Relationship between Media Coverage and Public Opinion during Political Campaigns in South Africa

Purpose: The aim of the study was to assess the relationship between media coverage and public opinion during political campaigns in South Africa. Materials and Methods: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: The study indicated that media coverage significantly influences public opinion by shaping perceptions, framing issues, and highlighting particular aspects of candidates and policies. During political campaigns, the media serves as a primary source of information for the electorate, often determining the salience of issues and the prominence of candidates. Extensive and favorable media coverage can enhance a candidate's visibility and credibility, potentially swaying undecided voters and reinforcing the views of supporters. Conversely, negative coverage can damage a candidate's public image and diminish their support base. The framing of news stories, the selection of topics, and the tone of coverage play critical roles in this process. For instance, media emphasis on certain campaign issues can lead to a phenomenon known as agenda-setting, where the public perceives these issues as more important. Additionally, the portrayal of candidates through specific narratives can influence voter perceptions, contributing to the formation of public opinion. The interplay between media coverage and public opinion underscores the media's power in shaping political landscapes and affecting electoral outcomes. Implications to Theory, Practice and Policy: Agenda-setting theory, framing theory and spiral of silence theory may be used to anchor future studies on assessing the relationship between media coverage and public opinion during political campaigns in South Africa. From a practical standpoint, political campaigns must adopt strategic media engagement to shape public opinion effectively. In terms of policy, there is a pressing need for regulations that promote accountability and transparency in media coverage during political campaigns.

Enhanced production of yellow fever virus through tailored culture media optimization

In the present study, an initial screening was conducted using 12 types of cell culture media, and four media with the best performance were selected for further study. The optimization of four media blend for YFV production was evaluated using an Augmented simplex centroid mixture design. Among all the different models that were investigated, the quadratic model was found to be the most appropriate model for exploring mixture design. It was found that M10 exhibited the greatest impact on YFV production, followed by M9, M4, and M1. The utilization of M1 and M4 media individually yielded higher compared to their blends with other media. The YFV titers were reduced when M1 media was combined with other media. The utilization of M9 and M10 media in combination resulted a higher viral yield compared to their respective concentrations. The optimal ratio for achieving a higher titer of YFV from primary CEFs was found to be approximately 38:62, with M9 and M10 being the most favorable media blend. The use of a media mixture led to a significant increase of virus titer up to 2.6 × 108 PFU/ml or 2 log titer yield, which is equivalent to 1.92 × 105 doses, without any changes to growth conditions or other process factors. This study concluded that the utilization of a mixture design could be efficiently employed to choose the optimal combination of media blends for enhanced viral production from cell culture.

Exceptional functionalized ionic liquid@metal–organic framework: A high-efficiency desulfurization platform for organic sulfide oxidation by reactive oxygen species

There is a challenge with designing catalysts that simultaneously possess active sites for catalyzing the generation of reactive oxygen species (ROSs) and effectively overcoming mass transfer resistance in oil–water biphasic systems. In this study, a novel, highly efficient oxidative desulfurization (ODS) strategy is proposed that uses an ILs-loaded metal–organic framework (MOF) coupled material as a catalyst. The IL@MOF ([Hnmp]HSO4@MIL-125(Ti)) coupled material prepared by loading [Hnmp]HSO4 onto MIL-125(Ti) has catalytic-adsorption synergistic capability. It demonstrated outstanding oxidative desulfurization performance by achieving nearly a 100 % removal of dibenzothiophene (DBT) from model oil with a dosage of 0.04 g IL@MOF per 10 mL of model fuel under mild conditions (50 °C, 10 min). By comparing the experimental results with the characterization data, it is suggested that [Hnmp]HSO4@MIL-125(Ti) converts superoxide radicals (•O2−) into 1O2 through oxygen vacancies (Ov) and that the catalytic action of Ti on the oxidation of DBT is primarily based on a 1O2-driven non-free radical mechanism. [Hnmp]HSO4@MIL-125(Ti) serves as a favorable medium for contact to be made between ROSs and sulfides, which indicates an efficient catalytic-adsorption synergy.

Key factors capturing the willingness to use automated vehicles for travel in China.

With the continuous advancement of technology, automated vehicle technology is progressively maturing. It is crucial to comprehend the factors influencing individuals' intention to utilize automated vehicles. This study examined user willingness to adopt automated vehicles. By incorporating age and educational background as random parameters, an ordered Probit model with random parameters was constructed to analyze the influential factors affecting respondents' adoption of automated vehicles. We devised and conducted an online questionnaire survey, yielding 2105 valid questionnaires. The findings reveal significant positive correlations between positive social trust, perceived ease of use, perceived usefulness, low levels of perceived risk, and the acceptance of automated vehicles. Additionally, our study identifies extraversion and openness as strong mediators in shaping individuals' intentions to use automated vehicles. Furthermore, prior experience with assisted driving negatively impacts people's inclination toward embracing automated vehicles. Our research also provides insights for promoting the adoption of automated vehicles: favorable media coverage and a reasonable division of responsibilities can enhance individuals' intentions to adopt this technology.

In vitro propagation and DNA barcoding of the rare near endemic Plantago sinaica (Barnéoud) plant in Saint Katherine, Sinai

Plantago sinaica is a rare perennial shrub near-endemic to Egypt and found in Saint Katherine Protectorate in Sinai. The first successful in vitro propagation protocol was conducted to protect the plant outside its natural reserves. Shoot tip, stem node section, cotyledonary node, and root explants separated from in vitro germinated seedlings were cultured in vitro on Murashige and Skoog (MS) medium enriched with different concentrations and types of cytokinins. It was found that 6-benzyl adenine (BA) is the most efficient cytokinin. MS medium containing 3.33 µM BA and 0.54 µM α-naphthalene acetic acids (NAA) produced 10.25 and 11.30 shoots/explant using shoot tip and stem node section, respectively. Conversely, MS medium + 2.22 µM BA + 0.54 µM NAA produced 13.25 shoots from root explants. Surprisingly, the cotyledonary node explants favored MS medium free from plant growth regulators (PGRs), which produced only 4.25 shoots/explant. The multiplied shoots were rooted successfully with a 100% rooting percentage on half MS medium containing 1.23 or 2.46 µM indole-3-butyric acid (IBA). In vitro, rooted plantlets were efficiently transferred to the greenhouse with a 90% survivability. Finally, the plant was identified using three DNA barcodes; 1,5-bisphosphate carboxylase/oxygenase large subunit (rbcL), plastid photosystem II protein D1 intergenic spacer region (psbA–trnH), and Internal Transcribed Spacer (ITS) barcodes. Additionally, psbA–trnH and ITS were novel and submitted to the GenBank databases for the first time for Plantago sinaica. Our study supports the United Nations Sustainable Development Goal number 15, which is to preserve, restore and reinstate sustainable usage of terrestrial ecosystems and to stop biodiversity loss.

Identifying the Biological Characteristics of Anthracnose Pathogens of Blueberries (Vaccinium corymbosum L.) in China

Vaccinium corymbosum L., commonly known as blueberry, is a valuable small fruit tree in terms of its economic significance and is primarily found in China within the regions of Heilongjiang and Jilin provinces. Additionally, it thrives in the areas spanning the middle and lower reaches of the Yangtze River. Beyond their economic value, blueberries play a crucial role within forest ecosystems, serving as a significant energy source and source of nutrients. Their presence contributes significantly to fostering stability, enhancing biodiversity, and acting as an indicator of environmental quality within forest ecosystems. Since August 2022, an unknown leaf disease has been found on a large scale in blueberry fields in Nanjing, Jiangsu Province, China. The disease causes leaf curling, wilting, and even early defoliation, severely reducing the yield and production value of blueberries. The pathogenicity test confirmed the virulence of the isolates (NG5-1, NG5-2, NG5-3, NG5-4, N2-1, and N2-2) against V. corymbosum. The two pathogens were identified as Colletotrichum fructicola and C. aenigma by observing the morphological characteristics of the isolates and combined with multilocus phylogenetic analyses (ITS, CAL, ACT, TUB2, ApMat, and GAPDH). Blueberry anthracnose, caused by C. aenigma, is the first report of this disease in China. The biological characteristics of C. aenigma were investigated under different conditions, including temperature, pH, light conditions, culture medium, and carbon and nitrogen sources. The optimal temperature for growth was determined to be within the range of 25–30 °C; C. aenigma exhibits optimal growth at a pH of 7–8. Mycelial growth is favored under conditions of partial light, whereas complete darkness promotes spore production. It was found that PDA medium was the most favorable medium for C. aenigma mycelial growth, and MM medium was the best medium for spore production; the most suitable carbon sources for colony growth and spore production were sorbitol and glucose, respectively, and the most suitable nitrogen source was peptone. This study furnishes a theoretical foundation for a more scientifically informed approach to the prevention and control of anthracnose on V. corymbosum.

Precise Methylation Yields Acceptor with Hydrogen-Bonding Network for High-Efficiency and Thermally Stable Polymer Solar Cells.

Utilizing intermolecular hydrogen-bonding interactions stands for an effective approach in advancing the efficiency and stability of small-molecule acceptors (SMAs) for polymer solar cells. Herein, we synthesized three SMAs (Qo1, Qo2, and Qo3) using indeno[1,2-b]quinoxalin-11-one (Qox) as the electron-deficient group, with the incorporation of a methylation strategy. Through crystallographic analysis, it is observed that two Qox-based methylated acceptors (Qo2 and Qo3) exhibit multiple hydrogen bond-assisted 3D network transport structures, in contrast to the 2D transport structure observed in gem-dichlorinated counterpart (Qo4). Notably, Qo2 exhibits multiple and stronger hydrogen-bonding interactions compared with Qo3. Consequently, PM6 : Qo2 device realizes the highest power conversion efficiency (PCE) of 18.4 %, surpassing the efficiencies of devices based on Qo1 (15.8 %), Qo3 (16.7 %), and Qo4 (2.4 %). This remarkable PCE in PM6 : Qo2 device can be primarily ascribed to the enhanced donor-acceptor miscibility, more favorable medium structure, and more efficient charge transfer and collection behavior. Moreover, the PM6 : Qo2 device demonstrates exceptional thermal stability, retaining 82.8 % of its initial PCE after undergoing annealing at 65 °C for 250 hours. Our research showcases that precise methylation, particularly targeting the formation of intermolecular hydrogen-bonding interactions to tune crystal packing patterns, represents a promising strategy in the molecular design of efficient and stable SMAs.

Precise Methylation Yields Acceptor with Hydrogen‐Bonding Network for High‐Efficiency and Thermally Stable Polymer Solar Cells

AbstractUtilizing intermolecular hydrogen‐bonding interactions stands for an effective approach in advancing the efficiency and stability of small‐molecule acceptors (SMAs) for polymer solar cells. Herein, we synthesized three SMAs (Qo1, Qo2, and Qo3) using indeno[1,2‐b]quinoxalin‐11‐one (Qox) as the electron‐deficient group, with the incorporation of a methylation strategy. Through crystallographic analysis, it is observed that two Qox‐based methylated acceptors (Qo2 and Qo3) exhibit multiple hydrogen bond‐assisted 3D network transport structures, in contrast to the 2D transport structure observed in gem‐dichlorinated counterpart (Qo4). Notably, Qo2 exhibits multiple and stronger hydrogen‐bonding interactions compared with Qo3.

Clientelism and its Influence in the Nepali Press

This review explores the clientelist structure in politics and its influence in Nepali media with two aims: first, to identify how the clientelist structure has been practiced and influenced media in Nepal; second, to identify how the media perform the functions of clientelist networks. This review uses desk research of post 1990 documents focusing on the practices of clientelist structure in personalized behavior of the leaders, volatile political culture, fragmented civic society, and mounting corruption index in Nepal. Clientelism was a widely practiced phenomenon and it weakened the ideological base of the political parties and became the causes of uncertainty in Nepali politics. The unstable politics decreased public trust and reputation of the politicians, and visibility became a major concern to the leaders while reaching out to the electorate. In this context, the media became a vital tool to communicate with the public for political goals. The power holders practice clientelism, appointing loyalties in the board of directors in the state-owned media, attempt to endorse press restricted bills, and distribute welfare advertisements and subsidies to the favorable media. The media owners practice clientelism, recruiting professionals with strong political ties, frequently changing editors and journalists to ensure balanced representation of different political connections. The journalists tend to establish political connections and cover news with limited ethical guidelines with reference to their allies and advocate the political strategies of their patronage. Besides political intervention, the shrinking economy in the limited media market, long history of political parallelism of the press and the strong presence of the role of the state might be the explanation for adopting clientelist networks in the media.

Exploration The Candidates of Xenobiotic Degrading Indigenous Bacteria from Probolinggo City Landfill by Using Next Generation Sequencing (NGS)

Soil bacteria from tropical environments play a significant role in resolving various environmental issues, including biodegradation. Exploratory research on biodiversity is crucial to develop and harness the potential of different types of soil bacteria that are highly abundant. The bacterial diversity in landfills is typically high due to the decomposition of organic and inorganic waste, creating a favorable medium for the growth and development of soil bacteria. This study aims to assess the candidates of xenobiotic degrading indigenous bacteria from the Probolinggo City landfill using Next Generation Sequencing (NGS) method. The research stages include: 1) sampling, 2) isolation of genomic DNA from samples using the ZymoBIOMICS DNA MiniPrep Kit from Zymo Research, 3) amplification of isolated DNA with primers 16S 27F – 1429R, 4) sequencing the results of DNA amplification with NGS, 5) downstream analysis of the results using software Pavian Krona Tools, and 6) narrative analysis review to identify the candidates of xenobiotic degrading indigenous bacteria. The results show that soil samples from the Probolinggo City landfill exhibited a high diversity of bacterial communities. Based on NGS analysis, 2400 bacterial species were identified, comprising 56 genera, 17 orders, 4 classes, and 4 phyla, with respective abundances of Proteobacteria (70%), Firmicutes (15%), Planctomycetes (2%), and Cyanobacteria (0,3%). Based on the narrative analysis review, several bacteria in the Probolinggo City landfill exhibited potential as: 1) polypropylene-degrading bacteria, including Bacillus cereus, B. licheniformis and B. thuringiensis. 2) styrofoam degrading bacteria, namely Bacillus amyloliquefaciens, Bacillus cereus, Bacillus firmus and Pseudomonas aeruginosa. 3) total ammonia nitrogen (TAN) reducing bacteria, including Bacillus megaterium. 4) pesticide degrading bacteria Profenofos and Chlorantraniliprole, including Bacillus stearothermophilus. and 5) tannic acid degrading bacteria, including Pantoea dispersa. These results indicate that the Probolinggo City landfill is a good habitat for various xenobiotic-degrading bacteria, then the isolation of specific bacteria can be designed using an appropriate selective medium.

The Emotional Expression of Ink Language in Chinese paintingA Case Study of the Ink Art of Bada Shanren

Ink art holds a distinctive position within the realm of artistic expression in China. Throughout the course of Chinese history, ink painting has served as the favored medium for literati to convey their deepest emotions. Unlike the blue-green ShanShui style, ink painting offers a material that is both of superior quality and cost-effective. It encompasses techniques such as ink color changes, rubbing, and dyeing, allowing artists to directly reflect their pursuit of poetic expression. Bada Shanren, also known as Zhu Da, emerges as a preeminent master of ink painting during the early Qing Dynasty, whose artistic legacy continues to evoke profound thoughts and emotions even in contemporary times. By delving into the historical context and techniques employed in ink painting, this article explores the profound emotional expressions prevalent in literati ink art, using Bada Shanren as a compelling case study.

MICROBIOMES OF HUMAN, LIVESTOCK ANIMAL GASTROINTESTINAL TRACTS AND OF FOOD PRODUCTS AND COMPOUND FEEDS: CONNECTIONS AND IMPACTS. PART 1

The physiological mechanisms of food digestion in humans and feed digestion in animals are determined by the structure of the gastrointestinal tract (GIT) and diet. Accordingly, humans are omnivores, while domestic animals are divided into ruminants, monogastric herbivores, and monogastric omnivores, and birds are divided into herbivores (geese, ducks) and omnivores (chickens, turkeys, etc.). The digestion and assimilation of food and feed depends not only on own mechanisms but also on the GIT microbiome. The location of the most important part of this microbiome and its composition depend on the species: in ruminants, it is the rumen microbiome, in horses – the cecum (it is a counterpart of the rumen), in humans and pigs – the intestine, in birds – the crop, gizzard and cecum. These microbiomes are in constant close connection with the host organism, and this connection is realized through numerous molecular mechanisms of interaction between bacterial cells and host cells and tissues. GIT microorganisms not only help to assimilate food (feed) by partially digesting it, but also secrete biologically active substances that have protective, stimulating and other beneficial effects for the host. In adult hosts, this GIT microbiota is well developed and stable, while in children and young animals it can be much more mobile and vulnerable. Food and feed contain many components that are a favorable medium for the development of microorganisms. Raw materials and components of animal origin are the most contaminated, while vegetable raw materials and components, as well as premixes, contain significantly fewer microorganisms. Among the microorganisms colonizing raw materials, food and feeds, coliforms, salmonellae and molds may be present. In young animals, the feed microbiota ingested into the GIT, even without taking into account obligate or opportunistic pathogens, can cause shifts or changes in the digestive microenvironment towards deterioration, which will have a corresponding impact on the efficiency of feed absorption and, through it, on the efficiency of feeding and animal productivity.

The Addition of a High Concentration of Phosphorus Reduces the Diversity of Arbuscular Mycorrhizal Fungi in Temperate Agroecosystems

Phosphorus (P) is an essential macronutrient crucial for both plant growth and crop production, playing a pivotal role in agriculture since the early 20th century. The symbiotic relationship between AMF and plants serves as a classic illustration. These fungi play a regulatory role in the growth and development of plants, especially in facilitating the absorption of P and carbon molecules by plants. While there has been a growing body of research on the community assembly of arbuscular mycorrhizal fungi (AMF) in recent decades, our knowledge of the processes governing the coexistence of these AMF communities influenced by P in agroecosystems remains limited. To investigate the impact of various P fertilizers on AMF communities in temperate agroecosystems, this study was conducted using soils sourced from wheat–maize rotation farmland at Henan Agricultural University Yuanyang Base. With the Illumina MiSeq high-throughput sequencing technique, we systematically examined the taxonomic composition of soil AMF at the Yuanyang Base of Henan Agricultural University in a wheat–maize rotation agricultural field. Our primary objective was to unravel the mechanisms behind AMF community assembly and stability under varying P gradient fertilization conditions. Nonmetric Multidimensional Scaling (NMDS) analysis revealed significant differences among AMF communities in field soil subjected to various treatments (p < 0.05). A torus translations test demonstrated positive associations with the three treatments in 36 out of the 51 examined AMF operational taxonomic units (OTUs), making up 70.59% (p < 0.05) of the results. Furthermore, 37.84% (14/37) of the OTUs displayed preferences for the low P concentration treatment, while 34.29% (12/35) and 32.26% (10/31) favored medium and high P concentrations, respectively. An analysis of the Normalized Stochasticity Ratio (NST) and Checkerboard Score (C-score) indicated that in temperate agroecosystems, deterministic processes predominantly governed AMF in all treatment groups, with high P conditions exerting a stronger influence than low or medium P conditions. This study underscores the profound impact of long-term P fertilizer application on AMF community structures within temperate agricultural systems employing wheat–maize rotation. Additionally, it highlights the dominant role played by deterministic processes in shaping the assembly of AMF communities in these temperate agricultural systems that use P fertilizers. These findings emphasize the need for balanced nutrient management, particularly concerning P, to ensure the stability of AMF communities.

Study of Optimal Conditions to Grow Thai Ganoderma, Fruiting Test, Proximate and Their Alpha Glucosidase Inhibitory Activity.

Ganoderma (Ganodermataceae) has a worldwide distribution and has been widely used in traditional medicines. In this study, we report wild strains of Ganoderma that include two G. sichuanense and one G. orbiforme from northern Thailand. Optimal conditions for mycelium growth were ensured. The most favourable medium was potato sucrose agar for G. sichuanense and oatmeal agar for G. orbiforme and at 25 °C and 30 °C and pH 4-8. All types of cereal grains can be used to promote the growth of the mycelia of Ganoderma species. Fruiting tests were performed. All strains of Ganoderma produce fruiting bodies successfully in bag culture at 28 ± 1 °C with 75-85% relative humidity. Only G. orbiforme produced fruiting bodies in field cultivation at the laboratory scale. In the first flush yields, the G. sichuanense strain MFLUCC 22-0064 gave better production (the B.E was 152.35 ± 6.98 g). This study is the first to document the bag and field cultivation of wild Thai G. orbiforme. Ganoderma species are revealed to contain high amounts of fiber (47.90-52.45% d.b.), protein (12.80-14.67% d.b.), fat (4.90-5.70% d.b.), and carbohydrates (3.16-4.02% d.b.). Additionally, G. sichuanense and G. orbiforme were preliminarily screened for biological activity for inhibition of alpha-glucosidase enzyme activity. The IC50 values of G. orbiforme (MFLUCC 22-0066) was 105.97 ± 1.36 µg/mL and G. sichuanense (MFLUCC 22-0064) was 126.94 ± 0.87 µg/mL. Both strains had better inhibition than acarbose (168.18 ± 0.89 µM). These results on wild strains of Ganoderma will be useful for further studies on the applications of Ganoderma. Later the species can be introduced to domestic markets for cultivation and medicinal use.

Cheese Fermented with Human-Derived Limosilactobacillus reuteri DSM 17938 and Mushroom Powders: A Novel Psychobiotic Food with Enhanced Bioactivity and Sensory Acceptability

Fermented foods containing psychobiotics are of growing interest among food scientists. Human-derived Limosilactobacillus reuteri DSM 17938, a gut symbiont and potential psychobiotic strain, has been shown to exhibit the following health benefits: anti-inflammation and GABA-production capacity, as well as modulation of pathogen and cancer cell growth. The aim of this research was to develop an acid-coagulated fresh soft quark-type cheese, fermented with L. reuteri DSM 17938, with enhanced bioactivity, sensory acceptability, and overall likeability. Psychobiotic-containing cheeses represent the food of a new generation, so it is of great importance to gain the trust of the consumers. To develop a familiar taste, cheese samples were enriched with mushroom powders of Agaricus bisporus and Pleurotus ostreatus. A high abundance of lactic acid bacteria was maintained in all cheese samples (>log 7.64 CFU/mL), while cheese extracts exhibited cytotoxicity to colon cancer cell line HCT116 (up to 30.96%) in vitro. Additionally, cheese samples provided a favorable medium for the growth of the probiotic Escherichia coli Nissle 1917 (>log 7.11 CFU/mL). Sensory evaluation revealed high scores for all samples (up to 97.21% of maximum overall quality). The survey conducted in this study offered insights into consumer willingness to try products containing psychobiotics. This study demonstrates the potential for the successful development of fermented food products with L. reuteri DSM 17938, which exhibits all the desired traits that consumers may receive well. Further research is required to explore the potential health benefits of these innovative food products.

Evaluation of foam application in providing required conditioning for EPB hard rock TBMs

AbstractUtilizing the earth pressure balancing technique on hard rock tunnel boring machines (TBMs) is an efficient way to overcome engineering geological hazards that disrupt the application of these machines. Considering that geomechanical and engineering geological conditions of soil and rock are dramatically different, proposing a suitable conditioning design for earth pressure balance (EPB) hard rock TBMs requires particular attention to the characteristics of the excavated material and ground conditions. In this paper, foam application providing a favourable support medium for EPB hard rock TBMs is evaluated based on the experience of the Tehran metro line 6 southern expansion sector project, using laboratory and actual data. TBM muck, with different water contents, was used as the test specimen after granulometry correction. The trend of changes in the workability of foam conditioned mix was obtained by performing 350 slump tests. The pressurized permeability cell test (PPCT), a testing device capable of applying high water pressures to the conditioned material, was used to evaluate the impermeability of workable mixes. Results indicate that although foam can efficiently increase the workability of dry and moistened specimens, the presence of a separated liquid phase in the test specimen disrupts its application; moreover, foam conditioned mix is permeable even against low water pressures.

Paeonia peregrina Mill Petals as a New Source of Biologically Active Compounds: Chemical Characterization and Skin Regeneration Effects of the Extracts.

Paeonia peregrina Mill. is a perennial herbaceous plant species, known for the medicinal value of all of its plant parts, although the chemical composition of the petals is unknown. This study aimed to determine the chemical fingerprint of the petals and also establish the optimal extraction parameters, extraction medium, and extraction method for petals collected from different localities in Serbia. The optimization was performed in order to acquire extracts that are rich in the contents of total polyphenol content (TPC) and total flavonoid content (TFC), and also exhibit strong antioxidant activity. In addition, the influence of the extracts on several human skin pathogens was evaluated, as well as their ability to aid wound closure and act as anti-inflammatory agents. Both the extraction medium and the applied technique significantly influenced the skin-beneficial biological activities, while methanol proved to be a more favorable extraction medium. In conclusion, the extraction conditions that yielded the extract with the richest phenolic content with satisfactory biological potential varied between the assays, while the most promising locality in Serbia for the collection of P. peregrina petals was Pančevo (South Banat).

The Movement Against Democratic Backsliding in Israel

The movement against democratic backsliding in Israel was perhaps the most powerful social movement that Israel has seen, spanning over 3 months. It is credited with halting the right‐wing coalition's anti‐democratic constitutional and judicial reforms. The paper analyzes and highlights key factors in the origins, protest, and outcome stages of the movement. The movement is interesting in how experiences and personal challenges of negative emotions were addressed and overcome by protesting. The movement is also marked by a strategy that helped separate local protest initiatives to coalesce into national disruption events. The most effective forms of pressure are analyzed: resistance headquarters, direct pressures on politicians, pressures by army veteran volunteers, the public involvement of experts, favorable media coverage, and pressures from international players. The movement's impact on stopping the legislation and turning public opinion against the government coalition is finally observed, alongside suggestions for future research.

Medium- to Long-term Results of Nonanatomic Spring Ligament Reconstruction Using an Allograft Tendon in Progressive Collapsing Foot Deformity With Severe Abduction Deformity.

Spring ligament reconstruction (SLR) has been suggested as an adjunct to other reconstructive procedures to potentially avoid talonavicular joint fusion in progressive collapsing foot deformity (PCFD) with severe abduction deformity. Most clinical reports present short-term follow-up data and a small number of patients. The purpose of this study was to examine the medium- to long-term outcomes of an SLR using allograft tendon augmentation as part of PCFD surgical reconstruction. This study to our knowledge represents the largest number of patients and the longest follow-up to date. This study retrospectively reviewed 26 patients (27 feet, mean age of 61.4 years) who underwent SLR with allograft tendon as part of PCFD reconstruction. The mean follow-up of the cohort was 8 years (range, 5-13.4). Radiographic evaluation consisted of 5 parameters including talonavicular coverage angle (TNC), with the maintenance of correction being evaluated by comparing parameters from the early postoperative period (mean: 11.6 months, range, 8-17) to final follow-up. Foot and Ankle Outcome Score (FAOS) and patient satisfaction questionnaires were collected at final follow-up. Conversion to talonavicular or subtalar fusion was considered as a failure. Final radiographs demonstrated successful abduction correction, with the mean TNC improving from 43.7 degrees preoperatively to 14.1 degrees postoperatively (P < .0001). All other radiographic parameters improved significantly and exhibited maintenance of the correction. All FAOS subscales showed significant improvement. Responses to the satisfaction questionnaire were received from all except 1 patient, of whom 88.5% (23/26) were satisfied with the results, 96.2% (25/26) would undergo the surgery again, and 88.5% (23/26) would recommend the surgery. Eight feet (29.6%) required painful hardware removal and 1 (3.7%) developed nonunion of the lateral column lengthening osteotomy. No patient required conversion to talonavicular or subtalar fusion. This study demonstrates favorable medium- to long-term outcomes following PCFD reconstruction including an SLR with allograft tendon augmentation. Level IV, case series.
