in order to study the effect of ultrasound (us) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group i. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= i) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a gigli saw. the test...

introduction this paper proposes the concept of autonomous drug-encapsulated nanoparticle (adenp) as a novel non-invasive approach to prevent atherosclerosis. adenp consists of three simple units of sensor, controller (computing), and actuator. the hardware complexity of adenp is much lower than most of the nanorobots, while the performance is maintained by the synergism in the swarm architectu...

abstract : horizontal root fractures in permanent teeth are uncommon injuries among dental traumas. the principle of treating horizontal root fractures of permanent teeth is repositioning and fixation of fractured segment. diagnosis of tooth fractures based on radiographic findings and the fracture healing process are affected by factors before and after injury. the present case reports the tre...

Natural polymeric hydrogels with self-healing capability that can recover the functionalities and structures of gels after damage are extremely attractive due to their emerging applications in the biomedical field. Here we report a self-healable polymeric hydrogel by self-crosslinking two natural polymers acrylamide-modified chitin (AMC) containing amino groups and oxidized alginate containing ...

wounds and wound healing have always been one of the most important subjects that experimental researches were dedicated to. simvastatin has been used for long as a common lipid lowering agent which was reported to have some pleiotropic effects such as antioxidation, anti-inflammation and immunomodulation. in this study we aimed to determine the effect of simvastatin on wound healing process in...

burns are a worldwide problem. the incidence of severe burns has been higher than the combined incidence of tuberculosis and hiv infections. throughout history there have been many different treatments prescribed for burns. the canon is the masterpiece of avicenna’s medical books. the canon includes a description of 785 simple drugs. avicenna believed in burn treatment, which follows two goals....

Wireless sensor networks (WSNs) are key technology enablers for the current and near future security and surveillance systems. In order to build realtime, multi-modal, high resolution monitoring in those systems, WSN applications need to address critical challenges such as autonomy, scalability, self-healing and simplicity. Based on the observation that various biological systems have developed...

In recent years corrosion-resistant self-healing coatings have witnessed strong growth and their successful laboratory design and synthesis categorises them in the family of smart/multi-functional materials. Among various approaches for achieving self-healing, microcapsule embedment through the material matrix is the main one for self-healing ability in coatings. The present work focuses on opt...

Autonomously detecting and recovering from faults is one approach for reducing the operational complexity and costs associated with managing computing environments. We present a novel methodology for autonomously generating investigation leads that help identify systems faults, and extends our previous work in this area by leveraging Restricted Boltzmann Machines (RBMs) and contrastive divergen...
