Purpose: To explore how blue light-emitting diode (LED) exposure affects ferritinophagy and iron homeostasis in the conjunctival epithelium. Methods: C57BL/6 J mice and human conjunctival epithelial cells were exposed ...

In this paper, a theoretical analysis and a practical study of the transient processes occurring when the LED modules are switched on are carried out. Light-emitting diode (LED) modules are a parallel, serial or mixed co...

The present study employed white (W), blue (B: 468 nm), red (R: 629 nm) and green (G: 524 nm) monochromatic LED lights for 26 days, from 11:00 to 18:00 (7 h per day), with a average of photosynthetic photon flux density ...

Improving current injection into r- and m-planes of nanowires (NWs) is essential to realizing efficient GaInN/GaN multiple quantum shell (MQS) NW-based light-emitting diodes (LEDs). Here, we present the effects of differ...

The aim of this study was to investigate the health-led growth hypothesis in selected 19 OECD countries. Therefore, in this study, different cointegration tests were applied to investigate the relationship between heal...

LED type bulb light is generally widely used in building spaces in Indonesia today because it is more energy efficient than other types. The purpose of this study is to utilize the light bulb as a new photon energy sourc...

Introduction . Inflammatory lesions and erosions of the glans penis defined as balanitis or balanoposthitis constitute a disease in which the effectiveness of conservative treatment is not sufficient. Objective. To ...

This article presents an light-emitting diode (LED) driver that actively reduces low-frequency output current ripple through a duty-cycle modulation scheme, enabling the use of compact film capacitors and eliminating ele...

BackgroundPatients with moderate-to-severe chronic obstructive pulmonary disease (COPD) have difficulty performing pulmonary rehabilitation independently. In China, resources for respiratory physicians and rehabilitation...

Abstract Background Midlife women are facing many healthcare challenges, including unmet needs in screening and preventive care. Nurse-led risk-based model in primary healthcare settings prioritizes preventive care and s...

ABSTRACT This is the protocol for a Campbell systematic review. The main objective of this project is to gather, critically appraise, and synthesize evidence about the effectiveness of government‐led communication camp...

Abstract Background Migraine is a prevalent neurological disorder and a leading cause of disability worldwide. Despite effective medications, many patients experience underdiagnosis, suboptimal medication use, and poor a...

BackgroundPatients with lymphoma frequently experience significant psychosocial burden, including anxiety, depression, and impaired quality of life, which may persist throughout the disease trajectory. Coping strategies ...

Efficient and eco-friendly disinfection of air-borne human respiratory RNA viruses is pursued in both public environment and portable usage. The AlGaN-based deep ultraviolet (DUV) light-emission diode (LED) has high prac...

With regard to micro-light-emitting diodes (micro-LEDs), their excellent brightness, low energy consumption, and ultra-high resolution are significant advantages. However, the large size of traditional inorganic phosphor...

ABSTRACT Background and Aims Atrial fibrillation (AF) is a common cardiac arrhythmia with a rising global incidence. Advances in ablation techniques have led to same‐day discharge (SDD) protocols, reducing hospital res...
