Responsiveness Of Higher Education Programs To Policy And Recommendations In The Biopharmaceutical Sector, Maeve Scott

Other resources

This essay will review the business and government policies relevant to the biopharmaceutical sector which influence higher education programs. The mechanisms which enable higher education to adapt to policy will be summarised and the pace of the response estimated.

Higher education (HE) programs need to respond in a timely manner to dynamic industries to maximise opportunities for graduates and support the Irish economy. The author manages internships and teaches on pharmaceutical science programs and aims to ensure the program is current to maximise student success. This review intends to identify the most relevant policy sources that can inform the Pharmaceutical …

Piperlongumine (Piplartine) And Analogues: Antiproliferative Microtubule-Destabilising Agents, Mary J. Meegan, Seema M. Nathwani, Brendan Twamley, Daniela M. Zisterer, Niamh O'Boyle

Articles

Piperlongumine (piplartine, 1) is a small molecule alkaloid that is receiving intense interest due to its antiproliferative and anticancer activities. We investigated the effects of 1 on tubulin and microtubules. Using both an isolated tubulin assay, and a combination of sedimentation and Western blotting, we demonstrated that 1 is a tubulin-destabilising agent. This result was confirmed by immunofluorescence and confocal microscopy, which showed that microtubules in MCF-7 breast cancer cells were depolymerised when treated with 1. We synthesised a number of analogues of 1 to explore structure-activity relationships. Compound 13 had the best cytotoxic profile of this series, …

Isolation And Partial Characterization Of Bioactive Fucoxanthin From Himanthalia Elongata Brown Seaweed: A Tlc-Based Approach, Gaurav Rajauria, Nissreen Abu-Ghannam

Articles

Seaweeds are important sources of carotenoids, and numerous studies have shown the beneficial effects of these pigments on human health. In the present study, Himanthalia elongata brown seaweed was extracted with a mixture of low polarity solvents, and the crude extract was separated using analytical thin-layer chromatography (TLC).The separated compounds were tested for their potential antioxidant capacity and antimicrobial activity against Listeria monocytogenes bacteria using TLC bioautography approach. For bio-autography, the coloured band on TLC chromatogram was visualized after spraying with DPPH and triphenyltetrazolium chloride reagents which screen antioxidant and antimicrobial compounds, respectively, and only one active compound was screened …
