The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

open access: yesBiological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

The [Not So] Hidden Curriculum of the Legalist State in the Book of Lord Shang and the Han-Fei-Zi [PDF]

open access: yes, 2018
This paper loosely draws some parallels between the experience of a subject in a so-called “Legalist” state with that of a contemporary student in Western schooling today.

Biophysical processes of morphogenesis in lizard lungs

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Novel skin defense peptides and microbiota contribute to disease resilience of the Ngäbe-Buglé leopard frog

open access: yesFrontiers in Amphibian and Reptile Science
Some of the amphibian populations in Panama are demonstrating slow recovery decades after severe declines caused by the invasion of the fungal pathogen Batrachochytrium dendrobatidis (Bd).

Frog Culture: A Big Leap Needed [PDF]

open access: yes, 1988
Though the croak-music of frogs has long back subsided in the waterbodies of our countryside, we hear now and then some noise about frogs made by seafood exporters.

The effect of trait choice on hybrid species distribution model projections under climate change

open access: yesEcography, EarlyView.
Species distribution models (SDMs) have been increasingly combined with thermal performance data to enhance their transferability and to provide a physiological explanation for the predicted geographic patterns. Yet, while it is widely acknowledged that thermal sensitivities may vary among biological traits, it remains largely unexplored to what extent

The ribosome biogenesis factor Nol11 is required for optimal rDNA transcription and craniofacial development in Xenopus. [PDF]

open access: yesPLoS Genetics, 2015
The production of ribosomes is ubiquitous and fundamental to life. As such, it is surprising that defects in ribosome biogenesis underlie a growing number of symptomatically distinct inherited disorders, collectively called ribosomopathies. We previously

Capillary Electrophoresis With Amperometric Detection for Neurotransmitter Analysis: Principles, Electrode Materials, Methodologies, and Applications

open access: yesELECTROPHORESIS, EarlyView.
This review provides a comprehensive summary of monoamine neurotransmitter analysis by capillary electrophoresis with amperometric detection. Fundamental principles of amperometric detection, electrode positioning strategies, and approaches to high‐voltage decoupling are described, followed by a critical comparison of electrode materials, selection of ...
