Aging Alters Olfactory Bulb Network Oscillations and Connectivity: Relevance for Aging-Related Neurodegeneration Studies.

The aging process eventually cause a breakdown in critical synaptic plasticity and connectivity leading to deficits in memory function. The olfactory bulb (OB) and the hippocampus, both regions of the brain considered critical for the processing of odors and spatial memory, are commonly affected by aging. Using an aged wild-type C57B/6 mouse model, we sought to define the effects of aging on hippocampal plasticity and the integrity of cortical circuits. Specifically, we measured the long-term potentiation of high-frequency stimulation (HFS-LTP) at the Shaffer-Collateral CA1 pyramidal synapses. Next, local field potential (LFP) spectra, phase-amplitude theta-gamma coupling (PAC), and connectivity through coherence were assessed in the olfactory bulb, frontal and entorhinal cortices, CA1, and amygdala circuits. The OB of aged mice showed a significant increase in the number of histone H2AX-positive neurons, a marker of DNA damage. While the input-output relationship measure of basal synaptic activity was found not to differ between young and aged mice, a pronounced decline in the slope of field excitatory postsynaptic potential (fEPSP) and the population spike amplitude (PSA) were found in aged mice. Furthermore, aging was accompanied by deficits in gamma network oscillations, a shift to slow oscillations, reduced coherence and theta-gamma PAC in the OB circuit. Thus, while the basal synaptic activity was unaltered in older mice, impairment in hippocampal synaptic transmission was observed only in response to HFS. However, age-dependent alterations in neural network appeared spontaneously in the OB circuit, suggesting the neurophysiological basis of synaptic deficits underlying olfactory processing. Taken together, the results highlight the sensitivity and therefore potential use of LFP quantitative network oscillations and connectivity at the OB level as objective electrophysiological markers that will help reveal specific dysfunctional circuits in aging-related neurodegeneration studies.

Graphene sculpturene nanopores for DNA nucleobase sensing.

To demonstrate the potential of nanopores in bilayer graphene for DNA sequencing, we computed the current-voltage characteristics of a bilayer graphene junction containing a nanopore and found that they change significantly when nucleobases are transported through the pore. To demonstrate the sensitivity and selectivity of example devices, we computed the probability distribution PX(ß) of the quantity ß representing the change in the logarithmic current through the pore due to the presence of a nucleobase X (X = adenine, thymine, guanine, or cytosine). We quantified the selectivity of the bilayer-graphene nanopores by showing that PX(ß) exhibits distinct peaks for each base X. To demonstrate that such discriminating sensing is a general feature of bilayer nanopores, the well-separated positions of these peaks were shown to be present for different pores, with alternative examples of electrical contacts.

El cuidado de enfermería: una visión integradora en tiempos de crisis / Nursing care: an integrating vision in times of crisis

Existen diversas organizaciones y movimientos humanitarios a nivel mundial que tratan de luchar contra las expresiones de deshumanización, sin embargo, continúa la presencia de situaciones que son causas de dolor en el mundo, por lo que debemos constituir una sociedad para que el mundo sea civilizado, vivir por la calidad de vida y no por acumular cifras estadísticas. El cuidado es una característica común de todos los seres vivos. Por consiguiente, el cuidado humano se reconoce como un concepto universal, inherente a la humanidad. Heidegger, el filósofo por excelencia del cuidado, reconoce que éste es "una constitución ontológica, siempre subyacente a todo lo que el ser humano emprende, proyecta y hace". Enfermería como profesión de naturaleza social intenta que su personal, bajo una óptica humanista, ayude a la persona solicitante del cuidado a reforzar potencialidades y/o minimizar desequilibrios en su estado de salud, por ello reconoce al ser humano como un ser complejo, misterioso, estructurado por diversas dimensiones que van de lo orgánico a lo espiritual, de lo tangible a lo intangible; con inclusión del aspecto social e histórico, que lo define como un ser de interrelaciones permanentes consigo mismo y el mundo. Bajo esta perspectiva, en enfermería, se procura reconocer que la persona cuidada es una entidad única, poseedora de atributos: conciencia, intelecto, dignidad, emociones, sentimientos y saberes, por lo tanto, el cuidado en enfermería asume una dimensión humanista y comprensiva del ser, cuya subjetividad está estructurada por sus vivencias y significados, sentimientos, emociones, intuiciones, razonamientos (AU)

Nowadays, there exist several organizations of humanitarian movements all over the world which try to fight against the dehumanization expressions; however there still exists the presence of situations which are the reasons of pain in the world. That is why we must construct a better and civilized world in which people worries about the quality of life instead of accumulating statistical numbers .Care is a common feature of all human beings. Therefore, human care is recognized as a universal concept, inherent in humanity. Heidegger, the philosopher for excellence of care, recognizes that this is "an ontological constitution that is always underlying to all what the human beings begin, project and make." Nursing as a profession of social nature tries that its staff , under an humanistic perspective , helps the person interested in care to reinforce his /her abilities and /or to minimize imbalances in her /his state of health .That is why it recognizes the human beings as a complex , mysterious and structured in several dimensions being that range from the organic to the spiritual, from the tangible to the intangible , including the social and historical aspect , which defines it as a being of permanent relationships with himself and the world. Under this point of view, nursing tries to recognize that the cared person is a unique entity which has attributes such as: awareness, intellect, dignity, emotions, feelings and knowledge. Therefore, the nursing care assumes a comprehensive and humanistic dimension of the human being whose subjectivity is structured by his experiences ,meanings , feelings , emotions , intuitions ,and reasoning (AU)

Advanced simulation of conductance histograms validated through channel-sensitive experiments on indium nanojunctions.

We demonstrate a self-contained methodology for predicting conductance histograms of atomic and molecular junctions. Fast classical molecular-dynamics simulations are combined with accurate density functional theory calculations predicting both quantum transport properties and molecular-dynamics force field parameters. The methodology is confronted with experiments on atomic-sized indium nanojunctions. Beside conductance histograms the distribution of individual channel transmission eigenvalues is also determined by fitting the superconducting subgap features in the I-V curves. The remarkable agreement in the evolution of the channel transmissions demonstrates that the simulated ruptures are able to reproduce a realistic statistical ensemble of contact configurations, whereas simulations on selected ideal geometries show strong deviations from the experimental observations.

Evolutionary Local Search of Fuzzy Rules through a novel Neuro-Fuzzy encoding method.

This paper proposes a new approach for constructing fuzzy knowledge bases using evolutionary methods. We have designed a genetic algorithm that automatically builds neuro-fuzzy architectures based on a new indirect encoding method. The neuro-fuzzy architecture represents the fuzzy knowledge base that solves a given problem; the search for this architecture takes advantage of a local search procedure that improves the chromosomes at each generation. Experiments conducted both on artificially generated and real world problems confirm the effectiveness of the proposed approach.

Analysis of the characteristics of competitive badminton.

OBJECTIVE: To describe the characteristics of badminton in order to determine the energy requirements, temporal structure, and movements in the game that indicate performance level. To use the findings to plan training with greater precision. METHODS: Eleven badminton players (mean (SD) age 21.8 (3.26) years) with international experience from four different countries (France, Italy, Spain, and Portugal) were studied. Two of the Spanish players were monitored in several matches, giving a total of 14 samples, all during the 1999 Spanish International Tournament. Blood lactate concentration was measured with a reflective photometer. Maximum and average heart rates were recorded with a heart rate monitor. Temporal structure and actions during the matches were determined from video recordings. All variables were measured during and after the game and later analysed using a descriptive study. RESULTS: The results confirmed the high demands of the sport, with a maximum heart rate of 190.5 beats/min and an average of 173.5 beats/min during matches over 28 minutes long and performance intervals of 6.4 seconds and rest time of 12.9 seconds between exchanges. CONCLUSIONS: The results suggest that badminton is characterised by repetitive efforts of alactic nature and great intensity which are continuously performed throughout the match. An awareness of these characteristics, together with data on the correlations between certain actions such as unforced errors and winning shots and the final result of the match, will aid in more appropriate planning and monitoring of specific training.
