Abstract: The main purpose of this study was to examine the phonological skills among children with reading disabilities of the Bosnian/Croatian/Serbian language, where each phoneme is represented by a grapheme following a certain phonemic principle. The sample consists of 15 children with reading disabilities and 15 children without reading disabilities, where "The diagnostic set for examination of the speech, language, reading and writing abilities among children" was used for examination of their phonological capacity. Phonological skills in children are very important for reading and writing acquisition. The results of the study showed that children with reading disabilities achieved poorer results in all tasks examining the phonological skills, compared to children without reading difficulties. The results of our study comply with results of studies conducted for other languages. The study highlights the importance of the mentioned skills for acquiring reading skills in the Bosnian Croatian/Serbian language and the significance of deficient phonological abilities for the etiology of reading disabilities. Based on the conducted study, it can be concluded that phonological skills are very important for acquiring reading and writing abilities.

Abstract: Introduction: The purpose of this research was to establish voice acoustic characteristics in stuttering children with mild and severe stuttering and relationship between degree of stuttering and characteristics of voice in children. Methods: Sample consisted of two subsamples of male subjects (subsample of subjects with mild stuttering and subsample of subjects with severe stuttering) aged 7 to 10,5. Control group of subjects consisted of 46 fluent speakers, matched by age and sex with experimenal group. This research was conducted in twenty primary schools in Tuzla Canton among children attending grades 1 to 4. Results: Results of this research showed that subjects with severe stuttering had more expressed short frequency variations and variations of amplitude in the vocal tone. Factor analysis revealed four significant factors: factor of frequency variation, phonation factor, factor of aerodynamic phonation characteristics and intensity variation factor. Results of one-way factor analysis of variance between examined groups in factors of voice acoustic characteristics showed that factor 4 contributed the most to differentiation of groups. This factor was created from variables describing variation of amplitude in the vocal tone. Examination of correlation between four factors revealed statistically significant correlation between factor of frequency variation and intensity variation factor. Results of canonic analysis showed that variables of stuttering intesity correlated significantly with variable intensity variation. Results of this study also showed that acoustic analysis of voice in stuttering children might be useful for indepth analyses of stuttering manifestations. Conclusions: Results of this study might serve as incentive for furthter studies of different aspects of acoustic and physiologic phonation characteristics in stuttering children.

Acta Medica Saliniana , 2009, DOI: 10.5457/ams.51.09
Abstract: Aim: To determine the frequency of delirium in patients with acute stroke. Patients and methods: We assessed delirium prospectively in a sample of 233 consecutive patients with an acute (≤ 4 days) stroke using the Delirium Rating Scale R-98 and the Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition criteria for delirium. Results: Delirium was diagnosed in 59 (25.3%) patients. Patients with delirium were older comparing to those without delirium (70.0±11.3 vs. 64.7±10.4 years of age; p=0.001). Delirium was significantly more frequent in hemorrhagic comparing to the ischemic type of stroke (41.6% vs. 22.3%, p=0.02). In patients with the ischemic stroke, the delirium was more frequent among those with right hemispheric lesion (26.2% vs. 20.5%, p=0.0006); however, in hemorrhagic stroke delirium was more frequent in patients with left hemispheric lesion (42.9% vs. 27.8%, p=0.002). Delirium was also more frequent in patients with ischemic stroke in the anterior than posterior cerebral circulation territory (22.7% vs. 5.6%, p=0.0001). Conclusion: Delirium develops in approximately one quarter of patients in the acute phase of stroke. Possible factors which predispose the occurrence of delirium are ages over 65 years, hemorrhagic stroke, ischemic stroke in anterior cerebral circulation, lesion of right hemisphere in ischemic stroke and left hemisphere in hemorrhagic stroke.

Acta Medica Saliniana , 2009, DOI: 10.5457/ams.30.09
Abstract: Aim: To analyze anxiety in patients within 48 hours and 15th day after the ischemic stroke (IS) in relation to gender and location of the lesion. Patients and Methods: We analyzed 40 patients (mean age 65.3±10.3 years) with gender ratio 20:20. Mean age of hospitalized women was 66.35±7.31 years and men 64.2±12.68 years (p=0.5). IS was verified by computerized tomography (CT) of the brain in all patients. Anxiety level was measured with self estimated Zung scale. Score 50 and higher was verification of anxiety. Criteria made by Domasio were used to determine location of the IS. Results: Mean value on anxiety within 48 hours was 44.4 ± 8.8 and 42.2 ± 7.7 15th day after the IS (p=0.237). In 12 (30%) patients anxiety was found during the first and in 10 (25%) during the second evaluation. Women had higher level of anxiety with significant gender differences within first 48 hours (47.75 ± 8.4 : 41.05 ± 7.9) (p=0.013). In 9 (45%) female patients and 3 (15%) male patients anxiety was present within 48 hours from disease onset (p=0.024). Mean level of anxiety 15th day after the stroke in women was 45.7 ± 8.34 what was significantly different to 38.7 ± 5.24 in men (p=0.0029). In 9 (45%) women and 1 (5%) men mild to moderate anxiety was present (p=0.015). Concerning the circulation (anterior/posterior) and side of lesion (right/left hemisphere) there were no significant differences in level of anxiety in patients with IS (p=0.583; p=0.678 and p=0.207; p=0.27, respectively) neither within 48 hours nor 15th day after the disease onset. Conclusion: Gender has significant influence on anxiety rising within 48 hours and 15th day after the ischemic stroke (IS). Women have higher level of anxiety at both periods of measurements. Number of anxious patients is somewhat higher within 48 hours after the stroke but it is not significantly lower 15th day after the IS as well. Location of IS has no significant influence on anxiety after IS.
Serbo-Croat Clitics and Word Grammar

Research in Language , 2007, DOI: 10.2478/v10015-007-0001-7
Abstract: Serbo-Croat has a complex system of clitics which raise interesting problems for any theory of the interface between syntax and morphology. After summarising the data we review previous analyses (mostly within the generative tradition), all of which are unsatisfactory in various ways. We then explain how Word Grammar handles clitics: as words whose form is an affix rather than the usual ‘word-form’. Like other affixes, clitics need a word to accommodate them, but in the case of clitics this is a special kind of word called a ‘hostword’. We present a detailed analysis of Serbo-Croat clitics within this theory, introducing a new distinction between two cases: where the clitics are attached to the verb or auxiliary, and where they are attached to some dependent of the verb.

Abstract: In this paper we find exact formulas for the numbers of partitions and compositions of an element into $m$ parts over a finite field, i.e. we find the number of nonzero solutions of the equation $x_1+x_2+...+x_m=z$ over a finite field when the order does not matter and when it does, respectively. We also give an application of our results in the study of polynomials of prescribed ranges over finite fields.
Pathogen Proteins Eliciting Antibodies Do Not Share Epitopes with Host Proteins: A Bioinformatics Approach
Isaac Amela, Juan Cedano, Enrique Querol
PLOS ONE , 2007, DOI: 10.1371/journal.pone.0000512
Abstract: The best way to prevent diseases caused by pathogens is by the use of vaccines. The advent of genomics enables genome-wide searches of new vaccine candidates, called reverse vaccinology. The most common strategy to apply reverse vaccinology is by designing subunit recombinant vaccines, which usually generate an humoral immune response due to B-cell epitopes in proteins. A major problem for this strategy is the identification of protective immunogenic proteins from the surfome of the pathogen. Epitope mimicry may lead to auto-immune phenomena related to several human diseases. A sequence-based computational analysis has been carried out applying the BLASTP algorithm. Therefore, two huge databases have been created, one with the most complete and current linear B-cell epitopes, and the other one with the surface-protein sequences of the main human respiratory bacterial pathogens. We found that none of the 7353 linear B-cell epitopes analysed shares any sequence identity region with human proteins capable of generating antibodies, and that only 1% of the 2175 exposed proteins analysed contain a stretch of shared sequence with the human proteome. These findings suggest the existence of a mechanism to avoid autoimmunity. We also propose a strategy for corroborating or warning about the viability of a protein linear B-cell epitope as a putative vaccine candidate in a reverse vaccinology study; so, epitopes without any sequence identity with human proteins should be very good vaccine candidates, and the other way around.
