OPENMODS 2.0 “Instrument Jamming Meeting” report
Major achievements
The feedback provided by potential users on their needs was very much appreciated. They
underlined the importance of having:
â—Ź an easy to deploy instrument (i.e.: from small fishing boats);
â—Ź multi-parameter sensors in ONE device;
â—Ź less maintenance effort
and prioritized the variables to measure.
Although, there are technical limitations and different solutions and there is no one tool that
can do everything, which is low cost, has high resolution and low maintenance, the
outcomes of the platforms/sensors/communications working group meet the main
requirements that emerged.
Priority was given to:
â—Ź a platform that will operate in drifter mode which is extremely easy to deploy and
perfect for studies associated with search and rescue operations (another need that
has emerged). It also constantly guarantees the knowledge of the instrument position.
The platform can be easily converted into the moored mode.
â—Ź temperature and pressure sensors. The sensors will be low -cost with the idea to
replace them rather than calibrate them;
â—Ź LoRaWAN communications preferably with Bluetooth integration for the in-situ
download of the data

On natural metalinguistic abilities in aphasia: a preliminary study
Natural metalinguistic abilities, which are put into play without explicit instructions, constitute the cognitive basis for a 'reflexive' use of language, a particular manifestation of the executive function when applied to language and verbal behaviour. This reflexive use entails a specific attentional activity by speakers and hearers with regard to linguistic outputs, and an intentional experience-based control over the language use. Putting into play natural metalinguistic abilities can be considered a significant factor for explaining different kinds of adaptive processes. Our results permit us to conclude that an impairment of metalinguistic abilities is involved in aphasia to different degrees. Moreover, the examination of preserved metalinguistic abilities provides an alternative way for assessing the degree of severity of impaired communicative behaviour by people with aphasia. Our procedure, presumably, will also be useful for suggesting new factors when designing therapeutic programmes
Structural Disorder Provides Increased Adaptability for Vesicle Trafficking Pathways
Vesicle trafficking systems play essential roles in the communication between the organelles of eukaryotic cells and also
between cells and their environment. Endocytosis and the late secretory route are mediated by clathrin-coated vesicles,
while the COat Protein I and II (COPI and COPII) routes stand for the bidirectional traffic between the ER and the Golgi
apparatus. Despite similar fundamental organizations, the molecular machinery, functions, and evolutionary characteristics
of the three systems are very different. In this work, we compiled the basic functional protein groups of the three main
routes for human and yeast and analyzed them from the structural disorder perspective. We found similar overall disorder
content in yeast and human proteins, confirming the well-conserved nature of these systems. Most functional groups
contain highly disordered proteins, supporting the general importance of structural disorder in these routes, although some
of them seem to heavily rely on disorder, while others do not. Interestingly, the clathrin system is significantly more
disordered (,23%) than the other two, COPI (,9%) and COPII (,8%). We show that this structural phenomenon enhances
the inherent plasticity and increased evolutionary adaptability of the clathrin system, which distinguishes it from the other
two routes. Since multi-functionality (moonlighting) is indicative of both plasticity and adaptability, we studied its
prevalence in vesicle trafficking proteins and correlated it with structural disorder. Clathrin adaptors have the highest
capability for moonlighting while also comprising the most highly disordered members. The ability to acquire tissue specific
functions was also used to approach adaptability: clathrin route genes have the most tissue specific exons encoding for
protein segments enriched in structural disorder and interaction sites. Overall, our results confirm the general importance of
structural disorder in vesicle trafficking and suggest major roles for this structural property in shaping the differences of
evolutionary adaptability in the three routes
UtilizaciĂłn de caprinos para el control de vegetaciĂłn indeseable
The benefits of using goats ( Capra hircus hircus ) to control
undesirable vegetation in many different environmental situations are
well documented by research data. Nonetheless, this approach is
severely underutilized. Environmental concerns and the increased costs
of herbicides and mechanical control methods provide new opportunities
to use goats as biological agents for the control of unwanted
vegetation. The goat lends itself to conservation grazing better than
any other domestic livestock species when utilized in a sustainable
manner. Goats can be quite destructive, however, but any environmental
hazard associated with goats is essentially a failure in adequate
management by man.A pesar de que existe diversa informaciĂłn cientĂfica, que
reporta los beneficios de utilizar caprinos ( Capra hircus hircus )
para controlar vegetaciĂłn indeseable, en diversas condiciones
ambientales, lamentablemente este enfoque no es utilizado
frecuentemente. La preocupaciĂłn por el ambiente, y los incrementos
en los costos de los herbicidas y de los métodos de control de
malezas mecánicos, proporcionan nuevas oportunidades para el
empleo de caprinos como agentes para el control biolĂłgico de
vegetaciĂłn indeseable. Los caprinos tienden a realizar un pastoreo
conservativo “autocontrolado”, mejor que otras especies de
ganado doméstico, cuando se utiliza un enfoque sustentable; bajo
otras circunstancias, los caprinos podrĂan llegar a ser
destructivos. Sin embargo, cualquier riesgo ambiental asociado con los
caprinos, esta vinculado, en esencia, a un manejo inadecuado de esta
especie por el hombre
Hearing loss in children with congenital cytomegalovirus infection: An 11-year retrospective study based on laboratory database of a tertiary paediatric hospital
Congenital cytomegalovirus infection is considered the main cause of infantile non-genetic neurosensory hearing loss. Although this correlation was described more than 50 years ago, the natural history of internal ear involvement has not yet been fully defined. Hearing loss is the most frequent sequela and is seen in a variable percentage up to 30%; the hearing threshold is characterised by fluctuations or progressive deterioration. The purpose of this study was to evaluate the prevalence of hearing loss in cases of congenital CMV infection from Modena county, starting from the database of the microbiology and virology reference laboratory. All children undergoing urine testing for suspected CMV infection or viral DNA testing on Guthrie Card in the period between January 2004 and December 2014 were enrolled in the study. Family paediatricians were contacted and asked about clinical information on the possible presence at birth or subsequent occurrence of hearing loss, excluding cases where this was not possible. The results showed an annual prevalence of congenital cytomegalovirus infection among suspected cases that was stable over time despite the progressive increase in subjects tested. The prevalence of hearing loss was in line with the literature, whereas in long-term follow-up cases of moderate, medium-to-severe hearing loss with late onset were not detected. The introduction of newborn hearing screening in the county has allowed early diagnosis of hearing loss at birth as non-TEOAE-born births underwent a urine virus test. Moreover, despite all the limitations of the study, we can conclude that European epidemiological studies are needed to better define the relationship between congenital CMV infection and internal ear disease as the impact of environmental and genetic factors is still not entirely clarified
Forage Consumption and Its Effects on the Performance of Growing Swine-Discussed in Relation to European Wild Boar (Sus scrofa L.) in Semi-Extensive Systems: A Review
Simple Summary Outdoor-reared European wild boar (Sus Scrofa L.) is regarded as a delicacy by consumers due to its favourable meat properties and an association with high welfare standards. The rearing of wild boar on pasture has the potential to minimise input costs relative to conventional production systems. However, some pasture production systems have been found to perform poorly due to low growth rates. This review collates the available scientific evidence on pasture-based production of wild boar and domestic pigs, to identify factors that influence feed intake, performance, and behaviour. Factors explored include season/weather, dietary supplementation, grazing management, forage availability, herbage quality, and sward type. For example, the additional feed availability associated with pasture grazing has been shown to be a significant factor that positively correlates with dry matter intake of wild boar. This has been demonstrated to result in better feed conversion efficiency and reduced feed costs without reductions in growth rates compared to animals without access to pasture. Furthermore, the increased availability of favoured species in pasture may also promote dry matter intake. The long-term sustainability of wild boar production is dependent on the economic, social, and environmental viability of the systems. Pasture-based production systems may be one way by which this can be achieved, but only if implemented correctly. Due to its distinct properties, wild boar meat is considered a highly desirable consumer product, in a market that is expanding. Outdoor production is also favoured by consumers who value animal welfare and environmental sustainability when choosing meat products. There is evidence that farms that include pasture for grazing typically have reduced feeding costs. Such production systems can also be more environmentally sustainable as the input (pasture) is inedible to humans, compared to conventional indoor systems, which use human-edible feeds (e.g., soya). However, some wild boar farms have performed poorly compared to those rearing other swine such as hybrid wild boar and domestic pigs. Diet is central to all livestock production and is likely a significant influencing factor of wild boar performance, both in terms of forage consumption and nutritional composition. Other factors may also influence performance, such as weather, behaviour and grazing management. Wild boar production systems hold their own intrinsic value in a growing marketplace. However, information gathered through the study of wild boar has external applications in informing outdoor domestic pig production systems to encourage the use of pasture as part of the habitat of domestic pigs
What happens when the newborn hearing screening program is integrated with congenital Cytomegalovirus infection screening? Preliminary results in a tertiary hospital
Objective: Early diagnosis of congenital Cytomegalovirus (cCMV) infection related hearing loss has increased since the spread of newborn hearing screening (NHS) programs worldwide. However, since most newborns affected are asymptomatic at birth but may develop hearing loss later, some of them may elude the NHS. The aim of this study was to compare the results in two cohorts of children, in one of which all newborns who failed the NHS were tested for cCMV. Methods: We retrospectively compared the results of early diagnosis of cCMV-related hearing loss between two groups of patients at a high-volume centre. Group 1 included the first 3 years of activity without a targeted cCMV screening and was composed of children born between 2012 and 2014. Group 2 included neonates born between 2015 and 2017: in this group, those who failed the NHS underwent urine CMV analysis within 14 days. Results: There were 17,229 live births during the study period, 20 were diagnosed with cCMV infection, with a global prevalence of 1.1:1000. 72 neonates (0.42%) with hearing loss were identified, 7% of which were diagnosed with cCMV infection, 3/34 (8.8%) in group 1 and 2/38 (5.3%) in group 2 (p =.66). One newborn in group 2 was identified through the protocol. The percentage of patients affected by cCMV-related hearing loss diagnosed during the NHS showed non-significant differences in the two groups. Conclusion: Our results suggest that the suspicion index of cCMV infection in a tertiary hospital is currently high and neonatologists are able to identify most symptomatic cases which have higher risk of developing hearing loss. Coupling the cCMV screening and the NHS program is worthwhile as it allows early recognition of asymptomatic cases with hearing loss and subsequent immediate administration of antiviral therapy
