The resultant effect is a new, constantly changing, and complex treatment paradigm for treating clinicians, who are now required to know the mechanism of actions of new medications, side effect profiles, modes of administration, and preferred sequencing of various treatment options.
Cerebral arteriovenous malformations (AVMs) are easily displayed by conventional MRI and MR angiography because of their characteristic high flow, whereas venous malformations such as cavernomas, developmental venous anomalies and capillary telangiectasias cannot be adequately visualised without contrast medium administration and GE sequences, as they mainly consist of slow-flow small vessels.
The images consisted of axial cross-sectional and sagittal T2-weighted fast spin-echo, sagittal T1-weighted non-fat-suppressed, T1-weighted fat-suppressed DCE before and after contrast material administration, and DW sequences prior to gadolinium-based contrast material injection in axial orientation.
There are critical end points in the design of future clinical trials to determine the optimal forms of selenium types and administration dose, schedule, and sequences in combination with chemotherapeutic agents that have direct cytotoxic effects against tumour.
In these studies, the timing and sequencing of TAM administration relative to RT were either variable or not reported.
Because the ratio of the OP or CM pesticides in the mixture, the sequence of administration, and the timing of the administration can all have a marked influence on the toxicity profile of a mixture, more research investigating these relationships is needed to define comprehensively the interaction profile of a group of pesticides.
Similarly, in vitro studies have shown that the effects of a combination of DXR and gemcitabine depend both on the sequence of administration and on the particular cell line studied (Chow et al, 2000; Zoli et al, 2004).
Varying the sequence of rapamycin administration and cell injection did not increase responsiveness of the IO33 cells (data not shown).
Synergy was not dependent on a specific sequence of drug administration and was also observed when CNDAC was combined with an alternative HDAC inhibitor, valproate.
The questionnaire and structured interview are computerized with skip sequences to speed administration and eliminate inappropriate questions (e.g., pregnancy for males or detailed questions on medical treatment when there had been no musculoskeletal disorder).
