Dietary vitamin E, highly expressed in palm oil, exists as either tocopherols or tocotrienols. Evidence indicates that vitamin Es maybe potent cancer preventive agents. In this study, the y- and O- isoforms of vitamin E were found to he the most effective at cancer cell growth inhibition, with the tocotrienols being more effective than the tocopherols in androgen-independent PC-3 prostate cancer cells. To assure that these compounds were selective toward cancer cells, the growth arrest of PrEC normal prostate cells was compared to PC-3 cells. At concentrations of -30 iM dietary, y-vitamin Es showed no signficant growth arrest on PrEC cell growth, hut selectively inhibited growth in the PC-3 cancer cells. Moreover y-Tocotrienol demonstrated a greater potential to inhibit growth in cancer cells at these lower concentrations than did y-Tocopherol. Two independent pathways important in carcinogenesis were tested: PPAR y and NFicB. The PPAR y was up regulated by both dietary y-vitamin Es by the modulation of the endogenous ligand 15-S-HETE, while NFicB was only regulated by y-Tocotrienol. The modulation of NFicB was confirmed by the down regulation of the pro-Apoptotic proteins clAP, xIAP, and BcL-2 which potentiate apoptosis and are down stream effectors of NFicB.

In June 2012, the Supreme Court of the United States decided the fate of the Patient Protection and Affordable Care Act in a case called National Federation of Independent Business v. Sebelius. While initially the decision seemed favorable to supporters of the bill, Chief Justice Roberts’ majority opinion could likely render the bill ineffective in implementation and it creates more Constitutionally confusing precedent than it resolves. Among the questions that now rise to the surface are: will Congress be able to raise the tax to a level where it will become effective? What is now mandatory for states to adopt into their Medicaid programs? Where is the line for the federal government with regards to coercion? What are the definitions of direct and indirect taxes? And, how binding is the Origination Clause of the Constitution?

Thesis deals with relationship between histomorphological and molecular-genetic findings of selected salivary gland tumors. Author, as a molecular-cytogeneticist mainly focused on detection of tumor-specific translocations of the salivary gland tumors which can serve as differential diagnostic markers. The thesis is composed as a commented files of authors own publications, and it is divided into four parts. First part deepens the knowledge of salivary adenoid cystic carcinoma. It was proved, that t(6;9)(q22-23;p23-24) resulting in fusion of transcription factors MYB-NFIB, or more rarely t(8;9) resulting in MYBL1-NFIB fusion represent robust differential diagnostic marker of adenoid cystic carcinoma. Further it was proved, that the 1p36 deletion can serve as an unfavorable prognostic indicator of adenoid cystic carcinoma, as the patients with 1p36 deletion had significantly lower survival. Second part summarizes new developments about mammary analogue secretory carcinoma (MASC), which was described by our group as a new salivary tumor entity characterized by translocation t(12;15)(p13;q25) resulting in ETV6-NTRK3 fusion. Another novel observation is a discovery of ETV6-RET fusion in a subset of MASC cases. Further, the first two MASCs of nasal mucosa origin have been described. Third part consists...
