Adjunctive PCSK9 Inhibitor Evolocumab in the Prevention of Early Neurological Deterioration in Non-cardiogenic Acute Ischemic Stroke: A Multicenter, Prospective, Randomized, Open-Label, Clinical Trial.
CNS Drugs
January 2025
Department of Cardiology, Second Affiliated Hospital of Dalian Medical University, Dalian, China.
Background: Early neurological deterioration (END) is associated with a poor prognosis in acute ischemic stroke (AIS). Effectively lowering low-density lipoprotein cholesterol (LDL-C) can improve the stability of atherosclerotic plaque and reduce post-stroke inflammation, which may be an effective means to lower the incidence of END. The objective of this study was to determine the preventive effects of evolocumab on END in patients with non-cardiogenic AIS.

Clinical Trial Unit, Istituto Nazionale Tumori-IRCCS-Fondazione G. Pascale, Naples, Italy. Electronic address:
Background: The Hormonal Bone Effects (HOBOE) study tested whether adjuvant triptorelin plus either letrozole (L) or zoledronic acid (Z) plus L (ZL) was more effective than tamoxifen (T) in premenopausal patients with hormone receptor-positive (HR+) early breast cancer (BC). Here we report the long-term follow-up analysis.

An Open-Label Pilot Study to Examine the Safety, Tolerability and Efficacy of Deutetrabenazine in Isolated Dystonia.
Mov Disord Clin Pract
January 2025
Parkinson Disease and Movement Disorders Center, University of Pennsylvania, Philadelphia, Pennsylvania, USA.
Background: Dystonia may respond to VMAT2 inhibition.
Objectives: Providing pilot data on the safety, tolerability, and efficacy of deutetrabenazine in non dopa-responsive dystonia.
Methods: Deutetrabenazine was titrated by adults with isolated dystonia.
Targeting Fibroblast Activation Protein for Molecular Imaging of Fibrotic Remodeling in Pulmonary Arterial Hypertension.

The purpose of this study was to investigate the feasibility of using F-labeled fibroblast activation protein inhibitor (FAPI) PET/CT in assessing the fibrotic remodeling of the pulmonary artery (PA) and the right ventricle (RV) in pulmonary arterial hypertension (PAH). In a rat model of monocrotaline-induced PAH, rats were euthanized at different time points for tissue analysis (fibroblast activation protein immunofluorescence and Masson's trichrome staining) after completing F-FAPI PET/CT and hemodynamic measurements. Thirty-eight PAH patients were enrolled to participate in F-FAPI PET/CT imaging, with right heart catheterization and echocardiography performed within 1 wk to assess pulmonary hemodynamics and cardiac function.

Article Synopsis
- HCN ion channels play a key role in cellular activity and pain perception, with propofol acting as an analgesic by inhibiting their function.
- Researchers used a propofol analog to pinpoint binding sites on the human HCN1 isoform, revealing a specific pocket formed by certain residues in the channel.
- Mutations in this binding pocket affect propofol's ability to modulate HCN1 currents, highlighting its specific binding mechanism and offering insights for developing targeted HCN channel modulators.
