Standard Genetic Code vs. Supersymmetry Genetic Code - Alphabetical table vs. physicochemical table.

Biosystems 2022 May 14:104695. Epub 2022 May 14.

Croatian Academy of Sciences and Arts, 10000, Zagreb, Croatia; Department of Physics, Faculty of Science, University of Zagreb, Croatia.

The fundamental role of symmetry in the genetic code is to decrease disorder between codons and to preserve the integrity of system. The Standard Genetic Code (SGC) table is structured alphabetically in a horizontal and vertical array of U-C-A-G bases only with aesthetic symmetry. We postulate "the symmetry theory of genetic code" which is based on the unique physicochemical purine - pyrimidine symmetry net between codons of our Supersymmetry genetic code (SSyGC) table.

Adv Drug Deliv Rev 2022 May 14:114344. Epub 2022 May 14.

KU-KIST Graduate School of Converging Science and Technology, Korea University, 145 Anam-ro, Seongbuk-gu, Seoul 02841, Republic of Korea; Medicinal Materials Research Center, Biomedical Research Institute, Korea Institute of Science and Technology (KIST), Hwarangno 14-gil 5, Seongbuk-gu, Seoul 02792, Republic of Korea. Electronic address:

Photodynamic nanomedicines have significantly enhanced the therapeutic efficacy of photosensitizers (PSs) by overcoming critical limitations of PSs such as poor water solubility and low tumor accumulation. Furthermore, functional photodynamic nanomedicines have enabled overcoming oxygen depletion during photodynamic therapy (PDT) and tissue light penetration limitation by supplying oxygen or upconverting light in targeted tumor tissues, resulting in providing the potential to overcome biological therapeutic barriers of PDT. Nevertheless, their localized therapeutic effects still remain a huddle for the effective treatment of metastatic- or recurrent tumors. Read More

Department of Psychology, University of Bonn, Kaiser-Karl-Ring 9, 53111 Bonn, Germany. Electronic address:

Recent advances in the neuropsychopharmacology of metacognition indicate a constituent role of glutamate for the integrity of metamnestic processes. However, the extent to which previous results can be generalized across functional domains to characterize the relationship between glutamate and metacognition remains unclear. Here, in a randomized, double-blind, placebo-controlled, preregistered fMRI study, we tested the effects of a psychotomimetic dose (target plasma concentration 100ng/mL) of the N-methyl-D-aspartate (NMDA) glutamate receptor antagonist ketamine on metacognition in a perceptual decision-making framework.
