Thriller

Shifts in genre definitions and classifications over time are very much a part of a living art form such as cinema. Films that today we might identify as bearing some of the hallmarks of the thriller, but which were not understood as such at the time of release, have been made in Australia since the earliest days of narrative cinema. The Story of the Kelly Gang (Charles Tait, 1906) contains some of the thriller’s stock elements: crime, conspiracy, suspense, a chase, heroes and villains. The fact that these elements are not exclusive to the thriller underscores the point that genres change, evolve, and often overlap. While contemporary reportage attests that The Story of the Kelly Gang thrilled audiences, it was not named as a ‘thriller’ at the time. Even so, a genealogy of the thriller can be traced through Australian film history, despite quiescent periods.

Infection control standards and credentialing

Infection control professionals (ICPs) play an integral part of developing, implementing, and evaluating infection control programs. In Australia, there is no minimum or standardized education to practice as an ICP. The Australasian College of Infection Prevention and Control, the professional body for ICPs in Australasia, sought to address the issue by developing a credentialing process.1, 2 and 3 This decision was made in recognition that self-regulation is one of the hallmarks of professionalism.4 The process of becoming credentialed as an ICP in Australia involves the submission of evidence against a range of criteria with a subsequent peer-review process...

YB-1, a key regulator of androgen receptor signalling

Reactivation of androgen receptor signalling is one of the hallmarks of prostate cancer progression to the terminal castrate resistant stage. A better understanding of mechanisms driving this adaptive response is essential for the development of innovative intervention strategies that effectively delay or halt prostate cancer progression. The Y-box binding protein 1 (YB-1) has been found to be closely associated with prostate cancer progression. By characterising its role in the adaptive process leading to castrate resistance, we aim to promote YB-1 as a novel therapeutic target in advanced prostate cancer.

Thymidine phosphorylase in cancer; Enemy or friend?

Thymidine phosphorylase (TP) is a nucleoside metabolism enzyme that plays an important role in the pyrimidine pathway.TP catalyzes the conversion of thymidine to thymine and 2-deoxy-α-D-ribose-1-phosphate (dRib-1-P). Although this reaction is reversible, the main metabolic function of TP is catabolic. TP is identical to the angiogenic factor platelet-derived endothelial-cell growth factor (PD-ECGF). TP is overexpressed in several human cancers in response to cellular stressful conditions like hypoxia, acidosis, chemotherapy and radiotherapy. TP has been shown to promote tumor angiogenesis, invasion, metastasis, evasion of the immune-response and resistance to apoptosis. Some of the biological effects of TP are dependent on its enzymatic activity, while others are mediated through cytokines like interleukin 10 (IL-10), basic fibroblast growth factor (bFGF) and tumour necrosis factor α (TNFα). Interestingly, TP also plays a role in cancer treatment through its role in the conversion of the oral fluoropyrimidine capecitabine into its active form 5-FU. TP is a predictive marker for fluoropyrimidine response. Given its various biological functions in cancer progression, TP is a promising target in cancer treatment. Further translational research is required in this area.
