Abstract
Thermochemical data for the homolytic P–P bond fission in tetraaminodiphosphanes (R2N)2P–P(NR2)2 were determined experimentally and computationally. The results confirm that radical formation is favoured by entropic and structural relaxation effects, and disfavoured by dispersion forces. Unlike aminophosphenium cations, the radicals display no strong preference for a planar (R2N)2P unit.

Abstract
OBJECTIVE The Neonatal Resuscitation Program (NRP) has transitioned to a simulation-based format. We hypothesized that immersive simulation differentially impacts similar trainee populations' resuscitation knowledge, procedural skill and teamwork behavior. STUDY DESIGN Residents from NICU and non-NICU programs were randomized to either control or a booster simulation 7 to 10 months after NRP. Procedural skill and teamwork behavior instruments were validated. Individual resident's resuscitation performance was assessed at 15 to 18 months. Three reviewers rated videos. RESULT Fifty residents were assessed. Inter-rater reliability was good for procedural skills (0.78) and team behavior (0.74) instruments. The intervention group demonstrated better procedural skills (71.6 versus 64.4) and teamwork behaviors (18.8 versus 16.2). The NICU program demonstrated better teamwork behaviors (18.6 versus 15.5) compared with non-NICU program. CONCLUSION A simulation-enhanced booster session 9 months after NRP differentiates procedural skill and teamwork behavior at 15 months. Deliberate practice with simulation enhances teamwork behaviors additively with residents' clinical resuscitation exposure.

Abstract
Thailand has had multiple poultry outbreaks of highly pathogenic avian influenza (HPAI) H5N1 since its first emergence in 2004. Twenty-five human cases of HPAI H5N1 avian influenza have been reported in the country, including 17 fatalities, and contact with infected dead or dying poultry has been identified as a risk factor for human infection. This study assessed the use of protective equipment and hand hygiene measures by Thai poultry-owning households during activities involving poultry contact. Surveys conducted in 2008 included questions regarding poultry-related activities and protective measures used during an HPAI outbreak (2005) and 3 years after the study location's last reported outbreak (2008). For both time periods, poultry owners reported limited use of personal protective equipment (PPE) during all activities and inconsistent hand washing practices after carrying poultry and gathering eggs. This is the first time that PPE use in Thailand has been quantified for a large study group. These data are important for ongoing characterization of HPAI risk and for the crafting of educational messages.

Abstract
Influenza A virus infections commonly cause respiratory disease in swine and can be transmitted between people and pigs, with potentially novel strains introduced into herds and spilling back into the human population. The goals of this study were to characterize influenza infections in Minnesota pigs and assess biosecurity measures used by swine workers. Veterinarians submitting influenza-positive swine samples to the University of Minnesota Veterinary Diagnostic Laboratory between October 2007 and April 2009 were surveyed regarding disease-related information and biosecurity procedures at each farm. Influenza-positive samples were submitted year-round, peaking in spring and fall. H1N1 was the most commonly detected subtype (56%), followed by H3N2 (14%) and H1N2 (12%). Most positive submissions were associated with illness in growing pigs (median age 8.8 weeks, IQR 5-15). Median morbidity and mortality were 25% (IQR 10-48) and 2% (IQR 0.5-3.5), respectively. Vaccination of sows and growing pigs was conducted at 71% and 7.9% of the swine farms, respectively. Specialized footwear was reported as the most common form of protective equipment used by workers. Employee vaccination for seasonal influenza was 19%. The sow vaccination rate in this study is consistent with national data, although growing pig vaccination is lower than the national average. Seasonal and age trends identified here may provide diagnostic guidance when growing pigs experience respiratory disease. Inconsistent use of protective equipment and employee vaccination at swine farms indicates the need for further discussion and research of approaches to minimize interspecies influenza transmission on swine farms.

Abstract
BACKGROUND The objective of this study was to examine the effects of low-dose pregabalin on the analgesic efficacy, side-effects, and recovery profile in patients undergoing laparoscopic cholecystectomy. METHODS One hundred and sixty-two patients aged 18-65 yr, of ASA physical status I-III, undergoing elective outpatient laparoscopic cholecystectomy were recruited and randomized in this prospective, placebo-controlled, double-blind study to receive one of the following study medications orally: pregabalin 50 mg, pregabalin 75 mg, or placebo, 1 h before surgery and then every 12 h after operation for a total of three doses. Postoperative numeric pain scores, analgesic consumption, recovery score (QoR-40), and side-effects (opioid-related symptom distress scale) were assessed in the early postoperative period (every 15 min during the first hour, at 90, 120 min, 6, and 12 h) and at days 1, 2, and 7. Data were analysed using an intention-to-treat method. RESULTS Compared with the placebo group, the pain scores were lower in the pregabalin 75 mg group in the first 90 min after surgery (P<0.05). Pregabalin 50 mg resulted in pain reduction at 30 and 45 min (P<0.05) relative to placebo. The analgesic consumption, side-effects, and recovery scores were similar among the three groups. CONCLUSIONS Perioperative administration of pregabalin 75 mg provided limited analgesic benefit in the postoperative period. An updated meta-analysis confirms this finding (see Supplementary material).

Abstract
Six strains of Clostridium thermocellum isolated from various environments were characterized as to growth rate, production of reducing sugars, ethanol, and acetic acid from cellulose, base composition of DNA, and the abilities to adapt to ethanol and to grow at 45 degrees C. Five of the six new isolates produced 7 to 15% more ethanol and two produced about 45% more reducing sugars than a standard reference strain. One strain (MC-6) adapted more readily to growth in 2% ethanol than the others.

Abstract
We report on the development of a microelectromechanical systems (MEMS)-scale photoacoustic sensor for the detection of trace gases. A mid-infrared quantum cascade laser (QCL) was used to determine detection limits for acetic acid, acetone, 1,4-dioxane, and vinyl acetate. The source was continuously tunable from 1015 cm−1 to 1240 cm−1, allowing for the collection of photoacoustic vibrational spectra for these gases. Exceptional agreement between the measured photoacoustic spectra and the infrared spectra for acetic acid, acetone, 1,4-dioxane, and vinyl acetate was observed. Partial least-squares (PLS) regression was used to develop an algorithm for classification of these compounds based solely on photoacoustic spectra.

Abstract
We present a camera-based method for automatically quantifying the individual and social behaviors of fruit flies, Drosophila melanogaster, interacting in a planar arena. Our system includes machine-vision algorithms that accurately track many individuals without swapping identities and classification algorithms that detect behaviors. The data may be represented as an ethogram that plots the time course of behaviors exhibited by each fly or as a vector that concisely captures the statistical properties of all behaviors displayed in a given period. We found that behavioral differences between individuals were consistent over time and were sufficient to accurately predict gender and genotype. In addition, we found that the relative positions of flies during social interactions vary according to gender, genotype and social environment. We expect that our software, which permits high-throughput screening, will complement existing molecular methods available in Drosophila, facilitating new investigations into the genetic and cellular basis of behavior.

Abstract
8080 Background: Single agent rituximab produces a high response rate when used as first-line treatment, and maintenance rituximab prolongs remission duration. Active immunotherapy is a promising treatment approach, when administered following remission induction by initial therapy. In this phase II trial, we evaluate the feasibility, toxicity, and efficacy of administering concurrent maintenance rituximab plus Id-KLH vaccine in pts with low-grade NHL. Methods: Pts with previously untreated low-grade NHL (grade 1/2 follicular or SLL) who were judged to be candidates for single agent rituximab therapy were eligible. All pts had initial biopsy for production of the Id-KLH vaccine. All pts received rituximab 375mg/m2 IV, weekly × 4. Pts with CR/CRu, PR, or stable disease at 8 weeks proceeded with maintenance rituximab (standard 4 week courses at 6 month intervals for 3 courses) and Id-KLH vaccination (Id-KLH 1cc day 1; GMCSF 250μg SQ days 1–4) monthly × 8, beginning month 3, then every 2 months during the second year. Pts were monitored for response rate, progression- free survival, and toxicity. Results: To date, 36 of a planned 56 pts have been enrolled. Idiotype vaccine was successfully manufactured in 27 of 32 pts (84%), with 4 in production. Of the 27 pts for whom Id-KLH was successfully manufactured, 2 progressed during rituximab. 19 of 25 pts (14FL;5SLL) have had response determined after rituximab: 8 PR (42%), 11 stable (58%; 4 of 5 SLL). Pts have now received rituximab maintenance therapy plus Id-KLH for durations of 6 - 34 months. 6 of 19 pts (3 SLL) progressed at months 5, 6, 9, 9, 10, and 12, respectively. Treatment has been well tolerated, with no unusual toxicities observed. Rituximab-related hypotension and atrial fibrillation occurred in 1 pt. The most common Id-KLH related adverse event has been injection site reaction. Conclusions: Concurrent maintenance therapy with rituximab plus Id-KLH is safe and well tolerated. At present, 6 of 25 pts (24%) have progressed (including 3 of the 5 SLL pts) with a median followup of 19 months. This trial is continuing. No significant financial relationships to disclose.

Abstract
3068 Background: The 10-peptide EP-2101 vaccine is designed to induce multi-specific CTL responses against epitopes in CEA, p53, HER-2/neu and MAGE 2/3. Seven epitopes are modified for enhanced MHC binding or heteroclitic T-cell activation including the previously described CAP1–6D heteroclitic analog and 2 epitopes are native wild-type (WT) sequences. Also included is the helper epitope PADRE. We report here immunogenicity results from a Phase II trial of the EP-2101 vaccine. Methods: 66 HLA-A2+ good performance patients with Stage IIIB/IV NSCLC were enrolled. Patients received 6 induction doses (0.5 mg/epitope) q3 wks followed by maintenance treatments at 2–3 month intervals. Endpoints included survival and induction of immune responses. CTL responses in peripheral blood MNC were measured after a 10 day in vitro stimulation with peptide followed by an IFNγ ELISPOT assay. Results: 33 patients completed induction and the first 11 patients were monitored for CTL against all vaccine epitopes. Seven of 11 patients generated responses against ≥ 4 epitopes after 3 and 6 vaccine doses and 8 patients generated CTL against ≥ 3 WT vaccine epitopes and WT sequences of vaccine analogs. Responses ranged between 10–50 spots/5x10e4 cells with stronger responses of >100 spots observed. All 9 vaccine epitopes were immunogenic in at least 1 patient. CTL responses against epitopes were maintained at Wk 30 and/or Month 9 in 7 of 8 patients. At Month 12, 2 of 4 patients also had detectable CTL against the vaccine. The 22 remaining patients were monitored against 5 representative vaccine epitopes. 13 of these patients generated CTL responses to ≥ 2 epitopes and 7 patients generated responses to ≥ 3 epitopes. Th-cell responses against PADRE measured with a direct IFNγ ELISPOT assay were observed in 18 of the 33 patients tested. Toxicities attributable to vaccine were mild and consisted mostly of injection site reactions. Follow-up for survival is ongoing. Conclusions: The peptide vaccine EP-2101 is well-tolerated and induces broadly-specific CTL responses in metastatic NSCLC patients. [Table: see text]
