PREVENTION OF TUBERCULOSIS AT SCHOOL AGE-AWARENESS OF SECONDARY SCHOOL STUDENTS
Aim: carrying out of secondary school students’ health awareness about tuberculosis’ characteristics and its prophylaxis.Materials and methods: An anonymous inquiry examination of 190 students at the age of 15-18, 69 (36%) of who - boys and 121 (64%) girls in IX, X, XI classes, from 3 secondary schools in Varna. The inquiry consists of 32 questions, classified in 4 sections. SPSS ver. 19.0 software package was used for statistical data processing.Results: Studies show that the interviewed students are aware of the basic characteristics of tuberculosis. The research displays significant differences between girls and boys` answers. Boys are better grounded in the causes, the processes of transmission and the basic prophylactic measures for prevention of tuberculosis whereas girls are very knowledgeable about the main symptoms of the disease
Real or Artificial? Intergroup Biases in Mind Perception in a Cross-Cultural Perspective
Recent research suggests that attributions of aliveness and mental capacities to faces are influenced by social group membership. In this article, we investigated group related biases in mind perception in participants from a Western and Eastern culture, employing faces of varying ethnic groups. In Experiment 1, Caucasian faces that ranged on a continuum from real to artificial were evaluated by participants in the UK (in-group) and in India (out-group) on animacy, abilities to plan and to feel pain, and having a mind. Human features were found to be assigned to a greater extent to faces when these belonged to in-group members, whereas out-group faces had to appear more realistic in order to be perceived as human. When participants in India evaluated South Asian (in-group) and Caucasian (out-group) faces in Experiment 2, the results closely mirrored those of the first experiment. For both studies, ratings of out-group faces were significantly predicted by participants’ levels of ethnocultural empathy. The findings highlight the role of intergroup processes (i.e., in-group favoritism, out-group dehumanization) in the perception of human and mental qualities and point to ethnocultural empathy as an important factor in responses to out-groups
The multi-modal nature of trustworthiness perception
Most past work on trustworthiness perception has focused on the structural features of the human face. The present study investigates the interplay of dynamic information from two channels – the face and the voice. By systematically varying the level of trustworthiness in each channel, 49 participants were presented with either facial or vocal information, or the combination of both, and made explicit judgements with respect to trustworthiness, dominance, and emotional valence. For most measures results revealed a primacy effect of facial over vocal cues. In examining the exact nature of the trustworthiness - emotion link we further found that emotional valence functioned as a significant mediator in impressions of trustworthiness. The findings extend previous correlational evidence and provide important knowledge of how trustworthiness in its dynamic and multi-modal form is decoded by the human perceiver. Index Terms: trustworthiness, face, voice, emotion, dynamic, multi-moda
OsEUL lectin gene expression in rice : stress regulation, subcellular localization and tissue specificity
The Euonymus lectin (EUL) family is a unique group of carbohydrate-binding proteins that is omnipresent in plants. Sequences encoding EUL-related lectins have been retrieved from all completely sequenced plant genomes. The rice (Oryza sativa) genome contains 5 functional EUL genes referred to as OsEULS2, OsEULS3, OsEULD1a, OsEULD1b, and OsEULD2. In this study we focused on the tissue specific expression, stress inducibility and subcellular localization of the rice EULs. Even though the EUL domain sequence is highly conserved among the rice EULs (at least 80% sequence similarity) different biotic and abiotic stress treatments yielded unique responses for the different EULs. Transcript levels for OsEULs were differentially affected by drought and salt stress, ABA treatment, pathogen infection or insect infestation. Analysis of promoter activity revealed differential expression and tissue specificity for the 5 OsEUL genes, with most expression observed in the vascular system of roots and shoots, as well as in the root tips and seeds. At cell level, all OsEULs are located in the nucleus whereas OsEULD1b and OsEULD2 also locate to the cytoplasm. This paper contributes to the functional characterization of the EULs and provides insight in the biological importance of this family of proteins for rice
Spatio-temporally separated cortical flows and spindle geometry establish physical asymmetry in fly neural stem cells
Asymmetric cell division, creating sibling cells with distinct developmental potentials, can be manifested in sibling cell size asymmetry. This form of physical asymmetry occurs in several metazoan cells, but the underlying mechanisms and function are incompletely understood. Here we use Drosophila neural stem cells to elucidate the mechanisms involved in physical asymmetry establishment. We show that Myosin relocalizes to the cleavage furrow via two distinct cortical Myosin flows: at anaphase onset, a polarity induced, basally directed Myosin flow clears Myosin from the apical cortex. Subsequently, mitotic spindle cues establish a Myosin gradient at the lateral neuroblast cortex, necessary to trigger an apically directed flow, removing Actomyosin from the basal cortex. On the basis of the data presented here, we propose that spatiotemporally controlled Myosin flows in conjunction with spindle positioning and spindle asymmetry are key determinants for correct cleavage furrow placement and cortical expansion, thereby establishing physical asymmetry
Comparative study of lectin domains in model species : new insights into evolutionary dynamics
Lectins are present throughout the plant kingdom and are reported to be involved in diverse biological processes. In this study, we provide a comparative analysis of the lectin families from model species in a phylogenetic framework. The analysis focuses on the different plant lectin domains identified in five representative core angiosperm genomes (Arabidopsisthaliana, Glycine max, Cucumis sativus, Oryza sativa ssp. japonica and Oryza sativa ssp. indica). The genomes were screened for genes encoding lectin domains using a combination of Basic Local Alignment Search Tool (BLAST), hidden Markov models, and InterProScan analysis. Additionally, phylogenetic relationships were investigated by constructing maximum likelihood phylogenetic trees. The results demonstrate that the majority of the lectin families are present in each of the species under study. Domain organization analysis showed that most identified proteins are multi-domain proteins, owing to the modular rearrangement of protein domains during evolution. Most of these multi-domain proteins are widespread, while others display a lineage-specific distribution. Furthermore, the phylogenetic analyses reveal that some lectin families evolved to be similar to the phylogeny of the plant species, while others share a closer evolutionary history based on the corresponding protein domain architecture. Our results yield insights into the evolutionary relationships and functional divergence of plant lectins
Vocal and facial trustworthiness of talking heads
Trust is a key aspect to human communication due to its link to co-operation and survival. Recent research by [Ballew and Todorov 2007] has shown that humans can generate an initial trustworthiness judgement based on facial features within 100ms. However, in that work, perceived trustworthiness has been studied solely in the context of facial information. It has been suggested by [Surawski and Ossoff 2006] that trustworthiness cues are also prevalent in the auditory channel. There is however, no prior empirical evidence to suggest that visual cues are more important than audio cues and how people deal with inconsistent cues between the audio and visual channels
COLLABORATION BETWEEN HILFSWERK AUSTRIA, A PRIVATE HUMANITARIAN ORGANIZATION, AND PAEDIATRIC ONCOHAEMATOLOGICAL CLINICS IN I SOFIA, PLOVDIV, AND VARNA
Non-governmental organizations (NGO) with humanitarian orientation from the European-Union countries are traditionally involved in joint projects in Asia, Africa, and Latin America. Political and socio-economic changes in Eastern Europe attract the humane interest of numerous NGO in the former socialist countries and in Bulgaria as well. The significant question of the optimal building-up a fruitful collaboration in the public health sphere between the present institutions in our country and NGO-donors from abroad has already been posed. In 1996, HILFSWERK Austria (Vienna) has concentrated 60 per cent of its financial means in order to help the new democratic reforms in Eastern Europe, the former Soviet Union, and Mongolia. The total amount of own and drawn-in financial means has been of US$ 50 mill. Of them, 31 per cent has been directed to projects designed to use in the social and public health spheres. In 1997-1998, the Bulgarian paediatric oncohaematological clinics in Sofia, Plovdiv, and Varna have successfully participated in a joint project with HILFSWERK Austria providing necessary drugs and sanitary materials. The current state, problems, and perspectives of the collaboration between this NGO and these clinics mediated through the "Dialogue" Institute of Social Sciences and Social Policy in Varna can characterize by a typical manner the interrelations between the public health institutions and foreign humanitarian NGO in Bulgaria
