Hydrogels for Three-Dimensional Ionizing-Radiation Dosimetry
2021
Radiation-sensitive gels are among the most recent and promising developments for radiation therapy (RT) dosimetry. RT dosimetry has the twofold goal of ensuring the quality of the treatment and the radiation protection of the patient. Benchmark dosimetry for acceptance testing and commissioning of RT systems is still based on ionization chambers. However, even the smallest chambers cannot resolve the steep dose gradients of up to 30–50% per mm generated with the most advanced techniques. While a multitude of systems based, e.g., on luminescence, silicon diodes and radiochromic materials have been developed, they do not allow the truly continuous 3D dose measurements offered by radiation-se…
Low-level environmental metal pollution is associated with altered gut microbiota of a wild rodent, the bank vole (Myodes glareolus)
2021
Mining and related industries are a major source of metal pollution. In contrast to the well-studied effects of ex-posure to metals on animal physiology and health, the impacts of environmental metal pollution on the gut mi-crobiota of wild animals are virtually unknown. As the gut microbiota is a key component of host health, it is important to understand whether metal pollution can alter wild animal gut microbiota composition. Using a combination of 16S rRNA amplicon sequencing and quantification of metal levels in kidneys, we assessed whether multi-metal exposure (the sum of normalized levels of fifteen metals) was associated with changes in gut microbiota of wild bank voles (Myodes glar…
Biodegradable Metal-Organic Framework-Based Microrobots (MOFBOTs).
2020
Microrobots and metal–organic frameworks (MOFs) have been identified as promising carriers for drug delivery applications. While clinical applications of microrobots are limited by their low drug loading efficiencies and the poor degradability of the materials used for their fabrication, MOFs lack motility and targeted drug delivery capabilities. The combination of these two fields marks the beginning of a new era; MOF‐based small‐scale robots (MOFBOTs) for biomedical applications. Yet, biodegradability is a major hurdle in the field of micro‐ and nanoswimmers including small‐scale robots. Here, a highly integrated MOFBOT that is able to realize magnetic locomotion, drug delivery, and selec…
Homeopātija – starp alternatīvo un biomedicīnas nozari Latvijā
2015
Homeopātija ir viena no populārākajām alternatīvās medicīnas praksēm Latvijā. Homeopātija ir ārstu papildspecialitāte, tāpēc visiem homeopātiem ir biomedicīnas izglītība. Pētījumā tiek pievērsta uzmanība ārstiem homeopātiem, kas apvieno biomedicīnu ar alternatīvo ārstniecības praksi, tādā veido tuvinot homeopātiju biomedicīnai. Pētījuma teorētiskajā daļā pētu robežas, kuras, apvienojot dažādās medicīnas specialitātes, tiek pārkonstruētas. Robežas tiek skatītas epistemioloģiskajā, leģitimitātes, profesionālās identitātes un organizatoriskajās dimensijās. Lai īstenotu pētījuma mērķi, tika veiktas intervijas ar ārstiem homeopātiem, kas praktizē homeopātiju, apvienojot to ar ģimenes ārsta vai p…
