Nanocomposite tribological coatings were designed to respond to changing environmental conditions by self-adjustment of their surface properties to maintain good tribological performance in any environment. These smart coatings have been dubbed “ch

To counteract the natural brittleness of oxide ceramic films and achieve better toughness, nanocomposite films combining yttria-stabilized zirconia (YSZ) and gold were produced. A hybrid of magnetron sputtering and pulsed laser ablation was used to g

Composite coating architectures where hard nanocrystalline grains are embedded in an amorphous matrix provide considerable improvement in hardness, toughness, wear resistance, and environmental adaptation. Using this concept, nanocrystalline yttria s

Purified preparations of ovine large luteal cells were utilized in a series of experiments to test the effects of prostaglandins (PG) E2 and F2 alpha on cell morphology, viability and secretion of progesterone. Luteal cells were allowed to attach to

The role of cAMP in controlling steroidogenesis in small and large ovine luteal cells was examined. Corpora lutea collected from superovulated ewes (9-11 days postovulation) were dissociated, and the two cell types were purified by elutriation. Both

The corpus luteum is composed of two distinct steroidogenic cell types, both of which contribute significantly to the total progesterone secreted during the luteal phase of the oestrous cycle. The small luteal cells secrete very little progesterone u

Preparations of small and large steroidogenic cells from enzymatically dispersed ovine corpora lutea were utilized to study the in vitro effects of luteinizing hormone (LH) and prostaglandins (PG) E1, E2 and I2. Cells were allowed to attach to cultur

Experiments were conducted to determine the effect of additional gonadotropic support on induced corpora lutea of anestrous ewes. In one series of experiments, ewes were superovulated and half the ewes received an i.v. injection of 500 IU human chori
