Abstract
Obesity has a multifactorial etiology and is known to be a state of chronic low-grade inflammation, known as meta-inflammation. This state is associated with the development of metabolic disorders such as glucose intolerance and nonalcoholic fatty liver disease. Pyruvate is a glycolytic metabolite and a crucial node in various metabolic pathways. However, its role and molecular mechanism in obesity and associated complications are obscure. In this study, we reported that pyruvate substantially inhibited adipogenic differentiation in vitro and its administration significantly prevented HFD-induced weight gain, white adipose tissue inflammation, and metabolic dysregulation. To identify the target proteins of pyruvate, drug affinity responsive target stability was employed with proteomics, cellular thermal shift assay, and isothermal drug response to detect the interactions between pyruvate and its molecular targets. Consequently, we identified cytosolic phospholipase A2 (cPLA2) as a novel molecular target of pyruvate and demonstrated that pyruvate restrained diet-induced obesity, white adipose tissue inflammation, and hepatic steatosis in a cPLA2-dependent manner. Studies with global ablation of cPLA2 in mice showed that the protective effects of pyruvate were largely abrogated, confirming the importance of pyruvate/cPLA2 interaction in pyruvate attenuation of inflammation and obesity. Overall, our study not only establishes pyruvate as an antagonist of cPLA2 signaling and a potential therapeutic option for obesity, but it also sheds light on the mechanism of its action. Pyruvate's prior clinical use indicates that it can be considered a safe and viable alternative for obesity, whether consumed as a dietary supplement or as part of a regular diet.

Abstract
Osteoarthritis (OA) is the most common joint disease. Currently there are no effective methods that simultaneously prevent joint degeneration and reduce pain1. Although limited evidence suggests the existence of voltage-gated sodium channels (VGSCs) in chondrocytes2, their expression and function in chondrocytes and in OA remain essentially unknown. Here we identify Nav1.7 as an OA-associated VGSC and demonstrate that human OA chondrocytes express functional Nav1.7 channels, with a density of 0.1 to 0.15 channels per µm2 and 350 to 525 channels per cell. Serial genetic ablation of Nav1.7 in multiple mouse models demonstrates that Nav1.7 expressed in dorsal root ganglia neurons is involved in pain, whereas Nav1.7 in chondrocytes regulates OA progression. Pharmacological blockade of Nav1.7 with selective or clinically used pan-Nav channel blockers significantly ameliorates the progression of structural joint damage, and reduces OA pain behaviour. Mechanistically, Nav1.7 blockers regulate intracellular Ca2+ signalling and the chondrocyte secretome, which in turn affects chondrocyte biology and OA progression. Identification of Nav1.7 as a novel chondrocyte-expressed, OA-associated channel uncovers a dual target for the development of disease-modifying and non-opioid pain relief treatment for OA.

Abstract
Hydrogels with long-term storage stability, controllable sustained-release properties, and biocompatibility have been garnering attention as carriers for drug/growth factor delivery in tissue engineering applications. Chitosan (CS)/Graphene Oxide (GO)/Hydroxyethyl cellulose (HEC)/β-glycerol phosphate (β-GP) hydrogel is capable of forming a 3D gel network at physiological temperature (37 °C), rendering it an excellent candidate for use as an injectable biomaterial. This work focused on an injectable thermo-responsive CS/GO/HEC/β-GP hydrogel, which was designed to deliver Atsttrin, an engineered derivative of a known chondrogenic and anti-inflammatory growth factor-like molecule progranulin. The combination of the CS/GO/HEC/β-GP hydrogel and Atsttrin provides a unique biochemical and biomechanical environment to enhance fracture healing. CS/GO/HEC/β-GP hydrogels with increased amounts of GO exhibited rapid sol-gel transition, higher viscosity, and sustained release of Atsttrin. In addition, these hydrogels exhibited a porous interconnected structure. The combination of Atsttrin and hydrogel successfully promoted chondrogenesis and osteogenesis of bone marrow mesenchymal stem cells (bmMSCs) in vitro. Furthermore, the work also presented in vivo evidence that injection of Atsttrin-loaded CS/GO/HEC/β-GP hydrogel stimulated diabetic fracture healing by simultaneously inhibiting inflammatory and stimulating cartilage regeneration and endochondral bone formation signaling pathways. Collectively, the developed injectable thermo-responsive CS/GO/HEC/βG-P hydrogel yielded to be minimally invasive, as well as capable of prolonged and sustained delivery of Atsttrin, for therapeutic application in impaired fracture healing, particularly diabetic fracture healing.

Abstract
AIMS To compare the cost-effectiveness of stereotactic ablative body radiation therapy (SABR) with radiofrequency ablation and surgery in adult patients with metastatic liver cancer and hepatocellular carcinoma (HCC). MATERIALS AND METHODS Two patient cohorts were assessed: liver oligometastases and HCC. For each patient cohort, a decision analytic model was constructed to assess the cost-effectiveness of interventions over a 5-year horizon. A Markov process was embedded in the decision model to simulate the possible prognosis of cancer. Data on transition probabilities, survival, side-effects, quality of life and costs were obtained from published sources and the SABR Commissioning through Evaluation (CtE) scheme. The primary outcome was the incremental cost-effectiveness ratio with respect to quality-adjusted life-years. The robustness of the results was examined in a sensitivity analysis. Analyses were conducted from a National Health Service and Personal Social Services perspective. RESULTS In the base case analysis, which assumed that all three interventions were associated with the same cancer progression rates and mortality rates, SABR was the most cost-effective intervention for both patient cohorts. This conclusion was sensitive to the cancer progression rate, mortality rate and cost of interventions. Assuming a willingness-to-pay threshold of £20 000 per quality-adjusted life-year, the probability that SABR is cost-effective was 57% and 50% in liver oligometastases and HCC, respectively. CONCLUSIONS Our results indicate a potential for SABR to be cost-effective for patients with liver oligometastases and HCC. This finding supports further investigation in clinical trials directly comparing SABR with surgery and radiofrequency ablation.

Abstract
AIMS Lenvatinib is an oral multi-kinase inhibitor approved for the treatment of adults with progressive, locally advanced or metastatic, differentiated thyroid carcinoma refractory to radioactive iodine. MATERIALS AND METHODS A literature review was undertaken to inform the development of consensus-based guidance for the routine management of adverse events associated with lenvatinib. PubMed was searched on 24 October 2017; the search terms were 'lenvatinib' and 'thyroid cancer'. RESULTS Hypertension, diarrhoea, weight loss, skin toxicities and cardiovascular adverse events were considered. For grade 1/2 diarrhoea, initial treatment should be loperamide with a 1-week treatment interruption if diarrhoea persists and dose reduction if diarrhoea recurs on reinitiation of lenvatinib. Blood pressure should be monitored daily in patients with pre-existing hypertension, otherwise from 1 week after the initiation of lenvatinib and weekly for the first 2 months. For patients with systolic blood pressure ≥135 mmHg to <160 mmHg or diastolic blood pressure ≥85 mmHg to <100 mmHg, lenvatinib should be continued but antihypertensive therapy initiated/intensified. For patients who remain hypertensive, a treatment break can be considered with lenvatinib reinitiated at a reduced dose once the patient's blood pressure has stabilised for at least 48 h. Weight loss of 10% of baseline body weight or the onset of anorexia should be managed with a 1-week treatment break; patients should maintain a healthy, active lifestyle. For patients with grade 2 proteinuria, lenvatinib may be continued, but an angiotensin II receptor blocker or angiotensin converting enzyme inhibitor should be commenced. For grade >3 proteinuria, lenvatinib should be interrupted until proteinuria returns to 1+. For chronic proteinuria, lenvatinib should be stopped. Skin toxicities should be managed with moisturisers or emollients and soap substitutes. CONCLUSIONS Prophylaxis, regular monitoring and symptomatic management with appropriate short treatment breaks and, for persistent adverse events, dose reductions, are recommended to enable patients to remain on the optimal dose regimen.

Abstract
Temporally modulated electron beams have a wide array of applications ranging from the generation of coherently enhanced electromagnetic radiation to the resonant excitation of electromagnetic wakefields in advanced-accelerator concepts. Likewise producing low-energy ultrashort microbunches could be useful for ultrafast electron diffraction and new accelerator-based light-source concepts. In this Letter we propose and experimentally demonstrate a passive microbunching technique capable of forming a picosecond bunch train at ∼6 MeV. The method relies on the excitation of electromagnetic wakefields as the beam propagates through a dielectric-lined waveguide. Owing to the nonultrarelativistic nature of the beam, the induced energy modulation eventually converts into a density modulation as the beam travels in a following free-space drift. The modulated beam is further accelerated to ∼20 MeV while preserving the imparted density modulation.

Abstract
Self-modulation of an electron beam in a plasma has been observed. The propagation of a long (several plasma wavelengths) electron bunch in an overdense plasma resulted in the production of multiple bunches via the self-modulation instability. Using a combination of a radio-frequency deflector and a dipole spectrometer, the time and energy structure of the self-modulated beam was measured. The longitudinal phase space measurement showed the modulation of a long electron bunch into three bunches with an approximately 200 keV/c amplitude momentum modulation. Demonstrating this effect is a breakthrough for proton-driven plasma accelerator schemes aiming to utilize the same physical effect.

Abstract
BACKGROUND AND PURPOSE Oral mucositis is an expected complication of radiotherapy in the management of carcinoma of the head and neck. The Common Terminology Criteria for Adverse Events (CTCAE) Version 3 (V3) and related systems based on mucosal appearance have been used in clinical trials historically. More recently, Version 4 (V4) which is based on patient symptoms has been employed. This study compares the use of V3 and V4 in the grading of mucositis in patients undergoing radiotherapy with or without concurrent systemic therapy for carcinoma of the oral cavity and oropharynx. METHODS Oral mucositis was graded prospectively in patients receiving radiotherapy with or without concurrent systemic therapy using both V3 and V4. Grading was recorded during and after completion of therapy. RESULTS Between November 2014 and November 2015, 555 measurements were taken from 73 patients. Mucositis scores were equal in both versions in 327 (59%) measurements. Significant differences between V3 and V4 were seen in patients receiving cetuximab-based concurrent therapy (p < 0.001) and beyond 8 weeks from the start of radiotherapy (p = 0.004). CONCLUSION Differences in grading of mucositis scored by V3 and V4 are frequent. Relationships between biologically effective dose and rates of grade 3 mucositis have historically been based on mucosal appearances. It is not known whether the same relationships apply when mucositis is graded based on symptomatic grading systems. Both V3 and V4 should be used in clinical trials to improve understanding of mucositis and its relationship to quality of life and late mucosal toxicity.

Abstract
Intravitreally administered lampalizumab is an investigational complement inhibitor directed against complement factor D (CFD) for the treatment of geographic atrophy (GA) secondary to age-related macular degeneration. We sought to develop an integrated ocular and systemic pharmacokinetic/pharmacodynamic model for lampalizumab in patients with GA using the data from the clinical phase I and II studies. The kinetics of lampalizumab and CFD disposition were well described by the combined ocular/serum target-mediated drug disposition model using a quasi-steady-state approximation. This model takes into account the drug, target, and drug-target complex clearance, their transfer rates between ocular and serum compartments, and turnover kinetics of CFD. The constructed model provided a prediction of target occupancy in ocular tissues and supported that the two dosing regimens (10 mg q4w and 10 mg q6w) selected for the phase III studies are expected to be efficacious and able to achieve near-complete target engagement in the vitreous humor.

Abstract
BACKGROUND SB939 is a potent oral inhibitor of class 1, 2, and 4 histone deacetylases (HDACs). These three HDAC classes are highly expressed in castration resistant prostate cancer (CRPC) and associated with poor clinical outcomes. We designed a phase II study of SB939 in men with metastatic CRPC. METHODS Patients received SB939 60 mg on alternate days three times per week for 3 weeks on a 4-week cycle. Primary endpoints were PSA response rate (RR) and progression-free survival (PFS). Secondary endpoints included objective response rate and duration; overall survival; circulating tumor cell (CTC) enumeration and safety. Exploratory correlative studies of the TMPRSS2-ERG fusion and PTEN biomarkers were also performed. RESULTS Thirty-two patients were enrolled of whom 88 % had received no prior chemotherapy. The median number of SB939 cycles administered was three (range 1-8). Adverse events were generally grade 1-2, with five pts experiencing one or more grade three event. One patient died due to myocardial infarction. A confirmed PSA response was noted in two pts (6 %), lasting 3.0 and 21.6 months. In patients with measurable disease there were no objective responses. Six patients had stable disease lasting 1.7 to 8.0 months. CTC response (from ≥5 at baseline to <5 at 6 or 12 weeks) occurred in 9/14 evaluable patients (64 %). CONCLUSION Although SB939 was tolerable at the dose/schedule given, and showed declines in CTC in the majority of evaluable patients, it did not show sufficient activity based on PSA RR to warrant further study as a single agent in unselected patients with CRPC.

Abstract
Primary emissions from a log wood burner and a pellet boiler were characterized by online measurements of the organic aerosol (OA) using a high-resolution time-of-flight aerosol mass spectrometer (HR-TOF-AMS) and of black carbon (BC). The OA and BC concentrations measured during the burning cycle of the log wood burner, batch wise fueled with wood logs, were highly variable and generally dominated by BC. The emissions of the pellet burner had, besides inorganic material, a high fraction of OA and a minor contribution of BC. However, during artificially induced poor burning BC was the dominating species with ∼80% of the measured mass. The elemental O:C ratio of the OA was generally found in the range of 0.2-0.5 during the startup phase or after reloading of the log wood burner. During the burnout or smoldering phase, O:C ratios increased up to 1.6-1.7, which is similar to the ratios found for the pellet boiler during stable burning conditions and higher than the O:C ratios observed for highly aged ambient OA. The organic emissions of both burners have a very similar H:C ratio at a given O:C ratio and therefore fall on the same line in the Van Krevelen diagram.

Abstract
This study reports the potential toxicological impact of particles produced during biomass combustion by an automatic pellet boiler and a traditional logwood stove under various combustion conditions using a novel profluorescent nitroxide probe, BPEAnit. This probe is weakly fluorescent but yields strong fluorescence emission upon radical trapping or redox activity. Samples were collected by bubbling aerosol through an impinger containing BPEAnit solution, followed by fluorescence measurement. The fluorescence of BPEAnit was measured for particles produced during various combustion phases: at the beginning of burning (cold start), stable combustion after refilling with the fuel (warm start), and poor burning conditions. For particles produced by the logwood stove under cold-start conditions, significantly higher amounts of reactive species per unit of particulate mass were observed compared to emissions produced during a warm start. In addition, sampling of logwood burning emissions after passing through a thermodenuder at 250 degrees C resulted in an 80-100% reduction of the fluorescence signal of the BPEAnit probe, indicating that the majority of reactive species were semivolatile. Moreover, the amount of reactive species showed a strong correlation with the amount of particulate organic material. This indicates the importance of semivolatile organics in particle-related toxicity. Particle emissions from the pellet boiler, although of similar mass concentration, were not observed to lead to an increase in fluorescence signal during any of the combustion phases.

Abstract
At eight European field sites, the impact of loss of plant diversity on primary productivity was simulated by synthesizing grassland communities with different numbers of plant species. Results differed in detail at each location, but there was an overall log-linear reduction of average aboveground biomass with loss of species. For a given number of species, communities with fewer functional groups were less productive. These diversity effects occurred along with differences associated with species composition and geographic location. Niche complementarity and positive species interactions appear to play a role in generating diversity-productivity relationships within sites in addition to sampling from the species pool.

Abstract
A retrospective study was conducted to evaluate treatment of foot and ankle ganglion cysts seen at the Foot and Ankle Institute at the Pennsylvania College of Podiatric Medicine (now Temple University School of Podiatric Medicine). From 1990 to 1997, 63 patients (63 ganglion cysts) were treated by conservative or surgical means. Statistical analysis of data collected showed a significant relationship between type of treatment received and recurrence of the cyst. Surgical intervention resulted in significantly less recurrence (11%) than conservative treatment (63%). Regardless of whether treatment was conservative or surgical, there was no significant relationship between location of the cyst and recurrence. The type of conservative treatment was not significantly related to recurrence of the cyst. The surgical recurrence rate reported here is comparable to that reported in other studies of foot and ankle ganglion cysts. The number of foot and ankle ganglion cysts evaluated in this study is the largest in the literature.

Abstract
A small group of ten patients on long-term treatment with anticoagulant drugs were offered the opportunity to attend an anticoagulation clinic run by their general practitioner over a one year period. All had previously been travelling long distances to attend over-crowded hospital clinics. Attendance at general practice clinic was excellent, control of anticoagulation was good and there were no problems advising on dose alterations. The implications of this study for the management of this and other chronic conditions in General Practice are discussed.

Abstract
A double-blind, parallel-group clinical trial was carried out in 25 patients with post-herpetic neuralgia to determine the efficacy and tolerability of a mixture of gangliosides ('Cronassial') compared with placebo. Patients were allocated at random to receive treatment with either 'Cronassial' (100 mg in 2 ml buffered solution) or placebo given by 11 subcutaneous injections over a period of 27 days, and their symptoms assessed on entry and after 2, 4 and 8 weeks. The four aspects of pain considered (overall pain, hyperaesthesia, stabbing pain and constant ache) all showed maintained reductions in severity with 'Cronassial' treatment, but not with placebo. In the case of hyperaesthesia, this difference between treatments was statistically significant (both during and after the course of injections), even with the relatively small number of patients in this study. Sleep patterns showed significant sustained improvements with 'Cronassial', but not with placebo treatment. Other psychological assessments (general psychological state, appetite and mood) showed little difference between 'Cronassial' and placebo treatment. Although 'Cronassial' was well tolerated systemically, 1 of the 12 patients was withdrawn because of general malaise, and 5 patients had local pain at the injection sites. Two of these 5 patients were withdrawn from the study. There were no withdrawals in the placebo group. It is suggested that further studies employing greater numbers of patients should be carried out to confirm the efficacy of gangliosides in improving symptoms of patients with post-herpetic neuralgia.

Abstract
Die junksies van terapeute en liggaamlike opvoedkundiges in skole vir serebraalverlamdes word omskryf. Samewerking tussen terapeute en liggaamlike opvoedkundiges in die seleksie van sportaktiwiteite en posisionering van elke serebraalverlamde kind word beklemtoon. Die adolessente en volwasse serebraalverlamde het die reg om te besluit aan watter aktiwiteite hy wil deelneem, maar moet op die nadelige gevolge en fisiese agteruitgang wat verkeerde aktiwiteite tot gevolg mag gewys word. Die voor- en nadele van verskeie sportaktiwiteite word bespreek.
