1Response evaluation of chemotherapy in metastatic colorectal cancer by contrast enhanced ultrasound显示文摘AIM:To evaluate whether contrast enhanced ultrasound(CEUS) might also be used for response prediction and early response evaluation in patients receiving bevacizumab based chemotherapy for metastasized colorectal cancer.METHODS:Thirty consecutive patients with non primary resectable liver metastases from colorectal cancer underwent CEUS before treatment(CEUS date 1) and before the second(CEUS date 2) and fourth(CEUS date 3) cycle of bevacizumab based chemotherapy.Three parameters [PEAK,Time to peak(TTP) and RISE RATE]were correlated with radiological response.RESULTS:For neoadjuvant purpose a reduction of tumour mass was required to assume clinical response.Based on these response criteria there was a significant(P < 0.001) correlation in TTP between metastases of responders(9.08 s) and non-responders(14.76 s) archived on CEUS date 1.By calculating a standardized quotient(metastases divided by normal liver tissue) we were able to define a cut off,predicting response with a sensitivity of 92.3 % and a specificity of 100 %.To reflect a palliative intention only those patients with progressive disease were classified as non-responders.In this stetting TTP was also significantly(P < 0.01) different between responders and non-responders.In contrast,Peak and Rise rate did not show any significant difference between responder and non-responder.CONCLUSION:CEUS might serve as a surrogate marker to predict treatment response in patients with metastasized colorectal cancer who receive antiangiogenic therapy.Ramin Schirin-Sokhan Ron Winograd Christoph Roderburg Jhenee Bubenzer Nicole Cabral do ó Dorothee Guggenberger Hartmut Hecker Christian Trautwein Jens J W Tischendorf 2012World Journal of Gastroenterology2012,18,6:16
2Assessment of vascular invasion in gastric cancer: A comparative study显示文摘AIM: To evaluate and compare detection of lymphatic and blood vessel invasion (LVI and BVI) by hematox-ylin-eosin (HE) and immunohistochemistry (IHC) in gastric cancer specimens, and to correlate with lymph node status. METHODS: IHC using D2-40 (a lymphatic endothelial marker) and CD34 (a pan-endothelial marker) was performed to study LVI and BVI in surgical specimens froma consecutive series of 95 primary gastric cancer cases. The results of the IHC study were compared with the detection by HE using McNemar test and kappa index. The morphologic features of the tumors and the presence of LVI and BVI were related to the presence of lymph node metastasis. A χ2 test was performed to obtain associations between LVI and BVI and other prognostic factors for gastric cancer. RESULTS: The detection rate of LVI was considerably higher than that of BVI. The IHC study identified eight false-positive cases and 13 false-negative cases for LVI, and 24 false-positive cases and 10 false-negative cases for BVI. The average Kappa value determined was moderate for LVI (k=0.50) and low for BVI (k=0.20). Both LVI and BVI were statistically associated with the presence of lymph node metastasis (HE: P=0.001, P=0.013, and IHC: P=0.001, P=0.019). The mor-phologic features associated with LVI were location of the tumor in the distal third of the stomach (P=0.039), Borrmann's macroscopic type (P=0.001), organ inva-sion (P=0.03) and the depth of tumor invasion (P=0.001). The presence of BVI was related only to the depth of tumor invasion (P=0.003). CONCLUSION: The immunohistochemical identification of lymphatic and blood vessels is useful for increasing the accuracy of the diagnosis of vessel invasion and for predicting lymph node metastasis.Letícia Trivellato Gresta Ismael Alves Rodrigues-Júnior Lúcia Porto Fonseca de Castro Geovanni Dantas Cassali Mnica Maria Demas lva-res Cabral 2013World Journal of Gastroenterology2013,19,24:8

4Characterization of soil fauna under the influence of mercury atmospheric deposition in Atlantic Forest, Rio de Janeiro, Brazil显示文摘The increasing levels of mercury(Hg) found in the atmosphere arising from anthropogenic sources, have been the object of great concern in the past two decades in industrialized countries. Brazil is the seventh country with the highest rate of mercury in the atmosphere.The major input of Hg to ecosystems is through atmospheric deposition(wet and dry), being transported in the atmosphere over large distances. The forest biomes are of strong importance in the atmosphere/soil cycling of elemental Hg through foliar uptake and subsequent transference to the soil through litter, playing an important role as sink of this element. Soil microarthropods are keys to understanding the soil ecosystem, and for such purpose were characterized by the soil fauna of two Units of Forest Conservation of the state of the Rio de Janeiro, inwhich one of the areas suffer quite interference from petrochemicals and industrial anthropogenic activities and other area almost exempts of these perturbations. The results showed that soil and litter of the Atlantic Forest in Brazil tend to stock high mercury concentrations, which could affect the abundance and richness of soil fauna, endangering its biodiversity and thereby the functioning of ecosystems.Andressa Cristhy Buch Maria Elizabeth Fernandes Correia Daniel Cabral Teixeira Emmanoel Vieira Silva-Filho 2015Journal of Environmental Sciences2015,27,6:3
5Potential role of Limosilactobacillus fermentum as a probiotic with anti-diabetic properties: A review显示文摘Oxidative stress,inflammation,and gut microbiota impairments have been implicated in the development and maintenance of diabetes mellitus.Strategies capable of recovering the community of commensal gut microbiota and controlling diabetes mellitus have increased in recent years.Some lactobacilli strains have an antioxidant and anti-inflammatory system capable of protecting against oxidative stress,inflammation,and diabetes mellitus.Experimental studies and some clinical trials have demonstrated that Limosilactobacillus fermentum strains can beneficially modulate the host antioxidant and anti-inflammatory system,resulting in the amelioration of glucose homeostasis in diabetic conditions.This review presents and discusses the currently available studies on the identification of Limosilactobacillus fermentum strains with anti-diabetic properties,their sources,range of dosage,and the intervention time in experiments with animals and clinical trials.This review strives to serve as a relevant and well-cataloged reference of Limosilactobacillus fermentum strains capable of inducing anti-diabetic effects and promoting health benefits.Diego Cabral Lacerda Paulo César Trindade da Costa Paula Brielle Pontes Lucas Alves Carneiro dos Santos JoséPatrocínio Ribeiro Cruz Neto Cristiane Cosmo Silva Luis Vanessa Polyana de Sousa Brito JoséLuiz de Brito Alves 2022World Journal of Diabetes2022,13,9:3
6Larvicidal activities of hydro-ethanolic extracts of three Cameroonian medicinal plants against Aedes albopictus显示文摘Objective: To investigate the larvicidal activity of Syzygium guineense(Myrtaceae)(S. guineense), Monodora myristica and Zanthoxylum heitzii(Rutaceae)(Z. heitzii) extracts against Aedes albopictus(Ae. albopictus).Methods: The larvicidal activity of the hydro-ethanolic extracts from these plant species was assessed at three different concentrations(50, 100 and 200 mg/L) on first-instar of Ae. albopictus larvae in comparison with untreated controls. Mortality rate was recorded daily for a period of 12 days. The values of LC_(50) and lethal time killing 50% of the tested individuals(LT_(50)) were calculated using the log-probit analysis.Results: The root extract of S. guineense exhibited the best activity with 100% mortality after 8 days of treatment at 200 mg/L, followed by the fruit extract of Z. heitzii with83.33% mortality at the same concentration. Nonetheless, larvae were most susceptible to the fruit extract of Z. heitzii both in terms of LC_(50)(39.89 mg/L) and LT_(50)(145.68 h). A statistically significant difference between the control and the group treated at 200 mg/L was noticed in all the extracts.Conclusions: The present study shows that the hydro-ethanolic extracts of S. guineense,Monodora myristica and Z. heitzii tested have significant larvicidal activity. These preliminary results are of great interest and some of these plant species can be proposed for the formulation of new bioinsecticides to control Ae. albopictus populations.Tankeu Nzufo Francine Biapa Nya Prosper Cabral Pieme Constant Anatole Moukette Moukette Bruno Nanfack Pauline Ngogang Yonkeu Jeanne 2016Asian Pacific Journal of Tropical Biomedicine2016,6,11:2
