Esthetic And Functional Integration Of Soft Tissue Around Dental Implants: Thickness, Width, Stability.

The long-term Functional success of the implant treatment depends on the stability of the crestal bone tissue around the implant platform. The Esthetic result is achieved by an adequate soft tissue in the peri-implant zone. Furthermore, the soft tissue creates the buffer area that ensures the mechanical and biological protection of the underlying bone. Therefore, it is necessary to maintain for a long term, not only the implant osseointegration but also the integration of the soft tissue around the Sub and Supra-structure of the restoration. In order to create the protective soft tissue area, it is necessary to ensure three criteria. This treatment approach will be defined as the TWS – Soft Tissue Management : T for Thickness , W for Width, and S for Stability . The purpose of this article is to present with clinical cases, the detailed description of each criteria. There are many ways to achieve the two first criteria and they are well described in the literature. Achieving the third criteria of the Stability become possible only in the last years since the development of the digital technology and its implementation into the dental practice. A one time abutment and the creation of peri- implant mucosal thickness with an optimal amount of the attached keratinized gingiva above and around the implant platform, for muco-gingival integration of the system, are therefore a prerequisite for functional and esthetic result. The article presents the possibility for the clinicians to use in their daily practice this new clinical approach of TWS - Soft Tissue Management.

Influence of a complex of agrotechnical methods on yield qualities of F1 seeds of the hybrid Fakel in progeny (report II)

The researches were conducted on fields of a farm “Berezanskoe”, Korenovsk district, Krasnodar region. Size of a plot is equal to 112 sq. м, in three replications. The object of the research was F1 seeds of interlinear sunflower hybrid Fakel produced in 2020 with different positive modifications on a hybridization plot. The seed were planted in 2021 to estimate impact of the positive modifications (methods) on yield and quality seeds of the hybrid Fakel in progeny. Two sowing rates (60 and 80 thousand per a га) were used to realize fully a yield potential of the hybrid. A certain positive impact was fixed in variants with application of biological protection measures and microbiological fertilizers during plants vegetative period. Yield increase was 0.02 t per ha. Increase of oil content and oil yield of the hybrids Fakel in progeny under different positive modifications was insignificant: 0.2–0.3% and 0.01–0.02 t per ha, respectively. Application of biological protection measures and microbiological fertilizer during the vegetative period of plants on the hybridization in 2020 contributed in a profitability increase by 6% when sowing F1 seed in 2021 with sowing rate of 80 thousand seed per ha.

Commercial immunoassays for detection of anti-SARS-CoV-2 spike and RBD antibodies: urgent call for validation against new and highly mutated variants

Measuring the level of protection conferred by anti-SARS-CoV-2 (trimeric) spike or RBD (receptor binding domain) antibodies (especially total and IgG) is a suitable and reliable approach for predicting biological protection against the risk of infection and severe coronavirus disease 2019 (COVID-19) illness. Nonetheless, SARS-CoV-2 has undergone a broad process of recombination since the identification of the prototype lineage in 2019, introducing a huge number of mutations in its genome and generating a vast array of variants of interest (VoI) and concern (VoC). Many of such variants developed several mutations in spike protein and RBD, with the new Omicron (B.1.1.529) clade displaying over 30 changes, 15 of which concentrated in the RBD. Besides their impact on virus biology, as well as on the risk of detection failure with some molecular techniques (i.e., S gene dropout), recent evidence suggests that these mutations may also jeopardize the reliability of currently available commercial immunoassays for detecting anti-SARS-CoV-2 antibodies. The antigen (either spike or RBD) and epitopes of the prototype SARS-CoV-2 coated in some immunoassays may no longer reflect the sequence of circulating variants. On the other hand, anti-SARS-CoV-2 antibodies elicited by highly mutated SARS-CoV-2 variants may no longer be efficiently recognized by the currently available commercial immunoassays. Therefore, beside the compelling need to regularly re-evaluate and revalidate all commercially available immunoassays against live virus neutralization assays based on emerging VoCs or VoIs, diagnostic companies may also consider to redevelop their methods, replacing former SARS-CoV-2 antigens and epitopes with those of the new variants.

To understanding the effects of conditioning thinking: about new book of Terrence Webster-Doyle

Review of the book Mind Games: towards understanding the nature of prejudice and conflict, or how to learn to live in peace by Terrence Webster-Doyle. Mind Games: To understand the roots of prejudice and how to learn live peacefully: a scientific and educational publication. T. Webster-Doyle. Samara Cultural Society Artifact-Cultural Diversity. Samara: Samara Scientific Center of the Russian Academy of Sciences; 2020. 55 p. Reviewer considers that T. Webster-Doyles book is a brilliant example of how conflicts can be resolved most effectively without theorized distraction. T. Webster-Doyles book is small in volume, but very significant in content. The author offers a real program for taming the conflicts and violence that fill the entire human history. Until now, there is a clear lack of research on the universal determinants of the emergence and dynamics of conflict. A paradoxical situation arises when methods of conflict resolution are studied and modified, despite the fact that its initial determinants are not accurately determined. The models of taming conflicts that are being replicated in the social sciences almost do not solve the very problem of overcoming violence in society. Note that T. Webster-Doyle defines her book as the most significant work of her life. The author proposes an original approach to the determination of the conflict and defines the ways of its resolution in direct relationship with the understanding of its determinants. Also, the advantage of the book is a good literary presentation of the material. T. Webster-Doyle views conflict as a phenomenon created by the human mind, which at the same time, in a paradox, is trying to solve a problem which it itself creates. This work is devoted to the study of the determinants of conflict, which are considered comprehensively in the relationship of biological and social determinants: as generated by genetically programmed brain programs and at the same time as a function of peoples perception of the world around them and each other. The author notes that the universal basis of biological programming is the general motivation the desire to survive. Consequently, this work presents a program for resolving the conflict based on a comprehensive consideration of the conflict as a sociobiological phenomenon, which is based on the conditioned thinking of a person (primordial biological protection of his brain). The advantage of the book is its versatility. The author does not just consider the problem of the conflict, its components, the parties to the conflict, conflict genes, the incident, etc. He is looking for an approach that allows you to take a fresh look at this problem and find ways to prevent and destroy the conflict.

Effectiveness of biological protection of cabbage against pests in the conditions of the Primorsky Territory

The results of the use of entomophages and biological products to regulate the number of cabbage pests (cabbage moth Mamestra brassicae L., cabbage butterfly Pieris brassicae L., turnip butterfly Pieris rapae L., diamondback moth Plutella xylostella L.) are presented. The study was carried out in the Primorsky Territory in 2018-2020. The efficiency of Trichogramma ussuricum Sorokina applications was assessed on cabbage varieties. The effectiveness of the entomophage against the cabbage moth varied from 33.3 to 66.6%, against the turnip butterfly - from 32.6 to 70.2%. In field experiments the effectiveness of biological products Fitoverm EC (0.09 l/ha), Akarin EC (1.6 l/ha), Proclaim WG (0.3 kg/ha), Bitoxibacillin (10 l/ha), Bitoxibacillin P (2 kg/ha), Lepidocid SC (2 l/ha), Lepidocid P (2 kg/ha) against diamondback moth are studied. Cabbage plants were sprayed with the preparations once. Pest counts were carried out before treatment and after treatment on the 5th, 10th and 15th day in accordance with the approved methods. Bioinsecticide Proclaim showed a high efficiency of 93.0-100% on the 5-10th day. The effectiveness of preparations based on aversectin C and avertin N was 65.0-88.6%. Using the biological product Bitoxibacillin and Lepidocid a decrease the number of diamondback moth relative to the control by 61.2-97.5 и 65.0-78.0% was registered.

New Insights Into Biopesticides: Solid and Liquid Formulations of Essential Oils and Derivatives

Essential oils and derivatives have shown effective insecticidal activity against different agricultural pests. However, the use of these bioactive compounds can result in negative effects due to their high volatility and difficult handling. Both solid and liquid formulations of essential oils have been developed in recent years. Currently, there are some commercial products available in the market, but they are still scarce and mainly based on liquid formulations. Solid formulations developed through spray-drying, including complex or micro/nanospheres, present differences in encapsulation efficiency, particle size, and controlled release, depending mainly on the wall material or surfactant content. Spray-dried essential oils have clear advantages over liquid formulations in terms of biological protection and storage. However, liquid formulations are usually easier scaled and applied. This review focuses on the advances of essential oils in both solid and liquid formulations (focusing on nanoemulsions) and derivatives to allow for their proper use in agriculture.

All-inorganic perovskite quantum dots-based electrospun polyacrylonitrile fiber for ultra-sensitive trace-recording

All-inorganic dual-phase CsPbBr3-Cs4PbBr6 quantum dots (CPB QDs)-based polyacrylonitrile (PAN) fiber synthesized by supersaturated recrystallization and electrospinning technique possesses characteristics of homogeneous morphology, high crystallinity and solution sensitivity. Under 365 nm laser excitation, CPB@PAN fiber exhibits surprising trace-recording capability attributing to the splash-enhanced fluorescence (FL) performance with a narrow-band emission at 477-515 nm. In the process of ethanol-anhydrous (EA) and water splashing, the CPB@PAN fiber presents conspicuous blue and green emission when contacting with EA and water, and maintains intense blue and green FL for more than 4 months. These experimental and theoretical findings provide a facile technology for the development of biological protection display, biotic detection and moisture-proof forewarning based on the trace-recording performance of CPB@PAN fiber.

Arboreal Fungi in Biological Control against Soil Fungi

Fungi are important components of every ecosystem. In nature, they play a significant role as decomposers, decomposing organic matter into simple compounds available for plants. They are a curious group of organisms that attracts more and more interest not only among mycologists and phytopathologists, but also geneticists, biochemists and physiologists. Metabolic products of arboreal fungi show multidirectional action, including in the field of biological protection against harmful phytopathogens. Particularly invasive and difficult to control are soil fungi, phytobacteria and phytoviruses, which are widely spread in the rhizosphere. Moreover, the variety of pathogens is constantly increasing, and new forms are rapidly emerging, often more resistant to the biological control agents used so far.
