Multi‐Omics Profiling Reveals Immunomodulatory and Pro‐Regenerative Effects of a Graphene Oxide–Collagen Scaffold in Massive Rotator Cuff Tears

Advanced Science, Volume 13, Issue 44, 7 August 2026.
A graphene oxide/collagen scaffold is developed for chronic massive rotator cuff tear repair. The scaffold improves compressive stability, supports reparative mesenchymal differentiation, and modulates the immune microenvironment. In chronic MRCT models, it reduces muscle degeneration, enhances tendon–bone regeneration, and improves functional recovery,

Analysis of spontaneous regeneration of olfactory structures with emphasis on myelination and re-innervation of cortical areas [PDF]

, 2013
Regeneration of the lateral olfactory tract (LOT) occurs spontaneously after transection in developing rats. In neonatally LOT-transected rats, we observed a newly formed myelinated tract near the rhinal sulcus.

Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece

The Anatomical Record, Volume 309, Issue 8, Page 2100-2123, August 2026.
The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

Hyperactive mTORC1 in striatum dysregulates dopamine receptor expression and odor preference behavior

Frontiers in Neuroscience
Mechanistic target of rapamycin (mTOR) plays an important role in brain development and synaptic plasticity. Dysregulation of the mTOR pathway is observed in various human central nervous system diseases, including tuberous sclerosis complex, autism ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

The Anatomical Record, Volume 309, Issue 8, Page 1937-1969, August 2026.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Differential potentiation of odor aversion and yawning by melanocortin 4 receptor signaling in distinct regions of the ventral striatum

Frontiers in Neuroscience
Although animal behavior is influenced by neuromodulatory signals, the underlying mechanism remains elusive. The ventral striatum, which consists of the olfactory tubercle (OT) and nucleus accumbens (NAc), promotes motivated behaviors and receives ...

Connectivity, plasticity, and function of neuronal circuits in the zebrafish olfactory forebrain [PDF]

, 2014
For most living animals such as worms, insects, fishes, rodents and humans, chemical cues from the environment (odorants) play critical roles in guiding behaviors important for survival, including preying, mating, breeding, and escaping.

CD73 is a major regulator of adenosinergic signalling in mouse brain.

PLoS ONE, 2013
CD73 (ecto-5'-nucleotidase) is a cell surface enzyme that regulates purinergic signalling by desphosphorylating extracellular AMP to adenosine. 5'-nucleotidases are known to be expressed in brain, but the expression of CD73 and its putative physiological

Gestational VPA exposure reduces the density of juxtapositions between TH+ axons and calretinin or calbindin expressing cells in the ventrobasal forebrain of neonatal mice

Frontiers in Neuroanatomy
Gestational exposure to valproic acid (VPA) is a valid rodent model of human autism spectrum disorder (ASD). VPA treatment is known to bring about specific behavioral deficits of sociability, matching similar alterations in human autism.

Corticofugal GABAergic projection neurons in the mouse frontal cortex

Frontiers in Neuroanatomy, 2015
Cortical projection neurons are classified by hodology in corticocortical, commissural and corticofugal subtypes. Although cortical projection neurons had been regarded as only glutamatergic neurons, recently corticocortical GABAergic projection neurons ...
