Abstract
The seven-item Hospital Anxiety and Depression Scale Depression subscale (HADS-D) and the total score of the 14-item HADS (HADS-T) are both used for major depression screening. Compared to the HADS-D, the HADS-T includes anxiety items and requires more time to complete. We compared the screening accuracy of the HADS-D and HADS-T for major depression detection. We conducted an individual participant data meta-analysis and fit bivariate random effects models to assess diagnostic accuracy among participants with both HADS-D and HADS-T scores. We identified optimal cutoffs, estimated sensitivity and specificity with 95% confidence intervals, and compared screening accuracy across paired cutoffs via two-stage and individual-level models. We used a 0.05 equivalence margin to assess equivalency in sensitivity and specificity. 20,700 participants (2,285 major depression cases) from 98 studies were included. Cutoffs of ≥7 for the HADS-D (sensitivity 0.79 [0.75, 0.83], specificity 0.78 [0.75, 0.80]) and ≥15 for the HADS-T (sensitivity 0.79 [0.76, 0.82], specificity 0.81 [0.78, 0.83]) minimized the distance to the top-left corner of the receiver operating characteristic curve. Across all sets of paired cutoffs evaluated, differences of sensitivity between HADS-T and HADS-D ranged from -0.05 to 0.01 (0.00 at paired optimal cutoffs), and differences of specificity were within 0.03 for all cutoffs (0.02-0.03). The pattern was similar among outpatients, although the HADS-T was slightly (not nonequivalently) more specific among inpatients. The accuracy of HADS-T was equivalent to the HADS-D for detecting major depression. In most settings, the shorter HADS-D would be preferred.

Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
Objective: To examine the survival rates and clinical characteristics of people with newly discovered non-M(3) acute myeloid leukemia (AML) who carry the ASXL1 gene mutation. Methods: From January 2016 to April 2021, the clinical information of patients with newly diagnosed non-M(3) AML at Shandong University's Qilu Hospital was retrospectively examined, and their clinical characteristics and survival were compared and analyzed. Gene mutation was detected by next-generation sequencing. Results: ① The study included 256 AML patients who were initially diagnosed and had complete data, including 47 cases of ASXL1 gene mutation-positive (ASXL1(+)) patients and 209 cases of ASXL1 gene mutation-negative (ASXL1(-)) patients. All patients were divided into three groups: elderly (≥60 years old, n=92) , middle-aged (45-59 years old, n=92) , and young (≤44 years old, n=72) . ②WBC, and age were higher in patients with ASXL1 mutations compared to ASXL1(-) patients, while complete response after the first round of treatment (CR(1)) was lower (P<0.05) . In the elderly group, WBC and the proportion of aberrant cells in nuclear cells in ASXL1(+) patients were higher than those in ASXL1(-) patients (P<0.05) . In the young group, the WBC of ASXL1(+) patients was higher than that of ASXL1(-) patients (z=-2.314, P=0.021) . ③IDH2 mutation and ASXL1 mutation was related (P=0.018, r=0.34) . In ASXL1(+) patients, the proportion of peripheral blasts in the high VAF group (VAF>40% ) was higher than that in the low VAF group (VAF<20% ) , and the proportion of aberrant nuclear cells was higher in the duplication and replacement mutation patients than in the deletion mutation patients (P<0.05) . ④The overall survival (OS) and progression-free survival (PFS) of ASXL1(+) patients were shorter than those of ASXL1(-) patients (median, 10 months vs 20 months, 10 months vs 17 months; P<0.05) . The proportion number of aberrant cells in nuclear cells (≥20% ) , complex karyotypes, and TET2 mutation were all independent risk variables that had an impact on the prognosis of ASXL1(+) patients, according to multivariate analysis (P<0.05) . Conclusion: ASXL1-mutated non-M(3) AML patients have higher WBC in peripheral blood, a higher proportion of aberrant cells in nuclear cells, lower CR(1) rate, and shorter OS and PFS. Additionally, a poor prognosis is linked to higher VAF, duplication, and substitution mutations in the ASXL1 gene, as well as the high proportion of aberrant cells in nuclear cells, complex karyotype, and TET2 mutation.

Abstract
OBJECTIVE This study aimed to determine the prognostic role of baseline maximum standardized uptake value (SUVmax) obtained by pretreatment PET/CT and the change in SUVmax (ΔSUVmax [%]) in patients with axillary lymph node-positive breast cancer receiving neoadjuvant chemotherapy (NAC). METHODS One hundred and eighty patients with baseline SUVmax and 121 patients with SUVmax measurement after treatment were evaluated in the study. The baseline SUVmax value of the breast (SUVmaxBI) and axilla (SUVmaxAI) and the change in the SUVmax of the breast (ΔSUVmaxB) and axilla (ΔSUVmaxA) were measured. The optimal cut-off value of SUVmax and ΔSUVmax were determined by ROC curve analysis. Disease-free survival (DFS) and overall survival (OS) were calculated using Kaplan-Meier curves. RESULTS ΔSUVmaxB, pCRB, pCRA, and pCR parameters were found to be associated with relapse (p < 0.001, p = 0.033, p = 0.016, and p = 0.013, respectively). ΔSUVmaxB and SUVmaxAI were associated with mortality (p = 0.001 and p = 0.006, respectively). Multiple Cox regression analyses revealed that ΔSUVmaxB value was an independent prognostic factor for relapse and mortality (p = 0.013 and p = 0.010, respectively). CONCLUSION The results showed that ΔSUVmaxB was an independent prognostic factor for relapse and mortality in patients with axillary lymph node-positive breast cancer who received NAC.

Abstract
AIM OF THE STUDY The purpose of the study was to determine the aeroallergen sensitisation patterns of children aged 5 years and younger with asthma (AS) and/or allergic rhinitis (AR) in Istanbul, Turkey. METHODS This cross-sectional observational study was conducted between January and December 2018 in the outpatient clinic of a hospital department of pediatric allergy. Patients, who had regular outpatient controls, full clinical and laboratory records, positive skin prick test results, and were willing to participate in the study, were included. RESULTS In total, 148 children aged 5 years or younger who had positive skin prick test results were included in the study. The male/female ratio and the mean age at onset of symptoms were 87/61 and 2.13±1.33 (0.4-4.5) years, respectively. Of the 148 patients, 63 (42.6%) had AS, 11 (7.4%) AR, and 74 (50.0%) had both AS and AR. The age of the patients, age at symptom onset, male/female ratio, number of allergen sensitivities, total IgE levels, total eosinophil levels, and skin prick test results for aeroallergens did not differ between the patients with AS, AR, and AS+AR. House dust mite (HDM) was the most common aeroallergen in patients, while the cockroach was the least common aeroallergen. The severity of asthma and control levels were not found to be associated with aeroallergen sensitisation in children. CONCLUSION One out of every four atopic children aged 5 years or younger is sensitised to aeroallergens. The most common sensitisation is to house dust mites. Weed aeroallergen may be related to severity of asthma in children aged 5 years or younger in Istanbul. We speculate that HDM and weed allergens could be used in the diagnostic or treatment strategies for the management of asthmatic children aged 5 years or younger.

Abstract
Objective One-third of patients newly diagnosed with a kidney tumor have metachoronous disease, 25-50% have synchronous metastasis, and approximately 30-40% of patients have metastasis at the time of diagnosis. Metastasis mostly occurs in the lungs, regional lymph nodes, bones, and liver. The present study was aimed to determine the effect on mortality the values of standard uptake value (SUV)max measured with positron emission tomography (PET) in metastases of kidney tumors. Material and Methods A retrospective review was conducted of the files of 77 patients newly diagnosed with kidney tumor and disease staging determined with PET in the Nuclear medicine Department of Saglik Bilimleri University Diyarbakir Gazi Yasargil Training and Research Hospital between August 2007 and April 2012. The gender, age, histological types, metastases, SUVmax values, and dates of death of the patients were recorded in the SPSS software. Results It was observed that higher SUVmax values indicated a shorter survival time (r = .303) (P = 0.022). Patients with metastasis lived for a shorter period (P < 0.001), particularly those with liver metastasis (r = .515) (P = 0.049). Metastases were most frequently seen in lymph nodes (42.1%); the SUVmax values of lung metastases were higher (P = 0.025) and papillary carcinomas showed higher SUVmax uptake (P = 0.015). Conclusions In the present study, it was concluded that the higher the SUVmax value the shorter the survival time. The survival time of patients with metastasis was shorter, and this could be estimated through the measured SUVmax values.

Abstract
Introduction This study aimed to evaluate the clinical efficacy of intravenous metoclopramide for the relief of pain and nausea among the emergency department patients with renal colic. Methods Patients were randomised into three groups: tenoxicam (20 mg); tenoxicam (10 mg) plus metoclopramide (10 mg); and metoclopramide (10 mg). Changes in pain and nausea were examined at the 10th, 20th and 30th minute after treatment. The development of side effects would be recorded. After the 30th minute, the need for additional pain and nausea relief was evaluated. Results Totally 80 patients were enrolled in each group. There was significant mean pain score difference as measured by visual analog scale (VAS) from 0 minute to 10th, 20th and 30th minute post-treatment for all treatment groups (p<0.001). There was no significant difference in mean VAS decrease from 0 minute to the 30th minute: tenoxicam group: 36 mm [95% confidence interval (CI) 28-43 mm] vs. tenoxicam plus metoclopramide: 45 mm (95% CI 38-52 mm) vs. metoclopramide group: 37 mm (95% CI 30-45 mm) (p=0.163). Similarly, no significant differences in mean nausea scores between the three groups were demonstrated at the 10th, 20th and 30th minute after treatment (p=0.236, 0.330 and 0.652 respectively). After the 30th minute, 43 (53%) patients needed additional pain relieving agent in the tenoxicam group compared to 27 (33%) patients in the tenoxicam-metoclopramide group and 33 (41%) patients in the metoclopramide group (p=0.030). No significant adverse drug reaction events were encountered. Conclusion Metoclopramide is as effective as tenoxicam to treat pain and nausea for patients with renal colic in the emergency department. (Hong Kong j.emerg.med.2015;22:93-99)

Abstract
AIMS The purpose of the study was to examine the association between visceral adiposity form of non-alcoholic fatty liver and coronary artery disease severity and also to investigate the relationship between the epicardial adipose tissue thickness and non-alcoholic fatty liver disease with clinical and anthropometric measurements. MATERIALS AND METHODS This study included 105 patients (mean age of patients were 57 ± 11, 82 of them male) who were hospitalized for coronary angiography because of chest pain. Nonalcoholic fatty liver disease was investigated by using ultrasonography. Thickness of the epicardial adipose tissue was measured by transthorasic echocardiography to right ventricular free wall adjacent to the parasternal long and short axis images. Gensini score was used for the severity of coronary artery disease. RESULTS In patients with non-alcoholic fatty liver disease, right ventricular free wall epicardial adipose tissue thickness average of parasternal long and short axis were thicker than those who do not have non alcholic fatty liver disease (0,90 ± 0,19 cm; 0.58 ± 0.18 cm, p<0.001). Also, in patients with severe coronary artery disease, right ventricular free wall parasternal long and short axis average thickness of epicardial fat tissue was thicker than those of patients without severe coronary stenosis (0.86 ± 0.21 cm; 0,66 ± 0.26 cm, p=0.001). For predictability of coronary artery disease, Receiver Operating Characteristic analysis of the area under the curve was found to be 0.60 (50.2 to 74.7, 95% Confidence Limits). CONCLUSIONS Not only the fatty tissue which surrounds the heart effects the coronary arteries but also other visceral organs adiposity effects the coronary arteries atherosclerotic process.

Abstract
AIM The study is aimed to determine the beneficial effects of methyl palmitate (MP) which has antioxidant and anti-inflammatory effects demonstrated on murine model of acute lung injury induced by lipopolysaccharide (LPS). MATERIALS AND METHODS Forty male BALB/C mice were randomly allocated into four groups (n=10, each): control group, methyl palmitate group (300 mg/kg), LPS group, and methyl palmitate -treated groups. Methyl palmitate or vehicle was given with an intraperitoneal administration 1 h before an intratracheal instillation of LPS (5 mg/kg). The severity of pulmonary injury was evaluated 6 h after LPS challenge. All experimental procedures complied with the requirements of the Animal Care and Ethics Committee of the Adnan Menderes University. RESULTS Methyl palmitate pretreatment significantly attenuated LPS-induced pulmonary histopathologic changes, alveolar hemorrhage, and neutrophil infiltration. Methyl palmitate pretreatment also reduced the concentrations of malondialdehyde in lung tissues. CONCLUSIONS This study indicates that methyl palmitate may have a protective effect against LPS-induced acute lung injury, and the potential mechanism of this action may involve the inhibition of NF-κB. activation.

Abstract
PURPOSE To predict the invasiveness of urothelial bladder carcinoma using a logistic regression model on preoperative peripheral blood samples. PATIENTS AND METHODS Hospital data of patients operated for urothelial carcinoma were reviewed retrospectively. Preoperative blood samples were collected before the first cystoscopic examination. Any kind of infection or inflammation was an exclusion criterion. Patients were grouped as having a non-muscle-invasive or muscle-invasive urothelial carcinoma. The mean age was 69 years and was determined as the cut-off value. According to receiver operating characteristic curves, threshold points were determined for lymphocytes, neutrophil count, neutrophil-to-lymphocyte ratio (NLR), thrombocytes and mean platelet volume. Demographic specialties, parameters obtained from blood samples, tumor size and multiplicity were evaluated and significant parameters were put into a logistic regression model. RESULTS The study group consisted of 80 non-muscle-invasive and 102 muscle-invasive patients. Age (≤69 vs. >69), female gender, NLR (2.57), mean platelet volume (7.9/fl) and platelet count (400,000/µl) were significant parameters and put in a model. Using odds ratios, the probability of tumor invasiveness was calculated by a formula. CONCLUSION Age, female gender, NLR and platelet count were found to be the predictors of invasiveness of urothelial carcinoma.

Abstract
PURPOSE We validated the PADUA classification and assessed the R.E.N.A.L. nephrometry score to predict perioperative complications of partial nephrectomy. In addition, we assessed their interobserver variability, and the ability to predict the use of ischemia and ischemia time. MATERIALS AND METHODS Data from consecutive cases of partial nephrectomy with or without ischemia from 3 centers were retrospectively collected. Associations between preoperative variables and complications were evaluated in univariate and multivariate analyses. Reproducibility was assessed by determining Fleiss' generalized kappa and intraclass correlation coefficients in a subcohort scored by 3 physicians with different degrees of urological expertise. RESULTS A total of 134 partial nephrectomies were included in the study and 31 cases (23%) presented with complications. On univariate analyses complications were associated with age (p = 0.02), tumor size on computerized tomography (p = 0.01), pT stage (p = 0.001), and PADUA (p = 0.001) and R.E.N.A.L. scores (p = 0.02). In 3 multivariate models PADUA score 10 or greater (OR 3.98, p = 0.01), R.E.N.A.L. score 9 or greater (OR 4.21, p = 0.02), tumor size in cm (OR 1.35, p = 0.02) and age (OR 1.04, p = 0.04) were independent predictors of complications. The R.E.N.A.L. nephrometry score predicted the use of ischemia (p = 0.03) and both scores predicted ischemia time (both p <0.001). Kappa was 0.37 to 0.80 for PADUA components and 0.23 to 0.73 for R.E.N.A.L. components. The intraclass correlation coefficient was 0.73 for PADUA and 0.70 for R.E.N.A.L. score. CONCLUSIONS The highest categories of PADUA and R.E.N.A.L. scores as well as clinical tumor size predict the risk of perioperative complications of partial nephrectomy. Both scores can indicate ischemia time. Their reproducibility is substantial but the implementation of these systems in clinical practice needs further refinement.

Abstract
OBJECTIVES Elevation of serum total homocysteine (tHcy) is considered to contribute to endothelial cell dysfunction, which is considered to be the initial event in posttransplant vascular disease. We sought to investigate whether an association existed between serum tHcy levels and vascular endothelial function during cyclosporine (CsA) treatment. MATERIALS AND METHODS Endothelium-dependent and -independent relaxation responses (to acetylcholine [ACh] and sodium nitroprusside [SNP]) were determined on thoracic aortae from CsA-treated rats (5 mg kg/d, subcutaneously, for 14 days). A correlation analysis was performed between ACh responses and tHcy levels. RESULTS CsA decreased the responses to ACh and the pD(2) values of the concentration-response curves compared with controls (P < .05). Responses to SNP and serum tHcy levels were unchanged among the groups. tHcy negatively correlated with the ACh pD(2) values among control (r = -0.69; P < .05) and vehicle (r = -0.73; P < .05) groups, indicating that the increase in tHcy was associated with decreased sensitivity to ACh. In CsA-treated rats, no association was observed between these parameters. Also, no correlation was noted between CsA concentrations and tHcy levels. CONCLUSION These data suggested a possible link between serum tHcy and decreased vascular sensitivity to endothelium-dependent vasorelaxation in control aortae, but CsA-induced vascular endothelial dysfunction was not associated with an effect of the drug on homocysteine metabolism.

Abstract
In July 2005, small (2 to 5 mm), elongated, dark brown spots on the stems of Cicer pinnatifidum Jaub. & Spach. were observed on plants grown in the rocky hills of the Kahramanmaras Province. To understand this phenomenon, field trips to Kahramanmaras, Adiyaman, and Sanliurfa provinces were conducted in the summer of 2006. C. pinnatifidum plants exhibiting symptoms similar to Ascochyta rabiei (Pass.) Lab. were collected during May and June. The plants had flowers and pods with seeds at the time of collection. Ascochyta blight symptoms on stems were not extensive. None of the plants had leaf symptoms, but one plant had lesions on its pods. Twelve plants exhibiting Ascochyta blight symptoms were taken to the laboratory, and necrotic parts were used for isolation of the fungi on potato dextrose agar (PDA). After 3 to 5 days of culturing on PDA, characteristic beige-to-dark brown colony development of A. rabiei from explants was observed and five isolates from different locations were recovered. The fungal colony growth was slow and limited conidia formed on PDA. The isolates were also cultured on chickpea meal agar (CMA) and Czapek Dox Agar (CDA) media. Abundant conidia formation occurred only on CMA, 10 to 12 days after culturing. Conidia were one-celled similar to that of A. rabiei of chickpea and single-spore isolations were done. C. pinnatifidum and chickpea cv. Gokce (C. arietinum L.) were inoculated with spore suspensions of 5 × 105 spores per ml (2). Ten- to twelve-day-old seedlings were used for inoculation in the experiments. Brown-black lesions at the crown region on C. pinnatifidum seedlings were observed 9 to 10 days after inoculation, and characteristic Ascochyta blight symptoms on stems developed on chickpea cv. Gokce. The fungus was reisolated from the infected seedlings. For molecular characterization, mating type of the isolates was determined by PCR using A. rabiei specific Tail1, Com1, and Sp21 primers (1). A single band of Mat 1.2 specific 500- bp product was amplified by PCR from five of the A. rabiei isolates of C. pinnatifidum. This confirmed that the isolates from C. pinnatifidum are A. rabiei.

Abstract
Replacement lipomatosis of the kidney is the result of severe atrophy of the renal parenchyma often caused by chronic calculus disease with secondary marked benign proliferation of fibrofatty tissue replacing atrophied renal parenchyma. Different radiological modalities have been used to illustrate this entity, with magnetic resonance imaging, ultrasound, intravenous pyelogram, and computed tomography (CT) used most frequently. We report multidedector CT (MDCT) findings of replacement lipomatosis in a 50-year-old woman. We think that it accurately provides a complete one-step diagnostic workup and appropriate pre-surgical planning for patients for whom there is a suspicion of replacement lipomatosis.

Abstract
OBJECTIVE To assess the effects of smoking on total sperm count, progressive sperm motility and sperm morphology among couples attending an infertility clinic. METHODS A total of 223 sperm samples (126 smokers and 97 nonsmokers) from men attending an infertility clinic for routine infertility workup were compared on the basis of standard semen analysis. RESULTS Cigarette smoking is negatively correlated with progressive motile sperm count (r = -0.1464, p = 0.042), but not with sperm concentration (p = 0.961), total motile sperm count (p = 0.890) and sperm morphology (p = 0.838). Furthermore, packages/ year (cumulative dose of cigarettes) did not correlate with any of the sperm parameters including sperm density (p = 0.976), total (p = 0.559) and progressive (p = 0.406) motile sperm count and sperm morphology (p = 0.449). CONCLUSIONS Although the effect of smoking on male infertility remains inconclusive, smoking had an adverse effect on the progressive sperm motility, irrespective of total amount of cigarettes smoked per day.

Abstract
PURPOSE To assess the role of F-18 FDG imaging with a dual head coincidence mode gamma camera (Co-PET) in the detection of renal cell carcinoma (RCC) in patients with renal masses. MATERIAL AND METHODS An F-18 FDG Co-PET study was performed in 19 patients (7 F, 12 M; mean age 58.15 +/- 2.5 years, age range 45-79 years) with suspected primary renal tumors based on conventional imaging techniques, including computed tomography (CT) and ultrasonography (US) before nephrectomy or surgical resection of the mass. RESULTS Histologically documented RCC was present in 15 patients. Of the 19 patients with suspected primary renal tumors, F-18 FDG Co-PET was true-positive in 13, false-negative in 2, true-negative in 3, and false-positive in I patient. Two angiomyolipomas and one renal mass due to infarction and hemorrhage showed a true-negative Co-PET result. The patient with false-positive FDG Co-PET study was diagnosed as xantogranulomatous pyelonephritis. Overall sensitivity, specificity, and accuracy of FDG Co-PET for RCC were 86% (13/15), 75% (3/4), and 84% (16/19), respectively. Positive predictive value for RCC was 92% and negative predictive value 60%. CONCLUSION These findings suggest that F-18 FDG Co-PET may have a role in the diagnostic evaluation of patients with RCC and primary staging of disease. Positive F-18 FDG study may be predictive of the presence of RCC. However, a negative study does not exclude the RCC.

Abstract
The current study was designed to evaluate the endotoxin-induced alterations of the mechanisms involved in Ca(2+)handling within the rat thoracic aorta and further to examine whether in vitro inhibition of inducible nitric oxide synthase (iNOS) by aminoguanidine would account for this effect or not. Endothelium denuded aortic rings from rats injected with lipopolysaccharide (LPS) (5 mg kg(-1), i.p. 18 h prior to functional studies) or saline were mounted in isolated organ baths. Various experimental conditions were studied on paired rings of the same animal which were incubated in the presence or absence of aminoguanidine (100 microM). Phenylephrine contractility in Ca(2+)-containing buffer or in Ca(2+)-free buffer, contractions induced by K(+)depolarization and CaCl(2)in depolarized muscle and by caffeine exposure were significantly decreased in LPS-treated rings and were reversed by aminoguanidine exposure. Aminoguanidine also improved the contractions recorded while switching the Ca(2+)-free buffer to Ca(2+)-containing buffer. We conclude that endotoxin induces a generalized contractile defect in vascular smooth muscle including impairment in the influx of extracellular Ca(2+)and release of Ca(2+)from intracellular stores. An increase in iNOS activation leading to excessive nitric oxide synthesis, possibly non-endothelial in origin, may account for this defect.

Abstract
<b>Purpose:</b> The aim of this study was to evaluate the efficacy of octreotide in modulating the progression of intimal hyperplasia in autogenous vein bypass grafts in a canine model. The effect of the drug on the progression of intimal hyperplasia was measured with the Gilman parameter, a measure used extensively as a wound-healing descriptor. <b>Methods:</b> 12 mongrel dogs were randomly and equally divided into two groups. The first group (octreotide group) was administered octreotide 20 µg/kg/day. The control group (group II) received saline solution by subcutaneous injection. Each dog had 8- to 10-cm segments of autogenous jugular vein bypassed to the femoral arteries. Quantitative data on luminel narrowing over time from intimal hyperplasia were compared from calculated Gilman parameters after image analysis of retrieved, histologically processed graft sections. Each vein graft was analyzed by computerized morphometric analysis. <b>Results:</b> The mean Gilman parameter for distal graft segments was 0.47 ± 0.17 mm in the control group and 0.25 ± 0.07 mm in the octreotide group 6 weeks after operation (p < 0.05). Distal graft segments between the control and octreotide groups were statistically significant. In proximal, medial and distal graft segments, the mean Gilman parameters were 0.51 ± 0.16 mm in the control group and 0.37 ± 0.18 mm in the octreotide group, the difference being statistically significant (p < 0.01). <b>Conclusion:</b> Octreotide significantly inhibits myointimal thickening, and these data support the efficacy of octreotide in reducing intimal hyperplasia in arterialized vein grafts during the short postoperative period. Further investigations are required to as certain whether this beneficial effect of octretide persists in the long term.

Abstract
To better understand the genetic requirements for R gene-dependent defense activation in Arabidopsis, we tested the effect of several defense response mutants on resistance specified by eight RPP genes (for resistance to Peronospora parasitica) expressed in the Col-0 background. In most cases, resistance was not suppressed by a mutation in the SAR regulatory gene NPR1 or by expression of the NahG transgene. Thus, salicylic acid accumulation and NPR1 function are not necessary for resistance mediated by these RPP genes. In addition, resistance conferred by two of these genes, RPP7 and RPP8, was not significantly suppressed by mutations in either EDS1 or NDR1. RPP7 resistance was also not compromised by mutations in EIN2, JAR1 or COI1 which affect ethylene or jasmonic acid signaling. Double mutants were therefore tested. RPP7 and RPP8 were weakly suppressed in an eds1-2/ndr1-1 background, suggesting that these RPP genes operate additively through EDS1, NDR1 and as-yet-undefined signaling components. RPP7 was not compromised in coi1/npr1 or coi1/NahG backgrounds. These observations suggest that RPP7 initiates resistance through a novel signaling pathway that functions independently of salicylic acid accumulation or jasmonic acid response components.

Abstract
A 20-year-old male, with no history of chronic liver disease, presented with fulminant hepatic failure. The cause was not established until post mortem when it was found that he had a primary hepatocellular carcinoma in a non-cirrhotic liver. To our knowledge, this is the third report of hepatocellular carcinoma presenting in this manner. Although rare, primary malignancies of the liver should be considered in the differential diagnosis of fulminant hepatic failure, especially when other more common causes are excluded.

Abstract
OBJECTIVES to evaluate the efficacy of single-dose pre-insertion gamma radiation of vein grafts in the prevention of intimal hyperplasia. METHODS femoral artery interposition grafts with internal jugular vein were inserted in 12 mongrel dogs. The animals were randomly divided into two groups. Immediately before graft replacement, jugular veins were treated with a single dose of cobalt-60 radiation at 14 Gy or received no radiation (control group). Six weeks after graft insertion, the vein grafts were pressure-perfusion fixed and harvested for the histomorphometric analysis. Quantitative data on anastomotic stenosis were calculated from Gilman parameters after cross-sectional image analysis. RESULTS vein grafts treated with radiation demonstrated significantly decreased neointima formation compared with grafts in the control group. The mean Gilman parameter for the control group was 1.09 S.E.M. 0.34 mm and for the radiotherapy group was 0.65 S.E. M. 0.23 mm (p<0.05). All vein grafts in the radiotherapy group had a decreased amount of intimal and cellular infiltration. CONCLUSION single-dose external pre-insertion gamma radiation of vein grafts reduced the amount of intimal hyperplasia in this animal model.

Abstract
We investigated the effects of orally supplemented L-arginine, the substrate of nitric oxide (NO) and N(omega)-nitro-L-arginine methyl ester (L-NAME), a nitric oxide-synthase inhibitor in gentamicin-induced renal failure. Rats were given gentamicin (100 mg/kg/day s.c.), gentamicin and L-arginine (2 g/l, drinking water), gentamicin and L-NAME (100 mg/l, drinking water) or gentamicin plus L-arginine and L-NAME. After 8 days, the gentamicin group developed marked renal failure, characterized by a significantly decreased creatinine clearance and increased blood creatinine, fractional excretion of sodium, fractional excretion of lithium, urine gamma glutamyl transferase, systolic blood pressure and daily urine volume when compared to controls. Renal histological analysis confirmed tubular necrosis. L-arginine administration caused normalization of these parameters, whereas L-NAME led to aggravation of the failure. Concomitant administration of L-NAME and L-arginine to gentamicin-treated rats caused no significant changes when compared to the rats receiving gentamicin alone. We conclude that L-arginine supplementation has beneficial effects in gentamicin-induced renal failure in rats and that these effects are reversed by the NO-synthase inhibitor, L-NAME.

An 18-year-old female patient was hospitalized with headache and disturbance of consciousness. Magnetic resonance imaging (MRI) revealed a tumor in the left parieto-occipital lobe. The tumor was totally removed, and postoperative radiation therapy was administered locally at 50 Gy. Ten months later, she experienced sudden onset of unconsciousness and headache. Computed tomography (CT) and MRI demonstrated multiple mass lesions in the whole brain. Following the systemic chemotherapy, removal of the largest tumor was performed. Histological examination proved all excised tumors to be oligodendroglioma without evidence of malignant change.

Abstract
The safety and histopathologic effects of polytetrafluoroethylene (Gore-Tex) grafts in reconstruction of the urinary bladder were examined. Following partial excision of the bladder Gore-Tex was placed, and the rats were sacrificed at days 7, 14 and 30. Gore-Tex did not cause urine infection, and there was no peritonitis or sepsis in any of the rats. Inflammation around the Gore-Tex diminished after four weeks. Some mononuclear cells and exudate were observed on the inner surface of the Gore-Tex. There was no inflammation or fibrosis in the mucosa and muscular layers of the remaining bladder. In this study the Gore-Tex graft was found to be an infection resistant, urine impermeable material, with no adverse effects on the urinary bladder. Gore-Tex is suggested as a safe material for the reconstruction of the urinary bladder.

Abstract
In 1910, Chiliaditi described hepatodiaphragmatic interposition of the colon (Chiliaditi's syndrome). The condition is easily recognised on an antero-posterial chest radiograph. The interposed segment of bowel is usually the hepatic flexure of the colon. The degree of interposition varies from simple wedging to complete occupation of the right subdiaphragmatic space. The management is usually conservative and surgical intervention is rarely indicated. We present a patient with hepatodiaphragmatic interposition of the colon, associated with megacolon, requiring subtotal colectomy and ileosigmoid anastomosis for severe chronic constipation.

Abstract
The tanycytic ependymoma is an extremely rare, primitive neuroectodermal tumor, arising from the ependymoglial cells or tanycytes. Such cells are generally seen in the primitive nervous system instead of the mature ependymal cells. The tanycytic ependymoma described in this report was found in a 42-year-old man. Histological analysis strongly suggested that this tumor originated from a primitive progenitor cell, the ependymoglia or the tanycyte in the lateral ventricle.

Abstract
In this study, the effects of intraperitoneal 5-fluorouracil (5-FU), cisplatinum (Cis), adriamycin (Adr), and methotrexate (MTX) administration on rat intestinal anastomosis were compared. Cis and MTX led to significant weight loss in the first 5 days compared with the control group. Within 14 days all rats except the MTX group nearly reached their preoperative weight. No remarkable weight loss or systemic toxicity was observed among the 5-FU and Adr groups. The anastomosis bursting pressure (ABP) at 1 week was significantly lower than that of the control group (P < 0.01 and P < 0.005, respectively). On day 14 the anastomosis bursting pressure in the Cis group was similar to that of the control group but was significantly lower in the MTX group (P < 0.002). Histopathologically, MTX avoided the development of a mucosal layer at the anastomosis site and led to ulcer formation in some of the rats. The ABPs at 7 and 14 days were similar to those in the control group. Neither of the agents had any significant mechanical or histopathologic adverse effects on anastomosis. According to the results of our study, MTX impaired the healing of the anastomosis, and we thus conclude that the intraperitoneal administration of this agent is not safe. On the other hand, Cis showed a detrimental effect on the anastomosis, particularly in the early phase, but this effect disappeared in the late phase. Cis thus should not be administered in the early postoperative phase. As a result, 5-FU and Adr were found to be the safest agents as they did not delay wound healing and did not reduce the anastomotic strength.

Abstract
Fifteen isolates of the biotrophic oomycete Peronospora parasitica (downy mildew) were obtained from a population of Arabidopsis thaliana plants that established naturally in a garden the previous year. They exhibited phenotypic variation in a set of 12 Arabidopsis accessions that suggested that the parasite population consisted of at least six pathotypes. One isolate, Maks9, elicited an interaction phenotype of flecking necrosis and no sporulation (FN) in the Arabidopsis accession Nd-1, and more extensive pitting necrosis with no sporulation (PN) in the accession Ws-2. RPP13 was designated as the locus for a single dominant resistance gene associated with the resistance in Nd-1 and mapped to an interval of approximately 60 kb on a bacterial artificial chromosome (BAC) contig on the lower arm of chromosome 3. This locus is approximately 6 cM telomeric to RPP1, which was previously described as the locus for the PN interaction with five Peronospora isolates, including resistance to Maks9 in Ws-2. New Peronospora isolates were obtained from four other geographically distinct populations of P. parasitica. Four isolates were characterized that elicited an FN phenotype in Nd-1 and mapped resistance to the RPP13 locus. This suggests that the RPP13 locus contains either a single gene capable of multiple isolate recognition or a group of tightly linked genes. Further analysis suggests that the RPP11 gene in the accession Rld-0 may be allelic to RPP13 but results in a different recognition capability.

Abstract
BACKGROUND AND OBJECTIVE A variety of biologic or synthetic materials have been used in brow suspension ptosis surgery. We describe extrusion and granuloma formation in 5 cases of congenital ptosis operated with Mersilene mesh sling. PATIENTS AND METHODS Case reports with review of literature. RESULTS Two cases of extrusion and 3 cases of granuloma formation were encountered in 79 eye lids of 52 (6.3%) patients performed for the treatment of congenital ptosis. Mersilene mesh fibers in the cut surface and a foreign body reaction were found by microscopic evaluation of tissue harvested at the time of surgical removal of the sling. CONCLUSION Despite the operative precautions, the probability of extrusion and granuloma formation should be in mind in cases of congenital ptosis operated with Mersilene mesh sling, a synthetic material.

Abstract
The metallothionein gene, LSC54, shows increased expression during leaf senescence in Brassica napus and Arabidopsis thaliana. A number of abiotic and biotic stresses have been shown to induce senescence-like symptoms in plants and, to investigate this further, the promoter of the LSC54 gene was cloned and fused to the GUS gene and transformed into Arabidopsis. The promoter was highly induced during leaf senescence and also in response to wounding; histochemical analysis indicated that this induction was localised to a few cells close to the wound site. The transgenic Arabidopsis tissue was infected with compatible and incompatible isolates of both the fungal biotroph, Peronospora parasitica and the bacterial necrotroph, Pseudomonas syringae. Incompatible isolates induced rapid cell death (the hypersensitive response) at the site of infection and, with both pathogens, early, localised expression of the GUS gene was observed. In contrast, relatively slow induction of the GUS gene was seen in the compatible interaction and this was correlated with the appearance of senescence-like symptoms in the biotrophic interaction and cell death by necrosis that occurred in response to the necrotrophic pathogen. These results suggest that there are common steps in the signalling pathways that lead to cell death in the hypersensitive response, pathogen induced necrosis and senescence.

Abstract
1. Vascular contractile and relaxant responses were evaluated in isolated aortic rings of adjuvant-induced arthritic rats in comparison with control rats, and the effect of an antioxidant treatment on the development of the arthritis was investigated by vitamin E administration (100 mg/kg/day, i.m., for 26 days). 2. Arthritis was induced by an intradermal injection of Freund's complete adjuvant into rat paw. Vascular responses, arthritic lesions and serum copper levels were evaluated after 26 days from adjuvant inoculation. 3. Serum copper levels were significantly lower in arthritic rats than in the control. 4. The contractile response of aortic rings to phenylephrine (PE), but not to KCl, was increased in preparations from arthritic rats, which could be explained by an enhancement of intracellular calcium contents. 5. Acetylcholine (Ach)-mediated endothelium-dependent and sodium nitroprusside (SNP)-mediated endothelium-independent relaxations were not changed significantly in vascular preparations from arthritic rats. 6. In arthritic rats, vitamin E treatment improved arthritic lesions with an increase in copper levels. Despite this ameliorating effect, vitamin E treatment caused an increase in contractile response to PE and a decrease in the relaxant response to Ach and SNP in arthritic rats. 7. These data show that vitamin E provides ameliorating effects in improving systemic signs of experimental arthritis, but it fails to restore abnormalities in vascular function, indicating that adjuvant-induced alterations in vascular function may include mechanisms other than oxygen-free radical formation.

Abstract
The soilborne, vascular pathogen Ralstonia solanacearum, the causative agent of bacterial wilt, was shown to infect a range of Arabidopsis thaliana accessions. The pathogen was capable of infecting the Col-5 accession in an hrp-dependent manner, following root inoculation. Elevated bacterial population levels were found in leaves of Col-5, 4 to 5 days after root inoculation by the GMI1000 strain. Bacteria were found predominantly in the xylem vessels and spread systematically throughout the plant. The Nd-1 accession of A. thaliana was resistant to the GMI1000 strain of R. solanacearum. Bacterial concentrations detected in leaves of Nd-1, inoculated with an hrp+ strain of R. solanacearum, were only slightly higher than those detected in the susceptible accession, Col-5, following inoculation with a strain whose hrp gene cluster was deleted. Leaf inoculation of the GMI1000 strain on the resistant accession Nd-1 induced the formation of lesions in the older leaves of the rosette whereas the same strain of R. solanacearum provoked complete wilting of Col-5. Resistance to strain GMI1000 of R. solanacearum segregated as a simply inherited recessive trait in a genetic cross between Col-5 and Nd-1. F9 recombinant inbred lines generated between these two accessions were used to map a locus, RRS1, that was the major determinant of resistance between restriction fragment length polymorphism markers mi83 and mi61 on chromosome V. This region of the A. thaliana genome is known to contain many other pathogen recognition capabilities.

Abstract
Leukotrienes are one of the biological mediators that play a role in endotoxic shock. In this study, we investigated the effects of a leukotriene biosynthesis inhibitor, MK-886, in a rabbit model of endotoxic shock. Lipopolysaccharide (Escherichia coli serotype 055:B5) infusion (1 mg kg(-1) h(-1)) to rabbits caused a biphasic decline in arterial blood pressure and decreased the vasoresponsiveness to phenylephrine, potassium chloride, sodium nitroprusside and acetylcholine in abdominal aortic rings. Oral administration of MK-886 (3-(1-(4-chlorobenzyl)-3-t-butyl-thio-5-isopropylindol-2-yl(-2,2-+ ++dimethylpropanoic acid) (5 mg/kg) 3 h prior to lipopolysaccharide infusion significantly inhibited the decline in arterial blood pressure and enhanced the responsiveness to phenylephrine and acetylcholine, whereas the changes in sodium nitroprusside and potassium chloride responses were not significant. However, the pD2 (-log EC50) values for sodium nitroprusside in this group were higher than those of the group that received lipopolysaccharide alone. Neither the administration of the vehicle alone to endotoxemic rabbits, nor MK-886 administration to control animals, caused significant changes. These data suggest that MK-886 attenuates the hypotension and partially reverses the impaired vascular responsiveness observed in endotoxic shock.

Abstract
Antrochoanal polyps are rare lesions. Several surgical techniques have been reported to provide complete cure of the disease. However, inadequate treatment may result in a high rate of recurrences. The aetiological as well as predisposing factors are not well understood. We present a literature review and discuss the clinical, pathological and histological features of 16 patients with antrochoanal polyps, who have been surgically treated by either an endoscopical or conventional approach. It has been found that allergy has no role in the aetiology of antrochoanal polyps. However, the majority of the patients have sinonasal disease. The most common pre-operative radiological finding is the mucocoele-like appearance, which has also been confirmed in surgery. It is remarkable that antrochoanal polyps have recurred in 4 out of 8 patients, who have underwent simple intranasal polypectomy and inferior turbinectomy. As compared to conventional technique, the endoscopic approach proves to be superior.

Abstract
In this study of 22 patients with laryngeal cancer, computed tomographic (CT) scans in the axial plane were compared with histopathological sections prepared in the same plane. The value of the preoperative CT for evaluating tumor invasion, location and size was then investigated. Findings demonstrated that CT was most sensitive in determining tumor invasion to the paralaryngeal and preepiglottic spaces, anterior and posterior commissures and subglottis. In contrast, CT was less sensitive in determining actual tumor invasion to the laryngeal cartilages, extralaryngeal tissues and metastases to cervical lymph nodes.
