8 One hypothesis for the association between shift work and breast cancer involves exposure to light at night and subsequent disturbances to the body's normal circadian (24-h) rhythms. 1 6 7 This is highly plausible given that melatonin, a hormone whose secretion by the pineal gland is stimulated by darkness and inhibited by light exposure, has demonstrated cancer-protective effects.
Ultrafast laser parallel processing using diffractive multi-beam patterns generated by a spatial light modulator (SLM) has demonstrated a great increase in processing throughput and efficiency.
Recently, we have characterized the effects of light on ctenophore photoprotein mnemiopsin, in different conformations, which has demonstrated light induced structural changes, uniquely secondary structures, of both apo and holo mnemiopsin.
Polarized light microscopy has been gainfully applied to embryology for decades, but recently a digital, orientation-independent polarized light microscope, the polscope, has demonstrated the exquisite sensitivity needed to image the low levels of birefringence exhibited by mammalian spindles.
These efforts have been augmented by the region's light-rail system, which has demonstrated that new commercial development will follow the building of transit stations, said Cal Marsella, the general manager of the Regional Transportation District.
In this context, it is noteworthy that a recent study has demonstrated light-independent O2 generation in multiple organelles other than the chloroplast under various biotic and abiotic stresses in plants (Mor et al., 2014).
Research in the last ten years has demonstrated that light energy can be used to power artificial nanomotors by exploiting photochemical processes in appropriately designed systems.
Despite investor fears about the leftist bent of President Luiz Inácio Lula da Silva when he was elected to lead Brazil in 2002, he has demonstrated a light touch when it comes to economic stewardship, avoiding the populist impulses of leaders in Venezuela and Bolivia.
Our method of blood loss calculation was chosen in light of previous work, which has demonstrated that measuring blood loss from swabs and suction drainage can lead to substantial underestimation of the actual loss (Sehat et al. 2004).
