Inspired by the recent Hubble Space Telescope first observations of arsenic in an astrophysical object we have determined the natural radiative lifetime of the upper states of two of the three resonance lines of As I. Short pulse laser excitation at 193.7 and 197.2 nm was achieved using different non-linear optical mixing schemes. Using time-resolved spectroscopy we obtain tau(4p(2)5s P-4(3/2))=4.

PURPOSE: To compare in vivo levels, spatial localization, and in vitro secretion of cysteine protease cathepsins and cystatin C (cysC) in the retinal degeneration 1 (rd1) mouse model of retinitis pigmentosa and control (wt) mouse retinas. METHODS: The spatial localization, protein contents, cysC levels and cathepsin-B, -S, and -L activities in wt and rd1 retinas at postnatal (PN) days 2, 7, 14, 21

The pathophysiology of acute pancreatitis involves activation of the pancreatic proenzymes. Levels of the trypsinogen activation peptide in urine in acute pancreatitis has been shown to correlate with the severity of disease. However, this peptide is unstable in urine and, because of its low molecular mass, difficult to measure. Procarboxypeptidase B has a larger activation peptide which could be

Despite the recent success of tyrosine kinase inhibitors (TKIs) in the treatment of chronic myeloid leukemia (CML), approximately 2-17% of patients develop clonal cytogenetic changes in the Philadelphia-negative (Ph(-)) cell population. A fraction of these patients, in particular those displaying trisomy 8 or monosomy 7, are at risk of developing a myelodysplastic syndrome (MDS) or acute myeloid l

In this study we investigated how mood influences the degree of realism in participants’ confidence judgments (based on an episodic memory task). Using music and film in combination, we successfully induced half of the participants into an elated mood, but failed to induce a sad mood in the other half. Contrary to our prediction, our data indicated that there was no difference in the realism of th

Aim. To measure levels of anxiety among people accompanying consumers to the emergency department and to explore how anxiety influences satisfaction with care. Background. When people seek treatment in an emergency department they are often accompanied by a next-of-kin, family member or friend. While the accompanying person plays a vital role in providing psycho-social support to consumers, little
