Ziyi Deng, Yaping Yu, Yixin Zhou, Jinhao Zhou, more

Advanced Materials > 36 > 41 > n/a - n/a

Circuits based on organic electrochemical transistors (OECTs) have great potential in the fields of biosensors and artificial neural computation due to their biocompatibility and neural similarity. However, the integration of OECT‐based circuits lags far behind other emerging electronics. Here, ternary inverters based on antiambipolar vertical OECTs (vOECTs) and their integration with the establishment...

Sri Lakshmi Chalasani, Ajinkya S. Kawale, Konstantin Akopiants, Yaping Yu, more

DNA Repair > 2018 > 68 > C > 12-24

Polynucleotide kinase/phosphatase (PNKP) has been implicated in non-homologous end joining (NHEJ) of DNA double-strand breaks (DSBs). To assess the consequences of PNKP deficiency for NHEJ of 3′-phosphate-ended DSBs, PNKP-deficient derivatives of HCT116 and of HeLa cells were generated using CRISPR/CAS9. For both cell lines, PNKP deficiency conferred sensitivity to ionizing radiation as well as to...

Biotechnology and Applied Biochemistry > 63 > 5 > 746 - 750

Two Keggin‐type polyoxometalates (POMs) containing glycine, (HGly)₃PW₁₂O₄₀ and (HGly)₄SiW₁₂O₄₀, were synthesized and evaluated as mushroom tyrosinase inhibitors. The spectrophotometric method results showed that both (HGly)₃PW₁₂O₄₀ and (HGly)₄SiW₁₂O₄₀ could strongly inhibit the diphenolase activity of the tyrosinase and that their inhibition mechanisms were reversible. Their half‐inhibition concentration...
