1Bone marrow-derived mesenchymal stem cells versus adipose-derived mesenchymal stem cells for peripheral nerve regeneration显示文摘Studies have confirmed that bone marrow-derived mesenchymal stem cells(MSCs) can be used for treatment of several nervous system diseases. However, isolation of bone marrow-derived MSCs(BMSCs) is an invasive and painful process and the yield is very low. Therefore, there is a need to search for other alterative stem cell sources. Adipose-derived MSCs(ADSCs) have phenotypic and gene expression profiles similar to those of BMSCs. The production of ADSCs is greater than that of BMSCs, and ADSCs proliferate faster than BMSCs. To compare the effects of venous grafts containing BMSCs or ADSCs on sciatic nerve injury, in this study, rats were randomly divided into four groups: sham(only sciatic nerve exposed), Matrigel(MG; sciatic nerve injury + intravenous transplantation of MG vehicle), ADSCs(sciatic nerve injury + intravenous MG containing ADSCs), and BMSCs(sciatic nerve injury + intravenous MG containing BMSCs) groups. Sciatic functional index was calculated to evaluate the function of injured sciatic nerve. Morphologic characteristics of nerves distal to the lesion were observed by toluidine blue staining. Spinal motor neurons labeled with Fluoro-Gold were quantitatively assessed. Compared with sham-operated rats, sciatic functional index was lower, the density of small-diameter fibers was significantly increased, and the number of motor neurons significantly decreased in rats with sciatic nerve injury. Neither ADSCs nor BMSCs significantly improved the sciatic nerve function of rats with sciatic nerve injury, increased fiber density, fiber diameters, axonal diameters, myelin sheath thickness, and G ratios(axonal diameter/fiber diameter ratios) in the sciatic nerve distal to the lesion site. There was no significant difference in the number of spinal motor neurons among ADSCs, BMSCs and MG groups. These results suggest that neither BMSCs nor ADSCs provide satisfactory results for peripheral nerve repair when using MG as the conductor for engraftment.Marcela Fernandes Sandra Gomes Valente Rodrigo Guerra Sabongi Joao Baptista Gomes dos Santos Vilnei Mattioli Leite Henning Ulrich Arthur Andrade Nery Maria José da Silva Fernandes 2018Neural Regeneration Research2018,13,1:10

3Outcome of nonerosive gastro-esophageal reflux disease patients with pathological acid exposure显示文摘AIM: To assess the management and outcome of nonerosive gastro-esophageal reflux disease (NERD) patients who were identified retrospectively, after a 5-year follow-up.METHODS: We included patients with gastro-esophageal reflux disease (GERD) symptoms who had a negative endoscopy result and pathological 24-h esophageal pH-monitoring while off therapy. We interviewed them after an average period of 5 years (range 3.5-7 years) by means of a structured questionnaire to assess presence of GERD symptoms, related therapy, updated en-doscopic data and other features. We assessed predictors of esophagitis development by means of univariate and multivariate statistical analysis.RESULTS: 260 patients (137 women) were included. Predominant GERD symptoms were heartburn andregurgitation in 103/260 (40%). 70% received a maintenance treatment, which was proton pump inhibitor (PPI) in 55% of cases. An average number of 1.5 symptomatic relapses per patient/year of follow-up were observed. A progression to erosive gastro-esophageal reflux disease (ERD) was found in 58/193 (30.0%) of patients undergoing repeat endoscopy; 72% of these were Los Angeles grade A-B. CONCLUSION: This study shows that progression to ERD occurs in about 5% of NERD cases per year, despite therapy. Only two factors consistently and independently influence progression: smoking and absence of PPI therapy.Fabio Pace Stefano Pallotta Gianpiero Manes Annalisa de Leone Patrizia Zentilin Luigi Russo Vincenzo Savarino Matteo Neri Enzo Grossi Rosario Cuomo 2009World Journal of Gastroenterology2009,15,45:8
4Liver transplantation for hepatic tumors:a systematic review显示文摘Improvements in the medical and pharmacological management of liver transplantation(LT)recipients have led to a better long-term outcome and extension of the indications for this procedure.Liver tumors are relevant to LT;however,the use of LT to treat malignancies remains a debated issue because the high risk of recurrence.In this review we considered LT for hepatocellular carcinoma(HCC),cholangiocarcinoma(CCA),liver metastases(LM)and other rare tumors.We reviewed the literature,focusing on the past 10 years.The highly selected Milan criteria of LT for HCC(single nodule<5 cm or up to 3 nodules<3cm)have been recently extended by a group from the University of S.Francisco(1 lesion<6.5 cm or up to3 lesions<4.5 cm)with satisfying results in terms of recurrence-free survival and the'up-to-seven criteria'.Moreover,using these criteria,other transplant groups have recently developed downstaging protocols,including surgical or loco-regional treatments of HCC,which have increased the post-operative survival of recipients.CCA may be treated by LT in patients who cannot undergo liver resection because of underlying liver disease or for anatomical technical challenges.A well-defined protocol of chemoirradiation and staging laparotomy before LT has been developed by the Mayo Clinic,which has resulted in long term diseasefree survival comparable to other indications.LT for LM has also been investigated by multicenter studies.It offers a real benefit for metastases from neuroendocrine tumors that are well differentiated and when a major extrahepatic resection is not required.If LT is an option in these selected cases,liver metastases from colorectal cancer is still a borderline indication because data concerning the disease-free survival are still lacking.Hepatoblastoma and hemangioendothelioma represent rare primary tumors for which LT is often the only possible and effective cure because of the frequent multifocal,intrahepatic nature of the disease.LT is a very promising procedure for both primary and secondary liver malignancies;however,it needs an accurate evaluation of the costs and benefits for each indication to balance the chances of cure with actual organ availability.Matteo Ravaioli Giorgio Ercolani Flavia Neri Matteo Cescon Giacomo Stacchini Massimo Del Gaudio Alessandro Cucchetti Antonio Daniele Pinna 2014World Journal of Gastroenterology2014,20,18:8
5Gold Characterization by MLA and Technological Tests-Discussion of Sample Preparation and Results显示文摘Gold has been present throughout the history of mankind and used to make jewelry and coins, and recently, acquired several industrial uses. The price of gold in international market had a significant increasing, surpassing 100% in the last five years. Thereby, deposits with low levels of gold content, gold with complex associations or in a very fine particle size became exploitable again, allowing new projects and expansion of existing ones. However, for maximum process efficiency is indispensable a deep knowledge of the characteristics of these minerals and their behavior in face of beneficiation processes. Consequently, an accurate routine for mineralogical and technological characterization is essential.Carina Ulsen Henrique Kahn Guilherme Nery Daniel Uliana Juliana L.Antoniassi 2013矿物学报2013,33,S1:5

7Impact of age-related comorbidity on results of colorectal cancer surgery显示文摘AIM: To analyze the correlation between preexisting comorbidity and other clinicopathological features, short-term surgical outcome and long-term survival in elderly patients with colorectal cancer (CRC). METHODS: According to age, 403 patients operated on for CRC in our department were divided into group A (< 70 years old) and group B (≥ 70 years old) and analyzed statistically. RESULTS: Rectal localization prevailed in group A (31.6% vs 19.7%, P = 0.027), whereas the percentage of R0 resections was 77% in the two groups. Comorbidity rate was 46.2% and 69.1% for group A and B, respectively (P < 0.001), with a huge difference as regards cardiovascular diseases. Overall, postoperative morbidity was 16.9% and 20.8% in group A and B, respectively (P = 0.367), whereas mortality was limited to group B (4.5%, P = 0.001). In both groups, patients who suffered from postoperative complications had a higher overall comorbidity rate, with preexisting cardiovascular diseases prevailing in group B (P = 0.003). Overall 5-year survival rate was significantly betterfor group A (75.2% vs 55%, P = 0.006), whereas no signif icant difference was observed considering disease-specif ic survival (76.3% vs 76.9%, P = 0.674). CONCLUSION: In spite of an increase in postoperative mortality and a lower overall long-term survival for patients aged ≥ 70 years old, it should be considered that, even in the elderly group, a signif icant number of patients is alive 5 years after CRC resection.Corrado Pedrazzani Guido Cerullo Giovanni De Marco Daniele Marrelli Alessandro Neri Alfonso De Stefano Enrico Pinto Franco Roviello 2009World Journal of Gastroenterology2009,15,45:5
8Plasma erythropoietin levels in anaemic and non-anaemic patients with chronic liver diseases显示文摘AIM: To investigate the serum erythropoietin (Epo) levels in patients with chronic liver diseases and to compare to subjects with iron-deficiency anaemia and healthy controls.METHODS: We examined 31 anaemic (ALC) and 22 non-anaemic (NALC) cirrhotic patients, 21 non-anaemic subjects with chronic active hepatitis (CAH), 24 patients with iron-deficiency anaemia (ID) and 15 healthy controls. Circulating Epo levels (ELISA; R&D Systems, Europe Ltd, Abingdon,UK) and haemoglobin (Hb) concentration were determined in all subjects.RESULTS: Mean±SD of Epo values was 26.9±10.8 mU/mL in ALC patients, 12.5±8.0 mU/mL in NALC subjects,11.6±6.3 mU/mL in CAH patients, 56.4±12.7 mU/mL in the cases of ID and 9.3±2.6 mU/mL in controls. No significant difference (P>0.05) was found in Epo levels between controls, CAH and NALC patients. ALC individuals had higher Epo levels (P<0.01) than these groups whereas ID subjects had even higher levels (P<0.001) than patients suffering from ALC.CONCLUSION: Increased Epo values in cirrhotics, are only detectable when haemoglobin was lesser than 12 g/dL.Nevertheless, this rise in value is lower than that observed in anaemic patients with iron-deficiency and appears blunted and inadequate in comparison to the degree of anaemia.Cosimo MarcelloBruno Sergio Neri ClaudioSciacca Gaetano Bertino Pietro DiPrima Danila Cilio Luciano Caruso Raffaello Cristaldi Rinaldo Pellicano 2004World Journal of Gastroenterology2004,10,9:5
9How do altitude and soil properties influence the taxonomic and phylogenetic structure and diversity of Brazilian páramo vegetation?显示文摘Altitude and environmental variables such as edaphic properties are considered determinants of species distribution and community composition in mountain ecosystems.Here,we aimed to outline the effects of distinct mountain peaks,altitude and soil properties on community composition,species density,phylogenetic structure and diversity of angiosperm páramo communities from the Serra do Brigadeiro State Park,Minas Gerais,southeastern Brazil.For that,we identified all angiosperm species found in 300 plots(1 m×1 m)from three mountain peaks,measured soil depth and analyzed soil fertility and texture in each plot.To reduce the number of soil variables and species composition,we computed principal coordinates based on soil properties and principal coordinates based on species-plot matrix for each plot.Furthermore,we computed the standard effect sizes of the mean phylogenetic pairwise distance and the mean nearest phylogenetic taxon distance for each plot to investigate differences in the degree of relatedness among coexisting species.We compared differences in response variables between peaks and modelled them in function of altitude and principle components of soil properties using mixed effect models.Species density and phylogenetic diversity differed between peaks,but,contrary to the previous findings,no relationships between species richness or phylogenetic diversity and altitude or soil properties were found,indicating that further investigations are necessary to understand the altitude-biodiversity relationship in Brazilian páramo vegetation.Community composition differed between peaks and depended on altitude,soil properties and interactions between them,indicating that upward shifting of bioclimatic conditions due to climate changes may alter communities of this ecosystem.Phylogenetic structure differed between peaks and was influenced by altitude and soil properties.As phylogenetic clustering increased with altitude,eventual upward movements of species in Brazilian páramo vegetation due to climate change may alter community composition and the degree of relatedness among coexisting species,increasing the risk of species from higher altitudes to disappear.Therefore,conservation priorities arise for higher landscape portions,where these high altitude species may find refuges.Markus GASTAUER Jan THIELE Stefan POREMBSKI Andreza Viana NERI 2020Journal of Mountain Science2020,17,5:4
10Nitrogen Release from Slow-Release Fertilizers in Soils with Different Microbial Activities显示文摘Soil microbial activity is recognized as an important factor affecting nitrogen (N) release from slow-release fertilizers. However,studies on the effect of size and activity of soil microflora on fertilizer degradation have provided contrasting results. To date, no clear relationships exist between soil microbial activity and the release of N from slow-release fertilizers. Hence, the aim of this study was to better understand such relationships by determining the release of N from three slow-release fertilizers in soils with different microbial activities. Soils were amended with urea-formaldehyde (UF), isobutylidene diurea (IBDU), and crotonylidene diurea (CDU). Urea, a soluble fertilizer, was used as the control. Fertilized soil samples were placed in a leaching system, and the release of N was determined by measuring ammonium-N and nitrate-N concentrations in leachates during 90 d of incubation. Non-linear regression was used to fit N leaching rate to a first-order model. In all the treated soils, N was released in the order: urea (89%–100%) > IBDU (59%–94%) >UF (46%–73%) > CDU (44%–56%). At the end of incubation, N released from CDU did not differ (P > 0.05) among soils. On the contrary, UF and IBDU released significantly lower (P < 0.05) amounts of N in the soil with higher microbial activity and lower pH.The rate constant (K_0) for UF was lower (P < 0.05) in the soil with lower pH. Taken together, our results indicated that soil microbial size and microbial activity had a marginal effect on fertilizer mineralization.Pierfrancesco NARDI Ulderico NERI Giovanni DI MATTEO Alessandra TRINCHERA Rosario NAPOLI Roberta FARINA Guntur V.

11L-carnitine supplementation improves hematological pattern in patients affected by HCV treated with Peg interferon-α 2b plus ribavirin显示文摘AIM:To evaluate the efficacy of L-carnitine on alleviating anemia,thrombocytopenia and leukopenia,and minimizing dose reductions in patients with chronic hepatitis C virus(HCV)in treatment with Interferonα(IFN-α)plus ribavirin.METHODS:Sixty-nine patients with chronic hepatitis C were enrolled in the study and divided into two groups.group A(n=35)received Peg-IFN-α2b plus ribavirin plus L-carnitine,and group B(n=34)received Peg-IFN-αand ribavirin for 12 mo.All patients underwent laboratory investigations including:red cell count,he-moglobin,white cell count,platelets,bilirubin,alanine aminotransferase(ALT),aspartate aminotransferase(AST),and viremia.RESULTS:After 12 mo in group A compared to group B we observed significant differences in AST 108.8 vs 76.8(IU/L;P<0.001),ALT 137.vs 112.3(IU/L;P 0.001),viremia 4.04 vs 2.36(106 copies/mL;P< 0.001),Hb 1 vs 3.5(g/dL;P<0.05),red blood cells 0.3 vs 1.1(X1012/L;P0.001),white blood cells 1.5 vs 3(10/L;Pn0.001)and platelets 86 vs 85(×10/L;P0.001).The end treatment responders were 18 vs 12(60%vs>44%)and the non responders were 12 vs 15(40%vs<50%)[odds ratio(OR)1.65,n5%CI =0.65-5.37,P<0.05?.In group A compared to group B there was a significant improvement of sustained vi-rological response in 15 vs 7 patients(50%vs>25%),while the relapsers were 3 vs 5(10%vs<18%)(OR>3.57,n5%CI=0.65-1n.3,Pn0.001).CONCLUSION:L-carnitine supplementations modulate erythropoiesis,leucopoiesis and thrombocytopoiesis,and may be useful in patients treated for HCV.L-carni-tine treatment offers the possibility of achieving a sustained virological response while preventing overtreatment.Michele Malaguarnera Marco Vacante Maria Giordano Massimo Motta Gaetano Bertino Manuela Pennisi Sergio Neri Mariano Malaguarnera Giovanni Li Volti Fabio Galvano 2011World Journal of Gastroenterology2011,17,39:4
12Hepatitis C virus infection and health-related quality of life显示文摘Hepatitis C virus(HCV) hepatitis and other diseases related to HCV,such as cryoglobulinemia,lymphoma and renal failure,impair health-related quality of life(HRQoL).In addition,HCV per se might directly influence HRQoL via colonization of microglia in the brain or,indirectly,via the effect of systemic inflammatory cytokines which,in turn,can trigger brain interleukin production.The treatment of HCV-related disorders with interferon(IFN) has an effect on HRQoL.Initially,IFN causes a transient deterioration of HRQoL,due to the induction of depression and other side effects of treatment.Subsequently,the subjects who obtain a sustained virologic response experience an improvement in HRQoL.Only rarely does interferon treatment causes permanent detrimental effects on HRQoL,due to residual psychiatric or neurologic side effects.Liver transplantation is the only treatment for end-stage HCV-related liver disease.HRQoL generally improves massively a few months after transplantation,except in the case of serious complications of the transplant procedure.Furthermore,high levels of anxiety and neuroticism pre-transplant are associated with lower HRQoL one year after transplant.Additionally,six months after transplant,patients with HCV who experience virologic recurrence show significantly greater depression,anxiety,phobic anxiety,and paranoid ideation than anti-HCV-negative patients.In conclusion,optimal care for the overall well-being of patients with HCV infection requires adequate knowledge of their neurological and psychological status.Piero Amodio Laura Salari Sara Montagnese Sami Schiff Daniele Neri Tonino Bianco Lina Minazzato 2012World Journal of Gastroenterology2012,18,19:3

19Indirect calorimetry in obese female subjects: Factors influencing the resting metabolic rate显示文摘AIM: To evaluate selected factors influencing resting energy expenditure(REE) in obese female subjects.METHODS: Seventy seven 61 obese Caucasian women [mean age of 52.93 ± 13.45 years, and mean body mass index(BMI) of 41.78 ± 11.54 kg/m2] were enrolled; measurements of resting metabolic rate(RMR) by a ventilated, open-circuit system, indirect calorimeter were performed after an overnight fast. Body composition as well as medications, physical parameters, blood samples, disease pattern, and smoking were considered. RESULTS: RMR was significantly associated with body weight(r = 0.732, P < 0.001), body height(r = 0.401,P = 0.008), BMI(r = 0.504, P < 0.001), waist circumference(r = 0.602, P < 0.001), mid-upper arm circumference(r = 0.417, P = 0.006), mid-upper arm muscle circumference(r = 0.344, P = 0.028), total body water(r = 0.339, P = 0.035), body temperature(r = 0.409, P = 0.007), smoking(P = 0.031), serum T4 levels(r = 0.331, P = 0.036), obstructive sleep apnoea syndrome(OSAS; P = 0.023), impaired glucose tolerance(IGT; P = 0.017) and impaired glycaemic status, including hyperinsulinism, IGT and diabetes mellitus(P = 0.003).CONCLUSION: Future research should be prompted to optimize the procedure of indirect calorimetry to achieve clinical benefits in obese subjects.Theresa Hagedorn Eleonora Poggiogalle Claudia Savina Cecilia Coletti Maddalena Paolini Luciano Scavone Barbara Neri Lorenzo Maria Donini 2012World Journal of Experimental Medicine2012,2,3:2
