Secretory canals containing yellow, red, or brown tannins, for example, are frequent.
The antiviral capacity of NK cells is even more important, as Epstein Barr virus (EBV) or cytomegalovirus (CBV) infections, for example, are frequent complications of prolonged immune deficiency [24], [25].
Dogs, for example, are frequent victims of venomous snakebites that may be triggered more by curiosity and approach by the dogs rather than accidentally disturbing a resting snake.
Civil war, for example, is frequent and often leads to the destruction of healthcare systems.
For example, there are frequent cases in which commercial airlines are held on the ground at their originating airport until they receive a clearance to land at a destination.
For example, if there are frequent deletions the reference model will be expected to have lower intensity signal thereby inducing a positive location bias.
For example, if symptoms are frequent and lung function normal, alternative or comorbid causes such as vocal cord dysfunction should be considered; if symptoms are few but lung function is low, poor perception of airflow limitation or a sedentary lifestyle should be considered.
For example, IDH1 mutations are frequent events in all grade II and III gliomas and in secondary glioblastomas (sGBM, glioblastomas that progress from lower grade gliomas) whereas primary GBMs (pGBM) are usually IDHwt and frequently have genetic changes involving the EGFR locus, PTEN deletions and TERT promoter mutations [ 4, 6, 12].
The examples are the frequent changes between Val, Ile and Ala that show similar chemical and physical properties.
However, field examples are less frequent and adaptive mechanisms are not as well understood for broadly distributed industrial pollutants that produce unintended consequences in non-target organisms.
