Alternatives: "a context of decline" or "a backdrop of reduction".
In fact, co-occurrence of BRCA1 and DPYD rearrangements, as observed in our study, may reflect a background of decreased DNA repair capacity (Weigman et al, 2012) and, thus, suggest increased vulnerability of these TNBC tumours towards DNA-damaging agents such as radiation, DNA-intercalating anthracyclines or alkylating cyclophosphamide.
On the background of decreased ascorbate availability this demonstrates that the photosynthetic electron transport chain was otherwise protected.
The collective immunity is specified at the level of 10%, which in our opinion may actually fit the natural background of decreased individual susceptibility to relatively small infective doses at random contacts between infected and healthy persons.
Two of the 44 new confirmed clusters occurred against a background of a significant decreasing trend, and two occurred in association with an increasing trend and may have been a manifestation of that trend.
Taking into account that the HER2+/LC3A+ cell population increases after Trastuzumab, on a background of an overall decrease of HER2+ total population, we suggest that breast cancer cells expressing LC3A are resistant to Trastuzumab cytotoxic effect and persist in post-therapy biopsies.
Trend analysis shows that this is significantly greater than the background trend of decreasing admissions.
A background of precipitation-induced conductivity will decrease the relative difference in conductance between sunlit and dark conditions, explaining the smaller dark/sunlit difference in the pre-noon currents on the dayside compared to the afternoon current.
SCC is an immunogenic tumour, arising against a background of cellular immunodeficiency with lymphopenia, decreased T cell and macrophage function and anergy, and it has been suggested that there is deterioration in the immunologic status in SCC (Richtsmeier, 1997).
Expression of BRCA1 or p63 in a background of low BRCA1 and p63 results in decreased cell proliferation.
Against the background of a decreasing number of general practitioners (GPs) in rural regions in Germany, the AGnES-concept (AGnES = GP-supporting, community-based, e-health-assisted, systemic intervention) supports the delegation of regular GP-home visits to qualified practice assistants.
