Minimally invasive esophagectomy versus open esophagectomy: A systematic review and meta-analysis.

The paradigm of the treatment of esophageal cancer has been changing with the increasing use of minimally invasive esophagectomy (MIE) in detriment of open esophagectomy (OE). We aimed to perform a meta-analysis to evaluate and compare these two techniques in terms of mortality and associated complications. The literature search was conducted in MEDLINE and U.

Transcriptomics reveals the action mechanisms and cellular targets of citrate-coated silver nanoparticles in a ubiquitous aquatic fungus.

Silver nanoparticles (AgNPs) are among the major groups of contaminants of emerging concern for aquatic ecosystems. The massive application of AgNPs relies on the antimicrobial properties of Ag, raising concerns about their potential risk to ecologically important freshwater microbes and the processes they drive. Moreover, it is still uncertain whether the effects of AgNPs are driven by the same mechanisms underlying those of Ag ions (Ag).

Proteomic responses to silver nanoparticles vary with the fungal ecotype.

Enhanced commercial application of silver nanoparticles (AgNPs) is increasing the chance of their release into aquatic environments, potentially putting non-target microorganisms at risk. Impacts of AgNPs and Ag on two fungal ecotypes of Articulospora tetracladia, collected from a metal-polluted (At61) and a non-polluted (At72) stream, were assessed based on antioxidant enzymatic and proteomic responses. At61 showed more tolerance to AgNPs than At72 (EC, 158.

Ethanol and phenanthrene increase the biomass of fungal assemblages and decrease plant litter decomposition in streams.

Fungi, particularly aquatic hyphomycetes, have been recognized as playing a dominant role in microbial decomposition of plant litter in streams. In this study, we used a microcosm experiment with different levels of fungal diversity (species number and identity) using monocultures and combinations with up to five aquatic hyphomycete species (Articulospora tetracladia, Tricladium splendens, Heliscus submersus, Tetrachaetum elegans and Flagellospora curta) to assess the effects of ethanol and phenanthrene on three functional measures: plant litter decomposition, fungal biomass accrual and reproduction. Alder leaves were conditioned by fungi for 7days and then were exposed to phenanthrene (1mgL(-1)) dissolved in ethanol (0.

Morphological heterogeneity of Paracoccidioides brasiliensis: relevance of the Rho-like GTPase PbCDC42.

Paracoccidioides brasiliensis budding pattern and polymorphic growth were previously shown to be closely linked to the expression of PbCDC42 and to influence the pathogenesis of the fungus. In this work we conducted a detailed morphogenetic evaluation of the yeast-forms of 11 different clinical and environmental P. brasiliensis isolates comprising four phylogenetic lineages (S1, PS2, PS3 and Pb01-like), as well as a PbCDC42 knock-down strain.
