Standardization of Various Chemical Seed Priming on Seed Quality Parameters in Black Gram (Vigna mungo)

Black gram is an important pulse crop in India. It is a major source of dietary protein for the poor people and provides nutritional security. It is mostly grown by the small and marginal farmers under resource constraints situation particularly in rainfed and rice fallow conditions. Seed priming is one such effective technology to achieve high growth, vigor, better stand establishment. The current study aimed to study the standardization of various chemical on crop growth in black gram. A laboratory experiment was conducted in Factorial Completely Randomized Design (FCRD) with three replications using various concentrations (1%, 2%, 3% and 4 %) as first factor and different durations (4 and 6 h) of priming as second factor and different chemicals such as ZnSO4, MnCl2, MgSO4, CaCl2, KCl and KNO3 as third factor. Seeds were primed with different chemicals in different concentrations and in different duration evaluated for its quality parameters to find out suitable seed priming technique. Among all treatments seed priming with ZnSO4 1% for 6 hours recorded higher germination (98%), longest root length (22.17 cm), shoot length (19.15 cm), higher seedling dry matter production (0.93 g seedlings-10), fresh weight (8.93 g seedlings-10) and vigor index (4004) than control under laboratory experiment. The results indicate that use of ZnSO4 1% for 6 hours enhances the seed performance regarding seed quality characters.

Chemical Composition and In Vitro Protein Digestibility of Duckweed and Feed Ingredients

Duckweed is an aquatic floating plant with the potential to be used as animal feed due to its richness in protein, amino acids, starch, vitamin and minerals. Furthermore, duckweed has a high growth rate and reproducibility. Therefore, this research aimed to determine the chemical composition and in vitro protein digestibility of duckweed (Lemna, Wolffia and Spirodela) in comparison to other feed ingredients. The chemical composition was determined through proximate analysis including dry matter (DM), crude protein (CP), ether extract (EE), crude fiber (CF), ash and nitrogen free extract. The in vitro protein digestibility procedure simulates conditions similar to those in the swine digestive tract using synthetic enzymes to control pH, temperature and digestion time. In the results of chemical composition, Lemna and Wolffia were classified as protein sources, with high CP content (221.87 and 442.65 g/kg DM, respectively) and low CF content (63.30 and 109.11 g/kg DM), whereas Spirodela had low CP content (179.64 g/kg DM) and CF content (170.57 g/kg DM). The EE content in duckweed amounted to 16.74, 46.23 and 52.47 g/kg DM for Wolffia, Spirodela and Lemna, respectively. Additionally, high ash content was observed in Spirodela (212.40 g/kg DM), Wolffia (149.34 g/kg DM) and Lemna (142.06). For standardized ileal digestibility (SIDCP), the SIDCP of all feed ingredients were within the range of 32 to 96 %. With regard to duckweed, Lemna (72 %) showed significantly higher (p < 0.05) SIDCP compared to Wolffia (69 %) and Spirodela (39 %) due to the low contents of CF and ash. Based on nutritional values, Lemna and Wolffia were grouped with corn DDGS and brewer’s grain, indicating their potential as animal feed for sustainable livestock production. HIGHLIGHTS Duckweed exhibited high protein content, ranging from 179.64 to 65 g/kg dry matter. For in vitro protein digestibility, Lemna and Wolffia had high true digestibility, amounting to 79 and 75 %, respectively. Based on nutritional values, Lemna and Wolffia were grouped with corn DDGS and brewer’s grain, indicating their potential as animal feed for sustainable livestock production. GRAPHICAL ABSTRACT

Physical and biochemical characteristics of tropical grass and legume pastures grazed by lambs

AbstractLarge areas of tropical grass pastures are not grazed by lambs because of the difficulties in managing high growth rate swards with high selective animals. The objective of this study was to evaluate the physical and biochemical characteristics of tropical pastures offered to lambs in continuous grazing. An upright grass and a shrub legume were set out in three pasture types and grazed by lambs: (1) aruana grass monoculture (AG—Panicum maximum Jacq. cv. IZ‐5), (2) pigeon pea monoculture (PP—Cajanus cajan [L.] Millsp. cv. Anão) and (3) contiguous swards (CS), half of the paddock with AG (CSAG) and half with PP (CSPP). The pastures were evaluated for structural characteristics, production, nutritional composition and antioxidant concentrations in four periods over 92 days of continuous grazing by lambs. Hand plucking samples, similar to animal diet, were collected for chemical analysis. Regarding height, the PP legume monoculture after 42 days of grazing had uncontrollable growth by the lambs, reaching 1.2 m in height. This same legume but as a CS beside AG (CSPP) was maintained at a lower and similar height throughout the experimental periods. In general, the leaf:stem ratio of the different pastures decreased over the experimental periods from 0.7 to 0.2. In most periods, the CS showed intermediary nutritional quality compared to AG and PP. The alpha‐tocopherol content was similar among swards, with an average of 137.2 ± 13.67 mg/kg of green matter (p > .05). Pigeon pea showed the highest levels of total tannin and condensed tannin at 63 and 92 days (p < .05). The use of tropical grass together with a legume provides a better physical structure of the pigeon pea for grazing lambs than when monoculture of this species.

Probiotic Potential of Bacillus Strains Isolated from Traditional Cassava Ferments (Manihot esculenta Crantz)

ABSTRACT: Probiotic potentials of Bacillus strains isolated from traditional cassava ferments, notably their growth at different pH, bile salts, temperatures, NaCl and antibiotics, their inhibition of pathogenic bacteria, non-production of hemolytic enzymes as well as the formation of biofilm were studied. These different probiotic parameters were determined according to the referenced methods. The results obtained showed that all Bacillus strains resisted acidic pH with the highest growths (7.29± 1.40) × 108 CFU/mL and (5.14±0.15) × 108 CFU /mL obtained with Bacillus toyonensis respectively at pH 2 for 24 hours and at pH 3 for 4 hours. All Bacillus strains grow well at 37°C and 44°C, despite their optimum growth temperature of 30°C. They also showed good growth at different bile salt concentrations and were multi-resistance to antibiotics Ciprofloxacin (100%), as was B. subtilis to Rifampicin (100%) but they were multi-sensitive (100%) to Amoxicillin, Imipenem, Gentamycin, Penicillin, Vancomycin, Chloramphenicol and Rifampicin except B. pumilus and B. methylotrophicus which were sensitive to Rifampicin (77%). Bacillus strains inhibited more than half of the pathogens (80.27% with S. aureus and 65.09% with E. coli). No strain showed hemolytic activity but rather a good capacity to form a biofilm (optical density ranging from 0.663 ± 00 to 3.15 ± 02 nm).

Analyzing Land Suitability for Housing in Bekasi Regency: Managing Farmland Conversion During Urban Growth

Bekasi Regency is a buffer area for Jakarta and is part of the Jakarta Metropolitan Region (JMR). Along with Karawang, this region is a major rice producer, but it is currently experiencing significant land conversion from agriculture to residential and industrial uses. Preventing this conversion is very challenging due to the high population growth in the area. To address this issue, this study aims to conduct a suitability analysis to identify areas that are unsuitable for agricultural land but still suitable for residential purposes. The factors considered in the suitability analysis include slope, distance to roads, distance to residential areas, distance to facilities and infrastructure, and distance to rivers and irrigation systems. The results of the study identify areas that are unsuitable for agriculture, allowing local governments to focus on these areas as potential sites for new residential developments. The location is situated in the southern part of Bekasi Regency, specifically in the Cikarang area and its surroundings.

Investigation of urban biodiversity and factors influencing it based on modern technologies

In the article, the development of the cities of the Shirvan plain, located in the central part of the Republic of Azerbaijan, and the impact of this development on the loss of biodiversity of the cities were analyzed. Currently, cities, where more than 50% of the world’s population live, are the main reasons for the change of natural landscapes. The development of cities and the intensity of urbanization accelerate these changes. Therefore, our research is dedicated to the current issue. During the research, preference was given to modern methods. Landsat 5, 8 and 9 satellite images of 6 cities located on the Shirvan plain were obtained. As a result of the processing and analysis of these satellite images, the development of the territory and population of the cities was studied, and their effects on the natural landscape, its components, vegetation and water bodies were analyzed. The boundaries of cities in 1975 and 2023 were determined and compared. As a result of the conducted studies, it was determined by the processing of the 1975 topo plans and the 2023 satellite images that the area of the cities has increased by at least 2 times. The high average annual growth of the population has led to the transformation of cities from small towns to medium and large cities in a short period of time. This causes the loss of biodiversity as soon as possible and accelerates this process.

Effect of the N-doping concentration on the formation of the wide carrot defect in 4H-SiC homoepitaxial layer grown by trichlorosilane (TCS) as silicon precursor

The effect of epilayer growth system, growth rate and N-doping concentration on the formation of the wide carrot defects in 4H-SiC homoepitaxial layer was investigated in this work. We found that the wide carrot defect formed on 4H-SiC epilayer only with low N-doping concentration of 5 × 1014 cm−3 grown by the SiHCl3+C2H4+H2 (TCS) system, which is different with the previous reports on the SiH4+C3H8+H2 growth system that can form such defect regardless of N-doping concentration. Besides, such wide carrot defect was never found on high speed growth of epilayer surface grown by TCS growth system. The morphology and structure of wide carrot defects were characterized by optical microscope (OM), micro-photoluminescence (PL) spectroscopy, atomic force microscope (AFM) and molten KOH etching. We speculate that the amount of wide carrot defects is related with the basal plane dislocations (BPDs) density which depends on the epitaxial growth system, growth rate of epilayer and the N-doping concentration. The formation mechanism and elimination methods of these wide carrot defects were proposed.

High temperature mechanical properties and tribological behavior of nacre-inspired Ti (C, N)/Al-Cu composites

In order to improve the toughness of aluminum matrix composites with high ceramic contents, nacre-inspired Ti (C, N)/Al-Cu composites are prepared via freeze casting and pressure infiltration, and their mechanical properties and tribological behavior are investigated. The prepared composites can maintain excellent compressive strength, hardness and wear resistance when the experimental temperature increases from 25 °C to 300 °C. This can be attributed to the stable load bearing capacity of the Ti (C, N) ceramic layer at high temperature, the high interface binding capability between Ti (C, N) and Al, as well as the high crack growth inhibition ability of “layered network” structures. Moreover, the tribo-oxide layer formed during the wear process can further improve the wear resistance of the composites.

Effects of Hydroxychloroquine on Maternal and Fetal Outcomes in Pregnant Patients with Lupus: A Systematic Review and Meta-Analysis

Background: The effects of hydroxychloroquine (HCQ) on maternal and fetal outcomes in pregnant patients with systemic lupus erythematosus (SLE) have not been fully elucidated in recent research. This study aimed to provide a more comprehensive evaluation of the efficacy and safety of HCQ in pregnant patients with SLE. Methods: A systematic search of relevant articles was conducted using Medline, Embase, Scopus, Web of Science, and the Cochrane Library from inception to October 4th, 2023. The risk of bias in the included studies was assessed using the Newcastle-Ottawa Scale or Cochrane's Quality Assessment Form. Data on maternal and fetal outcomes of the HCQ treatment groups (HCQ+) and control groups (HCQ–) were extracted, analyzed and evaluated. Pooled odds ratios (ORs), pooled relative risks (RRs), and weighted mean differences with 95% confidence intervals (95% CIs) were calculated for the meta-analysis using Stata/MP V.18. Results: This meta-analysis included 17 studies, involving a total of 2238 pregnant patients with SLE. Compared to the HCQ– groups, the HCQ+ groups exhibited a significant reduction in the incidence of preeclampsia (RR = 0.51, 95% CI: 0.37–0.71), high lupus activity (RR = 0.77, 95% CI: 0.64–0.92), gestational hypertension (OR = 0.41, 95% CI: 0.18–0.91), premature delivery (RR = 0.71, 95% CI: 0.60–0.84), and fetal growth restriction (OR = 0.61, 95% CI: 0.43–0.85). Additionally, the HCQ+ groups exhibited a significant increase in fetal birth weight of 0.21 kg (95% CI: 0.09–0.33). No significant differences were revealed in the other 15 pregnancy outcomes between the two groups. Conclusions: Despite the presence of a certain heterogeneity among the included studies, this study provides a more comprehensive evaluation of the efficacy and safety of HCQ in pregnant patients with SLE.

Reliability and Sensitivity Analysis of Wireless Sensor Network Using a Continuous-Time Markov Process

A remarkably high growth has been observed in the uses of wireless sensor networks (WSNs), due to their momentous potential in various applications, namely the health sector, smart agriculture, safety systems, environmental monitoring, military operations, and many more. It is quite important that a WSN must have high reliability along with the least MTTF. This paper introduces a continuous-time Markov process, which is a special case of stochastic process, based on modeling of a wireless sensor network for analyzing the various reliability indices of the same. The modeling has been conducted by considering the different components, including the sensing unit, transceiver, microcontroller, power supply, standby power supply unit, and their failures/repairs, which may occur during their functioning. The study uncovered different important assessment parameters like reliability, components-wise reliability, MTTF, and sensitivity analysis. The critical components of a WSN are identified by incorporating the concept of sensitivity analysis. The outcomes emphasize that the proposed model will be ideal for understanding different reliability indices of WSNs and guiding researchers and potential users in developing a more robust wireless sensor network system.

Effect of substrate temperature on the growth mechanism of FeSe superconducting films

Abstract Among all the iron-based superconductors (IBSs), Fe-chalcogenides (Fe-Ch) possess the advan tages of simple structure, non-toxicity, low anisotropy and the potential for high-field applications.One of the most effective methods for preparing Fe-Ch films is pulsed laser deposition (PLD). However, high quality film growth is challenged by the significant volatility difference between the iron
and chalcogens (S, Se, Te), which affects stoichiometric transfer from target to substrate and subsequently impacts superconductivity. Currently, there is limited research on the correlation between the growth mechanism and preparation conditions of Fe-Ch films, particularly in explaining chalcogen volatility during deposition. Technically, PLD offers various adjustable parameters, among
which the substrate temperature (Ts) is the most critical one affecting film quality. It governs particle behavior on the substrate including adsorption, diffusion, bonding reactions, crystallization processes while also strongly affecting volatilization rates. In this study, we fabricated a series of FeSe films using PLD at different Ts ranging from 25 ℃ to 750 ℃.We reveal in detail the impact of
competitive processes between Se volatilization and reactive crystallization of Fe/Se on film quality. The optimal film was obtained at Ts=500 ℃ with a composition ratio of Fe1.01Se. We also investigate the correlations between Ts and film crystallinity, surface morphology, along with their influence on superconductivity. Additionally, the pinning mechanism in FeSe film grown at the
optimal Ts was briefly analyzed. Our results provide reliable experimental evidence regarding the growth mechanism of FeSe films while revealing comprehensive insights into how Ts affects both film quality and performance.

(Keynote) Epitaxial Si/SiGe Multi-Stacks: From Stacked Nano-Sheet to Fork-Sheet and CFET Devices

After a short description of the evolution of metal-oxide-semiconductor (MOS) device architectures and the corresponding requirements on epitaxial growth processes, the manuscript describes the material properties of complicated Si/SiGe multi-layer stacks used for complementary field effect transistor (CFET) devices. They contain two different Ge concentrations and have been grown using conventional process gases. A relatively high growth temperature is used to obtain acceptable Si and SiGe growth rates. Still island growth has been suppressed for Ge concentrations up to 40%. Excellent structural and optical material properties of the Si/SiGe multi-layer stack will be reported, with up to 3 + 3 Si channels in the top and bottom part of the stack, respectively. The absence/presence of lattice defects has been verified by room temperature photoluminescence measurements. Photoluminescence measurements at low temperatures are used to study band-to-band luminescence from individual sub-layers and to illustrate the optical material quality of the CFET stack.

Effects of burnt sawdust ashes from timber species on the strength properties of laterite-interlocking blocks

The most basic problem facing man is shelter, apart from food. This problem is acute in Ghana and other developing countries due mainly to the high growth rate of the population, inflation, unemployment and poor economic resources. Today in Ghana both middle and low income earners can hardly afford their own houses. From one point of view one can see that some of the materials used in building are of good quality and can last. The study aimed to partially replace ordinary Portland cement (oPc) with burnt sawdust ash (BSDA) from different timber species (Wawa, Mansonia, Teak, Odum, Ceiba, Essah and Mahogany) in making interlocking laterite blocks by replacing 0–30 wt %. Mix proportion was 1:8 (cement + BSDA: laterite) with a 0.60 water-to-cement ratio. 528 specimens of size 185 mm × 220 mm × 120 mm were produced and cured at normal temperature and humidity under shady and sunny conditions for 7, 14, 21 and 28 days. Compressive and tensile strengths were subsequently evaluated. However, an initial strength increase was observed with curing time for specific wood species (Wawa, Mansonia, Teak, Odum, Essah, Ceiba, and Mahogany). Notably,Wawa, Mansonia and Odum ash exhibited superior strength performance at 10–20% replacement levels, potentially satisfying relevant standards for load-bearing wall construction. This research suggests that up to 10% replacement with Wawa, Mansonia or Odum BSDA presents a promising eco-friendly approach for partially substituting oPc in LIB production.

Improved nutritional and antioxidant properties of black soldier fly larvae reared on spent coffee grounds and blood meal by-products

Black Soldier Fly larvae (BSFL) are a promising and sustainable alternative to obtain proteins. Due to their high growth rate and ability to use different substrates as feeding stocks, BSFL can be also used to valorize food waste. Thus, the aim of this research was to unravel the potential use of Spent Coffee Grounds (SCG) and blood meal alone or mixed as feedstocks for BSFL and the nutritional changes for BSFL meal, especially after simulated human in vitro digestion and fermentation. Chicken feed was used as a control. Chicken feed showed the highest BSFL growth (P < 0.05) compared with blood meal and the mix made of blood meal and SCG; the latter caused the lowest growth. The meal obtained from BSFL fed with blood meal had the highest protein content, as well as the highest levels of short chain fatty acids (SCFAs) produced after in vitro fermentation by the human gut microbiota. On the other hand, the meal from larvae fed with SCG showed higher antioxidant capacity than the others in the DPPH, FRAP and ABTS assays. The digestibility of macronutrients, release of antioxidant capacity and production of SCFAs of the BSFL meal were improved when using these substrates, compared to chicken feed.

Study on sperm cryopreservation of hybrid fish derived from Carassius cuvieri (♀) × Carassius auratus red var (♂)

Cryopreservation of sperm is an effective method for conserving germplasm resources in fish genetic breeding. The high-quality hybrid fish (WR) derived from white crucian carp (Carassius cuvieri, WCC, ♀) and red crucian carp (C. auratus red var., RCC, ♂), possesses valuable traits such as high survival rates, strong resistance, and rapid growth, representing an important germplasm resources of crucian carp. This study compared the effects of different antifreeze solutions on sperm viability among three varieties (WR, WCC, and RCC) and examined changes in enzyme activity, fertilization rates, and hatching rates after cryopreservation, aiming to enhance the cryogenic sperm cryopreservation technique in hybrid fish and investigate the mechanisms underlying spermatozoa damage caused by cryopreservation. The results showed that the antifreeze combination of D14 with 15 % dimethyl sulfoxide (DMSO) had the best effect in preserving the sperm of WR and WCC, while D20 with 10 % DMSO was the optimal combination for RCC sperm. After ultra-low temperature preservation, the longevity, fertilization, and hatching rates of frozen sperm were significantly lower (P < 0.05) compared to fresh sperm. The enzyme activities of superoxide dismutase (SOD), lactate dehydrogenase (LDH), and creatine kinase (CK) were significantly decreased (P < 0.05) in spermatozoa, whereas they showed a significant increase (P < 0.05) in sperm plasma. Succinate dehydrogenase (SDH) activity was significantly reduced (P < 0.05) in frozen spermatozoa of RCC compared to fresh spermatozoa, and exhibited lower activity in frozen spermatozoa of WCC and WR. Additionally, SDH activity was significantly elevated (P < 0.05) in frozen sperm plasma, and glutathione reductase (GR) activity was significantly lower (P < 0.05) in both frozen sperm plasma and spermatozoa across all three species. The study demonstrated that cryopreservation had a significant effect on the enzyme activities of spermatozoa and sperm plasma in all three species. These findings provide important technical support for the conservation of high-quality fish germplasm resources, particularly for novel varieties resulting from distant hybridization in fish.

Synergistic regulation of chassis cell growth and screening of promoters, signal peptides and fusion protein linkers for enhanced recombinant protein expression in Bacillus subtilis

Growth-advantageous microbial chassis cells are beneficial for shortening fermentation period and boosting biomolecule productivity. This study focused on enhancing recombinant proteins synthesis efficiency in Bacillus subtilis by CRISPRi-mediated metabolism regulation for improved cell growth and screening expression elements. Specifically, by repressing odhA gene expression to reallocate cellular resource and overexpressing atpC, atpD and atpG genes to reprogram energy metabolism, the growth-advantageous chassis cell with high specific growth rate of 0.63 h−1 and biomass yield of 0.41 g DCW/g glucose in minimum medium was developed, representing 61.54 % and 46.43 % increasements compared to B. subtilis 168. Subsequently, using screened optimal P566 promoter and (EAAAK)3 protein linker, secretory bovine alpha-lactalbumin (α-LA) titer reached 1.02 mg/L. Finally, to test protein synthesis capability of cells, intracellular GFP, secretory α-LA and α-amylase were expressed with P566 promoter, representing 43.76 %, 75.49 % and 82.98 % increasements. The growth-advantageous B. subtilis chassis cells exhibit their potential to boost bioproduction productivity.

Organotin(IV) compounds loaded in thermo- and pH-responsive smart polymeric nanocarriers based on poly(DEGMA-co-OEGMA)-b-poly(DEAEM) a drug releasing system and in vitro anticancer activity

Nanocarriers in cancer treatment are important for transport and release of insoluble drugs. In this work, block thermo- and pH-responsive copolymers based on poly(di(ethylene glycol) methyl ether methacrylate-co-oligo(ethylene glycol) methyl ether methacrylate) (PDO) and poly(2-(N,N-diethylamino)ethyl methacrylate) (PDEA) were tested. At pH 7.4 and 37 °C, the title polymers formed micelles which were used for the loading and release of diorganotin(IV) complexes (LSnR2), where L is a Schiff base ligand and R = n-butyl (LSnBu2) or cyclohexyl (LSnCy2). Results revealed that the PDO-b-PDE block copolymers could enhance the solubility of LSnR2(IV) compounds in PBS at pH = 7.4, resulting in good loading capacity (%DLC) and loading efficiency (%DLE), and better release performance (pH-dependent and T-dependent) than the free compound. In vitro cytotoxic activity was evaluated by the sulforhodamine B (SRB) assay against a normal cell line, African green monkey kidney fibroblast (COS-7) and seven human cancer cell lines prostate (PC-3), leukemia (K-562), colon (HCT-15), lung (SKLU-1), central nervous system glia (U-251), breast Strogen receptor-positive (MCF-7) and breast hormone-independent (MDA-MB-231). The non-loaded block copolymers were non-cytotoxic, but the loaded ones showed high cell growth inhibition against human cancer cell lines. Results confirmed that these temperature and pH-sensitive polymeric systems are excellent candidates for the loading and release of potential metallodrugs, such as LSnR2, against diverse types of cancers.

Biocontrol Activity of Bacillus altitudinis CH05 and Bacillus tropicus CH13 Isolated from Capsicum annuum L. Seeds against Fungal Strains.

In this study, seed-surface-associated bacteria from fresh fruits of Capsicum spp. were analyzed to explore potential isolates for biocontrol of phytopathogenic fungal strains. A total of 76 bacterial isolates were obtained from three different species of chili pepper (C. annuum L., C. pubescens R. & P., and C. chinense Jacq.), and two isolates were selected via mycelial growth inhibition assays based on their production of volatile organic compounds (VOCs) against six fungal strains. Genomic analysis identified these isolates as Bacillus altitudinis CH05, with a chromosome size of 3,687,823 bp and with 41.25% G+C, and Bacillus tropicus CH13, with a chromosome size of 5,283,706 bp and with 35.24% G+C. Both bacterial strains showed high mycelial growth inhibition capacities against Sclerotium rolfsii, Sclerotinia sp., Rhizoctonia solani, and Alternaria alternata but lower inhibition capacities against Colletotrichum gloesporoides and Fusarium oxysporum. VOC identification was carried out after 24 h of fermentation with 64 VOCs for B. altitudinis CH05 and 53 VOCs for B. tropicus CH13. 2,5-Dimethyl pyrazine and acetoin had the highest relative abundance values in both bacterial strains. Our findings revealed that seed-surface-associated bacteria on Capsicum spp. have the metabolic ability to produce VOCs for biocontrol of fungal strains and have the potential to be used in sustainable agriculture.

ХОЗЯЙСТВЕННО-БИОЛОГИЧЕСКИЕ ПОКАЗАТЕЛИ ПРОДУКТИВНОСТИ РАЗНЫХ ОБРАЗЦОВ АМАРАНТА AMARANTHUS HYPOCHONDRIACUS L. В УСЛОВИЯХ ПРЕДГОРИЙ РСО-АЛАНИЯ

The introduction into cultivation of new plant species that combine not only high yields and nutritional benefits, but also resistance to diseases and pests is an important task for the agricultural industry. The main feature of amaranth is its high performance and active growth, which allows it to be used as a crop with a short growing season, and amaranth also has high seed performance, unlike other traditional crops. The studies were carried out at the experimental site of the Research Institute of Biotechnology of the Federal State Budgetary Institution of Higher Education Gorsky State Agrarian University. The material for the study was collection samples of amaranth, selected in the full flowering phase. Economic and biological indicators of productivity of different samples of amaranth VR-99, K-51, K-61, K-63 of the genus ( Amaranthus hypochondriacus L.) were established. These amaranth samples are mid-season, the growing season of which is on average 125 days. According to biometric indicators, the studied amaranth samples are of medium height, from 157 to 173 cm. On average, the biomass yield of samples K-61 and K-63 was 440-593.4 c/ha, respectively. The yield of amaranth samples ( Amaranthus hypochondriacus L.) K-51, BP-99 was 406-438.9 c/ha, respectively. The dynamics of the assimilating surface area and leaf blade area in the flowering phase for sample VR-99 was 63.75 (thousand m2/g). In the seed ripening phase, the leaf area was 142.8 (thousand m2/g). The total photosynthetic potential of the leaf surface was 2272.05 million m2 day/ha. Amaranth samples of the genus Amaranthus hypochondriacus L. (BP-99, K-51, K-61, K-63), due to their unique properties, are promising for use as a fodder crop, and its inclusion in the agrophytocenosis of the foothill zone of North Ossetia will provide high-quality forage.

Dysbiosis and Regulation of Gut Microbiota in Type 2 Diabetes Mellitus.

Type 2 diabetes mellitus is a serious metabolic disease having a high growth rate and becoming a global threat. An unhealthy lifestyle, food intake, and genetic susceptibility are the major factors responsible for this metabolic disorder. This disease results in hyperlipidemia, hyperglycemia, glucose intolerance, restricted insulin synthesis, and insulin resistance. Despite a variety of treatments currently available, cases of diabetes and resulting complications are on the rise. One promising approach to diabetes focuses on gut microflora and their associated metabolites. Gut microbiota has attracted widespread attention due to its crucial role in disease pathophysiology. This study explores the dysbiosis in the human gut microflora in Type 2 Diabetes Mellitus and how the gut microbiota influences metabolites related to T2DM. It also sheds light on early identification and targeted intervention for this. Understanding these mechanisms could potentially lead to more effective strategies for managing and preventing T2DM. The findings of our literature study are that gut microbiota can serve as biomarkers for early disease detection. Finally, we also highlight gut microecological therapeutic strategies focused on shaping the gut flora to emphasize the improvement of T2DM progression.
