Transcriptional Regulation of Genes Encoding Axonemal Central Apparatus Prot...Dra. Ruth Jaimez Melgoza
This document describes a study examining the transcriptional regulation of genes encoding axonemal central apparatus proteins. The researchers analyzed the promoter region of the PF20 gene, which encodes proteins important for sperm motility. They tested luciferase reporter activity driven by varying lengths of the PF20 promoter region in different cell types, and in the presence of potential transcription factors like PF20s, hFH-4, and SPZ1. They found the 0.2-0.3 kb region of the PF20 promoter responded most strongly to hFH-4, suggesting this region contains a response element for this transcription factor. Further mutational analysis of this region could help map the specific response element.

This document discusses single cell genomics and describes QIAGEN kits that can be used to analyze individual genomes from single cells. The kits use REPLI-g technology to overcome typical challenges in whole genome amplification and whole transcriptome amplification from single cells, such as low and uneven coverage and allelic dropout. The technology provides high yields and uniform coverage with low base copying errors compared to other methods like MALBAC. The kits allow characterization of individual genomes without cell culturing and have applications in cancer research, microbial analysis, and studying cellular heterogeneity.
The document proposes new tools for analyzing HIV-1 sequences clinically using geometric representations of DNA sequences called W-curves and clustering sequences using the Traveling Salesman Problem. The existing tools for analyzing HIV sequences make assumptions that do not apply to HIV and are not suitable for clinical analysis. The W-curve represents DNA as a geometric curve in 3D space, allowing alignment and comparison without assumptions. Clustering sequences using the TSP problem groups similar sequences and can identify progression towards drug resistance over time.
The TRP53 gene contains 11 exons and 10 introns. Exon 1 is 128 base pairs and exon 11 is 523 base pairs, which is the longest exon. The introns range in size from 5 base pairs to 793 base pairs. The gene is located on chromosome 11 in humans and encodes a tumor protein involved in regulating the cell cycle and suppressing tumor formation.
The document contains the sequence of the rice GADPH gene. Primers were designed to amplify a 188 base pair region located between base pairs 353-540. The primers and a hybridization probe were checked for hairpins, self-dimers, and restriction sites to validate their specificity and performance.
Translation takes place in the cytoplasm of the cell. The mRNA code is read by the ribosome three nucleotides at a time. tRNAs bring amino acids to the ribosome based on complementary base pairing between the tRNA's anticodon and the mRNA codon. Through this process, the mRNA code is translated into a polypeptide chain of amino acids.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
