Article Abstract
We present a sheathless, microfluidic imaging flow cytometer that incorporates stroboscopic illumination for blur-free fluorescence detection at ultra-high analytical throughput. The imaging platform is capable of multiparametric fluorescence quantification and sub-cellular localization of these structures down to 500 nm with microscopy image quality. We demonstrate the efficacy of the approach through the analysis and localization of P-bodies and stress granules in yeast and human cells using fluorescence and bright-field detection at analytical throughputs in excess of 60,000 and 400,000 cells/s, respectively. Results highlight the utility of our imaging flow cytometer in directly investigating phase-separated compartments within cellular environments and screening rare events at the sub-cellular level for a range of diagnostic applications.

Background And Purpose: Although high-resolution cone-beam computed tomography (HR-CBCT) is used for immediate evaluation of stent apposition, studies using this technique to evaluate flow diverter (FD) endothelialization during follow-up are limited. The study aims to investigate the potential of HR-CBCT in assessing FD endothelialization and identify factors influencing poor endothelialization.
Materials And Methods: The clinical and imaging data of patients with unruptured intracranial aneurysms (UIAs) treated by FDs from March 2019 to October 2023 were retrospectively analyzed.

Background: Intracranial solitary fibrous tumors (SFTs) are rare mesenchymal tumors often presenting with dural-based lesions. These tumors can exhibit aggressive characteristics with high recurrence rates and extracranial metastasis. While SFTs occasionally invade venous sinuses, cases where the tumor arises within the venous sinus are rare.

Seed dispersal through wind was historically considered a random process; however, plants can influence their dispersal through non-random seed detachment or abscission. Dandelion seeds facing the wind tend to abscise before those facing downwind, yet the mechanism that supports this has remained unclear. We measured the force needed for abscission in different directions and performed imaging of the detachment process.

Methods: For this study, 10 male dogs were enrolled, comprising 4 healthy Beagles and 6 client-owned dogs with suspected prostatic neoplasia. Computed tomography perfusion was performed in the healthy dogs using varied contrast agent doses and injection durations.
Thalamic hyperperfusion in early schizophrenia: Associations with cognitive deficits and negative symptoms.

Objective: Thalamic abnormalities have been associated with clinical and cognitive symptoms of schizophrenia, yet their role in the early stages of the disorder remain unclear. This study aimed to examine and compare thalamic perfusion differences between first-episode schizophrenia (FES) and early-course schizophrenia (ECS), along with their associations with cognitive performance and symptom severity.
Methods: This study included 100 unmedicated schizophrenia patients aged 19-30: 50 FES and 50 ECS (<5 years, ≥2 episodes).
