Multichannel perimetric alterations in systemic lupus erythematosus treated with hydroxychloroquine

AbstractSystemic lupus erythematosus (SLE) is a multiorgan autoimmune disease of unknown etiology with many clinical manifestations.We report the first case of SLE in which visual alterations were evaluated with multichannel perimetry.Some achromatic and color vision alterations may be present in SLE, especially when treated with hydroxychloroquine. The sensitivity losses detected in the chromatic channels in the central zone of the visual field were consistent with the results of the FM 100 Hue color test. Likewise, the multichannel perimetry detected sensitivity losses in the parafoveal area for both chromatic channels, especially for the blue-yellow

A comparison between padding and bath exhaustion to apply microcapsules onto cotton

The final publication is available at Springer via http://dx.doi.org/10.1007/s10570-015-0600-8[EN] The use of Microcapsules has increased in the textile sector. They have been applied as a possible means of introducing new products to textiles, such as insect repellents, antibiotics, skin moisturizers, etc. Microencapsulation technology has improved the fragrance durability on fabrics. Historically, the durability of the fragrance was poor, especially once the fabric had been washed. Microcapsules have been used in textiles for many years, however their previous characterization, adhesion behaviour and permanence on the fabrics are not well known. Nowadays the majority of textile industries are not able to characterize commercial products, or to study the process of adhering the microcapsule to the fibre's surface nor their functionality. Thus, the characterization of microencapsulated fabrics with different active core and the knowledge of the various application processes becomes a major challenge in the field of microcapsules use. There are various industrial processes to apply microcapsules, but determining optimal amounts of products, temperature, conditions and other process variables are an important challenge for the textile sector in order to achieve the highest depositions and retention of microcapsules. This work is focused on determining and quantifying presence fragrance microcapsules when applied onto fabrics by padding and by bath exhaustion and determining which method is the most effective. Consequently, diverse analysis techniques such as microscopy (SEM), spectroscopy FTIR and XPS have been used. We concluded that proposed techniques seem to be useful to compare fabrics treated with microcapsules. Results demonstrate that padding application gives better yields than bath exhaustion.Bonet Aracil, MA.; Monllor Pérez, P.; Capablanca Francés, L.; Gisbert Paya, J.; Díaz-García, P.; Montava Seguí, IJ.

Visual function alterations in essential tremor: A case report

Our purpose is to report alterations in contrast sensitivity function (CSF) and in the magno, parvo and koniocellular visual pathways by means of a multichannel perimeter in case of an essential tremor (ET). A complete evaluation of the visual function was performed in a 69-year old patient, including the analysis of the chromatic discrimination by the Fansworth–Munsell 100 hue test, the measurement of the CSF by the CSV-1000E test, and the detection of potential alteration patterns in the magno, parvo and koniocellular visual pathways by means of a multichannel perimeter. Visual acuity and intraocular pressure (IOP) were within the ranges of normality in both eyes. No abnormalities were detected in the fundoscopic examination and in the optical coherence tomography (OCT) exam. The results of the color vision examination were also within the ranges of normality. A significant decrease in the achromatic CSFs for right eye (RE) and left eye (LE) was detected for all spatial frequencies. The statistical global values provided by the multichannel perimeter confirms that there were significant absolute sensitivity losses compared to the normal pattern in RE. In the LE, only a statistically significant decrease in sensitivity was detected for the blue-yellow (BY) channel. The pattern standard deviation (PSD) values obtained in our patient indicated that there were significant localized losses compared to the normality pattern in the achromatic channel of the RE and in the red-green (RG) channel of the LE. Some color vision alterations may be present in ET that cannot be detected with conventional color vision tests, such as the FM 100 Hue

Pig manure treatment with housefly (Musca domestica) rearing – an environmental life cycle assessment

The largest portion of a product’s environmental impacts and costs of manufacturing and use results from decisions taken in the conceptual design phase long before its market entry. To foster sustainable production patterns, applying life cycle assessment in the early product development stage is gaining importance. Following recent scientific studies on using dipteran fly species for waste management, this paper presents an assessment of two insect-based manure treatment systems. Considering the necessity of manure treatment in regions with concentrated animal operations, reducing excess manure volumes with the means of insects presents a potentially convenient method to combine waste reduction and nutrient recovery. An analytical comparison of rearing houseflies on fresh and pre-treated pig manure is reported with reference to agricultural land occupation, water and fossil depletion potential. Based on ex-ante modelled industrial scale rearing systems, the driving factors of performance and environmentally sensitive aspects of the rearing process have been assessed. Expressed per kg manure dry matter reduction, the estimated agricultural land occupation varied between 1.4 and 2.7 m2yr, fossil depletion potential ranged from 1.9 to 3.4 kgoil eq and the obtained water depletion potential was calculated from 36.4 to 65.6 m3. System improvement potential was identified for heating related energy usage and water consumption. The geographical context and the utility of the co-products, i.e. residue substrates and insect products, were determined as influential variables to the application potential of this novel manure treatment concept. The results of this study, applied at the earliest stages of the design of the process, assist evaluation of the feasibility of such a system and provide guidance for future research and development activities.The research leading to these results has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no. 312084 (PROteINSECT)

Binder effectiveness of microcapsules applied onto cotton fabrics during laundry

[EN] Microcapsules can be added to fabric in industrial processes; however, they have not been widely spread among industrial companies. In this study, we suggest the possibility of reloading microcapsules onto a fabric while clothes are washed. The effectiveness of different resins when microcapsules are applied in washing machine during domestic laundry process has been studied. Microcapsules containing lavender fragrance and melamine formaldehyde shell were adhered to the fabric by means of one acrylic acid as a resin (RES) or some cross-linking agents, such as butanetetracarboxylic acid or succinic acid (SUC). In order to evaluate their behaviour, some laundering or ironing tests were conducted according to international standards (ISO). Every sample from the laboratory was studied with scanning electron microscopy and with a particle size counter. As a result, we could observe which was the most suitable auxiliary used to bind microcapsules to fabric, and conclude that the conditions in which we obtained the application with SUC as binder and cured at 150 °C for 2 min show the optimal results. It was demonstrated that domestic laundry is a suitable process to incorporate microcapsules to garments.Authors gratefully acknowledge the financial support received by this research project from the Spanish government in the programme 'Plan Nacional 2008-2011' reference Mat 2009-14210-C02-01.Bonet Aracil, MA.; Bou Belda, E.; Monllor Pérez, P.; Gisbert; Jaime (2016).

Holographic Data Storage Using Parallel-Aligned Liquid Crystal on Silicon Displays

The parallel-aligned liquid crystal on silicon (PA-LCoS) microdisplay has become a widely used device for the photonics community. It is a very versatile tool that can perform several tasks which transforms it into a key element in many different photonics applications. Since our group is interested in holography, in this chapter, we want to use these displays as the data entry point for a holographic data storage system (HDSS). Due to the novelty of this kind of device, we have done an intense work characterizing it. These efforts are reflected in this chapter where the reader will find two different characterization methods that will enable to predict the performance of the device in a specific application. Additionally, we present how a phase-only device can be used as a data pager using different modulation schemes and combined with a photopolymer as the holographic recording material

POSITION PAPER OF THE CATALAN SOCIETY OF GASTROENTEROLOGY ABOUT HEPATIC ELASTOGRAPHY 2022

After almost 20 years using transient elastography (TE) for the non-invasive diagnosis of liver fibrosis, its use has been extended to population screening, evaluation of steatosis and complications of cirrhosis. For this reason, the "Catalan Society of Digestology" commissioned a group of experts to update the first Document carried out in 2011.The working group (8 doctors and 4 nurses) prepared a panel of questions based on the online survey "Hepatic Elastography in Catalonia 2022" following the PICO structure and the Delphi method.The answers are presented with the level of evidence, the degree of recommendation and the final consensus after being evaluated by 2 external reviewers.TE uses the simplest and most reliable elastographic method to quantify liver fibrosis, assess steatosis, and determine the risk of complications in patients with cirrhosis.Copyright © 2022 Elsevier España, S.L.U.

Going it alone won’t work! The relational imperative for social innovation in social enterprises

Shifts in the philosophy of the “state” and a growing emphasis on the “Big Society” have placed an increasing onus on a newly emerging organizational form, social enterprises, to deliver innovative solutions to ease societal issues. However, the question of how social enterprises manage the process of social innovation remains largely unexplored. Based on insights from both in-depth interviews and a quantitative empirical study of social enterprises, this research examines the role of stakeholder relationships in supporting the process of social innovation within social enterprises. We find that social enterprises are adept at working with their stakeholders in the ideation stage of social innovation. In contrast, they often fail to harness knowledge and expertise from their partners during the social innovation implementation phase. Consequently, we propose a social innovation–stakeholder relationship matrix that provides social enterprises in particular with insight for developing stakeholder relationships to achieve their social innovation missions
