    E-hepatiidi viirus avastati 1983. aastal. Kuni viimase ajani oldi arvamusel, et E-hepatiit on vaid endeemilistes piirkondades esinev haigus ja sellesse haigestutakse neid piirkondi külastades. Nüüdseks on kirjanduses rohkesti andmeid, et E-hepatiit võib esineda Euroopas ka omamaise haigusena. Kirjeldatud on 48aastase meespatsiendi haigusjuhtu, kes haigestus ägedasse hepatiiti ja kel leiti veres E-hepatiidivastased antikehad. Haiguse kulg oli soodus, haige paranes.Eesti Arst 2013; 92(10):587–58

    RNA polymerase III contains seventeen subunits in yeasts (Saccharomyces cerevisiae and Schizosaccharomyces pombe) and in human cells. Twelve of them are akin to the core RNA polymerase I or II. The five other are RNA polymerase III-specific and form the functionally distinct groups Rpc31-Rpc34-Rpc82 and Rpc37-Rpc53. Currently sequenced eukaryotic genomes revealed significant homology to these seventeen subunits in Fungi, Animals, Plants and Amoebozoans. Except for subunit Rpc31, this also extended to the much more distantly related genomes of Alveolates and Excavates, indicating that the complex subunit organization of RNA polymerase III emerged at a very early stage of eukaryotic evolution. The Sch.pombe subunits were expressed in S.cerevisiae null mutants and tested for growth. Ten core subunits showed heterospecific complementation, but the two largest catalytic subunits (Rpc1 and Rpc2) and all five RNA polymerase III-specific subunits (Rpc82, Rpc53, Rpc37, Rpc34 and Rpc31) were non-functional. Three highly conserved RNA polymerase III-specific domains were found in the twelve-subunit core structure. They correspond to the Rpc17-Rpc25 dimer, involved in transcription initiation, to an N-terminal domain of the largest subunit Rpc1 important to anchor Rpc31, Rpc34 and Rpc82, and to a C-terminal domain of Rpc1 that presumably holds Rpc37, Rpc53 and their Rpc11 partner

    Since their discovery, liposomes have been widely employed in biomedical research. These nano-size spherical vesicles consisting one or few phospholipid bilayers surrounding an aqueous core are capable of carrying a wide variety of bioactive compounds, including drugs, peptides, nucleic acids, proteins and others. Despite considerable success achieved in synthesis of liposome constructs containing bioactive compounds, preparation of ligand-targeted liposomes comprising large quantities of encapsulated proteins that are capable of affecting pathological cells still remains a big challenge. Here we described a novel method for preparation of small (80\u201390 nm in diameter) unilamellar liposomes containing very large quantities (thousands of protein molecules per liposome) of heme-containing cytochrome c, highly fluorescent mCherry and highly toxic PE40 (Pseudomonas aeruginosa Exotoxin A domain). Efficient encapsulation of the proteins was achieved through electrostatic interaction between positively charged proteins (at pH lower than pI) and negatively charged liposome membrane. The proteoliposomes containing large quantities of mCherry or PE40 and functionalized with designed ankyrin repeat protein (DARPin)_9-29, which targets human epidermal growth factor receptor 2 (HER2) were shown to specifically stain and kill in sub-nanomolar concentrations HER2-positive cells, overexpressing HER2, respectively. Specific staining and eradication of the receptor-positive cells demonstrated here makes the DARPin-functionalized liposomes carrying large quantities of fluorescent and/or toxic proteins a promising candidate for tumor detection and therapy

    The features of a number of components of the cognitive processes of female students are considered, taking into account the lateral organization of the main analyzer systems and fluctuations in the functional state associated with changes in the hormonal background during the ovarian-menstrual cycle. It was found that the indicators of a number of components of cognitive processes differ in female students with different signs of functional asymmetry in the motor manual system and the fluctuations of these indicators during the ovarian-menstrual cycle — with differences in the lateral organization of not only the manual, but also the visual sphere.Рассмотрены особенности ряда компонентов познавательных процессов девушек-студенток при учете латеральной организации основных анализаторных систем и колебаний функционального состояния, связанных с изменением гормонального фона в течение овариально-менструального цикла. Обнаружено, что ряд показателей различается у студенток с разными признаками функциональной асимметрии в моторной мануальной системе, а колебания указанных показателей в течение овариально-менструального цикла — при различиях латеральной организации не только мануальной, но и зрительной сферы.Часть работы выполнена при поддержке РФФИ (грант № 18-013-01171/20)

    Genetics of aging and longevity

    Lifespan is a complex quantitative characteristic that makes a significant contribution to the Darwinian adaptiveness. The disclosure of the genetic structure of longevity is a fundamental problem of the evolution of ontogeny, evolutionary genetics and molecular gerontology. Under optimal conditions, the lifespan is determined by the aging rate. The aging process is made up of interrelated processes that take place at the organismal, tissue, cellular, molecular and genetic levels. These include deregulation processes of homeostasis maintenance, metabolic reactions and sending intra- and intercellular signals, accumulation of senescent cells, damaged organelles and macromolecules, epigenetic changes and genetic instability. The objective of this review is to summarize the available information about underlying genetic determinants of longevity and aging. Genes and signaling pathways that regulate stress response, metabolism, growth of cells and organism, maintaining of genome and proteome integrity, qualitative and quantitative mitochondria composition, inflammatory response, apoptosis and selection of viable cells, as well as circadian rhythms were considered. The redistribution of energy resources from one pathway to the other can induce or inhibit the ”longevity program”, providing increased vitality and aging slowdown. Based on the analysis of geroprotective potential of examined genes’ regulation, main targets have been identified to slowdown aging and achieve healthy longevity. These trends include heterochromatin recovery, retrotransposition suppression, aneuploidy elimination; restoring the acidity of lysosomes; telomere elongation; suppression of chronic inflammation; elimination of protein cross-links; elimination of senescent cells; recovery of NAD+ levels; inhibition of mTOR, S6K, TGF-β, AT1; controlled activation of the ”longevity program” genes FOXO, AMPK, PGC1α, NRF2

    The Neuronal Overexpression of Gclc in Drosophila melanogaster Induces Life Extension With Longevity-Associated Transcriptomic Changes in the Thorax

    Some effects of aging in animals are tissue-specific. In D. melanogaster neuronal overexpression of Gclc increases lifespan and improves certain physiological parameters associated with health benefits such as locomotor activity, circadian rhythmicity, and stress resistance. Our previous transcriptomic analyses of Drosophila heads, primarily composed of neuronal tissue, revealed significant changes in expression levels of genes involved in aging-related signaling pathways (Jak-STAT, MAPK, FOXO, Notch, mTOR, TGF-beta), translation, protein processing in endoplasmic reticulum, proteasomal degradation, glycolysis, oxidative phosphorylation, apoptosis, regulation of circadian rhythms, differentiation of neurons, synaptic plasticity, and transmission. Considering that various tissues age differently and age-related gene expression changes are tissue-specific, we investigated the effects of neuronal Gclc overexpression on gene expression levels in the imago thorax, which is primarily composed of muscles. A total of 58 genes were found to be differentially expressed between thoraces of control and Gclc overexpressing flies. The Gclc level demonstrated associations with expression of genes involved in the circadian rhythmicity, the genes in categories related to the muscle system process and the downregulation of genes involved in proteolysis. Most of the functional categories altered by Gclc overexpression related to metabolism including Drug metabolism, Metabolism of xenobiotics by cytochrome P450, Glutathione metabolism, Starch and sucrose metabolism, Citrate cycle (TCA cycle), One carbon pool by folate. Thus, the transcriptomic changes caused by neuron-specific Gclc overexpression in the thorax were less pronounced than in the head and affected pathways also differed from previous results. Although these pathways don't belong to the canonical longevity pathways, we suggest that they could participate in the delay of aging of Gclc overexpressing flies

    KIVUNHOIDON RISKIT JA HAASTEET GERONTOLOGISESSA HOITOTYÖSSÄ PÄIVYSTYKSESSÄ

    No full text
    Ikääntyneiden ihmisten kivun arvioiminen on usein vaikea sen takia, että gerontologisen hoitotyön riskejä ja haasteita on hyvin vähän tutkittu. Vanhemman väestön ikääntyessä, on tärkeä pitää ikääntyneiden potilaiden kivunhoitotyön osaamista ajan tasalla, sekä kehittää ja tutkia aihetta. Opinnäytetyön tarkoituksena oli selvittää ikääntyneiden päivystyspotilainen kivun hoitoon liittyviä riskejä ja haasteita. Opinnäytetyön tavoitteena oli ikääntyneiden kivun hoidon ja hoitomenetelmien kehittäminen osana moniammatillista työryhmää. Toimeksiantaja oli Kuopion yliopistollisen sairaalan (KYS) Palvelukeskus Akuutti ja sen kivunhoidon kehittämisryhmä. Opinnäytetyö toteutettiin laadullisena tutkimuksena teemahaastatteluna. Opinnäytetyön haastatteluihin osallistuivat päivystysyksikön eri alojen henkilökuntaa (N=6). Teemahaastattelujen aiheet olivat ikääntyneiden potilaiden kivun arviointiin ja hoitoon liittyvät haasteet ja riskit. Aineisto perustui Kuopion yliopistosairaalan henkilökunnan omiin kokemuksiin ja näkemyksiin. Haastattelut toteutettiin yksilöhaastatteluina. Haastattelujen perusteella saatiin tietoa yleisimmistä riskeistä ja haasteista, jotka vaikuttavat kivun arvioimiseen ja hoitoon. Opinnäytetyön tuloksena on saatu kokonaisvaltainen näkemys kivunhoidon riskeistä ja haasteista. Tutkimustulosten mukaan sairaanhoitajat kokivat, että gerontologiseen kivunhoitoon liittyy seuraavat riskit, kuten kommunikaatiovaikeudet aistivaikeuksien ja muistisairauksien vuoksi, päivystyspoliklinikan työkiireet, sekä kivun voimakkuuden oikea arviointi. Kipumittareiden avulla saadut tulokset eivät välttämättä vastaa potilaan tilannetta, joten kipumittareiden soveltuvuutta on pohdittu myös riskinä. Haastateltavan päivystysyksikkön henkilökunnan mielestä päivystyspoliklinnikan kivun hoito on asianmukaista, mutta isoimmat haasteet ovat kipulääkkeiden määräys, lääkkeiden yhteensopivuus ja potilaan oman lääkityksen käyttö. Resurssien puute, kiire ja henkilökunnan kokemus kivunhoidossa vaikuttavat hoidon tasoon. Tutkimusta voidaan hyödyntää hoitotyön koulutusta kehitettäessä ja erilaisia jatkokoulutuksia suunniteltaessa
