Implications of PDE4 structure on inhibitor selectivity across PDE families

the structure of lie derivations on c*-algebras

نشان می دهیم که هر اشتقاق لی روی یک c^*-جبر به شکل استاندارد است، یعنی می تواند به طور یکتا به مجموع یک اشتقاق لی و یک اثر مرکز مقدار تجزیه شود. کلمات کلیدی: اشتقاق، اشتقاق لی، c^*-جبر.

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Gradient intensity selectivity for scalar image restoration using PDE

Inhibition of PDE3B augments PDE4 inhibitor-induced apoptosis in a subset of patients with chronic lymphocytic leukemia.

PURPOSE cAMP phosphodiesterase (PDE) 4 is a family of enzymes the inhibition of which induces chronic lymphocytic leukemia (CLL) apoptosis. However, leukemic cells from a subset of CLL patients are relatively resistant to treatment with the PDE4 inhibitor rolipram, particularly when this drug is used in the absence of an adenylate cyclase stimulus such as forskolin. Elevated cAMP levels induce ...

Effect of inhibitor time-dependency on selectivity towards cyclooxygenase isoforms.

Cyclooxygenase (Cox) is a key enzyme in the biosynthesis of prostaglandins and, as such, is the target of non-steroidal anti-inflammatory drugs (NSAIDs). Two isoforms exist, being expressed constitutively (Cox-1), or inducibly in response to inflammatory mediators (Cox-2). Currently available NSAIDs inhibit both isoforms somewhat equipotently but selective Cox-2 inhibition may eliminate unwante...
