Gut bacterial tyrosine decarboxylases restrict levels of levodopa in the treatment of Parkinson’s disease

By |2019-01-20T00:46:23+00:00January 20th, 2019|

Abstract Human gut microbiota senses its environment and responds by releasing metabolites, some of which are key regulators of human health and disease. In this study, we characterize gut-associated bacteria in their ability to decarboxylate levodopa to dopamine via tyrosine decarboxylases. Bacterial tyrosine decarboxylases efficiently convert levodopa to dopamine, even in the presence of tyrosine, [...]

Short-term consumption of a high-fat diet increases host susceptibility to Listeria monocytogenes infection

By |2019-01-20T00:24:04+00:00January 20th, 2019|

Background A westernized diet comprising a high caloric intake from animal fats is known to influence the development of pathological inflammatory conditions. However, there has been relatively little focus upon the implications of such diets for the progression of infectious disease. Here, we investigated the influence of a high-fat (HF) diet upon parameters that influence Listeria [...]

Air Pollution damages brains, as well as hearts and lungs

PM2.5 pollution – 9 million premature deaths a year The vast majority of pollution-related deaths are linked to fine particles less than 2.5 millionths of a metre (known as PM2.5).  PM2.5 behave like gases and, like the air we need to breathe, enter our homes even when all doors and window are shut.   [...]

Chemical Exposure in Healthcare Differs by Task and Product

By |2019-01-20T00:11:48+00:00January 20th, 2019|

Cleaning and disinfecting products are complex mixtures of chemicals that can irritate the skin. Evidence also shows that exposure to these products may increase the risk of work-related asthma among healthcare workers. But the effects of specific chemicals remain unclear. Now, a NIOSH study published in the journal Annals of Work Exposures and Health has added to [...]

Risk of Mining-related Lung Disease Varies by Region, Mine Type, and Safety Observance

By |2019-01-19T23:53:29+00:00January 19th, 2019|

With the recent resurgence of the most severe form of black lung disease among coal miners, especially in central Appalachia, understanding and preventing exposure to the respirable, or inhalable, dust generated during the extraction of coal is paramount.  Black lung is a form of pneumoconiosis, or scarring lung disease, caused by breathing in dust that [...]
