Abstract
Geijera Schott is a plant genus of the Rutaceae Juss. (rue and citrus) family, comprising six species which are all native to Oceania. Of the plants belonging to this genus, the most significant species that has a customary use is Geijera parviflora, which was used by Indigenous Australians, primarily as a pain reliever. Herein, a comprehensive review of the literature published on the genus Geijera from 1930 to 2023 was conducted. This is the first review for this plant genus, and it highlights the chemical constituents reported to date, together with the range of pharmacological properties described from the various species and different parts of the plant. These properties include anti-inflammatory, anti-microbial, anti-parasitic, insect repellent, analgesic, neuroactive, and anti-cancer activities. Finally, a reflection on some of the important areas for future focused studies of this plant genus is provided.

Abstract
Many targeted natural product isolation approaches rely on the use of pre-existing bioactivity information to inform the strategy used for the isolation of new bioactive compounds. Bioactivity information can be available either in the form of prior assay data or via Structure Activity Relationship (SAR) information which can indicate a potential chemotype that exhibits a desired bioactivity. The work described herein utilizes a unique method of targeted isolation using structure-based virtual screening to identify potential antibacterial compounds active against MRSA within the marine sponge order Verongiida. This is coupled with molecular networking-guided, targeted isolation to provide a novel drug discovery procedure. A total of 12 previously reported bromotyrosine-derived alkaloids were isolated from the marine sponge species Pseudoceratina durissima, and the compound, (+)-aeroplysinin-1 (1) displayed activity against the MRSA pathogen (MIC: <32 µg/mL). The compounds (1−3, 6 and 9) were assessed for their central nervous system (CNS) interaction and behavioral toxicity to zebrafish (Danio rerio) larvae, whereby several of the compounds were shown to induce significant hyperactivity. Anthelmintic activity against the parasitic nematode Haemonchus contorutus was also evaluated (2−4, 6−8).

Abstract
This study provides a review of all isolated natural products (NPs) reported for sponges within the order Verongiida (1960 to May 2020) and includes a comprehensive compilation of their geographic and physico-chemical parameters. Physico-chemical parameters were used in this study to infer pharmacokinetic properties as well as the potential pharmaceutical potential of NPs from this order of marine sponge. In addition, a network analysis for the NPs produced by the Verongiida sponges was applied to systematically explore the chemical space relationships between taxonomy, secondary metabolite and drug score variables, allowing for the identification of differences and correlations within a dataset. The use of scaffold networks as well as bipartite relationship networks provided a platform to explore chemical diversity as well as the use of chemical similarity networks to link pharmacokinetic properties with structural similarity. This study paves the way for future applications of network analysis procedures in the field of natural products for any order or family.

Abstract
RMIT University was the first to offer a comprehensive Masters of Toxicology in Australasia 19 years ago. In 2001 the program was transformed into two stages, leading to a Graduate Diploma and Master of Applied Science in Toxicology. Now, these programs are fully online and suitable for graduates living and working anywhere in the world. The modular distance-learning courses are specifically designed to equip students with essential skills for entering fields such as chemical and drug evaluation; risk assessment of chemicals in the workplace; environmental and food toxicology. RMIT's online course delivery system has made it possible to deliver the toxicology programs, both nationally and internationally. The learning material and interactive activities (tests and quizzes, discussion boards, chat sessions) use Blackboard and WebBoard, each with a different educational function. Students log in to a Learning Hub to access their courses. The Learning Hub enables students to extend their learning beyond the classroom to the home, workplace, library and any other location with Internet access. The teaching staff log in to the Learning Hub to maintain and administer the online programs and courses which they have developed and/or which they teach. The Learning Hub is also a communication tool for students and staff, providing access to email, a diary and announcements. The early experience of delivering a full toxicology program online is very positive. However this mode of teaching continues to present many interesting technical, educational and cultural challenges, including: the design and presentation of the material; copyright issues; internationalization of content; interactive participation; and the assessment procedures.

Abstract
BACKGROUND Hyperacute rejection in xenotransplantation is caused by activation of complement (C) on endothelium. We have previously shown that purified C-regulators of the pig (CD59 and membrane cofactor protein [MCP]) are efficient regulators of human C (HuC). The aim of this study was to clarify the role of endogenously expressed C-regulatory molecules on pig endothelium in the protection against hyperacute rejection. METHODS Porcine aortic endothelial cells (PAEC) were harvested and cultured for various passages. PAEC were examined for the expression of endogenous pig CD59 and MCP by flow cytometry. PAEC were assessed for their susceptibility to lysis by HuC. The effect of phorbol 12-myristate 13-acetate and various cytokines on the expression of MCP and CD59 and C-susceptibility was assessed. RESULTS Primary PAEC showed an initial high level of expression of pig CD59, however, upon culturing, CD59 levels decreased dramatically to about 20% after five passages. In contrast, levels of MCP doubled upon culturing of PAEC to confluency and remained stable during at least five passages. Primary cells and cells in the early passages were more resistant to HuC than cells that were cultured for longer. Blocking the function of CD59 but not of MCP using monoclonal antibody increased the susceptibility to HuC. Purified human CD59 incorporated to a level of expression similar to that of pig CD59 reversed the increased C-susceptibility, suggesting that pig and human CD59 are similarly protective against HuC. Increase of C-resistance and of expression of pig MCP, but not of CD59, was achieved upon incubation with phorbol 12-myristate 13-acetate. Tumor necrosis factor-alpha, interleukin-1beta, interleukin-4, or interferon-gamma had no effect on C-regulator expression or C-susceptibility. CONCLUSIONS These data demonstrate the importance of using primary PAEC or cells in the first passages of culturing in in vitro models of xenotransplantation and show that pig MCP and, in particular, pig CD59 play an important role in protection of PAEC from HuC.

Abstract
OBJECTIVES Four phospholipase C (PLC) beta isoforms have been described in pig aortic vascular smooth muscle. The aim was to determine if all four PLC beta isoforms are commonly expressed in vascular smooth muscle cells (VSMC) of three species, i.e. pig, human and rat, and if the individual isoforms had distinctive intracellular distributions. METHODS Vascular smooth muscle cell cultures were derived from explants of porcine and rat aorta and a human renal artery cell line. PLC beta isoform content was resolved using Western blotting. Intracellular location was determined by immunocytochemistry and confocal microscopy. RESULTS All three species expressed PLCs, beta 1, beta 2, beta 3 and beta 4. In all species, PLC beta 1 demonstrated foci of concentration throughout the cytoplasm; PLC beta 2 demonstrated a punctate pattern that was principally at the cell periphery or was in the Golgi, depending upon the antibody used; PLC beta 3 was also cytoplasmic but showed a different pattern from PLC beta 1 and PLC beta 4 was cytoplasmic, except in pig quiescent cells, where it was associated with filamentous structures at the intersection with the plasma membrane. CONCLUSIONS VSMCs of three different species express all four PLC beta isoforms. Each isoform has a unique and consistent signature of distribution that is generally common to all species.
