Abstract
The ethyl acetate and dichloromethane-soluble fractions, from a soft coral Sarcophyton trocheliophorum total methanolic extract, exhibited significant anti-leishmanial and cytotoxic activities. These active fractions yielded a new cembranoid diterpene (1), two known analogues [sarcotrocheliol (2) and sarcophine (3)], and two sterols [(24S)-24-methylcholesterol (4) and gorgosterol (5)]. The structure of the new diterpene (1) was determined via a detailed analysis of its spectroscopic data. Compounds 3 and 5 demonstrated noticeable cytotoxicity on A549 (IC50 17.4 ± 1.9 µg/ml) and HepG2 (IC50 17.7 ± 1.5 µg/ml) cell lines, respectively. None of the isolates 1‒5 showed detectable anti-leishmanial activity (IC50 >100 µg/ml).

Abstract
The objective of this research was to evaluate the cytotoxic activities of the fractions and isolated compounds of the soft corals Litophyton arboreum against A549, MCF-7 and HepG2 cell lines by MTT assay method, and to chemically investigate the various metabolites of its total extract using LC-HR-ESI-MS metabolomic profiling. The metabolomic profiling revealed the presence of various metabolites, mainly sesquiterpenes and steroids reported for the first time in L. arboreum. Additionally, eight compounds (1-8) have been isolated from the n-hexane-chloroform (1:1) fraction that exhibited noticeable activity towards A549, MCF-7 and HepG2 cell lines. The steroids (5 and 6), and the sesquiterpene (1) exerted noticeable activity against A549 cell line (IC50 28.5 ± 4.4, 36.9 ± 2.9 and 67.3 ± 9.9 µM/mL, respectively) compared to etoposide as standard cytotoxic agent (IC50 48.3 ± 7.6 µM/mL). Compound 6 also exhibited cytotoxicity against MCF-7 cell line (IC50 55.3 ± 4.9 µM/mL).

Abstract
Using homology searches, we identified a novel human inhibitor of apoptosis (IAP) gene. This gene has two splicing variants that contain open reading frames of 298 and 280 amino acids and both contained a single copy of baculovirus IAP repeat (BIR) and RING domain. We refer here to the longer and shorter variants as Livin alpha and beta, respectively. Semiquantitative reverse transcriptase-polymerase chain reaction demonstrated a tissue-specific and non-correlated expression pattern in both adult and fetal tissues. Both mRNA variants were detected in various transformed cell lines. Despite their very close similarity, the two isoforms have different antiapoptotic properties. Both isoforms have a significant antiapoptotic activity in the Jurkat T cell line after triggering apoptosis via tumor necrosis factor and CD95 receptors. The Livin alpha but not beta protects cells from apoptosis induced by staurosporine, but in contrast, apoptosis initiated by etoposide was blocked only by the beta isoform. This difference in biological activities may indicate the presence of critical amino acids outside the BIR and RING domains. These functional and tissue distribution differences of Livin alpha and beta suggest that Livin may play a complex role in the regulation of apoptosis.

Abstract
Several years ago, a field strain retrovirus, avian hemangioma virus (AHV), was isolated from hemangioma tumors in layer hens. Sequence analysis indicated that the AHV genome contains the three prototypic retroviral genes, gag, pol, and env, and is devoid of an oncogene. In cultured endothelial cells, however, AHV induced a significant cytopathic effect through a typical apoptotic cascade. We now demonstrate that AHV also induces cell proliferation and anchorage-independent growth of BSC-1 epithelial cells and NIH-3T3 fibroblasts. This was shown by measurements of (1) cell viability, (2) DNA synthesis, (3) flow cytometry analysis of the cell DNA content, and (4) clonogenic efficiency of the infected cells. Anchorage-independent cell growth was demonstrated by colony formation in soft agar. Moreover, the AHV env gene was cloned into a MuLV-based retroviral vector, and infection of NIH-3T3 cells with this vector induced cell proliferation as well as clonogenic growth. These results suggest that AHV, which is devoid of an oncogene, is a pleiotropic activator capable of inducing either apoptosis or cellular proliferation, depending on the infected cell type.

Abstract
An investigation has been carried out on the effect of gamma-radiation on the absorption spectra of aqueous solutions of the hydroxyanthraquinone dyes, alizarin and alizarin red S. Ionizing radiation at absorbed doses over the range 10(5)-3 x 10(6) rad brought about gradual bleaching of aerated (oxygenated) dye solutions. The radiolytic bleaching was enhanced through addition of hydrogen peroxide, as expected. A mechanism for the radiolytic reaction is proposed, based on chemical attack of the chromophore by radicals and radical ions as aqueous radiolysis products. Suggestions are made for possible radiation dosimetry by means of spectrophotometric analysis of the absorption spectra.
