Medical and Biotech [MESH] Definitions
Studies designed to examine associations, commonly, hypothesized causal relations. They are usually concerned with identifying or measuring the effects of risk factors or exposures. The common types of analytic study are CASE-CONTROL STUDIES; COHORT STUDIES; and CROSS-SECTIONAL STUDIES.
Confounding Factors (epidemiology)
Factors that can cause or prevent the outcome of interest, are not intermediate variables, and are not associated with the factor(s) under investigation. They give rise to situations in which the effects of two processes are not separated, or the contribution of causal factors cannot be separated, or the measure of the effect of exposure or risk is distorted because of its association with other factors influencing the outcome of the study.
A species of LENTIVIRUS, subgenus ovine-caprine lentiviruses (LENTIVIRUSES, OVINE-CAPRINE), that can cause chronic pneumonia (maedi), mastitis, arthritis, and encephalomyelitis (visna) in sheep. Maedi is a progressive pneumonia of sheep which is similar to but not the same as jaagsiekte (PULMONARY ADENOMATOSIS, OVINE). Visna is a demyelinating leukoencephalomyelitis of sheep which is similar to but not the same as SCRAPIE.
The relating of causes to the effects they produce. Causes are termed necessary when they must always precede an effect and sufficient when they initiate or produce an effect. Any of several factors may be associated with the potential disease causation or outcome, including predisposing factors, enabling factors, precipitating factors, reinforcing factors, and risk factors.
Demyelinating leukoencephalomyelitis of sheep caused by the VISNA-MAEDI VIRUS. It is similar to but not the same as SCRAPIE.
Scrapie, a fatal transmissible spongiform encephalopathy (TSE) occurs in two phenotypes: classical and atypical. Many authors point out that the polymorphism of three codons (136, 154, 171) of the PRN...
Susceptibility to natural scrapie in sheep is associated with polymorphisms at codons 136, 154 and 171 of the prion protein (PrP) gene. To assess the risk of scrapie in sheep raised in China, DNA from...
It is well known that scrapie is a fatal, neurodegenerative disease in sheep and goat, which belongs to the group of transmissible spongiform encephalopathies (TSEs) or prion diseases. It has been con...
ABSTRACT: Scrapie is a fatal neurodegenerative disorder of sheep and goats caused by post-translational conformational change in the host-encoded prion protein (PrPC). Susceptibility or resistance to...
The resistance or susceptibility of sheep to scrapie is associated with polymorphisms of the prion protein gene (PRNP), particularly, single nucleotide polymorphisms (SNPs) in amino acid positions 136...
The purpose of this study is to determine if improvements in mood will ameliorate autonomic dysregulation, HPA dysfunction and typical (e.g. lipids) and atypical risk factors in depressed...
The incidence rate of bladder cancer in the Barcelona area of Spain is almost identical to that of the U.S. Cigarette smoking has been identified as the most significant risk factor for b...
The objective of this study is to determine the breast cancer risk of Mirena® users compared to copper intrauterine device (IUD) users in a community-based case-control study.
This study will examine possible causes of metabolic side effects in people taking atypical antipsychotic (AAP) medications.
It would be useful to study coronary arteriovenous difference of various markers in patients who are undergoing coronary angiography for suspected coronary artery disease. Environmental an...
