13. PLURILINGUAL SOCIAL NETWORKS AND THE CREATION OF HYBRID CULTURAL SPACES
RESUMO Embora o plurilinguismo seja um tema bem estabelecido na literatura internacional, principalmente em situações de mobilidade transnacional, ainda sabemos pouco sobre a aprendizagem e apropriação de formas não padrão de inglês por jovens brasileiros online. Ao contrário dos usos instrumentais que predominam no ensino formal de língua inglesa,

14. Egocentric and allocentric spatial memory in healthy aging: performance on real-world tasks
Although normal aging has been related to several cognitive difficulties, other processes have been studied less, such as spatial memory. Our aim was to compare egocentric and allocentric memory in an elderly population using ecological tasks. Twenty-eight cognitively unimpaired participants performed Egocentric and Allocentric Spatial Memory Tasks, as well

15. Multivariate Analysis and Machine Learning in Properties of Ultisols (Argissolos) of Brazilian Amazon
ABSTRACT: Ultisols are the most common soil order in the Brazilian Amazon. The Legal Amazon (LA) has an area of 5 × 106 km2, with few accessible areas, which restricts studies of soils at a detailed level. The pedological properties can be estimated more efficiently using statistical procedures and machine learning techniques, tools which are capable of rec

16. Anchusa italica extract: phytochemical and neuroprotective evaluation on global cerebral ischemia and reperfusion
Abstract Stroke is the third leading cause of mortality and disability in industrial countries. Treatment with herbs with antioxidant properties has been reported to be an alternative to the conventional treatments. This study was conducted to investigate the effect of Anchusa italica extract on hippocampal injury induced by transient global cerebral ischemi

17. Chronic intermittent exposure to ayahuasca during aging does not affect memory in mice
The Quechua term ayahuasca refers to a beverage obtained from decoctions of the liana Banisteriopsis caapi with leaves of Psychotria viridis. The ritualistic use of ayahuasca is becoming a global phenomenon, with some individuals using this beverage throughout life, including in old age. Cognitive impairment is a common manifestation during aging. There are

18. Learning of Teaching in the Professional Socialization in Physical Education
Abstract AIMS to investigate how the professional socialization happens through teacher education. METHODS a qualitative research, descriptive, was developed using exploratory interview and narrative interview to clarify and deepen the collected information. Two Physical Education teachers with different stories of personal and professional development par

19. Hippocampal overexpression of Down syndrome cell adhesion molecule in amyloid precursor protein transgenic mice
Down syndrome cell adhesion molecule (DSCAM) is located within the Down syndrome critical region of chromosome 21. DSCAM is a broadly expressed neurodevelopmental protein involved in synaptogenesis, neurite outgrowth, and axon guidance. We previously demonstrated DSCAM overexpression in the cortex of amyloid precursor protein (APP) transgenic mice, suggestin

20. Influence of schooling and age on cognitive performance in healthy older adults
Few studies have examined the influence of a low level of schooling on age-related cognitive decline in countries with wide social and economic inequalities by using the Cambridge Automated Neuropsychological Test Battery (CANTAB). The aim of the present study was to assess the influence of schooling on age-related cognitive decline using unbiased cognitive

21. Maternal Exercise during Pregnancy Increases BDNF Levels and Cell Numbers in the Hippocampal Formation but Not in the Cerebral Cortex of Adult Rat Offspring
Clinical evidence has shown that physical exercise during pregnancy may alter brain devel- opment and improve cognitive function of offspring. However, the mechanisms through which maternal exercise might promote such effects are not well understood. The present study examined levels of brain-derived neurotrophic factor (BDNF) and absolute cell num- bers in

22. Behavioral alterations induced by repeated saxitoxin exposure in drinking water
Abstract Background Blooms of the saxitoxin-producing cyanobacterium Cylindrospermopsis raciborskii have been contaminating drinking water reservoirs in Brazil for many years. Although acute effects of saxitoxin intoxication are well known, chronic deleterious outcomes caused by repeated saxitoxin exposure still require further investigation. The aim of th

23. Puerarin protects against damage to spatial learning and memory ability in mice with chronic alcohol poisoning
We evaluated the effect of puerarin on spatial learning and memory ability of mice with chronic alcohol poisoning. A total of 30 male C57BL/6 mice were randomly divided into model, puerarin, and control groups (n=10 each). The model group received 60% (v/v) ethanol by intragastric administration followed by intraperitoneal injection of normal saline 30 mi

24. Possible roles of COX-1 in learning and memory impairment induced by traumatic brain injury in mice
People who suffer from traumatic brain injury (TBI) often experience cognitive deficits in spatial reference and working memory. The possible roles of cyclooxygenase-1 (COX-1) in learning and memory impairment in mice with TBI are far from well known. Adult mice subjected to TBI were treated with the COX-1 selective inhibitor SC560. Performance in the open f
