Power spectra in the 3 cohorts were compared using one-way analysis of variance (ANOVA), and power spectra images were compared using T-contrast tests. A post hoc analysis compared peak alpha power between the groups.

Compared with controls, participants with IGE had higher interictal EEG spectral power in the delta band in the midline central region, in the theta band in the midline, in the beta band over the left hemisphere, and in the gamma band over right hemisphere and left central regions. There were no differences in spectral power between cohorts with WC-IGE and DR-IGE. Peak alpha power was lower in WC-IGE and DR-IGE than controls.

Electroencephalography spectral power analysis could form part of a clinically useful diagnostic biomarker for IGE; however, it did not correlate with response to AED in this study.

Evaluating the different molecular interactions by quantum mechanics calculations is not a simple task, since formation of an L-R complex is a dynamic process. In this case, the use of combined techniques of molecular dynamics (MD) and quantum calculations is one the best possible approaches. In this work we report a comparative study using combined MD and QTAIM (Quantum Theory of Atoms In Molecules) calculations for five biological systems with different levels of structural complexity. We have studied Acetylcholinesterase (AChE), D2 Dopamine Receptor (D2DR), beta Secretase (BACE1), Dihydrofolate Reductase (DHFR) and Sphingosine Kinase 1 (SphK1). In these molecular targets, we have analyzed different ligands with diverse structural characteristics. The inhibitory activities of most of them have been previously measured in our laboratory. Our results indicate that QTAIM calculations can be extremely useful for in silico studies. It is possible to obtain very accurate information about the strength of the molecular interactions that stabilize the formation of the different L-R complexes. Better correlations can be obtained between theoretical and experimental data by using QTAIM calculations, allowing us to discriminate among ligands with similar affinities. QTAIM analysis gives fairly accurate information for weak interactions which are not well described by MD simulations. QTAIM study also allowed us to evaluate and determine which parts of the ligand need to be modified in order to increase its interactions with the molecular target. In this study we have discussed the importance of combined MD/QTAIM calculations for this type of simulations, showing their scopes and limitations.The complex etiology of Alzheimer's disease has initiated a quest for multi-target ligands to address the multifactorial causes of this neurodegenerative disorder. In this context, we designed dual-acting 5-HT6 receptor (5-HT6R) antagonists/MAO-B inhibitors using pharmacophore hybridization strategy. OSI-027 datasheet Our approach involved linking priviliged scaffolds of 5-HT6R with aryloxy fragments derived from reversible and irreversible MAO-B inhibitors. The study identified compound 48 that acts as an inverse agonist of 5-HT6R at Gs signaling and an irreversible MAO-B inhibitor. Compound 48 showed moderate metabolic stability in rat microsomal assay, artificial membrane permeability, no hepatotoxicity, and it was well distributed to the brain. Additionally, 48 showed glioprotective properties in a model of cultured astrocytes using 6-OHDA as the cytotoxic agent. Finally, compound 48 (MED = 1 mg/kg, p.o.) fully reversed memory deficits in the NOR task induced by scopolamine in rats. A better understanding of effects exerted by dual-acting 5-HT6R/MAO-B modulators may impact the future development of neurodegenerative-directed treatment strategies.Despite the emerging concerns about the hepatotoxic risks associated with Zinc oxide nanoparticles (ZnO NPs), yet, the morphological and molecular alterations associated with these extensively-used nanoparticles remain to be elucidated. Thus, the current study has been designed to analyze the effect of ZnO NPs on the hepatic histopathological and immunohistochemical changes, along with the modulation of the oxidative-stress induced JNK/p38MAPK and the STAT-3 signalling. The study also explored the potential protective role of selenium against those alterations. ZnO NPs disrupted the hepatic architecture, elevated the serum liver enzyme alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) levels and caused dose-dependent decrease in the activity of the antioxidant enzymes glutathione-peroxidase, superoxide dismutase and catalase along with an increase in the lipid peroxidation product malondialdehyde. ZnO NPs also increased the area of immune-reactivity of the apoptotic protein bax and decreased the area of immune-reactivity of the anti-apoptotic protein bcl2 together with augmentation of the hepatic caspase 3 gene expression. The role of selenium in ameliorating the hepatotoxicity, oxidative stress injury, and apoptosis induced by ZnO-NPs, along with its role in modulating the JNK/p38MAPK and the STAT-3 signalling and improving the histopathological hepatic changes, offers selenium as a promising adjunctive therapy in individuals subjected to high concentrations of ZnO NPs especially in cases of extensive occupational, medicinal and industrial exposure.

Direct thrombin inhibitor, dabigatran and factor Xa inhibitors, apixaban, edoxaban, and rivaroxaban (DOACs/NOACs), are currently the first-choice drugs in some indications. Life-threatening bleeding occurring during DOACs treatment may benefit from the use of reversal agents, however there are some concerns regarding potential rebound thrombotic events. In this systematic review we aimed to estimate the incidence of thrombotic events in patients treated with idarucizumab or andexanet alfa.

This systematic review included all prospective and retrospective studies, enrolling patients that received specific antidotes (idarucizumab, andexanet alfa and cirapantag) for anticoagulation reversal, published until October 2019 in CENTRAL, MEDLINE and PsycINFO. Studies in healthy individuals and those with less than 10 patients were excluded. The primary outcome was the incidence of thrombotic events and the secondary outcome was all-cause mortality. Studies screening and data extraction was performed in duplicate by reviewers.
