Growth dynamics of nanocolumnar thin films deposited by magnetron sputtering at oblique angles.

The morphology of numerous nanocolumnar thin films deposited by the magnetron sputtering technique at oblique geometries and at relatively low temperatures has been analyzed for materials as different as Au, Pt, Ti, Cr, TiO2, Al, HfN, Mo, V, WO3and W. Despite similar deposition conditions, two characteristic nanostructures have been identified depending on the material: a first one defined by highly tilted and symmetric nanocolumnar structures with a relatively high film density, and a second one characterized by rather vertical and asymmetric nanocolumns, with a much lower film density. With the help of a model, the two characteristic nanostructures have been linked to different growth dynamics and, specifically, to different surface relaxation mechanisms upon the incorporation of gaseous species with kinetic energies above the surface binding energy. Moreover, in the case of Ti, a smooth structural transition between the two types of growths has been found when varying the value of the power used to maintain the plasma discharge. Based on these results, the existence of different surface relaxation mechanisms is proposed, which quantitatively explains numerous experimental results under the same conceptual framework.

Impact of Arrhythmia in Hospital Mortality in Acute Ischemic Stroke Patients: A Retrospective Cohort Study in Northern Mexico.

BACKGROUND: Atrial fibrillation has been associated with higher morbidity and mortality rates in acute ischemic stroke patients (AIS). However, there is scarce information regarding the clinical outcomes and strokes' characteristics among AIS patients with other type of arrhythmias. OBJECTIVE: Our study aims to analyze the hospital mortality rate, stroke characteristics, and clinical and demographical data of patients with any post-stroke arrhythmia. METHODS: Retrospective cohort study of AIS patients with 24h-Holter monitoring during hospital admission recruited between 2015-2020, outcomes were measured using the modified Rankin scale. RESULTS: 597 patients (61.13±13.61 years; 352 men) were included. Arrhythmias were diagnosed in 33 (5.5%), with atrial fibrillation as the most common finding (82%). Age was related to a higher rate of arrhythmia (P = 0.014). A larger prevalence of cardioembolic strokes (69.7% vs 16.6%, P < 0.05) and AIS in the middle cerebral artery's vascular territory (78.8% vs 58.7%, P < 0.05) were found amongst patients with an arrhythmia. No significant association was found between NIHSS at admission with neither incidence of arrhythmia nor mortality. Within the arrhythmia group, three in-hospital deaths were reported: one AF, one ventricular arrhythmia and one second-degree atrioventricular block. In a logistic regression analysis, patients with any kind of arrhythmia had a higher mortality rate (9.1% vs 1.2%, P = 0.011; OR 6.766, 95% CI 1.552 - 29.500). CONCLUSION: Arrhythmia detection after an AIS was associated with increased in-hospital mortality. Risk factors related to arrhythmia detection were a higher mean age, cardioembolic strokes and AIS affecting the middle cerebral artery.

[Complication in replacement of unconventional tumor prosthesis]. / Complicación en recambio de prótesis tumoral no convencional.

Bone metastases from a primary cancer of any part of the body are the most common form of malignant bone tumor constituting approximately 70% of them. The proximal femur being the most common extra-vertebral location for its location; 10% of patients have some pathological fracture, which is a serious complication. Currently the objectives of the treatment of a pathological fracture are: resection with adequate oncological margins, that the patient survives the surgical intervention, maintain the functionality, that the placed implant has a longer life time than the patient. The use of non-conventional hip prostheses is an excellent treatment option fulfilling the 4 established objectives, therefore this case is presented in which a right bipolar hip hemiarthroplasty is performed with a non-conventional prosthesis where it was treated with a described complication and the surgery of resolution.

Testing a Paul trap through determining the evaporation rate of levitated single semi-volatile organic droplets.

Rigorous knowledge of the optical fingerprint of droplets is imperative for the understanding of complex aerosol processes. Here, a Paul trap is operated to store single semi-volatile organic droplets in air. The droplets are illuminated with a green laser and the elastic scattering is collected on a CMOS camera. The setup provides excellent performance in terms of confinement and stability, allowing us to detect size changes of the order of few nanometres. The stability also allows us to measure vapour pressures with remarkable reproducibility. This approach supplies a robust method for the optical interrogation in the sub-micron range.

Si Quiero Sanar, Debería Perdonar: Una Revisión Sobre el Perdón y la Salud / If I Want to Heal, I Should Forgive: A Review of Forgiveness and Health

Resumen La Organización Mundial de la Salud (OMS) entiende salud no solo como la ausencia de enfermedad, sino que también considera el bienestar personal. El perdón es un concepto relacionado con el bienestar y se conceptualiza generalmente como la reducción de los pensamientos, sentimientos y conductas negativas, así como el aumento de las positivas, en torno a la persona particular involucrada o a la situación de transgresión. A nivel biológico, se ha vinculado con marcadores de menor estrés fisiológico, con áreas cerebrales relacionadas con la teoría de la mente, la empatía, la regulación emocional, y con neurotransmisores como la oxitocina y monoaminas. Se asocia además a mejores resultados en salud mental y física, principalmente a nivel cardiovascular. Existen numerosas intervenciones en perdón que han mostrado efectividad, siendo los modelos teóricos con más evidencia el modelo de Enright y el modelo REACH. Dado los potenciales beneficios y escasos riesgos, el estudio y abordaje del perdón en la práctica clínica se convierte en una posibilidad que los clínicos deberían considerar para eventualmente disminuir el malestar y aumentar el bienestar de los pacientes.

The World Health Organization (WHO) understands health not only as the absence of disease, but also considers personal well-being. Forgiveness is a concept related to well-being and is generally conceptualized as the reduction of negative thoughts, feelings and behaviors, as well as the increase of positive ones, around the particular person involved or the situation of transgression. At the biological level, it has been linked to markers of lower physiological stress, with brain areas related to the theory of mind, empathy, emotional regulation, and neurotransmitters such as oxytocin and monoamines. It is also associated with better results in mental and physical health, mainly at the cardiovascular level. There are numerous interventions in forgiveness that have shown effectiveness, being the theoretical models with more evidence the Enright model and the REACH model. Given the potential benefits and few risks, the study and approach of forgiveness in clinical practice becomes a possibility that clinicians should consider to eventually reduce discomfort and increase the well-being of patients.

Full path single-shot imaging of femtosecond pulse collapse in air turbulence.

In a single shot, we measure the full propagation path, including the evolution to pulse collapse, of a high power femtosecond laser pulse propagating in air. Our technique enables examination of the effect of parameters that fluctuate on a shot-to-shot basis, such as pulse energy, pulse duration, and air turbulence-induced refractive index perturbations. We find that even in lab air over relatively short propagation distances, turbulence plays a significant role in determining the location of pulse collapse.

The sample was comprised of 444 youth high performance players (233 boys and 211 girls; M = 16,70; SD = 0,49). These players completed the Spanish version of the Beliefs about the Causes of Success in Sport Questionnaire and the Conceptions of the Nature of Athletic Ability Questionnaire-2. The results revealed that belief of incremental ability predict effort, while ability beliefs as an entity predict the capability and the deception as the causes of success in handball

Consecuencias psicosociales autodeterminadas mediante la promoción de responsabilidad en educación física / Self-Determinated Psychosocial Consequences through the Promotion of Responsibility in Physical Education

El objetivo de este estudio fue conocer las relaciones existentes entre la responsabilidad percibida por los estudiantes, los mediadores psicológicos, la motivación autodeterminada, deportividad, estilo de vida e intención de ser físicamente activo, proponiendo un modelo de predicción en consonancia con los postulados del modelo jerárquico de la motivación intrínseca y extrínseca. Participaron 128 estudiantes de Educación Física (68 chicos y 60 chicas) con edades comprendidas entre los 11 y los 15 años (M = 12,45; DT = 1,15). Se utilizó un diseño transversal. Se administraron los cuestionarios PSRQ, BPNES, CMEF, MSOS, IPAS y Test corto Krece Plus para medir las variables estudiadas. Los resultados mostraron que la responsabilidad percibida predijo positivamente la satisfacción de los mediadores psicológicos y estados de motivación autodeterminada. Como consecuencia, se explica una mayor importancia de la deportividad, de la intención de práctica futura y percepción del estilo de vida en los participantes

The aim of this study was to understand the relationships between the perceived responsibility by students, psychological mediators, self-determined motivation, sportsmanship, lifestyle and intention to be physically active, proposing a prediction model in line with the postulates of the hierarchical model of the intrinsic and extrinsic motivation. The participants were 128 students of Physical Education (68 boys and 60 girls) aged between 11 and 15 years (M = 12,45; SD = 1,15). A cross-sectional study was designed. The questionnaires PSRQ, BPNES, CMEF, MSOS, IPAS Krece Plus Short Test were used to measure the variables studied. The results showed that the perceived responsibility by students positively predicted the satisfaction of the psychological mediators and states of self-determined motivation. As a consequence of this, a greater importance of sportsmanship, intention of future practice and perception of lifestyle of the participating students is explained

Kinetic energy-induced growth regimes of nanocolumnar Ti thin films deposited by evaporation and magnetron sputtering.

We experimentally analyze different growth regimes of Ti thin films associated to the existence of kinetic energy-induced relaxation mechanisms in the material's network when operating at oblique geometries. For this purpose, we have deposited different films by evaporation and magnetron sputtering under similar geometrical arrangements and at low temperatures. With the help of a well-established growth model we have found three different growth regimes: (i) low energy deposition, exemplified by the evaporation technique, carried out by species with typical energies in the thermal range, where the morphology and density of the film can be explained by solely considering surface shadowing processes, (ii) magnetron sputtering under weak plasma conditions, where the film growth is mediated by surface shadowing mechanisms and kinetic-energy-induced relaxation processes, and (iii) magnetron sputtering under intense plasma conditions, where the film growth is highly influenced by the plasma, and whose morphology is defined by nanocolumns with similar tilt than evaporated films, but with much higher density. The existence of these three regimes explains the variety of morphologies of nanocolumnar Ti thin films grown at oblique angles under similar conditions in the literature.

Dermatitis atópica del adulto: un desafío diagnóstico y terapéutico / Adult atopic dermatitis: a challenge diagnosis and therapy

Adult atopic dermatitis is a chronically recurring inflammatory dermatosis which presents in various forms. Some of these forms develop mostly in adults such as head and neck dermatitis and chronic hand eczema. Even though the diagnosis is clinical it frequently requires further investigations to exclude differential diagnosis. Once confirmed, it is crucial to classify its severity and exclude other comorbidities. Treatment includes general measures such as the use of emollients and soap substitutes which are applicable in all cases regardless of its severity. Other therapeutic options include topical corticosteroids, topical calcineurin inhibitors, phototherapy and immunosuppressants. Their use will depend on the degree of severity and specific characteristics of each individual. Newer biologics have proven to be a safe and effective alternative, and seem to be a promising option in cases of adult atopic dermatitis refractory to conventional treatments. (AU)

Crystal structure and Hirshfeld surface analysis of 3-cyano-phenyl-boronic acid.

In the title compound, C7H6BNO2, the mean plane of the -B(OH)2 group is twisted by 21.28 (6)° relative to the cyano-phenyl ring mean plane. In the crystal, mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen bonds, forming chains propagating along the [101] direction. Offset π-π and B⋯π stacking inter-actions link the chains, forming a three-dimensional network. Hirshfeld surface analysis shows that van der Waals inter-actions constitute a further major contribution to the inter-molecular inter-actions, with H⋯H contacts accounting for 25.8% of the surface.

Supramolecular arrangement and photophysical properties of a dinuclear cyanophenylboronic acid ester.

Boronic esters are useful building blocks for crystal engineering and the generation of supramolecular architectures, including macrocycles, cages and polymers (one-, two- and three-dimensional), with potential utility in diverse fields such as separation, storage and luminescent materials. The novel dinuclear cyanophenylboronic ester described herein, namely 4,4'-(2,4,8,10-tetraoxa-3,9-diboraspiro[5.5]undecane-3,9-diyl)dibenzonitrile, C19H16B2N2O4, was prepared by condensation of 4-cyanophenylboronic acid and pentaerythritol and fully characterized by elemental analysis, IR and NMR (1H and 11B) spectroscopy, single-crystal X-ray diffraction analysis and TG-DSC (thermogravimetry-differential scanning calorimetry) studies. In addition, the photophysical properties were examined in solution and in the solid state by UV-Vis and fluorescence spectroscopies. Density functional theory (DFT) calculations with ethanol as solvent reproduced reasonably well the HOMO (highest occupied molecular orbital) and LUMO (lowest unoccupied molecular orbital) of the title compound. Hirshfeld surface and fingerprint plot analyses are presented to illustrate the supramolecular connectivity in the solid state.

The plasminogen receptor, Plg-RKT, is essential for mammary lobuloalveolar development and lactation.

Essentials Plg-RKT-/- female mice give birth, but no offspring of Plg-RKT-/- female mice survive to weaning. Causal mechanisms of potential lactational failure in Plg-RKT-/- mice are unknown. Plg-RKT regulates extracellular matrix remodeling, cell proliferation, apoptosis, fibrin surveillance. Plg-RKT is essential for lactogenesis and mammary lobuloalveolar development. SUMMARY: Background Lactational competence requires plasminogen, the zymogen of the serine protease, plasmin. Plg-RKT is a unique transmembrane plasminogen receptor that promotes plasminogen activation to plasmin on cell surfaces. Plg-RKT-/- mice are viable, but no offspring of Plg-RKT-/- female mice survive to weaning. Objectives We investigated potential lactational failure in Plg-RKT-/- mice and addressed causal mechanisms. Methods Fibrin accumulation, macrophage infiltration, processing of extracellular matrix components, effects of genetic deletion of fibrinogen, expression of fibrosis genes, and proliferation and apoptosis of epithelial cells were examined in lactating mammary glands of Plg-RKT-/- and Plg-RKT+/+ mice. Results Milk was not present in the stomachs of offspring of Plg-RKT-/- female mice and the pups were rescued by foster mothers. Although the mammary ductal tree developed normally in Plg-RKT-/- glands, lobuloalveolar development was blocked by a hypertrophic fibrotic stroma and infiltrating macrophages were present. A massive accumulation of fibrin was also present in Plg-RKT-/- alveoli and ducts. Although this accumulation was decreased when Plg-RKT-/- mice were made genetically heterozygous for fibrinogen, defects in lobuloalveolar development were not rescued by fibrinogen heterozygosity. Transcriptional profiling revealed that EGF was downregulated 12-fold in Plg-RKT-/- glands. Furthermore, proliferation of epithelial cells was not detectable. In addition, the pro-survival protein, Mcl-1, was markedly downregulated and apoptosis was observed in Plg-RKT-/- but not Plg-RKT+/+ glands. Conclusions Plg-RKT is essential for lactogenesis and functions to maintain the appropriate stromal extracellular matrix environment, regulate epithelial cell proliferation and apoptosis, and, by regulating fibrinolysis, preserve alveolar and ductal patency.

Structural control in porous/compact multilayer systems grown by magnetron sputtering.

In this work we analyze a phenomenon that takes place when growing magnetron sputtered porous/compact multilayer systems by alternating the oblique angle and the classical configuration geometries. We show that the compact layers develop numerous fissures rooted in the porous structures of the film below, in a phenomenon that amplifies when increasing the number of stacked layers. We demonstrate that these fissures emerge during growth due to the high roughness of the porous layers and the coarsening of a discontinuous interfacial region. To minimize this phenomenon, we have grown thin interlayers between porous and compact films under the impingement of energetic plasma ions, responsible for smoothing out the interfaces and inhibiting the formation of structural fissures. This method has been tested in practical situations for compact TiO2/porous SiO2 multilayer systems, although it can be extrapolated to other materials and conditions.

Perniosis idiopática: reporte de un caso y revisión de la literatura / Chilblains: report of a case and literature review

Pernio (chilblains) is an inflammatory condition classically characterized by localized erythema and swelling of acral sites upon exposure to cool and damp conditions. It is reported a case of a 59-year-old otherwise healthy woman with acute primary perniosis. She had a 3-day history of lesions on the toes brought on by cold, damp weather. On initial presentation, a biopsy sample was taken of a hallux lesion, and the patient was given a trial course of oral pentoxifylline, topical corticoid and nifedipine therapy. Follow-up at 2 weeks showed complete relief of symptoms and the biopsy results confirmed the diagnosis. Pentoxifylline therapy has been shown to be effective and should be considered the standard of care in the treatment of perniosis along with conservative environmental measures.The etiology and pathogenesis of perniosis are reviewed and discussed, as well as differential diagnoses and treatment options.
