Periocular malignancy.
… this thesis focus on the management of periocular malignancy. The most common tumours to involve the eyelids in order of frequency are: basal cell carcinoma (90%), squamous cell carcinoma (5-8%), sebaceous gland carcinoma (2-3%) and melanoma (1%). The eyelids represent a high risk area …

Transcriptional profiles of differentiating periocular neural crest cells and the function of Nephronectin during chick corneal development
During eye formation, periocular neural crest cells (pNC) migrate and differentiate to form the anterior ocular structures. In the chick cornea, this involves two waves of migration that result in the formation of the corneal endothelium and stroma. Abnormalities in pNC migration lead to corneal …

An in vitro model of mouse corneal endothelial development Mohammed Mubeen Goolam.
… transition (MET) in mouse periocular mesenchyme cells to drive them to form fully differentiated adult corneal endothelial cells in culture. Periocular mesenchyme surrounding the optic cup was dissected from E12.5 and E13.5 mouse embryos and immortalised with the SV40 large …

An Investigation of the Role of Bacillus oleronius in the Pathogenesis of Rosacea
… from rosacea have symptoms that manifest in the periocular region, including irritation, inflammation of the eyelids (blepharitis), increased vascularisation of the ocular surface and in severe cases inflammation of the cornea (keratitis) can develop leading to sterile ulcers and visual …

An Associative Memory Trace in the Cerebellar Cortex
… demonstrate that paired peripheral forelimb and periocular stimulation, as well as paired direct stimulation of cerebellar afferent pathways (mossy and climbing fibres) consistently causes a gradual acquisition of an inhibitory response in Purkinje cell simple spike firing. The response also …

Drug delivery strategies to overcome ocular hypertension
… aggregates (CDAs). The first strategy involves a periocular hydrogel-nanoparticle composite designed for sustained, local delivery to the eye. Timolol prodrugs, synthesized to self-assemble into CDAs, were developed to avoid the systemic spikes in drug concentration associated with conventional …

Reiterative FGF signaling determines the identity and morphology of the lacrimal gland
… signaling to control expression of Fgf10 in the periocular mesenchyme. Loss of function ALX4/Alx4 mutation disrupted lacrimal gland development in both human and mouse. Our results reveal a FGF-Shp2-Alx4-Fgf10 axis in regulating neural crests during lacrimal gland development. In addition, we …
