Differences in the traffic profile are likely accountable for this discrepancy: Cu is a marker of light-duty vehicle brake wear, whereas barium and antimony are characteristic of brake wear from heavy-duty vehicles (Sternbeck et al. 2002).
5 Conflicting results on the effects of gestational alcohol consumption on offspring health outcomes and subsequently, lack of coherence in clinical and government guidelines stem from a lack of biological markers of light or moderate alcohol use during pregnancy.
Spectral differences between oocytes are linked with two aspects of oocyte morphology, namely, with the structure of the zona pellucida (thin or large and compact) and cytoplasmic coloration, which are main markers of light absorbance rate and spectral features of the gametes.
Using the expression of c-fos as a marker of cellular light activation in vivo [ 16 18], we confirm the spectral tuning of retinal ganglion cells by cone opsin gradients and demonstrate that the responses of pRGCs are spectrally tuned depending on their location in the retina.
67 Consistent with these findings in muscle, augmentation of autophagic markers, cleavage of light chain 3 (LC3), and autophagic ultrastructural alterations were found in the brain of klotho-deficient mice, similarly to those found in aged wild-type animals.
As one of critical negative factor in the transcription-feedback loops of the clock genes, Per1 has been identified as a molecular marker of entrainment by light, which is a kind of predictable environmental stimuli [22].
More specifically, we tested the validity of using BrdU as the first marker, in light of the evidence that indicates its possible toxicity (see above).
At around 3000 BC, Stonehenge acted as both a temple of light and a marker of the important seasonal changes predicted by the movement of the Sun.
Depletion of C9ORF72 using siRNA inhibited transport of Shiga toxin from the plasma membrane to Golgi apparatus, internalization of TrkB receptor and altered the ratio of autophagosome marker light chain 3 (LC3) II:LC3I, indicating that C9ORF72 regulates endocytosis and autophagy.
