Many drugs follow a biphasic elimination curve — first a steep slope then a shallow slope: STEEP (initial) part of curve —> initial distribution of the drug in the body. SHALLOW part of curve —> ultimate excretion of drug, which is dependent on the release of the drug from tissue compartments into the blood.
Biphasic (or diphasic, bifurcated, or bimodal) sleep refers to two periods, while polyphasic usually means more than two. [1] Segmented sleep and divided sleep may refer to polyphasic or biphasic sleep, but may also refer to interrupted sleep , where the sleep has one or several shorter periods of wakefulness, as was the norm for night sleep in ...
Biphasic, meaning having two phases, may refer to: Phase (matter), in the physical sciences, a biphasic system, e.g. one involving liquid water and steam; Biphasic sleep, a nap or siesta in addition to the usual sleep episode at night; Phase (pharmacology) Biphasic disease; Biphasic formulations of oral contraceptive pills
Biphasic, biphasic-solute, triphasic (two solutes), and multiphasic materials with multiple solutes. Steady-state or transient analysis conditions. Special contact formulations that take solvent and/or solute flow across contact interface into account. Solid-bound molecules that deform with the solid phase.
The study of reproduction and development in organisms was carried out by many botanists and zoologists.. Wilhelm Hofmeister demonstrated that alternation of generations is a feature that unites plants, and published this result in 1851 (see plant sexuality).
Wellens' Syndrome is a pattern of biphasic T waves in V2–3. It is generally present in patients with ischemic chest pain. Type 1: T-waves are symmetrically and deeply inverted; Type 2: T-waves are biphasic with negative terminal deflection and positive initial deflection [5]
Biphasic calcium phosphate, BCP, was originally reported as tricalcium phosphate, but X-Ray diffraction techniques showed that the material was an intimate mixture of two phases, hydroxyapatite (HA) and β-tricalcium phosphate. [12] It is a ceramic. [13]
Among polypeptide-based methods, employing a phase transfer catalyst and triphasic media permits lower catalyst loadings. Biphasic conditions using an organic base in conjunction with urea/H 2 O 2 may also be used.
