Pseudoexfoliation syndrome (PXS) and pigment dispersion syndrome (PDS) are two of the commonest disorders to produce secondary open-angle glaucoma through trabecular meshwork blockage. Each is a defined clinical entity, and while genetics likely play a significant role in the pathogenesis of both, the specific genes involved appear to be distinct. There is surprisingly little published in the l...

There is great interest in educationa l leadership in the early part of the 21st cen tury because of the widespread belief that the quality of leadership makes a significant difference to school and student outcomes. There is also increasing recognition that schools require effective leaders and managers if they are to provide the best possib le education f or their learners . Schools need trai...

Erythema multiforme may be placed on a disease continuum that includes Stevens-Johnson syndrome and toxic epidermal necrolysis. It was first described in 1866 by Hebra as a skin disease with symmetrically distributed red papules, evolving within several days to form annular or iris-like shapes or blisters. The term multiforme described this evolution of primary lesions into different forms. In ...

As one of the simple and efficient routes to access two-dimensional materials, liquid exfoliation has received considerable interest in recent years. Here, we reported on high-efficient liquid exfoliation of hexagonal boron nitride nanosheets (BNNSs) using monoethanolamine (MEA) aqueous solution. The resulting BNNSs were evaluated in terms of the yield and structure characterizations. The resul...

INTRODUCTION True exfoliation of lens capsule is a relatively rare disorder that has a thin, fluttering membrane in the anterior chamber, mainly located in the pupil area, which is believed to have split from the anterior lens capsule. CASE REPORT The authors present here a patient with true exfoliation and primary angle closure glaucoma in both eyes, the ultrastructure of one eye revealed th...

We demonstrated a facile and efficient approach for the fabrication of few-layer graphene in DMF and graphite nanosheets in water with the assistance of high pressure homogenization. This work provides a physical perspective for understanding the exfoliation of other layered materials in liquid phase exfoliation.

Exfoliation of a family of polyacetylenic porous layered covalent organic frameworks by means of a simple sonication procedure results in the obtention of nanolayer structures as observed by AFM and TEM measurements. Systematic AFM analysis of the isolated nanostructures reveals that the degree of exfoliation depends on the polymer architecture, thinner layers being observed when the pore size ...

We report a facile method for the production of graphene sheets through the liquid-phase exfoliation of graphite in organic solvents with addition of NaOH. NaOH was found to be intercalated into the interplanar spaces of graphite, and greatly improves exfoliation efficiency up to 20 times.

Colonization and disruption of the epithelium is a major infection mechanism of mucosal pathogens. The epithelium counteracts infection by exfoliating damaged cells while maintaining the mucosal barrier function. The sexually transmitted bacterium Neisseria gonorrhoeae (GC) infects the female reproductive tract primarily from the endocervix, causing gonorrhea. However, the mechanism by which GC...
