However, they can only assess the bioaccessibility of Pb, defined as the fraction of ingested Pb dissolved during the digestion process and available for absorption into the systemic circulation (bloodstream).
Because serum resistance might contribute to spread of C. jejuni in the bloodstream, systemic isolates have been studied for their survival in human serum.
The result, says Novavax, is likely the first moisturizing lotion that delivers a systemic drug to the bloodstream.
Hence, it is reasonable to assume that adaptation to variations in potassium concentration must play an important role in the pathogenicity of facultative intracellular pathogens, such as F. tularensis, which are also found free in the bloodstream during systemic dissemination.
S. cerevisiae and its commercially available preparations known as S. boulardii, that are used to treat antibiotic-related diarrhea, have been shown to cause a wide variety of infections, ranging from cutaneous infections and vaginitis to systemic infections of the bloodstream and vital organs in immunocompromised and immunocompetent individuals [20] [33].
In the context of Candida species, many are human commensals and able to disseminate into the bloodstream, causing systemic infections.
Finally, systemic delivery into the bloodstream is challenged by phagocytic immune cells, such as macrophages and monocytes, which remove complexed RNAs from the body.
These AE may cause local complications, which may be infectious or non-infectious or systemic complications, of which bloodstream infection is the most severe.
Although drug delivery and whole-body imaging using CNTs are highly effective procedures, major risk arises from their systemic circulation via the bloodstream.
Microbubble contrast agents administered intravenously into the systemic circulation allow the bloodstream's echo to be enhanced on ultrasonographic imaging, thus allowing blood to be distinguished from surrounding tissues and the evaluation of tumour vascularity and angiogenic activity.
