This is a complex process that undergoes multiple stages of development before yielding a final product. The final biofertilizer is used by legumes-protein-rich crops in symbiosis with rhizobia to enable biological nitrogen fixation increasing natural soil fertility. This study aims to determine the optimal formulation of a rhizobial biofertilizer to improve the performance of soybean (Glycine max L. cv. Docko). To this end, soybean seeds obtained from IRAD were coated with different formulations derived from locally sourced materials. Palm kernel oil was used as an adhesive in one group, while corn powder served as an adhesive in another. The coated seeds were then sown in the field. The results indicate that the combination of pigeon pea powder + sugarcane molasses, with palm kernel oil as an adhesive, produced the best nodulation (nitrogen fixation). This formulation also led to significant improvements in growth (+350%) and total nitrogen content (+1100%) compared to the bacterial broth inoculum control (B0) (P ≤ 0.01). These findings represent a significant advancement in improving nitrogen-fixing bacterial inoculants and enhancing soil fertility for the sustainable cultivation of soybeans in this tropical soil.展开更多

The aim was also to test their specific influence on the cementitious matrix of hardened concrete. Several laboratory tests were conducted on samples from Brazzaville and Pointe-Noire. To develop a variety of concrete formulations meeting rheological criteria (deformability, bleeding, segregation) and create an optimal concrete formulation approach considering its microstructural and compacting matrix, a good granular distribution was planned, using two types of sand (rolled and crushed). This involved correcting the rolled sand with variable proportions (30% to 50%) of crushed sand. The results from the eight concrete formulations studied, using the Dreux-Gorisse method, showed that six formulations produced the expected results. Compressive strengths at 28 days ranged from 25 to 36.75 MPa. As a result, formulation 3 appears to be the best, with a mechanical strength of 36.75 MPa at 28 days, compared to formulation 1 (33.75 MPa), formulation 4 (27.25 MPa), and formulation 2 (26.65 MPa) for the Brazzaville locality. For the Pointe-Noire locality, formulation 8 was judged the best, with a characteristic mechanical strength of 29.70 MPa at 28 days, followed by formulation 7 (27.30 MPa), formulation 5 (22.80 MPa), and formulation 6 (18.30 MPa). In summary, the concretes formulated with raw sand showed better results than those with improved sands. The same was true for concrete formulations using rolled sand and gravel.展开更多

The objective of this study was to propose some spice formulations based on local ingredients in order to reduce the use of chemical spices in the preparation of different dishes. The Design of Experiments (DOE) methodology was used for the formulation of the spices and their physicochemical, nutritional and sensory characteristics were evaluated by standardized and standard methods. The results obtained showed lipid contents (g/100 g DM) ranging from 10.41 ± 0.26 to 15.64 ± 0.68, total sugars from 4.39 ± 0.32 to 5.46 ± 0.31, protein from 3.65 ± 0.17 to 12.04 ± 0.35 and ash from 5.83 ± 0.01 to 7.02 ± 0.01. The polyphenol content ranged from 9.09 ± 1.60 to 11.33 ± 0.90, and the flavonoid content ranged from 0.65 ± 0.03 to 1.08 ± 0.13. The sensory analysis carried out showed that the spices have generally satisfactory organoleptic characteristics. These results constitute new information in the diet of populations and are an alternative to the chemical spices used in their cooking.展开更多

Only a very small proportion of the apple is processed into juice. The aim of this work is to enhance the value of cashew apples by transforming them into jam. Specifically, the aim was first to characterize the sensory properties of cashew apple jam formulations using baobab powder as a source of pectin and then to optimise the formulations. A Box-Behken design with pH, Sugar, and Baobab as factors was used to model and characterize the jam sensory descriptors, and a multivariate analysis with SensomineR was used to characterize the jam formulations. The desirability function was used to optimise the formulations. The results show globally significant regressions at the 0.05 threshold for the sensory descriptors Gelling, Brilliance, Smell, Sweetness, and (-)Astringency, with the exception of (-)Salinity. The R2 coefficients are greater than 80%. The factors studied could have effects on the sensory descriptors of cashew jam formulations. The Baobab had the main effect on the gelling, smell, and astringency of the jams. Brilliance depended on the added sugar. A product effect (p < 0.001) was observed for the descriptors Smell, Gelling, Brilliance, and Sweetness, as these allowed the panelists to find differences between the formulations. Optimum jam formulation can be achieved with 51.56% sugar and 2.12% Baobab at a pH of 3.15. Cashew apple jam using Baobab offers opportunities to add value to apples that have long been abandoned in the field. It would be important to find conditions for prolonged storage of this jam.展开更多

Firstly, the key point of this method is to decompose the original model into a kind of decoupled two-dimensional eigenvalue problem by cylindrical coordinate transformation and Fourier series expansion, and deduce the crucial essential pole conditions. Secondly, we define a kind of weighted Sobolev spaces, and establish a suitable variational formula and its discrete form for each two-dimensional eigenvalue problem. Furthermore, we derive the equivalent operator formulas and obtain some prior error estimates of spectral theory of compact operators. More importantly, we further obtained error estimates for approximating eigenvalues and eigenfunctions by using two newly constructed projection operators. Finally,some numerical experiments are performed to validate our theoretical results and algorithm.展开更多

文摘BACKGROUND Mesalamine is the recommended first-line treatment for inducing and maintaining remission in mild-to-moderate ulcerative colitis(UC).However,adherence in real-world settings is frequently suboptimal.Encouraging collaborative patient-provider relationships may foster better adherence and patient outcomes.AIM To quantify the association between patient participation in treatment decisionmaking and adherence to oral mesalamine in UC.METHODS We conducted a 12-month,prospective,non-interventional cohort study at 113 gastroenterology practices in Germany.Eligible patients were aged≥18 years,had a confirmed UC diagnosis,had no prior mesalamine treatment,and provided informed consent.At the first visit,we collected data on demographics,clinical characteristics,patient preference for mesalamine formulation(tablets or granules),and disease knowledge.Self-reported adherence and disease activity were assessed at all visits.Correlation analyses and logistic regression were used to examine associations between adherence and various factors.RESULTS Of the 605 consecutively screened patients,520 were included in the study.The median age was 41 years(range:18-91),with a male-to-female ratio of 1.1:1.0.Approximately 75%of patients reported good adherence at each study visit.In correlation analyses,patient participation in treatment decision-making was significantly associated with better adherence across all visits(P=0.04).In the regression analysis at 12 months,this association was evident among patients who both preferred and received prolonged-release mesalamine granules(odds ratio=2.73,P=0.001).Patients reporting good adherence also experienced significant improvements in disease activity over 12 months(P<0.001).CONCLUSION Facilitating patient participation in treatment decisions and accommodating medication preferences may improve adherence to mesalamine.This may require additional effort but has the potential to improve long-term management of UC.
文摘Background:Luliconazole is an imidazole antifungal drug mainly used to treat dermatophytic infections including tinea pedis,tinea cruris,and tinea corporis.Objective:The purpose of this research was to synthesize a transferosomal gel incorporating luliconazole for external applications.Materials and methods:The preparation method employed thin film hydration to prepare transferosomes loaded with luliconazole with lecithin and tween 80 at different concentrations.The transferosomes formed were characterized in terms of particle size and entrapment efficiency.Finally,the prepared transferosomes were applied in a carbopol gel base and characterized for drug content,pH,spreadability,viscosity,in vitro release profile,and antifungal studies.Results:The synthesized luliconazole transferosomes had high entrapment efficiency of 74.45%,and 92.75%,with particle size ranging between 60 and 200 nm.The shape of the transferosomes was established using scanning electron microscopy;the results depicted spherical-shaped vesicles.The in vitro release study also suggested that the entrapment efficiency influences in vitro release where there is a negative relationship between the two.The gel formulation revealed a good antifungal effect.Conclusion:The luliconazole transferosomal gel exhibited a sustained release profile of the drug and thus may lessen the number of applications required,thereby enhancing patient compliance.
文摘This work focuses on the formulation of a dietary cold sauce,mayonnaise,which combines the therapeutic properties of two basic ingredients:PSO(Pumpkin Seed Oil)and quail egg,both of which are renowned for their high functional properties.PSO is essentially made up of unsaturated fatty acids(50%to 65%)including linoleic acid,from the omega 6 family,oleic acid(20%to 50%),a monounsaturated fatty acid(omega 9),cucurbitin,phytosterols,tri-terpenes and vitamin E(3.5 mg%).The nutritional,fatty acid,vitamin and mineral compositions of the mayonnaise compared with the ingredients,the physico-chemical characteristics of the quail egg,the PSO and the tasting of the mayonnaise were determined and gave results in terms of variable contents which are recorded in Tables 2-8.The results obtained were satisfactory.Mayonnaise,a semi-solid emulsion of oil in water with viscoelastic properties due to the network formed by lipoproteins adsorbed around neighbouring drops of oil,was prepared using the ratio of quail egg and PSO 1/4.This study may offer an alternative way of making dietary sauces.

文摘The effectiveness of fluopyram suspension concentrate against pine wilt disease(PWD)is limited by spraying efficiency and water dependence.A traditional dust formulation with strong dispersibility can overcome these shortcomings.However,its efficacy against PWD remains uncertain.This study evaluated the translocation of fluopyram dust within tree tissues,soil and water degradation,and its effective control against PWD.Nursery tests showed effective prevention;field tests showed dust absorption and translocation into pine tissues.Thirty days following application,residual concentrations in soil were low at 0.09 mg kg^(−1);no detectable residues were found in water samples.Three years after applying fluopyram,its effectiveness increased to approximately 87%.Based on this study,fluopyram had a half-life of 346 d with persistence lasting up to three years.This provides valuable insight for managing PWD through dust applications.
文摘Background:Fuke Huahuang formulation(FHF)is widely used in the treatment of vaginitis,with clinical evidence indicating its promising anti-inflammatory properties.Methods:We explored the bioactive components and potential mechanisms of FHF for treating vaginitis,and reveal its pharmacological activities against vaginitis.Results:A total of 12 anti-inflammatory components in FHF and 584 pharmacological targets were identified.Furthermore,1427 vaginitis-associated targets were identified,and 184 intersection targets between FHF and vaginitis were constructed for network analysis.Gene Ontology and pathway analysis revealed that the therapeutical targets of FHF against vaginitis are involved in modulating inflammatory stress,enhancing immunoregulation,reconstructing the microenvironment,and suppressing cell damage.Molecular docking analysis further suggested the possible direct binding of the bioactive compounds of FHF(fumarine)to the core targets,including AKT Serine/Threonine Kinase 1(AKT1),Signal Transducer and Activator of Transcription 3(STAT3),and nuclear factor-kappaB(NF-κB).Experimental validation found that FHF-treated vaginitis rats exhibited reduced intracellular AKT1,STAT3,and NF-κB protein expressions.Conclusion:Overall,we identified the bioactive compounds and pharmacological mechanisms of FHF against vaginitis,thus offering a theoretical fundament for exploring FHF for treating vaginitis in the future.

文摘BACKGROUND Diabetic nephropathy(DN)is a major complication of diabetes,marked by progressive renal damage and an inflammatory response.Although research has investigated the pathological mechanisms underlying DN,effective treatment options remain limited.AIM To evaluate the therapeutic impact of Shenzhuo formulation(SZF)on a DN mouse model and to examine its potential molecular mechanisms using transcriptomic and metabolomic approaches.METHODS We established a DN mouse model through a high-fat diet combined with streptozotocin(STZ)injection,followed by SZF treatment.We analyzed SZF’s effects on gene expression and metabolite profiles in renal tissues of DN mice using transcriptomics and metabolomics techniques.Additionally,based on transcriptomic and non-targeted metabolomic findings,we further assessed SZF’s influence on the expression of factors related to the cytochrome P450(CYP450)-mediated arachidonic acid(AA)metabolism pathway,as well as its effects on inflammation and oxidative stress.RESULTS SZF intervention significantly decreased hyperglycemia and mitigated renal function impairment in DN mice.Pathological analysis revealed that SZF treatment improved renal tissue damage,reduced fibrosis,and diminished glycogen deposition.Transcriptomic analysis indicated that SZF influenced mRNA expression of CYP450-related genes,including Cyp2j13,Cyp2b9,Pla2 g2e/Cyp4a12a,Cyp4a32,Cyp2e1,and Cyp4a14.Non-targeted metabolomic results demonstrated that SZF altered the levels of metabolites associated with the AA metabolic pathway,including 5,6-EET,14,15-EET,phosphatidylcholine,and 20-HETE.Further experiments showed that SZF upregulated the expression of CYP4A and CYP2E proteins in renal tissue,as well as CYP2J and CYP2B proteins.Additionally,SZF significantly reduced the expression of inflammatory factors in renal tissue,enhanced antioxidant enzyme activity,and alleviated oxidative stress.CONCLUSION SZF exerts anti-inflammatory and antioxidant effects by regulating CYP450-mediated AA metabolism,leading to improved renal function and improved pathological state in DN mice.
文摘Idiopathic pulmonary fibrosis(IPF)has a poor prognosis if left untreated;therefore,early treatment with pirfenidone is crucial.Lei et al conducted a retrospective analysis to evaluate the effectiveness of early pirfenidone treatment on lung function in 113 patients with IPF.In addition to other research,pirfeni-done has demonstrated efficacy in patients at all stages of IPF once correct diagnosis has been made.In advanced IPF,we include the requirement for pirfenidone.Therefore,it is essential to choose an appropriate method of adminis-tration method,such as inhalation.This may circumvent the drawbacks of the high cost and possible adverse effects of this drug.

文摘Cashew processing in Côte d’Ivoire focuses only on the cashew nut, to the detriment of the apple. Only a very small proportion of the apple is processed into juice. The aim of this work is to enhance the value of cashew apples by transforming them into jam. Specifically, the aim was first to characterize the sensory properties of cashew apple jam formulations using baobab powder as a source of pectin and then to optimise the formulations. A Box-Behken design with pH, Sugar, and Baobab as factors was used to model and characterize the jam sensory descriptors, and a multivariate analysis with SensomineR was used to characterize the jam formulations. The desirability function was used to optimise the formulations. The results show globally significant regressions at the 0.05 threshold for the sensory descriptors Gelling, Brilliance, Smell, Sweetness, and (-)Astringency, with the exception of (-)Salinity. The R2 coefficients are greater than 80%. The factors studied could have effects on the sensory descriptors of cashew jam formulations. The Baobab had the main effect on the gelling, smell, and astringency of the jams. Brilliance depended on the added sugar. A product effect (p < 0.001) was observed for the descriptors Smell, Gelling, Brilliance, and Sweetness, as these allowed the panelists to find differences between the formulations. Optimum jam formulation can be achieved with 51.56% sugar and 2.12% Baobab at a pH of 3.15. Cashew apple jam using Baobab offers opportunities to add value to apples that have long been abandoned in the field. It would be important to find conditions for prolonged storage of this jam.

文摘In this work, an efficient spectral method is proposed to solve the fourth-order eigenvalue problem in cylinder domain. Firstly, the key point of this method is to decompose the original model into a kind of decoupled two-dimensional eigenvalue problem by cylindrical coordinate transformation and Fourier series expansion, and deduce the crucial essential pole conditions. Secondly, we define a kind of weighted Sobolev spaces, and establish a suitable variational formula and its discrete form for each two-dimensional eigenvalue problem. Furthermore, we derive the equivalent operator formulas and obtain some prior error estimates of spectral theory of compact operators. More importantly, we further obtained error estimates for approximating eigenvalues and eigenfunctions by using two newly constructed projection operators. Finally,some numerical experiments are performed to validate our theoretical results and algorithm.

文摘Traditional Chinese medicine(TCM)exerts integrative effects on complex diseases owing to the characteristics of multiple components with multiple targets.However,the syndrome-based system of diagnosis and treatment in TCM can easily lead to bias because of varying medication preferences among physicians,which has been a major challenge in the global acceptance and application of TCM.Therefore,a standardized TCM prescription system needs to be explored to promote its clinical application.In this study,we first developed a gradient weighted disease-target-herbal ingredient-herb network to aid TCM formulation.We tested its efficacy against intracerebral hemorrhage(ICH).First,the top 100 ICH targets in the GeneCards database were screened according to their relevance scores.Then,SymMap and Traditional Chinese Medicine Systems Pharmacology(TCMSP)databases were applied to find out the target-related ingredients and ingredient-containing herbs,respectively.The relevance of the resulting ingredients and herbs to ICH was determined by adding the relevance scores of the corresponding targets.The top five ICH therapeutic herbs were combined to form a tailored TCM prescriptions.The absorbed components in the serum were detected.In a mouse model of ICH,the new prescription exerted multifaceted effects,including improved neurological function,as well as attenuated neuronal damage,cell apoptosis,vascular leakage,and neuroinflammation.These effects matched well with the core pathological changes in ICH.The multi-targets-directed gradient-weighting strategy presents a promising avenue for tailoring precise,multipronged,unbiased,and standardized TCM prescriptions for complex diseases.This study provides a paradigm for advanced achievements-driven modern innovation in TCM concepts.

文摘The exopolysaccharide matrix of diazotrophic cyanobacteria was used to integrate phosphorus(P)and potassium(K)solubilizing bacteria,enhancing the survival of plant growth-promoting rhizobacteria,and ultimately the survival of bacteria in the rhizosphere for better plant growth.A new biofilm-based formulation comprising the diazotrophic cyanobacteria Anabaena AMP2,P-solubilizing Bacillus megaterium var.phosphaticum PB1,and K-solubilizing Rhizobium pusense KRBKKM1 was tested for efficacy in rice.The growth medium with half-strength BG-11 medium supplemented with 3%glucose showed best for biofilm formation under in vitro conditions.Analysis of the methanolic extract of the cyanobacterial-bacterial biofilm(CBB)showed the activity of antioxidants,such as 2-methoxy phenol and pentadecane,which are proven to improve plant-microbe interactions and plant growth,respectively.Treatment of rice seeds with CBB extract at 100 mL/kg or 200 mL/kg showed significant enhancement in germination rate and seedling length.Therefore,a pot culture experiment with the CBB formulations was carried out,and different growth and yield parameters were recorded.Principal component analysis showed that plant growth,yield,soil dehydrogenase activity,and soil chlorophyll content were positively correlated with rice plants amended with vermiculite-based CBB at 2 kg/hm^(2) followed by a spray with aqueous CBB formulation at 5 mL/L at 15 and 30 d after rice transplanting grown with a 25%reduced level of nitrogen/phosphorus/potassium chemical fertilizers than the recommended dose.Further,Pearson correlation analysis showed that yield was positively correlated with soil dehydrogenase(r=0.92**)and soil chlorophyll content(r=0.96**).We concluded that CBB could be used as a novel biofilm-based bio-inoculant to increase rice productivity and crop fitness as a component in integrated nutrient management and sustainable organic farming strategies with reduced chemical fertilizers.
