Material‐Induced Nuclear Deformation Controls Chromatin Architecture in Adipose Stem Cells

open access: yesAdvanced Science, EarlyView.
Tuning cell and cytoskeleton mechanics modulated nuclear shape and heterochromatin organization in ASCs. Distinct cytoskeletal architectures induced nuclear morphologies from oblate to prolate ellipsoids. Large elongated cells with a structured actin cap exhibited high nuclear strain, driving nuclear envelope deformation and heterochromatin ...

Assessing Agricultural Green Total Factor Productivity in Latin America

open access: yesAgribusiness, EarlyView.
ABSTRACT The agricultural sector in Latin America plays a vital role in ensuring food security while impacting the environment. However, there remains a lack of analysis regarding the inputs responsible for pollution within its sub‐technologies. Hence, this article aims to assess agricultural green total factor productivity (TFP) through a novel ...

DNA metabarcoding reveals greater plant diversity than morphological seed analysis of bird feces

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise Fruit‐eating birds drive seed dispersal in recovering tropical ecosystems, shaping forest regeneration. Molecular techniques, such as DNA metabarcoding, enable diet analysis from feces and can provide complementary frugivory data where dispersal is infrequent, as well as aid in seed identification in hyper‐diverse regions lacking ...

No. 03: Urban Food Deserts and Climate Change in African Cities [PDF]

open access: yes, 2016
The underlying assumption in much of the Euro-American food deserts literature is that urban food deserts are dynamic spaces, expanding and contracting with the advent and withdrawal of supermarkets. This discussion paper argues that to tie such dynamism

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

open access: yesThe Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...
