Final report on the key comparison, CCM.P-K15 in the pressure range from 1.0 × 10 Pa to 1.0 Pa.

The comparison CCM.P-K15 is a key comparison in pressure involving six laboratories in three regional metrological organizations (RMO). The measurand of the comparison is the accommodation coefficient of two spinning rotating gauge characterized in nitrogen from 0.

Frequent infection of neurons by SV40 virus in SIV-infected macaque monkeys with progressive multifocal leukoencephalopathy and meningoencephalitis.

Simian virus 40 (SV40), family Polyomaviridae, in immunocompromised macaques can cause fatal demyelinating central nervous system disease analogous to progressive multifocal leukoencephalopathy caused by John Cunningham (JC) virus in immunocompromised humans. Recently, we have demonstrated that JC virus can infect cerebellar granule cell neurons and cortical pyramidal neurons in immunosuppressed people. To examine whether SV40 neuronal infection occurs spontaneously in immunosuppressed macaques, we analyzed archival brain specimens from 20 simian immunodeficiency virus-infected rhesus with AIDS and 1 cynomolgus post-transplant selected with SV40 brain infection from archival records from 1991 to 2012.

Comparison of two methods for the detection of urinary iodine used in epidemiological studies.

Two methods for the determination of iodine in urine or serum based on the Sandell-Kolthoff reaction were compared. The first was an autoanalyser method (AAII, Technicon) where the mineralisation takes place in a continuous flow manner. This procedure was used at the Department of Clinical Chemistry of the University Hospital of Berne (Switzerland) from 1968 until 1993.

[Clinical aspects of depressive states].

During the last 4 years (1979-1982), 4117 patients have been examined in our out-patient department. Since the most important dates of each patient are electronically registered, it was easy to ascertain the frequency of the depressive conditions with the computer. This amounts to 819 and corresponds to 19.
