Two-dimensional relayed NOESY experiments (Wagner, 1984 Kessler et al., 1988) give cross-peaks that could be a superposition of nOe s resulting from different relay nuclei. This complicates the extracting of crossrelaxation rates. The 1D NOESY experiment (Kessler et al., 1989a), however, allows the path of the magnetization transfer to be clarified. 

Mouse vas deferens (MVD) seems to express CB1 and at least one CB2-like cannabinoid receptor type, as is demonstrated by the presence of CB1 and CB2-like mRNA as well as by data collected from experiments with cannabinoid receptor selective agonists and antagonists (Pertwee, 1999). Furthermore, evidence indicates that a CBl-like receptor exists in vascular endothelium, which upon activation produces significant hypotension (Wagner, 1999). This receptor differs from CB1 in its pharmacological response to some well-characterized cannabimimetics.

The increase of temperature with time in a hydrogen evolution experiment introduces an additional time dependence to the diffusion coefficient. The sample temperature is described by T = 7) + bt where 7) is the initial starting temperature. Previous analysis of the hydrogen evolution curves to extract a >H value have assumed that the only time dependence of >H arises from the heating rate term in T(t) (Beyer and Wagner, 1982). It turns out that the power-law time dependence of Z)H can be safely neglected in the evolution analysis. The effective diffusion time in a hydrogen evolution experiment with b = 20 K/min is less than one hour, so the decrease in...

Among elderly women as much as 80% suffer from involuntary voiding of the bladder, urinary incontinence (UI). In the United States approximately 12.5 million people are affected by incontinence and a European study showed a prevalence of between 12% and 22% in all ages and an increase to 30-40% in ages over 75 years (Hampel et al. 1997). Women experience UI twice as often as men. Incontinence becomes more common in old age, with existing co-morbidity of all kinds and life styles (Box 5.5). There are different forms of urinary incontinence and they differ in cause and treatment. This problem causes not only personal distress but also a considerable cost for society as a whole (Jackson 1997). Lower quality of life is often reported in people with UI and the risk increases by the withdrawal from social interaction and participation in sports and other activities. An estimated cost for the care of patients with UI in the United States was approximately 26 billion dollars in year 1995 (Wagner and Hu 1998). Other studies have come up with a calculated cost that represents two percent of the total national health budget.
