The primary purpose of this consensus statement is to provide an integrated perspective on current knowledge and expert opinion pertaining to sedentary behaviour in older adults on the topics of measurement, a...
Subepicardial delayed gadolinium enhancement in asymptomatic athletes: let sleeping dogs lie?
BR J SPORTS MED - 01 Jan 2016
BACKGROUND:
Subepicardial delayed gadolinium enhancement (DGE) patches without underlying cardiomyopathy is poorly understood. It is often reported as the result of prior silent myocarditis. Its prognostic relevance in asymptomatic athletes is unknown; therefore, medical clearance for competitive sports participation is debated. This case series aims to relate this pattern of DGE in athletes...

METHOD:
The 4-week Stand Up Comcare study (June-September 2011) aimed to reduce workplace sitting time via regularly interrupting and replacing sitting time throughout the day. Activity monitor (activPAL3) workplace data from contr...
Sedentary behaviour and health: mapping environmental and social contexts to underpin chronic disease prevention
BR J SPORTS MED - 01 Feb 2014
The time that children and adults spend sedentary-put simply, doing too much sitting as distinct from doing too little physical activity-has recently been proposed as a population-wide, ubiquitous influence on health outcomes. It has been argued that sedentary time is likely to be additional to the risks associated with insufficient moderate-to-vigorous physical activity. New evidence identifie...
Associations of overall sitting time and TV viewing time with fibrinogen and C reactive protein: the AusDiab study
BR J SPORTS MED - 01 Feb 2015
BACKGROUND/AIM:
Sedentary behaviour is associated with increased risk for all-cause and cardiovascular mortality. Plasma fibrinogen and C reactive protein (CRP)-key inflammatory and/or haemostatic markers-may contribute to this association; however, few studies have examined their relationships with sedentary behaviours. We examined associations of overall sitting and TV viewing time with fibr...

The longitudinal relationship between changes in body weight and changes in medial tibial cartilage, and pain among community-based adults with and without meniscal tears
ANN RHEUM DIS - 01 Sep 2014
INTRODUCTION:
Meniscal tears are commonly found on MRI and increase the risk for radiographic knee osteoarthritis (OA). While meniscectomy is recommended when knee pain is severe or functionally disabling, it is unclear how to best treat meniscal tears without these symptoms. The aim of this longitudinal study was to examine the effect of weight change on knee cartilage and pain in a cohort of...
Smad7 gene delivery prevents muscle wasting associated with cancer cachexia in mice
SCI TRANSL MED - 20 Jul 2016
Patients with advanced cancer often succumb to complications arising from striated muscle wasting associated with cachexia. Excessive activation of the type IIB activin receptor (ActRIIB) is considered an important mechanism underlying this wasting, where circulating procachectic factors bind ActRIIB and ultimately lead to the phosphorylation of SMAD2/3. Therapeutics that antagonize the binding...
Stimulation of liver X receptor has potent anti-HIV effects in a humanized mouse model
J PHARMACOL EXP THER - 01 Sep 2015
Previous studies demonstrated that liver X receptor (LXR) agonists inhibit human immunodeficiency virus (HIV) replication by upregulating cholesterol transporter ATP-binding cassette A1 (ABCA1), suppressing HIV production, and reducing infectivity of produced virions. In this study, we extended these observations by analyzing the effect of the LXR agonist T0901317 [N-[4-(1,1,1,3,3,3-hexafluoro-...
Inhibition of extracellular cyclophilins with cyclosporine analog and development of atherosclerosis in apolipoprotein E-deficient mice
J PHARMACOL EXP THER - 01 Jun 2015
Cyclophilins exert both intracellular and extracellular activities related to immune responses and inflammation, which have been implicated in pathogenesis of atherosclerosis. Pan-inhibition of cyclophilins has both pro- and antiatherosclerotic properties, but specific contributions of extracellular and intracellular cyclophilins to these effects have not been characterized. Here, using selecti...
Anti-inflammatory functions of apolipoprotein a-I and high-density lipoprotein are preserved in trimeric apolipoprotein a-I
J PHARMACOL EXP THER - 01 Jan 2013
Raising high-density lipoprotein (HDL) levels is proposed as an attractive target to treat cardiovascular disease. However, a number of clinical studies examining the effect of HDL-raising therapies have been prematurely halted due to futility. Therefore there is a need for alternative therapies. Infusion of reconstituted HDL (rHDL) particles is still considered as a viable approach to increasi...
