purpose : to evaluate the retinal nerve fiber layer (rnfl) and central corneal thickness (cct) in patients with exfoliation syndrome (xfs) methods : in this comparative case series we measures rnfl thickness and cct 30 patients with xfs and 30 age and sex matched healthy subjects who met the inclusion criteria. results : average rnfl in xfs group were significantly thinner than controls (94.36±...

THE NORMAL EXFOLIATION PROCESS Exfoliation occurs naturally as outworn stratum corneum cells detach and are removed from the skin’s surface. Replacement of stratum corneum cells occurs by a self-renewal process as epidermal cells move upward from the basal layer, the stratum basalis, and through the subsequent two layers, the stratum spinosum and stratum granulosum, to reach the stratum corneum...

Exfoliation of graphite nanofibers (GNF) expands the interplanar spacing of the GNF which leads to increased hydrogen storage. The exfoliation technique plays a large role in the resulting GNF microstructure, surface area, and hydrogen storage properties. Variations in preparation conditions expand the GNF lattice from 3.4 Å to over 500 Å. The BET surface area of the exfoliated GNF increases as...

Colonization of mucosal surfaces is the key initial step in most bacterial infections. One mechanism protecting the mucosa is the rapid shedding of epithelial cells, also termed exfoliation, but it is unclear how pathogens counteract this process. We found that carcinoembryonic antigen (CEA)-binding bacteria colonized the urogenital tract of CEA transgenic mice, but not of wild-type mice, by su...

Computational screening of battery electrolyte components is an extremely challenging task because very complex features like solid-electrolyte-interphase (SEI) formation and graphite exfoliation need to be taken into account at least in the final screening stage. We present estimators for both SEI formation and graphite exfoliation based on a combinatorial approach using quantum chemistry calc...

Cytologic observation was made of the smears from the epipharyngeal mucosa in 160 cases of epipharyngitis, with some reference to the relationship of its results with the clinical symptom. The findings obtained are as follows. 1) The exfoliation of ciliated epithelial cells was of a much higher degree as compared with the normal cases. 2) A fairy good parallel relationship was found between the...

In this study, free-standing expanded graphite chitosan (EG-chitosan) nanocomposite films have been prepared using a novel green and simple preparation method, starting from a commercial expandable graphite (GIC). The in situ exfoliation of GIC by a solvent-free sonication method was monitored as a function of the process parameters using X-ray diffraction (XRD), transmission electron microscop...

This project studies the synthesis process of 2-D nanostructure of Bismuth oxycholride(BiOCl). The experiment involves synthesis of BiOCl particles and its exfoliation steps. BiOCl will be synthesized from Bismuth Nitrate (Bi(NO3)3) or Bismuth Cholride(BiCl3) with water, and Hydrochloric acid(HCl). Synthesized particles will be dispersed in Methyl Amine-Methanol solution and subjected to sonica...

Alum-precipitated exfoliatin was found to be an efficient antigen for eliciting high titers of neutralizing antibody in rabbits. Antitoxin thus produced, and transferred passively, was shown to protect neonatal mice against challenge with two to three lethal doses of preformed exfoliatin even when administration was delayed until 15 min before exfoliation began in control animals. The same dose...
