Special Issue on "Cdk5 and Brain Disorders": Prologue.

Cyclin-dependent kinase 5 (Cdk5) was identified almost two decades ago as a Tau kinase specific to the nervous system. Shortly after its discovery, it was revealed that this atypical member of the CDK family does not partner with cyclins but with two other proteins, p35 and p39. P35 is predominantly expressed in post-mitotic neurons, whereas p39 is expressed in many different tissues including ...

A Study on Structure and Property of Special Sulfonated Petroleum as a Complicated Anionic Surfactant

Alkaline/surfactant/polymer (ASP) flooding has been extensively applied to enhancing oil recovery. As an oil displacement agent, pe1troleum sulfonate (PS) is widely used in ASP pilot experiments. It is very important to find a petroleum sulfonate with a high interfacial activity and low adsorption loss. Anionic surfactant petroleum sulfonate is synthesized in a single-tube film sulfonation reac...
