Apathy is a common syndrome observed in many neurological conditions, including in up to 70% of patients with Parkinson's disease. Mechanisms underlying apathy are poorly understood and clinically we lack robust, objective detection methods. We aimed to address this using novel objective measures of motivation and reward sensitivity in relation to apathy in patients with Parkinson's disease. ⋯ Wellcome Trust.

The mechanisms that determine whether the heart adapts to overload stress, or fails, are poorly understood. NADPH oxidase (NOX) proteins produce reactive oxygen species (ROS) involved in redox signalling, and our recent studies have found that an increase in Nox4 during pressure overload protects the heart against failure. We aimed to identify novel Nox4-driven cardioprotective mechanisms that promote adaptive cardiac remodelling. ⋯ UK Medical Research Council, British Heart Foundation.

We have previously shown that patients with endometrial carcinoma express elevated concentrations of the endocannabinoid, anandamide (AEA), in both their plasma and their endometrial tissue and that the endometrial carcinoma cell line, Ishikawa, contains the receptors to which AEA binds. Several studies have reported that human and rodent cancer cell lines die in response to high AEA concentrations. The incidence of endometrial carcinoma continues to escalate and, although surgical treatment has improved, morbidity and mortality rates have not. A move towards a novel non-surgical therapeutic option is thus required, and the endocannabinoid system provides a good candidate target. We aimed to investigate the effects of AEA on the survival and proliferation of an endometrial carcinoma cell model. ⋯ University Hospitals of Leicester NHS Trust.

Rheumatoid arthritis is associated with a 50% increased risk in cardiovascular mortality. Inflammation is thought to accelerate atherosclerosis and might also lead to an inflammatory rupture-prone plaque phenotype. We tested the hypothesis that patients with active rheumatoid arthritis also have carotid plaque inflammation and that plaque inflammation correlates with clinical and serological markers of inflammation. ⋯ North West England MRC Clinical Pharmacology and Therapeutics Clinical Research Fellowship, National Institute for Health Research, AstraZeneca-University of Manchester Strategic Alliance Fund.

Metabolically unhealthy obesity is associated with adipose tissue inflammation and increased risk of type 2 diabetes. Dysfunctional adipose tissue remodelling has been implicated in development of metabolically unhealthy obesity, but the pathogenesis remains poorly characterised. We hypothesised that in health, tissue inhibitor of metalloproteinases 3 (TIMP3) modulates adipose tissue remodelling by regulating extracellular matrix turnover and shedding of the adipogenic regulator DLK1, but that in adipose tissue inflammation it might drive development of metabolically unhealthy obesity. ⋯ British Heart Foundation, Diabetes Research and Wellness Foundation Open Funding 2011.
