Abstract
Fragile X syndrome (FXS) is the most common form of inherited intellectual disability and autism. The protein (FMRP) encoded by the fragile X mental retardation gene (FMR1), is an RNA-binding protein linked to translational control. Recently, in the Fmr1 knockout mouse model of FXS, dysregulated translation initiation signaling was observed. To investigate whether an altered signaling was also a feature of subjects with FXS compared to typical developing controls, we isolated total RNA and translational control proteins from lymphocytes of subjects from both groups (38 FXS and 14 TD). Although we did not observe any difference in the expression level of messenger RNAs (mRNAs) for translational initiation control proteins isolated from participant with FXS, we found increased phosphorylation of the mammalian target of rapamycin (mTOR) substrate, p70 ribosomal subunit 6 kinase1 (S6K1) and of the mTOR regulator, the serine/threonine protein kinase (Akt), in their protein lysates. In addition, we observed increased phosphorylation of the cap binding protein eukaryotic initiation factor 4E (eIF4E) suggesting that protein synthesis is upregulated in FXS. Similar to the findings in lymphocytes, we observed increased phosphorylation of S6K1 in brain tissue from patients with FXS (n = 4) compared to normal age-matched controls (n = 4). Finally, we detected increased expression of the cytoplasmic FMR1-interacting protein 2 (CYFIP2), a known FMRP interactor. This data verify and extend previous findings using lymphocytes for studies of neuropsychiatric disorders and provide evidence that misregulation of mTOR signaling observed in the FXS mouse model also occurs in human FXS and may provide useful biomarkers for designing targeted treatments in FXS.

Abstract
BACKGROUND AND PURPOSE Retinoblastoma may exhibit variable hyperintensities on DWI, resulting in different values in the ADC maps, depending on their histology and cellularity. However, EP-based DWI has susceptibility artifacts and image distortions, which make DWI of the orbit a challenging technique. The aim of this study was to investigate the feasibility of single-shot turbo spin-echo (HASTE) DWI in the evaluation of children with retinoblastoma and to assess the value of ADC maps in differentiating viable and necrotic tumor tissue. MATERIALS AND METHODS Two radiologists assessed conventional MR images, DWI, and ADC maps of 17 patients with retinoblastoma (n = 17 eyes). Non-EP DWI was performed by using a HASTE sequence with b-values of 0 and 1000 s/mm(2). ADC values were measured for enhancing and nonenhancing tumor tissue. ADC maps were compared with histopathologic findings regarding tumor differentiation and viability. RESULTS On DWI, vital tumor tissue showed hyperintensity with negligible intensity of surrounding vitreous. The difference in mean (range) ADC values between enhancing (1.03 [0.72-1.22] × 10(-3) mm(2) s(-1)) and nonenhancing (1.47 [0.99-1.80] × 10(-3) mm(2) s(-1)) parts of retinoblastoma was statistically significant (P < .0005). Nonenhancing tumor parts showed a significantly lower ADC compared with vitreous (2.67 [2.24-3.20]×10(-3) mm(2) s(-1)) (P < .0005) and subretinal fluid (2.20 [1.76-2.96] × 10(-3) mm(2) s(-1)) (P < .0005). Histopathologically, low ADC values (enhancing tumor part) correlated to viable tumor tissue, whereas intermediate ADC values (nonenhancing tumor parts) correlated to necrotic tumor tissue. CONCLUSIONS HASTE DWI allowed adequate characterization of retinoblastoma, and ADC is a helpful tool to differentiate viable and necrotic tumor tissue and might be valuable in monitoring the response to eye-preserving therapies.

Abstract
BACKGROUND The thickness of the cortical mantle is a sensitive measure for identifying alterations in cortical structure. We aimed to explore whether first episode schizophrenia patients already show a significant cortical thinning and whether cortical thickness anomalies may significantly influence clinical and cognitive features. METHOD We investigated regional changes in cortical thickness in a large and heterogeneous sample of schizophrenia spectrum patients (n=142) at their first break of the illness and healthy controls (n=83). Magnetic resonance imaging brain scans (1.5 T) were obtained and images were analyzed by using brains2. The contribution of sociodemographic, cognitive and clinical characterictics was investigated. RESULTS Patients showed a significant total cortical thinning (F=17.55, d=-0.62, p<0.001) and there was a diffuse pattern of reduced thickness (encompassing frontal, temporal and parietal cortices) (all p's<0.001, d's>0.53). No significant group×gender interactions were observed (all p's>0.15). There were no significant associations between the clinical and pre-morbid variables and cortical thickness measurements (all r's<0.12). A weak significant negative correlation between attention and total (r=-0.24, p=0.021) and parietal cortical thickness (r=-0.27, p=0.009) was found in patients (thicker cortex was associated with lower attention). Our data revealed a similar pattern of cortical thickness changes related to age in patients and controls. CONCLUSIONS Cortical thinning is independent of gender, age, age of onset and duration of the illness and does not seem to significantly influence clinical and functional symptomatology. These findings support a primary neurodevelopment disorder affecting the normal cerebral cortex development in schizophrenia.

Abstract
Newborn rat distal cells express an apical Ca2+ channel activated by dihydropyridine drugs. Similarly, in Madin-Darby canine kidney (MDCK) cells, nifedipine increased Ca2+i in a concentration-dependent manner (IC50=4 μM) in fura-2-loaded cells. Response to nifedipine was abolished by EGTA, suggesting that it depends on extracellular calcium. Ca2+ channel antagonist isradipine and agonist BayK8644 increased Ca2+i indicating that this effect is related to the dihydropyridine group. Diltiazem (20 μM) and gadolinium (200 μM) decreased the nifedipine effect (62 and 43%, respectively). Lanthanum (100 μM) did not change the response. Valinomycin clamping of the membrane potential did not modify nifedipine-induced increment, indicating that it was unrelated to potassium fluxes. We performed whole cell clamp experiments in MDCK cells maintained at -50 mV with perfusion solution containing 10 mM CaCl2. Nifedipine (20 μM) induced an increase in current (1.2±0.3 nA), which was partially inhibited by Gd3+. No significant current was induced by nifedipine in the presence of 0.5 mM EGTA. To determine the effects of nifedipine on the membrane potential, we performed oxonol fluorescence experiments. The addition of nifedipine or Bay K8644 induced depolarization, highly dependent on external sodium. Nifedipine (20 μM) induced depolarization of 6.9±0.8 mV (n=21). EC50 to nifedipine was in the 10 μM range. We conclude that MDCK cells exhibit a dihydropyridine-activated cationic channel.

Abstract
OBJECTIVE To evaluate a support program for patients co-infected with the human immunodeficiency virus and tuberculosis in terms of its impact on clinical outcomes and resource utilization. METHODS We compared co-infected patients receiving Community-Based Accompaniment with Supervised Antiretrovirals (CASA) with matched patients receiving standard of care (control group) in two health districts of Lima, Peru. We recorded clinical outcomes, costs of the intervention, and health care utilization by each patient during 24 months of follow-up. RESULTS There were 33 patients in each group, representing 58.0 person-years (py) in the CASA group and 45.6 py in the control group. At 24 months of follow-up, the CASA group had a lower hazard of dying or defaulting from treatment (HR adj 0.34, 95%CI 0.12-0.98), experienced fewer hospital days (IRR adj 0.37, 95%CI 0.14-0.99) and had fewer out-patient visits (IRR adj 0.75, 95%CI 0.63-0.89). Assigning costs to significantly different measures of health care utilization using WHO-CHOICE (World Health Organization-Choosing interventions that are cost effective) data, CASA was associated with savings of US$551/py. Considering intervention costs of US$2097/py, the net costs of CASA were US$1546/py. CONCLUSIONS Our intervention was associated with clinical improvements and reduced health care utilization, which significantly offset the cost of the intervention over 2 years of follow-up.

Abstract
AbstractWe show that the conductivity maximum, well known for salt-in-polymer electrolytes is not the maximum conductivity in the system when the salts used are chosen for their resistance to crystallization at high concentration. The polymer + salt system, with increasing salt content, goes through a transition zone characterized by a maximum in glass transition temperature. Beyond this point additional salt serves to plasticize the salt-crosslinked polymer system, establishing thereby a region of increasing conductivity in which the conductivity can reach very large values. We show that “polymer in-salt” solutions constitute a new type of rubbery solid electrolyte in which the conductivity is dominated by cation motion. Such systems are true hybrids of the previously distinct “superionic glass” and “polymer electrolyte” types of amorphous solid conductors.

Abstract
Toxigenic fungi invade crops prior to harvest as well as during storage and produce harmful, even carcinogenic toxins such as aflatoxins. Since consumers demand safe commodities, and due to enhanced public awareness of the dangers of many synthetic fungicides, the importance of investigating alternative, natural products to control these toxigenic fungi is clear. This study investigated the effect of aqueous extracts of Agave americana on growth, conidia and aflatoxin production. Aspergillus parasiticus strains SRRC 148, SRRC 143 (Su-1), and A. parasiticus SRRC 162, a mutant (nor-) that accumulates norsolorinic acid (NOR, an orange-coloured intermediate of the aflatoxin pathway), were first inoculated into Adye and Mateles liquid medium, then plant extracts were added, and incubated at 28 °C for 7 days. Aflatoxin and norsolorinic acid were assayed by HPLC and spectrophotometry, respectively. While the extract of A. americana stimulated growth of the studied fungi, conidiogenesis, norsolorinic acid accumulation (in the nor- mutant), and aflatoxin production were significantly affected. The reduction was produced by the extracts at concentrations higher than 5-10 mg/ml, where all types of total aflatoxin analysed (aflatoxins B1, B2, G1 and G2) were reduced from 64% to >99% in the whole culture, and a reduction of 75% of norsolorinic acid. The results of the present work indicate that extracts of A. americana may be promising safe alternatives to harmful fungicides for controlling aflatoxin contamination.

Abstract
Natural and modified zeolites (0.5-1.0 mm) from the Tasajera deposit in Cuba were used to enhance the anaerobic digestion process of synthetic substrates. Natural zeolites were modified by ionic exchange and by adsorption with nickel, cobalt and magnesium. The experiments were carried out by using an inoculum from a full-scale anaerobic reactor treating winery wastewater. Modified natural zeolites not only enhanced the anaerobic digestion process, but also increased the specific methanogenic activity (SMA) of the sludges. The textural and chemical surface characteristics of the modified zeolites were related to the process performance, volatile fatty acid (VFA) production and microbial communities found in the digesters. For the selected dose of modified zeolites [0.05 g/g of volatile suspended solids (VSS)], the lowest concentration was found for cobalt followed by nickel and magnesium. Based on the analyses of anaerobic biofilms, the heavy metal incorporated into the zeolite was shown to have a great influence on the predominance of species. For example, the presence of nickel and cobalt favoured Methanosaeta, while at the same dose magnesic zeolite stimulated the presence of Methanosarcina and sulfate-reducing bacteria (SRB). In digesters with modified zeolites and metal supplementations the values of SMA were higher than those obtained in the control and natural zeolite digesters.

Abstract
BACKGROUND AND PURPOSE Although pineoblastoma is the main brain abnormality associated with hereditary retinoblastoma, recent studies suggest an association with pineal cysts. This association is important because some pineoblastomas mimic pineal cysts. If there is a relationship, then radiologists should be aware of it because diagnostic confusion is possible. Mental retardation and congenital brain anomalies are also reported in patients with retinoblastoma, mostly in combination with 13q deletion syndrome. In this retrospective study, the presence of brain abnormalities on MR images in a large group of consecutive patients with retinoblastoma is evaluated. MATERIALS AND METHODS Brain MR images of 168 patients with retinoblastoma from 1989 to 2009 were evaluated by 2 radiologists for tumors, structural anomalies, myelinization, and coincidental findings. Clinical records were reviewed for laterality, heredity, and the presence of the 13q deletion syndrome. RESULTS The hereditary group (patients with bilateral and unilateral proved RB1-germline mutation) included 90 (54%) of 168 patients. Seven patients had 13q deletion syndrome. Normal findings on brain MR images were seen in 150 (89%) patients. Five pineoblastomas were detected, all in patients with hereditary retinoblastoma (5.5% in the hereditary subgroup). Nine pineal cysts were detected (2.2% in the hereditary subgroup). Corpus callosum agenesis was found in 1 patient and a Dandy-Walker variant in 1 patient, both in combination with 13q deletion syndrome. CONCLUSIONS Pineoblastoma is associated with hereditary retinoblastoma, and structural brain abnormalities are restricted to patients with the 13q deletion syndrome. The incidence of pineal cysts in patients with retinoblastomas is similar to that in healthy children and is not associated with hereditary retinoblastoma.

Abstract
Although slow freezing is the method of choice to cryopreserve in vivo-produced ovine embryos, vitrification has became an alternative procedure mostly developed for in vitro-produced bovine embryos. The aim of this work was to compare pregnancy rates after cryopreservation of in vivo-produced ovine embryos with slow freezing or open pulled straw (OPS) vitrification method. Ewes were synchronized using intravaginal sponges containing 60 mg of medroxyprogesterone acetate for 14 d. Superovulation was performed using a total dose of 176 IU of ovine FSH (Ovagen), in 6 decreasing doses (i.m.) from Day 12 to 14 of treatment (Day 0 = sponge placing). Ewes were hand mated with 2 rams of proven fertility. Embryos were recovered 6 days after estrous detection by surgical procedure, evaluated under stereomicroscope, and randomly assigned to the cryopreservation treatments. Slow freezing was performed in D-PBS supplemented with 1.78 M ethylene glycol, 0.1 M sucrose, 4 mg mL-1 of BSA, and 20% serum. Embryos were loaded into 0.25-mL plastic straws and placed into a -7°C methanol bath chamber. After seeding embryos were cooled to -35°C at a rate of 0.5°C/min and then stored in liquid nitrogen. Thawing was performed by placing the straws in a 30°C water bath for 30 sec. Vitrification was performed by using the OPS method (Vajta et al. 1998) with minor modifications. Embryos were incubated in D-PBS supplemented with 1.78 M ethylene glycol, 1.3 M DMSO for 3 min and then transferred for 25 s in vitrification solution of D-PBS with 3.56 M ethylene glycol, 2.6 M DMSO, and 0.5 M sucrose, loaded in a 1 mL drop in the OPS, and immediately submerged into and stored in liquid nitrogen. Warming was performed in D-PBS plus 0.25 M sucrose for 5 min and then into D-PBS plus 0.15 M sucrose for another 5 min. Before embryo transfer, the presence of corpus luteum (CL) was detected by laparoscopic examination. One embryo per recipient was surgically transferred in the apical extreme of the uterine horn ipsilateral to the CL. Pregnancies were determined by ultrasonography 41 days after embryo transfer. Data were analyzed using the chi-square test. We found 47.8% pregnancy rate using slow freezing (11/23) and 43.5% pregnancy rate using OPS vitrification (10/23). Statistical differences were not detected (P = 0.09). We conclude that vitrification by OPS system, with minor modifications, is a suitable procedure for in vivo-produced ovine embryo cryopreservation.

Abstract
This work presents the effect of ammonia nitrogen concentration and zeolite addition on the specific methanogenic activity (SMA) of different anaerobic sludges with various physical structures (granular and flocculent), operating in batch conditions. Piggery, malting production and urban sludges derived from full-scale anaerobic reactors were tested in the experiment as the source of inoculum in batch digesters. It was found that piggery sludge was the most affected by the increase of ammonia nitrogen concentration while malting producing and municipal sludges were less affected. In general, the addition of zeolite at doses in the range of 0.01-0.1 g/g VSS reduced the inhibitory effect of N-NH(4)(+) for piggery sludge (P.S.). For this sludge, the propionic:acetic ratio increased when the concentration of N-NH(4)(+) increased, indicating that methanogenesis was affected. Finally, a study of the microbial population involved in this study for P.S. by using 16S rRNA based molecular techniques revealed a presence of microorganisms following the order: Methanococcaceae > Methanosarcina > Methanosaeta.

Abstract
Four species of fast-growing pioneer tree species in the genus Cecropia exist in the forests in central Panama. Cecropia insignis is dominant in old-growth forests but absent from nearby secondary forests; C. obtusifolia, and C. peltata are abundant in secondary forests but rare in old-growth forest, and C. longipes is uncommon in both. To determine whether Cecropia habitat associations are a consequence of local dispersal or differences in recruitment success, we grew seedlings of these species in common gardens in large treefall gaps in secondary and old-growth forest. In contrast to the observed adult distribution, only C. insignis grew significantly over 16 months in secondary forests; remaining species were heavily browsed by herbivores. C. insignis also grew and survived best in old-growth forest. Differences in susceptibility to herbivory did not result from an ant defence mutualism; none of the plants were colonised by ants during the experiment. To test whether C. insignis, the species least susceptible to herbivory, trades off investment in growth in favour of defence, we also grew the four Cecropia species in a screened growing house under light conditions comparable to large forest gaps. Contrary to expectation, species growth rates were similar; only C. peltata grew significantly faster than C. insignis. These results suggest that (1) conditions in ~40-year-old secondary forests no longer support the recruitment of Cecropia species, which are canopy dominants there; and (2) among congeners, differences in plant traits with little apparent cost to growth can have large impacts on recruitment by affecting palatability to herbivores.

Abstract
OBJECTIVE To determine whether patients with definite multiple sclerosis (MS) and repeated positive anticardiolipin antibody (aCL Ab) testing fulfil the recently updated criteria for the antiphospholipid syndrome (APS). Also, to determine if these patients form a separate subgroup in terms of long term follow-up and MRI characteristics. DESIGN A blinded case control study comparing MRI patterns between aCL Ab positive and negative MS patients with a clinical follow-up of 7 years. PARTICIPANTS 8 (5.6%; male:female ratio 2:6; 6 relapsing-remitting subtype, 1 primary progressive subtype and 1 neuromyelitis optica (NMO)) of 143 consecutive patients with definite MS or NMO (71% relapsing-remitting, 18% secondary progressive and 6% primary progressive disease course; 4% NMO) showed repeated positive aCL Ab testing. SETTING Outpatient clinic of a tertiary MS centre in The Netherlands. RESULTS All eight aCL Ab positive patients had levels below 40 MPL/GPL units, with the majority of intervals between tests of at least 12 weeks. After follow-up, none of the patients fulfilled the criteria for APS. No specific MRI features were present compared with 24 matched aCL Ab negative patients. CONCLUSIONS No aCL Ab positive MS patient fulfilled the criteria for APS, arguing against a possible misdiagnosis or coexistence.

Abstract
OBJECTIVE Central obesity is associated with insulin resistance through factors that are not fully understood. We studied the effects of three different isocaloric diets on body fat distribution, insulin sensitivity, and peripheral adiponectin gene expression. RESEARCH DESIGN AND METHODS Eleven volunteers, offspring of obese type 2 diabetic patients with abdominal fat deposition, were studied. These subjects were considered insulin resistant as indicated by Matsuda index values <4 after an oral glucose tolerance test, and they maintained A1C <6.5% without therapeutic intervention. All subjects underwent three dietary periods of 28 days each in a crossover design: 1) diet enriched in saturated fat (SAT), 2) diet rich in monounsaturated fat (MUFA) (Mediterranean diet), and 3) diet rich in carbohydrates (CHOs). RESULTS Weight, body composition, and resting energy expenditure remained unchanged during the three sequential dietary periods. Using dual-energy X-ray absorptiometry we observed that when patients were fed a CHO-enriched diet, their fat mass was redistributed toward the abdominal depot, whereas periphery fat accumulation decreased compared with isocaloric MUFA-rich and high-SAT diets (ANOVA P < 0.05). Changes in fat deposition were associated with decreased postprandial mRNA adiponectin levels in peripheral adipose tissue and lower insulin sensitivity index values from a frequently sampled insulin-assisted intravenous glucose tolerance test in patients fed a CHO-rich diet compared with a MUFA-rich diet (ANOVA P < 0.05). CONCLUSIONS An isocaloric MUFA-rich diet prevents central fat redistribution and the postprandial decrease in peripheral adiponectin gene expression and insulin resistance induced by a CHO-rich diet in insulin-resistant subjects.

Abstract
Ein 57-jähriger Patient mit Rheumafaktor-positiver Rheumatoider Arthritis wurde uns wegen plötzlich aufgetretener petechial-papulöser Hautveränderungen mit rascher Progredienz zu multiplen hämorrhagischen Bläschenbildungen mit nachfolgenden epidermalen Hautulzerationen und -nekrotisierungen an den Händen und Fingerkuppen, den unteren Extremitäten und am Gesäss sowie einer ausgeprägten Mundaphthose zugewiesen. Fünf Tage zuvor war die zweite Gabe einer neubegonnenen low-dose-Methotrexattherapie (15 mg i.m.) zur Basisbehandlung der RA erfolgt. Der Patient befand sich insgesamt in einem vergleichsweise guten Allgemeinzustand. Im Labor zeigten sich stark erhöhte Entzündungsparameter. Wir beurteilten die Situation initial am ehesten als Methotrexat-induzierte toxische epidermale Nekrolyse. Das Methotrexat wurde sofort gestoppt und eine symptomatische perorale Therapie mit Prednison (initial Prednisonstoss 1 mg/kg KG/d über sechs Tage) durchgeführt. Im weiteren Verlauf kam es unter ausschleichender Prednisondosis bis zum Austritt (Prednison 20 mg/d) aus stationärer Behandlung zu einer kompletten Normalisierung der Entzündungszeichen im Blut. Im Verlauf der folgenden zwei Monate zeigte sich schliesslich eine fast völlige Abheilung ad integrum der genannten Hautläsionen/-defekte. Der Patient ist im Follow-up weiterhin beschwerdefrei. Die Hautdefekte sind komplett abgeheilt. Eine inzwischen begonnene antientzündliche Basistherapie mit Arava® wird vom Patienten bis anhin komplikationslos und gut vertragen.

Abstract
BACKGROUND Behçet's disease (BD) shares clinical features with well-recognised autoinflammatory disorders. In addition, mutations in genes for familial Mediterranean fever and tumour necrosis factor receptor-associated periodic syndrome have been reported to have increased in patients with BD. PATIENTS AND METHODS DNA samples from 97 patients with BD and 51 matched healthy controls were analysed for the mevalonate kinase (MVK), cold-induced autoinflammatory syndrome 1 (CIAS1) and proline/serine/threonine phosphatase-interacting protein 1 (PSTPIP1) genes, responsible for mevalonate kinase deficiency (MKD), cryopyrin associated periodic syndromes (CAPS) and pyogenic sterile arthritis, pyoderma gangrenosum and acne (PAPA) syndrome, respectively. Over 90% of known mutations were screened using restriction fragment length polymorphism analysis and/or sequencing. RESULTS Two patients had paired mutations in the MVK gene (genotypes V377I/V377I and V377I/S135L) and displayed typical features of BD and MKD. Another was heterozygotic for the V377I genotype. The V198M mutation in the CIAS1 gene was identified in one patient with typical BD but no symptoms of CAPS. No mutations were identified in the control group. PSTPIP1 analysis revealed a new exon 10 insertion variant (c.741+33_741+34insGT) in 2 of 97 patients and in 1 of 51 controls (p>0.05), indicating that it is a polymorphism rather than a true mutation. DISCUSSION This study could not demonstrate any significant increases in MVK, CIAS1 or PSTPIP1 mutations in patients with BD as compared with controls.

Abstract
In rainbow trout (Oncorhynchus mykiss), at least three CXC chemokines and eighteen CC chemokine sequences have been discovered in the past years, although no studies concerning their bioactivity have been performed yet. We have studied the expression of five different CC chemokines that cluster into the group of inducible chemokines (CK5A, CK5B, CK6, CK7A and CK7B) in trout injected with a plasmid coding for the glycoprotein G gene (pMCV1.4-G) of viral haemorrhagic septicemia virus (VHSV). In a previous work, we had demonstrated that a plasmid coding for the CXC chemokine interleukin 8 (IL-8, pIL8+) when co-administered with pMCV1.4-G was able to modulate the expression of induced pro-inflammatory cytokines, therefore, we have also studied the expression of these inducible CC chemokines in fish injected with pMCV1.4-G in the presence of pIL8+, study that will also help establish the relations among the different chemokine groups. All chemokines were induced in the head kidney of fish injected with the DNA vaccine, and the co-administration of pIL8+ together with the vaccine modulated the expression of all CC chemokines studied. In this sense, expression of the inducible CC chemokines was also studied in trout head kidney leucocytes treated with supernatants from EPC cells transfected with pIL8+. In this case, all CC chemokines studied except for CK5B were significantly induced by rainbow trout IL-8.

Abstract
BACKGROUND Radio-frequency ablation (RFA) is an increasingly used treatment modality for hepatocellular carcinoma (HCC) in patients awaiting liver transplantation (OLTX). The current study evaluates the effectiveness of RFA in this setting based on evaluation of total cell death in explanted native livers. DESIGN We evaluated 36 tumors from 35 patients with RFA-treated HCC who underwent OLTX at our center between 1998 and 2002. Native livers from OLTX were extensively sampled for histologic evaluation. For each HCC, an estimate ratio of necrotic tumor areas was calculated based on hematoxylin and eosin (H&E) sections. In tumors with 10% or more residual viable areas, Tdt-mediated UTP nick-end labeling (TUNEL) was further performed to assess apoptosis in the morphologically 'viable' areas. A final 'tumor cell death' (TCD) ratio was recalculated for each HCC to include areas of apoptosis identified by TUNEL. RESULTS Based on H&E evaluation, 22/36 (61.1%) HCC revealed > or = 90% necrosis including 12/36 HCC (33.3%) showing no evidence of residual viable tumor. The overall median tumor necrosis was 79%. When TUNEL findings were added, 26/36 (72.2%) HCC revealed > or = 90% TCD including 14/36 HCC (38.8%) showing complete TCD (median TCD of 88.4%). None of our patients died of HCC while awaiting OLTX. Longer RFA-to-transplant time appears to be associated with a higher TCD rate (median of 154.5 days in patients with less than 90% TCD vs 326 days for patients with > or = 90% TCD; P = 0.019). There was no significant correlation between tumor grade or pre-RFA size of the tumors and TCD rate in RFA-treated HCC (P = 0.11). CONCLUSION Extensive TCD (88.4% median) can be obtained using RFA for HCC in patients awaiting OLTX. Our TUNEL findings suggest that RFA-induced cell injury could be associated with apoptosis.

Abstract
BACKGROUND In patients who underwent radical resection for gastric cancer, we investigate the relative efficacy of combined 5-fluorouracil+adriamycin or epirubicin and methotrexate with leucovorin rescue (FAMTX or FEMTX) compared with a control arm. PATIENTS AND METHODS This report is a prospective combined analysis of two randomized clinical trials conducted on patients who underwent radical resection for histologically proven adenocarcinoma of the stomach or esophago-gastric junction. Three hundred and ninety-seven untreated patients, 206 from 23 European Organization for Research and Treatment of Cancer (EORTC) institutions and 191 from 16 International Collaborative Cancer Group (ICCG) institutions, were randomized. Overall survival (OS) and disease-free survival (DFS) were estimated using the Kaplan-Meier method and the treatments were compared for these end-points by means of the log-rank test, retrospectively stratified by trial. RESULTS In a planned combined analysis of the two trials, no significant differences were found between the treatment and control arms for either DFS (hazards ratio: 0.98, P=0.87) or OS (hazards ratio: 0.98, P=0.86). The 5-year OS was 43% in the treatment arm and 44% in the control arm and the 5-year DFS was 41% and 42%, respectively. CONCLUSION Neither FAMTX nor FEMTX can be advocated as adjuvant treatment in patients who undergo resection for gastric cancer.

Abstract
OBJECTIVE To assess the influence of inducible and endothelial nitric oxide synthase (iNOS and eNOS) polymorphisms in susceptibility to rheumatoid arthritis (RA). METHODS Two hundred RA patients fulfilling the 1987 American College of Rheumatology classification criteria followed at the out-patient rheumatology clinic of the Hospital Xeral-Calde (Lugo, Spain) and 251 ethnically matched controls were studied. Patients and controls were genotyped by PCR-based techniques for a multiallelic (CCTTT)(n) repeat in the promoter region of the iNOS gene and for a T/C polymorphism at position -786 in the promoter region and a polymorphism in exon 7 (298Glu/Asp or 5557G/T) of the eNOS gene. RESULTS No significant difference in allele or genotype frequencies for either polymorphism in the eNOS gene was observed between RA patients and controls. The overall iNOS CCTTT(n) allelic or genotypic distribution did not show statistical significant differences between RA patients and controls. Interestingly, when we stratified the iNOS alleles into short (8-11) and long (12-16) repeats, significant differences were observed between RA patients and controls (P = 0.021; odds ratio = 1.37, 95% confidence interval 1.04-1.81). Of note, individuals carrying two alleles with a repeat number less than 12 (fewer than 196 base pairs) exhibited a double risk of developing RA (P = 0.005, odds ratio 2.26, 95% confidence interval 1.25-4.08). CONCLUSIONS Significant differences in the iNOS promoter polymorphism genotype frequency between northwest Spanish RA patients and controls suggest a potential role for this polymorphism in susceptibility to RA.
