The Concept of Mechanism in Biology [PDF]

open access: yesStudies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences, 2012
The concept of mechanism in biology has three distinct meanings. It may refer to a philosophical thesis about the nature of life and biology (‘mechanicism’), to the internal workings of a machine-like structure (‘machine mechanism’), or to the causal ...

CRISPR-Cas: biology, mechanisms and relevance [PDF]

open access: bronzePhilosophical Transactions of the Royal Society B: Biological Sciences, 2016
Prokaryotes have evolved several defence mechanisms to protect themselves from viral predators. Clustered regularly interspaced short palindromic repeats (CRISPR) and their associated proteins (Cas) display a prokaryotic adaptive immune system that memorizes previous infections by integrating short sequences of invading genomes—termed spacers—into the ...

Identification of quiescent FOXC2+ spermatogonial stem cells in adult mammals

open access: yeseLife, 2023
In adult mammals, spermatogenesis embodies the complex developmental process from spermatogonial stem cells (SSCs) to spermatozoa. At the top of this developmental hierarchy lie a series of SSC subpopulations.

SPF45/RBM17-dependent, but not U2AF-dependent, splicing in a distinct subset of human short introns

open access: yesNature Communications, 2021
The length distribution of human pre-mRNA introns is very extensive. The authors demonstrate that splicing in a subset of short introns is dependent on SPF45 (RBM17), which replaces authentic U2AF-heterodimer on the truncated poly-pyrimidine tracts and ...

SARS-CoV-2: from its discovery to genome structure, transcription, and replication

open access: yesCell & Bioscience, 2021
SARS-CoV-2 is an extremely contagious respiratory virus causing adult atypical pneumonia COVID-19 with severe acute respiratory syndrome (SARS). SARS-CoV-2 has a single-stranded, positive-sense RNA (+RNA) genome of ~ 29.9 kb and exhibits significant ...

Mechanics rules cell biology [PDF]

open access: yesBMC Sports Science, Medicine and Rehabilitation, 2010
Cells in the musculoskeletal system are subjected to various mechanical forces in vivo. Years of research have shown that these mechanical forces, including tension and compression, greatly influence various cellular functions such as gene expression, cell proliferation and differentiation, and secretion of matrix proteins.

Mechanics in biology [PDF]

open access: yesEurophysics News, 2020
Mechanics plays a key role in life, from simple tasks like providing protective shielding to highly complex ones such as cell division. To understand mechanical properties on the organism level, we need to zoom in to its constituent cells, then zoom back out to see how they collectively build tissues.

Transcriptional analysis and target genes discovery of Pseudomonas aeruginosa biofilm developed ex vivo chronic wound model

open access: yesAMB Express, 2021
Bacterial biofilms formation is one of the major reasons for treatment failure in chronic wound infections. Therefore, diagnostic biomarkers remain the best option for prevention and treatment of chronic wound infections by biofilms.
