Yksilö ja joukko nimeltä kulttuuri : Sigmund Freudin ja Erich Frommin ihmiskäsitykseen pohjautuva tarkastelu yksilön suhteesta yhteiskuntaan ja muihi…
2016
Tutkielmani tarkoituksena on tarkastella Sigmund Freudin ja Erich Frommin kuvaa ihmisluonnosta, ihmisestä sosiaalisena olentona sekä ihmisen suhteesta maailmaan. Käyn aluksi lävitse Freudin ihmiskuvaa, jossa ihmisen käytös on pitkälti ulkomaailman realiteettien sanelemaa, mutta ihminen omaa kyvyn sisäistää ulkomaailman osia itseensä, muovaten siten sekä itseään että suhdettaan maailmaan. Yritän työssäni tarkastella tämän todellisuussuhteen muovaamisen syitä, taustoja ja seuraamuksia. Käsittelen kulttuuria ja perhettä erikoisina joukkona, joihin ihminen joutuu välttämättä suhtautumaan, ja jotka väistämättä kohdistavat meihin reagointia vaativia realiteetteja. Painotan Freudkäsittelyssä rakka…
The genome sequence of Blochmannia floridanus: Comparative analysis of reduced genomes
2003
Bacterial symbioses are widespread among insects, probably being one of the key factors of their evolutionary success. We present the complete genome sequence of Blochmannia floridanus , the primary endosymbiont of carpenter ants. Although these ants feed on a complex diet, this symbiosis very likely has a nutritional basis: Blochmannia is able to supply nitrogen and sulfur compounds to the host while it takes advantage of the host metabolic machinery. Remarkably, these bacteria lack all known genes involved in replication initiation ( dna A, pri A, and rec A). The phylogenetic analysis of a set of conserved protein-coding genes shows that Bl. floridanus is phylogenetically related to Buch…
Cytotoxic necrotizing factor type 2 produced by virulent Escherichia coli modifies the small GTP-binding proteins Rho involved in assembly of actin s…
1994
Cytotoxic necrotizing factor type 2 (CNF2) produced by Escherichia coli strains isolated from intestinal and extraintestinal infections is a dermonecrotic toxin of 110 kDa. We cloned the CNF2 gene from a large plasmid carried by an Escherichia coli strain isolated from a lamb with septicemia. Hydropathy analysis of the deduced amino acid sequence revealed a largely hydrophilic protein with two potential hydrophobic transmembrane domains. The N-terminal half of CNF2 showed striking homology (27% identity and 80% conserved residues) to the N-terminal portion of Pasteurella multocida toxin. Methylamine protection experiments and immunofluorescence studies suggested that CNF2 enters the cytosol…
E. coli mikrobioloģiskais piesārņojums un riska novērtēšana maltā liellopu gaļā
2016
Escherichia coli ir zarnu traktā sastopama baktērija, kas ārpus tā var pieķerties virsmām, veidojot biofilmu, tādēļ jebkurā kaušanas – pārstrādes etapā var notikt gaļas kontaminācija. EK regula Nr. 2073/2005 norāda, ka E. coli izmanto kā fekālā piesārņojuma indikatoru, pielietojot analītisko metodi ISO 16649-2 β-glikuronidāzes pozitīvo E. coli skaita noteikšanai. Šajā darbā ir novērtēts E. coli piesārņojuma līmenis maltas liellopu gaļas produktos, novērtēta un salīdzināta skaita izmaiņa dabiskā un mākslīgā piesārņojumā, izmantojot izaicinājuma testu. Iegūtie rezultāti ir apmierinoši, jo E. coli skaits produktos, pēc EK regulas Nr. 2073/2005, nepārsniedz minimālo vērtību – 50 KVV/g. Izaicinā…
Przyczynek do marksistowskiej krytyki automobilizmu
2015
The aim of this paper is to analyze private automobilism in capitalist system from the Marxist perspective. Author starts with Paul Yirilio thought on speed and politics, issues of the mobility and social and political control. Then article is focused on Erich Fromm’s, thinker from the Frankfurt School, criticism o f private owned cars. Next part is devoted to the social and cultural significance o f the car-first transportation in the United States. Paper ends with alternative point of view on the automobilism, delivered by punk rock artist, known as Jello Biafra. In conclusion, there is an attempt to outline socialist option on motorization.
The dynamic concept of humor : Erich Fromm and the possibility of humane humor
2016
This dissertation focuses on the social philosophy of humor from the viewpoint of Erich Fromm’s critical humanistic thinking. The work consists of an introduction and four individual articles. The introduction discusses Fromm’s theories in relation to the phenomenon of humor to provide a basis for the articles. The central aim is to understand the dynamic nature of humor and how it is related to the problem of being a paradoxical creature, that is, a human being. It is claimed that humor has to be analyzed and interpreted in a unique historical and cultural situation. The first article discusses Fromm’s concept of social character to offer a theoretical tool to understand how deeply humor i…

Double copies of blaKPC-3::Tn4401a on an IncX3 plasmid in Klebsiella pneumoniae successful clone ST512 from Italy
2015
ABSTRACT A carbapenem-resistant sequence type 512 (ST512) Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing K. pneumoniae strain showing a novel variant plasmid content was isolated in Palermo, Italy, in 2014. ST512 is a worldwide successful clone associated with the spread of bla KPC genes located on the IncFIIk pKpQIL plasmid. In our ST512 strain, the bla KPC-3 gene was unusually located on an IncX3 plasmid, whose complete sequence was determined. Two copies of bla KPC-3 ::Tn 4401a caused by intramolecular transposition events were detected in the plasmid.
Regulation of type 1 fimbriae synthesis and biofilm formation by the transcriptional regulator LrhA of Escherichia coli
2005
Type 1 fimbriae ofEscherichia colifacilitate attachment to the host mucosa and promote biofilm formation on abiotic surfaces. The transcriptional regulator LrhA, which is known as a repressor of flagellar, motility and chemotaxis genes, regulates biofilm formation and expression of type 1 fimbriae. Whole-genome expression profiling revealed that inactivation oflrhAresults in an increased expression of structural components of type 1 fimbriae.In vitro, LrhA bound to the promoter regions of the twofimrecombinases (FimB and FimE) that catalyse the inversion of thefimApromoter, and to the invertible element itself. TranslationallacZfusions with these genes and quantification offimEtranscript le…
Properties of transmembrane helix TM1 of the DcuS sensor kinase of Escherichia coli, the stator for TM2 piston signaling
2021
Abstract The sensor kinase DcuS of Escherichia coli perceives extracellular fumarate by a periplasmic PASP sensor domain. Transmembrane (TM) helix TM2, present as TM2-TM2′ homo-dimer, transmits fumarate activation in a piston-slide across the membrane. The second TM helix of DcuS, TM1, is known to lack piston movement. Structural and functional properties of TM1 were analyzed. Oxidative Cys-crosslinking (CL) revealed homo-dimerization of TM1 over the complete membrane, but only the central part showed α-helical +3/+4 spacing of the CL maxima. The GALLEX bacterial two-hybrid system indicates TM1/TM1′ interaction, and the presence of a TM1-TM1′ homo-dimer is suggested. The peripheral TM1 regi…
