Abstract
A Particle X-ray Temporal Diagnostic (PXTD) has been implemented on OMEGA for simultaneous time-resolved measurements of several nuclear products as well as the x-ray continuum produced in High Energy Density Plasmas and Inertial Confinement Fusion implosions. The PXTD removes systematic timing uncertainties typically introduced by using multiple instruments, and it has been used to measure DD, DT, D3He, and T3He reaction histories and the emission history of the x-ray core continuum with relative timing uncertainties within ±10-20 ps. This enables, for the first time, accurate and simultaneous measurements of the x-ray emission histories, nuclear reaction histories, their time differences, and measurements of Ti(t) and Te(t) from which an assessment of multiple-ion-fluid effects, kinetic effects during the shock-burn phase, and ion-electron equilibration rates can be made.

Abstract
Supported by a kinetic simulation, we derive an exclusion energy parameter E_{X} providing a lower kinetic energy bound for an electron to cross from one inflow region to the other during magnetic reconnection. As by a Maxwell demon, only high-energy electrons are permitted to cross the inner reconnection region, setting the electron distribution function observed along the low-density side separatrix during asymmetric reconnection. The analytic model accounts for the two distinct flavors of crescent-shaped electron distributions observed by spacecraft in a thin boundary layer along the low-density separatrix.

Abstract
BACKGROUND Anti-viral therapy in chronic hepatitis B (CHB) is associated with a reduced risk of hepatocellular carcinoma (HCC) primary described in patients with cirrhosis. AIM To examine the effects of treatment on HCC incidence in CHB with and without cirrhosis, after adjustment for background risks. METHODS A total of 2255 CHB patients from a US cohort (973 received anti-viral therapy) and 3653 patients from the community-based Taiwanese REVEAL-HBV study, none of whom received treatment. We used Cox proportional hazard models to calculate the risk of developing HCC after adjustment with the previously validated REACH-B risk score. RESULTS We found 273 incident cases of HCC. After adjustment, therapy lowered the risk of HCC development in the US treated cohort when compared to the US untreated cohort (HR 0.31; 95% CI: 0.15-0.66; P = 0.002). HCC risk reduction was also confirmed when compared to the REVEAL cohort (HR 0.22; 95% CI: 0.12-0.40; P < 0.001). Each REACH-B point was associated with a 53% increased risk of HCC (HR 1.53; 95% CI 1.46-1.59; P < 0.001). We found a significant statistical reduction in HCC incidence with therapy regardless of gender, age, cirrhosis status, HBeAg serology, alanine aminotransferase level, REACH-B score or treatment medication. Therapy was beneficial to those with mildly- to moderately elevated HBV DNA levels (>2000 IU/mL) and of even greater benefit to those with levels >200 000 IU/mL. CONCLUSION After adjustment for background risk, anti-viral therapy was associated with a significant reduction in HCC incidence in both community and real-life clinical cohorts, including in those patients previously thought to be at low risk.

Abstract
Exposure to particulate matter (PM), a major component of air pollution, contributes to increased morbidity and mortality worldwide. PM induces innate immune responses and contributes to allergic sensitization, although the mechanisms governing this process remain unclear. Lung mucosal uric acid has also been linked to allergic sensitization. The links among PM exposure, uric acid, and allergic sensitization remain unexplored. We therefore investigated the mechanisms behind PM-induced allergic sensitization in the context of lung mucosal uric acid. PM10 and house dust mite exposure selectively induced lung mucosal uric acid production and secretion in vivo, which did not occur with other challenges (lipopolysaccharide, virus, bacteria, or inflammatory/fibrotic stimuli). PM10-induced uric acid mediates allergic sensitization and augments antigen-specific T-cell proliferation, which is inhibited by uricase. We then demonstrate that human airway epithelial cells secrete uric acid basally and after stimulation through a previously unidentified mucosal secretion system. Our work discovers a previously unknown mechanism of air pollution-induced, uric acid-mediated, allergic sensitization that may be important in the pathogenesis of asthma.

Abstract
OBJECTIVE To explore the causes of rectal injuries during laparoscopic peritoneal vaginoplasty (Luohu operation) and assess measures that can be taken to increase safety of the operation. MATERIALS AND METHODS Data of patients with rectal injuries that occurred during Luohu vaginoplasty were analyzed retrospectively. RESULTS Three hundred and six patients received Luohu vaginoplasty. Rectal injuries occurred in 13 patients (4.2%). All patients recovered after intraoperative repair or postoperative rectovaginal fistula repair, performed within three to six months. Full display of the anatomical structures at the bottom of the pelvic cavity and successful construction of the vaginal tunnel are the two most important requirements for reducing the risk of rectal injury in laparoscopic vaginoplasty. In repair of fistulae postoperatively, it is important that resection of tissues or scars around the fistulae be avoided in order to reduce the chance of a injuries caused by diverting colostomy or colostomy closure. CONCLUSION Laparoscopic vaginoplasty is a generally safe procedure, but rectal injury can occur. Retaining the tissues or scars around the rectovaginal fistula can be successfully repaired, either when they are recognized during the operation or within a few months postoperatively.

Abstract
As duplicate publication is unethical, our aim was to find out how common it is among published papers on oral and maxillofacial surgery. We used PubMed to identify index articles published in 2010 in the Journal of Oral and Maxillofacial Surgery, the British Journal of Oral and Maxillofacial Surgery, and the European Journal of Cranio-Maxillo-Facial Surgery, and searched for possible duplicate publications from 2008 to 2012 using the first or second and last authors' names. Suspected duplicates were categorised into "non-duplicate" (no overlap), "duplicate" (identical results and conclusions), or "salami-sliced" publications (part of the index article repeated or continued). Of the 589 index articles, 17 (3%) had some form of duplication, but specifically, we found 3 duplicate, and 15 salami-sliced publications. Most redundant articles originated from China (n=4), followed by Italy, Japan, and Germany (3 from each) and the United States and Denmark (2 each). Of the 18 redundant publications, 9 did not reference the related index article. Duplicate material is still being published, and salami-slicing is relatively common among publications on oral and maxillofacial surgery. Further research is required into the extent and impact of this finding.

Abstract
BACKGROUND/AIMS To explore the value of hysteroscope and laparoscope in removing an incarcerated or ectopic intrauterine device (IUD). MATERIALS AND METHODS A 33-year-old woman was admitted to the present hospital on May 22nd, 2013. An incarcerated IUD was proven by ultrasonography. An IUD had been implanted in October 2011. Clinical case report of an incarcerated IUD in the sigmoid colon. RESULTS An IUD was successfully removed with the assistance of hysteroscope and laparoscope. CONCLUSION Ultrasonography should be performed in the follow-up of the patients after IUD implantation. Ectopic or incarcerated IUD can be successfully removed with the assistance of hysteroscope and laparoscope with minimal trauma.

Abstract
The authors performed transvaginal repair of rectovaginal fistual (RVF) with bulbocavernosus fat pad by incising left side of the labia majora and retained scar tissues which were formed after three months for one patient. Repair of the RVF was successful and the patient had normal diet and defecation at a week after surgery. Previous gynecological surgery performed on the patient resulted in RVF accompanied by weak rectal tissues. Retaining the tissues and scars surrounding to the fistula and filling the fistula with bulbocavernosus fat pad tissue increased rectal wall thickness and facilitated healing. The efficacy of this surgical technique will need further studies with larger patient cohorts to establish a clear success rate.
