The interaction of square-planar metal complexes through space is of fundamental interest and relevant for the potential cooperative catalysis of two metal complex sites. In order to elucidate gold/gold, gold/porphyrin, and porphyrin/porphyrin interactions in the formal oxidation states +III and +II (after reduction) and in the excited triplet state after light excitation, a Pacman bis(gold(III)) complex [Au(DPD)][PF] with square-planar face-to-face gold(porphyrin) moieties has been prepared and characterized. Absorption and luminescence spectroscopy, cyclic voltammetry, and EPR spectroscopy on [Au(DPD)] and a mononuclear reference are complemented by DFT and TDDFT calculations.

- Pathogenic variants in the SLC34A1 and SLC34A3 genes, responsible for sodium-phosphate transport, lead to rare phosphate wasting conditions, primarily in children, with various clinical presentations and outcomes.
- A study analyzed data from 113 patients across 90 families, revealing distinct symptoms: SLC34A1 carriers mostly show issues in infancy, while SLC34A3 carriers experience symptoms into childhood and adulthood, including a significantly higher prevalence of chronic kidney disease in adulthood.
- Biochemical markers were similar for both groups, indicating some common underlying mechanisms, and phosphate treatment yielded partial improvements in certain enzyme levels but raised parathyroid hormone levels, suggesting a complex interaction between treatments and kidney function.
Introduction: Primary hyperoxaluria type 1 (PH1) is known for its variable clinical course, even within families. However, the extent of this heterogeneity has not been well-studied. We aimed to analyze intrafamilial clinical heterogeneity and disease course among siblings in a large cohort of familial PH1 cases.

- IgA vasculitis (IgAV) is a pediatric disease characterized by skin and systemic symptoms, and researchers conducted comprehensive studies involving genome, transcriptome, and proteome analyses on a large cohort of IgAV patients and controls to better understand the disease mechanisms.* -
- Significant associations were found with specific genetic risk factors, including two novel non-HLA loci linked to IgA receptor functioning, which may contribute to disease development through altered immune responses.* -
- Systems biology approaches helped identify key regulatory networks and master regulators in myeloid cells, along with 21 genetic loci that overlap with IgA nephropathy, suggesting shared pathways in these related conditions.*
