Intramedullary schwannomas in the conus medullaris are very rare and are usually not associated with syringomyelia. We report a unique case of intramedullary schwannoma in the conus medullaris with long-segment syringomyelia. The patient was a 60-year-old male, initially presenting with left dorsalgia, subsequently developing weakness in the right lower extremity.

Submicron ultrasound contrast agents hold great potential to extend the bubble-mediated theranostics beyond the vasculature, but their acoustic response and the interaction effects between them remain poorly understood. This study set out to numerically examine the interaction effects on the subharmonic oscillations of nanobubbles and the resultant acoustic emissions under subharmonic resonance conditions. Results showed that a negative correlation between bubble size and subharmonic resonance frequency is readily obtained from the radius response curves.

Department of Endocrinology, Shandong Provincial Hospital, Shandong University, Shandong Provincial Hospital Affiliated to Shandong First Medical University, Jinan, Shandong, China.
Background: Rare endocrine diseases (RED) often pose chronic and life-threatening challenges, yet their economic costs and societal impact remains have not been precisely quantified.
Methods: We obtained patient data from the 2018 Nationwide Inpatient Sample (NIS) and the Nationwide Readmissions Database (NRD), identifying RED patients through International Classification of Diseases, 10th revision codes. The difference of economic burden between RED patients and the control group, including hospital length of stay, hospitalisation costs, and readmission rates, was assessed using chi-square tests.

The prion phenotype in yeast manifests as a white, pink, or red color pigment. Experimental manipulations destabilize prion phenotypes, and allow colonies to exhibit (red) sectored phenotypes within otherwise completely white colonies. Further investigation of the size and frequency of sectors that emerge as a result of experimental manipulation is capable of providing critical information on mechanisms of prion curing, but we lack a way to reliably extract this information.

BMJ Open
November 2024
Rural Clinical School, Faculty of Medicine, The University of Queensland, Toowoomba, Queensland, Australia.
Objective: The impact of COVID-19 on medical students has predominantly been assessed by one-off survey studies at the pandemic onset. This national study investigated the sustained impacts of the COVID-19 pandemic on medical students' rural clinical placement learning and well-being.
Design: Repeated cross-sectional survey design.
