Abstract
Water retention curves are essential for understanding the hydrologic behavior of partially saturated porous media and modeling flow and transport processes within the vadose zone. We directly measured the main drying and wetting branches of the average water retention function obtained using two-dimensional neutron radiography. Flint sand columns were saturated with water and then drained and rewetted under quasi-equilibrium conditions using a hanging water column setup. Digital images (2048 by 2048 pixels) of the transmitted flux of neutrons were acquired at each imposed matric potential (∼10-15 matric potential values per experiment) at the National Institute of Standards and Technology Center for Neutron Research BT-2 neutron imaging beam line. Volumetric water contents were calculated on a pixel-by-pixel basis using Beer-Lambert's law after taking into account beam hardening and geometric corrections. To account for silica attenuation and remove scattering effects at high water contents, the volumetric water contents were normalized (to give relative saturations) by dividing the drying and wetting sequences of images by the images obtained at saturation and satiation, respectively. The resulting pixel values were then averaged and combined with information on the imposed basal matric potentials to give average water retention curves. The average relative saturations obtained by neutron radiography showed an approximate one-to-one relationship with the average values measured volumetrically using the hanging water column setup. There were no significant differences (P < 0.05) between the parameters of the van Genuchten equation fitted to the average neutron radiography data and those estimated from replicated hanging water column data. Our results indicate that neutron imaging is a very effective tool for quantifying the average water retention curve.

Abstract
AIMS To examine the reliability and validity of the Dundee Ready Educational Environment Measure (DREEM) amongst New Zealand students in the first professional year of the Bachelor of Dental Surgery (BDS) and Bachelor of Oral Health (BOH) programmes. METHOD In 2009 and 2010, students' perceptions of the educational environment were evaluated using a modified version of the 50-item DREEM, completed on the first and last day of their first professional year. Individual DREEM items' strengths and weaknesses were identified. The difference or dissonance between students' expectations and actual experience was determined by subtracting the Actual DREEM score (for each item or subscale) from the Expected DREEM score. Effect-size statistics were calculated, and internal consistency was tested using Cronbach's alpha. RESULTS Overall, 82% of 2009 and 2010 BDS and BOH students in their first professional year completed the Expected and Actual DREEM (N = 176). Both groups identified the 'overemphasis of factual learning' as an Expected and Actual aspect and 'memorising all I need to know' as an Actual aspect of the educational environment. Internal consistency was high for the overall DREEM and the BDS and BOH Expected DREEM (0.89 and 0.88, respectively) and excellent for both the BDS and BOH Actual DREEM (0.92 and 0.90, respectively). CONCLUSION Overall, students entering the courses anticipated a number of strengths and weaknesses and those expectations were relatively similar in the different programmes (BDS and BOH). The DREEM showed excellent internal consistency for the overall scores, and that for the subscale scores was generally acceptable. The study confirms the DREEM's utility for the NZ dental education environment.

Abstract
The concentration of remifentanil required for acceptable nasotracheal intubation in adults after target-controlled infusion (TCI) of propofol without neuromuscular blockade was compared with that required for orotracheal intubation. Twenty-five patients undergoing oral and maxillofacial surgery received nasotracheal intubation and 25 undergoing ear, nose and throat surgery received orotracheal intubation. Anaesthesia was induced with propofol TCI at a target effect-site concentration of 5.0 μg/ml. The 50% and 95% effective concentrations (EC(50) and EC(95), respectively) for remifentanil, calculated using isotonic regression, were 5.40 and 6.85 ng/ml, respectively, in the orotracheal group and 5.75 and 7.43 ng/ml in the nasotracheal group. The EC(50) (± SD) values for remifentanil, calculated using a modified Dixon's up-and-down method, were 6.08 ± 0.75 and 5.58 ± 0.75 ng/ml for nasotracheal and orotracheal intubation, respectively. Effect-site remifentanil concentrations did not differ significantly between the two groups of patients. Coadministration of propofol and remifentanil can provide acceptable conditions for nasotracheal intubation without neuromuscular blockade.

Abstract
OBJECTIVE To examine the efficiency of hydrogen-rich saline in the treatment of intensive noise-induced cochlear injury. MATERIALS AND METHODS Forty guinea pigs were assigned to one of four groups: HS+NOISE (i.p. injection hydrogen-rich saline), NS+NOISE (i.p. injection normal saline), NOISE ALONE (noise control), and NO TREATMENT (normal control) groups. The HS+NOISE, NS+NOISE, and NOISE ALONE groups were exposed to intensive noise (4 h at 115 dB SPL noise of 4000±100 Hz). The auditory brainstem response (ABR) was used to examine the hearing threshold in each group. Distortion product otoacoustic emission (DPOAE) was used to examine outer hair cell function. We also examined cochlear morphology to evaluate inner and outer hair cell trauma induced by noise exposure. Hydrogen-rich saline was administered twice daily for 6 days (2.5 ml/kg, i.p.) 24 h after noise exposure. RESULTS Baseline ABR thresholds and DPOAE values were normal in all groups at the measured frequencies (2, 4, 8, and 16 kHz) before noise exposure. The ABR threshold shift was 50-55 dB across the frequencies tested, and average DPOAE declined in the NOISE ALONE, NS+NOISE, and HS+NOISE groups 24 h after noise exposure. However, the changes in cochlear parameters were different between groups. The HS+NOISE group showed a significantly decreased ABR threshold value as compared with the NS+NOISE or NOISE ALONE group (P<0.01) on day 7. The mean DPOAE recovered to some extent in the three noise exposure groups, but at most frequencies the HS+NOISE group showed significantly increased DPOAE on day 7 as compared with the NS+NOISE group or NOISE ALONE group (P<0.01). Surface Corti organ preparations stained with succinate dehydrogenase (SDH) showed that most outer hair cells (OHCs) were still dropsical and a few were missing 7 days after noise exposure in the NS+NOISE group. Only a few OHCs were slightly dropsical in the HS+NOISE group. The numbers of missing hair cells 7 days after noise exposure were significantly greater in the NOISE ONLY and NS+NOISE groups than the HS+NOISE group (P<0.01). CONCLUSIONS Hydrogen-rich saline can alleviate experimental noise-induced hearing loss in guinea pigs, partially by preventing the death of cochlear hair cells after intensive noise exposure.

Abstract
OBJECTIVES To explore and compare how pre-doctoral dentistry (BDS) and oral health (BOH) students characterise their future professional work at the start and end of their first-year professional programme. MATERIALS AND METHODS All BDS and BOH students were given an anonymous survey on the first and last days of their 2009 course. Start and end surveys (ES) were completed by 75% of BDS (51) and 83% of BOH students (33). This paper examines students' responses to two questions asking them to identify a situation characterising their future professional work and a professional difficulty they would likely encounter. Student responses were analysed inductively to identify key themes and confirm each theme's 'weighting' based on frequency of mention. RESULTS Students' answers to both questions revealed eight characterisations of future professional work involving the following: restorative tasks, patient-related concerns, patient emotion and behaviour, population-level/public health concerns, disease prevention and monitoring, communication, teamwork and self-management. In ES responses, BDS students emphasised restorative tasks as central to a dentist's work, and in both surveys perceived 'dealing with patients' as a central difficulty. In contrast, BOH students' answers to both questions revealed a patient care emphasis, and in both surveys, BOH students emphasised patient-related concerns as a likely difficulty. CONCLUSION Bachelor of Dentistry students characterised their work as primarily interventive, and BOH students, as primarily patient-centred, communicative, and preventive. Whilst BDS students apparently valued restorative capabilities, BOH students valued the ability to ensure patient well-being. Further research will examine students' differing perceptions and how these change over time.

Abstract
OBJECTIVES The extent to which highly active antiretroviral therapy (HAART) affects human papillomavirus (HPV) acquisition and clearance in HIV-infected women is not well understood. We sought to describe high-risk HPV detection and clearance rates over time since HAART initiation, based on time-varying HIV viral load (VL) and CD4 T-cell count, using novel statistical methods. METHODS We conducted a retrospective analysis of data from the completed AIDS Clinical Trials Group (ACTG) A5029 study using multi-state Markov models. Two sets of high-risk HPV types from 2003 and 2009 publications were considered. RESULTS There was some evidence that VL>400 HIV-1 RNA copies/mL was marginally associated with a higher rate of HPV detection [P=0.068; hazard ratio (HR) =4.67], using the older set of high-risk HPV types. Such an association was not identified using the latest set of HPV types (P=0.343; HR=2.64). CD4 count >350 cells/μL was significantly associated with more rapid HPV clearance with both sets of HPV types (P=0.001, HR=3.93; P=0.018, HR=2.65). There was no evidence that HPV affects VL or CD4 cell count in any of the analyses. CONCLUSIONS High-risk HPV types vary among studies and can affect the results of analyses. Use of HAART to improve CD4 cell count may have an impact on the control of HPV infection. The decrease in VL may also have an effect, although to a lesser degree.

Abstract
Haemodynamic changes occurring during heart displacement, using moist laparotomy pads placed behind the heart (PAD group, n = 26) or deep pericardial traction sutures (DPS group, n = 25) to facilitate exposure of the left anterior descending artery during off-pump coronary artery bypass surgery, were compared. Haemodynamic variables were assessed before and 10 min after displacement of the heart. The central venous pressure, mean pulmonary artery pressure and pulmonary capillary wedge pressure increased in both groups. After heart displacement in the PAD group, the cardiac index, stroke volume index, mixed venous oxygen saturation, right ventricular ejection fraction and left ventricular stroke work index decreased significantly, and the systemic vascular resistance and pulmonary vascular resistance increased significantly; these parameters remained unchanged in the DPS group. It was concluded that displacement of the heart using moist laparotomy pads caused significant haemodynamic derangement compared with that caused by deep pericardial traction sutures.

Abstract
Thioredoxin peroxidases (Tpxs) play important roles in protecting organisms against the toxicity of reactive oxygen species (ROS) and regulating intracellular signal transduction. In the present study, we cloned the full cDNA of Tpx1 encoding a 195-amino acid protein from Apis cerana cerana (Acc). Based on the genomic DNA sequence, a 1442-bp 5'-flanking region was obtained, and the putative transcription factor binding sites were predicted. Quantitative PCR analysis showed that AccTpx1 was highly expressed in thorax and that the AccTpx1 transcript reached its highest level in two-week-old adult worker honeybees. Moreover, expression of the AccTpx1 transcript was increased by various abiotic stresses, such as ultraviolet light, HgCl(2) , and insecticide treatments. In addition, the recombinant AccTpx1 protein exhibited antioxidant activity; it removed hydrogen peroxide and protected DNA. These results suggest that AccTpx1 plays an important role in protecting honeybees from oxidative injury and may act in extending the lifespan of them.

Abstract
We evaluated immunologic predictors of response to HBV vaccine administered in the presence or absence of GM-CSF in HIV infected individuals. We measured peripheral blood hematopoietic progenitor, monocyte and myeloid-derived suppressor cell (MDSC) frequencies, and expression of GMCSF receptor on monocytes and MDSCs, at baseline and 4weeks after immunization in relation to antibody response. We observed higher baseline progenitor and lower monocyte frequencies among week 16 antibody responders. Week 4 decline in MDSC frequency was associated with week 16 antibody response, while administration of GM-CSF was associated with preservation of these cells. No significant differences in GM-CSF receptor expression were observed in the presence vs. absence of GM-CSF. These findings are consistent with a positive role of progenitor cells and a potential negative role of monocytes in vaccine response. Additionally, GM-CSF augmented the preservation of peripheral blood MDSC, which may contribute to the lack of improved vaccine responses.

Abstract
Oligodendrocyte-derived myelin retards the ability of CNS axons to regenerate following transection. The intrinsic response of CNS axons to an axotomy insult may be vastly different in the absence of myelin. However, the paucity of adequate experimental models has limited detailed investigation of cellular behaviour following axon transection in an unmyelinated CNS environment. In this study we perform laser-induced axotomy of the porcine retinal ganglion cell axon, a physiologically unmyelinated, mature CNS axon that is structurally similar to humans to infer knowledge about axonal behaviour in the absence of myelin. Axotomy-induced changes to the neuronal cytoskeleton and supporting astrocytes during the early stages after transection are delineated by examining the sequence of neurofilament subunit, microtubule (TUB), microtubule associated protein (MAP), glial fibrillary acidic protein (GFAP) and terminal deoxynucleotidyl transferase biotin-dUTP nick end labelling (TUNEL) modification. Axonal transection induced an increase in the expression of neurofilament light at regions within, and immediately adjacent to, sites of axotomy. Other neurofilament subunits were not altered at sites of transection. Unlike myelinated axons where an increase in GFAP staining within hypertrophic glial scars have been shown to inhibit axonal repair we demonstrate a decrease in GFAP staining within regions of increased or preserved neurofilament expression. The behaviour of TUB and MAP proteins following transection of unmyelinated CNS axons are similar to what has previously been described in myelinated CNS axons. This study provides fundamental insights into astrocyte and axonal behaviour acutely after axotomy and demonstrates a series of degenerative events in unmyelinated CNS axons, which in comparison to prior reports are different to myelinated CNS axons. The findings of this report have relevance to understanding pathogenic mechanisms underlying neuro-degeneration in the CNS.

Abstract
BACKGROUND Infraclavicular approach of the subclavian veins is commonly used for central venous access. However, aberrant catheter tip locations are frequently quoted for this approach. It was hypothesized that with the shoulder pulled downwards, the angle between the internal jugular and subclavian veins may increase, directing subclavian catheters into the internal jugular vein. This prospective study assessed the influence of the shoulder position on proper placement of right infraclavicular subclavian catheters. METHODS Patients who required subclavian central venous catheterization for major neurosurgical and thoracic procedures were randomly divided into two groups: neutral (n=180) vs lowered (n=181) shoulder position. The right shoulder was placed and maintained in the neutral or lowered position during venipuncture and guidewire insertion. Postoperative chest radiographs were obtained to identify the location of catheter tips. RESULTS There were no differences in gender, age, body weight, and height between the two groups. There were five failures in the neutral position [5/180 (2.8%)] and eight failures in the lowered shoulder position [8/181 (4.0%)] (P=NS). The occurrence of immediate complications such as pneumothorax or arterial puncture was not different. Aberrant placement of the catheter tips was more frequent in the lowered shoulder position [2/173 (1.2%) vs 14/173 (8.1%)] (P<0.01). CONCLUSIONS The neutral shoulder position minimizes the number of needle passes and the incidence of catheter misplacement during the infraclavicular approach of the right subclavian vein catheterization.

Abstract
BACKGROUND Gastrointestinal inflammation significantly affects the electrical excitability of smooth muscle cells. Considerable progress over the last few years have been made to establish the mechanisms by which ion channel function is altered in the setting of gastrointestinal inflammation. Details have begun to emerge on the molecular basis by which ion channel function may be regulated in smooth muscle following inflammation. These include changes in protein and gene expression of the smooth muscle isoform of L-type Ca(2+) channels and ATP-sensitive K(+) channels. Recent attention has also focused on post-translational modifications as a primary means of altering ion channel function in the absence of changes in protein/gene expression. Protein phosphorylation of serine/theronine or tyrosine residues, cysteine thiol modifications, and tyrosine nitration are potential mechanisms affected by oxidative/nitrosative stress that alter the gating kinetics of ion channels. Collectively, these findings suggest that inflammation results in electrical remodeling of smooth muscle cells in addition to structural remodeling. PURPOSE The purpose of this review is to synthesize our current understanding regarding molecular mechanisms that result in altered ion channel function during gastrointestinal inflammation and to address potential areas that can lead to targeted new therapies.

Abstract
HIV-infected persons are at risk for HBV co-infection which is associated with increased morbidity and mortality. Unfortunately, protective immunity following HBV vaccination in HIV-infected persons is poor. This randomized, phase II, open-label study aimed to evaluate efficacy and safety of 40 mcg HBV vaccine with or without 250 mcg GM-CSF administered at day 0, weeks 4 and 12. HIV-infected individuals >or=18 years of age, CD4 count >or=200 cells/mm(3), seronegative for HBV and HCV, and naïve to HBV vaccination were eligible. Primary endpoints were quantitative HBsAb titers and adverse events. The study enrolled 48 subjects. Median age and baseline CD4 were 41 years and 446 cells/mm(3), 37 were on ART, and 26 subjects had undetectable VL. Vaccination was well tolerated. Seven subjects in the GM-CSF arm reported transient grade >or=2 signs/symptoms (six grade 2, one grade 3), mostly aches and nausea. GM-CSF had no significant effect on VL or CD4. Four weeks after vaccination, 26 subjects (59%) developed a protective antibody response (HBsAb >or=10 mIU/mL; 52% in the GM-CSF arm and 65% in the control arm) without improved Ab titer in the GM-CSF vs. control arm (median 11 mIU/mL vs. 92 mIU/mL, respectively). Response was more frequent in those with CD4 >or=350 cells/mm(3) (64%) than with CD4 <350 cells/mm(3) (50%), though not statistically significant. GM-CSF as an adjuvant did not improve the Ab titer or the development of protective immunity to HBV vaccination in those receiving an accelerated vaccine schedule. Given the common routes of transmission for HIV and HBV, additional HBV vaccine research is warranted.

Abstract
BACKGROUND AND PURPOSE Excitation-transcriptional coupling involves communication between plasma membrane ion channels and gene expression in the nucleus. Calcium influx through L-type Ca(2+) channels induces phosphorylation of the transcription factor, cyclic-AMP response element binding protein (CREB) and downstream activation of the cyclic-AMP response element (CRE) promoter regions. Tyrosine nitration of Ca(2+) channels attenuates interactions with c-Src kinase, decreasing Ca(2+) channel currents and smooth muscle contraction during colonic inflammation. In this study we examined the effect of tyrosine nitration and colonic inflammation on Ca(2+) channel mediated phosphorylation of CREB and CRE activation. EXPERIMENTAL APPROACH CREB and phospho-CREB were detected by Western blots and CRE activation measured by dual luciferase assay. Chinese hamster ovary (CHO) cells were transfected with hCa(v)1.2b and hCa(v)1.2b c-terminal mutants. Colonic inflammation was induced by intracolonic instillation of 2,4,6 trinitrobenzene sulphonic acid in mouse colon. KEY RESULTS In hCa(v)1.2b transfected CHO cells and in native colonic smooth muscle, depolarization with 80 mM KCl induced CREB phosphorylation (pCREB). Treatment with peroxynitrite inhibited KCl-induced pCREB. Following experimental colitis, KCl-induced CREB phosphorylation was abolished in smooth muscle, concomitant with tyrosine nitration of Ca(2+) channels. Depolarization increased CRE activation in hCa(v)1.2b CHO cells by 2.35 fold which was blocked by nifedipine and by protein nitration of Ca(2+) channels with peroxynitrite. The Src-kinase inhibitor, PP2, blocked depolarization-induced CRE activation. Mutation of the C-terminus tyrosine residue, Y2134F, but not Y1861F, blocked CRE activation. CONCLUSIONS AND IMPLICATIONS Post-translational modification of Ca(2+) channels due to tyrosine nitration modified excitation-transcriptional coupling in colonic inflammation.

Abstract
The AIDS epidemic has contributed to a drastic increase in the number of orphans in Zimbabwe. Orphans (whether orphaned by AIDS or other causes) have been shown to have economic and educational disadvantages as well as poor reproductive health outcomes. We recruited a convenience sample of 200 girls in a peri-urban area of Zimbabwe to examine the impact of orphan status (compared to non-orphans) on household composition, education, risk behaviour, pregnancy and prevalent HIV and HSV-2 infection. In our population, maternal orphans were more likely to be in households headed by themselves or a sibling, to be sexually active, to have had an STI, to have been pregnant and to be infected with HIV. Paternal orphans were more likely to have ever been homeless and to be out of school. Our findings suggest that maternal care and support is important for HIV prevention. This finding corroborates previous research in Zimbabwe and has implications for intervention strategies among orphan girls.

Abstract
Papillary endolymphatic sac tumours (ELSTs) are rare lesions of the temporal bone often confused with other more common entities. However, the radiologic differentiation is important for both surgical planning and also to alert the pathologist as regards the true origin. We present a case of a large ELST with some specific radiological findings.

Abstract
OBJECTIVES Ribavirin (RBV) is used for the treatment of hepatitis C virus (HCV) infection in subjects with HIV-1 infection who may require antiretroviral treatment (ART) with nucleoside reverse transcriptase inhibitors including zidovudine (ZDV). We sought to investigate the potential antagonism between RBV and ZDV by evaluating the impact of RBV on the formation of intracellular ZDV triphosphate (TP) in HIV-infected patients receiving ZDV who were treated for HCV infection. METHODS Serial plasma and intracellular ZDV TP pharmacokinetics (PK) were determined in 14 subjects at entry (within 2 weeks prior to RBV administration) and at 8 weeks following initiation of RBV. Intracellular ZDV TP in peripheral blood mononuclear cells (PBMC) was quantified by a validated cartridge/liquid chromatography/tandem mass spectrometry method. PK exposure was estimated from the steady-state area under the concentration vs time curve (AUC(0-12 h)) in plasma and PBMC. RESULTS Ribavirin did not have a statistically significant impact on ZDV TP AUC(0-12 h), plasma ZDV AUC(0-12 h) or the ratio of ZDV TP AUC(0-12 h) to plasma ZDV AUC(0-12 h), although there was a trend towards an increase post-RBV ratio compared with pre-RBV. There was extensive variability in the ZDV TP AUC(0-12 h). CONCLUSIONS Ribavirin did not inhibit formation of ZDV TP in PBMC in 14 patients receiving ZDV as part of ART and RBV-based HCV therapy for 8 weeks. These results are consistent with those of a previously published limited study in seven subjects. These PK findings should be weighed carefully against emerging clinical reports of significant anaemia associated with combination ZDV and high-dose RBV therapy.

Abstract
Young people (16-25 years) are a target group for the prevention of Chlamydia trachomatis in the Australian national STI strategy. This study is a randomized controlled trial of an innovative internet-based intervention which aims to increase Chlamydia testing and treatment among at risk young people living in Australia. Study participation is via a website developed in consultation with young people and linked to an evaluated health promotion website. Young people in the intervention group receive personalised, confidential emails from a nurse or doctor while those in the control group receive automated emails. Follow up at 6 months will measure self-reported Chlamydia testing and other outcomes. By 5 June 2007, 359 young people of a target sample of 1000 were enrolled (83% female). Mean age is 20 years (range 16-25). Participants reside across all states and territories. Thirty percent of participants in the intervention group are in active email dialogue with the research nurse, e.g. “The research and...site was...really good,...it's kinda scared me into getting a test and just to get over the embarrassment... will the test be able to be part of just a normal appointment?” Zero participants in the control group have responded to the automated email. Baseline data and examples of the email interaction will be presented.

Abstract
INTRODUCTION A randomized, double-blind, prospective, 24-week clinical trial was performed to evaluate the effects of a combinative agent, Maxmarvil, of calcitriol (0.5 mug) and alendronate (5 mg) on bone metabolism in postmenopausal women. METHODS A total of 217 postmenopausal women with osteoporosis were enrolled; 199 patients were randomly assigned to one of two treatment groups (Maxmarvil group or alfacalcidol group). None of the patients were vitamin-D-deficient, as assessed by serum 25-hydroxyvitamin D (25(OH)D), nor had they received any drugs affecting bone metabolism before enrollment. Bone mineral densities (BMD) of L1-L4 and the femur were measured by dual-energy X-ray absorptiometry (DXA) at the initial assessment and after 6 months of treatment. Serum biochemical assays, including serum calcium, 24-h urinary calcium excretion, and bone turnover markers (both bone-specific alkaline phosphatase [bsALP] and urine N-telopeptide [NTx]), were performed at the baseline and after 3 and 6 months of treatment. RESULTS In the Maxmarvil group, the BMD of the lumbar spine increased up to 2.42+/-0.5% from the baseline after 6 months (p<0.05). On the other hand, the change in BMD in the alfacalcidol group was 0.28+/-0.5% after 6 months. There was no significant difference in femoral BMD between the two groups. The levels of bsALP and NTx were significantly lower in the Maxmarvil group than in the alfacalcidol group (-22.04+/-3.9% vs. -11.42+/-2.8% [p<0.05] and -25.46+/-5.2% vs. 1.24+/-6.2% [p<0.001], respectively). Interestingly, there was a significantly smaller amount of 24-h urinary calcium in the Maxmarvil group (p<0.05). CONCLUSIONS Our study demonstrates that a combination of calcitriol and alendronate is quite effective in preventing bone loss, with the advantage of lesser hypercalciuric effect of calcitriol in the postmenopausal osteoporotic women.
