Integrating Melt Electrowriting and Fused Deposition Modeling to Fabricate Hybrid Scaffolds Supportive of Accelerated Bone Regeneration. [PDF]

Adv Healthc Mater
This work outlines the development of a hybrid scaffold consisting of a micro‐fibrous core made using melt electrowriting (MEW) and an outer shell made using fused deposition modeling (FDM). This study demonstrates the potential of integrating different additive manufacturing approaches for the development of regenerative biomaterials, and in ...

Linking Endotoxins, African Dust PM10 and Asthma in an Urban and Rural Environment of Puerto Rico

Mediators of Inflammation, Volume 2015, Issue 1, 2015., 2015
African Dust Events (ADE) are a seasonal phenomenon that has been suggested to exacerbate respiratory and proinflammatory diseases in Puerto Rico (PR). Increases in PM10 concentration and the effects of biological endotoxins (ENX) are critical factors to consider during these storms.

On Colour, Category Effects, and Alzheimer’s Disease: A Critical Review of Studies and Further Longitudinal Evidence

Behavioural Neurology, Volume 2015, Issue 1, 2015., 2015
The role of colour in object recognition is controversial; in this study, a critical review of previous studies, as well as a longitudinal study, was conducted. We examined whether colour benefits the ability of Alzheimer’s disease (AD) patients and normal controls (NC) when naming items differing in colour diagnosticity: living things (LT) versus ...

Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations

Biotropica, Volume 57, Issue 6, November 2025.
In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.

Tropical Land‐Use Change Disrupts Zeta‐Diversity Across Taxa

Global Change Biology, Volume 31, Issue 5, May 2025.
We studied birds, dung beetles, and orchids across natural and human‐transformed habitats in the Colombian Andes to understand how land‐use change affects biodiversity. We found that deforestation simplifies ecological communities and reduces both rare and widespread species, especially orchids.
