Multi-scale modeling of Snail-mediated response to hypoxia in tumor progression [PDF]

arXiv
Tumor cell migration within the microenvironment is a crucial aspect for cancer progression and, in this context, hypoxia has a significant role. An inadequate oxygen supply acts as an environmental stressor inducing migratory bias and phenotypic changes.

De Novo Whole Genome Assemblies of Unusual Case‐Making Caddisflies (Trichoptera) Highlight Genomic Convergence in the Composition of the Major Silk Gene (h‐fibroin)

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
The major silk gene, h‐fibroin, was annotated in high‐quality genomes of two unusual case‐making Trichoptera. H‐Fibroin of Limnocentropus insolitus shows a similar amino acid composition to other case‐making species, while the amino acid composition of h‐fibroin of Phryganopsyche brunnea resembles that of retreat‐making species.

An Account of Roman Surgical Treatments for Ozena: Historical Review

The Laryngoscope, EarlyView.
This historical study investigates ancient Roman surgical techniques for treating ozena as described by Celsus, with a focus on its historical and etymological context. Independent translation and archaeological evidence contextualize two ancient procedures: closed nasal cauterization using a heated probe and an open approach involving dissection and ...

Nutrient inversion but not warming drive changes in periphyton biomass and composition in shallow lake mesocosms

Limnology and Oceanography, EarlyView.
Abstract Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutrient availability in contrasting warming scenarios can contribute to the development of more efficient techniques for the restoration of lakes in a

Turbulent homeomorphisms and the topological snail [PDF]

arXiv
The topological snail is a geometric universal plane object, described by matrices in the projective special linear group with integer coefficients. It has many nice properties : in the case of three points, it natually defines a representation of the mapping-class group. From a dynamical point of view, it gives a description of the set of fixed points

Pteropods as early‐warning indicators of ocean acidification

Limnology and Oceanography, EarlyView.
Abstract Aragonite undersaturation (Ωar$$ {\Omega}_{\mathrm{ar}} $$ <$$ < $$ 1) events are projected to rapidly increase in frequency and duration in the Antarctic Weddell Sea by 2050. Thecosome pteropods (pelagic snails) are bioindicators of ocean acidification (OA) because their aragonite shell dissolves easily at low Ωar$$ {\Omega}_{\mathrm{ar ...
