Polymorphous Indium Metal-Organic Frameworks Based on a Ferrocene Linker: Redox Activity, Porosity, and Structural Diversity.

The metallocene-based linker molecule 1,1'-ferrocenedicarboxylic acid (HFcDC) was used to synthesize four different polymorphs of composition [In(OH)(FeCHO)]. Using conventional solvent-based synthesis methods and varying the synthetic parameters such as metal source, reaction temperature, and solvent, two different MOFs and one 1D-coordination polymer denoted as CAU-43 (), In-MIL-53-FcDC_a (), and In-FcDC () were obtained. Furthermore, thermal treatment of CAU-43 () at 190 °C under vacuum yielded a new polymorph of , In-MIL-53-FcDC_b ().

C4d-negative antibody-mediated rejection with high anti-angiotensin II type I receptor antibodies in absence of donor-specific antibodies.

Aims: Acute antibody-mediated rejection can occur in absence of circulating donor-specific antibodies. Agonistic antibodies targeting the anti-angiotensin II type 1 receptor (anti-AT1 R) are emerging as important non-human leucocyte antigen (HLA) antibodies. Elevated levels of anti-angiotensin II receptor antibodies were first observed in kidney transplant recipients with malignant hypertension and allograft rejection.
