Yellow dots are follicular ostium filled with keratin and/or sebum. Initially, they were exclusively associated with alopecia areata. Currently they have also been described in androgenetic alopecia, chronic cutaneous (discoid) lupus erythematosus, and dissecting cellulitis. Due to the growing importance of trichoscopy and its findings in the evaluation of the scalp, this article describes the main diseases in which yellow dots are a common trichoscopic finding, highlighting its characteristics in each dermatosis.

Blue honeysuckle (Lonicera caerulea L.) has been widely used in food, medicine, health products, cosmetics, materials, and other products. Between September 2022 and September 2023, a leaf spot disease was observed on approximately 20% of blue honeysuckle plants of the 'Lanjingling' cultivar grown in a 0.

Benign yellow dot maculopathy (BYDM) is a recently described rare, asymptomatic, early onset, and non-progressive macular phenotype. It is characterized by the presence of multiple white-yellow dots encircling the fovea, which are hyperautofluorescent on fundus autofluorescence. Here, we expand on the few reports available by presenting a case series of five Portuguese patients with clinical BYDM phenotype and congruent multimodal imaging, including the second reported unilateral case.

High-performance, environmentally friendly indium phosphide (InP)-based quantum dots (QDs) are urgently needed to meet the demands of rapidly evolving display and lighting technologies. By adopting the highly efficient and cost-effective one-pot method and utilizing aluminum isopropoxide (AIP) as the Al source, a series of Al-doped InP/(Al)ZnS QDs with emission maxima ranging from 480 to 627 nm were synthesized. The photoluminescence quantum yield (PLQY) of the blue, green, yellow, orange, and red QDs, with emission peaks at 480, 509, 560, 600, and 627 nm, reached 34%, 62%, 86%, 96%, and 85%, respectively.

Developing hybrid fluorescence (FL)/room-temperature phosphorescent (RTP) materials in dry-state, aqueous, and organic solvents holds paramount importance in broadening their applications. However, it is extremely challenging due to dissolved oxygen and solvent-assisted relaxation causing RTP quenching in an aqueous environment and great dependence on SiO-based materials. Herein, an efficient endogenetic carbon dot (CD) strategy within melamine-formaldehyde (MF) microspheres to activate RTP of CDs has been proposed through the pyrolysis of isophthalic acid (IPA) molecules and branched-chain intra-microspheres.
