Domino-type Knoevenagel-Michael-hetero-Thorpe-Ziegler and Knoevenagel-hetero-Diels-Alder interactions using 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide and aliphatic aldehydes as initial compounds have been studied. These reactions have led to 2-amino-3-cyano-4H-pyran and 2H-3,4-dihydropyran derivatives, respectively. It has been shown that the three-component one-pot interaction of 1-ethyl-1H-2,1-benzothiazin-4(3H)one 2,2-dioxide with saturated aliphatic aldehydes and malononitrile proceeds under rather mild conditions and results in formation of 2-amino-6-ethyl-4-alkyl-4,6-dihydropyrano[3,2-c][2,1]benzothiazin-3-carbonitrile 5,5-dioxides with moderate and high yields. At the same time, the yields of target products decrease with the increase of the length of the aliphatic aldehyde carbon chain. In this regard, the use of citronellal allowed us to obtain the product of the three-component interaction with a low yield. To date, there is no information in the literature about the possible application of aliphatic dialdehydes in such three-component interactions. It has been found that the use of glutaric aldehyde results in the synthesis of a new class of bis-derivatives of 2-amino-4H-pyran, in which two fragments are linked by the polymethylene bridge. The use of Ξ±,Ξ²-unsaturated aldehydes in the three-component interaction with 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide and malononitrile was accompanied by decrease in the process efficiency compared to saturated aliphatic aldehydes. The target fused 2-amino-3-cyano-4H-pyran was obtained only when Ξ±-methylcinnamic aldehyde was used in the reaction. A two-component interaction of 1-ethyl-1H-2,1-benzothiazin-4(3H)-one 2,2-dioxide with citronellal has been also studied. It has been shown that this reaction is stereospecific. It proceeds through domino Knoevenagel-heteroDiels-Alder sequence resulting in a new heterocyclic system β 2,2a,3,4,5,6,6a,8-octahydroisochromeno[4,3-c] [2,1]benzothiazine 7,7-dioxide. The study of the antimicrobial activity of the compounds synthesized has allowed finding compounds with a moderate activity against P. aeruginosa Ρ C. albicans.ΠΠ·ΡΡΠ΅Π½Ρ Π΄ΠΎΠΌΠΈΠ½ΠΎ-Π²Π·Π°ΠΈΠΌΠΎΠ΄Π΅ΠΉΡΡΠ²ΠΈΡ ΠΠ½Π΅Π²Π΅Π½Π°Π³Π΅Π»Ρ-ΠΠΈΡ

Neurological syndromes and "red flags" indicating the cancer process
Neurological symptoms can be the first manifestations of the oncological process and make their debut earlier than the symptoms of a malignant disease. This article shows the" red flags" of neurology, which can become the first symptoms of oncological pathology, i.e., make their clinical debut earlier than the oncological process.ΠΠ΅Π²ΡΠΎΠ»ΠΎΠ³ΠΈΡΠ΅ΡΠΊΠΈΠ΅ ΡΠΈΠΌΠΏΡΠΎΠΌΡ ΠΌΠΎΠ³ΡΡ ΡΠ²Π»ΡΡΡΡΡ ΠΏΠ΅ΡΠ²ΡΠΌΠΈ ΠΏΡΠΎΡΠ²Π»Π΅Π½ΠΈΡΠΌΠΈ ΠΎΠ½ΠΊΠΎΠ»ΠΎΠ³ΠΈΡΠ΅ΡΠΊΠΎΠ³ΠΎ ΠΏΡΠΎΡΠ΅ΡΡΠ° ΠΈ Π΄Π΅Π±ΡΡΠΈΡΠΎΠ²Π°ΡΡ ΡΠ°Π½ΡΡΠ΅, ΡΠ΅ΠΌ ΡΠΈΠΌΠΏΡΠΎΠΌΡ Π·Π»ΠΎΠΊΠ°ΡΠ΅ΡΡΠ²Π΅Π½Π½ΠΎΠ³ΠΎ Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΡ.

Migraine and sleep disorders: a systematic review
Migraine and sleep disorders are common and often burdensome chronic conditions with a high prevalence in the general population, and with considerable socio-economic impact and costs. The existence of a relationship between migraine and sleep disorders has been recognized from centuries by clinicians and epidemiological studies. Nevertheless, the exact nature of this association, the underlying mechanisms and interactions are complex and not completely understood. Recent biochemical and functional imaging studies identified central nervous system structures and neurotransmitters involved in the pathophysiology of migraine and also important for the regulation of normal sleep architecture, suggesting a possible causative role, in the pathogenesis of both disorders, of a dysregulation in these common nervous system pathways. This systematic review summarizes the existing data on migraine and sleep disorders with the aim to evaluate the existence of a causal relationship and to assess the presence of influencing factors. The identification of specific sleep disorders associated with migraine should induce clinicians to systematically assess their presence in migraine patients and to adopt combined treatment strategies
Clinical features and results of surgical treatment of brain metastasis
Due to the increase in the frequency of metastatic brain lesions among other types of cancer, the urgency of a more thorough study of this problem is also increasing. This article describes the main sources of brain metastases, features of their metastasis, clinical manifestations and MRI images, as well as postoperative and long-term results of surgical treatment of patients with this pathology.Π ΡΠ²ΡΠ·ΠΈ Ρ ΡΠ²Π΅Π»ΠΈΡΠ΅Π½ΠΈΠ΅ΠΌ ΡΠ°ΡΡΠΎΡΡ ΠΌΠ΅ΡΠ°ΡΡΠ°ΡΠΈΡΠ΅ΡΠΊΠΈΡ

The representatives of the family Orchidaceae Juss. are often used as a source of natural antioxidants, including phenolic compounds, which play an important role in plant resistance under stressful conditions. This study investigates the content of lipid peroxidation products and soluble phenolic compounds in flowering plants of Platanthera bifolia (L.) Rich. growing in natural (forest park) and transformed (fly ash dumps of Thermal Power Stations) ecosystems of the Middle Urals, Russia, as well as the content of flavonoids at different stages of orchid development. Research has shown that in disturbed habitats, P. bifolia is capable of forming abundant populations containing a significant portion of the flowering plants. Additionally, flowering orchids from fly ash dumps contained an average 20 % more lipid peroxidation products, which indicated a shift in the redox balance towards oxidative processes. An increase by 2.4 times on average in the content of phenolic compounds, particularly flavonoids, was observed at all developmental stages of the plants growing in the transformed ecosystems. Regardless of the growing conditions, the non-flowering mature individuals were characterized by a minimum content of flavonoids, probably due to pre-generative metabolic restructuring. Yet, in the period of orchid blooming, the flavonoid content in their leaves increased again in all study sites. At the same time, the flavonoid proportion of the total soluble phenolic compounds was 42 % in the natural habitat, increasing to 66 % on average in the transformed ecosystems. Thus, flavonoids are involved in the protective adaptive responses of P. bifolia, not only ensuring the survival of this orchid but also contributing to the implementation of its ontogenetic program.

In-hospital stroke at patients of the hospital of the oncological profile
Between 6.5% and 15% of all strokes occur In patients already in hospital. At the same time, acute cerebrovascular accidents are the second most frequent complications of the central nervous system in patients with cancer pathology, behind only the metastatic lesions. This article raises the problem of one of the subtypes of stroke - occurred in a hospital β in-hospital stroke in patients with cancer hospital There are certificates in advantage that stroke occurs more frequently in cancer patients than in the average population. The aims of this review are to outline the magnitude of in-hospital stroke, risk factors, type of a stroke, feature of maintaining, the previous surgeries.Π‘ΠΎΠ³Π»Π°ΡΠ½ΠΎ Π΄Π°Π½Π½ΡΠΌ Π·Π°ΡΡΠ±Π΅ΠΆΠ½ΡΡ

Experimental Preventive Anti-Tularemia Preparation
Designed is an experimental preparation of a prototype chemical tularemia vaccine (PCTV). It is composed of protective antigenic complex (PAC) of tularemia microbe and S-layer protein (Slp) of plague microbe. Determined is optimum ratio of these components in the preparation and schedule of its administration. Displayed are the results of its testing as regards physical-chemical properties, reactogenicity, specific activity and impact on the immune system of laboratory animals. It is found out that preparation of the prototype is non-toxic for white mice and Guinea pigs and has no damaging effect on their immune systems. Single-stage subcutaneous immunization with PCTV induces elaboration of high-level adaptive immunity in laboratory animals within 14β21 days: specific antibody generation and stimulation of immune system cell component. PCTV protective index for white mice in case of experimental tularemia, caused by
Francisella tularensis subsp. holarctica, is 87,5 % on average; in case of infecting with
F. tularensis subsp. nearctica β 50 %; and high-level immunity in both cases. High potency of the experimental preparation against tularemia caused by subsp. holarctica (protective index is 75 %) and high-grade immunity persistence is verified on the model of Guinea pigs too
Controls on gut phosphatisation : the trilobites from the Weeks Formation LagerstΓ€tte (Cambrian; Utah)
Despite being internal organs, digestive structures are frequently preserved in Cambrian LagerstΓ€tten. However, the reasons for their fossilisation and their biological implications remain to be thoroughly explored. This is particularly true with arthropods--typically the most diverse fossilised organisms in Cambrian ecosystems--where digestive structures represent an as-yet underexploited alternative to appendage morphology for inferences on their biology. Here we describe the phosphatised digestive structures of three trilobite species from the Cambrian Weeks Formation LagerstΓ€tte (Utah). Their exquisite, three-dimensional preservation reveals unique details on trilobite internal anatomy, such as the position of the mouth and the absence of a differentiated crop. In addition, the presence of paired pygidial organs of an unknown function is reported for the first time. This exceptional material enables exploration of the relationships between gut phosphatisation and the biology of organisms. Indeed, soft-tissue preservation is unusual in these fossils as it is restricted to the digestive structures, which indicates that the gut played a central role in its own phosphatisation. We hypothesize that the gut provided a microenvironment where special conditions could develop and harboured a source of phosphorus. The fact that gut phosphatization has almost exclusively been observed in arthropods could be explained by their uncommon ability to store ions (including phosphorous) in their digestive tissues. However, in some specimens from the Weeks Formation, the phosphatisation extends to the entire digestive system, suggesting that trilobites might have had some biological particularities not observed in modern arthropods. We speculate that one of them might have been an increased capacity for ion storage in the gut tissues, related to the moulting of their heavily-mineralised carapace
