Bacterias diazotroficas y solubilizadoras de fósforo aisladas de las especies forestles altoandinas colombianas Weinmannia tomentosa y Escallonia myrtilloides

Encenillo (Weinmannia tomentosa Lf) and pagoda (Escallonia myrtilloides Lf) are dominant native tree species that can be found in the forests of the complex Andean Guerrero (Cundinamarca, Colombia). Forty two phosphorus-solubilizing bacteria and 125 nitrogen-fixing strains were isolated from the rhizosphere of these trees, out of which the microbial strains presenting the best five results of dissolution of phosphate and acetylene reduction by plant species were selected. The diazotrophic strains selected were identified as close to Enterobacter gergoviae, Alcaligenes sp. (E13C and E12E strains), Enterobacter sp. (E14C.2 strain), Pseudomonas sp., Sphingomonas sp., Paenibacillus sp., Achromobacter sp., Flavobacterium adoratum, and Klebsiella pneumoniae, and as phosphate-solubilizingbacteria near to Pantoea agglomerans, Pantoea sp., Brevudimonas sp., Enterobacter sp. (E6C.1 strain), Burkholderia cepacia, Arthrobacter sp., Aeromicrobium sp., Corynebacterium sp., Pimelobacter sp. and Micrococcus sp. In order to perform preliminary in vivo tests with the chosen microorganisms, it was inoculated bacterial mixture to encenillo and pagoda seedlings and evaluated their longitudinal growth for three months under greenhouse conditions. The major averages were obtained with the inoculation of Enterobacter gergoviae and Pantoea sp. in encenillo seedlings (average increase of 51% and 57% greater than the controls without microbial inoculation and sterile molasses medium, respectively) and the mixture of all selected bacteria in pagoda (Stimulation of 16% and 32% compared to controls molasses and without bacterial inoculation, respectively). The results showed that all the combinations using microbial inocula significantly stimulated longitudinal growth (Duncan multiple range test P<0.05). The synergism shown by co-inoculation of diazotrophic bacteria and phosphate solubilizing bacteria indicate the potential of these microorganisms as plant growth promoters and biofertilizers.El encenillo (Weinmannia tomentosa L.f) y la pagoda (Escallonia myrtilloides L.f) son especies forestales nativas predominantes en bosques altoandinos del complejo Guerrero (Cundinamarca, Colombia). De la rizosfera de estos árboles se aislaron 42 bacterias solubilizadoras de fósforo y 125 fijadoras de nitrógeno, de las cuales se escogieron las cepas microbianas que presentaron los cinco mejores resultados de disolución de fosfato y reducción de acetileno por cada especie vegetal. Las cepas diazotróficas escogidas se identificaron como cercanas a Enterobacter gergoviae, Alcaligenes sp. (Cepas E12E y E13C), Enterobacter sp (cepa E14C.2), Pseudomonas sp., Sphingomonas sp., Paenibacillus sp., Achromobacter sp., Flavobacterium adoratum y Klebsiella pneumoniae; y como solubilizadoras de fósforo a Pantoea agglomerans, Pantoea sp., Brevudimonas sp., Enterobacter sp. (Cepa E6C.1), Burkholderia cepacia, Arthrobacter sp., Aeromicrobium sp., Corynebacterium sp., Pimelobacter sp. y Micrococcus sp. Se realizaron ensayos preliminares in vivo con los microorganismos escogidos y se inocularon diferentes combinaciones bacterianas en plántulas de encenillo y pagoda. Se evaluó el crecimiento longitudinal durante tres meses bajo condiciones de invernadero. Los mayores promedios se obtuvieron con la inoculación de Enterobacter gergoviae y Pantoea sp., en plántulas de encenillo (incremento promedio de 51% y 57% más que los controles sin ninguna inoculación microbiana y medio melaza estéril, respectivamente) y con la mezcla de todas las bacterias escogidas en pagoda (estimulación de 16% y 32%, con respecto a los controles melaza y sin inoculación bacteriana, respectivamente). Todas las combinaciones microbianas utilizadas estimularon significativamente el crecimiento longitudinal (prueba de Duncan P<0,05). El sinergismo mostrado por la co-inoculación de bacterias diazotróficas y solubilizadoras de fósforo indican el potencial de estos microorganismos como promotores de crecimiento vegetal y posibles biofertilizantes

Prognostic value of ACE I/D, AT1R A1166C, PAI-I 4G/5G and GPIIIa a1/a2 polymorphisms in myocardial infarction

Background: Coronary artery disease (CAD) has turned into a prevalent cause of morbi-mortality contributing some polymorphisms in the recurrence of major adverse cardiac events (MACE).Methods: Three hundred and fifty six patients with first myocardial infarction (MI) were followed up during a 60-month period to find out if ACE I/D, AT1R A1166C, PAI-I 4G/5G and GPIIIa a1/a2 polymorphisms, in combination with other classical cardiovascular risk factors, can contribute to the relapse of MACE.Results: Two hundred and eighty five (80.1%) men and 71 (19.9%) women were followed up after first MI. The primary clinical endpoint, a composite of MACE, was reached in 106 (29.8%) patients. In the Cox univariate survival analysis those risk factors influencing a poorer prognosis were age (p = 0.004), a positive family history of CAD (p = 0.007), diabetes (p = 0.004), smoking (p = 0.024), fibrinolytic therapy (p = 0.012) and having 2 or 3 vessels CAD (p = 0.046). Cox proportional hazards regression model showed that patients with the DD genotype had a 1.5 increased risk of having an unfavorable outcome when compared with No-DD genotype patients (RR 1.561, 95% CI 1.048–2.326, p = 0.028) and that patients with the ACE DD genotype plus the AT1R No-AA genotype, the GPIIIa No-a1a1 genotype or a combination of both, had a twice higher risk than any other genotype of MACE in the follow-up (RR 1.978, 95% CI 1.286–3.043, p = 0.002).Conclusions: Patients with the ACE DD genotype plus 1 or 2 unfavorable genotypes, the AT1R No-AA, the GPIIIa No-a1a1 or a combination of both, have twice higher the risk of MACE during their clinical follow-up.

Use of the Xiaomi Mi Band for sleep monitoring and its influence on the daily life of older people living in a nursing home

[Abstract] Background: Lower quantity and poorer sleep quality are common in most older adults, especially for those who live in a nursing home. The use of wearable devices, which measure some parameters such as the sleep stages, could help to determine the influence of sleep quality in daily activity among nursing home residents. Therefore, this study aims to analyse the influence of sleep and its changes concerning the health status and daily activity of older people who lived in a nursing home, by monitoring the participants for a year with Xiaomi Mi Band 2. Methods: This is a longitudinal study set in a nursing home in [Details omitted for double-anonymized peer reviewed]. The Xiaomi Mi Band 2 will be used to measure biomedical parameters and different assessment tools will be administered to participants for evaluating their quality of life, sleep quality, cognitive state, and daily functioning. Results: A total of 21 nursing home residents participated in the study, with a mean age of 86.38 ± 9.26. The main outcomes were that sleep may influence daily activity, cognitive state, quality of life, and level of dependence in activities of daily life. Moreover, environmental factors and the passage of time could also impact sleep. Conclusions: Xiaomi Mi Band 2 could be an objective tool to assess the sleep of older adults and know its impact on some factors related to health status and quality of life of older nursing homes residents

Study for the design of a protocol to assess the impact of stress in the quality of life of workers

[Abstract] Background: Work stress is one of the most relevant issues in public health. It has a significant impact on health, especially the development of mental disorders, causing occupational imbalance. There is a growing interest in the development of tools with a positive effect on workers. To this end, wearable technology is becoming increasingly popular, as it measures biometric variables like heartbeat, activity, and sleep. This information may be used to assess the stress a person is suffering, which could allow the development of stress coping strategies, both at a professional and personal level. (2) Methods: This paper describes an observational, analytical, and longitudinal study which will be set at a research center in A Coruña, Spain. Various scales and questionnaires will be filled in by the participants throughout the study. For the statistical analysis, specific methods will be used to evaluate the association between numerical and categorical variables. (3) Discussion: This study will lay the foundation for a bigger, more complete study to assess occupational stress in different work environments. This will allow us to begin to understand how occupational stress influences daily life activity and occupational balance, which could directly enhance the quality of life of workers if the necessary measures are taken.This work is supported in part by some grants from the European Social Fund 2014–2020.

Study Protocol on the Validation of the Quality of Sleep Data from Xiaomi Domestic Wristbands

[Abstract] Background: Sleep disorders are a common problem for public health since they are considered potential triggers and predictors of some mental and physical diseases. Evaluating the sleep quality of a person may be a first step to prevent further health issues that diminish their independence and quality of life. Polysomnography (PSG) is the “gold standard” for sleep studies, but this technique presents some drawbacks. Thus, this study intends to assess the capability of the new Xiaomi Mi Smart Band 5 to be used as a tool for sleep self-assessment. (2) Methods: This study will be an observational and prospective study set at the sleep unit of a hospital in A Coruña, Spain. Forty-three participants who meet the inclusion criteria will be asked to participate. Specific statistical methods will be used to analyze the data collected using the Xiaomi Mi Smart Band 5 and PSG. (3) Discussion: This study offers a promising approach to assess whether the Xiaomi Mi Smart Band 5 correctly records our sleep. Even though these devices are not expected to replace PSG, they may be used as an initial evaluation tool for users to manage their own sleep quality and, if necessary, consult a health professional. Further, the device may help users make simple changes to their habits to improve other health issues as well.This work is supported in part by grants from the European Social Fund 2014–2020.

Oleanolic acid controls allergic and inflammatory responses in experimental allergic conjunctivitis

Producción CientíficaPollen is the most common aeroallergen to cause seasonal conjunctivitis. The result of allergen exposure is a strong Th2- mediated response along with conjunctival mast cell degranulation and eosinophilic infiltration. Oleanolic acid (OA) is natural a triterpene that displays strong anti-inflammatory and immunomodulatory properties being an active anti-allergic molecule on hypersensitivity reaction models. However, its effect on inflammatory ocular disorders including conjunctivits, has not yet been addressed. Hence, using a Ragweed pollen (RWP)-specific allergic conjunctivitis (EAC) mouse model we study here whether OA could modify responses associated to allergic processes. We found that OA treatment restricted mast cell degranulation and infiltration of eosinophils in conjunctival tissue and decreased allergen-specific Igs levels in EAC mice. Th2-type cytokines, secreted phospholipase A2 type-IIA (sPLA2-IIA), and chemokines levels were also significantly diminished in the conjunctiva and serum of OA-treated EAC mice. Moreover, OA treatment also suppressed RWP-specific Tcell proliferation. In vitro studies, on relevant cells of the allergic process, revealed that OA reduced the proliferative and migratory response, as well as the synthesis of proinflammatory mediators on EoL-1 eosinophils and RBL-2H3 mast cells exposed to allergic and/or crucial inflammatory stimuli such as RWP, sPLA2-IIA or eotaxin. Taken together, these findings demonstrate the beneficial activity of OA in ocular allergic processes and may provide a new intervention strategy and potential therapy for allergic diseases

Two Cu-Based Phosphonate Metal-Organic Frameworks as Efficient Water-Splitting Photocatalysts

[EN] Two novel three-dimensional metal-organic frameworks(MOFs)based on the photoactive pyrene tetraphosphonate ligand and copper(denoted as IEF-8 and IEF-9) have been hydrothermally synthesizedand fully characterized (XRD, FTIR, TGA, SEM, XPS, etc.). Their crystalstructures were unveiled by single-crystal X-ray diffraction. Remarkably,these materials exhibit coordinatively unsaturated copper (II) sites,free -PO3H2 and -PO3H acidic groups, and good thermal and chemical stability. Further,their optoelectronic characterization evidenced a photoresponse suitablefor photocatalysis. In this sense, the photocatalytic activity ofpyrene phosphonate MOFs was evaluated for the first time for the challenginghydrogen evolution reaction. In particular, IEF-8 exhibited a catalyticefficiency higher than that of the benchmarked Ti carboxylate photocatalystMIL-125-(Ti)-NH2, producing 1800 mu mol center dot g(-1) after 22 h under UV-vis irradiation in theabsence of any co-catalyst. Furthermore, this material presented goodreusability (at least up to 4 cycles), preserving its activity andstructural integrity.The authors acknowledge the Maria de Maeztu IMDEA Energy Institute, the M-ERA-NET C-MOF-cell project, the Retos Investigacion MOFSEIDON project (PID2019-104228RB-I00 funded by MCIN/AEI/10.13039/501100011033 and by the European Union, MICIU-AEI/FEDER, UE), and the H2-MOF project (TED2021-132092B-C21 funded by MCIN/AEI/10.13039/501100011033 and by the European Union NextGenerationEU/PRTR).

The interface: body extension or a space to communication. Metaphors that overlap

El artículo parte por reconocer las interacciones que establece el ser humano en distintos entornos; distingue al tercer entorno como espacio en donde los sujetos experimentan diversas actividades cotidianas, mediadas por las TIC que han generado transformaciones sociales. En el tercer entorno se asienta la interfaz, objeto de las reflexiones plasmadas en este espacio. En la primera parte de este texto se muestra la necesidad de precisar qué es la interfaz, entonces, la construcción colectiva del concepto se convierte en una provocación. Luego, se recorre el origen y la evolución del concepto, desde la década del sesenta hasta la actualidad. Se concluye que la comunicación es reconocimiento, no obstante se advierte que los lenguajes virtuales, las narrativas y los conocimientos pueden convertirse en otras formas de exclusión y de marginación que deben ser objeto de una profunda reflexión académica, en beneficio del avance democrático de las culturas.This article begins recognizing the interactions set up by human beings at different environments. It points out the third environment as the space where subjects experience different daily routines mediated by ICTs which have created social transformations. The interface is based in the third environment and is the matter discusses here. In the first part is clarified what the interface is; thus, the collective construction of the concept is a provocation. Then, it is explained the origin and evolution of the concept from 60’s to current days. It is conclude that communication is acknowledgement; however, it is advice that virtual languages, narratives, and knowledge can become in other ways of exclusion and marginalization that must be the subject of a thoughtful academic consideration which benefit the democratic advance of cultures

COYUNTURA ECONÓMICA, año 4, núm. 10, septiembre-diciembre 2022

La política social es parte fundamental de las políticas públicas, ya que nos acerca al desarrollo social al involucrar acciones estatales que tienen como objetivo transformar las condiciones de vida de cierto sector de la sociedad en áreas tales como educación, salud, vivienda y previsión social. En las últimas décadas, las políticas públicas focalizadas, aunque útiles para atacar los aspectos más urgentes de la pobreza, no han logrado la incorporación social masiva de todas las personas que así lo requieran debido al bajo crecimiento económico, las nuevas condiciones del mercado de trabajo, y las condiciones dejadas por la reciente pandemia. En el presente boletín titulado “La política social en el contexto de la pandemia en México” expertos en el tema analizarán el impacto que han tenido las políticas públicas actuales, desde distintos enfoques
