Journal ArticleDOI

TL;DR: Although the Japanese coefficient improves the accuracy of G FR estimation of the original MDRD study equation, a new equation is needed for more accurate estimation of GFR in Japanese patients with CKD stages 3 and 4.

TL;DR: A genome-wide association study of IgA nephropathy (IgAN), the most common form of glomerulonephritis, with discovery and follow-up in 20,612 individuals of European and East Asian ancestry is performed, suggesting a possible role for host–intestinal pathogen interactions in shaping the genetic landscape of IgAN.
Journal ArticleDOI
Clinical responses to EGFR-tyrosine kinase inhibitor retreatment in non-small cell lung cancer patients who benefited from prior effective gefitinib therapy: a retrospective analysis.

TL;DR: The results indicate that a 2nd EGFR-TKI treatment can be an effective treatment option for gefitinib responders and are generally acceptable and comparable to those observed for the initial gefithinib therapy.
Journal ArticleDOI
Clinicopathological characteristics of patients with IgG4-related tubulointerstitial nephritis

TL;DR: It is suggested that renal parenchymal lesions actually develop in association with IgG4-related disease, for which the term 'IgG 4-related tubulointerstitial nephritis' is proposed.
Journal ArticleDOI
Expression, roles, receptors, and regulation of osteopontin in the kidney.
TL;DR: Studies utilizing OPN gene-deficient mice, antisense-treated or anti-OPN-treated animals have demonstrated that OPN promotes accumulation of macrophages, and may play a role in macrophage-mediated renal injury, but that the effect may be mild and short-lived.
