A Semi-automated Organoid Screening Method Demonstrates Epigenetic Control of Intestinal Epithelial Differentiation

open access: yesFrontiers in Cell and Developmental Biology, 2021
Intestinal organoids are an excellent model to study epithelial biology. Yet, the selection of analytical tools to accurately quantify heterogeneous organoid cultures remains limited.

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Stem cells and the origin of gliomas: A historical reappraisal with molecular advancements. [PDF]

open access: yes, 2009
The biology of both normal and tumor development clearly possesses overlapping and parallel features. Oncogenes and tumor suppressors are relevant not only in tumor biology, but also in physiological developmental regulators of growth and differentiation.

Molecular biology for hpv typing in focal epithelial hyperplasia [PDF]

open access: yesTurkish Journal of Pathology, 2015
Parichehr Ghalayani and colleagues (Volume 31, Number 1, Pages:060-063) report three interesting cases of focal epithelial hyperplasia (FEH) diagnosed through clinical and microscopic analysis (1). We would like to emphasize that, although the age and ethnicity of the patient may support the clinical suspicion of FEH, the histopathological features of ...

Complexities of Type I Interferon Biology: Lessons from LCMV

open access: yesViruses, 2019
Over the past decades, infection of mice with lymphocytic choriomeningitis virus (LCMV) has provided an invaluable insight into our understanding of immune responses to viruses.

Structural Biology of Bacterial Type IV Secretion Systems.

open access: yesAnnual Review of Biochemistry, 2015
Type IV secretion systems (T4SSs) are large multisubunit translocons, found in both gram-negative and gram-positive bacteria and in some archaea. These systems transport a diverse array of substrates from DNA and protein-DNA complexes to proteins, and ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Jane Claire Dirks\u27s Correspondence with Stanley G. Jewett [PDF]

open access: yes, 2015
This exchange between Jane Claire Dirks (later Jane Claire Dirks-Edmunds) and Stanley G. Jewett, a biologist with Region 1 of the Fish and Wildlife Service (serving Oregon and five other states), is an example of the type of correspondence Dirks had with

On Kinetic Equations Modeling Evolution of Systems in Mathematical Biology

open access: yes, 2013
We develop a rigorous formalism for the description of the kinetic evolution of interacting entities modeling systems in mathematical biology within the framework of the evolution of marginal observables.

Scientific photography and astronomy: Technology applied to understanding the universe

open access: yesMètode Science Studies Journal: Annual Review
In 1925, Edwin Hubble took the first step towards increasing the size of the known universe by several orders of magnitude using the precarious photographic methods available at the time: glass plates and photosensitive emulsions.
