This syndrome is a genetical disorder with symptoms result from deficit in the formation of connective tissue, especially collagen fiber biosynthesis. In these patients, there is hyperelasticity and fragility of the skin and mucosa. Injuries sever bleeding, internal bleeding and hemartrosis may be seen in these patients. Wounds leave scars after healing. There is recurrent dislocation of the jo...

In this study, Four Wave Mixing (FWM) characteristics in photonic crystal fibers are investigated. The effect of channel spacing, phase mismatching, and fiber length on FWM efficiency have been studied. The variation of idler frequency which obtained by this technique with pumping and signal wavelengths has been discussed. The effect of fiber dispersion has been taken into account; we obtain th...

در این پژوهش، تغییرات زمانی تپ‌های لیزری 2CO TEA که از اتاقکی حاوی گاز 6SF با فشار mbar 150-10 عبور می‌کند، شاریدگی‌های انرژی و فشارهای گازی مختلف بررسی شده است. نشان داده است برای هر شاریدگی، قطع معینی وجود دارد قطع، میخه تپ به طور کامل حذف می‌شود، درحالی دنباله دربرگیرنده کسر قابل توجهی اولیه آن است، برجامی‌ماند. شواهد تجربی برآمده داده‌های بیناب‌سنجی FTIR، گسست چندفوتونی مولکول‌های را پاسخگو...
Ehlers-Danlos syndrome is an inherited heterogeneous group of connective tissue disorders, characterized by abnormal collagen synthesis, affecting skin, ligaments, joints, blood vessels and other organs. It is one of the oldest known causes of bruising and bleeding and was first described by Hipprocrates in 400 BC. Edvard Ehlers, in 1901, recognized the condition as a distinct entity. In 1908, ...
PURPOSE To evaluate if using the Ehlers correction factor on the intraocular pressure (IOP) measured using the Goldmann applanation tonometer (GAT) improves its agreement with the PASCAL dynamic contour tonometer (DCT). PATIENTS AND METHODS A total of 120 eyes of 120 individuals were examined. Participants underwent IOP measurement with both the DCT and the GAT and central corneal thickness m...
Ehlers-Danlos syndrome is an inherited connective tissue disorder. Clinical manifestations of this syndrome are due to fragile connective tissue. Though many cardiovascular disorders in association with it have been reported, myocardial infarction is quite rare. In this report, two cases with type 4 Ehlers-Danlos syndrome and myocardial infarction are described. Patient 1 was a 30-year-old woma...
