How can the examination failure rate be stabilised?

Background: The study programme in medicine at the Norwegian University of Science and Technology (NTNU) holds written examinations once annually. The limit to achieving a pass grade is at least 65 % correct answers. The failure rate varies from one year to the next.

Poly(p-phenylenevinylene) Derivatives with Defined Conjugation Segments and Post-Polymerization Modification with Sterically Enshrouded Chromophores.

Two poly(p-phenylenevinylene) derivative alternating copolymers (P1-I and P2-I) have been prepared featuring iodo substituents and m-phenylene units to periodically disrupt conjugation. P1-I was derivatized with various chromophores to yield P1a-f. In P1a-f, the chromophores were positioned within a sterically protected pocket shielding them from interchain interactions so that intrachain interactions between polymer segments could be observed.

New arguments to explain the high infection rate in posttraumatic spleenless patients.

To get more information about the high infection rate in splenectomized adult patients 211 spleenless patients were investigated with regard to clinical and laboratory data and compared to healthy blood donors. The results show that the infection rate is markedly increased to 30%. Splenectomized patients have decreased IgG levels which is due to diminished IgG1 and IgG4.

Conditions required for induction of murine p30 by herpes simplex virus.

Mouse cells (line N cIA cl10) contain 1.2-2.5 ng murine leukaemia virus (MuLV) p30 antigen/mg of protein; this amount of antigen is measurable by competition radioimmunoassay (RIA) but is not detectable by indirect immunofluorescence (IF).
