Tris-hydroxymethyl-aminomethane (THAM) has been evaluated in ischemic stroke to reduce mass effect and ICP. It acts as a bulfer, neutralizing acidosis on a local level, including in the brain parenchyma. It has been studied in animal models of stroke, showing an effect in reducing the size of and swelling from cerebral infarction. To date, however, THAM has not been studied in a controlled fashion in humans with ischemic stroke. [Pg.175]

There is a similar situation related to substitution in a nearby unstable site. Thus tert-butyl peroxide can be handled whereas butyl peroxide cannot. These are static effects, not to be confused with mass effects (see later). [Pg.98]

Mass effects due to some ions in salts. It is generally observed that there is a greater instability amongst compounds containing heavy atoms compared with elements in the first periods of the periodic tabie.This can be observed by analysing enthalpies of formation of ammonia, phosphine, arsine and stibine (see previous table for the last three). In the same way, it is easier to handle sodium azide than lead azide, which is a primary explosive for detonators. It is exactly the same with the relatively highly stable zinc and cadmium thiocyanates and the much less stable mercury thiocyanate. [Pg.99]

It has been forty-five minutes since CH s arrival, and he has been given lorazepam 4 mg twice and loaded with 1500 mg of phenytoin. He received another 400 mg dose of phenytoin 15 minutes ago, but is still unarousable. His jerking movements have slowed down, but his temperature is now 39.9°C (103.8°F), and his blood pressure has dropped to 124/62 mm Hg. His oxygen saturation is 91% on 4 L oxygen via nasal cannula. Bilateral crackles are heard upon auscultation of his lungs. A CT scan of his head is obtained which shows no evidence of hemorrhage, tumor, or mass effect. [Pg.466]

The presence of blood in the brain parenchyma causes damage to surrounding tissue through a mass effect and the neurotoxicity of blood components and their degradation products. Compression of tissue surrounding hematomas may lead to secondary ischemia. Much of the early mortality of hemorrhagic stroke is due to an abrupt increase in intracranial pressure that can lead to herniation and death. [Pg.170]

Arrests, the loss of sanctuary and the freezing of assets have diminished some threats, but it has spawned others as terrorists adjust to being the focus of the global war on terrorism. What will be the balance Will loss of sanctuary and financial resources prevent terrorists from developing or acquiring CBRN that can be used to mass effect Or will the global war on terrorism embolden terrorists and states to share and use CBRN While terrorists continue to use traditional weapons in innovative ways, a primary concern is terrorist adoption of CBRN weapons in the future. The potential for this is explored next. [Pg.39]

The fraction of released energy that passes into translational and vibrational energies of product depends to a quite significant extent on the mass combination of reactant atoms. This mass effect is referred as kinematic effect. In order to understand mass effect, at least for a collinear reaction, we can transform the motion of the three particles on PES to that of a single... [Pg.237]

The mass effect can also explain the reactivity of two ends of molecule in its reaction. For example, in reaction... [Pg.239]

A and BC approach to centre of mass, A strips off B and then AB and C return roughly in the direction from which they came. These reactions are said to occur by a rebound mechanism and generally occur when the surface are repulsive. In such reactions the life-time of activated complex, i.e. (ABC) must be short and reaction is said to be direct or impulsive. If life-time is much, rotation may occur and the products may separate in random directions. For many such reactions, the life-time of complexes has been observed less then 5 x 10 13sec. J.C. Polanyi discussed the relationship of these reactions with shapes of PES with special attention to mass effects. [Pg.244]

Hydroxylic solvents are capable of solvating anions through hydrogen bonding, and so halide mobilities are relatively low in alcohols, with chloride the least mobile. The mobility decreases observed for all the halides upon going up the homologous series of aliphatic alcohols may be the result of the increased size and mass of the alkyl group. A similar mass effect may be seen in the lowered mobility of the halides in dimethylacetamide compared to dimethylformamide. Here, as in the alcohol series, dipole moments and viscosities of the two solvents do not appear to be sufficiently different to explain the mobility differences. [Pg.54]

The second kind of NMR isotope effect has its origin in the mass differences between isotopes. In NMR mass effects show up as isotopic differences in NMR shielding constants and coupling constants. Their theoretical rationalization is... [Pg.226]
