Effect of cerium oxide on iron metabolism in mice.

The use of metal nanoparticles such as cerium oxide nanoparticles (nanoceria) in living organisms is attracting increasing attention. We administered nanoceria to chronic kidney disease model rats, including a 5/6 nephrectomy model and adenine administration model rats, and reported high phosphorus adsorption capacity and renal function improvement effects of nanoceria. However, the iron ion concentration in the serum fluctuated significantly after administration.

A Biochemical Corrosion Monitoring Sensor with a Silver/Carbon Comb Structure for the Detection of Living .

For the detection and monitoring of live bacteria, we propose a biochemical corrosion monitoring (BCM) sensor that measures galvanic current by using a Ag/C sensor comprising silver and carbon comb electrodes. The deposition of an suspension containing an LB liquid medium on the Ag/C sensor increased the galvanic current. The time required for the current to reach 20 nA is defined as .

Effects of cerium oxide nanoparticles on adenine-induced chronic kidney disease model rats.

Aim: Cerium oxide, particularly in nanoparticle form (nanoceria), has been investigated for biomedical applications as a promising new agent for treating several pathologies. The aim of the present study was to characterize the pharmacologic effects of nanoceria in an animal model of chronic kidney disease.

Methods: We created the chronic kidney disease animal model by feeding rats a 0.

Dismantling of Reinforced Concrete Using Steam Pressure Cracking System: Drilling and Crack Propagation.

This study investigated a new dismantling system for concrete structures using a steam pressure cracking agent. We improved the mechanical systems such that it can drill through reinforcing steel bars. Therefore, the control method of the system and shape of the drill tip were improved.

Cutting of Diamond Substrate Using Fixed Diamond Grain Saw Wire.

This study demonstrates that a single-crystal diamond substrate can be cut along designed lines using the diamond-saw-wire cutting method. We developed an original saw-wire fixed diamond-grain using a bronze solder with a high melting temperature. We created a unique product machine system with a high vacuum furnace and a bronze solder that contains a metallic compound.
