Debating tRNA Origins.

J Mol Evol

Biology Department, Boston College, Chestnut Hill, MA, USA.

Published: April 2020

The tRNA is a critical component in all modern translation systems as well as an important intermediate in models of early protein coding systems. In the following works, proponents for each of the major hypotheses for tRNA origin and evolution engage in discussion of the merits for each model.

The potential association of milk with childhood obesity has been widely debated and researched. Milk is known to contain many bioactive compounds as well as bovine exosomes rich in micro-RNA (miR) that can have effects on various cells, including stem cells. Among them, adipose stem cells (ASC) are particularly interesting due to their role in adipose tissue growth and, thus, obesity.

Based on the nucleotide sequences of the mitochondrial genome (mitogenome) of specimens taken from two mussel species ( and ), an investigation was performed by means of the complex approaches of the genomics, molecular phylogenetics, and evolutionary genetics. The mitogenome structure of studied mussels, like in many other invertebrates, appears to be much more variable than in vertebrates and includes changing gene order, duplications, and deletions, which were most frequent for tRNA genes; the mussel species' mitogenomes also have variable sizes. The results demonstrate some of the very important properties of protein polypeptides, such as hydrophobicity and its determination by the purine and pyrimidine nucleotide ratio.

Article Synopsis
  • The study investigates the optimal timing for intubating COVID-19 patients and the effectiveness of high-flow nasal cannula (HFNC) therapy, focusing on failure rates associated with delayed treatment.
  • Researchers analyzed data from 122 patients, finding that 13.9% experienced HFNC failure, with significant differences in initial oxygenation levels between failure and non-failure groups.
  • The study identifies a 10% increase in lactate dehydrogenase (LDH) and interleukin (IL)-6 levels, along with persistent SARS-CoV-2 RNAemia, as indicators of higher risk for HFNC failure, emphasizing the importance of early intervention.
