Patient signalment and aetiology of hypercortisolism in Australian dogs with Cushing's syndrome.

Objective: Patient characteristics of Cushing's syndrome differ between countries and have not been assessed in the Australian dog population. This study describes signalment and distribution of adrenocorticotropic hormone (ACTH)-dependent hypercortisolism (ADH) and ACTH-independent hypercortisolism (AIH) in Australian dogs.

Animals: Two-hundred client-owned dogs that had endogenous ACTH concentrations measured by radioimmunoassay.

Enhancing CO Capture via Metal-Ligand Cooperativity: Tuning Ligand Basicity and Zn(II) Lewis Acidity.

A series of thiosemicarbazonato-hydrazinatopyridine zinc(II) complexes were evaluated as direct air CO capture agents. The complexes sequester CO in a methanol solution as a metal-coordinated methylcarbonate. The reaction is reversible upon sparging of solutions with an inert gas (N or Ar).

Metal-Ligand Cooperativity Promotes Reversible Capture of Dilute CO as a Zn(II)-Methylcarbonate.

In this study, a series of thiosemicarbazonato-hydrazinatopyridine metal complexes were evaluated as CO capture agents. The complexes incorporate a non-coordinating, basic hydrazinatopyridine nitrogen in close proximity to a Lewis acidic metal ion allowing for metal-ligand cooperativity. The coordination of various metal ions with (diacetyl-2-(4-methyl-thiosemicarbazone)-3-(2-hydrazinopyridine) (HL) yielded ML (M = Ni(II), Pd(II)), ML(CHOH) (M = Cu(II), Zn(II)), and [ML(PPh)]BF (M = Co(III)) complexes.
