Sildenafil was the first selective inhibitor of phosphodiesterase-5 (PDE5) to be widely used for treating erectile dysfunction. Many recent studies have investigated the cardioprotective role of sildenafil in animal models. We evaluated the protective effects of sildenafil in experimental renal ischemia-reperfusion (IR) injury in two studies. In study 1,(More)
BACKGROUND AND AIMS Mesangial C3 deposition is frequently observed in patients with IgA nephropathy (IgAN). However, the role of complement in the pathogenesis or progression of IgAN is uncertain. In this observational cohort study, we aimed to identify the clinical implications of circulating C3 levels and mesangial C3 deposition and to investigate their(More)
Sildenafil is the first commercially available selective inhibitor of phosphodiesterase-5 (PDE5) and is widely used for the treatment of erectile dysfunction. In recent years, investigations of the role of sildenafil in cardioprotection in animal models have received considerable interest. We evaluated whether sildenafil can attenuate cisplatin-induced(More)
Granulocytic sarcoma (GS) is a rare manifestation of leukemia and has been reported in 3-5% of acute myelogenous leukemia (AML) patients. GS in the uterine cervix is very rare and is also called chloroma because of its greenish appearance. We present the case of a patient whose disease relapsed as chloroma of the uterine cervix after bone marrow(More)
PURPOSE Renin-angiotensin system activation is involved in inflammation and fibrosis in the kidney. Aliskiren, a direct renin inhibitor, decreases renin-angiotensin system activation, including plasma renin activity and angiotensin II, but increases the prorenin level, which may promote inflammation and fibrosis in renal tissue. Thus, we evaluated whether(More)
Focal segmental glomerulosclerosis (FSGS) is characterized by focal and segmental obliteration of glomerular capillary tufts with increased matrix. FSGS is classified as collapsing, tip, cellular, perihilar and not otherwise specified variants according to the location and character of the sclerotic lesion. Primary or idiopathic FSGS is considered to be(More)
The goal of this study was to compare the diagnostic use and safety of endorectal coil (ERC) MRI with those of phased-array coil MRI. We retrospectively included 91 consecutive patients who had undergone 1.5-T MRI with ERC or with phased-array coil MRI before radical prostatectomy at our institution. We compared 47 patients’ phased-array coil MRI and 44(More)
The pathogenic role of T cells in hypertension has been documented well in recent animal studies. However, the existence of T-cell-driven inflammation in human hypertension has not been confirmed. Therefore, we undertook immunologic characterization of T cells from patients with hypertension and measured circulating levels of C-X-C chemokine receptor type 3(More)
Neoplasms and tumorlike lesions that originate from chest wall tissues are uncommon compared with tumors in other parts of the body, and unfamiliarity with these disease entities can cause diagnostic difficulties for radiologists. Furthermore, the imaging features of many of these tumors are nonspecific, particularly those that are locally aggressive.(More)
