AI Article Synopsis

  • Deep penetrating nevus (DPN) is a rare type of skin lesion that can be mistaken for malignant melanoma due to its dark pigmentation.
  • It is typically found in young adults and often appears on areas like the face, neck, or shoulder.
  • A case study involved a 60-year-old woman with a long-standing mole on her arm, which was initially thought to be a compound nevus but was ultimately diagnosed as DPN after a biopsy.

Article Abstract

Deep penetrating nevus (DPN) is a variant of melanocytic nevus which goes unrecognized due to its relative rarity and may be misinterpreted as malignant melanoma. It commonly presents in young adults as a dark pigmented lesion on the face, neck, or shoulder. A 60-year-old lady presented with a mole over the left arm of 8 years duration. A biopsy of the lesion was performed under the clinical impression of a compound nevus with suspicion of malignancy. Based on the histologic features, a diagnosis of DPN was put forward.

Photodynamic antimicrobial therapy with Erythrosin B, Eosin Y, and Rose Bengal for the inhibition of fungal keratitis isolates: An in vitro study.

Introduction: Fungal keratitis is a leading cause of corneal blindness, with current antifungal treatments having limited efficacy. One promising treatment modality is Rose Bengal (RB) photodynamic antimicrobial therapy (PDAT) that has shown mixed success against fungal keratitis. Therefore, there is a need to explore the antimicrobial efficacy of other green-light activated photosensitizers that have deep penetration in the cornea to combat the deep fungal infections, such as Erythrosin B (EB) and Eosin Y (EY).

Soft Metalens for Broadband Ultrasonic Focusing through Aberration Layers.

Nat Commun

January 2025

Key Laboratory of Underwater Acoustic Communication and Marine Information Technology of the Ministry of Education, College of Ocean and Earth Sciences, Xiamen University, Xiamen, China.

Aberration layers (AL) often present significant energy transmission barriers in microwave engineering, electromagnetic waves, and medical ultrasound. However, achieving broadband ultrasonic focusing through aberration layers like the human skull using conventional materials such as metals and elastomers has proven challenging. In this study, we introduce an inverse phase encoding method employing tunable soft metalens to penetrate heterogeneous aberration layers.

Purpose: This study aimed to identify a novel recombinant adeno-associated virus (rAAV) capsid variant that can widely transfect the deep retina through intravitreal injection and to assess their effectiveness and safety in gene delivery.

Methods: By adopting the sequences of various cell-penetrating peptides and inserting them into the capsid modification region of AAV2, we generated several novel variants. The green fluorescent protein (GFP)-carrying variants were screened following intravitreal injection.

Neuronal Tracing and Visualization of Nerve Injury by a Membrane-Anchoring Aggregation-Induced Emission Probe.

ACS Nano

January 2025

Clinical Translational Research Center of Aggregation-Induced Emission, School of Medicine, The Second Affiliated Hospital, School of Science and Engineering, The Chinese University of Hong Kong, Shenzhen (CUHK-Shenzhen), Shenzhen 518172, P. R. China.

Deciphering neuronal circuits is pivotal for deepening our understanding of neuronal functions and advancing treatments for neurological disorders. Conventional neuronal tracers suffer from restrictions such as limited penetration depth, high immunogenicity, and inadequacy for long-term and imaging. In this context, we introduce an aggregation-induced emission luminogen (AIEgen), MeOTFVP, engineered for enhanced neuronal tracing and imaging.

Foreign body ingestion is a problem that commonly presents in almost all otolaryngologic practices. However, less commonly do those foreign bodies perforate, migrate to, and impact the soft tissue of the neck while nearly invading the carotid sheath that accommodates the major neurovascular supply of the head. We report the case of a patient who had radiologic evidence of foreign body impaction and required neck exploration through an external approach to retrieve a crab leg embedded far within the deep cervical fascia.
