A novel and efficient speciation method based on the nano-structured lead dioxide as stationary phase of head space solid phase microextraction combined with gas chromatography mass spectrometry (GC MS) was developed for the determination of volatile organoselenium compounds (dimethylselenide (DMSe) and dimethyldiselenide (DMDSe)) in different biological and environmental samples.
We showed the course of the concentration of serum S-100B in the acute phase of head injury using the YK-150.
Integrated radioactivity counts accumulated over a 60-s acquisition period beginning with the rising phase of head counts was used as an index of perfusion.
Recently, there have been several reports on the relation of the severity of head injury and serum S-100B protein levels in trauma patients, but there are few reports about time course of S-100B protein in the early phase of head injury.
Growth of the rice plant is divided into three phases: the vegetative (from germination to panicle initiation), reproductive (from panicle initiation to heading) and grain filling or ripening phase (from heading to maturity) (Li, 1979).
Two different pathways that lead to brain cell death are depicted in Figure 6, showing how calpain and caspase proteases may break down salmonid brain cellular proteins during both acute necrosis and delayed apoptosis phases of salmon head injury, respectively.
Mean (±SD) phase shifts of head-velocity during gaze-pursuit and head-pursuit (target stationary in space) were 0 (±6) and 1 (±3) deg lag, respectively.
In addition to those, the lateral interactions of hydrocarbon chains are also involved in surfactant adsorption after the first phase of surfactant head-rock surface adsorption is accomplished.
The gaze shifts of birds and flies are similar not only to the fact that there are phases of fast and slow head turns, but also to some parameter values of these phases.
The administration of a STAT3 decoy oligonucleotide was evaluated in a clinical phase 0 trial of head and neck tumours (NCT00696176).
These preclinical studies were further verified in two feasibility studies and one phase II study of head and neck carcinoma [ 28], renal cell carcinoma [ 29, 30] and melanoma [ 30].
