Evolution and Functional Diversification of the GLI Family of Transcription Factors in Vertebrates

Evolutionary Bioinformatics, 2009
Background: In vertebrates the “SONIC HEDGEHOG” signalling pathway has been implicated in cell-fate determination, proliferation and the patterning of many different cell types and organs.

TALE-teller: Tendon-Actuated Linked Element Robotic Testbed for Investigating Tail Functions [PDF]

arXiv
Tails serve various functions in both robotics and biology, including expression, grasping, and defense. The vertebrate tails associated with these functions exhibit diverse patterns of vertebral lengths, but the precise mechanisms linking form to function have not yet been established.

Origin and diversification of steroids: Co-evolution of enzymes and nuclear receptors [PDF]

, 2010
Recent sequencing of amphioxus and sea urchin genomes has provided important data for understanding the origins of enzymes that synthesize adrenal and sex steroids and the receptors that mediate physiological response to these vertebrate steroids ...

Host ecotype and rearing environment are the main drivers of threespine stickleback gut microbiota diversity in a naturalistic experiment

Royal Society Open Science
Host–microbiota interactions play a critical role in the hosts’ biology, and thus, it is crucial to elucidate the mechanisms that shape gut microbial communities.

HealthiVert-GAN: A Novel Framework of Pseudo-Healthy Vertebral Image Synthesis for Interpretable Compression Fracture Grading [PDF]

arXiv
Osteoporotic vertebral compression fractures (VCFs) are prevalent in the elderly population, typically assessed on computed tomography (CT) scans by evaluating vertebral height loss. This assessment helps determine the fracture's impact on spinal stability and the need for surgical intervention.

Decoding Dmrt1: Insights into vertebrate sex determination and gonadal sex differentiation [PDF]

arXiv
Dmrt1 is pivotal in testis formation and function by interacting with genes crucial for Sertoli cell differentiation. Dmrt1, or Sox9, forms a conserved antagonistic interaction with Foxl2 across mammals. Across 128 vertebrate species, Dmrt1 exhibits sexually dimorphic expression, implicating its role in master regulation of sex determination and ...

Pharmacological properties of the repellent secretion of Zonocerus variegatus (L.) (Orthoptera: Prygomorphidae)

Revista de Biología Tropical, 1999
The odours of the whole body and the secretion of Zonocerus variegatus were easily recognised and perceived by human volunteers. However, the secretion odour is not related to the odour of the food plant consumed by the grasshopper.
