Background: The increased demand for anti-aging treatments over the past decade has fueled the development of multimodality devices. This allows for more efficacious treatment of dermal defects, excess adiposity, and skin laxity. Radiofrequency (RF) devices are constantly evolving and consequently adding multiple indications for their use. In this article, the authors focus on bipolar and multipolar RF modalities.

Objective: The objective was to review, summarize, and evaluate the key studies of procedural therapies using bipolar and multipolar RF technologies.

Methods: Studies selected for evaluation had clear statements of purpose, patient selection, follow-up evaluations, previous and concurrent medications, treatment parameters, methods for evaluating results, and adverse effects. All studies were complete and published in peer-reviewed journals.

Results And Conclusion: With their unique mechanism of action, bipolar and multipolar RF devices remain versatile treatment options associated with minimal downtime and pain compared with monopolar RF and other nonablative modalities. Proper patient selection and education along with an experienced treating physician is crucial in achieving patient satisfaction and results. It is important that larger studies are conducted to provide data on upcoming devices. Review of the literature provides a starting point for physicians seeking to treat patients safely and effectively with newer devices.

Cell-autonomous action of in radial migration of cortical projection neurons.

Front Mol Neurosci

December 2024

State Key Laboratory of Optometry, Ophthalmology and Vision Science, School of Ophthalmology and Optometry and Eye Hospital, Wenzhou Medical University, Wenzhou, China.

Neuronal radial migration is a fundamental process for cortical development, the disruption of which causes neurological and psychiatric dysfunctions. SLIT2 plays diverse functions in brain development and is a well-known axon guidance molecule. In this study, we investigated the radial migration of projection neurons in the developing cerebral cortex by knockdown (KD) of in mice.

Introduction: Differences in predictability of ablation success for premature ventricular contractions (PVCs) between earliest isochronal map area (EIA), local activation time (LAT) differences on unipolar and bipolar electrograms (⊿LAT), LAT prematurity on bipolar electrograms (LAT), and unipolar morphology of QS or Q pattern remain unclear. We verified multiple statistical predictabilities of those indicators of ablation success on mapped cardiac surface.

Methods: Thirty-five patients with multiple PVCs underwent catheter ablation after LAT mapping using multipolar mapping catheters with unipolar-based annotation.

Neurite initiation from newly born neurons is a critical step in neuronal differentiation and migration. Neuronal migration in the developing cortex is accompanied by dynamic extension and retraction of neurites as neurons progress through bipolar and multipolar states. However, there is a relative lack of understanding regarding how the dynamic extension and retraction of neurites is regulated during neuronal migration.

Unipolar voltage electroanatomic mapping detects structural atrial remodeling identified by LGE-MRI.

Heart Rhythm

October 2024

Department of Biomedical Engineering, Johns Hopkins University, Baltimore, Maryland; Alliance for Cardiovascular Diagnostic and Treatment Innovation, Johns Hopkins University, Baltimore, Maryland. Electronic address:

Background: In atrial fibrillation (AF) management, understanding left atrial (LA) substrate is crucial. While both electroanatomic mapping (EAM) and late gadolinium enhancement magnetic resonance imaging (LGE-MRI) are accepted methods for assessing the atrial substrate and are associated with ablation outcome, recent findings have highlighted discrepancies between low-voltage areas (LVAs) in EAM and LGE areas.

Objective: The purpose of this study was to explore the relationship between LGE regions and unipolar and bipolar LVAs using multipolar high-density mapping.

Centrosome amplification (CA), an abnormal increase in the number of centrosomes in the cell, is a recurrent phenomenon in lung and other malignancies. Although CA promotes tumor development and progression by inducing genomic instability (GIN), it also induces mitotic stress that jeopardizes cellular integrity. CA leads to the formation of multipolar mitotic spindles that can cause lethal chromosome segregation errors.
