Move beyond free radical theory of aging
iMetaOmics, EarlyView.Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 Beta-carotene pigment was extracted from 6 strains collected from different sources related to some species of the genus Rhodotorula sp. The maximum productivity was in the strain Rhodotorula mucilaginosa BA61 with amount 10.25 gm/l. The minimum productivity was from the strain R. minuta BA78 with amount 5.39 gm/l. The effects of the chemical mutagen (

Understanding/unravelling carotenoid excited singlet states. [PDF]
, 2018 Carotenoids are essential light-harvesting pigments in natural photosynthesis. They absorb in the blue–green region of the solar spectrum and transfer the absorbed energy to (bacterio-)chlorophylls, and thus expand the wavelength range of light that is ...

Coordination Effect of Oligopolists' Multimarket Contact
International Studies of Economics, EarlyView.ABSTRACT In this article, we examine the coordination effect of oligopolists' multimarket contact with asymmetric cost. We extend a model of infinitely repeated multimarket contact games with “symmetric advantage” in the seminal paper of Bernheim and Whinston (The RAND Journal of Economics 1990; 21(1): 1–26).

Bioconversion of plant wastes to β-carotene by Rhodotorula glutinis KU550702
European Journal of Biological Research, 2016 Microbial synthesis of β-carotene has gained more interest as an alternative to synthetic β-carotene due to easy extraction and high yield. The vitamin microbial production is mainly dependent on culture conditions and the medium compositions.
