Multifunctional luminogens with synergy of aggregation-induced delayed fluorescence, two-photon absorption and photocurrent generation.

In this study, we investigated the aggregation-induced delayed fluorescence (AIDF) properties of three luminogens - TN, TA, and TP. Our comprehensive theoretical analysis reveals a significant reduction in the Δ in their aggregated or solid-state, activating TADF, on a ∼μs time-scale. Additionally, these luminogens demonstrate two-photon excited anti-Stokes photoluminescence emission and improved photocurrent generation, attributed to their strong charge transfer characteristics and longer singlet exciton lifetimes.

An insight into COVID-19 host immunity at single-cell resolution.

Host immunity helps the body to fight against COVID-19. Single-cell transcriptomics has provided the scope of investigating cellular and molecular underpinnings of host immune response against SARS-CoV-2 infection at high resolution. In this review, we have systematically described the virus-induced dysregulation of relative abundance as well as molecular behavior of each innate and adaptive immune cell type and cell state during COVID-19 infection and for different vaccinations, based on single-cell studies published in last three-four years.

Raman Imaging of Targeted Drug Delivery with DNA-Based Nano-Optical Devices.

Raman spectroscopy (RS) has emerged as a novel optical imaging modality by identifying molecular species through their bond vibrations, offering high specificity and sensitivity in molecule detection. However, its application in intracellular molecular probing has been limited due to challenges in combining vibrational tags with functional probes. DNA nanostructures, known for their high programmability, have been instrumental in fields like biomedicine and nanofabrication.

Peripheral Ameloblastoma Resembling an Exophytic Gingival Lesion: A Report of a Rare Case.

Peripheral ameloblastoma is a rare, benign, slow-growing odontogenic neoplasm prevalent in the mandible. It originates from the odontogenic epithelium and its remnants, and its histological characteristics are identical to those of intraosseous ameloblastoma. It is less aggressive and invasive than its intraosseous variety, with a low recurrence rate.

Zebrafish navigating the metabolic maze: insights into human disease - assets, challenges and future implications.

Zebrafish () have become indispensable models for advancing our understanding of multiple metabolic disorders such as obesity, diabetes mellitus, dyslipidemia, and metabolic syndrome. This review provides a comprehensive analysis of zebrafish as a powerful tool for dissecting the genetic and molecular mechanisms of these diseases, focusing on key genes, like , , , and . Zebrafish offer distinct advantages, including genetic tractability, optical transparency in early development, and the conservation of key metabolic pathways with humans.
