Preliminary histopathological analyses (data not shown) have revealed that at mid-lactation, lobulo-alveolar differentiation is incomplete in transgenic glands, and further studies of this process and of involution at both the histological and molecular levels are in progress.
While these varied deformations are clearly attributed to crude oil exposure, it is unknown what early embryonic processes at the cellular or molecular levels are directly affected.
In PD, the compensatory mechanisms at cellular and molecular levels are centered in protection against neurotoxicity [ 105, 106] and neurogenesis and reinnervation of affected areas [ 107].
Future studies on the ability of viscous polymers to penetrate and interact with highly hydrated proteoglycan glycosaminoglycan complexes, particularly at the nanoscale and molecular levels, are encouraged to provide insights into the topics raised in this review.
The overall picture is by far more complex than previously thought; biological interactions that take place at lower molecular levels are characterized by unpredictable nonlinear dynamics and become tightly influenced by higher-level organizational constraints [ 12].
A great number of dynamic responses to water deficit at physiological, biochemical, and molecular levels are presented in plant, thus enabling them to survive under drought environmental conditions [ 3, 4].
