Periodontology 2000, EarlyView.Abstract Orthodontic therapy applies forces to teeth, causing an inflammatory reaction in the periodontal ligament. This is repaired by remodeling of the periodontium, allowing tooth displacement. Although orthodontic therapy is mostly initiated during childhood and adolescence, the number of adults seeking this treatment is increasing as our society's

Adaptive evolution of Hox-gene homeodomains after cluster duplications
BMC Evolutionary Biology, 2006 Background Hox genes code for homeodomain-containing transcription factors that function in cell fate determination and embryonic development. Hox genes are arranged in clusters with up to 14 genes.

Applied Cognitive Psychology, Volume 40, Issue 6, November/December 2026.ABSTRACT Quizzing before (pretesting) or after (posttesting) studying is effective for learning, but via different underlying mechanisms: Posttests require students to actively recall information; pretests highlight knowledge gaps about the material. Instructional videos allow for studying these strategies because, unlike text‐based materials, they are

Microbial Biotechnology, Volume 19, Issue 11, November 2026.Proteomics of the aerobic carboxydotroph Hydrogenophaga pseudoflava across trophic conditions revealed that an unphysiological CO concentration causes a redox imbalance and stress response. CO dehydrogenase I and the membrane‐bound hydrogenase were essential for CO and H2 oxidation, respectively, whereas the soluble hydrogenase likely supports redox ...

Trichomes in Plant Defence, Development and Metabolic Integration Under Environmental Stress
Plant, Cell &Environment, Volume 49, Issue 11, Page 8437-8453, November 2026.ABSTRACT Among various plant defence strategies, trichomes are tiny hair‐like structures on the epidermis that aid in defence, environmental adaptation and the production of valuable secondary metabolites. This review features trichomes as frontline guards for plant survival, integrating their structural, physiological and metabolic roles in ...

Evolutionary lability in Hox cluster structure and gene expression in Anolis lizards
Evolution Letters, 2019 Hox genes orchestrate development by patterning the embryonic axis. Vertebrate Hox genes are arranged in four compact clusters, and the spacing between genes is assumed to be crucial for their function. The genomes of squamate reptiles are unusually rich

A general scenario of
BMC Evolutionary Biology, 2011 Background Hox genes are known to play a key role in shaping the body plan of metazoans. Evolutionary dynamics of these genes is therefore essential in explaining patterns of evolutionary diversity.

The significance of Hox gene collinearity
The International Journal of Developmental Biology, 2015 Arthropods and vertebrates inherited their Hox clusters from an ancestral cluster of at least six genes already present in their last common ancestor, Urbilateria. Clustering and a common transcriptional direction are both likely features of the way that the gene complex first arose in a process of tandem gene duplication.

Evolutionary plasticity in nematode Hox gene complements and genomic loci arrangement
Scientific ReportsHox genes are central to metazoan body plan formation, patterning and evolution, playing a critical role in cell fate decisions early in embryonic development in invertebrates and vertebrates.
