IL-1 alpha and IL-6 levels in the cornea are dramatically elevated in the regenerated epithelium during the early stages of alkali burn, and may play an important role in associated corneal damage and repair.
The charge‐discharge behavior of a lithium metal anode in propylene carbonate (PC) electrolyte containing added
CO2
was investigated using in situ ac impedance measurements during galvanostatic cycling. In PC electrolyte with
CO2
, the anode's cycle life was twice as long and its charge transfer resistance was smaller than in the same electrolyte without
CO2
. These enhancements are observed only when lithium is electrodeposited in the presence of
CO2
on nickel substrate; the enhancement does not occur when lithium is deposited without
CO2
and is cycled with
CO2
. Even large amounts of
H2O
in the electrolyte during cycling do not adversely affect the cycle life enhancement by
CO2
. The
CO2
enhancement seems to be due to products formed by reaction of lithium with
CO2
on the electrodeposited lithium surface.
Electrodeposited lithium produced with and without CO2 in LiC1O4/propylene carbonate electrolytes was investigated for charge-discharge cycleability, surface morphology, and composition of the surface layer. The addition of CO2 in the electrolyte enhances the cycleability, produces smoother surface morphology, and forms Li2CO3 in the inner region of the surface film. This paper describes experimental results showing those three different effects of CO2 addition, and discusses the interrelation among them.
In this study, we report a tumor that resembled previously reported uncommon tumors histologically similar to ameloblastoma or adenomatoid odontogenic tumor (AOT), showing the formation of hard tissue. We evaluated the histological characteristics by reviewing the literature. The patient was a 19-year old male. The lesion was located from the canine to third molar in the right mandible and was unicystic with a comparatively clear demarcation. The tumor tissue was cystic overall, showing multiple formation of small and large cysts. The tumor tissue resembled a variant form of plexiform ameloblastoma. Formation of dentin and dentinoid was observed in the tumor stroma, whereas formation of enamel was not observed. Very few cases of a variant form of ameloblastoma that shows formation of dentinoid have been reported, and the histological picture in this study closely resembled previously reported "adenoid ameloblastoma with dentinoid".
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
