Three signatures were attributed to exogenous exposures: tobacco smoke, UV radiation, and temozolomide.
The objective is to discern to what extent model performance, expressed by a variety of metrics, can be attributed to endogenously modeled processes or to exogenous model inputs.
It is unclear if this change can also be attributed to 'endogenous' factors or whether it is due to exogenous factors such as behavioral changes (e.g., the widespread use of the internet for anonymous sexual encounters).
Water spray resulted in some improvement in growth, indicating that the growth promotion by exogenous treatments could partly be attributed to water.
Hence, reduced phosphorylation of NR-Ser at high exogenous H2O2 concentrations cannot be attributed to failure of the antibodies to bind to the phosphorylated Ser sequence when the nearby Met is oxidized.
Thus, the induction of ectopic cerebellar neurons by exogenous FGF application can be attributed to the down-regulation Otx2 in the midbrain [ 6, 7] or Hoxa2 in the hindbrain [ 24], recapitulating the molecular characteristics of r1.
Ninety-three per cent of patients with RDS died, a factor that may be attributed to the lack of mechanical ventilation and the unavailability of exogenous surfactant.
The beneficial effect of insulin is perceived to be attributed to the promotion of immunologic tolerance, alterations in metabolism (i.e., exogenous insulin reducing the metabolic burden of the β-cells), or a combination of both mechanisms (3, 4).
Indeed, only a small portion of these developmental aberrations can be attributed to defects in the synthesis of testosterone or adrenal steroid hormones, receptor alterations, exogenous modifiers or obvious numerical and structural chromosomal alterations, such as Klinefelter syndrome.
All these symptoms may be attributed to the blockade of glucocorticoid receptors and an improvement of these manifestations with an exogenous corticosteroid treatment was described [ 29, 31].
