[A survey on surgical training during residency in Sweden - description of the current state].

Practical training for new surgeons differs between institutions, and standards are mostly lacking. The largest problems seem to occur during the first years, when novices begin their specialty training, (specialisttjänstgöring in Swedish). A large number of scientific publications are available, but the they are usually limited to one specific procedure or one surgical specialty, and the results are rarely applied in practice.

MARK4 and MARK3 associate with early tau phosphorylation in Alzheimer's disease granulovacuolar degeneration bodies.

Background: The progression of Alzheimer's disease (AD) is associated with an increase of phosphorylated tau in the brain. One of the earliest phosphorylated sites on tau is Ser262 that is preferentially phosphorylated by microtubule affinity regulating kinase (MARK), of which four isoforms exist. Herein we investigated the expression of MARK1-4 in the hippocampus of non-demented elderly (NDE) and AD cases.
