The mobilization of triacylglycerides from storage in adipocytes to the liver is a vital response to the fasting state in mammalian metabolism. This is accompanied by a rapid translational activation of genes encoding mitochondrial, microsomal, and peroxisomal beta-oxidation in the liver, in part under the regulation of peroxisome proliferator-activated(More)
BACKGROUND Pelvic inflammatory disease (PID) is common and can lead to tubal factor infertility, ectopic pregnancy or chronic pelvic pain. Despite major UK government investment in the National Chlamydia Screening Programme, evidence of benefit remains controversial. The main aim of this trial was to investigate whether screening and treatment of chlamydial(More)
The study of biological systems in a holistic manner (systems biology) is increasingly being viewed as a necessity to provide qualitative and quantitative descriptions of the emergent properties of the complete system. Systems biology performs studies focussed on the complex interactions of system components; emphasising the whole system rather than the(More)
BACKGROUND Handheld computers and mobile devices provide instant access to vast amounts and types of useful information for health care professionals. Their reduced size and increased processing speed has led to rapid adoption in health care. Thus, it is important to identify whether handheld computers are actually effective in clinical practice.

OBJECTIVE To determine whether screening and treating women for chlamydial infection reduces the incidence of pelvic inflammatory disease over the subsequent 12 months. DESIGN Randomised controlled trial. SETTING Common rooms, lecture theatres, and student bars at universities and further education colleges in London. PARTICIPANTS 2529 sexually active(More)
AIMS Technological limitations have restricted in vivo assessment of intracellular pH (pH(i)) in the myocardium. The aim of this study was to evaluate the potential of hyperpolarized [1-(13)C]pyruvate, coupled with (13)C magnetic resonance spectroscopy (MRS), to measure pH(i) in the healthy and diseased heart. METHODS AND RESULTS Hyperpolarized(More)
BACKGROUND Many healthcare professionals use smartphones and tablets to inform patient care. Contemporary research suggests that handheld computers may support aspects of clinical diagnosis and management. This systematic review was designed to synthesise high quality evidence to answer the question; Does healthcare professionals' use of handheld computers(More)
Groups of food and water deprived rats were injected with either 2 mg/kg d-amphetamine, 9mg/kg dl-fenfluramine or isotonic saline immediately after the first presentation of a 25 percent solution of condensed milk for a 30 min period. When animals were tested for aversion to condensed milk 8 days later both drugs were found to cause a highly significant(More)
BACKGROUND Carnitine acetyltransferase catalyzes the reversible conversion of acetyl-coenzyme A (CoA) into acetylcarnitine. The aim of this study was to use the metabolic tracer hyperpolarized [2-(13)C]pyruvate with magnetic resonance spectroscopy to determine whether carnitine acetyltransferase facilitates carbohydrate oxidation in the heart. METHODS AND(More)
Hyperpolarized (13)C-labeled substrates directly provide a source of magnetic resonance (MR) signal to observe the substrates' real-time uptake and enzymatic conversion. The aim of this study was to optimize the concentration of hyperpolarized [1-(13)C]pyruvate infused as a metabolic tracer, by observing the mitochondrial conversion of pyruvate to(More)
