Self-assembly of α-D nucleosides to supramolecular hydrogels is described in detail. Hydrogel formation was studied on α-D 2'-deoxyguanosine (α-dG), and the fluorescent 8-azapurine α-D nucleosides 2-amino-8-aza-2'-deoxyadenosine (α-2-NH2-z8Ad) and 8-aza-2'-deoxyisoguanosine (α-z8iGd). These compounds were prepared from α-D 8-aza-2'-deoxyguanosine by an activation/amination protocol followed by deamination.

Objectives: The aim of this retrospective study was to collect epidemiological, clinical, laboratory, imaging, management, and follow-up data on cases of alveolar echinococcosis (AE) diagnosed and/or followed up within the Namur Hospital Network (NHN) in order to gather information on the challenges, pitfalls, and overall experience in the diagnosis and treatment of AE.

Methods: EchiNam was a multicenter retrospective study. Patients diagnosed and/or treated for probable or confirmed AE in the NHN between 2002 and 2023 were included in the study.

7-Deaza-2'-deoxyisoguanosine forms stable inverse Watson-Crick base pairs with 5-methyl-2'-deoxyisocytidine and purine-purine base pairs with 2'-deoxyguanosine or 5-aza-7-deaza-2'-deoxyguanosine. Both base pairs expand the genetic coding system. The manuscript reports on the functionalization of these base pairs with halogen atoms and clickable side chains introduced at 7-position of the 7-deazapurine base.

Article Synopsis
  • The manuscript discusses the synthesis of 7-deazapurine and pyrimidine nucleoside cycloadducts created through the inverse electron demand Diels-Alder (iEDDA) reaction with a specific 3,6-di(pyrid-2-yl)-1,2,4,5-tetrazine compound.
  • Experimental findings show that the addition of spacer units between nucleobases and pyridazine cycloadducts enhances the stability of DNA duplexes, while direct connections diminish stability.
  • The study also highlights the significance of oxidation in reactions involving alkenyl compounds and the impact of synthesized oligonucleotides on mismatch formation, indicating that linkers can help reduce errors in certain interactions with

Background: There are calls worldwide for the mainstreaming of genetic testing in breast cancer (BC) clinics, but health care professionals (HCPs) are not always familiar with nor confident about genetic counselling. TRUSTING (Talking about Risk & uncertainties of Testing in Genetics is an educational programme shown to significantly improve HCPs' knowledge, communication, self-confidence, and self-awareness. We rolled out TRUSTING workshops across the UK and probed their influence on mainstreaming within BC clinics.
