Embark on an exciting journey of discovery with our in-school enrichment program, 4-H Embryology in the Classroom! Designed for pre-K through high school teachers, this immersive experience brings the ...

The retina is a layered structure that lines the inner surface of the eye. It consists of layers of neurons: light-sensitive photoreceptor cells, bipolar cells, horizontal cells, amacrine cells ...

Retinal regeneration and visual recovery in a retinitis pigmentosa model mouse through administration of AAV2-Anti-PROX1 gene therapy. We demonstrate that after administration of adeno-associated ...

Posterior vitreous detachment (PVD) occurs when the vitreous—a gel-like fluid in the eye—detaches from the retina. This results in eye floaters and flashes of light that can be annoying but is usually ...

The zebrafish mutation m865 affects formation of dopaminergic neurons and neuronal survival, and maps to a genetic interval containing the sepiapterin reductase locus.

Animal models using pregnant mice, rats, guinea pigs, hamsters, and rabbits are often used to determine reproductive toxicity in pre-clinical testing and development of new drugs. Yet, these models ...

It is estimated that more and more couples suffer from fertility and pregnancy maintenance disorders. It is associated with impaired androgen secretion, which is influenced by many factors, ranging ...

One notable missing feature in most ANN models is top-down feedback, i.e. projections from higher-order layers to lower-order layers in the network. Top-down feedback is ubiquitous in the brain, and ...

The volumes were obtained from 3D models. DRA – dorsal rim ommatidia in general (DRAm and DRA+); DRAm – dorsal rim area ommatidia (morphological specialization); DRA+ – transitional zone ommatidia; ...

Macular edema is swelling in the eye's retina that causes blurry vision but can progress to more serious vision loss. The most common condition associated with macular edema is diabetic retinopathy, ...
