A High-Performance Isolated SEPIC Converter for Non-Electrolytic LED Lighting

IEEE Access, 2021
This paper proposes a high-performance isolated single-ended primary inductor converter (SEPIC) that is integrated with a non-dissipative snubber for a light-emitting diode (LED) driver. The proposed LED driver employs the snubber circuit to minimize any

Non‐motor phenotypic subgroups in adult‐onset idiopathic, isolated, focal cervical dystonia

Brain and Behavior, 2021
Background: Non‐motor symptoms are well established phenotypic components of adult‐onset idiopathic, isolated, focal cervical dystonia (AOIFCD). However, improved understanding of their clinical heterogeneity is needed to better target therapeutic ...

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

Myocardial infarction in isolated ventricular non-compaction: Contrast echo and MRI

, 2006
We describe the case of an occasional discovery of isolated ventricular non-compaction in an adult recovered for an acute myocardial infarction, in which only the echocardiogram revealed an isolated ventricular non-compaction, confirmed by MRI: an ...
