Summary Background Oxidative stress is present in airway diseases such as severe asthma or Chronic Obstructive Pulmonary Disease and contributes to the low response glucocorticoids through down‐regulation of histone deacetylase (HDAC) activity. Objective To study effects phosphodiesterase (PDE)‐3 4 inhibitors their combination vs. a model lipopolysaccharide (LPS)‐induced cytokine release alveolar macrophages under oxidative conditions. Methods Differentiated U937 human were stimulated with H...

This paper presents the MnemoCity task, which is a 3D application that introduces user into totally virtual environment to evaluate spatial short-term memory. A study has been carried out validate task for assessment of memory in children, by comparing children’s performance developed with current approaches. total 160 children participated study. The incorporates two types interaction: one based on standard interaction and another natural involving physical movement user. There were no...

This paper presents an Augmented Reality (AR) game for learning words. Thirty-two children played the AR and equivalent real game. We have compared results of two games. The indicate that did not found significant differences between games except one question, but 81% liked most

Up to now, vibrations have mostly been sensed by measuring displacement, velocity, and acceleration. The most common types of vibration sensors are piezoelectric, capacitive, null-balance, strain gage, optoelectronic, resonance beam, piezoresistive. We present a low-cost low-power detector based on the measurement magnetic field variations induced in recent SS501 giant magnetoresistance (GMR) sensor, for which has never applied. Vibrations small ferromagnetic pieces disturb Earth's field....

Modeling and rendering of plants trees requires generating processing large numbers polygons. Geometry simplification methods may be used to reduce the polygon count obtain a multiresolution representation. However, those fail preserve visual structure tree. We propose different approach: procedural multiresolution. build models that reflect tree's at resolution levels. The are based on parametric L-systems. Our method takes chain representing tree generates new with embedded information....

In this paper, we present the Virtual Maze Task that assesses spatial short-term memory in adults involving physical movement and immersion.For movement, used a real bicycle.For immersion, VR HMD.We compared exposure to task using two different interaction types (physical active vs. inactive conditions).The performance sensations of participants were both conditions.We also on virtual with classical neuropsychological tests.A total 89 participated our study.The participants' ability learn...

For years, stereoscopy has been related to photogrammetry in topography. However, these methods are not efficient for virtual globes because the effect is only visible from one view point and this restricts interactivity. By using synthetic image techniques order generate stereo-paired images, we can produce effects any point. In paper, present a comparative study of stereoscopic supported by test carried out among 51 participants. Three devices were used: anaglyphs, an autostereoscopic...

In this study we report on the helminth fauna of invasive American red-eared slider Trachemys scripta in five localities from eastern Spain where species co-occurs with two native, endangered freshwater turtles, i.e. Emys orbicularis and Mauremys leprosa. total, 46 individuals T. were analysed for parasites. Adult three found: monogenean Neopolystoma orbiculare, digenean Telorchis solivagus nematode Serpinema microcephalus. S. microcephalus are trophically transmitted parasites native...

In this paper, the first virtual reality (VR) photography application that incorporates elements on panoramic images to assess short-term spatial memory is presented. It also allows interaction with these elements. A study was conducted (N = 50) compare participants' performance outcomes and subjective experience when using a VR without photography. The results show both applications are effective in assessing memory. include: 1) for recall since, after application, participants were able...

We present a client/server system that is able to display 3D scenes on handheld devices. This kind of devices have important restrictions memory and computing power. Therefore, we need limit the amount geometry sent by server each client. extract visible for client send it. The clients render using OpenGL ES [10] API. Our extraction algorithm employs multiresolution view-dependent simplification. results our running software implementation runs Pock-etPC 2003.

We studied the helminth communities in 6 sympatric species of Ardeidae (Ixobrychus minutus (Linnaeus, 1766), Nycticorax nycticorax 1758), Bubulcus ibis Egretta garzetta Ardea cinerea and purpurea 1766)) from "La Albufera de Valencia," Spain. The survey revealed 13 parasites: 5 digeneans, 2 cestodes, nematodes. component examined are depauperate conform to pattern typically found isolationist communities, probably because their high trophic dependence on a few prey species. Evenness was...

Abstract The phylogenetic relationships among the wall lizards of Podarcis hispanicus complex that inhabit south‐east (SE) Iberian Peninsula and other lineages remain unclear. In this study, four mitochondrial two nuclear markers were used to study genetic within complex. analyses based on mtDNA gene trees constructed with ML BI, a species tree using *BEAST support three divergent clades in region: Valencia, Galera Albacete/Murcia lineages. These also corroborated delimitation bPTP, mPTP,...

We introduce a new representation for modeling and rendering plants trees. The is multiresolution can be automatically generated rendered in an efficient way. For the trunk branches we procedurally build structure that preserves visual appearance of tree, when at different levels detail. leaves hierarchy images by pre-processing botanical tree structure. Unlike other representations, quality our does not depend on viewing position direction. Our models applied to any computer graphics area...

This article determines the precision of most relevant GPS models used in marathon races. It uses public data participants leading marathons. We have retrieved 73 865 records from 85 models. There are differences obtained by road compared with designed for trail races and mobile phones. The also depends on finish time: longer race takes, higher error. No evidence among studied brands appear. results can be helpful manufacturers to get field information about behavior devices real conditions....

A Mixed Reality (MR) application using an optical see-through headset was developed to assess short-term spatial memory. study with 29 participants conducted. Data from this were compared two previous studies mobile Augmented (AR) and Virtual (VR) headsets. When comparing the three technologies (MR, AR, VR) for performance variables, there no statistically significant differences either total number of correctly placed objects or attempts. However, MR required more time than AR VR...

Abstract Paracrobeles psammophilus sp. nov. (Nematoda: Cephalobidae) is described from soil of the Dehesa de El Saler (province Valencia, Spain). This second record a species genus Heyns, 1968. The new characterized by rounded cheilorhabdions and large spicules gubernaculum males.
