Iodinated contrast media cause both immediate and nonimmediate hypersensitivity reactions. The aim of this prospective study was to determine the specificity sensitivity skin tests in patients who have experienced such reactions.Skin prick, intradermal patch with a series were conducted 220 either or reaction. Positive defined according internationally accepted guidelines. Seventy-one never-exposed subjects 11 had tolerated medium exposure, served as negative controls.Skin test 96-100%. For...
All iodinated contrast media (CM) are known to cause both immediate (≤1 h) and nonimmediate (>1 hypersensitivity reactions. Although for most reactions an allergic cannot be demonstrated, recent studies indicate that the severe may IgE‐mediated, while of exanthematous skin reactions, appear T‐cell mediated. Patients who experience such therefore advised undergo allergologic evaluation. Several investigators have found testing useful in confirming a CM allergy, especially patients with...
Abstract. Marine diazotrophs convert dinitrogen (N2) gas into bioavailable nitrogen (N), supporting life in the global ocean. In 2012, first version of oceanic diazotroph database (version 1) was published. Here, we present an updated 2), significantly increasing number situ diazotrophic measurements from 13 565 to 55 286. Data points for N2 fixation rates, cell abundance, and nifH gene copy abundance have increased by 184 %, 86 809 respectively. Version 2 includes two new data sheets...
Abstract Dinitrogen (N 2 ) fixation supports marine life through the supply of reactive nitrogen. Recent studies suggest that particle-associated non-cyanobacterial diazotrophs (NCDs) could contribute significantly to N contrary paradigm diazotrophy as primarily driven by cyanobacterial genera. We examine community composition NCDs associated with suspended, slow, and fast-sinking particles in North Pacific Subtropical Gyre. Suspended slow-sinking showed a higher abundance than particles,...
One to three percent of patients exposed intravenously injected iodinated contrast media (CM) develop delayed hypersensitivity reactions. Positive patch test reactions, immunohistological findings, and CM-specific proliferation T cells in vitro suggest a pathogenetic role for cells. We have previously demonstrated that cell clones (TCCs) show broad range cross-reactivity different CM. However, the mechanism specific CM recognition by receptors (TCRs) has not been analysed so far.To determine...
Abstract. Over the next decade, Baltic Sea is predicted to undergo severe changes including decreased salinity due altered precipitation related climate changes. This will likely impact distribution and community composition of dinitrogen-fixing (N2-fixing) microbes, among which heterocystous cyanobacteria are especially adapted low salinities may expand waters with currently higher salinity, Danish Strait Kattegat, while other high-salinity-adapted N2 fixers might decrease in abundance. In...
Abstract Biological dinitrogen (N 2 ) fixation is the pathway making large pool of atmospheric N available to marine life. Besides direct rate measurements, a common approach explore potential for in ocean mining based on molecular genetic methods targeting key functional gene nifH , coding subunit nitrogenase reductase. As novel sequencing and single cell techniques improved, our knowledge diversity fixers grew exponentially. However, date one aspect commonly left aside. This existence two...
Dinitrogen (N2) fixation represents a key source of reactive nitrogen in marine ecosystems. While the process has been rather well-explored low latitudes Atlantic and Pacific Oceans, other higher latitude regions particularly Indian Ocean have chronically overlooked. Here, we characterize N2 diazotroph community composition across nutrient trace metals gradients spanning multifrontal system separating oligotrophic waters subtropical gyre from high chlorophyll Southern Ocean. We found sharp...
Miniature pigs appear to be less sensitive than rabbits cholera toxin introduced into segments of the ileum.
Oxygen minimum zones (OMZs) have been suggested as a suitable niche for the oxygen-sensitive process of biological fixation dinitrogen (N 2 ) gas. However, most N rates reported from such waters are low. This low activity has proposed to result unusual community fixers, in which cyanobacteria were typically underrepresented. The Northern Benguela Upwelling System (North BUS) is part one productive marine ecosystems and hosts well-developed OMZ. Although previous observations indicated absent...
Biological dinitrogen (N 2 ) fixation is the pathway making large pool of atmospheric N available to marine life. Besides direct rate measurements, a common approach explore potential for in ocean screening-based targeting key functional marker gene nifH , coding subunit nitrogenase reductase. As novel sequencing techniques improved, our understanding diversity fixers grew exponentially. However, one aspect often underexplored, which are two alternative types enzyme fixation, nitrogenase....
Microbial plankton is essential for ocean biogeochemistry. As part of the prokaryotic phototrophic microbial community, both oxygenic phototrophs (OP) and anoxygenic (AP) are widely distributed in may play a significant role carbon flow oxygen production. However, comparative studies OP AP have received very little attention, even though their different roles might be important various marine environments, especially minimum zones (OMZ). We explored spatial distribution community Baltic Sea,...
Stable hybrids were obtained by protoplast fusion between Bacillus subtilis and Zymomonas mobilis. All the able to hydrolyse starch possessed ampicillin‐ tetracycline‐resistant phenotypes. Two of hybrids, BZ‐1 BZ‐2, hyperproducers alpha‐amylase. The enzyme produced these exhibited increased thermostability. results show that stable intergeneric gene transfer can be achieved through poly(ethylene glycol)‐mediated two industrially important genera bacteria.
