Fluorescent styrenes for mitochondrial imaging and viscosity sensing.

Fluorophores bearing cationic pendants, such as the pyridinium group, tend to preferentially accumulate in mitochondria, whereas those with pentafluorophenyl groups display a distinct affinity for the endoplasmic reticulum. In this study, we designed fluorophores incorporating pyridinium and pentafluorophenyl pendants and examined their impact on sub-cellular localization. Remarkably, the fluorophores exhibited a notable propensity for the mitochondrial membrane.

Imaging of mitochondria/lysosomes in live cells and .

Two rhodamine-phenothiazine conjugates, RP1 and RP2, were synthesized, and their photophysical properties, subcellular localization, and photocytotoxicity were investigated. We observed robust localization of RP1 in mitochondria and dual localization in mitochondria and lysosomes with RP2 in live cells. Live cell imaging with these probes allowed us to track the dynamics of mitochondria and lysosomes during ROS-induced mitochondrial damage and the subsequent lysosomal digestion of the damaged mitochondria.

Synbiotic Intervention Ameliorates Oxidative Stress and Gut Permeability in an In Vitro and In Vivo Model of Ethanol-Induced Intestinal Dysbiosis.

Alcoholic liver disease (ALD) alters gut microbiota and tight junctions, causing bacterial components to enter the portal vein and induce oxidative stress-induced inflammation in the liver. Only corticosteroids and liver transplants are treatment options for severe alcoholic hepatitis. ALD's pathophysiology is unknown.

Imaging of lipid droplets using coumarin fluorophores in live cells and C. elegans.

Fluorescent probes offer incredibly effective tools for visualizing the dynamic morphology of lipid droplets (LDs) and investigating their physiological interactions. In this work, we have utilized solvatochromic coumarin probes bearing nitrile and ester substituents for live-cell imaging. The fluorescence probes are characterized by a donor (diethylamino) and acceptor (nitrile and/or ester) substituents and a rotatable double bond.

Lutidine derivatives for live-cell imaging of the mitochondria and endoplasmic reticulum.

The mitochondria and endoplasmic reticulum (ER) are highly dynamic subcellular structures essential for several biological functions. The development of non-toxic, wash-free fluorophores to visualize these structures inside cells aid in understanding their localization and dynamics in diverse cellular processes. In this paper, we report the synthesis and characterization of lutidine-based cationic fluorophores bearing push-pull substituents exhibiting emission in green and red wavelength regions and their subcellular localization in living cells.

Fluorescent probes for targeting endoplasmic reticulum: design strategies and their applications.

Advances in developing organic fluorescent probes and fluorescence imaging techniques have enhanced our understanding of cell biology. The endoplasmic reticulum (ER) is a dynamic structure that plays a crucial role in protein synthesis, post-translational modifications, and lipid metabolism. The malfunction of ER contributes to several physiological and pathological conditions.

Small and medium-sized enterprises' contribution in digital technology.

Researchers have mentioned the importance of digitization in improving efficiency and productivity in Small and Medium Enterprises (SME). Fortunately, there is no proof that Digitization can be used to deal with the outcome of severe incidents like COVID-19. The research paper suggested that the increased rate of SMEs has increased significantly.

Biological seed priming mitigates the effects of water stress in sunflower seedlings.

The sunflower (Helianthus annuus L. cv. PAC 36) seedlings were inoculated with plant growth promoting rhizobacteria (PGPR), viz.
