Effects of drugs commonly used in Sars-CoV-2 infection on renal tissue in rats
No full textAim: In December 2019, the coronavirus disease was caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Some drugs were repurposed for this disease treatment. Hydroxychloroquine (HCQ), favipiravir (FAV), molnupiravir (MOL), and dexamethasone (DEX) were widely used for the treatment of the disease. To increase the success of the treatment of coronavirus disease, there was used some of these drugs in combination. On the other hand, limited studies report these drugs’ side effects. Therefore, this study was designed to evaluate the possible effects of these drugs and their combinations on the kidney tissues of rats without viral load. Materials and Methods: Male Wistar albino rats were divided into control, HCQ, FAV, HCQ+FAV, HCQ+FAV+DEX, MOL, and MOL+DEX groups. At the end of the experiment, the serum kidney tissue samples were taken. Serum samples were analyzed for urea and creatinine. Kidney tissue samples were assessed as histopathological and immunohistochemical for heat shock protein 60 (HSP60), caspase-3, and receptor-interacting protein kinase-3 (RIPK3). Results: Urea and creatinine levels were within the normal range in all groups. Histopathologically, all drugs and their combinations caused tubular degeneration. On the other hand, histopathological alterations were more prominent in the HCQ group. The oxidative stress marker HSP60 was significantly increased in FAV, MOL, and MOL+DEX groups, while it was similar to the control group in the HCQ groups. Apoptosis marker caspase-3 expression was found to be prominently higher in other drug groups except the FAV group. Expression of RIPK3, a marker of necroptosis, was significantly increased in all drug groups. Conclusion: Taken together, the data of our study show that the administration of all drugs alone and in combination may cause structural damage to the kidney. Furthermore, our results indicate that HCQ can exhibit more damaging effects compared to other drugs
Effect of foliar spray of yeast extract and potassium nitrate on yield and fruit quality on Ziziphus jujuba L. trees
Get PDFThe present study was conducted during the two successive seasons, 2017 and 2018, at King Saud University, Saudi Arabia, to investigate the effects of foliar sprays on Ziziphus jujuba trees by yeast extract at 1% and 2% and potassium nitrate (KNO3) at 1% and 2%. All treatments were foliar applied twice (December 15–January 15) in both seasons. Yield and fruit quality were studied. Treatments significantly improved yield, physical fruit and fruit chemical characteristics, moisture content, chlorophyll a, b and total chlorophyll by most tested treatments in both seasons than the control (water only). Yeast spray treatments significantly decreased juice content vitamin C (mg/100 g), while KNO3 spray treatments increased juice content vitamin C in both seasons. It can be concluded that foliar application with KNO3 at 2% recorded the best treatment to obtain the highest yield, fruit weight, flesh weight, fruit volume, fruit length and fruit diameter, while yeast extract at 2% treatment gave the highest TSS% and total sugar contents in this study.The present study was conducted during the two successive seasons, 2017 and 2018, at King Saud University, Saudi Arabia, to investigate the effects of foliar sprays on Ziziphus jujuba trees by yeast extract at 1% and 2% and potassium nitrate (KNO3) at 1% and 2%.

The impact of foliar dikegulac and Asahi SL sprays on the shoot production of highbush blueberry nursery plants
Get PDFThe aim of the present study was to assess the usefulness of dikegulac (2,3:4,6-di-O-isopropylidene-α-Lxylo-2-hexulofuranosonic acid) and Asahi SL (sodium ortho- and para-nitrophenolate, sodium 5-nitroguaiacolate) in production of highbush blueberry nursery plants. The experiment was carried out on three cultivars of highbush blueberry: ‘Bluecrop’, ‘Brigitta blue’ and ‘Darrow’. Pot plants were treated two times with dikegulac (0.1%) or/and Asahi SL (0.2%) foliar sprays in the late spring. The reaction of blueberry clones to the tested chemicals was different. Dikegulac-treated plants developed significantly more shoots making them a good and efficient source of cuttings when using the traditional propagation. Dikegulac limited the shoot elongation of two studied cultivars (‘Bluecrop’, ‘Darrow’). It also reduced the size of leaf blades but generally did not change the fluorescence and the relative content of chlorophyll. The influence of dikegulac in the applied dose was much stronger than the impact of nitrophenolates. The application of Asahi SL, alone or together with dikegulac, did not give any spectacular and advantageous effects.The aim of the present study was to assess the usefulness of dikegulac (2,3:4,6-di-O-isopropylidene-α-Lxylo-2-hexulofuranosonic acid) and Asahi SL (sodium ortho- and para-nitrophenolate, sodium 5-nitroguaiacolate) in production of highbush blueberry nursery plants.

Localisation of active substances in Hedera helix leaves and Linaria vulgaris shoots used in pharmaceutical and cosmetic industry
Get PDFAlthough Hedera helix and Linaria vulgaris are considered toxic plants, their extracts containing many bioactive compounds are commonly used in the pharmaceutical and cosmetics industries. Plant secretory structures are considered the primary site of synthesis and accumulation of many valuable metabolites. The presence of secretory structures and the location of active substances in H. helix leaf petioles and L. vulgaris inflorescence shoots were detected using light microscopy and histochemical and fluorescence tests. The analyses showed schizogenic secretory ducts in the H. helix petioles and capitate glandular trichomes on the surface of the L. vulgaris shoots. The secretion and secretory cells of the H. helix ducts and the L. vulgaris trichomes contained acidic and neutral lipids, sesquiterpenes, polyphenols, tannins, flavonoids, phenolic acids, neutral and acidic polysaccharides, proteins and alkaloids. Data on the secretory structures and taxonomic and morpho-anatomical traits of the analysed raw materials may help evaluate their quality (falsification)
Effects of biochar applications on growth, nutrient content and biochemical properties of Ocimum basilicum L.
Get PDFThis study investigated the effects of biochar treatments on the growth, nutrient content and some biochemical properties of basil. Biochars obtained from two different biomasses, rice husk (RBC) and tomato harvest waste (TBC), were applied at a dose of 2% to the growing medium consisting of a 1 : 1 soil and peat mixture. No biochar-added medium (1 : 1 soil and peat) was used as a control. The experiment was established in a completely randomized design with six replications for each treatment. At the end of the study, the height, number of lateral branches, total herb weight, and leaf weight of the plants were measured. In addition, chlorophyll contents in SPAD (Soil Plant Analysis Development), different nutrients and total phenolics contents, and antioxidant activities were analyzed. As a result of the study, the effects of biochar treatments differed depending on the biomass source. RBC significantly increased plant height, total herb weight, and leaf weight while negatively affecting the number of lateral branches. TCB did not cause any significant variation in plant height and number of lateral branches. While RBC provided a slight increase in leaf weight compared to the control, it did not cause a significant change in plant height, total herb weight, and the number of lateral branches. Except for a slight increase in K content due to RBC application, both biochar treatments did not cause a significant increase in leaf nutrient content. While RBC treatment did not cause a significant change in total phenol, it caused an increase in antioxidant activity. TBC application decreased the SPAD value from 22.4 in the control to 20.4.This study investigated the effects of biochar treatments on the growth, nutrient content and some biochemical properties of basil.

Functional characterization of ZjPYL8 from sour jujube: enhancing the sensitivity of stomata and roots to ABA in Arabidopsis thaliana
Get PDFAbscisic acid (ABA) is a plant hormone that plays a crucial role in regulating plant growth, development, and adaptation to stress. The growth of Ziziphus jujuba Mill. var. spinosa (Bunge) Hu ex H. Chou, commonly known as Suanzao in Chinese, is significantly influenced by environmental factors, particularly drought and salt stresses. In this study, we isolated and characterized a putative ABA receptor, ZjPYL8, from Sour jujube. To investigate the effects of ZjPYL8 overexpression on ABA-responsive pathways, we introduced it into Arabidopsis thaliana (A. thaliana) and examined the resulting phenotypes. Our results demonstrated that overexpression of ZjPYL8 in A. thaliana led to a significant reduction in stomatal aperture and root length under ABA treatment, while the wild type (WT) was relatively insensitive to ABA. Moreover, ZjPYL8 transgenic plants exhibited shorter roots under salt treatment than the WT did. These findings suggest that the overexpression of ZjPYL8 in A. thaliana enhances the plant's resistance to stress and support the hypothesis that ZjPYL8 serves as a putative ABA receptor in Sour jujube, which may improve the plant's adaptability to drought and salt stresses. ZjPYL8 appears to mediate plant responses to ABA, similar to most ABA receptors in A. thaliana, such as stomatal closure and root length.Abscisic acid (ABA) is a plant hormone that plays a crucial role in regulating plant growth, development, and adaptation to stress.

Inoculating mycorrhiza fungi and growth-promoting bacteria and mulch of plant residues improve yield and essential oil production of anise (Pimpinella anisum L.).
Get PDF This experiment aimed to investigate the effects of Pseudomonas growth-promoting bacteria, mycorrhizal fungi, and living mulch on morphological and physiological traits of a medicinal herb, Pimpinella anisum. The study was carried out using a factorial design in a randomized complete block design arrangement with three replications during the crop year of 2019–2020. The first factor includes the use of biological fertilizers (fungi and bacteria) at four levels: 1) control (without the use of biological fertilizers), 2) mycorrhizal fungi, 3) growth-promoting bacteria, 4) combined use of growth-promoting bacteria and fungi. The second factor includes mulch (plant residues) at four levels: 1) control, 2) wheat straw (3 t/ha), 3) berseem clover mulch (2 t/ha), 4) living berseem clover mulch, cultivated among the rows of anise. Cultivation of clover and anise was done simultaneously. Results showed that the combined use of biological fertilizers (Glomus intraradices and Pseudomonas putida) along with living clover mulch led to a significant increase in seed yield, harvest index, and the essential oil yield of anise. Moreover, under such conditions, the highest seed yield (930.8 kg/ha) and the highest essential oil yield (18.15 kg/ha) increased by 48% and 51% compared to the control, respectively. We found that the use of living clover mulch led to a significant increase in biological yield, seed yield, and the number of umbels and umbellets of anise. Accordingly, the highest biological yield of 5332 kg/ha was obtained, which was 55% higher than the control. The extraction of essential oil components showed that α-pinene and para-cymene showed the highest amount and significant components of essential oil. Moreover, the maximum amount of α-pinene (2.277%) observed upon fungi and living clover application along with inter-row clover cultivation (increased by 60% compared to the control), and the maximum value of para-cymene (0.2300%) was obtained upon bacteria and living clover inoculation along with inter-row clover cultivation (increased by 59% compared to the control). Finally, according to the perspectives of sustainable and organic agriculture in medicinal plant cultivation, the use of ecologically compatible inputs such as bacteria and fungi that stabilize food elements, as well as the use of living and non-living plant mulches, can be used as a tool to increase the quantitative and qualitative performance of the anise plant.

Influence of medium type and culture method on the multiplication efficiency of Chlorophytum comosum (Thunb.) Jacques in in vitro conditions
Get PDFIn response to the challenges posed by modern plant micropropagation techniques, a promising technology for growing shoots temporary immersed in nutrient solution (temporary immersion system, TIS) using SETIS™ bioreactors has been developed. In this experiment, the suitability of this technology for the propagation of Chlorophytum comosum (Thunb.) Jacques was assessed. In vitro culture was carried out using a conventional technique on solid media and liquid media using the SETIS™ bioreactor. In addition, two culture media differing in macro- and micronutrient content (Murashige & Skoog and Rugini OM), while having the same set of phytohormones were evaluated in both systems. Explants obtained from the flower stalk of the plants were used to establish the culture. The effectiveness of the cultures after the first and second subculture was assessed. The study has demonstrated that the efficiency of liquid culture carried out using the SETIS™ bioreactor is higher compared to the conventional culture. The highest multiplication coefficient, fresh weight of regenerants and RGR index value in bioreactor cultures was recorded on Rugini OM medium. No statistically significant differences were found between MS medium and Rugini OM medium in terms of shoot length and vigour with this method of culture. When using the conventional method, better results can be achieved with MS medium. This research can be considered as a first step towards the production of Chlorophytum comosum (Thunb.)

An improved adaptive neuro-fuzzy inference system for hydrological drought prediction in Algeria
No full textDrought has negative impacts on water resources, food security, soil degradation, desertification and agricultural productivity. The meteorological and hydrological droughts prediction using standardized precipitation/runoff indices (SPI/SRI) is crucial for effective water resource management. In this study, we suggest ANFISWCA, an adaptive neuro-fuzzy inference system (ANFIS) optimized by the water cycle algorithm (WCA), for hydrological drought forecasting in semi-arid regions of Algeria. The new model was used to predict SRI at 3-, 6-, 9-, and 12 -month accumulation periods in the Wadi Mina basin, Algeria. The results of the model were assessed using four criteria; determination coefficient, mean absolute error, variance accounted for, and root mean square error, and compared with those of the standalone ANFIS model. The findings suggested that throughout the testing phase at all the sub-basins, the proposed hybrid model outperformed the conventional model for estimating drought. This study indicated that the WCA algorithm enhanced the ANFIS model's drought forecasting accuracy. The pro-posed model could be employed for forecasting drought at multi-timescales, deciding on remedial strategies for dealing with drought at study stations, and aiding in sustainable water resources management.Lund UniversityOpen access funding provided by Lund University
