An evaluation about the bioecology of the Rhopalurus junceuses (Herbst 1800)-( Scorpiones: Buthidae) population in El Pitirre locality, Los Palacios municipality, Pinar del Río, is presented, due to the field studies carried out during two months of low pluvious period in Cuba ( February and March 2013 ). The field works was made by means of the establishment of five rectangular plots of 800 m2 each one, covering a total sampling area of 4000 m2. As criterions of the current states of the population could conclude that in El Pitirre locality, represented for an ecosystem of low and very altered mountain by different types of disturbances, the present population of R. junceuses show values of high abundance, by surpassing the 112 individuals by hectare in February and 145 in March; the population is structured for a bigger representatives of juvenile individuals that in all sampling surpasses the 50% in respect to the total census; it is a significant evidence about the replacement availability in the population and a capacitance to guarantee its maintenance in spite of the grateful disturbances., Se presenta la evaluación de la bioecología de la población de Rhopalurus junceus (Herbst 1800) - (Scorpiones: Buthidae) en la localidad El Pitirre, municipio Los Palacios, Pinar del Río, a partir de estudios de campo realizados durante los meses febrero y marzo de 2013. El trabajo de campo se hizo mediante el establecimiento de cinco parcelas rectangulares de de 800 m2 cada una, cubriendo un área de muestreo total de 4000 m2. Como criterios del estado actual de la población se pudo concluir que en el área, representada por un ecosistema de premontaña baja, muy alterada por diferentes tipos de perturbaciones, la población presente de R. junceus muestra valores de abundancia elevados, superando los 112 individuos por hectárea en febrero y 145 en marzo; la población se estructura por una mayor representatividad de individuos juveniles que en todos los muestreos supera el 50% respecto al total censado; lo anterior evidencia una alta disponibilidad de reemplazo en la población y una capacidad para garantizar su mantenimiento a pesar de las perturbaciones reconocidas.

Intra-aortic balloon counterpulsation (IABC) can improve post-myocardial infarction (MI) outcomes, but the mechanisms of such effect remain unclear. We hypothesized that IABC augmentation reduces the extent of microvascular obstruction after acute infarction.

Left ventricular (LV) relaxation entails myocardial deformation that induces LV filling. Yet, the precise mechanisms of the earliest changes in tissue properties that characterize myocardial relaxation remain incompletely understood. Ten healthy volunteers (seven males), 25-43 yr, underwent tagged and cine MRI with high temporal resolution (25-35 ms). Normal strains including radial (E(rr)), circumferential (E(cc)), and longitudinal (E(ll)) strains, shear strains including E(cl) (circumferential-longitudinal), E(cr) (circumferential-radial), and E(rl) (radial-longitudinal), and principal strains (E(1), E(2), and E(3)) were calculated using a displacement field-fitting method. Temporal changes in angular strains indicative of shear and torsion release and normal strains were studied during late systole and early relaxation. The onset of individual relaxation strains was heterogeneous relative to LV filling. Shear strains (E(cr), E(rl), and E(cl)) and radial thinning were first to develop. Times of onset of E(cr), E(rl), E(cl), and E(rr) occurred 108, 93, 67, and 73 ms before aortic valve closure, respectively. E(ll), E(cc), and LV volume change commenced significantly later after the onset of diastolic shear strains and radial thinning. The onset of E(cc), E(ll), and LV volume change was noted 38 ms before aortic valve closure (P < or = 0.05 relative to the onset of shear strains and E(rr)). Myocardial relaxation is characterized by a three-dimensional unfolding deformation that includes release of torsion, shear, and radial thinning beginning before aortic valve closure. This unfolding pattern precedes longitudinal and circumferential elongation and may facilitate early diastolic filling.

Because ECG alterations caused by ischemia cannot be reliably detected in the high-field MRI environment, detection of wall motion abnormalities is often used to ensure patient safety during stress testing. However, an experienced observer is needed to detect these abnormalities. In this study, we investigate the use of fast harmonic phase (FastHARP) MRI for the quantitative, operator-independent detection of the onset of ischemia during acute coronary occlusion.

Because ECG alterations caused by ischemia cannot be reliably detected in the high-field MRI environment, detection of wall motion abnormalities is often used to ensure patient safety during stress testing. However, an experienced observer is needed to detect these abnormalities. In this study, we investigate the use of fast harmonic phase (FastHARP) MRI for the quantitative, operator-independent detection of the onset of ischemia during acute coronary occlusion. Eight mongrel dogs underwent an acute 2-minute closed-chest coronary artery occlusion while continuous FastHARP images were acquired. Full regional wall strain was determined every other heartbeat in a single short-axis imaging slice. After 5 minutes of reperfusion, a second 2-minute ischemic episode was induced during the acquisition of conventional cine wall-motion images. The time at which ECG alterations were observed during the first ischemic period was recorded. The time from occlusion to the detection of ischemia, based on a consensus of 2 blinded observers, was determined for MRI. No significant ischemia was present in 2 animals. In the remaining animals, the onset of ischemia was detected significantly earlier by FastHARP than by cine MRI (9.5+/-5 versus 33+/-14 seconds, P<0.01). HARP ischemia detection preceded ECG changes, on average, by 54 seconds. The rapid acquisition and detection of induced ischemia with FastHARP MRI shows promise as a nonsubjective method to diagnose significant coronary lesions during MR stress testing.
