When biology became engineering : adopting standards for living systems
For decades, molecular biologists have been removing or inserting genes into all kinds of organisms with biotechnological intent or simply to generate fundamental knowledge. Synthetic biology (SynBio) goes one step further by incorporating conceptual frameworks from computing, electronics, and industrial design. This change makes it possible to conceive the creation of complex biological objects that were previously considered too difficult to assemble. To do this, the stages of any industrial production process must be adopted: design, construction of the components, assembly, and final manufacture. This objective requires standardisation of the physical and functional formats of the components involved, DNA assembly methods, activity measurements, and descriptive languages
La investigación biomédica
Not availableEn este artículo se repasan brevemente algunas de las grandes transformaciones que ha sufrido la Biología Experimental en la última década y su repercusión en la Investigación Biomédica en el CSIC. Se diferencian las nuevas tecnologías (cuyo penúltimo avance es la robotización de operaciones altamente especializadas), de los nuevos esquemas organizativos dirigidos a una alta productividad científica y material. Finalmente se ofrece una visión de las fortalezas y debilidades del CSIC para afrontar las demandas de la investigación biológica en el nuevo siglo y se discuten algunas posibles líneas de actuación. En la opinión del autor, no hay mayor reto en estos momentos para el CSIC que el generar nuevas estructuras organizativas lo suficientemente flexibles como para responder en tiempo real a los cambios acelerados que experimenta la investigación biomédica a nivel mundial

Environmental distribution of Porcine Circovirus Type 2 (PCV2) in swine herds with natural infection
Porcine circovirus type 2 (PCV2) is the aetiological agent of PCV2-Systemic Disease (PCV2-SD) and PCV2-Subclinical Infection (PCV2-SI). PCV2 is highly resistant to environmental conditions, being able to remain in the farm environment and thus represent a risk for infection maintenance. The aim of this study was to identify, under field conditions, the possible critical points in the environment of non-vaccinated farrow-to-weaning swine farms where PCV2 could accumulate and persist. For that, environmental samples from five swine farms with PCV2-SD or PCV2-SI were taken and analysed by qPCR, including different farm areas, farm personnel and management implements. PCV2 DNA was detected in the environment of all farms (42.9% of positive samples). Overall, the PCV2-SD herd seemed to present more positive samples and higher viral loads than the PCV2-SI herds. At individual farm level, weaning areas appeared to be the most contaminated facilities. In addition, PCV2 was found at high levels in most samples from farm workers, especially work boots, suggesting that they may play a role in within-farm transmission. In addition, PCV2 was detected in areas without animals the like warehouses, offices and farm perimeter. Therefore, this study is helpful to improve measures to reduce within-farm PCV2 dissemination.This work has been funded by the European PCV2-Award 2016 sponsored by Boehringer Ingelheim Animal Health, GermanyS
Orchestrating ubiquitous learning situations about Cultural Heritage with Casual Learn mobile application
Producción CientíficaCultural Heritage learners can highly benefit from ubiquitous learning approaches that connect in-classroom activities with active on-site learning opportunities. However, teachers face the problem that the current landscape of technological support for learning Cultural Heritage mostly consists of mobile applications for informal contexts, completely decoupled from curricular activities. This paper presents the results of an exploratory-sequential mixed-methods study that focuses on the feasibility, for non-technical expert teachers, of repurposing an existing mobile application in formal Cultural Heritage ubiquitous learning situations. Such feasibility is explored from the perspective of the orchestration metaphor. More specifically, we used the “5+3 aspects orchestration framework” to understand the orchestration challenges of four ubiquitous learning situations about Cultural Heritage carried out in two secondary schools. These situations involved five teachers and 139 students who used a mobile application called Casual Learn for several weeks. The results of the study suggest that, after a brief training, teachers can design, enact, and orchestrate ubiquitous learning situations that involve both in-classroom and out-classroom activities. The teachers were able to transfer to the students most of the orchestration load of out-classroom activities. The results also showed that the flow of learning artifacts and information between in- and out-classroom activities is a critical issue that needs to be addressed by developers of ubiquitous learning technological solutions.Junta de Castilla y Leon - Fondo Europeo de Desarrollo Regional (project VA257P18)Agencia Estatal de Investigación - Fondo Europeo de Desarrollo Regional (project TIN2017-85179-C3-2-R

Role of MUC1 rs4072037 polymorphism and serum KL-6 levels in patients with antisynthetase syndrome
Mucin 1/Krebs von den Lungen-6 (KL-6) is proposed as a serum biomarker of several interstitial lung diseases (ILDs), including connective tissue disorders associated with ILD. However, it has not been studied in a large cohort of Caucasian antisynthetase syndrome (ASSD) patients. Consequently, we assessed the role of MUC1 rs4072037 and serum KL-6 levels as a potential biomarker of ASSD susceptibility and for the differential diagnosis between patients with ILD associated with ASSD (ASSD-ILD?+) and idiopathic pulmonary fibrosis (IPF). 168 ASSD patients (149 ASSD-ILD?+), 174 IPF patients and 523 healthy controls were genotyped for MUC1 rs4072037 T?>?C. Serum KL-6 levels were determined in a subgroup of individuals. A significant increase of MUC1 rs4072037 CC genotype and C allele frequencies was observed in ASSD patients compared to healthy controls. Likewise, MUC1 rs4072037 TC and CC genotypes and C allele frequencies were significantly different between ASSD-ILD+ and IPF patients. Additionally, serum KL-6 levels were significantly higher in ASSD patients compared to healthy controls. Nevertheless, no differences in serum KL-6 levels were found between ASSD-ILD+ and IPF patients. Our results suggest that the presence of MUC1 rs4072037 C allele increases the risk of ASSD and it could be a useful genetic biomarker for the differential diagnosis between ASSD-ILD+ and IPF patients
HLA association with the susceptibility to anti-synthetase syndrome.
Objective: To investigate the human leukocyte antigen (HLA) association with anti-synthetase syndrome (ASSD). Methods: We conducted the largest immunogenetic HLA-DRB1 and HLA-B study to date in a homogeneous cohort of 168 Caucasian patients with ASSD and 486 ethnically matched healthy controls by sequencing-based-typing. Results: A statistically significant increase of HLA-DRB1*03:01 and HLA-B*08:01 alleles in patients with ASSD compared to healthy controls was disclosed (26.2% versus 12.2%, P = 1.56E–09, odds ratio–OR [95% confidence interval–CI] = 2.54 [1.84–3.50] and 21.4% versus 5.5%, P = 18.95E–18, OR [95% CI] = 4.73 [3.18–7.05]; respectively). Additionally, HLA-DRB1*07:01 allele was significantly decreased in patients with ASSD compared to controls (9.2% versus 17.5%, P = 0.0003, OR [95% CI] = 0.48 [0.31–0.72]). Moreover, a statistically significant increase of HLA-DRB1*03:01 allele in anti-Jo-1 positive compared to anti-Jo-1 negative patients with ASSD was observed (31.8% versus 15.5%, P = 0.001, OR [95% CI] = 2.54 [1.39–4.81]). Similar findings were observed when HLA carrier frequencies were assessed. The HLA-DRB1*03:01 association with anti-Jo-1 was unrelated to smoking history. No HLA differences in patients with ASSD stratified according to the presence/absence of the most representative non-anti-Jo-1 anti-synthetase autoantibodies (anti-PL-12 and anti-PL-7), arthritis, myositis or interstitial lung disease were observed. Conclusions: Our results support the association of the HLA complex with the susceptibility to ASSD.This study was partially supported by grants from the Foundation for Research in Rheumatology (FOREUM); SR-M is supported by funds of the RETICS Program [grant number RD16/0012/0009] from the `Instituto de Salud Carlos III´ (ISCIII), co-funded by the European Regional Development Fund (ERDF); BA-M is a recipient of a ‘López Albo’ Post-Residency Programme funded by Servicio Cántabro de Salud; VP-C is supported by a pre-doctoral grant from IDIVAL [grant number PREVAL 18/01]; LL-G is supported by funds of ISCIII, co-funded by ERDF [grant number PI18/00042]; OG is beneficiary of a grant funded by Xunta de Galicia, Consellería de Educación, Universidade e Formación Profesional and Consellería de Economía, Emprego e Industria (GAIN), GPC IN607B2019/10; EAR is partially supported by Versus Arthritis [grant number 20719] and by Scleroderma and Raynaud's UK [grant number BR11]; RL-M is a recipient of a Miguel Servet type I programme fellowship from the ISCIII, co-funded by the European Social Fund (ESF, ‘Investing in your future’) [grant number CP16/00033]
