1Effects of Saccharomycesboulardiion fecal short-chain fatty acids and microflora in patients on long-term total enteral nutrition显示文摘AIM: To assess the effects of Sb on fecal flora and shortchain fatty acids (SCFA) in patients on long-term TEN.METHODS: Ten patients (3 females, 7 males, 59±5.5 years),on TEN for a median of 13 mo (1-125), and 15 healthy volunteers (4 females, 11 males, 32±2.0 years) received Sb (0.5 g bid PO) for 6 d. Two stool samples were taken before, on the last 2 d and 9-10 d after treatment, for SCFA measurement and for culture and bacterial identification.Values (mean±SE) were compared using sign tests and ANOVA.RESULTS: Fecal butyrate levels were lower in patients(10.1±2.9 mmol/kg) than in controls (19.2±3.9, P= 0.02).Treatment with Sb increased total fecal SCFA levels in patients (150.2±27.2 vs 107.5±18.2 mmol/kg, P = 0.02)but not in controls (129.0±28.6 vs 113.0±15.2 mmol/kg,NS). At the end of treatment with Sb, patients had higher fecal butyrate (16.0±4.4 vs 10.1 [2.9] mmol/kg, P = 0.004).Total SCFAs remained high 9 d after treatment was discontinued. Before the treatment, the anaerobe to aerobe ratio was lower in patients compared to controls (2.4±2.3 vs69.8±1.8, P = 0.003). There were no significant changes in the fecal flora of TEN patients.CONCLUSION: Sb-induced increase of fecal SCFA concentrations (especially butyrate) may explain the preventive effects of this yeast on TEN-induced diarrhea.Stéphane M Schneider Fernand Girard-Pipau Jér(o|^)me Filippi Xavier Hébuterne Dominique Moyse Gustavo Calle Hinojosa Anne Pompei Patrick Rampal 2005World Journal of Gastroenterology2005,11,39:26

7Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5
8Interplay between post-translational cyclooxygenase-2 modifications and the metabolic and proteomic profile in a colorectal cancer cohort显示文摘BACKGROUND Colorectal cancer(CRC) is the second most common cause of cancer death worldwide. It is broadly described that cyclooxygenase-2(COX-2) is mainly overexpressed in CRC but less is known regarding post-translational modifications of this enzyme that may regulate its activity, intracellular localization and stability. Since metabolic and proteomic profile analysis is essential for cancer prognosis and diagnosis, our hypothesis is that the analysis of correlations between these specific parameters and COX-2 state in tumors of a high number of CRC patients could be useful for the understanding of the basis of this cancer in humans.AIM To analyze COX-2 regulation in colorectal cancer and to perform a detailed analysis of their metabolic and proteomic profile.METHODS Biopsies from both healthy and pathological colorectal tissues were taken under informed consent from patients during standard colonoscopy procedure in the University Hospital of Bellvitge(Barcelona, Spain) and Germans Trias i Pujol University Hospital(Campus Can Ruti)(Barcelona, Spain). Western blot analysis was used to determine COX-2 levels. Deglycosylation assays were performed in both cells and tumor samples incubating each sample with peptide N-glycosidase F(PNGase F). Prostaglandin E2(PGE2) levels were determined using a specific ELISA. 1 H high resolution magic angle spinning(HRMAS) analysis was performed using a Bruker AVIII 500 MHz spectrometer and proteomic analysis was performed in a nano-liquid chromatography-tandem mass spectrometer(nano LC-MS/MS) using a QExactive HF orbitrap MS.RESULTS Our data show that COX-2 has a differential expression profile in tumor tissue of CRC patients vs the adjacent non-tumor area, which correspond to a glycosylated and less active state of the protein. This fact was associated to a lesser PGE2 production in tumors. These results were corroborated in vitro performing deglycosylation assays in HT29 cell line where COX-2 protein profile was modified after PNGase F incubation, showing higher PGE2 levels. Moreover,HRMAS analysis indicated that tumor tissue has altered metabolic features vs non-tumor counterparts, presenting increased levels of certain metabolites such as taurine and phosphocholine and lower levels of lactate. In proteomic experiments, we detected an enlarged number of proteins in tumors that are mainly implicated in basic biological functions like mitochondrial activity,DNA/RNA processing, vesicular trafficking, metabolism, cytoskeleton and splicing.CONCLUSION In our colorectal cancer cohort, tumor tissue presents a differential COX-2 expression pattern with lower enzymatic activity that can be related to an altered metabolic and proteomic profile.Patricia Prieto Rafael I Jaén Daniel Calle María Gómez-Serrano Estefanía Nú?ez María Fernández-Velasco Paloma Martín-Sanz Sergio Alonso Jesús Vázquez Sebastián Cerdán Miguel ángel Peinado Lisardo Boscá 2019World Journal of Gastroenterology2019,25,4:4
9Multiple-population QTL mapping of maturity and fruit-quality traits reveals LG4 region as a breeding target in sweet cherry(Prunus avium L.)显示文摘Sweet cherry maturity date and fruit quality are relevant traits for its marketability,transport,and consumer acceptance.In this work,sweet cherry fruit development time,maturity date,and commercial fruit-quality traits(size,weight,firmness,soluble solid content,and titratable acidity)were investigated to improve the knowledge of their genetic control,and to identify alleles of breeding interest.Six sweet cherry populations segregating for these traits were used for QTL analyses.These populations descend from cross-and self-pollinations of local Spanish sweet cherries‘Ambrunés’and‘Cristobalina’,and breed cultivars(‘Brooks’,‘Lambert’,or‘Vic’).The six populations(n=411),previously genotyped with RosBREED Cherry 6 K SNP array,were phenotyped for 2 years.QTL analyses were conducted using a multifamily approach implemented by FlexQTL™.Fruit development time,soluble solid content,and titratable acidity QTLs are first reported in sweet cherry in this work.Significant QTLs were detected for all the traits.Eighteen were more stable as they were detected for 2 years.Of these,nine are first reported in this work.The major QTLs for fruit development time,maturity date,firmness,and soluble solid content were identified on the same narrow region of linkage group 4.These traits also showed significant positive correlation(long fruit development time associated with late maturity,high firmness,and high SSC).NAC transcription factor genes identified on this LG4 region may be candidate genes for the regulation of these traits in sweet cherry,as previously described in syntenic regions of other Rosaceae species.Haplotypes of breeding interest on this LG4 genomic region were identified and will be useful for sweet cherry breeding from this and related plant material.Alejandro Calle Ana Wünsch 2020Horticulture Research2020,7,1:3

14Endoscopic ultrasound-guided through-the-needle microforceps biopsy and needle-based confocal laser-endomicroscopy increase detection of potentially malignant pancreatic cystic lesions:A single-center study显示文摘BACKGROUND Currently,there is insufficient data about the accuracy in the diagnosing of pancreatic cystic lesions(PCLs),especially with novel endoscopic techniques such as with direct intracystic micro-forceps biopsy(mFB)and needle-based confocal laser-endomicroscopy(nCLE).AIM To compare the accuracy of endoscopic ultrasound(EUS)and associated techniques for the detection of potentially malignant PCLs:EUS-guided fine needle aspiration(EUS-FNA),contrast-enhanced EUS(CE-EUS),EUS-guided fiberoptic probe cystoscopy(cystoscopy),mFB,and nCLE.METHODS This was a single-center,retrospective study.We identified patients who had undergone EUS,with or without additional diagnostic techniques,and had been diagnosed with PCLs.We determined agreement among malignancy after 24-mo follow-up findings with detection of potentially malignant PCLs via the EUSguided techniques and/or EUS-guided biopsy when available(EUS malignancy detection).RESULTS A total of 129 patients were included, with EUS performed alone in 47/129. In 82/129 patients,EUS procedures were performed with additional EUS-FNA (21/82), CE-EUS (20/82), cystoscopy(27/82), mFB (36/82), nCLE (44/82). Agreement between EUS malignancy detection and the 24-mo follow-up findings was higher when associated with additional diagnostic techniques thanEUS alone [62/82 (75.6%) vs 8/47 (17%);OR 4.35, 95%CI: 2.70-7.37;P < 0.001]. The highestmalignancy detection accuracy was reached when nCLE and direct intracystic mFB were bothperformed, with a sensitivity, specificity, positive predictive value, negative predictive value andobserved agreement of 100%, 89.4%, 77.8%, 100% and 92.3%, respectively (P < 0.001 comparedwith EUS-alone).CONCLUSIONThe combined use of EUS-guided mFB and nCLE improves detection of potentially malignantPCLs compared with EUS-alone, EUS-FNA, CE-EUS or cystoscopy.Carlos Robles-Medranda Juan I Olmos Miguel Puga-Tejada Roberto Oleas Jorge Baquerizo-Burgos Martha Arevalo-Mora Raquel Del Valle Zavala Joao Autran Nebel Daniel Calle Loffredo Hannah Pitanga-Lukashok 2022World Journal of Gastrointestinal Endoscopy2022,14,3:2
