A promising candidate for a combined radiochemotherapy seems to be topotecan, a topoisomerase I inhibitor with a well established activity in the systemic treatment of SCLC (von Pawel et al, 1999) and NSCLC (Stewart, 2004), a high brain capillary permeability (Sung et al, 1994; Baker et al, 1996) and radiosensitising effects (Kim et al, 1992; Lamond et al, 1996).
In addition to the well established activities of the sirtuins, "long chain" acyllysine modifications were also shown to be prone to hydrolytic cleavage by SIRT1-3 and SIRT6, supporting recent findings.
It is well established GPx activity parallels serum selenium levels [ 50, 51] and selenium deficiency is associated with subnormal levels of selenoproteins [ 52].
Hdac6 has well established deacetylase activity directed against several cytoplasmic proteins, most notably tubulin (Hubbert et al., 2002), leaving open the possibility that, in stem cells, it may deacetylate some nuclear protein(s) that remain to be discovered.
Firstly, in current literature it is not recommended for the specific use of collect samples for the detection of Mycobacterium tuberculosis (MTB) in children [ 18]; secondly, local anesthetics have a well established antimicrobial activity versus bacteria and fungi [ 33- 35].
Early studies of orexin effects suggested that orexin results in the activation of motor activity, 119, 120 and it is well established that physical activity is correlated with both activation of orexin neurons 116, 117 and increases in OXA release.
Although it is well established that aromatase activity exists in stromal cells in endometriotic tissues, and this activity is well characterised, the presence and the role of aromatase in epithelial cells are largely unknown.
It is well established that cortical activity representing phantom hand movements is preserved in the sensorimotor cortex14,16.
It is well established that neural activity can trigger synaptic changes, such as long-term potentiation (LTP) and long-term depression (LTD), which are cellular models of learning and memory.
It is well established that hippocampal activity is positively related to effective associative memory formation.
However, it has also been well established that fLuc activity can be highly sensitive to its surrounding environment.
