Multimodal imaging of suspicious choroidal neoplasms in a primary eye‐care clinic [PDF]

Clinical and Experimental Optometry, 2017
Small suspicious choroidal neoplasms commonly present a diagnostic challenge in primary eye-care clinics, where they are most likely to present. Differentiating benign from malignant choroidal neoplasms is essential for facilitating early diagnosis and treatment, potentially decreasing the risk of metastasis and vision loss in some cases.

Intraventricular metastasis from carcinoma breast masquerading as choroid plexus neoplasm: A case report

Indian Journal of Pathology and Microbiology, 2022
Metastatic tumors in the brain represent the most common type of intracranial neoplasm, comprising 8-10% of all brain tumors. 30% of such tumors are primarily of breast origin in females. Brain parenchymal metastasis is the more common presentation. Intraventricular spread is rare, seen in less than 5% of cases in a metastatic scenario. Here, we report

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify

Caveolin‐1 Stabilizes SERCA2 to Counteract Acute Kidney Injury via Suppression of Ca2+‐Dependent Endoplasmic Reticulum Stress in Distal Tubules

Advanced Science, EarlyView.
In AKI, initial kidney injury upregulates the expression of Cav‐1, which subsequently binds to and stabilizes SERCA2 via its scaffolding domain and through deubiquitination, thereby regulating Ca2+ homeostasis and ER stress. Conversely, Cav‐1 deficiency accelerates SERCA2 degradation, triggering Ca2+ overload and ER stress, and ultimately exacerbating ...
