Altitude thresholds for hemoglobin and plasma volume regulation in adult residents of different altitudes and their impact on hemoglobin concentration

open access: yesPhysiological Reports, Volume 14, Issue 19, October 2026.
Abstract Life at altitude is characterized by increased erythropoietic activity and hemoglobin concentration ([Hb]). The first aim of the project was to identify the altitudes at which significant increases in hemoglobin mass (Hbmass) and decreases in plasma volume (PV) occur among residents living at different altitudes. The second aim was to evaluate

Oxadiazolone‐Triazole Derivatives as a New Scaffold for Modulation of Angiotensin II‐Induced Vascular Contraction

open access: yesChemMedChem, Volume 21, Issue 17, 14 September 2026.
A novel series of candidate AT1 receptor antagonists based on oxadiazolone‐triazole scaffolds was designed and synthesized. Most compounds reduced angiotensin II‐induced vascular contraction in an initial biological screening, with compound 7f emerging as the most active derivative.
