From anti-fouling to biofilm inhibition: New cytotoxic secondary metabolites from two Indonesian Agelas sponges
2010
Chemical investigation of Indonesian marine sponges Agelas linnaei and A. nakamurai afforded 24 alkaloid derivatives representing either bromopyrrole or diterpene alkaloids. A. linnaei yielded 16 bromopyrrole alkaloids including 11 new natural products with the latter exhibiting unusual functionalities. The new compounds include the first iodinated tyramine-unit bearing pyrrole alkaloids, agelanesins A-D. These compounds exhibited cytotoxic activity against L5178Y mouse lymphoma cells with IC(50) values between 9.25 and 16.76 muM. Further new compounds include taurine acid substituted bromopyrrole alkaloids and a new dibromophakellin derivative. A. nakamurai yielded eight alkaloids among th…
Cool barnacles: Do common biogenic structures enhance or retard rates of deterioration of intertidal rocks and concrete?
2017
Sedentary and mobile organisms grow profusely on hard substrates within the coastal zone and contribute to the deterioration of coastal engineering structures and the geomorphic evolution of rocky shores by both enhancing and retarding weathering and erosion. There is a lack of quantitative evidence for the direction and magnitude of these effects. This study assesses the influence of globally-abundant intertidal organisms, barnacles, by measuring the response of limestone, granite and marine-grade concrete colonised with varying percentage covers of Chthamalus spp. under simulated, temperate intertidal conditions. Temperature regimes at 5 and 10 mm below the surface of each material demons…
Living on the Edge: Settlement Patterns by the Symbiotic Barnacle Xenobalanus globicipitis on Small Cetaceans
2015
The highly specialized coronulid barnacle Xenobalanus globicipitis attaches exclusively on cetaceans worldwide, but little is known about the factors that drive the microhabitat patterns on its hosts. We investigate this issue based on data on occurrence, abundance, distribution, orientation, and size of X. globicipitis collected from 242 striped dolphins (Stenella coeruleoalba) that were stranded along the Mediterranean coast of Spain. Barnacles exclusively infested the fins, particularly along the trailing edge. Occurrence, abundance, and density of X. globicipitis were significantly higher, and barnacles were significantly larger, on the caudal fin than on the flippers and dorsal fin. Ba…
Datortomogrāfijas protokola pielietojums pacientiem ar thoracic outlet sindromu
2021
Bakalaura darba tēmas “Datortomogrāfijas protokola pielietojums pacientiem ar thoracic outlet sindromu” darba mērķis ir noskaidrot datortomogrāfijas protokola pielietošanas iespējas pacientiem ar thoracic outlet sindromu Latvijā. Aktualitāte saistīta ar thoracic outlet sindroma sarežģīto diagnostiku. Vairumā gadījumu par šo sindromu aizmirst, kā dēļ netiek veikta atbilstoša diagnostika, patoloģijas atklāšanai. Līdz ar to pacients nesaņem savlaicīgu ārstēšanu, bet neārstēts sindroms rada neatgriezeniskus fiziskus un psihiskus traucējumus. Thoracic outlet sindroms ir nopietna, dzīves kvalitāti kropļojoša slimība, kas sāpju sindroma dēļ pacientiem rada psihiskus traucējumus. Neārstējot šo sind…
