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 explanation of a particular phenomenon ('causal mechanism').

Mechanism and Finality in Biology

open access: yesAzafea: Revista de Filosofía, 2011
This article defends a teleological approach which is compatible with our scientific image. It is held that organisms can be depicted as autonomous systems in which occurs autorregulation processes and exhibits a teleological behaviour oriented to an ...

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 ...

Systems biology and mechanics of growth [PDF]

open access: yesWIREs Systems Biology and Medicine, 2015
In contrast to inert systems, living biological systems have the advantage to adapt to their environment through growth and evolution. This transfiguration is evident during embryonic development, when the predisposed need to grow allows form to follow function.

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.

Mechanisms in molecular biology [PDF]

open access: yes, 2017
The new mechanistic philosophy is divided into two largely disconnected projects. One deals with a metaphysical inquiry into how mechanisms relate to issues such as causation, capacities and levels of organization, while the other deals with epistemic issues related to the discovery of mechanisms and the intelligibility of mechanistic representations ...

Ferroptosis: mechanisms, biology and role in disease

open access: yesNature Reviews Molecular Cell Biology, 2021
The research field of ferroptosis has seen exponential growth over the past few years, since the term was coined in 2012. This unique modality of cell death, driven by iron-dependent phospholipid peroxidation, is regulated by multiple cellular metabolic pathways, including redox homeostasis, iron handling, mitochondrial activity and metabolism of amino
