Ischemic Complications

Surgical treatment remains the only way to primary prevention of intracranial hemorrhage in patients with cerebral aneurysms. The implementation of such interventions is associated with the risk of the development of secondary cerebral circulation disorders. The effect of ischemic damage to cerebral structures on the state of mental functions and the quality of life of patients is currently not well understood. The interrelation of the formation of foci of cerebral infarction according to magnetic resonance imaging and the dynamics of the state of cognitive functions of patients undergoing surgery for unruptured cerebral aneurysms is considered. It has been established that «fresh» foci of ischemic damage are formed in a third of patients. Among patients operated on with intravascular access, brain infarction zones are formed in half of the patients. Endovascular interventions under balloon assistance are associated with a high risk of asymptomatic ischemic complications. When comparing the results of neuropsychological examination in patients with diagnosed foci of cerebral infarction and the group where the ischemic complications were absent, no significant differences were found. According to the neuropsychological examination, the results before and after the operation did not differ significantly in patients with infarction foci. Thus, after surgery for unruptured aneurysms, local foci of cerebral infarction are often detected. In most cases, these changes are not associated with the deterioration of the higher mental functions of patients and are asymptomatic.

Ген APOE - это один из наиболее известных генов, ассоциированных с развитием как сердечно-сосудистых, так и нейродегенеративных заболеваний центральной нервной системы, сопровождающихся нарушением когнитивных функций (КФ). В ходе настоящего исследования изучены ассоциации аллелей гена APOE с нарушением КФ у подростков г. Новосибирска. Состояние КФ было оценено у 231 мальчика (42,1%) и у 318 девочки (57,9%). Их средний возраст составил 15,66 ± 0,9 года. Выявлено, что наличие аллеля Е4 оказывает негативное влияние на состояние рабочей памяти уже в подростковом возрасте. The APOE gene is one of the most famous genes associated with the development of both cardiovascular diseases and neurodegenerative diseases of the central nervous system, accompanied by impaired cognitive functions. In the course of this study, the associations of APOE gene alleles with cognitive functions violation in the adolescent population of Novosibirsk were studied. The state of cognitive functions was evaluated in 231 boys (42.1%) and 318 girls (57.9%). Their average age was 15.66 ± 0.9 years. It was revealed that the presence of the E4 allele of the APOE gene has a negative effect on the state of working memory even in adolescence.

This paper describes a methodology for implementing the state estimation and enhancing the accuracy in large-scale power systems that partially depend on variable renewable energy resources. To determine the actual states of electricity grids, including those of wind and solar power systems, the proposed state estimation method adopts a fast-decoupled weighted least square approach based on the architecture of application common database. Renewable energy modeling is considered on the basis of the point of data acquisition, the type of renewable energy, and the voltage level of the bus-connected renewable energy. Moreover, the proposed algorithm performs accurate bad data processing using inner and outer functions. The inner function is applied to the largest normalized residue method to process the bad data detection, identification and adjustment. While the outer function is analyzed whether the identified bad measurements exceed the condition of Kirchhoff’s current law. In addition, to decrease the topology and measurement errors associated with transformers, a connectivity model is proposed for transformers that use switching devices, and a transformer error processing technique is proposed using a simple heuristic method. To verify the performance of the proposed methodology, we performed comprehensive tests based on a modified IEEE 18-bus test system and a large-scale power system that utilizes renewable energy.

A double-blind placebo trial was conducted to determine the effect of moderate to high loads ofTrichuris trichiura(whipworm) infection on the cognitive functions of 159 school children (age 9–12 years) in Jamaica. Infected children were randomly assigned to Treatment or Placebo groups. A third group of randomly selected uninfected children were assigned to a Control for comparative purposes. The improvement in cognitive function was evaluated using a stepwise multiple linear regression, designed to control for any confounding variables. The expulsion of worms led to a significant improvement in tests of auditory short-term memory (P< 0.02;P< 0.01), and a highly significant improvement in the scanning and retrieval of long-term memory (P< 0.001). After 9 weeks, treated children were no longer significantly different from an uninfected Control group in these three tests of cognitive function. The removal ofT. trichiurawas more important thanAscaris lumbricoidesin determining this improvement. The results suggest that whipworm infection has an adverse effect on certain cognitive functions which is reversible by therapy.

The scientific article is devoted to the coverage of the administrative procedure for providing electronic services by the State Architectural and Construction Inspectorate of Ukraine. Different approaches to the concept of administrative procedure in terms of e-services provision are discussed. The stages of the procedure of providing electronic service in the form of submission of a declaration (notification) by individuals are characterized. It is established that before commencing the process of submission of the declaration (message), the service consumer must have a personal key and a valid enhanced certificate, which will be used during the submission process to affix an electronic digital signature to the form with the declaration (message). You can obtain enhanced key certificates at an accredited key certification center. Thus, at the moment the service supports certificates issued by the certification center of the information and reference department of the Ministry of Revenue and Collections of Ukraine. Install a Java computing software package on your computer and enable JavaScript scripts to run in your browser. Please note that detailed Java installation instructions are available at http://java.com/download/installed.jsp. You can download Java directly for Windows from http://www.java.com/download/windows_xpi.jsp. How to enable JavaScript scripts in your browser (http://www.enable-javascript.com/en/). It is concluded that the procedure of providing the service in electronic form, for example, the submission of a declaration (notification) by the state architectural and construction inspection of Ukraine is regulated in detail on the official website and still needs to improve the quality of the provision of these services in the form of simplification and accessibility for all consumers services.

Abstract Platynosomiasis is a hepatopathy caused by Platynosomum illiciens(= P. fastosum) (Trematoda: Dicrocoelidae), which occurs mainly in domestic and wild cats in tropical and subtropical areas. The objective of this study was to verify the occurrence of P. illiciens infection in domestic cats in the city of Araguaína, Tocantins, Brazil, using necropsy and coproparasitological tests. Additionally, we aimed to evaluate the use of two different techniques to diagnose P. illiciens infection in domestic cats and verify whether this parasitism was associated with individual feline characteristics. For this, 54 cats of different ages were analyzed. The percentage of infection was 33.3% (CI = 21.1-47.5%), parasite load was 9-509, mean intensity was 151.7, and mean abundance was 50.5 trematodes per animal. The risk of infection was higher for females than for males (OR = 5.00; P = 0.017). The spontaneous sedimentation coproparasitological test demonstrated the greatest sensitivity and specificity in diagnosing P. illiciens. This study is the first to report the occurrence of P. illiciens in cats in the state of Tocantins, northern Brazil.

My dear Sir,—In a letter which I had the honour to address to you last year "On the Ova of the Salmon in relation to the distribution of Species,” I have expressed the hope that some of the results of observations therein described may aid in solving the question as to the period, the age, at which the impregnated ova of fish are most retentive of life, and consequently are in the state best fitted for transport without loss of life. Joining with you in considering the subject in need of and deserving further inquiry, I have taken the earliest opportunity that has offered of resuming it. The experiments which I have made, and which I shall now describe, have been more limited than I could have wished, having been confined to the ova of the Charr, as I was not able to obtain the ova of the Salmon or any of its congeners in a fit state for the trials required.

Temporal Control Of Movement

The purpose of this study was to investigate the temporal control of repetitive tapping in children, ages 3 to 11 ( N = 99). The subjects tapped in synchrony with an auditory pulse (synchronizing phase) at nine different tempos (interpulse intervals of 370, 420, 500, 540, 620, 720, 850, 1000, and 1300 msec.) and were then asked to maintain the same tapping tempo without the aid of an auditory pulse (continuing phase). The time difference between the onset of the pulse and the tap in the synchronizing phase and intertap interval in the continuing phase were measured. Both the time difference between the timing pulse and the tap, and variation of intertap intervals were smallest at the tempo of 500 msec. for all age groups. The variation of the intertap interval at slower tempos was greater than that at fast tempos in all age groups. This suggests that the accurate interval (tempo) of all the subjects was around 500 to 600 msec At slower tempos, the intertap interval had a tendency to become slightly shorter with time and converged at intertap interval 500 to 600 msec. It is suggested that the preferred tempo was superior to the prescribed tempo in the continuing phase for younger subjects. Differing patterns of response in the movement sequence were observed between younger and older subjects in the movement sequence. The changes in temporal control over the age groups are thought to appear at between 5 and 7 years of age.
