The progress of science and technology significantly depends on the success in creating new materials. Composite materials are a heterogeneous structure formed by a combination of reinforcing elements and isotropic binder (binder) material, currently widely used in various fields of technology. but for the economy is more important mass application. For this purpose, more thorough and long-term research and experimental implementations are carried out, which require significant intellectual and material costs. Development of structural elements using basalt fiber began in NDIBV since 1987. and experimental samples of prestressed concrete structures with basalt-plastic reinforcement. Research to identify the interaction of cement with basalt fiber and the design of effective concrete structures using basalt reinforcement. Concrete beams with basalt reinforcement were successfully tested. Unfortunately, the results of research have not been widely implemented. Therefore, this article is devoted to the problems of mass introduction into construction practice of various types of composite materials, including basalt reinforcement. The advantages and disadvantages of composite reinforcement in comparison with steel are discussed. During the theoretical and experimental studies, both positive and negative aspects of the use of basalt reinforcement were identified. So experiments have shown that basalt fiber loses strength in the environment of Portland cement stone. But this shortcoming has been overcome by the efforts of scientists, it is important to use certain defects of basalt fibers for specific conditions. There are the following main types of basalt fibers:
1) basalt continuous fibers with a diameter of 8 - 11 microns, 12 - 14 microns, 16 - 20 microns with a fiber length of 25 - 50 mm and more;
2) staple short fibers with a diameter of 6 - 12 microns and a length of 5 - 10 mm and several diameters;
3) basalt superthin fibers with a diameter of 0.5 - 1 microns with a length of 10 - 50 mm;
4) coarse basalt fibers with a diameter of 100 - 400 microns.
To create structures with certain properties for specific conditions, appropriate basalt fibers are selected. According to the research results, recommendations and normative documents have been developed. Suggestions for measures to improve and successfully widely use composite elements for reinforcement of concrete structures.

The constant growth of the urban population has led to a number of serious social, economic and environmental problems. Due to the density of urban development, there is almost no space left for greenery, parks, squares. Not only urban recreational areas are being reduced, but also suburban green areas, which act as green urban belts. Such green belts are a source of oxygen, a zone of conservation of biodiversity of phyto- and zoocenoses, migration routes for biota from the urban environment to the natural and vice versa. In addition, they maintain the climate balance of the urban system, protecting it from wind, temperature changes, flooding, landslides and floods.
Currently, the urban system spreads horizontally and vertically, which dramatically reduces the attractiveness of the landscape. The situation is complicated by economic reasons: the cost of land in the city center is very high. Therefore, it is more profitable to give it for construction, rather than creating recreation areas. Due to the lack of green areas in the central areas, there is an effect of "heat island" of urban centers, when the temperature difference between the central urban and suburban areas is about 4… 7 ° C.
Factors that change the microclimate of urban coenoses also include: air pollution (change in its composition, which is expressed in an increase in the content of solid suspended particles and gaseous impurities); change in heat transfer due to the closed horizon, thermophysical properties of urban surfaces (heat capacity, reflectivity of impurities); artificial formation of heat flows during heating, operation of vehicles, at industrial enterprises. Economic and environmental problems of cities lead to social ones, when the level of chronic diseases increases, the psycho-emotional state of a person deteriorates, and the birth rate decreases. Therefore, modern cities need to use modern energy-efficient technologies on roofs - "green structures", conservatories and greenhouses, which are able to solve environmental, economic and social problems.

Published: July 2022

Background: Use of telephone, video and e-consultations is increasing. These can make consultations more transactional, potentially missing patients’ concerns. This study aimed to develop a complex intervention to address patients’ concerns more comprehensively in general practice and test the feasibility of this in a cluster-randomised framework. The complex intervention used two technologies: a patient-completed pre-consultation form used at consultation opening and a doctor-provided summary report provided at consultation closure. This paper reports on the development and realist evaluation of the pre-consultation questionnaire. Methods: A person-based approach was used to develop the pre-consultation form. An online questionnaire system was designed to allow patient self-completion of a form which could be shared with GPs. This was tested with 45 patients in three rounds, with iterative adjustments made based on feedback after each round. Subsequently, an intervention incorporating the pre-consultation form with the summary report was then tested in a cluster-randomised framework with 30 patients per practice in six practices: four randomised to intervention, and two to control. An embedded realist evaluation was carried out. The main feasibility study results are reported elsewhere. Results: Intervention Development: 15 patients were recruited per practice. Twelve patients, six GPs and three administrators were interviewed and 32 changes were made iteratively in three rounds. Recruitment rates (proportion of patients responding to the text) increased from 15% in round one to 50% in round three. Realist evaluation: The pre-consultation form was most useful for people comfortable with technology and with hidden concerns or anxiety about the consultation. It resulted in more issues being discussed and support provided, more effective use of time and greater patient satisfaction. Conclusions: The person-based approach was successful. The pre-consultation form uncovers more depth and improves satisfaction in certain consultations and patients. Technological improvements are required before this could be rolled out more widely.

Published: July 2022

N6-methyladenosine (m6A) methylation, one of the most crucial RNA modifications, has been proven to play a key role that affect prognosis of soft tissue sarcoma (STS). However, m6A methylation potential role in STS metabolic processes remains unknown. We comprehensively estimated the m6A metabolic molecular subtypes and corresponding survival, immunity, genomic and stemness characteristics based on 568 STS samples and m6A related metabolic pathways. Then, to quantify the m6A metabolic subtypes, machine learning algorithms were used to develop the m6A-metabolic Scores of individual patients. Finally, two distinct m6A metabolic subtypes (Cluster A and Cluster B) among the STS patients were identified. Compared to Cluster B subtype, the Cluster A subtype was mainly characterized by better survival advantages, activated anti-tumor immune microenvironment, lower gene mutation frequency and higher anti-PD-1 immunotherapy response rates. We also found that the m6A-metabolic Scores could accurately predict the molecular subtype of STS, prognosis, the abundance of immune cell infiltration, tumor metastasis status, sensitivity to chemotherapeutics and immunotherapy response. In general, this study revealed that m6A-regulated tumor metabolism processes played a key role in terms of prognosis of STS, tumor progression, and immune microenvironment. The identification of metabolic molecular subtypes and the construction of m6A-metabolic Score will help to more effectively guide immunotherapy, metabolic therapy and chemotherapy in STS.
Early increase of cerebrospinal fluid 14-3-3ζ protein in the alzheimer's disease continuum
Authors: Lu Yuanyuan 
Published: July 2022

BackgroundThe earlier research has shown that the 14-3-3ζ is increased in neurofibrillary tangles (NFTs) of human Alzheimer's disease (AD) brains and stimulates the tau phosphorylation. Cerebrospinal fluid (CSF) 14-3-3ζ along the AD continuum remains to be explored.MethodsWe analyzed 113 cognitive normal (CN) controls, 372 patients with mild cognitive impairment (MCI), and 225 patients with AD dementia from the Alzheimer's Disease Neuroimaging Initiative database. CSF 14-3-3ζ protein was measured by Mass Spectrometry.ResultsWe observed higher CSF 14-3-3ζ in the MCI group vs. the CN group and in the AD group vs. the MCI or CN group. The 14-3-3ζ was able to distinguish AD from CN and MCI. High 14-3-3ζ predicted conversion from MCI to AD. In CSF, phosphorylated tau at threonine 181 and total-tau were associated with 14-3-3ζ in MCI and AD groups, and beta-amyloid (Aβ) 42 correlated with 14-3-3ζ in the MCI group. Baseline high 14-3-3ζ was associated with cognitive decline, brain atrophy, glucose hypometabolism, and Aβ deposition in MCI and AD at baseline and follow-up.ConclusionOur findings revealed the potential diagnostic and prognostic utility of CSF 14-3-3ζ in the AD continuum. The 14-3-3ζ could be a promising therapeutic target for the intervention of AD.

Published: July 2022

ObjectivesDementia with Lewy bodies (DLB) is the second most common type of neurodegenerative dementia following Alzheimer's disease dementia (ADD). This study investigated the diagnostic role of the gesture imitation test in detecting DLB and differentiating DLB from ADD.MethodsA total of 63 patients with DLB, 93 patients with ADD, and 88 healthy controls were included in this study. All participants were administered the gesture imitation test, the Mini-Mental State Examination (MMSE), the Montreal Cognitive Assessment (MoCA), the clock drawing test (CDT), and other neuropsychological tests.ResultsThe patients with DLB performed worse than the healthy controls in the global scores and on every item of the gesture imitation test (p &lt; 0.001). The area under the curve (AUC) for the global scores was 0.889 (p &lt; 0.001) in differentiating the DLB and control groups. Item 4 was a better discriminator, with a sensitivity of 79.37% and a specificity of 79.55%. The AUC for the global scores decreased to 0.593 and the difference was marginal (p = 0.079) in differentiating the DLB and ADD groups. The patients with DLB performed worse on Items 1 and 4 compared with the patients with ADD (p = 0.040, 0.004). The gesture imitation test was positively correlated with the scores of the MMSE (r = 0.355, p = 0.017), the MoCA (r = 0.382, p = 0.010), and the CDT (r = 0.407, p = 0.005) in patients with DLB.ConclusionThe gesture imitation test is an easy, rapid tool for detecting DLB and has a role in differentiating DLB from ADD, especially in Items 1 and 4.

ObjectiveWe wished to explore Parkinson's disease (PD) subtypes by clustering analysis based on the multimodal magnetic resonance imaging (MRI) indices amplitude of low-frequency fluctuation (ALFF) and gray matter volume (GMV). Then, we analyzed the differences between PD subtypes.MethodsEighty-six PD patients and 44 healthy controls (HCs) were recruited. We extracted ALFF and GMV according to the Anatomical Automatic Labeling (AAL) partition using Data Processing and Analysis for Brain Imaging (DPABI) software. The Ward linkage method was used for hierarchical clustering analysis. DPABI was employed to compare differences in ALFF and GMV between groups.ResultsTwo subtypes of PD were identified. The “diffuse malignant subtype” was characterized by reduced ALFF in the visual-related cortex and extensive reduction of GMV with severe impairment in motor function and cognitive function. The “mild subtype” was characterized by increased ALFF in the frontal lobe, temporal lobe, and sensorimotor cortex, and a slight decrease in GMV with mild impairment of motor function and cognitive function.ConclusionHierarchical clustering analysis based on multimodal MRI indices could be employed to identify two PD subtypes. These two PD subtypes showed different neurodegenerative patterns upon imaging.

Authors: Yang Zhen , Shi Guangjun 
Published: July 2022

BackgroundIntraductal papillary mucinous neoplasm (IPMN) and mucinous cystic neoplasm (MCN) are two main histological subtypes of pancreatic cystic neoplasms with rapidly increasing incidence recently. The natural histories, treatment patterns, and survival outcomes of invasive IPMN and invasive MCN have not been well explored.MethodsPatients with a diagnosis of invasive IPMN and invasive MCN in the SEER database from 2000 through 2018 were retrospectively identified. Multivariable Cox regression analysis was conducted to determine the independent risk factors associated with overall survival (OS). Subgroup analyses of survival outcomes for invasive IPMN and invasive MCN were conducted. The OS for invasive IPMN was compared between patients who underwent surgery alone and those who received surgery plus chemotherapy by propensity score matching (PSM).ResultsA total of 2,505 patients were included, of whom 2,300 were diagnosed with invasive IPMN and 205 were diagnosed with invasive MCN. Half of the invasive IPMN (48.4%) and three-quarters of the invasive MCN (76.1%) patients were female. Of all patients, both the OS and cancer-specific survival were significantly better in the invasive MCN cohort compared to the invasive IPMN cohort. In subgroup analyses, while invasive MCN experienced better OS compared to invasive IPMN in the subgroups of patients with local–regional disease, the survival advantages disappeared in patients at a distant stage. In addition, surgery plus chemotherapy in invasive IPMN patients was associated with significantly better survival compared to surgery alone after PSM.ConclusionWe examined the demographic and clinical characteristics between invasive IPMN and invasive MCN patients using a large-population-based analysis. Although the OS is significantly better for invasive MCN versus invasive IPMN, the difference disappeared in patients with distant disease. A combination of surgery and chemotherapy in selected invasive IPMN patients could confer survival benefits compared to surgery alone.
