This article is a broad review focused on dragon trees—one of the most famous groups of trees in the world, well known from ancient times. These tertiary relicts are severely endangered in most of the area where they grow. The characteristic features of the dragon tree group are described and the species belonging to this group are listed. This review gathers together current knowledge regarding the taxonomy, evolution, anatomy and morphology, physiology, and ontogeny of arborescent dragon tree species. Attention is also paid to the composition, harvesting, medicinal, and ethnobotanical use of the resin (dragons’ blood). An evaluation of population structure, distribution, ecology, threats, and nature conservation forms the final part of the review. In the conclusions we recommend further avenues of research that will be needed to effectively protect all dragon tree species.

ABSTRACT Epilepsy is one of the most dreaded and terrifying human afflictions. One of the many names it has received was Sacred Disease, during Greek times. Heracles served as a source of the divine connotation that epilepsy received in ancient times, as he was one of the most important demigods in Greek mythology. However, several authors have attributed Heracles’ actions to a seizure, including Hippocrates, who described the sacred disease on his “Corpus Hippocraticum.” This paper reviewed some of the publications on the myth and content of the text of Hippocrates, in relation to the current knowledge of the disease.

From ancient times till nowadays information plays a key role in the political processes. The beginning of XXI century demonstrated the transformation of global security from military to information, social etc. aspects. The widening of pandemic demonstrated the weaknesses of contemporary authoritarian states and the power of human-oriented states. During the World War I the theoretical and practical interest toward political manipulation and political propaganda grew definitely. After 1918 the situation developed very fast and political propaganda became the part of political influence. XX century entered into the political history as the millennium of propaganda. The collapse of the USSR and socialist system brought power to new political actors. The global architecture of the world has changed. Former Soviet republic got independence and tried to separate from Russia. And Ukraine was between them. The Revolution of Dignity in Ukraine was the start point for a number of processes in world politics. But the most important was the fact that the role and the place of information as the challenge to world security was reevaluated. The further annexation of Crimea, the attempt to legitimize it by the comparing with the referendums in Scotland and Catalonia demonstrated the willingness of Russian Federation to keep its domination in the world. The main difference between the referendums in Scotland and in Catalonia was the way of Russian interference. In 2014 (Scotland) tried to delegitimised the results of Scottish referendum because they were unacceptable for it. But in 2017 we witness the huge interference of Russian powers in Spain internal affairs, first of all in spreading the independence moods in Catalonia. The main conclusion is that the world has to learn some lessons from Scottish and Catalonia cases and to be ready to new challenges in world politics in a format of information threats.

The article shows that knowledge of the site of a particular forest stand, together with research results and experience, can provide information that is important for the cultivation of mountain forests, including knowledge of the composition of the tree species and the structure and growth capacity of natural forest. Furthermore, certain sites can, thus, be characterized by factors that influence restocking, such as snow mould,lush ground vegetation or low temperature. The guidelines«minimale Pflegemassnahmen» – «Minimal tending of protection forests» (WASSER und FREHNER, 1996) are based on this principle. For individual sites, warnings about natural dangers such as rock fall or statements concerning nature conservation can be made (e.g., the occurrence of tree species, suitability as a biotope for Capercaille). In conclusion, two research projects on the relationship between site and natural dangers will be presented.

The Mimosa genus belongs to the Fabaceae family of legumes and consists of about 400 species distributed all over the world. The growth forms of plants belonging to the Mimosa genus range from herbs to trees. Several species of this genus play important roles in folk medicine. In this review, we aimed to present the current knowledge of the ethnogeographical distribution, ethnotraditional uses, nutritional values, pharmaceutical potential, and toxicity of the genus Mimosa to facilitate the exploitation of its therapeutic potential for the treatment of human ailments. The present paper consists of a systematic overview of the scientific literature relating to the genus Mimosa published between 1931 and 2020, which was achieved by consulting various databases (Science Direct, Francis and Taylor, Scopus, Google Scholar, PubMed, SciELO, Web of Science, SciFinder, Wiley, Springer, Google, The Plant Database). More than 160 research articles were included in this review regarding the Mimosa genus. Mimosa species are nutritionally very important and several species are used as feed for different varieties of chickens. Studies regarding their biological potential have shown that species of the Mimosa genus have promising pharmacological properties, including antimicrobial, antioxidant, anticancer, antidiabetic, wound-healing, hypolipidemic, anti-inflammatory, hepatoprotective, antinociceptive, antiepileptic, neuropharmacological, toxicological, antiallergic, antihyperurisemic, larvicidal, antiparasitic, molluscicidal, antimutagenic, genotoxic, teratogenic, antispasmolytic, antiviral, and antivenom activities. The findings regarding the genus Mimosa suggest that this genus could be the future of the medicinal industry for the treatment of various diseases, although in the future more research should be carried out to explore its ethnopharmacological, toxicological, and nutritional attributes.

Introduction:Dementia has become a worldwide concern. According to the World Health Organization, there are 50 million individuals suffering from dementia across the world and approximately 20 million new cases are diagnosed each year. The efficacy of medications in controlling agitation and psychotic symptoms is modest and may cause serious adverse effects, outlining the urge for new treatment methods for patients with dementia. Music therapy (MT) is a nonpharmacologic strategy that is used in patients with early-to-late stages of dementia with promising results.Objectives:The aim of this presentation is to evaluate the benefits of music therapy in cognitive functioning and neuropsychiatric symptoms in patients diagnosed with dementia. We also summarize the current knowledge about this topic.Methods:A non-systematic review of the literature was performed on PubMed, PsycINFO and Web of science using selected keywords.Results:MT sustains its benefit because musical memory regions in the brain are relatively spared compared to cognitive function. “Musical memories” can, thus, be stored longer than non-musical memories, allowing to recall associated life events and emotions. Systematic reviews suggest that MT seem to have a positive effect on symptoms such as depression, anxiety and behavioral problems while the findings concerning agitation/aggression are inconsistent. No large differences were found between studies using live or recorded music although the latter reported more of a consistently positive impact on behavioral and psychological outcomes. The studies using live music, however, reported specific benefits to relationships and interactions.Conclusions:The majority of the studies have methodological limitations, making it difficult to offer firm conclusions. Despite this, there were positive results on aspects of quality of life, cognitive function, behavioral, psychological, physiological and communication outcomes.

This article aims to examine the legacy and policy of AK Party in Turkey, Ennahda’s political movement in Tunisia, and Jamaat-e-Islami (BJI) in Bangladesh, which is ostensibly identified with Islamic political ideology and acquainted with the world as a ‘moderate-conservative political Islam party.’ The study interrogates the nature, processes, and the characteristic features of the three countries’ administrative system, comparatively from three regions of the world, particularly from the Middle East and Europe region, Africa and Arab region, and the South Asian region. This study also highlights these political parties’ history, political ideology differences, and their practices reflective of democratic principles from a theoretical perspective on politics, policy, and philosophy. It also acknowledges whether the political development of Turkey from 2002 onward is feasible for Bangladeshi and Tunisian Islamic political parties to accept as a role model in their political arena.

The incidence and severity of obesity are rising in most of the world. In addition to metabolic disorders, obesity is associated with an increase in the incidence and severity of a variety of types of cancer, including breast cancer (BC). The bidirectional interaction between BC and adipose cells has been deeply investigated, although the molecular and cellular players involved in these mechanisms are far from being fully elucidated. Here, we review the current knowledge on these interactions and describe how preclinical research might be used to clarify the effects of obesity over BC progression and morbidity, with particular attention paid to promising therapeutic interventions.

Basically through population pressures leading to habitat encroachment and commercial slaughter, India is becoming poorer, day be day, in her still-rich heritage of wildlife. Virgin forests on the plains and in the hilly regions are dwindling. Unfortunately, education and research centres have not cared to educate the youth of the country about the importance of nature conservation.The Author's field endeavours, extending over more than a decade, have helped to reveal that 18 of India's 27 threatened mammalian species—lion-tailed Macaque, Macaque, Nilgiri Langur, Golden Langur, Snub-nosed Langur, Wolf, Asiatic Wild Dog, Malabar Large-spotted Civet, Clouded Leopard, Indian Tiger, Leopard, Snow Leopard, Asian Elephant, Sumatran Rhinoceros, Kashmir Stag, Gaur, Wild Yak, Nilgiri Tahr, and Markhor—have their homes in hilly or montane habitats. Pradoxically, India has the dubious distinction of ranking second in the world, and first among the 15 countries of the Oriental region, in having 27 mammalian species whose world populations are to some extent threatened according to the Red Data Book (IUCN, 1972).

McDowell carries on the dialogue with Kant opened by Sellars and Strawson. He is particularly interested in Kant's idea of intuition as an impression that is already an actualization of the conceptual capacities exercised by the knowing subject in judging. It enables him to release the contemporary discussion on intentionality from the stalemate between bald naturalism and coherentism. Because of the issues raised by both philosophers and some features of their arguments, it is undoubted that Mc- Dowell belongs to the Kantian heritage and exploits some of its elements. The final part of the essay aims at showing that these have in their original context a stronger und more definite meaning than in McDowell's proposal, and that it could be what we are in need of to make the latter more accurate.
