The regeneration of vessels and their development occur in places of their destruction. This phenomenon suggests that the destruction process itself stimulates vascular development and entails tissue healing and self-repair. Understanding the phenomena of self-repair is extremely important in the process of restoring tissues and organs to the proper functioning of individual organs and the entire body. Therefore, the recognition of angiogenesis processes seems to be the key in the treatment of many diseases.

The current article is included in the larger research “The linguistic structure of binomial botanical denominations– specific epithet”, based on “Conspectus of the Bulgarian vascular flora”, fourth revised and updated edition, Sofia, 2012, and deals with a less common type of specific epithets - nouns in the genitive case. The epithets are organized alphabetically in several groups according to their semantic.

Sleep is an important part of the bodys recuperation and energy accumulation, and the quality of sleep also has a significant impact on peoples physical and mental state during the epidemic of Coronavirus Disease. It has attracted increasing attention how to improve the quality of sleep and reduce the impact of sleep related diseases on health. The electroencephalogram (EEG) signals collected during sleep belong to spontaneous EEG signals. Spontaneous sleep EEG signals can reflect the body own changes, which is also an important basis for diagnosis and treatment of related diseases. Therefore, the establishment of an effective model for classifying sleep EEG signals is an important auxiliary tool for evaluating sleep.

Pulmonary rehabilitation (PR) is a non-pharmacological intervention addressed to chronic obstructive pulmonary disease (COPD) and non-COPD chronic respiratory patients, a key management strategy scientifically demonstrated to improve exercise capacity, dyspnoea, health status and psychological wellbeing. The main body of literature comes from COPD patients, as they provide the core evidence for PR programmes. PR is recommended even to severe patients having chronic respiratory failure; their significant psychological impairment and potential for greater instability during the PR programme will be carefully considered by the multidisciplinary team. Optimizing medical management (e g, inhaled bronchodilators, oxygen therapy, non- invasive ventilation) may enhance the results of exercise training. Patients who already receive long-term domiciliary non- invasive ventilation (NIV) for chronic respiratory failure might exercise with NIV during exercise training if acceptable and tolerable to the patient. It is not advisable to offer long-term domiciliary NIV with the only aim to improve outcomes during PR course. There are different attempts to use both negative and positive NIV in limited clinical studies. Long-term adherence to exercise is an important goal of PR programmes and teams, targeting to translate all-domain gains of PR into increased physical activity and participation to real life. Being a reliable alternative for the future, studies should focus on pressure regimens, type of devices, acceptability and portability for everyday activities.

Nowadays, peoples awareness of the role of diet in maintaining well-being and good health is increasing. Consumers expect that products will not only provide them with essential nutrients, but will also be a source of biologically active substances that are beneficial to their health. One of the "health trends" that has emerged among consumers around the world is kombucha with high antioxidant potential, obtained through the activity of a consortium of acetic acid bacteria and osmophilic yeast, also called "tea fungus". Kombucha is characterized by its health properties. Consumption of kombucha has always been associated with various health benefits. There are many personal experiences and feedback from kombucha drinkers around the world about the kombuchas ability to protect against a huge number of metabolic and infectious diseases. The promising results in in vitro and in vivo studies prompted us to create a new type of kombucha concentrat, which can be used directly for consumption, can be added to other drinks (juises, teas, herbal decoctions), might be used for preparation of carbonated and non-carbonated drinks, for food preservation, for vinegar preparation, as an additive in cosmetics and antiinflammatory products. The aim of this article is to review research in search of experimental confirmation of the many health aspects of kombucha. The analysis of the literature data is performed in accordance with the latest concepts of health protection requirements. Attention is paid to the active compounds in kombucha, responsible for the specific effect and the mechanisms of their action. It has been shown that kombucha can be effective in health prevention and recovery due to four main properties: detoxification, antioxidant, energizing potentials and stimulation of suppressed immunity. In recent years, its consumption has increased due to its useful properties and ingredients, immunostimulatory, anti-inflammatory, anti-tumor, antioxidant and other properties. Recent experimental studies of kombucha consumption suggest that the drink is suitable for prophylaxis against broad-spectrum metabolic and infectious disorders. This makes kombucha attractive as a drink for health prevention. In this article we describe the benefits of consuming the ancient traditional Chinese drink kombucha and describe the production of our new product using modern technology. Our combucha extract can be used for direct consumption and as a raw material for the production of various products containing kombucha. KOMBUCHA EXTRACT of DALVITA is made by a special technology and is 100 times more concentrated than kombucha tea, which makes its action a hundred times stronger and reduces the required daily amounts a hundred times.
