BACKGROUND Graphene oxide (GO) is a single layer carbon sheet with a thickness of less than 1 nm. GO has good dispersibility due to surface modifications with numerous functional groups. Reduced graphene oxide (RGO) is produced via the reduction of GO, and has lower dispersibility. We examined the bioactivity of GO and RGO films, and collagen scaffolds(More)
We describe two cases of acute eosinophilic pneumonia (AEP) presenting with high fever and hypoxia of acute onset with bilateral interstitial infiltrates on chest roentgenograms. Diagnosis was confirmed in each case by bronchoalveolar lavage and transbronchial lung biopsy in which the pathologic process was limited to the lung interstitium. High-resolution(More)
The morphological changes were examined in the present study in mouse cumulus-oocyte complexes and granulosa cells induced by the administration of pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG). Dissolution of the germinal vesicle (GVBD) occurred in oocytes at 3 hr after hCG administration. Partial expansion of the cumulus(More)
STUDY OBJECTIVES In this animal study we investigated whether CO2-induced intracranial hypertension was sustained in chronic hypercapnia. DESIGN We kept five rats in a 10% CO2-air mixture (PaCO2 73.4 +/- 6.2 Torr, mean +/- 1SD) for 22 weeks, and then measured the rats' intracranial pressure while breathing the 10% CO2- air mixture or the room air.
