Coordination of Foliar and Wood Anatomical Traits Contributes to Tropical Tree Distributions and Productivity along the Malay-Thai Peninsula [PDF]

open access: yes, 2009
Drought is a critical factor in plant species distributions. Much research points to its relevance even in moist tropical regions. Recent studies have begun to elucidate mechanisms underlying the distributions of tropical tree species with respect to ...

Population-scale organization of cerebellar granule neuron signaling during a visuomotor behavior. [PDF]

open access: yes, 2017
Granule cells at the input layer of the cerebellum comprise over half the neurons in the human brain and are thought to be critical for learning. However, little is known about granule neuron signaling at the population scale during behavior.

A voxelwise approach to determine consensus regions-of-interest for the study of brain network plasticity

open access: yesFrontiers in Neuroanatomy, 2015
Despite exciting advances in the functional imaging of the brain, it remains a challenge to define regions of interest (ROIs) that do not require investigator supervision and permit examination of change in networks over time (or plasticity).

Adaptive leaf anatomical characteristics of Brachiaria ruziziensis genotypes (Poaceae) in different environments - doi: 10.4025/actascibiolsci.v35i4.18265

open access: yesActa Scientiarum: Biological Sciences, 2013
Studies on morphological plasticity are extremely important to plant breeding seeking to optimize genotype interactions with their environments. The present study evaluated 38 genotypes of Brachiaria ruziziensis cultivated during the rainy (October to ...

Should Root Plasticity Be a Crop Breeding Target?

open access: yesFrontiers in Plant Science, 2020
Root phenotypic plasticity has been proposed as a target for the development of more productive crops in variable environments. However, the plasticity of root anatomical and architectural responses to environmental cues is highly complex, and the ...

A simple rule for axon outgrowth and synaptic competition generates realistic connection lengths and filling fractions [PDF]

open access: yes, 2009
Neural connectivity at the cellular and mesoscopic level appears very specific and is presumed to arise from highly specific developmental mechanisms.

Liquid biopsy epigenetics: establishing a molecular profile based on cell‐free DNA

open access: yesMolecular Oncology, EarlyView.
Cell‐free DNA (cfDNA) fragments in plasma from cancer patients carry epigenetic signatures reflecting their cells of origin. These epigenetic features include DNA methylation, nucleosome modifications, and variations in fragmentation. This review describes the biological properties of each feature and explores optimal strategies for harnessing cfDNA ...

Extensive spontaneous plasticity of corticospinal projections after primate spinal cord injury. [PDF]

open access: yes, 2010
Although axonal regeneration after CNS injury is limited, partial injury is frequently accompanied by extensive functional recovery. To investigate mechanisms underlying spontaneous recovery after incomplete spinal cord injury, we administered C7 spinal ...

A perspective on cortical layering and layer-spanning neuronal elements [PDF]

open access: yes, 2018
This review article addresses the function of the layers of the cerebral cortex. We develop the perspective that cortical layering needs to be understood in terms of its functional anatomy, i.e., the terminations of synaptic inputs on distinct cellular ...

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

open access: yesMolecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...
