Tuning the lanthanide binding tags for preferential actinide chelation: an all atom molecular dynamics study.

The present study focuses on designing mutant peptides derived from the lanthanide binding tag (LBT) to enhance selectivity for trivalent actinide (An) ions over lanthanide (Ln) metal ions (M). The LBT is a short peptide consisting of only 17 amino acids, and is known for its high affinity towards Ln. LBT was modified by substituting hard-donor ligands like asparagine (ASN or N) and aspartic acid (ASP or D) with softer ligand cysteine (CYS or C) to create four mutant peptides: M-LBT (wild-type), M-N103C, M-D105C, and M-N103C-D105C.

Counting efficiencies of shadow shield whole body counter for adult and paediatric reference computational phantoms.

Shadow Shield Whole Body Counter (SSWBC) is used to estimate internal dose of radiation workers due to the intake of fission and activation products. The SSWBC geometry was numerically modelled in FLUKA code. The computational model was validated by comparing the experimental and simulated counting efficiencies (CEs), also known as response, using Bhabha Atomic Research Centre (BARC) reference BOttle Mannequin Absorption (BOMAB) phantom.

Ambient ultraviolet-B exposure brings quantum changes in phenotypic and molecular signatures of the embryo of a high-altitude fish, Tor putitora.

Effects of environmentally relevant ultraviolet B (UVB) light on the embryonic development of a high-altitude dwelling endangered fish, Tor putitora (golden mahseer), were investigated for the first time. For that, three sets of embryos (in triplicates) were exposed to various ambient UVB light doses (1, 2 and 3 W/m, corresponding to 3.6, 7.
