Autoregulation of blood flow is a marvelous phenomenon balancing blood supply and tissue demand. Although many chemically-based explanations for this phenomenon have been proposed and some of them are commonly used today, biomechanical aspects of this phenomenon was neglected. The biomechanical aspect provides insights to us to model vessel diameter changes(More)
Keywords: Computer aided diagnosis Diabetic retinopathy Fluorescein angiography Fundus images Radon transform Microaneurysms a b s t r a c t Early detection of microaneurysms (MAs), the first sign of Diabetic Retinopathy (DR), is an essential first step in automated detection of DR to prevent vision loss and blindness. This study presents a novel and(More)
The use of nutrition in medical practice has a long history dating back to 6000 years. The great Persian chemist, physician, and philosopher, Rhazes (865-925 AD), wrote over 200 books in different branches of science. Some of his work drew attention to the notion that nutrition is an important part of treating diseases and health care procedures. Rhazes(More)
BACKGROUND Nowadays, magnetic nanoparticles (MNPs) have received much attention because of their enormous potentials in many fields such as magnetic fluid hyperthermia (MFH). The goal of hyperthermia is to increase the temperature of malignant cells to destroy them without any lethal effect on normal tissues. To investigate the effectiveness of cancer(More)
BACKGROUND Clay has been used for its nutrition, cosmetic, and antibacterial properties for thousands of years. Its small particle size, large surface area, and high concentration of ions have made it an interesting subject for pharmaceutical research. There have been studies on scavenging foreign substances and antibacterial properties of clay minerals.(More)
(177)Lu-ethylenediaminetetramethylene phosphonic acid (EDTMP) is presently suggested as an excellent bone seeking radionuclide for developing metastatic bone pain (MBP) palliation agent owing to its suitable nuclear decay characteristics. To find the exact dosage and its efficiency, this clinical study was performed on the human being, using (177)Lu-EDTMP(More)
A common cause of blindness worldwide is glaucoma. It is characterized by visual field loss which is caused by optic nerve damage leading to glaucomatous optic neuropathy (GON). Modelling of GON development may be helpful for designing strategies to decelerate the rate of GON progression and prevent GON development at early stages. Attempts to complete the(More)
BACKGROUND Two-dimensional projection radiographs have been traditionally considered the modality of choice for cephalometric analysis. To overcome the shortcomings of two-dimensional images, three-dimensional computed tomography (CT) has been used to evaluate craniofacial structures. However, manual landmark detection depends on medical expertise, and the(More)
BACKGROUND Lead-based shields are the standard method of intraoperative radiation protection in the radiology and nuclear medicine department. Human lead toxicity is well documented. The lead used is heavy, lacks durability, is difficult to launder, and its disposal is associated with environmental hazards. The aim of this study was to design a lead free(More)
Shortening of metacarpals is a useful diagnostic marker in patients with pseudohypoparathyroidism type Ia (PHP-Ia) with Albright's hereditary osteodystrophy (AHO) phenotype or pseudopseudohypoparathyroidism (PPHP). There are very rare reports of metacarpals shortening in idiopathic primary hypoparathyroidism (IPH) cases in the literature. Here we described(More)
