Aim and Background: There is little doubt that patients with low back pain (LBP) use their body differently in comparison with healthy individuals. The purpose of this review was to investigate changes in biomechanical perspective which may be present in athletes with LBP. Methods and Materials: TThe search strategy for this review consisted of an electronic database search of full text in PUBM...
Plaque hemorrhage in carotid artery disease: Pathogenesis, clinical and biomechanical considerations
دسته ای از ترکیبات شیمیائی که مخصوصا با گسترش زندگانی جدید (ماشینی)اهمیت فرآینده ای پیدامی کنند، افزودنیهای مختلف غذائی میباشند که در صنایع مربوطه بکار گرفته می شوند بکارگیری بخشی از این موا تحت عنوان طعم دهنده ها بمنظور تامین طعم و مزه طبیعی درفرآورده های صنعتی تقریبا اجتناب ناپذیر گشته و همگام با توسعه تولیدات روبه توسعه می رود. یک شناخت سیستماتیک و جامع از خواص و آثار اینگونه مواد طبیعتا مست...
Objectives Cage design and material properties play a crucial role in the long-term results, since interbody fusions using intervertebral cages have become one of the basic procedures in spinal surgery. Our aim is to design a novel Apatite-Wollastonite interbody fusion cage and evaluate its biomechanical behavior in silico in a segmental spinal model. Materials and Methods Mechanical properti...
Femoropopliteal lesions account for a significant proportion of endovascular interventions for peripheral artery disease in patients with disabling claudication or chronic limb ischemia. The femoropopliteal artery crosses two joint structures (hip and knee joints) and courses through the muscular adductor canal in the thigh, which places the artery at increased biomechanical stress. There is a ...
Stent fracture is one of the major factors compromising implanted stent patency due to its consequences including in-stent restenosis, thrombosis, perforation, and migration. Stent fracture can occur from stress (extrinsic or intrinsic) and biomechanical forces at different implantation sites. We report on 2 cases of stent fractures and pertinent literature. One patient, a 75-year-old male, pre...
Sustained hypertension is associated with a reduction in large artery compliance. However, we previously showed that, at the site of the radial artery, a distal muscular artery, the compliance of hypertensive patients was not significantly different from those of normotensive controls when the two groups were studied at their respective mean arterial pressures, despite increased wall thickness ...
تأثیر Ferrule effect روی ثبات بیومکانیکی دندانهای بازسازی شده با پست و کور و کراون: مروری بر مقالات
Background and Aims: Preserving intact coronal and radicular tooth structure is considered to be crucial for the optimal biomechanical behavior of restored teeth .The ferrule effect has been extensively studied and still remains controversial from many perspectives. The purpose of this study was to summarize the results of different issues related to the ferrule effect and published in journa...
