32P-Postlabeling analysis of IQ, MelQx and PhIP adducts formed in vitro in DNA and polynucleotides and found in vivo in hepatic DNA from IQ-, MelQx- and PhIP-treated monkeys [PDF]
, 1993 The P-32-postlabeling method was used to examine the adducts in DNA, polynucleotides, and mononucleotides reacted in vitro with the N-hydroxy and N-acetoxy derivatives of 2-amino-3-methylimidazo[4,5-f]quinoline (IQ), 2-amino-3, 8-dimethylimidazo[4,5-f ...

Journal of Biogeography, EarlyView.ABSTRACT Aim During glacial periods, highly mobile species often shifted to warmer, ice‐free regions known as refugia, which frequently maintained higher genetic diversity than newly colonised areas after glacial retreat. We analyse complete mitogenome sequences from 11 killer whale samples in Nemuro Strait to test the hypothesis that waters around ...

Adsorption of Nucleic Acid Bases, Ribose, and Phosphate by Some Clay Minerals
Life, 2015 Besides having a large capacity for taking up organic molecules, clay minerals can catalyze a variety of organic reactions. Derived from rock weathering, clay minerals would have been abundant in the early Earth. As such, they might be expected to play a

A Chromosome Inversion Creates a Supergene for Sex and Colour in Lake Malawi Cichlids
Molecular Ecology, EarlyView.ABSTRACT Cichlid fishes have the highest rates of evolutionary turnover of sex chromosomes among vertebrates. Many large structural polymorphisms in the radiation of cichlids in Lake Malawi are associated with sex chromosomes and may also carry adaptive variation.

pH-Sensitive Chitosan–Heparin Nanoparticles for Effective Delivery of Genetic Drugs into Epithelial Cells [PDF]
, 2019 Chitosan has been extensively studied as a genetic drug delivery platform. However, its efficiency is limited by the strength of DNA and RNA binding.

Plant, Cell &Environment, EarlyView.ABSTRACT Deep sequencing of ribosome footprints, also known as ribosome profiling (Ribo‐seq), enables the quantification of mRNA translation and a comprehensive view of the translatome landscape. Here, we report an optimised Ribo‐seq protocol and analysis pipeline for the model green alga, Chlamydomonas reinhardtiii (Chlamydomonas).

Molecules, 2012 We report herein the synthesis and characterization of 9-(2-diallylaminoethyl) adenine. We evaluated two different synthetic routes starting with adenine where the optimal route was achieved through coupling of 9-(2-chloroethyl)adenine with diallylamine.

Chemical Switching: A Concept Inspired by Strategies from Biocatalysis and Organocatalysis
ChemBioChem, Volume 26, Issue 11, June 3, 2025.Chemical Switching is introduced as a novel technology that exploits the promiscuity of enzymatic transformations by applying small molecule organocatalytic switches (ORCAs) or gain‐of‐function protein variants. The modulation of underlying chemical principles thereby amplifies low‐rate or installs otherwise absent enzymatic activities to dominate ...
