Count-rate management in I SPECT/CT calibration.

Background: System calibration is essential for accurate SPECT/CT dosimetry. However, count losses due to dead time and pulse pileup may cause calibration errors, in particular for I, where high count rates may be encountered. Calibration at low count rates should also be avoided to minimise detrimental effects from e.

Short- and Long-Term Effects on Physical Fitness in Older Adults: Results from an 8-Week Exercise Program Repeated in Two Consecutive Years.

: Information on the long-term maintenance of short-term exercise fitness gains measured by field-based tests is scarce in older adults. This study aimed to investigate short- and long-term changes in various physical fitness parameters after an 8-week exercise program. : In this longitudinal study, a total of 265 participants (62% women; mean age 71.

Assessment of access and outcomes of kidney transplantation through the reforms of the Swiss organ allocation system.

Introduction: The Swiss allocation system for kidney transplantation has evolved over time to balance medical urgency, immunological compatibility, and waiting time. Since the introduction of the transplantation law in 2007, which imposed organ allocation on a national level, the algorithm has been optimized. Initially based on waiting time, HLA compatibility, and crossmatch performed by cell complement-dependent cytotoxicity techniques, the system moved in 2012 to a score including HLA compatibility, waiting time, anti-HLA antibodies detected by the Luminex technology, and a virtual crossmatch.

The Transcriptomic and Gene Fusion Landscape of Pleomorphic Salivary Gland Adenomas.

Pleomorphic adenoma (PA) is the most common salivary gland tumor. PAs are characterized by chromosomal rearrangements of 8q12 and 12q14-15, leading to gene fusions involving the PLAG1 and HMGA2 oncogenes. Here, we performed the first comprehensive study of the transcriptomic and gene fusion landscape of 38 cytogenetically characterized PAs.
