Emerging infectious diseases are a key threat to conservation and public health, yet predicting and preventing their emergence is notoriously difficult. We devised a predictive model for the introduction of a zoonotic vector-borne pathogen by considering each of the pathways by which it may be introduced to a new area and comparing the relative risk of each(More)
Previous studies suggest that olfactory cues from damaged and fermented fruits play important roles in resource recognition of polyphagous spotted wing Drosophila flies (SWD), Drosophila suzukii (Matsumura) (Diptera: Drosophilidae). They are attracted to fermented sweet materials, such as decomposing fruits but also wines and vinegars, and to ubiquitous(More)
Recently, the novel dihydropyridine derivates YC-170, CGP 28392, and BAY K 8644 have been reported to act in the opposite way to Ca2+-entry blockers. We have found that these compounds inhibit the binding of [3H]nitrendipine on guinea pig heart membranes (Ki: 6 nM BAY K 8644, 115 nM CGP 28392 and 690 nM YC-170). Like those of nifedipine (Ki 1 nM), the(More)
Angiotensin II (AII) has been implicated as an important factor in the pathophysiology of heart diseases. Following the recent identification of two subtypes of the AII receptor in cardiac tissue of animals, we investigated the possible occurrence of these, or similar, subtypes in human atrial tissue. In right-atrial tissue from patients undergoing heart(More)
All the components of the renin-angiotensin system have been identified in the heart including the angiotensin II receptor subtypes AT1 and AT2. In the normal human heart, there is a decreasing receptor density from the right atrium to the left ventricle. In right atrial membranes prepared from pathological hearts, the percentage of AT1 receptor decreases(More)
Although the action of angiotensin-II (Ang-II) is believed to be mediated by a transmembrane signal transduction mechanism, accumulating evidence suggests that Ang-II may also have a direct nuclear action. We have characterized the nuclear Ang-II-binding site in purified nuclei preparation from rat liver and compared it to plasma membrane Ang-II receptors.(More)
Angiotensin II has two major receptor subtypes, designated AT1 and AT2. Both have been detected in the heart of several species, but most of the known functions of angiotensin II seem to be mediated through the AT1 receptor. The major objective of this study was to specify the cell type on which the AT2 receptor is located in the atrium of human heart.(More)
CGP 28392, a novel compound structurally related to the dihydropyridine Ca2+-entry blockers, causes a dose-dependent increase in intracellular free Ca2+ in human platelets, as measured with the Quin-2 Ca2+ indicator, with a semimaximal effective concentration of 2.2 X 10(-7) M. This effect occurs in a concentration range in which CGP 28392 competes for(More)
This study examines the effects of angiotensin II on hypertrophy and proliferation of aortic smooth muscle cells from spontaneously hypertensive and Wistar-Kyoto rats and the receptor subtypes mediating these effects. In quiescent confluent cells, angiotensin II induced a dose-dependent increase in thymidine and leucine incorporation without stimulating(More)
