This review article discusses some problems and needs for clarification that are connected with the use of the concepts culture, language, tool, and communication in Daniel Everett’s recently published book, Language: The Cultural Tool. It also discusses whether the idea of biological readiness and preparedness for language (rather than grammar) can really be disposed of as a result of Everett’...

The relative importance of nature and nurture for various forms of expertise has been intensely debated. Music proficiency is viewed as a general model for expertise, and associations between deliberate practice and music proficiency have been interpreted as supporting the prevailing idea that long-term deliberate practice inevitably results in increased music ability. Here, we examined the ass...

Much evidence indicates that men experienced an evolutionary history of physical competition, both one-on-one and in coalitions. We thus hypothesized that, compared to girls and women, boys and men will possess a greater motivational predisposition to be interested in sports, especially team sports. According to most scholars, advocacy groups, and the United States courts, however, this hypothe...

Bipolar is a severe psychiatric disorder which ethiopathogenesis remains unclear. Despite a clearly established heritability, genetic studies have failed to elucidate the underlying mechanism of bipolar disorder, most likely due to the contributing role of environmental factors in the genesis of the disease.. Environmental factors have been consistently described to induce immuno-inflammation d...

Atopic dermatitis (AD, also known as atopic eczema) is driven by a complex relationship between genetic predisposition and environmental exposures. We sought to determine the impact of specific climatic factors on the prevalence of AD in the United states. We used a merged analysis of the 2007 National Survey of Children's Health (NSCH) from a representative sample of 91,642 children aged 0-17 ...

This article reviews and updates current information on the possible genetic basis for cutaneous lupus erythematosus. The aetiology of this condition remains unknown and is believed to be multifactorial, involving genetic, environmental and retroviral factors. A genetic predisposition is probably the greatest risk factor for this condition. Individual susceptibility to lupus erythematosus may b...

Infertility is one of the most serious social problems facing advanced nations. In general, approximate half of all cases of infertility are caused by factors related to the male partner. To date, various treatments have been developed for male infertility and are steadily producing results. However, there is no effective treatment for patients with nonobstructive azoospermia, in which there is...

BACKGROUND Polycystic ovarian syndrome (PCOS) is a controversial endocrine pathology and, recently, it has been suggested that the condition is hereditary. The aim of this study was to prospectively determine in daughters of patients with PCOS, by ultrasonographic (US) and colour Doppler analyses, the incidence of polycystic ovaries and search any correlation with specific hormonal parameters. ...

Environmental influences such as perinatal stress have been shown to program the developing organism to adapt brain and behavioral functions to cope with daily life challenges. Evidence is now accumulating that the specific and individual effects of early life adversity on the functional development of brain and behavior emerge as a function of the type, intensity, timing and the duration of th...
