The purpose of this research work is to determine the molecular identity of bacteria isolated from infected Zea maize using the 16s rRNA molecular sequencing protocol. The samples were obtained from Okeagbe, Akoko north-west local government in Ondo state with latitude and longitude of Okeagbe at 7.6450° N, and 5.7603° E respectively. Preparation of infected maize samples was cultured using the serial dilution method.. Confirmatory characterization of bacteria isolates using 16s rRNA (ribosomal RNA) sequencing procedures (purification, amplication, Sequencing, and DNA extraction) inclusive.The result shows the isolation of the bacteria isolates involved the culturing, inoculation, and plating of the isolate on a plated agar, the identification of the bacteria isolate includes the use of Gram staining, biochemical tests, and characterization using Bergey's manual and antibiotics Susceptibility Test. In Gram staining all bacteria isolates were positive except one, in the biochemical test most bacteria isolate was positive for sugar Fermentation and citrate test and all were negative for the Voges Proskauer test. In antibiotics Susceptibility test few were sensitive, most were susceptible to antibiotics used. With the use of the 16S rRNA and procedures (purification and application of product, Sequencing, and Extraction of DNA) the bacteria isolate were identified and characterized. The phylogenetic analysis and molecular identification of 16S rDNA sequencing revealed that Escherichia coli, Samonella enterica and Staphylococcus aureus were found to infect maize. Molecular characterization based on 16S rRNA Gene sequencing confirms the identity of bacteria. The conventional procedure shows the presence of different arrays of microorganisms in the infected maize, microbes identified are Bacillus subtilis, Bacillus anthracis, Micrococcus luteus, Clostridium sporogenes, Microbacterium lacticum, Clostridium sporogenes, Lactobacillus casei and Micrococcus luteus. The phylogenetic analysis and molecular identification of 16s rRNA sequencing revealed that Escherichia coli, Samonella enterica and Staphylococcus aureus were found to infect maize in Band fragment Base pair 1500bp. In conclusion, the hearsay that maize can only be infected by fungi, it was observed that the possibility of being infected with pathogenic bacteria is imminent. The bottom line is, there should be proper surveillance and food safety in our farm, market and food store, to prevent and totally eradicate emergence of pathogenic organism in our food item.

Published: July 2024

The problem of poverty in Indonesia is very complex which can trigger economic and socio-cultural problems, namely that there is a poor population of 9.36 percent. This indicates that prosperity has not been achieved in economic development in Indonesia. Ibnu Khaldun explained that a developed country is determined by the strength of the government implementing sharia and justice which is implicitly in accordance with the ideals of national development in Indonesia. The aim of this research is to analyze the actualization of Indonesia's economic development in terms of Ibnu Khaldun's thoughts. The research method used is qualitative library research sourced from secondary data using library research techniques from Muqaddimah books, journal articles and various kinds of relevant library materials which are then analyzed using descriptive analysis methods. The results of this research are that Indonesia's economic development has not yet achieved economic and socio-cultural balance as stated by Ibnu Khaldun. This is based on an imbalance between state revenues and government expenditure. The high taxes imposed on the public cannot yet be directly proportional to state spending which should be able to reduce inequality, poverty and so on, especially in underdeveloped areas.

Published: July 2024

BACKGROUND

Nine-valent human papillomavirus (9vHPV) vaccines can be administered in 2 doses 6 to 12 months apart in adolescents. The impact of extended dose intervals is unknown. We report immunogenicity and safety data in adolescents of a second 9vHPV vaccine dose administered ≥1 year after the first.

METHODS

This open-label safety and immunogenicity study (NCT04708041) assessed extended-interval 2-dose regimens of 9vHPV vaccine among adolescents (10 to 15 years) who received 2 9vHPV vaccine doses: the first ≥1 year before enrollment, and second, at enrollment (day 1). We measured serologic responses to vaccine-targeted human papillomavirus (HPV) types at enrollment day 1 (pre-dose 2) and 1 month post-dose 2 (month 1) using a competitive LuminexV® immunoassay. We estimated effects of dose interval on geometric mean titers (GMTs) using regression modeling. Participants reported adverse events (AEs) through 15 days after vaccination.

RESULTS

We enrolled 146 adolescents (mean age 13.3 years) with median 25 months since first 9vHPV vaccine dose (range: 12–53 months). Across vaccine-targeted HPV types, GMTs increased from day 1 to month 1; seropositivity at month 1 was 100%. Anti-HPV GMTs at month 1 were not affected by differences in dose interval of 12 to 53 months, based on regression modeling. The most common AEs were mild-to-moderate injection site reactions; no serious AEs were reported.

CONCLUSIONS

Extending the interval between first and second 9vHPV vaccine doses to 12 to 53 months did not affect antibody responses, with favorable safety profile. These results support feasibility of extended interval regimens for 9vHPV vaccine.
Dualidades en la novela De repente (1933) de Diego Muñoz Espinoza
Authors: Silva Contreras Macarena
Published: July 2024

En De repente (1933), novela del chileno Diego Muñoz Espinoza, la fragmentación mental del personaje principal funciona como una estrategia narrativa que permite evidenciar cómo él se construye a sí mismo a través de dos identidades en constante pugna. En la primera parte de este artículo se explora la dualidad del personaje en términos de su soledad existencial y de la fractura de su ‘yo’; en la segunda,  en términos de objetos, situaciones y personajes que también se hallan desdoblados; y, finalmente, en la duplicación del protagonista a través del recurso del humor y de la risa, elementos que lo llevan a la autocontemplación de sí y al reconocimiento de su miseria. Estas ideas confluyen para mostrar que De repente puede ser leída como una novela moderna en medio de un contexto donde predomina un tipo de novela criollista.

En esta investigación se lleva a cabo un análisis de la ambigüedad terminológica presente en la bibliografía cuando se hace referencia a la afirmación y a la respuesta afirmativa. A su vez, ofrecemos una propuesta terminológica para distinguir entre los distintos tipos de respuestas afirmativas que puede resultar muy productiva en el análisis del discurso interactivo y, específicamente, en el estudio de los marcadores discursivos. Así, defendemos la distinción entre los conceptos de aceptación, acuerdo, confirmación y respuesta afirmativa categórica, tomando como criterio el tipo de intervención iniciativa precedente. Para mostrar el rendimiento de esta propuesta, exponemos su aplicación a varios fragmentos de discurso interactivo real extraído del Corpus MEsA. Nuestro marco teórico-metodológico es la Lingüística de Pragmática, formulada por Fuentes Rodríguez (2017 [2000]).

Authors: Alvarado Camila , Nazar Rogelio
Published: July 2024

Los marcadores discursivos han sido objeto de estudio de numerosas investigaciones en las últimas décadas, y se ha profundizado en su definición y clasificación en el ámbito más general de las partículas, es decir, las partes invariables del discurso. En el presente artículo se describe una propuesta metodológica basada en un enfoque mixto (cuali-cuanti) para la detección automática de marcadores discursivos parentéticos a través de un corpus paralelo inglés-castellano. Proponemos un algoritmo que identifica indicios de una función de marcador discursivo de una unidad y, de ser el caso, su carácter polifuncional. Se presentan resultados de un estudio dirigido a la categoría específica de los conectores causal-consecutivos. El algoritmo en primer lugar determina la eventual condición de marcador discursivo de la unidad, luego señala si pertenece a la categoría específica de conectores causal-consecutivos y, finalmente, señala si hay indicios de polifuncionalidad.

Published: July 2024

ABSTRACT: Abiotic stresses, such as heat, drought and salinity, affect the development of wheat crop and hinder its expansion to the central region of Brazil. The identification of genotypes tolerant to these conditions is important for improving yield performance. The present research evaluated the impact of different abiotic stresses on germination and seedling development and selected wheat genotypes tolerant to these stresses, using multi-trait analysis. Heat, drought and salinity stresses were induced in seeds of 23 wheat genotypes. Seed germination, seedling length and dry mass were evaluated. An adaptability and stability model and a multi-trait selection index were applied to the data. Drought and salinity negatively affected the development of seedlings of the 23 evaluated genotypes. However, the VI 14055, ORS Madre Pérola and BRS 404 genotypes conferred the best adaptability and stability results and were selected by the MGIDI, which revealed that great performance can be achieved in regions with potential for abiotic stress, in the early stages of development.
Physical-chemical characterization, acceptance test, and free-choice profiling of gluten-free bread developed with Brazilian buckwheat starch and flour

Published: July 2024

ABSTRACT: Buckwheat is a pseudocereal with a high starch content and compounds of nutritional interest, making it suitable for use in gluten-free baking. A simplex-centroid design was employed to investigate the effects of the mixture components of buckwheat flour, buckwheat starch, and rice flour in nine different proportions. The minimum and maximum limits for the components were 10% and 30% for buckwheat flour, 20% and 40% for buckwheat starch, and 50% and 70% for rice flour, aiming to create diverse gluten-free breads for evaluation. The utilized flours underwent characterization, and their micro- and macronutrient amounts, along with their amino acid compositions, were determined. Specific volume analysis, water loss determination, texture assessment, and sensory evaluations were conducted on the breads. It was observed that the proportion of starch and buckwheat flour directly influenced the specific volume and water loss during product storage. Through sensory analysis, the formulation with the highest acceptance and purchase intention among tasters was identified. Free-choice profiling analysis established the sensory profiles of the developed gluten-free bread formulations. According to tasters, the formulations exhibited characteristics of whole meal bread, noticeable softness, and a homogeneous alveolar distribution. The gluten-free bread was well-received by 124 tasters, with a purchase intention rate of 93.55%.

Abstract We aimed to characterize the adult and regenerating tree components and their relationships with soil characteristics of a native vegetation remnant in Cuiabá, Mato Grosso, Brazil. The area of the fragment is stratified into “dry area” (lithic neosoil) and “damp area” (gleisoil). We conducted a forest inventory with a random distribution of 25 parcels. We analyzed the physical and chemical components of the soil. We evaluated the vegetation's horizontal structure, diversity, and sample sufficiency using the Bootstrap richness estimator. We classified the species according to dispersal syndrome and ecological group. Overall, we found 93 species in the adult layer and 70 species in the regenerating layer. The similarity dendrograms based on the two evaluated indices demonstrated the existence of the two initially stratified environments in both strata. The IndVal (%) indicated that the set of indicator species differed between the strata. Thereby, the fragment is in an intermediate stage of successional progression. PCA showed that plots in the wet area had higher pH values and Ca, Zn, and Fe levels, while plots in the dry area did not clearly distinguish, varying in terms of K, B, and organic matter content. In CCA, a set of species that occurred exclusively in the damp area showed a strong relationship with the analyzed variables. The area is a diverse ecosystem that efficiently provides ecosystem services to society and should be the subject of long-term conservation and research.
Checklist and geographic distribution of Myrtaceae species occurring in campinaranas of the Brazilian Amazon
Authors: NATIVIDADE Paulo Haniel Sousa da , BARBERENA Felipe Fajardo Villela Antolin , SILVA Rachel Macedo da
Published: July 2024

ABSTRACT White-sand vegetation (campinarana) is a type of vegetation restricted to oligotrophic and highly leached white sand soils in the Amazon phytogeographic domain that includes grassland to forest phytophysiognomies. Campinaranas cover about 5% of this phytogeographic domain and are impacted by various anthropic activities that put plant species, especially endemic ones, at risk. Myrtaceae has significant representativeness in oligotrophic edaphic environments, but floristic and taxonomic studies on the family in campinaranas are still few and geographically limited. We present a checklist of Myrtaceae species known from campinaranas of the Brazilian Amazon based on the survey of herbarium specimens and literature data in order to assess the level of endemism of these species for this vegetation type. We compiled occurrence records of 72 species and six genera. Myrcia and Eugenia were the genera with the highest number of species. Overall, 38 species (53%) occurred only in the Amazon and two were endemic to campinaranas (Eugenia campina and Myrcia psammophila). Four species are new records for the Brazilian Amazon: Blepharocalyx salicifolius, Eugenia hatschbachii, Myrcia anceps and Myrcia racemosa. The specific richness of Myrtaceae in Brazilian campinaranas is likely to be underestimated since extensive areas, especially those farther from the riverbanks, in the states of Amazonas and Roraima, have not yet been intensively surveyed.

Published: July 2024

ABSTRACT Objective: To analyze the association between patient safety culture and professional quality of life in nursing professionals. Method: Correlational study carried out in a hospital in Salvador, Bahia, Brazil, with 180 participants. The data were collected through the Hospital Survey on Patient Safety Culture and Professional Quality of Life Scale and analyzed with correlation tests. Results: The use of the Quality of Professional Life model, which encompasses Compassion Satisfaction, Burnout and Traumatic Stress, showed that a better assessment of the safety culture was negatively associated with Burnout. Regarding the dimensions of culture, better evaluations of the general perception of safety, teamwork and staffing were negatively associated with Burnout and Traumatic Stress. Higher Burnout was negatively associated with better handoffs and greater Traumatic Stress was positively associated with error communication. Conclusion: Higher levels of Burnout were associated with worse perception of safety culture and worse teamwork evaluations; staffing and general perception of safety were associated to a higher level of Burnout and Traumatic Stress, which emphasizes the importance of investment in these areas.

ABSTRACT Objective: To identify health promotion strategies used by managers in primary health care. Method: Qualitative research, of a participant action nature, which adopted the Culture Circle proposed by Paulo Freire as its methodological reference. Eleven primary health care managers from a medium-sized municipality in southern Brazil took part. Results: Nine generative themes emerged, categorized into four themes that highlight the interconnection between health promotion, social determinants and primary health care. These themes highlight preventive approaches, healthy habits and underline the need for a multidisciplinary approach to health care, recognizing the complexity of the dimensions involved, the influence of social determinants, environmental and health issues. These aspects call for intersectoral policies and actions, demonstrating the viability of health promotion in line with the principles of the Unified Health System. Final considerations: The autonomy of professionals working in primary health care services is highlighted, especially that of nurses, who play a central role in connecting and organizing health promotion actions.

Automated journalism in news about traffic accidents: emergency services information dump
Authors: Julián Francisco Javier Olivar de
Published: July 2024

Abstract In this work, the process of producing news about events in the Spanish digital press has been studied. A content analysis was carried out on news related to the main external causes of mortality (traffic accidents, accidental falls, drowning and suicides) published in the six main Spanish digital media ( elpais.com , elmundo.es , abc.es , lavanguardia.com , elconfidencial.com and 20minutos.es ) during the period 2010-2020. The selected news items ( \begin{equation}n=5,727\end{equation} n = 5 , 727 ) were obtained through the digital newspaper library Mynewsonline . A qualitative study has also been carried out (in-depth interviews with professionals and a focus group). The results show a high number of news items published on traffic compared to other external causes of death with higher mortality. It is also appreciated that the media automatically transfer the information they receive from the emergency services. It has even been detected that most of the news events coded in this study are exact copies that are published on the same day in different media (headlines and the body of the news).
Effect of fertilizers and planting methods on safflower fatty acid profile1
Authors: Sabaghnia Naser , Janmohammadi Mohsen
Published: July 2024

ABSTRACT Soils in semi-dry areas lack sufficient nutrients for crops, so their yield depends on fertilizers and planting methods. This study aimed to investigate how the fatty acids in safflower oil change with the use of fertilizers and planting methods. Five fertilizers [F1: control; F2: 10 t ha-1 of farmyard manure; F3: 20 t ha-1 of farmyard manure; F4: NPK (130:60:45 kg ha-1); F5: nano-Fe and nano-Zn] and four planting patterns (P1: 40-cm furrow planting; P2: 60-cm furrow planting; P3: 40-cm ridge planting; P4: 60-cm ridge planting) were tested. A biplot analysis explained 73 % of the variability, with the first and second principal components accounting for 54 and 19 %, respectively. The polygon-view was divided into five sections, with F3-P4 being the best for oil and protein contents, stearic (18:0), oleic (18:1), linoleic (18:2), linolenic (18:3) and lauric (12:0) acids, and iodine value. The vector-view showed a positive association among iodine value, oil content and linoleic, oleic, linolenic, stearic and lauric acids, as well as between myristic acid (14:0) and protein content, and between saponification and peroxide values. The best treatments were F4-P4, F4-P3 and F5-P4. Therefore, using NPK chemical fertilizer or nano-Fe and nano-Zn, combined with planting on a ridge with a 40 or 60-cm interrow distance, can be beneficial for producing high-quality safflower oil.

ABSTRACT Introduction: Extraction vs. non-extraction is a crucial decision in orthodontic therapy. Objective: The aim of the present study was to investigate the changes in the dental arch width and buccal corridor after orthodontic treatment using extraction and non-extraction therapy with Damon self-ligating system. Material and Methods: This retrospective study consisted of 35 patients (20 female and 15 male patients with median age of 12.5 years), treated by extracting 4 or 2 premolars, and 37 patients (16 female and 21 male patients with the median age of 12.8 years), treated without premolar extraction. Both groups were treated with Damon self-ligating system. Plaster models before (T0) and after (T1) treatment were measured, and the arch width values were determined at the level of the first molars, second premolars, canines and palatal rugae. Buccal corridor width was measured using the extraoral images at T0 and T1. Paired t-test was used for the analysis of the normally distributed data, and Wilcoxon Mann-Whitney U test was used for the data with non-normal distribution. Values of p<0.05 were set as statistically significant. Results: The upper intercanine width increased significantly in both groups (p<0.01). In the non-extraction group, the arch width increased significantly in the maxillary second premolar and first molar region (p<0.01) as well as in the region of the canines (p=0.04), second premolars (p=0.01) and first molars (p<0.01) of the mandible. The buccal corridor decreased significantly in the non-extraction group (p<0.01). Conclusion: Premolar extraction in combination with Damon self-ligating system did not lead to reduction of the dental arch width in the maxilla, nor did it increase the size of the buccal corridors.

Published: July 2024

ABSTRACT The utilization of organic fertilizer for a short cycle crop may allow planting, in sequence, another short cycle crop, without the need for new fertilizers, reducing the costs of a new fertilization. The objective of this study was to evaluate the residual effect of fertilization applied to broccoli with phosphorus sources in the presence and absence of organic compost, on beet and chicory production in subsequent cultivation. In broccoli cultivation, four sources of phosphorus (thermophosphate, natural phosphate, natural reactive phosphate, and triple superphosphate) (600 kg/ha of P2O5) were evaluated in the presence and absence of organic compost (Visafértil®, 55 t/ha) before planting. After the removal of the cultural remains of broccoli, beet and chicory, seedlings were transplanted in the same plots of the first crop treatments. For each species eight treatments were evaluated, in a 4 x 2 factorial scheme. The first factor were the four sources of phosphorus and the second one was the application or not of organic compost before broccoli (hybrid BRO 68) planting. Treatments with organic compost showed greater production of beet and chicory, compared to the absence of compost. Fertilization with organic compost associated to the phosphorus sources provides necessary residual effect to beet and chicory production. The best P source for beet was triple superphosphate, and for chicory, in the absence of organic compost, triple superphosphate was the best source. In the presence of organic compost, the best sources were triple superphosphate and natural phosphate.

Authors: Ihalainen Hannes , Berg Jeremias , Järvisalo Matti
Published: July 2024

Maximum satisfiability (MaxSAT), employing propositional logic as the declarative language of choice, has turned into a viable approach to solving NP-hard optimization problems arising from artificial intelligence and other real-world settings. A key contributing factor to the success of MaxSAT is the rise of increasingly effective exact solvers that are based on iterative calls to a Boolean satisfiability (SAT) solver. The three types of SAT-based MaxSAT solving approaches, each with its distinguishing features, implemented in current state-of-the-art MaxSAT solvers are the core-guided, the implicit hitting set (IHS), and the objective-bounding approaches. The objective-bounding approach is based on directly searching over the objective function range by iteratively querying a SAT solver if the MaxSAT instance at hand has a solution under different bounds on the objective. In contrast, both core-guided and IHS are so-called unsatisfiability-based approaches that employ a SAT solver as an unsatisfiable core extractor to determine sources of inconsistencies, but critically differ in how the found unsatisfiable cores are made use of towards finding a provably optimal solution. Furthermore, a variety of different algorithmic variants of the core-guided approach in particular have been proposed and implemented in solvers. It is well-acknowledged that each of the three approaches has its advantages and disadvantages, which is also witnessed by instance and problem-domain specific runtime performance differences (and at times similarities) of MaxSAT solvers implementing variants of the approaches. However, the questions of to what extent the approaches are fundamentally different and how the benefits of the individual methods could be combined in a single algorithmic approach are currently not fully understood. In this work, we approach these questions by developing UniMaxSAT, a general unifying algorithmic framework. Based on the recent notion of abstract cores, UniMaxSAT captures in general core-guided, IHS and objective-bounding computations. The framework offers a unified way of establishing quite generally the correctness of the current approaches. We illustrate this by formally showing that UniMaxSAT can simulate the computations of various algorithmic instantiations of the three types of MaxSAT solving approaches. Furthermore, UniMaxSAT can be instantiated in novel ways giving rise to new algorithmic variants of the approaches. We illustrate this aspect by developing a prototype implementation of an algorithmic variant for MaxSAT based on the framework.

Background: The therapeutic use of gingival mesenchymal stem cells (GMSCs) as autologous cells may pose the challenge of alterations inflicted by the hyperglycemic environment. Objective: This study aims to assess the effects of hyperglycemia on the characteristics of GMSCs in diabetics. Materials and Methods: 10 patients who consented and fulfilled the criteria for inclusion and exclusion were recruited and categorized as test (HbA1c > 6.5) and control (HbA1c < 6.0). Gingival explants were obtained from gingival collar of teeth, washed, digested and cultured. The cells were subjected to microscopic observation to assess phenotype characteristics, and flow cytometry and qRT-PCR to assess differentiation potential. Stem cell markers CD90, CD73, CD105, CD34, CD45, HLA DR & HLA ABC, osteogenic differentiation markers RUNX2 & OCN, adipogenic differentiation markers PPARG2 & FABP4 and chondrogenic differentiation markers SOX9 & AGCN were evaluated. Results: Microscopic appearance of spindle shaped cells was found to be comparable in both groups. Flow cytometry results demonstrated comparable expressions with both groups, samples being positive for CD90, CD73, CD105, HLA ABC and negative for CD34, CD45 & HLA DR. There were variations in the expression of markers when assessed for differentiation potentials. Conclusions: The hyperglycemic environment did not manifest any changes in the phenotypic characteristics of GMSCs among diabetics. However, the expression of certain differentiation markers was significantly altered in the diabetic test population included. Further research is being conducted to understand the GMSCs in a hyperglycemic environment with an aim to develop strategies to optimize its clinical implications.

Introduction: Periodontal inflammation causes dysbiosis and change in the microbiota. Nonsurgical periodontal therapy (NSPT) helps in removal of plaque and restoring periodontal health. Various adjunctive therapy like use of mouthwash helps in maintenance of periodontal health and reducing inflammatory load. Materials and Methods: A total of 108 subjects diagnosed with type 2 diabetes mellitus and periodontitis were divided into three groups: Group 1 received NSPT and rinsing with 0.2% chlorhexidine mouthwash for 3 months, Group 2 received NSPT and rinsing with 1.5% hydrogen peroxide mouthwash for 3 months, Group 3- received NSPT only (control group). The clinical parameters measured included Plaque Index (PI), Gingival Index (GI), Bleeding on probing (BOP) and probing (PD) at baseline, 1, 2, 3 months follow up. Salivary interleukin 1βlevels were measured at baseline and 3 months interval. Results: Group 1, 2 and 3 showed significant reduction in PI, GI, BOP and PD at 1 and 3 months follow up (p<0.05). However, Intergroup comparison of clinical parameters showed significant reduction in group 1 and 2 when compared with group 3 (p<0.05). Salivary interleukin 1-β levels showed significant reduction from baseline to 3 months in all the three groups and intergroup comparison didn’t show any significant changes, (p>0.05). Conclusions: Hydrogen peroxide mouthwash as an adjunct to NSPT can be considered as a safe and effective measure to reduce periodontal inflammation in type 2 diabetes mellitus patients with chronic periodontitis.

Introduction: Literature shows that individuals with disabilities, including hearing impairment, often suffer from untreated dental caries, poor oral hygiene, and compromised periodontal health, leading to adverse effects on oral health. Objetive: This study aims to analyze current evidence concerning dental care strategies for controlling, managing, and preventing biofilm accumulation in patients with hearing impairment. Materials and Methods: A systematic search was conducted in the databases Scopus, Web of Science, SciELO and PubMed between April and May 2022 to identify articles establishing a relationship between periodontal disease and hearing disability. Full-text articles published in English or Spanish between 2012 and 2022 were included. Results: Seventeen articles met the inclusion criteria and were analyzed. These included cross-sectional studies, cohort studies, clinical trials, case reports, and case-control studies. Most studies reported fair to poor oral health status among individuals. Nine different interventions or management approaches for treating periodontal disease in patients with hearing impairment were identified. Conclusions: The current global evidence on the association between periodontal disease and hearing impairment is very limited. Dentists may need to employ various strategies to address communication barriers, as outlined in this study.

A morphological study on the question of the hybrid origin of Astrophytum coahuilense (Cactaceae)
Authors: Montanucci Richard R.
Published: July 2024

Two alternative hypotheses may explain the origin of Astrophytum coahuilense. One hypothesis is that A. coahuilense is an ancient diploid hybrid derived from interbreeding between A. capricorne and A. myriostigma. An alternative is that A. coahuilense arose via allopatric speciation and its similarity to A. myriostigma in vegetative characters is due to convergent evolution. The two hypotheses are tested, applying univariate analysis and Non-metric Multidimensional Scaling analysis to morphological datasets. Univariate analysis, which is based on 13 vegetative and 10 reproductive characters, shows that the morphology of A. coahuilense is complex, consisting of a combination of vegetative and reproductive characters shared with both A. capricorne and A. myriostigma as well as several intermediate traits. Furthermore, the morphology of A. coahuilense lacks unique, fixed characteristics. Non-metric Multidimensional Scaling analysis of 15 characters (three vegetative and 12 reproductive traits) produced a two-dimensional scatterplot in which the cluster representing A. coahuilense occupies a position intermediate between the clusters of the two parental species along Dimension 1. Thus, both analyses support the hypothesis that Astrophytum coahuilense originated through hybridization between A. capricorne and A. myriostigma. Biological and ecological factors that may have facilitated homoploid hybrid speciation are discussed.
