The response of basilar arteries to noradrenaline varies among many animal species, but remains little studied in poultry. Accordingly, we aimed characterize the adrenergic receptor (AR) subtypes that modulate vascular chicken, with isometric recording arterial ring tension using an organ bath. We demonstrated presence both alpha and beta (α β) through evaluating noradrenaline, without a range β-AR α-AR antagonists. concentration-dependent relaxations then induced by agonists indicated...
People who drink naturally hardened water may experience longevity-enhancing effects. In this study, we investigated hardness and longevity from both geological epidemiological perspectives in Japan's Amami islands, where drinking is drawn coralline or non-coralline bedrock. We hardness, limestone bedrock occupancy, the centenarian rate (number per 10,000 population) by municipality across four adjacent islands (Amami-Oshima (non-coralline), Tokunoshima, Okinoerabu, Yoron (predominantly...
Processing with heat treatment has been reported to alter several therapeutic effects of turmeric. In Vietnamese traditional medicine, turmeric long used for bacterial infections, and roasting techniques are sometimes applied this material. However, there have no studies investigating the these thermal processes on plant’s antibacterial properties. Our study was therefore performed examine changes that produced Slices dried were further subjected light-roasting (80 °C in 20 min) or...
Vasoreactivity is relatively well documented in terrestrial snakes, but has previously been investigated only one semi-arboreal snake species. Consequently, the extent to which vasoreactivity common across taxa, or varies by habitat unclear. The Tokara habu (Protobothrops tokarensis) a endemic two small adjacent Japanese islands, and hence useful species for further investigation of vasoreactivity. We evaluated responses known vasoactive substances thoracic aortas isolated from habu. Under...

Gravity may exert species-specific effects on quadrupedal vasoreactivity, reflecting variations in the vertical displacement of cardiocranial axis from dorsal plane. Deer show markedly displaced axes compared to their closest phylogenetic relatives, but relative cerebrovascular responses remain unelucidated. Accordingly, we investigated noradrenaline (NA), acetylcholine (ACh), 5-hydroxytryptamine (5-HT), histamine, angiotensin (Ang) II, and bradykinin (BK) cervine basilar arterial rings. NA...
The basilar arterial endothelium mediates blood-vessel relaxation, partly through release of nitric oxide (NO). Apoptosis cerebrovascular endothelial cells is linked to high mortality rate in chickens infected with highly pathogenic avian influenza virus, but interestingly ducks exhibit greater resistance this virus. In study, we examined the responsiveness duck arteries (BAs) various vasoactive substances, including 5-hydroxytryptamine (5-HT), histamine (His), angiotensin (Ang) II,...
In reptiles, infection with Cryptosporidium parasite can be lethal, especially in species of family Eublepharidae such as Eublepharis macularius and Goniurosaurus splendes species. We investigated the presence spp. wild spp., five islands Japan. Nested PCR was performed to detect 38 fecal samples 9 reptile from Japan, 3 (3/8) positive kuroiwae sengokui Tokashikijima, Okinawa Prefecture were detected. A BLAST search detected gene sequences revealed that all identified serpentis, a...

Habu snakes (Protobothrops flavoviridis) are pit vipers found in the geographically adjacent but ecologically divergent islands of Tokunoshima and Amami-Oshima southwestern Japan. Abiotic factors can cause variation animal populations between two islands, may show such intraspecific physiological variation. We therefore evaluated vasoreactivity aortas isolated from both islands. showed significantly greater contractile responses to angiotensin (Ang) II, acetylcholine (ACh) noradrenaline,...
