Urolithins are microflora metabolites of dietary ellagic acid derivatives, such as ellagitannins. [1] They are produced in the gut , and found in the urine in the form of urolithin B glucuronide after absorption of ellagitannins-containing foods, such as pomegranate . [ 2 ]
Pomegranate fruits, walnuts, and raspberries are sources of ellagitannins. [4] [5] [6] Ellagitannins are hydrolyzed in the gut to release ellagic acid, which is further processed by the gut microflora into urolithins through the loss of one of its two lactones and by successive removal of hydroxyl groups.

The preorbital gland is a paired exocrine gland found in many species of artiodactyls, which is homologous to the lacrimal gland found in humans. These glands are trenchlike slits of dark blue to black, nearly bare skin extending from the medial canthus of each eye.
The vitreous fluid is not present at birth (the eye being filled with only the gel-like vitreous body), but found after age 4-5, and increases in size thereafter. [1] Produced by cells in the non-pigmented portion of the ciliary body, the vitreous humour is derived from embryonic mesenchyme cells, which degenerate after birth. [1]
— The entrance to a lone corridor led researchers into a lost ancient Egyptian royal tomb — once located beneath two waterfalls in Egypt’s Valley of the Kings — that they say belonged to ...
The blood–ocular barrier is a barrier created by endothelium of capillaries of the retina and iris, ciliary epithelium and retinal pigment epithelium. [1] It is a physical barrier between the local blood vessels and most parts of the eye itself, and stops many substances including drugs from traveling across it. [2]
