A review of all penetrating eye injuries treated at the Manchester Royal Eye Hospital over four years (1 January 1982-31 December 1985) was undertaken. A total of 202 penetrating eye injuries were seen of which 68 (34%) were in children under the age of 15 years. Airgun, dart, and knife injuries accounted for 28 (41%) of the injuries. Thirty seven patients (54%) achieved a good visual result (6...

We investigated whether a cell-penetrating peptide linked via a disulfide bond to a fluorophore-labeled cargo peptide can be used to interrogate changes in cellular redox state. A fluorescence resonance energy transfer (FRET) pair was constructed so that the cargo peptide was labeled with fluorescein amidite (FAM) and the cell-penetrating peptide was attached to a quencher. Incubation of cells ...

To evaluate the possible postoperative outflow from the anterior chamber of the eye after filtration surgery, a mathematical model based on fluid mechanical principles and clinical data is proposed. Two ophthalmic surgical procedures, non-penetrating deep sclerectomy and trabeculectomy, were analyzed. Based on mathematical modeling, the amount of postoperative outflow through the fistula (after...

AIM To investigate the potential usefulness of contrast-enhanced three-dimensional (3D) power Doppler sonography in the differentiation of benign and malignant adnexal lesions. METHODS Thirty one patients with complex adnexal lesions of uncertain malignancy at transvaginal B-mode and/or color Doppler sonography were prospectively evaluated with three-dimensional power Doppler sonography befor...

A fully penetrating cut-off wall is a vertical seepage barrier that penetrates an aquifer and embedded in underlying aquitard to certain depth. Groundwater with this type of occurs through three paths: leakage the body aquifer, aquitard, under wall. Seepage first path can be simply treated as one-dimensional flow. However, due mutual influence latter two paths, problem complicated still needs s...

We report the case of an asymptomatic 47 year-old male patient who suffered a penetrating wound from a metallic foreign body that became embedded adjacent to the optic nerve for over thirty years, as well as the associated examination, imaging, and fundus photography. Intraorbital metallic foreign bodies can be well tolerated and may not require surgical intervention despite proximity to import...

Transportation problem is a linear programming which considers minimum cost for shipping a product from some origins to other destinations such as from factories to warehouse, or from a warehouse to supermarkets. To solve this problem simplex algorithmis utilized. In real projects costs and the value of supply and demands are fuzzy numbers and it is expected that optimal solutions for determini...
