Postoperative visual loss is rare and most often due to posterior ischemic optic neuropathy. We describe optic nerve MR imaging of a 37-year-old man with postoperative visual loss due to posterior ischemic optic neuropathy after complicated aortic aneurysm surgery. MR demonstrated restricted diffusion and focal enhancement of both optic nerves. Combined restricted diffusion and focal enhancement is a unique MR imaging feature with postoperative vision loss.

Tigecycline (Tgc), a third-generation tetracycline is found as the last line of defense against multi-drug resistant bacteria. Recent increased rate of resistance to tgc, a human-restricted agent among animal bacteria poses a significant global health challenge. Overuse of first generation tetracyclines (Tet) and phenicols in animals have been suggested to be associated with Tgc resistance development.

This work estimates Michaelis-Menten kinetics parameters for nutrient transport under varying flow rates in the soft roots of Indian mustard () using a plant fluidic device. To find the metallic components within the roots, inductively coupled plasma mass spectrometry (ICP-MS) analysis was performed. The flow rate-dependent metabolic changes were examined using Raman spectral analysis.

Several studies explored the application of artificial intelligence (AI) in magnetic resonance imaging (MRI)-based rectal cancer (RC) staging, but a comprehensive evaluation remains lacking. This systematic review aims to review the performance of AI models in MRI-based RC staging. PubMed and Embase were searched from the inception of the database till October 2024 without any language and year restrictions.

Leptomeningeal carcinomatosis is a form of advanced metastatic disease conferring poor prognosis, most commonly associated with melanoma, small cell lung cancer, and breast cancer. In rare cases it has been shown to be associated with stroke thought to be related to vasculopathy caused by tumoral infiltration of cerebral vasculature. We present a case of acute cerebellar infarction in a patient with metastatic breast cancer complicated by leptomeningeal carcinomatosis, admitted for worsening metastatic disease.
