Rhythmic ostensive gestures: How adults facilitate infants´ entrance into early triadic interactions
For decades, the literature on the emergence of triadic interactions considers the end of the first year of life as the time when children become able to communicate with others intentionally about a referent. Prior to that, children only relate in dyads, either with someone else or with an object. However, several researchers claim that referents are not naturally given in human communication and that they need to be established in interaction with others. In this study, we focus on earlier triadic interactions initiated by adults, when young babies still require an adult to bring the material world within their reach. In these early triadic interactions, ostensive gestures (with the object in the hand) are one of the first means of enabling the establishment of shared reference. Such gestures are easier to understand since sign (gesture) and referent (object) coincide. We conducted a longitudinal study with 6 babies filmed at 2, 3 and 4 months old in interaction with their mothers and a sounding object (a maraca). We analyzed different communicative initiatives by the adult and the child’s responses. The results show that children come to understand the adult’s communicative intention gradually through interaction. Adults include children in organized communicative “niches” based on ostensive actions, both through ostensive gestures and demonstrations of the use of the object. Consequently, the first shared understandings between adult and child take place around the object and its uses. Rhythm is a powerful tool used to structure the interaction. Eventually, adults provide space to children to actively interact with the sounding object themselves. These results highlight the importance of considering ostensive actions as a communicative tool that favors joint attention and action. They also bring some light to the interdependence between a child who actively perceives and acts, and the structured situation that the adult organizes for themThis study was supported by the program for the Training of University Teachers (Formación de

Musical dynamics in early triadic interactions: a case study
This version of the article has been accepted for publication, after peer review (when applicable) and is subject to Springer Nature’s AM terms of use, but is not the Version of Record and does not reflect post-acceptance improvements, or any corrections. The Version of Record is available online at: http://dx.doi.org/10.1007/s00426-019-01168-4Research of the last 30 years showed the importance of music for psychological development.
Communicative musicality studies described musical organisations in dyadic interactions (adult–baby).
However, other perspectives proposed that, from the beginning of life, there are early triadic interactions
(adult–object–baby) that should also be analysed. Following previous research, we hypothesised that
early triadic interactions have a structured musical organisation. We recorded a 2 month-old child
interacting with his mother and an object in their home and performed a microgenetic
quantitative–qualitative analysis. Given the child’s age, we focused on musical characteristics of
the mother’s actions. To our knowledge, this is the first study to combine data processing provided by
ELAN, Finale, and Matlab-MIRtoolbox. Our analysis shows that the child participates in triadic
interactions in which the mother communicates about and through the maraca using musical
resources in increasingly complex ways. Musical structuring happens at the intersegment,
intrasequence, and intersequence levels, and involves different musical parameters. We suggest
musical organisation in early triadic interactions follows a holographic structure in which each
piece carries information about dynamic processes of different timescales. Results highlight the
importance of considering objects and their uses to better understand early communicative musicalit
Reflexiones y propuestas para mejorar procesos de adecuación socio-técnica y políticas públicas de energías renovables : Talleres participativos ASADES 2012-2013
El trabajo presenta los resultados y aprendizajes generados a partir de la realización de talleres participativos de reflexión y discusión sobre los procesos de ‘transferencia tecnológica’ y políticas públicas de energías renovables. La iniciativa fue planteada por un equipo multidisciplinario e interinstitucional preocupado por esta temática y conformado espontáneamente en el marco del tema 12 de la reunión de ASADES. Los talleres estuvieron orientados a promover la interacción entre actores del sector científico-académico que desarrollan acciones en ER, motivando un abordaje socio- técnico de los procesos. Entre los resultados más significativos se destacan: avances en la reflexión y conceptualización del tema, análisis general de los proyectos y políticas de energías renovables en el país, y planteamiento de propuestas y estrategias para mejorar la articulación ‘ciencia-tecnología-sociedad’.This paper presents the results and learnings generated from the realization of workshops for reflection and discussion on the process of 'technology transfer' and renewable energy policies. The initiative was raised by a multidisciplinary and inter-institutional team worried about this subject, which was formed spontaneously in the work table 12 in the ASADES meeting. The workshops were designed to promote interaction between actors of the scientific and academic sectors who develop actions in renewable energies, motivating a socio-technical approach. The most significant results are: advances in reflection and conceptualization of the topic, overview of projects and public policies of renewable energies in the country, and formulation of proposals and strategies to improve the ‘science-technology-society’ articulation.Asociación Argentina de Energías Renovables y Medio Ambiente (ASADES
Preclinical studies of toxicity and safety of the AS-48 bacteriocin
The in vitro antimicrobial potency of the bacteriocin AS-48 is well documented, but its clinical application
requires investigation, as its toxicity could be different in in vitro (haemolytic and antibacterial activity in
blood and cytotoxicity towards normal human cell lines) and in vivo (e.g. mice and zebrafish embryos)
models. Overall, the results obtained are promising. They reveal the negligible propensity of AS-48 to
cause cell death or impede cell growth at therapeutic concentrations and support the suitability
of this peptide as a potential therapeutic agent against several microbial infections, due to its
selectivity and potency at low concentrations. In addition, AS-48 exhibits
low haemolytic activity in whole blood and does not induce nitrite accumulation in non-stimulated
RAW macrophages, indicating a lack of pro-inflammatory effects. The unexpected heightened sensitivity
of zebrafish embryos to AS-48 could be due to the low differentiation state of these cells. The low cytotoxicity
of AS-48, the absence of lymphocyte proliferation in vivo after skin sensitization in mice, and the
lack of toxicity in a murine model support the consideration of the broad spectrum antimicrobial peptideThis research was funded by the Spanish Ministry of Economy

Are Strength Indicators and Skin Temperature Affected by the Type of Warm-Up in Paralympic Powerlifting Athletes?
(1) Background: the present study aimed to evaluate the effect of different types of warm-ups on the strength and skin temperature of Paralympic powerlifting athletes. (2) Methods: the participants were 15 male Paralympic powerlifting athletes. The effects of three different types of warm-up (without warm-up (WW), traditional warm-up (TW), or stretching warm-up (SW)) were analyzed on static and dynamic strength tests as well as in the skin temperature, which was monitored by thermal imaging. (3) Results: no differences in the dynamic and static indicators of the force were shown in relation to the different types of warm-ups. No significant differences were found in relation to peak torque (p = 0.055, F = 4.560, η2p = 0.246 medium effect), and one-repetition maximum (p = 0.139, F = 3.191, η2p = 0.186, medium effect) between the different types of warm-ups. In the thermographic analysis, there was a significant difference only in the pectoral muscle clavicular portion between the TW (33.04 ± 0.71 °C) and the WW (32.51 ± 0.74 °C) (p = 0.038). The TW method also presented slightly higher values than the SW and WW in the pectoral muscles sternal portion and the deltoid anterior portion, but with p-value > 0.05. (4) Conclusions: the types of warm-ups studied do not seem to interfere with the performance of Paralympic Powerlifting athletes. However, the thermal images showed that traditional warm-up best meets the objectives expected for this preparation phase.post-print1305 K
Common genetic variation in KATNAL1 non-coding regions is involved in the susceptibility to severe phenotypes of male infertility
Free PMC article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9546047/Background: Previous studies in animal models evidenced that genetic mutations
of KATNAL1, resulting in dysfunction of its encoded protein, lead to male infertility
through disruption of microtubule remodelling and premature germ cell exfoliation.
Subsequent studies in humans also suggested a possible role of KATNAL1 single nucleotide polymorphisms in the development of male infertility as a consequence of
severe spermatogenic failure.
Objectives: The main objective of the present study is to evaluate the effect of the
common genetic variation of KATNAL1 in a large and phenotypically well-characterised
cohort of infertile men because of severe spermatogenic failure.
Materials and methods: A total of 715 infertile men because of severe spermato genic failure, including 210 severe oligospermia and 505 non-obstructive azoospermia
patients, as well as 1058 unaffected controls were genotyped for three KATNAL1
single-nucleotide polymorphism taggers (rs2077011, rs7338931 and rs2149971).
Case–control association analyses by logistic regression assuming different models
and in silico functional characterisation of risk variants were conducted.
Results: Genetic associations were observed between the three analysed taggers and
different severe spermatogenic failure groups. However, in all cases, the haplotype
model (rs2077011*C | rs7338931*T | rs2149971*A) better explained the observed
associations than the three risk alleles independently. This haplotype was associated
with non-obstructive azoospermia (adjusted p = 4.96E-02, odds ratio = 2.97), Sertoli cell only syndrome (adjusted p = 2.83E-02, odds ratio = 5.16) and testicular sperm
extraction unsuccessful outcomes (adjusted p = 8.99E-04, odds ratio = 6.13). The in
silico analyses indicated that the effect on severe spermatogenic failure predisposition
could be because of an alteration of the KATNAL1 splicing pattern.
Conclusions: Specific allelic combinations of KATNAL1 genetic polymorphisms may
confer a risk of developing severe male infertility phenotypes by favouring the
overrepresentation of a short non-functional transcript isoform in the testis.This work was supported by the Spanish Ministry of Economy and
