OLHA (N-oleoylhistamine) modulates activity of mouse brain histaminergic neurons
Histaminergic (HA) neurons are located in the tuberomamillary nucleus (TMN) of the posterior hypothalamus, from where they project throughout the whole brain to control wakefulness. We examined the effects of Nα-oleoylhistamine (OLHA), a non-enzymatic condensation product of oleic acid (OLA) and histamine, on activity of mouse HA neurons in brain slices. OLHA bidirectionally modulated the firing of HA neurons. At 10 nM OLHA inhibited or had no action, whereas at 1 μM it evoked excitatory and inhibitory responses. Inhibition was not seen in presence of the histamine receptor H3 (H3R) antagonist clobenpropit and in calcium-free medium. Pre-incubation with a histamine-reuptake blocker prevented the decrease in firing by OLHA. OLHA-evoked increase in firing (EC50 ∼44 nM) was insensitive to blockers of cannabinoid 1 and 2 receptors and of the capsaicin receptor, but was significantly impaired by the peroxisome proliferator-activated receptor-alpha (PPAR-alpha) antagonist MK886, which suppressed also the rise in intracellular calcium level caused by OLHA. The OLHA-evoked excitation was mimicked by synthetic PPAR-alpha agonists (gemfibrozil and GW7647) and was abolished by the PKA inhibitor H-89. The H3R affinity (Ki) for histamine, measured in HEK293 cells with stable expression of human H3R, was higher than for OLHA (Ki: 42 vs 310 nM, respectively). Expression of PPAR-alpha was not different between TMN regions of males and females, responses to OLHA did not differ. Molecular modelling of PPAR-alpha bound to either OLHA or OEA showed similar binding energies. These findings shed light on a novel biotransformation product of histamine which may play a role in health and disease

Urban Administrative Reforms of Princess Olha (1)
Статтю присвячено дослідженню фрагмента літописної статті 947 року про встановлення київською княгинею Ольгою погостів у Новгородській землі. Автор доводить, що первісний текст є штучно прив’язаним до північної Новгородщини. Натомість його слід розглядати в контексті подій на Південному Заході Русі, спровокованих київсько-древлянською війною.The article discusses a fragment of the 947 chronicle text. It describes an episode when Princess Olha establishes the pohosts on the Novhorod lands. The author argues that the primary text was artificially attached to the Northern Novhorodshchyna; however, it should be considered in context of the development on the south-western part of Rus which was precipitated by the Kyiv-Drevlyanian war

European Politics and Society: Václav Havel Joint Master Programme Charles University The EU response to the development in Belarus in 2021: the human rights scope Master's Thesis Abstract Author: Olha Kotielnikova Supervisor: Mgr. Daniela Kolenovská, Ph.D. Year of defence: 2022 Length of the thesis: 18892 words Abstract Human rights abuse in Belarus has again become a topical issue on the European Union's agenda alongside political rights violations since 2020. The Union sees its role in influencing the internal policy of the proclaimed Belarusian government for it to start respecting human rights. As a united body, it has instruments to exercise its foreign policy instruments, such as restrictive measures, negotiations, and communication. The dynamics of their usage have been changing, but there is still potential to review and adapt possible European responses.
