    RESUMEN Problema: Uno de los problemas más significativos de productores de tapices de la ciudad de Ayacucho, no es su tamaño, sino su aislamiento que repercute en: a) altos costos operativos. b) no lograr economía de escala. c) no acceder  a nuevos mercados, d) desconocer  nuevas formas de hacer negocio, e) falta de modernización empresarial y reconversión industrial, baja productividad y competitividad, falta de investigación, desarrollo e innovación, f) mínima y deficiente oferta exportable. Objetivo: Fue determinar el modelo de asociatividad que impulse la exportación directa de los tapices de la ciudad de Ayacucho. Tipo de investigación: Aplicada. Metodología: Inductivo y deductivo. Diseño descriptivo-correlacional y no experimental. Población: 150 empresas formalmente constituidas en el año 2014; para recolectar datos utilizamos cuestionario auto administrado; en la tabulación utilizamos la estadística inferencial. Resultados. Como resultado de análisis de datos concluimos que la falta de asociatividad de los productores limita la exportación directa los tapices de la ciudad de Ayacucho.Palabra clave: Asociatividad para la exportación.ABSTRAC Problem: One of the producers' most significant problems of tapestries of Ayacucho's city, is not his size, but his isolation that reverberates in: a) high operative costs. b) not to achieve economy on a large scale. c) Not to accede to new markets, d) not to know new ways of doing business, e) lack of managerial modernization and industrial restructuring, low productivity and competitiveness, lack of investigation, development and innovation, f) minimal and deficient exportable offer.

    Circuit dissection of the role of somatostatin in itch and pain

    Get PDF
    Stimuli that elicit itch are detected by sensory neurons that innervate the skin. This information is processed by the spinal cord; however, the way in which this occurs is still poorly understood. Here we investigated the neuronal pathways for itch neurotransmission, particularly the contribution of the neuropeptide somatostatin. We find that in the periphery, somatostatin is exclusively expressed in Nppb+ neurons, and we demonstrate that Nppb+somatostatin+ cells function as pruriceptors. Employing chemogenetics, pharmacology and cell-specific ablation methods, we demonstrate that somatostatin potentiates itch by inhibiting inhibitory dynorphin neurons, which results in disinhibition of GRPR+ neurons. Furthermore, elimination of somatostatin from primary afferents and/or from spinal interneurons demonstrates differential involvement of the peptide released from these sources in itch and pain. Our results define the neural circuit underlying somatostatin-induced itch and characterize a contrasting antinociceptive role for the peptide

    Human hippocampal neurogenesis drops sharply in children to undetectable levels in adults.

    New neurons continue to be generated in the subgranular zone of the dentate gyrus of the adult mammalian hippocampus. This process has been linked to learning and memory, stress and exercise, and is thought to be altered in neurological disease. In humans, some studies have suggested that hundreds of new neurons are added to the adult dentate gyrus every day, whereas other studies find many fewer putative new neurons. Despite these discrepancies, it is generally believed that the adult human hippocampus continues to generate new neurons. Here we show that a defined population of progenitor cells does not coalesce in the subgranular zone during human fetal or postnatal development. We also find that the number of proliferating progenitors and young neurons in the dentate gyrus declines sharply during the first year of life and only a few isolated young neurons are observed by 7 and 13 years of age. In adult patients with epilepsy and healthy adults (18-77 years; n = 17 post-mortem samples from controls; n = 12 surgical resection samples from patients with epilepsy), young neurons were not detected in the dentate gyrus. In the monkey (Macaca mulatta) hippocampus, proliferation of neurons in the subgranular zone was found in early postnatal life, but this diminished during juvenile development as neurogenesis decreased. We conclude that recruitment of young neurons to the primate hippocampus decreases rapidly during the first years of life, and that neurogenesis in the dentate gyrus does not continue, or is extremely rare, in adult humans. The early decline in hippocampal neurogenesis raises questions about how the function of the dentate gyrus differs between humans and other species in which adult hippocampal neurogenesis is preserved

    Evaluation of the influence of kyphosis and scoliosis on intervertebral disc extrusion in French bulldogs

    Get PDF
    Although thoracic vertebral malformations with kyphosis and scoliosis are often considered incidental findings on diagnostic imaging studies of screw-tailed brachycephalic breeds, they have been suggested to interfere with spinal biomechanics and intervertebral disc degeneration. It is however unknown if an abnormal spinal curvature also predisposes dogs to develop clinically relevant intervertebral disc herniations. The aim of this study was to evaluate if the occurrence of thoracic vertebral malformations, kyphosis or scoliosis would be associated with a higher prevalence of cervical or thoracolumbar intervertebral disc extrusion in French bulldogs

    Paecilomyces lilacinus causing debilitating sinusitis in an immunocompetent patient: a case report

    <p>Abstract</p> <p>Introduction</p> <p>Since the discovery of the first documented case of <it>Paecilomyces </it>in 1963, only five cases of <it>Paecilomyces </it>sinusitis have been described to date and all of them have predisposing factors such as immunocompromised status or prior nasal surgery. We present the first case of <it>Paecilomyces lilacinus </it>sinusitis in a fit young woman with no identified predisposing factors. To the best of our knowledge, this is the first known case in the UK and in Europe.</p> <p>Case presentation</p> <p>A 20-year-old Iraqi woman who has lived in the UK for the past five years presented with rhinorrhea, hyposmia, and nasal obstruction. She was previously fit and well and had no significant medical history. Imaging revealed a fungal infection that was eventually revealed on cytological examination to be <it>P. lilacinus</it>.</p> <p>Conclusions</p> <p><it>P. lilacinus </it>is both a difficult and important organism to identify because it has intrinsic anti-fungal resistance. In our case, the infection was severe and recurrent, and the organism demonstrated resistance to common oral anti-fungal agents. There was a delay in its diagnosis, owing to its similarity in appearance to <it>Penicillium </it>and a difficulty in distinguishing between the two without specialized knowledge of fungal taxonomy. In the field of otolaryngology, <it>Paecilomyces </it>is relatively unknown. Our intention is to raise awareness of this organism as well as to describe the challenges in its management.</p

    LRRK2 is a negative regulator of <em>Mycobacterium tuberculosis</em> phagosome maturation in macrophages

    \ua9 2018 EMBO. Mutations in the leucine-rich repeat kinase 2 (LRRK2) are associated with Parkinson\u27s disease, chronic inflammation and mycobacterial infections. Although there is evidence supporting the idea that LRRK2 has an immune function, the cellular function of this kinase is still largely unknown. By using genetic, pharmacological and proteomics approaches, we show that LRRK2 kinase activity negatively regulates phagosome maturation via the recruitment of the Class III phosphatidylinositol-3 kinase complex and Rubicon to the phagosome in macrophages. Moreover, inhibition of LRRK2 kinase activity in mouse and human macrophages enhanced Mycobacterium tuberculosis phagosome maturation and mycobacterial control independently of autophagy. In vivo, LRRK2 deficiency in mice resulted in a significant decrease in M. tuberculosis burdens early during the infection. Collectively, our findings provide a molecular mechanism explaining genetic evidence linking LRRK2 to mycobacterial diseases and establish an LRRK2-dependent cellular pathway that controls M. tuberculosis replication by regulating phagosome maturation
