Mean values of different body dimensions in different age cohorts of children make it possible to learn a lot about their dynamic changes. Their comparative analysis, as is usually practiced, in fact leads to a simple description of changes in measur

We investigated, in cervical cancer, the relation between telomerase activity, telomerase RNA (hTR) and mRNA of the catalytic subunit of telomerase, hTERT, with "classic" clinicopathological factors as well as survival. Frozen specimens were obtained

Results of break junction experiments are presented, measuring the resistance as a function of inter-electrode spacing in vacuum tunnel junctions of Sb at a temperature of 1.3 K. A pronounced deviation from exponential tunneling is observed, showing

It is shown that in mechanically controllable break-junctions made from CuMn dilute alloys the intensity of Kondo-effect structure in the dV/dI(V) characteristics follows an anomalous dependence on the concentration of magnetic impurities although th

New techniques are being employed to produce adjustable point contacts of atomic size. The conductance of the contacts is found to evolve in a stepwise fashion. The steps can, in principle, result from the atomic structure of the contact and from qua

The purpose of this study was to analyze (1) the prognostic factors for survival of T1 and T2 carcinoma patients and (2) the impact of the initial groin node status for the time to recurrence and site of recurrence. We performed a follow-up study on

The signal transduction pathway by which insulin stimulates glucose transport is largely unknown, but a role for tyrosine and serine/threonine kinases has been proposed. Since mitogen-activated protein (MAP) kinase is activated by insulin through pho

Between 1982 and 1992, 32 patients with squamous cell vaginal cancer were treated. Fourteen patients had stage I, 11 stage II, two stage III and five stage IV disease. The mean age of stage I and II patients was 64, of stage III and IV patients 73. S

A mechanically controllable break junction is used to study the transition between vacuum tunneling and contact for three different metals. In the tunnel regime a faster-than-exponential behavior is seen at close distances, followed by a jump to cont
