Background and Purpose Dipeptidyl peptidase 4 (DPP-4) inhibitors are a class of oral glucose-lowering drugs used in the treatment type 2 diabetes. In pilot study using human kidney biopsies, we observed high DPP-4 expression early crescent formation. This glomerular lesion occurs different diseases is hallmark pathogenesis renal dysfunction. Therefore, investigated potential involvement nephrit...

We show that any simply connected rectifiable domain Ω can be decomposed into Lipschitz crescents using only crosscuts of the domain and using total length bounded by a multiple of the length of ∂Ω. In particular, this gives a new proof of a theorem of Peter Jones that such a domain can be decomposed into Lipschitz disks. 1991 Mathematics Subject Classification.

Several flaked-stone crescents from the northern Great Basin were recently identified within James M. Collins artifact collection held in Archaeological Research Collections, Department of Anthropology, Southern Methodist University. These artifacts are morphologically and technologically consistent with other pre-Columbian reported region. The two obsidian exhibit compositions that Whitehorse/...
