Rhodium-mediated Assembly of New Heterocycles: From Borylenes to Oxaboroles.

Base-stabilized rhodium borylene complex κ-L(CO)Rh(BMes), 2; κ-L=κ-NN'-Rh,κ-N-B-(2,5-[PrP=N(4-PrCH)]-N'(CH)); Mes=mesityl, reacts with a series of alkynes (PhC≡C-R; R=Ph, Me, COEt, H) to yield unique structures whereby the alkyne has regioselectively added across boron and the carbon atom of a CO ligand. The resulting complexes, LRh[C(O)C(Ph)C(R)B(Mes)], 3, react with additional CO to afford cycle-containing products, L(CO)Rh ), 5, that ultimately release highly functionalized organic heterocycles of the form =NPipp (Pipp=4-PrCH), 6. These oxaboroles, which were assembled from a primary hydroborane, CO, an alkyne, and an azide-generated NPipp, are structurally analogous to two of the five boron-containing therapeutics approved by the FDA.

Product innovation of non-alcoholic barley-based teas and kombucha: Consumer preferences and emotional responses.

This research explores consumer preferences and emotional reactions to beverages made from roasted barley and examines the possibility of launching a new product line featuring Streaker barley grown in the Pacific Northwest. Utilizing hedonic scales, just-about-right scales, and check-all-that-apply questions, a sensory evaluation was conducted. The study reveals two distinct consumer clusters, each exhibiting contrasting preferences and responses to novel beverages incorporating Streaker barley.

Safety and immunogenicity of the ChAdOx1-MVA-vectored conserved mosaic HIVconsvX candidate T-cell vaccines in HIV-CORE 005.2, an open-label, dose-escalation, first-in-human, phase 1 trial in adults living without HIV-1 in the UK.

Background: An HIV-1 vaccine is long overdue. Although vaccine research focuses on the induction of broadly neutralising antibodies, challenging infections such as HIV-1 could require parallel induction of protective T cells. It is important to recognise that not all T cells contribute to protection equally.

Politics, policy and action: lessons from rural GP advocacy in Ireland.

Context: Ireland has one of the most rural populations in Europe. Rurality presents challenges when accessing health services but should not be perceived as problematic and in need of a structural fix. Structural urbanism where health care is viewed as a commodity for individuals, rather than an infrastructure for populations, innately favours larger urban populations and has detrimental outcomes for rural health.
