ProbCD: enrichment analysis accounting for categorization uncertainty [PDF]

open access: yes, 2007
As in many other areas of science, systems biology makes extensive use of statistical association and significance estimates in contingency tables, a type of categorical data analysis known in this field as enrichment (also over-representation or ...

Hepatica transsilvanica Fuss (Ranunculaceae) is an Allotetraploid Relict of the Tertiary Flora in Europe – Molecular Phylogenetic Evidence

open access: yesActa Societatis Botanicorum Poloniae, 2020
The Hepatica section Angulosa consists of mainly tetraploid (2n = 28) species that are distributed disjunctly throughout Eurasia. Karyological evidence proves the hybrid origin of the polyploid species of this section. Hepatica transsilvanica is a member

Human brain evolution and the "Neuroevolutionary Time-depth Principle:" Implications for the Reclassification of fear-circuitry-related traits in DSM-V and for studying resilience to warzone-related posttraumatic stress disorder. [PDF]

open access: yes, 2006
The DSM-III, DSM-IV, DSM-IV-TR and ICD-10 have judiciously minimized discussion of etiologies to distance clinical psychiatry from Freudian psychoanalysis.

A zoogeographic model for the evolution of diversity and endemism in Madagascar

open access: yesEcography, EarlyView.
The delineation of zoogeographic regions is essential for understanding the evolution of biodiversity. Madagascar, characterized by high levels of endemism and habitat diversity, presents unique challenges and opportunities for such studies. Traditional global zoogeographic classifications, largely based on vertebrates, may overlook finer‐scale ...

A Phylogenomic Backbone for Gastropod Molluscs

open access: yesSystematic Biology, 2022
AbstractGastropods have survived several mass extinctions during their evolutionary history resulting in extraordinary diversity in morphology, ecology, and developmental modes, which complicate the reconstruction of a robust phylogeny. Currently, gastropods are divided into six subclasses: Caenogastropoda, Heterobranchia, Neomphaliones, Neritimorpha ...

Contamination in Reference Sequence Databases: Time for Divide-and-Rule Tactics

open access: yesFrontiers in Microbiology, 2021
Contaminating sequences in public genome databases is a pervasive issue with potentially far-reaching consequences. This problem has attracted much attention in the recent literature and many different tools are now available to detect contaminants ...

Gene Function Classification Using Bayesian Models with Hierarchy-Based Priors [PDF]

open access: yes, 2006
We investigate the application of hierarchical classification schemes to the annotation of gene function based on several characteristics of protein sequences including phylogenic descriptors, sequence based attributes, and predicted secondary structure.

De Novo Whole Genome Assemblies of Unusual Case‐Making Caddisflies (Trichoptera) Highlight Genomic Convergence in the Composition of the Major Silk Gene (h‐fibroin)

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
The major silk gene, h‐fibroin, was annotated in high‐quality genomes of two unusual case‐making Trichoptera. H‐Fibroin of Limnocentropus insolitus shows a similar amino acid composition to other case‐making species, while the amino acid composition of h‐fibroin of Phryganopsyche brunnea resembles that of retreat‐making species.

Algebraic tools in phylogenomics.

open access: yes, 2023
En aquesta tesi interdisciplinar desenvolupem eines algebraiques per a problemes en filogenètica i genòmica. Per estudiar l'evolució molecular de les espècies sovint s'usen models evolutius estocàstics. L'evolució es representa en un arbre (anomenat filogenètic) on les espècies actuals corresponen a fulles de l'arbre i els nodes interiors ...

Integrated Analysis of Metabolome and Transcriptome Reveals the Difference in Flavonoid Biosynthesis between the Red- and White-Sarcocarp Pomelo Fruits

open access: yesMetabolites, 2022
Flavonoids are bioactive secondary metabolites that play multiple roles in plants. However, studies on the flavonoid accumulation of the pomelo fruit are rare.
