Objectives: The document aims to study the relations between psychosocial environment and health risk behaviors (cigarette smoking, alcohol consumption, drunkenness, perpetration of intimidation and early start of sex life) in a representative sample of Bulgarian teenagers .
Methods: We apply multilevel analysis, using Bulgarian health behavior data 2017/2018 in the study of school age children (HBSC).
Results: There is a significant variation between the schools of Bulgaria in the proportions of students who smoke cigarettes, drink alcohol, are drunk and have an early start of sex life. The satisfaction of the lower school is considerably associated with chances of smoking and higher drunkenness. The effect of the pressure of the school differs for the perpetration of smoking and intimidation. The effect of student assistance also differs for certain types of health risk behaviors. The support of higher students is positively associated with frequent consumption of alcohol and drunkenness. The relationship between teacher support and alcohol abuse is negative.
Conclusions: There is an important association between the characteristics of the psychosocial school environment and the health behaviors of Bulgarian adolescents (smoking, alcohol consumption, intoxication, perpetration of intimidation). Global and efficient health promotion policies in Bulgarian schools are needed to facilitate healthy lifestyles. The most commonly heterogeneous and clinically heterogeneous carcinomas and the most common malignant tumor of the urinary tract in developed countries in the world, where several control point cubes as a ligand-1 programmed death (PD- L1) and programmed cell death proteins (PD- 1) received the most attention in the treatment of bladder cancer. However, the clinical impact of this biomarker has not yet been established.
Contribution of metabolic syndrome components to cognitive performance in middle-aged adults
The metabolic syndrome (dishes) has been associated with altered cognition in different cognitive domains. This study investigated the association between diseases and the cognitive functioning of middle-aged Bubarians on different definitions of the severity of dishes. Our transverse sample included 112 participants (67 without briefcase and 45 with maletics) with an average age of 50.04 ± 3.31 years. The following method variables have been considered as the presence of dishes, permanently measured dishes, dichotomized dishes components, the number of dishes components present and the gravity score of metabolic syndrome (MSSS). The cognitive performance of the participants was evaluated using the consortium to establish a register of the neuropsychological battery of Alzheimer’s disease (CERAD-NB).
We used multivariate regression models to investigate associations between different measures of the severity of the dishes and total and CERAD-NB sub-test scores. On several definitions, the dishes have been associated with lower cognitive functioning and the severity of the bets appeared to be a better predictor than most components of the MET. Recognition and reduction of the severity of dishes components may be useful for supporting cognitive operation. Additional longitudinal research is needed to lose more light on the relationship between dishes and cognitive functioning throughout the life. This document includes a catalog of the type of genuine butterflies (papironoida) kept in the National Museum of Natural History at the Bulgarian Academy of Sofia Sciences.
The collection contains types of nine group taxa of nominal species, described by S. Abadjiev, S. Beshkov, I. Buresch, H. Rebel and K. Tuxchkow. The lectotypes have been designated for colias myrmidone Balcanica Rebel, 1901, Erebia Tyndarus Macedonica Buresch, 1919, E. Pirinica Buresch, 1919, Euchloe Gruneri Macedonica Buresch, 1921, Sathusa Strumata Buresch, 1919 and Dorite Apollinus Var. Thracica Buresch, 1915.
Psychosocial school environment and health risk behaviours of adolescents in Bulgaria: results from multilevel analysis
NMR profiling of North and Bulgarian Macedonian honeys for the detection of botanical and geographical origin
Bulgaria and North Macedonia have a long history of the production and use of honey; However, there is a clear lack of systematic and deepened research on honey from both countries. Honey oak honey is of particular interest because it is highly appreciated by consumers because of its health benefits. The objective of this study was to characterize honey and floral honey from Bulgaria and North Macedonia based on their NMR profiles. The 1D and 2D 1H and 13C-NMR spectra were measured by 16 North Macedonian honey samples and 22 Bulgarian honey samples.
In total, 25 individual substances have been identified, including quinovose, which was found for the first time at honey. Chemometric methods (PCA-main component analysis, pls-da-partial discriminating analysis, Anova-analysis of the variance) were used to detect the similarities and differences between samples, as well as to determine their botanical origin and geographical. Semicarative data on individual sugars and some other constituents have been obtained, which allowed the reliable classification of honey samples by botanical and geographical origin, based on chemometric approaches.

The results allowed us to distinguish the honey honey oak from other types of honey and determine the country of origin. The NMR was a fast and practical method, thus avoiding the need for other more tedious analytical techniques. The first Bulgarian retrospective study of hospitalized patients of COVID-19 was presented. Age, male sex, comorbidity and signs of dyspnea and nausea have been estimated as higher risk factors for a serious form. The anomaly in inflammatory markers was associated with a poor progression of the disease.
