The service-learning disciplines can offer a unique opportunity for civic development in university students, as there is a large body of research that links it to values and civic attitudes including a vast number of ecological issues and citizen variables. Moreover, one should bear in mind that these students are future generations that will face many pressing social and environmental issues. Given the need to develop instruments to measure the impact of a service-learning methodology in university students’ values as well as civic attitudes, VAL-U is proposed. As the university can be considered a learning step prior to the professional field, the main objective of this study was to analyse the internal consistency and factor structure of the proposed VAL-U scale in the Spanish population. The scale confirmed acceptable psychometric properties. Furthermore, the results have shown high reliability and optimal goodness of fit. Promising results are offered to employ VAL-U as a valuable tool for assessing Values and Civic Attitudes Scale for Spanish-speaking University Students’ Service-Learning.
The transition from on-paper to on-screen reading seems to make it necessary to raise some considerations, as a greater attentional effort has been claimed for print texts than digital ones. Not surprisingly, most university students prefer this digital medium. This research aims to examine reading times by contextualizing this phenomenon into two processes: namely, word recognition and reading comprehension task on paper and on screen. Thus, two different tasks—counterbalanced into digital and print mediums—were carried out per each participant with a preference for a digital medium: a reading comprehension task (RCT) and a lexical decision task (LDT) after reading a specific story. Participants were slower reading print texts and no statistically significant differences were found in RCT accuracy. This result suggests that the task required more cognitive resources under the print medium for those with a worse comprehension performance in reading, and a more conservative pattern in digital RCT for those with a better performance.
Phytotherapy, based on medicinal plants, have excellent potential in managing several diseases. A vital part of the healthcare system is herbal medicines, consisting of therapeutic agents with high safety profile and no or least adverse effects. Herbs or medicinal plants show anticancer, antioxidant, and gene-protective activity, which is useful for pharmaceutical industries. In vitro, the extract of antioxidant compounds prevents the growth of colon and liver cancer cells, followed by a dose-dependent method. The screening of extracts is done by using in vitro models. Reactive oxygen species (ROS) and free radicals lead to diseases based on age which promotes oxidative stress. Different types of ROSs available have central roles in the normal physiology and functioning of processes. Herbal or traditional plant medicines have rich antioxidant activity. Despite the limited literature on the health effect of herbal extract or spices. There are many studies examining the encouraging health effects of single phytochemicals instigating from the medicinal plant. This review provides a detailed overview on herbal antioxidants and how application of nanotechnology can improve its biological activity in managing several major diseases, and having no reported side effects.
Protein nanomaterials are well-defined, hollow protein nanoparticles comprised of virus capsids, virus-like particles, ferritin, heat shock proteins, chaperonins and many more. Protein-based nanomaterials are formed by the self-assembly of protein subunits and have numerous desired properties as drug-delivery vehicles, including being optimally sized for endocytosis, nontoxic, biocompatible, biodegradable and functionalized at three separate interfaces (external, internal and intersubunit). As a result, protein nanomaterials have been intensively investigated as functional entities in bionanotechnology, including drug delivery, nanoreactors and templates for organic and inorganic nanomaterials. Several variables influence efficient administration, particularly active targeting, cellular uptake, the kinetics of the release and systemic elimination. This review examines the wide range of medicines, loading/release processes, targeted therapies and treatment effectiveness.
Nanotechnology is an arena of exploration and innovation concerned with building things generally, advancing resources and devices based on highly specific and superior nanomaterials with unmatched properties dependent on their morphology and diameter. 2D materials such as graphene have unique properties and applications varying from imaging, delivery of drugs, and theranostics of diseases. Each 2D material, ranging from the graphene family, MXenes, chalcogenides, and 2D oxides, have a unique potential based on their shape and morphology. In addition, 2D materials have intriguing physiochemical characteristics, increased aspect ratio and associated increased reactivity that make them an ideal contender in multiple applications. This review aims to answer the existing knowledge gaps in various 2D materials having interdisciplinary roles. We have presented a brief overview of the 2D materials, followed by their synthesis methods and techniques. We have also highlighted the different characterization methods used to characterise various 2D materials. Next, we performed an in-depth analysis of the potential toxicities of 2D materials to assess their risks in multiple applications. Lastly, we conclude our review by presenting the challenges and future perspectives of 2D materials as promising forerunners of science and technology.
In the present study, D. magna individuals were exposed to several sublethal prochloraz concentrations (87, 130, 170, 230 and 380 μg/L) for 21 days according to; the previous acute toxicity results. The fungicide effects on reproduction, survival, individual size, and growth population rate were evaluated after an exposure of 21 days, and no changes were observed compared to the control group. On the other hand, F1 generation neonates were collected and their external morphology evaluated; to estimate if the fungicide concentrations used induced effects during oogenesis and; embryogenesis processes. Neonates from parents which were previously exposed to 170 μg/L and higher concentrations were malformed since 16-d of exposure onward. All animals presented the same malformation: asymmetrical shell morphology and separated valves that did not cover the complete animal body regardless of the; concentration. The biochemical parameters tested in the broodstock were cholesterol, triglycerides, glucose and LDH activity. At the end of the chronic exposure experiment, cholesterol and triglycerides remained unaltered while glucose and the LDH enzyme levels increased significantly. The results of the present work showed a direct effect of; prochloraz on D. magna individual growth, along with mobilization of some; biochemical intermediate metabolism. A daphnid stress response as a result of the fungicide presence in the medium could be an explanation for the metabolic disorders. On the other hand, the F1 malformed neonates found in the present study suggested an effect of prochloraz among different daphnid generations and more studies would be necessary in this field.
A new biodegradable semi-interpenetrated polymer network (semi-IPN) of two US Food and Drug Administration approved materials, poly(3-hydroxybutyrate-co-3-valerate) (PHBV) and calcium alginate (CA) was engineered to provide an alternative strategy to enhance the poor adhesion properties of CA. The synthesis procedure allows the additional incorporation of 10 % w/w of graphene nanoplatelets (GNPs), which have no cytotoxic effect on human keratinocytes. This quantity of multilayer graphene provides superior antiviral activity to the novel semi-IPN against a surrogate virus of SARS-CoV-2. Adding GNPs hardly affects the water absorption or electrical conductivity of the pure components of CA and PHBV. However, the semi-IPN's electrical conductivity increases dramatically after adding GNP due to molecular rearrangements of the intertwined polymer chains that continuously distribute the GNP nanosheets, This new hydrophilic composite biomaterial film shows great promise for skin biomedical applications, especially those that require antiviral and/or biodegradable electroconductive materials.
The aim of this Special Edition is to highlight the exponential work performed in the field of antimicrobial material research from the beginning of the current COVID-19 pandemic [...]
Background Depression and low perceived social support (PSS) have been found to deleteriously affect quality of life (QoL) among myocardial infarction (MI) survivors. The complex relationship between these variables has not been assessed. We wanted to assess first the prevalence of depression among MI survivors and whether depression mediates the effect of PSS on QoL and, second, whether the physical and social domains of QoL mediated the effect of depression and PSS on the emotional domain. This cross-sectional study was done among MI survivors using Cardiac Depression Scale, MacNew Quality of Life After Myocardial Infarction Questionnaire and Multidimensional Scale of Perceived Social Support to assess for depression, QoL and PSS respectively. Results A total of 103 MI survivors were included in the study, and the mean age was 59.66 (± 10.42) years. Depression was found in 21.36% of the participants. The indirect effect of PSS on QoL with depression as a mediator was significant (b = 0.15, p < 0.001, 95% CI = 0.12, 0.18). The direct effect of PSS on QoL controlling for depression was also significant (b = 0.05, p < 0.001, 95% CI = 0.02, 0.07). Depression as a mediator in the relationship explained 75.3% of the effect of PSS on QoL. PSS and depression did not have a significant direct effect on emotional QoL, but it became significant when the physical and social domains were included in the model. The total indirect effects of PSS and depression on emotional QoL were b = 0.16, p < 0.001, 95% CI = 0.05, 0.17 and b = − 0.05, p < 0.001, 95% CI = − 0.06, − 0.03, respectively. Conclusion Depression and poor PSS impair physical and social domains, which impairs the emotional domain of QoL; as such, overall QoL is undermined. As limited physical and social activity because of depression and poor PSS may increase the risk of further cardiovascular events, a holistic approach which includes mental health care is warranted.
A study was made of the effect of the PROMUFRA multicomponent frailty program upon physical frailty, kinanthropometry, pain and muscle function parameters in frail and pre-frail community-dwelling older people. Eighty-one participants were randomly allocated to the intervention group (IG) or control group (CG). The IG performed PROMUFRA for 20 weeks, using six strength exercises with three series of 8-12 repetitions until muscular failure, and seven myofascial exercises, with one set of 10 repetitions. The CG continued their routine. The frailty criteria number (FCN), kinanthropometric parameters and muscle function were measured at baseline and after the program. Between-group differences were found in the interaction for FCN, muscle mass, fat mass, skeletal muscle mass index, knee flexion range of motion (ROM), hip flexion with knee straight ROM, maximum isometric knee extension, maximum isotonic knee extension, maximum leg press and hand grip strength., and also on post-intervention frailty status. The IG showed a statistical trend towards decreased pain. In conclusion, the PROMUFRA program is a potential training approach that can bring benefits in physical frailty status, body composition, ROM and muscle function among frail or pre-frail community-dwelling older people.
Resumen Introducción La esclerosis múltiple (EM) es una enfermedad neurodegenerativa caracterizada por daños en la vaina de mielina que recubre las neuronas, y que muestra diferencias entre hombres y mujeres en cuanto a la susceptibilidad y progresión de la enfermedad relacionada a su vez con la capacidad funcional y calidad de vida. Objetivos Conocer las diferencias en función del género, valorando la capacidad funcional, y fuerza muscular y motricidad fina de las extremidades superiores de pacientes con EM. Material y métodos Estudio cuantitativo, descriptivo de carácter transversal que contó con una muestra poblacional de 51 pacientes diagnosticados de EM, a los que se valoró la capacidad funcional (escala DASH), el equilibrio estático, dinámico (escala Berg) y percibido (escala ABC); fuerza (Jamar y dinamómetro); y la motricidad fina de las manos (NHPT). Resultados La muestra consistió en 15 hombres y 36 mujeres, con una edad media de 47 ± 12 años. No se observaron diferencias en la capacidad funcional DASH (p = 0,616). Además, se observó en los hombres mayor fuerza en pinza (p < 0,001) y mayor fuerza en tríceps (p < 0,05) de ambos brazos. En cuanto a la motricidad fina, esta fue mejor en las mujeres tanto en la mano dominante como en la no dominante (p < 0,05). Conclusiones A pesar de no observarse diferencias funcionales por sexo, sí existen diferencias en los parámetros de fuerza en pinza y fuerza en el tríceps, que es mayor en hombres; y en destreza manual de ambas manos, que es mejor en las mujeres.
The efficacy of chemotherapy depends on the tumor microenvironment. This microenvironment consists of a complex cellular network that can exert both stimulatory and inhibitory effects on tumor genesis. Given the increasing interest in the effectiveness of cannabis, cannabinoids have gained much attention as a potential chemotherapy drug. Cannabinoids are a group of marker compounds found in Cannabis sativa L., more commonly known as marijuana, a psychoactive drug used since ancient times for pain management. Although the anticancer potential of C. sativa, has been recognized previously, increased attention was generated after discovering the endocannabinoid system and the successful production of cannabinoid receptors. In vitro and in vivo studies on various tumor models have shown therapeutic efficiency by modifying the tumor microenvironment. However, despite extensive attention regarding potential therapeutic implications of cannabinoids, considerable clinical and preclinical analysis is needed to adequately define the physiological, pharmacological, and medicinal aspects of this range of compounds in various disorders covered in this review. This review summarizes the key literature surrounding the role of cannabinoids in the tumor microenvironment and their future promise in cancer treatment.
AimThe functional prognosis of patients after coma following either cardiac arrest (CA) or acute structural brain injury (ABI) is often uncertain. These patients are associated with high mortality and disability. N20 and N70 somatosensory evoked potentials (SSEP) are used to predict prognosis. We evaluated the utility of SSEP (N20–N70) as an early indicator of long-term prognosis in these patients.Methods This was a retrospective cohort study of patients (n = 120) admitted to the intensive care unit (ICU) with a diagnosis of coma after CA (n = 60) or ABI (n = 60). An SSEP study was performed, including N20 and N70 at 24–72 h, after coma onset. Functional recovery was assessed 6–12 months later using the modified Glasgow scale (mGS). The study was approved by our local research ethics committee.ResultsIn the CA and ABI groups, the absence of N20 (36% of CA patients and 41% of ABI patients; specificity = 100%) or N70 (68% of CA patients and 78% of ABI patients) was a strong indicator of poor outcome. Conversely, the presence of N70 was an indicator of a good outcome (AC: specificity = 84.2%, sensitivity = 92.7%; ABI: specificity = 64.2% sensitivity = 91.3%).Conclusion Somatosensory evoked potentials are useful early prognostic markers with high specificity (N20) and sensitivity (N70). Moreover, N70 has additional potential value for improving the prediction of good long-term functional outcomes.Clinical Trial Registration:[https://clinicaltrials.gov/], identifier [2018/01/001].
La despenalización del aborto basada en una corriente reduccionista del pensamiento favorece la destrucción de embriones, produciendo secuelas permanentes en la salud e inclusive la pérdida de la vida de la madre. En este artículo se analiza el conocimiento de los habitantes de Aguascalientes, México, sobre la despenalización del aborto y los efectos de éste en la madre, en apoyo a la iniciativa de la Constitución Política de dicho Estado. La metodología es cuantitativa, no experimental, transeccional y descriptiva-explicativa. Los hallazgos afirman que el comienzo de lvida humana se gesta en la fecundación; que el nonato es sujeto de derechos equivalentes a un ser humano nacido y que debe protegerse su vida, negando el aborto porque refuta el derecho a la vida.
Background Meaning-Centered Psychotherapy (MCP) is effective in improving meaning in life, hope, optimism, self-efficacy, well-being, and quality of life, and in reducing stress in people with cancer. However, all the studies on the application of MCP in cancer patients have been carried out in Anglo-Saxon samples. Therefore, it is necessary to adapt and verify the efficacy of MCP in populations that speak languages other than English, such as Spanish. Moreover, to expand the data supporting the efficacy of MCP for cancer patients, it would be necessary to compare MCP to other active therapies such as Cognitive Behavioral Therapy (CBT). Methods The aims of the proposed study are: the first objective is to verify the efficacy of the MCP intervention for Spanish participants with cancer in a randomized control trial (RCT) comparing it to CBT. The second objective is to analyze the feasibility and acceptance of MCP in Spanish participants with cancer. The third objective is to analyze whether the changes produced in the meaning in life dimensions (presence, search, comprehension, purpose, and mattering) will predict changes in anxiety, depression, quality of life, etc. Our research team adapted MCP for Spanish participants with cancer. This paper presents the study protocol. The study design consists of a two-arm RCT with two conditions: MCP and CBT, where participants will be randomized to one of the two groups. Eligible participants will be adults with stage I, II, and III cancer who were treated with curative intent and had completed their main medical treatment (surgery, radiotherapy, or chemotherapy). Participants will be assessed at pretreatment, post-treatment, and 6-month follow-up. The intention-to-treat principle will be used when analyzing data, using mixed-effects models with full information and maximum likelihood estimation. Discussion This study will provide results that confirm the efficacy of the MCP in Spanish participants with cancer.

MOTS-c (mitochondrial open reading frame of the 12 S rRNA-c) is a newly discovered peptide that has been shown to have a protective role in whole-body metabolic homeostasis. This could be a consequence of the effect of MOTS-c on muscle tissue. Here, we investigated the role of MOTS-c in the differentiation of human (LHCN-M2) and murine (C2C12) muscle progenitor cells. Cells were treated with peptides at the onset of differentiation or after myotubes had been formed. We identified in silico a putative Src Homology 2 (SH2) binding motif in the YIFY region of the MOTS-c sequence, and created a Y8F mutant MOTS-c peptide to explore the role of this region. In both cellular models, treatment with wild-type MOTS-c peptide increased myotube formation whereas treatment with the Y8F peptide did not. MOTS-c wild-type, but not Y8F peptide, also protected against interleukin-6 (IL-6)-induced reduction of nuclear myogenin staining in myocytes. Thus, we investigated whether MOTS-c interacts with the IL-6/Janus kinase/ Signal transducer and activator of transcription 3 (STAT3) pathway, and found that MOTS-c, but not the Y8F peptide, blocked the transcriptional activity of STAT3 induced by IL-6. Altogether, our findings suggest that, in muscle cells, MOTS-c interacts with STAT3 via the putative SH2 binding motif in the YIFY region to reduce STAT3 transcriptional activity, which enhances myotube formation. This newly discovered mechanism of action highlights MOTS-c as a potential therapeutic target against muscle-wasting in several diseases.
Introduction The increased synthesis of CA125 in mesothelial cells is connected with pathophysiological processes, also present in sepsis, that link inflammation with systemic congestion. We propose to evaluate serum levels of this biomarker in patients with sepsis and to study its association with the severity and evolution of the disease. Methods Longitudinal retrospective observational study, which included 126 patients admitted to an Intensive Care Unit with sepsis criteria. The main variables analyzed were: CA125 values for 7 days, the variation of its levels according to the source of infection (abdominal, pulmonary, nephrourinary and others), sepsis, septic shock, APACHE-II score and mortality. Results CA125 levels remained elevated throughout the study period. The abdominal focus presented higher mean levels of CA125 (62 ± 55.5 U/mL; P = 0.001) and were higher in non-survivors (77.2 U/mL; interquartile range 35.9−118.5; P = 0.0273). CA125 levels > 35 U/mL throughout the weal had an independently effect on the evolution (relative risk [RR] 3.1; 95% confidence interval [CI] 1.6–6.2; P = 0.001) and the elevated mean value of CA125 was also associated with mortality (RR 1.004; 95% CI 1.001–1.005; P = 0.0001). Conclusions Septic patients presented high levels of CA125 on the study days, being higher in abdominal infections. In our study, serial determination of CA125 is a prognostic marker of mortality independent of age, origin of infection or severity.
Las brujas de Barahona se han convertido en un lugar común que ha pervivido en el ideario colectivo. El origen de la creencia en estas mujeres infanticidas, que maltratan a los vecinos, pactan con el diablo, se untan, vuelan y acuden a reuniones en los campos de Barahona, se cifra en un proceso iniciado en 1526 contra Juana de Morillas y en 1527 contra Francisca la Ansarona y Quiteria de Morillas. Los crímenes contra estas mujeres cristalizan en historias que olvidan a las protagonistas del brote brujeril y se refieren a una masa informe de féminas a la que se aludirá en diversos textos de los siglos XVIII y XIX. Se encuentran menciones a estas brujas en un pronóstico de Torres Villarroel, "Las brujas del campo de Barahona" (1795); en la prensa de ambas centurias, en las "Cartas marruecas" de José Cadalso (1789), en las anotaciones de Fernández de Moratín a la relación del "Auto de Fe de Logroño de 1610" (1811) y en un relato anónimo "Las brujas de Barahona y la castellana de Arbaizal" (1841), que destaca especialmente por su extensión y la atención que dedica a estas mágicas. En este trabajo se realizará un recorrido por estos textos y se determinará en qué medida existe una conexión con el proceso histórico que se recoge en los legajos 96 n.o 1425 y 99 n.o 1441.
Japanese Black (Wagyu) cattle produce high-quality beef. However, whether Wagyu steers can be profitably raised under conditions different than the traditional Japanese ones remains unclear. From 2018 to 2020, we raised 262 Wagyu purebred steers, 103 Wagyu-by-Angus (Wangus) crossbred steers, and 43 Angus-by-European (ACL) crossbred steers on a Spanish farm with high welfare standards and a locally sourced, high-olein diet. Factors and factors' interactions impacting steer growth were analyzed using generalized linear models. ACL steers grew faster than the other two groups, with Wangus showing intermediate fattening and muscle development. Average daily weight gains (kg/day) were 0.916 for Wagyu, 1.046 for Wangus, and 1.293 for ACL during the weaning to growing period, and 0.628 for Wagyu, 0.64 for Wangus, and 0.802 for ACL during the growing to fattening phase. ACL showed the lowest marbling rates. Wagyu and Wangus usually showed higher cholesterol, triglycerides, and high-density lipoprotein than ACL. ACL calves may experience greater stress at weaning, as suggested by higher glucose, lactate, and β-hydroxybutyrate than the other groups. The results suggest that Wagyu and Wangus steers showed adequate growth, health, and metabolic development in this type of production system, with Wagyu purebreds probably being more profitable than Wangus crossbreeds.
