Introduction: Complications related to airway management represent from 1 to 18%. Totaltrack® is a laryngeal video-mask device with, that allows intubate and ventilate patients with indirect vision through a camera, also have a port to introduce an esophagogastric aspiration probe. Material and methods: The device was evaluated in 57 ASA I-III patients from 18 to 65 years of age undergoing balanced general anesthesia, with and without predictors of difficult airway, without neuromuscular block, it has been made the difficult intubation predictor index before each procedure. During the direct laryngoscopy due to incidental extubation, the Cormack-Lehane assessment was performed. Once the results were obtained, an analysis was made of the use of Totaltrack® in the sealing pressures of the laryngeal mask and the success of tracheal intubation through the device. Results: Of the total number of patients analyzed. The insertion and ventilation were successful in all cases, the static leak and the maximum inflation pressures of the laryngeal mask component were 30 cm of air respectively. The tracheal intubation through the device was successful in all cases, with a mean intubation time of 4.5 ± 0.58 seconds. Gastric insufflation was not observed. The hemodynamic variability was not clinically significant. No significant side effects were reported, the Cormack-Lehane of the two patients incidentally extubated was III in both cases. Conclusions: Yes, the use of Totaltrack® was found useful in all cases. The use of Totaltrack® allows an optimal visualization of the airway, the intubation is not complicated and can be performed with rapid sequence, independently of the difficult intubation predictor index and the Cormack Lehane.

The medial entorhinal cortex (mEC) is a key structure which controls the communication between the hippocampus and the neocortex. During slow-wave sleep, it stands out from other cortical regions by exhibiting persistent activity that outlasts neocortical Up states, decoupling the entorhinal cortex-hippocampal interaction from the neocortex. Here, we compared the mechanisms involved in the maintenance of the Up state in the barrel cortex (BC) and mEC using whole cell recordings in acute mouse brain slices. Bath application of an NMDA receptor antagonist abolished Up states in the BC, and reduced the incidence but not the duration of Up states in the mEC. Conversely, blockade of kainate receptors decreased Up state duration in the mEC, but not in the BC. Voltage clamp recordings demonstrated the presence of a non-NMDA glutamate receptor-mediated slow excitatory postsynaptic current, sensitive to the selective kainate receptor antagonist UBP-302, in layer III neurons of the mEC, which was not observed in the BC. Moreover, we found that kainate receptor-mediated currents assist in recovery back to the Up state membrane potential following a current-induced hyperpolarisation of individual cells in the mEC. Finally, we were able to generate Up state activity in a network model of exponential integrate-and-fire neurons only supported by AMPA and kainate receptor-mediated currents. We propose that synaptic kainate receptors are responsible for the unique properties of mEC Up states. [ABSTRACT FROM AUTHOR]

The quality of an oocyte can be defined by its potential to produce a normal and viable embryo. In Oncorhynchus mykiss (Walbaum), oocyte quality is highly variable under both natural and aquaculture conditions. To ensure the competitiveness and sustainability of rainbow trout farming, new tools are needed to evaluate oocyte potential. Considering that the abundance of certain maternal mRNAs incorporated during oogenesis can determine egg quality, the aim of the present study was to assess if significant differences existed in the abundances of the maternal mRNAs pou2 and zorba in low and high quality O. mykiss eggs. Analyses determined that survival until the end of gastrulation varied significantly between high and low quality egg batches, and significant correlations were established with posterior early development events. The abundance of pou2 and zorba transcripts varied between high and low quality groups, with higher relative expression recorded in the low quality group. Additionally, the abundances of these transcripts were significantly correlated with survival until blastopore closure, the earliest ontogenetic event evaluated as a quality attribute for this salmonid species. This correlation is supported by participations reported for both proteins in other teleost fish during embryonic development. These results form a basis for complementary studies and permit proposing maternal pou2 and zorba mRNA as potential markers for O. mykiss egg quality. [ABSTRACT FROM AUTHOR]

Following the conquest of the town of Alcántara by the Military Order of the same name, its bridge became a considerable source of revenue as a result of the tolls imposed on passage over the same. An organization known as the "Alcaldía del Puente" was created to administer these tolls and remained in force until 1836. An examination of the "Alcaidía" makes it possible to appreciate the life of the bridge and understand its survival up to the present day. [ABSTRACT FROM AUTHOR]

Infectious salmon anaemia (ISA) is a serious disease of marine-farmed Atlantic salmon (Salmo salar) caused by ISA virus (ISAV), which belongs to the genus Isavirus, family Orthomyxoviridae. ISA is caused by virulent ISAV strains with deletions in a highly polymorphic region (HPR) of the hemagglutinin-esterase (HE) protein (designated virulent ISAV-HPRΔ). This study shows the historic dynamics of ISAV-HPRΔ and ISAV-HPR0 in Chile, the genetic relationship among ISAV-HPR0 reported worldwide and between ISAVHPR0 and ISAV-HPRΔ in Chile, and reports the 2013 ISA outbreak in Chile. The first ISA outbreak in Chile occurred from mid-June 2007 to 2010 and involved the virulent ISAVHPR7b, which was then replaced by a low pathogenic ISAV-HPR0 variant. We analyzed this variant in 66 laboratory-confirmed ISAV-HPR0 cases in Chile in comparison to virulent ISAV-HPRΔ that caused two new ISA outbreaks in April 2013. Multiple alignment and phylogenetic analysis of HE sequences from all ISAV-HPR0 viruses allowed us to identify three genomic clusters, which correlated with three residue patterns of ISAV-HPR0 (360PST362, 360PAN362 and 360PAT362) in HPR. The virus responsible for the 2013 ISAVHPRΔ cases in Chile belonged to ISAV-HPR3 and ISAV-HPR14, and in phylogenetic analyses, both clustered with the ISAV-HPR0 found in Chile. The ISAV-HPR14 had the ISAV-HPR0 residue pattern 360PAT362, which is the only type of ISAV-HPR0 variant found in Chile. This suggested to us that the 2013 ISAV-HPRΔ re-emerged from ISAV-HPR0 that is enzootic in Chilean salmon aquaculture and were not new introductions of virulent ISAVHPRΔ to Chile. The clinical presentations and diagnostic evidence of the 2013 ISA cases indicated a mixed infection of ISAV with the ectoparasite Caligus rogercresseyi and the bacterium Piscirickettsia salmonis, which underscores the need for active ISAV surveillance in areas where ISAV-HPR0 is enzootic, to ensure early detection and control of new ISA outbreaks, as it is considered a risk factor. This is the first report of ISA linked directly to the presence of ISAV-HPR0, and provides strong evidence supporting the contention that ISAVHPR0 shows a strong relationship to virulent ISAV-HPRΔ viruses and the possibility that it could mutate to virulent ISAV-HPRΔ.

The significance of meaningful work for quality of work life has been confirmed by research showing its importance both as regards to employee motivation, well-being, and commitment as well as organizational outcomes such as turnover intentions, citizenship behavior, and customer satisfaction. In explaining what makes work meaningful, Self-Determination Theory (SDT) provides a potent theoretical framework, linking meaningful work to the satisfaction of human psychological needs. Accordingly, we draw on SDT and research on prosocial behavior to examine what we identify as the four most potential psychological pathways to meaningful work: beneficence and the psychological needs for autonomy, competence, and relatedness. We tested these four antecedents in a three-waves longitudinal design among a large sample of Chilean workers (T1 N = 631, T2 N = 240, T3 N = 148). We found that both autonomy and beneficence prospectively predict subsequent meaningful work above and beyond the other two needs and baseline levels of meaningful work. These results advance theory on key psychological pathways to meaningful work and have important practical implications for how organizations and managers can foster meaningfulness in the workplace through cultivating autonomy and beneficence. • Provides a three-wave longitudinal examination of the key factors influencing meaningful work. • Demonstrates that autonomy prospectively predicts meaningful work. • Demonstrates that beneficence – sense of prosocial impact – prospectively predicts meaningful work.

The increase in irrigated crop areas, especially in countries such as Spain and Italy, has led to an increase in technological solutions for monitoring the irrigation. Furthermore, the centre pivot irrigation systems used in these crops have facilitated the daily work of farmers in recent years, however, the monitoring of these systems and the reporting of problems in their operation has become a key aspect during the growing season. For this reason, different monitoring solutions have been proposed from the area of Precision Agriculture and Information and Communication Technologies (ICTs). Nevertheless, it is necessary that these solutions take into account the digital divide their potential users may suffer and be low-cost solutions in order to be attractive to the end-users. This paper presents several low-cost solutions using novel user interfaces and wireless communication technologies for the monitoring of this type of irrigation systems. This paper presents the results obtained after the deployment of the proposed systems on a real environment and the main conclusions drawn after their use in irrigated maize crops. • LoRaWAN and GPS allow affordable monitoring systems for centre pivot irrigation. • Chatbots and voice assistants help to avoid the digital divide. • Edge Computing Devices and LPWANs enable new AMR solutions for water meters.
