78. RBEMKM at 10% survival of HSG tumor cells was 0.84, which was nearly independent of the depth and beam energy.Primary carcinosarcoma of the liver is extremely rare. Here, we report an unusual case of carcinosarcoma of the liver containing combined hepatocellular carcinoma and cholangiocarcinoma. A 66-year-old man with a history of viral hepatitis B was admitted for investigation of multiple liver masses. Dynamic computed tomography revealed a mostly hypoenhancing main tumor with a peripheral ring enhancement and several satellite nodules. After transcatheter arterial chemoembolization and portal vein embolization, an extended right posterior sectionectomy was performed. The resected tumor was macroscopically a simple nodular type, 4.3 × 4.2 cm in diameter, with a dense fibrous capsule. The pathological findings showed that both carcinomatous and sarcomatous elements were present, and diagnosis of carcinosarcoma of the liver was confirmed. The carcinomatous element consisted of hepatocellular carcinoma and cholangiocarcinoma. The sarcomatous element was composed of spindle cells. Immunohistochemical studies demonstrated that cytokeratin AE1/AE3, human serum albumin, cytokeratin 7, and Arginase-1 were partially positive in tumor cells of the carcinomatous element but not in tumor cells of the sarcomatous element. Follow-up for 30 months after surgery has shown no signs of recurrence. Protein kinase C (PKC) is a promising drug target for various therapeutic areas. Natural products derived from plants, animals, microorganisms, and marine organisms have been used by humans as medicine from prehistoric times. Recently, several compounds derived from plants have been found to modulate PKC activities through competitive binding with ATP binding site, and other allosteric regions of PKC. As a result fresh race has been started in academia and pharmaceutical companies to develop an effective naturally derived small-molecule inhibitor to target PKC activities. Herein, in this review, we have discussed several natural products and their derivatives, which are reported to have an impact on PKC signaling cascade. All information presented in this review article regarding the regulation of PKC by natural products has been acquired by a systematic search of various electronic databases, including ScienceDirect, Scopus, Google Scholar, Web of science, ResearchGate, and PubMed. The keywords PKC, natuxtensive research is needed to circumvent the challenge of isoform specific regulation of PKC by natural products. Access and funding for newly approved treatments for non-small cell lung cancer (NSCLC) are often dependent on Health Technology Assessment (HTA) involving cost-effectiveness analysis. Whilst methods used by HTA agencies share many similarities, final decisions may differ. This may be the result, not justof price considerations, but also of variation in value judgements by different agencies. The aim of this study was to review international HTA evaluations to identify determinants of value and access for NSCLC treatments. A targeted review and analysis was undertaken of published HTAs for NSCLC across HTA agencies in six countries (Australia, Canada, England, France, Ireland and Scotland). Analysis of extracted data consisted of three stages descriptive analysis, bivariate analysis and multivariable analysis. The analysis included 163 HTAs that assessed oncological treatments for NSCLC from 2003 to 2019. The majority of HTA decisions (67.5%) were positive. However, some evidence of heterogeneity in HTA decisions and the factors informing them were identified. The most influential factors included in the multivariate model related to the HTA agency conducting the appraisal, the year of market authorisation, treatment type and the line of treatment. Heterogenous decision-making frameworks can present a challenge to developing HTA submissions. This research contributes to u
