Determinants of the reproduction of Рrunus dulcis (Mill.) D.A.Webb. biotechnological methods
Authors: Shita О.
Published: May 2023

The purpose of the presented article is to establish the trophic and hormonal determinants of the ontogenesis of Prunus dulcis regenerants in vitro. One of the urgent problems in Ukraine is climate change, which reduces the level of achieving sustainable development and hinders humanity from both agroecological and food security. Such changes lead to the diversification of traditional agriculture. In Ukraine, almonds are a valuable, promising nut crop, thanks to which it is possible to diversify climate risks. Varieties of foreign selection with a long growing season and low winter hardiness are not suitable for our zone. Plants of four domestic varieties of almonds E5 Borozan, M41 Alex, Georgia, Louise (entered into the register in 2020) were involved in the study. One of the reliable methods for obtaining high-quality planting material, healthy from diseases, fast reproduction rates is microclonal reproduction. Therefore, modern nurseries switch to the production of planting material using biotechnological methods. Preparatory measures of mother plants of explant donors and decontamination increase the efficiency of work at the first stage of microclonal propagation. Primary explants are planted on media with a twice-reduced content of nutrients and a high content of cytokinins and gibberellins. Its success also depends on the selection of components, the pH of the nutrient medium (trophic determinants), and the interaction of exo-genous and endogenous hormones (hormonal determination.) The main trophic determinants are synthetic carbohydrates and mineral components added to artificial nutrient media. According to the Skoog-Miller rule, at the stage of multiplication, cytokinins predominate in the nutrient medium, and for root formation, their content decreases and the content of auxins decreases. Both auxins and cytokinins are added in high concentrations to stimulate callus formation. A systematic study of the features of the determinants of microclonal reproduction of almonds is relevant for the creation of MCR technologies. The lack or unavailability of one of the elements affects the plant object.
Key words: microclonal reproduction, almonds in vitro, power elements, synthetic phytohormones.

Secara tradisional, pembacaan meter energi dilakukan oleh operator manusia yang bergerak dari rumah ke rumah untuk mengumpulkan bacaan. Latihan ini membutuhkan tenaga operator yang sangat banyak dan banyak waktu untuk mencapai pembacaan meter yang lengkap di area tertentu. Makalah ini berusaha untuk menghilangkan masalah ini dengan menggunakan sistem telemetering. Dengan sistem ini, daya dapat diukur dari jarak jauh. Untuk mencapai hal ini, pembacaan dari pengukur energi di lokasi diproses oleh perangkat mikrokontroler yang kemudian mengirimkan informasi konsumsi energi ke modul Global System Mobile (GSM). Modul GSM kemudian mengirimkan informasi ini menggunakan gelombang mikro ke pelanggan seluler tertentu yang menerimanya dalam bentuk Layanan Pesan Singkat (SMS). Pembacaan juga ditransmisikan ke sistem telemetering berbasis web melalui server. Di situs jarak jauh, komputer jarak jauh yang dapat mengakses internet dapat memperoleh data dari server melalui internet. Mikrokontroler dikembangkan sedemikian rupa sehingga mencapai komunikasi antara meteran energi dan server tertentu menggunakan protokol Transmission Control Protocol (TCP). Program perangkat lunak juga dikembangkan untuk memfasilitasi transfer data ke pengguna di situs jarak jauh. Dengan sistem telemetering berbasis web yang terkoneksi dengan internet, pengukuran energi listrik dapat diakses secara global. Efisiensi saluran transmisi penting untuk keberhasilan sistem telemetering berbasis SMS dan web.

Ayam pedaging merupakan bisnis usaha yang menjanjikan, tetapi ada berbagai permasalahan terkait dengan kebersihan kandang yang ditimbulkan oleh kotoran ayam dan bau amonia. Bahaya yang ditimbulkan antara lain produktivitas dan pertumbuhan ayam menjadi lambat. Oleh karena itu, dari permasalahan tersebut diperlukan sebuah sistem monitoring pengendalian gas amonia serta pembersihan kotoran secara otomatis. Sensor MQ135 digunakan untuk mengetahui kadar gas amonia dan DHT11 untuk membaca suhu kandang. Jika sensor MQ-135 membaca nilai konsentrasi gas amonia (>=20ppm) maka akan menghidupkan kipas dc selama beberapa detik sampai nilai amonia dibawah 20 ppm, jika gas amonia melebihi atau sama dengan 30ppm maka akan menghidupkan kipas dc dan menghidupkan pompa air sebagai pembersihan kotoran pada kandang selama beberapa detik sampai kotoran bersih. Blynk sebagai monitoring yang menampilkan hasil pembacaan dari sensor MQ-135 dan DHT11 di handphone, dan juga hasil dari pembacaan sensor-sensor akan tersimpan google sheet. Hasil dari penelitian ini menunjukkan bahwa prototipe kandang pintar berhasil memonitor kadar amonia di dalam kandang dan membersihkan kotoran secara otomatis. Sensor amonia berhasil mendeteksi kadar amonia yang tinggi dan memberikan notifikasi pada pengguna. Sistem pembersih kotoran otomatis berhasil membersihkan kotoran secara otomatis. Alat ini dapat membantu peternak meningkatkan kesehatan dan kenyamanan anak ayam secara efektif dan efisien.

Background

COVID-19 has affected many people globally, including in Bangladesh. Due to a lack of preparedness and resources, Bangladesh has experienced a catastrophic health crisis, and the devastation caused by this deadly virus has not yet been halted. Hence, precise and rapid diagnostics and infection tracing are essential for managing the condition and limiting its spread. The conventional screening procedure, such as reverse transcription polymerase chain reaction (RT-PCR), is not available in most rural areas and is time-consuming. Therefore, a data-driven intelligent surveillance system can be advantageous for rapid COVID-19 screening and risk estimation.

Objectives

This study describes the design, development, implementation, and characteristics of a nationwide web-based surveillance system for educating, screening, and tracking COVID-19 at the community level in Bangladesh.

Methods

The system consists of a mobile phone application and a cloud server. The data is collected by community health professionals via home visits or telephone calls and analyzed using rule-based artificial intelligence (AI). Depending on the results of the screening procedure, a further decision is made regarding the patient. This digital surveillance system in Bangladesh provides a platform to support government and non-government organizations, including health workers and healthcare facilities, in identifying patients at risk of COVID-19. It refers people to the nearest government healthcare facility, collecting and testing samples, tracking and tracing positive cases, following up with patients, and documenting patient outcomes.

Results

This study began in April 2020, and the results are provided in this paper till December 2022. The system has successfully completed 1,980,323 screenings. Our rule-based AI model categorized them into five separate risk groups based on the acquired patient information. According to the data, around 51% of the overall screened populations are safe, 35% are low risk, 9% are high risk, 4% are mid risk, and the remaining 1% is very high risk. The dashboard integrates all collected data from around the nation onto a single platform.

Conclusion

This screening can help the symptomatic patient take immediate action, such as isolation or hospitalization, depending on the severity. This surveillance system can also be utilized for risk mapping, planning, and allocating health resources to more vulnerable areas to reduce the virus's severity.

Published: May 2023

Background: Acute lung injury (ALI) is a common clinical disease with high mortality. Rujin Jiedu powder (RJJD) has been clinically utilized for the treatment of ALI in China, but the active constituents in RJJD and its protective mechanisms against ALI are still unclear.

Methodology: ALI mice were established by intraperitoneal injection of LPS to test the effectiveness of RJJD in treating ALI. Histopathologic analysis was used to assess the extent of lung injury. An MPO (myeloperoxidase) activity assay was used to evaluate neutrophil infiltration. Network pharmacology was used to explore the potential targets of RJJD against ALI. Immunohistochemistry and TUNEL staining were performed to detect apoptotic cells in lung tissues. RAW264.7 and BEAS-2B cells were used to explore the protective mechanisms of RJJD and its components on ALI in vitro. The inflammatory factors (TNF-α, IL-6, IL-1β and IL-18) in serum, BALF and cell supernatant were assayed using ELISA. Western blotting was performed to detect apoptosis-related markers in lung tissues and BEAS-2B cells.

Results: RJJD ameliorated pathological injury and neutrophil infiltration in the lungs of ALI mice and decreased the levels of inflammatory factors in serum and BALF. Network pharmacology investigations suggested that RJJD treated ALI via regulating apoptotic signaling pathways, with AKT1 and CASP3 as crucial targets and PI3K-AKT signaling as the main pathway. Meanwhile, baicalein, daidzein, quercetin and luteolin were identified as key constituents in RJJD targeting on the above crucial targets. Experimental investigations showed that RJJD significantly upregulated the expression of p-PI3K, p-Akt and Bcl-2, downregulated the expression of Bax, caspase-3 and caspase-9 in ALI mice, and attenuated lung tissue apoptosis. Four active constituents in RJJD (baicalein, daidzein, quercetin and luteolin) inhibited the secretion of TNF-α and IL-6 in LPS-induced RAW264.7 cells. Among these components, daidzein and luteolin activated the PI3K-AKT pathway and downregulated the expression of apoptosis-related markers induced by LPS in BEAS-2B cells.

Conclusion: RJJD alleviates the inflammatory storm and prevents apoptosis in the lungs of ALI mice. The mechanism of RJJD in treating ALI is related to the activation of PI3K-AKT signaling pathway. This study provides a scientific basis for the clinical application of RJJD.
Unraveling the celiac disease-related immunogenic complexes in a set of wheat and tritordeum genotypes: implications for low-gluten precision breeding in cereal crops

Published: May 2023

The development of low-gluten immunogenic cereal varieties is a suitable way to fight the increment of pathologies associated with the consumption of cereals. Although RNAi and CRISPR/Cas technologies were effective in providing low-gluten wheat, the regulatory framework, particularly in the European Union, is an obstacle to the short- or medium-term implementation of such lines. In the present work, we carried out a high throughput amplicon sequencing of two highly immunogenic complexes of wheat gliadins in a set of bread and durum wheat, and tritordeum genotypes. Bread wheat genotypes harboring the 1BL/1RS translocation were included in the analysis and their amplicons successfully identified. The number of CD epitopes and their abundances were determined in the alpha- and gamma-gliadin amplicons, including 40k-γ-secalin ones. Bread wheat genotypes not containing the 1BL/1RS translocation showed a higher average number of both alpha- and gamma-gliadin epitopes than those containing such translocation. Interestingly, alpha-gliadin amplicons not containing CD epitopes accounted for the highest abundance (around 53%), and the alpha- and gamma-gliadin amplicons with the highest number of epitopes were present in the D-subgenome. The durum wheat and tritordeum genotypes showed the lowest number of alpha- and gamma-gliadin CD epitopes. Our results allow progress in unraveling the immunogenic complexes of alpha- and gamma-gliadins and can contribute to the development of low-immunogenic varieties within precision breeding programs, by crossing or by CRISPR/Cas gene editing.

We describe the PACE-MAPP algorithm that simultaneously retrieves aerosol and ocean optical parameters using multiangle and multispectral polarimeter measurements from the SPEXone, Hyper-Angular Rainbow Polarimeter 2 (HARP2), and Ocean Color Instrument (OCI) instruments onboard the NASA Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) observing system. PACE-MAPP is adapted from the Research Scanning Polarimeter (RSP) Microphysical Aerosol Properties from Polarimetry (RSP-MAPP) algorithm. The PACE-MAPP algorithm uses a coupled vector radiative transfer model such that the atmosphere and ocean are always considered together as one system. Consequently, this physically consistent treatment of the system across the ultraviolet, (UV: 300–400 nm), visible (VIS: 400–700 nm), near-infrared (NIR: 700–1100 nm), and shortwave infrared (SWIR: 1100–2400 nm) spectral bands ensures that negative water-leaving radiances do not occur. PACE-MAPP uses optimal estimation to simultaneously characterize the optical and microphysical properties of the atmosphere’s aerosol and ocean constituents, find the optimal solution, and evaluate the uncertainties of each parameter. This coupled approach, together with multiangle, multispectral polarimeter measurements, enables retrievals of aerosol and water properties across the Earth’s oceans. The PACE-MAPP algorithm provides aerosol and ocean products for both the open ocean and coastal areas and is designed to be accurate, modular, and efficient by using fast neural networks that replace the time-consuming vector radiative transfer calculations in the forward model. We provide an overview of the PACE-MAPP framework and quantify its expected retrieval performance on simulated PACE-like data using a bimodal aerosol model for observations of fine-mode absorbing aerosols and coarse-mode sea salt particles. We also quantify its performance for observations over the ocean of dust-laden scenes using a trimodal aerosol model that incorporates non-spherical coarse-mode dust particles. Lastly, PACE-MAPP’s modular capabilities are described, and we discuss plans to implement a new ocean bio-optical model that uses a mixture of coated and uncoated particles, as well as a thin cirrus model for detecting and correcting for sub-visual ice clouds.

Published: May 2023

The parallel connection of technical and biological systems with a comparable mechanical behavior offers the possibility of reducing the interaction forces between those systems. Especially in the context of human–robot interaction (e.g., exoskeletons), it can improve user safety and acceptance at the same time. With this aim, we used antagonistic actuators with nonlinear compliance for a modular upper-extremity exoskeleton following biological paragons, mirroring the “blueprint” of its human user. In a test-bed setup, we compared antagonistic compliant actuation with antagonistic stiff, unilateral stiff and unilateral compliant actuation in the artificial “elbow joint” of the exoskeleton test bed. We show that this type of actuation allows the variation of the joint stiffness during motion, independent of the position. With the approach we propose, compliance leads to reduced force peaks and angular jerk, without sacrifices in terms of time constants and overshoot of amplitudes. We conclude that the presented actuation principle has considerable benefits in comparison to other types of exoskeleton actuation, even when using only commercially available and 3D printed components. Based on our work, further investigations into the control of compliant antagonistically actuated exoskeletons become realizable.
