Abstract
The currently available distribution and range maps for the Great Grey Owl (GGOW; Strix nebulosa) are ambiguous, contradictory, imprecise, outdated, often hand-drawn and thus not quantified, not based on data or scientific. In this study, we present a proof of concept with a biological application for technical and biological workflow progress on latest global open access 'Big Data' sharing, Open-source methods of R and geographic information systems (OGIS and QGIS) assessed with six recent multi-evidence citizen-science sightings of the GGOW. This proposed workflow can be applied for quantified inference for any species-habitat model such as typically applied with species distribution models (SDMs). Using Random Forest-an ensemble-type model of Machine Learning following Leo Breiman's approach of inference from predictions-we present a Super SDM for GGOWs in Alaska running on Oracle Cloud Infrastructure (OCI). These Super SDMs were based on best publicly available data (410 occurrences + 1% new assessment sightings) and over 100 environmental GIS habitat predictors ('Big Data'). The compiled global open access data and the associated workflow overcome for the first time the limitations of traditionally used PC and laptops. It breaks new ground and has real-world implications for conservation and land management for GGOW, for Alaska, and for other species worldwide as a 'new' baseline. As this research field remains dynamic, Super SDMs can have limits, are not the ultimate and final statement on species-habitat associations yet, but they summarize all publicly available data and information on a topic in a quantified and testable fashion allowing fine-tuning and improvements as needed. At minimum, they allow for low-cost rapid assessment and a great leap forward to be more ecological and inclusive of all information at-hand. Using GGOWs, here we aim to correct the perception of this species towards a more inclusive, holistic, and scientifically correct assessment of this urban-adapted owl in the Anthropocene, rather than a mysterious wilderness-inhabiting species (aka 'Phantom of the North'). Such a Super SDM was never created for any bird species before and opens new perspectives for impact assessment policy and global sustainability.

Abstract
OBJECTIVE This study aimed to discuss the role of large cavity functional endoscopic sinus surgery in the management of chronic rhinosinusitis with nasal polyps in patients with non-steroidal anti-inflammatory drug exacerbated respiratory disease. METHODS This was a retrospective review of patients undergoing large cavity functional endoscopic sinus surgery for non-steroidal anti-inflammatory drug exacerbated respiratory disease from January 2016 to March 2022. Population characteristics, pre- and post-operative number of functional endoscopic sinus surgical procedures, endoscopic polyp grade, Lund-Mackay score and nasal symptoms were recorded. RESULTS Thirteen consecutive patients with a median age of 47 years were included. They all failed maximal medical treatment and/or conservative functional endoscopic sinus surgery and underwent large cavity sinus surgery followed by post-operative maximal medical therapy. All patients showed an improvement in nasal symptoms with improved Lund-Mackay scores post-operatively. The median length of follow up was 1.5 years. CONCLUSION Large cavity functional endoscopic sinus surgery seems to halt the progression of chronic rhinosinusitis with nasal polyps in non-steroidal anti-inflammatory drug exacerbated respiratory disease. In this case series, large cavity functional endoscopic sinus surgery combined with optimal post-operative medical treatment appeared to switch off chronic rhinosinusitis with nasal polyps in patients with non-steroidal anti-inflammatory drug exacerbated respiratory disease.

Abstract
BACKGROUND AND OBJECTIVE CINtec PLUS and cobas HPV tests (Roche) were previously ascertained for triaging an LSIL referral population [1]. As part of this study, genotype-specific distribution and attributable risk of high-risk (HR)-HPV in cervical intraepithelial neoplasia (CIN) were determined. METHODS Archived cervical specimens in ThinPrep PreservCyt (Hologic Inc) from the LSIL referral population (n= 533) were genotyped using the Anyplex II HPV HR test (Anyplex, Seegene Inc). Since the study specimens had been in storage in ambient temperature for 31-47 months since collection, Anyplex results were compared with that of the initial cobas testing of fresh specimens to validate the suitability and stability of specimens for the present study. RESULTS Overall, Anyplex test was positive in 63% (336/533) vs. 55.7% (297/533) for cobas test. Anyplex test performed identical to cobas test identifying 93.2% (82/88) of ⩾CIN2/adenocarcinoma in situ (AIS). Anyplex test detected genotypes 16/18 in 15.7% (36/230) ⩽CIN1 vs. 45.5% (40/88) ⩾CIN2/AIS; the corresponding figures were 13.5% (31/230) and 45.5% (40/48) for the cobas test. Genotype 16 showed increasing attribution, 13.2% in CIN1, 27.1% in CIN2 and 40% in CIN3/AIS. Of the 12 other high-risk (OHR) types collectively identified by cobas, Anyplex test specifically detected, in decreasing order, genotypes 51, 31, 35, 56, 39, and 45 as the most frequent types, often in multiple-type infections, in 64.8% ⩾CIN2. Regardless, estimated attribution was evident for each of the 12 OHR types in ⩾CIN2. Multiple-type infections were more frequent than single-type infections in all CIN grades. CONCLUSIONS Attributable risk of all HR-HPV genotypes targeted by both Anyplex and cobas tests was evident in ⩾CIN2/AIS Testing for these genotypes in HPV primary cervical screening and cytology triage could identify those at increased risk of cervical cancer and also be beneficial in the management of LSIL referral populations.

Abstract
The relationship of evolution with diet and environment can provide insights into modern disease. Fossil evidence shows apes, and early human ancestors were fruit eaters living in environments with strongly seasonal climates. Rapid cooling at the end of the Middle Miocene (15-12 Ma: millions of years ago) increased seasonality in Africa and Europe, and ape survival may be linked with a mutation in uric acid metabolism. Climate stabilized in the later Miocene and Pliocene (12-5 Ma), and fossil apes and early hominins were both adapted for life on ground and in trees. Around 2.5 Ma, early species of Homo introduced more animal products into their diet, and this coincided with developing bipedalism, stone tool technology and increase in brain size. Early species of Homo such as Homo habilis still lived in woodland habitats, and the major habitat shift in human evolution occurred at 1.8 Ma with the origin of Homo erectus. Homo erectus had increased body size, greater hunting skills, a diet rich in meat, control of fire and understanding about cooking food, and moved from woodland to savannah. Group size may also have increased at the same time, facilitating the transmission of knowledge from one generation to the next. The earliest fossils of Homo sapiens appeared about 300 kyr, but they had separated from Neanderthals by 480 kyr or earlier. Their diet shifted towards grain-based foods about 100 kyr ago, and settled agriculture developed about 10 kyr ago. This pattern remains for many populations to this day and provides important insights into current burden of lifestyle diseases.

Abstract
Mass extinctions occur frequently in natural history. While studies of animals that became extinct can be informative, it is the survivors that provide clues for mechanisms of adaptation when conditions are adverse. Here, we describe a survival pathway used by many species as a means for providing adequate fuel and water, while also providing protection from a decrease in oxygen availability. Fructose, whether supplied in the diet (primarily fruits and honey), or endogenously (via activation of the polyol pathway), preferentially shifts the organism towards the storing of fuel (fat, glycogen) that can be used to provide energy and water at a later date. Fructose causes sodium retention and raises blood pressure and likely helped survival in the setting of dehydration or salt deprivation. By shifting energy production from the mitochondria to glycolysis, fructose reduced oxygen demands to aid survival in situations where oxygen availability is low. The actions of fructose are driven in part by vasopressin and the generation of uric acid. Twice in history, mutations occurred during periods of mass extinction that enhanced the activity of fructose to generate fat, with the first being a mutation in vitamin C metabolism during the Cretaceous-Paleogene extinction (65 million years ago) and the second being a mutation in uricase that occurred during the Middle Miocene disruption (12-14 million years ago). Today, the excessive intake of fructose due to the availability of refined sugar and high-fructose corn syrup is driving 'burden of life style' diseases, including obesity, diabetes and high blood pressure.

Abstract
Functional plasticity of the adult brain is well established. Recently, the structural counterpart to such plasticity has been suggested by neuroimaging studies showing experience-dependent differences in gray matter (GM) volumes. Within the primary and secondary olfactory cortices, reduced GM volumes have been demonstrated in patients with olfactory loss. However, these cross-sectional studies do not provide causal evidence for GM volume change, and thereby structural plasticity. Disorders of the peripheral olfactory system, such as chronic rhinosinusitis (CRS), provide an ideal model to study GM structural plasticity, given that patients may experience long periods of olfactory impairment, followed by near complete recovery with treatment. We therefore performed a prospective longitudinal study in patients undergoing surgical treatment for CRS. We used voxel-based morphometry (VBM) to investigate GM volume change in 12 patients (M:F = 7:5; 47.2 ± 14.9 years), 3 months post-op. There was a significant improvement in olfactory function according to birhinal psychophysical testing. We performed a voxel-wise region of interest analysis, with significance corrected for number of regions (p < 0.0036corr). We found significantly increased post-operative GM volumes within the primary (left piriform cortex, right amygdala) and secondary (right orbitofrontal cortex, caudate nucleus, hippocampal-parahippocampal complex and bilateral temporal poles) olfactory networks, and decreased GM volumes within the secondary network only (left caudate nucleus and temporal pole, bilateral hippocampal-parahippocampal complex). As a control measure, we assessed GM change within V1, S1 and A1, where there were no suprathreshold voxels. To our knowledge, this is the first study to demonstrate GM structural plasticity within the primary and secondary olfactory cortices, following restoration of olfaction.

Abstract
Background Olfactory dysfunction is an increasingly recognised condition, associated with reduced quality of life and major
health outcomes such as neurodegeneration and death. However, translational research in this field is limited by heterogeneity in methodological approach, including definitions of impairment, improvement and appropriate assessment techniques. Accordingly, effective treatments for smell loss are limited. In an effort to encourage high quality and comparable work in this field, among others, we propose the following ideas and recommendations. Whilst the full set of recommendations are outlined in the main document, points include the following:
• Patients with suspected olfactory loss should undergo a full examination of the head and neck, including rigid nasal endoscopy
with small diameter endoscopes.
• Subjective olfactory assessment should not be undertaken in isolation, given its poor reliability.
• Psychophysical assessment tools used in clinical and research settings should include reliable and validated tests of odour
threshold, and/or one of odour identification or discrimination.
• Comprehensive chemosensory assessment should include gustatory screening.
• Smell training can be helpful in patients with olfactory loss of several aetiologies. Conclusions We hope the current manuscript will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency and generalisability of work in this field.

Abstract
AIMS Prostate cancer (PrCa) is the most frequently diagnosed non-cutaneous cancer in men. Without clear pathological indicators of disease trajectory at diagnosis, management of PrCa is challenging, given its wide-ranging manifestation from indolent to highly aggressive disease. This study examines the role in PrCa of the Pygopus (PYGO)2 chromatin effector protein as a risk stratification marker in PrCa. METHODS RNA expression was performed in PrCa cell lines using Northern and RT-PCR analyses. Protein levels were assessed using immunoblot and immunofluorescence. Immunohistochemistry was performed on tissue microarrays constructed from radical prostatectomies with 5-year patient follow-up data including Gleason score tumour staging, margin and lymph node involvement and prostate serum antigen (PSA) levels. Biochemical recurrence (BR) was defined as a postoperative PSA level of >0.2 nL. Univariate and multivariate analyses were performed using SAS and Kaplan-Meier curves using graphPad (Prism). RESULTS In vitro depletion of PYGO2 by RNAi in both androgen receptor positive and negative PrCa cell lines attenuated growth and reduced Ki67 and 47S rRNA expression, while PYGO2 protein was localised to the nuclei of tumours as determined by immunohistochemistry. High expression levels of PYGO2 in tumours (n=156) were correlated with BR identified as PSA progression, after 7-year follow-up independent of other traditional risk factors. Most importantly, high PYGO2 levels in intermediate grade tumours suggested increased risk of recurrence over those with negative or weak expression. CONCLUSION Our data suggest that elevated PYGO2 expression in primary prostate adenocarcinoma is a potential risk factor for BR.

Abstract
BACKGROUND There has been a great expansion in patient-based outcome measures to face the ever-increasing demand to demonstrate surgical efficacy. However, surgeons have not adopted until now any systematic outcome instrument. The 22-item Sino-Nasal Outcome Test (SNOT-22) is a validated sinonasal outcome score in sinonasal and septorhinoplasty surgery but does not measure aesthetic outcome. The aim of this paper is to validate a modification to the Sino-Nasal Outcomes Test-22 (SNOT-22) with a new question regarding the shape of the nose (SNOT-23). METHODOLOGY We conducted a prospective cohort study on 69 consecutive patients undergoing septorhinoplasty and a control group of healthy volunteers. Reproducibility, responsiveness to treatment, known group differences and validity of the SNOT-23 were analysed. Scores were compared to visual analogue scales, nasal obstruction symptoms evaluation (NOSE) score and nasal inspiratory peak flow. RESULTS SNOT-23 has good test-retest reliability and is a valid outcome measure for assessing response to surgery especially with regards to shape of the nose and nasal obstruction when compared to other patient reported measures. CONCLUSION SNOT-23 is a valid and reliable tool that can be easily used in routine clinical practice to assess the functional and aesthetic outcomes from septorhinoplasty surgery. The SNOT-23 could be adopted as a universal, easy to use tool in rhinology clinics for the assessment of response to septorhinoplasty and sinus surgery.

Abstract
BACKGROUND Olfactory dysfunction is an increasingly recognised condition, associated with reduced quality of life and major health outcomes such as neurodegeneration and death. However, translational research in this field is limited by heterogeneity in methodological approach, including definitions of impairment, improvement and appropriate assessment techniques. Accordingly, effective treatments for smell loss are limited. In an effort to encourage high quality and comparable work in this field, among others, we propose the following ideas and recommendations. Whilst the full set of recommendations are outlined in the main document, points include the following: - Patients with suspected olfactory loss should undergo a full examination of the head and neck, including rigid nasal endoscopy with small diameter endoscopes. - Subjective olfactory assessment should not be undertaken in isolation, given its poor reliability. - Psychophysical assessment tools used in clinical and research settings should include reliable and validated tests of odour threshold, and/or one of odour identification or discrimination. - Comprehensive chemosensory assessment should include gustatory screening. - Smell training can be helpful in patients with olfactory loss of several aetiologies. CONCLUSIONS We hope the current manuscript will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency and generalisability of work in this field.

Abstract
This tutorial promotes good practice for exploring the rationale of systems pharmacology models. A safety systems engineering inspired notation approach provides much needed rigor and transparency in development and application of models for therapeutic discovery and design of intervention strategies. Structured arguments over a model's development, underpinning biological knowledge, and analyses of model behaviors are constructed to determine the confidence that a model is fit for the purpose for which it will be applied.

Abstract
OBJECTIVES Free calcium plays an integral role in peripheral olfactory processing, including feedback inhibition. It has therefore been suggested that reduction of intranasal free calcium with buffer solutions such as sodium citrate may improve olfactory function in patients with smell impairment. Several previous studies have supported this hypothesis, particularly in post-infectious olfactory loss. We therefore aimed to determine whether treatment with intranasal sodium citrate improves olfactory function in patients with post-infectious impairment. DESIGN Prospective, single-blind, placebo-controlled trial. SETTING Interdisciplinary Smell and Taste Clinic, TU Dresden (tertiary referral centre). PARTICIPANTS Forty-nine adult participants with post-infectious olfactory impairment (M : F = 11 : 38, mean age 58.71 ± 11.03 years). MAIN OUTCOME MEASURES Olfactory function (odour threshold and identification) before and after treatment as determined using "Sniffin' Sticks". Patients were treated monorhinally with 1 mL sodium citrate solution. The contralateral nasal cavity was treated with 1 mL physiological sodium chloride solution, which acted as internal control. Clinical improvement was assumed where threshold or identification score increased by ≥2.5 or 3 points, respectively, or ≥5.5 points together. RESULTS We demonstrated a statistically significant improvement in composite threshold + identification scores following treatment with sodium citrate, compared with placebo. This was true for all patients (mean improvement 0.87 ± 2.68 points, P = 0.04), and on subgroup analysis in those with hyposmia (mean improvement 1.15 ± 2.37 points, P = 0.02). However, the effect size did not reach clinical significance. CONCLUSIONS Further basic and clinical work is required to fully delineate the effect of intranasal sodium citrate in the treatment of post-infectious olfactory loss.

Abstract
OBJECTIVE Body dysmorphic disorder (BDD) is defined as having a preoccupation with a perceived flaw in one's appearance, which appears slight to others and significantly interferes with a person's functioning. When undetected in septorhinoplasty patients, it will often lead to poor outcomes. DESIGN We performed a prospective cohort study to determine the prevalence of BDD in our patients and whether surgical correction could be considered. SETTING AND PARTICIPANTS We recruited 34 patients being considered for septorhinoplasty in a tertiary referral rhinology clinic and a control group of 50 from the otology clinic giving a total of 84. MAIN OUTCOME MEASURES Participants completed the Body Dysmorphic Disorder Questionnaire (BDDQ), the sino-nasal outcome test-23 (SNOT-23) and underwent nasal inspiratory peak flow (NIPF). Those found to be at high risk for BDD were referred to a clinical psychologist. RESULTS Of the septorhinoplasty patients, 11 (32%) were high risk for BDD. Following psychological assessment, 7 (63%) patients were felt to be unsuitable for surgery and were offered psychological therapy. SNOT-23 scores were significantly higher in the BDD group indicating a negative impact on quality of life. NIPF readings were not significantly different in the BDD group compared to the control group. CONCLUSIONS The BDDQ is a valid tool for identifying patients at risk of BDD. A close working relationship with clinical psychology has been advantageous to help the selection process of candidates for surgery when there is a high risk of BDD.

Abstract
AIMS Estrogen and progesterone hormone receptor (ER and PR) expression in invasive breast cancer predicts response to hormone disruptive therapy. Pygopus2 (hPYGO2) encodes a chromatin remodelling protein important for breast cancer growth and cell cycle progression. The aims of this study were to determine the mechanism of expression of hPYGO2 in breast cancer and to examine how this expression is affected therapeutically. METHODS hPYGO2 and ER protein expression was examined in a breast tumour microarray by immunohistochemistry. hPYGO2 RNA and protein expression was examined in ER+ and ER- breast cancer cell lines in the presence of selective estrogen hormone receptor modulator drugs and the specificity protein-1 (SP1) inhibitor, betulinic acid (BA). The effects of these drugs on the ability for ER and SP1 to bind the hPYGO2 promoter and affect cell cycle progression were studied using chromatin immunoprecipitation assays. RESULTS hPYGO2 was expressed in seven of eight lines and in nuclei of 98% of 65 breast tumours, including 3 Ductal carcinoma in situ and 62 invasive specimens representing ER-negative (22%) and ER-positive (78%) cases. Treatment with either 4-Hydroxytamoxifen (OHT) or fulvestrant reduced hPYGO2 mRNA 10-fold and protein 5-10-fold within 4 h. Promoter analysis indicated an ER/SP1 binding site at nt -225 to -531 of hPYGO2. SP1 RNA interference and BA reduced hPYGO2 protein and RNA expression by fivefold in both ER- and ER+ cells. Further attenuation was achieved by combining BA and 4-OHT resulting in eightfold reduction in cell growth. CONCLUSIONS Our findings reveal a mechanistic link between hormone signalling and the growth transcriptional programme. The activation of its expression by ERα and/or SP1 suggests hPYGO2 as a theranostic target for hormone therapy responsive and refractory breast cancer.

Abstract
BACKGROUND Patients with chronic rhinosinusitis (CRS) refractory to medical management may elect endoscopic sinus surgery (ESS). Recent data showed that clinical outcomes of patients treated earlier outperformed those of patients treated later in the disease continuum. In this study, CRS-related healthcare utilisation of patients treated early versus late was analysed using the UK-based Clinical Practice Research Database. METHODS Two cohorts ("Early Cohort": ESS within 12 months of first CRS diagnosis, versus "Late Cohort": ≥ 5 years from diagnosis to ESS) were matched for age, gender, asthma, polyposis. Healthcare needs related to CRS were analysed post-operatively for 5 years. RESULTS Patients in the Late cohort used significantly more CRS-related care than patients in the Early cohort visits and 0.54 prescriptions per patient per year. A sub-analysis of patients with and without asthma indicated that patients in the Late cohort without asthma had healthcare needs equivalent to patients in the Early cohort with asthma. CONCLUSION Delayed surgical intervention for CRS is associated with greater post-operative healthcare needs than ESS within 12 months of first CRS diagnosis.

Abstract
BACKGROUND Aprepitant (Emend, Merck Sharp & Dohme Ltd, Haarlem, the Netherlands), a neurokinin-1 receptor antagonist, prevents vomiting in a range of conditions. No data are available on its use in children with cyclical vomiting syndrome (CVS). AIM We investigated the efficacy of aprepitant as prophylactic treatment or acute intervention in CVS children refractory to conventional therapies. METHODS Forty-one children (median age: 8 years) fulfilling NASPGHAN criteria treated acutely (RegA) or prophylactically (RegP) with aprepitant were retrospectively reviewed. Primary outcome was the clinical response (decrease in frequency and intensity of CVS episodes). Secondary outcomes were: number of CVS episodes/year, number of hospital admissions/year, CVS episode duration, number of vomits/h, symptom-free interval length (days), and school attendance percentage. The follow-up period was 18-60 months. RESULTS Sixteen children received RegP and 25 RegA. One child on RegP stopped treatment due to severe migraine. At 12-months on intention-to-treat analysis, 13 children on RegP (81%) achieved either complete (3/16, 19%) or partial (10/16, 62%) clinical response. On RegA, 19 children (76%) had either complete (3/25, 12%) or partial (16/25, 64%) response (P = 0.8 vs. RegP). In both RegP and RegA, there was a significant decrease in CVS episodes/year, hospital admission number/year, CVS episode length, number of vomits/h, as well as an increase in symptom-free interval duration and school attendance percentage. Side effects were reported only in RegP (5/16, 31%) including hiccough (3/16, 19%), asthenia/fatigue (2/16, 12.5%), increased appetite (2/16, 12.5%), mild headache (1/16, 6%) and severe migraine (1/16, 6%). CONCLUSION Aprepitant appears effective for both acute and prophylactic management of paediatric cyclical vomiting syndrome refractory to conventional therapies.

Abstract
BACKGROUND We aim to validate a clinical scoring system of external nasal valve collapse. External nasal valve collapse is a rare and challenging condition. We attempted to simplify the examination of the external valve, the surgical planning and the outcome measure. To validate our external valve score, we first assessed its reliability (inter-rater agreement and test-retest repeatability). We secondly considered the clinical relevance by using our scoring system in patients undergoing septorhinoplasty for external valve collapse. METHODOLOGY For validation, 16 Rhinologists scored patients separately on two occasions. For the clinical relevance, 26 patients with external valve collapse were scored pre- and post-operatively (responsiveness). The external valve score was correlated to peak nasal inspiratory flow. RESULTS The devised scoring system was reliable (substantial agreement between 16 surgeons with reproducibility over time). All patients in our prospective series showed significant improvement in their external valve score. The quality of life measured by the SNOT-22 tool showed significant improvement after surgery. CONCLUSION External nasal valve collapse can be diagnosed and graded using this simple scoring system in the outpatient clinic. This paper reinforces the pivotal role of septorhinoplasty surgery in nasal airway reconstruction and the ongoing need to quantify success.

Abstract
1. The tributyrinases in milk are mainly associated with casein micelles. Dilution or addition of sodium chloride increases the enzyme activity, probably by dissociating the micelle-tributyrinase complexes. 2. Tributyrinase activities of milks activated by dilution and sodium chloride addition were in the range 0.2-1.7muequiv. of acid liberated/ml. of milk/min. from tributyrin emulsion at pH8.5 and 25 degrees . The enzymes have a bivalent-cation requirement for full activity and are rather unstable when separated from casein. 3. Ultracentrifugation of skim milks containing sodium chloride (0.75m) gave preparations low in casein but containing about 70% of the milk tributyrinases. The tributyrinases in such preparations appear to be bound in complexes of molecular weight about 350000. Dilution may result in dissociation to give the free enzymes. 4. Pancreatic lipase also formed complexes with casein micelles, but wheat-germ esterase, xanthine oxidase, milk alkaline phosphatase and other enzymes did not.

Abstract
'Systematic identification of protein interactions for the bacterium Campylobacter jejuni using high-throughput yeast two-hybrid screens detected interactions for 80% of the organism's proteins. Background Data from large-scale protein interaction screens for humans and model eukaryotes have been invaluable for developing systems-level models of biological processes. Despite this value, only a limited amount of interaction data is available for prokaryotes. Here we report the systematic identification of protein interactions for the bacterium Campylobacter jejuni, a food-borne pathogen and a major cause of gastroenteritis worldwide. Results Using high-throughput yeast two-hybrid screens we detected and reproduced 11,687 interactions. The resulting interaction map includes 80% of the predicted C. jejuni NCTC11168 proteins and places a large number of poorly characterized proteins into networks that provide initial clues about their functions. We used the map to identify a number of conserved subnetworks by comparison to protein networks from Escherichia coli and Saccharomyces cerevisiae. We also demonstrate the value of the interactome data for mapping biological pathways by identifying the C. jejuni chemotaxis pathway. Finally, the interaction map also includes a large subnetwork of putative essential genes that may be used to identify potential new antimicrobial drug targets for C. jejuni and related organisms. Conclusion The C. jejuni protein interaction map is one of the most comprehensive yet determined for a free-living organism and nearly doubles the binary interactions available for the prokaryotic kingdom. This high level of coverage facilitates pathway mapping and function prediction for a large number of C. jejuni proteins as well as orthologous proteins from other organisms. The broad coverage also facilitates cross-species comparisons for the identification of evolutionarily conserved subnetworks of protein interactions.

Abstract
DESIGN a cross-sectional study. PARTICIPANTS One hundred and ninety-nine patients with Wegener's granulomatosis belonging to a patient self-help group. MAIN OUTCOME MEASURES Mode of initial presentation; diagnosis timescales and delay; rhinologic involvement; and treatment. RESULTS Sixty-three per cent of patients initially presented with ENT-related symptoms. Ninety-two per cent faced a delay in their diagnosis of more than one month, a pattern which has not improved over the last few decades and which compares unfavourably with North American figures. Rhinologic and otologic symptoms are a common occurrence in up to 85 and 50 per cent of Wegener's granulomatosis patients, respectively, attracting varying degrees of targeted treatment. CONCLUSIONS As sinonasal and other ENT symptoms are so common at the presentation of Wegener's granulomatosis, it is clear that the otolaryngologist has an important role in its diagnosis and treatment. There are long delays in the diagnosis and possible under-treatment of the ENT symptoms of this condition, highlighting the need for greater awareness, particularly in the ENT community.
