Maya Worldviews at Conquest examines Maya culture and social life just prior to contact and the effect the subsequent Spanish conquest, as well as contact with other Mesoamerican cultures, had on the ...Maya worldview. Focusing on the Postclassic and Colonial periods, Maya Worldviews at Conquest provides a regional investigation of archaeological and epigraphic evidence of Maya ideology, landscape, historical consciousness, ritual practices, and religious symbolism before and during the Spanish conquest. Through careful investigation, the volume focuses on the impact of conversion, hybridization, resistance, and revitalization on the Mayans' understanding of their world and their place in it. The volume also addresses the issue of anthropologists unconsciously projecting their modern worldviews on the culture under investigation. Thus, the book critically defines and strengthens the use of worldviews in the scholarly literature regardless of the culture studied, making it of value not only to Maya scholars but also to those interested in the anthropologist's projection of worldview on other cultures in general.
To define biventricular diastolic behaviour in patients with cardiomyopathies with predominant diastolic left ventricular (LV) dysfunction.
Doppler tissue echocardiography and both mitral and ...tricuspid Doppler inflow profiles were investigated in hypertrophic (n = 17), hereditary hemochromatosis (n = 12) cardiomyopathies and age-matched normals (n = 31). The cardiomyopathy group had both lower early diastolic mitral lateral annular (El), cm/s (13.9 +/- 6.5) and medial (Em) (10.0 +/- 4.5) velocities compared with normals (19.5 +/- 5.5, 15.9 +/- 3.4, p < 0.01, respectively). In the cardiomyopathy group, late isovolumic relaxation myocardial velocity gradient (IVR-MVG) (s(-1)) was positive compared with negative in normals (1.3 +/- 1.3 vs. -0.7 +/- 1.4, p < 0.01, respectively). In both the cardiomyopathy group and in normals the onset of the tricuspid E-wave preceded the onset of the mitral E-wave. However, the onset of early diastolic tricuspid annular (Et) motion preceded the onset of El (ms) only in normals, but not in the cardiomyopathies (43 +/- 26 vs. -8 +/- 44, p < 0.01, respectively). In the cardiomyopathy group there was a positive correlation between the onset of Et and abnormally positive late IVR-MVG (r = 0.51, p = 0.002).
Biventricular early diastolic behaviour is abnormal in the selected group of cardiomyopathy patients. The delay in the Et (early diastolic longitudinal right ventricular relaxation) may have a negative effect on LV diastolic function.
