This article studies the understanding of acid and base concepts of the 3rd-grade students in middle school. An effective teaching strategy for improving their acid and base concepts was designed by considering students' prior knowledge using Lawson's learning cycle method. The control group was ada...
Grade: Technical 4.11 Protective Equipment and Clothing SRP: When working with strong solutions of acids or bases or other caustic or corrosive materials, always wear a full face mask. When working with caustic or corrosive gases or vapors, a full face mask will not protect the eyes or prevent...
C. Justin Raj, in Biosensors and Bioelectronics, 2019 3.1 Nucleic acid-based dengue biosensor Nucleic acid such as DNA or RNA fragments are commonly used as biorecognition elements in dengue biosensor. It relies on either complementary base-pairing between the immobilized nucleic acid sequence and ...

Gene functional annotation was based on blastp searches of KOG, TrEMBLe, Swissprot, GO, KEGG, PFAM, NR and CDD databases, and manually revised by comparisons with homologous genes in the NCBI database (https://www.ncbi.nlm.nih.gov/). All the predicted genes were used to construct a ...
In addition, proteins with domain structures identical to that of TAS1 were also found in other fungal species from the National Center for Biotechnology Information database, which suggests that this type of hybrid enzyme is distributed in Ascomycota and Basidiomycota fungi (Supplementary Table 2)....
To fabricate such multi- functional catalysts, multi-components are usually needed comprising of noble metals Pt, Au, Pd or Ru and acids or bases through loading these metal nanoparticles on probable acid or base supports5. Because of the increasing interest for developing cascade reactions in ...

(52 days after the first dose), then gradually decreased and returned to baseline levels at month 12. This participant experienced grade 1 or 2 IRRs during the infusions of 11/43 (25.6%) doses received. The participant continued receiving mRNA-3927 and has not experienced IRRs for more...
Moreover, leukaemic asparaginase resistance is associated with elevated ASNS expression4, and ASNS expression in solid tumours correlates with tumour grade and poor prognosis5. Recently, genetic silencing of ASNS in sarcoma cells combined with depletion of plasma asparagine levels via asparaginase was ...
