Pediatrician carry out the surveillance of language in preschool children as one of the components of child development (language, fine and gross motor skills, etc.). However, language is more than that. The process of transformation of the magic meaning on the word present in the initial stages of human evolution (Myth period) into a new, symbolic meaning as representative of the object (Logos period) took around 40,000 years. With the mastering of language, man was capable of thinking; from then onwards, these two functions, thought and language, became inextricably linked, the evolved hand in hand...

Native biodiversity on the Galapagos Archipelago is severely threatened by invasive alien species. On Santa Cruz Island, the abundance of introduced plant species is low in the arid lowlands of the Galapagos National Park, but increases with elevation into unprotected humid highlands. Two common alien plant species, guava (Psidium guajava) and passion fruit (Passiflora edulis) occur at higher elevations yet their seeds are dispersed into the lowlands by migrating Galapagos tortoises (Chelonoidis spp.). Tortoises transport large quantities of seeds over long distances into environments in which they have little or no chance of germination and survival under current climate conditions...

The golden apple snail, Pomacea canaliculata, is one of the world's 100 most notorious invasive alien species. Knowledge about the critical climate variables that limit the global distribution range of the snail, as well as predictions of future species distributions under climate change, is very helpful for management of snail. In this study, the climatically suitable habitats for this kind of snail under current climate conditions were modeled by biomod2 and projected to eight future climate scenarios (2 time periods [2050s, 2080s] × 2 Representative Concentration Pathways [RCPs; RCP2...

Electronic cigarette (EC) use continues to increase among adolescents. From a primary prevention point of view, an important gap in our knowledge includes determining whether young smokers that use EC maintain a distinct social profile from kids who use combustible cigarettes (CC). Survey data from middle school students in West Virginia, USA were collected between September and November of 2015 (N = 6547, response rate 84.7%) as part of a state wide school-based mental health intervention program. Data was analyzed using multinomial logistic regression for categorical data...

PURPOSE: Little is known about black African (BA) and black African-Caribbean (BAC) men's views towards cancer; yet culture and acculturation can contribute to the way in which people understand, explain and develop their attitudes towards cancer. Hence, cancer prevention and early detection strategies may not be sensitive to United Kingdom (UK)-based black men's views, affecting their awareness of risk factors and early detection services. This study explored the views of UK-based BA and BAC men towards cancer...

Dimorphandra wilsonii, a Cerrado endemic Fabaceae tree, is threatened by land-use changes. The few remaining individuals occur in areas dominated by alien grasses like Urochloa decumbens. We tested the impact of nitrogen (N) availability and symbionts' presence on mitigating the effects of competition from U. decumbens. Dimorphandra wilsonii seedlings were 50-week pot-cultivated under limiting (3mM) or non-limiting (10mM) N, with or without U. decumbens, and inoculated or not with a N-fixer (Bradyrhizobium sp...

Trichocorixa verticalis (T. verticalis), native to North America and the Caribbean islands, is an invasive waterboatman species (Corixidae) in the southwest of the Iberian Peninsula. Previous studies in the native range have suggested that predation by T. verticalis can regulate the abundance of Anostracan and Cladoceran zooplankton in saline ecosystems, causing increases in phytoplankton through a trophic cascade. In this experimental study, we tested the predator-prey relationship between the native brine shrimp Artemia parthenogenetica, and T...

Improving photosynthetic capability is one of the most important factors for increasing wheat yield potential. The photosynthetic capability of wheat germplasm with different alien chromosomes was investigated and compared with bread wheat cultivars (BC) in this study, including wheat addition lines (CA), hexaploid triticale (HT), octoploid triticale (OT), and synthetic hexaploid wheat lines (SHW). Results indicated that HT, OT, and SHW produced significantly higher biomass plant(-1)(BMPP), with HT displaying the highest grain yield plant(-1) (GYPP)...

Although islands are model systems for investigating assembly of biological communities, long-term changes in archipelago communities are not well understood because of the lack of reliable data. By using a vast amount of floristic data we assembled a dataset of the plant species occurring on 16 islands of the Tuscan Archipelago, Italy, across two periods, 1830-1950 and 1951-2015. We collected 10,892 occurrence records for 1,831 species. We found major changes in the island plant assemblages between the two periods, with native flora significantly decreasing (-10...

The sense of body ownership, i.e., the belief that a specific body part belongs to us, can be selectively impaired in brain-damaged patients. Recently, a pathological form of embodiment has been described in patients who, when the examiner's hand is located in a body-congruent position, systematically claim that it is their own hand (E+ patients). This paradoxical behavior suggests that, in these patients, the altered sense of body ownership also affects their capacity of visually discriminating the body-identity details of the own and the alien hand, even when both hands are clearly visible on the table...

The level of invasion (number or proportion of invasive species) in a given area depends on features of the invaded community, propagule pressure, and climate. In this study, we assess the invasive flora of nine islands in the West Indies to identify invasion patterns and evaluate whether invasive species diversity is related to geographical, ecological, and socioeconomic factors. We compiled a database of invasive plant species including information on their taxonomy, origin, pathways of introduction, habitats, and life history...

Human trade and travel are breaking-down biogeographic barriers, resulting in shifts in the geographical distribution of organisms, yet it remains largely unknown whether different alien species generally follow similar spatiotemporal colonization patterns and how such patterns are driven by trends in global trade. Here, we analyse the global distribution of 241 alien ant species and show that these species comprise four distinct groups that inherently differ in their worldwide distribution from that of native species...

The Clustered regularly interspaced short palindromic repeats (CRISPR) systems are a type of innate immunity found in some prokaryotes, which protect them against alien genetic elements by targeting foreign nucleic acids. Some other functions are also attributed to these systems. Clostridium botulinum bacteria produce botulinum neurotoxins (BoNT), one of the deadliest known toxins for humans and some animals. Food poisoning due to these bacteria is still a challenge in food industries. On the other hand, BoNT has been widely investigated for therapeutic applications including different muscle disorders...

A growing body of research has shown people who hold anomalistic (e.g., paranormal) beliefs may differ from nonbelievers in their propensity to make probabilistic reasoning errors. The current study explored the relationship between these beliefs and performance through the development of a new measure of anomalistic belief, called the Anomalistic Belief Scale (ABS). One key feature of the ABS is that it includes a balance of both experiential and theoretical belief items. Another aim of the study was to use the ABS to investigate the relationship between belief and probabilistic reasoning errors on conjunction fallacy tasks...

BACKGROUND: Infertility as a gynecological illness causes many psychological problems. In Turkey, only a limited number of studies have used qualitative methods to explore the experiences of infertile women. PURPOSE: The aims of this study are to investigate the infertility experiences of women using Watson's Theory of Human Caring as a guide and to sensitize healthcare professionals to the importance of the personal stories of these women. METHODS: A phenomenological approach was used to guide our exploration of the stories of infertile women during their treatment for infertility...

BACKGROUND: Midlife, a significant developmental phase for women, is a period of biological, psychological, and social role changes. However, not all women transition smoothly into middle age, with those who experience depression typically bearing significantly greater physical and psychological discomforts in midlife. Despite the expanding body of research on women and depression, little is understood about how depressed women handle the midlife transition. PURPOSE: The aim of this study was to gain a deeper understanding about the lived experience of middle-aged women with major depression...

Suicide is ranked as the tenth leading cause of death for all ages in the United States (Centers for Disease Control and Prevention, 2012). Joiner's (2005) interpersonal theory of suicide stated thwarted belongingness-the feeling of being alienated from others-and perceived burdensomeness-the feeling of being a liability to others-are the primary proximal factors leading to suicidal desire. The current study focused on thwarted belongingness and examined its relationship to face-to-face interactions and online interactions in both an undergraduate and community sample...

BACKGROUND: A neglected aspect of alien invasive plant species is their influence on mosquito vector ecology and malaria transmission. Invasive plants that are highly attractive to Anopheles mosquitoes provide them with sugar that is critical to their survival. The effect on Anopheles mosquito populations was examined through a habitat manipulation experiment that removed the flowering branches of highly attractive Prosopis juliflora from selected villages in Mali, West Africa. METHODS: Nine villages in the Bandiagara district of Mali were selected, six with flowering Prosopis juliflora, and three without...

The aim of the present paper is to experimentally test whether sound symbolism has selective effects on labels with different ranges-of-reference within a simple noun-hierarchy. In two experiments, adult participants learned the make up of two categories of unfamiliar objects ('alien life forms'), and were passively exposed to either category-labels or item-labels, in a learning-by-guessing categorization task. Following category training, participants were tested on their visual discrimination of object pairs...

The main goal of synthetic biology (SB) is the creation of biodiversity applicable for biotechnological needs, while xenobiology (XB) aims to expand the framework of natural chemistries with the non-natural building blocks in living cells to accomplish artificial biodiversity. Protein and proteome engineering, which overcome limitation of the canonical amino acid repertoire of 20 (+2) prescribed by the genetic code by using non-canonic amino acids (ncAAs), is one of the main focuses of XB research. Ideally, estranging the genetic code from its current form via systematic introduction of ncAAs should enable the development of bio-containment mechanisms in synthetic cells potentially endowing them with a "genetic firewall" i...
