The engineering of bladder tissue involves obtaining a biopsy from a host, expanding the cells, seeding them onto a matrix and implanting the cell-matrix composite back into the host.
This may allow pathogen persistence in new areas and facilitate pathogen spread as the invasive host expands its range.
As our understanding of the elaborate symbiotic relationship between the human microbiome and the host expands, strategies for modulating the latter have evolved.
These cells are particularly important for disease progression, because they may colonize other sites in the host, expanding the infection or, in the worst case scenario, starting a disseminated infection [ 31].
LONDON — The number of people who said they were sexually assaulted by Jimmy Savile, one of Britain's most popular television hosts, expanded to 300 from 200 in just the last week, and other people may have acted with him, the Scotland Yard officer heading the investigation said Thursday.
Our hypothesis is that the hantaviruses co-evolved with their animal hosts, such as SEOV with rats and HTNV with striped mice, but when their animal hosts expanded their territory, hantavirus had more chance to infect other susceptible rodents and expanded their animal hosts.
To wit: on-demand cleaning startup Handy is today launching a hospitality service tailored for vacation rental hosts — expanding on an existing cleaning offering for Airbnb hosts, launched as a pilot in New York back in January 2014.
Eukaryotic hosts expand their ecological niches through symbiosis with these metabolically diverse bacteria and archaea.
These may represent high-risk locations, where reassortment could facilitate evolutionary innovation and lead to the emergence of novel lineages with the capacity to evade host immunity, expand host ranges, or overcome treatment interventions.
So rather than finding a way to make the tournament work in a single country, Uefa has turned logic on its head and will use the whole of Europe as its playground to host an expanded one.
