Process of quantitative evaluation of validity of rock cutting model [PDF]
Acta Montanistica Slovaca, 2012 Most of complex technical systems, including the rock cutting process, are very difficult to describe mathematically due to limitedhuman recognition abilities depending on achieved state in natural sciences and technology.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa
FEBS Letters, EarlyView.Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

Rock's pill that rocked the world
South African Medical Journal, 2010 I was a rookie doctor on the goldmines in the early 1960s. Part of my duties was to look after the families in the villages of the Anglo American mines at Welkom in the Free State. Their invariably large numbers of children prompted me to enquire whether they wished to have assistance in family planning.

FEBS Letters, EarlyView.Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

El grito de la música, un golpe de emancipación
Comhumanitas, 2019 Esta exposición transcurre en los «márgenes», en el pensamiento y en la penumbra de un acontecimiento. Aquella dictadura militar (1976-1983) que envolvió a la sociedad argentina, arrebatando los derechos y la justicia de cada uno de los ciudadanos.

Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
FEBS Letters, EarlyView.Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

FEBS Letters, EarlyView.Mutations in the C9orf72 gene represent the most common genetic cause of amyotrophic lateral sclerosis (ALS), a fatal neurodegenerative disease. Using patient‐derived neurons and C. elegans models, we find that the nucleoporin Nup107 is dysregulated in C9orf72‐associated ALS. Conversely, reducing Nup107 levels mitigates disease‐related changes.
