Distribution of phosphate solubilizer fungi on soil microhabitats in two landscapes from Guaviare, Colombia

open access: yesActa Biológica Colombiana, 2002
The distribution of the phosphate solubilizer mycobiota in two different soil microhabitats present in Guaviare, Colombia, were studied. Twelve samples from Arazá rhizosphere (Eugenia stipitata McVaugh) and from soil without roots were processed using ...

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

Effects of Partial Mortality on Growth, Reproduction and Total Lipid Content in the Elkhorn Coral Acropora palmata

open access: yesFrontiers in Marine Science, 2018
Partial mortality (PM) is increasingly common in the Elkhorn coral Acropora palmata and, depending on the causative agent, is potentially lethal. The effects of PM on growth, reproduction and total lipid content in A.

Topography‐Regulated Screening Platform for Myoblast Contact Guidance

open access: yesAdvanced Materials Technologies, EarlyView.
This study develops a topography‐regulated screening platform (12 gradients in 96‐topography‐well plate) enabling analysis of skeletal muscle morphogenesis. The topography‐induced cell morphology changed, cell polarization, and myotube differentiation, establishing an evaluative framework for generating pathologically relevant myotube phenotypes to ...

The Black Man's Burden - The cost of colonization of French West Africa for French taxpayers [PDF]

open access: yes
Was colonization very costly for the metropole? This view has been widely accepted among French historians even though little empirical evidence has been provided.

Two‐Photon Polymerized Microvascular Environments for Multicellular Modeling of the Blood–Brain Tumor Barrier

open access: yesAdvanced Materials Technologies, EarlyView.
Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

open access: yesAdvanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

Law, Endowments, and Property Rights [PDF]

open access: yes
While scholars have hypothesized about the sources of variation in property rights for over 2500 years, it is only very recently that researchers have begun to test these theories empirically.
