| 1 | Acute calculous cholecystitis: Review of current best practices显示文摘Acute calculous cholecystitis(ACC) is the most frequent complication of cholelithiasis and represents one-third of all surgical emergency hospital admissions, many aspects of the disease are still a matter of debate. Knowledge of the current evidence may allow the surgical team to develop practical bedside decision-making strategies, aiming at a less demanding procedure and lower frequency of complications. In this regard, recommendations on the diagnosis supported by specific criteria and severity scores are being implemented, to prioritize patients eligible for urgency surgery. Laparoscopic cholecystectomy is the best treatment for ACC and the procedure should ideally be performed within 72h. Early surgery is associated with better results in comparison to delayed surgery. In addition, when to suspect associated common bile duct stones and how to treat them when found are still debated. The antimicrobial agents are indicated for high-risk patients and especially in the presence of gallbladder necrosis. The use of broad-spectrum antibiotics and in some cases with antifungal agents is related to better prognosis. Moreover, an emerging strategy of not converting to open, a difficult laparoscopic cholecystectomy and performing a subtotal cholecystectomy is recommended by adept surgical teams. Some authors support the use of percutaneous cholecystostomy as an alternative emergency treatment for acute Cholecystitis for patients with severe comorbidities. | Carlos Augusto Gomes Cleber Soares Junior Salomone Di Saveiro Massimo Sartelli Michel Denis Kelly Camila Couto Gomes Felipe Couto Gomes Lívia Dornellas Correa Camila Brandao Alves Samuel de Fádel Guimaraes | 2017 | World Journal of Gastrointestinal Surgery2017,9,5: | 18 |
| 2 | Multiple myeloma mesenchymal stromal cells: Contribution to myeloma bone disease and therapeutics显示文摘Multiple myeloma is a hematological malignancy inwhich clonal plasma cells proliferate and accumulate within the bone marrow. The presence of osteolytic le-sions due to increased osteoclast(OC) activity and sup-pressed osteoblast(OB) function is characteristic of the disease. The bone marrow mesenchymal stromal cells(MSCs) play a critical role in multiple myeloma patho-physiology, greatly promoting the growth, survival, drug resistance and migration of myeloma cells. Here, we specifically discuss on the relative contribution of MSCs to the pathophysiology of osteolytic lesions in light of the current knowledge of the biology of my-eloma bone disease(MBD), together with the reported genomic, functional and gene expression differences between MSCs derived from myeloma patients(pMSCs) and their healthy counterparts(dMSCs). Being MSCs the progenitors of OBs, pMSCs primarily contribute to the pathogenesis of MBD because of their reduced osteogenic potential consequence of multiple OB inhibi-tory factors and direct interactions with myeloma cells in the bone marrow. Importantly, pMSCs also readily contribute to MBD by promoting OC formation and ac-tivity at various levels(i.e., increasing RANKL to OPG expression, augmenting secretion of activin A, uncou-pling ephrinB2-EphB4 signaling, and through augment-ed production of Wnt5a), thus further contributing to OB/OC uncoupling in osteolytic lesions. In this review, we also look over main signaling pathways involved in the osteogenic differentiation of MSCs and/or OB activity, highlighting amenable therapeutic targets; in parallel, the reported activity of bone-anabolic agents(at preclinical or clinical stage) targeting those signaling pathways is commented. | Antonio Garcia-Gomez Fermin Sanchez-Guijo M Consuelo del Caizo Jesus F San Miguel Mercedes Garayoa | 2014 | World Journal of Stem Cells2014,6,3: | 5 |
| 3 | 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 |
| 4 | Effect of Nd3+doping on structure,microstructure,lattice distortion and electronic properties of TiO_2 nanoparticles显示文摘Doped and undoped TiCh nanoparticles were prepared by Stober method and thermally treated at 600 ℃.The effect of Nd^(3+) ion on the structure and micro structure of anatase-phase TiCh nanocrystals was studied by Rietveld refinement method using X-ray powder diffraction data.Bond lengths,bond angles,and edges distances were analyzed.The phase formation was confirmed by high-resolution transmission electron microscopy.The adjustment of Ti-0 bond length induced by the addition of Nd^(3+) ions,reduced the octahedral distortion and altered the octahedral array in the anatase-phase TiCh nanocrystal.The changes of structure and microstructure were mainly observed for TiCh nanoparticles doped with 0.1 at.%of Nd^(3+) ions and attributed to the cationic substitution of Ti^(4+) ions which promoted changes in the density of states and gap band of TiCh.The dopant insertion resulted in a better structural stability of the nanocrystals that enhanced their charge transference and photocatalytic efficiency. | Balter Trujillo-Navarrete María del Pilar Haro-Vázquez Rosa María Félix-Navarro Francisco Paraguay-Delgado Henry Alvarez-Huerta Sergio Pérez-Sicairos Edgar Alonso Reynoso-Soto | 2017 | Journal of Rare Earths2017,35,3: | 2 |
| 5 | Cloning of first abc transporter encoding gene from Trichoderma spp. and its expression during stress and mycoparasitism显示文摘Trichoderma in its natural environment competes for nutrient uptake and is required to protect itself from adverse natural toxic compounds, such as those produced by plants and other microbes in the soil community, or synthetic toxic compounds released human activity. One of the most important metabolic pathways for drug resistance and substrate uptake, both in prokaryotes and eukaryotes, is ATP dependent. The role of ABC transporter proteins in the biology of Trichoderma is still not known. We present the cloning of the first four ABC transporter genes (TABC1, TABC2, TABC3, TABC4 ) in Trichoderma, and in particular T. atroviride P1, and the characterization of TABC2 The complete sequence of this gene is 6535 bp, which includes a promoter of 1624 bp, a terminator of 642 bp and a coding region of 4264 bp. The promoter contains many of the potential transcription factor binding sites found in the 5’ upstream region of the ech42 gene of T. atroviride P1. These included: heat shock factors (HSF), a nitrogen-regulating factor (Nit-2), a stress-response element (STRE), a GCR1 elements, and a Cre BP1 motif. Northern analysis and RT-PCR demonstrated that TABC2 is highly expressed when Trichoderma is subjected to nitrogen starvation, grown in the presence of culture filtrates of Botrytis cinerea, Rhizoctonia solani, and Pythium ultimum, or when N-acetylglucosamine is added to the substrate. TABC2 appears to be co-regulated with some CWDE-encoding genes, suggesting that this is the first ABC transporter encoding gene involved in mycoparasitic events. It’s role in the interaction of Trichoderma with fungal hosts or plants is being investigated by targeted gene disruption and overexpression. | Lanzuise S Ruocco M Scala V Catapano L Woo S Ciliento R Ferraioli S Soriente I Vinale F Scala F Del Sorbo G Lorito M | 2004 | 浙江大学学报(农业与生命科学版)2004,30,4: | 2 |
