Objectives: This experimental study compares the precision and surgical outcomes of manual versus robotic electrode insertions in cochlear implantation.
Methods: Conducted on formalin-fixed cadaveric heads, the study involved nine senior neurotologists performing both manual and robotic insertions.
Results: The results showed no statistically significant difference between the two methods in insertion angle, cochlear coverage, or electrode coverage.
Background: While magnetic resonance imaging (MRI) remains the gold standard for morphological imaging, its ability to differentiate between tumor tissue and treatment-induced changes on the cellular level is insufficient. Notably, glioma cells, particularly glioblastoma multiforme (GBM), demonstrate overexpression of chemokine receptor-4 (CXCR4). This study aims to evaluate the feasibility of non-invasive Ga-Cixafor™ PET/CT as a tool to improve diagnostic accuracy in patients with high-grade glioma.

Article Synopsis
- Land subsidence has become a growing issue globally, particularly in developing countries like Iran, where excessive groundwater extraction for agriculture is a major factor.
- In Nourabad, Fars province, different farming methods such as dry farming, irrigated farming, and summer crops farming significantly impact subsidence rates, with rice farming leading to the highest subsidence at about 10 cm per year.
- The study utilized satellite images and advanced data analysis techniques, revealing a strong correlation between groundwater extraction and land subsidence, marking a critical need for sustainable agricultural practices to conserve water resources.
Article Synopsis
- Cochlear implantation is a leading treatment for severe hearing loss, and the study focuses on improving the process through Robotically Assisted Cochlear Implantation Surgery (RACIS) using a method named HEARO for precise inner ear access.
- A preclinical study using cadavers showed high accuracy in the surgical technique, with a successful insertion rate of 94% and no damage to critical structures like the facial nerve.
- Future developments for RACIS will enhance the surgical process with features like haptic feedback, automated trajectory planning, and improved imaging technology for better outcomes.
The synthesis and stabilization of Pd nanoclusters on a support, as well as simultaneously achieving optimal catalytic activity, remain challenging tasks. Functionalizing the support surface with specific ligands offers a promising solution, but it often requires carefully balancing trade-offs between the reaction yield and catalyst stability. Here, we used two different ligands (propylamine and propylthiol) to functionalize the layered silicate's interlayer surface for Pd nanocluster synthesis and stabilization.
