On the Nature of the Out-of-Plane Distortions in Subporphyrins.

The field of subporphyrins has garnered great interest in recent years owing to its unique structure and associated properties. They exhibit spectroscopic features similar to porphyrins and find applications in various optoelectronic devices, photodynamic therapy etc. Most of the synthesized subporphyrins have boron coordination with an axial ligand and exhibits a bowl-shaped geometry.

Urinary tract transitional cell carcinoma and melanosis of the bladder: a case report and review of the literature.

Melanosis vesica is a rare condition and thought to be benign. We report the case of a 50-year-old man who presented with haematuria and was found to have a diffusely pigmented bladder on cystoscopy and high grade transitional cell carcinoma of his upper and lower renal tract. This required a laparoscopic nephroureterectomy and pathology confirmed a diagnosis of melanosis vesica.
