We investigate ultrafast (fs) electron dynamics in a liquid hydrogen sample, isochorically and volumetrically heated to a moderately coupled plasma state. Thomson scattering measurements using 91.8 eV photons from the free-electron laser in Hamburg (FLASH at DESY) show that...

Executive Functions in Healthy Older Adults Are Differentially Related to Macro- and Microstructural White Matter Characteristics of the Cerebral Lobes.

Frontiers in aging neuroscience

Hirsiger S, Koppelmans V, Mérillat S, Erdin C, Narkhede A, Brickman AM, Jäncke L.

Front Aging Neurosci. 2017 Nov 30;9:373. doi: 10.3389/fnagi.2017.00373. eCollection 2017.

Aging is associated with microstructural white matter (WM) changes. WM microstructural characteristics, measured with diffusion tensor imaging (DTI), are different in normal appearing white matter (NAWM) and WM hyperintensities (WMH). It is largely unknown how the microstructural properties of...

Congenital Pulmonary Artery Anomalies: A Review and Approach to Classification.

Journal of clinical imaging science

Hirsig LE, Sharma PG, Verma N, Rajderkar DA.
PMID: 30147993
J Clin Imaging Sci. 2018 Jul 31;8:29. doi: 10.4103/jcis.JCIS_9_18. eCollection 2018.

Congenital pulmonary artery anomalies are infrequent but given improved prenatal diagnosis and care, and neonatal surgical advances, over the past two decades are not uncommonly encountered by cardiothoracic imagers. An understanding of their etiology, classifications, associated anomalies, and surgical...

Use of levamisole-adulterated cocaine is associated with increased load of white matter lesions.

Journal of psychiatry & neuroscience : JPN

Conrad F, Hirsiger S, Winklhofer S, Baumgartner MR, Stämpfli P, Seifritz E, Wegener S, Quednow BB.
PMID: 33844483
J Psychiatry Neurosci. 2021 Apr 12;46(2):E281-E291. doi: 10.1503/jpn.200057.

BACKGROUND: Cocaine use has been associated with vascular pathologies, including cerebral white matter hyperintensities. Street cocaine is most often adulterated with levamisole, an anthelminthic drug that may also be associated with vascular toxicity. However, whether levamisole exposure from cocaine...

Juvenile granulosa cell tumor diagnosed in 6-month-old infant with precocious puberty.

Radiology case reports

Juvenile granulosa cell tumor is a rare tumor diagnosed in children, which can present with precocious puberty. We have reported a case of a 6-month-old female patient who presented with precocious puberty. Abdominopelvic imaging revealed a large mixed cystic...

Metabolic changes during periodontitis therapy assessed by real-time ambient mass spectrometry.

Clinical mass spectrometry (Del Mar, Calif.)

Bregy L, Hirsiger C, Gartenmann S, Bruderer T, Zenobi R, Schmidlin PR.

It has been shown that bacteria in periodontally diseased patients can be recognized by the detection of volatile metabolites in the headspace of saliva by real-time ambient mass spectrometry. The aim of this study was to use this detection...

Immune thrombocytopenia associated with COVID-19 mRNA vaccine tozinameran - a clinical case and global pharmacovigilance data.

We report the occurrence of immune thrombocytopenia (ITP) in a 77-year-old man a few days after receiving the first dose of the COVID-19 mRNA vaccine tozinameran (Comirnaty®). The patient was treated with systemic corticosteroids, intravenous immunoglobulins and eltrombopag. He...

A case of uterine incarceration with unrecognized uterine torsion.

Radiology case reports

Recent studies suggest that the lived environment can affect cognition across the lifespan. We examined, in a large cohort of older adults (n = 3447), whether susceptibility to a multisensory illusion, the Sound-Induced Flash Illusion (SIFI), was influenced by...
