El equilibrio entre el derecho a la salud y otros derechos económicos, sociales y culturales en tiempos de pandemia,

The outbreak of an epidemic or pandemic is always a time of threat, emergency and uncertainty. When people's health and lives are put at risk, urgent and coordinated responses are required from state actors at national, regional and global levels that have the potential to contain the pandemic and prevent its spread. From this emergency situation and from continuous changes in norms that impose new restrictions, obligations and responsibilities on citizens, a dilemma arises about the balance between the protection of the right to health and other economic, social and cultural rights.El estallido de una epidemia o una pandemia es siempre un momento de amenaza, emergencia e incertidumbre. Cuando la salud y la vida de las personas se pone en peligro se requieren respuestas urgentes y coordinadas por parte de los agentes estatales a nivel nacional, regional y global que tengan el potencial de contener la pandemia y evitar su propagación. De esta situación de emergencia y de continuos cambios en las normas que imponen nuevas restricciones, obligaciones y responsabilidades a los ciudadanos, se deriva dilema sobre el equilibrio entre la protección del derecho a la salud y otros derechos económicos, sociales y culturales

La autoestima en la expresión oral

This research work focused on determining the relationship between self-esteem and oral expression of the students of the Faculty of Education of the Universidad Nacional Mayor de San Marcos (UNMSM). The objective was to analyze how students' self-esteem affects their ability to speak. A basic type methodology was used, specifically a non-experimental design of causal level, since a causal relationship is identified between the variables studied. The technique used to collect data was the survey, through an instrument designed to assess both self-esteem and oral expression. The sample consisted of a total of 90 students, randomly selected during the period from July to August 2022. The results obtained from the investigation showed a significant p value (p < 0.05), specifically a p value equal to 0.000. Consequently, the null hypothesis was rejected and the alternative hypothesis was accepted, indicating that there is a significant relationship between self-esteem and oral expression. In other words, it was observed that higher self-esteem is related to better oral expression. The methodology used in this study is basic, non-experimental design at the causal level, because one of the variables affects the other. The technique used was the survey, using an instrument to capture both self-esteem and oral expression. The sample was made up of 100 students, the sample size chosen was considering 50% of the total number of students of the Faculty of Education of the specialty of Primary and Initial Education and represents a significant number to determine the information of the students with respect to their self-esteem and its relationship with oral expression. The sampling was carried out by random selection with the students who attend the Faculty of Education of the specialty of Primary and Initial Education during the period between July and August 2022.           The main results of the research is the existence of a significant positive incidence of self-esteem in oral expression, in this way the optimal development of these skills is essential to increase the levels of Teaching Performance and thus improve the quality of Education. in Peru.Este trabajo de investigación se centró en determinar la relación entre la autoestima y la expresión oral de los estudiantes de la Facultad de Educación de la Universidad Nacional Mayor de San Marcos (UNMSM).

Lack of maintenance of motorway fences works against their intended purpose with potential negative impacts on protected species

Linear infrastructure intrusions into natural ecosystems, such as motorways and high-speed railways, causes direct loss of habitat but also impacts fauna through collisions. Wildlife road mortality is well documented and extensive conservation legislation exists in many countries to minimise the negative impact of these infrastructures. However, although these measures are implemented because of legislation, these structures are often not adequately maintained. Here we present data on the functionality of perimeter fences along two motorways in Malaga province (southern Spain) erected to prevent collisions with the common chameleon (Chamaeleo chamaeleon). We sampled the fences along the 14 km of the two motorways included in the 17 1 × 1 km squares of the study area. Our results show that the reptile fence is permeable throughout at those points where the metal sheeting was absent and where the vegetation had overgrown around the fence, hence allowing chameleons to cross. Given our results, we conclude that this situation is likely to be similar in other regions of Spain and in other countries. This is because construction/concessionary companies do not consider the environmental impact of construction projects in the medium and long term, and environmental authorities do not ensure that companies comply with the legislation

Importancia agroecológica del coyul (Acrocomia mexicana Karw. ex Mart.)

Acrocomia mexicana Karw. ex Mart. es una especie que se extiende desde el Pacífico mexicano hasta Centro y Sudamérica. El fruto (coyul) es apreciado desde la época prehispánica, sin embargo, su consumo ha disminuido frente a otros frutos nativos y así como de los introducidos con mayor aceptación en el mercado. Se realizó un estudio en San Blas, Nayarit, México, en el que se llevó a cabo la caracterización de un agroecosistema típico donde se explotan poblaciones silvestres y cultivadas de coyul de forma tradicional y se resaltó la importancia económica, ecológica y cultural de la especie. Asimismo, se realizó la caracterización fisicoquímica del fruto; la pulpa y la semilla son fuente principalmente de grasas. De esta especie se pueden obtener subproductos tales como aceites comestibles, alimento para ganado, artesanías, entre otros; igualmente se exponen alternativas de uso llevadas a cabo por otras regiones y países que puedan conducir a conservar espacios ecológicos y culturales

Chronic Inflammatory Responses to Microgel-Based Implant Coatings

Inflammatory responses to implanted biomedical devices elicit a foreign body fibrotic reaction that limits device integration and performance in various biomedical applications. We examined chronic inflammatory responses to microgel conformal coatings consisting of thin films of poly(N-isopropylacrylamide) hydrogel microparticles cross-linked with poly(ethylene glycol) diacrylate deposited on poly(ethylene terephthalate) (PET). Unmodified and microgel-coated PET disks were implanted subcutaneously in rats for 4 weeks and explants were analyzed by histology and immunohistochemistry. Microgel coatings reduced chronic inflammation and resulted in a more mature/organized fibrous capsule. Microgel-coated samples exhibited 22% thinner fibrous capsules that contained 40% fewer cells compared to unmodified PET disks. Furthermore, microgel-coated samples contained significantly higher levels of macrophages (80%) than unmodified PET controls. These results demonstrate that microgel coatings reduce chronic inflammation to implanted biomaterials

Reduced Acute Inflammatory Responses to Microgel Conformal Coatings

Implantation of synthetic materials into the body elicits inflammatory host responses that limit medical device integration and biological performance. This inflammatory cascade involves protein adsorption, leukocyte recruitment and activation, cytokine release, and fibrous encapsulation of the implant. We present a coating strategy based on thin films of poly(N-isopropylacrylamide) hydrogel microparticles (i.e. microgels) cross-linked with poly(ethylene glycol) diacrylate. These particles were grafted onto a clinically relevant polymeric material to generate conformal coatings that significantly reduced in vitro fibrinogen adsorption and primary human monocyte/macrophage adhesion and spreading. These microgel coatings also reduced leukocyte adhesion and expression of pro-inflammatory cytokines (TNF-alpha, IL-1 beta, MCP-1) in response to materials implanted acutely in the murine intraperitoneal space. These microgel coatings can be applied to biomedical implants as a protective coating to attenuate biofouling, leukocyte adhesion and activation, and adverse host responses for biomedical and biotechnological applications

Observation of a Griffiths-like phase in the paramagnetic regime of ErCo_2

A systematic x-ray magnetic circular dichroism study of the paramagnetic phase of ErCo2 has recently allowed to identify the inversion of the net magnetization of the Co net moment with respect to the applied field well above the ferrimagnetic ordering temperature, Tc. The study of small angle neutron scattering measurements has also shown the presence of short range order correlations in the same temperature region. This phenomenon, which we have denoted parimagnetism, may be related with the onset of a Griffiths-like phase in paramagnetic ErCo2. We have measured ac susceptibility on ErCo2 as a function of temperature, applied field, and excitation frequency. Several characteristics shared by systems showing a Griffiths phase are present in ErCo2, namely the formation of ferromagnetic clusters in the disordered phase, the loss of analyticity of the magnetic susceptibility and its extreme sensitivity to an applied magnetic field. The paramagnetic susceptibility allows to establish that the magnetic clusters are only formed by Co moments as well as the intrinsic nature of those Co moments

In vitro PGPR properties and osmotic tolerance of different Azospirillum native strains and their effects on growth of maize under drought stress

Osmotic variations in the soil can affect bacterial growth diminishing the number ofinoculated bacteria. In a scenario of water deficit having tolerant bacteria would bebeneficial to achieve a better response of the plant to stress. Thus, selection of moreresistant bacteria could be useful to design new inoculants to be used in arid zones. In thissense, a group of Azospirillum isolates deposited in INTA collection was characterized inorder to select strains tolerant to osmotic stress. The results obtained demonstrated that Az19 strain has similar in vitro PGPR characteristics to Az39, the most used strain inArgentina for inoculants industries, with the advantage of a better tolerance to osmotic andsalt stress. Inoculation of maize plants with this strain resulted in a better response againstwater deficit compared to Az39 strain, encouraging us to further study the behavior of thisstrain in greenhouse and field trials in view of developing new inoculants suitable for areaswith water deficit.Fil: García, Julia E..

In Vitro Evaluation of the Biological Effects of ACTIVA Kids BioACTIVE Restorative, Ionolux, and Riva Light Cure on Human Dental Pulp Stem Cells

This study aimed to analyze the biological effects of three new bioactive materials on cell survival, migration, morphology, and attachment in vitro. ACTIVA Kids BioACTIVE Restorative (Pulpdent, Watertown, MA, USA) (Activa), Ionolux (Voco, Cuxhaven, Germany), and Riva Light Cure UV (SDI, Bayswater, Australia) (Riva) were handled and conditioned with a serum-free culture medium. Stem cells from human dental pulp (hDPSCs) were exposed to material extracts, and metabolic activity, cell migration, and cell morphology were evaluated. Cell adhesion to the different materials was analyzed by scanning electron microscopy (SEM). The chemical composition of the materials was evaluated by energy-dispersive X-ray (EDX). One-way analysis of variance followed by a Tukey test was performed (p < 0.05). Ionolux promoted a drastic reduction in metabolic activity and wound closure compared to the control (p < 0.05), whereas Activa induced adequate metabolic activity and cell migration. Moreover, SEM and immunofluorescence analysis showed abundant cells exposed to Activa. The materials showed different surface morphologies, and EDX spectra exhibited different peaks of C, O, Si, S, Ca, and F ions in glass ionomer cements. The results showed that Activa induced cell migration, cell attachment, and cell viability to a greater extent than Riva and Ionolux.The Spanish Net of Cell Therapy (TerCel), RETICS subprograms of the I+D+I 2013-2016 Spanish National Plan, and project “RD16/0011/0001” funded by the Instituto de Salud Carlos III to JMM and co-funded by the European Regional Development Fund supported this workS
