Background: Magnesium (Mg) is a neuroprotectant in preclinical models. Lower serum Mg levels have been associated with symptomatic hemorrhagic transformation (HT) in patients with ischemic stroke. Early treatment of acute ischemic stroke with Mg may reduce rates of symptomatic HT.

This work presents a behavioral model for a microelectromechanical (MEM) relay for use in circuit simulation. Models require calibration, and other published relay models require over a dozen parameters for calibration, many of which are difficult to extract or are only available after finite element analysis. This model improves on prior work by taking advantage of model normalization, which often results in models that require fewer parameters than un-normalized models.

- Various genetic techniques help trace cell lineage during tissue development, with some focusing on spatial/temporal aspects and others linking gene expression to lineage.
- The G-TRACE system allows for quick visualization of GAL4 expression patterns, enabling genome-wide expression-based lineage studies conducted by UCLA students and high school scholars.
- Findings revealed new expression-based lineage patterns and were compiled into the G-TRACE Expression Database (GED), contributing to better student learning outcomes and retention in STEM fields.
Purpose: Percutaneous nephrolithotomy access may be technically challenging and result in significant radiation exposure. In an attempt to reduce percutaneous nephrolithotomy radiation exposure, a novel technique combining ultrasound and direct ureteroscopic visualization was developed and reviewed.
Materials And Methods: Ureteroscopy without fluoroscopy was used to determine the optimal calyx for access, which was punctured with a Chiba needle under percutaneous ultrasound guidance.
Objectives: Laparoendoscopic single-site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES) produce excellent cosmetic outcomes, but are technically challenging. The objective of this study was to test the functionality and feasibility of a novel minimally invasive surgical paradigm, which maintains triangulation but uses special externally assembled instruments to minimize the postoperative cosmetic impact.
Methods: Percutaneous Externally Assembled Laparoscopic (PEAL) instruments have specialized 2.
