PURPOSE The focus of this systematic review was to assess the published data concerning zirconia dental implant abutments from various aspects. MATERIALS AND METHODS To identify suitable literature, an electronic search was performed using PubMed. The keywords "zirconia," "zirconium," "ceramic," "dental abutments," "dental implants," "plaque," and(More)
The environmental DNA (eDNA) technique is expected to become a powerful, non-invasive tool for estimating the distribution and biomass of organisms. This technique was recently shown to be applicable to aquatic vertebrates by collecting extraorganismal DNA floating in the water or absorbed onto suspended particles. However, basic information on eDNA release(More)
OBJECTIVE The new concept of cancer stem cells has implications in terms of possible application for novel diagnostic and therapeutic procedures. Recently, the CD133 molecule was reported as a marker of cancer stem-like cells in colorectal cancer (CRC). In this study, we examined the prognostic value of free cancer cells in peritoneal washings from CRC(More)
Glaucoma is a neurodegenerative disease in which increasing intraocular pressure leads to the progressive loss of retinal ganglion cells (RGCs) and blindness. Here, we report a neuroprotective effect of pituitary adenylate cyclase-activating polypeptide (PACAP) against RGC loss induced by high intraocular pressure in the rat. Vehicle or PACAP (1 fM to 1,000(More)
The aim of the present investigation was to study the influence of grain size on the strength of yttria-stabilized zirconia upon exposure to an additional heat treatment, mimicking the veneering process. The green bodies of zirconia discs prepared by cold isostatic pressing were sintered at 1,425, 1,500, or 1,575°C to customize the grain size. The(More)
The present study analyzed the kinetics of low-temperature degradation (LTD) in zirconia, and evaluated the influence of LTD and cyclic loading on the fracture resistance of monolithic zirconia molar crowns. Bar-shaped zirconia specimens were divided into nine groups and autoclaved at 134°C for 0-200h to induce LTD. The surface fraction and penetration(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) exerts a neuroprotective action against ischemic damage. This action is mediated by the interleukin-6 (IL-6) pathway. However, as the expression patterns of PACAP receptors and IL-6 following ischemia are not understood, we evaluated them in the mouse hippocampus in response to ischemia induced by(More)
BACKGROUND Acid electrolyzed water (AEW), which is produced through the electrolysis of dilute sodium chloride (NaCl) or potassium chloride solution, is used as a disinfectant in various fields because of its potent antimicrobial activity. The hydroxyl radical, an oxygen radical species, is often suggested as a putative active ingredient for AEW(More)
Retinal excitotoxicity is one of the major causes of retinal ganglion cell (RGC) death in glaucoma. Pituitary adenylate cyclase-activating polypeptide (PACAP) is a pleiotropic peptide with potent neuroprotective activity; however, whether it exerts such an effect in the retina and the mechanism by which RGCs are protected is still not well understood. In(More)
The type I interferon (I-IFN) gene has recently been cloned and sequenced in the common carp species Cyprinus carpio L. Carp I-IFN cDNA is composed of 675 base pairs and is translated into a protein of 186 amino acid residues. The carp I-IFN encodes a predicted signal peptide of 23 amino acid residues and contains the I-IFN family signature(More)
