Psychology and Management of the Workforce in Post-Stalinist Hungary
2019
Over recent years, there has been a growing academic interest in the history of psychological disciplines and mental health in the Soviet Union and eastern Europe. This article explores psychological sciences and social planning in post-Stalinist Hungary after 1956. The focus is on the psychology of work as a socially- and historically-situated discourse. The article demonstrates how psychologists started to promote their expertise to reform the practices of management and to “humanize” the conditions of work. They suggested practical remedies for everyday problems of worker motivation and social adjustment and introduced concepts from social psychology to improve the state of interpersonal…
Glimmering utopias: 50 years of African film
2010
The history of African film began in the 1960s with the independence of the colonies. Despite all kinds of political and economic difficulties, numerous films have been made since then, featuring wide-ranging processes of consolidation, differentiation and transformation which were characteristic of post-colonial sub-Saharan Africa. However, these feature films should not merely be viewed as back references to specifically African problems. The glimmering fictions are imagination spaces. They preserve ideas about how the post-colonial circumstances should be approached. Seen from this perspective, the history of African film may be studied as a history of African utopias. Die Geschichte des…
The Proteome and Lipidome of Synechocystis sp. PCC 6803 Cells Grown under Light-Activated Heterotrophic Conditions*
2015
Cyanobacteria are photoautotrophic prokaryotes with a plant-like photosynthetic machinery. Because of their short generation times, the ease of their genetic manipulation, and the limited size of their genome and proteome, cyanobacteria are popular model organisms for photosynthetic research. Although the principal mechanisms of photosynthesis are well-known, much less is known about the biogenesis of the thylakoid membrane, hosting the components of the photosynthetic, and respiratory electron transport chain in cyanobacteria. Here we present a detailed proteome analysis of the important model and host organism Synechocystis sp. PCC 6803 under light-activated heterotrophic growth condition…
Study of electrostatic potential surface distribution of wild-type plastocyaninSynechocystissolution structure determined by homonuclear NMR
2003
Plastocyanin is a small (∼10 kDa), type I blue copper protein that works as an electron donor to photosystem I from cytochrome f in both chloroplast systems and in some strains of cyanobacteria. Comparative studies of the kinetic mechanisms of plastocyanins in different organisms show that the electron transfer from photosystem I happens by simple collision in cyanobacteria but through a intermediate transition complex in green algae and superior plants. Previous work has proved that this effect cannot be explained by structural variations across the different plastocyanins but it can be explained by differences in the electrostatic potential distribution at the protein surface. In that cas…
Induction of primary NY-ESO-1 immunity: CD8+ T lymphocyte and antibody responses in peptide-vaccinated patients with NY-ESO-1+ cancers
2000
Cancer–testis antigen NY-ESO-1 is one of the most immunogenic tumor antigens defined to date. Spontaneous humoral and CD8+ T-cell responses to NY-ESO-1 are detected in 40–50% of patients with advanced NY-ESO-1-expressing tumors. A clinical trial was initiated to study the immunological effects of intradermal vaccination with 3 HLA-A2-binding NY-ESO-1 peptides in 12 patients with metastatic NY-ESO-1-expressing cancers. Seven patients were NY-ESO-1 serum antibody negative, and five patients were NY-ESO-1 serum antibody positive at the outset of the study. Primary peptide-specific CD8+ T-cell reactions and delayed-type hypersensitivity responses were generated in four of seven NY-ESO-1 antibod…
The occurrence of serological H-Y antigen (Sxs antigen) in the diandric protogynous wrasse, Coris julis (L.) (Labridae, Teleostei)
1987
Abstract The serological sex-specific (Sxs) antigen (previously called ‘H-Y antigen’) has been shown, in various vertebrate species ranging from fish to mammals, to be characteristic of the heterogametic sex. We studied a protogynous hermaphrodite, Coris julis , in order to examine whether the change of a female to a secondary male also involves a change in the Sxs-antigen phenotype. The (homogametic) females of this species were found to be Sxs negative, while both primary and secondary males were Sxs positive. This was true not only for gonads but also for nongo-nadal tissues. The administration of androgen to females is known to cause sex inversion in this species; we were able to demons…
Gestācijas dominantes psiholoģiskās komponentes hipogestognostiskā varianta izplatība un saistība ar atioforiognoziju dzemdību palīdzības iestādes pa…
2015
Ievads. Gestācijas dominantes psiholoģiskā komponente ir psihisko pašregulācijas mehānismu kopums grūtniecības saglabāšanai. Hipogestognostiskais variants raksturīgs sievietēm, kuras apzināti vai biežāk neapzināti nepieņem savu grūtniecību. Sakarā ar to, ka gestācijas dominantes psiholoģiskās komponentes hipogestognostiskais variants ir cieši saistīts ar grūtniecības noliegšanu, kas apdraud gan mātes, gan bērna dzīvību, nepieciešams pēc iespējas agrīni novērtēt grūtnieces psiholoģisko stāvokli. Pētījuma mērķis. Veicot prospektīvo pētījumu novērtēt grūtnieču gestācijas dominantes psiholoģiskās komponentes hipogestognostiskā varianta biežumu, kā arī noskaidrot grūtniecības nelabvēlīga iznākum…
Sex-specific windows for high mRNA expression of DNA methyltransferases 1 and 3A and methyl-CpG-binding domain proteins 2 and 4 in human fetal gonads
2006
DNA methyltransferases (DNMTs) and 5-methyl-CpG-binding domain proteins (MBDs) are involved in the acquisition of parent-specific epigenetic modifications in human male and female germ cells. Reverse Northern blot analyses demonstrated sex-specific differences in mRNA expression for the maintenance DNMT1 and the de novo DNMT3A in developing testis and ovary. In fetal testis DNMT1 and DNMT3A expression peaked in mitotically arrested spermatogonia around 21 weeks gestation. In fetal ovary transcriptional upregulation of DNMT1 and DNMT3A occurred during a very brief period at 16 weeks gestation, when the oocytes proceeded through meiotic prophase. Fetal gonads showed several fold higher DNMT3A…
Isolation of methanotrophic bacteria from termite gut.
2015
The guts of termites feature suitable conditions for methane oxidizing bacteria (MOB) with their permanent production of CH4 and constant supply of O2 via tracheae. In this study, we have isolated MOB from the gut contents of the termites Incisitermes marginipennis, Mastotermes darwiniensis, and Neotermes castaneus for the first time. The existence of MOB was indicated by detecting pmoA, the gene for the particulate methane monooxygenase, in the DNA of gut contents. Fluorescence in situ hybridization and quantitative real-time polymerase chain reaction supported those findings. The MOB cell titer was determined to be 10(2)-10(3) per gut. Analyses of the 16S rDNA from isolates indicated clos…
