ConclusionsThis work responds to the pressing need to address the STH diagnostic issues put forward by the WHO Diagnostic Technical Advisory Group [8]. The data presented here contributes to the search for a new programmatic standard to support STH control. The lack of a gold standard for diagnosing T. trichiura and other STH infections poses a significant challenge in searching for a method that outperforms the traditional microscopy-based K-K.

In all areas where fishing activities overlap with feeding and/or breeding areas for pinnipeds (seals, sea lions, and walrus), there is a high probability of operational interactions (Harwood and Croxall 1988, Riedman 1990, Wickens 1995, Bjørge et al. 2002, Jackson et al. 2024).

AbstractIn this paper, we have performed an in-depth study of the complete set of the satellite DNA (satDNA) families (i.e. the satellitomes) in the genome of two barley species of agronomic value in a breeding framework, H. chilense (H1 and H7 accessions) and H. vulgare (H106 accession), which can be useful tools for studying chromosome associations during meiosis. The study has led to the analysis of a total of 18 satDNA families in H. vulgare, 25 satDNA families in H.

Una nueva publicación en Nature Genetics, titulada “A proposal for an inclusive working definition of genetic discrimination to promote a more coherent debate”, propone una definición concreta de este fenómeno que impacta derechos fundamentales como la dignidad, la justicia y la equidad. Esta publicación fue realizada por el Observatorio de Discriminación Genética, de la Facultad de Medicina de la Universidad McGill, en Canadá.

NGC 6357, a star-forming complex at ∼1.7 kpc from the Sun, contains giant molecular clouds and three prominent star clusters alongside HII regions, very massive stars and thousands of young stellar objects in different evolutionary stages. We present a combined infrared kinematic and time domain study of the line of sight towards this region enabled by the VVVX survey. In terms of kinematics, a novel discovery emerges: an asymmetrical distribution in the vector point diagram.

The study of different star-forming regions and their stellar populations, as well as the reconstruction of their star formation history and structure need astrometric and kinematic data with the lowest levels of uncertainty possible. Thanks to the Gaia satellite (Gaia Collaboration et al.

In the period between 2009 and 2015, several very high-energy (VHE >100 GeV) gamma-ray flaring events from the BL Lac object PKS 1424+240 were observed by the Cerenkov telescopes VERITAS and MAGIC. It had uncertain redshift (z) and using spectroscopical measurement, Paiano et al. (2017) found it to be z = 0.604.

We present a novel asymptotically anti–de Sitter black hole solution with conformally-coupled scalar fields in the first-order formalism of gravity in four dimensions. To do so, we consider a one-parameter extension of conformal transformations by exploiting the fact that the tetrad and spin connection are regarded as independent fields.
