Abstract
In perennial plants such as pecan, once reproductive maturity is attained, there are genetic switches that are regulated and required for flower development year after year. Pecan trees are heterodichogamous with both pistillate and staminate flowers produced on the same tree. Therefore, defining genes exclusively responsible for pistillate inflorescence and staminate inflorescence (catkin) initiation is challenging at best. To understand these genetic switches and their timing, this study analyzed catkin bloom and gene expression of lateral buds collected from a protogynous (Wichita) and a protandrous (Western) pecan cultivar in summer, autumn and spring. Our data showed that pistillate flowers in the current season on the same shoot negatively impacted catkin production on the protogynous 'Wichita' cultivar. Whereas fruit production the previous year on 'Wichita' had a positive effect on catkin production on the same shoot the following year. However, fruiting the previous year nor current year pistillate flower production had no significant effect on catkin production on 'Western' (protandrous cultivar) cultivar. The RNA-Seq results present more significant differences between the fruiting and non-fruiting shoots of the 'Wichita' cultivar compared to the 'Western' cultivar, revealing the genetic signals likely responsible for catkin production. Our data presented here, indicates the genes showing expression for the initiation of both types of flowers the season before bloom.

Abstract
BACKGROUND Adjuvant intravesical chemotherapy following tumour resection is recommended for intermediate-risk non-muscle-invasive bladder cancer (NMIBC). OBJECTIVE To assess the efficacy and safety of adjuvant intravesical chemohyperthermia (CHT) for intermediate-risk NMIBC. DESIGN, SETTING, AND PARTICIPANTS HIVEC-II is an open-label, phase 2 randomised controlled trial of CHT versus chemotherapy alone in patients with intermediate-risk NMIBC recruited at 15 centres between May 2014 and December 2017 (ISRCTN 23639415). Randomisation was stratified by treating hospital. INTERVENTIONS Patients were randomly assigned (1:1) to adjuvant CHT with mitomycin C at 43°C or to room-temperature mitomycin C (control). Both treatment arms received six weekly instillations of 40 mg of mitomycin C lasting for 60 min. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary endpoint was 24-mo disease-free survival as determined via cystoscopy and urinary cytology. Analysis was by intention to treat. RESULTS A total of 259 patients (131 CHT vs 128 control) were randomised. At 24 mo, 42 patients (32%) in the CHT group and 49 (38%) in the control group had experienced recurrence. Disease-free survival at 24 mo was 61% (95% confidence interval [CI] 51-69%) in the CHT arm and 60% (95% CI 50-68%) in the control arm (hazard ratio [HR] 0.92, 95% CI 0.62-1.37; log-rank p = 0.8). Progression-free survival was higher in the control arm (HR 3.44, 95% CI 1.09-10.82; log-rank p = 0.02) on intention-to-treat analysis but was not significantly higher on per-protocol analysis (HR 2.87, 95% CI 0.83-9.98; log-rank p = 0.06). Overall survival was similar (HR 2.55, 95% CI 0.77-8.40; log-rank p = 0.09). Patients undergoing CHT were less likely to complete their treatment (n =75, 59% vs n = 111, 89%). Adverse events were reported by 164 patients (87 CHT vs 77 control). Major (grade III) adverse events were rare (13 CHT vs 7 control). CONCLUSIONS CHT cannot be recommended over chemotherapy alone for intermediate-risk NMIBC. Adverse events following CHT were of low grade and short-lived, although patients were less likely to complete their treatment. PATIENT SUMMARY The HIVEC-II trial investigated the role of heated chemotherapy instillations in the bladder for treatment of intermediate-risk non-muscle-invasive bladder cancer. We found no cancer control benefit from heated chemotherapy instillations over room-temperature chemotherapy. Adverse events following heated chemotherapy were low grade and short-lived, although these patients were less likely to complete their treatment.

Abstract
Fusarium oxysporum f. sp. vasinfectum race 4 (FOV4) causes an early season cotton disease including seedling deaths. This study compared two Pima cottons (Gossypium barbadense) in the infection process of FOV4 using a confocal and a scanning electron microscope. Seedlings were grown in a hydroponic system and inoculated with a virulent local FOV4 isolate. As compared with the susceptible Pima S-7, the resistant Pima PHY 841 RF had significantly fewer conidia attached and germinated on the root surface. FOV4 penetration into the root epidermis of PHY 841 RF was delayed until 24 h postinoculation (hpi) as compared with 8 hpi in Pima S-7. In Pima S-7, hyphae progressed to the xylem through the cortex between 5 and 7 days postinoculation. However, hyphae grew much slower in the cortex with no apparent hyphae observed in the xylem of PHY 841 RF. At plant maturity, no FOV4 was detected through fungal isolation and PCR in the stem of PHY 841 RF and its resistance donor parents PHY 800 and Pima S-6, as compared with Pima S-7 and DP 744 with positive results. The results demonstrate that PHY 841 RF is resistant to FOV4, due to delayed infection, reduced fungal growth and reproduction, and prevention of the fungus from invading the xylem.

Abstract
BACKGROUND Lynch syndrome is a rare familial cancer syndrome caused by pathogenic variants in the mismatch repair genes MLH1, MSH2, MSH6, or PMS2, that cause predisposition to various cancers, predominantly colorectal and endometrial cancer. Data are emerging that pathogenic variants in mismatch repair genes increase the risk of early-onset aggressive prostate cancer. The IMPACT study is prospectively assessing prostate-specific antigen (PSA) screening in men with germline mismatch repair pathogenic variants. Here, we report the usefulness of PSA screening, prostate cancer incidence, and tumour characteristics after the first screening round in men with and without these germline pathogenic variants. METHODS The IMPACT study is an international, prospective study. Men aged 40-69 years without a previous prostate cancer diagnosis and with a known germline pathogenic variant in the MLH1, MSH2, or MSH6 gene, and age-matched male controls who tested negative for a familial pathogenic variant in these genes were recruited from 34 genetic and urology clinics in eight countries, and underwent a baseline PSA screening. Men who had a PSA level higher than 3·0 ng/mL were offered a transrectal, ultrasound-guided, prostate biopsy and a histopathological analysis was done. All participants are undergoing a minimum of 5 years' annual screening. The primary endpoint was to determine the incidence, stage, and pathology of screening-detected prostate cancer in carriers of pathogenic variants compared with non-carrier controls. We used Fisher's exact test to compare the number of cases, cancer incidence, and positive predictive values of the PSA cutoff and biopsy between carriers and non-carriers and the differences between disease types (ie, cancer vs no cancer, clinically significant cancer vs no cancer). We assessed screening outcomes and tumour characteristics by pathogenic variant status. Here we present results from the first round of PSA screening in the IMPACT study. This study is registered with ClinicalTrials.gov, NCT00261456, and is now closed to accrual. FINDINGS Between Sept 28, 2012, and March 1, 2020, 828 men were recruited (644 carriers of mismatch repair pathogenic variants [204 carriers of MLH1, 305 carriers of MSH2, and 135 carriers of MSH6] and 184 non-carrier controls [65 non-carriers of MLH1, 76 non-carriers of MSH2, and 43 non-carriers of MSH6]), and in order to boost the sample size for the non-carrier control groups, we randomly selected 134 non-carriers from the BRCA1 and BRCA2 cohort of the IMPACT study, who were included in all three non-carrier cohorts. Men were predominantly of European ancestry (899 [93%] of 953 with available data), with a mean age of 52·8 years (SD 8·3). Within the first screening round, 56 (6%) men had a PSA concentration of more than 3·0 ng/mL and 35 (4%) biopsies were done. The overall incidence of prostate cancer was 1·9% (18 of 962; 95% CI 1·1-2·9). The incidence among MSH2 carriers was 4·3% (13 of 305; 95% CI 2·3-7·2), MSH2 non-carrier controls was 0·5% (one of 210; 0·0-2·6), MSH6 carriers was 3·0% (four of 135; 0·8-7·4), and none were detected among the MLH1 carriers, MLH1 non-carrier controls, and MSH6 non-carrier controls. Prostate cancer incidence, using a PSA threshold of higher than 3·0 ng/mL, was higher in MSH2 carriers than in MSH2 non-carrier controls (4·3% vs 0·5%; p=0·011) and MSH6 carriers than MSH6 non-carrier controls (3·0% vs 0%; p=0·034). The overall positive predictive value of biopsy using a PSA threshold of 3·0 ng/mL was 51·4% (95% CI 34·0-68·6), and the overall positive predictive value of a PSA threshold of 3·0 ng/mL was 32·1% (20·3-46·0). INTERPRETATION After the first screening round, carriers of MSH2 and MSH6 pathogenic variants had a higher incidence of prostate cancer compared with age-matched non-carrier controls. These findings support the use of targeted PSA screening in these men to identify those with clinically significant prostate cancer. Further annual screening rounds will need to confirm these findings.

Abstract
Abstract
Aim
There are 10,200 cases of bladder cancer diagnosed every year in the UK, accounting for 3% of all new cancer diagnoses. Robot-assisted radical cystectomy (RARC) is a minimally invasive treatment option for muscle invasive and high-risk bladder cancer with a rising uptake. Between 2017 and 2019, RARC accounted for 40.6% of all cystectomies performed in the UK, increasing to 52% in 2018 to 2019. We compared our outcomes with the best practice of RARC set by the Pasadena consensus panel in 2015.
Method
A review of the prospective database of all RARC performed by two surgeons at Royal Wolverhampton Hospital between May 2013 and October 2020 was conducted. Operative and oncological outcome data were collected from Clinical Web Portal and Somerset Cancer Register and analysed using Microsoft Excel.
Results
A total of 118 RARC were performed in the study period, 50 cases were analysed in the first audit loop and 68 cases in the second. The mean age was 69 years (44 – 82), 84% were men and 70% were ASA grade II or less. Median operating time was 376 minutes (210 – 555) and the median blood loss was 250mls. 79% of urinary diversion was intra-corporeal and 84% was ileal conduit diversion. Median length of stay was 8 days; complication rate with Clavien Dindo score of III or higher was 12.7%. 86% of our patients are still alive.
Conclusions
RARC is a safe option for the radical management of bladder cancer. Our outcomes are consistent with the Pasadena consensus recommendations.

Abstract
Introduction Patients with hepatocellular carcinoma (HCC) involving the inferior vena cava (IVC) and/or right atrium (RA) often experience debilitating symptoms, including lower extremity edema, dyspnea on exertion, shortness of breath at rest, chest pain, and ascites, that impact quality of life. The efficacy of external beam radiation therapy (EBRT) in palliating these symptoms is unclear. Thus, we sought to assess the effectiveness of EBRT in the palliation of symptoms and treatment outcomes in this patient population. Materials and methods All patients with HCC that compressed or invaded the IVC, received EBRT, and had a two-month follow-up visit to assess clinical response at our institution between 2010 and 2018 were analyzed. Patient demographics and clinical features were retrieved from the electronic medical record. Local control, local progression-free survival, and overall survival (OS) were measured from the last day of EBRT and calculated using the Kaplan-Meier method. Results Twenty-six patients with invasion or compression of the IVC were identified, 11 of whom (42%) had involvement of the RA. The median follow-up was 3.6 months. Five patients (19%) were treated with stereotactic body radiation therapy (SBRT) (all with five fractions) and 21 patients (81%) were treated with fractionated radiation therapy (range 10-16 fractions), both to a median dose of 3,000 cGy (range 2500-4000 cGy for SBRT, 2500-3750 cGy for fractionated radiation therapy). Significant proportions of patients experienced symptomatic relief from peripheral edema (54%), dyspnea on exertion (57%), shortness of breath (83%), chest pain (67%), and ascites (25%) after receiving EBRT. Additionally, they experienced few toxicities, with zero experiencing grade three or higher toxicities. One-year and two-year local control rates were 11.5% and 7.7%, respectively, and the median local progression-free survival was 4.8 months. One-year and two-year OS rates were 38.4% and 38.4%, respectively. Conclusions Our results suggest that EBRT should be considered as a potential treatment option for patients with HCC invading or compressing the IVC with or without involvement of the RA. EBRT was very well-tolerated and effectively palliated a variety of symptoms in patients with advanced disease.

Abstract
Endocrine disruptive chemicals (EDC) are known to alter thyroid function and have been associated with increased risk of certain cancers. The present study aims to provide a comprehensive overview of available studies on the association between EDC exposure and thyroid cancer. Relevant studies were identified via a literature search in the National Library of Medicine and National Institutes of Health PubMed as well as a review of reference lists of all retrieved articles and of previously published relevant reviews. Overall, the current literature suggests that exposure to certain congeners of flame retardants, polychlorinated biphenyls (PCBs), and phthalates as well as certain pesticides may potentially be associated with an increased risk of thyroid cancer. However, future research is urgently needed to evaluate the different EDCs and their potential carcinogenic effect on the thyroid gland in humans as most EDCs have been studied sporadically and results are not consistent.

Abstract
OBJECTIVES To evaluate the activity of intravesical mitomycin-C (MMC) to ablate recurrent low-risk non-muscle-invasive bladder cancer (NMIBC) and assess whether it may enable patients to avoid surgical intervention for treatment of recurrence. PATIENTS AND METHODS CALIBER is a phase II feasibility study. Participants were randomized (2:1) to treatment with four once-weekly MMC 40-mg intravesical instillations (chemoablation arm) or to surgical management. The surgical group was included to assess the feasibility of randomization. The primary endpoint was complete response to intravesical MMC in the chemoablation arm at 3 months, reported with exact 95% confidence intervals (CIs). Secondary endpoints included time to subsequent recurrence, summarized by Kaplan-Meier methods. RESULTS Between February 2015 and August 2017, 82 patients with visual diagnosis of recurrent low-risk NMIBC were enrolled from 24 UK hospitals (chemoablation, n = 54; surgical management, n =28). The median follow-up was 24 months. Complete response at 3 months was 37.0% (20/54; 95% CI 24.3-51.3) with chemoablation and 80.8% (21/26; 95% CI 60.6-93.4) with surgical management. Amongst patients with complete response at 3 months, a similar proportion was recurrence-free by 12 months in both groups (84%). Amongst those with residual disease at 3 months, the 12-month recurrence-free proportion was lower in the surgical management group (40.0%) than in the chemoablation group (84%). Recruitment stopped early as chemoablation did not meet the prespecified threshold of 45% complete responses at 3 months. CONCLUSION Intravesical chemoablation in low-risk NMIBC is feasible and safe, but did not demonstrate sufficient response in the present trial. After chemoablation there may be a reduction in recurrence rate, even in non-responders, that is greater than with surgery alone. Further research is required to investigate the role and optimal schedule of neoadjuvant intravesical chemotherapy prior to surgery for NMIBC.

Abstract
BACKGROUND Mutations in BRCA2 cause a higher risk of early-onset aggressive prostate cancer (PrCa). The IMPACT study is evaluating targeted PrCa screening using prostate-specific-antigen (PSA) in men with germline BRCA1/2 mutations. OBJECTIVE To report the utility of PSA screening, PrCa incidence, positive predictive value of PSA, biopsy, and tumour characteristics after 3 yr of screening, by BRCA status. DESIGN, SETTING, AND PARTICIPANTS Men aged 40-69 yr with a germline pathogenic BRCA1/2 mutation and male controls testing negative for a familial BRCA1/2 mutation were recruited. Participants underwent PSA screening for 3 yr, and if PSA > 3.0 ng/ml, men were offered prostate biopsy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS PSA levels, PrCa incidence, and tumour characteristics were evaluated. Statistical analyses included Poisson regression offset by person-year follow-up, chi-square tests for proportion t tests for means, and Kruskal-Wallis for medians. RESULTS AND LIMITATIONS A total of 3027 patients (2932 unique individuals) were recruited (919 BRCA1 carriers, 709 BRCA1 noncarriers, 902 BRCA2 carriers, and 497 BRCA2 noncarriers). After 3 yr of screening, 527 men had PSA > 3.0 ng/ml, 357 biopsies were performed, and 112 PrCa cases were diagnosed (31 BRCA1 carriers, 19 BRCA1 noncarriers, 47 BRCA2 carriers, and 15 BRCA2 noncarriers). Higher compliance with biopsy was observed in BRCA2 carriers compared with noncarriers (73% vs 60%). Cancer incidence rate per 1000 person years was higher in BRCA2 carriers than in noncarriers (19.4 vs 12.0; p = 0.03); BRCA2 carriers were diagnosed at a younger age (61 vs 64 yr; p = 0.04) and were more likely to have clinically significant disease than BRCA2 noncarriers (77% vs 40%; p = 0.01). No differences in age or tumour characteristics were detected between BRCA1 carriers and BRCA1 noncarriers. The 4 kallikrein marker model discriminated better (area under the curve [AUC] = 0.73) for clinically significant cancer at biopsy than PSA alone (AUC = 0.65). CONCLUSIONS After 3 yr of screening, compared with noncarriers, BRCA2 mutation carriers were associated with a higher incidence of PrCa, younger age of diagnosis, and clinically significant tumours. Therefore, systematic PSA screening is indicated for men with a BRCA2 mutation. Further follow-up is required to assess the role of screening in BRCA1 mutation carriers. PATIENT SUMMARY We demonstrate that after 3 yr of prostate-specific antigen (PSA) testing, we detect more serious prostate cancers in men with BRCA2 mutations than in those without these mutations. We recommend that male BRCA2 carriers are offered systematic PSA screening.

Abstract
This investigation aimed to extract and characterize the GCSM proteins, determine their solubility potential at two different temperatures and different solvents, and explore their functional properties. During the extraction, no water- or ethanol-soluble protein was found. Most of the protein was extracted with KOH solution. GCSM showed major protein bands between 13,273 and 56,564 Da with an isoelectric point of 5.1. The results showed that extraction temperature and solvent affected the amount of protein extracted from GCSM. The highest protein yield (63.4%) was obtained with KOH at 55 °C. Fat content negatively affected the protein solubility. The highest protein purity (99.9%) was obtained with 6% of fat content and the lowest one with 19% of fat content. GCSM has a high glutamic acid content, followed by arginine and aspartic acid compared to the other amino acids. The essential amino acids make up about 30.0% of the total amino acid concentration in KOH-soluble fractions. The results showed a denaturation temperature of GCSM protein ranging from 61.4 to 63.6 °C. Scanning electron microscopy reveals a microglobular protein structure. GCSM protein isolate showed lower (P < 0.05) water-holding and oil-holding capacity but similar gelation properties as soy protein. GCSM protein shows a high foaming capacity at high pH values and high emulsion stability. PRACTICAL APPLICATION: The results of this investigation have a direct impact on the plant protein processing industry. This paper presents a new source of plant protein with a high foaming capacity in alkaline conditions with potential applications for human consumption and feed for aquaculture and animals. The results of this research may impact the cotton producers who can increase their income, and the aquaculture industry will have a cheaper source of protein that can partially substitute the expensive fishmeal. Cottonseed protein can be used to develop high protein extruded snacks and other functional foods, such as plant protein-based food products.

Abstract
Intravascular papillary endothelial hyperplasia (IPEH) is a benign, highly vascularized, endothelial growth that can be mischaracterized as a malignancy. While hundreds of IPEH cases are reported, only four occurred in the maxillary sinus. We present the case of a 28-year-old male who underwent surgical resection of IPEH of the right maxillary sinus. An additional consideration was the patient's condition of univentricular tricuspid atresia which contributed to chronic hypoxemia and polycythemia. After complete resection from the maxillary sinus, post-operational workup determined the lesion to be IPEH. Given the potential for misdiagnosis of IPEH, careful histopathologic evaluation is required in order to avoid improper treatment.

Abstract
With increasing experience, more complex patients are undergoing robotic surgery but the patient safety during these procedures remains paramount. Being a relatively recent technique of minimal access surgery, the safety and feasibility of robotic surgery is still under scrutiny. We recently performed two robotic procedures in patients who have permanent cardiac pacemaker. We believe this is the first published report through which it is shared and discussed, the preoperative and intraoperative management for these patients along with the importance of WHO checklist for safely performing robotic procedures. The importance of pre-procedure planning and briefing cannot be emphasised enough as these along with intraoperative management remain the key step in dealing with an adverse cardiac event due to permanent pacemaker malfunction.

Abstract
The development and implementation of barbed sutures has transformed the technique of tissue closure with increasing application across multiple surgical disciplines. Changes in design and handling such as the introduction of absorbable and non-absorbable bidirectional barbed sutures reflect an increasing applicability in tissues of varying qualities. We undertook a comprehensive review of available literature to provide an evidence-based rationale for the clinical use of barbed suture tissue closure devices. We summarise uses along with advantages and disadvantages reported across a number of surgical specialties such as urology, orthopaedics, gynaecology and plastic surgery. Tangible benefits noted were faster closure speed, maintenance of suture integrity, improved efficiency in closure, avoidance of knots and possibly a cost-benefit effect. In terms of complications, the barbed sutures compared equally with standard sutures with no significant differences. In conclusion, barbed sutures have demonstrated versatility and safety across surgical specialties and compares favourably with standard sutures. There appears to be an increasing popularity in the use of barbed sutures with clear advantages to both surgeon and patient.

Abstract
Britain's lagging economic performance is clearly tied to a failure on the part of British industry to innovate to the same extent as competitor economies. There is a spatial coincidence between the least innovative parts of Britain's innovation-poor economy and the traditionally depressed industrial regions. It has been suggested in government and academia that one way to help overcome both the problem of innovation lag and that of regional industrial decline is for Britain to adopt a regional innovation policy. In this paper the case for this is discussed in the context of the regional problem and in terms of problems posed by a market-led innovation process. A critical evaluation of one possible form of regional innovation policy based on the decentralisation of government research and development as carried out in France since the 1950s is presented. It is concluded that neither the present British nor French approaches are ideal but that some regionalised combination of them could be an improvement.

Abstract
'UCB-1' (Pistacia atlantica × Pistacia integerrima) rootstock is a hybrid cultivar widely used by the U.S. pistachio industry. In the last three years, a large number of micropropagated UCB-1 pistachio rootstocks planted in California and Arizona orchards exhibited shortened internodes, stunted growth, swollen lateral buds, bushy/bunchy growth, stem galls with multiple buds, and twisted roots with minimal lateral branching. Field T-budding success in affected orchards was reduced to approximately 30% with unusual bark cracking often observed around the bud-union. The percentage of abnormal rootstocks within affected orchards varied from 10 to 90%. We have termed the cumulative symptoms "pistachio bushy top syndrome" (PBTS) to describe these affected trees. Two isolates, both containing virulence factors from the phytopathogen Rhodococcus fascians, were identified on symptomatic trees in field and nursery samples. Micropropagated UCB-1 trees inoculated with the Rhodococcus isolates exhibited stunted growth, shortened internode length, swollen lateral buds, sylleptic branching, and differences in root morphology, compared with control UCB-1 trees. To our knowledge, this is the first report of Rhodococcus isolates, related to Rhodococcus fascians, causing disease on a commercial tree crop and the results presented indicate that this organism is responsible at least in part for PBTS in California and Arizona.

Abstract
An in situ transesterification approach was demonstrated for converting lipid-rich wet algae (Nannochloropsis salina) into fatty acid ethyl esters (FAEE) under microwave-mediated supercritical ethanol conditions, while preserving the nutrients and other valuable components in the algae. This single-step process can simultaneously and effectively extract the lipids from wet algae and transesterify them into crude biodiesel. Experimental runs were designed to optimize the process parameters and to evaluate their effects on algal biodiesel yield. The algal biomass characterization and algal biodiesel analysis were carried out by using various analytical instruments such as FTIR, SEM-EDS, TLC, GC-MS and transmission electron microscopy (TEM). The thermogravimetric analysis (TGA) under nitrogen and oxygen environments was also performed to examine the thermal and oxidative stability of ethyl esters produced from wet algae. This simple in situ transesterification process using a green solvent and catalyst-free approach can be a potentially efficient route for algal biodiesel production.

Abstract
The effect of a "controlled temperature" approach was investigated in the microwave-enhanced simultaneous extraction and transesterification of dry algae. Experimental runs were designed using a response surface methodology (RSM). The process parameters such as dry algae to methanol ratio, reaction time, and catalyst concentrations were optimized to evaluate their effects on the fatty acid methyl ester (FAME) yield under the "controlled temperature" conditions. Thermal energy associated with the microwave transesterification process was calculated at various temperature levels using the optimized process parameters. Algal biomass characterization and algal biodiesel analysis were carried out using various analytical instruments such as FTIR, TEM, GC-MS and confocal laser scanning microscopy. Thermogravimetric analysis under both nitrogen and oxygen environments was performed to examine the thermal and oxidative stability of the algal fatty acid methyl esters.

Abstract
Objectives The Manchester–Oxford Foot Questionnaire (MOXFQ) is a validated
16-item, patient-reported outcome measure for evaluating outcomes
of foot or ankle surgery. The original development of the instrument
identified three domains. This present study examined whether the
three domains could legitimately be summed to provide a single summary
index score. Methods The MOXFQ and Short-Form (SF)-36 were administered to 671 patients
before surgery of the foot or ankle. Data from the three domains
of the MOXFQ (pain, walking/standing and social interaction) were
subjected to higher order factor analysis. Reliability and validity
of the summary index score was assessed. Results The mean age of the participants was 52.8 years (sd 15.68;
18 to 89). Higher order principle components factor analysis produced
one factor, accounting for 74.7% of the variance. The newly derived
single index score was found to be internally reliable (α = 0.93)
and valid, achieving at least moderate correlations (r ≥ 0.5, p
< 0.001) with related (pain/function) domains of the SF-36. Conclusions Analyses indicated that data from the MOXFQ can be presented
in summary form. The MOXFQ summary index score (MOXFQ-Index) provides
an overall indication of the outcomes of foot and ankle surgery.
Furthermore, the single index reduces the number of statistical
comparisons, and hence the role of chance, when exploring MOXFQ
data.

Abstract
The responsiveness of the Manchester-Oxford Foot Questionnaire (MOXFQ) was compared with foot/ankle-specific and generic outcome measures used to assess all surgery of the foot and ankle. We recruited 671 consecutive adult patients awaiting foot or ankle surgery, of whom 427 (63.6%) were female, with a mean age of 52.8 years (18 to 89). They independently completed the MOXFQ, Short-Form 36 (SF-36) and EuroQol (EQ-5D) questionnaires pre-operatively and at a mean of nine months (3.8 to 14.4) post-operatively. Foot/ankle surgeons assessed American Orthopaedic Foot and Ankle Society (AOFAS) scores corresponding to four foot/ankle regions. A transition item measured perceived changes in foot/ankle problems post-surgery. Of 628 eligible patients proceeding to surgery, 491 (78%) completed questionnaires and 262 (42%) received clinical assessments both pre- and post-operatively. The regions receiving surgery were: multiple/whole foot in eight (1.3%), ankle/hindfoot in 292 (46.5%), mid-foot in 21 (3.3%), hallux in 196 (31.2%), and lesser toes in 111 (17.7%). Foot/ankle-specific MOXFQ, AOFAS and EQ-5D domains produced larger effect sizes (> 0.8) than any SF-36 domains, suggesting superior responsiveness. In analyses that anchored change in scores and effect sizes to patients' responses to a transition item about their foot/ankle problems, the MOXFQ performed well. The SF-36 and EQ-5D performed poorly. Similar analyses, conducted within foot-region based sub-groups of patients, found that the responsiveness of the MOXFQ was good compared with the AOFAS. This evidence supports the MOXFQ's suitability for assessing all foot and ankle surgery.

Abstract
We report an interesting and rare case of a vesicocutaneous fistula, which was diagnosed only one year following radiotherapy. A 71 year old gentleman presented with a gangrenous swelling of his left thigh. A copius amount of urine was seen to be draining from the site after initial incision and drainage. Computed tomography with contrast confirmed the diagnosis of a vesicocutaneous fistula. Bilateral nephrostomies were inserted to aid spontaneous closure of the fistula. Previous case reports of vesicocutaneous fistulae involving radiotherapy have described the complication of a fistula occurring many years after the intervention.

Abstract
Previously validated for hallux valgus surgery, the Manchester-Oxford Foot Questionnaire (MOXFQ) is here evaluated for use with different regions of the foot and ankle. The study recruited 671 consecutive patients (87.8% of those eligible), mean age 52.8 years, 64% female, who completed the MOXFQ and SF-36 general health survey before foot or ankle surgery. Surgeons completed the American Orthopaedic Foot & Ankle Society (AOFAS) scales and indicated that the patients' main regions for surgery were: Hallux 210 (31.3%), Lesser toes 119 (17.7%), Mid foot 22 (3.3%), Ankle/hind foot 311 (46.3%), Multiple/whole foot 9 (1.3%). Individual MOXFQ items were assessed in terms of response rate and floor/ceiling effects, with the validity of the three MOXFQ scales (Walking/standing, Pain, and Social interaction) being assessed in terms of item-total correlations, internal and test-retest reliability, and construct validity. MOXFQ item response rates were high (all >98%). Cronbach's alphas of >0.7 confirmed internal consistency of all three scales. Test-retest ICCs were all ≥0.89. Correlations of >0.4 obtained with related SF-36 and AOFAS scales supported a priori hypotheses. Good measurement properties are confirmed for the MOXFQ in the context of baseline assessment of patients receiving surgery for a variety of foot or ankle problems.

Abstract
Microbial diversity associated with micropropagated Atriplex species was assessed using microscopy, isolate culturing, and sequencing. Light, electron, and confocal microscopy revealed microbial cells in aseptically regenerated leaves and roots. Clone libraries and tag-encoded FLX amplicon pyrosequencing (TEFAP) analysis amplified sequences from callus homologous to diverse fungal and bacterial taxa. Culturing isolated some seed borne endophyte taxa which could be readily propagated apart from the host. Microbial cells were observed within biofilm-like residues associated with plant cell surfaces and intercellular spaces. Various universal primers amplified both plant and microbial sequences, with different primers revealing different patterns of fungal diversity. Bacterial and fungal TEFAP followed by alignment with sequences from curated databases revealed 7 bacterial and 17 ascomycete taxa in A. canescens, and 5 bacterial taxa in A. torreyi. Additional diversity was observed among isolates and clone libraries. Micropropagated Atriplex retains a complex, intimately associated microbiome which includes diverse strains well poised to interact in manners that influence host physiology. Microbiome analysis was facilitated by high throughput sequencing methods, but primer biases continue to limit recovery of diverse sequences from even moderately complex communities.

Abstract
This study demonstrated a one-step process for direct liquefaction and conversion of wet algal biomass containing about 90% of water to biodiesel under supercritical methanol conditions. This one-step process enables simultaneous extraction and transesterification of wet algal biomass. The process conditions are milder than those required for pyrolysis and prevent the formation of by-products. In the proposed process, fatty acid methyl esters (FAMEs) can be produced from polar phospholipids, free fatty acids, and triglycerides. A response surface methodology (RSM) was used to analyze the influence of the three process variables, namely, the wet algae to methanol (wt./vol.) ratio, the reaction temperature, and the reaction time, on the FAMEs conversion. Algal biodiesel samples were analyzed by ATR-FTIR and GC-MS. Based on the experimental analysis and RSM study, optimal conditions for this process are reported as: wet algae to methanol (wt./vol.) ratio of around 1:9, reaction temperature and time of about 255 °C, and 25 min respectively. This single-step process can potentially be an energy efficient and economical route for algal biodiesel production.

Abstract
The effect of microwave irradiation on the simultaneous extraction and transesterification (in situ transesterification) of dry algal biomass to biodiesel was investigated. A high degree of oil/lipid extraction from dry algal biomass and an efficient conversion of the oils/lipids to biodiesel were demonstrated in a set of well-designed experimental runs. A response surface methodology (RSM) was used to analyze the influence of the process variables (dry algae to methanol (wt/vol) ratio, catalyst concentration, and reaction time) on the fatty acid methyl ester conversion. Based on the experimental results and RSM analysis, the optimal conditions for this process were determined as: dry algae to methanol (wt/vol) ratio of around 1:12, catalyst concentration about 2 wt.%, and reaction time of 4 min. The algal biodiesel samples were analyzed with GC-MS and thin layer chromatography (TLC) methods. Transmission electron microscopy (TEM) images of the algal biomass samples before and after the extraction/transesterification reaction are also presented.

Abstract
OBJECTIVE The purpose of this study was to investigate the efficacy and tolerance of an additional phosphate enema prior to non-laxative CT colonography (CTC). METHODS 71 patients (mean age 80 years, 28 male, 43 female) underwent non-laxative CTC following 4 oral doses of diluted 2% w/w barium sulphate. Patients were invited to self-administer a phosphate enema 2 h before CTC. An experienced observer graded the volume of retained stool (1 (nil) to 4 (>75% bowel circumference coated)), retained fluid ((1 (nil) to 4 (>50% circumference obscured)), retained stool tagging quality (1 (untagged) to 5 (≥75% to 100%) tagged) and confidence a polyp ≥6 mm could be excluded (yes/no) for each of six colonic segments. Tolerance of the enema was assessed via questionnaire. Data were analysed between those using and not using the enema by Mann-Whitney and Fisher's exact test. 18/71 patients declined the enema. RESULTS There was no reduction in residual stool volume with enema use compared with non-use either overall (mean score 2.6 vs 2.7, p = 0.76) or in the left colon (mean 2.3 vs 2.4, p = 0.47). Overall tagging quality was no different (mean score 4.4 vs 4.3, p = 0.43). There was significantly more retained left colonic fluid post enema (mean score 1.9 vs 1.1, p<0.0001), and diagnostic confidence in excluding polyps was significantly reduced (exclusion not possible in 35% segments vs 21% without enema, p = 0.006). Of 53 patients, 30 (56%) found the enema straightforward to use, but 4 (8%) found it unpleasant. CONCLUSION Phosphate enema use prior to non-laxative CTC leads to greater retained fluid, reducing diagnostic confidence, and is not recommended.

Abstract
Aboriginal land managers have observed that feral Asian water buffalo (Bubalis bubalis Lydekker) are threatening the ecological and cultural integrity of perennial freshwater sources in Arnhem Land, Australia. Here we present collaborative research between the Aboriginal Rangers from Warddeken Land Management Limited and Western scientists which quantified the ground-level impacts of buffalo on seven perennial freshwater springs of the Arnhem Plateau. A secondary aim was to build the capacity of Aboriginal Rangers to self-monitor and evaluate the ecological outcomes of their land management activities. Sites with high buffalo abundance had significantly different ground, ground cover, and water quality attributes compared to sites with low buffalo abundance. The low buffalo abundance sites were characterized by tall herbaceous vegetation and flat ground, whereas wallows, bare ground, and short ungrazed grasses were indicators of sites with high buffalo abundance. Water turbidity was greater when buffalo abundance was high. The newly acquired monitoring skills and derived indicators of buffalo damage will be used by Aboriginal Rangers to assess the ecological outcomes of their future buffalo control efforts on the Arnhem Plateau.

Abstract
Germination and early seedling development are coordinately regulated by glucose and phytohormones such as ABA, GA, and ethylene. However, the molecules that affect plant responses to glucose and phytohormones remain to be fully elucidated. Eukaryotic release factor 1 (eRF1) is responsible for the recognition of the stop codons in mRNAs during protein synthesis. Accumulating evidence indicates that eRF1 functions in other processes in addition to translation termination. The physiological role of eRF1-2, a member of the eRF1 family, in Arabidopsis was examined here. The eRF1-2 gene was found to be specifically induced by glucose. Arabidopsis plants overexpressing eRF1-2 were hypersensitive to glucose during germination and early seedling development. Such hypersensitivity to glucose was accompanied by a dramatic reduction of the expression of glucose-regulated genes, chlorophyll a/b binding protein and plastocyanin. The hypersensitive response was not due to the enhanced accumulation of ABA. In addition, the eRF1-2 overexpressing plants showed increased sensitivity to paclobutrazol, an inhibitor of GA biosynthesis, and exogenous GA restored their normal growth. By contrast, the loss-of-function erf1-2 mutant exhibited resistance to paclobutrazol, suggesting that eRF1-2 may exert a negative effect on the GA signalling pathway. Collectively, these data provide evidence in support of a novel role of eRF1-2 in affecting glucose and phytohormone responses in modulating plant growth and development.

Abstract
The thermostability of nisin and Nisaplin® was investigated in the presence and absence of pectin. By mixing with pectin, both nisin and Nisaplin® were able to inhibit microbial growth, even after heating to 433 K. In contrast, without pectin, the nisin was totally inactivated after heat treatment. Nisin and pectin in solution were complexed, as shown by atomic force microscopic analysis. Probably, the complex formation between the polysaccharide and the polypeptide improves the nisin thermostability; however, a detailed mechanism remains to be resolved. Thin membranes were prepared by co-extrusion of poly(lactic acid) and microparticles of pectin-Nisaplin®. Despite the high extrusion temperatures, the presence of pectin protected the biological activity of nisin and the resultant membranes were antimicrobial and could be used as an inner layer of multi-layer packaging materials for active packaging.

Abstract
A new medium designated Liber A has been designed and used to successfully cultivate all three 'Candidatus Liberibacter spp.,' the suspect causative agents of huanglongbing (HLB) in citrus. The medium containing citrus vein extract and a growth factor sustained growth of 'Ca. Liberibacter spp.' for four or five single-colony transfers before viability declined. Colonies, positive for 'Ca. L. asiaticus' by a 16s-based rDNA real-time polymerase chain reaction (RT-PCR) assay and sequencing, were irregular-shaped, convex, and 0.1 to 0.3 mm after 3 to 4 days. Suspect 'Ca. L. asiaticus' and 'Ca. L. americanus' cells were observed in infected tissue and on agar culture by scanning electron microscopy. The cells were ovoid to rod shaped, 0.3 to 0.4 by 0.5 to 2.0 microm, often with fimbriae-like appendages. Two strains of 'Ca. L. asiaticus' and one of 'Ca. L. americanus' grown on Liber A medium were pathogenic on citrus and could be isolated from noninoculated tissues of inoculated trees and seedlings 9 and 2 months later, respectively. The identity was confirmed by RT-PCR and 16s rDNA sequencing. This is the first report of the cultivation and pathogenicity of 'Ca. L. asiaticus' and 'Ca. L. americanus' associated with symptoms of HLB.
