Papillomas And Carcinomas Of The Choroid Plexus: Histological And Immunohistochemical Studies And Comparison With Normal Fetal Choroid Plexus [PDF]

, 2015
Background: Choroid plexus tumors are rare. Results on immunohistochemical features are scanty and controversial even regarding normal plexus. Method: Thirteen cases of choroid plexus tumors and five samples of normal fetal choroid plexus were submitted ...

Anatomy of spinal CSF loss in the American alligator (Alligator mississippiensis)

Journal of Anatomy, Volume 246, Issue 4, Page 575-584, April 2025.
India ink introduced into the cranial cerebrospinal fluid (CSF) compartment of Alligator diffuses along the spinal cord and exits the spinal compartment using perineural flow, resulting in a prominent “ink cuff” forming at the base of the spinal nerve. In Alligator, the region of the ink cuff is drained by a small lymphatic vessel.

Neural modulation of ocular immunity: Exploring a sympathetic‐macrophage neuroimmune link in the human ciliary body

Journal of Anatomy, EarlyView.
Using microscopy and 3D confocal imaging on seven cadaveric eyes, we identified sympathetic nerves closely associated with β₂‐adrenergic receptor‐expressing macrophages in the human ciliary body (CB). These findings suggest a sympathetic‐macrophage neuroimmune link in the CB, potentially influencing ocular inflammation and degeneration, warranting ...

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

Journal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.

The MacBrain Resource Center (MBRC) rhesus macaque embryonic brain histology datasets

Journal of Anatomy, EarlyView.
We introduce the MacBrain Resource Center (MBRC) Collections of rhesus macaque embryonic brain tissue. Here, we illustrate histo‐ and immunohistology from our dynamically growing Collection 6, which currently contains >10,000 zoomable and downloadable images from n = 14 male and female embryos from early to late in gestation.

Pharmacokinetics of Diclazuril in the Plasma and Cerebrospinal Fluid of Healthy Adult Horses After a Single Oral Dose Administered as a Pelleted Topdressing

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Equine protozoal myeloencephalitis can cause acute infections with rapid onset of neurologic signs, necessitating immediate empiric therapy with antiprotozoal medication. The objective of the study was to identify when concentrations of diclazuril reached the MIC of Sarcocystis neurona in CSF (1 ng/mL) of healthy adult horses after a single ...

Techniques for subretinal injections in animals

Veterinary Ophthalmology, Volume 28, Issue 2, Page 506-518, March 2025.
Abstract Subretinal injections are not commonly performed during clinical treatment of animals but are frequently used in laboratory animal models to assess therapeutic efficacy and safety of gene and cell therapy products. Veterinary ophthalmologists are often employed to perform the injections in the laboratory animal setting, due to knowledge of ...

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges

Experimental Physiology, EarlyView.
Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.
