Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Morphology and Structure of Carbon Films Deposited at Varying Chamber Pressures

open access: yes, 2020
Depositing thin and thick films through different types of deposition units is a topic of great interest. In deposition chamber, each synthesis is carried out at some value of chamber pressure. In addition to different gases, photon energy also exists in

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

open access: yesFEBS Letters, EarlyView.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Limited impact of within-vector ecology on the evolution of malaria parasite transmission investment

open access: yesFrontiers in Malaria
Malaria parasites spend part of their life in a vertebrate host and the rest in an arthropod vector and must successfully navigate both environments to gain fitness.

Mitochondrial fatty acid oxidation is stimulated by red light irradiation

open access: yesFEBS Letters, EarlyView.
Light at different wavelengths has distinct effects on keratinocyte viability and metabolism. UVA light abrogates metabolic fluxes. Blue and green light have no effect on metabolic fluxes, while red light enhanced oxidative phosphorylation by promoting fatty acid oxidation. Keratinocytes are the primary constituents of sunlight‐exposed epidermis.

The effects of supplemental feeds containing different protein: Energy ratios on the growth and survival of Tilapia nilotica (Oreochromis niloticus) in brackishwater ponds [PDF]

open access: yes, 1985
A research was conducted in thirty approximately 100 sq.m earthern ponds of the Brackishwater Aquaculture Centre (BAC), College of Fisheries, University of the Philippines, Leganes Iloilo from November 7, 1982 to March 7, 1983 to evaluate the effects of ...

Vacuolar transport and function of Saccharomyces cerevisiae sterol ester hydrolase Tgl1

open access: yesFEBS Letters, EarlyView.
Tgl1, one of yeast sterol ester hydrolases, had been found on the lipid droplets where sterol esters are mainly stored. This study revealed that Tgl1 is transported into the vacuole depending on the ESCRT‐I–III complex, and that it exhibits intra‐vacuolar sterol ester hydrolase activity.

An investigation into catalysts to improve the low temperature performance of an SCR [PDF]

open access: yes, 2009
Selective catalytic reduction with NH3 is considered as one of the most effective technologies controlling NOx emission. Metal Fe based catalysts were used in the investigation to improve the low temperature performance of NOx conversion. The temperature
