Photodynamics of a Molecular Water-Soluble Nanocluster Identified as Au130(pMBA)50
2015
Photodynamics of a highly monodisperse sample of a water-soluble gold nanocluster tentatively identified as Au130(pMBA)50 (pMBA = p-mercaptobenzoic acid) was studied by mid-IR transient absorption spectroscopy with visible excitation. The observed long-lived excited states (>1 ns) indicate a molecular behavior of the cluster. By combining the transient absorption data with DFT calculation results the observed relaxation dynamics could be fully explained by identifying several relaxation processes involving singlet and triplet manifolds. The results indicate that the cluster may have interesting transient magnetic properties due to a long-lived triplet population.

Resveratrol post-transcriptionally regulates pro-inflammatory gene expression via regulation of KSRP RNA binding activity
2014
Resveratrol shows beneficial effects in inflammation-based diseases like cancer, cardiovascular and chronic inflammatory diseases. Therefore, the molecular mechanisms of the anti-inflammatory resveratrol effects deserve more attention. In human epithelial DLD-1 and monocytic Mono Mac 6 cells resveratrol decreased the expression of iNOS, IL-8 and TNF-α by reducing mRNA stability without inhibition of the promoter activity. Shown by pharmacological and siRNA-mediated inhibition, the observed effects are SIRT1-independent. Target-fishing and drug responsive target stability experiments showed selective binding of resveratrol to the RNA-binding protein KSRP, a central post-transcriptional regul…
Molecular Approaches Fighting Nonsense
2021
Nonsense mutations are the result of single nucleotide substitutions in the DNA that change a sense codon (coding for an amino acid) to a nonsense or premature termination codon (PTC) within the coding region of the mRNA [...]

Maintenance costs of male dominance and sexually antagonistic selection in the wild
2018
Variation in dominance status determines male mating and reproductive success, but natural selection for male dominance can be detrimental or antagonistic for female performance, and ultimately their fitness. Attaining and maintaining a high dominance status in a population of competing individuals is physiologically costly for males. But how male dominance status is mediated by maintenance energetics is currently not well understood, nor are the corresponding effects of male energetics on his sisters recognized. We conducted laboratory and field experiments on rodent populations to test whether selective breeding for male dominance status (dominant vs. subordinate breeding lines) antagonis…

1H, 13C and 15N NMR chemical shift assignments of cAMP-regulated phosphoprotein-19 and -16 (ARPP-19 and ARPP-16)
2020
Protein Phosphatase 2A, PP2A, the principal Serine/threonine phosphatase, has major roles in broad range of signaling pathways that include regulation of cell cycle, cell proliferation and neuronal signaling. The loss of function of PP2A is linked with many human diseases, like cancer and neurodegenerative disorders. Protein phosphatase 2A (PP2A) functions as tumor suppressor and its tumor suppressor activity is inhibited by the overexpression of PP2A inhibitor proteins in most of the cancers. ARPP-19/ARPP-16 has been identified as one of the potential PP2A inhibitor proteins. Here, we report the resonance assignment of backbone 1H, 13C and 15N atoms of human ARPP-19 and ARPP-16 proteins.

Ļaunprātīgas rīcības jēdziens Ženēvas 1956. gada 19. maija Konvencijā "Par kravu starptautisko autopārvadājumu līgumu (CMR)."
2015
CMR konvencijā pārvadātāju atbildība par pilnīgu vai daļēju kravas zaudējumu ir ierobežota. Tomēr 29. pantā ir ietverts izņēmums, kad pārvadātāja atbildība netiek ierobežota. 29. panta redakcija pieļauj ļoti atšķirīgu izpratni attiecībā uz to, kādos gadījumos pārvadātājs ir jāatbrīvo no atbildības. Darba mērķis ir padziļināti izpētīt ļaunprātīgas un tai pielīdzināmas rīcības jēdziena saturu, salīdzinot jēdziena izpratni Rietumeiropas valstīs un Latvijā. Darba ietvaros autors veiks konvencijas 29. panta teleoloģiskā un vēsturisko interpretāciju, kā arī aplūkos un analizēs valstu tiesu praksi 29. panta piemērošanā. Darba rezultāts ir izstrādāts pētījums, kurā ir uzskatāmi salīdzināta valstu i…
