Objective: The aim of this experimental study was to create a new focal venous infarction model in rats.
Method: 20-male Sprague-Dawley rats were used in this experiment. Unilateral frontal strip craniectomy was done in front of the coronal suture. Frontal veins were observed by using the operative microscope. In this study we used the bipolar coagulation method over the transparent dura mater for occlusion of the bridging veins for venous infarction. Specimens were evaluated by histopathological techniques.
Results: Unilateral frontal hemispheric swelling, midline shift, brain edema, subcortical petechial hemorrhage, hemorrhagic infarction and necrosis were the histopathological findings on microscopic examination.
Conclusion: Our results revealed that the bipolar coagulation method over the transparent dura mater for occlusion of the unilateral frontal cortical veins for venous infarction might be a new experimental model in the evaluation of brain damage after disturbance to the venous circulation.

Objective: To investigate changes of brain functional activity in patients with acute unilateral vestibulopathy (AUVP) using functional magnetic resonance imaging (fMRI).
Methods: We studied 32 AUVP patients and 30 healthy controls (HC) who received resting-state fMRI scanning. Methods of voxel-based amplitude of low-frequency fluctuation (ALFF) and seed-based functional connectivity (FC) were adopted to compare the difference in brain function between the two groups.

This study aimed to evaluate changes in cerebral blood flow and perioperative outcomes in patients with unilateral symptomatic carotid artery stenosis before and after carotid artery stenting (CAS), providing insights to guide surgical decision-making. Ninety-six patients with moderate to severe unilateral symptomatic carotid artery stenosis (>50%) admitted to the Neurology Department of the Second Affiliated Hospital of Zhejiang University from June 2023 to April 2024 were included. All patients underwent CAS and magnetic resonance imaging, including diffusion-weighted imaging (DWI) and 3D quasi-continuous arterial spin-labeled perfusion imaging, within 3 days preoperatively and on the third postoperative day.

Background: The alignment of a bone-anchored prosthesis has consequences for the external moments around the residual joints and implant, and these external moments can lead to serious negative long-term effects. A clear understanding of the relationship between transtibial prosthetic alignment and external joint and implant moment for bone-anchored prosthetic users is still lacking.
Research Question: What is the effect of systematic frontal plane prosthetic alignment changes on lower limb external joint moments in people with a transtibial bone-anchored prosthesis?
Methods: Participants underwent gait analysis on an instrumented dual belt treadmill.

Silent sinus syndrome is a rare condition that typically affects the maxillary sinus, with only a few reported cases of frontal sinus involvement. Blockage of the sinus ostium leads to persistent hypoventilation, creating negative pressure and eventual sinus collapse. This report describes a previously undocumented case of facial asymmetry due to frontal silent sinus syndrome, following multiple childhood nasal injuries.
