It has been asserted that employment as a welder is associated with an excess risk for the neurological disorder of manganism and development of Parkinson’s disease at an earlier than usual age. It has been suggested that this may be due to absorption of manganese in emissions from welding processes. In this two part paper sources of exposure to manganese, its role in human health and its toxic...

Research of natural environments often requires extensive field studies beyond the capacity of a single individual. In CONE Welder, we explore harnessing the power of human computation to aid ongoing research on avian activity and possible links to climate changes. Our approach utilizes a singly deployed pan-tilt-zoom web camera to gather observational data. The camera supports multiple operato...

INTRODUCTION Manganese regulates many enzymes and is essential for normal development and body function. Chronic manganese intoxication has an insidious and progressive course and usually starts with complaints of headache, fatigue, sleep disturbances, irritability and emotional instability. Later, several organ systems may be affected and, due to neurotoxicity, an atypical parkinsonian syndrom...

One hundred twenty-three of 300 blood samples (41%) taken from Rio Grande wild turkeys (Meleagris gallopavo intermedia) from three locations in southern Texas (Welder Wildlife Refuge, Chaparrosa Ranch, and Campo Alegre Ranch) and subinoculated into domestic broad-breasted white turkey poults were positive for a Plasmodium (Novyella) sp. Analysis of blood films from 350 turkeys revealed Haemopro...

BACKGROUND Welders are at risk for cardiovascular disease. Recent studies linked tobacco smoke exposure to hypomethylation of the F2RL3 (coagulation factor II (thrombin) receptor-like 3) gene, a marker for cardiovascular disease prognosis and mortality. However, whether welding fumes cause hypomethylation of F2RL3 remains unknown. METHODS We investigated 101 welders (median span of working as...
