The present paper shows how the development of synthetic nanostructured biomaterials, such as multisubstituted hydroxyapatite (msHAP) with Mg2+, Zn2+ and Sr2+ ions is important and beneficial at the same time for the normal functioning of the body. Moreover, the paper discusses a broad topic of major importance in orthopedic and dental surgery, namely the incorporation of msHAP into the polymeric matrix of poly lactic acid (PLA). This composite is used in order to cover the surface of the titanium implant in order to obtain bone integration and heal bone fractures. The review also highlights the importance of improving silver nanoparticle (SNPs) coating in order to combat postoperative infections. Through such approaches, medicine has managed to evolve considerably, and the contributions brought by great personalities and young researchers in the field have increased its area of applicability.

Influence on storage condition and time on properties of carbonated beverages from utilization of polyethylene terephthalate (PET) bottles: chemometric and health risk assessment
Authors: Omokpariola Daniel Omeodisemi
Published: July 2022

The effect of storage condition (room temperature and sunlight exposure) of eight carbonated beverages sold in Nigeria were assessed over a period of 15 weeks of storage time. Properties such as antimony (Sb) leaching, pH, acidity, specific gravity (S.G.) and total soluble solid content (TSSC) were analyzed using appropriate instrument and methodology at three weeks interval respectively. The concentration of Sb determined ranged from 0.001-0.011 mg/L and 0.001-0.0015 mg/L for room temperature and sunlight exposure. pH was between 2.82-4.81 and 2.82-4.82. TSSC were 0-14 O brix and 0-14.96 O brix. Acidity were 0.025-0.19 and 0.025-0.34. Specific gravity was 0.9921-1.052 and 0.9921-1.0577. The result shows that pH decreased with time as Sb, TSSC, acidity and S.G. increased with time thereby influencing significance (p<0.05). Difference in Sb amounts shows that sunlight exposure had more impacts compared to room temperature as storage time increased. TSSC values increased steadily leading to hydrolysis of sugar and other chemical ingredients, thus affecting the specific gravity. Acidity impacted by increased reactivity from carbon dioxide present, which reduces pH of the drink. Chemometric assessment such as contamination factor and pollution load index indicate low concentration and no pollution associated. Factor analysis conducted showed that all parameters and storage time were positively interrelated except for pH due to side reaction. Cumulative variance showed high variance (>50). Health risk assessment conducted for adults and children showed that Tolerable Dose Index and Hazard Index were below one, thus indicates no adverse health impact as the values were relatively higher in children compared to adults. Prolong consumption of carbonated drinks stored longer than expected can cause fatigue and headaches on a short-term basis, and weight loss and diabetes on a long run especially in children. Regular parental monitoring is advised to mitigate health impact for children.

Authors: Muñoz Sergio Segundo González , Vara Ignacio Arturo Domínguez , Gastelum José Luis Bórquez , Rodríguez Juan Manuel Pinos , Bribiesca Jacinto Efrén Ramírez , Gutiérrez Daniel Trujillo
Published: July 2022

Background: The use of silages from non-conventional sources of nitrogen and soluble carbohydrates in feeding lambs is controversial in terms of nutrient supply; due to the minimum number of studies reported to date of in vitro evaluations that allow measuring its nutritional value in ruminants. Objective: To evaluate the additive effect and fermentation potential of silages plus concentrates in diets for lambs on the in vitro gas production kinetics. Methodology: Six diets (silage + concentrate) were evaluated in a factorial arrangement of 3 N sources (dried poultry litter, fresh swine manure, agricultural urea) × 2 carbohydrate sources (sugar cane molasses, bakery by-product). The diets contained: a) silage (400 g/kg DM) and b) concentrates (600 g/kg DM) based on soybean meal, ground corn, wheat bran, corn stover, fish meal, and vitamin and mineral premix. Average gas production data were analyzed with PROC MIXED and the gas production curves were fitted into the Exponential Logistic model with PROC NLMIXED. Results: The PO+MC (151.87 mL/gas MS) and CF+MC (153.12 mL/gas MS) treatments had higher average gas production during incubation. An additive effect was observed on the maximum asymptote of gas production in the CF+MC (+ 4.26%) and PO+MC (+ 3.75%) diets (P<0.01). Diets based on PO or CF combined with MC and SPP had higher IVDMD, IVOMD, and IVNDFD than the control treatment (UR). Implications: The inclusion in diets for growing lambs of corn stover silage based on rapidly fermentable carbohydrate sources with non-protein nitrogen from pig and poultry excreta in diets for growing lambs has associative effects on nutrient degradability and its fermentation potential in small ruminant feed. Conclusions: The PO+MC treatment has a higher potential for gas production due to the associative effect of its components.

Authors: Romero Cortes Teresa , Pérez España Victor Hugo , Peralta Gil Martin , Aparicio Burgos José Esteban , Cuervo Parra Jaime Alioscha
Published: July 2022

Background. Wild teosintle populations represent an important source for the increase of the genetic variability of the native corn of Mexico and Central America. Teosintle plants have a great tolerance to climatic variation and grow in a wide range of altitude; despite this, it is a plant genetic resource that is scarcely valued and therefore little studied. Objective. Morphologically characterize and make a phenological evaluation of accessions of Mexican wild teosintle from CIMMYT. Methodology. An experimental design of complete random blocks with three repetitions and plots of 4 rows of 2 m long with a separation between rows of 80 cm and a planting density adjusted to a hectare of 15,000 plants was used. Results. The Chalco and Mesa Central races of Zea mays ssp. mexicana were those that demonstrated the best values for the agronomic performance variables studied amongst of all the teosintle treatments evaluated. Implications. With the knowledge generated, it will be possible to establish management strategies for wild teosintle populations for commercial purposes. Conclusion. Based on the results obtained, the Chalco and Mesa Central races could be considered to increase genetic variability in genetic improvement programs of commercial corn, as food for farm animals and/or humans and in plant germplasm conservation programs.

Published: July 2022

Background. Climate change puts pressure on the agroecosystems, and the cultivation of Coffea arabica may not be resilient under these conditions. Objective. The objective of this study was to determine the impact of climate change on coffee agroecosystem resilience. Methodology. Maxent software was applied to model current and future scenarios. The current scenario was developed using 19 bioclimatic variables obtained from the Worldclim database with climate records for the period 1960-1990. As for the future scenario, the impact of climate change was modeled based on climate projections for the year 2050 using 3 different global climate models: CCCMA, HADCM3, and CSIRO. The variables in this study were analyzed using Statistica and Gephi software. Results. The results showed under the climate change scenario that 15% of the plots were distributed in unsuitable / non-resilient areas and 85% in moderately suitable and suitable/resilient areas for the establishment of C. arabica. Also, the adaptation indicators showed a higher frequency (30) of negative values in coffee agroecosystem (C-AES) plots in areas of both high impact and low impact. Implications. The data could allow the redesign of the coffee agroecosystems to improve the weak elements of its structure. Even the structure reinforcement could be direct with farmers or by public politics, government institutions, organizations, and coffee businessmen. Conclusion. It was concluded that after 2050, the conditions for coffee cultivation will be reduced and as a consequence, the proportion of plots at lower altitudes will remain outside the optimal environmental conditions. On the other hand, there will be plots within the area with suitable conditions for cultivating C. arabica, therefore these will be resilient to climate change, but these will need to establish precise adaptation strategies for the disturbances that will take place in the immediate future.

Morphology and Semantics of Conjuncts: The Case of MA Theses in the Philippine Setting
Authors: Jennifier T. Diamante
Published: July 2022

This study explores the morphology and semantics of conjuncts as characterized in the introduction sections of 42 Master of Arts (MA) thesis manuscripts from various tertiary institutions in the Philippines. The data were analyzed employing the seven categories of conjuncts proposed by Quirk et al. (1985). The manual analysis was complemented by a concordance software known as Antconc. Results revealed that, morphologically, one-word conjuncts were widely employed in the data over their phrasal counterparts. Semantically, conjuncts conveying a high degree of formality were used predominantly while those exemplifying conversational tones were variably utilized in the data. Findings further disclosed the ubiquity of concessive conjuncts and the scant presence of inferential conjuncts in the data indicating their discourse and semantic roles in the concerned research section. Conclusions drawn from the results yield pedagogical implications to English language teaching derived particularly on the usage and non-usage of conjuncts reflected in the MA dissertation texts.
Storm, Stress, and Solastalgia: Climate Change in the Undergraduate Literature Classroom
Authors: Kirsten Møllegaard
Published: July 2022

Climate change has become a major force in shaping human experience. Climate change affects not only the Earth's atmosphere, biospheres, glaciers, and oceans; it also affects our perception of humanity's role in the natural world. While the majority of the grand narratives on climate change is in the hands of scientists, the literary humanities have an important role to play in creating a forum in the English literature classroom for students to read fiction that stimulates critical thinking about climate change, its contexts and history, and the future. This paper examines literary trends that creatively explore and cope with the effects of climate change on society. While several literary genres directly address climate change, this paper will contextualize two examples of climate science fiction - Paulo Bacigalupi's The Water Knife and Octavia Butler's Parable of the Sower – with William Shakespeare's King Lear, Charlotte Brontë's Wuthering Heights, and Mary Shelley's The Last Man. These works address solastalgia, a neologism that describes profound sadness and frustration about irreversible changes to one's home environment and the feeling of powerlessness. Similar to the influential Sturm und Drang (storm and stress) movement in Romantic literature, today's environmental distress and human worries are reflected in genres like science fiction. Climate change fiction enables readers to process alarmist contemporary environmental issues by contextualizing the anxiety-inducing data generated by scientific research with the power of the human imagination and the emotional intelligence of reading fiction.
Lexical Features of When in Manila Blogs: IPE Word-Formation Processes and their Acceptability to ESL Teachers
Authors: Carlo B. Afable  , Harold Nilo M. Austria  , Joan D. Evidente
Published: July 2022

The impact of internet in the 21st century has significantly influenced the variety of English language through the innovations in electronic communication. Human communication became faster, more dynamic, and convenient in the digital world. The profound effect of this change is evident in the idiosyncratic usage of words in the sharing and exchange of information online. This study focuses on the lexical creativity of Internet Philippine English (IPE) neologism or the process of creating new words and its acceptability for English as a Second Language (ESL) teachers. A corpus of 300,000+ words was collected from “When In Manila” blogs from 2017-2019 and processed using AntConc 2 software. Findings showed twenty-three IPE lexical items formed through normal expansion, shortening, coinage, and borrowing based on Dimaculangan and Gustilo’s (2018) framework of word-formation processes in Philippine English. Five of these words were frequently occurring among the different categories of the blogs. Moreover, the words were evaluated by ESL teachers to validate their acceptability vis-a-vis academic Philippine English. Thus, it was revealed that these words are only acceptable in informal and conversational English levels. Further, the pedagogical implications entail reviewing the present curriculum and assess where new changes and developments in PE can be incorporated into academic instruction.
Use of Task-Based Activities in Improving Active Listening Comprehension Skills of Grade 8 ESL Students
Authors: Renee Julia D. Blancaflor  , Margarita Ines I. Mauleon  , Jeanne F. Purpura
Published: July 2022

Listening is a core receptive skill that facilitates language acquisition and proficiency, yet it is often neglected in the teaching and learning process. This research was conducted to investigate if there was any significant difference in the participants’ active listening comprehension skills before and after the implementation of the task-based activities anchored on the social learning theory. To achieve the research objectives, thirty 32 participants, 17 males, and 15 females were selected to participate and take the pre-and post-tests for Grades 9-10 adapted from the English Language Proficiency Assessments for California (ELPAC). Surveys, focus group discussions, and interviews were also conducted to identify and monitor any improvement in the participants’ active listening comprehension competencies. The quantitative results and analysis showed no significant difference in the pre-and post-tests. However, other findings indicate an important improvement in the participant’s behaviour as manifested in the FGD and interviews. This further implies that effective implementation of the SLT through TBAs could help language learners improve their active listening comprehension skills. English teachers may consider integrating real-life contexts in their classroom tasks to intensify dynamic and collaborative interactions using language-based instructions.
Lexico-morphosemantic and Structural Variation and Change of Mandaya Courtrship and Marriage Rituals
Authors: Alfel E. Obguia
Published: July 2022

The purpose of this study was to determine the lexico-morphosemantic and structural variations and changes of Mandaya courtship and marriage rituals in the past and the present time. It sought the reasons for the variations and changes of the rituals of the Mandaya people on this phenomenon against their culture, ethnic identity, and hopes and aspirations in preserving their culture. The study employed an ethnographic qualitative research design with 25 participants involved in an in-depth interview and focus group discussion. The study revealed variations and changes in the lexico-morphosemantics and structures of the courtship and marriage rituals then and now. The lexico-morphosemantic variations and changes were evidenced by affixation, reduplication, deletion, and loan words. The structure of marriage rituals evolved from three major segments to eight segments in the present time. The courtship rituals were not practiced anymore at present. There were three major themes that emerged on the reasons and variations of the rituals, namely language stance, exposure to other languages and religious denominations, and contemporary social indicators. The variations and changes were attributed to religion, migration, intermarriage, and social media influence.

Authors: Cielo May Urbano  , Ma. Angelica Gumangan  , Leah Gustilo, Ph.D.  , Ma. Pamela A. Capacete
Published: July 2022

The present study sought to determine the current skills, competencies, and needs of the Senior High School (SHS) students in a public school in Metro Manila, Philippines, regarding academic reading and writing through needs analysis (NA). The NA uses two approaches: (1) present situation analysis (PSA), with a purpose of pointing out the English proficiency of students and their level in reading and writing in the second language at the onset of the course (Dudley-Evans & St Johns, 1998; Robinson, 1991 as cited in Ibrahim, 2016), and (2) learning needs analysis (LNA), which is referred to as, “what the learner needs to do to learn” (Hutchinson & Waters, 1987 as cited in Ibrahim, 2016, p.2). The researchers conducted a survey among 100 SHS students and triangulated the results through an item analysis of Reading and Writing diagnostic test administered to the participants and interview sessions with three English teachers, seven diagnostic test high scorers, and seven students with low scores. For reading, researchers identified these skills to be the main struggles of SHS students: (1) recognizing different patterns of development (comparison and contrast, definition, description, narration, etc.) in texts; (2) evaluating the coherence, organization, grammar, and mechanics of a text; (3) having poor vocabulary knowledge; and (4) identifying ways on how to select and organize information. For writing, the main challenges are (1) lack of topic-relevant background knowledge and topic-specific paper on texts, (2) insufficient knowledge and practice on writing with proper citation, (3) incorrect grammar, (4) shallow vocabulary, and (5) use of different patterns of development when writing. The present study recommends explicit instruction, utilization of text-based approach, and inclusion of authentic and collaborative tasks in teaching Reading and Writing in SHS in the Philippines.
“I Speak Not”: Accounts of English Language Learners With Glossophobia
Authors: Hasper Jay R. Santos  , Fhajema M. Kunso
Published: July 2022

This qualitative research employed the phenomenological method of study to determine the experiences of English language learners in public speaking and their coping mechanisms to redress such experiences. The study utilized in-depth interviews to elicit responses from the participants. Colaizzi’s data analysis method was used to analyze the data gathered. This study's participants were the ten selected and assessed Grade 12 students of a tertiary school located in Midsayap, North Cotabato. Results revealed that English language learners’ public speaking anxiety stemmed from the fear of perception or negative evaluation, the influence of unpleasant experiences, and pressure from competitiveness. The participants used four coping mechanisms to cope with the anxiety and improve themselves in the process – remediation, positive thinking, teacher’s positive attitude, and peer seeking. The researchers concluded that public speaking anxiety stems from fear of being judged, negative experiences, and pressure from the different environmental factors. However, certain anxious persons can use the abovementioned coping mechanisms to reduce or improve their speaking skills.

Published: July 2022

Writing a thesis in a second language (L2) remains a considerable challenge. By drawing on the Appraisal Theory (Martin & White, 2005), this study explored the way students of St. John Bosco's College of Education engage with the academic discourse community in their undergraduate (diploma) project writing. The data comprised introduction and conclusion sections of thirty (30) purposively sampled project works. Engagement items in the project works were examined manually. The results revealed that expand engagement markers were more frequently used than contract engagement markers, that deny was the dominant type of contract engagement markers, and that acknowledge was the most favored subtype of the expand engagement markers. This study confirms that an engagement system is a key tool to help novice writers align authorial voices with readers, thereby achieving promotional and persuasive purposes. The findings are of potential interest to other novice research writers and their examiners in future project work writing and examinations.

There were questions about the reasons for the lack of English proficiency of Indian graduates inspite of their English education both in school and college. This research study attempted to explore how English is taught in schools and the various factors that impact the teaching-learning process in schools.
Metaphorical Analysis of Electoral Texts: The Case of Philippine and Taiwanese Online News Commentaries
Authors: Diamante Jennifier , Mabuan Romualdo
Published: July 2022

Drawing on contrastive rhetoric tradition, this paper analyzes the metaphorical expressions utilized in the online news commentaries about the 2016 presidential electoral issues of two Asian countries, the Philippines and Taiwan. Upon a close scrutiny of the data, results show that Filipino journalists tend to thrive on individualistic issues dealing with certain political candidates whereas Taiwanese news writers seem to focus more on collective issues relating to a group such as political party and matters pertaining to their country in general. The data further revealed that Philippine commentaries are longer, contain more word-types and metaphor-laden while Taiwanese articles are shorter, indirect, and loaded with direct quotations. Additionally, findings disclosed four dominant metaphorical themes describing the electoral campaign procedure of the two countries as: ‘straight campaign’, ‘dirty campaign’, ‘witchcraft campaign’ and ‘warlike campaign’. Finally, this study concludes that metaphorical choice reflects the writer’s cognitive and socio-political stance. Pedagogical implications are offered in the light of these findings.
Efficacy of Unguided Conversation on Fluency and Speaking Confidence: A Case Study in South Korea
Authors: Baldwin Jeffrey , Manning Jennifer , Powell Natasha , Martinez Paulina
Published: July 2022

To date, there is limited research into the measurable benefits of unguided and unstructured conversation practice (typically a popular, in-demand service) for adult English language learners. This project looks to determine the differences in measured oral fluency as well as self-reported speaking confidence of South Korean university students before and after several months of conversational English practice with native English instructors. Participants were given weekly one-on-one “free talk” sessions with no grammatical instruction and very limited corrective feedback for a total of one hour. Sessions were recorded at early and late program intervals in order to calculate the average length of runs and speech rate. Moreover, students completed pre- and post-program surveys to estimate their overall confidence levels in L2 speaking. This project found limited change in fluency without direct corrective feedback. Furthermore, our measurements of students’ self-reported speaking confidence revealed inconsistent trends from the first to last sessions. This research seems to indicate that loosely structured, “coffee shop” style lessons should adopt a more structured curriculum in order to see more pronounced and measurable growth over time.

Anlass ist der tragische Unfalltod von Silke Helfrich, um mit diesem Beitrag an ihr geistiges Erbe zu erinnern. Dies führt zwangsläufig zum Werk der ersten Nobelpreisträgerin für Wirtschaft, Elinor Ostrom. Diese zeigte früh Wege auf, wie soziale Gruppen selbstverantwortlich und effizient Gemeinschaftsressourcen bereitstellen, verwalten, nutzen und erhalten und leistete damit einen entscheidenden Beitrag für einen effektiven Umweltschutz von unten. Über Ostrom hinausgehend betrachtet Helfrich Prozesse des Commoning, die die Bereitstellung und Nutzung von Gemeingütern sicherstellen. Ihr Ziel ist die Überwindung des Denkens in Markt- und Staat-Alternativen, um einen gleichrangigen Bereich des solidarischen Wirtschaftens zu setzen. Die Nähe zu Formen genossenschaftlichen Wirtschaftens wird dargelegt.
Wirtschaft der Commons: Empirisches und historisch-utopisches Paradigma

Published: July 2022

Dieser Aufsatz rekonstruiert die utopische Wissenschaft und untersucht damit Commons. Utopische Forschung war und ist Bestandteil der Sozialwissenschaften und dynamisierte sich in Zeiten gesellschaftlicher Krise. Sie untersucht dabei die gesellschaftliche Verallgemeinerung von Keimformen neuen Wirtschaftens. Hierfür dürfen Commons nicht nur gütertheoretisch als kollektiv genutzte Ressourcen gedacht werden, sondern, wie in der sozialen Commonstheorie, auch als soziale Form, die Produktions- und Konsumtionsmittel angenommen haben und annehmen können. Der Aufsatz verbindet Commons mit Care und Reziprozität, stellt Elemente einer Commons-Utopie dar und verknüpft empirische und utopische Forschung.
Restoration of Soil Organic Carbon a Reliable Sustenance for a Healthy Ecosystem
Authors: Olusoji David Alabi
Published: July 2022

Agricultural sustainability is an indicator for economic prospect across the globe. The revolution of industrial development and the growth of annual crop to meet the need of increasing world population is a determining factor for SOC availability. Sustainability of agriculture is largely related to SOC and management practices. Agro-ecological stability is significant to soil type and fertility input. Organic matter is a combination of plant residue and/ or animal waste. This is capable of accumulating carbon and nitrogen in the soil. It retains water and support the buildup of organic carbon. It enhances the stability of SOC and crop yield. The use of organic matter is effective at stabilizing the microbial communities. Carbon sequestration is high with crops that have abundant residues. SOC can potentially mitigate climate change. It prevents the use of minimum and conventional tillage. Higher deposit of SOC is associated with crop yield. Perennial crop cultivation such as cup plant (Siliphium perforliatum. L.) can potentially sequestrate carbon into the soil than annual crop. SOC are often exhausted with the cultivation of annual crop such as maize. However, SOC can be retained by growing clover in between harvests and the next sowing. Mineral fertilizer can likewise accumulate SOC but not as efficient as the use organic manure and plant residue. Perennial crop was found useful at preventing environmental degradation and soil compaction. Consistent assessment of SOC is essential for continuous food production and plant growth. This can be achieved through a multidimensional software called multiple linear regression.

Authors: Ayalew Dereje , Abebe Bekele
Published: July 2022

The presented paper described in detail the mineralogy of silicic peralkaline eruptives from Kone volcano within the Ethiopian rift system, which is formed predominantly by rhyolite with some small occurrence of trachyte. The majority of eruptive rocks in the Kone volcanic area are phenocryst-poor. The studied rocks contain alkali feldspars (anorthoclase and sanidine), quartz, clinopyroxene (hedenbergite), aenigmatite and olivine (fayalite), accompanied by rare Fe-To oxides (ilmenite) and apatite. All these minerals are described in detail. These data are very interesting for all researchers, who study similar eruptive rocks.

Authors: Jate Melkamu , Lammel Joachim
Published: July 2022

The classical long-term trial at Hanninghof was established in 1958 on loamy sand soil in Duelmen, Germany to study the long-term effects of different nutrient management strategies. The impact of balanced mineral fertilizer application and integrating farmyard manure (FYM) with mineral fertilizer on indicators of sustainable crop production are evaluated in comparison to unbalanced nutrition. Crop rotation since 1958 was potato, followed by winter rye and oat. After 2008, the rotation was silage maize, winter rye, and potato to adjust the trial to current farm practice, but the treatments remained the same: a control plot without fertilizer; FYM alone; and mineral P + K, N, N + P, N + K, N + P + K, and N + P + K + Mg fertilizers with and without FYM. The effect of each treatment on crop yield, revenue, sustainable yield index, water and nutrient use efficiencies, soil nutrient and carbon contents, and soil pH are presented. Evaluation of the 62 years data shows that unbalanced nutrition caused by omitting nutrients and application of only FYM as organic nutrition reduced crop yield and revenue, led to inefficient use of resources and nutrients, and a depletion of soil fertility with negative implications on sustainability. Application of mineral fertilizer N + P + K + Mg as the balanced nutrition and supplementing FYM with mineral fertilizer as the integrated nutrition had social, economic and environmental benefits indicating sustainable crop production.

Among various abiotic stresses, water is reported as a rare entity in many parts of the world. Decreased frequency of precipitation and global temperature rise will further aggravate the situation in future. Being C4 plant, sugarcane requires generous water for the proper growth. Plant root system primarily supports above-ground growth by anchoring in the soil and facilitates water and nutrients uptake from the soil. The plasticity and dynamic nature of roots endow plants for the uptake of vital nutrients from the soil even under soil moisture conditions. In sugarcane, the major part of root system are generally observed in the upper soil layers, while limited water availability shifts the root growth towards the lower soil layer to sustained water uptake. In addition, root traits are directly related to physiological traits of the shoot to cope up with water limited situations via reduction in stomatal conductance and an upsurge in density and deep root traits, adaptations at biochemical and molecular level which includes osmotic adjustment and ROS detoxification. Under stressed conditions, these complex interactive systems adjust homeo-statically to minimize the adverse impacts of stress and sustain balanced metabolism. Therefore, the present chapter deals with physiological and biochemical traits along with root traits that helps for better productivity of sugarcane under water-limited conditions.

Published: July 2022

Quorum sensing is the cell to cell communication mechanism in microorganism through signalling molecules. Regulation of virulence factor, sporulation, proteolytic enzymes production, biofilm formation, auto-inducers, cell population density are key physiological process mediated through quorum-sensing (QS) signalling. Elevation of innate immune system and antibiotic tolerance of pathogens is highly increased with perspective of quorum-sensing (QS) activity. Development of novel drugs is highly attractive scenario against cell-cell communication of microbes. Design of synthetic drugs and natural compounds against QS signal molecules is vital combat system to attenuate microbial pathogenicity. Quorum sensing inhibitors (QSIs), quorum quenchers (QQs), efflux pump inhibitors (EPIs) act against multi-drug resistance strains (MDR) and other pathogenic microbes through regulation of auto-inducers and signal molecule with perceptive to growth arrest both in-vitro and in-vivo. QQs, QSIs and EPIs compounds has been validated with various animal models for high selection pressure on therapeutics arsenal against microbe’s growth inhibition. Promising QSI are phytochemicals and secondary metabolites includes polyacetylenes, alkaloids, polyphenols, terpenoids, quinones.

Pests are highly responsible for heavy crop losses and reduced food supplies, poorer quality of agricultural products, economic hardship for growers and processor. Generally, chemical control methods are practiced for their control which is neither always economical nor effective and may have associated unwanted health, safety and environmental risks. However, to meet the challenge of feeding to the ever increasing human population, an efficient, economical and environment friendly disease control methods are requisites. In this regard, biological control may be an effective means of reducing or mitigating the pests and pest effects through the use of natural enemies. Biological control is an environmentally sound which involves the use of beneficial microorganism to control plant pathogens and diseases they cause. Therefore, in this chapter we will provide a comprehensive account of this environmental friendly approach for effectively management of plant diseases. This chapter will also accentuate the development of biological control agents for practical applications and the underlying mechanism. The contents in the chapter will be beneficial and advantageous to all those working in academia or industry related to crop protection.

In order to maintain the balance with reactive oxygen species, the need for antioxidants is increasing. As for supplements to the conventional periodontal therapy, different antioxidants have been applied in an attempt to provide new possibilities in the periodontal treatment. This chapter focused on recent studies that used different antioxidants as adjuncts to conventional periodontal treatments.
Vector-Parasite Interactions and Malaria Transmission
Authors: Erhunse Nekpen , Okomayin Victor
Published: July 2022

Malaria remains one of the world’s most devastating vector-borne diseases. During the complex sexual development of the malaria parasite in the mosquito, it is faced with physical and physiological barriers which it must surmount before it can be transmitted to a human host. Proof-of-concept studies using RNAi have unearthed several parasite molecules which are important for countering the immunity of its vector. Understanding the counter-adaptations between the parasite and its vector could inform novel public health intervention strategies. For instance, it could guide the transgenic construction of resistant mosquitoes in which mosquito factors that restrict the parasite growth have been enhanced and/or factors promoting parasite growth deleted so as to make them refractory to malaria parasite infection. Such strategies, when deemed feasible, could be combined with conventional vector control methods as well as treatment of infection with effective malaria therapy, to actualize the malaria eradication goal.
Quality of Postharvest Degreened Citrus Fruit

Published: July 2022

External color is a key factor that defines external citrus fruit quality. Degreening with exogenous ethylene exposure is a widely used postharvest treatment applied to promote external citrus fruit color development, mainly with those cultivars that reach internal maturity while their external peel color is still green. Ethylene plays a crucial role in the color change of citrus fruit because it induces two simultaneous, but independent, processes—chlorophyll degradation and carotenoid synthesis. However, it is important to know, in addition to the effect on skin color development, whether this treatment can negatively affect other fruit quality parameters. This chapter addresses the influence of postharvest degreening treatment on the physicochemical, nutritional, and sensory quality of citrus fruit.

Published: July 2022

Skin substitutes have modernised burn wound reconstruction since their use was first pioneered by Burke and Yannas in the 1980s. Skin substitutes offer a solution to the problem of insufficient autologous skin graft availability in major burn wound closure. A growing body of evidence supports the role of skin substitutes in both acute major burns and secondary burn scar resurfacing. Classification of skin substitutes has become increasingly complex given the large variety of synthetic and biologic dermal matrices now available as the result of ongoing advances in regenerative medicine techniques. Classification systems are required to assist clinicians with selection and comparison of outcomes across a wide diversity of skin substitutes. Professor John Greenwood, invented, designed and developed one such dermal substitute, \'Biodegradable Temporising Matrix\', which is approved for use across the globe for reconstruction of major burns and complex wounds. This chapter provides a review of available classification systems for skin substitutes with a summary of the latest evidence in relation to their role and impact on burn wound outcomes. Future developments toward the elusive ‘ideal’ skin substitute may be possible through ongoing research efforts focused on clinical translation of modern skin tissue engineering techniques for burn wound reconstruction.
