Replacement of Lost Substance P Reduces Fibrosis in the Diabetic Heart by Preventing Adverse Fibroblast and Macrophage Phenotype Changes.

Reduced levels of the sensory nerve neuropeptide substance P (SP) have been reported in the diabetic rat heart, the consequence being a loss of cardioprotection in response to ischemic post-conditioning. We considered whether this loss of SP also predisposes the heart to non-ischemic diabetic cardiomyopathy in the form of fibrosis and hypertrophy. We report that diabetic Lepr mice have reduced serum SP and that administration of exogenous replacement SP ameliorated cardiac fibrosis.

Identifying support mechanisms to overcome barriers to food safety scheme certification in the food and drink manufacturing industry in Wales, UK.

Obtaining food safety certification is essential for food manufacturers. Potential barriers to obtaining certification are complex, interrelated and broadly relate to, 'knowledge and skills', 'time, cost and resources', and 'communication and access to information'. This study aimed to explore requirements for support to enable food manufacturers in Wales to overcome identified barriers.
