The report reveals the impact of tourism on changing national identity. The interaction between tourism and cultural identity as social phenomena is noted. Globalization as a prerequisite for ...cultural disorientation is examined. The concept of anthropotok, as a mass self-sustaining process of identity change, is examined.
According to scientific experts, in the coming years humanity will be in a process of general demographic transition, after which either the population of the planet will stabilize or an era of ...slight, prolonged and monotonous decline will begin. The reason for all this is the anthropogenic flow, which is gradually becoming an object of state administration, and at the same time is at the center of the scientific report.

The history of mankind is inextricably linked to the migration of huge masses of people from their native places to other territories. Migration is a set of different in nature territorial ...displacements of the population, which lead to a change of residence. Despite the constraints posed by the COVID-19 pandemic, migrants continue to make secret journeys, fleeing war, violence and poverty.
The citizens of the Republic of Bulgaria, as sovereign of state power, worried by the continuing lack of continuity in the conduct of state policy, the confrontation and division in society, the ...diminishing confidence in the institutions and the lack of leadership, finding and finding that the main challenges facing society today are the problems of poverty, the declining competitiveness of the country, migration, the demographic crisis, education, health and the strengthening of the state which directly affects the security of the state and the citizens and the sustainability of the nation, which are caused by the absence of a national ideal and national doctrine.

Extracts from medicinal plants are widely used in the treatment and prevention of different diseases.
is a Balkan endemic species with reported antioxidant and antimicrobial characteristics; however, ...its phytochemical composition is not well defined. Here, we examined the metabolome of
by chromatography-mass spectrometry (GC-MS), ultra-performance liquid chromatography-mass spectrometry (UPLC-MS-MS), and inductively coupled plasma mass spectrometry (ICP-MS). Amino acids, organic acids, sugars, and sugar alcohols were the primary metabolites with the highest levels in the plant extract. Detailed analysis of the sugar content identified high levels of sucrose, glucose, mannose, and fructose. Lipids are primary plant metabolites, and the analysis revealed triacylglycerols as the most abundant lipid group. Potassium (K), magnesium (Mg), zinc (Zn), and calcium (Ca) were the elements with the highest content. The results showed linarin, 3-caffeoil-quinic acid, and rosmarinic acid, as well as a number of polyphenols, as the most abundant secondary metabolites. Among the flavonoids and polyphenols with a high presence were eupatorin, kaempferol, and apigenin-compounds widely known for their bioactive properties. Further, the acute toxicity and potential anti-inflammatory activity of the methanolic extract were evaluated in Wistar rats. No toxic effects were registered after a single oral application of the extract in doses of between 200 and 5000 mg/kg bw. A fourteen-day pre-treatment with methanolic extract of
in doses of 250, 400, and 500 mg/kg bw induced anti-inflammatory activity in the 1st, 2nd, and 3rd hours after carrageenan injection in a model of rat paw edema. This effect was also present in the 4th hour only in the group treated with a dose of 500 mg/kg. In conclusion,
extract is particularly rich in linarin, rosmarinic acid, and flavonoids (eupatorin, kaempferol, and apigenin). Its methanolic extract induced no toxicity in male Wistar rats after oral application in doses of up to 5000 mg/kg bw. Additionally, treatment with the methanolic extract for 14 days revealed anti-inflammatory potential in a model of rat paw edema on the 1st, 2nd, and 3rd hours after the carrageenan injection. These results show the anti-inflammatory potential of the plant, which might be considered for further exploration and eventual application as a phytotherapeutic agent.
