Linking genetic and environmental factors in amphibian disease risk

Linking genetic and environmental factors in amphibian disease risk

A central question in evolutionary biology is how interactions between organisms and the environment shape genetic differentiation. The pathogen Batrachochytrium dendrobatidis (Bd) has caused variable population declines in the lowland leopard frog (Lithobates yavapaiensis); thus, disease has potentially shaped, or been shaped by, host genetic diversity. Environmental factors can also influence...

Environmental And Genetic Risk Factors For Bronchopulmonary Dysplasia In Neonates

Alcoholism and liver disease in Mexico: genetic and environmental factors.

Alcoholism and cirrhosis, which are two of the most serious health problems worldwide, have a broad spectrum of clinical outcomes. Both diseases are influenced by genetic susceptibility and cultural traits that differ globally but are specific for each population. In contrast to other regions around the world, Mexicans present the highest drinking score and a high mortality rate for alcoholic l...

Genetic and environmental factors in the development of Behcet's disease.

Analysis of HLA antigens and case control study were performed in 50 patients with Behcet's disease. Frequency of HLA-Bw51 was significantly increased in the patients (52.0%) as compared to that in the control subjects (16.0%). In case control study, the incidence of tonsillitis, and use of public bath and a privy were more frequently seen in the patients than in the controls. The patients were...

Genetic and environmental risk factors for Parkinson's disease in a Chinese population.

An epidemiological study of the environmental and genetic factors as well as the possible interplay between them was conducted among 215 patients with Parkinson's disease and 313 controls in a Chinese population in Hong Kong. In univariate analysis, a regular tea drinking habit was found to be a protective factor, which had not been reported before. Smoking (a protective factor), family history...
