Microbe-Friendly Plants Enable Beneficial Interactions with Soil Rhizosphere Bacteria by Lowering Their Defense Responses.

The use of plant growth-promoting rhizobacteria presents a promising addition to conventional mineral fertilizer use and an alternative strategy for sustainable agricultural crop production. However, genotypic variations in the plant host may result in variability of the beneficial effects from these plant-microbe interactions. This study examined growth promotion effects of commercial vegetable crop cultivars of tomato, cucumber and broccoli following application with five rhizosphere bacteria. Biochemical assays revealed that the bacterial strains used possess several nutrient acquisition traits that benefit plants, including nitrogen fixation, phosphate solubilization, biofilm formation, and indole-3-acetic acid (IAA) production. However, different host cultivars displayed genotype-specific responses from the inoculations, resulting in significant (p < 0.05) plant growth promotion in some cultivars but insignificant (p > 0.05) or no growth promotion in others. Gene expression profiling in tomato cultivars revealed that these cultivar-specific phenotypes are reflected in differential expressions of defense and nutrient acquisition genes, suggesting that plants can be categorized into "microbe-friendly" cultivars (with little or no defense responses against beneficial microbes) and "microbe-hostile" cultivars (with strong defense responses). These results validate the notion that "microbe-friendly" (positive interaction with rhizosphere microbes) should be considered an important trait in breeding programs when developing new cultivars which could result in improved crop yields.

First-principles study of selective CO2 activation to methanol on PdZn/TiO2: Unveiling Zn/Pd ratio on catalysis performance

In this study, a series of Pd(8-n)Znn/TiO2(n=0–8) were investigated via density functional theory (DFT) to understand the influence of Zn/Pd ratio on their catalysis performance of conversion CO2 to methanol. It is revealed that Zn prefers to replace the bottom-layered Pd when its molar concentration in composition increases. For all surface models, interface between cluster and support plays a key role in CO2 stabilization and activation. Increasing Zn/Pd ratio could weaken the binding strength of CO2 over catalyst, which further hinders the “RWGS” pathway while promotes the “Formate” pathway. Based on the calculation results, a Brønsted–Evans–Polanyi (BEP) relation between the activation barrier (Ea) of key elementary steps from both mechanisms and the binding strength of key intermediates has been established, from which the optimum Zn/Pd ratio leading to the best catalysis performance has been determined. Moreover, it is found that water inclusion in the system does not change the Ea of rate-determining step much even though it has a promotion effect on OH formation steps. Overall, this work provides some meaningful insight into the influence of cluster composition on the catalysis performance of PdZn-based catalyst and provides valuable information about rational design of the supported bimetallic catalyst.

Effect of antibiotic growth promoters (AGPs) on feed conversion ratio (FCR) of broiler chickens: A meta-analysis

Antibiotics have been used for a long time as growth promoters in the poultry industry for growth and health benefits. However, recent studies reflected little, no, or negative impacts of using antibiotics for growth promotion purposes. This study was designed to examine the overall effect of antibiotic supplementation on the feed conversion ratio (FCR) in broiler chickens as a performance indicator and assess different covariates for explaining heterogeneity in response to the use of antibiotics as growth promoters. In this regard, FCRs obtained from articles that compared diets with and without antibiotics for broiler chickens were extracted from electronic databases (PubMed, Web of Science, and Google Scholar) as per PRISMA guidelines. The database comprised 42 scientific articles containing 74 experiments totaling 19,562 chickens. A basic meta-analysis and subgroup analysis were performed to assess the overall impact of antibiotic growth promoters (AGPs) on FCR of broiler chickens while a meta-regression analysis was used to assess different covariates (breed, antibiotic dose, location, time, presence of anticoccidial in the feed, antibiotic type, and housing type) to explain variations in true effect size of the studies. The basic meta-analysis of these studies revealed an overall improvement in FCR by 2.8 % (p < 0.05) due to addition of AGPs than the control group with the confidence interval range from 1.3 to 4.3 % and the prediction interval ranging between -10 and 16 %. The covariates, including breed, dose and location, provided the optimum model fit and explained 53 % of variations in the FCR across different studies. In summary, an overall marginal improvement has been observed in mean FCR of broiler chickens along with a wide range of variations in response to use of AGPs. The variations in true effects among these studies are subject to several confounding effects, particularly breed, dose and location. Considering the marginal positive effect of antibiotic usage in chicken performance, we recommend against using of AGP.

Groundwater Geochemistry in the Karst-Fissure Aquifer System of the Qinglian River Basin, China

The Qinglian River plays a significant role in China’s national water conservation security patterns. To clarify the relationship between hydrogeochemical properties and groundwater quality in this karst-fissure aquifer system, drilling data, hydrochemical parameters, and δ2H and δ18O values of groundwater were analyzed. Multiple indications (Piper diagram, Gibbs diagram, Na+-normalized molar ratio diagram, chloro-alkaline index 1, mineral saturation index, and principal component analysis) were used to identify the primary sources of chemicals in the groundwater. Silicate weathering, oxidation of pyrite and chlorite, cation exchange reactions, and precipitation are the primary sources of dissolved chemicals in the igneous-fissure water. The most relevant parameters in the karst water are possibly from anthropogenic activities, and other chemicals are mostly derived from the dissolution of calcite and dolomite and cation exchange reactions. Notably, the chemical composition of the deep karst water from the karst basin is mainly influenced by the weathering of carbonate and cation exchange reactions and is less affected by human activities. The hydrogeochemical properties of groundwater in the karst hyporheic zone are influenced by the dissolution of carbonates and silicates, evaporation, and the promotion effect of dissolution of anorthite or Ca-containing minerals. Moreover, the smallest slope of the groundwater line from the karst hyporheic zone among all groundwater groups revealed that the mixing effects of evaporation, isotope exchange in water–rock interaction or deep groundwater recharge in the karst hyporheic zone are the strongest. The methods used in this study contribute to an improved understanding of the hydrogeochemical processes that occur in karst-fissure water systems and can be useful in zoning management and decision-making for groundwater resources.

Social Protection: Aspirations and Limitations of an Expanding Agenda

This article unpacks the expanding social protection agenda, in which promotive objectives have been added to the original welfarist or safety net aim of protection. It draws out the resulting tensions, potentials and limits, to inform a discussion of where African social protection is and is headed. After tracing several initial drivers of social assistance in Africa – structural adjustment, food insecurity and famines, HIV and AIDS, and conflict – it shows how promotive effects were increasingly advocated along three pathways: investment of social transfers, building human capital, and linking social with economic support. International development agencies added their own priorities to this agenda, drawing on evidence of promotive impacts to convince national governments. Drawing on Zambia’s experience, we conclude that, while the expanded agenda redirects attention to questions of economic development, its transformative potential remains limited due to a persistent focus on the micro‑level and a failure to build effective linkages to other sectors.

Effectiveness of Cartoons, Comics, and Animation-Based Sexual Health Promotion and Education Interventions: A Scoping Review

Objective Sexual health education is crucial for promoting healthy sexual behaviors among people of all ages. Interventions involving cartoons, comics, and animations have emerged as effective tools due to their engaging and accessible nature. This scoping review explores the effectiveness of these interventions across different time frames and age groups. Methods Using the PICOS framework and PRISMA guidelines for scoping reviews, a review was conducted across 14 databases to include relevant studies published between 2000 and 31 May 2024. Results Analyzing 51 intervention studies meeting the inclusion/exclusion criteria revealed varied outcomes in interventions that highlight a significant shift in focus from developing educational tools and empowering youth in the earlier period (2000–2010) to implementing advanced technology-based cartoons, comics, and animations interventions and addressing diverse populations in the later period (2011–2024). The results of these studies were predominantly positive, with many reporting significant improvements in knowledge, behaviors, and engagement. Conclusion While many studies report positive outcomes, further investigation is needed into the long-term impact of digital-based cartoons, comics, and animation interventions on behavior change and health outcomes. Research should also explore the effectiveness of these tools in different cultural and socioeconomic contexts to ensure their broad applicability. Ongoing research and iterative development are warranted to ensure that these interventions continue to evolve and meet the changing needs of users in an increasingly digital world across diverse populations

How promotion mix helps sustain brand sales during market transitions: insights from the pharmaceutical industry

Purpose Pharmaceutical marketers use detailing, sampling and direct-to-consumer advertising (DTCA) to promote a branded prescription drug (brand drug) to health-care professionals and consumers. These promotion mix elements help raise brand awareness, increase prescription likelihood and guard a product market against competing brand drugs. However, the extent to which these elements remain effective when a brand drug goes off patent and its marketing exclusivity expires, allowing low-price generics to enter the market, remains unclear. This study aims to explore the effectiveness of promotion mix elements before and after the market entry of a generic drug. Design/methodology/approach The authors collected and analyzed a panel data set of 41 brand drugs from 7 therapeutic classes between 2007 and 2014 (3,201 observations) using the two-stage control function approach to address potential endogeneity. Findings The effectiveness of promotion mix elements changes significantly, but not in a universally uniform way, during a market transition. Detailing and DTCA are increasingly effective after a brand drug’s generics enter the market. In contrast, sampling is more effective before the market transition. The positive effects of sampling on brand sales are stronger when the price of a brand drug is higher than the average price of its competing brands. Sampling also helps amplify the positive influences of detailing and DTCA on brand sales. Research limitations/implications This study shows that pharmaceutical promotion is not equally effective in the brand drug market with/without generic competitors. Detailing and DTCA are increasingly effective when generic competition intensifies. In contrast, the distribution of free drug samples is less effective after more generic drugs enter the market. Practical implications Incumbent brands’ promotion expenditures often drop dramatically when the expiration of their patents is near, a practice that likely continues after generics enter the market. Taking into consideration these industry norms and their findings, the authors suggest that promotional decisions during a market transition should not overly focus on cutting promotional expenditures across the board. Since a firm’s promotional expenditure tends to be expensive, factoring in information on the effectiveness of each promotion mix element helps marketers make well-informed strategic decisions on resource allocation during the transition from a market without generics to a market with generics. Originality/value Previous studies do not explicitly account for structural changes in the brand drug market over time. However, the expiration of patent and marketing exclusivity marks a transitional period in which a brand drug eventually competes with its generic counterparts. Given the criticality of such structural change, the authors examine brand drugs’ promotion effectiveness in the presence of their generic counterparts.

A Study on the Impact of Digital Transformation on Enterprise Performance: The Mediating Role of Dual Innovation and the Moderating Role of Management Power

The findings indicate the following: (1) Digital transformation can effectively promote improving enterprise performance and dual innovation levels. (2) Digital transformation positively impacts enterprise performance primarily through enhanced exploitative innovation, exploratory innovation, dual innovation balance, and complementarity. (3) Managerial power positively moderates the promotion effect of digital transformation on enterprise performance. (4) The impact of digital transformation on enterprise performance is more significant in the eastern and central regions, high-tech industries, and enterprises with good profitability. Based on these results, enterprises are suggested to accelerate digital transformation, fully tap the synergistic driving effect of dual innovation, strengthen the management’s cognition and leadership of digital transformation, and implement dynamic and differentiated digital transformation strategy based on region, industry, and their own characteristics.

RNF2 promotes chondrosarcoma progression by regulating ubiquitination and degradation of CBX7

ObjectiveChondrosarcoma (CHS) is resistant to conventional chemotherapy and radiotherapy and currently lacks effective treatment options when in advanced stages. Accordingly, this research investigated the mechanism of RNF2/CBX7 in CHS to drive the development of molecularly targeted drugs for CHS.MethodsRNF2 and CBX7 levels were detected in CHS cells and tissues. RNF2 and CBX7 expression was modulated through cell transfection to examine their effects on cell proliferation, apoptosis, migration, and angiogenesis. The correlation between RNF2 and CBX7 levels was determined, and the ubiquitination level of CBX7 was tested. Protein synthesis was blocked in RNF2-knockdown/overexpressing cells with CHX to assess the effect of RNF2 on CBX7 stability. JJ012 cells transfected with LV-sh-RNF2 were subcutaneously injected into nu/nu nude mice to ascertain the action of RNF2 in the growth and metastasis of CHS.ResultsRNF2 was highly expressed in CHS cells and tissues. RNF2 knockdown curbed CHS cell proliferation, migration, and angiogenesis while promoting apoptosis. RNF2 knockdown in JJ012 cells upregulated CBX7 protein levels and reduced CBX7 ubiquitination, whilst RNF2 had no effect on CBX7 mRNA expression. CBX7 knockdown partially nullified the repressing effects of RNF2 knockdown on CHS cell proliferation, migration, and angiogenesis, and CBX7 overexpression partially abolished the promotional effects of RNF2 overexpression. LV-sh-RNF2 prominently restricted tumor growth and weight and declined lung metastatic nodules and Ki-67-positive cells in mice.ConclusionRNF2 fosters CHS progression by elevating CBX7 degradation via the ubiquitination pathway.

Popping-Up Poster: A Pin-Based Promotional Poster Device for Engaging Customers through Physical Shape Transformation

Promotional media, such as paper posters and digital signage, are installed in shopping malls to recommend products and services. However, it has been reported that many customers tend not to be interested in these promotional media and do not receive the information. When product information is not communicated effectively, advertisers are unable to convey the information they wish to share with customers, and customers miss the opportunity to receive valuable information. To address such issues, a lot of methods have been proposed to make people aware of the presence of media; however, there are not many methods that take into account the delivery of product information to customers. In this study, we propose Popping-Up Poster, a pin-based poster device designed to capture customer attention and convey information through dynamic shape changes. To verify the effectiveness of the proposed system, field experiments were conducted in a café, where its promotional effects were compared with those of traditional promotional media, including paper posters and digital signage. These results show that Popping-Up Poster has the potential to be more effective in recommending products and influencing customer product choices compared to conventional promotional media.

Simulation study on additive-promoted microwave dehydration of lignite

ABSTRACT Microwave dehydration technology has been widely used in coal processing methods due to its unique advantages. Adding additives with high dielectric loss to coal can enhance the microwave absorption capacity of coal, so as to effectively improve the dehydration process. In order to understand the change and distribution of multi-fields in the microwave drying process of lignite under the action of different additives, verify the experiment and reduce the cost and number of experiments, this paper established a multi-field coupling model of electromagnetic field and heat and mass transfer of multiphase porous media based on COMSOL Multiphysics, so as to simulate the microwave drying process of lignite. The results show that the distribution areas of electromagnetic field, temperature field, and vapor in coal are basically the same, while the distribution of liquid water is just the opposite. With the enhancement of additive promotion effect, the parts with strong electromagnetic field strength increase, the hot spots of temperature field increase, the maximum temperature, and minimum temperature increase, and the water content in coal samples decreases. The promotion effect of additives on the microwave dehydration process of lignite is consistent with the experiment.

Kinetic investigation on palladium‐catalyzed carbonylation of allyl alcohol

AbstractPalladium‐catalyzed carbonylation of allyl alcohol to 3‐butenoic acid has been investigated. A significant effect of halide promoters, p‐tolylsulfonic acid (TsOH), water, solvents, and PPh3 concentration activity and selectivity has been studied. Detailed kinetics of this reaction was investigated in a temperature range of 363–383 K. The influence of parameters such as stirring speed, allyl alcohol, catalyst, benzyltriethylammonium chloride (BTEAC), TsOH concentrations, and CO partial pressures on the activity and selectivity has been studied. An empirical rate equation was suggested and found to be fairly consistent with observed rate data. In addition, the activation energy and kinetic parameters were evaluated.
