A whole cell-based Matrix-assisted laser desorption/ionization mass spectrometry lipidomic assay for the discovery of compounds that target lipid a modifications.

Introduction: Matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) is a powerful analytical technique that has been applied to a wide variety of applications ranging from proteomics to clinical diagnostics. One such application is its use as a tool for discovery assays, such as monitoring the inhibition of purified proteins. With the global threat from antimicrobial-resistant (AMR) bacteria, new and innovative solutions are required to identify new molecules that could revert bacterial resistance and/or target virulence factors.

Do responsive sleep interventions impact mental health in mother/infant dyads compared to extinction interventions? A pilot study.

Methods to improve sleep in infants commonly involve some ignoring (extinction) but are often unpopular with mothers worried about infant distress when left to cry. Alternative more responsive methods are needed. This pilot study evaluated stress, maternal depressive symptomology and sleep in mother/infant dyads, between Responsive, Controlled Crying and Control groups.

Evaluating Accessible Sleep Health Information in Rural and Urban Contexts: Delivery Face-to-Face or Online?

Objective: New parents need education about infant sleep but is not universally available especially not in regional and rural areas. We delivered sleep education both face-to-face and online to test sleep knowledge acquisition for parents wherever they reside. Best practice delivery of accessible sleep health information for new families needs to be investigated more carefully in order for specialist services to be universally available.

Discovery of potent and selective 5-azaindazole inhibitors of leucine-rich repeat kinase 2 (LRRK2) - Part 1.

Parkinson's disease is a relatively common neurological disorder with incidence increasing with age. Present treatments merely alleviate the symptoms and do not alter the course of the disease, thus identification of disease modifying therapies represents a significant unmet medical need. Mutations in the LRRK2 gene are risk-factors for developing PD and it has been hypothesized that the increased kinase activity of certain LRRK2 mutants are responsible for the damage of the dopaminergic neurons, thus LRRK2 inhibitors offer the potential to target an underlying cause of the disease.

The impact of sample type and procedural attributes on relative acceptability of different colorectal cancer screening regimens.

Objective: In Australia and other countries, participation in colorectal cancer (CRC) screening using fecal occult blood testing is low. Previous research suggests that fecal sampling induces disgust, so approaches not involving feces may increase participation. This study aimed to determine population preferences for CRC screening tests that utilize different sample collections (stool, blood, and saliva) and the extent to which specific attributes (convenience, performance, and cost) impact this preference.

Patterns of participation over four rounds of annual fecal immunochemical test-based screening for colorectal cancer: what predicts rescreening?

Background: Participation at the recommended intervals is critical for screening to be effective in reducing colorectal cancer (CRC) incidence. This study describes patterns of screening participation over four rounds of fecal immunochemical testing (FIT) to identify whether demographic variables and prior screening satisfaction are significantly associated with patterns of re-participation.

Methods: Baseline surveys were mailed to 4000 South Australians randomly selected from the electoral-roll.

Factors affecting faecal immunochemical test positive rates: demographic, pathological, behavioural and environmental variables.

Objectives: Positive rates in faecal immunochemical test (FIT)-based colorectal cancer screening programmes vary, suggesting that differences between programmes may affect test results. We examined whether demographic, pathological, behavioural, and environmental factors affected haemoglobin concentration and positive rates where samples are mailed.

Methods: A retrospective cohort study; 34,298 collection devices were sent, over five years, to screening invitees (median age 60.

Behavioural and demographic predictors of adherence to three consecutive faecal occult blood test screening opportunities: a population study.

Background: Social cognitive variables are often examined for their association with initial participation in colorectal cancer screening. Few studies have examined the association of these variables with adherence to multiple screening offers i.e.

Shift to earlier stage at diagnosis as a consequence of the National Bowel Cancer Screening Program.

Objective: To assess the impact of the National Bowel Cancer Screening Program (NBCSP) in South Australia.

Design, Setting And Participants: A cohort comparison of colorectal cancer (CRC) patient data from the NBCSP register and the South Australian Cancer Registry. Patient records of those invited to take part in screening through the NBCSP, those who participated in the program, and those with positive test results were compared with those of the rest of the study population (excluding the group of interest) on an intention-to-screen basis.

Synthesis and structure-activity relationships of a novel series of pyrimidines as potent inhibitors of TBK1/IKKε kinases.

The design, synthesis and structure-activity relationships of a novel series of 2,4-diamino-5-cyclopropyl pyrimidines is described. Starting from BX795, originally reported to be a potent inhibitor of PDK1, we have developed compounds with improved selectivity and drug-like properties. These compounds have been evaluated in a range of cellular and in vivo assays, enabling us to probe the putative role of the TBK1/IKKε pathway in inflammatory diseases.
