Increased westernization with Japanese migration to the U. S. in the early 20th century is thought to have altered the risk of cardiovascular disease. Whether similar effects include changes in the risk of Parkinson’s disease (PD) is not clear. This report describes the relations between environmental, life-style, and physical attributes and the incidence(More)
PURPOSE The Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) study is one of the first population-based studies to integrate psychological, physiological, and subclinical measures of stress, disease, and mental dysfunction. This pilot study was undertaken to establish a methodology and descriptive results for a larger police study. METHODS A(More)
BACKGROUND Silicosis is characterized by fibrosing nodular lesions that eventually develop into progressive pulmonary fibrosis. Pro-inflammatory cytokines, such as interleukin-1 (IL-1), play a key role in the development of silicosis by regulating mediators which are responsible for lung injury, inflammation, and potentially fibrosis. To study whether(More)
Mobile radio systems for public safety and agencies engaged in emergency response and disaster recovery operations must support multicast voice traffic. In this paper, we analyze the distribution of call interarrival and call holding times for multicast voice (talk group) traffic on a transmission trunked mobile radio system. In such systems, the channel is(More)
CONTEXT Parkinson disease (PD) has an unknown cause; however, convincing evidence is emerging that indicates pesticides can selectively injure the dopaminergic system in laboratory animals. Retrospective studies in humans demonstrate a link between exposure to agricultural lifestyle factors and PD. OBJECTIVE To determine whether working on a plantation in(More)
OBJECTIVES This study examines cross-sectional associations of indices of adiposity, lean body mass, and physical activity, with heart rate variability (HRV), a marker for parasympathetic cardiac vagal control. METHODS The study population consists of 360 officers from the Buffalo New York Police Department. Indices of adiposity include body mass index,(More)
The Caerphilly Collaborative Heart Disease Study is based on a large cohort of men (2,398) aged 49-66 years at the time of study. Platelet aggregation induced by collagen, thrombin, and ADP was measured in fasting blood samples and was related to prevalent angina, past myocardial infarction, and electrocardiographic evidence of ischemic heart disease. A(More)
Intakes of alcohol and saturated fatty acids were determined through a dietary questionnaire from 1600 men (aged 49-66 y) in the Caerphilly Prospective Heart Disease Study. Platelet aggregation induced by thrombin adenosine disphosphate (ADP), and collagen was studied in subjects who had fasted and had not recently taken drugs affecting platelets. In(More)
This study describes the influence of muscle fiber type composition, enzyme activities and capillary supply on muscle strength, local muscle endurance or aerobic power and capacity. Muscle biopsies were obtained from m. vastus lateralis in thirteen physically active men. Histochemical staining procedures were applied to assess the percentage of fast twitch(More)
We examined 204 decedents of the autopsy component of the Honolulu-Asia Aging Study, a longitudinal cohort study, who had been clinically assessed for dementia. A sensitive ELISA technique was used to quantify glial fibrillary acidic protein (GFAP), a marker for astrogliosis, in four specific cortical brain regions and assess associations between GFAP and(More)
