This process involves a series of orderly steps including components of the vasculature, platelets (primary haemostasis) and coagulation proteins

(secondary haemostasis), leading to the formation of a platelet plug and culminating in the formation of a stable fibrin clot. Congenital defects of platelets or plasma proteins involved in this process generally lead to lifelong bleeding disorders [1,2]. Haemophilia A and haemophilia selleck inhibitor B, both of which are X-chromosome linked and caused by a defect of coagulation factor (F) VIII or FIX, are more common [3–5]. Other bleeding disorders, with the exception of von Willebrand disease, are relatively rare (Table 1). Molecular genetic diagnosis of bleeding disorders remains an important and integral part of the evaluation of this condition.

There are two different approaches to the genetic evaluation of bleeding disorders: analysis of single nucleotide polymorphism (SNP) or microsatellite short tandem repeat (STR) markers in the gene of interest to track the defective chromosome in the family (linkage analysis), or identification of the disease-causing mutation in the patient’s coagulation factor gene (direct mutation detection) [6,7]. Before embarking on genetic testing, it is imperative Selleck Alpelisib that detailed clinical evaluation and conclusive phenotypic diagnosis be available. In this review, the authors trace the evolution and the applications of molecular genetics in bleeding disorders. The current protocols available for genetic testing is a convergence of intense research and development of genetic tools over the last 50 years (Prof. Tuddenham) and which has benefited immensely enough from the availability of a vast repertoire of bio-informatics and molecular biology tools over the last decade or so (Dr. Anne Goodeve). With a steady growth in the number of

laboratories that offer genetic testing for disorders of haemostasis worldwide, the availability of rigorous external quality assessment programmes (Dr. David Perry) and reference materials to run such programmes (Dr. Elaine Gray) have helped to maintain the quality and integrity of reporting data during the genetic testing of various bleeding disorders. Since 1962 is the starting point of this short history, one asks oneself, ‘What was it like back then?’ Personally I had been accepted into Westminster Medical School and was studying mathematics during what is now called ‘the gap year’. Although I was in London, the famous 60s passed me by almost completely. Genetics as a science was still in its formal era as defined by Haldane in the Croonian lecture of 1948.

These data suggest that CCl4-induced liver fibrosis might be inhibited in SMP30 KO mice due to inhibition of the nuclear translocation of p-Smad2/3 and a lower level of ROS and lipid peroxidation as compared with WT mice. To GSK126 determine if activated HSCs express SMP30 in the fibrotic liver, we performed immunohistochemistry using

SMP30 antibody and α-SMA antibody on serial liver sections. As shown in Fig. 4A, nonparenchymal cells exhibited no expression of SMP30 (Fig. 4A, a, arrowheads and b, arrows), whereas hepatocytes revealed obvious nuclear and cytoplasmic expression of SMP30 (Fig. 4A, a and b, asterisk). In normal livers of WT mice, the quiescent HSCs containing lipid droplets in their cytoplasm also showed depletion of SMP30 (Fig. 4A, a, arrowhead). To confirm more clearly whether HSCs from WT mice express SMP30, we performed immunocytochemistry and RT-PCR analysis using isolated HSCs. The

isolated HSCs were cultured for 6 days in serum-containing medium and learn more the SMP30 messenger RNA (mRNA) expression was determined on day 0, day 3, and day 5. As expected, HSCs from the WT mice and SMP30 KO mice revealed obvious SMP30 deficiency (Fig. 4B,C). Immunocytochemistry also showed well-matched results with the RT-PCR analysis confirming HSCs from the WT mice and the SMP30 KO mice do not express SMP30 (Fig. 4B). These data demonstrated that SMP30 is not involved directly in the activation of HSCs, suggesting the possibility of the participation of other up-regulated or down-regulated factors affecting hepatocytes and HSCs in the liver of the SMP30 KO mice. As expected, the SMP30 KO mice liver tissue showed significantly enhanced PPAR-γ expression levels and mRNA levels compared with those of the WT mice (Fig. 5A,B). In order to compare the expression level selleck inhibitor of PPAR-γ, p-Smad2/3, α-SMA, and the activation degree of SMP30 KO HSC with WT HSC, HSCs were isolated and cultured in serum containing medium for 7 days. It was found that WT HSCs were activated faster compared with SMP30 KO HSCs until day 5 (Fig. 5C). Moreover, both the α-SMA expression and the p-Smad2/3 nuclear expression were much stronger in WT HSCs

than in SMP30 KO HSCs (Fig. 5C). Additionally, it was observed that SMP30 KO HSCs contained a greater number of cytoplasmic lipid droplets compared with WT HSCs at the same time (Fig. 5D), which was well-matched with the HSC hypertrophy morphology in vivo in our previous unpublished data. For the sake of clarity, we used an RT-PCR analysis. On day 0, day 3, and day 5 the α-SMA mRNA expression levels of SMP30 KO HSCs were significantly inhibited compared with those of WT mice HSCs (Fig. 5E). The PPAR-γ expression levels showed time-dependent decreases in both WT mice HSCs and SMP30 KO HSCs. However, SMP30 KO HSCs revealed much greater PPAR-γ expression levels compared with WT HSCs at the same time (Fig. 5E). We observed that PPAR-γ negatively down-regulated α-SMA mRNA expression levels.

The final category involves traumatic bowel erosions. When the entire colon is affected, toxic megacolon may result. Patients with NE present with fever in most cases, right lower quadrant pain in 13% to 92%

of cases,39,52–54 diarrhea in 38% to 94%,52,53 nausea and vomiting in 27% to 75%.49,53,54 They may be tachycardic, tachypneic, and diaphoretic Bortezomib cost with signs of dehydration and sepsis. According to a retrospective analysis, malabsorption of D-xylose, as a measure of the functional integrity of the mucosa, is an independent predictor of NE as it correlates with the risk of invasive infection independent of the degree of myelosuppression.55 It also correlates with the type of induction therapy. Gross bleeding occurs in 36% to 65% of patients35,52 due to the combination of mucosal damage and thrombocytopenia. Septicemia may occur in 73% of patients with about half of these cases being polymicrobial.49 Occasionally, NE may present with sepsis alone, without any GI symptoms.56 Physical findings include a right-lower-quadrant mass or fullness,38 abdominal distension in 50% to 58% of patients,53,54 and diffuse tenderness in 63%.53 The absolute Palbociclib neutrophil count is uniformly low with a median duration before diagnosis of 32 days57 and a median neutrophil count of 200.36 Gram-negative bacteria are the most frequently

indentified pathogens.36,48 There may be an increase in total bilirubin, primarily the direct fraction, of unclear significance.38 Plain films are abnormal in 50% to 100% of cases39,58 with a lack of bowel gas in the right lower quadrant and distension of the small bowel. Also seen may be a right lower quadrant soft tissue mass representing fluid-filled, atonic, dilated cecum and ascending colon,59 occasionally progressing out to bowel obstruction.40,60 Ultrasound is a modality often preferred by pediatricians since

it is convenient, inexpensive, avoids ionizing radiation, and does not involve contrast.37 It will show homogeneous echogenic thickening of the bowel wall or the target sign in 79% of evaluated patients.36,61,62 The degree of bowel wall thickening detected by ultrasonography correlated with the need for surgery, the duration of diarrhea,36 and the outcome of patients: 60% of patients with mural thickness greater than 10 mm die from this complication.63 CT scan, the modality preferred by many physicians, may show non-specific ileus, diffuse bowel wall thickening, phlegmon, extraluminal collections, mesenteric stranding, pericecal inflammation, or pneumatosis intestinalis.64–66 The thickened cecum is usually isodense compared to surrounding normal bowel but may have hypodense areas presumably from edema, hemorrhage, or necrosis.

332, P < .0001, OR 1.931 [CI 1.448–2.575]). Considering only young populations with actual overweight-obesity, defined by weight/height measurement and by BMI criteria, perceived overweight-obesity is not significantly associated with headache (χ2 1.472, P = .225, OR 1.551 [CI 0.827–2.907]). Young populations with actual normal weight, defined by weight/height measurement and by BMI criteria, perceived overweight-obesity is significantly associated

with headache (χ2 18.710, P < .0001, OR 2.181 [CI 1.537–3.097]). Alvelestat concentration According to our results, headache does not have a straightforward association with overweight-obesity in youngsters when considering the objective measurement criterion. We observed a greater association of an individual perception of overweight-obesity with headache. As Chai and colleagues appropriately address in their review,[1] it is possible that epidemiological reports[7] could be biased by the actual definition of overweight-obesity, namely by the self-reported and not actually measured weight and height. Since headache is reported with a greater frequency check details in younger population groups with an erroneous perception of excessive weight, the challenge could be that prevention programs designed to address specific behaviors that can affect the development of obesity should take into account the behavioral correlates of body weight perception. This demands the planning

of a more articulated approach when targeting subgroups, Inositol monophosphatase 1 considering also the possible effects of both environment and habits. “
“The neuropathic

origin of a case of unilateral burning mouth syndrome, previously diagnosed as psychogenic, was ascertained by intra-oral mucosa biopsy, which showed a severe sensory fibers damage, probably caused by maxillary anesthetic block and dental surgery. “
“Although the drug topiramate initially was developed for the treatment of epilepsy and received its first US Food and Drug Administration (FDA) approval for that purpose, it subsequently was shown to be effective for the prevention of migraine headaches and is FDA approved for that indication as well. Migraine and epilepsy share a considerable number of biologic and clinical features, and it follows that certain of the newer anti-epileptic drugs are effective for the prevention of migraine attacks as well as seizures. Precisely how topiramate prevents migraine is unclear, but generally speaking, it appears to reduce the genetically derived brain hyperexcitability that provokes migraine attacks in susceptible individuals. While the clinical trials for migraine prevention that earned topiramate its FDA approval involved patients with episodic migraine (ie, less than 15 headache days per month), 1 large, randomized, placebo-controlled study indicated that topiramate may be effective for patients with chronic migraine as well (ie, 15 or more headache days per month).

Roberts – Board Membership: Jannsen, Roche, Gilead, BMS The following people have nothing to disclose: Lingling Han Purpose:HCV infection

is the most common indication for liver transplantation(LT). HCV recurrence after LT is universal, leading to premature graft failure in 30-50% of patients(pts). Inter-feron-based HCV therapies are limited by toxicity and poor efficacy. ABT-450 is an HCV NS3/4A protease inhibitor(dosed with ritonavir, ABT-450/r) identified by AbbVie HSP inhibitor and Enanta. Ombitasvir is an NS5A inhibitor; dasabuvir is an NS5B RNA polymerase inhibitor. We examined safety and efficacy of ABT-450/r/ombitasvir and dasabuvir plus

ribavirin(3D+RBV) in non-cirrhotic LT recipients with recurrent HCV genotype(GT) 1 infection. Methods:In this ongoing open-label phase 2 trial, pts received 24 weeks of co-formulated ABT-450/r/ombitas-vir(150mg/100mg/25mg QD) and dasabuvir(250mg BID) plus RBV(dosed at investigator discretion). Eligibility criteria included LT≥12 months before screening, HCV treatment-naive since LT, and screening biopsy Metavir score≤F2. Due to interactions between calcineurin inhibitors(CNIs) and study regimen, modified CNI dosing was advised(tacroli-mus: 0.5mg once weekly or 0.2mg every 3 days; cyclospo-rine: 1/5 the daily pre-study dose once daily). RVR, EOTR, SVR4, SVR12, and SVR24 Apoptosis Compound Library mw rates MycoClean Mycoplasma Removal Kit are reported. Updated SVR

rates will be presented. Results:All 34 enrolled pts achieved RVR and EOTR(Table). SVR4, SVR12, and SVR24 rates are 97.1%(33/34), 97.0%(32/33), and 93.3%(14/15). No pt had breakthrough on treatment; 1 relapsed. Advised lower CNI dosing resulted in stable CNI levels. The most common treatment-emergent adverse events(AEs) were fatigue(50.0%) and headache(44.1%). One pt discontinued treatment after week 18 due to AEs(moderate rash, memory impairment, anxiety); this pt achieved SVR12. Five pts with grade 2(N=4) or grade 3(N=1) hemoglobin decreases received erythropoietin at investigator discretion. No pt was transfused or had an episode of acute rejection. Conclusions:LT recipients with recurrent HCV GT1 infection achieved high SVR rates with the interfer-on-free 3D+RBV regimen. The regimen was generally well-tolerated and drug-drug interactions were manageable. Disclosures: Parvez S.

28 Purified immunoglobulin G (IgG) from rat anti-CLDN1 serum were obtained by MAbTrap kit (GE Healthcare). To analyze cross-reactivity of antibodies with other members of the CLDN family, 293T cells were transfected to express AcGFP tagged CLDN1, 4, 6, 7, 9, 11, 15, and 17 or chimeric CLDN1/7 (described by Evans et al.9) and 48 hours later stained with rat anti-CLDN1 antibodies and Alexa-633

coupled anti-rat immunoglobulin (Invitrogen). Polyclonal rat anti–SR-BI or CD81 antibodies were obtained by genetic immunization as described.26 R-phycoerythrin–conjugated and Cy5-conjugated anti-rat IgG were obtained from Jackson ImmunoResearch Laboratories, mouse IgG was obtained from Caltag, and mouse anti-CD81 (JS-81) was obtained from BD Biosciences. Living Huh7.5.1 cells were incubated with preimmune or anti-CLDN1 serum (1/50) and a Cy5-conjugated anti-rat secondary antibody (1/300). Polarized selleck chemicals Caco-2 cells, as described by Mee et al.,23 were fixed in 3% paraformaldehyde, permeabilized with

saponin, and stained with polyclonal anti-CLDN1 (1/50) or control serum. Following staining, cells were fixed, mounted, and observed using a Leica TCS SP2 CLSM (for Huh7.5.1) or a Zeiss Cell Axio Observer Z1 microscope (for Caco-2). To determine Carfilzomib the functionality of TJs and whether they restrict the paracellular diffusion of solutes from the bile-canalicular (BC) lumen to the basolateral medium (barrier function), HepG2 cells were treated with either control (PBS), rat anti-CLDN1, rat control serum, or interferon-γ and incubated with 5 mM 5-chloromethylfluorescein diacetate

(CMFDA) (Invitrogen) at 37°C for 10 minutes to allow internalization and translocation to BC lumen by MRP2. After washing with PBS, the capacity of BC lumens to retain CMFDA was analyzed as described.18 Cell culture–derived HCV (HCVcc) (Luc-Jc1 or Jc1) were generated as described.6, 26, 29 For infection experiments, Huh7.5.1 cells were preincubated in the presence or absence of antibodies for 1 hour at 37°C and infected at 37°C for 4 hours with HCVcc. Forty-eight hours later HCV infection was analyzed in cell lysates by quantification of luciferase activity or viral RNA.6, 26, 29, 30 Kinetic studies in the presence of antibodies or inhibitors were performed as described.6, 26, 29, 30 Infection of 293T/CLDN1 or Huh7.5.1 cells with murine leukemia virus–based HCV pseudoparticles Progesterone (HCVpp) in kinetic assays was performed as described.5, 6 Primary hepatocytes were infected with HIV-based HCVpp expressing envelope glycoproteins of strains HCV-J (genotype 1b), JFH-1 (genotype 2a), UKN3A.1.28 (genotype 3a), and UKN4.21.16 (genotype 4). One day following hepatocyte isolation and plating, hepatocytes were washed with PBS and preincubated with rat anti-CLDN1 or control serum (1/50) for 1 hour at 37°C in William’s E medium. Then, HCVpp were added for 3 hours at 37°C. Following infection, the supernatant was removed and replaced by fresh William’s E medium.

Finally, cells were washed and incubated in complete culture medium at 37°C for 45 hours. Infections were scored by measuring luciferase activity. Huh-7 cells were infected check details with purified

HCVcc in 24-well plates for 1 hour at 4°C in the presence of either DMSO, or 50 μM of EGCG, or 500 μg/mL of porcine intestinal heparin. Cells were washed with PBS, and total RNA was extracted using the NucleoSpin RNA II kit (Macherey-Nagel, Düren, Germany), according to the manufacturer’s instructions. HCV RNA was quantified by quantitative real-time reverse-transcription polymerase chain reaction (qRT-PCR) assay as described previously. 27 Before analyzing the potential antiviral effect of EGCG on HCV, we first determined the toxicity of EGCG selleck kinase inhibitor on Huh-7 cells (Fig. 1A). Although some toxicity began to be observed at 100 μM, a concentration of 50 μM was shown to have no toxic effect, even after 72

hours. The half lethal dose was between 150 and 175 μM in Huh-7 cells, depending on the exposition time. To test the effect of EGCG on the HCV life cycle, the molecule was added to the medium during HCVcc infection. Interestingly, more than 1 log10 decrease of HCVcc infectious titers was observed in cells treated with 50 μM of EGCG (Fig. 1B). To confirm our results on HCV, we used a recombinant HCV expressing the Renilla luciferase (i.e., JFH1-Luc) to infect cells in the presence of increasing concentrations of EGCG. A dose-dependent decrease of JFH1-Luc infection was observed (Fig. 1C). The half-maximal inhibitory concentration (IC50) was estimated to approximately 5 μM, and the 90% inhibitory concentration (IC90) was close to 50 μM. Thus, the therapeutic index of EGCG is approximately 30. Together, these results show that EGCG has an antiviral activity against HCV. Other catechins extracted from green tea include (+)-catechin, EC, ECG, and EGC (Fig. 1D). The toxicity

of each catechin was determined individually (Supporting Fig. 1). Then, each catechin was tested for its antiviral activity. (+)-Catechin and EC did not display any anti-HCV activity (Fig. 1E). In contrast, both ECG and EGC exhibited an inhibition of HCV infection of approximately 40% and 80%, respectively. Furthermore, we confirmed the antiviral Rucaparib chemical structure activity of EGCG by using EGCG provided by another manufacturer. To test whether EGCG would be a general viral inhibitor, experiments were performed with two other members of the Flaviviridae family (BVDV and YFV) and another unrelated virus (SINV) (Fig. 2A). HSV-1 was used as a positive control, because EGCG has an antiviral activity against this virus 12 (Fig. 2B). In contrast to HCV and HSV-1, EGCG treatment at 50 μM has no antiviral effect on BVDV, YFV, and SINV, indicating that the effect of EGCG could not be generalized to the Flaviviridae family in our experimental conditions.

Conversely, no lacZ expression is found in CD31+ SECs (Fig. 4E). Although several groups including us suggested a possible contribution of the liver mesothelium to HSCs during liver development,11-13, 15 a definitive validation of this

hypothesis has not been made by rigorous genetic-based lineage-tracing methods. To directly test this notion, we used tamoxifen-inducible Wt1CreERT2 mice for tracing Wt1+ MC/SubMCs. To quantify the contribution of Wt1+ MC/SubMCs to Wt1− HSCs and PMCs, we injected tamoxifen at E10.5 for labeling the Wt1+ MC/SubMCs as lacZ-expressing cells and serially examined the livers 1, 2, and 3 days after the treatment (Fig. 5A). We predicted that if lacZ+ Wt1+ MC/SubMCs in E11.5 livers migrate inward and differentiate into HSCs and PMCs, tamoxifen injection would result in lacZ expression in Wt1− HSCs Selumetinib purchase and PMCs in E12.5 and E13.5 livers (Fig. 5A). One day after tamoxifen injection, lacZ expression is indeed found in MC/SubMCs in the E11.5 livers (Fig. 5B). The expression of lacZ is rarely found in HSCs near the liver surface (Fig. 5B). Expression of Wt1 is seen in lacZ+ MC/SubMCs, but not in lacZ+ HSCs inside the liver (Fig. 5B, arrowhead). From E12.5 livers, desmin+ lacZ+ HSCs and PMCs are readily found inside the livers (Fig. 5C,D). Importantly, these lacZ+ HSCs and PMCs do not express Wt1 (Fig. 5C,D, arrowheads).

We also confirmed the absence of CreERT2 protein in HSCs and PMCs by immunostaining of E11.5

to E13.5 livers for the estrogen receptor (ER) epitope of CreERT2 CP-690550 chemical structure (Fig. 5B-D).22 CreERT2 protein was SB-3CT restricted to MCs and some SubMCs. These results are considered definitive evidence for inward migration of the Wt1+ MC/SubMCs to give rise to HSCs and PMCs during liver morphogenesis. To assess the extent of the contribution of Wt1+ MC/SubMCs to the genesis of HSCs and PMCs, we quantified the lacZ+ HSCs and PMCs inside the liver (Fig. 6A, arrowheads). The number of lacZ+ cells inside the livers was 2.8 cells/mm2 (ML) and 7.1 cells/mm2 (LL) at E11.5, and increased to 26.4 cells/mm2 (ML) and 36.1 cells/mm2 (LL) at E12.5 and 39.5 cells/mm2 (ML) and 39.0 cells/mm2 (LL) at E13.5 (Fig. 6B), demonstrating that Wt1+ MC/SubMCs have migrated inward from the liver surface during the developmental period from E10.5 to E13.5. Costaining of lacZ and desmin reveals that 6.4% (ML) and 4.7% (LL) of desmin+ cells (including both HSCs and PMCs) are positive for lacZ in the E11.5 livers (Fig. 6C,D). Then the percentage of the lacZ+/desmin+ cells increases to 15.0% (ML) and 18.3% (LL) in E12.5 livers (Fig. 6D). Based on these data, we estimate that ≈8.6% (ML) and 13.6% (LL) of HSCs and PMCs are generated from the Wt1+ MC/SubMCs labeled with lacZ during 1 day between E11.5 to E12.5 stages. No further increase in the percentage of lacZ+/desmin+ cells is noted between E12.5 and E13.5. One day after tamoxifen injection, 17.4% ± 3.1% (ML) and 8.0% ± 1.

between HVPG change and decrease in the heart rate (p = 0.87) or decrease in mean blood pressure (p = 0.38). Non-signifficant adverse reactions were observed in 13 patients (19%), dose reduction was necessary in 4 patients. No serious adverse event was observed.

inappropriate activation of lymphocytes and macrophages. Guidelines for the diagnosis of HLH require the presence of 5 out of 8 findings of fever, splenomegaly, cytopenia, hypertriglyceridemia or hypofibrinogenemia, hemophagocytosis in bone marrow, spleen or lymph nodes, low or absent natural killer cell activity, and elevated serum ferritin and soluble CD25. The full clinical picture of HLH is quite characteristic, but the initial presentation is non-specific and misleading. Liver involvement is not a diagnostic criterion for HLH, but as we have observed, patients with HLH almost always have evidence of liver inflammation. Methods: A previously healthy 49-year-old man was admitted to hepatology department with confusion of the past 2-week history of fever and liver dysfunction. As the disease not progressed, findings of hepatosplenomegaly, cytopenias, hypertriglyceridemia, hypofibrinogenemia, and hematophages

in bone marrow appeared gradually. Results: And finally the case met all 8 diagnostic criteria of HLH-2004. Prednisone was used as the basic therapy for him, and his condition was improved remarkably after 16-day hospitalization. Conclusion: HLH is a hematologic disease, but not all HLH patients come to hematologic department at the beginning of the progress. As HLH is a complex syndrome which infects many other systems, doctors of other specialty should also be aware of the syndrome. Key Word(s): 1.

This MG-132 order study showed that the area under the receiver operating characteristic curve for the total CK-18 prediction of a liver fibrosis stage ≥ F2 was 0.73, which is similar to the values reported for various assays based on multiple putative fibrosis biomarkers.9 This proves that a single good biomarker of liver epithelial

death (total CK-18) provides a fairly robust readout of liver fibrosis, which is a complex injury response presumably captured by the other assays. This suggests that an active liver injury (often subclinical) is the main force perpetuating liver fibrosis in most individuals and provides a reason for optimism because it supports the dynamic nature of fibrogenesis/fibrinolysis and the inherent reversibility of liver fibrosis. Like more complex assays, the total CK-18

ELISA reliably differentiates advanced fibrosis from no fibrosis, but it is less discriminating at lower fibrosis stages; this reflects the dynamic nature of fibrosis and the fact that no available assay captures both sides of the fibrosis equation. Total CK-18 assays measure the predominant liver fibrosis stimulus (i.e., liver epithelial cell death), whereas other assays largely reflect Akt inhibitor various aspects of the resultant wound-healing response. The use of both stimulus and response assays might provide complementary/additive information that could perfect the noninvasive staging of fibrosis. In other words, combining an assessment of the strength of the fibrosis stimulus (CK-18) with an estimate of the intensity of the fibrogenic response (fibrosis markers or elastography) might permit individuals with given levels of liver cell death to be stratified into groups of hyporesponders, normoresponders, and hyperresponders with respect to wound healing. Additional power might be obtained by

the serial acquisition of such information from given individuals. Further research is needed to test and refine these concepts. Success offers exciting opportunities for personalizing liver disease management and facilitating the discovery of effective antifibrotic therapies. “
“Background and Aim: Endoscopic forceps biopsy (EFB) as the primary histological ADP ribosylation factor diagnosis of gastric epithelial neoplasia (GEN) is debated in the era of endoscopic resection (ER). Our aim was to investigate the diagnostic reliability of EFB in patients with GEN compared to ER specimens as the reference standard for the final diagnosis in a large consecutive series. Methods: This was a cross-sectional retrospective study at a tertiary-referral center. A total of 354 consecutive patients with 397 GENs underwent ER (endoscopic mucosal resection or endoscopic submucosal dissection).
