Saprolegnia species affecting the salmonid aquaculture in Chile and their associations with fish developmental stage
(Facultad de Ciencias, 2014)The rapid increase in the aquaculture production of salmonids has been followed by a rise in several diseases. In particular, saprolegniosis can account for at east 10% of the annual economic loss in salmonids. In this ... -
Schwann cell and axon: An interlaced unit—From action potential to phenotype expression
(Facultad de Ciencias, 2016)Here we propose a model of a peripheral axon with a great deal of autonomy from its cell body-the autonomous axon-but with a substantial dependence on its ensheathing Schwann cell (SC), the axon-SC unit. We review evidence ... -
Schwann cell reprogramming into repair cells increases miRNA-21 expression in exosomes promoting axonal growth
(Company of Biologists Ltd, 2020-06)Functional recovery after peripheral nerve damage is dependent on the reprogramming of differentiated Schwann cells (dSCs) into repair Schwann cells (rSCs), which promotes axonal regeneration and tissue homeostasis. ... -
Seasonality Analysis of Sentinel-1 and ALOS-2/PALSAR-2 Backscattered Power over Salar de Aguas Calientes Sur, Chile
(MDPI Multidisciplinary Digital Publishing Institute, 2020-03)Seasonal changes control the development of salt crust over the Salar de Aguas Calientes Sur located in Andes Highlands, Chile. Precipitations throughout the Altiplanic winter (December to March) and austral winter (June ... -
Secuenciación del gen CFTR en un grupo de pacientes chilenos con fibrosis quística
(Facultad de Ciencias, 2014)Introducción: La fibrosis quística (FQ) es un trastorno autosómico recesivo causado por mutaciones en el gen CFTR, en el cual se han identificado más de 1.900 mutaciones diferentes. En Chile, el panel diagnóstico con las ... -
Security evaluation in wireless networks
(Springer, 2018)In the last years, the breathtaking development of technology has had as principal focus the growth of mobile and wireless devices. The last is more predominant in the market due to the apogee of the wireless networks. ... -
La seducción en El nido de la serpiente. Memorias del hijo del heladero de Pedro Juan Gutiérrez
(Estudios Interdisciplinarios, 2018)El nido de la serpiente. Memorias del hijo del heladero del escritor cubano Pedro Juan Gutiérrez desata la conjura del mal y del principio de incertidumbre, logrando un efec to de ilusión y de reversibilidad que atenta ... -
Senescent Schwann cells induced by aging and chronic denervation impair axonal regeneration following peripheral nerve injury
(Wiley-Blackwell, 2023-12-07)Following peripheral nerve injury, successful axonal growth and functional recovery require Schwann cell (SC) reprogramming into a reparative phenotype, a process dependent upon c-Jun transcription factor activation. ... -
Senior Citizens’ Training Experience in Secure Electronic Payment Methods
(Proceedings of Seventh International Congress on Information and Communication Technology, 2022-07-27)Virtual training is a mechanism that enables contemporary society to be literate, allowing up-to-date information on the technological environment, improving cognitive abilities as well as soft skills required in the ... -
Sequential epidemic-like spread between agglomerates of self-propelled agents in one dimension
(American Physical Society, 2023-10-02)Motile organisms can form stable agglomerates such as cities or colonies. In the outbreak of a highly contagious disease, the control of large-scale epidemic spread depends on factors like the number and size of agglomerates, ... -
SGSI support throught malware's classification using a pattern analysis
(IEEE, 2016)Nowadays, there are significant amounts of malware codes that are created every day. However, the majority of these samples (malware) are variations of other malware that have been already identified. Therefore, most of ... -
Simulated mechanical properties of finite-size graphene nanoribbons
(IOP Publishing Ltd., 2021-01)There are many simulation studies of mechanical properties of graphene nanoribbons (GNR), but there is a lack of agreement regarding elastic and plastic behavior. In this paper we aim to analyze mechanical properties of ... -
Simulated nanoindentation into single-phase fcc FexNi1-x alloys predicts maximum hardness for equiatomic stoichiometry
(NATURE PORTFOLIO, 2023-06-16)We investigate by molecular dynamics simulation the mechanical behavior of concentrated alloys under nanoindentation for the special example of single-phase fcc FexNi1-x alloys. The indentation hardness is maximum for the ... -
Simultaneous optical flow and occlusion estimation for images with large displacements
(IEEE, 2017)In this paper we present a method for estimating occlusion of pixels in image sequences. The estimation of the occlusion layer is based on optical flow. In our proposal the optical flow is computed in an exhaustive way by ... -
Sister Mary Joseph’s nodule: From the history to the images. A case-based literature review [Nódulo de la hermana María José: De la historia a las imágenes. Una revisión de la literatura basada en casos]
(Sociedad Argentina de Gastroenterologia, 2018)Sister Mary Joseph’s nodule refers to a palpable nodule bulging into the umbilicus as result of a malignant cancer in the abdomen or pelvis. It is associated with multiple peritoneal metastases and usually indicates an ... -
