In vitro study on the immunomodulatory effects of differently functionalized silver nanoparticles on human peripheral bl...
Published in Journal of Biological Inorganic Chemistry
The interaction of silver nanoparticles (AgNPs) with the immune system has not yet been sufficiently elucidated even though they belong to the most investigated and exploited group of nanomaterials. This study aimed to evaluate immunomodulatory effect of four different AgNPs on human peripheral blood mononuclear cells (hPBMCs). Fresh hPBMCs were ex...
Electrocardiographic manifestations of COVID-19: Effect on cardiac activation and repolarization
...Published in EClinicalMedicine
Background Prolonged QT intervals are reported in patients with COVID-19. Additionally, virus particles in heart tissue and abnormal troponin levels have been reported. Consequently, we hypothesize that cardiac electrophysiologic abnormalities may be associated with COVID-19. Methods This is a retrospective study between March 15th, 2020 and May 30...
Creation of sinus rhythm and paced maps using a single acquisition step: the "one acquisition-two maps" technique-a feas...
...Published in Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing
Scars and abnormal electrograms may significantly differ according to the activation wavefront. We propose a new fast technique for reliable comparison between sinus rhythm and ventricular pacing using a single map acquisition and the Rhythmia™ 3D mapping system. A special programming of the external stimulator was assuring full stable regular pace...
Efficient Degradation of 2,4-Dichlorophenol on Activation of Peroxymonosulfate Mediated by MnO2.
Published in Bulletin of environmental contamination and toxicology
Sulfate radical based-advanced oxidation process has received increasing interest in the remediation of wastewater and contaminated soil. In this study, degradation of 2, 4-dichlorophenol (2, 4-DCP) was investigated over peroxymonosulfate (PMS) activation by MnO2, which was prepared by liquid-phase oxidation method. The prepared MnO2 was characteri...
Selenoproteins as regulators of T cell proliferation, differentiation, and metabolism.
Published in Seminars in cell & developmental biology
Selenium (Se) is an essential micronutrient that plays a key role in regulating the immune system. T cells are of particular interest due to their important role in promoting adaptive immunity against pathogens and cancer as well as regulating tolerance, all of which are influenced by dietary Se levels. The biological effects of Se are mainly exert...
Functional evidence of distinct electrophile-induced activation states of the ion channel TRPA1
Published in Biochemistry and Biophysics Reports
Transient Receptor Potential Ankyrin 1 (TRPA1) is a tetrameric, nonselective cation channel expressed on nociceptive sensory nerves whose activation elicits nocifensive responses (e.g. pain). TRPA1 is activated by electrophiles found in foods and pollution, or produced during inflammation and oxidative stress, via covalent modification of reactive ...
The elusive promise of universal social protection: the case of the Greek general minimum income (GMI)
Purpose-The need to alleviate poverty and achieve the United Nations (UN) 2030 Sustainable Development Goals (SDGs) through Universal Social Protection (USP) mechanisms is a high priority for governments and international organisations (IOs). This paper focuses on the recent introduction of a general minimum income (GMI) in Greece, in the context o...
Maintaining Plasmodium falciparum gametocyte infectivity during blood collection and transport for mosquito feeding assa...
...Published in Malaria Journal
BackgroundMosquito feeding assays using venous blood are commonly used for evaluating the transmission potential of malaria infected individuals. To improve the accuracy of these assays, care must be taken to prevent premature activation or inactivation of gametocytes before they are fed to mosquitoes. This can be challenging in the field where inf...
Activation of parasperm and eusperm upon ejaculation in Lepidoptera.
Published in Journal of insect physiology
Almost all Lepidoptera produce two kinds of spermatozoa, a typical nucleated spermatozoön and an anucleate one. Inactive in the male prior to ejaculation, both of these spermatozoa become motile upon ejaculation and move to the female's sperm storage organ. This study shows that in several phylogenetically and morphologically diverse species of Lep...
