A fiber-reinforced ceramic matrix composite material exhibiting increased matrix cracking strength and fracture toughness is produced by sequentially depositing a plurality of 5-500 nanometer-thick layers of a primary ceramic matrix material phase periodically separated by 1-100 nanometer-thick intermediate layers of a secondary matrix material phase onto the reinforcing fibers upon their consolidation. The resultant nanolayered matrix enhances the resistance to the onset of matrix cracking, thus increasing the useful design strength of the ceramic matrix composite material. The nanolayered microstructure of the matrix constituent also provides a unique resistance to matrix crack propagation. Through extensive inter-layer matrix fracture, debonding and slip, internal matrix microcracks are effectively diverted and / or blunted prior to their approach towards the reinforcing fiber, thus increasing the apparent toughness of the matrix constituent. This unique toughening mechanism serves to dampen energetic co-planar macrocrack propagation typically observed in conventionally manufactured ceramic matrix composites wherein matrix cracks are usually deflected at the fiber / matrix interphase region.

Leptin was previously demonstrated to exert potent immune modulatory properties in several immune mediated disorders. The aim of the study was to determine leptin's anti-tumor effect in a murine model of human hepatocellular carcinoma (HCC). In vivo, Athymic T cell deficient (nude) mice transplanted with 1×106 human Hep3B cells, followed by administration of two daily intraperitoneal doses of 0.5 mg / gram leptin for 6 weeks. Leptin administration induced a significant reduction in tumor size and improved survival in nude mice. Histologically, tumors of leptin-administered mice featured increased inflammatory exudate in interphase areas. Leptin-induced tumor suppression was associated with a significant increase in peripheral natural killer (NK) cell number. Splenocytes from leptin-treated mice featured decreased expression of CIS mRNA. To determine which lymphocyte subset is a prerequisite for the anti tumor effect of leptin, T&B cell deficient (Scid) mice and T,B& NK deficient (Scid-Beige) mice were subcutaneously implanted with Hep3B tumor cells, with and without the daily intraperitoneal administration of 0.5 mg / gram leptin for 6 weeks. SCID mice featured leptin-associated tumor suppression similar to those of nude mice. In contrast, NK-deficient SCID-Beige mice developed larger tumors. To further establish natural killer cell's central role in mediation of leptin's anti-tumor effect, NK cells were incubated in vitro with increasing doses of leptin, demonstrating a dose-dependent increase in cytotoxic activity. Incubation of leptin with hepatoma cell line was found to induce a dose-dependent reduction in hepatoma cell proliferation, suggesting an additive direct anti-tumor effect. Further synergism in inhibition of hepatoma cell proliferation in vitro was achieved following addition of natural killer cells. HCC cells expressed leptin receptor mRNA, while addition of leptin induced increased mRMA expression of STAT2 and SOCS1 on tumor cell lines. Leptin administration induces a significant suppression of human HCC. This effect is mediated by induction of natural killer cell proliferation and activation, and by direct inhibition of tumor growth. Decreased natural killer cell expression of inhibitory CIS protein and over expression of the anti-proliferative STAT2 and SOCS1 proteins in HCC lines may underline both anti cancerous effects of leptin.
