Figurální (neboli neverbální) fluence je schopnost exekutivních funkcí, která nám poskytuje informace o divergentním myšlení, rozdělené pozornosti, plánování a mentální flexibilitě. Zhoršený výkon v testech zaměřených na figurální fluenci nacházíme u pacientů s neurologickým i psychiatrickým postižením. Pětitečkový test (Five Point Test, 5TT) je jeden z neuropsychologických testů, jenž slouží ke zhodnocení figurální fluence. Úkolem probanda je vytvořit co nejvíce obrazců v časovém limitu. Cílem této studie bylo vytvořit normy k 5TT pro českou dospělou populaci. Předkládáme normativní data pro dospělé ve věku od 20 do 85 let (n = 503). Hodnotili jsme počet správných odpovědí a počet perseverací. Počet správných odpovědí je ovlivněn věkem a vzděláním (r = –0,3; resp. 0,4; p < 0,0001), proto jsou normy rozděleny na pásma po 10 letech a dále podle ukončeného vzdělání. Počet perseverací s těmito proměnnými souvisí jen slabě (rs = 0,1; resp. –0,1; p < 0,05). Pohlaví nemá vliv na počet správných odpovědí ani perseverací (t = 0,09; p > 0,9 pro oba skóry)., Figural (or nonverbal) fluency is the ability of executive functions to provide information about divergent reasoning, divided attention, planning and mental flexibility. Impairments of figural fluency have been found in individuals with various neurological or psychiatric diseases. Five Point Test (5TT) is a neuropsychological test that assesses figural fluency. A participant is asked to generate as many unique designs as possible in a certain time limit. The aim of this study was to create Czech population norms for the Five Point Test. Normative data for adult population aged between 20 and 85 years (n = 503) are presented. We assessed the number of correct answers and the number of perseverations. The number of correct answers is influenced by age and education (r = –0.3 and 0.4, respectively, p < 0.0001); for this reason the norms are stratified into ten age ranges and also according to completed education. The number of perseverations correlates with these variables only weakly (rs = 0.1 and –0.1, respectively, p < 0.05). Gender has no impact neither on the number of correct answers nor on perseverative responses (t-test, p > 0.9 for both scores). Key words: Five Point Test – design fluency – normative data – executive functions – validity The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE “uniform requirements” for biomedical papers., and S. Johanidesová, E. Bolceková, H. Štěpánková, M. Preiss
INTRODUCTION: The male:female ratio at birth (male births divided by total live births - M/T) has been shown to increase in response to ionizing radiation due to gender-biased fetal loss, with excess female loss. M/T rose sharply in 1987 in central-eastern European countries following the Chernobyl accident in 1986. This study analyses M/T and births for the former Soviet Republics and for the countries most contaminated by the event. METHODS: Annual birth data was obtained from the World Health Organisation. The countries with the highest exposure levels (by 137Cs) were identified from an official publication of the International Atomic Energy Agency. All of the former Soviet states were also analysed and the periods before and after 1986 were compared. RESULTS: Except for the Baltic States, all regions in the former USSR showed a significant rise in M/T from 1986. There were significant rises in M/T in the three most exposed (Belarus, Ukraine and the Russian Federation). The birth deficit in the post-Soviet states for the ten years following Chernobyl was estimated at 2,072,666, of which 1,087,924 are accounted by Belarus and Ukraine alone. DISCUSSION: Chernobyl has resulted in the loss of millions of births, a process that has involved female even more than male fetuses. This is another and oft neglected consequence of widespread population radiation contamination. and V. Grech
The condition of the protective barrier of the stomach in patients with duodenal ulcer associated and non-associated with H. pylori infection has been studied. The state of gastric mucosal barrier was studied in 72 patients with peptic ulcer disease association with H. pylori and 26 patients without H. pylori by determining the content of insoluble glycoproteins and its fractions in the basal portion of the gastric juice. In a comparative perspective the state of these indicators were studied depending on the association with H. pylori and the severity of the disease. In patients with H. pylori, damages of protective mucus barrier are characterized by the significant shortage of fucose, which is considered to be the main component of the insoluble glycoproteins. In patients without H. pylori, status of mucosal barrier is characterized by uniform and less significant reduction in the content of fractions of insoluble glycoproteins. In this patients the reduction of insoluble glycoproteins is not dependent on the frequency of exacerbation. The content of fucose in the mucous gel of gastric juice is a diagnostic criterion for determining the frequency of recurrence of the disease in patients with H. pylori infection., Abdujalol Vahabovich Yakubov, Nargiza Ihsanovna Pulatova, and Literatura
In this article, the results of the morphological study of the cerebral arteries in the patients with the hemorrhagic ischemic stroke on the background of metabolic syndrome were submitted. We established that under hemorrhagic stroke on the background of metabolic syndrome one could observe the atherosclerotic damages in the form of plaques, hyalinosis of vessels walls, destructive and necrotic changes of the middle coat of vessel wall, which are, in our opinion, the main reason in morphogenesis of hemorrhagic stroke. The atherosclerotic affection of the cerebral vessels with the lipidosis and fibrotic plaques in the vessel wall, which caused in disorganization of the vessel wall in the form intimae proliferation, structural reconstruction of the internal elastic membrane which resulted in narrowing of the vessel lumen and development of ischemia is the morphological basis for the ischemic stroke with the metabolic syndrome. Also diabetic microangiopathy with the development of the hyalinosis, vessels walls sclerosis, which provoked the microcirculatory and metabolism processes injury in the cerebral substance that complicate the disease course is the important factor of cerebral blood circulation damage., Natalia Chuiko, and Literatura
Aims: This is the first study carried out to describe the role of fetal microchimerism (FM) in the pathogenesis of uterine cancer. The prevalence and concentration of male fetal microchimeric cells (FMCs) were examined in endometrial tissues in relation to subtypes of uterine cancer, and the histological grade and stage of the tumor. FM occurrence was analyzed in relation to risk factors including hypertension, obesity, type 2 diabetes, dyslipidemia, age at cancer diagnosis and patient pregnancy history. The prevalence and concentration of FMCs were examined in endometrial tissues using real-time polymerase chain reaction, SRY and b-globin sequences as markers for male fetal FMCs and total DNA. The studied group involved 47 type 1 endometrial cancers, 28 type 2 endometrial cancers and 41 benign uterine diseases. Results: While the prevalence of FM was decreased only in type 1 endometrial cancer, compared to benign uterine disorders (38.3% vs.70.7%; OR = 0.257, 95% CI: 0.105 to 0.628, p = 0.003), FMC concentrations did not differ within examined groups. The lower FM prevalence was detected in low grade (grade 1 and grade 2) endometrioid cancer (38.3% vs. 70.7%, OR = 0.256, 95% CI: 0.105 to 0.627, p = 0.003) and in FIGO 1 tumors (40.7% vs. 70.7%, OR= 0.285, 95% CI: 0.120 to 0.675, p = 0.004). No correlation between FM prevalence or FMC concentrations and risk factors was demonstrated. Conclusions: A lower prevalence of male FM seemed to be associated with better prognoses in uterine cancer based on tumor subtype, histological grade and stage of the tumor. and Ilona Hromadnikova, Katerina Kotlabova, Petra Pirkova, Pavla Libalova, Zdenka Vernerova, Bohuslav Svoboda, Eduard Kucera
The Purpose of this study is to demonstrate the effectiveness of combined treatment for III AB stage of nonsmallcell lung cancer. Nonsmallcell lung cancer spread form treatment is disputable. Operation is not final solution. The combined treatment is being tested (in clinical trials) in this study. This article argues that a combination of treatment is a better option than that of a specific treatment. However, there is a need to find new effective options for combined treatment., Akhat Bukenov, Elena Gizbrekht, Ergaly Shauenov, Bekzhan Orazbayev, Kalmurat Razzakov, and Literatura
Objective: to analyze main clinical-statistical indices of spine and spinal cord injuries (SCI) and system of organization of medical aid to the victims. We conducted a cohort retrospective study of materials of medical institutions of Tashkent city. Medical records of patients and records of forensic examinations were analyzed. 242 cases of spinal cord injuries were studied. Over the last 10 years in Tashkent the frequency of SCI have been tend to increase, males and working-age people are dominated. In 60.9% of cases the injury was associated, in 36.2% - isolated, and in 2.9% - combined. Fallings from height and road traffic accidents were the main reasons for getting SCI. Lesions at cervical level registered in 45% of cases, thoracic level - 27.3%, at lumbar level - 27.7%, respectively. According to ASIA/IMSOP, full injuries were noted in 40.1% of cases, incomplete injures were in 59.9%. Overall mortality from SCI was 68.6%. study allowed to get in detail the clinical and statistical indicators of SCI in the region., Rukhulla Zabikhullaevich Khikmatullaev, Alisher Iskandarovich Iskandarov, Dildora Zabikhullaevna Khakimova, and Literatura
Cíl studie: Cílem studie bylo zjištění vztahů mezi manifestací tinnitu, nálezem na sluchových evokovaných potenciálech a genetickým pozadím u receptoru pro gamaaminomáselnou kyselinu typu A (GABA(A) receptor), podporující desinhibiční hypotézu vzniku tinnitu. Soubor a metodika: Bylo vyšetřeno 131 pacientů z hlediska sluchové ztráty, provedena kvantifikace tinnitu, sluchové evokované potenciály střední latence (MLR) a kmenové sluchové evokované potenciály (BAEP) a dále stanovení genotypu (CA)n repetitivní sekvence pro beta‑3 podjednotku GABA(A) receptoru. Následně byly hledány vztahy mezi jednotlivými výsledky a manifestací tinnitu. Výsledky: Byla nalezena korelace tinnitus skóre s amplitudovým poměrem vln V/III v BAEP (R = 0,22, p < 0,001) a s průměrným sluchovým prahem (R = 0,22, p = 0,17). Rovněž byla nalezena korelace tinnitus skóre s amplitudou vlny PA v MLR (R = 0,31–0,37; p < 0,001). Výsledky MLR neukázaly žádný vztah k průměrnému sluchovému prahu. U skupiny s kratší anamnézou tinnitu (méně než devět měsíců) byl prokázán rozdíl v manifestaci tinnitu na genotypu pro (CA)n repetitivní sekvenci genu pro beta‑3 podjednotku GABA(A) receptoru (p = 0,002). Tento výsledek byl rovněž konzistentní s rozložením amplitudy vlny PA v dané subpopulaci. Závěr: Tyto výsledky svědčí o existenci dvou hlavních regulačních mechanizmů vzniku tinnitu: první, který je závislý na velikosti sluchové ztráty, je na úrovni mozkového kmene, zatímco druhý je na úrovni korové s možnou souvislostí s genotypem (CA)n repetitivní sekvence pro beta‑3 podjednotku GABA(A) receptoru., Study aim:Study objective was to explore associations between manifestation of tinnitus, auditory evoked potentials and genetic background of gamma‑aminobutyric acid type A (GABA(A) receptors) to support the disinhibited feedback hypothesis of tinnitus generation. Materials and methods: A population of 131 patients was assessed for severity of hearing loss, quantification of tinnitus, mid‑latency responses (MLR) and brainstem auditory evoked potentials (BAEP), and (CA)n tandem repeat polymorphism in GABA(A) Beta‑3 subunit gene to establish any correlation with manifestation of tinnitus. Results: It was observed that tinnitus score correlates with V/III amplitude ratio in BAEP (R = 0.22, p < 0.001) and with mean pure tone audiometry (PTA) threshold (R = 0.22, p = 0.017). Analysis of the MLR results showed a significant correlation between the PA wave amplitude and the tinnitus score (R = 0.31–0.37; p < 0.001). MLR result analysis showed no statistically significant correlation between the wave amplitudes and the mean auditory threshold. An analysis of a subgroup with shorter clinical history (less than nine months) revealed a statistically significant difference in the tinnitus score in relation to the genotype of (CA)n tandem repeat of the GABRß3 receptor subunit gene (p = 0.002). This result was also consistent with the distribution of the PA wave amplitude in the given subpopulation. Conclusion: Our findings indicate existence of two main regulatory mechanisms of tinnitus generation: first, the brainstem mechanism is dependent on the severity of the hearing loss; second, the cortical mechanism is likely to be dependent on the genotype of (CA)n tandem repeat in GABA(A) beta‑3 subunit gene., and J.

We aimed to investigate in detail the structural mutations after influence of actellic insecticide at different doses and different temperature conditions. We tested effects of single introduction of different doses of actellic: 48, 96, 192, and 384 mg/kg. Cytogenetic effect of actellic in bone marrow cells at different temperature regimens was studied. Following actellic administration, animals were being in two temperature regimes: normal (18-20°C) and high (37-38°C). After treatment with actellic, animals were kept within 1, 2, 4 and 8 hours at high temperature (37-38°C), i.e. in a thermostat (TV-80) with access of air. In experiments, the animals were divided into seven groups. The animals of the 1st group were administered actellic at a dose 384 mg/kg and kept under normal temperature until slaughtering. The animals of the 2nd group after administration of actellic were immediately placed in an environment with a temperature of 37-38°C. Animals of the 3rd, 4th, 5th, and 6th groups after treatment with actellic were transferred to conditions with high temperature, respectively, for 1, 2, 4 and 8 hours. The 7th group of mice was under normal temperature conditions without treatment with actellic. Our results have shown that in normal temperature conditions single exposure of actellic (384 mg/kg) did not affect the genetic apparatus of somatic cell, evidenced by the frequency of chromosome aberrations in bone marrow cells that were within the control levels. However, at high temperatures (37-38°C) the pesticide caused 6-fold larger number of chromosome aberrations in bone marrow cells, in comparison with normal conditions., Anvarjon Rakhmankulovich Shermuratov, and Literatura
