Brain edema and neurological symptoms are the hallmarks of the uncommon disease known as posterior reversible encephalopathy syndrome (PRES), which can have several etiological causes. Since the etiology determines the course of treatment, diagnosis is crucial. There have only been 14 cases of PRES associated with inflammatory bowel disorders documented.

Infectious intracranial aneurysms (IIAs) are rare lesions with fragile arterial walls located within the aneurysms, carrying a high risk of rupture. Standard management often involves antibiotic therapy and parent artery occlusion; however, the latter carries a significant risk of cerebral infarction. This report presents a case of an unruptured IIA following cerebral infarction, successfully treated with coil embolization while preserving the parent artery.

Assessing the Impacts of Drug Loading and Polymer Type on Dissolution Behavior and Diffusive Flux of GDC-6893 Amorphous Solid Dispersions.

J Pharm Sci

January 2025

Department of Synthetic Molecule Pharmaceutical Sciences, Genentech, Inc., 1 DNA Way, South San Francisco, CA 94080, USA. Electronic address:

It is desirable but remains challenging to develop high drug load amorphous solid dispersions (ASDs) without compromising their quality attributes and bio-performance. In this work, we investigated the impacts of formulation variables, such as drug loading (DL) and polymer type, on dissolution behavior, diffusive flux, and in vitro drug absorption of ASDs of a high T compound, GDC-6893. ASDs with two polymers (HPMCAS and PVPVA) and various DLs (20 - 80%) were produced by spray drying and their drug-polymer miscibility was evaluated using solid-state nuclear magnetic resonance (ssNMR).

Artificial intelligence for brain neuroanatomical segmentation in magnetic resonance imaging: A literature review.

J Clin Neurosci

January 2025

Macquarie Medical School, Faculty of Medicine, Health and Human Sciences, Macquarie University, NSW, Australia; Computational NeuroSurgery (CNS) Lab, Macquarie University, NSW, Australia.

Purpose: This literature review aims to synthesise current research on the application of artificial intelligence (AI) for the segmentation of brain neuroanatomical structures in magnetic resonance imaging (MRI).

Methods: A literature search was conducted using the databases Embase, Medline, Scopus, and Web of Science, and captured articles were assessed for inclusion in the review. Data extraction was performed for the summary of the AI model used, and key findings of each article, advantages and disadvantages were identified.

When retrieved, seemingly stable memories can become sensitive to significant events, such as acute stress. The mechanisms underlying these memory dynamics remain poorly understood. Here, we show that noradrenergic stimulation after memory retrieval impairs subsequent remembering, depending on hippocampal and cortical signals emerging during retrieval.
