| 1 | Influence of flooding and vegetation on carbon,nitrogen,and phosphorus dynamics in the pore water of a Spartina alterniflora salt marsh显示文摘Four sites were selected in a salt marsh in the Bah' a Blanca Estuary (Argentina):(1) low marsh (flooded by the tide twice daily) vegetated by S.alterniflora;(2) non-vegetated low marsh;(3) high marsh (flooded only in spring tides) vegetated by S.alterniflora;(4) non-vegetated high marsh.The pH and Eh were measured in sediments,while dissolved nutrients (ammonium,nitrate,nitrite and phosphate) and particulate organic matter (POM) were determined in pore water.pH (6.2-8.7) was only affected by vegetation in low areas.Eh (from-300 to 250 mV) was lower at low sites than at high ones;in the latter,the values were higher in the non-vegetated sediments.The POM concentration was greater in the high marsh than in the low marsh,with no effect of vegetation.Ammonium was the most abundant nitrogen nutrient species in pore water,except in the non-vegetated high marsh where nitrate concentration was higher.All nitrogen nutrients were affected by both flooding and vegetation.Phosphate was always present in pore water at all sites throughout the year and its concentration varied within narrow limits,with no effect of flooding and greater values always at non-vegetated sites.Our results showed that the variability of the pore water composition within the marsh is greater than the temporal variation,meaning that both tidal flooding and vegetation are important in the dynamics of nutrients and organic matter in the sediment pore water. | Vanesa L.Negrin Carla V.Spetter Raúl O.Asteasuain Gerardo M.E.Perillo Jorge E.Marcovecchio | 2011 | Journal of Environmental Sciences2011，23，2： | 11 |
| 2 | Gallstone ileus,clinical presentation,diagnostic and treatment approach显示文摘Gallstone ileus is a mechanical intestinal obstruction due to gallstone impaction within the gastrointestinal tract. Less than 1% of cases of intestinal obstruction are derived from this etiology. The symptoms and signs of gallstone ileus are mostly nonspecific. This entity has been observed with a higher frequency among the elderly, the majority of which have concomitant medical illness. Cardiovascular, pulmonary, and metabolic diseases should be considered as they may affect the prognosis. Surgical relief of gastrointestinal obstruction remains the mainstay of operative treatment. The current surgical procedures are:(1) simple enterolithotomy;(2) enterolithotomy, cholecystectomy and fistula closure(one-stage procedure); and(3) enterolithotomy with cholecystectomy performed later(two-stage procedure). Bowel resection is necessary in certain cases after enterolithotomy is performed. Large prospective laparoscopic and endoscopic trials are expected. | carlos m nuno-guzmán maría eugenia marín-contreras mauricio figueroa-sánchez jorge l corona | 2016 | World Journal of Gastrointestinal Surgery2016，8，1： | 11 |
| 3 | Tumor infiltrating lymphocytes in triple negative breast cancer receiving neoadjuvant chemotherapy显示文摘AIM To determine influence of neoadjuvant-chemotherapy(NAC) over tumor-infiltrating-lymphocytes(TIL) intriple-negative-breast-cancer(TNBC).METHODS TILs were evaluated in 98 TNBC cases who came to Instituto Nacional de Enfermedades Neoplasicas from 2005 to 2010. Immunohistochemistry staining for CD3, CD4, CD8 and FOXP3 was performed in tissue microarrays(TMA) sections. Evaluation of H/E in full-face and immunohistochemistry in TMA sections was performed in pre and post-NAC samples. STATA software was used and P value < 0.05 was considered statistically significant. RESULTS Higher TIL evaluated in full-face sections from pre-NAC tumors was associated to pathologic-complete-response(pCR)(P = 0.0251) and outcome(P = 0.0334). TIL evaluated in TMA sections showed low level of agreement with full-face sections(ICC = 0.017-0.20) and was not associated to pCR or outcome. TIL in post-NAC samples were not associated to response or outcome. PostNAC lesions with pC R had similar TIL levels than those without pCR(P = 0.6331). NAC produced a TIL decrease in full-face sections(P < 0.0001). Percentage of TIL subpopulations was correlated with their absolute counts. Higher counts of CD3, CD4, CD8 and FOXP3 in pre-NAC samples had longer disease-free-survival(DFS). Higher counts of CD3 in pre-NAC samples had longer overallsurvival. Higher ratio of CD8/CD4 counts in pre-NAC was associated with pCR. Higher ratio of CD4/FOXP3 counts in pre-NAC was associated with longer DFS. Higher counts of CD4 in post-NAC samples were associated with pCR.CONCLUSION TIL in pre-NAC full-face sections in TNBC are correlated to longer survival. TIL in full-face differ from TMA sections, absolute count and percentage analysis of TIL subpopulation closely related. | Carlos A Castaneda Elizabeth Mittendorf Sandro Casavilca Yun Wu Miluska Castillo Patricia Arboleda Teresa Nunez Henry Guerra Carlos Barrionuevo Ketty Dolores-Cerna Carolina Belmar-Lopez Julio Abugattas Gabriela Calderon Miguel De La Cruz Manuel Cotrina Jorge Dunstan Henry L Gomez Tatiana Vidaurre | 2016 | World Journal of Clinical Oncology2016，7，5： | 6 |
| 4 | Surgical options for correction of refractive error following cataract surgery显示文摘Refractive errors are frequently found following cataract surgery and refractive lens exchange.Accurate biometric analysis,selection and calculation of the adequate intraocular lens(IOL)and modern techniques for cataract surgery all contribute to achieving the goal of cataract surgery as a refractive procedure with no refractive error.However,in spite of all these advances,residual refractive error still occasionally occurs after cataract surgery and laser in situ keratomileusis(LASIK)can be considered the most accurate method for its correction.Lens-based procedures,such as IOL exchange or piggyback lens implantation are also possible alternatives especially in cases with extreme ametropia,corneal abnormalities,or in situations where excimer laser is unavailable.In our review,we have found that piggyback IOL is safer and more accurate than IOL exchange.Our aim is to provide a review of the recent literature regarding target refraction and residual refractive error in cataract surgery. | Ahmed A Abdelghany Jorge L Alio | 2014 | Eye and Vision2014，1，1： | 6 |
| 5 | Physical activity in primary and secondary prevention of cardiovascular disease:Overview updated显示文摘Although the observed progress in the cardiovascular disease treatment, the incidence of new and recurrent coronary artery disease remains elevated and constitutes the leading cause of death in the developed countries. Three-quarters of deaths due to cardiovascular diseases could be prevented with adequate changes in lifestyle, including increased daily physical activity. New evidence confirms that there is an inverse dose-response relationship between physical activity and cardiovascular disease and mortality risk. However, participation in moderate to vigorous physical activity may not fully attenuate the independent effect of sedentary activities on increased risk for cardiovascular diseases. Physical activity also plays an important role in secondary prevention of cardiovascular diseases by reducing the impact of the disease, slowing its progress and preventing recurrence. Nonetheless, most of eligible cardiovascular patients still do not benefit from secondary prevention/cardiac rehabilitation programs. The present review draws attention to the importance of physical activity in the primary and secondary prevention of cardiovascular diseases. It also addresses the mechanisms by which physical activity and regular exercise can improve cardiovascular health and reduce the burden of the disease. | Alberto J Alves Joao L Viana Suiane L Cavalcante Nórton L Oliveira JoséA Duarte Jorge Mota JoséOliveira Fernando Ribeiro | 2016 | World Journal of Cardiology2016，8，10： | 6 |
| 6 | Timely reperfusion for ST-segment elevation myocardial infarction:Effect of direct transfer to primary angioplasty on time delays and clinical outcomes显示文摘Primary percutaneous coronary intervention(PPCI) is the preferred reperfusion therapy for patients presenting with ST-segment elevation myocardial infarction(STEMI) when it can be performed expeditiously and by experienced operators. In spite of excellent clinical results this technique is associated with longer delays than thrombolysis and this fact may nullify the benefit of selecting this therapeutic option. Several strategies have been proposed to decrease the temporal delays to deliver PPCI. Among them,prehospital diagnosis and direct transfer to the cath lab,by-passing the emergency department of hospitals,has emerged as anattractive way of diminishing delays. The purpose of this review is to address the effect of direct transfer on time delays and clinical events of patients with STEMI treated by PPCI. | Rodrigo Estévez-Loureiro ángela López-Sainz Armo Pérez de Prado Carlos Cuellas Ramón Calvio Santos Norberto Alonso-Orcajo Jorge Salgado Fernández Jose Manuel Vázquez-Rodríguez Maria López-Benito Felipe Fernández-Vázquez | 2014 | World Journal of Cardiology2014，6，6： | 6 |
| 7 | Presbyopic correction on the cornea显示文摘Purpose:The aim of this systematic review was to synthesize and appraise the evidence of the benefits of presbyopic correction on the cornea for visual function.Summary:Comprehensive search was conducted in MEDLINE using keywords like“presbylasik”,“presbyopic refractive surgery”,“corneal pseudoaccommodation”and“corneal multifocality”.We reviewed corrected and uncorrected visual acuities for distance and near(uncorrected distance visual acuity(UDVA),uncorrected near visual acuity(UNVA),corrected distance visual acuity(CDVA),distance corrected near visual acuity(DCNVA),corrected near visual acuity(CNVA)),along with the refractive outcomes in spherical equivalent(SE)and astigmatism comparing the differences observed between preoperative myopic and hyperopic patients,as well as among techniques.Thirty-one studies met the inclusion and quality criteria.Monovision provides excellent distance and near uncorrected acuities,but with a 17%retreatment and a 5%reversal rate.Initial multifocal ablations result in 12%loss of 2 or more lines of CDVA,and a 21%retreatment rate.Laser Blended Vision provides excellent UDVA,but with a 19%retreatment rate.Initial experiences with Supracor show moderate predictability and a 22%retreatment rate.Intracor results in 9%loss of 2 or more lines of CDVA.KAMRA provides excellent UDVA,with only a 1%retreatment rate,but a 6%reversal rate.Initial experiences with PresbyMAX provided excellent UNVA and DCNVA,showing excellent predictability and a 1%reversal rate.Conclusions:The findings have implications for clinicians and policymakers in the health-care industry and emphasize the need for additional trials examining this important and widely performed clinical procedure. | Samuel Arba Mosquera Jorge L Alió | 2014 | Eye and Vision2014，1，1： | 6 |
| 8 | Short and long term fate of human AMSC subcutaneously injected in mice显示文摘AIM:To study the ability of human adipose-derived mesenchymal stem cells(AMSCs)to survive over the short and long term,their biodistribution and their biosafety in vivo in tumor-prone environments.METHODS:We subcutaneously injected human AMSCs from different human donors into immunodeficient SCID mice over both short-(2 and 4 mo)and long-(17 mo)term in young,and aged tumor-prone mice.Presence of human cells was studied by immunohistochemistry and polymerase chain reaction analysis in all organs of injected mice.RESULTS:Subcutaneously injected AMSCs did not form teratomas at any time point.They did not migrate but remained at the site of injection regardless of animal age,and did not fuse with host cells in any organ examined.AMSCs survived in vivo for at least 17 mo after injection,and differentiated into fibroblasts of the subdermic connective tissue and into mature adipocytes of fat tissue,exclusively at the site of injection.CONCLUSION:Our results support the assertion that AMSC may be safe candidates for therapy when injected subcutaneously because of their long term inability to form teratomas. | Pilar López-Iglesias Alejandro Blázquez-Martínez Jorge Fernández-Delgado Javier Regadera Manuel Nistal Maria P De Miguel | 2011 | World Journal of Stem Cells2011，3，6： | 5 |
| 9 | Clinicopathological predictors of long-term benefit in breast cancer treated with neoadjuvant chemotherapy显示文摘AIM To investigate the survival impact of clinicopathological factors, including pathological complete response(p CR) and tumor-infiltrating lymphocytes(s TIL) levels according to subtypes, in breast cancer(BC) patients who received neo-adjuvant chemotherapy(NAC).METHODS We evaluated 435 BC patients who presented and received NAC at the Instituto Nacional de Enfermedades Neoplasicas from 2003 to 2014. s TIL was analyzed as the proportion of tumor stroma occupied by lymphocytes, and was prospectively evaluated on hematoxylin and eosin-stained sections of the preN AC core biopsy. p CR was considered in the absence of infiltrating cancer cells in primary tumor and axillary lymph nodes. Analysis of statistical association between clinical pathological features, s TIL, p CR and survival were carried out using SPSSvs19.RESULTS Median age was 49 years(range 24-84 years) and the most frequent clinical stage was ⅢB(58.3%). Luminal A, Luminal B, HER2-enriched and(triple-negative) TN phenotype was found in 24.6%, 37.9%, 17.7% and 19.8%, respectively. p CR was observed in 11% and median percentage of s TIL was 40%(2%-95%) in the whole population. p CR was associated to Ct1-2(P = 0.045) and to high s TIL(P = 0.029) in the whole population. There was a slight trend towards significance for s TIL(P = 0.054) in Luminal A. s TIL was associated with grade Ⅲ(P < 0.001), no-Luminal A subtype(P < 0.001), RE-negative(P < 0.001), PgR-negative(P < 0.001), HER2-positive(P = 0.002) and p CR(P = 0.029) in the whole population. Longer disease-free survival was associated with grade Ⅰ-Ⅱ(P = 0.006), cN 0(P < 0.001), clinical stage Ⅱ(P = 0.004), ER-positive(P < 0.001), Pg R-positive(P < 0.001), luminal A(P < 0.001) and p CR(P = 0.002). Longer disease-free survival was associated with grade Ⅰ-Ⅱ in Luminal A(P < 0.001), N0-1 in Luminal A(P = 0.045) and TNBC(P = 0.01), clinical stage Ⅱ in Luminal A(P = 0.003) and TNBC(P = 0.038), and pC R in TNBC(P < 0.001). Longer overall survival was associated with grade Ⅰ-Ⅱ(P < 0.001), ER-positive(P < 0.001), PgR-positive(P < 0.001), Luminal A(P < 0.001), cN 0(P = 0.002) and p CR(P = 0.002) in the whole population. Overall survival was associated with clinical stage Ⅱ(P = 0.017) in Luminal A, older age(P = 0.042) in Luminal B, and pC R in TNBC(P = 0.005).CONCLUSION Predictive and prognostic values of clinicopathological features, like p CR and s TIL, differ depending on the evaluated molecular subtype. | Marco Galvez Carlos A Castaneda Joselyn Sanchez Miluska Castillo Lia Pamela Rebaza Gabriela Calderon Miguel De La Cruz Jose Manuel Cotrina Julio Abugattas Jorge Dunstan Henry Guerra Omar Mejia Henry L Gomez | 2018 | World Journal of Clinical Oncology2018，9，2： | 4 |

| 11 | Detection and characterization of murine colitis and carcinogenesis by molecularly targeted contrast-enhanced ultrasound显示文摘AIM To study mucosal addressin cellular adhesion molecule-1(MAd CAM-1) and vascular endothelial growth factor(VEGF)-targeted contrast enhanced ultrasound(CEUS) for the assessment of murine colitis and carcinogenesis. METHODS C57BL/6 mice were challenged with 3% dextran sodium-sulfate(DSS) for three, six or nine days to study the development of acute colitis. Ultrasound was performed with and without the addition of unspecific contrast agents. MAd CAM-1-targeted contrast agent was used to detect and quantify MAd CAM-1 expression. Inflammatory driven colorectal azoxymethane(AOM)/DSS-induced carcinogenesis was examined on day 42 and 84 using VEGF-targeted contrast agent. Highly specific tissue echogenicity was quantified using specialized software. Sonographic findings were correlated to tissue staining, western blot analysis and immunohistochemistry to quantify the degree of inflammation and stage of carcinogenesis. RESULTS Native ultrasound detected increased general bowel wall thickening that correlated with more progressed and more severe DSS-colitis(healthy mice: 0.3 mm ± 0.03 vs six days DSS: 0.5 mm ± 0.2 vs nine days DSS: 0.6 mm ± 0.2, P < 0.05). Moreover, these sonographic findings correlated well with clinical parameters such as weight loss(r2 = 0.74) and histological damage(r2 = 0.86)(P < 0.01). In acute DSS-induced murine colitis, CEUS targeted against MAd CAM-1 detected and differentiated stages of mild, moderate and severe colitis via calculation of mean pixel contrast intensity in decibel(9.6 d B ± 1.6 vs 12.9 d B ± 1.4 vs 18 d B ± 3.33, P < 0.05). Employing the AOM/DSSinduced carcinogenesis model, tumor development was monitored by CEUS targeted against VEGF and detected a significantly increased echogenicity in tumors as compared to adjacent healthy mucosa(healthy mucosa, 1.6 d B ± 1.4 vs 42 d, 18.2 d B ± 3.3 vs 84 d, 18.6 d B ± 4.9, P < 0.01). Tissue echogenicity strongly correlated with histological analysis and immunohistochemistry findings(VEGF-positive cells in 10 high power fields of healthy mucosa: 1 ± 1.2 vs 42 d after DSS start: 2.4 ± 1.6 vs 84 d after DSS start: 3.5 ± 1.3, P < 0.01). CONCLUSION Molecularly targeted CEUS is a highly specific and noninvasive imaging modality, which characterizes murine intestinal inflammation and carcinogenesis in vivo. | Markus Brückner Jan Heidemann Tobias M Nowacki Friederike Cordes Jorg Stypmann Philipp Lenz Faekah Gohar Andreas Lügering Dominik Bettenworth | 2017 | World Journal of Gastroenterology2017，23，16： | 4 |

| 13 | Clinical outcomes with a new microincisional diffractive multifocal IOL显示文摘Background:To evaluate the refractive outcomes and the optical performance as well as the quality of life in patients implanted with a new diffractive multifocal intraocular lens(IOL).Methods:Prospective,clinical study including 41 cases of patients who underwent cataract surgery and were divided in two groups:group 1,including 20 eyes implanted with the multifocal IOL SeeLens MF(Hanita Lenses,Israel);group 2,21 eyes implanted with the Acrysof SA60AT IOL.Visual acuity,defocus curve,intraocular aberrations,contrast sensitivity function and quality of life were assessed during a follow up period of 6 months.Results:Significant improvement was observed in the uncorrected distance visual acuity(UDVA)and corrected distance visual acuity(CDVA)in both groups(p<0.02).The multifocal group showed better results in terms of uncorrected near visual acuity(UNVA)and distance-corrected near visual acuity(DCNVA)(p<0.01).Comparison of both groups showed better visual acuities for the multifocal IOL group in defocus levels from-3.0 D to-1.50 D(p≤0.01).At 6 months,there was a significant reduction of the internal higher order aberrations(p≤0.04).A significant increase in scotopic contrast sensitivity was detected for 6 cycles/°spatial frequency during follow up(p=0.04),but no significant changes were observed for the rest of spatial frequencies(p≥0.06).Visual Functioning Index(VF-14)questionnaire showed that patients reported high levels of satisfaction when performing daily tasks.Conclusions:The SeeLens MF IOL is able to successfully restore distance,near and intermediate visions after cataract surgery.It also provides functional intermediate vision with optimal intraocular optical quality. | Jorge L Alió Alfredo Vega-Estrada Ana B Plaza-Puche | 2015 | Eye and Vision2015，2，1： | 3 |
| 14 | Downregulation of the Basic Peroxidase Isoenzyme from Zinnia elegans by Gibberellic Acid显示文摘Hypocotyl formation during the epigeal germination of seedlings is under strict hormonal regulation. In a 3 d old Zinnia elegans seedling system, gibberellic acid (GA3) exerts an opposite effect to that exerted by light on hypocotyl photomorphogenesis because GA3 promotes an etiolated-like growth with an inhibition of radial (secondary) growth. For this reason, the effect of GA3 on the basic peroxidase isoenzyme from Z. elegans (ZePrx), an enzyme involved in hypocotyl lignin biosynthesis, was studied. The results showed that GA3 reduces ZePrx activity, similarly to the way in which it reduces seedling secondary growth. This hormonal response is supported by the analysis of the ZePrx promoter, which contains four types of GA3-responsive cis-elements: the W Box/O2S; the Pyr Box; the GARE; and the Amy Box. Taken together, these results suggest that ZePrx is directly regulated by GA3, with this effect matching the inhibitory effect of GA on the hypocotyl secondary growth. | María Josefa López Núez-Flores Jorge Gutirrez Laura V.Gómez-Ros Esther Novo Uzal Mariana Sottomayor Alfonso Ros Barceló | 2010 | Journal of Integrative Plant Biology2010，52，2： | 3 |
| 15 | Total phenolic content,in vitro antioxidant activity and chemical composition of plant extracts from semiarid Mexican region显示文摘Objective:To determine the extraction suitable conditions of total phenolic content(TPC) by heat-reflux system,antioxidant activities and HPLC characterization of the aqueous-ethanolic extracts of Jatropha dioica(J.dioica)(Dragon's blood).Flourensia cernua(F.cernua)(Tar bush).Eucalyptus camaldulensis(E.camaldulensis)(Eucalyptus) and Turnera diffusa(T.diffusa)(Damiana).Methods:TPC was evaluated by the well-known colorimetric assay using FolinCiocalteu reagent.The antioxidant activities were assayed by three methods based on scavenging of DPPH,ABTS and by lipid oxidation inhibition.The chemical composition of the extracts obtained was subject to HPLC analysis.Results:TPC in the plant extracts ranged from 2.3 to14.12 mg gallic acid equivalents/g for J.dioica and E.camaldulensis,respectively.The plant extracts of F.cernua,E.camaldulensis and T.diffusa showed similar strong antioxidant activities on scavenging of DPPH and lipid oxidation inhibition.In contrast,J.dioica extracts had lowest potential antioxidant in three assays used.HPLC assay showed the presence of several phenolic compounds in the extracts used.Conclusions:The results obtained suggest that F.cernua,E.camaldulensis and T.diffusa are potential sources to obtain bioactive phenolic compounds with high antioxidant properties which can be used in the factories as antioxidant agents or for treatments in diseases. | Jorge E.Wong-Paz Juan C.Contreras-Esquivel Raúl Rodríguez-Herrera María L.Carrillo-Inungaray Lluvia I.López Guadalupe V.Nevárez-Moorillón Cristóbal N.Aguilar | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，2： | 3 |
| 16 | Effect of femtosecond laser-assisted lens surgery on the optic nerve head and the macula显示文摘AIM: To evaluate the effect of femtosecond laser-assisted lens surgery(FLALS;cataract surgery or refractive lens exchange) on the structure of the optic nerve head and the macula.METHODS: This prospective longitudinal study included healthy eyes undergoing FLALS. Eyes with glaucoma or any other ocular disease that could alter optical coherence tomography results were excluded. Retinal nerve fiber layer(RNFL), Bruch’s membrane opening-minimum rim width(BMO-MRW) and macular thickness(MT) were measured preoperatively, 1 and 6 mo after surgery using spectral-domain optical coherence tomography(SD-OCT). Changes between preoperative and postoperative values were evaluated.RESULTS: A total of 87 eyes of 46 patients were included in this study. Preoperative RNFL, BMO-MRW and MT in microns(μm) were 100.77±10.39, 330.31±49.99 and 276.30±33.39, respectively. Postoperative RNFL, BMO-MRW and MT were 104.74±11.55, 348.32±54.05 and 279.83±22.65 1 mo after surgery and 102.93±11.17, 343.11±53.4 and 278.90±22.19 6 mo after surgery, respectively;which equals an increase of 3.93%, 5.45% and 1.27%,respectively, 1 mo after surgery, and 2.14%, 3.87% and 0.94% 6 mo after surgery. The differences between the preoperative and the postoperative RNFL and BMO-MRW values were statistically significant(P<0.001). Regarding MT values, there were not statistically significant differences(P=0.26).CONCLUSION: Our study suggests that FLALS does not have a negative impact on the structural status of the optic nerve head in healthy eyes, assessed by SD-OCT. There is a slight increase in the values of RNFL, BMO-MRW and MT 1 mo and 6 mo after surgery. | Josefina Renones de Abajo Beatriz Estévez Jorge Jesús María González Martín Humberto Carreras Díaz Juan Francisco Loro Ferrer Alfonso Antón López | 2019 | International Journal of Ophthalmology(English edition)2019，12，6： | 2 |
| 17 | Liver fat deposition and mitochondrial dysfunction in morbid obesity:An approach combining metabolomics with liver imaging and histology显示文摘AIM: To explore the usefulness of magnetic resonance imaging(MRI) and spectroscopy(MRS) for assessment of non-alcoholic fat liver disease(NAFLD) as compared with liver histological and metabolomics findings. METHODS: Patients undergoing bariatric surgery following procedures involved in laparoscopic sleeve gastrectomy were recruited as a model of obesityinduced NAFLD in an observational, prospective, singlesite, cross-sectional study with a pre-set duration of 1 year. Relevant data were obtained prospectively and surrogates for inflammation, oxidative stress and lipid and glucose metabolism were obtained through standard laboratory measurements. To provide reliable data from MRI and MRS, novel procedures were designed to limit sampling variability and other sources of error using a 1.5T Signa HDx scanner and protocols acquired from the 3D or 2D Fat SAT FIESTA prescription manager. We used our previously described 1H NMRbased metabolomics assays. Data were obtained immediately before surgery and after a 12-mo period including histology of the liver and measurement of metabolites. Values from 1H NMR spectra obtained after surgery were omitted due to technical limitations.RESULTS: MRI data showed excellent correlation with the concentration of liver triglycerides, other hepatic lipid components and the histological assessment, w h i c h e xc l u d e d t h e p r e s e n c e o f n o n-a l c o h o l i c steatohepatitis(NASH). MRI was sufficient to follow up NAFLD in obese patients undergoing bariatric surgery and data suggest usefulness in other clinical situations. The information provided by MRS replicated that obtained by MRI using the-CH3 peak(0.9 ppm), the-CH2- peak(1.3 ppm, mostly triglyceride) and the-CH=CH- peak(2.2 ppm). No patient depicted NASH. After surgery all patients significantly decreased their body weight and steatosis was virtually absent even in patients with previous severe disease. Improvement was also observed in the serum concentrations of selected variables. The most relevant findings using metabolomics indicate increased levels of triglyceride and monounsaturated fatty acids in severe steatosis but those results were accompanied by a significant depletion of diglycerides, polyunsaturated fatty acids, glucose-6-phosphate and the ATP/AMP ratio. Combined data indicated the coordinated action on mitochondrial fat oxidation and glucose transport activity and may support the consideration of NAFLD as a likely mitochondrial disease. This concept may helpto explain the dissociation between excess lipid storage in adipose tissue and NAFLD and may direct the search for plasma biomarkers and novel therapeutic strategies. A limitation of our study is that data were obtained in a relatively low number of patients.CONCLUSION: MRI is sufficient to stage NAFLD in obese patients and to assess the improvement after bariatric surgery. Other data were superfluous for this purpose. | Nahum Calvo Raúl Beltrán-Debón Esther Rodríguez-Gallego Anna Hernández-Aguilera Maria Guirro Roger Mariné-Casadó Lidón Millá Josep M Alegret Fàtima Sabench Daniel del Castillo María Vinaixa Miguelàngel Rodríguez Xavier Correig Roberto García-álvarez Javier A Menendez Jordi Camps Jorge Joven | 2015 | World Journal of Gastroenterology2015，21，24： | 2 |
| 18 | Evaluation of biodegradable electric conductive tube-guides and mesenchymal stem cells显示文摘AIM: To study the therapeutic effect of three tubeguides with electrical conductivity associated to mesenchymal stem cells(MSCs) on neuro-muscular regeneration after neurotmesis.METHODS: Rats with 10-mm gap nerve injury were tested using polyvinyl alcohol(PVA), PVA-carbon nanotubes(CNTs) and MSCs, and PVA-polypyrrole(PPy). The regenerated nerves and tibialis anterior muscles were processed for stereological studies after 20 wk. The functional recovery was assessed serially for gait biomechanical analysis, by extensor postural thrust, sciatic functional index and static sciatic functionalindex(SSI), and by withdrawal reflex latency(WRL). In vitro studies included cytocompatibility, flow cytometry, reverse transcriptase polymerase chain reaction and karyotype analysis of the MSCs. Histopathology of lung, liver, kidneys, and regional lymph nodes ensured the biomaterials biocompatibility. RESULTS: SSI remained negative throughout and independently from treatment. Differences between treted groups in the severity of changes in WRL existed, showing a faster regeneration for PVA-CNTs-MSCs(P < 0.05). At toe-off, less acute ankle joint angles were seen for PVA-CNTs-MSCs group(P = 0.051) suggesting improved ankle muscles function during the push off phase of the gait cycle. In PVA-PPy and PVA-CNTs groups, there was a 25% and 42% increase of average fiber area and a 13% and 21% increase of the 'minimal Feret's diameter' respectively. Stereological analysis disclosed a significantly(P < 0.05) increased myelin thickness(M), ratio myelin thickness/axon diameter(M/d) and ratio axon diameter/fiber diameter(d/D; g-ratio) in PVA-CNT-MSCs group(P < 0.05). CONCLUSION: Results revealed that treatment with MSCs and PVA-CNTs tube-guides induced better nerve fiber regeneration. Functional and kinematics analysis revealed positive synergistic effects brought by MSCs and PVA-CNTs. The PVA-CNTs and PVA-PPy are promising scaffolds with electric conductive properties, bio- and cytocompatible that might prevent the secondary neurogenic muscular atrophy by improving the reestablishment of the neuro-muscular junction. | Jorge Ribeiro Tiago Pereira Ana Rita Caseiro Paulo Armada-da-Silva Isabel Pires Justina Prada Irina Amorim Sandra Amado Miguel Franca Carolina Goncalves Maria Ascensao Lopes Jose Domingos Santos Dina Morais Silva Stefano Geuna Ana Lúcia Luís Ana Colette Maurício | 2015 | World Journal of Stem Cells2015，7，6： | 2 |
