including fluorescence in situ hybridization (FISH), PCR, and multiplex fluorescent PCR were undertaken to determine chromosomal origin and copy number and, thus, allow accurate diagnosis of the corresponding syndrome. FISH determined that the marker chromosome contained chromosome 18 material. PCR of a variety of short tandem repeats (STRs) confirmed that there was at least one extra copy of the maternal 18p material. However, neither FISH nor PCR could accurately determine copy number. Multiplex fluorescent PCR (MF-PCR) of STRs simultaneously determined that: (1) the marker included 18p material; (2) the marker was maternal in origin; (3) allele copy number indicated tetrasomy; and (4) contamination of the sample could be ruled out. Results were also rapid with accurate diagnosis of the syndrome tetrasomy 18p possible within 5 hours.

Abstract
To learn more about the frequencies of congenital prothrombotic disorders in pediatric venous thromboembolism (VTE) and the outcome of this disease, we evaluated consecutive patients from 0 to 18 years with objectively diagnosed VTE at a single tertiary center over a 12-year period. We included 100 patients, with a median age at diagnosis of 1.0 year (range 2 days to 17 years). At least one underlying clinical condition was present in 96% of the patients. Factor (F)V G1691A mutation was present in 13%, FII G20210A mutation in 3%, antithrombin deficiency in 1%, protein C deficiency in 1% and protein S deficiency in 1% of the tested patients. Combined defects were present in 2.6% of the 77 patients with a complete work-up. Positive family history appeared to be the only predictor for positive testing for congenital disorders (OR 14.9, 95% CI 1.9-113). The overall mortality rate was 20%. The cumulative recurrence-free survival was 92% after 1 year of follow-up, and 82% after 7 years. The incidence and severity of the post-thrombotic syndrome was analyzed in a subgroup of 33 patients with VTE of the lower extremities. Twenty-three (70%) patients developed PTS: moderate in three and mild in 20 patients. In conclusion, congenital prothrombotic disorders seem to play a role in the development of pediatric VTE, and the risk of complications of this disease is high.

Abstract
We present the first measurement of decay amplitudes in B-->phiK* and measurements of branching fractions in B-->phiK(*) decays based on 78.1 fb(-1) of data recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB e+e- storage ring. The decay amplitudes for the different phiK*0 helicity states are measured from the angular distributions of final state particles in the transversity basis. The longitudinal and transverse complex amplitudes are |A0|2=0.43+/-0.09+/-0.04, |A(perpendicular)|2=0.41+/-0.10+/-0.04, arg((A(parallel))=-2.57+/-0.39+/-0.09, and arg((A(perpendicular))=0.48+/-0.32+/-0.06. The direct CP-violating asymmetries are found to be consistent with zero.

Abstract
OBJECTIVES To record the number of haemophilicas aged 0-18 years in the Western Cape (WC), what event led to the diagnosis, the level of clotting factor, treatment, functional status of their joints and impact of the disease on the family. DESIGN A prospective study of patients registered with the South African National Haemophilia Registry and new patients, utilising the patients' paediatricians, hospital records, patient and guardian interviews, physical examination and provincial nurse haemophilia co-ordinators. SETTING Haemophilia care centres at the three WC academic hospitals, regional hospitals and homes of patients. Two elective medical students, MHH and JJH, collected the information. SUBJECTS All boys with confirmed haemophilia A or B in the WC. OUTCOME MEASURES Events that led to diagnosis, degree of haemophilia, use of clotting factor, functional status, and effect on family. RESULTS Of 78 patients (59 haemophilia A, 19 haemophilia B) identified, 49 could be studied. Forty-three per cent had severe, 29% moderate and 22% mild disease (6% unknown). Family history was present in 49%, but led to diagnosis in only 12%. The most common first symptoms were subcutaneous and mucosal bleeding. Delay in diagnosis varied from 0 to 9 months. Twenty-nine per cent of guardians were suspected of child abuse. RSA produced clotting factor was used 'on demand' in 73% of patients, for periodic prophylaxis in 20% and as continuous prophylaxis in 7%. Joints were functionally restricted in 43% of patients. The majority of guardians (59%) said the disease had a major impact on the family. CONCLUSIONS The diagnosis of haemophilia in children with a positive family history was often delayed. Haemophilia causes significant morbidity in our patients and their families.

Abstract
A clinical, morphologic, ultrastructural, and genetic study was performed on five rough-coated dachshund semisiblings with osteogenesis imperfecta (OI). Clinical signs consisted of pain, spontaneous bone and teeth fractures, joint hyperlaxity, and reduced bone density on radiography. Primary teeth were extremely thin-walled and brittle. The hallmark of the disease was a severe osteopenia characterized by impairment of lamellar bone formation in the long bones, skull, and vertebral column. No deformity or dwarfism was present. The columns of chondrocytes and primary trabeculae in the epiphyses and metaphyses were histologically normal. An abrupt failure of secondary spongiosa and lamellar bone formation was evident in the medullary and cortical zones in all animals. The few existing trabeculae consisted of woven bone. There was no increase in the number and size of osteoclasts or lacunae. In the teeth, the dentine layers were thin and lacked a tubular pattern. Ultrastructurally, osteoid apposition on bone surfaces was reduced, and small numbers of large cytoplasmic vacuoles were present in a few osteoblasts. Molecular analyses of the collagen type I-encoding genes COL1A1 and COL1A2 revealed several nucleotide differences compared with the published canine sequences but were not significant for OI. Therefore, OI in these Dachshund litters was characterized by a severe, generalized osteopenia and dentinopenia. This pattern of reduced bone formation is suggestive of defective production of collagen type I.
