A platelet transfusion was avoided in 104 of 145 patients who received eltrombopag (72%) and in 28 of 147 who received placebo (19%) (P<0.001).
No significant difference between the eltrombopag and placebo groups Go6983 was observed in bleeding episodes of WHO grade 2 or higher, which were reported in 17% and 23% of patients, respectively. Thrombotic events of the portal venous system were observed in 6 patients who received eltrombopag, as compared with 1 who received placebo, resulting in the early termination of the study. The incidence and severity of other adverse events were similar in the eltrombopag and placebo groups.
Eltrombopag reduced the need for platelet transfusions in patients with chronic liver disease who were undergoing elective invasive procedures, but it was associated with an increased incidence of portal-vein thrombosis, as compared
with placebo. (Funded by GlaxoSmithKline; ELEVATE ClinicalTrials.gov number, NCT00678587.)”
“Current influenza virus vaccines provide protection in part by antibodies induced to the two surface glycoproteins, the hemagglutinin and the neuraminidase. As a result of the continuous antigenic drift of these glycoproteins, a frequent update of the composition of influenza vaccines is required. The search for more conserved viral epitopes ABT-737 cell line which would induce protective immunity against seasonal influenza viruses and eventually also to novel pandemic influenza viruses has a long history. The ectodomain of the Influenza A Virus M2 Protein has been identified as a possible candidate immunization against influenza. The present study describes the expression of cloned M2 gene in MDCK, HeLa, and COS-7 cells, i.e., in three established eukaryotic cell lines. The expression efficiency was demonstrated by immunofluorescent staining of transfected cells by ELISA, by SDS-PAGE-, and by Western blot-analysis. High level of expression was observed in COS-7 cells. Expression in Hela and PAK6 MDCK cells was less efficient. The plasmids constructed in this study may, after modifications,
be used for the production of a DNA vaccine. Alternatively the expression product could be refined and used as a purified antigen for the vaccine. Thus, the M2 recombinant protein provides an ideal product for further antigenic, biochemical, structural and functional characterization of the protein and for evaluating its potential for immunodiagnosis and in vaccine studies.

“Lysergic acid diethylamide (LSD) differs from other types of hallucinogens in that it possesses direct dopaminergic effects. The exact nature of this component has not been elucidated.
The present study sought to characterize the effects of several dopamine D-4 agonists and antagonists on the discriminative stimulus effect of LSD at two pretreatment times and 2,5-dimethoxy-4-iodoamphetamine (DOI), a selective 5-HT2A/2C agonist.
