Let F be a finite field of characteristic p and K a field which contains a primitive pth root of unity and char K ≠ p. Suppose that a classical group G acts on the F-vector space V. Then it can induce the actions on the vector space \left [ V\bigoplus V \right ] and on the group algebra K\left [ V\bigoplus V \right ], respectively. In this paper we determine the structure of G-invariant ideals of the group algebra K\left [ V\bigoplus V \right ], and establish the relationship between the invariant ideals of K[V] and the vector invariant ideals of K\left [ V\bigoplus V \right ], and establish the relationship between the invariant ideals of K[V] and the vector invariant ideals of K\left [ V\bigoplus V \right ], if G is a unitary group or orthogonal group. Combining the results obtained by Nan and Zeng (2013), we solve the problem of vector invariant ideals for all classical groups over finite fields., Lingli Zeng, Jizhu Nan., and Obsahuje seznam literatury
Diabetes mellitus 2. typu představuje závažný medicínský, společenský i ekonomický problém, neboť se stal v posledních letech pandemickým onemocněním, postihuje ve stáří až třetinu české populace. Jde o klinicky nejvýznamnější metabolické onemocnění vyššího věku. Farmakoterapeutický přístup je třeba u seniorů přizpůsobit přítomnosti četných komorbidit, schopnosti pacienta spolupracovat na léčbě. Vzhledem k obávané hypoglykemii, která může přispívat ke zvýšené morbiditě, snižuje kvalitu života a limituje v mnoha případě možnosti léčby. Při rozhodování o léčbě je třeba vycházet z doporučení, která dělí diabetiky z geriatrického hlediska na seniory zdatné nebo křehké. Od toho se odvozují cílové hodnoty kompenzace diabetu. Cílem článku je popsat možnosti bezpečné léčby diabetes mellitus 2. typu u seniorů a upozornit na rizika, která může některá léčba seniorům přinášet., Type 2 diabetes mellitus represents a serious medical, social and economic problem, since it has become a pandemic in recent years, affecting up to 1/3 of the Czech population in old age. It is the clinically most significant metabolic disease in older age. A pharmacotherapeutic approach needs to be adjusted to the presence of multiple comorbidities in the elderly and to the patient’s ability to cooperate with treatment, and owing to the feared hypoglycemia which may contribute to increased morbidity, it detracts from the quality of life and limits the possibilities of treatment in many cases. When taking decisions about the treatment, the recommendations categorizing diabetic patients from the geriatric perspective as fit or fragile should be taken into account. The target values of diabetes compensation are derived from them. The purpose of the paper is to describe the possibilities of safe therapy for type 2 diabetes mellitus in older patients and draw attention to the risks that some types of treatment may present for older people., and Jiří Hradec, Eva Račická
Moderní účinná hypolipidemická farmakoterapie obvykle překrývá negativní vliv některých skupin farmak na lipidy. Přesto by určitý negativní účinek některých psychofarmak, antiepileptik, antihypertenziv či hormonální terapie měl být brán v úvahu. V přehledu uvádíme přehled některých lékových skupin vyvolávajících dyslipidemii i přehled farmak, která dyslipidemii ovlivňují pozitivně., Štěpán Svačina, and Lit. 39
Cieľ: V práci sme sa zamerali na vedomosti pacientov s astmou v oblastiach self-manažmentu tohto ochorenia a najmä na vplyv faktoru dĺžky trvania tohto ochorenia na úroveň vedomostí o self-manažmente. Zároveň sme zisťovali vzťah medzi úrovňou vedomostí o self-manažmente ochorenia a kontrolou astmy. Metodika: V tejto prierezovej štúdii bolo do súboru zaradených 297 respondentov. Na testovanie kontroly astmy a úrovne vedomostí pacientov sme použili valídne nástroje a to Dotazník vedomostí o self-manažmente astmy pre dospelých (Measuring asthma self-management knowledge in adults) a Test kontroly astmy (Astma Control Test ACTTM). Na štatistické spracovanie dát boli využité: Pearsonov Chi-kvadrat test nezávislosti a Spearmanov korelačný koeficient. Výsledky: Až 220 z 297 respondentov (74,07 %) preukázalo nedostatočné vedomosti, a to konkrétne v doméne Vedomosti o liečbe astmy. V oblasti Manažment bronchiálnej astmy malo nedostatočné vedomosti 191 respondentov (64,31 %). Početnosť správnych odpovedí zároveň naznačuje, že úroveň vedomostí v doménach self-manažmentu astmy, významných pre kontrolu ochorenia, bola vyššia v skupine pacientov diagnostikovaných v priemere jeden rok ako v skupine, ktorá trpí ochorením dlhšie (6-10 rokov), i keď rozdiel nie je štatisticky významný. Záver: Nedostatky vo vedomostiach astmatikov, vyššia frekvencia chýb v oblastiach self-manažmentu, vrátane self-monitoringu a horšia kontrola astmy pri ochorení diagnostikovanom viac ako 6 rokov naznačujú, že je potrebné v klinickej praxi venovať čas a pozornosť reedukácii, opakovanému posúdeniu vedomostí a praktických zručností (aplikácia metód self-manažmentu, inhalačnej techniky) v skupine už skôr diagnostikovaných astmatikov., Aim: This project is aimed to find out the patient knowledge with asthma in the area of self-management of this disease and particularly the influence of the length of the disease on the knowledge level about self-management. At the same time we tried to find out the relation between the knowledge level of the asthma self-management and control of asthma disease. Methods: The total number of 297 adult asthma patients were included in the cross sectional study. The valid instruments Asthma Control Test and Measuring asthma self management knowledge in adults were used for testing asthma control and the degree of patient knowledge in self management of asthma. The Chi-squared test and the Spearman´s rank correlation coefficient were used for statistical processing of data. Results: A total of 220 out of 279 respondents (74%) showed poor knowledge of selfmanagement of asthma, particularly in “Knowledge of asthma treatment” domain and 191 patients in “Management of bronchial asthma” domain (64%). Patients who had been diagnosed one year ago had better level of knowledge in selfmanagement of asthma than those who had been treated for asthma longer than six years (6-10 years). This difference was not significant, but it was related to those domains which has significant influence on asthma control (domains 2-5). Conclusion: Poor knowledge of asthma patients, higher frequency of errors in self management and worse control of asthma in patients with asthma longer than six years imply the need for better and repeated education, check of patient knowledge and skills for self-management, use of peak flow meter included in this group of patients., Michaela Dingová, Petronela Osacká, and Literatura
The aim of this study is to define the possible effects of vegetable oils used as vitamin E vehicle on the electrical activity of the rat heart. To test the possible effects of vitamin E vehicles we studied the effect of i.p. injected corn oil, hazelnut oil or peanut oil on the action potential parameters recorded in both papillary and left atrial muscle strips. Four experimental groups were used. The control group was injected (i.p.) with distilled water, while the three remaining groups received injections of corn oil, hazelnut oil, or peanut oil for five weeks (in a dose of 0.4 ml/kg/day - minimum amount of oil in which vitamin E could be dissolved). We used borosilicated (15-20 MΩ) capillary electrodes and intracellular action potentials (AP) were recorded in isolated papillary and left atrium muscle strips. While administration of three different types of vegetable oil had no significant effect on AP parameters of papillary muscle, they significantly prolonged the repolarization phase of AP in atrial strips. These results show that vegetable oils used as vitamin E vehicles may alter the electrical activity of the heart in a tissue-dependent manner. The present data indicate that the possible effect of vegetable oil vehicles should be kept in mind while evaluating the possible effects of in vivo vitamin E administration., S. Ozdemir, M. Ayaz, T.

The article contains an example detailing the application and analysis of the accuracy of the method called continuous dynamic vehicle weighing during travel, using the telematic system. A model was built using the input data obtained through laboratory experiments on a running vehicle. This model was then applied to study the effects of error probability for the measured input data on the resulting expected accuracy of vehicle weight measuring in a normal running regime. Based on this point, hereby presented is a proposal of selected measured variables of great importance, and a proposal for the computation relationship of the used variables. By statistically processing a set of measured data taken during one vehicle travel, it is possible to attain -10.7% extreme relative error of the given method for the dynamic determination of vehicle weight.
Věkem podmíněná makulární degenerace (VPMD) je v rozvinutých zemích nejčastější příčinou ztráty zraku lidí starších 55 let. Vlhká forma této choroby je příčinou těžké ztráty zraku u 90 % postižených. VPMD vzniká spolupůsobením genetických faktorů a faktorů životního stylu. Klíčovým mechanizmem vzniku vlhké formy VPMD je novotvorba cév, stimulovaná růstovým faktorem VEGF. Léčbou volby VPMD jsou proto preparáty anti-VEGF, podávané formou injekcí do sklivce. V mezinárodních studiích jsou zkoumány nové léky na VPMD. Léčbu je třeba zahájit včas, dokud není vážně postižena zraková ostrost., Age-related macular degeneration (AMD) is the most common cause of vision loss in developed countries in people older than 55 years. The wet form of this disease is the cause of severe vision impairment in 90 percent of patients. AMD develops as a result of an interaction between genetic and lifestyle factors. The key mechanism in the development of wet AMD is the growth of new vessels, stimulated by the vascular endothelial growth factor (VEGF). The treatment of choice is, therefore, the use of anti-VEGF agents administered as intravitreal injections. International clinical studies are evaluating new AMD treatments. It is necessary to start the treatment early, before severe visual impairment occurs., I. Fišer, and Lit.: 20
