Bioactives From Brown Algae: Antioxidant, Anti‐Inflammatory, Anticancer, and Antimicrobial Potential
ChemBioEng Reviews, EarlyView.This review explores key bioactives in brown algae and their antioxidant, anti‐inflammatory, anticancer, and antimicrobial properties. Covering studies from 2014 to 2024, it highlights their relevance in pharmaceuticals, nutraceuticals, cosmetics, and foods, while addressing challenges and future directions to unlock their full potential.

Spermidine supplementation influences mitochondrial number and morphology in the heart of aged mice
Journal of Anatomy, Volume 242, Issue 1, Page 91-101, January 2023., 2023 Aging was associated with hypertrophy of left venticular myocardium in mice without an increase in mitochondrial number. Spermidine treatment increased the number of cardiomyocyte mitochondria significantly. The three‐dimensional ultrastructure of mitochondria showed signs of disarrangement in aged mice which was reduced by spermidine treatment ...

Color–Magnitude Diagram of NGC 205 and Its RR Lyrae Variables
The Astronomical JournalWe present the deepest color–magnitude diagram (CMD) for NGC 205 in the F606W (≈ V ) and F814W (≈ I ) filters. Our archival Hubble Space Telescope/Advanced Camera for Surveys field is centered ∼3 $\mathop{.}\limits^{{\rm{^{\prime} }}}$ 8 northwest of the

Popular Branchings and Their Dual Certificates [PDF]
arXiv, 2019 Let $G$ be a digraph where every node has preferences over its incoming edges. The preferences of a node extend naturally to preferences over branchings, i.e., directed forests; a branching $B$ is popular if $B$ does not lose a head-to-head election (where nodes cast votes) against any branching.

Metallicity of Globular Cluster NGC 5053 from VI CCD Photometry [PDF]
Journal of Astronomy and Space Sciences, 2001 Red giant branch shape and the luminosity of horizontal branch on the (V-I)-V CMD are used to derive the metallcity of the globular cluster NGC 5053. The metallicities of NGC 5053 derived by SMR method ([Fe/H]=-2.62+-0.07) and the relation between [Fe/H]

Detection of intergalactic red-giant-branch stars in the Virgo cluster
Nature, 1998 It has been suspected for nearly 50 years that clusters of galaxies contain a population of intergalactic stars, ripped from galaxies during cluster formation or when the galaxies' orbits take them through the cluster center. Support for the existence of such a population of free-floating stars comes from measurements of the diffuse light in clusters ...

Height process for super-critical continuous state branching process [PDF]
arXiv, 2006 We define the height process for super-critical continuous state branching processes with quadratic branching mechanism. It appears as a projective limit of Brownian motions with positive drift reflected at 0 and a>0 as a goes to infinity. Then we extend the pruning procedure of branching processes to the super-critical case.

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain
Developmental Dynamics, EarlyView.Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

Testing Tidal Theory Using Gaia Binaries: The Red Giant Branch
The Astrophysical JournalTidal interaction is a major ingredient in the theory of binary evolution. Here, we study tidal circularization in binaries with red giant primaries. We compute the tidal evolution for binaries as their primary stars evolve along the red giant branch ...
