Stress and telomere length in leukocytes: Investigating the role of GABRA6 gene polymorphism and cortisol.
Psychoneuroendocrinology
January 2025
Department of Experimental Clinical and Health Psychology, Ghent University, Ghent, Belgium. Electronic address:
Telomere length (TL) is considered a biomarker of aging, and short TL in leukocytes is related to age and stress-related health problems. Cumulative lifetime stress exposure has also been associated with shorter TL and age-related health problems, but the mechanisms are not well understood. We tested in 108 individuals whether shorter TL in leukocytes is observed in individuals with the GABRA6 TT genotype, which has been associated with dysregulation of hypothalamic-pituitary-adrenal axis activity (the main biological stress system) compared to the CC genotype.

Department of Medical Radiation Physics and Nuclear Medicine, Karolinska University Hospital, Solna, Sweden.
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.

Purpose: We compared the radiographic union and magnitude of humpback deformity correction when using different vascularized bone grafts (VBGs) and nonvascularized bone grafts (NVBGs) in the treatment of unstable scaphoid nonunions (USNUs).
Methods: This was a retrospective radiographic review of 93 patients with an USNU treated between 2013 and 2022 at a single center by a single surgeon. Inclusion criteria included skeletally mature patients with radiographic evidence of an USNU resulting from failure of either nonsurgical or operative treatment.
