Analysis of marine cyanobacteria and proteobacteria genomes has provided a profound understanding the life strategies these organisms their ecotype differentiation metabolisms. However, comparable analysis Bacteroidetes, third major bacterioplankton group, is still lacking. In present paper, we report on genome Polaribacter sp. strain MED152. On one hand, MED152 contains substantial number genes for attachment to surfaces or particles, gliding motility, polymer degradation. This agrees with...
We combined denaturing gradient gel electrophoresis (DGGE), catalysed reporter deposition-FISH (CARD-FISH) and clone libraries to investigate the seasonality of bacterial assemblage composition in north-west Mediterranean coastal waters. DGGE analysis indicated that diversity changed gradually throughout year, although with a clear distinction summer period. Alphaproteobacteria were dominant group on an annual basis [29% DAPI (4′,6-diamidino-2-phenylindole) counts by CARD-FISH, 70% clones]....
Summary We collected surface samples in Franklin Bay (Western Arctic) from ice‐covered to ice‐free conditions, determine seasonal changes the identity and situ activity of prokaryotic assemblages. Catalysed reported fluorescence hybridization was used quantify abundance different groups, combined with microautoradiography fraction active cells taking up three substrates: glucose, amino acids ATP. In waters, Archaea accounted for 16% total cell count winter, but decreased almost undetectable...
Animal models showed that angiogenesis is related to abnormal heart development. Our objectives were ascertain whether a relationship exists between congenital defects (CHDs) and angiogenic/anti-angiogenic imbalance in maternal foetal blood study the expression of angiogenic factors heart.Maternal cord placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFlt-1) endoglin (sEng) compared 65 cases CHD 204 normal controls. Angiogenic markers hypoxia measured tissue from 23...
An annual seasonal cycle of composition a bacterioplankton community in an oligotrophic coastal system was studied by denaturing gradient gel electrophoresis (DGGE) using five different primer sets. Analysis DGGE fingerprints showed that set 357fGC-907rM grouped samples according to seasons. Additionally, we used the 16S rRNA genes archived RDPII database check percentage perfect matches each for most abundant bacterial groups inhabiting plankton communities. Overall, suitable routine use...
Understanding the pathogenesis of small-for-size (SFS) syndrome is critical to expanding applicability partial liver transplantation. We aimed characterize its acute presentation and association with alterations in hepatic hemodynamics, microstructure, regeneration a porcine model. Eighteen SFS transplants were performed. Donors underwent 70% hepatectomy. Partial grafts implanted into larger recipients. Whole also performed (n = 6). Recipients followed until death or for 5 days. Hemodynamics...
Current output of microbial fuel cells (MFCs) depends on a number engineering variables mainly related to the design cell reactor and materials used. In most cases MFCs relies premise that for constant biomass, current correlates well with metabolic activity cells. this study we analyze what extent, MFC is also affected by mode operation, emphasizing how discontinuous operation can affect temporal patterns output.The experimental work has been carried out Shewanella oneidensis MR-1, grown in...
Marine sediments impacted by urban and industrial pollutants are typically exposed to reducing conditions represent major reservoirs of toxic mercury species. Mercury methylation mediated anaerobic microorganisms is favored under such conditions, yet little known about potential microbial mechanisms for detoxification. We used culture-independent (metagenomics, metabarcoding) culture-dependent approaches in anoxic marine identify indicators pollution analyze the distribution genes involved...
Summary Microbial consumption is one of the main processes, along with photolysis and ventilation, that remove biogenic trace gas dimethylsulfide (DMS) from surface ocean. Although a few isolates marine bacteria have been studied for their ability to utilize DMS, little known about characteristics or phylogenetic affiliation DMS consumers in seawater. We enriched coastal open‐ocean waters different carbon sources stimulate bacterial communities (glucose‐consuming bacteria, methyl...
Recent studies pointed to an intrinsically angiogenic imbalance in CHD the maternal and foetal circulation suggestive of impaired placentation.To assess whether pregnant women with a foetus are at greater risk placenta-related complications.Perinatal results CDH were compared those non-selected population followed up our centre. Multiple pregnancies chromosomal abnormalities excluded from analysis.About 279 foetuses included. Mothers classified three groups according cardiac defect: 104...
Marine sediments polluted from anthropogenic activities can be major reservoirs of toxic mercury species. Some microorganisms in these environments have the capacity to detoxify pollutants, by using mer operon. In this study, we characterized microbial cultures isolated marine growing under diverse environmental conditions salinity, oxygen availability and tolerance. Specific growth rates percentage removal were measured batch for a selection isolates. A culture affiliated with Pseudomonas...
In partial liver transplant, a reduction in the intrahepatic vascular bed produces rise portal vein flow and venous pressure gradient, leading to endothelial and, thereby, hepatocellular injury death process known as "small-for-size" (SFS) syndrome.To demonstrate that calibrated portocaval shunt prevents superfluous inflow porcine model of SFS transplant.Donor pigs (15-20 kg) underwent 70% hepatectomy. 2 groups, 6 mm (S6) (n = 6) or 12 (S12) Gore-Tex was placed between infrahepatic inferior...
Down's syndrome (DS) is characterized by a complex phenotype associated with chronic oxidative stress and mitochondrial dysfunction. Overexpression of genes on chromosome-21 thought to underlie the pathogenesis major phenotypic features DS, such as premature aging. Using cultured fibroblasts trisomy 21 (T21F), this study aimed ascertain whether an imbalance exists in activities, mRNA, protein expression antioxidant enzymes SOD1, SOD2, glutathione-peroxidase, catalase during cell replication...
Abstract Background Isolation of marine microorganisms is fundamental to gather information about their physiology, ecology and genomic content. To date, most the bacterial isolation efforts have focused on photic ocean leaving deep less explored. We created a culture collection heterotrophic bacteria (MARINHET) using standard medium comprising total 1561 strains, covering variety oceanographic regions from different seasons years, 2009 2015. Specifically, our contains isolates both (817)...
Clinical and epidemiological characteristics of diarrhea associated with Vibrio mimicus were identified in 33 hospitalized patients referred to the Costa Rican National Diagnostic Laboratory Network between 1991 1994. The relevant symptoms presented by included abundant watery diarrhea, vomiting, severe dehydration that required intravenous Dhaka solution 83% but not fever. Seroconversion against V. was demonstrated four patients, from whom acute- convalescent-phase sera obtained. Those did...
