The uroepithelium of the bladder forms an impermeable barrier that is maintained in part by regulated membrane turnover in the outermost umbrella cell layer. Other than bladder filling, few physiological regulators of this process are known. Western blot analysis established that all four adenosine receptors (A1, A2a, A2b, and A3) are expressed in the uroepithelium. A1 receptors were prominentl...

The umbrella species concept is a frequently used in conservation since the of an may benefit other species. Keystone are often suggested as potential species, but validity this approach remains uncertain. Moreover, climate change can have multidirectional effect on distribution which be affected differently than that beneficiary applying thus jeopardised by change. This study assessed two keys...

Suppose your utility for an umbrella is 1, and for no umbrella is 0; suppose further that your subjective probability for rain is 1/2. Then acts A and B have utilities 1/2 and 1 respectively. On the other hand, I don’t think it would be unreasonable for you to be indi¤erent between the two acts, since an umbrella is useless in fine weather. Obviously, the answer is that your utility for umbrell...
