Abstract
Merkel cell carcinoma (MCC) and small cell lung cancer (SCLC) can be histologically similar. Immunohistochemistry (IHC) for cytokeratin 20 (CK20) and thyroid transcription factor 1 (TTF-1) are commonly used to differentiate MCC from SCLC; however, these markers have limited sensitivity and specificity. To identify new diagnostic markers, we performed differential gene expression analysis on transcriptome data from MCC and SCLC tumors. Candidate markers included atonal BHLH transcription factor 1 (ATOH1) and transcription factor AP-2β (TFAP2B) for MCC, as well as carcinoembryonic antigen cell adhesion molecule 6 (CEACAM6) for SCLC. Immunostaining for CK20, TTF-1, and new candidate markers was performed on 43 MCC and 59 SCLC samples. All three MCC markers were sensitive and specific, with CK20 and ATOH1 staining 43/43 (100%) MCC and 0/59 (0%) SCLC cases and TFAP2B staining 40/43 (93%) MCC and 0/59 (0%) SCLC cases. TTF-1 stained 47/59 (80%) SCLC and 1/43 (2%) MCC cases. CEACAM6 stained 49/59 (83%) SCLC and 0/43 (0%) MCC cases. Combining CEACAM6 and TTF-1 increased SCLC detection sensitivity to 93% and specificity to 98%. These data suggest that ATOH1, TFAP2B, and CEACAM6 should be explored as markers to differentiate MCC and SCLC.

Abstract
In individuals with subjective cognitive impairments (SCI) the risk for the development of a neurodegenerative disease is assumed to be increased. However, it is not clear which factors contribute to the expression of SCI: Is it related to the cognitive resources already challenged, or is the psycho-affective state of more relevance? Using a novel online assessment combining self-report questionnaires and neuropsychological psychometric tests, significant predictors for the level of complaints were identified in two samples of elderly individuals: Help-seekers (HS, n = 48) consulting a memory clinic and a matched sample of non-help-seekers (nHS, n = 48). Based on the results of the online assessment, the SCI level was found to be significantly determined by the psycho-affective state (depressive mood) in the nHS group, whereas cognitive performance (cued recall) was the main predictor in the HS group. The predictive value of recall performance, however, is more-strongly expressed in memory tests which reduce the impact of compensatory strategies (face-name-association vs. word lists). Our results indicate that the problem-focused behavior of help-seeking individuals is also associated with a higher sensitivity for cognitive deficits-which can be uncovered with an appropriate psychometric test. Considering these factors, the conversion risk in individuals with SCI can probably be determined more reliably.

Abstract
BACKGROUND Associations between body mass index (BMI) and psychological distress (PD) have been reported; however, few longitudinal studies have accounted for likely life-course differences in BMI and PD stability, consistency, and their interplay across time. METHODS Via random intercepts cross-lagged panel models, we assessed the predictive effects (from BMI to PD or vice-versa) across the last two centuries in the Coronary Artery Risk Development in Young Adults [CARDIA, beginning in 1985-6] study using the Center for Epidemiological Studies-Depression Scale [CES-D], and in the National Child Development Study [NCDS, beginning in 1958] and British Cohort Study [BCS, beginning in 1970] using the Malaise Inventory [MI]), assessed at least 4 times in adult life. FINDINGS In CARDIA (n = 4724), NCDS58 (n = 7149) and BCS70 (n = 5967), autoregressive effects were stronger for BMI than for PD, meaning that carry-over effects from one occasion to the next were larger for BMI than for PD. Small interindividual correlations between traits of higher BMI and higher PD were identified among females (rfemale<|0·2|) but not males (rmale<|0·03|) in CARDIA and NCDS. Cross-lagged effects were very weak or close to zero (standardized effects η<|0·1|). INTERPRETATION In the United States, depressive symptoms and BMI were positively correlated at the trait level among females. In the United Kingdom, relationships between PD and BMI were inconsistent between generations, with effect sizes of unlikely clinical importance, indicating negligible dominance of an intraindividual effect of BMI on PD or vice versa.

Abstract
BACKGROUND Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal neoplasm with intermediate malignant potential. Although most often seen in the lungs, it can occur at multiple anatomical locations, including the gastrointestinal tract. An esophageal lesion is extremely rare, however. IMTs present most commonly in children and young adults. The main therapeutic approach is surgical resection. CASE REPORT We report on the follow-up of a case in a 13-year-old boy with IMT in the esophagus. He underwent surgical resection in 2013 and is free of disease to date. CONCLUSION Surgical resection is the most preferred therapy. If the resection is complete, the risk of recurrence is low. Nevertheless, every patient should be carefully followed up after the resection.

Introduction
Ventriculoarterial coupling (VAC) is an important surrogate measurement of global cardiovascular efficiency. However, up till recently, this measurement has been rarely used in clinical practice. This could be due to its invasive nature, and the relatively complex methods required for acquisition and interpretation. We here describe a noninvasive method of measuring VA coupling using cardiac magnetic resonance (CMR) in a cohort of hypertrophic cardiomyopathy (HCM).
Methods
Cardiac MRI was performed in 61 patients with hypertrophic obstructive cardiomyopathy (HOCM) before and after undergoing extended surgical myectomy. Cardiac MRIs from 15 patients with non-obstructive HCM were also included for comparison. Hypertensive patients were excluded from this study. Vitals signs were recorded during each MRI study. Arterial end-systolic pressure (AESP) was determined non-invasively as previously described (0.9x brachial blood pressure). Left ventricular end-systolic pressure (LVESP) was calculated by adding the echo-derived peak systolic gradient across the left ventricular outflow tract to the arterial end-systolic pressure. Indexed stroke volume (SVI) in the ascending aorta as well as indexed end systolic volume (ESVI) were calculated from CMR. Indexed arterial (Ea) and ventricular (Ev) elastance were calculated as AESP/SVI and LVESP/ESVI. VA coupling was then calculated as Ea/Ev.
Results
Compared to the baseline measurements, VAC increased significantly post myectomy (mean VAC pre-myectomy and post-myectomy 0.38 vs. versus 0.62 respectively, p= 0.00001). VAC in non-obstructive HCM patients (mean = 0.64) was statistically similar to that in post-myectomy (p = 0.82) and statistically different from pre-myectomy (p = 0.00016). The mean of LVOTO gradients post- and pre-myectomy were significantly different (p = 0.00001). Significant correlation of the delta-VAC with the delta gradient in the LVOTO was found (r= 0.35, p = 0.005).
Conclusion
Non-invasive assessment of VA coupling using CMR is feasible and could be a useful tool in the evaluation of patients with various cardiovascular disorders. Further studies with larger numbers of patients are required to establish the utility of this method in clinical practice.

Abstract
Paragangliomas represent a group of neuroendocrine tumours which occur in various localizations. Most of them produce catecholamines, and in advanced cases present with typical symptoms and signs such as palpitations, headache and hypertension. The only curative treatment is radical resection. About one-quarter of paragangliomas are malignant, defined by the presence of distant metastases. There are multiple treatment options for unresectable metastatic tumours. They include radionuclid therapy, chemotherapy, and radiotherapy, although none of them are curative. Cytoreductive surgery can also be considered, especially when the goal is to decrease symptoms related to advanced disease. We present a rare case of a large paraganglioma of the left retroperitoneum. Despite radical surgery, early recurrence of the disease was observed.

Abstract
BACKGROUND The trajectories of psychological distress differ between individuals, but these differences can be difficult to understand because the measures contain both consistent and situational features; however, in longitudinal studies these sources of information can be disentangled. In addition to occasion-specific features, interindividual differences can be decomposed into two sources of information: trait and carry-over effects between neighboring occasions that are not related to the trait (i.e. accumulated situational effects). METHODS To disentangle these three sources of variance throughout adulthood, the consistency (trait and accumulated situational effects) and occasion specificity of nine indicators of psychological distress from the Malaise Inventory were examined in two birth cohorts, the 1958 National Child Development Study (NCDS58), and the 1970 British Cohort Study (BCS70). RESULTS The scale was administered at ages 23, 33, 42, and 50 in NCDS58 (n = 7147), and at ages 26, 30, 34, and 42 in BCS70 (n = 6859). For each psychological symptom, more variance was consistent than occasion-specific. The majority of the consistency was due to trait variance as opposed to accumulated situational effects, indicating that an individual predisposed to be distressed at the beginning of the study remained more likely to be distressed over the whole period. Symptoms of rage were notably more consistent among males than females in both cohorts (78.1% and 81.3% variance explained by trait in NCDS58 and BCS70, respectively), and among females in the NCDS58 (69%). CONCLUSIONS Symptoms of psychological distress exhibited high stability throughout adulthood, especially among men, due mostly to interindividual trait differences.

Abstract
Hyperinsulinemia is the hallmark of the development of insulin resistance and precedes the diagnosis of type 2 diabetes. Here we evaluated the effects of prolonged exposure (≥4 days) to high insulin doses (150 nM) in vitro in two adipose cell types, mouse 3T3-L1 and human SGBS. Chronic insulin treatment significantly decreased lipid droplet size, insulin signalling and insulin-stimulated glucose uptake. 3T3-L1 displayed an increased basal glucose internalization following chronic insulin treatment, which was associated with increased GLUT1 expression. In addition, both cells showed increased basal lipolysis. In conclusion, we report the effects of prolonged hyperinsulinemia in 3T3-L1 and SGBS, highlighting similarities and discrepancies between the cell types, to be considered when using these cells to model insulin-induced insulin resistance.

Abstract
Pancreatic carcinoma is an aggressive tumor with a grim prognosis. Accurate staging is essential for indicating surgery in patients with borderline resectable tumors. This paper examines the correlation between pre-operation characteristics of tumors found on CT, infiltration of individual resection margins as confirmed by a pathologist, and the survival of patients with resectable pancreatic head ductal adenocarcinoma. This prospective cohort study involved patients operated on for pancreatic head adenocarcinoma, which was clearly resectable based on the staging CT and intraoperative observation between 2011-2014. Only patients without postoperative complications who underwent adjuvant chemotherapy were analyzed. Seventy-nine patients were assessed, of which 16 (20.3%) had R0 resection and 63 (79.7%) had R1 resection. Patients with R1 results had up to 2.7 times higher risk of death than patients with R0 resection. We found a trend towards shorter survival associated with a closer relationship of the tumor to the superior mesenteric vein/portal vein (SMV/PV) wall in the pre-operation CT examination. Patients with a tumor interface between the vein wall of up to 180 ° circumference had up to 1.97 times higher risk of death than patients without (p=0.131). The results of our work confirmed that in our center, even surgically treated, clearly resectable pancreatic head tumors still have a high occurrence of positive surgical margins (R1 resection) and that tumors with R1 resection had statistically significantly reduced survival compared to R0 resection. A trend for shorter overall survival was found after tumor resection depending on the increasing interface between the tumor and the SMV/PV wall, but this result was not statistically significant.

Abstract
INTRODUCTION Transanal total mesorectal excision (TaTME) is a relatively new approach in surgical treatment of rectal cancer. There are no clear indications when to choose this strategy. It is a technically demanding procedure for the surgeon with a long learning curve, which should also be taken into account in evaluation of this method. The results of both oncological and postoperative complications must be properly evaluated to explore the benefit of TaTME. The aim of this study is to assess the potential benefit of TaTME compared to other alternatives in middle and distal rectal tumors. METHODS Retrospective evaluation of patients undergoing TaTME procedure performed by one team of surgeons between October 2014 and June 2019. The authors analyzed demographic indicators of the group of patients, tumor characteristics, specimen quality, early postoperative complications and the possibility of stoma reversal. RESULTS A total of 93 patients underwent TaTME procedure for middle and distal rectal cancer. Mean BMI was 27.6 (4.8). T3 or T4 tumor was found in 73 (78.5%) patients, 68 (73.1%) patients had positive lymph nodes and 12 (12.9%) patients were treated for synchronous metastatic rectal cancer. Neoadjuvant therapy was used in 80 (86%) patients. Conversion to open laparotomy was necessary in one case (1%). Stapled anastomosis was performed in 37 (39.7%) cases, handsewn in 56 (60.2%). A positive circumferential resection margin (CRM) was found in 10 (10.7%) cases. Distal resection margin (DRM) was positive in 3 (3.2%) patients. Pathological analysis showed a complete mesorectum in 18 patients (19.4%), nearly complete in 39 (41.9%) and an incomplete mesorectum in 36 (38.7%). Complications in the first 30 days after primary surgery were observed in 38 (40.8%) patients, mainly for anastomotic leak (19 patients, 20.4%). Reoperation was required in 7 (7.5%) patients. Permanent colostomy had to be performed in 4 (4.3%) cases. No patient died after surgery. CONCLUSION In a selected group of patients it is possible to perform resection using this approach with acceptable postoperative morbidity and quality of the specimen. We used TaTME procedure in patients expected to have difficult TME due to obesity, size and distal localization of tumor. The incidence of conversion to open surgery was very low. Further studies for long term oncological outcomes are needed.

Abstract
OBJECTIVES The purpose of this study was to analyze the prognostic value of dynamic CT perfusion imaging (CTP) and CT derived fractional flow reserve (CT-FFR) for major adverse cardiac events (MACE). METHODS 81 patients from 4 institutions underwent coronary computed tomography angiography (CCTA) with dynamic CTP imaging and CT-FFR analysis. Patients were followed-up at 6, 12, and 18 months after imaging. MACE were defined as cardiac death, nonfatal myocardial infarction, unstable angina requiring hospitalization, or revascularization. CT-FFR was computed for each major coronary artery using an artificial intelligence-based application. CTP studies were analyzed per vessel territory using an index myocardial blood flow, the ratio between territory and global MBF. The prognostic value of CCTA, CT-FFR, and CTP was investigated with a univariate and multivariate Cox proportional hazards regression model. RESULTS 243 vessels in 81 patients were interrogated by CCTA with CT-FFR and 243 vessel territories (1296 segments) were evaluated with dynamic CTP imaging. Of the 81 patients, 25 (31%) experienced MACE during follow-up. In univariate analysis, a positive index-MBF resulted in the largest risk for MACE (HR 11.4) compared to CCTA (HR 2.6) and CT-FFR (HR 4.6). In multivariate analysis, including clinical factors, CCTA, CT-FFR, and index-MBF, only index-MBF significantly contributed to the risk of MACE (HR 10.1), unlike CCTA (HR 1.2) and CT-FFR (HR 2.2). CONCLUSION Our study provides initial evidence that dynamic CTP alone has the highest prognostic value for MACE compared to CCTA and CT-FFR individually or a combination of the three, independent of clinical risk factors.

Abstract
BACKGROUND Gastrointestinal stromal tumours (GIST) are rare malignant mesenchymal tumours with an incidence of 1 in 100,000. They represent only 5% of gastrointestinal tumours. The GISTs are mainly located in the stomach (60-70%) and in the rectum in < 5% of cases. In the case of localized, resectable tumours, the treatment is surgical resection. Depending on the size and localization of the tumour in the rectum, either a local excision, rectal resection with anastomosis, or abdominoperitoneal amputation with permanent stoma can be performed. In contrast to carcinomas, the metastasis of GISTs into lymph nodes is rare; therefore, from an oncological point of view, lymphadenectomy in the form of mesorectal excision is not required. Neoadjuvant treatment using tyrosine-kinase inhibitors (TKI) is recommended for tumours larger than 5 cm and in case of tumours infiltrating surrounding organs or sphincters in order to achieve complete resectability, less mutilating and continent procedure. In GISTs with a positive resection line, re-resection can be attempted. Adjuvant TKI therapy can be considered in cases of CD117 positivity and after resections of GISTs with medium and high-risk malignant behaviour. The TKI treatment is also indicated in cases of unresectable and metastatic GISTs. METHODS Data obtained from the GIST registry by the 1st January 2017, when 10 centres in the Czech Republic were contributing to the registry, were analysed. RESULTS We analysed 1,095 patients out of which 45 (4.1%) had GIST localized in the rectum. The average age of the patients was 60 years. There were significantly more males (68.9%; p = 0.0007) and symptomatic patients (62.2%; p = 0.034). In total, 82% of the patients underwent surgery. Local excision was performed in 37.8%, resection of the rectum with anastomosis in 29.7%, and Miles operation in 29.7%. In the cohort, most tumours were 2-5 cm in size and almost half of the tumours presented a high risk of malignant behaviour. Systemic treatment was reported in 73% of patients. A complete remission was achieved in 80% of patients with GIST of the rectum. The median survival rate was 11.3 years and the 5-year survival rate is 90.6%. CONCLUSION Despite the success of TKI treatment, the only potentially curative method of rectal GISTs is a surgical R0 resection. Given the relatively rare frequency of these tumours, proper diagnosis and treatment is demanding. Therefore, these patients should be preferably treated in specialised centres.

Abstract
OBJECTIVE Longitudinal and cross-sectional studies suggest that affective instability is inversely related to greater age in borderline personality disorder (BPD). However, existing studies relied on retrospective self-reports of perceived instability. We examined affective instability in everyday life in patients with BPD and healthy controls (HCs) by age in a cross-sectional e-diary study. METHODS Two hundred and sixty female participants between 14 and 53 years of age (130 patients with BPD and 130 HCs) carried an e-diary over 4 days. The e-diaries emitted a prompting signal in approximately hourly intervals asking participants to rate their current affective state, that is valence (ranging from pleasant to unpleasant) and tense arousal (ranging from calm/relaxed to restless/under tension). RESULTS Multilevel analyses revealed a significant interaction of age and group predicting affective instability (valence: F(1,255.6) = 7.59; P < 0.01; tense arousal: F(1,252) = 6.08; P < 0.01), suggesting that affective instability significantly declines with greater age in patients with BPD. Controlling for the number of comorbid disorders and BPD severity did not change the results, illustrating an inverse relationship between age and affective instability in BPD (significant interaction of age*group for valence: F(1,238.7) = 5.74; P < 0.02 and tense arousal: F(1,235.2) = 5.28; P < 0.02). CONCLUSION Affective instability during daily life declines with greater age in BPD. This decline is irrespective of comorbidity and BPD severity.

Abstract
CONTEXT Multiple endocrine neoplasia type 2B (MEN2B) is a rare autosomal-dominant cancer syndrome characterized in part by metastatic medullary thyroid cancer (MTC) and pheochromocytoma. Cushing disease is a rare cause of endogenous hypercortisolism in children. CASE DESCRIPTION We describe a 21-year-old African-American male who was diagnosed at age 10 with an ACTH-secreting pituitary microadenoma. At age 16 he developed medullary thyroid cancer and was found to have multiple endocrine neoplasia type 2B with the characteristic M918T mutation of the RET proto-oncogene. Following thyroidectomy, he was initiated on Vandetanib, a tyrosine kinase inhibitor, and has since had stable disease over the last 5 years. CONCLUSIONS Our patient is the first individual with MEN2B to be described with Cushing disease. The RET oncogene may play a role in pituitary tumorigenesis; alternatively, the coexistence of these two entities may represent an extremely rare coincidence.

Abstract
Although Objective Personality Tests (OPTs) have a long history in psychology and the field of psychological assessment, their validity, and reliability have not yet been sufficiently studied. In this study, we examined the convergent and discriminant validity of objective (personality) tests, Implicit Association Tests (IATs), and self-report measures for the assessment of conscientiousness and intelligence. Moreover, the convergent and discriminant validity of these measures was assessed on the trait (stable) and occasion specific (momentary) level by using the multimethod latent state-trait (MM-LST) model proposed by Courvoisier, Nussbeck, Eid, and Cole (2008) which allows for the decomposition of different sources of variance. Data from 367 students assessed on three different measurement occasions was incorporated. Results indicate generally low convergence of OPTs with data gained by other approaches. Additional analyses revealed that the OPTs used assess stable rather than momentary components of the constructs. Reliabilities of different tests ranged from .54 to .95. Furthermore, a substantial amount of trait method specificity revealed that different methods assess trait components that are not shared between OPTs and other measures. Data on the criterion validity of the objective conscientiousness test revealed that it is related to the punctuality of test takers in the laboratory.

Abstract
Antimicrobial activity of silver nanoparticles is gaining importance due its broad spectrum of targets in cell compared to conventional antimicrobial agents. In this context, silver nanoparticles were synthesized by gamma irradiation-induced reduction method of acrylamide and itaconic acid with irradiation dose up to 70 kGy. Silver nanoparticles were examined by Fourier-transform infrared, scanning electron microscopic images (SEM), and ultraviolet-visible spectrophotometer. The particle size was determined by X-ray diffraction, transmission electron microscopy (TEM), and dynamic light scattering. The antibacterial effect was studied by disk diffusion method against some bacterial pathogenic strains. Silver nanoparticles showed promising activity against Pseudomonas aeruginosa and slightly active against Escherichia coli, methicillin-resistant Staphylococcus aureus, and Klebsiella pneumonia. The bactericidal effect of silver nanoparticles was tested against P. aeruginosa. The killing rate of P. aeruginosa was found to be 90 % of viability at (100 μl/ml) of silver nanoparticles. Exposure of P. aeruginosa cells to silver nanoparticles caused fast loss of 260 nm absorbing materials and release of potassium ions. The TEM and SEM observation showed that silver nanoparticles may destroy the structure of bacterial cell membrane in order to enter the bacterial cell resulting in the leakage of the cytoplasmic component and the eventual death.

Abstract
e15083 Background: Bevacizumab (BV) increases responses and survival rates when used with chemotherapy in metastatic colorectal cancer (CRC). Current practice is to give peri-operative chemotherapy for resectable CRC liver metasases (LM). The safety and efficacy of chemo-BV in this setting is unknown. Post-operative complications have been reported in patients (pts) who underwent surgery while receiving BV. The goals were to determine safety of perioperative BV. Methods: In a prospective pilot study, patients with resectable LM from October 2005 to 2008 that received BV perioperatively along with chemotherapy. Of a total of 60 pts, 34 had oxaliplatin-based CTX, 22 CPT-11 (FOLFIRI) and 4 IROX. All but seven pts received BV pre and postoperatively. The average age was 55 years. All patients underwent liver surgery 6–8weeks post last dose of BV. Univariate Cox regression models were used to evaluate the association of patient and tumour characteristics, therapy and postoperative complications. Results: Postoperative complications developed in a total of 24 pts (40%). 12 pts (35%) who received Oxaliplatin CTX + BV, 9 pts (40%) with CPT 11 CTX + BV and 3 pts (75%) with Oxaliplatin + CPT-11 CTX +BV. The average time from BV discontinuation to surgery was 49 days. No significant associations were identified between BV and CTX regimen or timing and postoperative complications. Wound healing complication were most frequent with 8 pts (13%), DVT diagnosed in 6 pts (10%), protracted pancytopenia 4 pts (7%), sepsis 1pt, infections 2pts, MI 1pt, acute cardiomyopathy 1pt, and billiary leak 1pt. No bowel perforations or sudden deaths were reported. These side effects apart from thromboembolic events are comparable to previously reported post-operative complications. Conclusions: Neither the use of BV with CTX nor timing of BV administration were associated with a non acceptable increase in complication rates as compared to previously published by EORTC intergroup. Our data confirm that the combination of BV with neoadjuvant chemotherapy is feasible and safe in patients CRC LM. A higher incidence of thromboembolic events was seen. To determine the optimal timing and drug combination prospective randomized trials are urgently required. [Table: see text]

Abstract
e15027 Background: Colorectal liver metastases treated with perioperative chemotherapy were previously shown to increase progression free survival. Given the survival benefit of bevacizumab in metastatic CRC, the aim of this study was to assess the efficacy and safety of bevacizumab based chemotherapy in the perioperative setting. Methods: In this single arm prospective pilot study, patients with resectable LM eligible to receive perioperative BV and chemotherapy were included. Kaplan Meier survival analysis was used to calculate overall survival and progression free survival. Results: A total of 60 patients were recruited, 41 male, with an average age of 55. Forty-three patients had synchronous LM. All but seven patients received pre and post-operative BV-based chemotherapy (34/60 oxaliplatin based, 22/60 CPT-11 based and 4/60 CPT-11 and oxaliplatin based). All patients underwent hepatectomy 6–8 weeks post last dose of BV. Overall response rate was 80% (48/60), 4pt with stable diseaase; 10% had a complete pathological response and 27% had no evidence of disease post hepatectomy with a median follow up of 33 months.8 patients progressed prior to surgery. Overall survival (OS) rates at 12, 24, 36 and 48 months were: 100%, 86%, 74% and 66% respectively and 5 year median survival of 55%. Progression free survival (PFS) was 14 months. Subgroup analysis of the data according to the chemotherapy pts received showed that PFS in the CPT-11 and the oxaliplatin arm were 13 and 15 months respectively. Most of the adverse events recorded were associated with the post-operative period and included wound healing (8pts), infections (2pts) and thromboemblic (6pts) disease. No sudden deaths or bowel perforations were reported. Conclusions: Bevacizumab-containing chemotherapy regimens in the peri-operative setting is effective in patients with colorectal liver metastases. Our 80% response rate and 10% complete pathological response is one of the highest reported and warrants further investigation in phase III trials. [Table: see text]

Abstract
A simple, sensitive, rapid and accurate spectrophotometric method was developed for the determination of risedronate, a bisphosphonate drug important for the treatment of a variety of bone diseases, in raw material and pharmaceutical formulations. The proposed method is based on complex formation between risedronate and Cu (II) ions in acetate buffer of pH5.5. The optimum conditions for this reaction were ascertained and a spectrophotometric method was developed for the determination of risedronate in concentration range of 2-40 μg/mL with detection limit of 0.03 μg/mL (9.51 × 10(-8) mol/L). The molar absorbtivity was 8.00 × 10(3) l/mol/cm. The method was successfully applied for the determination of risedronate in tablet dosage form with mean percentage recovery of 101.04 ± 0.32. The results obtained were favorably compared with those obtained by the comparison method. Furthermore, the proposed method was applied for content uniformity testing of risedronate tablets.

Abstract
A simple and sensitive kinetic method is described for the determination of ketoprofen in pure form, pharmaceuticals and biological fluids. The method utilizes an oxidative- coupling reaction based upon oxidation of 3-methyl-2-benzo-thiazolinone hydrazone hydrochloride (MBTH) with Ce(IV) in presence of HCl, where an electrophilic intermediate (diazonium salt of the reagent) is produced, then couples with ketoprofen yielding a highly colored condensation product. The absorbance is measured after 20 min at 605 nm. Calibration graph was linear over the concentration range of 1-8μg/mL with a minimum detection limit of 0.07 μg/mL. The proposed method was applied successfully to the determination of Ketoprofen in pharmaceutical preparations, plasma and urine. The % recoveries were 100.11 for pure form, 100.10 for tablets and gel, 100.0 for suspension and suppositories, 100.2 for capsules and ampoules and 99.79, 99.9 for plasma and urine. The results obtained were in good agreement with those obtained using reference methods for comparison.
