A two-dimensional pore-scale numerical model was developed to evaluate the dynamics of preferential flow paths in porous media caused by bioclogging. The liquid flow and solute transport through the pore network were coupled with a biofilm model including biomass attachment, growth, decay, lysis, and detachment. Blocking of all but one flow path was obtained under constant liquid inlet flow rat...

purpose: to compare the anatomical results of scleral buckling with or without retinopexy and to assess the effect of retinopexy on outcomes of the operation.  methods: this interventional case series was performed on 22 patients undergoing scleral buckling (segmental or encircling) with or without subretinal fluid drainage and without any type of retinopexy and 33 patients who received transsc...

objective: to determine the sensivity and specifity of ocular ultrasonography in detecting vitreoretinal lesion prior to deep vitrectomy in patients with opaque media. method: the hospital records of patients undergoing deep vitrectomy in a defined period at shiraz khalili hospital were reviewed. sonographic reports given by a sonologist and operation reports given by a vitreoretinal fellowship...

A model was developed to describe the overall dissolution kinetics of semicrystalline PVA gels prepared by freezing and thawing techniques. The dissolution process was described as a three-step mechanism: detachment-, diffusion-, and disentanglement-controlled dissolution. The unfolding of crystalline regions due to detachment and diffusion was calculated. The lamellar thickness of a PVA crysta...

The term toxic epidermal necrolysis (TEN) was introduced in 1956 by Lyell to describe four patients with a syndrome featured by extensive epidermal detachment with mucous membrane involvement, leaving the skin surface looking scalded. Necrolysis denotes necrosis and full thickness detachment of the epidermis. Toxic means severe constitutional symptoms and complications. Stevens-Johnson syndrome...
