Purpose
Serum cortisol and inflammatory markers may play a role in depression and anxiety, but little is known about whether various features of serum cortisol and inflammatory markers have different associations with depression and anxiety. This study examines the associations of serum cortisol and inflammatory marker features with depression and anxiety in young women with gynecologic cancer.
Methods
Sixty-four young women with gynecologic cancer, aged 15–39 years, were recruited in a tertiary general hospital in China from May to December 2021. The Hospital Anxiety and Depression Scale was used to evaluate depression and anxiety. Blood samples were taken at 8am, 4pm and 10pm on the same day to examine the various features (average, variability and diurnal patterns) of serum cortisol and inflammatory markers, namely C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α).
Results
Young women with gynecologic cancer who reported depression/anxiety had significantly higher average levels of serum cortisol, IL-6 and TNF-α than those who did not. The dysregulations in the diurnal patterns of serum cortisol and IL-6 were associated with depression and anxiety. Serum cortisol levels were significantly higher in the depression/anxiety group at 10pm. Depression and anxiety were associated with elevated levels of IL-6 and TNF-α at each time point.
Conclusion
This study revealed various associations of serum cortisol and inflammatory marker features with depression and anxiety in young women with gynecologic cancer. Further research is needed to understand the role of serum cortisol and inflammatory marker features in the progression of depression and anxiety.

Conservation interventions have wide-ranging social impacts - both positive and negative. Yet a limited understanding of how conservation initiatives affect people’s livelihoods often hinders our ability to learn from past efforts and design more effective and equitable conservation measures. This is particularly needed when there is a high degree of overlap between critical habitats and human activities or a high cultural and economic demand for products derived from the conservation target. Here, we explore the social impacts of sea turtle conservation initiatives implemented on São Tomé Island (Gulf of Guinea) as a case study and consider how these might enhance or hinder future efforts. Semi-structured interviews were conducted with key actors involved in the sea turtle trade in December 2014-February 2015 (prior to the implementation of key initiatives) and February-April 2022. Our findings suggest a clear reduction in the scale of the sea turtle trade and the number of main actors involved. However, most of the interviewees previously involved in the trade had experienced economic displacement and several associated social impacts, such as the reduced ability to support family and friends and food insecurity, due to trade restrictions. Financial capital was the main barrierto transitioning to alternative livelihoods, followed by the lack of skills and peer pressure. Finally, this study highlights the importance of considering human dimensions during the planning and implementation phase of conservation actions and the need for more investment focused on the well-being of communities to ensure the long-term survival of endangered species.

Authors: Leta Temesgen Desta , Chen Jingbing , Achab Abdelfattah El
Published: June 2023

A diverse range of traveling wave structures of fractional complex Ginzburg-Landau equation with Kerr law and power-law nonlinearity are obtained by using the bifurcation method. The existence of wave solutions is guaranteed by reporting constraint conditions and with the help of traveling wave transformation the governing model is converted into the planar dynamical system. Every bounded phase orbits are plotted for pertinent parameters. We also extract the nonlinear periodic solutions of the considered problem and outcomes are presented graphically with the help of contemporary software that allows computation of equations within the symbolic format. Furthermore, the quasiperiodic and chaotic behavior and sensitivity of the model is analyzed for different values of parameters after deploying an external periodic force and on some initial value.

Authors: Bo Kaida , Liu Xin , Ou Jianliang , Zhang Yuanyi , Wang Xu , Yang Shuo , Zhang Wei , Zhang Lelei , Chang Jun
Published: June 2023

Background: To determine whether novel meniscus parameters are predictive of incident radiographic knee osteoarthritis (ROA) over four years in the Osteoarthritis Initiative (OAI) study.
Methods: Participants were extracted from the Osteoarthritis Initiative (OAI) study. 178 knees (from 176 patients ) with incident ROA (Kellgren Lawrence Grade (KLG) 0 or 1 at baseline (BL), developing KLG 2 or greater by year 4) were matched one-to-one by gender, age and radiographic status with 178 control knees (from 178 patients) not developing incident ROA. Novel meniscal parameters were measured on coronal T2-weighted turbo spin echo (TSE) MRI. Conditional logistic regression analyses were used to assess the risk of incident ROAassociated with novel meniscus parameters after adjustment for covariates. Sensitivity analysis was performed for P0 (time to visit when ROA was found on the radiographs) , P1 (1 year prior to P0) and baseline (enrollment period) ROA incidence.
Results: Intra-class and inter-class reliabilities of measurement of novel parameters were excellent (≥0.89). Baseline meniscus measurement parameters included the mean of MLD [mean(MLD)], the mean of RMLD [mean(RMLD)] and the mean of TPW[Mean(TPW)]. Baseline Mean(MLD) and Mean(RMLD) [Mean(MLD), Mean(RMLD)] [Adjusted OR, 95%CI: 1.11(1.07 to 1.16) and 1.13(1.09 to 1.17), respectively] were associated with incident ROA during 4 years, but mean value of tibial plateau width [Mean(TPW)] [Adjusted OR, 95%CI: 0.98(0.94 to 1.02)] was not associated with incident ROA during 4 years. At baseline, Mean (MLD) and Mean (RMLD) were significantly different between case and control groups. While P1 and P0 [Mean(TPW)] were not associated with incident ROA risk, other measures of P1 and P0 were significantly positivelyassociated with incident ROA risk.
Conclusions: The novel method of measuring meniscus novel parameters on MRI is reproducible. Compared with the control group, Mean(MLD) and Mean(RMLD) at baseline, P1 and P0 periods are higher in the case group than in the control group and the measurement differed significantly among the groups. These novel meniscus parameters alterations could be an important imaging biomarker to predict the occurrence of ROA.
Regionally adjusted stochastic earthquake ground motion models, associated variabilities and epistemic uncertainties
Authors: SUNNY JALEENA , de Angelis Marco , Edwards Benjamin
Published: June 2023

An optimization-based calibration technique, using the area metric, is applied to determine the input parameters of a stochastic earthquake-waveform simulation method. The calibration algorithm updates a model prior, specifically an estimate of a region’s seismological (source, path and site) parameters, typically developed using waveform data, or existing models, from a wide range of sources. In the absence of calibration, this can result in overestimates of a target region’s ground-motion variability, and in some cases, introduce biases. The proposed method simultaneously attains optimum estimates of the median, range and distribution (uncertainty) of these seismological parameters, and resultant ground motions, for a specific target region, through calibration of physically-constrained parametric models to local ground motion data. We apply the method to Italy, a region of moderate seismicity, using response spectra recorded in the European Strong Motion (ESM) dataset. As a prior, we utilise independent seismological models developed using strong-motion data across a wider European context. The calibration obtains values of each seismological parameter considered (such as, but not limited to, quality factor, geometrical spreading and stress drop), to develop suits of optimal parameters for locally adjusted stochastic ground motion simulation. We consider both the epistemic and aleatory variability associated with the calibration process. We were able to reduce the area metric (misfit) value by up to 88% for the simulations using updated parameters, compared to the initial prior. This framework for the calibration and updating of seismological models can help achieve robust and transparent regionally adjusted estimates of ground motion, and to consider epistemic uncertainty through correlated parameters.

Authors: Shah Amika , Shahil Anam , Nolan Robert P , Strudwick Gillian , Sockalingam Sanjeev , Seto Emily
Published: June 2023

Background
Mental health conditions are common among people living with complex chronic conditions (PLWCCC), yet recognition and treatment are low in medical settings.
Methods
To design appropriate mental health services for this population, a qualitative study was conducted to identify the factors affecting access to mental health care for PLWCCC. The study involved 13 PLWCCC enrolled in a heart failure management program, as well as 9 clinicians and researchers with expertise in mental health care and/or complex chronic conditions, recruited from a large academic hospital in Ontario, Canada between March 2021 and March 2022. Data collected from one-on-one semi-structured phone interviews were analyzed using inductive reflexive thematic analysis, and the resultant themes were mapped to the domains of Levesque’s patient-centred access to care framework.
Results
A total of 14 themes were identified, revealing barriers to mental health care at the system and patient levels. System-level barriers included health care system and service approachability (difficulties detecting mental health concerns; unpreparedness for referral conversations), availability and accommodation (available mental health services were limited; services were poorly timed; pathways to care were inconsistent), and affordability (limited human resources; lack of options for choice or finding fit; insufficiency of generic mental health services). Patient-level barriers included limitations in the ability to perceive mental health needs (low mental health literacy; denial, stoicism, and self-reliant coping methods), as well as seek (stigma), reach (inconvenience of in-person delivery), and pay (lack of full insurance coverage and high cost of psychological services) for mental health care hindered access.
Conclusion
Given the multi-level factors identified that hinder access to mental health care services for this population, service pathways should seek to enhance the approachability, availability, and appropriateness of mental health services and promote the ability of PLWCCC to perceive their mental health needs.

Introduction: The MCQ is one of the objective assessment methods. It is proper to evaluate the cognitive domain of learners with high objectivity. However, there are no definite criteria for determining the appropriate exam time. The ability to comprehend the meaning of a text, when reading, cannot be directly applied to reading for decision-making or answering questions. The authors were interested in exploring the aspects of the medical students’ perspective about the factors affecting their discission on MCQs answering. Materials and Methods The study was conducted at the Institute of Medicine, Suranaree University of Technology, Thailand. The authors utilized a mixed method that consisted of a quantitative approach and a sequential, explanatory approach. Survey research was used as the part quantitative technique meanwhile the semi-structured interview was used in qualitative data analysis for collecting the data. Results The questionnaire was done online by the participants from second to fifth-year medical students. It was found that there were 298 respondents. The qualitative analysis indicated that there were five domains, including the total word count of tests, non-native English examiners, test difficulty, images in tests, and atmosphere of the examination affecting the testing time. Conclusion This report indicated that the data acquired from comprehensive reading examination should be distinguished from decisive reading examination. Apart from the length of text, the question taxonomy such as recall or application as well as questions with given images and tables should be considered as factors determining time allocation of a MCQ examination.

Authors: Wang Lei , Zhang Jianwei , Gu Song , Yu Jing , Yang Wenbing
Published: June 2023

Human action recognition exhibits limited accuracy in video surveillance due to the 2D information captured with the monocular cameras. To address the problem, a monocular depth estimation (SARDE)-based human skeleton action recognition method is proposed in this study. The proposed method comprises two tasks, i.e., human skeleton action recognition and monocular depth estimation, with the aim of transforming 2D human action into 3D. The two tasks are integrated with multi-task manner in an end-to-end training to fully utilize the correlation between action 1 recognition and depth estimation by sharing learning data to learn the depth features of the human skeleton joints more effectively for human action recognition. In this study, the graph-structured depth estimations methods with inception blocks and skip connections are investigated. The experimental results verify the effectiveness and superiority of the proposed model in skeleton action recognition, the model reaches state-of-the-art on the datasets.

Authors: Jauhari Muhammad Fauzan , Parenrengi Muhammad Arifin , Suryaningtyas Wihasto
Published: June 2023

Introduction
Spinal cavernomas (SC) are uncommon lesions with an overall incidence rate of 0.04–0.05% in the population. This vascular pathology accounts for 3–5% of all CNS lesions and accounts for approximately 15% of all spinal vascular malformations. SC is diagnosed based on the presence of neurological deficits and complaints from the patient. Clinical presentation depends on location. Early intervention could yield a better outcome.
Case Report
A female, 15 years old, came with complaints of pain in the back of the neck for 4 months before admission, the patient also felt weakness in the right limb for 2 months before admission. Patient wuth Brown Sequard syndrome involving the C1-C2 level, with a right hemiparesis and bowel and bladder incontinence. The patient had surgery because she was symptomatic.
Discussion
There are few indications for surgery in SC, but in general, surgery can be considered in patients with symptomatic lesion. One of the most commonly approaches is unilateral laminectomy, and this approach yields better outcomes when compared to laminoplasty or total laminectomy.
Conclusion
In our case, a 15-year-old female with an intramedullary mass in the cervical with clinical symptoms resembling Brown Sequard syndrome.The surgical results of treating this lesion were positive. This report highlights not only a unique case, but also the fact that in patients with progressive neurological decline, surgical intervention for spinal cavernomas can be performed safely and offers decompression, diagnosis, and prevention against further hemorrhage.
Externalization of an infected Vagus Nerve Stimulator generator without a break in anti- seizure therapy: A technical note
Authors: Karakas Cemal , Raichur Prachi , Mutchnick Ian
Published: June 2023

Vagus Nerve Stimulation (VNS) is a widely used treatment for drug-resistant epilepsy. An infection of the VNS generator pocket occurs in 3–8% of cases. Current standard of care requires the removal of the device, antibiotic therapy and then replacement of the device. The consequential break in VNS therapy leaves patients highly susceptible to seizures. Here, we report novel management of an infected VNS generator with externalization and short interval replacement of the entire system without any break in anti-seizure therapy. The patient is now seven months post-operative and without any evidence of infection.

Published: June 2023

As a new type of photocatalyst, molecular sieve photocatalysts have shown great promise in the degradation of organic matter in water bodies. In this paper, a new type of molecular sieve photocatalyst was successfully prepared by introducing Bi and La elements into the hydrothermal synthesis of SAPO-34 molecular sieve for the purpose of regulating the molecular sieve backbone. The introduction of active metals into the skeleton of molecular sieve can enrich the L acid sites on its surface, and at the same time, the introduction of active metals can accelerate the transfer rate of photogenerated carriers, which can also suppress the compounding rate of electron holes. It showed excellent performance in the photocatalytic degradation of formaldehyde, and the degradation rate constant k could reach 0.3222 min− 1 within 6 h. This study provides a new method for the preparation of molecular sieve photocatalysts and a new idea for the construction of bifunctional photocatalysts.
From the substance of electron to accurate dispersion formula
Authors: Tian Yunchuan
Published: June 2023

To investigate the distribution of electromagnetic potential, we conducted an experiment to measure the effect of the substance of an electron on the speed of light near a solid surface. Our findings show that the speed of light decreased as the distance to the solid surface decreased. To visually demonstrate these phenomena, we captured scientific images that, for the first time, depict the distribution of light speed between a single slit and the associated distribution of the substance of the electron behind it. Moreover, we developed a precise electron substance dispersion formula, which takes into account the motion of the substance along with the electron, allowing us to predict the refractive index with a level of accuracy that has not been previously achieved.

Published: June 2023

Proposed article deliver an integrative operational matrix scheme for solving integro differential equations (IDEs) that are predicated on modified Lucas wavelets (MLWs). In this scheme, we first create the MLWs integral operational matrix and then use the MLWs approximation scheme for transforming the integro differential equation (IDE) into well-famous algebraic equations system. Finally, we address some examples to show the impact and accuracy of the suggested scheme and the results are contrasted with current techniques or schemes, which illustrates that the suggested scheme is offers improved results with high effectiveness. Consequently, in the future, the modified Lucas wavelets-based scheme may be applied to solve other functional differential equations.

Published: June 2023

The clinical spectrum of Cerebral palsy (CP) can differ in various places depending upon the knowledge of the people and resources for prevention, diagnosis and management. Although studied extensively in high-resource countries, adequate data related to CP from resource-constraint settings are lacking.

The aim: The present study is a descriptive study done on clinical profiles, aetiology, and comorbidities.

Materials and methods: Present study is a hospital-based descriptive study of 80 children with Cerebral Palsy from January 2020 to June 2021 (18 months) admitted to Niloufer Hospital for Child Health, cases chosen as per inclusion criteria guided by "The Definition and classification of cerebral palsy, April 2006 International consensus". Clinical history and clinical examination and necessary investigations using a systematically designed proforma

Results: The most common types were spastic type (78.9 %) and hypotonic type (12.5 %). Spastic quadriparesis (55 %) was the most common among subtypes. Males were more affected than females, with more rural than urban distribution. 48.8 % belonged to the lower middle and 37.5 % to the upper lower class of socio-economic status. Consanguinity was observed in 33 %, and 3 % had a similar family history. A high incidence (65 %) was seen in firstborn children. Term gestation was commonest at 87 % and prematurity at 13 %. 91.3 % of the cases were institutional deliveries. For causes of cerebral palsy, 45 % required resuscitation at birth, 2.5 % had neonatal sepsis, 1.25 % had a cerebral malformation, 7.5 % had an intracranial bleed, 7.5 % had post-meaning encephalitic sequelae, 1.3 % had TORCH infection. Comorbidities Like mental retardation were seen in 90 %, seizure disorder in 87.5 %, visual problems in 24.8 %, hearing problems in 13.75 %, 56.25 % of cases were malnourished.

Conclusions: Comorbidities are significantly observed in cases of cerebral palsy. Appropriate screening and management of comorbidities, especially vision, hearing, speech, seizures, and nutrition, improve the overall prognosis in cases of Cerebral palsy.

The schooling experience of Black girls in private schools is complex and nuanced. To explain this unique experience, a composite narrative was written by the first researcher based on the lived experiences of 12 Black female graduates of private schools. The composite narrative design entailed conducting semi-structured interviews. The criterion-based sample gathered using the snowball method included 12 participants who identified as Black female graduates of prekindergarten through grade 12 education (P-12) private schools in the United States. The literature suggests that Black female students need specific support in the school community, a critically conscious school culture, a strong school–home connection, a diverse faculty, and a culturally responsive curriculum that reinforces their identity to ensure a positive learning experience. Through exploration of the racialized schooling experience Black female students have in the classroom, the first author identified what racial cognitive dissonance, resilience, and resistance look like in these students. In consideration of participants’ academic experiences, the researcher explored what role a sense of belonging, support systems, and institutional connections had in their schooling experience. Private schools can use these findings as guidance not only to recruit students, but also to determine what they need to do to retain students and ensure their alumni return as future parents or donors. Finally, private schools that work to create a critically conscious school culture can craft positive learning experiences that produce confident students who feel seen in their school community.

Published: June 2023

Research exploring the experiences of Black women attending predominantly White institutions in the U.S. is emerging. However, scholarship centering Black women’s experiences within Ivy League institutions remains elusive. This study explores the experiences of six Black women Ivy League collegians and their perceptions about how race, gender, and ethnicity shaped their sense of identity and campus interactions while attending an Ivy League institution. Using Black Feminist Thought as the theoretical framework, findings illustrate salient stressors and challenges while navigating interactions with peers, professors, and other university personnel. This study’s findings broaden our understanding of Black women college student experiences within Ivy League institutions and informs institutions of higher education on strategies to best support them.
Strong Hilbert space fragmentation via emergent quantum drums in two dimensions
Authors: Chattopadhyay Anwesha , Mukherjee Bhaskar , Sengupta Krishnendu , Sen Arnab
Published: June 2023

We introduce a disorder-free model of S=1/2S=1/2 spins on the square lattice in a constrained Hilbert space where two up-spins are not allowed simultaneously on any two neighboring sites of the lattice. The interactions are given by ring-exchange terms on elementary plaquettes that conserve both the total magnetization as well as dipole moment. We show that this model provides a tractable example of strong Hilbert space fragmentation in two dimensions with typical initial states evading thermalization with respect to the full Hilbert space. Given any product state, the system can be decomposed into disjoint spatial regions made of edge and/or vertex sharing plaquettes that we dub as "quantum drums". These quantum drums come in many shapes and sizes and specifying the plaquettes that belong to a drum fixes its spectrum. The spectra of some small drums is calculated analytically. We study two bigger quasi-one-dimensional drums numerically, dubbed "wire" and a "junction of two wires" respectively. We find that these possess a chaotic spectrum but also support distinct families of quantum many-body scars that cause periodic revivals from different initial states. The wire is shown to be equivalent to the one-dimensional PXP chain with open boundaries, a paradigmatic model for quantum many-body scarring; while the junction of two wires represents a distinct constrained model.

Published: June 2023

Waveguide QED with cold atoms provides a potent platform for the study of non-equilibrium, many-body, and open-system quantum dynamics. Even with weak coupling and strong photon loss, the collective enhancement of light-atom interactions leads to strong correlations of photons arising in transmission, as shown in recent experiments. Here we apply an improved mean-field theory based on higher-order cumulant expansions to describe the experimentally relevant, but theoretically elusive, regime of weak coupling and strong driving of large ensembles. We determine the transmitted power, squeezing spectra and the degree of second-order coherence, and systematically check the convergence of the results by comparing expansions that truncate cumulants of few-particle correlations at increasing order. This reveals the important role of many-body and long-range correlations between atoms in steady state. Our approach allows to quantify the trade-off between anti-bunching and output power in previously inaccessible parameter regimes. Calculated squeezing spectra show good agreement with measured data, as we present here.

Los términos multidisciplina, interdisciplina y transdisciplina son más usados que definidos, lo que genera que sean términos confusos; por lo que requieren ser clarificados. Realizamos un análisis morfológico-semántico para delimitar el significado de los términos estudiados con el apoyo de definiciones de diccionarios en cuatro idiomas. Se apela al significado histórico y filosófico del concepto disciplina y a diversas conceptualizaciones institucionales y académicas de los términos estudiados que se derivan de disciplina. La descripción de prefijos multi-, inter- y trans- y del sufijo -dad, junto con el análisis histórico y filosófico del término disciplina permiten llegar a diferentes tipologías de los conceptos multi, inter y transdisciplina y dar cuenta de su historicidad.
Representaciones sociales de la discapacidad en estudiantes de nivel medio superior
Authors: Pérez Castro Judith , Piña Osorio Juan Manuel
Published: June 2023

En este artículo se analizan las representaciones sociales sobre las personas con discapacidad en una muestra de estudiantes del nivel medio superior, de dos entidades del país: Oaxaca y el Estado de México. El método utilizado fue de tipo asociativo, para lo cual se diseñó un instrumento en donde se les pedía a los participantes escribir tres palabras relacionadas con «persona con discapacidad» y después que argumentaran brevemente el porqué de cada una. El análisis de la información se basó en la técnica de las redes semánticas naturales. Los resultados dieron lugar a una red integrada por 107 definidoras, con peso semántico de 587. Con base en esta diversidad de términos, se identificaron cuatro tipos de representaciones: Social, Médico-rehabilitadora, Trágico-asistencialista y Optimista. Las dos primeras registraron los pesos semánticos más altos, 223 y 184 respectivamente; las dos últimas obtuvieron puntajes de 103 y 73 cada una. Estos hallazgos, aunque parecieran ser contradictorios, nos muestran que las representaciones sociales no son entidades monolíticas, al contrario, en ellas se conjugan el saber científico y el sentido común; tampoco son exclusivas de un grupo determinado, sino que son producto de la información que se difunde a través de los diferentes agentes socializantes.

Solid-state fermented apple pomace (AP-SSF) enriched with non-nitrogen protein has been studied as an alternative ingredient for feeding dairy cattle. The present study aimed to evaluate the effect of the inclusion of AP-SSF in the feeding of dairy cows in early lactation on the yield and quality of milk, microbial contamination, and ruminal fermentation parameters, as well as the concentration of ammonia and the number of protozoa. Twenty Holstein cows were used, 20 of 660 kg on average, with 2-4 lactations and an average of 89 days in milk. Two groups were formed with ten cows each, randomly distributed to form a 2 x 2 Latin square with standard periods. Experiment diets were formulated with traditional ingredients, and one of them was added AP-SSF. Rations were gradually incorporated, giving ten days for adaptation and another 20 days for sampling. In lactose and production variables, no difference was statistically significant (P> 0.05) in milk fat and protein differences (P < 0.05) in the first component for the control treatment and the second toward treatment, as AP-SSF succeeded in increasing the percentage of milk fat. For Staphylococcus sp., Streptococcus sp. and Total coliform differences (P < 0.05) in favor of the treatment were achieved AP-SSF and decreased the CFU / mL for Salmonella sp. while there was no difference (P > 0.05). Volatile fatty acids showed statistical difference (P < 0.05) for Acetic, Propionic, and Butyric acids. AP-SSF treatment for the rest of the parameters ruminal pH, ammonia, and protozoa did not show any significant difference (P > 0.05) between treatments. Concluded that it is possible to incorporate AP-SSF as a protein ingredient in diets of dairy cows in early lactation because some variables improved and showed no adverse effects in any of the variables evaluated.
Ciudades inteligentes como nuevos desarrollos urbanos: sostenibilidad, conocimiento y comunicación
Authors: Ramírez Rosete Norma Leticia , González  González María Jesús , Tapia Carlín Rebeca Elena
Published: June 2023

La demanda acelerada de espacio para los nuevos desarrollos urbanos e industriales ha generado grandes aglomeraciones descontroladas como tejido urbano anónimo o indiferenciado, que al ser procesos urbanos modernos solo saben crecer, pero carecen de “inteligencia” para organizar su desarrollo. De esta manera el ser una Smart City conlleva un coste económico alto, imposible en una economía, donde no se discute el beneficio de una inversión sino la eficacia con la que se genera, para volver a desplazar los recursos a otro punto. La presente investigación desarrolla un análisis acerca de la percepción de alumnos españoles y mexicanos de licenciatura y posgrado, respecto a las características de una smart city, con el objetivo de aportar referentes para nuevos proyectos urbanos y generar cambios en las ciudades actuales, con la finalidad de convertirlas en lugares más humanos, sostenibles e inteligentes.

Published: June 2023

The objective of this research was the morphomolecular identification of species of the genus Fusarium associated with native and commercial maize genotypes in municipalities of Puebla and Morelos, Mexico, as well as to describe the socioeconomic and cultural importance of maize cultivation. Fusarium species were isolated from grains and stem cuttings with purple, brown, and dark brown pigmentations. They were identified morphomolecularly by using taxonomic keys and the Dinocapture 2.0 software, and by DNA extraction by the CTAB method and amplification of the ITS1 and ITS4 region by PCR. Four species were identified: Fusarium equiseti, Fusarium verticillioides, Fusarium incarnatum and Fusarium napiforme with an identity greater than 98%. The genotypes with the highest incidence of Fusarium spp. were: Pioneer 30F35 in San Miguel, Teotlalco, Puebla by F. verticillioides (A2). The genotypes with the lowest incidence were: Shark from Tetelilla, Morelos by F. incarnatum (A1), F. verticillioides (A6) and F. napiforme (A7). Maize is the main food in many locations in Mexico, however, due to the high consumption of this grain and its derivatives, as well as the high consumption of meat presumably fed with this grain, it could represent a route of ingestion of mycotoxins.
Validation of the PHQ-15 questionnaire version for the Mexican population to assess psychosomatic symptoms
Authors: Bravo Doddoli Andrea , Díaz Rivera Paola Eunice
Published: June 2023

Psychosomatic symptoms are physical manifestations of psychological origin that are not adequately explained by organic causes. For this reason, it is difficult to differentiate them from other conditions, so health sciences must consider their diagnosis and research on them a priority. The PHQ-15 (Patient Health Questionnaire) is an instrument that allows its diagnosis through a list of 15 psychosomatic symptoms. The purpose of this research was to validate the PHQ-15 for the Mexican adult population, obtaining indicators of reliability, construct, and convergent validity. First, the instrument was translated and culturally adapted. This version was evaluated by mental health specialists and doctors. The PHQ-15 and the Hospital Anxiety and Depression Scale (HADS) were applied to 420 Mexican participants through an online survey. A Confirmatory Factor Analysis was performed that rectified the unifactorial structure. The results showed acceptable fit indicators and a significant contribution of all the reagents to the model. The correlations between the PHQ-15 and the HADS showed a directly proportional relationship between psychosomatic symptoms with depression and anxiety, which provides evidence of convergent validity. Regarding internal consistency, it showed adequate levels of reliability.
Research on water quality spatiotemporal forecasting model based on ST-BIGRU-SVR neural network
Authors: Gai Rongli , Yang Jiahui
Published: June 2023

With the serious deterioration of the water environment, accurate prediction of water quality changes has become a topic of increasing concern. To further improve the accuracy of water quality prediction and the stability and generalization ability of the model, we propose a new water quality spatiotemporal forecast model to predict future water quality. To capture the spatiotemporal characteristics of water quality pollution data, the three sites (station S1, station S2, station S4) with the highest temperature time series concentration correlation at the experimental sites were first extracted to predict the water temperature at station S1, and 17,380 records were collected at each monitoring station, and the spatiotemporal characteristics were extracted by BiGRU-SVR network model. This paper's prediction test is based on the actual water quality data of the Qinhuangdao sea area in Hebei province from 2 September to 26 September 2013 and compared with other baseline models. The experimental results show that the proposed model is better than other baseline models and effectively improves the accuracy of water quality prediction, and the mean absolute error (MAE), root mean square error (RMSE), and coefficient of determination (R2) are 0.071, 0.076, and 0.957, respectively, which have good robustness.
Synthesis of Dendrimer Conjugates with Naproxen and their Anticancer Activity
Authors: Castillo-Rodríguez Irving Osiel , Ramírez-Ápan Teresa , Martínez-García Marcos
Published: June 2023

Here we report the easy synthesis of dendrimer conjugates with four and eight
naproxen moieties at the periphery. The synthesis involved two steps protection-deprotection
sequence joined with triethylene glycol. A comparison was made between the cytotoxicity of
dendron-naproxen conjugates and that of G1.0 G2.0 dendrimer-naproxen conjugates. Cytotoxicity
studies showed that dendron conjugates were toxic towards all cancer cell lines studied,
and their toxicity was significantly lower than that of dendrimer conjugates. However,
dendrimer conjugates showed higher cytotoxicity and selectivity against K-562 and SKLU-
1 than dendron conjugates.
