Amniotic membranes (AMs) are widely used as a corneal epithelial tissue carrier in reconstruction surgery. However, the engineered tissue transparency is low due to the translucent thick underlying AM stroma. To overcome this drawback, we developed an ultra-thin AM (UAM) by using collagenase IV to strip away from the epithelial denuded AM (DAM) some of the stroma. By thinning the stroma to abou...

Comparison of the deduced amino acid sequences of DNA-[N6-adenine]-methyltransferases has revealed several conserved regions. All of these enzymes contain a DPPY [or closely related] motif. By site-directed mutagenesis of a cloned T4 dam gene, we have altered the first proline residue in this motif [located in conserved region IV of the T4 Dam-MTase] to alanine or threonine. The mutant enzymic ...

PURPOSE To investigate basement membrane (BM) formation during ex vivo expansion of limbal corneal epithelial cells on intact amniotic membrane (iAM) and epithelially denuded (d)AM. METHODS Human limbal explants were cultured on iAM and dAM. Expression of BM components, including laminin-5, type IV collagen, type VII collagen, perlecan, integrin alpha6, and epithelial cell differentiation mar...

Water resources are vital to the survival of living organisms and contribute substantially development various sectors. Climatic diversity, topographic conditions, uneven distribution surface water flows have made reservoirs one primary supply in Iran. This study used Landsat 5, 7, 8 data Google Earth Engine (GEE) for supervised monitoring dynamics reservoir eight Iranian dams (Karkheh, Karun-1...

The Sacachún commune in Ecuador currently faces a lack of water for its agricultural development; this reduces possibilities socio-economic development and causes migration to urban areas. This research proposes presa colinar (hill dam) design that uses ancestral knowledge classic engineering techniques promote use during the dry season semi-arid regions. methodology consisted of: (i) systemati...

background alkylphenol polyethoxylates (apneos) and their metabolites disposal from sewage treatment plants (stp) are of particular concern due to their persistence, toxicity to aquatic organisms, and a potential endocrine disruptor. in this work, we focused on the determination of nonylphenol (np) and nonylphenol polyethoxylate (npneos) in water were collected from karun river. material and me...

In this paper, a many-objective optimization algorithm was developed using SPEA2 for system of four reservoirs in the Karun basin, including hydropower, municipal and industrial, agricultural, environmental objectives. For purpose, 53 years available data, hedging rules were two modes: with without applying fuzzy logic. used to optimize coefficients first 43 data last 10 test optimized rule cur...
