Abstract
The electromagnetic form factors of the proton and neutron encode information on the spatial structure of their charge and magnetization distributions. While measurements of the proton are relatively straightforward, the lack of a free neutron target makes measurements of the neutron's electromagnetic structure more challenging and more sensitive to experimental or model-dependent uncertainties. Various experiments have attempted to extract the neutron form factors from scattering from the neutron in deuterium, with different techniques providing different, and sometimes large, systematic uncertainties. We present results from a novel measurement of the neutron magnetic form factor using quasielastic scattering from the mirror nuclei ^{3}H and ^{3}He, where the nuclear effects are larger than for deuterium but expected to largely cancel in the cross-section ratios. We extracted values of the neutron magnetic form factor for low-to-modest momentum transfer, 0.6

Abstract
PURPOSE Physical therapy (PT) and rehabilitation are widely utilized in a variety of disease processes to improve function, return to activities of daily living (ADLs), and promote overall recovery. However, hernia repair has struggled to adopt this practice despite operations occurring in one of the most dynamic parts of the body - the abdominal core. This study sought to understand perspectives and perceived barriers regarding the incorporation of PT and rehabilitation in hernia care. METHODS A standardized rehabilitation protocol was developed by the Abdominal Core Health Quality Collaborative (ACHQC), a national quality improvement initiative specific to hernia disease, and launched in 2019. Empiric data from the ACHQC was then obtained to describe preliminary utilization. A prospective electronic survey was then deployed to all surgeons participating in the ACHQC to aid in interpreting the identified trends. The survey included questions regarding the current use of PT in their practice, as well as further opinions on the functionality, benefit, and barriers to its use. RESULTS We identified 1,544 patients who were listed as receiving some form of postoperative rehabilitation, of which 992 (64.2%) had a primary diagnosis of ventral hernia and 552 (35.8%) had an inguinal hernia. Among patients who had a ventral hernia, 863 (87.0%) received self-directed rehabilitation exercises compared to 488 (88.4%) of inguinal hernia patients. The subsequent survey exploring these trends was completed by 46 ACHQC surgeons (10.2%). More than half (52%) reported using PT for hernia patients, primarily in abdominal wall reconstruction cases (92%). Of those who did not report using PT, 50% cited unknown clinical benefit and another 27% cited unknown PT resources. PT utilization was typically concentrated to the postoperative period (58%), while 42% reported also using it preoperatively. Despite 72% of respondents citing a perceived benefit of PT in hernia patients, overall use of PT was primarily reported as 'occasional' by 42%, with another 27% reporting 'rarely.' Perceived benefits of PT included increased core strength, stability, mobility, patient satisfaction, education, independence, earlier return to work and ADLs, overall improved recovery, and decreased risk of postoperative issues. Reported barriers to implementing PT in practice or adapting the ACHQC Rehabilitation Protocol included lack of education, lack of evidence of clinical benefit, and difficulties operationalizing the protocol. CONCLUSION A national survey of hernia surgeons demonstrated willingness to adopt PT and rehabilitation protocols in their clinical practices and noted a high perceived benefit to patients. However, lack of education and evidence regarding the protocol may represent important barriers to overcome in widely disseminating these resources to patients. These gaps can be addressed through dedicated educational venues and additional studies establishing PT and rehabilitation as critical future adjuncts for the recovery of hernia repair patients.

Abstract
The ratio of the nucleon F_{2} structure functions, F_{2}^{n}/F_{2}^{p}, is determined by the MARATHON experiment from measurements of deep inelastic scattering of electrons from ^{3}H and ^{3}He nuclei. The experiment was performed in the Hall A Facility of Jefferson Lab using two high-resolution spectrometers for electron detection, and a cryogenic target system which included a low-activity tritium cell. The data analysis used a novel technique exploiting the mirror symmetry of the two nuclei, which essentially eliminates many theoretical uncertainties in the extraction of the ratio. The results, which cover the Bjorken scaling variable range 0.19<x<0.83, represent a significant improvement compared to previous SLAC and Jefferson Lab measurements for the ratio. They are compared to recent theoretical calculations and empirical determinations of the F_{2}^{n}/F_{2}^{p} ratio.

Abstract
We report the first measurement of the (e,e^{'}p) three-body breakup reaction cross sections in helium-3 (^{3}He) and tritium (^{3}H) at large momentum transfer [⟨Q^{2}⟩≈1.9 (GeV/c)^{2}] and x_{B}>1 kinematics, where the cross section should be sensitive to quasielastic (QE) scattering from single nucleons. The data cover missing momenta 40≤p_{miss}≤500 MeV/c that, in the QE limit with no rescattering, equals the initial momentum of the probed nucleon. The measured cross sections are compared with state-of-the-art ab initio calculations. Overall good agreement, within ±20%, is observed between data and calculations for the full p_{miss} range for ^{3}H and for 100≤p_{miss}≤350 MeV/c for ^{3}He. Including the effects of rescattering of the outgoing nucleon improves agreement with the data at p_{miss}>250 MeV/c and suggests contributions from charge-exchange (SCX) rescattering. The isoscalar sum of ^{3}He plus ^{3}H, which is largely insensitive to SCX, is described by calculations to within the accuracy of the data over the entire p_{miss} range. This validates current models of the ground state of the three-nucleon system up to very high initial nucleon momenta of 500 MeV/c.

Abstract
PURPOSE Unlike routine ventral hernia repair, abdominal wall reconstruction (AWR) can results in large pieces of mesh and extensive manipulation of the intra-abdominal contents, rendering subsequent laparoscopic cholecystectomy challenging. This study addresses the additional wound morbidity of concomitant cholecystectomy. METHODS The Americas Hernia Society Quality Collaborative (AHSQC) was retrospectively reviewed and logistic regression modeling was used to control for multiple covariates. Patients that underwent open AWR with cholecystectomy were compared to a similar group of patients undergoing uncomplicated, open, clean, AWR alone. RESULTS 130 patients undergoing concomitant cholecystectomy were compared to a control group of 6440 patients. The addition of a cholecystectomy did not cause a significant change in wound morbidity (SSI: p = 0.16; SSOPI: p = 0.65). CONCLUSIONS This study noted that a concomitant cholecystectomy does not increase the wound morbidity as compared to an uncomplicated, clean, AWR. This provides support for consideration of routine cholecystectomy in patients with cholelithiasis undergoing AWR.

Abstract
A line VISAR (Velocity Interferometer System for Any Reflector) has been designed and commissioned at the Sandia National Laboratory's Z-machine. The instrument consists of an F/2 collection system, beam transport, and an interferometer table that contains two Mach-Zehnder type interferometers and an eight channel Gated Optical Imaging (GOI) system. The VISAR probe laser operates at the 532 nm wavelength, and the GOI bandpass is 540-600 nm. The output of each interferometer is passed to an optical streak camera with four selectable sweep speeds. The system is designed with three interchangeable optics modules to select a full field of view of 1 mm, 2 mm, or 4 mm. The optical beam transport system connects the target image plane to the interferometers and the gated optical imagers. The target is integrated into a sacrificial final optics assembly that is integral to the transport beamline.

Abstract
PURPOSE Elective repair of large incisional hernias using posterior component separation with transversus abdominis release (TAR) has acceptable wound morbidity and long-term recurrence rates. The outcomes of using this reconstructive technique in the non-elective setting remains unknown. We aim to report 30-day outcomes of TAR in non-elective settings. METHODS All patients undergoing open TAR in non-elective settings were identified within the Americas Hernia Society Quality Collaborative (AHSQC). A retrospective review was conducted and outcomes of interest were 30-day Surgical Site Infections (SSI), Surgical Site Occurrences (SSO), SSOs requiring procedural intervention (SSOPI), medical complications, and unplanned readmissions and reoperations. RESULTS Fifty-nine patients met inclusion criteria. Mean BMI was 36.6 ± 8.9 kg/m2 and mean hernia width was 14.4 ± 7.2 cm. Forty (67.8%) were recurrent hernias. Pain (88%) and bowel obstruction (79.7%) were the most frequent indications for surgery. Surgical field was classified as clean in 69.5% of cases, with an 88% use of permanent synthetic mesh and fascial closure achieved in 93.2% of cases. There were 15 (25.4%) total wound events, 8 (13.6%) were SSIs. There were 8 (13.6%) SSOPIs, 6 of which were wound opening, 1 wound debridement, and 1 percutaneous drainage. At least one wound or medical complication was reported for 37% of the patients. There were no mortalities. CONCLUSION Not surprisingly, TAR in the non-elective setting is associated with increased wound morbidity requiring procedural interventions and reoperations compared to what has previously been reported for elective cases. The long-term consequences of this wound morbidity with regard to hernia recurrence are as of yet unknown.

Abstract
AIM To study the influence of patient characteristics and unit ergonomics and human factors on the time to initiation of CPR. METHODS A single center study of children, 0 to 21 years old, admitted to an ICU who experienced cardiopulmonary arrest (CPA) requiring >1 min of chest compressions. Time of CPA was determined by analysis of continuous ECG, plethysmography, arterial blood pressure, and end-tidal CO2 (EtCO2) waveforms. Initiation of CPR was identified by the onset of cyclic artifact in the ECG waveform. Patient characteristics and unit ergonomics and human factors were examined including CPA cause, identification on the High-Risk Checklist (HRC), existing monitoring, ICU type, time of day, nursing shift change, and outcome. RESULTS The median time from CPA to initiation of CPR was 50.5 s (IQR 26.5 to 127.5) in 36 CPAs. Forty-seven percent of patients experienced time from CPA to initiation of CPR of >1 min. There was no difference in CPA cause, ICU type, time of day, or nursing shift change. CONCLUSION Nearly half of pediatric patients who experienced CPA in an ICU setting did not meet AHA guidelines for early initiation of CPR. This is an opportunity to study the recognition phase of CPA using continuous monitoring data with the aim of improving the understanding of and factors contributing to delays in initiation of CPR.

Abstract
Abstract
Background: Advanced breast cancer (BC) and endometrial cancer (EC) have limited treatment options with no treatments improving survival. ONC201 is the founding member of a novel class of anticancer drugs called impiridones. The drug is orally bioavailable and crosses the blood brain barrier. Preclinical studies have demonstrated that ONC201 selectively kills various cancer cells, including all subtypes of BC and EC, while having little effect on normal cells. An on-going Phase 1 study of ONC201 has demonstrated clinical benefit in some solid tumors, including EC and glioblastomas.
Trial Design: Phase 2 single arm study of ONC201 with 3 cohorts: Cohort 1, female and male hormone receptor positive breast cancer (HR+BC); Cohort 2, female and male triple negative breast cancer (TNBC); and Cohort 3, EC. All patients will receive ONC201 at the recommended Phase 2 dose of 625mg by mouth q7 days (1 cycle = 28 days). Patients will undergo a baseline biopsy as well as a biopsy after 5 doses of ONC201 (C2D2). Patients will be evaluated for response every two cycles (8 weeks) by RECIST 1.1.
Eligibility Criteria: Measurable disease with >1 biopsiable lesion, willing to undergo biopsies. Cohort 1 (HR+BC) requires prior treatment with >2 lines of hormonal treatment. No prior treatment required for the other cohorts. Patients must have ECOG 0-1 and adequate organ function. Patients with asymptomatic or brain metastases treated > 4 weeks from study entry are eligible. Exclusion criteria include: symptomatic CNS metastases, radiotherapy ≤ 4 weeks from study entry, HIV, Hepatitis B or Hepatitis C.
Specific Aims: Primary objectives for this study are progression free survival (PFS) at 8 months for Cohort 1 (HR+BC) and overall response rate (ORR) for Cohorts 2 and 3 (TNBC and EC). Secondary objectives include safety, clinical benefit rate (CBR = partial response + complete response + stable disease), and overall survival.
Statistical Methods: This study has been designed to pause prior to full accrual to allow for evaluation of futility prior to proceeding to full accrual. In Cohort 1, if >1 of 5 patients is progression-free at 8 months, then we will recruit up to 24 patients. In Cohort 2, if >2 of 10 patients has clinical benefit then we will recruit up to 29 patients. For Cohort 3, if 1 of 13 patients has clinical benefit, then we will recruit up to 25 patients. Additional evaluations of tumor or blood samples performed will be done in an exploratory fashion, with results presented without any formal adjustment for multiple comparisons.
Target Accrual: 24 patients with HR+BC, 29 patients with TNBC, and 25 patients with EC.This trial will open Summer 2017 at the National Institutes of Health (Bethesda, MD).

Abstract
The charge and magnetic form factors, F_{C} and F_{M}, respectively, of ^{3}He are extracted in the kinematic range 25 fm^{-2}≤Q^{2}≤61 fm^{-2} from elastic electron scattering by detecting ^{3}He recoil nuclei and scattered electrons in coincidence with the two High Resolution Spectrometers of the Hall A Facility at Jefferson Lab. The measurements find evidence for the existence of a second diffraction minimum for the magnetic form factor at Q^{2}=49.3 fm^{-2} and for the charge form factor at Q^{2}=62.0 fm^{-2}. Both minima are predicted to exist in the Q^{2} range accessible by this Jefferson Lab experiment. The data are in qualitative agreement with theoretical calculations based on realistic interactions and accurate methods to solve the three-body nuclear problem.

Abstract
OBJECTIVES We used objective oral health screening and survey data to explore individual-, psychosocial-, and community-level predictors of oral health status in a statewide population of adults. METHODS We examined oral health status in a sample of 1453 adult Wisconsin residents who participated in the Survey of the Health of Wisconsin Oral Health Screening project, conducted with the Wisconsin Department of Health Services during 2010. RESULTS We found significant disparities in oral health status across all individual-, psychosocial-, and community-level predictors. More than 15% of participants had untreated cavities, and 20% did not receive needed oral health care. Individuals who self-reported unmet need for dental care were 4 times as likely to have untreated cavities as were those who did not report such a need, after controlling for sociodemographic and behavioral factors. CONCLUSIONS Our results suggested that costs were a primary predictor of access to care and poor oral health status. The results underscored the role that primary care, in conjunction with dental health care providers, could play in promoting oral health care, particularly in reducing barriers (e.g., the costs associated with unmet dental care) and promoting preventive health behaviors (e.g., teeth brushing).

Abstract
Without applying an a priori bias for species boundaries, specimen identities in the plant-parasitic nematode genus Mesocriconema were evaluated by examining mitochondrial COI nucleotide sequences, morphology, and biogeography. A total of 242 specimens that morphologically conformed to the genus were individually photographed, measured, and amplified by a PCR primer set to preserve the linkage between specimen morphology and a specific DNA barcode sequence. Specimens were extracted from soil samples representing 45 locations across 23 ecoregions in North America. Dendrograms constructed by neighbor-joining, maximum likelihood, and Bayesian Inference using a 721-bp COI barcode were used to group COI haplotypes. Each tree-building approach resulted in 24 major haplotype groups within the dataset. The distinctiveness of these groups was evaluated by node support, genetic distance, absence of intermediates, and several measures of distinctiveness included in software used for the exploration of species boundaries. Five of the 24 COI haplotype groups corresponded to morphologically characterized, Linnaean species. Morphospecies conforming to M. discus, Discocriconemella inarata, M. rusticum, M. onoense, and M. kirjanovae were represented by groups composed of multiple closely related or identical COI haplotypes. In other cases, morphospecies names could be equally applied to multiple haplotype groups that were genetically distant from each other. Identification based on morphology alone resulted in M. curvatum and M. ornatum species designations applied to seven and three groups, respectively. Morphological characters typically used for species level identification were demonstrably variable within haplotype groups, suggesting caution in assigning species names based on published compendia that solely consider morphological characters. Morphospecies classified as M. xenoplax formed a monophyletic group composed of seven genetically distinct COI subgroups. The species Discocriconemella inarata is transferred to Mesocriconema inaratum based on its phylogenetic position on the COI tree as well as previous phylogenetic analyses using 18S, ITS1, and cytochrome b nucleotide sequences. This study indicates that some of the species considered cosmopolitan in their distribution are actually multispecies polyphyletic groupings and an accurate assessment of Mesocriconema species distributions will benefit from molecular determination of haplotype relationships. The groups revealed by COI analysis should provide a useful framework for the evaluation of additional Mesocriconema species and will improve the reliability of designating taxonomic units in studies of nematode biodiversity.

Abstract
The charge form factor of 4He has been extracted in the range 29 fm(-2) ≤ Q2 ≤ 77 fm(-2) from elastic electron scattering, detecting 4He recoil nuclei and electrons in coincidence with the high resolution spectrometers of the Hall A Facility of Jefferson Lab. The measurements have uncovered a second diffraction minimum for the form factor, which was predicted in the Q2 range of this experiment. The data are in qualitative agreement with theoretical calculations based on realistic interactions and accurate methods to solve the few-body problem.

Abstract
Most monoclonal antibodies (mAbs) generated from humans infected or vaccinated with the 2009 pandemic H1N1 (pdmH1N1) influenza virus targeted the hemagglutinin (HA) stem. These anti-HA stem mAbs mostly used IGHV1-69 and bound readily to epitopes on the conventional seasonal influenza and pdmH1N1 vaccines. The anti-HA stem mAbs neutralized pdmH1N1, seasonal influenza H1N1 and avian H5N1 influenza viruses by inhibiting HA-mediated fusion of membranes and protected against and treated heterologous lethal infections in mice with H5N1 influenza virus. This demonstrated that therapeutic mAbs could be generated a few months after the new virus emerged. Human immunization with the pdmH1N1 vaccine induced circulating antibodies that when passively transferred, protected mice from lethal, heterologous H5N1 influenza infections. We observed that the dominant heterosubtypic antibody response against the HA stem correlated with the relative absence of memory B cells against the HA head of pdmH1N1, thus enabling the rare heterosubtypic memory B cells induced by seasonal influenza and specific for conserved sites on the HA stem to compete for T-cell help. These results support the notion that broadly protective antibodies against influenza would be induced by successive vaccination with conventional influenza vaccines based on subtypes of HA in viruses not circulating in humans.

Abstract
333 Background: Primary pancreatic small cell carcinoma (SCC) is rare, with just over 30 cases reported in the literature. Only 7 of these patients underwent surgical resection with a median survival of 6 months. Prognosis of SCC is therefore considered to be poor, and the role of adjuvant therapy is uncertain. Here we report two institutions' experience with resectable pancreatic SCC. Methods: Six patients with pancreatic SCC at the Johns Hopkins Hospital (4 patients) and the Mayo Clinic (2 patients) were identified from prospectively collected pancreatic cancer databases and re-reviewed by pathology. All six patients underwent a pancreaticoduodenectomy. Clinicopathologic data was analyzed, and the literature on pancreatic SCC was reviewed. Results: Median age at diagnosis was 50 years (range 27-60). Half of the patients were male, and half were known smokers. All six masses were limited to the pancreatic head. Median tumor size was 3 cm, and all cases had positive lymph nodes except for one patient who only had five nodes sampled. There was no perioperative mortality, although three patients had postoperative complications. All six patients received adjuvant chemotherapy therapy, five of whom were given cisplatin and etoposide. Of these five patients, three were known to have received radiation, while the remaining two had a plan for radiation at an outside facility. Median survival was 20 months with a range of 9-173 months. The patient who lived for 9 months received chemotherapy only, while the patient who lived for 173 months was given chemoradiation with cisplatin and etoposide and represents the longest reported survival time from pancreatic SCC to date. Conclusions: Pancreatic SCC is an extremely rare form of cancer with a poor prognosis. Patients in this surgical series showed improved survival rates when compared to prior experiences with both resected and unresectable cases. Cisplatin and etoposide appears to be the preferred chemotherapy regimen, although its efficacy remains uncertain, as does the role of combined modality treatment with radiation. No significant financial relationships to disclose.

Abstract
The Afrotropical mosquito Anopheles gambiae sensu stricto, a major vector of malaria, is currently undergoing speciation into the M and S molecular forms. These forms have diverged in larval ecology and reproductive behavior through unknown genetic mechanisms, despite considerable levels of hybridization. Previous genome-wide scans using gene-based microarrays uncovered divergence between M and S that was largely confined to gene-poor pericentromeric regions, prompting a speciation-with-ongoing-gene-flow model that implicated only about 3% of the genome near centromeres in the speciation process. Here, based on the complete M and S genome sequences, we report widespread and heterogeneous genomic divergence inconsistent with appreciable levels of interform gene flow, suggesting a more advanced speciation process and greater challenges to identify genes critical to initiating that process.

Abstract
This systematic literature review has shown that patients experiencing hip fracture after low-impact trauma are at considerable excess risk for death compared with nonhip fracture/community control populations. The increased mortality risk may persist for several years thereafter, highlighting the need for interventions to reduce this risk.Patients experiencing hip fracture after low-impact trauma are at considerable risk for subsequent osteoporotic fractures and premature death. We conducted a systematic review of the literature to identify all studies that reported unadjusted and excess mortality rates for hip fracture. Although a lack of consistent study design precluded any formal meta-analysis or pooled analysis of the data, we have shown that hip fracture is associated with excess mortality (over and above mortality rates in nonhip fracture/community control populations) during the first year after fracture ranging from 8.4% to 36%. In the identified studies, individuals experienced an increased relative risk for mortality following hip fracture that was at least double that for the age-matched control population, became less pronounced with advancing age, was higher among men than women regardless of age, was highest in the days and weeks following the index fracture, and remained elevated for months and perhaps even years following the index fracture. These observations show that patients are at increased risk for premature death for many years after a fragility-related hip fracture and highlight the need to identify those patients who are candidates for interventions to reduce their risk.

Abstract
BACKGROUND Osteoporotic fractures are a substantial public health burden worldwide. Evidence from studies show that treatments, such as bisphosphonates, which reduce the risk of fractures when taken regularly and long term, are being used irregularly and suboptimally. The objective of this study was to quantify the additional number of hip fractures prevented by improving persistence and compliance with bisphosphonates. METHODS The study population included patients prescribed alendronate or risedronate in the UK General Practice Research Database. Individualized probabilities of fracture and death during bisphosphonate therapy and of treatment persistence and compliance were estimated by age, gender, dosage, calendar year and clinical risk factors using Cox regression. Persistence was calculated by measuring repeat prescribing and compliance by estimating the medication possession ratio. A unique patient-based decision model was then developed using these probabilities. By varying the persistence and compliance probabilities in the simulation, the fracture outcomes with different scenarios were then evaluated. The outcomes were simulated over a 4-year period (maximum of three years of bisphosphonate use followed by 1 year of offset). It was assumed that the bisphosphonate users had experienced similar fracture reductions as observed in clinical trials. RESULTS The study population included 44 531 patients. Modelling showed that improvement of the 3-year persistence by 10% (over current persistence) would prevent an additional 14.4 hip fractures per 10 000 patients with weekly treatment. If weekly was substituted with yearly treatment (refill once a year), an additional 68.4 hip fractures (per 10 000 patients) would be prevented. If 3-year persistence improved by 10% with yearly treatment, an additional 78.5 hip fractures would be prevented compared to monthly bisphosphonates. The effects of this substitution were largest in elderly patients and in women. CONCLUSION Improvements in treatment persistence and compliance may improve the impact of bisphosphonates in reducing the risk of fractures. Yearly administration may also improve the impact on fracture risk reduction, unless long-term persistence is substantially reduced.

Abstract
Background The tumor suppressor p53 is an important regulator that controls various cellular networks, including cell differentiation. Interestingly, some studies suggest that p53 facilitates cell differentiation, whereas others claim that it suppresses differentiation. Therefore, it is critical to evaluate whether this inconsistency represents an authentic differential p53 activity manifested in the various differentiation programs. Methodology/Principal Findings To clarify this important issue, we conducted a comparative study of several mesenchymal differentiation programs. The effects of p53 knockdown or enhanced activity were analyzed in mouse and human mesenchymal cells, representing various stages of several differentiation programs. We found that p53 down-regulated the expression of master differentiation-inducing transcription factors, thereby inhibiting osteogenic, adipogenic and smooth muscle differentiation of multiple mesenchymal cell types. In contrast, p53 is essential for skeletal muscle differentiation and osteogenic re-programming of skeletal muscle committed cells. Conclusions These comparative studies suggest that, depending on the specific cell type and the specific differentiation program, p53 may exert a positive or a negative effect, and thus can be referred as a “guardian of differentiation” at large.

Abstract
OBJECTIVE To identify determinants of non-compliance with bisphosphonates in women with postmenopausal osteoporosis. By considering the year of the introduction of weekly bisphosphonates important additional information is obtained. METHODS New female users of daily or weekly alendronate or risedronate between 1999 and 2004, aged >or= 45 years were identified from PHARMO RLS, including drug-dispensing and hospitalisation data of > 2 million residents of the Netherlands. One-year compliance with bisphosphonates was measured using the Medication Possession Ratio (MPR). To identify determinants of non-compliance, non-compliant women (MPR < 50%) were compared to compliant women (MPR >or= 80%). The effect of patient age, prescriber, initial dosing regimen, gastrointestinal adverse events, co-medication and fractures on non-compliance was investigated. RESULTS The study cohort included 8822 new users of bisphosphonates, of whom 5079 (58%) were compliant and 2720 (31%) were non-compliant after 1 year. Only 1023 women (11%) had a MPR between >or= 50% and < 80%. Daily dosing at start, increased number of co-medications and new use of intestinal agents in the year after starting bisphosphonates were independently associated with an increased odds of non-compliance. In contrast, higher age, first prescription from a specialist, osteoporosis related hospitalisation and use of NSAIDs in the year preceding bisphosphonate therapy decreased the odds of non-compliance. CONCLUSION This study revealed several determinants of non-compliance with bisphosphonates, the best controllable being the type of initial bisphosphonate, with daily dosing leading to more non-compliance than weekly dosing. However, compliance for both regimens is suboptimal, pointing to an unmet medical need.

Abstract
UNLABELLED Among 8,822 new female bisphosphonate users, non-compliant bisphosphonate use was associated with a 45% increased risk of osteoporotic fracture compared to compliant use (MPR >or=80%). Classifying compliance into five categories, fracture risk gradually increased with poorer compliance. These results emphasize the importance of treatment compliance in obtaining maximal treatment benefit. INTRODUCTION Bisphosphonates are widely used to treat osteoporosis and reduce fracture risk. Low compliance is frequent and will limit treatment benefit. METHODS New female users of alendronate or risedronate between 1999-2004, aged >or=45 years were identified from PHARMO-RLS, including drug-dispensing and hospitalization data of >or= 2 million residents of the Netherlands. Patients were followed until first hospitalisation for an osteoporotic fracture, death, or end of study period. Compliance with bisphosphonates during follow-up was measured over 90-day intervals using Medication Possession Ratio (MPR). The association between compliance and fracture risk was analyzed using time-dependent Cox-regression. RESULTS The study cohort included 8,822 new female bisphosphonate users, contributing in total 22,484 person-years of follow-up. During follow-up, 176 osteoporotic fractures occurred (excluding the first six months). Non-compliant bisphosphonate use was associated with a 45% increased fracture risk compared to compliant use (MPR >or= 80%). Classifying compliance into five categories, fracture risk gradually increased with poorer compliance (p-value <0.05 for trend). A MPR <20% was associated with an 80% increased fracture risk compared to a MPR >or= 90%. CONCLUSIONS These results show a statistically significant association between level of compliance with bisphosphonates and level of fracture risk, emphasizing the importance of treatment compliance in obtaining maximal treatment benefit.

Abstract
Salmon calcitonin, available as a therapeutic agent for more than 30 years, demonstrates clinical utility in the treatment of such metabolic bone diseases as osteoporosis and Paget's disease, and potentially in the treatment of osteoarthritis. This review considers the physiology and pharmacology of salmon calcitonin, the evidence based research demonstrating efficacy and safety of this medication in postmenopausal osteoporosis with potentially an effect on bone quality to explain its abilities to reduce the risk of spine fracture, the development of an oral salmon calcitonin preparation, and the therapeutic rationale for this preparation's chondroprotective effect in osteoarthritis.

Abstract
High-precision measurements of the proton elastic form-factor ratio, mu pG p E/G p M, have been made at four-momentum transfer, Q2, values between 0.2 and 0.5 GeV2. The new data, while consistent with previous results, clearly show a ratio less than unity and significant differences from the central values of several recent phenomenological fits. By combining the new form-factor ratio data with an existing cross-section measurement, one finds that in this Q2 range the deviation from unity is primarily due to G p E being smaller than expected.

Abstract
This study was designed to determine whether power spectral analysis (PSA) of heart rate variability (HRV) can detect change in autonomic tone following a relaxation intervention called therapeutic touch (TT). Thirty healthy subjects underwent TT by one of three TT practitioners using the steps developed by Krieger and Kunz (The Therapeutic Touch, Prentice-Hall, 1979). Both subjects and TT practitioners were monitored by continuous electrocardiographic monitoring (Holter) before (15 minutes), during, and after (15 minutes) TT was administered. Subjects and TT practitioners completed a visual analogue scale (VAS) of perceived stress before and after TT. Change scores for VAS and PSA of high-frequency/low-frequency (HF/LF) ratios were compared for the 2-minute interval before TT began and the end of TT and the end of the recovery period, using t tests. VAS scores decreased (less stress) from before to after TT for both subjects (p < 0.0005) and TT practitioners (p < 0.0005). Mean HF/LF ratios increased significantly to reflect greater parasympathetic dominance from before TT to the end of treatment for subjects (p = 0.006), but not for TT practitioners. However, further analysis revealed that this change was due to an exaggerated HF/LF response from four outliers (p < 0.0005). Data collected in this study did not reveal differences between these four subjects and the rest of the sample. There were no significant changes in HF/LF ratios from the end of TT to end of recovery for either group. Further research is needed to determine why some subjects may have greater change in autonomic tone in response to relaxation in order to be able to predict who will demonstrate physiologic response to relaxation interventions.

Abstract
Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is a glycoprotein that is part of the carcinoembryonic antigen and the immunoglobulin superfamilies. We have shown that it functions as a tumor suppressor and that this function depends upon the presence of the longer CEACAM1 cytoplasmic domain. In this report, we describe the generation of a Ceacam1-/- mouse. The Ceacam1-/- colon exhibits increased in vivo proliferation relative to the wild-type counterpart with a corresponding decreased expression of the p21(Cip1) and p27(Kip1) Cyclin D kinase inhibitors. The colonic villi undergo decreased apoptosis. Out of 35 litters of mice, no spontaneous tumors in any tissues normally expressing CEACAM1 were found over the lifespan of the animals, suggesting that CEACAM1 may not be involved in initiation of tumor development. However, when mice are treated with azoxymethane to induce colonic tumors, we find that Ceacam1-/- mice developed a significantly greater number of tumors than their littermate controls. Moreover, the tumor size was greater in the knockout mice relative to that in the wild-type mice. These results indicate that deletion of CEACAM1 favors progression of colon tumorigenesis.

Abstract
We report on a precision measurement of the parity-violating asymmetry in fixed target electron-electron (Møller) scattering: A(PV) = [-131 +/- 14(stat) +/- 10(syst)] x 10(-9), leading to the determination of the weak mixing angle sin2(thetaW(eff) = 0.2397 +/- 0.0010(stat) +/- 0.0008(syst), evaluated at Q2 = 0.026 GeV2. Combining this result with the measurements of sin2(thetaW(eff) at the Z0 pole, the running of the weak mixing angle is observed with over 6sigma significance. The measurement sets constraints on new physics effects at the TeV scale.

Abstract
Narrow-leaved lupine (Lupinus angustifolius L.) is grown as a grain legume crop in Australia and Europe where it is used as feedstock in the livestock and aquaculture industries. During July 2003, a stem rot disease was observed in narrow-leaved lupine (cv. Arabella) plants in a research plot at the Crop Diversification Centre North (CDCN), Edmonton, Alberta, Canada. The disease was also found on cv. Rose at the CDCN and cv. Arabella in experimental fields near Devon, Ellerslie, and Westlock, Alberta during the late spring of 2004. Diseased plants showed dark brown-to-black stems with sunken and constricted lesions at the soil level. Young leaves became shrunken and twisted and seedlings collapsed. Rhizoctonia solani was consistently isolated from lesions on taproots and basal stems of diseased plants. Colonies of cream-colored mycelia grew close to the surface of potato dextrose agar (PDA). Most sclerotia formed inside the medium. Agar disks (1 cm in diameter) of isolates LP-11Bb, LP-24C, and LP-25C were attached to the opposite sides of basal stems (180° apart) of 1-month-old lupine seedlings (cv. Arabella). Inoculated plants were incubated for 2 days in black plastic bags under a greenhouse bench at approximately 20°C. All isolates caused brown lesions on the lower stems (extending up to 7 cm above ground level), girdling, and root rot. Plants wilted within 7 to 10 days after inoculation, and aerial mycelia appeared on the basal stems. R. solani was reisolated from the infected crown tissues using PDA to complete Koch's postulates. The isolates were paired with AG tester strains of R. solani. Isolates LP-11Bb and LP-24C were identified as AG-4 while isolate LP-25C was identified as AG-2-2. In another trial, eight isolates of R. solani (unknown AG types) were tested for virulence on L. angustifolius cv. Arabella using the inoculation method described above. All isolates were pathogenic, and disease severity that was based on a 0 to 4 scale ranged from 2.7 to 3.2. The most virulent strain was LP-24C, which caused a 77% loss in fresh weight compared with the noninoculated control plants. R. solani AG-8 is associated with Rhizoctonia disease of lupine in Australia (1) and also causes bare patch disease of wheat. To our knowledge, this is the first report of R. solani on lupine in Canada. This disease could have a significant impact on the commercial production of lupine in Alberta. Reference: (1) M. W.

Abstract
We report a measurement of the parity-violating asymmetry in fixed target electron-electron (Møller) scattering: A(PV)=[-175+/-30(stat)+/-20(syst)] x 10(-9). This first direct observation of parity nonconservation in Møller scattering leads to a measurement of the electron's weak charge at low energy Q(e)(W)=-0.053+/-0.011. This is consistent with the standard model expectation at the current level of precision: sin((2)theta(W)(M(Z))((-)MS)=0.2293+/-0.0024(stat)+/-0.0016(syst)+/-0.0006(theory).

Abstract
The structure and infectivity of the oocysts of a new species of Cryptosporidium from the feces of humans are described. Oocysts are structurally indistinguishable from those of Cryptosporidium parvum. Oocysts of the new species are passed fully sporulated, lack sporocysts. and measure 4.4-5.4 microm (mean = 4.86) x 4.4-5.9 microm (mean = 5.2 microm) with a length to width ratio 1.0-1.09 (mean 1.07) (n = 100). Oocysts were not infectious for ARC Swiss mice, nude mice. Wistar rat pups, puppies, kittens or calves, but were infectious to neonatal gnotobiotic pigs. Pathogenicity studies in the gnotobiotic pig model revealed significant differences in parasite-associated lesion distribution (P = 0.005 to P = 0.02) and intensity of infection (P = 0.04) between C. parvum and this newly described species from humans. In vitro cultivation studies have also revealed growth differences between the two species. Multi-locus analysis of numerous unlinked loci, including a preliminary sequence scan of the entire genome demonstrated this species to be distinct from C. parvum and also demonstrated a lack of recombination, providing further support for its species status. Based on biological and molecular data, this Cryptosporidium infecting the intestine of humans is proposed to be a new species Cryptosporidium hominis n. sp.
