Carrot yellow leaf virus is associated with carrot internal necrosis.

Internal necrosis of carrot has been observed in UK carrots for at least 10 years, and has been anecdotally linked to virus infection. In the 2009 growing season some growers had up to 10% of yield with these symptoms. Traditional diagnostic methods are targeted towards specific pathogens.

Role of multidetector computed tomography in the diagnosis and management of patients attending the rapid access chest pain clinic, The Scottish computed tomography of the heart (SCOT-HEART) trial: study protocol for randomized controlled trial.

Background: Rapid access chest pain clinics have facilitated the early diagnosis and treatment of patients with coronary heart disease and angina. Despite this important service provision, coronary heart disease continues to be under-diagnosed and many patients are left untreated and at risk. Recent advances in imaging technology have now led to the widespread use of noninvasive computed tomography, which can be used to measure coronary artery calcium scores and perform coronary angiography in one examination.

Infusion of Mg in humans acutely reduces serum insulin levels: a pilot study.

Background: Infusion of Mg for therapeutic purposes is still a matter for debate. Dosages vary considerably, yet subclinical effects on normal physiology are largely ignored. In human and animal models, interactions between Mg and insulin exist, thus we have investigated the effect of infusing Mg on serum insulin, ionised Mg (Mg(2+)) and Ca (Ca(2+)) and plasma glucose in human volunteers.

Combustion-derived nanoparticulate induces the adverse vascular effects of diesel exhaust inhalation.

Aim: Exposure to road traffic and air pollution may be a trigger of acute myocardial infarction, but the individual pollutants responsible for this effect have not been established. We assess the role of combustion-derived-nanoparticles in mediating the adverse cardiovascular effects of air pollution.

Methods And Results: To determine the in vivo effects of inhalation of diesel exhaust components, 16 healthy volunteers were exposed to (i) dilute diesel exhaust, (ii) pure carbon nanoparticulate, (iii) filtered diesel exhaust, or (iv) filtered air, in a randomized double blind cross-over study.

The role of ACE inhibitor therapy in treating cardiovascular disease.

The first angiotensin-converting enzyme (ACE) inhibitors were introduced in 1981. They are used in the management of a variety of cardiovascular disorders and their role in hypertension, heart failure, managing asymptomatic and symptomatic left-ventricular dysfunction, post-myocardial infarction, stroke prevention, and diabetes is now well established. This is recognised in the National Service Framework for Coronary Heart Disease (Department of Health, 2000) and the guidelines from the British Hypertension Society (Ramsay et al, 1999).
