Current Trends in Aerogel Use in Heritage Buildings: Case Studies from the Aerogel Architecture Award 2021.

Silica aerogels are high-performance thermal insulation materials that can be used to provide unique solutions in the envelopes of buildings when space is limited. They are most often applied in historic buildings due to thin insulation thicknesses and since they are compatible with historic structures. In 2021, the first Aerogel Architecture Award was held at Empa in Switzerland in order to collect, evaluate and award outstanding uses of this relatively new building material.

SLAMseq resolves the kinetics of maternal and zygotic gene expression during early zebrafish embryogenesis.

The maternal-to-zygotic transition (MZT) is a key developmental process in metazoan embryos that involves the activation of zygotic transcription (ZGA) and degradation of maternal transcripts. We employed metabolic mRNA sequencing (SLAMseq) to deconvolute the compound embryonic transcriptome in zebrafish. While mitochondrial zygotic transcripts prevail prior to MZT, we uncover the spurious transcription of hundreds of short and intron-poor genes as early as the 2-cell stage.

Evaluation of In Vitro Tools to Predict the In Vivo Absorption of Biopharmaceuticals Following Subcutaneous Administration.

Purpose: For injectable biopharmaceuticals, the subcutaneous route of administration is increasingly preferred over intravenous administration. However, one of the challenges in the development of subcutaneously administered biopharmaceuticals is a reduced bioavailability, which is difficult to predict. Since animal models do not reliably reflect bioavailability in patients, in vitro models could help to develop drug candidates.

NMD is required for timely cell fate transitions by fine-tuning gene expression and regulating translation.

Cell fate transitions depend on balanced rewiring of transcription and translation programs to mediate ordered developmental progression. Components of the nonsense-mediated mRNA decay (NMD) pathway have been implicated in regulating embryonic stem cell (ESC) differentiation, but the exact mechanism is unclear. Here we show that NMD controls expression levels of the translation initiation factor and its premature termination codon-encoding isoform ( ).

Sports Medicine Research Practices for Categorizing Transgender and/or Intersex Participants.

Context: Approximately 1 to 1.4 million individuals (0.58% of the population) in the United States identify as transgender, yet no literature could be found regarding how researchers should adapt clinical research studies when intersex or transgender individuals volunteer as participants.
