We have used the Rat Atlas cDNA Array ("BD Bioscience") to assess changes in mRNA expression of 588 genes in rat brain after acute treatment of 2-aminoadamantane compound--Ladasten. Drug exhibits the psychostimulating and anxyolitic actions. The analysis of results of hybridization on macrochips and their corroboration by quantitative real-time RT-PCR has allowed to reveal 12 genes, expression of which changes in response to ladasten in rat brain cells. The GAT3 and CARBH genes should be considered as primary pharmacologically significant targets and the changes of their functional conditions allows to explain the distinct mechanisms of anxyolitic properties of the drug. It was shown that Ladasten induced genes are involved in the different signalling pathways (APC, Rb, PKCIP, PMCA), genes encoding the cytosceletal proteins (Tubal, actin), synaptic proteins (Syn IA&IB, PLP) and metabolism enzymes (Gapdh, NSE). It is possible to assume, that proteins, encoded by the given genes participate in the compensatory and/or neuroplastic adaptation to biochemical effects of Ladasten.

Introduction: Grafts with alcohol-associated liver disease (ALD) subjected to prolonged cold ischaemia from donors after brain death (DBD) are typically unsuitable for transplantation. Here, we investigated the role of growth hormone (GH) in livers with ALD from DBDs and its relationship with vascular endothelial growth factor A (VEGFA) and VEGFB.
Methods: Livers from rats fed ethanol for 6 weeks and with brain death (BD) were cold stored for 24 h and subjected to reperfusion.

Introduction: Access to electric light has exposed living organisms to varying intensities of light throughout the 24 h day. Dim light at night (DLAN) is an inappropriate signal for the biological clock, which is responsible for the circadian organization of physiology. During the gestational period, physiological adaptations occur to ensure a successful pregnancy and optimal fetal development.

Significance: Women are at increased risk for mood disorders, which may be partly attributed to exposure to endocrine-disrupting chemicals (EDCs) during sensitive periods such as pregnancy. Exposure during these times can impact brain development in the offspring, potentially leading to mood disorders in later life. Additionally, fluctuating levels of endogenous estrogens, as seen during pregnancy, or the use of oral contraceptives, can further elevate this risk.

Our study aimed to investigate vertebral bone marrow perfusion using dynamic contrast-enhanced (DCE) MRI with a pharmacokinetic model. We also measured possible changes in water and fat content and bony trabeculae using T2* quantification, MR spectroscopy (MRS), and microcomputed tomography (μCT).

Introduction: We aimed to investigate the effects of central kisspeptin-10 and p234 administration on basal brain activity and epilepsy-like conditions induced by 4-aminopyridine (4-AP), as well as their roles in the electrocorticogram (ECoG) power spectrum and EEG waves.
Methods: Thirty-five male Wistar rats were divided into five groups: sham,4-AP (2.5 mg/kg i.
