Abstract Proximity search is an iterative method to solve complex mathematical programming problems. At each iteration, the objective function of problem at hand replaced by Hamming distance a given solution, and cutoff constraint added impose that any new obtained solution improves value. A mixed integer solver used find feasible this modified problem, yielding improved original problem. This ...
Vascular injuries in conjunction with low-energy geriatric hip fractures, although uncommon, can be life-threatening. Furthermore, vascular injuries are usually iatrogenic, related to malpositioning of percutaneous reduction aids, aberrant drilling, or poorly sized implants. The authors describe an older woman who had a low-energy pertrochanteric hip fracture. She was noted preoperatively to ha...
Cartilage oligomeric matrix protein (COMP/thrombospondin [TSP]-5) belongs to the thrombospondin gene family and is an extracellular glycoprotein found predominantly in cartilage and tendon. To date, there is limited evidence of COMP/TSP-5 expression outside of the skeletal system. The aim of the present study was to investigate the expression of COMP/TSP-5 in cultured human vascular smooth musc...
BACKGROUND The coexistence of an unstable spinal fracture with a pending aortic lesion is potentially catastrophic and a therapeutic challenge as to timing of treatment, assigning priorities and selecting the best approach. CASE REPORT A 41 year-old healthy male victim of bike accident. Imaging revealed a fracture of 6th and 7th thoracic vertebrae with a bone fragment in close proximity to th...
vascular lesions rise from abnormalities in blood vessels or endothelial proliferation . capillary hemangiomas are formed by small capillaries surrounded by a layer of endothelial cells in a connective tissue stroma . various treatments are used for these conditions like excisional surgery , sclerotherapy, and recently laser irradiation. in this case study, we report successful treatment of int...
purpose : to report clinical and pathologic result of a young patient with isolated cavernous hemangioma of conjunctiva case report : a 26-year-old man who presented with smooth, red, lobular surface mass was seen in the bulbar conjunctiva in temporal side with engorged episcleral and conjunctival vessels around the lesion. excisional biopsy was performed. pathologist confirmed the diagnosis of...
The vascular endothelial growth factors VEGFA and VEGFC are crucial regulators of vascular development. They exert their effects by dimerization and activation of the cognate receptors VEGFR2 and VEGFR3. Here, we have used in situ proximity ligation to detect receptor complexes in intact endothelial cells. We show that both VEGFA and VEGFC potently induce formation of VEGFR2/-3 heterodimers. Re...
in this paper, based in the l ukasiewicz logic, the definition offuzzifying soft neighborhood structure and fuzzifying soft continuity areintroduced. also, the fuzzifying soft proximity spaces which are ageneralizations of the classical soft proximity spaces are given. severaltheorems on classical soft proximities are special cases of the theorems weprove in this paper.
