15-5648.07 ng/mL (4.98-11.95 µM)), compared to the D10 strain (6202.00-9659.70 ng/mL (12.75-19.85 µM)).

The synthetized derivatives, possessing enhanced antimalarial activity against the CQ-resistant strain of P. falciparum, appear to be interesting antimalarial drug candidates.Guava (Psidium guajava) leaves are commonly used in the treatment of diseases. They are considered a waste product resulting from guava cultivation. The leaves are very rich in essential oils (EOs) and volatiles. This work represents the detailed comparative chemical profiles of EOs derived from the leaves of six guava varieties cultivated in Egypt, including Red Malaysian (RM), El-Qanater (EQ), White Indian (WI), Early (E), El-Sabahya El-Gedida (ESEG), and Red Indian (RI), cultivated on the same farm in Egypt. The EOs from the leaves of guava varieties were extracted by hydro-distillation and analyzed with GC-MS. The EOs were categorized in a holistic manner using chemometric tools. The hydro-distillation of the samples yielded 0.11-0.48% of the EO (v/w). The GC-MS analysis of the extracted EOs showed the presence of 38 identified compounds from the six varieties. The sesquiterpene compounds were recorded as main compounds of E, EQ, ESEG, RI, and WI varieties, while the RM variety attained the highest contenshowed that they are rich in biologically active compounds, particularly β-caryophyllene, trans-nerolidol, globulol, and D-limonene. These could be considered as added value for pharmacological and industrial applications. Further study is recommended to confirm the chemical variations of the studied varieties at a molecular level, as well as their possible medicinal and industrial uses.Crop mixtures are often beneficial in crop rotations to enhance resource utilization and yield stability. While targeted management, dependent on the local species composition, has the potential to increase the crop value, it comes at a higher expense in terms of field surveys. As fine-grained species distribution mapping of within-field variation is typically unfeasible, the potential of targeted management remains an open research area. In this work, we propose a new method for determining the biomass species composition from high resolution color images using a DeepLabv3+ based convolutional neural network. Data collection has been performed at four separate experimental plot trial sites over three growing seasons. The method is thoroughly evaluated by predicting the biomass composition of different grass clover mixtures using only an image of the canopy. With a relative biomass clover content prediction of R2 = 0.91, we present new state-of-the-art results across the largely varying sites. Combining the algorithm with an all terrain vehicle (ATV)-mounted image acquisition system, we demonstrate a feasible method for robust coverage and species distribution mapping of 225 ha of mixed crops at a median capacity of 17 ha per hour at 173 images per hectare.Periodontitis consists of a progressive destruction of tooth-supporting tissues. Considering that probiotics are being proposed as a support to the gold standard treatment Scaling-and-Root-Planing (SRP), this study aims to assess two new formulations (toothpaste and chewing-gum). 60 patients were randomly assigned to three domiciliary hygiene treatments Group 1 (SRP + chlorhexidine-based toothpaste) (control), Group 2 (SRP + probiotics-based toothpaste) and Group 3 (SRP + probiotics-based toothpaste + probiotics-based chewing-gum). At baseline (T0) and after 3 and 6 months (T1-T2), periodontal clinical parameters were recorded, along with microbiological ones by means of a commercial kit. As to the former, no significant differences were shown at T1 or T2, neither in controls for any index, nor in the experimental groups for adherent gingiva and gingival recession. Conversely, some significant differences were found in Group 2 and 3 for the other clinical indexes tested. Considering microbiological parameters, no significant differences were detected compared to baseline values for any group, except in Group 2 and 3 at T2 only for the percentage of the orange complex pathogens and for the copies/microliter of Prevotella intermedia and Fusobacterium nucleatum. Accordingly, although colonization of probiotic bacteria has not been assessed in this study, the probiotics tested represent a valid support to SRP with a benefit on several clinical indexes and on specific periodontopathogens. Despite this promising action, the relationship between the use of probiotics and improvement in clinical parameters is still unclear and deserves to be further explored.Between 2015 and 2018, we identified the presence of three so-far-unknown Bluetongue virus (BTV) strains (BTV-MNG1/2018, BTV-MNG2/2016, and BTV-MNG3/2016) circulating in clinical healthy sheep and goats in Mongolia. Virus isolation from EDTA blood samples of BTV-MNG1/2018 and BTV-MNG3/2016 was successful on the mammalian cell line BSR using blood collected from surveillance. After experimental inoculation of goats with BTV-MNG2/2016 positive blood as inoculum, we observed viraemia in one goat and with the EDTA blood of the experimental inoculation, the propagation of BTV-MNG2/2016 in cell culture was successful on mammalian cell line BSR as well. However, virus isolation experiments for BTV-MNG2/2016 on KC cells were unsuccessful. Furthermore, we generated the complete coding sequence of all three novel Mongolian strains. For atypical BTV, serotyping via the traditional serum neutralization assay is not trivial. We therefore sorted the 'putative novel atypical serotypes' according to their segment-2 sequence identities and their time point of sampling. Hence, the BTV-MNG1/2018 isolate forms the 'putative novel atypical serotype' 33, the BTV-MNG3/2016 the 'putative novel atypical serotype' 35, whereas the BTV-MNG2/2016 strain belongs to the same putative novel atypical serotype '30' as BTV-XJ1407 from China.The particle size distribution significantly affects the material properties of the additively manufactured parts. In this work, the influence of bimodal powder containing nano- and micro-scale particles on microstructure and materials properties is studied. Moreover, to study the effect of the protective atmosphere, the test samples were additively manufactured from 316L stainless steel powder in argon and nitrogen. The samples fabricated from the bimodal powder demonstrate a finer subgrain structure, regardless of protective atmospheres and an increase in the Vickers microhardness, which is in accordance with the Hall-Petch relation. The porosity analysis revealed the deterioration in the quality of as-built parts due to the poor powder flowability. The surface roughness of fabricated samples was the same regardless of the powder feedstock materials used and protective atmospheres. The results suggest that the improvement of mechanical properties is achieved by adding a nano-dispersed fraction, which dramatically increases the total surface area, thereby contributing to the nitrogen absorption by the material.
