Neuroimaging methods rely on models of neurovascular coupling that assume hemodynamic responses evolve seconds after changes in neural activity. However, emerging evidence reveals noncanonical BOLD (blood oxygen level dependent) responses that are delayed under stress and aberrant in neuropsychiatric conditions. To investigate BOLD coupling to resting-state fluctuations in neural activity, we simultaneously recorded EEG and fMRI in people with schizophrenia and psychiatrically unaffected participants.

Int J Stroke
January 2025
Department of Neurology, National Center for Neurological Disorders, National Clinical Research Centre for Aging and Medicine, Huashan Hospital, State Key Laboratory of Medical Neurobiology, Fudan University, Shanghai, China.
Background: It is acknowledged that penumbra can exist beyond 24 hours after stroke onset.
Aims: The aim of this study was to explore the association between penumbral persistence at 24-72 hours and clinical outcomes in patients who did not achieve major reperfusion.
Methods: Eligible patients participating in the International Stroke Perfusion Imaging Registry with repeated 24-72 hours perfusion imaging were retrospectively included in this study.
Hypertrophic Cardiomyopathy: New Clinical and Therapeutic Perspectives of an "Old" Genetic Myocardial Disease.
Genes (Basel)

Department of Cardiac, Thoracic, Vascular Sciences and Public Health, University of Padua Medical School, 35128 Padova, Italy.
Since its first pathological description over 65 years ago, hypertrophic cardiomyopathy (HCM), with a worldwide prevalence of 1:500, has emerged as the most common genetically determined cardiac disease. Diagnostic work-up has dramatically improved over the last decades, from clinical suspicion and abnormal electrocardiographic findings to hemodynamic studies, echocardiography, contrast-enhanced cardiac magnetic resonance, and genetic testing. The implementation of screening programs and the use of implantable cardioverter defibrillators (ICDs) for high-risk individuals have notably reduced arrhythmic sudden deaths, altering the disease's mortality profile.

Faculty of Medicine, University of Kelaniya, Ragama, Sri Lanka.
Background: Cinnamon has been studied as a possible way to control blood glucose and serum cholesterol levels. However, there are no well-conducted randomized controlled trials that can accurately measure the lipid and glucose-lowering effects of Cinnamomum zeylanicum (C. zeylanicum) extract.

The combination of ultralong-acting neuromuscular block and subsequent on-demand rapid reversal may provide prolonged surgeries with improved conditions by omitting continuous or repetitive blocker administration, enabling a more stable and predictable hemodynamic profile and eliminating residual block. For this target, we prepared 19 imidazolium-incorporated tetracationic macrocycles. In vivo studies with rats revealed that one macrocycle (IMC-14) displays extremely high blocking activity.
