Inhibition of gluconeogenesis by extracellular ATP in isolated rat hepatocytes.
1991
The aim of this study was to determine the effect of externally added ATP on gluconeogenesis by isolated hepatocytes from starved rats. High concentrations of extracellular ATP inhibited gluconeogenesis from lactate and pyruvate but not from glycerol or fructose. This inhibition was associated with an increase in intracellular adenosine contents. ADP, AMP, or adenosine but not guanosine 5'triphosphate, inosine 5' triphosphate, or adenine also inhibited gluconeogenesis. alpha, beta-Methylene-ATP, a nonmetabolizable structural analogue of ATP, did not affect the rate of gluconeogenesis. Intracellular ATP levels were increased by externally added ATP or adenosine, but ATP-to-ADP ratios in the…
Brominated flame retardants and organochlorines in the European environment using great tit eggs as a biomonitoring tool
2009
Large-scale studies are essential to assess the emission patterns and spatial distribution of organohalogenated pollutants (OHPs) in the environment. Bird eggs have several advantages compared to other environmental media which have previously been used to map the distribution of OHPs. In this study, large-scale geographical variation in the occurrence of OHPs, such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs) and organochlorine pesticides (OCPs), was investigated throughout Europe using eggs of a terrestrial residential passerine species, the great tit (Parus major). Great tit eggs from 22 sampling sites, involving urban, rural and remote areas, in 14 Europea…

ES enerģētikas diplomātija: veids, kā orientēties enerģētikas jomā Zaļā darījuma laikmetā
2021
The European Green Deal encompasses two aspects spanning across the internal-external continuum. Firstly, to achieve climate neutrality, the EU energy sector will undergo a complete transformation and, consequently, play an essential role in the bloc’s transition to a cleaner economy. Secondly, the Green Deal provides the EU with an impeccable opportunity to play a more assertive role in international politics. In this context, energy diplomacy becomes a vital tool for the EU’s objectives. The papers argue that energy diplomacy can help the EU respond to its overall energy situation. In order to answer the research question, first, the EU energy situation has been systematically studied thr…
Electronic structure of the ytterbium monohydroxide molecule to search for axionlike particles
2021
Recently, the YbOH molecule has been suggested as a candidate to search for the electron electric dipole moment (eEDM), which violates spatial parity ($P$) and time-reversal ($T$) symmetries [I. Kozyryev and N. R. Hutzler, Phys. Rev. Lett. 119, 133002 (2017)]. In the present paper, we show that the same system can be used to measure coupling constants of the interaction of electrons and nucleus mediated by axionlike particles. The electron-nucleus interaction produced by the axion exchange can contribute to a $T,P$-violating EDM of the whole molecular system. We express the corresponding $T,P$-violating energy shift produced by this effect in terms of the axion mass and product of the axion…
Rietumu pasaule modernajos laikos: vēstures problēmas
2019
Latvijas Universitātes asociētais profesors, vēstures doktors Jānis Taurēns par grāmatu: "Bija patiess prieks strādāt ar manas mentores un kolēģes akadēmiskajā pasaulē profesores Lilitas Zemītes grāmatu, kas ir spilgti uzrakstīta. Laikā, kad visu planētu pārpludina mērķtiecīgi izplatītas šaubas par Rietumu pasaules vērtībām, civilizācijas un dzīvesveida dzīvotspēju, ir svarīgi atkal un atkal atgādināt par tās skaistumu, krāsainību un bezgala interesanto vēsturi." Savukārt Latvijas diplomāts, vēstures maģistrs Jānis Beķeris, raksturojot Lilitu Zemīti, saka: "Profesore ir no ļoti nedaudzajiem vēsturniekiem Latvijā, kas ar tik lielu un patiesu aizrautību pievērsusies Rietumu pasaules vēsturei …
Intervenir à titre privé dans la diplomatie de sa cité : l'exemple de la paix de Nicias chez Thucydide
2013
Act on private basis in diplomacy of one’s own city. The example of Nicias’ peace in Thucydides. During the diplomatic exchanges related at the beginning of the fifth book, Thucydides shows two explicit private interventions using words connected with idia. First, two ephores, Cleoboulos and Xenares, make private propositions. Then, an Athenian, Alcibiades sends a private messenger. Whereas these two actions are unique in the fifth book, because Thucydides’ vocabulary is specific, some other citizens express opinions different from the majority decisions. Some of them act against the policy of their City. Self-interest may incite some citizens to participate in civic action, and the private…
Investigation of the hyperfine structure of weak atomic Vanadium lines by means of Fourier transform spectroscopy
2015
In continuation of our work on the investigation of the hyperfine structure (HFS) of atomic vanadium, we analyzed weak spectral lines in a Fourier transform spectrum that have not been investigated up to now. The main objective of this work was the determination of the magnetic dipole HFS constant A of the energy level at 15 103.784 cm−1, which was the only energy level with unknown A value up to the energy of 28 000 cm−1. Additionally, other gaps in the data of magnetic dipole HFS could be filled in. The spectrum of vanadium–argon plasma in a hollow cathode lamp is recorded in the spectral range from 12 500 to 26 000 cm−1 or 800 to 380 nm, respectively. The HFS of 42 weak atomic vanadium l…
Association between use of novel glucose-lowering drugs and COVID-19 hospitalization and death in patients with type 2 diabetes: a nationwide registr…
2022
Abstract Aims Type 2 diabetes (T2DM) in patients with coronavirus disease-19 (COVID-19) is associated with a worse prognosis. We separately investigated the associations between the use of sodium-glucose cotransporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1 RA), and dipeptidyl peptidase-4 inhibitors (DPP-4i), and the risk of COVID-19 hospitalization and death. Methods and results Patients with T2DM registered in the Swedish National Patient Registry and alive on 1 February 2020 were included. ‘Incident severe COVID-19’ was defined as the first hospitalization and/or death from COVID-19. A modified Poisson regression approach was applied to a 1:1 propensity sc…
Effects of Beclomethasone dipropionate and Formoterol in reducing oxidative stress induced by cigarette smoke extracts and IL-17
2011
Rationale: Oxidative stress is involved in airway inflammatory diseases. Inhaled-corticosteroids reduce airway inflammation and the combination with long-acting β2 agonists enhances this effect. Objective: to investigate whether Cigarette smoke extracts (CSE) and Interleukin-17A (IL-17A) activate airway epithelial cells to release markers of oxidative/nitrosative stress and to investigate the effect of beclomethasone dipropionate (BDP) and formoterol. Methods: Human bronchial epithelial cells (16HBE) were stimulated with different concentrations of CSE (from 0 to 10%) to evaluate the expression of IL-17 receptor (IL-17R). 16HBE were also stimulated with CSE (2.5%) with and withouth rhIL-17A…
