Management Control Systems and Sustainability: A Bibliometric Analysis
Authors: Quesado Patrícia , Silva Rui , Oliveira Helena Costa
Published: June 2024

Including social and environmental concerns in decision-making processes and business operations is essential for organizations. Management control systems are crucial in integrating sustainability issues into decision-making processes. Thus, this study aims to analyze international publications about the relationship between management control systems and sustainability, identifying trends in evolution and future research opportunities. Based on bibliometric techniques, the outputs obtained in the Web of Science (n = 139) and Scopus (n = 73) databases were analyzed in the bibliometrix R package to map and systematically review the literature. After removing duplicates, we obtained a final output of 157 articles. The analysis of these publications draws attention to the relevance and emergence of these topics in academic and business circles and concludes that this area of knowledge has gained relevance in the last five years of research. The originality of this study lies in its ability to offer valuable insights that can shape future research agendas. By focusing specifically on how management control systems support or hinder sustainability initiatives, the study fills a gap in existing literature, which often treats these subjects separately. Future research can focus on the challenges of integrating sustainability into accounting frameworks and the role of technology in accounting for sustainability. The continuous study of these topics is essential to enable professionals and organizations to face contemporary challenges, ensure ethics and transparency, promote sustainability and responsibility, and ensure long-term success in a world increasingly aware of environmental and social issues.

This paper focuses on an integrated approach to study the materials and the degradation issues in the urban mural painting Ama Il Tuo Sogno, painted by the famous street artist Jorit Agoch in Matera (Italy). The study was conducted in the framework of a conservation project, aiming to contrast a progressive decay affecting the artifact that started a few months after its creation. Multi-analytical techniques were used to investigate the stratigraphy and chemical composition of the pictorial film within a low-impact analytical protocol for sustainable diagnostics. They included polarized light microscopy in UV and VIS reflected light, FTIR spectroscopy, Py-GC-HRAMS, and SEM-EDS. The mineralogical–petrographic composition of the mortar employed in the pictorial support was also studied with optical microscopy of thin sections and X-ray diffractometry. To know the mechanism underlying the degradation, IR thermography was performed in situ to establish the waterways and the distribution of the humidity in the mural painting. In addition, ion chromatography and X-ray diffractometry were used to identify and quantify the soluble salts and to understand their sources. The overall results allowed us to determine the chemical composition of the binder and pigments within the pictorial layers, the mineralogical–petrographic characteristics of the mortar of the support, and the execution technique of the painting. They also highlighted a correlation between the presence of humidity in the painted mural and the salt damage. The mineralogical phases were detected in the mural materials by XRD, and the results of ion chromatographic analyses suggested a supply of soluble salts mainly from the mortar of the support. Finally, the study provided basic knowledge for planning appropriate sustainable conservation measures.
El Niño’s Implications for the Victoria Falls Resort and Tourism Economy in the Era of Climate Change
Authors: Dube Kaitano
Published: June 2024

Scientists agree that as global temperatures rise, the intensity of the El Niño–Southern Oscillation (ENSO) phenomenon also increases. In southern Africa, El Niño events often cause severe droughts that adversely affect a region’s gross domestic product (GDP). However, the impact of El Niño on the tourism industry in this area has not been studied sufficiently. This study examines how frequently El Niño events occur and their consequences on the Victoria Falls resort. It specifically focuses on the potential implications for the regional tourism economy during the 2023–2024 El Niño event. This study critically analyses potential strategies for tourism businesses to enhance their resilience in light of the increasing intensity of El Niño events in the region. Using the Niño 3.4 index, it has been determined that there have been at least four extreme El Niño events since 1980: 1983, 1998, and 2016, and most recently, in 2023/24. Analysis of the Standardized Precipitation Index (SPI) and hydrological data from the Victoria Falls hydrological station showed that El Niño events significantly affect water flows at Victoria Falls, negatively impacting the resort’s reputation and brand. Examination of tourism statistics reveals that drought often leads to a decline in tourism, negatively affecting tourist resort towns’ economies. Given the projected record-low water levels for late 2024, this study recommends implementing improved communication and marketing strategies that highlight low-water activities and other non-water-dependent tourism offerings at the resort to ensure the resilience of the tourism economy. There is an urgent need to promote resorts as year-round destinations to support the climate-resilient tourism sector.
Public Benefits Valuation of Dynamic Green Roof Stormwater Retention
Authors: Cook Jessica , Huh Yunsun , Winden Matthew
Published: June 2024

This study evaluates the public benefits associated with different green roof systems to manage stormwater runoff in Milwaukee, Wisconsin. An internet-based stated-preference conjoint choice experiment was administered to residents of Milwaukee to ascertain the public benefits value of different potential green roof infrastructure programs. This study contributes to the literature on the public benefits of green roofs in two ways. First, this study examined the perceived value of dynamic stormwater retention facilitated using “smart” green roofs with access to real-time weather data versus traditional extensive green roofs. Second, a wider range of public benefits associated with green roofs, including improved water quality, air quality, biodiversity, and urban heat island effects, were estimated. Estimation of these public benefits allows for determination of the optimal public policy for supporting green roofs as a component of decentralized stormwater management in municipalities.
Study on Neutrosophic Graph with Application on Earthquake Response Center in Japan
Authors: AL-Omeri Wadei Faris , Kaviyarasu M.
Published: June 2024

A mathematical method of combining several elements has emerged in recent times, providing a more comprehensive approach. Adhering to the foregoing mathematical methodology, we fuse two extremely potent methods, namely graph theory and neutrosophic sets, and present the concept of neutrosophic graphs (ℵG). Next, we outline many ideas, such as union, join, and composition of ℵGs, which facilitate the straightforward manipulation of ℵGs in decision-making scenarios. We provide a few scenarios to clarify these activities. The homomorphisms of ℵGs are also described. Lastly, understanding neutrosophic graphs and how Japan responds to earthquakes can help develop more resilient and adaptable disaster management plans, which can eventually save lives and lessen the effects of seismic disasters. With the support of using an absolute score function value, Hokkaido (H) and Saitama (SA) were the optimized locations. Because of its location in the Pacific Ring of Fire, Japan is vulnerable to regular earthquakes. As such, it is critical to customize reaction plans to the unique difficulties and features of Japan’s seismic activity. Examining neutrosophic graphs within the framework of earthquake response centers might offer valuable perspectives on tailoring and enhancing response tactics, particularly for Japan’s requirements.
Positive Inotropic Agents in Cancer Therapy: Exploring Potential Anti-Tumor Effects
Authors: Ribeiro Eduarda , Vale Nuno
Published: June 2024

Cancer remains a significant global health challenge despite advancements in diagnosis and treatment. Traditional cancer therapies often face limitations such as toxicity and drug resistance. Drug repurposing has emerged as a promising strategy to overcome these challenges by identifying new therapeutic uses for existing drugs. This review explores the potential of repurposing positive inotropic agents, which are traditionally used in cardiovascular medicine, for cancer therapy. Positive inotropic agents, including cardiac glycosides, β-agonists, phosphodiesterase inhibitors, and calcium sensitizers have shown preclinical evidence of anti-tumor activity through various mechanisms, such as modulation of the intracellular signaling pathways, increasing cyclic adenosine monophosphate (cAMP) levels, the production of nitric oxide, and decreasing reactive oxygen species levels. Despite the absence of specific clinical trials in this area, these findings suggest a promising avenue for further research and development of combination therapies to improve cancer treatment outcomes. However, challenges such as elucidating specific anti-tumor mechanisms, identifying predictive biomarkers, and optimizing safety profiles need to be addressed to fully realize the therapeutic potential of positive inotropic agents in oncology.

Published: June 2024

Excessive cadmium (Cd) in rice is a global environmental problem. Therefore, reducing Cd content in rice is of great significance for ensuring food security and human health. A field experiment was conducted to study the effects of foliar application of citric acid (CA) on Cd absorption and transportation in rice under high Cd-contaminated soils (2.04 mg·kg−1). This study revealed that there was a negative correlation between Cd content in vegetative organs and CA content, and that foliar spraying of CA (1 mM and 5 mM) significantly increased CA content and reduced Cd content in vegetative organs. The Cd reduction effect of 5 mM CA was better than that of 1 mM, and 5 mM CA reduced Cd content in grains and spikes by 52% and 37%, respectively. CA significantly increased Mn content in vegetative organs and increased Ca/Mn ratios in spikes, flag leaves, and roots. CA significantly reduced soluble Cd content in vegetative organs and promoted the transformation of Cd into insoluble Cd, thus inhibiting the transport of Cd from vegetative organs to grains. The foliar field application of 1 mM and 5 mM CA could inhibit Cd absorption and transportation by reducing Cd bioactivity and increasing the antagonistic of essential elements in rice vegetative organs. These results provide technical support and a theoretical basis for solving the problem of excessive Cd in rice.
Phylogenetic Tracing of Evolutionarily Conserved Zonula Occludens Toxin Reveals a “High Value” Vaccine Candidate Specific for Treating Multi-Strain Pseudomonas aeruginosa Infections
Authors: Benyamini Payam
Published: June 2024

Extensively drug-resistant Pseudomonas aeruginosa infections are emerging as a significant threat associated with adverse patient outcomes. Due to this organism’s inherent properties of developing antibiotic resistance, we sought to investigate alternative strategies such as identifying “high value” antigens for immunotherapy-based purposes. Through extensive database mining, we discovered that numerous Gram-negative bacterial (GNB) genomes, many of which are known multidrug-resistant (MDR) pathogens, including P. aeruginosa, horizontally acquired the evolutionarily conserved gene encoding Zonula occludens toxin (Zot) with a substantial degree of homology. The toxin’s genomic footprint among so many different GNB stresses its evolutionary importance. By employing in silico techniques such as proteomic-based phylogenetic tracing, in conjunction with comparative structural modeling, we discovered a highly conserved intermembrane associated stretch of 70 amino acids shared among all the GNB strains analyzed. The characterization of our newly identified antigen reveals it to be a “high value” vaccine candidate specific for P. aeruginosa. This newly identified antigen harbors multiple non-overlapping B- and T-cell epitopes exhibiting very high binding affinities and can adopt identical tertiary structures among the least genetically homologous P. aeruginosa strains. Taken together, using proteomic-driven reverse vaccinology techniques, we identified multiple “high value” vaccine candidates capable of eliciting a polarized immune response against all the P. aeruginosa genetic variants tested.
How to Overcome a Snail? Identification of Putative Neurotoxins of Snail-Feeding Firefly Larvae (Coleoptera: Lampyridae, Lampyris noctiluca)
Authors: Krämer Jonas , Hölker Patrick , Predel Reinhard
Published: June 2024

The larvae of some lampyrid beetles are highly specialized predators of snails. They have been observed to climb on the shells of their prey and use this exposed position to bite and inject secretions potentially originating from the midgut. Besides serving the purpose of extra-oral digestion (EOD), injected compounds also seem to have a paralyzing effect. Up to now, the toxins causing this paralyzing activity have not been identified. In the current study, we provide a first compositional analysis of the midgut secretion from lampyrid larvae, with a focus on identifying putative neurotoxins causing the observed paralyzing effect. For this purpose, we utilized a combined proteo-transcriptomic approach to characterize the compounds present in the midgut secretion of larval stages of Lampyris noctiluca. In terms of the absolute numbers of identified compounds, the midgut secretion is dominated by hydrolyzing enzymes comprising peptidases, carboxylesterases, and glycosidases. However, when considering expression levels, a few rather short cysteine-rich peptides exceed all other compounds. Some of these compounds show moderate similarity to putative neurotoxins identified in the venom of other arthropods and could be responsible for paralyzing effects. In addition to these potential toxins, we provide a list of peptides typical of the midgut secretion of L. noctiluca, supplemented by the corresponding precursor sequences.

Published: June 2024

Influenza A virus (IAV) infections in swine are usually subclinical, but they can reach high morbidity rates. The mortality rate is normally low. In this study, six vaccinated, spontaneously deceased sows revealed IAV infection and enhanced neutrophilic bronchopneumonia with unexpectedly large numbers of infiltrating eosinophils. The purpose of this study was to characterize these lung lesions with special emphasis on the phenotypes of inflammatory cells, the presence of eosinophilic peroxidase (EPO), and neutrophil extracellular traps (NETs). The number of Sirius red-stained eosinophils was significantly higher in the lungs of IAV-infected sows compared to healthy pigs, indicating a migration of eosinophils from blood vessels into the lung tissue stimulated by IAV infection. The detection of intra- and extracellular EPO in the lungs suggests its contribution to pulmonary damage. The presence of CD3+ T lymphocytes, CD20+ B lymphocytes, and Iba-1+ macrophages indicates the involvement of cell-mediated immune responses in disease progression. Furthermore, high numbers of myeloperoxidase-positive cells were detected. However, DNA-histone-1 complexes were reduced in IAV-infected sows, leading to the hypothesis that NETs are not formed in the IAV-infected sows. In conclusion, our findings in the lungs of IAV-infected vaccinated sows suggest the presence of so far unreported field cases of vaccine-associated enhanced respiratory disease.

Authors: Erickson Mauri , Boone Tyler J. , Nadworny Patricia L.
Published: June 2024

Pentasilver hexaoxoiodate (Ag5IO6) has broad-spectrum antimicrobial efficacy, including the long-term prevention of microbial adherence, the rapid killing of planktonic microorganisms, and the elimination of mature biofilms. This study’s goal was to determine whether it may also have antiviral activity against structurally distinct viruses. Ag5IO6 was tested following ASTM E1052-20, Standard Practice to Assess the Activity of Microbicides Against Viruses in Suspension, against adenovirus type 5, murine norovirus, poliovirus type 1, SARS-CoV-2 (original), and SARS-CoV-2 (omicron) (host cells: H1HeLa, RAW 264.7, LLC-MK2, Vero E6, and Vero E6, respectively). A 0.1 g/mL Ag5IO6 suspension was prepared and the viruses were exposed for 30 min, 4 h, or 24 h. Exposure to Ag5IO6 resulted in complete kill of SARS-CoV-2 (omicron) within 30 min, as well as complete kill of both SARS-CoV-2 (original) and the murine norovirus within 4 h. Ag5IO6 showed increasing activity over time against the adenovirus, but did not achieve a 3-log reduction within 24 h, and showed no antiviral activity against the poliovirus. These results demonstrate that Ag5IO6 has antiviral activity against medically important viruses, in addition to its well-characterized antimicrobial activity, suggesting that it may be valuable in situations where the prevention or simultaneous treatment of microbes and viruses are necessary.
Exploring Iguape Virus—A Lesser-Known Orthoflavivirus
Authors: Saivish Marielena V. , Nogueira Maurício L. , Rossi Shannan L. , Vasilakis Nikos
Published: June 2024

Brazil has earned the moniker “arbovirus hotspot”, providing an ideal breeding ground for a multitude of arboviruses thriving in various zoonotic and urban cycles. As the planet warms and vectors expand their habitat range, a nuanced understanding of lesser-known arboviruses and the factors that could drive their emergence becomes imperative. Among these viruses is the Iguape virus (IGUV), a member of the Orthoflavivirus aroaense species, which was first isolated in 1979 from a sentinel mouse in the municipality of Iguape, within the Vale do Ribeira region of São Paulo State. While evidence suggests that IGUV circulates among birds, wild rodents, marsupials, bats, and domestic birds, there is no information available on its pathogenesis in both humans and animals. The existing literature on IGUV spans decades, is outdated, and is often challenging to access. In this review, we have curated information from the known literature, clarifying its elusive nature and investigating the factors that may influence its emergence. As an orthoflavivirus, IGUV poses a potential threat, which demands our attention and vigilance, considering the serious outbreaks that the Zika virus, another neglected orthoflavivirus, has unleashed in the recent past.

Published: June 2024

This prospective study investigated the ultrasonographic appearance of the canine testis from birth to adulthood. Eight purpose-bred laboratory Beagle-breed dogs were monitored from 4 to 40 weeks of life. The following parameters were evaluated every two weeks: bodyweight and height, scrotal and testicular volume, ultrasonographically measured testicular volume, echogenicity, heterogeneity, blood-flow score, ratio of the grayscale intensity value of the testis to the capsule, ejaculate volume, motility, viability, and number of spermatozoa. A correlation analysis was carried out between the various measurements obtained. Fertility was achieved in the 36th week of life. The echogenicity of the testicular parenchyma increased with age, and subsequently to the 30th week of life remained constant. The heterogeneity of the testicular parenchyma, as was evaluated by the standard deviation of the values of grayscale intensity of the parenchyma, also increased with age and was >19 at the onset of fertility. The ratio of grayscale intensity of testicular parenchyma had values < 200 at maturity. A colour Doppler evaluation first detected blood flow in the testis in the 22nd week. After the 32nd week, distinct signals were visible. In the 36th week, >80% of the testes imaged had visible vessels. A significant correlation was found between all the evaluation methods. The findings of the study may help clinicians detect the onset of fertility in dogs, especially when semen evaluation is not feasible; however, their applicability in all breeds or individuals might possibly vary due to genetic, physiological, and developmental differences. In summary, the study ultrasonographically explores the testicular maturity in dogs, with the aim to improve clinical assessments and health management in these animals.
Degradation of Atrazine by Flow-Through UV-Based Advanced Oxidation Processes: Roles of Light Source and Chlorine Addition

Published: June 2024

Understanding the degradation kinetics and mechanisms of trace organic contaminants (TrOCs) by UV-based advanced oxidation processes (UV-AOPs) are pivotal in realizing their efficient application in water treatment. However, the relevant knowledge in practical flow-through reactors remains a void, compared with that of commonly used batch reactors. To fill the knowledge gaps, the current work investigated the degradation of atrazine (ATZ) in flow-through UV-AOP systems with different light sources and chlorine additions. The results showed that UV/Cl2 in the reactors (with a diameter of 50 mm) was not very efficient in ATZ degradation while the pseudo-first order degradation rate constant was elevated by over 2.7 times with vacuum UV (VUV)/UV. In contrast to observations in the batch reactors, the addition of chlorine to the flow-through VUV/UV system unexpectedly decreased the rate constant by about 39%. The analysis of the relative contributions of different degradation pathways revealed that the inhibitory effect of the chlorine addition arose from the transformation of HO• to reactive chlorine species (e.g., ClO•) which had low reaction rate constants with ATZ. The baffle implementation promoted the ATZ degradation by 12–58%, mainly due to an enhanced mixing that facilitated the radical oxidation. The energy costs of the UV-AOPs in ATZ removal ranged within 0.40–1.11 kWh m−3 order−1. The findings of this work are helpful in guiding efficient VUV/UV and VUV/UV/Cl2 processes in drinking water treatment.

PRINCIPLES OF ARCHITECTURAL DESIGN OF MODERN FARMERS' MARKETS
Authors: Zhang Furui
Published: June 2024

The object of the study is modern farmers' markets. It is important to note that due to changes in social and economic conditions, the architectural organization, namely the architectural and artistic image, spatial and functional planning solutions, of modern market complexes has undergone major changes. The development of modern markets is characterized by a variety of architectural solutions and differs greatly from traditional ones. In this regard, the definition of the principles of the architectural organization of modern farmers' markets is of great importance now and in the future. The purpose of the study is to determine the basic principles of the architectural organization of modern farmers' markets. To achieve this goal, an analysis of domestic and foreign experience in the design and construction of modern farmers' markets was carried out. Research methods: the study of scientific, literary and journalistic sources and statistical data (including Internet sources) revealing the issues of the development of the architecture of the farmers’ market; the study of design, graphic and photographic materials characterizing the domestic and foreign practice of design and construction of the farmers’ market. As a result of the research, the following principles of forming the architecture of modern farmers' markets have been identified: the principle of universality, the principle of sustainability, the principle of gastronomy, the principle of openness and the principle of identity. These principles show that modern farmers' markets play an important role in the sustainable development of cities, stimulating the viability of public spaces
Figurative graphic expressions and the first Western Mediterranean farmers: a new zoomorphic contribution from Southern France
Authors: López-Montalvo Esther , Manen Claire , Guilaine Jean , Baleux François , Convertini Fabien
Published: June 2024

In Europe, the emergence of the agro-pastoral way of life is accompanied of a novel socio-symbolic system that develops new forms of expression, themes and supports. In this sense, the shape, themes and decorative patterns in ceramics have particularly favoured the characterisation of both regional identities and spheres of influence at different temporal and geographic scales. Among the themes portrayed, the figurative motifs take on special relevance since they also invoke a symbolic sphere that underlies the complex spread of farming from the Near East into Europe. Bearing this in mind, we present the first figurative zoomorphic decoration identified on pottery from the beginning of the Neolithic in Mediterranean France. Although these depictions are well known in Italy and Spain, they were still unheard of in our country. The analysed vase comes from the coastal site of La Corrège (Leucate, Aude), discovered in the 1970s following dredging operations. New radiocarbon dates place this site in the period of full development of the cardial complex in southern France and Mediterranean Spain, between 5300 and 5000 cal. BCE. The three-dimensional reconstruction of the decorated vessel and the microscopic observation of technical gestures, allowed us to virtually replace the motifs on the graphic space provided by the body of the vase, and thus to reproduce the spatial and narrative structure of the decoration. The in-depth analysis of the motifs and spatial patterns allows us to determine the order of the lines and the sequence of execution of the decoration, to interpret this decoration as the representation of a wild animal, probably a wild boar if we consider certain distinctive anatomical features of this species, and to deduce a narrative dimension.

This figurative ornamentation also provides new arguments regarding both the highly diversified means and forms of symbolic expression accompany the Neolithic transition in this area, and the fact that systematic opposition between schematic graphic expression and naturalist expression does not seem to be relevant. In this context, the characterization of the diversity of the graphic expressions of the first farmers’ communities is an important challenge for future research. The study of graphic traditions and their large-scale distribution can thus provide new arguments for the analysis of the spatial and temporal dynamics of Mediterranean Neolithisation, while at the same time promoting our understanding of the symbolic system of the first farming societies, as the driving force of their identity and social

cohesion.

Les sépultures et dépôts humains présentés dans cet article ont été découverts sur le site de la Cavalade au sud de Montpellier (Hérault). Il s’agit d’une vaste occupation domestique essentiellement datée du Néolithique final dont seules les structures excavées les plus profondes étaient conservées. Le site, qui a été fouillé par l’Inrap en 2013 sur une surface de presque 3 ha, a livré dix sépultures ou dépôts recelant dix-huit individus, ainsi qu’une grande sépulture collective (Mas Rouge) qui ne sera pas présentée ici. Les dix sépultures, qui se répartissent dans une échelle temporelle comprise entre 3100 et 2650 cal. BC en deux phases principales, sont donc le plus souvent individuelles mais aussi plurielles dans quatre cas. L’une d’entre elle a livré six individus inhumés simultanément et recèle des indices qui plaident pour une procédure dite «d’accompagnement » . Par ailleurs, les résultats de violences ont été mis en évidence sur des ossements pour d’autres individus, ajoutant de nouveaux éléments aux débats sur les modalités de certaines prises en charge sépulcrales au regard des statuts individuels des inhumés. Cette réflexion s’enrichit aussi de données anthropobiologiques et isotopiques très informatives ainsi que de données sur des mobiliers intégrés aux dépôts, outils lithiques et parures au statut particulier.
Les vents du Grand Nord soufflent-ils jusqu’aux Tropiques ? Une réponse à Y. A. Gómez Coutouly, 2021
Authors: Lourdeau Antoine
Published: June 2024

Dans un récent article paru dans le Bulletin de la Société préhistorique française (2021, no 118-2), Yan Axel Gómez Coutouly présente une relecture critique d’une partie des publications portant sur les sites pléistocènes d’Amérique antérieurs à 20 000 ans. Il se focalise principalement sur la région connue sous le nom de Serra da Capivara, dans le Nord-Est du Brésil. À partir des données à sa disposition, il conclut à l’absence de preuve démontrant l’existence d’occupations humaines aussi anciennes. La présente réponse ne vise pas à discuter les conclusions de Y. A. G. Coutouly et étoffer ainsi une littérature déjà très (trop ?) prolixe sur les controverses relatives aux origines des premiers Américains. Elle a pour objectif de relever de nombreuses imprécisions ou erreurs rencontrées au long du texte. J’ai retenu quatre points de discussion : les confusions toponymiques et leurs conséquences, la surinterprétation des résultats d’études éthologiques sur les singes Sapajus libidinosus de la région, les failles dans les représentations graphiques présentées dans cet article et les oublis et erreurs dans la description des sites archéologiques. Tout en rétablissant auprès des lecteurs une vision plus proche de la réalité des données disponibles sur les sites archéologiques de la Serra da Capivara, je mets en évidence l’existence de biais dans le raisonnement de Y. A. G. Coutouly, en contradiction avec l’approche scientifique objective qu’il revendique.

La lechuga (Lactuca sativa L.) es una hortaliza de hoja que en México genera un importante ingreso económico; sin embargo, los altos niveles de nitratos (NO3-)  pueden ocasionar problemas de salud, ya que generan compuestos carcinogénicos. Una alternativa para disminuir el NO3- en hojas es sustituyéndolo por amonio (NH4+), lo que podría beneficiar la salud humana reduciendo la ingesta de NO3-. El objetivo del presente estudio fue evaluar el crecimiento y acumulación de NO3- en lechuga con diferentes relaciones de NO3-/NH4+ en la solución nutritiva en dos estaciones de cultivo. Las lechugas se cultivaron en un sistema hidropónico de raíz flotante. El diseño experimental fue completamente al azar en arreglo factorial 4 × 2, cuatro relaciones de NO3-/NH4+ (100/0, 80/20, 65/35 y 50/50) y dos estaciones de cultivo (verano y otoño), con un total de 8 tratamientos. Las variables evaluadas fueron peso seco de raíz (PSR), de hojas (PSH) y total (PST), área foliar (AF) y concentración de NO3- en peciolo. No se encontraron diferencias significativas entre estaciones para PSH, PST y AF. En otoño el PSR aumentó 11 % en comparación con el de verano. En verano el contenido de NO3- en peciolos aumentó 55 % comparado con el de otoño. La relación 100/0 aumentó 25 % el PSH, PST y AF, y 15 % más de NO3- en peciolo. Durante el verano, utilizando una relación 100/0 se presentó un aumento de 4 % en el PSH, PST y AF. Al usar NH4+ en las relaciones 65/35 y 50/50 se redujo 25 % el crecimiento y 15 % la acumulación de NO3- en peciolo. En la estación de verano la aplicación de 100/0 en plantas de lechuga aumentó el crecimiento. En la estación de verano el contenido de NO3- en peciolo aumentó el doble.

En México existe una creciente demanda de maíz (Zea mays L.) de grano amarillo que se emplea como materia prima del sector agropecuario e industrial; su consumo ascendió a 15.3 millones de toneladas en el año 2016 (FIRA, 2016). Gran parte de esta demanda se concentra en las regiones del centro y occidente del país, donde existen importantes cuencas lecheras y numerosas granjas porcícolas y avícolas. En esas regiones, el maíz de grano amarillo, que se utiliza en la elaboración de alimentos balanceados, suma el 76 % de la demanda y el resto se emplea en procesos industriales (FIRA, 2016). Debido a lo anterior, las áreas subtropicales productoras de maíz desempeñan un papel estratégico para abastecer a las regiones de mayor demanda. En los últimos años México importó el 80 % de la demanda total de maíz de grano amarillo, que en 2016 fue de 12.2 millones de toneladas (FIRA, 2016); esto repercute en la balanza comercial y compromete la seguridad alimentaria del país.

El biocarbón es un material sólido poroso que se produce por la conversión termoquímica de materiales orgánicos en un ambiente limitado o en ausencia de oxígeno; tiene propiedades físico-químicas aptas para el almacenamiento a largo plazo de carbono y, potencialmente, mejora la fertilidad de los suelos. El objetivo del presente estudio fue evaluar la concentración nutrimental en biocarbón elaborado con cascarilla de arroz (Oryza sativa L.) y adicionado con ácido cítrico, maleico y propiónico al 5 y 10 % como catalizadores. El biocarbón se elaboró con la técnica de carbonización hidrotérmica a 200 ºC durante 19 h. Se determinó el rendimiento de biocarbón, concentración de materia orgánica y de N, P, K, Ca, Mg, Cu, Fe, Mn, Zn, Si y Na. Los mayores rendimientos de biocarbón (66 %) se obtuvieron cuando se añadieron los ácidos maleico y cítrico al 10 %. El mayor contenido de materia orgánica (71 %) se obtuvo con ácido maleico al 5 %. En general, los tres macronutrimentos con mayor concentración (mg kg-1) fueron Ca (4386-10,988), N (3067- 4467) y K (327-3530), mientras que los micronutrimentos con mayor concentración (mg kg-1) fueron Fe (77.1-238.3) y Mn (75.4-281.4), así como el elemento benéfico Na (92.8-160.0). Por sus características de rendimiento, concentraciones de materia orgánica y nutrimental, el biocarbón de cascarilla de arroz potencialmente se podría usar como mejorador de suelos agrícolas.

La semilla de tomate de cáscara (Physalis ixocarpa Brot. ex Horm.) que se usa en México en general es de baja calidad física, fisiológica y genética. Para producir semilla de alta calidad es necesario contar con variedades mejoradas y tecnología adecuada para su producción y beneficio. Se compararon dos máquinas para la extracción de semilla (molino eléctrico y despulpadora) con el objetivo de estudiar su eficiencia y efecto sobre el rendimiento y calidad de semilla de cuatro variedades mejoradas de tomate de cáscara (Diamante, Tecozautla 04, Gema y Manzano Tepetlixpa). La investigación se llevó a cabo en Chapingo, Estado de México, de julio a octubre de 2013, con un arreglo de tratamientos factorial 2 × 4, bajo un diseño experimental completamente al azar con cuatro repeticiones. Se extrajo y benefició la semilla de 1000 kg de fruto por unidad experimental. Se evaluó el tiempo total del proceso de extracción, rendimiento de materia prima (semilla sin beneficio), peso de semilla seca clasificada por tamaño (chica, estándar y grande), contenido de humedad de la materia prima en tres etapas del proceso de secado y germinación de semilla en cuatro etapas del proceso de beneficio. Se obtuvo el menor tiempo total de proceso y el mayor rendimiento de semilla con la máquina despulpadora. Con ambas máquinas se obtuvo la misma calidad fisiológica de la semilla. Las variedades evaluadas produjeron semilla de calidad fisiológica similar, aunque con diferente rendimiento de semilla. Existe interacción significativa entre máquinas y variedades para rendimiento de materia prima y de semilla beneficiada, al igual que para germinación.

Para proponer el mejor método de mejoramiento genético de una población es indispensable conocer sus parámetros genéticos y la variación genética que en ella existe. El objetivo de este estudio fue identificar los efectos genéticos, así como los posibles efectos maternos que actúan sobre algunos componentes nutrimentales y bioactivos del grano de maíz (Zea mays L.) en cruzas simples formadas a partir de cinco líneas endogámicas S6-S8. Las cruzas fueron desarrolladas para sistemas de producción en condiciones de riego y se evaluaron en Montecillo, Texcoco, Estado de México durante el ciclo de producción primavera-verano 2014. Con el grano de la F1 de las cruzas y de los progenitores se realizó el análisis genético del contenido total de aceite, proteína, almidón, cenizas y ácido fítico. Los resultados mostraron mayor variación para la aptitud combinatoria específica (ACE) que para la aptitud combinatoria general (ACG) en cada uno de los componentes nutrimentales; la ACE y ACG representaron, en promedio, 53 y 12 %, respectivamente, de la variación entre los genotipos, por lo que los efectos genéticos no aditivos (dominancia y epistasis) prevalecieron sobre los aditivos (ACG) entre los genotipos evaluados. Los efectos maternos y recíprocos mostraron diferencias significativas (P ≤ 0.01) para todas las variables, excepto para contenido de almidón. Se definió el comportamiento de los progenitores y de sus cruzas para dirigir el aprovechamiento eficiente de las características evaluadas. Algunas cruzas fueron superiores a sus progenitores en el contenido de los componentes bioquímicos, pero es necesario considerar la dirección del cruzamiento, dados los efectos maternos significativos encontrados en los componentes del grano.

Las terapias que inhiben la virulencia se han propuesto como una nueva alternativa para combatir infecciones bacterianas debido a que no generan resistencia. Los fenoles de cadena larga producidos por especies de la familia Anacardiaceae estructuralmente son muy diversos y se encuentran en forma de mezclas complejas. El objetivo de esta investigación fue analizar el potencial anti-percepción de quórum de mezclas de fenoles de cadena larga (MFCL) aisladas de dos especies vegetales de importancia etnomedicinal y comercial. Los MFCL se aislaron de la corteza de Amphipterygium adstringens (MFCLAa) y del pericarpo de la nuez de Anacardium occidentale (MFCLAo) con un rendimiento de 0.01 % de cera para MFCLAa y 3.24 % de aceite para MFCLAo. Se identificaron los ácidos anacárdicos como los principales constituyentes mediante espectroscopía de infrarrojo y cromatografía líquida de alta resolución acoplada a espectrometría de masas. En MFCLAa se identificaron las cadenas monoinsaturadas y saturadas de 15 a 19 átomos de carbono C19:1 (41 %) y 15:0 (19.8 %) como las más abundantes. MFCLAo presentó principalmente los compuestos de naturaleza polinsaturada y de cadena de 15 carbonos 15:3 (40 %) y 15:2 (24 %). Ambas mezclas redujeron de manera significativa la producción del pigmento violaceina en el sistema modelo de Chromobacterium violaceum, lo que evidencia una actividad inhibidora de la percepción del quórum. Los dos MFCL evaluados tienen potencial para ser empleados en el desarrollo de terapias de antivirulencia, pero la de A. occidentale tiene la ventaja de producir los compuestos con un mayor rendimiento.

Мета даного дослідження. Експериментальне обґрунтування профілактики захворювань тканин пародонту за допомогою сорбенту та комплексу препаратів. Матеріал та методи дослідження. Були проведені експериментальні дослідження, в процесі яких оцінювали на щурах за допомогою моделі перекисного пародонтиту зміни біохімічних показників щелеп щурів під дією лікувально-профілактичних заходів, розроблених для пацієнтів із різним ступенем ураження тканин пародонту. В експерименті були використані 32 двомісячних щурів лінії Вістар стадного розведення. Щури були розділені на групи по 8 шт. в кожній. Статистично значущу відмінність між альтернативними кількісними ознаками з розподілом, відповідним нормальному закону, оцінювали за допомогою t-критерію Стьюдента. Результати свідчать про те, що моделювання перекисного пародонтиту у щурів шляхом додавання у корм переокисленої олії сприяло підвищенню ступеня атрофії альвеолярного відростку нижньої щелепи тварин, зниженню інтенсивності процесів кісткоутворення та інтенсифікації процесів резорбції, підвищенню активності маркеру руйнування органічної частини кісткової тканини у альвеолярній кістці, індукувало розвиток системного запалення. Профілактичне застосування лікувально-профілактичного комплексу попереджувало порушення у кістковій тканині альвеолярного відростку. Висновки. Моделювання перекисного пародонтиту у щурів шляхом додавання у корм переокисленої олії сприяло підвищенню ступеня атрофії альвеолярного відростку нижньої щелепи тварин, зниженню інтенсивності процесів кісткоутворення та інтенсифікації процесів резорбції, підвищенню активності маркеру руйнування органічної частини кісткової тканини у альвеолярній кістці, індукувало розвиток системного запалення. Додаткове введення щурам з пародонтитом лікувально-профілактичного комплексу сприяло більш вираженої пародонтопротекторної ефективності: ступень атрофії альвеолярного відростку був нижчим ніж у інтактних тварин, показники ремоделювання кісткової тканини щелеп відповідали нормальним значенням.

High-quality unintentionally doped (UID) (001) β-Ga2O3 homoepitaxial films were grown on native substrates through metalorganic CVD. The surface parallel grooves were repaired under low temperature and pressure conditions, reaching the surface roughness of 2.22 nm and the high electron mobility of 74.6 cm2/Vs. Enhancement-mode MOSFETs were fabricated on the UID β-Ga2O3 film, showing a positive turn-on threshold gate voltage of 4.2 V and a breakdown voltage of 673 V. These results can serve as a reference for (001)-oriented lateral Ga2O3 power transistors and may contribute to the development of Ga2O3 power devices.

Sığır paratüberkülozu (PTB) sığırların granulomatoz gastroenteritle karakterize kronik seytirli, bulaşıcı, zoonoz bir hastalığıdır. Süt sığırcılığı sektöründe önemli ekonomik kayıplara sebep olmakla birlikte zoonotik karakterli olması insanlarda görülen Chron’s hastalığının temelini oluşturabilme olasılığını düşündürmektedir. Bu çalışmada paratuberküloz hastalığının Ege Bölgesi’nde yetiştirilen süt sığırlarındaki seroprevalansının belirlenmesi amaçlanmıştır. 2022 yılı içerisinde İzmir, Muğla, Denizli, Aydın, Kütahya ve Uşak illerinden tesadüfi örnekleme ile seçilip Bornova Veteriner Kontrol Enstitüsü’ne gönderilen 2 yaşından büyük aşılanmamış süt sığırlarına ait 1000 adet kan serumu üzerinde çalışılmıştır. Bu amaçla diğer tanı yöntemlerinden avantajlı olduğu belirlenen ELISA yöntemi kullanılmıştır. Çalışma materyalinin ELISA ile incelenmesi sonucunda toplamda 84 (%8,4) örnek pozitif; 28 (%2,8) örnek şüpheli bulundu. 888 (%88,8) serum örneği ise negatif olarak tespit edildi. Elde edilen veriler ışığında serumlarda seropozitifliğin görülmesi hastalığın bölgede halen varlığını koruduğunu, koruma, kontrol ve eradikasyon yöntemlerinin belirlenerek uygulanmasının gerekli olduğunu düşündürmektedir.
